ITEM 1.    BUSINESS

Company Overview

        We are one of the world's largest distributors and providers of comprehensive supply chain management services to the global aerospace industry on an annual sales basis. Our services range from traditional distribution to the management of supplier relationships, quality assurance, kitting, just-in-time, JIT, delivery and point-of-use inventory management. We supply over 575,000 active stock-keeping units, or SKUs, including hardware, chemicals, electronic components, bearings, tools and machined parts. In fiscal 2014, sales of hardware represented 62% of our net sales. We serve our customers under both (i) long-term contractual arrangements, or Contracts, which include JIT contracts, that govern the provision of comprehensive outsourced supply chain management services and long-term agreements, or LTAs, that typically set prices for specific products, and (ii) ad hoc sales. On February 28, 2014, 100% of the outstanding stock of Haas was acquired by the Company. In accordance with the Accounting Standards Codification, or ASC, 805, Business Combinations, the acquired assets and liabilities assumed have been recorded at fair value for the interests acquired.

        Founded in 1953 by the father of our current Chief Executive Officer, or CEO, Wesco has grown to serve over 8,300 customers, which are primarily in the commercial, military and general aviation sectors, including the leading original equipment manufacturers, or OEMs, and their subcontractors, through which we support nearly all major Western aircraft programs. We also service industrial customers, which include customers in the automotive, energy, pharmaceutical and electronics sectors. We have more than 2,700 employees and operate across 83 locations in 19 countries. The following charts illustrate the composition of our 2014 net sales based on our sales data.

    Hardware

        Sales of C class aerospace hardware represented approximately 62%, 83% and 82% of our fiscal 2014, 2013 and 2012 product sales, respectively. Fasteners, our largest category of hardware products, include a wide range of highly engineered aerospace parts that are designed to hold together two or more components, such as rivets (both blind and solid), bolts (including blind bolts), screws, nuts and washers. Many of these fasteners are designed for use in specific aircraft platforms and others can be used across multiple platforms. Materials used in the manufacture of these fasteners range from standard alloys, such as aluminum, steel or stainless steel, to more advanced materials, such as titanium, Inconel and Waspalloy.

Table of Contents

    Chemicals

        On February 28, 2014, we acquired Haas, a provider of chemical supply chain management services to the commercial aerospace, airline, military, automotive, energy, pharmaceutical and electronics sectors. As a result of our acquisition of Haas, our chemical product offerings include adhesives; sealants and tapes; lubricants; oil and grease; paints and coatings; industrial gases; coolants and metalworking fluids; and cleaners and cleaning solvents.

    Electronic Components

        We offer highly reliable interconnect and electro-mechanical products, including connectors, relays, switches, circuit breakers and lighted products. We also offer value-added assembled products including mil-circular and rack and panel connectors and illuminated push button switches. We maintain large quantities of connector components in inventory, which allows us to respond quickly to customer orders. In addition, our lighted switch assembly operation affords customers same day service, including engraving capabilities in multiple languages.

    Bearings

        Our product offering includes a variety of standard anti-friction products designed to both commercial and military aircraft specifications, such as airframe control bearings, rod ends, spherical bearings, ball bearing rod ends, roller bearings and bushings.

    Machined Parts and Other

        Machined parts are designed for a specific customer and are assigned unique OEM-specific SKUs. The machined parts we distribute include laser cut or stamped brackets, milled parts, shims, stampings, turned parts and welded assemblies made of materials ranging from high-grade steel or titanium to nickel based alloys.

        We stock a full range of tools needed for the installation of many of our products, including air and hydraulic tools as well as drill motors, and we also offer factory authorized maintenance and repair services for these tools. In addition to selling these tools, we also rent or lease these tools to our customers.

    Our Services

        In addition to our traditional distribution services, we have developed innovative value-added services, such as quality assurance, kitting and JIT supply chain management for our customers.

    Quality Assurance

        Our quality assurance, or QA, function is a key component of our service offering, with approximately 5% of our employees dedicated to this area. We believe we offer an industry-leading QA function as a result of our rigorous processes, sophisticated testing equipment and dedicated QA staff. Our superior QA performance is demonstrated by a comparison of our customers' aggregate rejection rate of the products we deliver, which was approximately 0.2% during fiscal 2014 (exclusive of the Haas business, which we acquired on February 28, 2014), to our rejection rate of the products we receive from our suppliers, which was approximately 2.0% during fiscal 2014 (exclusive of the Haas business).

        Our QA department inspects the inventory we purchase to ensure the accuracy and completeness of documentation. For many of our customers, these inspections are conducted at our in-house laboratory, where we operate sophisticated testing equipment. We also maintain an electronic copy of

6


Table of Contents

the relevant certifications for the inventory, which can include a manufacturer certificate of conformance, test reports, process certifications, material distributor certifications and raw material mill certifications. Our industry-leading QA capabilities also allow our JIT customers to reduce the number of personnel dedicated to the QA function and reduce the delays caused by the rejection of improperly inspected products.

    Kitting

        Kitting involves the packaging of an entire bill of materials or a complete "ship-set" of products, which reduces the amount of time workers spend retrieving products from storage locations. Kits can be customized in varying configurations and sizes and can contain up to several hundred different products. All of our kits and components contain fully certified and traceable products and are assembled by our full-service kitting department at our central stocking locations, or CSLs, or at our customer sites.

    JIT Supply Chain Management

        JIT supply chain management involves the delivery of products on an as-needed basis to the point-of-use at a customer's manufacturing line. JIT programs are designed to prevent excess inventory build-up and shortages and improve manufacturing efficiency. Each JIT contract requires us to maintain an efficient inventory tracking, analysis and replenishment program and is designed to provide high levels of stock availability and on-time delivery. We believe customers that utilize our comprehensive JIT supply chain management services are frequently able to realize significant benefits including:

    reduced inventory levels and lower inventory excess and obsolescence expense, in part because such customers only purchase what they need, and make more efficient use of their floor space;

    increased accuracy in forecasting and planning, resulting in substantially improved on-time delivery, reduced expediting costs and fewer disruptions of production schedules;

    improved quality assurance resulting in a substantial reduction in customer product rejection rates; and

    reduced administrative and overhead costs relating to procurement, QA, supplier management and stocking functions.

        Before signing a JIT contract, our customers typically experience outages of many SKUs and, in some cases, have up to a year's worth of inventory on hand. As part of our JIT programs, we generally assume the customer's existing inventory at the onset of the contract, immediately reducing their inventory on-hand and the associated management costs. Customer inventory is generally assumed on a consignment basis and is entered in our database in a distinct customer-specific "virtual warehouse." Software protocol in our IT systems requires the system to first "look" to a customer's consigned inventory when parts replenishment is required. In certain cases, we can sell this consigned inventory to our base of over 8,300 other active customers around the world, gradually drawing down the customer's inventory. As the consigned inventory for each SKU is exhausted, our stock of Wesco-sourced product reserve is then used for replenishment.

        Another key strength of our JIT programs is our ability to utilize highly scalable and customizable point-of-use systems to develop an efficient supply chain management system and automated replenishment solution for any number of SKUs. In order to minimize inventory on hand, certain indicators are used to trigger the replenishment of product from a supplying location to the location of consumption. Our "Twin-Bin" system is an example of such an indicator. A JIT program designed around a Twin-Bin system utilizes a specially-manufactured unit composed of two bins stacked on top

7


Table of Contents

of one another. In this system, a clear plastic bag, typically containing a 30-day supply of parts, is loaded in each bin. Production workers use all of the parts within the bottom bin before drawing a pullout slide between the two bins that drops the full plastic bag of parts from the top bin into the bottom bin. An empty top bin indicates the need to initiate replenishment of the parts and provides a clear visual management process on the manufacturing floor. All replenishment activity is done via hand-held scanners that transmit orders to our stocking locations.

        In certain circumstances, we also provide our JIT customers with additional value-added services, including the implementation of process control and usage reduction programs; support for environmental, health and safety compliance, or EHS, and reporting; and assistance with the development of waste management strategies.

    MRO Sales

        We sell products to airline-affiliated and independent maintenance, repair and overhaul, or MRO, providers on both a Contract and ad hoc basis. We have recently expanded our efforts to increase our presence in both the commercial and military aerospace MRO markets, particularly as a result of our acquisition of Interfast in 2012, our acquisition of Haas in 2014 and through the introduction of our Wesco e-commerce sales platform, which we believe provides us with a cost-effective way to further penetrate the MRO market. In addition, we have targeted domestic and international airlines and aircraft maintenance centers that we believe are assuming an expanded role within the MRO market.

        Going forward, we expect commercial MRO providers to benefit from the same trends as those impacting the commercial OEM market, including increased revenue passenger miles, which in turn should drive growth in the commercial fleet and greater utilization of existing aircraft. The commercial MRO market may also benefit from directives or notifications announced by international industry regulators and trade associations. Such directives or notifications can serve to bolster required maintenance, and thus the demand for new and existing aerospace products. We expect demand in the military MRO market to be driven by requirements to maintain aging military fleets, changes in the overall fleet size and the level of U.S. military activity overseas. We believe that our presence in this market helps us mitigate the volatility of new military aircraft sales with sales to the aftermarket.

Customer Contracts

        We sell products to our customers under two types of arrangements: (i) Contracts, which include JIT supply chain management contracts and LTAs, and (ii) ad hoc sales.

    Contracts

        JIT Contracts.    JIT contracts are typically three to five years in length and are structured to supply the product requirement for specific SKUs, production lines or facilities. Given our direct involvement with JIT customers, volume requirements and purchasing frequency under these contracts is highly predictable. Under JIT contracts, customers commit to purchase specified products from us at a fixed price or a pass-through price, on an if-and-when needed basis, and we are responsible for maintaining high levels of stock availability of those products. JIT contracts typically contain termination for convenience provisions, which generally allow our customers to terminate their contracts on short notice without meaningful penalties, provided that we are reimbursed for the cost of any inventory specifically procured for the customer. JIT customers often purchase products from us that are not covered under their contracts on an ad hoc basis. For additional information about our JIT supply chain management services, see "—Our Products and Services—Our Services—JIT Supply Chain Management."

Table of Contents

        LTAs.    Like JIT contracts, LTAs also typically run for three to five years. LTAs are essentially negotiated price lists for customers or individual customer sites that cover a range of pre-determined products, purchased on an as-needed basis. LTAs generally obligate the customer to buy contracted SKUs from us and may obligate us to maintain stock availability for those products. Once an LTA is in place, the customer is then able to place individual purchase orders with us for any of the contractually specified products. LTAs typically contain termination for convenience provisions, which generally allow for our customers to terminate their contracts on short notice without meaningful penalties, provided that we are reimbursed for the cost of any inventory specifically procured for the customer. LTA customers also frequently purchase products from us on an ad hoc basis that are not captured under the pricing arrangement.

    Ad Hoc Sales

        Ad hoc customers purchase products from us on an as-needed basis and are generally supplied out of our existing inventory. Typically, ad hoc orders are for smaller quantities of products than those ordered under Contracts, and are often urgent in nature. Given our breadth and volume of inventory, it is not uncommon for even our competitors to purchase products from us on an ad hoc basis when their own stocks prove to be inadequate. In an environment of increasing aircraft production, product shortages can become increasingly common for OEMs, subcontractors, MRO providers and distributors with less sophisticated forecasting abilities and procurement organizations.

        Under each of the sales arrangements described above we typically warrant that the products we sell conform to the drawings and specifications that are in effect at the time of delivery in the applicable Contract, and that we will replace defective or non-conforming products for a period of time that varies from Contract to Contract. The product manufacturer, in turn, typically indemnifies us for liabilities resulting from defective or non-conforming products. We do not accrue for warranty expenses as our claims related to defective and non-conforming products have been nominal.

        We believe that backlog is not a relevant measure of our business, given the long-term nature of our Contracts with our customers.

Customers

        We sell to over 8,300 active customers worldwide. During fiscal 2014, no single customer represented more than 8% of our net sales, and only 2 customers accounted for over 5% of our net sales, with each consisting of multiple independent programs. Our top 10 customers collectively accounted for 45% of our net sales during fiscal 2014.

        Approximately 80% of our fiscal 2014 net sales were derived from major OEMs, such as Airbus, Boeing, Bombardier, Embraer, Cessna, Gulfstream, BAE Systems, Bell Helicopter, Lockheed Martin, Northrop Grumman and Raytheon, and certain of their subcontractors. Government sales comprised roughly 9% of our net sales during fiscal 2014 and were derived from various military parts procurement agencies such as the U.S. Defense Logistics Agency, or from defense contractors buying on their behalf. Aftermarket sales to airline-affiliated or independent MRO providers made up roughly 6% of our fiscal 2014 net sales. The remaining 5% of our net sales are to other distributors on an ad hoc basis.

        During fiscal 2014, approximately 63% of our net sales were derived from customers supporting commercial programs and approximately 37% of our net sales were derived from customers supporting military programs. Our customers are principally located in the United States, with shipments to customers in the United States comprising approximately 57% of our net sales during fiscal 2014. We also service international customers in markets that include Australia, Canada, China, France, Germany, India, Ireland, Israel, Italy, Malaysia, Mexico, Philippines, Poland, Saudi Arabia, Singapore, South Korea, Turkey and the United Kingdom.

Procurement

        We source our inventory from over 6,200 suppliers, including Precision Castparts, Alcoa Fastening Systems, PPG, Monogram Aerospace Fasteners, Amphenol Corporation and Eaton Corporation. During fiscal 2014, Alcoa Fastening Systems and Precision Castparts each supplied approximately 15% of the products we purchased. Suppliers typically prefer to deal with a relatively small number of large and sophisticated distributors in order to improve machine utilization; reduce finished goods inventory and related obsolescence costs; maintain pricing discipline; improve performance in meeting on-time-delivery targets to end customers; and consolidate customer accounts, which can reduce administrative and overhead costs relating to sales and marketing, customer service and other functions. As a result of the scale of our operations and our long-standing relationships with many of our suppliers, we are often able to take advantage of significant volume-based discounts when purchasing inventory. Given our industry position, financial strength and philosophy of cooperation with suppliers, we believe we are in an excellent position to become a distributor for new product lines as they become available.

        We consider our procurement expertise to be one of our principal competitive advantages. Our management is highly skilled in analyzing supply, demand, cost and pricing factors to make optimal inventory investment decisions, which decisions are facilitated by our highly customized IT systems, and we maintain close relationships with the leading suppliers in the industry. Our strong understanding of the global aerospace industry is derived from our long-term relationships with major OEMs, subcontractors and suppliers. In addition, our direct insight into our customers' production rates often allows us to detect industry trends. Furthermore, our ability to forecast demand and place purchase orders with our suppliers well in advance of our customer requirements provides us with a distinct advantage in an industry where inventory availability is critical for customers that need specific products within a stipulated timeframe to meet their own production and delivery commitments. For additional information about the impact of inventory on our cash flows, see Part II, Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations—Executive Overview—Other Factors Affecting Our Financial Results—Fluctuations in Cash Flow".

Information Technology Systems

        We have invested to build integrated, highly customized IT systems that enable our purchasing and sales organization to make more informed decisions, our inventory management system to operate in an efficient manner and certain of our customers to make online purchases directly from us. Our primary scalable IT infrastructure is based on IBM servers and the Oracle JD Edwards EnterpriseOne, or JDE, enterprise resource planning, or ERP, system. In connection with the Haas acquisition, we also began utilizing tcmIS, which is Haas' proprietary IT system. These customized IT systems provide us visibility into inventory quantities, stocking locations and purchases across our customer base by individual SKU, enabling us to accurately fill approximately 12,000 orders per day (exclusive of the Haas business), and provide an exceptional level of customer service. The acquired Haas business provided approximately an additional 1,400 orders shipped per day during the period from March 1, 2014 to September 30, 2014. These systems are fully capable of interfacing with external business systems, including Oracle, SAP, Microsoft and others, and we have developed additional functionality for JIT delivery and direct line feed of certain of the products we sell. This functionality includes recognition of signals and actions to fill customer bins from hand-held scanners, min/max data or proprietary signals from a customer's ERP system. JDE and tcmIS also support our EDI functionality, which allows our system to interface with customers and suppliers, regardless of technology, data

format or connectivity. tcmIS also supports additional chemical-specific functionality, such as product labeling and EHS compliance.

