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 impact of general conditions in the global economy and in the global financial markets, including changes in inflation, interest rates, tariffs, retaliatory trade policies including limitations of shipments of products, and overall economic conditions and uncertainties;

•maintaining 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 our Platinum® line of instruments, our consumable kits 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

•our financial performance.

These forward-looking statements are based on information available as of the date of this report and current expectations, forecasts and assumptions, and involve a number of judgments, risks and uncertainties. Important factors could cause actual results, performance or achievements to differ materially from those indicated or implied by forward-looking statements such as those described in Part I, Item 1A, “Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, this Quarterly Report on Form 10-Q, and in other filings that we make with the Securities and Exchange Commission. The risks described under the heading “Risk Factors” are not exhaustive. New risk factors emerge from time to time, and it is not possible to predict all such risk factors, nor can we assess the impact of all such risk factors on our business or the extent to which any factor or combination of factors may cause actual results to differ materially from those contained in any forward-looking statements. Forward-looking statements are not guarantees of performance. You should not put undue reliance on these statements, which speak only as of the date hereof. All forward-looking statements attributable to us or persons acting on our behalf are expressly qualified in their entirety by the

foregoing cautionary statements. We undertake no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

QUANTUM-SI INCORPORATED

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1. Description of Business and Basis of Presentation

Background

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.

Quantum-Si is a life sciences company focused on proteomics research, 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 it is applying to proteomics to enable Next-Gen Protein SequencingTM (“NGPS”), to sequence proteins in a massively parallel fashion (rather than sequentially, one at a time), which can also be used for the study of nucleic acids. The Company believes that the ability to sequence proteins in a massively parallel fashion and offer a fast analysis time provides NGPS with the potential to unlock significant biological information through improved resolution and unbiased access to the proteome at a speed and scale that is not available today. Traditionally, proteomic workflows to sequence proteins required days or weeks to complete. The Company’s platform includes its Platinum line of NGPS instruments, Platinum Analysis Software, and consumable kits for use with its Platinum line of 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. The Company has incurred significant losses and negative cash flows from operations in all periods since inception and had an accumulated deficit of $615.8 million as of March 31, 2025. The Company has incurred significant operating losses, including net losses of $19.2 million and $19.5 million for the three months ended March 31, 2025 and 2024, respectively. As of March 31, 2025, the Company had cash, cash equivalents and investments in marketable securities of $232.6 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.

Global Developments

Although the U.S. Federal Reserve lowered interest rates slightly in 2024, it is not known whether additional action will be taken to lower interest rates and if this decrease, and any other decreases, will have an impact on inflation. While these rate fluctuations 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.

To date, the Company has not been materially affected by enacted tariffs either by the U.S. government or foreign retaliatory tariffs, however, the Company’s finished goods and/or their components could become materially affected by changing tariffs in the future. If increased tariffs are imposed on the Company’s finished goods and/or components, they may impact the business, financial condition, results of operations and cash flows.

Table of Contents

Although the Company has not been significantly impacted by geopolitical conflicts such as those 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 business has not been materially impacted by these conflicts, however, as the conflicts continue or worsen, it may impact the business, financial condition, results of operations and cash flows.

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, 2024. The Condensed Consolidated Balance Sheet as of December 31, 2024 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 periods. The results for the three months ended March 31, 2025 are not necessarily indicative of the results to be expected for any subsequent quarter, the year ending December 31, 2025, 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, 2024.

Reclassifications

Certain prior year amounts have been reclassified for consistency with the current year’s presentation.

Note 2. Summary of Significant Accounting Policies

For the Company’s Significant Accounting Policies, please refer to its Annual Report on Form 10-K for the fiscal year ended December 31, 2024. Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the Accounting Standards Codification and Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”).

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 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:

•inventory valuation;

•assumptions used for leases;

•valuation of warrant liabilities;

•valuation allowances with respect to deferred tax assets;

•assumptions associated with revenue recognition; and

•assumptions underlying the fair value used in the calculation of the 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

Table of Contents

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.

