CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS
This Quarterly Report on Form 10-Q includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that relate to future events, our future operations or financial performance, or our plans, strategies and prospects. These statements are based on the beliefs and assumptions of our management team. Although we believe that our plans, intentions and expectations reflected in or suggested by these forward-looking statements are reasonable, we cannot assure that we will achieve or realize these plans, intentions or expectations. Forward-looking statements are inherently subject to risks, uncertainties and assumptions. Generally, statements that are not historical facts, including statements concerning possible or assumed future actions, business strategies, events or performance, are forward-looking statements. The actual results may differ from its expectations, estimates, and projections and, consequently, you should not rely on these forward-looking statements as predictions of future events. Words such as “expect,” “estimate,” “project,” “budget,” “forecast,” “anticipate,” “intend,” “plan,” “may,” “will,” “could,” “should,” “believes,” “predicts,” “potential,” “continue,” and similar expressions (or the negative versions of such words or expressions) are intended to identify such forward-looking statements. These forward-looking statements include, without limitation, our expectations with respect to future performance and development and commercialization of products and services. The forward-looking statements are based on projections prepared by, and are the responsibility of, management and involve significant risks and uncertainties that could cause the actual results to differ materially from those discussed in the forward-looking statements. Most of these factors are outside our control and are difficult to predict. Forward-looking statements contained in this Quarterly Report on Form 10-Q include, but are not limited to, statements about:
the impact of international conflicts, pandemics or epidemics on our business;
the inability to maintain the listing of our Class A common stock on The Nasdaq Stock Market LLC;
changes in applicable laws or regulations;
our ability to raise financing in the future;
the success, cost and timing of our product development and commercialization activities;
the commercialization and adoption of our existing products, including the Platinum® protein sequencing instrument, and the success of any product we may offer in the future;
our ability to obtain and maintain regulatory approval for our products, and any related restrictions and limitations of any approved product;
our ability to identify, in-license or acquire additional technology;
our ability to maintain our existing lease, license, manufacture and supply agreements;
our ability to compete with other companies currently marketing or engaged in the development or commercialization of products and services that serve customers engaged in proteomic analysis, many of which have greater financial and marketing resources than us;
the size and growth potential of the markets for our products and services, and our ability to serve those markets once commercialized, either alone or in partnership with others;
our estimates regarding future expenses, future revenue, capital requirements and needs for additional financing; and

QUANTUM-SI INCORPORATED
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(in thousands, except share and per share amounts)
(Unaudited)
Note 1. Organization and Description of Business
Quantum-Si Incorporated (including its subsidiaries, the “Company” or “Quantum-Si”) was incorporated in Delaware on June 10, 2020 as HighCape Capital Acquisition Corp. (“HighCape”). The Company’s legal name became Quantum-Si Incorporated following a business combination on June 10, 2021 between the Company and Q-SI Operations Inc. (formerly Quantum-Si Incorporated) (the “Business Combination”), which was founded in 2013.
The Company is an innovative life sciences company with the mission of transforming single-molecule analysis and democratizing its use by providing researchers and clinicians access to the proteome, the set of proteins expressed within a cell. The Company has developed a proprietary universal single-molecule detection platform that the Company is first applying to proteomics to enable Next-Generation Protein Sequencing (“NGPS”), the ability to sequence proteins in a massively parallel fashion (rather than sequentially, one at a time), and can be used for the study of nucleic acids. The Company’s platform is currently comprised of the Platinum® NGPS instrument, the Platinum Analysis Software service, reagent kits and semiconductor chips for use with its instruments.
Liquidity and Capital Resources
The Company has historically financed its operations primarily with proceeds from the issuance of equity to private investors, as well as with the proceeds received from the closing of the Business Combination on June 10, 2021. The Company has incurred significant losses and negative cash flows from operations in all periods since inception and had an accumulated deficit of $563.5 million as of September 30, 2024. The Company has incurred significant operating losses, including net losses of $67.9 million and $73.9 million for the nine months ended September 30, 2024 and 2023, respectively. As of September 30, 2024, the Company had cash, cash equivalents and investments in marketable securities of $196.3 million. Management believes that the Company’s current cash, cash equivalents and marketable securities, together with revenue from the sales of its products and services, will be sufficient to fund its planned operations for at least the next twelve months from the date of the issuance of the accompanying Condensed Consolidated Financial Statements.

