Introduction

Knife River is an aggregates-led construction materials and contracting services provider in the United States. Our 1.1 billion tons of aggregate reserves provide the foundation for our vertically integrated business strategy, with approximately 37 percent of our aggregates in 2023 being used internally to support value-added downstream products (ready-mix concrete and asphalt) and contracting services (heavy-civil construction, asphalt paving, concrete construction, site development and grading services, and in some segments the manufacturing of prestressed concrete products). We are strategically focused on being the provider of choice in mid-size, high-growth markets and are committed to our plan for continued growth and to delivering for our stakeholders — customers, communities, employees and stockholders — by executing on our four core values: People, Safety, Quality and the Environment.

We supply construction materials to customers from 14 states and also provide related contracting services, which are primarily to public-sector customers for the development and servicing of highways, local roads, bridges and other public-infrastructure projects. We have broad access to high-quality aggregates in most of our markets, which forms the foundation of our vertically integrated business model. We share resources, including plants, equipment and people, across our various locations to maximize efficiency. We also transport our products by truck, rail and barge to complete the vertical value chain, depending on the particular market. Our strategically located aggregate sites, ready-mix plants and asphalt plants, along with our fleet of ready-mix and dump trucks, enable us to better serve our customers. We believe our integrated and expansive business model is a strong competitive advantage that provides scale, efficiency and operational excellence for the benefit of customers, stockholders and the broader communities that we serve.

Knife River is organized into six operating segments: Pacific, Northwest, Mountain, North Central, South and Energy Services. These operating segments are used to determine the Company's reportable segments, Pacific, Northwest, Mountain, Central and Energy Services, which are based on our method of internal reporting and management of our business. Four of the reportable segments are aligned by key geographic areas due to the production of construction materials and related contracting services and one is based on product line. Each geographic segment offers a vertically integrated suite of products and services, including aggregates, ready-mix concrete, asphalt and contracting services, while the Energy Services segment, which has locations throughout our geographic footprint, produces and supplies liquid asphalt and related services, primarily for use in asphalt road construction. We also provide the details of Corporate Services, which includes accounting, legal, treasury, information technology, human resources and certain corporate expenses that support our operating segments. The internal reporting of these segments is defined based on the reporting and review process used by our chief executive and chief operating officers.

In the fourth quarter of 2023, we realigned our reportable segments to better support our operational strategies. The liquid asphalt and related services portion of the Pacific segment’s businesses are now reported under the Energy Services segment. In addition, the North Central and South operating regions have been aggregated into one reportable segment, Central. We also reallocated certain amounts to the operating segments that were previously reported within Corporate Services. All periods have been recast to conform with the revised presentation. For more information on the Company's business segments, see Note 14 of the Notes to Consolidated Financial Statements.

On May 31, 2023, the separation of Knife River from MDU Resources Group, Inc. ("MDU Resources") and its other businesses was completed and Knife River became an independent, publicly traded company ("Separation") listed on the New York Stock Exchange under the symbol "KNF". The Separation was completed as a tax-free spin-off for U.S. federal income tax purposes. As a result of the Separation, MDU Resources distributed shares representing approximately 90 percent of Knife River's outstanding common stock to holders of record of MDU Resources' common stock as of the close of business on May 22, 2023 ("Distribution"). In November 2023, MDU Resources disposed of all retained shares of Knife River.

Financial Statements

March 31, 2024 and 2023

(Unaudited)

Note 1 - Background

Knife River is a people-first construction materials and contracting services company. We provide construction materials and contracting services to build safe roads, bridges, airport runways, and other critical infrastructure needs, that connect people with where they want to go and with the supplies they need. Knife River is one of the leading providers of crushed stone and sand and gravel in the United States and operates across 14 states. We conduct our operations through five reportable segments: Pacific, Northwest, Mountain, Central and Energy Services.

In the fourth quarter of 2023, we realigned our reportable segments to better support our operational strategies. As a result, a portion of the Pacific segment’s businesses are now reported under the Energy Services segment. In addition, the North Central and South operating regions have been aggregated into one reportable segment, Central. We also reallocated certain amounts to the operating segments that were previously reported within Corporate Services. All periods have been recast to conform with the revised presentation. See Note 14 for additional information.

Separation from MDU Resources

On May 31, 2023, MDU Resources completed the previously announced separation of Knife River through the distribution of approximately 90 percent of the outstanding shares of common stock, par value $.01 per share, of Knife River to the stockholders of record of MDU Resources as of the close of business on May 22, 2023. MDU Resources retained approximately 10 percent of the outstanding shares of Knife River common stock. The Distribution was structured as a pro rata distribution of one share of Knife River common stock for every four shares of MDU Resources common stock. In November 2023, MDU Resources disposed of all 5,656,621 retained shares of Knife River common stock in an underwritten public offering. As a result of the Distribution, Knife River is now an independent public company and its common stock is listed under the symbol “KNF” on the New York Stock Exchange.

The Separation was completed pursuant to a separation and distribution agreement and other agreements with MDU Resources related to the Separation, including, but not limited to, a tax matters agreement, an employee matters agreement and a transition services agreement. For an interim period following the Separation, certain functions will continue to be provided by MDU Resources under a transition services agreement. For more information on the transition services agreement, see Note 16. We have incurred certain costs in establishing Knife River as an independent, publicly traded company and expect to incur ongoing additional costs associated with operating as an independent, publicly traded company.

All share and earnings per share information has been retroactively adjusted for all periods presented to reflect the Distribution.

Note 2 - Basis of presentation

The accompanying consolidated interim financial statements were prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Interim financial statements do not include all disclosures provided in annual financial statements and, accordingly, these financial statements should be read in conjunction with the Company's 2023 Annual Report on Form 10-K ("Annual Report"). The information is unaudited but includes adjustments that are, in the opinion of management, necessary for a fair presentation of the accompanying consolidated interim financial statements and are of a normal recurring nature.

Prior to the Separation, Knife River operated as a wholly owned subsidiary of Centennial Energy Holdings, Inc., a direct wholly owned subsidiary of MDU Resources and the direct parent company of Knife River prior to the spinoff ("Centennial") and an indirect, wholly owned subsidiary of MDU Resources and not as a stand-alone company. The accompanying consolidated financial statements and footnotes for the periods prior to the Separation were prepared on a "carve-out" basis using a legal entity approach in conformity with GAAP and were derived from the consolidated financial statements of MDU Resources as if Knife River operated on a stand-alone basis during these periods.