        For our shipping logistics and export compliance support, we employ Precision Software's TRA/X. TRA/X enables us to ship globally while maintaining tracking numbers and rating information for each customer shipment. In addition, at several of our distribution facilities, we use Minerva's AIMS inventory management system in order to provide the best possible warehouse flow and cycle times. AIMS is tailored to fit our global warehouse operational needs and allows us to provide an expandable warehouse management system that can also incorporate transaction processing, work-in-progress and other manufacturing operations. AIMS interfaces with a broad range of material handling equipment, including horizontal and vertical carousels, conveyors, sorting equipment, pick systems and cranes.

Competition

        The industry in which we operate is highly competitive and fragmented. We believe the principal competitive factors in our industry include the ability to provide superior customer service and support, on-time delivery, sufficient inventory availability, competitive pricing and an effective QA program. Our competitors include both U.S. and foreign companies, including divisions of larger companies and certain of our suppliers, some of which have significantly greater financial resources than we do, and therefore may be able to adapt more quickly to changes in customer requirements than we can. In addition to facing competition for Contract customers from our primary competitors, Contract customers or potential Contract customers may also determine that it is more cost effective to establish or re-establish an in-house supply chain management system. Under these circumstances, we may be unable to sufficiently reduce our costs in order to provide competitive pricing while also maintaining acceptable operating margins.

Employees

        As of September 30, 2014, we employed 2,785 personnel worldwide, 556 of which were located at customer sites. We have 665 employees located outside of North America. We are not a party to any collective bargaining agreements with our employees.

Regulatory Matters

        Governmental agencies throughout the world, including the U.S. Federal Aviation Administration, or the FAA, prescribe standards for aircraft components, including virtually all commercial airline and general aviation products, as well as regulations regarding the repair and overhaul of airframes and engines. Specific regulations vary from country to country, although compliance with FAA requirements generally satisfies regulatory requirements in other countries. In addition, the products we distribute must also be certified by aircraft and engine OEMs. If any of the material authorizations or approvals that allow us to supply products is revoked or suspended, then the sale of the related products would be prohibited by law, which would have an adverse effect on our business, financial condition and results of operations.

        From time to time, the FAA or equivalent regulatory agencies in other countries propose new regulations or changes to existing regulations, which are usually more stringent than existing regulations. If these proposed regulations are adopted and enacted, we could incur significant additional costs to achieve compliance, which could have a material adverse effect on our business, financial condition and results of operations.

        We are also subject to government rules and regulations that include the U.S. Foreign Corrupt Practices Act, or FCPA, the International Traffic in Arms Regulations, or ITAR, and the False Claims Act. See "Risk Factors—We are subject to unique business risks as a result of supplying equipment and services directly and as a subcontractor, which could lead to a reduction in our net sales from, or the

profitability of our supply agreements with the U.S. Government" and "—Our international operations require us to comply with anti-corruption laws and regulations of the U.S. government and various international jurisdictions, and our failure to comply with these laws and regulations could adversely affect our reputation, business, financial condition and results of operations."

Environmental Matters

        We are subject to extensive federal, state, local and foreign laws, regulations, rules and ordinances relating to pollution, protection of the environment and human health and safety, and the handling, transportation, storage, treatment, disposal and remediation of hazardous substances, including potentially with respect to historical chemical blending and other activities that pre-dated our purchase of Haas. Actual or alleged violations of EHS laws, or permit requirements could result in restrictions or prohibitions on operations and substantial civil or criminal sanctions, as well as, under some EHS laws, the assessment of strict liability and/or joint and several liability.

        Furthermore, we may be liable for the costs of investigating and cleaning up environmental contamination on or from our operations or at off-site locations, including potentially with respect to historical chemical blending and other activities that pre-dated our purchase of our businesses. We may therefore incur additional costs and expenditures beyond those currently anticipated to address all such known and unknown situations under existing and future EHS laws.

        In addition, governmental, regulatory and societal demands for increasing levels of product safety and environmental protection could result in increased pressure for more stringent regulatory control with respect to the chemical industry. Changes in the Company's regulatory environment, particularly, but not limited to, in the United States, the European Union, Canada and China, could lead to heightened regulatory scrutiny and could adversely impact our ability to supply certain products and/to provide chemical management services to our customers. For instance, the European Union's Registration, Authorization and Restriction of Chemicals ("REACH" and analogous non-E.U. laws and regulations), or other similar laws and regulations, could result in compliance obligations, fines, ongoing monitoring and other future business activity restrictions, which could have a material adverse effect on the Company's liquidity, financial position and results of operations.

ITEM 1A.    RISK FACTORS

        You should consider and read carefully all of the risks and uncertainties described below, as well as other information included in this Annual Report, including our consolidated financial statements and related notes. The risks described below are not the only ones facing us. The occurrence of any of the following risks or additional risks and uncertainties not presently known to us or that we currently believe to be immaterial could materially and adversely affect our business, financial condition or results of operations. This Annual Report also contains forward-looking statements and estimates that involve risks and uncertainties. Our actual results could differ materially from those anticipated in the forward-looking statements as a result of specific factors, including the risks and uncertainties described below.

Risks Related to Our Business and Industry

We are directly dependent upon the condition of the aerospace industry, which is closely tied to global economic conditions, and if the volatility in the global financial markets were to result in a slowdown in the current economic recovery or a return to a recession, our business, financial condition and results of operations could be negatively impacted.

        Demand for the products and services we offer are directly tied to the delivery of new aircraft, aircraft utilization, and repair of existing aircraft, which, in turn, are impacted by global economic conditions. For example 2009, revenue passenger miles, or RPMs, on commercial aircraft declined due to the global recession. During the same period, the industry experienced declines in large commercial, regional and business jet deliveries. While demand for commercial and regional jets has fully recovered, business jet orders and deliveries have recovered more slowly. A slowdown in the current economic recovery, or a return to a recession, would negatively impact the aerospace industry, and could negatively impact our business, financial condition and results of operations.

Military spending, including spending on the products we sell, is dependent upon national defense budgets, and a reduction in military spending could have a material adverse effect on our business, financial condition and results of operations.

        During the year ended September 30, 2014, approximately 37% of our net sales were related to military aircraft. The military market is significantly dependent upon government budget trends, particularly the U.S. Department of Defense, or DoD, budget. Future DoD budgets could be negatively impacted by several factors, including, but not limited to, a change in defense spending policy by the current and future presidential administrations and Congress, the U.S. Government's budget deficits, spending priorities, the cost of sustaining the U.S. military presence in overseas operations and possible political pressure to reduce U.S. Government military spending, each of which could cause the DoD budget to decline. A decline in U.S. military expenditures could result in a reduction in military aircraft production, which could have a material adverse effect on our business, financial condition and results of operations.

        In particular, military spending may be negatively impacted by the Budget Control Act of 2011, or the Budget Control Act, which was passed in August 2011. The Budget Control Act established limits on U.S. government discretionary spending, including a reduction of defense spending by approximately $490 billion between the 2012 and 2021 U.S. government fiscal years, and also provided that the defense budget would face "sequestration" cuts of up to an additional $500 billion during that same period to the extent that discretionary spending limits were exceeded. The impact of sequestration was reduced with respect to the government's 2014 and 2015 fiscal years, in exchange for extending sequestration into fiscal years 2022 and 2023, following the enactment of the Bipartisan Budget Act of 2013 on December 26, 2013. Sequestration is currently scheduled to resume in the government's 2016 fiscal year. We are unable to predict the impact the cuts associated with Sequestration will ultimately have on funding for the military programs which we support. However, such cuts could result in

13


Table of Contents

reductions, delays or cancellations of these programs, which could have a material adverse effect on our business, financial condition and results of operations.

We are subject to unique business risks as a result of supplying equipment and services to the U.S. Government directly and as a subcontractor, which could lead to a reduction in our net sales from, or the profitability of our supply arrangements with, the U.S. Government.

        Companies engaged in supplying defense-related equipment and services to U.S. Government agencies are subject to business risks specific to the defense industry. We contract directly with the U.S. Government and are also a subcontractor to customers contracting with the U.S. Government. Accordingly, the U.S. Government may unilaterally suspend or prohibit us from receiving new contracts pending resolution of alleged violations of procurement laws or regulations, reduce the value of existing contracts or audit our contract- related costs and fees. In addition, most of our U.S. Government contracts and subcontracts can be terminated by the U.S. Government or the contracting party, as applicable, at its convenience. Termination for convenience provisions provide only for our recovery of costs incurred or committed, settlement expenses and profit on the work completed prior to termination.

        In addition, we are subject to U.S. government inquiries and investigations, including periodic audits of costs that we determine are reimbursable under government contracts. U.S. government agencies routinely audit government contractors to review performance under contracts, cost structure and compliance with applicable laws, regulations, and standards, as well as the adequacy of and compliance with internal control systems and policies. Any costs found to be misclassified or inaccurately allocated to a specific contract are not reimbursable, and to the extent already reimbursed, must be refunded. Also, any inadequacies in our systems and policies could result in payments being withheld, penalties and reduced future business.

        We are also subject to the federal False Claims Act, which provides for substantial civil penalties and treble damages where a contractor presents a false or fraudulent claim to the government for payment. Actions under the False Claims Act may be brought by the government or by other persons on behalf of the government (who may then share in any recovery).

We do not have guaranteed future sales of the products we sell and when we enter into Contracts with our customers we generally take the risk of cost overruns, and our business, financial condition, results of operations and operating margins may be negatively affected if we purchase more products than our customers require, product costs increase unexpectedly, we experience high start-up costs on new Contracts or our Contracts are terminated.

        A majority of our Contracts are long-term, fixed-price agreements with no guarantee of future sales volumes, and they may be terminated for convenience on short notice by our customers, often without meaningful penalties, provided that we are reimbursed for the cost of any inventory specifically procured for the customer. In addition, we purchase inventory based on our forecasts of anticipated future customer demand. As a result, we may take the risk of having excess inventory in the event that our customers do not place orders consistent with our forecasts, particularly with respect to inventory that has a more limited shelf-life. We also run the risk of not being able to pass along or otherwise recover unexpected increases in our product costs, including as a result of commodity price increases, which may increase above our established prices at the time we entered into the Contract and established prices for products we provide. When we are awarded new Contracts, particularly JIT contracts, we may incur high costs, including salary and overtime costs to hire and train on-site personnel, in the start-up phase of our performance. In the event that we purchase more products than our customers require, product costs increase unexpectedly, we experience high start-up costs on new Contracts or our Contracts are terminated, our business, financial condition, results of operations and operating margins could be negatively affected.

Table of Contents

If we lose significant customers, significant customers materially reduce their purchase orders or significant programs on which we rely are delayed, scaled back or eliminated, our business, financial condition and results of operations may be adversely affected.

        Our top ten customers for the year ended September 30, 2014 accounted for approximately 45% of our net sales. During fiscal years 2014, 2013 and 2012 no individual customer accounted for more than 10% of our net sales. A reduction in purchasing by or loss of one of our larger customers for any reason, such as changes in manufacturing or procurement practices, loss of a customer as a result of the acquisition of such customer by a purchaser who does not fully utilize a distribution model or uses a competitor, in-sourcing by customers, a transfer of business to a competitor, an economic downturn, failure to adequately service our clients, decreased production or a strike, could have a material adverse effect on our business, financial condition and results of operations.

        As an example of changes in manufacturing practices that could impact us, OEMs such as Boeing and Airbus are currently incorporating an increasing amount of composite materials in the aircraft they manufacture. Aircraft utilizing composite materials generally require the use of significantly fewer C class aerospace parts than new aircraft made of more traditional non-composite materials, although the parts used are generally higher priced than C class aerospace parts used in non-composite aircraft structures. As Boeing, Airbus and other customers increase their reliance on composite materials, they may materially reduce their purchase orders from us.

        As an example of the potential loss of business due to customer in-sourcing, it is our understanding that Boeing is undertaking an initiative to cause its first and second tier suppliers to source certain Boeing-specific materials, including fasteners, directly from Boeing, rather than through distributors such as us. If Boeing's initiative is broadly implemented, a portion of our sales to these Boeing suppliers, and consequently our business, financial condition and results of operations, could be adversely affected.

        While we believe that we have a diversified customer and aircraft program base, we expect to derive a significant portion of our net sales from certain aerospace programs in their early production stages. In particular, our future growth will be dependent, in part, upon our sales to various OEMs and subcontractors related to the Boeing 787 and the Lockheed Martin Joint Strike Fighter, or JSF. If production of any of the programs we support is terminated or delayed, or if our sales to customers affiliated with these programs are reduced or eliminated, our business, financial condition and results of operations could be adversely affected. For example, the Boeing 787 program was grounded by a Federal Aviation Administration order in 2013 as a result of battery related issues. If additional safety risks or other quality concerns were to result slowed or suspended production of the 787 program in the future, it could have an adverse effect on our future earnings and result in a potential write-off of inventory currently on hand.

        In addition, during fiscal year 2014, we modified and extended a contract with an existing customer that may result in up to a $50 million reduction in net sales to the customer during fiscal year 2015 compared to fiscal year 2014

We operate in a highly competitive market and our failure to compete effectively may negatively impact our results of operations.

        We operate in a highly competitive global industry and compete against a number of companies, including divisions of larger companies and certain of our suppliers, some of which may have significantly greater financial resources than we do, and therefore may be able to adapt more quickly to changes in customer requirements than we can. Our competitors consist of both U.S. and foreign companies and range in size from divisions of large public corporations to small privately held entities. We believe that our ability to compete depends on superior customer service and support, on-time delivery, sufficient inventory availability, competitive pricing and effective quality assurance programs.

15


Table of Contents

In order to remain competitive, we may have to adjust the prices of some of the products and services we sell and continue investing in our procurement, supply-chain management and sales and marketing functions, the costs of which could negatively impact our results of operations.

        In addition, we face competition for our Contract customers from both competitors in our industry and the in-sourcing of supply-chain management by our customers themselves. If any of our Contract customers decides to in-source the services we provide or switch to one of our competitors, we would be adversely affected.

We may be unable to effectively manage our inventory as we grow, which could have a material adverse effect on our business, financial condition and results of operations.

        We have experienced rapid growth in recent periods and intend to continue to grow our business by increasing our product offerings and expanding our customer base. Due to the lead times required by many of our suppliers, we typically order products in advance of expected sales, and the volume of such orders may be significant as a result of our growth strategy. Lead times generally range from several weeks up to two years, depending on industry conditions, which make it difficult to successfully manage our inventory as we plan for expected growth. For example, we believe that the strategic inventory purchases we made during fiscal 2013 and 2014, combined with lower than expected demand, negatively impacted our cash flows. In the future, if we are unable to effectively manage our inventory as we attempt to grow our business, our cash flows may be negatively affected, which could have a material adverse effect on our business, financial condition and results of operations.

If suppliers are unable to supply us with the products we sell in a timely manner, in adequate quantities and/or at a reasonable cost, we may be unable to meet the demands of our customers, which could have a material adverse effect on our business, financial condition and results of operations.

        Our inventory is primarily sourced directly from producers and manufacturing firms, and we depend on the availability of large supplies of the products we sell. Our largest supplier for the year ended September 30, 2014 was Precision Castparts. During fiscal 2014, approximately 15% of the products we purchased were from Precision Castparts and 15% were purchased from Alcoa Fastening Systems. In addition, our ten largest suppliers during fiscal 2014 accounted for approximately 43% of our purchases. These manufacturers and producers may experience capacity constraints that result in their being unable to supply us with products in a timely manner, in adequate quantities and/or at a reasonable cost. Contributing factors to manufacturer capacity constraints include, among other things, industry or customer demands in excess of machine capacity, labor shortages and changes in raw material flows. Any significant interruption in the supply of these products or termination of our relationship with any of our suppliers could result in us being unable to meet the demands of our customers, which would have a material adverse effect on our business, financial condition and results of operations.

Our business is highly dependent on complex information technology.

        The provision and application of IT is an increasingly critical aspect of our business. Among other things, our IT systems must frequently interact with those of our customers, suppliers and logistics providers. Our future success will depend on our continued ability to employ IT systems that meet our customers' demands. The failure or disruption of the hardware or software that supports our IT systems, including redundancy systems, could significantly harm our ability to service our customers and cause economic losses for which we could be held liable and which could damage our reputation.