Until such time as the Company can generate significant revenue from product sales, if ever, it expects to finance its operations through private and public equity offerings, debt financings, and/or potential future collaboration, license and development agreements. However, there can be no assurance that the Company will be able to complete any such transactions on acceptable terms or otherwise, and the Company may be unable to obtain sufficient additional capital when needed. The inability to raise capital as and when needed would have a negative impact on the Company’s financial condition and its ability to pursue its business strategy. The Company will need to generate significant revenue to achieve profitability and it may never do so.
Note 2. Summary of Significant Accounting Policies
Basis of Presentation and Principles of Consolidation
The accompanying Condensed Consolidated Financial Statements include the accounts of the Company and have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the accounting disclosure rules and regulations of the Securities and Exchange Commission (the “SEC”). All intercompany transactions are eliminated.
These Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023. The Condensed Consolidated Balance Sheet as of December 31, 2023 included herein was derived from the audited Consolidated Financial Statements as of that date, but does not include all disclosures, including certain notes required by U.S. GAAP, on an annual reporting basis.
In the opinion of management, the accompanying Condensed Consolidated Financial Statements reflect all normal recurring adjustments necessary to fairly state the financial position, results of operations, and cash flows for the interim
8

periods. The results for the three and nine months ended September 30, 2024 are not necessarily indicative of the results to be expected for any subsequent quarter, the year ending December 31, 2024, or any other period.
There have been no material changes to the Company’s significant accounting policies as described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.
Global Developments
Throughout 2023, various central banks around the world, including the Federal Reserve in the United States, raised interest rates. While these rate increases have not had a significant adverse impact on the Company to date, the impact of such rate increases on the overall financial markets and the economy may adversely impact the Company in the future. In addition, the global economy has experienced, and is continuing to experience, high levels of inflation and global supply chain disruptions. The Company continues to monitor these supply chain, inflation and interest rate factors, as well as the uncertainty resulting from the overall economic environment.
Although the Company does not expect to be significantly impacted by the ongoing conflicts in Ukraine or Israel and Gaza, the Company has experienced some constraints in product and material availability and increasing costs required to obtain some materials and supplies as a result of these conflicts on the global economy. To date, the Company’s business has not been materially impacted by the conflicts, however, as the conflicts continue or worsen, it may adversely impact the Company’s business, financial condition, results of operations and/or cash flows.
Concentration of Business Risk
Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash and cash equivalents and marketable securities. As of September 30, 2024 and December 31, 2023, the Company’s marketable securities consist of money market mutual funds, U.S. Treasury securities and commercial paper. The Company also maintains balances in certain operating accounts above federally insured limits and, as a result, the Company is exposed to credit risk in the event of default by the financial institutions to the extent account balances exceed the amount insured by the Federal Deposit Insurance Corporation.
The Company sources certain key materials and components utilized in the Company’s products from single or limited suppliers. Historically, the Company has not experienced significant issues sourcing these materials and components. However, if these suppliers were not able to supply the requested amount of materials or components, it could take a considerable length of time to obtain alternative sources, which could affect the Company’s development efforts and commercial operations.
Segment Reporting
The Company’s Chief Operating Decision Maker, its Chief Executive Officer, reviews the Company’s financial information on a consolidated basis for purposes of allocating resources and evaluating its financial performance. Accordingly, the Company has determined that it operates as a single reportable segment.
Reclassifications
Certain prior year amounts have been reclassified for consistency with the current year’s presentation.
Use of Estimates
The preparation of the Condensed Consolidated Financial Statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions about future events that may affect the amounts recorded in its Condensed Consolidated Financial Statements and accompanying notes. Future events and their effects cannot be determined with certainty. On an ongoing basis, management evaluates these estimates and assumptions. Significant estimates and assumptions include:
valuation allowances with respect to deferred tax assets;
inventory valuation;
assumptions used for leases;
9