All revenues and costs, as well as assets and liabilities, directly associated with our business activities are included in the consolidated financial statements. In the periods prior to the Separation, the consolidated financial statements include expense allocations for certain functions provided by MDU Resources and Centennial, including, but not limited to certain general corporate expenses related to senior management, legal, human resources, finance and accounting, treasury, information technology, communications, procurement, tax, insurance and other shared services. These general corporate expenses are included in the Consolidated Statements of Operations within selling, general and administrative expenses and other income (expense). The amount allocated to Knife River was $4.9 million in selling, general and administrative expenses and $300,000 in other income for the three months ended March 31, 2023. These items were allocated on the basis of direct usage when identifiable, with the

Index

remainder principally allocated on the basis of percent of total capital invested or other allocation methodologies that were considered to be a reasonable reflection of the utilization of the services provided to the benefits received, including the following: number of employees paid and stated as cost per check; number of employees served; weighted factor of travel, managed units, national account spending, equipment and fleet acquisitions; purchase order dollars spent and purchase order line count; number of payments, vouchers or unclaimed property reports; labor hours; time tracked; and projected workload. The allocations may not, however, reflect the expenses we would have incurred as a stand-alone company for the periods presented. These costs also may not be indicative of the expenses that we will incur in the future or would have incurred if we had obtained these services from a third party.

Prior to the Separation, Knife River participated in Centennial’s centralized cash management program, including its overall financing arrangements. Knife River also had related-party note agreements in place with Centennial for the financing of its capital needs, which are reflected as related-party notes payable on the Consolidated Balance Sheet as of March 31, 2023. Interest expense in the Consolidated Statements of Operations, for the periods prior to the Separation, reflects the allocation of interest on borrowing and funding associated with the related-party note agreements. Upon the completion of the Separation, we implemented our own financing agreements with lenders. For additional information on the Knife River's current debt financing, see Note 12.

Related-party transactions between Knife River and MDU Resources or Centennial for general operating activities and intercompany debt have been included in the consolidated financial statements for periods prior to the Separation. Outstanding balances as of the periods presented were reflected on Consolidated Balance Sheets as “Due from related-party” or “Due to related-party” and “Related-party notes payable”. See Note 16 for additional information on related-party transactions.

Prior to the Separation, income tax expense and tax balances in the consolidated financial statements were calculated on a separate tax return basis. The separate tax return method applies the accounting guidance for income taxes to the stand-alone financial statements as if Knife River were a separate taxpayer and a standalone enterprise. We believe the assumptions supporting the allocation and presentation of income taxes on a separate return basis are reasonable. As a stand-alone entity, we will file tax returns on our own behalf, and tax balances and effective income tax rate may differ from the amounts reported in the historical periods.

Management has also evaluated the impact of events occurring after March 31, 2024, up to the date of issuance of these consolidated interim financial statements on May 7, 2024, that would require recognition or disclosure in the Consolidated Financial Statements.

Principles of consolidation

For all periods, the consolidated financial statements were prepared in accordance with GAAP and include the accounts of Knife River and its wholly owned subsidiaries. All intercompany accounts and transactions between the businesses comprising Knife River have been eliminated in the accompanying audited consolidated financial statements.

Use of estimates

The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosure of contingent assets and liabilities, at the date of the consolidated financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Estimates are used for items such as long-lived assets and goodwill; fair values of acquired assets and liabilities under the acquisition method of accounting; aggregate reserves; property depreciable lives; tax provisions; revenue recognized using the cost-to-cost measure of progress for contracts; expected credit losses; environmental and other loss contingencies; costs on contracting services contracts; actuarially determined benefit costs; asset retirement obligations; lease classification; present value of right-of-use assets and lease liabilities; and the valuation of stock-based compensation. These estimates are based on management’s best knowledge of current events, historical experience, actions that we may undertake in the future and on various other assumptions that are believed to be reasonable under the circumstances. As additional information becomes available, or actual amounts are determinable, the recorded estimates are revised. Consequently, operating results can be affected by revisions to prior accounting estimates.

Cash, cash equivalents and restricted cash

We consider all highly liquid investments with an original maturity of three months or less, when purchased, to be cash and cash equivalents. At March 31, 2024, the $170.7 million of cash, cash equivalents and restricted cash on the Consolidated Statements of Cash Flows is comprised of $128.4 million of cash and cash equivalents and $42.3 million of restricted cash. At March 31, 2023, the Company did not have any restricted cash. At December 31, 2023, the $262.3 million of cash, cash equivalents and restricted cash on the Consolidated Statements of Cash Flows is comprised of $219.3 million of cash and cash equivalents and $43.0 million of restricted cash. Restricted cash represents deposits held by our captive insurance company that is required by state insurance regulations to remain in the captive insurance company.

Seasonality of operations

Some of our operations are seasonal and revenues from, and certain expenses for, such operations may fluctuate significantly among quarterly periods, with lower activity in the winter months and higher activity in the summer months. Accordingly, the interim results for particular segments, and for Knife River as a whole, may not be indicative of results for the full fiscal year or other future periods.

Note 3 - New accounting standards

The following table provides a brief description of the accounting pronouncements applicable to Knife River and the potential impact on its consolidated financial statements and/or disclosures:


Standard	Description	Standard Effective Date	Impact on financial statements/disclosures
Recently issued Financial Accounting Standards Board (FASB) accounting standards updates ("ASU") not yet adopted
ASU 2023-07 - Improvements to Reportable Segment Disclosures	In November 2023, the FASB issued guidance on modifying the disclosure requirements to improve reportable segment disclosure requirements through enhanced disclosures about significant segment expenses. The guidance also expands the interim disclosure requirements. The guidance is to be applied on a retrospective basis to the financial statements and footnotes and early adoption is permitted.	Fiscal periods beginning after December 15, 2023 and interim periods beginning after December 31, 2024	The Company is currently evaluating the impact the guidance will have on its disclosures for the year ended December 31, 2024 and interim periods for fiscal year 2025.
ASU 2023-09 - Improvements to Income Tax Disclosures	In December 2023, the FASB issued guidance on modifying the disclosure requirements to increase transparency about income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information. The guidance is to be applied on a prospective basis to the financial statements and footnotes, however, retrospective adoption is also permitted. The guidance also permits early adoption.	Fiscal periods beginning after December 15, 2024	The Company is currently evaluating the impact the guidance will have on its disclosures for the year ended December 31, 2025.

Note 4 - Receivables and allowance for expected credit losses

Receivables consist primarily of trade and contract receivables for the sale of goods and services net of expected credit losses. A majority of our receivables are due in 30 days or less. The total balance of receivables past due 90 days or more was $12.6 million, $13.7 million and $16.7 million at March 31, 2024, March 31, 2023 and December 31, 2023, respectively. Receivables were as follows:


	March 31, 2024		March 31, 2023		December 31, 2023
	(In thousands)
Trade receivables	$	107,834	$	100,487	$	124,134

Less expected credit loss	6,077		5,822		6,168
Receivables, net	$	183,708	$	174,590	$	266,785

The Company's expected credit losses are determined through a review using historical credit loss experience; changes in asset specific characteristics; current conditions; and reasonable and supportable future forecasts, among other specific account data, and is performed at least quarterly. We develop and document our methodology to determine our allowance for expected credit losses. Risk characteristics used by management may include customer mix, knowledge of customers and general economic conditions of the various local economies, among others. Specific account balances are written off when management determines the amounts to be uncollectible. Management has reviewed the balance reserved through the allowance for expected credit losses and believes it is reasonable.