        Our competitors may have or may develop IT systems that permit them to be more cost effective and otherwise better situated to meet customer demands than IT systems we are able to acquire or develop. Larger competitors may be able to develop or license IT systems more cost effectively than we

16


Table of Contents

can by spreading the cost across a larger revenue base, and competitors with greater financial resources may be able to acquire or develop IT systems that we cannot afford. If we fail to meet the demands of our customers or protect against disruptions of our IT systems, we may lose customers, which could seriously harm our business and adversely affect our operating results and operating cash flow.

We may be unable to retain personnel who are key to our operations.

        Our success, among other things, is dependent on our ability to attract, develop and retain highly qualified senior management and other key personnel. Competition for key personnel is intense, and our ability to attract and retain key personnel is dependent on a number of factors, including prevailing market conditions and compensation packages offered by companies competing for the same talent. The inability to hire, develop and retain these key employees may adversely affect our operations.

There are risks inherent in international operations that could have a material adverse effect on our business, financial condition and results of operations.

        While the majority of our operations are based in the United States, we have significant international operations, with facilities in Australia, Canada, China, France, Germany, India, Ireland, Israel, Italy, Malaysia, Mexico, Philippines, Poland, Saudi Arabia, Singapore, South Korea, Turkey and the United Kingdom, and customers throughout North America, Latin America, Europe, Asia and the Middle East. For the years ended September 30, 2014 and 2013, 43% and 42% of our net sales were derived from customers located outside the United States, respectively.

        Our international operations are subject to, without limitation, the following risks:

    the burden of complying with multiple and possibly conflicting laws and any unexpected changes in regulatory requirements;

    political risks, including risks of loss due to civil disturbances, acts of terrorism, acts of war, guerilla activities and insurrection;

    unstable economic, financial and market conditions and increased expenses as a result of inflation, or higher interest rates;

    difficulties in enforcement of third-party contractual obligations and collecting receivables through foreign legal systems;

    difficulties in staffing and managing international operations and the application of foreign labor regulations;

    differing local product preferences and product requirements; and

    potentially adverse tax consequences from changes in tax laws, requirements relating to withholding taxes on remittances and other payments by subsidiaries and restrictions on our ability to repatriate dividends from our subsidiaries.

        In addition, fluctuations in the value of foreign currencies affect the dollar value of our net investment in foreign subsidiaries, with these fluctuations being included in a separate component of stockholders' equity. At September 30, 2014, we reported a cumulative foreign currency translation adjustment of approximately $0.6 million in stockholders' equity as a result of foreign currency adjustments, and we may incur additional adjustments in future periods. In addition, operating results of foreign subsidiaries are translated into U.S. dollars for purposes of our statement of comprehensive income at average monthly exchange rates. Moreover, to the extent that our net sales are not denominated in the same currency as our expenses, our net earnings could be materially adversely affected. For example, a portion of labor, material and overhead costs for our facilities in the United Kingdom, Germany, France and Italy are incurred in British Pounds or Euros, but in certain cases the

17


Table of Contents

related net sales are denominated in U.S. dollars. Changes in the value of the U.S. dollar or other currencies could result in material fluctuations in foreign currency translation amounts or the U.S. dollar value of transactions and, as a result, our net earnings could be materially adversely affected. Although we at times engage in hedging transactions to manage or reduce our foreign exchange risk, our attempts to manage our foreign currency exchange risk may not be successful and, as a result, our business, financial condition and results of operations could be materially adversely affected. During fiscal 2012 and 2013, the strengthening of the U.S. dollar relative to the British pound resulted in a negative impact on net sales of approximately $2.1 million and $1.5 million, respectively. During fiscal 2014, the U.S. dollar weakened slightly against the pound, resulting a positive impact on net sales of approximately $15.5 million. Our international operations also cause our business to be subject to the U.S. Export Control regime and similar regulations in other countries, in particular in the United Kingdom. In the United States, items of a commercial nature are generally subject to regulatory control by the U.S. Department of Commerce's Bureau of Industry and Security and to Export Administration Regulations, and other international trade regulations may apply as well. Additionally, we are not permitted to export some of the products we sell. In the future, regulatory authorities may require us to obtain export licenses or other export authorizations to export the products we sell abroad, depending upon the nature of items being exported, as well as the country to which the export is to be made. We cannot assure you that any of our applications for export licenses or other authorizations will be granted or approved. Furthermore, the export license and export authorization process is often time-consuming. Violation of export control regulations could subject us to fines and other penalties, such as losing the ability to export for a period of years, which would limit our sales and significantly hinder our attempts to expand our business internationally.

Our international operations require us to comply with anti-corruption and trade control laws and regulations of the U.S. government and various international jurisdictions, and our failure to comply with these laws and regulations could adversely affect our reputation, business, financial condition and results of operations.

        Doing business on a worldwide basis requires us and our subsidiaries to comply with the laws and regulations of the U.S. government and various international jurisdictions, and our failure to successfully comply with these rules and regulations may expose us to liabilities. These laws and regulations apply to companies, individual directors, officers, employees and agents, and may restrict our operations, trade practices, investment decisions and partnering activities.

        In particular, our international operations are subject to U.S. and foreign anti-corruption laws and regulations, such as the U.S. Foreign Corrupt Practices Act, or FCPA, and, in some cases, the UK Bribery Act 2010, or Bribery Act. These laws generally prohibit us from corruptly providing anything of value, directly or indirectly, to government officials for the purposes of improperly influencing official decisions or improperly obtaining or retaining business or otherwise obtaining favorable treatment. Some laws, such as the Bribery Act, also prohibit commercial bribery and the acceptance of bribes, and the FCPA further requires publicly traded companies to maintain adequate record-keeping and internal accounting practices to accurately reflect the transactions of the Company. As part of our business, we may deal with governments and state-owned business enterprises, the employees and representatives of which may be considered government officials for purposes of the FCPA, the Bribery Act or other applicable anti-corruption laws. In addition, some of the international locations in which we operate lack a developed legal system and have elevated levels of corruption. As a result of the above activities, we are exposed to the risk of violating anti-corruption laws.

        As an exporter, we must comply with various laws and regulations relating to the export of products, services and technology from the United States and other countries having jurisdiction over our operations. In the U.S., these laws include, among others, the U.S. Export Administration Regulations (EAR) administered by the U.S. Department of Commerce, Bureau of Industry and Security, the International Traffic in Arms Regulations (ITAR) administered by the U.S. Department of

18


Table of Contents

State, Directorate of Defense Trade Controls (DDTC), and trade sanctions, regulations and embargoes administered by the U.S. Department of the Treasury, Office of Foreign Assets Control. These laws and regulations may require us to obtain individual validated licenses from the relevant agency to export, re-export, or transfer commodities, software, technology, or services to certain jurisdictions.

        Violations of these legal requirements are punishable by criminal fines and imprisonment, civil penalties, disgorgement of profits, injunctions, debarment from government contracts, seizure and forfeiture of unlawful attempted exports, and/or denial of export privileges, as well as other remedial measures. We have established policies and procedures designed to assist us and our personnel to comply with applicable U.S. and international laws and regulations. However, there can be no assurance that our policies and procedures will effectively prevent us from violating these regulations in every transaction in which we may engage, and such a violation could adversely affect our reputation, business, financial condition and results of operations.

If any of our customers were to become insolvent or experience substantial financial difficulties, our business, financial condition and results of operations may be adversely affected.

        If any of the customers with whom we do business becomes insolvent or experiences substantial financial difficulties we may be unable to timely collect amounts owed to us by such customers and may not be able to sell the inventory we have purchased for such customers, which could have a material adverse effect on our business, financial condition and results of operations.

Our suppliers or our customers may experience damage to or disruptions at our or their facilities caused by natural disasters and other factors, which may result in our business, financial condition and results of operations being adversely affected.

        Several of our facilities or those of our suppliers and customers could be subject to a catastrophic loss caused by earthquakes, tornadoes, floods, hurricanes, fire, power loss, telecommunication and information systems failure or other similar events. Should insurance be insufficient to recover all such losses or should we be unable to reestablish our operations, or if our customers or suppliers were to experience material disruptions in their operations as a result of such events, our business, financial condition and results of operations could be adversely affected.

We are dependent on access to and the performance of third-party package delivery companies.

        Our ability to provide efficient distribution of the products we sell to our customers is an integral component of our overall business strategy. We do not maintain our own delivery networks, and instead rely on third-party package delivery companies. We cannot assure you that we will always be able to ensure access to preferred delivery companies or that these companies will continue to meet our needs or provide reasonable pricing terms. In addition, if the package delivery companies on which we rely experience delays resulting from inclement weather or other disruptions, we may be unable to maintain products in inventory and deliver products to our customers on a timely basis, which may adversely affect our business, financial condition and results of operations.

A significant labor dispute involving us or one or more of our customers or suppliers, or a labor dispute that otherwise affects our operations, could reduce our net sales and harm our profitability.

        Labor disputes involving us or one or more of our customers or suppliers could affect our operations. If our customers or suppliers are unable to negotiate new labor agreements and our customers' or suppliers' plants experience slowdowns or closures as a result, our net sales and profitability could be negatively impacted.

        While our employees are not currently unionized, they may attempt to form unions in the future, and the employees of our customers, suppliers and other service providers may be, or may in the future be, unionized. We cannot assure you that there will not be any strike, lock out or material labor dispute with respect to our business or those of our customers or suppliers in the future that materially affects our business, financial condition and results of operations.

We may be materially adversely affected by high fuel prices.

        Fluctuations in the global supply of crude oil and the possibility of changes in government policies on the production, transportation and marketing of jet fuel make it impossible to predict the future availability and price of jet fuel. In the event there is an outbreak or escalation of hostilities or other conflicts or significant disruptions in oil production or delivery in oil-producing areas or elsewhere, there could be reductions in the production or importation of crude oil and significant increases in the cost of jet fuel. If there were major reductions in the availability of jet fuel or significant increases in its cost, commercial airlines would face increased operating costs. Due to the competitive nature of the airline industry, airlines are often unable to pass on increases in fuel prices to customers by increasing fares. As a result, an increase in jet fuel could result in a decrease in net income from either lower margins or, if airlines increase ticket fares, lower net sales from reduced airline travel. Decreases in airline profitability could decrease the demand for new commercial aircraft, resulting in delays of or reductions in deliveries of commercial aircraft that utilize the products we sell, and, as a result, our business, financial condition and results of operations could be materially adversely affected.

Our financial results may fluctuate from period-to-period, making quarter-to-quarter comparisons of our business, financial condition and results of operations less reliable indicators of our future performance.

        There are many factors, such as the cyclical nature of the aerospace industry, fluctuations in our ad hoc sales, delays in major aircraft programs, downward pressure on sales prices and changes in the volume of our customers' orders that could cause our financial results to fluctuate from period-to-period. For example, during the year ended September 30, 2014, approximately 28% of our net sales were derived from ad hoc sales. The prices we charge for ad hoc sales are typically higher than the prices under our Contract sales. However, ad hoc customers may not continue to purchase the same amount of products from us as they have in the past, so we cannot assure you that in any given year we will be able to generate similar net sales from our ad hoc customers as we did in the past. We are also actively working to transition customers from ad hoc purchases to Contracts, which may also result in a reduction in ad hoc purchases. In addition, our acquisition of Haas is expected to continue to lower our ad hoc sales as a percentage of net sales. A significant diminution in our ad hoc sales in any given period could result in fluctuations in our financial results and operating margins. As a result of these factors, we believe that quarter-to-quarter comparisons of our financial results are not necessarily meaningful and that these comparisons cannot be relied upon as indicators of future performance.

We will continue to incur a significant increase in costs as a result of operating as a publicly traded company, and our management will be required to devote substantial time to new compliance requirements and investor needs.

        As a publicly traded company, we will continue to incur significant legal, accounting and other expenses. In addition, the Sarbanes-Oxley Act of 2002, or the Sarbanes-Oxley Act, and the rules of the Securities and Exchange Commission, or the SEC, and the New York Stock Exchange have imposed various requirements on public companies. Our management and other personnel will continue to devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations will continue to result in increased legal and financial compliance costs and make some activities more time-consuming and costly. For example, we believe these rules and regulations make it

more difficult and more expensive for us to maintain appropriate levels of director and officer liability insurance.

We have identified a material weakness in our internal control over financial reporting which could result in a material misstatement to our annual or interim consolidated financial statements that would not be prevented or detected.

        In connection with the audit of our consolidated financial statements as of and for the year ended September 30, 2014, we have concluded that there is a material weakness relating to our internal control over financial reporting. The material weakness we identified relates to a lack of a sufficient complement of accounting and financial reporting personnel with an appropriate level of accounting knowledge and experience commensurate with our financial reporting requirements as of September 30, 2014. We have concluded this material weakness was a direct result of the heightened level of activity associated with the integration of the Haas acquisition, combined with the loss of one senior accounting employee due to attrition and the absence of another key accounting employee due to an illness, both of which impacted the execution of our controls during the fourth quarter of fiscal 2014.

        A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company's annual or interim financial statements will not be prevented or detected on a timely basis. As a result of this material weakness, management has concluded that our internal control over financial reporting and disclosure controls and procedures were not effective as of September 30, 2014.

        As described in "Part II—Item 9A—Controls and Procedures" we have begun, and are currently in the process of, remediating the material weakness. However, the measures we have taken and expect to take to improve our internal controls may not be sufficient to address the issue, and we may need to take additional measures to ensure that our internal controls are effective or to ensure that the identified material weakness will not result in a material misstatement of our annual or interim consolidated financial statements.

        If we fail to establish and maintain adequate internal control over financial reporting, including any failure to implement remediation measures and enhancements for internal controls, or if we experience difficulties in their implementation, our business, financial condition and operating results could be harmed. Further, any material weakness or unsuccessful remediation could affect investor confidence in the accuracy and completeness of our financial statements. As a result, our ability to obtain additional financing on favorable terms or at all could be materially and adversely affected, which in turn could materially and adversely affect our business, our strategic alternatives, our financial condition and the market value of our securities. In addition, perceptions of us among customers, lenders, investors, securities analysts and others could also be adversely affected.

        We can give no assurances that the measures we have taken to date, or any future measures we may take, will remediate the material weaknesses identified or that any additional material weaknesses will not arise in the future. In addition, even if we are successful in strengthening our controls and procedures, those controls and procedures may not be adequate to prevent or identify irregularities or ensure the fair and accurate presentation of our financial statements included in our periodic reports filed with the SEC.

We are subject to health, safety and environmental laws and regulations, any violation of which could subject us to significant liabilities and penalties.

        We are subject to extensive federal, state, local and foreign laws, regulations, rules and ordinances relating to pollution, protection of the environment and human health and safety, and the handling, transportation, storage, treatment, disposal and remediation of hazardous substances, including potentially with respect to historical chemical blending and other activities that pre-dated the purchase

of the Haas business by Wesco. Actual or alleged violations of EHS laws, or permit requirements could result in restrictions or prohibitions on operations and substantial civil or criminal sanctions, as well as, under some EHS laws, the assessment of strict liability and/or joint and several liability.

        Furthermore, we may be liable for the costs of investigating and cleaning up environmental contamination on or from our operations or at off-site locations, including potentially with respect to historical chemical blending and other activities that pre-dated the purchase of the Haas business by Wesco. We may therefore incur additional costs and expenditures beyond those currently anticipated to address all such known and unknown situations under existing and future EHS laws.

        Governmental, regulatory and societal demands for increasing levels of product safety and environmental protection could result in increased pressure for more stringent regulatory control with respect to the chemical industry. Changes in the Company's regulatory environment, particularly, but not limited to, in the United States, the European Union, Canada and China, could lead to heightened regulatory scrutiny and could adversely impact our ability to supply certain products to and provide supply chain management services to our customers. For instance, the European Union's Registration, Authorization and Restriction of Chemicals and analogous non-European Union laws and regulations, or other similar laws and regulations, could result in compliance obligations, fines, ongoing monitoring and other future business activity restrictions, which could have a material adverse effect on our business, financial condition and results of operations.

        In addition, these concerns could influence public perceptions regarding our operations and our ability to attract and retain customers and employees. Moreover, changes in EHS regulations could inhibit or interrupt our operations, or require us to modify our facilities or operations. Accordingly, environmental or regulatory matters may cause us to incur significant unanticipated losses, costs, capital expenditures or liabilities, which could reduce our profitability. Such losses, costs, capital expenditures or liabilities will be subject to evolving regulatory requirements and will depend on the timing of the promulgation and enforcement of specific standards which impose requirements on our operations. As a result, these losses, costs, capital expenditures or liabilities may be more than currently anticipated.