valuation of warrant liabilities;
assumptions associated with revenue recognition; and
assumptions underlying the fair value used in the calculation of stock-based compensation.
The Company bases these estimates on historical and anticipated results and trends and on various other assumptions the Company believes are reasonable under the circumstances, including assumptions as to future events. Changes in estimates are recorded in the period in which they become known. Actual results could differ from those estimates, and any such differences may be material to the Condensed Consolidated Financial Statements.
Inventory
Inventory is stated at the lower of cost or net realizable value with cost determined using the first-in, first-out method. Materials that may be utilized for either commercial or, alternatively, for research and development purposes, are classified as inventory. Amounts in inventory used for research and development purposes are charged to research and development expense when the product enters the research and development process and can no longer be used for commercial purposes and, therefore, does not have an “alternative future use” as defined in authoritative guidance.
Inventory valuation is established based on a number of factors including, but not limited to, finished goods not meeting product specifications, product excess and obsolescence, or application of the lower of cost or net realizable value concepts. The determination of events requiring the establishment of inventory valuation, together with the calculation of the amount of such adjustments may require judgment. The Company performs an assessment of the recoverability of capitalized inventory during each reporting period and, if needed, records a write-down of inventory to its estimated net realizable value in the period it is identified. For further discussion related to inventory, please refer to Note 5. Inventory.
Warrant Liabilities
The Company’s outstanding warrants include publicly traded warrants (the “Public Warrants”) and warrants sold in a private placement (the “Private Warrants”). The Public Warrants and Private Warrants meet the definition of a derivative, and the Company recorded these warrants as long-term liabilities in the Condensed Consolidated Balance Sheets at fair value upon initial recognition, with subsequent changes in their respective fair values recognized in the Condensed Consolidated Statements of Operations and Comprehensive Loss at each reporting date. For further discussion related to the Public Warrants and Private Warrants, please refer to Note 11. Warrant Liabilities.
Revenue Recognition
The Company’s revenue is derived from sales of products and services. Product revenue is primarily generated from the sales of instruments and consumables used in protein sequencing and analysis. Service revenue is primarily generated from service maintenance contracts including access to analysis software and advanced training for instrument use. The Company recognizes revenue when or as a customer obtains control of the promised goods and services. The amount of revenue recognized reflects the consideration to which the Company expects to be entitled in exchange for these goods and services. This process involves identifying the contract with a customer, determining the performance obligations in the contract, determining the contract price, allocating the contract price to the distinct performance obligations in the contract, and recognizing revenue as the performance obligations have been satisfied. The Company has made the accounting policy election allowed for under ASC 606-10-32-2A to exclude all sales taxes from transaction price. Revenue recognition for contracts with multiple deliverables is based on the separate satisfaction of each distinct performance obligation within the contract. A performance obligation is considered distinct from other obligations in a contract when it provides a benefit to the customer either on its own or together with other resources that are readily available to the customer and is separately identified in the contract. The Company allocates the transaction price to the performance obligations in a contract with a customer based on the relative standalone selling price of each performance obligation. The Company determines standalone selling price based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions, the Company estimates the standalone selling price taking into account available information and specific factors such as competitive positioning, internal costs, profit objectives, and internally approved pricing guidelines related to the performance obligation.
The Company considers the performance obligation for sales of products satisfied upon shipment of the goods to the customer in accordance with the shipping terms (either upon shipment or delivery), which is when control of the product is deemed to be transferred; this includes instruments and consumables. Customers generally do not have a right to return products, except for defective or damaged products during the warranty period or unless prior written consent is provided.
10

In instances where right of payment or transfer of title is contingent upon the customer’s acceptance of the product, revenue is deferred until all acceptance criteria have been met. Revenues for service maintenance contracts, which start after the first year of purchase and are considered as service type warranties that effectively extend the standard first-year service coverage at the customer’s option, are recognized ratably over the contract service period as these services are performed evenly over time. Revenues for advanced training is recognized at a point in time upon satisfaction of the underlying performance obligation. The Company typically provides a standard one-year warranty, which covers defects in materials, workmanship and manufacturing or performance conditions under normal use and service. The first year of the warranty of the products is considered an assurance-type warranty and is recorded as Cost of revenue within the Condensed Consolidated Statements of Operations and Comprehensive Loss. The Company has determined the standard first-year warranty is not a distinct performance obligation.
The Company disaggregates revenue from contracts with customers by type of revenue. The Company believes product revenue and service revenue aggregate the customer types by nature, amount, timing and uncertainty of its revenue streams. Total revenue generated from domestic sales was $0.4 million and $0.2 million for the three months ended September 30, 2024 and 2023, respectively, and $0.8 million and $0.6 million for the nine months ended September 30, 2024 and 2023, respectively. Total revenue generated from international sales was $0.4 million and immaterial for the three months ended September 30, 2024 and 2023, respectively, and $1.1 million and $0.1 million for the nine months ended September 30, 2024 and 2023, respectively.
Deferred Revenue
Deferred revenue is a contract liability that consists of customer payments received in advance of performance or billings in excess of revenue recognized, net of revenue recognized from the balance at the beginning of the period.