Supplies and parts	37,699		38,246		32,528
Total	$	375,783	$	373,215	$	319,623

Inventories are valued at the lower of cost or net realizable value using the average cost method. Inventories include production costs incurred as part of our aggregate mining activities. These inventoriable production costs include all mining and processing costs associated with the production of aggregates. Stripping costs incurred during the production phase, which represent costs of removing overburden and waste materials to access mineral deposits, are a component of inventoriable production costs.

Note 6 - Net loss per share

The calculation for basic and diluted earnings per share for any period presented prior to the Separation are based on the number of shares outstanding on May 31, 2023, the Separation and Distribution date. For periods prior to the Separation, it is assumed that there are no dilutive equity instruments as there were no Knife River stock-based awards outstanding at the time.

Basic net loss per share is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the applicable period. Diluted earnings per share is computed by dividing net income by the total of the weighted average number of shares of common stock outstanding during the applicable period, plus the effect of non-vested performance shares and restricted stock units. The Company's potentially dilutive securities have been excluded from the computation of diluted net loss per share as the effect would reduce the net loss per share and is considered antidilutive. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share is the same. Weighted average common shares outstanding is comprised of issued shares of 57,040,840 less shares held in treasury of 431,136. Basic and diluted earnings per share are calculated as follows, based on a reconciliation of the weighted-average common shares outstanding on a basic and diluted basis:

Note 8 - Revenue from contracts with customers

Revenue is recognized when a performance obligation is satisfied by transferring control over a product or service to a customer. Revenue includes revenue from the sales of construction materials and contracting services. Revenue is measured based on consideration specified in a contract with a customer and excludes any sales incentives and amounts collected on behalf of third parties. Knife River is considered an agent for certain taxes collected from customers. As such, we present revenues net of these taxes at the time of sale to be remitted to governmental authorities, including sales and use taxes. Revenue for construction materials is recognized at a point in time when delivery of the products has taken place. Contracting revenue is recognized over time using an input method based on the cost-to-cost measure of progress on a project.

Disaggregation

In the following tables, revenue is disaggregated by category for each segment and includes sales of materials to both third parties and internal customers. Due to consolidation requirements, the internal sales revenues must be eliminated against the construction materials product used in downstream materials and contracting services to arrive at the external operating revenues. We believe this level of disaggregation best depicts how the nature, amount, timing and uncertainty of revenue and cash flows are affected by economic factors. For more information on the Company’s reportable segments, see Note 14.

Note 9 - Uncompleted contracts

The timing of revenue recognition may differ from the timing of invoicing to customers. The timing of invoicing to customers does not necessarily correlate with the timing of revenues being recognized under the cost-to-cost method of accounting. Contracts from contracting services are billed as work progresses in accordance with agreed upon contractual terms. Generally, billing to the customer occurs contemporaneous to revenue recognition. A variance in timing of the billings may result in a contract asset or a contract liability. A contract asset occurs when revenues are recognized under the cost-to-cost measure of progress, which exceeds amounts billed on uncompleted contracts. Such amounts will be billed as standard contract terms allow, usually based on various measures of performance or achievement. A contract liability occurs when there are billings in excess of revenues recognized under the cost-to-cost measure of progress on uncompleted contracts. Contract liabilities decrease as revenue is recognized from the satisfaction of the related performance obligation.

The Company recognized $30.5 million in revenue for the three months ended March 31, 2024, which was previously included in contract liabilities at December 31, 2023. The Company recognized $20.3 million in revenue for the three months ended March 31, 2023, which was previously included in contract liabilities at December 31, 2022.

The Company recognized a net increase in revenues of $9.2 million and $3.6 million for the three months ended March 31, 2024 and 2023, respectively, from performance obligations satisfied in prior periods.

The remaining performance obligations, also referred to as backlog, include unrecognized revenues that we reasonably expect to be realized. These unrecognized revenues can include: projects that have a written award, a letter of intent, a notice to proceed, an agreed upon work order to perform work on mutually accepted terms and conditions and change orders or claims to the extent management believes additional contract revenues will be earned and are deemed probable of collection. The majority of our contracts for contracting services have an original duration of less than one year.

At March 31, 2024, the Company's remaining performance obligations were $959.5 million. We expect to recognize the following revenue amounts in future periods related to these remaining performance obligations: $891.0 million within the next 12 months or less; $59.2 million within the next 13 to 24 months; and $9.3 million in 25 months or more.

Note 11 - Fair value measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The fair value guidance establishes a hierarchy for grouping assets and liabilities, based on the significance of inputs. The estimated fair values of the Company's assets and liabilities measured on a recurring basis are determined using the market approach.

Index

Financial instruments measured at fair value on a recurring basis

We measure our investments in certain fixed-income and equity securities at fair value with changes in fair value recognized in income. We anticipate using these investments, which consist of insurance contracts, to satisfy our obligations under our unfunded, nonqualified defined benefit and defined contribution plans for the Company's executive officers and certain key management employees, and invests in these fixed-income and equity securities for the purpose of earning investment returns and capital appreciation. These investments, which totaled $27.1 million, $22.4 million and $24.9 million at March 31, 2024 and 2023, and December 31, 2023, respectively, are classified as investments on the Consolidated Balance Sheets. The net unrealized gains on these investments were $1.2 million and $827,000 for the three months ended March 31, 2024 and 2023, respectively. The change in fair value, which is considered part of the cost of the plan, is classified in other income on the Consolidated Statements of Operations.

The Company's assets measured at fair value on a recurring basis were as follows:

Index

The Company’s Level 2 money market funds are valued at the net asset value of shares held at the end of the period, based on published market quotations on active markets, or using other known sources including pricing from outside sources. The estimated fair value of the Company’s Level 2 insurance contracts is based on contractual cash surrender values that are determined primarily by investments in managed separate accounts of the insurer. These amounts approximate fair value. The managed separate accounts are valued based on other observable inputs or corroborated market data.

Though we believe the methods used to estimate fair value are consistent with those used by other market participants, the use of other methods or assumptions could result in a different estimate of fair value.

Nonfinancial instruments measured at fair value on a nonrecurring basis

We apply the provisions of the fair value measurement standard to our nonrecurring, non-financial measurements, including long-lived asset impairments. These assets are not measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain circumstances. We review the carrying value of our long-lived assets, excluding goodwill, whenever events or changes in circumstances indicate that such carrying amounts may not be recoverable.