Our operations involve risks associated with the handling, transportation, storage and disposal of chemical products that may increase our operating costs and reduce our profitability.

        Although we take precautions to enhance the safety of our own operations as well as the safety of our customers' operations when we are supplying chemicals and/or providing related supply chain management services, our business is subject to hazards inherent in the handling, transportation, storage and disposal of chemical products. These hazards include: chemical spills, storage tank leaks, discharges or releases of toxic or hazardous substances or gases and other hazards incident to the handling, transportation, storage and disposal of dangerous chemicals. We are also potentially subject to other hazards, including natural disasters and severe weather; explosions and fires; transportation problems, including interruptions, spills and leaks; mechanical failures; unscheduled downtimes; labor difficulties; and other risks. Many potential hazards can cause bodily injury and loss of life, severe damage to or destruction of property and equipment and environmental damage, and may result in suspension of our own or our customers' operations and the imposition of civil or criminal penalties and liabilities. Furthermore, we are subject to present and future claims with respect to our employees when working within our own operations or when supplying chemicals to and/or providing chemical management services at our customer's operations, other persons, including potentially our customers and their employees, workers' compensation and other matters.

        We maintain property, business interruption, products liability and casualty insurance policies which we believe are in accordance with customary industry practices, as well as insurance policies covering other types of risks, including pollution legal liability insurance, but we are not fully insured against all potential hazards and risks incident to our business. Each of these insurance policies is subject to customary exclusions, deductibles and coverage limits, in accordance with industry standards

22


Table of Contents

and practices. As a result of market conditions, premiums and deductibles for certain insurance policies can increase substantially and, in some instances, certain insurance may become unavailable or available only for reduced amounts of coverage. If we were to incur a significant liability for which we were not fully insured, it could have a material adverse effect on our business, results of operations, financial condition and liquidity.

If the temperature control systems on which we rely fail, certain of the chemical products we sell may become "non-conforming" while in storage or in transit, and as a result, we may be responsible for providing replacement products to our customers, which could have a material adverse effect on our business, financial condition and results of operations.

        Many of the chemical products we sell are sensitive to temperature. Our storage facilities and the vehicles maintained by the third-party delivery companies on whom we rely utilize sophisticated temperature control systems to ensure safe storage and handling of these products. If these temperature control systems fail, products that are sensitive to temperature may become non-conforming to the customer's specifications, and we may be responsible for providing replacement products, which could have a material adverse effect on our business, financial condition and results of operations.

Our reputation and/or our business, financial condition and results of operations could be adversely affected if one of the products we sell causes an aircraft to crash.

        We may be exposed to liabilities for personal injury, death or property damage as a result of the failure of a product we have sold. We typically agree to indemnify our customers against certain liabilities resulting from the products we sell. Although we may seek third-party indemnification from our suppliers in the event of a product failure, we cannot guarantee that we will be successful in doing so and may ultimately be held liable. While we maintain liability insurance to protect us in these situations, our insurers may attempt to deny coverage or any coverage we have may not be adequate. We also may not be able to maintain insurance coverage in the future at an acceptable cost. Any liability for which third-party indemnification is not available that is not covered by insurance could have a material adverse effect on our business, financial condition and results of operations.

        In addition, a crash caused by one of the products we have sold could damage our reputation for selling quality products. We believe our customers consider safety and reliability as key criteria in selecting a provider of aircraft products and believe our reputation for quality assurance is a significant competitive strength. If a crash were to be caused by one of the products we sold, or if we were to otherwise fail to maintain a satisfactory record of safety and reliability, our ability to retain and attract customers may be materially adversely affected.

We sell products to a highly regulated industry and our business may be adversely affected if our suppliers or customers lose government approvals, if more stringent government regulations are enacted or if industry oversight is increased.

        The aerospace industry is highly regulated in the United States and in other countries. The FAA prescribes standards and other requirements for aircraft components in the U.S. and comparable agencies, such as the European Aviation Safety Agency, the Civil Aviation Administration of China and the Japanese Civil Aviation Bureau, regulate these matters in other countries. Our suppliers and customers must generally be certified by the FAA, the DoD and similar agencies in foreign countries. If any of our suppliers' government certifications are revoked, we would be less likely to buy such supplier's products, and, as a result, would need to locate a suitable alternate supply of such products, which we may be unable to accomplish on commercially reasonable terms or at all. If any of our customers' government certifications are revoked, their demand for the products we sell would decline. In each case, our business, financial condition and results of operations may be adversely affected.

23


Table of Contents

        In addition, if new and more stringent government regulations are adopted or if industry oversight increases, our suppliers and customers may incur significant expenses to comply with such new regulations or heightened industry oversight. In the case of our suppliers, these expenses may be passed on to us in the form of price increases, which we may be unable to pass along to our customers. In the case of our customers, these expenses may limit their ability to purchase products from us. In each case, our business, financial condition and results of operations may be adversely affected.

We may not be able to successfully integrate Haas in a timely fashion or at all and may encounter significant unexpected difficulties in integrating the two businesses.

        On February 28, 2014, we completed the acquisition of Haas. Prior to the acquisition, Wesco and Haas were independent organizations, each utilizing different systems, controls, processes and procedures. Following completion of the acquisition of Haas, our ability to fully realize the anticipated benefits of the acquisition of Haas will depend, to a large extent, on our ability to integrate the Haas business. The combination of two independent enterprises is a complex, costly and time-consuming process. The overall integration may result in unanticipated problems, expenses, liabilities, loss of client relationships, expenditure of resources and distraction of management and personnel. The difficulties of combining the operations include:

    we may not realize any or all of the potential benefits of the acquisition of Haas that could result from combining the businesses of Wesco and Haas;

    the acquisition of Haas could have an adverse impact on our relationships with employees, customers and suppliers, and prospective customers or other third parties may delay or decline entering into agreements with us as a result of the acquisition;

    management's attention may be diverted to integration matters;

    we may devote significant resources to integration;

    we may not be able to achieve anticipated cost savings and synergies;

    we may have difficulties integrating financial accounting systems, internal controls and standards, procedures and policies (including with respect to Sarbanes-Oxley Act compliance);

    the assumptions both Wesco and Haas have made regarding critical accounting estimates could be incorrect; and

    integration of our IT systems.

We may be unable to successfully consummate or integrate future acquisitions, which could negatively impact our business, financial condition and results of operations.

        We may consider future acquisitions, some of which could be material to us. Depending upon the acquisition opportunities available, we may need to raise additional funds through the capital markets or arrange for additional debt financing in order to consummate such acquisitions. We may be unable to raise the capital required for future acquisitions on satisfactory terms or at all, which could adversely affect our business, financial condition and results of operations.

Our total assets include substantial intangible assets, and the write-off of a significant portion of our intangible assets would negatively affect our financial results.

        Our total assets reflect substantial intangible assets. At September 30, 2014, goodwill and intangible assets, net represented approximately 45% of our total assets. Goodwill represents the excess of the purchase price of acquired businesses over the fair value of the assets acquired and liabilities assumed resulting from acquisitions, including the acquisition by affiliates of The Carlyle Group, or Carlyle. Intangible assets represent trade names, customer backlogs, non-compete agreements and

24


Table of Contents

customer relationships. On at least an annual basis, we assess whether there has been impairment in the value of goodwill and indefinite-lived intangible assets. If our testing identifies impairment under generally accepted accounting principles in the United States, the impairment charge we calculate would result in a charge to operating earnings. Any determination requiring the write-off of a significant portion of goodwill and unamortized identified intangible assets would negatively affect our results of operations and total capitalization, which could be material.

Our substantial indebtedness could adversely affect our financial health and could harm our ability to react to changes to our business.

        As of September 30, 2014, our total long-term indebtedness outstanding under our senior secured credit facilities (as defined in Part II, Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Reserves—Credit Facilities—Senior Secured Credit Facilities") was approximately $1,102.7 million, which was approximately 52.5% of our total capitalization.

        In addition, we may incur substantial additional indebtedness in the future. Although the senior secured credit facilities contain restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of significant qualifications and exceptions, and the indebtedness incurred in compliance with these qualifications and exceptions could be substantial. If we incur additional debt, the risks associated with our substantial leverage would increase.

        Our substantial indebtedness could have important consequences to investors. For example, it could:

    increase our vulnerability to general economic downturns and industry conditions;

    require us to dedicate a substantial portion of our cash flow from operations to payments on our indebtedness, thereby reducing the availability of our cash flow to fund working capital, capital expenditures and other general corporate requirements;

    limit our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate;

    place us at a competitive disadvantage compared to competitors that have less debt; and

    limit, along with the financial and other restrictive covenants contained in the documents governing our indebtedness, among other things, our ability to borrow additional funds, make investments and incur liens.

        In addition, all of our debt under the senior secured credit facilities bears interest at floating rates. Accordingly, in the event that interest rates increase, our debt service expense will also increase.

        Our level of indebtedness increases the possibility that we may be unable to generate cash sufficient to pay, when due, the principal of, interest on or other amounts due in respect of our indebtedness. We cannot assure you that our business will generate sufficient cash flow from operations or that future borrowings will be available to us under the senior secured credit facilities or otherwise in amounts sufficient to enable us to service our indebtedness. If we cannot service our debt, we will have to take actions such as reducing or delaying capital investments, selling assets, restructuring or refinancing our debt or seeking additional equity capital and cannot assure you that we will be successful in implementing any such actions or that any actions we take will allow us to stay in compliance with the terms of our indebtedness.

25


Table of Contents

The terms of the senior secured credit facilities and other debt instruments may restrict our current and future operations, particularly our ability to respond to changes or to take certain actions.

        The senior secured credit facilities contain a number of restrictive covenants that impose significant operating and financial restrictions on us and may limit our ability to engage in acts that may be in our long-term best interests. The senior secured credit facilities include covenants restricting, among other things, our ability to:

    incur or guarantee additional indebtedness or issue preferred stock;

    pay distributions on, redeem or repurchase our capital stock or redeem or repurchase our subordinated debt;

    make investments;

    sell assets;

    enter into agreements that restrict distributions or other payments from our restricted subsidiaries to us;

    incur or allow existing liens;

    consolidate, merge or transfer all or substantially all of our assets;

    engage in transactions with affiliates;

    enter into sale leaseback transactions;

    change fiscal periods;

    enter into agreements that restrict the granting of liens or the making of subsidiary distributions;

    create unrestricted subsidiaries; and

    engage in certain business activities.

        In addition, the senior secured credit facilities contain financial maintenance covenants, including a maximum leverage ratio covenant and a minimum interest coverage ratio covenant. A breach of any of these covenants could result in a default under the senior secured credit facilities. If any such default occurs, the lenders under the senior secured credit facilities may elect to declare all outstanding borrowings, together with accrued interest and other amounts payable thereunder, to be immediately due and payable. The lenders under the senior secured credit facilities also have the right in these circumstances to terminate any commitments they have to provide further borrowings. In addition, following an event of default under the senior secured credit facilities, the lenders under those facilities will have the right to proceed against the collateral granted to them to secure the debt, which includes our available cash. If the debt under the senior secured credit facilities was to be accelerated, we cannot assure you that our assets would be sufficient to repay in full our debt.

Risks Related to our Common Stock

The price of our common stock may fluctuate significantly, and you could lose all or part of your investment.

        Volatility in the market price of our common stock may prevent you from being able to sell your common stock at or above the price you paid for your common stock. The market price of our common stock could fluctuate significantly for various reasons, including:

    our operating and financial performance and prospects;

    our quarterly or annual earnings or those of other companies in our industry;

    the public's reaction to our press releases, our other public announcements and our filings with the SEC;

26


Table of Contents

    changes in, or failure to meet, earnings estimates or recommendations by research analysts who track our common stock or the stock of other companies in our industry;

    the failure of analysts to cover our common stock;

    strategic actions by us or our competitors, such as acquisitions or restructurings;

    new laws or regulations or new interpretations of existing laws or regulations applicable to our business;

    changes in accounting standards, policies, guidance, interpretations or principles;

    the impact on our profitability temporarily caused by the time lag between when we experience cost increases until these increases flow through cost of sales because of our method of accounting for inventory;

    material litigation or government investigations;

    changes in general conditions in the United States and global economies or financial markets, including those resulting from war, incidents of terrorism or responses to such events;

    changes in key personnel;

    sales of common stock by us or members of our management team;

    the termination of lock-up agreements with our directors, officers and stockholders;

    the granting or exercise of employee stock options;

    the volume of trading in our common stock; and

    the realization of any risks described under "Risk Factors."

        In addition, in the past five years, the U.S. stock market has experienced significant price and volume fluctuations. This volatility has had a significant impact on the market price of securities issued by many companies, including companies in our industry. The changes frequently appear to occur without regard to the operating performance of the affected companies. Hence, the price of our common stock could fluctuate based upon factors that have little or nothing to do with our Company, and these fluctuations could materially reduce our share price and cause you to lose all or part of your investment. Further, in the past, market fluctuations and price declines in a company's stock have led to securities class action litigations. If such a suit were to arise, it could have a substantial cost and divert our resources regardless of the outcome.

If securities analysts do not publish research or reports about our business or if they downgrade our stock, the price of our stock could decline.

        The research and reports that industry or financial analysts publish about us or our business may vary widely and may not predict accurate results, but will likely have an effect on the trading price of our common stock. If an industry analyst decides not to cover our Company, or if an industry analyst decides to cease covering our Company at some point in the future, we could lose visibility in the market, which in turn could cause our stock price to decline. If an industry analyst downgrades our stock, our stock price would likely decline rapidly in response.

We have no plans to pay regular dividends on our common stock, so you may not receive funds without selling your common stock.

        We have no plans to pay regular dividends on our common stock. We generally intend to invest our future earnings, if any, to fund our growth. Any payment of future dividends will be at the discretion of our board of directors and will depend on, among other things, our earnings, financial condition, capital requirements, level of indebtedness, statutory and contractual restrictions applying to

27


Table of Contents

the payment of dividends and other considerations that our board of directors deems relevant. The senior secured credit facilities also effectively limit our ability to pay dividends. Accordingly, you may have to sell some or all of your common stock in order to generate cash flow from your investment. You may not receive a gain on your investment when you sell your common stock and you may lose the entire amount of the investment.

Provisions of our amended and restated certificate of incorporation and amended and restated bylaws and Delaware law might discourage, delay or prevent a change of control of our company or changes in our management and, as a result, depress the trading price of our common stock.

        Our amended and restated certificate of incorporation and amended and restated bylaws contain provisions that could discourage, delay or prevent a change in control of our Company or changes in our management that the stockholders of our Company may deem advantageous. These provisions:

    establish a classified board of directors, with three classes of directors;

    authorize the issuance of blank check preferred stock that our board of directors could issue to increase the number of outstanding shares and to discourage a takeover attempt;

    limit the ability of stockholders to remove directors;

    prohibit our stockholders from calling a special meeting of stockholders;

    prohibit stockholder action by written consent, which requires all stockholder actions to be taken at a meeting of our stockholders;

    provide that our board of directors is expressly authorized to adopt, or to alter or repeal our bylaws; and

    establish advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted upon by stockholders at stockholder meetings.

        These anti-takeover defenses could discourage, delay or prevent a transaction involving a change in control of our Company. These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect directors of your choosing and cause us to take corporate actions other than those you desire.

Future sales of our common stock in the public market could lower our share price, and any additional capital raised by us through the sale of equity or convertible debt securities may dilute your ownership in us and may adversely affect the market price of our common stock.

        We and our existing stockholders may sell additional shares of common stock in subsequent public offerings. We may also issue additional shares of common stock or convertible debt securities to finance future acquisitions. As of September 30, 2014, we had 950,000,000 shares of common stock authorized and 97,010,286 shares of common stock outstanding. In addition, we have 2,638,256 shares of common stock issuable upon the exercise of options outstanding as of September 30, 2014 and 4,000,819 shares of common stock reserved for issuance under our 2011 Equity Incentive Award Plan.

        We cannot predict the size of future issuances of our common stock or the effect, if any, that future issuances and sales of our common stock will have on the market price of our common stock. Sales of substantial amounts of our common stock (including sales pursuant to Carlyle's registration rights and shares issued in connection with an acquisition), or the perception that such sales could occur, may adversely affect prevailing market prices for our common stock.