Deferred revenue primarily consists of billings and payments received in advance of revenue recognition from service maintenance contracts including software subscription and advanced training and is reduced as the revenue recognition criteria are met. Deferred revenue that will be recognized as revenue within the succeeding 12-month period is recorded as current and is included within Accrued expenses and other current liabilities in the Company’s Condensed Consolidated Balance Sheets. The portion of deferred revenue where revenue is expected to be recognized beyond 12 months from the reporting date is recorded as non-current deferred revenue and is included in Other long-term liabilities in the Company’s Condensed Consolidated Balance Sheets.
As of both September 30, 2024 and December 31, 2023, the Company recorded $0.1 million of deferred revenue within Accrued expenses and other current liabilities in the Company’s Condensed Consolidated Balance Sheets. As of both September 30, 2024 and December 31, 2023, amounts recorded within Other long-term liabilities in the Company’s Condensed Consolidated Balance Sheets were immaterial. The Company expects to recognize approximately 38% of its remaining performance obligations as revenue for the remainder of the year ending December 31, 2024.
Stock-Based Compensation
Stock-based compensation expense for stock option grants with only service conditions is recognized on a straight-line basis over the requisite service period of the individual grants, which is generally the vesting period, based on the estimated grant date fair values. Stock-based compensation expense for stock option grants subject to performance conditions is recognized on an accelerated basis is recognized as though each vesting portion of the award was, in substance, a separate award.
After the completion of the Business Combination, the Company measures compensation expense for stock-based awards to employees, non-employees and directors based upon the awards’ initial grant-date fair values. Stock-based compensation expense for stock options, restricted stock units and performance-based stock awards is recorded over the requisite service period. For awards with only a service condition, the Company expenses stock-based compensation using the straight-line method over the requisite service period for the entire award. For awards with a market condition, the Company expenses the grant date fair value at the target over the vesting period regardless of the value the award recipients ultimately receive. The fair value of restricted stock unit awards without a market condition is estimated using the current market price of the Company’s Class A common stock on the date of grant. The fair value of stock option grants with a market condition is estimated at the date of grant using the Monte Carlo simulation model (“Monte Carlo”). The fair values of stock option grants with a service condition are estimated as of the date of grant by applying the Black-Scholes option valuation model (“Black-Scholes”). The Monte Carlo and Black-Scholes models incorporate assumptions as to stock price volatility, the
11

expected life of the underlying stock options, a risk-free interest rate and dividend yield. The effect of forfeiture in compensation costs is recognized based on actual forfeitures when they occur.
Black-Scholes is affected by the stock price on the date of the grant as well as assumptions regarding a number of highly complex and subjective variables. These variables include the expected term of the option, expected risk-free interest rate, the expected volatility of Class A common stock, and expected dividend yield; each of which is described below. The assumptions for expected term and expected volatility are the two assumptions that significantly affect the grant date fair value.
Expected Term: The expected term using the “simplified” method, which is the simple average of the vesting period and the contractual term.
Risk-free Interest Rate: The risk-free interest rate for periods within the expected term of the awards is based on the U.S. Treasury yield curve in effect at the time of the grant.
Expected Stock Price Volatility: The Company determined expected annual equity volatility based on a weighted average of the historical volatility of its Class A common stock and that of a selected peer group of comparable companies as the Company does not have a sufficient historical trading history of its own Class A common stock.
Dividend Yield: Because the Company has never paid a dividend and does not expect to begin doing so in the foreseeable future, the Company assumes no dividend yield in valuing the stock-based awards.
Exercise Price: The exercise price is taken directly from the grant notice issued to employees and nonemployees.

Note 4. Fair Value of Financial Instruments
Fair value estimates of financial instruments are made at a specific point in time, based on relevant information about financial markets and specific financial instruments. As these estimates are subjective in nature, involving uncertainties and matters of significant judgment, they cannot be determined with precision. Changes in assumptions can significantly affect estimated fair value.
The Company measures fair value 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 reporting date. The Company utilizes a three-tier hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value:
Level 1: Valuations based on quoted prices in active markets for identical assets or liabilities that an entity has the ability to access.
Level 2: Valuations based on quoted prices for similar assets or liabilities, quoted prices for identical assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities.
Level 3: Valuations based on inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
The carrying value of cash and cash equivalents, accounts payable and accrued expenses and other current liabilities approximates their fair values due to the short-term or on demand nature of these instruments. At September 30, 2024 and December 31, 2023, the Company’s investment portfolio included available-for-sale securities which were comprised of money market funds, U.S. treasury bills and commercial paper. The Company has U.S. Treasury bills and commercial papers that are classified as Level 2 due to the fair value for these instruments being determined by utilizing observable inputs in similar assets or identical assets in non-active markets. The fair value of certain of the U.S. Treasury bills transferred to Level 2 from Level 1 of the fair value hierarchy due to trading activity, observability and accessibility of the pricing information from the most active market of the investment.
Warrants are recorded as Warrant liabilities in the Condensed Consolidated Balance Sheets. The warrant liabilities are measured at fair value at inception and on a recurring basis, with changes in fair value presented as Change in fair value of warrant liabilities in the Condensed Consolidated Statements of Operations and Comprehensive Loss.
14