The Company's long-term debt is not measured at fair value on the Consolidated Balance Sheets and the fair value is being provided for disclosure purposes only. The fair value was categorized as Level 2 in the fair value hierarchy and was based on discounted cash flows using current market interest rates. The estimated fair value of the Company's Level 2 long-term debt was as follows:

Note 14 - Business segment data

We focus on the vertical integration of our products and services by offering customers a single source for construction materials and related contracting services. We operate in 14 states across the United States through our operating segments: Pacific, Northwest, Mountain, North Central, South and Energy Services. These operating segments are used to determine the Company’s reportable segments, Pacific, Northwest, Mountain, Central and Energy Services, which are based on our method of internal reporting and management of our business. Four of the reportable segments are aligned by key geographic areas due to the production of construction materials and related contracting services and one is based on product line. Each segment is led by a segment manager who reports to the Company’s chief operating officer, who is also the Company's chief operating decision maker, along with the chief executive officer. The chief operating decision maker evaluates the performance of the segments and allocates resources to them based on earnings before interest, taxes, depreciation, depletion and amortization ("EBITDA").

In the fourth quarter of 2023, we realigned our reportable segments to better support our operational strategies. The liquid asphalt and related services portion of the Pacific segment's businesses are now reported under the Energy Services segment. In addition, the North Central and South operating regions have been aggregated into one reportable segment, Central. We also reallocated certain amounts to the operating segments that were previously reported within Corporate Services. All periods have been recast to conform with the revised presentation.

Each geographic segment offers a vertically integrated suite of products and services, including aggregates, ready-mix concrete, asphalt and contracting services, while the Energy Services segment produces and supplies liquid asphalt, primarily for use in asphalt road construction, and is a supplier to some of the other segments. Each geographic segment mines, processes and sells construction aggregates (crushed stone and sand and gravel); produces and sells asphalt; and produces and sells ready-mix concrete as well as vertically integrating its contracting services to support the aggregate-based product lines. Contracting services include heavy-civil construction, asphalt and concrete paving, and site development and grading. Although not common to all locations, the geographic segments also sell cement, merchandise and other building materials and related services.

Corporate Services represents the unallocated costs of certain corporate functions, such as accounting, legal, treasury, information technology, human resources and other corporate expenses that support the operating segments. We account for intersegment sales and transfers as if the sales or transfers were to third parties. The accounting policies applicable to each segment are consistent with those used in the audited consolidated financial statements.

Note 15 - Commitments and contingencies

The Company is party to claims and lawsuits arising out of its business and that of its consolidated subsidiaries, which may include, but are not limited to, matters involving property damage, personal injury, and environmental, contractual and statutory obligations. We accrue a liability for those contingencies when the incurrence of a loss is probable and the amount can be reasonably estimated. If a range of amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then the minimum of the range is accrued. We do not accrue liabilities when the likelihood that the liability has been incurred is probable but the amount cannot be reasonably estimated or when the liability is believed to be only reasonably possible or remote. For contingencies where an unfavorable outcome is probable or reasonably possible and which are material, we disclose the nature of the contingency and, in some circumstances, an estimate of the possible loss. Accruals are based on the best information available, but in certain situations management is unable to estimate an amount or range of a reasonably possible loss including, but not limited to when: (1) the damages are unsubstantiated or indeterminate, (2) the proceedings are in the early stages, (3) numerous parties are involved, or (4) the matter involves novel or unsettled legal theories.

At March 31, 2024 and 2023, and December 31, 2023, we accrued contingent liabilities as a result of litigation, which have not been discounted, of $1.2 million, $2.0 million and $873,000, respectively. At March 31, 2024 and 2023 and December 31, 2023, we also recorded corresponding insurance receivables of $400,000, $1.3 million and $42,000, respectively, related to the accrued liabilities. Most of these claims and lawsuits are covered by insurance, thus the Company's exposure is typically limited to its deductible amount. Management will continue to monitor each matter and adjust accruals as might be warranted based on new information and further developments. Management believes that the outcomes with respect to probable and reasonably possible losses in excess of the amounts accrued, net of insurance recoveries, while uncertain, either cannot be estimated or will not have a material effect upon the Company's financial position, results of operations or cash flows. Unless otherwise required by GAAP, legal costs are expensed as they are incurred.

Environmental matters

The Company is a party to claims for the cleanup of a superfund site in Portland, Oregon. There were no material changes to the environmental matters that were previously reported in the audited financial statements and notes included in the Company's 2023 Annual Report.

Guarantees

Knife River and certain of its subsidiaries have outstanding obligations to third parties where the Company has guaranteed their performance. These guarantees are related to contracts for contracting services and certain other guarantees. At March 31, 2024, the fixed maximum amounts guaranteed under these agreements aggregated to $11.5 million, all of which have no scheduled maturity date. Certain of the guarantees also have no fixed maximum amounts specified. There were no amounts outstanding under the previously mentioned guarantees at March 31, 2024.

Knife River and certain of its subsidiaries have outstanding letters of credit to third parties related to insurance policies, cement purchases and other agreements. At March 31, 2024, the fixed maximum amounts guaranteed under these letters of credit aggregated $21.0 million. At March 31, 2024, the amounts of scheduled expiration of the maximum amounts guaranteed under these letters of credit aggregate to $20.6 million in 2024, $332,000 in 2025, $0 in 2026 and $104,000 in 2027. There were no amounts outstanding under the previously mentioned letters of credit at March 31, 2024.

In the normal course of business, we have surety bonds related to contracts for contracting services, reclamation obligations and insurance policies of its subsidiaries. In the event a subsidiary of Knife River does not fulfill a bonded obligation, the Company would be responsible to the surety bond company for completion of the bonded contract or obligation. A large portion of the surety bonds are expected to expire within the next 12 months; however, we will likely continue to enter into surety bonds for our

Index

subsidiaries in the future. At March 31, 2024, approximately $902.3 million of surety bonds were outstanding, which were not reflected on the Consolidated Balance Sheet.

Company Overview

Knife River is a people-first construction materials and contracting services company. We provide construction materials and contracting services to build safe roads, bridges, airport runways and other critical infrastructure needs that connect people with where they want to go and with the supplies they need. We also champion a positive workplace culture by focusing on safety, training, inclusion, compensation and work-life balance.

Knife River is one of the leading providers of crushed stone and sand and gravel in the United States and operates through six operating segments across 14 states: Pacific, Northwest, Mountain, North Central, South and Energy Services. These operating segments are used to determine the Company's reportable segments and are based on our method of internal reporting and management of our business, as discussed in Note 14. The Company's reportable segments are: Pacific, Northwest, Mountain, Central and Energy Services. The geographic segments primarily provide aggregates, asphalt and ready-mix concrete, as well as related contracting services such as heavy-civil construction, asphalt paving, concrete construction, site development and grading. The Energy Services segment produces and supplies liquid asphalt and related services, primarily for use in asphalt road construction.