ITEM 2.    PROPERTIES

        Our global headquarters is located at 24911 Avenue Stanford, Valencia, California 91355. As of September 30, 2014, we have a total of 83 administrative, sales and/or stocking facilities located in 19 countries, all of which are either leased or located at a customer site, except for our global headquarters, which is owned by the Company.

        Our warehouse operations are divided between Central Stocking Locations, or CSLs, and Forward Stocking Locations, or FSLs. Our CSLs serve as the primary supply warehouses for most of our net sales and also house our procurement, customer service, document control, IT, material support and quality assurance functions. Our CSLs are supported by sales offices throughout the U.S., Canada, China, France, Germany, India, Israel, Italy, Singapore and the United Kingdom.

        Complementing our CSLs and sales offices are FSLs. An FSL is a specialized stocking point for one or more Contracts located within a geographic region. FSLs are typically located either near or within a customer facility and are established to support large Contracts. In certain instances, FSLs initially established to service a single customer are expanded to service other regional customers.

        The following table sets forth certain information regarding these facilities:

ITEM 7.    MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

        The following discussion and analysis is intended to help the reader understand our business, financial condition, results of operations, liquidity and capital resources. You should read this discussion in conjunction with our consolidated financial statements and the related notes contained elsewhere in this Annual Report on Form 10-K.

        The statements in this discussion regarding industry trends, our expectations regarding our future performance, liquidity and capital resources and other non-historical statements are forward-looking statements. These forward-looking statements are subject to numerous risks and uncertainties, including, but not limited to, the risks and uncertainties described in Part I, Item 1A. "Risk Factors" and "Cautionary Note Regarding Forward- Looking Statements." Our actual results may differ materially from those contained in or implied by any forward-looking statements.

Executive Overview

        We are one of the world's largest distributors and providers of comprehensive supply chain management services to the global aerospace industry on an annual sales basis. Our services range from traditional distribution to the management of supplier relationships, quality assurance, kitting, JIT delivery and point-of-use inventory management. We supply over 575,000 active SKUs, including hardware, chemicals, electronic components, bearings, tools and machined parts. We serve our customers under both Contracts and ad hoc sales.

        Founded in 1953 by the father of our current CEO, Wesco has grown to serve over 8,300 customers, which are primarily in the commercial, military and general aviation sectors, including the leading OEMs and their subcontractors, through which we support nearly all major Western aircraft programs. We also service industrial customers, which include customers in the automotive, energy, pharmaceutical and electronics sectors. We have more than 2,700 employees and operate across 83 locations in 19 countries.

        On September 29, 2006, 100% of the outstanding stock of Wesco Aircraft Hardware, Wesco Aircraft Israel and the European entities of Flintbrook Ltd., Wesco Aircraft France and Wesco Aircraft Germany were acquired by Wesco Aircraft Holdings, Inc. The acquisition was completed in a leveraged transaction in which affiliates of Carlyle, the prior owner and certain employees of Wesco contributed the equity portion of the purchase price. The prior owner's and certain employees' investment represented a contribution of ownership in the predecessor company to the newly formed holding Company. In accordance with Accounting Standards Codification, or ASC 805, Business Combinations, the acquired assets and liabilities have been recorded at fair value for the interests acquired by new investors and at carryover basis for the continuing investors.

        On June 30, 2008, Wesco Aircraft Hardware acquired 100% of the outstanding stock of Airtechnics, Inc., or Airtechnics, a distributor of electronic components for the aerospace industry, which we refer to as the Airtechnics Acquisition. The acquisition was funded through a provision in the old credit facilities that provided for additional borrowing under existing credit terms. Operating cash was also used by us to pay a portion of the purchase price and cover transaction fees and expenses. The assets and liabilities have been recorded at fair value for the interests we acquired.

        On July 3, 2012, Wesco Aircraft, together with Wesco Aircraft Europe, acquired substantially all of the assets of Interfast, a Toronto-based value-added distributor of specialty fasteners, fastening systems and production installation tooling for the aerospace, electronics and general industrial markets for $131.9 million, which we refer to as the Interfast Acquisition. The Interfast Acquisition was funded with a combination of cash and borrowings under the Company's $150.0 million revolving facility.

Table of Contents

        On February 28, 2014, we acquired Haas, a provider of chemical supply chain management services to the commercial aerospace, airline, military, energy, and other markets, for a purchase price of $560.2 million. The acquisition of Haas was financed through a combination of a new term loan B facility (as defined below under "—Liquidity and Capital Resources—Credit Facilities—Senior Secured Credit Facilities"), cash on hand and drawings under the revolving facility (as defined below under "—Liquidity and Capital Resources—Credit Facilities—Senior Secured Credit Facilities"). As a result of the acquisition, Haas became a wholly-owned subsidiary of Wesco Aircraft.

Industry Trends Affecting Our Business

    Commercial Aerospace Market

        We rely on demand for new commercial aircraft for a significant portion of our sales. Commercial aircraft demand is driven by many factors, including airline passenger volumes, airline profitability, introduction of new aircraft models, general economic conditions and the aging life cycle of current fleets.

        During calendar 2008, 2009 and 2010, our customers were impacted by the global recession and weak demand for air passenger travel, which resulted in significant losses for the global airline industry. During calendar 2011, 2012, 2013 and the first nine months of 2014, as the global economy began to recover, airline passenger volumes began to increase. Increased passenger traffic volumes and the return to profitability of the global airline industry have renewed demand for commercial aircraft, particularly for more fuel-efficient models, such as the Boeing 787 and Airbus A350. Although demand for commercial aircraft increased in calendar 2011, 2012, 2013 and the first nine months of 2014, these increases have not yet fully translated to increased purchasing patterns by our customers. In addition, commercial MRO providers are expected to benefit from similar growth trends to those impacting the commercial OEM market, in particular, increased revenue passenger miles, which will in turn drive growth in the commercial fleet and greater utilization of existing aircraft. Growth in the commercial aerospace market is also expected to be aided by a recovery in business jet and regional jet deliveries.

    Military Aerospace Market

        A significant portion of our sales are also reliant on demand for new military aircraft, which is primarily driven by government spending, the timing of military aircraft orders and evolving U.S. Department of Defense strategies and policies. We believe the diversity of the military aircraft programs we service can help us mitigate the impact of program delays, changes or cancellations, through increased sales to other active programs that directly benefit from such delays, changes or cancellations. Going forward, we believe that we will benefit from increases in the production of the JSF, a program on which we believe our business is well positioned. We also believe that the compelling value proposition that our business model presents to our customers will be even more appealing in an environment of reduced military budgets in the United States.

        We also support customers in the military aerospace MRO market and believe that our presence in this market helps us mitigate the volatility of new military aircraft sales with sales to the aftermarket. We expect demand in the military MRO market to be driven by requirements to maintain aging military fleets, changes in the overall fleet size and the level of U.S. military activity overseas.

Other Factors Affecting Our Financial Results

    Fluctuations in Revenue

        There are many factors, such as fluctuations in ad hoc sales, timing of aircraft deliveries, changes in selling prices, the amount of new customers' consigned inventory and the volume or timing of customer orders that can cause fluctuations in our financial results from quarter-to-quarter. To

36


Table of Contents

normalize for short-term fluctuations, we tend to look at our performance over several quarters or years of activity rather than discrete short-term periods. As such, it can be difficult to determine longer-term trends in our business based on quarterly comparisons.

        We will continue our strategy of seeking to expand our relationships with existing customers by transitioning them to Contracts, as well as expanding relationships with our existing Contract customers to include additional customer sites, additional SKUs and additional levels of service. We believe this strategy serves to mitigate fluctuations in our net sales. However, our sales to Contract customers may fail to meet our expectations for a variety of reasons, in particular if industry build rates are lower than expected or, for certain newer JIT customers, if their consigned inventory, which must be exhausted before corresponding products are purchased directly from us, is larger than we expected.

        During fiscal 2014, we modified and extended a contract with an existing customer that may result in up to a $50 million reduction in net sales to the customer during fiscal 2015 compared to fiscal 2014.

        If any of our customers are acquired or controlled by a company that elects not to utilize our services, or attempt to implement in-sourcing initiatives, it could have a negative effect on our strategy to mitigate fluctuations in our net sales. Additionally, although we derive a significant portion of our net sales from the building of new commercial and military aircraft, we have not typically experienced extreme fluctuations in our net sales when sales for an individual aircraft program decrease, which we believe is attributable to our diverse base of customers and programs. In addition, we believe our substantial sales under Contracts helps to mitigate fluctuations in our financial results, as Contract customers tend to have steadier purchasing patterns than ad hoc customers. However, as mentioned above, our sales to Contract customers may fail to meet our expectations for a variety of reasons, in particular if industry build rates are lower than expected or, for certain newer JIT customers, if their consigned inventory, which must be exhausted before corresponding products are purchased directly from us, is larger than we expected or if estimated usage rates are actually lower. In addition, we believe that during industry growth cycles, our customer's demand may begin to exceed supplier lead times, which could result in an increase in our ad hoc sales.

    Fluctuations in Margins

        We added chemicals to our product offerings in connection with our acquisition of Haas on February 28, 2014. Gross profit margins on chemicals are lower than the gross profit margins on many of the products we sold prior to the acquisition of Haas, which we believe will result in a reduction in our overall gross profit margins. In addition, we believe our gross profit margins may also be negatively impacted to the extent other lower margin product lines, such as electronic components, exceeds the growth rates of higher margin product lines. In addition, there continues to be pricing pressure throughout the supply chain.

        We also believe that our strategy of growing our Contract sales and converting ad hoc customers into Contract customers could negatively affect our gross profit margins, as gross profit margins tend to be higher on ad hoc sales than they are on Contract-related sales. However, we believe any potential adverse impact on our gross profit margins is outweighed by the benefits of a more stable long-term revenue stream attributable to Contract customers.

        During fiscal 2013 and 2014, we saw increased competition in the ad hoc market, which has slightly reduced our typically higher ad hoc margins, and we expect the current margins to remain relatively consistent throughout fiscal 2015. However, we believe that as industry build rates and manufacturer lead times increase, margins on ad hoc sales will begin to increase.

        Our Contracts generally provide for fixed prices, which can expose us to risks if prices we pay to our suppliers rise due to increased raw material or other costs. However, we believe our expansive

product offerings and inventories, our ad hoc sales and, where possible, our longer-term agreements with suppliers have enabled us to mitigate this risk.

    Fluctuations in Cash Flow

        We believe our cash flows may be affected by fluctuations in our inventory that can occur over time. When we are awarded new programs, we generally increase our inventory to account for expected sales related to the new program, which often take time to materialize. As a result, if certain programs for which we have procured inventory are delayed or if certain newer JIT customers' consigned inventory is larger than we expected, we may experience a more sustained inventory increase. For example, we increased our inventory in anticipation of deliveries of the Boeing 787, which experienced significant delays.

        Inventory fluctuations may also be attributable to general industry trends. For example, as production in the global aerospace industry increases, we typically see an increase in demand from our customers and a delay in deliveries from certain of our suppliers, which tends to result in a temporary inventory reduction and increased cash flow. However, when production in the aerospace industry decreases, our suppliers are able to catch up on our outstanding orders, while demand from our customers decreases, which tends to result in an increase in inventory levels and decreased cash flow. Although we have made, and continue to make, adjustments to our purchasing practices in order to mitigate the effect of inventory fluctuations on our cash flows, inventory fluctuations continue to occur and, as a result, will continue to impact our cash flows. During fiscal 2013 and 2014, we experienced inventory builds of approximately $72.6 million and $55.0 million, respectively, which were primarily driven by strategic purchases (i) to take advantage of favorable pricing, (ii) in anticipation of the expected industry growth cycle and (iii) to support new customer Contracts. We would expect inventory to continue to grow as net sales increase.

        Given that growth in our business typically requires us to procure additional inventory, which has a negative impact on our cash flows, we believe that cost of sales as a percentage of inventory is a useful additional metric to use when analyzing our inventory management relative to the growth of our business. Our cost of sales as a percentage of inventory increased from 91.9% for fiscal 2013 to 98.0% for fiscal 2014 (exclusive of any net sales or inventory attributable to the Haas business), which we believe reflects a positive trend in our inventory management relative to the growth of our business. However, we believe that fluctuations in our cost of sales as a percentage of inventory, including deviations from what we believe are longer-term trends, will continue to occur from time-to-time. Factors that may contribute to fluctuations in our cost of sales as a percentage of inventory in the future could include (i) strategic purchases (a) to take advantage of favorable pricing, (b) made in anticipation of the expected industry growth cycle, (c) to support new customer Contracts or (d) to acquire high-volume products that are typically difficult to obtain in sufficient quantities, (ii) changes in supplier lead times and the timing of inventory deliveries, (iii) purchases made in anticipation of future growth (particularly growth in our MRO business) and (iv) purchases made in connection with the expansion of existing Contracts.

        Although we believe that during fiscal 2013 and 2014, the aerospace industry was experiencing a growth cycle, and accordingly made strategic inventory purchases, the typical increases in customer demand and supplier lead times that occur during growth cycles have not occurred within the expected time frame. We believe that this lower than expected demand is the result of inventory purchases that remain in the supply chain from the last downturn and that it is taking longer for those parts to sell-off. Accordingly, we believe that the strategic inventory purchases we made during fiscal 2013 and 2014, combined with this lower-than-expected demand, has had a negative impact on our cash flows.

Table of Contents

        Our accounts receivable balance as a percentage of net sales may fluctuate from quarter-to-quarter. These fluctuations are primarily driven by changes, from quarter-to-quarter, in (i) the timing of sales and (ii) the current average days' sales outstanding. The completion of customer Contracts with accelerated payment terms can also contribute to these quarter-to-quarter fluctuations. Similarly, our accounts payable may fluctuate from quarter-to-quarter, which is primarily driven by the timing of purchases or payments made to our suppliers.

Segment Presentation

        We conduct our business through two reportable segments: North America and Rest of World. We evaluate segment performance based on segment operating earnings or losses. Each segment reports its results of operations and makes requests for capital expenditures and acquisition funding to our chief operating decision maker, or CODM. Our CEO serves as our CODM.

Key Components of Our Results of Operations

        The following is a discussion of the key line items included in our financial statements for the periods presented below under the heading "Results of Operations." These are the measures that management utilizes to assess our results of operations, anticipate future trends and evaluate risks in our business.

    Net Sales

        Our net sales include sales of hardware, chemicals, electronic components, bearings, tools and machined parts, and eliminate all intercompany sales. We also provide certain services to our customers, including quality assurance, kitting, JIT delivery and point-of-use inventory management. However, these services are provided by us contemporaneously with the delivery of the product, and as such, once the product is delivered, we do not have a post-delivery obligation to provide services to the customer. Accordingly, the price of such services is generally included in the price of the products delivered to the customer, and revenue is recognized upon delivery of the product, at which point, we have satisfied our obligations to the customer. We do not account for these services as a separate element, as the services do not have stand-alone value and cannot be separated from the product element of the arrangement.

        We serve our customers under both (i) Contracts, which include JIT contracts and LTAs, and (ii) ad hoc sales. Under JIT contracts, customers typically commit to purchase specified products from us at a fixed price, on an if-and-when needed basis, and we are responsible for maintaining high levels of stock availability of those products. LTAs are typically negotiated price lists for customers or individual customer sites that cover a range of pre-determined products, purchased on an as-needed basis. Ad hoc customers purchase products from us on an as-needed basis and are generally supplied out of our existing inventory. In addition, Contract customers often purchase products that are not captured under their Contract on an ad hoc basis.

    Operating Earnings

        Operating earnings (which is the same as income from operations) are the result of subtracting the cost of sales and selling, general, and administrative expenses from net sales, and are used primarily to evaluate the Company's performance and profitability.

        The principal component of our cost of sales is product cost, which was approximately 97.4% of our total cost of sales for fiscal 2014. The remaining components are freight and expediting fees, import duties, tooling repair charges, packaging supplies and physical inventory adjustment charges, which collectively were approximately 2.6% of our total cost of sales for fiscal 2014.