The Public Warrants and Private Warrants were carried at fair value as of September 30, 2024 and December 31, 2023. The Public Warrants were valued using Level 1 inputs as they are traded in an active market. The Private Warrants were valued using a binomial lattice model. The primary unobservable input utilized in determining the fair value of the Private Warrants was the expected volatility of the Company’s Class A common stock. The expected volatility was based on consideration of the implied volatility from the Company’s own Public Warrant pricing and on the historical volatility observed at guideline public companies. As of September 30, 2024, the significant assumptions used in preparing the binomial lattice model for valuing the Private Warrants liability include (i) volatility of 121.2%, (ii) risk-free interest rate of 3.7%, (iii) strike price of $11.50, (iv) fair value of Class A common stock of $0.88, and (v) expected life of 1.7 years. As of December 31, 2023, the significant assumptions used in preparing the binomial lattice model for valuing the Private Warrants liability include (i) volatility of 92.1%, (ii) risk-free interest rate of 4.10%, (iii) strike price of $11.50, (iv) fair value of Class A common stock of $2.01, and (v) expected life of 2.4 years.
There were no exercises or redemptions of the Public Warrants or Private Warrants during the three and nine months ended September 30, 2024 and 2023.
The following table summarizes the Company’s assets and liabilities in the Condensed Consolidated Balance Sheets as of September 30, 2024 and December 31, 2023, that are measured at fair value on a recurring basis, by level, within the fair value hierarchy (in thousands):

In December 2021, the Company signed a 10-year lease for approximately 67,000 square feet of space in New Haven, Connecticut. The lease commenced on January 8, 2022 with rent payments beginning on July 7, 2022. Under the lease, the landlord contractually agreed to reimburse the Company for up to $9.1 million in improvements to the space, to be used for such improvements as the Company deems “necessary or desirable”. On September 13, 2022, the Company filed a lawsuit against the landlord, alleging that the landlord has: (i) refused to reimburse the Company for costs related to improvements already incurred and submitted, (ii) delayed the Company’s completion of improvements, in order to avoid reimbursing the costs of those improvements, and (iii) improperly rejected the Company’s proposed improvement plans. The Company accounted for these lease incentives as an offset to the lease liability recorded at the inception of the lease. In September 2024, the Company determined there was a change in the estimated timing of receipt of reimbursements for the improvements. This resulted in an increase of the carrying value of the right-of-use asset and the corresponding lease liabilities of $1.0 million. Although the Company believes it is contractually entitled to the $9.1 million of lease incentives, based on the current status of the litigation, the Company cannot determine the likely outcome or estimate the impact on such carrying values.
As of September 30, 2024 and December 31, 2023, the Company incurred and recognized total leasehold improvements of approximately $1.2 million and $1.6 million, respectively, related to reimbursable construction costs which are included in construction in progress within Property and equipment, net, on the Condensed Consolidated Balance Sheets.

Note 9. Stock-based Compensation
Equity Incentive Plan
The Quantum-Si Incorporated 2021 Equity Incentive Plan (the “2021 Plan”) provides for grants of stock options, stock appreciation rights, restricted stock, restricted stock units, and other stock or cash-based awards. Directors, officers and other employees of the Company and its subsidiaries, as well as others performing consulting or advisory services for the Company, are eligible for grants under the 2021 Plan. As of September 30, 2024, there were 13,204,915 shares available for future grant under the 2021 Plan.
Inducement Equity Incentive Plan
On May 8, 2023, the Company adopted the 2023 Inducement Equity Incentive Plan (the “2023 Inducement Plan”) to reserve 3,000,000 shares of its Class A common stock to be used exclusively for grants of awards to individuals that were not previously employees or directors of the Company as a material inducement to such individuals’ entry into employment with the Company within the meaning of Rule 5635(c)(4) of the Nasdaq Listing Rules. On August 23, 2024, the Company amended the 2023 Inducement Plan to reserve an additional 3,000,000 shares of its Class A common stock under the 2023 Inducement Plan. As of September 30, 2024, there were 2,268,867 shares available for future issuance under the 2023 Inducement Plan, as amended. The terms and conditions of the 2023 Inducement Plan, as amended, are substantially similar to those of the 2021 Plan.
Stock Options
The Company recorded $1.7 million and $1.1 million for stock-based compensation related to stock options for the three months ended September 30, 2024 and 2023, respectively, and $4.8 million and $5.7 million for stock-based compensation related to stock options for the nine months ended September 30, 2024 and 2023, respectively.
18

The Company estimates and records the compensation cost associated with the grants described above with an offsetting entry to paid-in capital. The Company utilized the Black-Scholes option pricing model for determining the estimated fair value for service or performance-based stock awards where performance is not tied to market conditions. The Black-Scholes option pricing model requires the use of subjective assumptions which determine the fair value of stock-based awards.
The fair value of each stock option award granted during the nine months ended September 30, 2024 was estimated as of the grant date using a Black-Scholes model with the following assumptions:
Nine months ended