As an aggregates-led construction materials and contracting services provider in the United States, our 1.1 billion tons of aggregate reserves provide the foundation for a vertically integrated business strategy, with approximately 37 percent of our aggregates in 2023 being used internally to support value-added downstream products (ready-mix concrete and asphalt) and contracting services (heavy-civil construction, laydown, asphalt paving, concrete construction, site development and grading services, bridges and in some segments the manufacturing of prestressed concrete products). Our aggregate sites and associated asphalt and ready-mix plants are primarily in strategic locations near mid-sized, high-growth markets, providing us with a transportation advantage for our materials that supports competitive pricing and increased margins. We provide our products and services to both public and private markets, with public markets tending to be more stable across economic cycles, which helps offset the cyclical nature of the private markets.

Index

We provide various products and services and operate a variety of facility types, including aggregate quarries and mines, ready-mix concrete plants, asphalt plants and distribution facilities, in the following states:

•Pacific: Alaska, California and Hawaii

•Northwest: Oregon and Washington

•Mountain: Idaho, Montana and Wyoming

•Central: Iowa, Minnesota, North Dakota, South Dakota and Texas

•Energy Services: California, Iowa, Nebraska, South Dakota, Texas and Wyoming

Basis of Presentation

On May 31, 2023, Knife River became a stand-alone publicly traded company. Prior to the Separation, Knife River operated as a wholly owned subsidiary of Centennial Energy Holdings, Inc. ("Centennial") and an indirect, wholly owned subsidiary of MDU Resources Group, Inc. ("MDU Resources") and not as a stand-alone company. The accompanying historical consolidated financial statements and footnotes for the periods prior to the Separation were prepared on a “carve-out” basis using the legal entity approach in conformity with GAAP and were derived from the consolidated financial statements of MDU Resources as if Knife River operated on a stand-alone basis during these periods. For additional information related to the basis of presentation, see Note 2.

Prior to the Separation, Knife River participated in Centennial’s centralized cash management program, including its overall financing arrangements. Knife River also had related-party note agreements in place with Centennial for the financing of its capital needs, which are reflected as related-party notes payable on the Consolidated Balance Sheet at March 31, 2023. Interest expense in the Consolidated Statements of Operations, for the periods prior to the Separation, reflects the allocation of interest on the borrowings associated with the related-party note agreements. Upon the completion of the Separation, we implemented our own financing agreements with lenders. For additional information on the Knife River's current debt financing, see Note 12.

All intercompany balances and transactions between the businesses comprising Knife River have been eliminated in the accompanying consolidated financial statements.

Market Conditions and Outlook

Our markets remain resilient and construction activity remains generally strong despite ongoing general and economic challenges in the United States, such as higher interest rates and inflation. Our contracting services revenue averages approximately 80 percent each year being from public-sector projects, allowing us to better balance the cyclical nature of our private-sector customers. While we continued to experience inflationary pressures in the past year, price increases for our products and services have generally outpaced these increased costs. For more information on factors that may negatively impact Knife River's business, see the section entitled "Item 1A. Risk Factors" in Part I of the Company's 2023 Annual Report.

Backlog. Knife River’s contracting services backlog was as follows:


	March 31, 2024		March 31, 2023		December 31, 2023
	(In millions)
Pacific	$	92.9	$	75.1	$	51.2
Northwest	204.2		250.5		196.2
Mountain	383.2		366.1		256.7
Central	279.2		266.8		158.1

	$	959.5	$	958.5	$	662.2

Expected margins on backlog at March 31, 2024, were greater than the expected margins on backlog at March 31, 2023. Of the $959.5 million of expected backlog at March 31, 2024, we expect to complete approximately $891.0 million in the 12 months following March 31, 2024. Approximately 85 percent of our backlog at March 31, 2024 relates to publicly funded projects, including street and highway construction projects, which are driven primarily by public works projects for state departments of transportation. Further, there continues to be infrastructure development, as discussed in the following section on Public Funding, which is expected to provide bidding opportunities in our markets throughout 2024.

Period-over-period increases or decreases in backlog may not be indicative of future revenues, margins, net income or earnings before interest, taxes, depreciation, depletion and amortization ("EBITDA"). While we believe the current backlog of work remains firm, prolonged delays in the receipt of critical supplies and materials or continued increases to pricing, among other things, could result in customers seeking to delay or terminate existing or pending agreements and could reduce expected margins. See the section entitled “Item 1A. Risk Factors” in Part I of the Company's 2023 Annual Report for a list of factors that can cause revenues to be realized in periods and at levels that are different from originally projected.

Public Funding. Funding for public projects is dependent on federal and state funding, such as appropriations to the Federal Highway Administration. States have moved forward with allocating funds from the federal programs such as the Infrastructure Investment and Jobs Act, the American Rescue Plan Act, and more. In addition to federal funding, 12 out of the 14 states in which we operate have recently implemented funding mechanisms for public projects, including projects related to highways, airports and other public infrastructure. Within our 14 states of operation, state transportation departments have increased their 2024 spending authorizations by more than $9 billion, a 16 percent increase from 2023. We continue to monitor the implementation and impact of these legislative items and budget increases.

Profitability. Our management team continually monitors our margins and has been proactive in applying strategies to improve margins toward long-term profitability. In 2023, we began implementing EDGE initiatives and established teams to deliver training, assist with targeting higher-margin bidding opportunities across the regions and pursue growth opportunities. The process improvement team ("PIT crew") visited 10 of our largest locations in 2023, including quarries, asphalt plants and ready-mix plants. In 2024, the PIT crew has been expanded to extend its influence to more locations to standardize best practices. Our management team has also continued to evaluate growth opportunities, both through organic growth and acquisitions. During the first quarter of 2024, we advanced a number of our strategic investments, including upgraded plants to add capacity, a new ready-mix operation in our Central segment and the redeployment of plant assets into markets where they are expected to achieve higher returns. Also, on April 3, 2024, we acquired a small ready-mix operation in South Dakota. Our management team will continue to evaluate future growth opportunities that they believe will strategically align with our EDGE initiatives.

Knife River operates in geographically diverse and competitive markets, and strives to maximize efficiencies, including transportation costs and economies of scale, to maintain strong margins. Our margins can experience negative pressure from competition, as well as impacts from the volatility in the cost of raw materials, such as diesel fuel, gasoline, natural gas, liquid asphalt, cement and steel, with fuel and liquid asphalt costs often having the most significant impact on results. Many of these raw materials are subject to factors that are beyond our control, including global economic and political events and new and changing governmental regulations. The Energy Services segment is particularly susceptible to volatility in liquid asphalt costs, which can impact both cost of sales and revenues, for which we cannot reliably predict future pricing. Such volatility and inflationary pressures may have an impact on our margins, including fixed-price contracting services contracts that are particularly vulnerable to the variability of energy and material prices. We mitigate our exposure to these fluctuations by entering into various purchase commitments, as well as by generally including terms in our contracting services agreements that provide for price adjustments related to variations in raw materials costs.