Table of Contents

        Product cost is determined by the current weighted average cost of each inventory item, except for chemical parts for which FIFO is used and inventory excess and obsolescence write-down. Inventory write-down is calculated to estimate the amount of excess and obsolete inventory we currently have on-hand. We review inventory for excess and obsolescence write-down quarterly and adjust the expense and future forecasted sell-through rates as necessary. For a description of our excess and obsolescence reserve policy, see "—Critical Accounting Policies and Estimates—Inventories." As of September 30, 2014, 2013 and 2012, we had recorded an aggregate of approximately $143.7 million, $121.1 million and $109.3 million, respectively, to our excess and obsolescence reserve. Of these amounts, approximately $17.7 million, $8.7 million and $13.1 million were recorded during fiscal 2014, 2013 and 2012, respectively. We believe that these amounts appropriately reflect the risk of excess and obsolete inventory inherent in our business. The increase in fiscal 2014 as compared to fiscal 2013 is primarily due to an additional $3.3 million (which is higher than our typical level) recorded in fiscal 2014 as well as the impact of the $55.0m inventory growth during the fiscal year. In addition, fiscal 2013 included a benefit as a result of the Interfast acquisition. For a more detailed description of the excess and obsolescence reserves, see Note 5 of the Notes to Consolidated Financial Statements in Part II, Item 8 of this Annual Report on Form 10-K.

        The principal components of our selling, general and administrative expenses are salaries, wages, benefits and bonuses paid to our employees; stock-based compensation; commissions paid to outside sales representatives; travel and other business expenses; training and recruitment costs; marketing, advertising and promotional event costs; rent; bad debt expense; professional services fees (including legal, audit and tax); and ordinary day-to-day business expenses. Depreciation and amortization expense is also included in selling, general and administrative expenses, and consists primarily of scheduled depreciation for leasehold improvements, machinery and equipment, vehicles, computers, software and furniture and fixtures. Depreciation and amortization also includes intangible amortization expense.

    Other Expenses

        Interest Expense, Net.    Interest expense, net consists of the interest we pay on our long-term debt, fees on our revolving facility (as defined below under "—Liquidity and Capital Resources—Credit Facilities—Senior Secured Credit Facilities") and our line-of-credit and deferred financing costs, net of interest income.

        Other Income (Expense), Net.    Other income (expense), net is primarily comprised of unrealized foreign exchange gain or loss associated with transactions denominated in currencies other than the respective functional currency of the reporting subsidiary.

Critical Accounting Policies and Estimates

        The methods, estimates and judgments we use in applying our most critical accounting policies have a significant impact on the results we report in our financial statements. We evaluate our estimates and judgments on an on-going basis. We base our estimates on historical experience and on assumptions that we believe to be reasonable under the circumstances. Our experience and assumptions form the basis for our judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may vary from what we anticipate, and different assumptions or estimates about the future could change our reported results. We believe the following accounting policies are the most critical in that they significantly affect our financial statements, and they require our most significant estimates and complex judgments.

    Inventories

        Our inventory is comprised solely of finished goods. Inventories are stated at the lower of cost or market. The method by which amounts are removed from inventory are weighted average cost for all

40


Table of Contents

inventory, except for chemical parts for which FIFO is used. In-bound freight-related costs are included as part of the cost of inventory held for resale. We record provisions, as appropriate, to write-down excess and obsolete inventory to estimated net realizable value. The process for evaluating excess and obsolete inventory often requires us to make subjective judgments and estimates concerning future sales levels, quantities and prices at which such inventories will be able to be sold in the normal course of business, which is described in greater detail below under "—Excess and Obsolescence Reserve Policy."

        Demand for our products can fluctuate significantly. Our estimates of future product demand may prove to be inaccurate, in which case we may have understated or overstated the write-down required for excess and obsolete inventories. In the future, if our inventories are determined to be overvalued, we would be required to recognize such costs in our cost of goods sold at the time of such determination.

    Excess and Obsolescence Reserve Policy

        We perform a monthly inventory analysis and record excess and obsolescence expense after weighing a number of factors, including historical sell-through rates, current selling and buying patterns, forecasted future sales, program delays or cancellations, inventory quantities and aging, shelf-life expiration, damage to products, rights we have with certain manufacturers to exchange unsold products for new products and open customer orders. For our chemical products, we do not reserve for items where the customer is responsible for any excess or obsolete product.

        The excess and obsolescence reserve includes both excess and slow-moving inventory which typically includes inventory held by us after strategic purchases are made to take advantage of favorable pricing terms, speculative purchases based on current market trends or purchases timed to take supplier lead times into account, which may result in us maintaining excess and slow-moving quantities of inventories.

        In conducting our monthly reserve analysis with respect to slow-moving inventory, we consider a variety of factors, including historical sell-through rates, current selling and buying patterns, inventory quantities and aging, shelf-life expiration, damage to products, rights we have with certain manufacturers to exchange unsold products for new products and open customer orders. Furthermore, although our customers are not required to purchase a specific quantity of inventory from us, we are able to forecast future sales with a fair degree of precision by monitoring and tracking our customers' production cycles, which forecasting is taken into account when conducting our reserve analysis. We further note that we are required to make commitments to purchase inventory based on manufacturer lead times, which, historically could be up to two years. In addition, we may be entitled to obtain price breaks or discounts based on the quantity of inventory we commit to purchase. Given the length of our manufacturers' lead times, our desire to obtain advantageous inventory pricing, the impact of macro and micro economic conditions and variability within specific customer programs which can impact the amount of slow-moving inventory we hold, our inventory reserve may increase at a rate higher than we originally anticipated.

        Based on our historical experience, we have limited exposure related to our non-excess and non-slow-moving inventory, as a majority of the products we sell can be sold across multiple aircraft platforms and the lifespan of the products we sell along with the design of the aircrafts that utilize these products is typically not subject to a high degree of obsolescence. However, our chemical inventory becomes obsolete when it has aged past its shelf-life, cannot be recertified and is no longer usable or able to be sold, or the inventory has been damaged on-site or in-transit. In such instances, a full reserve is taken against such inventory. In certain cases, as determined by the applicable contract, the customer is responsible for excess or obsolete chemical product, and in such instances, no reserve is recorded for the applicable product. Furthermore, we do take program delays, cancellations as well as positive and negative factors into account when conducting the reserve analysis.

    Goodwill and Indefinite-Lived Intangible Assets

        Goodwill represents the excess of the consideration paid over the fair value of the net assets acquired in a business combination. In accordance with the provisions of ASC 350, Intangibles—Goodwill and Other, goodwill and indefinite-lived intangible assets acquired in a business combination are not amortized, but instead tested for impairment at least annually or more frequently should an event occur or circumstances indicate that the carrying amount may be impaired. Such events or circumstances may be a significant change in business climate, economic and industry trends, legal factors, negative operating performance indicators, significant competition, changes in strategy, or disposition of a reporting unit or a portion thereof. Goodwill and indefinite lived intangibles impairment testing is performed at the reporting unit level on July 1 of each year.

        Step 0 allows an entity the option to first assess qualitative factors to determine whether an impairment to either goodwill or indefinite lived intangible assets is more likely than not (that is, a likelihood of more than 50 percent) that the fair value of a reporting unit is less than its carrying amount. Such qualitative factors may include the following: macroeconomic conditions; industry and market considerations; cost factors; overall financial performance; entity specific operating results and other relevant entity-specific events. If the entity elects to perform a qualitative assessment and determines that an impairment is more likely than not, the entity is then required to perform the two-step quantitative impairment test which is used to identify potential goodwill impairments and to measure the amount of goodwill impairment losses to be recognized, if any; otherwise, no further analysis is required. An entity also may elect not to perform the qualitative assessment and, instead, proceed directly to the two-step quantitative impairment test.

        The first step identifies potential impairment by comparing the fair value of a reporting unit with its carrying amount, including goodwill. For periods prior to the Haas acquisition, our reporting units are consistent with our reporting units. Subsequent to the Haas acquisition, we added two additional reporting units (Haas North America and Haas Rest of World). The estimates of fair value of a reporting unit are determined based on a discounted cash flow analysis and market earnings multiples. A discounted cash flow analysis requires us to make various judgmental assumptions, including assumptions about future cash flows, growth rates and discount rates. The assumptions about future cash flows and growth rates are based on the forecast and long-term business plans of each reporting unit. Discount rate assumptions are based on an assessment of the risk inherent in the future cash flows of the respective reporting units. If the fair value exceeds the carrying value of a reporting unit, goodwill is not considered impaired and the second step of the test is unnecessary. If the carrying amount of a reporting unit's goodwill exceeds the fair value of a reporting unit, the second step measures the impairment loss, if any.

        The second step compares the implied fair value of goodwill with the carrying amount of that goodwill. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination. If the carrying amount of goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess.

        Application of the goodwill impairment test requires judgment, including the identification of reporting units, assignment of assets and liabilities to reporting units, assignment of goodwill to reporting units, and determination of the fair value of each reporting unit. Changes in these estimates and assumptions could materially affect the determination of fair value and/or goodwill impairment for each reporting unit.

        The Company tests its indefinite-lived intangible asset, consisting of the Wesco trademark, for impairment on July 1 each year, or whenever events or circumstances indicate that it is more likely than not that its carrying value exceed its fair values. Fair value is estimated as the discounted value of tax effected future revenues using a royalty rate that a third party would pay for use of the asset.

42


Table of Contents

Variation in the royalty rate used could impact the estimate of fair value. If the carrying amount of an asset exceeds its implied fair value, an impairment loss is recognized in an amount equal to that excess.

        We reviewed the carrying value of our reporting units and indefinite-lived intangible assets by comparing such amount to its fair value and determined that the carrying amount did not exceed its respective fair value. During the years ended September 30, 2014, 2013 and 2012, the fair value of our reporting units was in excess of the reporting units' carrying values. Additionally, the fair value of our indefinite-lived intangible assets was substantially in excess of its carrying value. There were no impairment indicators noted during the period. Accordingly, management believes there are no impairments as of September 30, 2014 related to either goodwill or the indefinite-lived intangible asset.

    Revenue Recognition

        We recognize product and service revenue when (i) persuasive evidence of an arrangement exists, (ii) title transfers to the customer, (iii) the sales price charged is fixed or determinable and (iv) collection is reasonably assured. In instances where title does not pass to the customer upon shipment, we recognize revenue upon delivery or customer acceptance, depending on the terms of the sales contract.

        In connection with the sale of our products, we often provide certain supply chain management services to our JIT customers. These services include the timely replenishment of products at the customer site, while also minimizing the customer's on-hand inventory. These services are provided by us contemporaneously with the delivery of the product, and as such, once the product is delivered, we do not have a post-delivery obligation to provide services to the customer. Accordingly, the price of such services is generally included in the price of the products delivered to the customer, and revenue is recognized upon delivery of the product, at which point, we have satisfied our obligations to the customer. We do not account for these services as a separate element, as the services do not have stand-alone value and cannot be separated from the product element of the arrangement. Additionally, the Company does not present service revenues apart from product revenues, as the service fee revenues represent less than 1% of the Company's consolidated net sales.

        We report revenue on a gross or net basis based on management's assessment of whether we act as a principal or agent in the transaction and in accordance with the guidance of ASC 605-45-45, Revenue Recognition-Principal Agent Considerations, in our presentation of net sales and costs of revenue. This guidance requires us to assess whether we act as a principal in the transaction or as an agent acting on behalf of others. If we are the principal in the transaction and have the risks and rewards of ownership, the transactions are recorded as gross in the consolidated statements of earnings. If we do not act as a principal in the transaction, the transactions are recorded on a net basis in the consolidated statement of comprehensive income. The majority of the Company's revenue is recorded on a gross basis with the exception of certain gas, energy and chemical manager service contracts that are recorded as net revenue.

        We also enter into sales rebate and profit sharing arrangements. Such customer incentives are accounted for as a reduction to gross sales and recorded based upon estimates at the time products are sold. These estimates are based upon historical experience for similar programs and products. We review such rebates and profit sharing arrangements on an ongoing basis and accruals are adjusted, if necessary, as additional information becomes available.

        Management provides allowances for credits and returns, based on historic experience, and adjusts such allowances as considered necessary. To date, such provisions have been within the range of management's expectations and the allowance established. Sales tax collected from customers is excluded from net sales in the accompanying consolidated statements of income.

    Income Taxes

        We account for income taxes in accordance with ASC 740, Income Taxes. ASC 740, which requires the recognition of deferred tax liabilities and assets for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which these temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is established, when necessary, to reduce net deferred tax assets to the amount expected to be realized. Our foreign subsidiaries are taxed in local jurisdictions at local statutory rates.

        The Company determines whether it is more likely than not that some or all of the deferred tax assets will not be realized. Therefore, a valuation allowance has been recorded against these deferred tax assets. The taxes associated with the undistributed earnings would be between $10,000 and $15,000. It is reasonably possible that within the next twelve months approximately $1,100 may be recognized as a result of the lapsing of the statute of limitation.

    Stock-Based Compensation

        We account for all stock-based compensation awards to employees and members of our board of directors based upon their fair values as of the date of grant using a fair value method and recognize the fair value of each award as an expense over the requisite service period using the graded vesting method.

        For purposes of calculating stock-based compensation, we estimate the fair value of stock options using a Black-Scholes-Merton valuation model, which requires the use of certain subjective assumptions including expected term, volatility, expected dividend, risk-free interest rate, and the fair value of our common stock. These assumptions generally require significant judgment.

        We estimate the expected term of employee options using the average of the time-to-vesting and the contractual term. We derive our expected volatility from the historical volatilities of several unrelated public companies within our industry because we have little information on the volatility of the price of our common stock since we have limited trading history. When making the selections of our industry peer companies to be used in the volatility calculation, we also consider the size and financial leverage of potential comparable companies. These historical volatilities are weighted based on certain qualitative factors and combined to produce a single volatility factor. Our expected dividend rate is zero, as we have never paid any dividends on our common stock and do not anticipate any dividends in the foreseeable future. We base the risk-free interest rate on the U.S. Treasury yield in effect at the time of grant for zero coupon U.S. Treasury notes with maturities approximately equal to each grant's expected life.

        We estimate our forfeiture rate based on an analysis of our actual forfeitures and will continue to evaluate the appropriateness of the forfeiture rate based on actual forfeiture experience, analysis of employee turnover behavior and other factors. Quarterly changes in the estimated forfeiture rate can have a significant effect on reported stock-based compensation expense, as the cumulative effect of adjusting the rate for all expense amortization is recognized in the period the forfeiture estimate is changed. If a revised forfeiture rate is higher than the previously estimated forfeiture rate, an adjustment is made that will result in a decrease to the stock-based compensation expense recognized in the consolidated financial statements. If a revised forfeiture rate is lower than the previously estimated forfeiture rate, an adjustment is made that will result in an increase to the stock-based compensation expense recognized in the consolidated financial statements.

Non-cash stock-based compensation

  $ 5,507   $ 3,394   $ 1,626  

        For the years ending September 30, 2015 and 2016, we expect to incur stock-based compensation expense of approximately $4.8 million and $2.7 million, respectively.

        If factors change and we employ different assumptions, stock-based compensation expense may differ significantly from what we have recorded in the past. If there is a difference between the assumptions used in determining stock-based compensation expense and the actual factors that become known over time, we may change the input factors used in determining stock-based compensation costs for future grants. These changes, if any, may materially impact our results of operations in the period such changes are made. We expect to continue to grant stock options in the future, and to the extent that we do, our actual stock-based compensation expense recognized in future periods will likely increase.

        Consolidated net sales of $1,355.9 million for the year ended September 30, 2014 increased approximately $454.3 million, or 50.4%, compared to the year ended September 30, 2013. Ad hoc and Contract sales as a percentage of net sales represented 28% and 72%, respectively, for the year ended September 30, 2014, as compared to 40% and 60%, respectively, for the year ended September 30, 2013. The year ended September 30, 2014 reflects $356.2 million of sales related to the acquisition of Haas, and exclusive of these net sales the increase in net sales would have been $98.1 million, or 10.9%.

        Net sales of $1,030.5 million in our North America segment for the year ended September 30, 2014 increased approximately $316.8 million, or 44.4%, compared to the year ended September 30, 2013. The year ended September 30, 2014 reflects $266.3 million of net sales related to the acquisition of Haas, and exclusive of these net sales North America net sales would have increased by $50.6 million, or 7.1%. Excluding the acquisition of Haas, ad hoc and Contract net sales increased by $7.1 million or 2.3% and $46.9 million or 11.7%, respectively, for the year ended September 30, 2014 as compared to the year ended September 30, 2013. The increase in ad hoc net sales was primarily due to general growth across numerous customers. The increase in Contract net sales was primarily driven by a transition of a contract from Rest of World to North America, a settlement related to the termination of a contract, increases in commercial build rates for existing Contracts and scope expansion on existing Contracts.