Modification of Performance Stock Options
In November 2022 and May 2023, the Company granted 2,780,000 and 1,000,000 performance-based stock option awards to its Chief Executive Officer and Chief Financial Officer, respectively. The vesting of these awards are subject to continued service to the Company and certain market conditions. The market conditions require the Company’s Class A common stock trade above specified levels for certain periods of time. The fair values of the awards were estimated at the grant date using the Monte Carlo simulation model.
On March 15, 2024, the market conditions that trigger the vesting of these performance-based stock option awards were modified. The modified market conditions require the Company’s Class A common stock to trade above specified levels for certain defined periods of time that are different from the original awards. The Company accounted for the modifications as modifications of market conditions. The total incremental stock-based compensation expense to be recognized for these awards is approximately $2.4 million within Selling, general and administrative operating expenses in the Condensed Consolidated Statements of Operations and Comprehensive Loss. Incremental stock-based compensation expense for the three and nine months ended September 30, 2024 was $0.2 million and $0.4 million, respectively. There were no such modifications to performance-based stock option awards for the three and nine months ended September 30, 2023.

Restricted Stock Units
The Company recorded $0.7 million of stock-based compensation expense related to restricted stock unit (“RSU”) awards for the three months ended September 30, 2024. Stock-based compensation expense related to RSU awards for the three months ended September 30, 2023 was immaterial. The Company recorded $1.7 million and $1.2 million of stock-based compensation expense related to RSU awards for the nine months ended September 30, 2024 and 2023, respectively. The nine months ended September 30, 2023 included a reversal of stock-based compensation expense for the Company’s former Chief Financial Officer and certain members of the Company’s board of directors (the “Board”) as the service conditions of certain awards previously granted were not met.

Note 10. Net Loss Per Share
The Company presents both basic earnings per share (“EPS”) and diluted EPS. Basic net loss per share is computed by dividing net loss by the weighted-average number of shares of common stock outstanding for the period. Diluted net loss per share is computed by giving effect to all common share equivalents to the extent they are dilutive. Basic and diluted net loss per share was the same for each period presented as the inclusion of all common share equivalents would have been anti-dilutive.
The following table presents the calculations for the three and nine months ended September 30, 2024 and 2023 of basic and diluted net loss per share for the Company’s common stock (in thousands, except per share amounts):

Note 11. Warrant Liabilities
Public Warrants
As of September 30, 2024 and December 31, 2023, there were an aggregate of 3,833,319 outstanding Public Warrants, which entitle the holder to acquire Class A common stock. Each whole warrant entitles the registered holder to purchase one share of Class A common stock at an exercise price of $11.50 per share, subject to adjustment as discussed below, beginning on September 9, 2021. The warrants will expire on June 10, 2026 or earlier upon redemption or liquidation.
Redemptions
At any time while the warrants are exercisable, the Company may redeem not less than all of the outstanding Public Warrants:
in whole and not in part;
at a price of $0.01 per warrant;
upon not less than 30 days’ prior written notice of redemption (the “30-day redemption period”) to each warrant holder; and
if, and only if, the closing price of the Company’s Class A common stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading day period ending three business days before the Company sends the notice of redemption to the warrant holders.
If the foregoing conditions are satisfied and the Company issues a notice of redemption of the Public Warrants at $0.01 per warrant, each holder of Public Warrants will be entitled to exercise their Public Warrants held prior to the scheduled redemption date.