Index

Our operations can also be significantly impacted by both favorable and unfavorable weather conditions. Unseasonably wet and/or cold weather in the states where we operate can delay the start or cause an early end to the construction season or cause temporary delays on specific projects, while unseasonably dry or warm weather in the states where we operate can allow for a lengthened construction season or allow for an earlier start on specific projects. Either of these conditions can impact both our construction materials sales and contracting services revenues. Other variables that can impact margins include the timing of project starts or completions, pre-construction season activities including equipment repair and maintenance costs or equipment mobilization, and declines or delays in new and existing projects due to the cyclical nature of the construction industry. Accordingly, operating results in any particular period may not be indicative of the results that can be expected for any other period.

Workforce. As a people-first company, we continually take steps to address the challenge of recruitment and retention of our employees. We continue to deploy significant resources to attract, develop and retain qualified and diverse talent. As the United States continues to face shortages in the availability of individuals to fill construction careers, we have taken significant steps to showcase construction as a career of choice. We own and operate a state-of-the-art training facility, the Knife River Training Center, which is used corporate-wide to enhance the skills of both our new and existing employees through both classroom education and hands-on experience. One of the most popular courses at the Knife River Training Facility is the commercial driver's license training, which is helping to address some labor shortages and trends.

Revenue includes revenue from the sale of construction materials and contracting services. Revenue for construction materials is recognized at a point in time when delivery of the products has taken place. Contracting services revenue is recognized over time using an input method based on the cost-to-cost measure of progress on a project.

Cost of revenue includes all material, labor and overhead costs incurred in the production process for Knife River's products and services. Cost of revenue also includes depreciation, depletion and amortization attributable to the assets used in the production process.

Gross profit includes revenue less cost of revenue, as defined above, and is the difference between revenue and the cost of making a product or providing a service, before deducting selling, general and administrative expenses, income taxes and interest expense.

Selling, general and administrative expenses include the costs for estimating, bidding and business development, as well as costs related to corporate and administrative functions. Selling expenses can vary depending on the volume of projects in process and the number of employees assigned to estimating and bidding activities. Other general and administrative expenses include outside services; information technology; depreciation and amortization; training, travel and entertainment; office supplies; allowance for expected credit losses; gains or losses on the sale of assets; and other miscellaneous expenses.

Other income (expense) includes net periodic benefit costs for the Company’s benefit plan expenses, other than service costs; interest income; realized and unrealized gains and losses on investments for the Company’s nonqualified benefit plans; earnings or

Index

losses on joint venture arrangements; and other miscellaneous income or expenses, including income and expenses related to the transition services agreement with MDU Resources.

Income tax (benefit) expense consists of corporate income taxes related to the net income of the Company. Income taxes are presented at the corporate services level and not at the individual segments. The effective tax rate can be affected by many factors, including changes in tax laws, regulations or rates, new interpretations of existing laws or regulations and changes to the Company's overall levels of income before income tax.

The discussion that follows focuses on the key financial measures the Company uses to evaluate the performance of its business, which include revenue, gross profit, gross margin, EBITDA and EBITDA margin. Gross margin is calculated by dividing gross profit by revenue. Gross margin reflects the percentage of revenue earned in comparison to cost. EBITDA and EBITDA margin are non-GAAP financial measures. For more information and reconciliations to the nearest GAAP measures, see the section entitled "Non-GAAP Financial Measures."

Three Months Ended March 31, 2024, Compared to Three Months Ended March 31, 2023

Revenue

Revenue improved $21.7 million as increased pricing added $24.5 million in revenue across all regions and most product lines, supported by demand and EDGE-related pricing initiatives, offset in part by lower aggregates and ready-mix sales volumes as a result of project timing and the absence of a large data center project in 2023. Contracting services revenues were higher as a result of improved weather conditions and availability of winter work, which provided an earlier start to the construction season and fewer delays.

Gross profit and gross margin

Gross profit improved $2.4 million and gross margin improved 70 basis points. Contracting services margins improved across all regions, partly due to improved weather conditions, higher bid margins and job productivity gains in some regions. Overall aggregate margins also improved due to pricing. These increases were mostly offset by higher expenses as operations were able to begin pre-construction season activities earlier, which includes maintenance-related work, plant mobilization and crew training.

Selling, general and administrative expenses

Selling, general and administrative expenses increased $11.5 million. As a result of the Separation, we experienced recurring costs as a publicly traded company of $9.5 million, including payroll-related costs of $5.6 million, largely due to additional staff and stock-based compensation expenses for the management team and board of directors: information technology costs of $1.4 million; professional services of $1.3 million; fees of $520,000 primarily related to fees on new debt issued in conjunction with the Separation; and insurance costs of $395,000. These recurring costs were partially offset by a reduction in general corporate expenses from MDU Resources of $4.6 million, as discussed in Note 2. Also, as part of the Separation, we incurred additional one-time costs of $1.5 million, primarily related to insurance costs and the transition services agreement with MDU Resources. Further contributing to the higher selling, general and administrative costs were increased payroll-related costs of $4.7 million throughout the segments and lower gains on asset sales in the Mountain segment, offset in part by higher gains on assets sales in the Northwest segment.

Interest expense

Interest expense increased $4.4 million due primarily to higher average interest rates as a result of the Company settling related-party notes payable as part of the Separation and entering into new debt arrangements with higher interest rates.

Index

Other income

Other income improved $2.8 million due to increased interest income on higher cash balances over the prior period.

Income tax benefit

Income tax benefit increased $4.4 million corresponding with the higher net loss before income taxes.

Business Segment Financial and Operating Data

A discussion of key financial data from Knife River’s business segments follows. Knife River provides segment level information by revenue, gross profit, gross margin, EBITDA and EBITDA margin as these are the measures of profitability used by our management to assess operational results. EBITDA and EBITDA margin are non-GAAP financial measures. For more information and reconciliations to the nearest GAAP measure, see the section entitled "Non-GAAP Financial Measures.”

In the fourth quarter of 2023, we realigned our reportable segments to better support our operational strategies. Based on how the chief operating decision maker manages the Company, the reportable segments are: Pacific, Northwest, Mountain, Central and Energy Services. The liquid asphalt and related services portion of the Pacific segment’s businesses are now reported under the Energy Services segment. In addition, the North Central and South operating regions have been aggregated into one reportable segment, Central. We also provide the details of Corporate Services, which includes accounting, legal, treasury, information technology, human resources and certain corporate expenses that support our operating segments. As a result of the segment changes, we reallocated certain amounts to the operating segments that were previously reported within Corporate Services. All periods have been recast to conform with the revised presentation.

Three Months Ended March 31, 2024, Compared to Three Months Ended March 31, 2023

Revenue

Revenue improved $12.7 million, largely the result of higher contracting services revenues in northern California driven by improved weather conditions compared to 2023, which provided an earlier start to the construction season. Increased pricing for most product lines also contributed $6.3 million to the revenue improvement. Ready-mix concrete volumes also increased as a result of strong residential demand in northern California driven by the earlier start to the construction season and market improvements in Hawaii. Partially offsetting these increases were lower aggregate sales volumes of $2.9 million, largely due to less work in the quarter.