        Net sales of $325.4 million in our Rest of World segment for the year ended September 30, 2014 increased approximately $137.5 million, or 73.2%, compared to the year ended September 30, 2013. The year ended September 30, 2014 reflects $90.0 million of net sales related to the acquisition of Haas, and exclusive of these net sales Rest of World net sales would have increased by $47.5 million, or 25.3%. Excluding the acquisition of Haas, ad hoc and Contract net sales increased by $3.0 million or 6.7% and $45.3 million or 31.8%, respectively, for the year ended September 30, 2014 as compared to the year ended September 30, 2013. The ad hoc net sales growth was attributable to increases in European production and growth across the customer base due to build rate increases and expansion of the MRO market. The drivers of the increase in Contract sales were a one-time inventory sale in

conjunction with the modification and extension of a contract with an existing customer as well as further growth of the Boeing 787 production and higher build rates with European commercial customers. These increases were partially offset by a transition of a contract to North America.

    Operating Earnings

        Consolidated operating earnings of $183.9 million for the year ended September 30, 2014 increased approximately $3.1 million, or 1.7%, compared to the year ended September 30, 2013. Operating earnings as a percentage of net sales was 13.6% for the year ended September 30, 2014, compared to 20.1% for the year ended September 30, 2013.

        Operating earnings of $145.3 million in our North America segment for the year ended September 30, 2014 decreased approximately $5.2 million, or 3.5%, compared to the year ended September 30, 2013. Operating earnings as a percentage of net sales in our North America segment were 14.1% for the year ended September 30, 2014, compared to 21.1% for the year ended September 30, 2013, a decrease of 7.0%. The decrease in operating earnings as a percentage of net sales was partially driven by $12.6 million of costs associated with the Haas acquisition, which resulted in a decrease of 1.2%. The other primary drivers of this decrease were 2.4% related to margin impact attributable to the Haas acquisition and 2.6% related to a decrease in margins (exclusive of the impact of the Haas acquisition) of which 1.1% is due to a $8.6 million increase in the excess and obsolescence inventory reserve and the remaining 1.5% is a result of higher lower-margin Contract sales and discounts provided to customers in exchange for long-term contracts extensions. In addition, 0.7% of the decrease related to higher selling, general and administrative expenses, of which 0.5% was attributable to the Haas acquisition.

        Operating earnings of $38.6 million in our Rest of World segment for the year ended September 30, 2014 increased approximately $8.4 million, or 27.7%, compared to the year ended September 30, 2013. Operating earnings as a percentage of net sales in our Rest of World segment was 11.9% for the year ended September 30, 2014, compared to 16.1% for the year ended September 30, 2013, a decrease of 4.2%. The decrease in operating earnings as a percentage of net sales was primarily driven by the Haas acquisition, with 1.4% related to margins and 2.0% related to additional selling, general and administrative expenses as a result of the acquisition. In addition, the strong growth in lower-margin Contracts sales decreased operating earnings as a percentage of net sales by 1.8% (exclusive of the impact of the Haas acquisition). These decreases were partially offset by a 1.1% decline in selling, general and administrative expenses (exclusive of the impact of the Haas acquisition) as a percentage of sales due to operating leverage as our revenues have increased.

    Other Expenses

    Interest Expense, Net

        Interest expense, net of $29.2 million for the year ended September 30, 2014 increased approximately $4.0 million, or 16.1%, compared to the year ended September 30, 2013. This increase was driven by $12.1 million of interest incurred during the year ended September 30, 2014 associated with the term loan B facility and the revolving facility that were used to fund the Haas acquisition that occurred on February 28, 2014. This increase was partially offset by a reduction in the average term loan A facility balance of $26.7 million for the year ended September 30, 2014 as compared to September 30, 2013, as well as $5.0 million write-off of deferred financing charges related to the refinancing of the old senior secured credit facilities during the year ended September 30, 2013 (as defined below under "—Liquidity and Capital Resources—Credit Facilities—Old Senior Secured Credit Facilities").

    Other Income (Expense), Net

        Other income, net of $2.2 million for the year ended September 30, 2014 increased by $0.2 million compared to the year ended September 30, 2013. This change was primarily due to unrealized foreign exchange gains associated with transactions denominated in currencies other than the respective functional currency of the reporting subsidiary.

    Provision for Income Taxes

        The provision for income taxes of $54.8 million for the year ended September 30, 2014 increased by $2.0 million compared to the year ended September 30, 2013. Our effective tax rate was 34.93% and 33.51% during the year ended September 30, 2014 and 2013, respectively. The increase in our effective tax rate resulted primarily from an increase in certain expenses related to the Haas acquisition which are not tax deductible. Please see Note 12 of Notes to Consolidated Financial Statements in Part II, Item 8 of this Annual Report on Form 10-K for additional information about our provision for income taxes during the year ended September 30, 2014.

    Net Income

        We reported net income of $102.1 million for the year ended September 30, 2014, compared to net income of $104.8 million for the year ended September 30, 2013. Net income as a percent of net sales decreased 4.1% for the year ended September 30, 2014, as compared to the year ended September 30, 2013, due to lower operating earnings, as discussed above, partially offset by lower interest expense as a percent of net sales and a lower provision for income taxes as a percent of net sales.

Year Ended September 30, 2013 compared with the Year Ended September 30, 2012

    Net Sales

        Consolidated net sales of $901.6 million for the year ended September 30, 2013 increased approximately $125.4 million, or 16.2%, compared to the year ended September 30, 2012. This growth in net sales includes the Interfast Acquisition, which occurred on July 3, 2012. Ad hoc and Contract sales as a percentage of net sales represented 40% and 60%, respectively, for the year ended September 30, 2013, as compared to 38% and 62%, respectively, for the year ended September 30, 2012.

        Net sales of $713.7 million in our North America segment for the year ended September 30, 2013 increased approximately $84.9 million, or 13.5%, compared to the year ended September 30, 2012. This growth was partially driven by sales related to the Interfast Acquisition. Ad hoc and Contract net sales increased by $46.0 million or 17.2% and $38.2 million or 10.5%, respectively, for the year ended September 30, 2013 as compared to the year ended September 30, 2012. The increase in ad hoc net sales is primarily due to general growth across numerous customers and the Interfast Acquisition. The increase in Contract net sales was primarily due to the maturity of our existing Contracts, as well as the additions of new locations for some of our major customers and general growth across the customer base partially offset by a non-recurring contract sale with a customer that took place during the three months ended December 31, 2011.

        Net sales of $187.9 million in our Rest of World segment for the year ended September 30, 2013 increased approximately $40.5 million, or 27.5%, compared to the year ended September 30, 2012. Ad hoc and Contract net sales increased by $12.5 million or 38.8% and $26.8 million or 23.1%, respectively, for the year ended September 30, 2013 as compared to the year ended September 30, 2012. The increase in ad hoc net sales was driven by growth across the customer base as a result of higher build rates. The growth in Contract net sales reflected the continued ramp up of Boeing 787 production and Airbus platforms, as well as higher content and higher build rates among other

    Operating Earnings

        Consolidated operating earnings of $180.8 million for the year ended September 30, 2013 increased approximately $22.0 million, or 13.8%, compared to the year ended September 30, 2012. Operating earnings as a percentage of net sales was 20.1% for the year ended September 30, 2013, compared to 20.5% for the year ended September 30, 2012.

        Operating earnings of $150.6 million in our North America segment for the year ended September 30, 2013 increased approximately $12.2 million, or 8.8%, compared to the year ended September 30, 2012. Operating earnings as a percentage of net sales in our North America segment were 21.1% for the year ended September 30, 2013, compared to 22.0% for the year ended September 30, 2012, a decrease of 0.9%. The decrease in operating earnings as a percentage of net sales was partially driven by $3.7 million of costs associated with the Interfast Acquisition, which resulted in a decrease of 0.5%. The other primary driver of this decrease was 0.6% related to a decrease in our margins as a result of changes in our sales mix, including higher EPG sales and a decline in our ad hoc margins due to a competitive ad hoc market and the Interfast Acquisition. These decreases were slightly offset by a 0.2% decline in our selling, general and administrative expenses (exclusive of the impact of the Interfast Acquisition) as a percentage of sales.

        Operating earnings of $30.2 million in our Rest of World segment for the year ended September 30, 2013 increased approximately $9.8 million, or 47.8%, compared to the year ended September 30, 2012. Operating earnings as a percentage of net sales in our Rest of World segment was 16.1% for the year ended September 30, 2013, compared to 13.9% for the year ended September 30, 2012, an increase of 2.2%. The strong growth of lower margin Contract net sales and pressure on ad hoc margins due to a competitive market decreased our operating margins as a percentage of net sales by 0.6%. This decrease was offset by a decline in our selling, general and administrative expenses as a percentage of net sales due to operating leverage as our revenues have increased significantly.

    Other Expenses

    Interest Expense, Net

        Interest expense, net of $25.2 million for the year ended September 30, 2013 decreased approximately $0.5 million, or 2.2%, compared to the year ended September 30, 2012. This decrease was primarily the result of an increase of $33.7 million in the average outstanding debt balances and a $5.0 million write-off of deferred financing charges related to the refinancing of the old senior secured credit facilities during the year ended September 30, 2013. These increases were partially offset by a 1.15% interest rate reduction due to the refinancing of the old senior secured credit facility.

    Other Income (Expense), Net

        Other income, net of $2.0 million for the year ended September 30, 2013 increased by $2.5 million compared to the year ended September 30, 2012. This change was primarily due to unrealized foreign exchange gains associated with transactions denominated in currencies other than the respective functional currency of the reporting subsidiary.

    Provision for Income Taxes

        Provision for income taxes of $52.8 million for the year ended September 30, 2013 increased approximately $11.3 million compared to the year ended September 30, 2012. Our effective tax rate was 33.51% and 31.04% during the years ended September 30, 2013 and September 30, 2012, respectively.

The increase in provision for income taxes was primarily related to deemed dividends from certain of the Company's foreign subsidiaries.

    Net Income

        We reported net income of $104.8 million for the year ended September 30, 2013, compared to net income of $92.2 million for the year ended September 30, 2012. Net income as a percent of net sales decreased 0.3% for the year ended September 30, 2013 as compared to the year ended September 30, 2012, due to lower operating earnings, as described above, as well as a higher provision income taxes as a percent of net sales partially offset by lower interest expenses as a percent of net sales and higher other income as a percent of net sales.

Liquidity and Capital Resources

    Overview

        Our primary sources of liquidity are cash flow from operations and available borrowings under our revolving facility (as defined below under "—Credit Facilities—Senior Secured Credit Facilities"). We have historically funded our operations, debt payments, capital expenditures and discretionary funding needs from our cash from operations. We had total available cash and cash equivalents of approximately $104.8 million and $78.7 million as of September 30, 2014 and 2013, respectively, of which approximately $56.0 million, or 53.5%, and $13.8 million, or 17.5%, was held by our foreign subsidiaries as of September 30, 2014 and 2013, respectively. None of our cash and cash equivalents consisted of restricted cash and cash equivalents as of September 30, 2014 or 2013. All of our foreign cash and cash equivalents are readily convertible into U.S. dollars or other foreign currencies. Our

strategic plan does not require the repatriation of foreign cash in order to fund our operations in the U.S. and it is our current intention to permanently reinvest our foreign cash and cash equivalents outside of the U.S. If we were to repatriate foreign cash to the U.S., we may be required to accrue and pay U.S. taxes in accordance with applicable U.S. tax rules and regulations as a result of the repatriation. Our primary uses of cash are for:

    operating expenses;

    working capital requirements to fund the growth of our business;

    capital expenditures that primarily relate to IT equipment and our warehouse operations;

    debt service requirements for borrowings under the senior secured credit facilities (as defined below under "—Credit Facilities—Senior Secured Credit Facilities"); and

    strategic acquisitions.

        Generally, cash provided by operating activities has been adequate to fund our operations. Due to fluctuations in our cash flows and the growth in our operations, it may be necessary from time to time in the future to borrow under our revolving facility to meet cash demands. We anticipate that cash provided by operating activities, cash and cash equivalents and borrowing capacity under our revolving facility will be sufficient to meet our cash requirements for the next twelve months. As of September 30, 2014, we did not have any material capital expenditure commitments.

    Credit Facilities

    Senior Secured Credit Facilities

        On December 7, 2012, Wesco Aircraft and Wesco Aircraft Hardware Corp. entered into a credit agreement with Barclays Bank PLC, or Barclays, as administrative agent and collateral agent, Merrill Lynch, Pierce, Fenner & Smith Incorporated and Barclays, as joint lead arrangers, and the other lenders party thereto, to provide for (i) a $625.0 million term loan A facility, which we refer to as the term loan A facility, and (ii) a $200.0 million revolving credit facility, which we refer to as the revolving facility, which credit agreement was amended on February 28, 2014 by the First Amendment to Credit Agreement, or the Credit Agreement Amendment, to, among other things, provide an additional senior secured term loan B facility in the aggregate principal amount of $525.0 million, which we refer to as the term loan B facility, to finance, in part, the acquisition of Haas. We refer to the term loan B facility, together with the term loan A facility and the revolving facility, as the senior secured credit facilities. The Credit Agreement Amendment also (i) allowed for us to acquire Haas and for Wesco Aircraft Hardware Corp. to incur additional first lien indebtedness and corresponding liens to permit the incurrence of the term loan B facility and (ii) reset certain ratios with respect to the Consolidated Total Leverage Ratio covenant applicable to the term loan A facility and the revolving facility, as further described below.

        As of September 30, 2014, our outstanding indebtedness under the senior secured credit facilities was approximately $1,102.7 million, which consisted of (a) $550.8 million of indebtedness under the term loan A facility, (ii) $511.9 million of indebtedness under the term loan B facility and (iii) $40.0 million of indebtedness under the revolving facility. As of September 30, 2014, approximately $160.0 million was available for borrowing under the revolving facility without breaching any covenants contained in the agreements governing our indebtedness.

        The interest rate for the term loan A facility is based on our Consolidated Total Leverage Ratio (as such ratio is defined in the senior secured credit facilities) as determined in the most recently delivered financial statements, with the respective margins ranging from 1.75% to 2.50% for Eurocurrency loans and 0.75% to 1.50% for ABR loans. The term loan A facility amortizes in equal quarterly installments of 1.25% of the original principal amount of $625.0 million for the first year, escalating to quarterly installments of 2.50% of the original principal amount of $625.0 million by the fifth year, with the balance due at maturity on December 7, 2017.

Table of Contents

        The interest rate for the term loan B facility has a margin of 2.50% per annum for Eurocurrency loans (subject to a minimum Eurocurrency rate floor of 0.75% per annum) or 1.50% per annum for ABR loans (subject to a minimum ABR floor of 1.75% per annum). The term loan B facility amortizes in equal quarterly installments of 0.25% of the original principal amount of $525.0 million, with the balance due at maturity on February 28, 2021.

        The interest rate for the revolving facility is based on our Consolidated Total Leverage Ratio as determined in the most recently delivered financial statements, with the respective margins ranging from 1.75% to 2.50% for Eurocurrency loans and 0.75% to 1.50% for ABR loans. The revolving facility expires on December 7, 2017.

        The obligations under the senior secured credit facilities are guaranteed by us and all of our direct and indirect, wholly-owned, domestic restricted subsidiaries (subject to certain exceptions) and secured by a first lien on substantially all of our assets and the assets of our guarantor subsidiaries, including capital stock of subsidiaries (in each case, subject to certain exceptions).

        The senior secured credit facilities contain customary negative covenants, including restrictions on our and our restricted subsidiaries' ability to merge and consolidate with other companies, incur indebtedness, grant liens or security interests on assets, make acquisitions, loans, advances or investments, pay dividends, sell or otherwise transfer assets, optionally prepay or modify terms of any junior indebtedness or enter into transactions with affiliates. The senior secured credit facilities also require that our Consolidated Total Leverage Ratio not be in excess of 5.25 (with step-downs on such ratio during future periods) and that our Consolidated Net Interest Coverage Ratio (as such ratio is defined in the senior secured credit facilities) not be less than 2.25. As of September 30, 2014, our Consolidated Total Leverage Ratio was 4.14 and our Consolidated Net Interest Coverage Ratio was 7.05. Per the terms of the senior secured credit facilities, the preceding figures take into account the acquisition of Haas, which we acquired on February 28, 2014.