If the Company calls the Public Warrants for redemption for $0.01 as described above, the Board may elect to require any holder that wishes to exercise his, her or its Public Warrants to do so on a “cashless basis.” If the Board makes such election, all holders of Public Warrants would pay the exercise price by surrendering their warrants for that number of shares of Class A common stock equal to the quotient obtained by dividing (x) the product of the number of shares of Class A common stock underlying the warrants, multiplied by the excess of the “fair market value” over the exercise price of the warrants by (y) the “fair market value”. For purposes of the redemption provisions of the warrants, the “fair market value” means the average last reported sale price of the Class A common stock for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants.
The Public Warrants do not meet the criteria to be classified in stockholders’ equity as the exercise of the Public Warrants may be settled in cash upon the occurrence of a tender offer or exchange offer in which the maker of the tender offer or exchange offer, upon completion of the tender offer or exchange offer, beneficially owns more than 50% of the outstanding shares of the Company’s Class A common stock, even if it would not result in a change of control of the Company. This provision precludes the Public Warrants from being classified in equity and thus they are classified as long-term liabilities in the Condensed Consolidated Balance Sheets.
Private Warrants
As of September 30, 2024 and December 31, 2023, there were 135,000 Private Warrants outstanding. The Private Warrants are identical to the Public Warrants, except that so long as they are held by HighCape Capital Acquisition LLC or any of its permitted transferees, (i) the Private Warrants and the shares of Class A common stock issuable upon the exercise of the Private Warrants were not transferable, assignable or saleable until 30 days after the completion of the Business Combination, (ii) the Private Warrants will be exercisable for cash or on a cashless basis, at the holder’s option, and (iii) the Private Warrants are not subject to the Company’s redemption option at the price of $0.01 per warrant. The Private Warrants are subject to the Company’s redemption option at the price of $0.01 per warrant, provided that the other conditions of such redemption are met, as described above. If the Private Warrants are held by a holder other than HighCape Capital Acquisition LLC or any of its permitted transferees, the Private Warrants will be redeemable by the Company in all redemption scenarios applicable to the Public Warrants and exercisable by such holders on the same basis as the Public Warrants.
The Private Warrants do not meet the criteria to be classified in stockholders’ equity as the terms of the warrants provide for potential changes to the settlement amounts depending upon the characteristics of the warrant holder, and, because the holder of a warrant is not an input into the pricing of a fixed-for-fixed option on equity shares. This provision precludes the Private Warrants from being classified in equity and thus they are classified as long-term liabilities in the Condensed Consolidated Balance Sheets.
The fair value of warrant liabilities was $0.4 million and $1.3 million as of September 30, 2024 and December 31, 2023, respectively. The Company recognized a gain of $0.1 million and a loss of $0.2 million as a Change in fair value of warrant liabilities in the Condensed Consolidated Statements of Operations and Comprehensive Loss for the three months ended September 30, 2024 and 2023, respectively. The Company recognized a gain of $0.9 million and a loss of $0.1 million as a Change in fair value of warrant liabilities in the Condensed Consolidated Statements of Operations and Comprehensive Loss for the nine months ended September 30, 2024 and 2023, respectively. There were no exercises or redemptions of the Public Warrants or Private Warrants during the three and nine months ended September 30, 2024 or 2023.
Note 12. Restructuring
The Company committed to organizational restructurings during the first and third quarters of 2023, designed to decrease its costs and create a more streamlined organization to support its business. As of December 31, 2023, the Company recorded a restructuring liability of $0.5 million which is included in Accrued expenses and other current liabilities in the Condensed Consolidated Balance Sheets. As of September 30, 2024, the Company had no remaining restructuring liability.
The Company’s restructuring costs, primarily for cash severance and other severance costs, are allocated to the following operating expense categories as follows (in thousands):

The Company’s restructuring activities were complete as of March 31, 2024. The Company does not expect to incur additional charges associated with these activities.
Note 13. Income Taxes
Income taxes for the three and nine months ended September 30, 2024 and 2023 were recorded at the Company’s estimated annual effective income tax rate, subject to adjustments for discrete events, if they occur. The Company’s estimated annual effective tax rate for the three and nine months ended September 30, 2024 was (0.17)% and (0.06)%, respectively. The Company’s estimated annual effective tax rate for each of the three and nine months ended September 30, 2023 was 0.0%. The primary reconciling items between the federal statutory rate of 21.0% and the Company’s overall effective tax rate for these periods were related to stock-based compensation, the valuation allowance recorded against the full amount of the Company’s net deferred tax assets and foreign taxes.
A valuation allowance is required when it is more likely than not that some portion or all of the Company’s deferred tax assets will not be realized. The realization of deferred tax assets depends on the generation of sufficient future taxable income during the period in which the Company’s related temporary differences become deductible. Management believes that based on the earnings history of the Company, it is more likely than not that the benefits of these assets will not be realized, and therefore, a full valuation allowance has been recorded against the Company’s net deferred tax assets as of September 30, 2024 and December 31, 2023.
Note 14. Related Party Transactions
Effective as of February 17, 2021, legacy Quantum-Si entered into a Master Services Agreement (“MSA”) with 4Catalyzer Corporation (“4C”), a company controlled by Dr. Jonathan Rothberg, a member of the Board, pursuant to which the Company may engage 4C to provide services such as general administration, facilities, information technology, financing, legal, human resources and other services, through future statements of work and under terms and conditions to be determined by the parties with respect to any services to be provided.