Index

Gross profit and gross margin

Gross profit decreased $600,000 and gross margin decreased 190 basis points. Gross profit was negatively impacted by higher repair and maintenance costs as the segment had an earlier start preparing for the construction season compared to the prior year. Also impacting gross profit were lower margins on aggregates of $1.1 million, primarily related to the timing of production costs and lower third-party sales in California. Partially offsetting the decreases were improved margins on ready-mix concrete as price increases of $850,000 mostly outpaced increased costs, as well as improved contracting services margins due to the earlier start to the construction season.

EBITDA and EBITDA margin

EBITDA decreased $800,000 and EBITDA margin decreased 110 basis points. The decrease was the result of decreased gross profit as discussed above, increased labor and labor-related costs due to a restructuring in Hawaii, and increased bad debt expense of $200,000.

Three Months Ended March 31, 2024, Compared to Three Months Ended March 31, 2023

Revenue

Revenue improved $4.4 million, largely driven by contracting services revenues benefiting from more available winter work in certain markets, as well as price increases contributing $7.6 million of additional revenue across most of the region for ready-mix concrete and aggregates. Additional asphalt volumes of $1.6 million, partially resulting from increased public agency, commercial and residential demand, also contributed to higher revenues. Partially offsetting these increases were lower ready-mix concrete sales volumes of $6.5 million as a result of reduced demand in the quarter, as well as lower aggregate sales volumes of $6.4 million driven by the absence of a large data center project in the prior year.

Gross profit and gross margin

Gross profit improved $3.6 million and gross margin improved 250 basis points mainly due to increased margins on contracting services work. Also contributing to the improvement was higher gross profit on aggregates, largely the result of increased pricing outpacing costs, and higher gross profit on asphalt of $1.4 million driven by lower material costs.

Index

EBITDA and EBITDA margin

EBITDA improved $6.1 million and EBITDA margin improved 470 basis points, mainly due to higher gross profit margins discussed above, higher gains on asset sales of $1.0 million and lower selling, general and administrative expenses.

Revenue

Revenue decreased $800,000 as contracting services throughout Montana and Wyoming were negatively impacted by the timing of public agency work and aggregates sales volumes declined in Idaho due to project timing. Further impacting revenues were decreased ready-mix concrete sales volumes in Montana resulting from reduced residential demand in eastern Montana, along with the timing of customer projects throughout Montana. These decreases were partially offset by increased pricing for aggregates and ready-mix concrete of $3.6 million, higher aggregates sales volumes in Wyoming due to increased sales to wind energy and solar projects and an increase in contracting services in Idaho of $1.4 million due to change order work.

Gross profit and gross margin

Gross profit decreased $700,000 and gross margin decreased 120 basis points. Gross profit was negatively impacted by higher equipment mobilization and repair and maintenance costs to prepare for an earlier start of the construction season. Partially offsetting the decrease was an increase in contracting services gross profit due to change order work and cost savings on projects, as well as higher aggregates gross profit due to lower production costs.

EBITDA and EBITDA margin

EBITDA decreased $2.3 million and EBITDA margin decreased 390 basis points resulting from the decreased gross margin discussed above, in addition to the absence of asset sale gains of $2.0 million in the prior year.

Revenue

Revenue improved $3.4 million, the largest driver being increased pricing of $5.3 million across all core product lines with most of the impact realized in the south region. Partially offsetting the increase was lower contracting services revenues during the quarter, primarily related to less paving work in the south region and decreased subcontract work due to timing in the north central region.

Gross profit and gross margin

Gross profit decreased $700,000 and gross margin decreased 20 basis points. The decrease was primarily attributed to an earlier start to pre-construction season activities in the north central region, including maintenance-related work, plant mobilization and crew training. Partially offsetting this decrease was improved margins on contracting services work as both regions continue to implement EDGE-related initiatives. Also offsetting the decrease was higher aggregate gross profit in the south region as increased pricing of $2.5 million more than offset increased costs.

EBITDA and EBITDA margin

EBITDA decreased $1.8 million and EBITDA margin decreased 140 basis points, as a direct result of the lower gross profit, as well as increased selling, general and administrative costs of $1.7 million, largely related to labor and training.

Revenue

Revenue improved $3.4 million largely the result of strong markets in California and Texas, which benefited from favorable weather and higher demand, more than offsetting lower volumes in Wyoming due to project timing and the absence of throughput volumes when compared to the prior year.

Gross profit and gross margin

Gross profit improved $500,000 and gross margin improved 940 basis points, which was driven by lower cost of materials and lower maintenance costs in the quarter.

EBITDA and EBITDA margin

EBITDA improved $500,000 and EBITDA margin improved 1,230 basis points, which was related to increased gross profit previously discussed.

Corporate Services and Eliminations

Corporate Services includes all expenses related to the corporate functions of the Company, as well as insurance activity at our captive insurer; interest expense on a majority of the Company's long-term debt; interest income; and unrealized gains or losses on investments for the Company's nonqualified benefit plans.

During the first quarter of 2024, Corporate Services contributed negative EBITDA of $12.7 million, or $8.2 million less EBITDA compared to the prior year. The decrease was largely due to higher selling, general and administrative costs of $8.3 million primarily resulting from additional costs incurred as a publicly traded company, as well as costs related to the Separation from MDU Resources.

As a result of the Separation, we experienced recurring costs of $9.5 million, including payroll-related costs of $5.6 million, largely due to additional staff and stock-based compensation expense for the management team and board of directors; information technology costs of $1.4 million; professional services of $1.3 million; fees of $520,000 primarily related to fees on new debt issued in conjunction with the Separation; and insurance costs of $395,000. These recurring costs were partially offset by a reduction in general corporate expenses from MDU Resources of $4.6 million, as further discussed in Note 2. Also, as part of the Separation, we incurred additional one-time costs of $1.5 million primarily related to insurance costs, information technology costs and the transition services agreement with MDU Resources.

Index

Further increasing selling, general and administrative expenses were higher health care costs in 2024 of $1.7 million as prior year claims for 2023 were paid from the MDU Resources health and welfare trust therefore reducing the Company's expense in 2023. Partially offsetting these increased costs were improved returns on the Company's nonqualified benefit plan investments of $320,000.

Liquidity and Capital Resources

At March 31, 2024, Knife River had cash and cash equivalents of $128.4 million, working capital of $520.5 million and borrowing capacity of $329.0 million on our revolving credit agreement. Working capital is calculated as current assets less current liabilities. As of March 31, 2024, we believe Knife River has sufficient liquid assets, cash flows from operations and borrowing capacity to meet its financial commitments, debt obligations and anticipated capital expenditures for at least the next 12 months.

Given the seasonality of our business, we typically experience significant fluctuations in working capital needs and balances throughout the year. Working capital requirements generally increase in the first half of the year as we build up inventory and focus on preparing our equipment, facilities and crews for our construction season. Working capital levels then decrease as the construction season winds down and we collect on receivables.