    Old Senior Secured Credit Facilities

        The old senior secured credit facilities, which were repaid on December 7, 2012 in connection with our entry into the senior secured credit facilities described above, consisted of a (i) $150.0 million revolving facility, which we refer to as the old revolving credit facility, (ii) $265.0 million term loan A facility, which we refer to as the old term loan A facility, and (iii) $350.0 million term loan B facility, which we refer to as the old term loan B facility.

        The interest rate for the old term loan A facility was based on our total consolidated net leverage ratio as determined in the most recently delivered financial statements, with the respective margins ranging from 2.25% to 3.25% for Eurocurrency loans and 1.25% to 2.25% for ABR loans. The old term loan A facility amortized in equal quarterly installments of 1.25% of the original principal amount of $265.0 million for the first year, escalating to quarterly installments of 3.75% of the original principal amount of $265.0 million by the fifth year, with the final payment due on April 7, 2016. The applicable margin for the old term loan B facility was based on our total consolidated net leverage ratio as determined in the most recently delivered financial statements, with the respective margins ranging from 2.75% to 3.00% for Eurocurrency loans and 1.75% to 2.00% for ABR loans. However, at no time could the Eurocurrency Rate or the ABR be less than 1.25%. The old term loan B facility amortized in equal quarterly installments of 0.25% of the original principal amount of $350.0 million. The remaining balance was due on April 7, 2017.

        The old revolving credit facility would have expired on April 7, 2016. The applicable margin was based on the total net leverage ratio as determined in the most recently delivered financial statements, with the respective margins ranging from 1.25% to 2.25% for the ABR loans and 2.25% to 3.25% for the Eurocurrency loans. From September 30, 2012 through December 7, 2012, we paid approximately $0.1 million in commitment fees for this line of credit.

        The obligations under the old senior secured credit facilities were guaranteed by us and all of our direct and indirect, wholly owned, domestic restricted subsidiaries (subject to certain exceptions) and secured by a first lien on substantially all of our assets and the assets of our guarantor subsidiaries, including capital stock of subsidiaries (in each case, subject to certain exceptions).

        The old senior secured credit facilities contained customary negative covenants, including restrictions on our and our restricted subsidiaries' ability to merge and consolidate with other companies, incur indebtedness, grant liens or security interests on assets, make acquisitions, loans, advances or investments, pay dividends, sell or otherwise transfer assets, optionally prepay or modify terms of any junior indebtedness or enter into transactions with affiliates. The old senior secured credit facilities also required that our Consolidated Total Leverage Ratio (as such ratio was defined in the old senior secured credit facilities) not be in excess of 4.00 (with step-downs on such ratio during subsequent periods) and that our Consolidated Interest Coverage Ratio (as such ratio was defined in the old senior secured credit facilities) not be less than 2.25.

        On June 13, 2012, Wesco Aircraft, Wesco Aircraft Hardware Corp., Barclays Bank PLC and the lenders party thereto entered into the First Amendment to Credit Agreement, which amended our old senior secured credit facilities to allow for (i) certain intercompany loans to be made to our restricted subsidiaries in order to facilitate the Interfast Acquisition and (ii) the Interfast Acquisition as a permitted investment.

    UK Line of Credit

        As of September 30, 2014, our subsidiary, Wesco Aircraft Europe, Ltd, has available a £7.0 million ($11.4 million based on the September 30, 2014 exchange rate) line of credit that automatically renews annually on October 1. The line of credit bears interest based on the base rate plus an applicable margin of 1.65%. The net outstanding borrowing under this line of credit was £0 as of September 30, 2014. As of September 30, 2014, the full £7.0 million was available for borrowing under the UK Line of Credit without breaching any covenants contained in the agreements governing our indebtedness.

This decrease was primarily the result of a $16.2 million use of cash related to accounts payable due to the timing of payments and inventory receipts, as well as $16.9 million use of cash related to income tax receivable as a result of the prior year receivable being depleted and consequently requiring payments to be made in fiscal 2014. Other drivers of the decrease in cash from operating activities were a $11.6 million increase in the change in accounts receivables driven by an increase in sales of $22.9 million, or 9.8%, during the fourth quarter of fiscal 2014 (exclusive of the Haas acquisition) as compared to the fourth quarter of fiscal 2013. Offsetting these decreases was a $17.6 million decrease in the change in inventory driven

by higher sales during the fourth quarter of fiscal 2014 as compared to the fourth quarter of fiscal 2013.

        Our operating activities generated $84.8 million of cash in the year ended September 30, 2013 an increase of $30.3 million, compared to the year ended September 30, 2012. This increase was primarily the result of a $12.6 million increase in net income, a $14.5 million favorable change in excess tax benefit related to restricted stock units and stock options exercised and a $54.0 million favorable change in income tax receivable. The income tax receivable of $45.3 million as of September 30, 2012 continues to be utilized to offset required tax payments, and as of September 30, 2013 the income tax receivable balance remains at $16.1 million. Offsetting these increases in cash generation was a $40.2 million increase in the change in inventory driven by an increase of 26% in inventory receipts during the year ended September 30, 2013 as compared to the year ended September 30, 2012. The increase in inventory receipts was driven by strategic purchases for future growth as well as to support the current growth in net sales of $125.4 million or 16.2% during the year ended September 30, 2013 as compared to the year ended September 30, 2012.

        Our accounts receivable balance as a percentage of net sales may fluctuate from quarter-to-quarter. These fluctuations are primarily driven by changes, from quarter-to-quarter, in (i) the timing of sales and (ii) the current average days sales outstanding. The completion of customer Contracts with accelerated payment terms can also contribute to these quarter-to-quarter fluctuations. Similarly, our accounts payable may fluctuate from quarter-to-quarter, which is primarily driven by the timing of purchases or payments made to our suppliers.

        Our allowance for doubtful accounts may also fluctuate from quarter-to-quarter. These fluctuations are primarily driven by changes in our accounts receivable balance, and can also be impacted by the repayment of amounts owed to us that had previously been categorized as bad debt.

    Investing Activities

        Our investing activities used approximately $571.5 million, $7.9 million and $136.4 million of cash in the years ended September 30, 2014, 2013 and 2012, respectively. The use of cash for investing activities during fiscal 2014 and 2012 was primarily comprised of $560.2 million used for the Haas acquisition in 2014 and CDN $133.5 million (or US $131.9 million) used for the Interfast Acquisition in 2012. The remaining amounts in fiscal 2014, in fiscal 2013 and in fiscal 2012 were mainly used for investments in various capital expenditures and to purchase property and equipment. Our purchases of property and equipment may vary from period to period due to the timing of the expansion of our business and the investment requirements to provide us with technology that allows us to better serve our customers.

    Financing Activities

        Our financing activities generated $543.0 million of cash in the year ended September 30, 2014. This was primarily due to $565.0 million of borrowings to fund the Haas acquisition. Other drivers were $10.2 million in excess tax benefit related to stock options exercised and $9.6 million of proceeds received in connection with the exercise of stock options. These amounts were partially offset by $10.2 million of financing fees paid in connection with the borrowings to fund the Haas acquisition, $30.3 million used to repay principal against the senior secured credit facilities and $1.3 million used to make principal payments under our capital lease obligations.

        Our financing activities used approximately $58.1 million of cash in the year ended September 30, 2013. These cash outflows were driven by the repayment of long term debt of $683.0 million, $7.3 million in financing fees related to new borrowings, and the payment of treasury stock of approximately $8.4 million. The cash outflow was partially offset by $625.0 million in new borrowings,

Table of Contents

$9.9 million related to proceeds from stock options exercised, and a $6.9 million excess tax benefit related to vested restricted stock units and stock options exercised.

        Our financing activities generated $96.9 million of cash in the year ended September 30, 2012. These cash inflows were driven by proceeds received in connection with the exercise of stock options of $7.4 million, $21.5 million of excess tax benefit related to vested restricted stock units and stock options exercised and proceeds of $95.0 million drawn from the revolving line of credit to partially fund the Interfast Acquisition. The cash generation was partially offset by $25.0 million used to repay principal against the senior secured credit facilities and $2.0 million used to make principal payments under our capital lease obligations.

ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISKS

        Our exposure to market risk consists of foreign currency exchange rate fluctuations, changes in interest rates and fluctuations in fuel prices.

    Foreign Currency Exposure

    Currency Translation

        During the years ended September 30, 2014 and 2013, approximately 20% and 23%, respectively, of our net sales were made by our foreign subsidiaries, and our total non-U.S. net sales represented approximately 43% and 42%, respectively, of our total net sales. As a result of these international operating activities, we are exposed to risks associated with changes in foreign exchange rates, principally exchange rates between the U.S. dollar, British pound, Canadian dollar, the Euro and the Mexican peso.

        The results of operations of our foreign subsidiaries are translated into U.S. dollars at the average exchange rate for each relevant period. This translation has no impact on our cash flow. However, as foreign exchange rates change, there are changes to the U.S. dollar equivalent of sales and expenses denominated in foreign currencies. Any adjustments resulting from the translation are recorded in accumulated other comprehensive income on our statements of changes in stockholders' equity. We do not consider the risk associated with exchange rate fluctuations to be material to our financial condition or results of operations. Our primary subsidiary in Canada now operates in U.S. dollars, which limits our risk associated with the exchange rate fluctuations for the Canadian dollar.

        A hypothetical 5% increase in the value of the British pound, the Euro, the Canadian dollar and the Mexican peso relative to the U.S. dollar would have resulted in an increase in our net income of approximately $1.2 million, less than $0.1 million, less than $0.1 million and less than $0.1 million, respectively, during fiscal 2014, and $1.2 million, less than $0.1 million, $0.2 million and $0, respectively, during fiscal 2013. A corresponding decrease would have resulted in a decrease in our net income of approximately $1.2 million, less than $0.1 million, less than $0.1 million and less than $0.1 million, respectively, during fiscal 2014, and $1.2 million, less than $0.1 million, $0.2 million and $0, respectively, during fiscal 2013.

    Currency Transactions

        Currency transaction exposure arises where actual sales and purchases are made by a company in a currency other than its own functional currency. During the year ended September 30, 2013, our subsidiary in the United Kingdom had sales in U.S. dollars and Euros of approximately $161.3 million and €12.5 million, respectively, and had purchases in U.S. dollars and Euros of approximately $97.5 million and €24.7 million, respectively. During the year ended September 30, 2014, our subsidiaries in the United Kingdom had sales in U.S. dollars and Euros of approximately $231.0 million and €9.5 million, respectively, and had purchases in U.S. dollars and Euros of approximately $128.0 million and €32.2 million, respectively. During the year ended September 30, 2013, our subsidiary in Canada had sales in Canadian dollars of approximately $7.0 million and had purchases in Canadian dollars of approximately $0.5 million. During the year ended September 30, 2014, our subsidiary in Canada had sales in Canadian dollars of approximately $4.8 million and had purchases in Canadian dollars of approximately $0.3 million. During the year ended September 30, 2014, our subsidiaries in Mexico and Israel, acquired in connection with the Haas acquisition, had purchases in U.S. dollars of approximately $8.0 million and purchases in Israeli shekels of approximately 20.4 million. To the extent possible, we structure arrangements where the purchase transactions are denominated in U.S. dollars in order to minimize near-term exposure to foreign currency fluctuations.

Table of Contents

        From September 30, 2011 to September 30, 2012, the U.S dollar strengthened slightly against the pound by $0.03 (from $1.61 to $1.58). From September 30, 2012 to September 30, 2013, the U.S dollar strengthened slightly against the pound by $0.02 (from $1.58 to $1.56). From September 30, 2013 to September 30, 2014, the U.S dollar weakened against the pound by $0.10 (from $1.56 to $1.66). A strengthening of the U.S. dollar means we realize a lesser amount of U.S. dollar revenue on sales that were denominated in British pounds, whereas a weakening of the U.S. dollar means we realize a greater amount of U.S. dollar revenue on sales that were denominated in British pounds. As a result of the slight movement of the U.S. dollar during fiscal 2012, 2013 and 2014, currency transactions did not have a material impact on our financial results during those periods. A hypothetical 5% increase in the value of the British pound relative to the U.S. dollar would have resulted in an increase in our net income of approximately $1.2 million and $1.2 million during fiscal 2013 and 2014, respectively, attributable to our foreign currency transactions. A corresponding decrease would have resulted in a decrease in our net income of approximately $1.2 million and $1.2 million during fiscal 2014 and 2013, respectively.

        We have historically entered into currency forward and option contracts to limit exposure to currency rate changes and will continue to monitor our transaction exposure to currency rate changes. Gains and losses on these contracts are deferred until the transaction being hedged is finalized. As of September 30, 2014, we had no outstanding currency forward and option contracts. We do not enter into currency forward and option contracts for trading or speculative purposes.

    Interest Rate Risk

        Our principal interest rate exposure relates to the senior secured credit facilities, which bear interest at a variable rate. See Part II, Item 7. "Management's Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Credit Facilities—Senior Secured Credit Facilities." If there is a rise in interest rates, our debt service obligations on the borrowings under the senior secured credit facilities would increase even though the amount borrowed remained the same, which would affect our results of operations, financial condition and liquidity. At our debt level and borrowing rates as of September 30, 2014, annual cash interest expense, including fees under our revolving facility, would have been approximately $32.9 million. If variable interest rates were to change by 1.0%, our interest expense would fluctuate approximately $9.3 million per year, without taking into account the effect of any hedging instruments.

        We periodically enter into interest rate swap agreements to manage interest rate risk on our borrowing activities. However, we are not currently a party to any swap agreements.

        We do not hold or issue derivative financial instruments for trading or speculative purposes.

    Fuel Price Risk

        Our principal direct exposure to increases in fuel prices is as a result of potential increased freight costs caused by fuel surcharges or other fuel cost-driven price increases implemented by the third-party package delivery companies on which we rely. We estimate that our annual freight costs (which consists of in-bound and out-bound freight-related costs, net of freight revenue) during fiscal 2014 and 2013 was approximately $18.1 million and $6.6 million, respectively, and as a result, we do not believe the impact of these potential fuel surcharges or fuel cost-driven price increases would have a material impact on our business, financial condition and results of operations. In addition, increases in fuel prices may have an indirect material adverse effect on our business, financial condition and results of operations, as such increases may contribute to decreased airline profitability and, as a result, decreased demand for new commercial aircraft that utilize the products we sell. See Part I, Item 1A. "Risk Factors—We may be materially adversely affected by high fuel prices." We do not use derivatives to manage our exposure to fuel prices.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Wesco Aircraft Holdings, Inc.

        In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of comprehensive income, stockholders' equity and cash flows present fairly, in all material respects, the financial position of Wesco Aircraft Holdings, Inc. and its subsidiaries at September 30, 2014 and September 30, 2013, and the results of their operations and their cash flows for each of the three years in the period ended September 30, 2014 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company did not maintain, in all material respects, effective internal control over financial reporting as of September 30, 2014, based on criteria established in Internal Control—Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) because a material weakness in internal control over financial reporting related to a lack of a sufficient complement of accounting and financial reporting personnel with an appropriate level of accounting knowledge and experience commensurate with the Company's financial reporting requirements existed as of that date. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis. The material weakness referred to above is described in Management's Report on Internal Control over Financial Reporting appearing under Item 9A. We considered this material weakness in determining the nature, timing, and extent of audit tests applied in our audit of the September 30, 2014 consolidated financial statements, and our opinion regarding the effectiveness of the Company's internal control over financial reporting does not affect our opinion on those consolidated financial statements. The Company's management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in management's report referred to above. Our responsibility is to express opinions on these financial statements and on the Company's internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

        A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

        Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

        As described in Management's Report on Internal Control over Financial Reporting, management has excluded Haas Group Inc. from its assessment of internal control over financial reporting as of September 30, 2014 because it was acquired by the Company in a purchase business combination during 2014. We have also excluded Haas from our audit of internal control over financial reporting. Haas Group Inc. is a wholly-owned subsidiary whose total assets and total revenues represent 11% and 26%, respectively, of the related consolidated financial statement amounts as of and for the year ended September 30, 2014.