Note 15. Commitments and Contingencies
Commitments
Licenses related to certain intellectual property:
The Company licenses certain intellectual property, some of which may be utilized in its current or future product offerings. To preserve the right to use such intellectual property, the Company is required to make annual minimum fixed payments totaling approximately $0.1 million as well as royalties based on net sales if the royalties exceed annual minimum fixed payments. As of September 30, 2024 and December 31, 2023, the Company had accrued royalties of approximately $0.1 million included in Accrued expenses and other current liabilities in the Condensed Consolidated Balance Sheets.
Other commitments:
The Company sponsors a 401(k) defined contribution plan covering all eligible U.S. employees (the “401(k) Plan”). Contributions to the 401(k) Plan are discretionary. The Company did not make any matching contributions to the 401(k) Plan for the three and nine months ended September 30, 2024 and 2023.
Contingencies
The Company is subject to claims in the ordinary course of business. The Company accrues contingent liabilities to the extent the liability is probable and estimable.

On May 16, 2024, a punitive class action lawsuit was filed in the Delaware Court of Chancery, styled Farzad v. HighCape Capital, et al. (the “Delaware Stockholder Litigation”). The Delaware Stockholder Litigation asserts breach of fiduciary duty claims against the former officers and directors of HighCape, including Kevin Rakin, Matt Zuga, David Colpman, Robert Taub and Antony Loebel, HighCape Capital Acquisition LLC and HighCape Capital L.P., aiding and abetting breach of fiduciary duty claims against Foresite Capital Management, LLC and Dr. Rothberg, and unjust enrichment claims against all defendants related to the Business Combination. The Delaware Stockholder Litigation complaint alleges that the transactions contemplated by the Business Combination were a product of an unfair process which was allegedly impacted by conflicts of interest, resulting in mispricing of the Business Combination. The complaint seeks, among other things, unspecified damages and attorneys’ fees and costs. On July 29, 2024, the defendants filed motions to dismiss the Delaware Stockholder Litigation complaint. There is no assurance that defendants will be successful in the defense of the litigation or that insurance will be available or adequate to fund any potential settlement or judgment or the litigation costs of the action. At the time of this filing the outcome of this matter is not estimable or probable.
In April 2023, the Company informed the contract manufacturer that had manufactured its Platinum® and Carbon™ instruments that it intended to wind down the relationship and transition to a different contract manufacturer. In October 2023, the former contract manufacturer filed a complaint against the Company in the State of Texas alleging breach of contract and made claims for economic damage and attorney costs. In January 2024, the suit was withdrawn and refiled in the State of Minnesota alleging similar claims. Although it is not possible to determine the potential financial exposure associated with the alleged claim at this time given its early stage, the Company believes it has a meritorious defense and intends to vigorously defend against all claims asserted in the complaint. At the time of this filing the outcome of this matter is not estimable or probable.
24

The Company enters into agreements that contain indemnification provisions with other parties in the ordinary course of business, including business partners, investors, contractors, and the Company’s officers, directors and certain employees. The Company has agreed to indemnify and defend the indemnified party claims and related losses suffered or incurred by the indemnified party from actual or threatened third-party claims because of the Company’s activities or non-compliance with certain representations and warranties made by the Company. It is not possible to determine the maximum potential loss under these indemnification provisions due to the Company’s limited history of prior indemnification claims and the unique facts and circumstances involved in any particular case. To date, losses recorded in the Condensed Consolidated Statements of Operations and Comprehensive Loss in connection with the indemnification provisions have not been material.
Note 16. Subsequent Event
Nasdaq Deficiency Notice

Overview
We are an innovative life sciences company with the mission of transforming single-molecule analysis and democratizing its use by providing researchers and clinicians access to the proteome, the set of proteins expressed within a cell. We have developed a proprietary universal single-molecule detection platform that we are first applying to proteomics to enable Next-Generation Protein Sequencing (“NGPS”), the ability to sequence proteins in a massively parallel fashion (rather than sequentially, one at a time), that can be used for the study of nucleic acids. Our platform was designed to offer an end-to-end workflow including both sample preparation and sequencing and is comprised of our Platinum® NGPS instrument, the Platinum Analysis Software service, and reagent kits and proprietary semiconductor chips for use with our Platinum® instrument. We began a controlled launch of the Platinum® instrument in December 2022 and subsequently initiated a full commercial launch at the end of the first quarter of 2024.
Now that our Platinum® and Platinum Analysis Software system has launched, we intend to follow a systematic, phased approach to continue to successfully launch updates to our platform. We believe we are the first company to successfully enable NGPS on a semiconductor chip, thus digitizing a massive proteomics opportunity, which allows for a massively parallel solution at the ultimate level of sensitivity - single-molecule detection. We believe our platform, which is designed to streamline sequencing and data analysis at a lower instrument cost than legacy proteomic solutions, could allow our product to have wide utility across the study of the proteome. For example, we believe our platform could be used for biomarker discovery and disease detection, pathway analysis, immune response, vaccine development, quality assurance and quality control, among other applications.