Knife River’s ability to fund its cash needs will depend on the ongoing ability to generate cash from operations and obtain debt financing with competitive rates. Knife River relies on access to capital markets as sources of liquidity for capital requirements not satisfied by cash flows from operations, particularly in the first half of the year due to the seasonal nature of the industry. Our principal uses of cash in the future will be to fund our operations, working capital needs, capital expenditures, repayment of debt and strategic business development transactions.

Capital expenditures

We currently estimate total 2024 capital expenditures to be between $170 million to $180 million for both maintenance and growth projects and excludes acquisitions. As of March 31, 2024, $43.7 million has been spent on routine replacement and maintenance of vehicles and equipment, building improvements, a liquid asphalt expansion project and redistribution of plant assets. These expenditures were funded by internally generated cash.

Our management team remains focused on organic and acquisition growth opportunities that they believe align with our EDGE strategies, which includes the acquisition of a small ready-mix operation in South Dakota on April 3, 2024. While the 2024 budgeted capital expenditures includes some organic growth projects, future acquisitions and other growth opportunities that support our EDGE strategy would be incremental to the outlined capital program; however, these opportunities are dependent upon economic and other competitive conditions. It is anticipated that capital expenditures for 2024 will be funded by various sources, including internally generated cash and debt.

This reduction in cash usage in 2024 was primarily the result of collections on higher receivables balances in the last quarter of 2023 and the first quarter of 2024, offset in part by higher liquid asphalt inventory balances. In addition, the timing of insurance costs associated with the captive insurer had a positive impact on cash.

Index

Material cash requirements

There were no material changes in the Company's contractual obligations related to estimated interest payments, purchase commitments, asset retirement obligations, uncertain tax positions and minimum funding requirements for its defined benefit plans for 2024 from those reported in the 2023 Annual Report. For more information on the Company's contractual obligations on long-term debt, operating leases and purchase commitments, see Part II, Item 7 in the 2023 Annual Report.

Our material short-term and long-term cash requirements include repayment of third-party long-term debt and related interest payments, related-party notes payable and related interest payments, payments on operating lease agreements, payments of obligations on purchase commitments and asset retirement obligations.

Non-GAAP Financial Measures

The Business Segment Financial and Operating Data includes financial information prepared in accordance with GAAP, as well as EBITDA, EBITDA margin, Adjusted EBITDA and Adjusted EBITDA margin financial measures. These non-GAAP financial measures, including those measures by segment, as applicable, are considered non-GAAP measures of financial performance. These non-GAAP financial measures are not measures of financial performance under GAAP. The items excluded from these non-GAAP financial measures are significant components in understanding and assessing financial performance. Therefore, these non-GAAP financial measures should not be considered substitutes for the applicable GAAP metric.

EBITDA, EBITDA margin, Adjusted EBITDA and Adjusted EBITDA margin are most directly comparable to the corresponding GAAP measures of net income and net income margin. We believe these non-GAAP financial measures, in addition to corresponding GAAP measures, are useful to investors by providing meaningful information about operational efficiency compared to our peers by excluding the impacts of differences in tax jurisdictions and structures, debt levels and capital investment. We believe Adjusted EBITDA and Adjusted EBITDA margin are useful performance measures because they allow for an effective evaluation of our operating performance by excluding stock-based compensation and unrealized gains and losses on benefit plan investments as they are considered non-cash and not part of our core operations. We also exclude the one-time, non-recurring costs associated with the Separation as those are not expected to continue. We believe EBITDA and Adjusted EBITDA assist rating agencies and investors in comparing operating performance across operating periods on a consistent basis by excluding items management does not believe are indicative of the Company's operating performance. Additionally, EBITDA and Adjusted EBITDA are important financial metrics for debt investors who utilize debt to EBITDA and debt to Adjusted EBITDA ratios. We believe EBITDA and EBITDA margin, including those measures by segment, are useful performance measures because they provide clarity as to the operational results of the Company. Our management uses these non-GAAP financial measures in conjunction with GAAP results when evaluating our operating results internally and calculating employee incentive compensation.

EBITDA is calculated by adding back income taxes, interest expense (net of interest income) and depreciation, depletion and amortization expense to net income. EBITDA margin is calculated by dividing EBITDA by revenues. Adjusted EBITDA is calculated by adding back unrealized gains and losses on benefit plan investments, stock-based compensation and one-time Separation costs, to EBITDA. Adjusted EBITDA margin is calculated by dividing Adjusted EBITDA by revenues. These non-GAAP financial measures are calculated the same for both the segment and consolidated metrics and should not be considered as alternatives to, or more meaningful than, GAAP financial measures such as net income or net income margin, and are intended to be helpful supplemental financial measures for investors’ understanding of our operating performance. Our non-GAAP financial measures are not standardized; therefore, it may not be possible to compare these financial measures with other companies’ EBITDA, EBITDA margin, Adjusted EBITDA and Adjusted EBITDA margin measures having the same or similar names.

Index

The following information reconciles segment and consolidated net income (loss) to EBITDA and Adjusted EBITDA and provides the calculation of EBITDA margin and Adjusted EBITDA margin. Interest expense, net, is net of interest income that is included in other income (expense) on the Consolidated Statements of Operations.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

The Company is exposed to the impact of market fluctuations associated with interest rates and commodity prices. We have policies and procedures to assist in controlling these market risks and from time to time has utilized derivatives to manage a portion of its risk.

Interest rate risk

As of March 31, 2024, the Company had $269.8 million in term loans outstanding which bear interest at a variable rate. As of March 31, 2024, the rate in effect was 7.19 percent, therefore, a hypothetical increase of 1.00 percent to the interest rate at March 31, 2024 would increase the all-in rate to 8.19 percent, the effect of which would increase the Company's interest expense by $2.7 million over the next 12 months based on the balances outstanding for these borrowings as of March 31, 2024.

At March 31, 2024, the Company had no outstanding interest rate hedges.

Commodity price risk

There were no material changes to commodity price risk faced by the Company from those reported in the 2023 Annual Report.

Evaluation of disclosure controls and procedures

The term "disclosure controls and procedures" is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. The Company's disclosure controls and other procedures are designed to provide reasonable assurance that information required to be disclosed in the reports that the Company files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms. The Company's disclosure controls and other procedures are designed to provide reasonable assurance that information required to be disclosed is accumulated and communicated to management, including the Company's chief executive officer and chief financial officer, to allow timely decisions regarding required disclosure. The Company's management, with the participation of the Company's chief executive officer and chief financial officer, has evaluated the effectiveness of the Company's disclosure controls and other procedures as of the end of the period covered by this report. Based upon that evaluation, the chief executive officer and the chief financial officer have concluded that, as of the end of the period covered by this report, such controls and procedures were effective at a reasonable assurance level.

Changes in internal controls