Recently Issued Accounting Pronouncements

In November 2024, the FASB issued ASU No. 2024-03, Disaggregation of Income Statement Expenses (“DISE”), which requires additional disclosure of the nature of expenses included in the income statement. The ASU requires disclosures about specific types of expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses. The amendments in this update are effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027, with early adoption permitted. The ASU is required to be applied prospectively with the option for retrospective application. The Company is currently evaluating the impact ASU 2024-03 may have on its Consolidated Financial Statements and disclosures.

In March 2024, the FASB issued ASU No. 2024-02, Codification Improvements - Amendments to Remove References to the Concepts Statements, which contains amendments to the Codification that remove references to various Concepts Statements. The amendments in ASU 2024-02 are not intended to result in significant accounting changes for most entities. The Company adopted ASU 2024-02 effective January 1, 2025. The adoption of ASU 2024-02 did not have a material impact to the Consolidated Financial Statements and disclosures.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which expands income tax disclosure requirements to include additional information related to the rate reconciliation of effective tax rates to statutory rates, as well as additional disaggregation of taxes paid in both U.S. and foreign jurisdictions. The amendments in ASU 2023-09 also remove disclosures related to certain unrecognized tax benefits and deferred taxes. The amendments are effective for fiscal years beginning after December 31, 2024, with early adoption permitted. The new standard is expected to apply prospectively, but retrospective application is permitted. The Company will adopt the new standard for the year ended December 31, 2025 and is currently evaluating the impact ASU 2023-09 may have on its Consolidated Financial Statements and disclosures.

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.

Table of Contents

•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. As of March 31, 2025 and December 31, 2024, 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.

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.

The Public Warrants and Private Warrants were carried at fair value as of March 31, 2025 and December 31, 2024. 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 March 31, 2025, the assumptions used in preparing the binomial lattice model for valuing the Private Warrants liability include (i) volatility of 201.5%, (ii) risk-free interest rate of 4.0%, (iii) strike price of $11.50, (iv) fair value of Class A common stock of $1.20, and (v) expected life of 1.2 years. As of December 31, 2024, the assumptions used in preparing the binomial lattice model for valuing the Private Warrants liability include (i) volatility of 194.3%, (ii) risk-free interest rate of 4.2%, (iii) strike price of $11.50, (iv) fair value of Class A common stock of $2.70, and (v) expected life of 1.4 years.

There were no exercises or redemptions of the Public Warrants or Private Warrants during the three months ended March 31, 2025 and 2024.

The following table summarizes the Company’s assets and liabilities in the Condensed Consolidated Balance Sheets as of March 31, 2025 and December 31, 2024, that are measured at fair value on a recurring basis, by level, within the fair value hierarchy (in thousands):

Stock Options

The Company granted an aggregate of 32,000 stock option awards to participants during the three months ended March 31, 2025, with vesting subject to the participant’s continued employment with or continued service provided to the Company through the applicable vesting dates. During the three months ended March 31, 2024, the Company did not grant any stock options to participants.

The Company recorded $1.5 million and $1.3 million for stock-based compensation related to stock options for the three months ended March 31, 2025 and 2024, respectively.

The fair value of each stock option award granted during the three months ended March 31, 2025 was estimated as of the grant date using a Black-Scholes model with the following assumptions:


						Three months ended March 31, 2025
Expected term (in years)						4.6
Risk-free interest rate						4.4%
Expected volatility						114.2%
Expected dividend yield						—
Weighted average grant date fair value per share						$1.88

A summary of the stock option activity for the three months ended March 31, 2025 is presented in the table below:


	Number of Options	Weighted Average Exercise Price (per share)		Weighted Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (in thousands)
Outstanding at December 31, 2024	20,803,142	$	2.61	7.8	$	11,507
Granted	32,000	2.35
Exercised	(623,834)	2.57
Forfeited	(599,063)	4.76

Vested and expected to vest at March 31, 2025	16,987,541	$	2.62	7.6	$	134

As of March 31, 2025, total unrecognized stock-based compensation related to stock options was $9.9 million, which is expected to be recognized over a remaining weighted average vesting period of 2.2 years.

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 within Selling, general and administrative operating expenses in the Condensed Consolidated Statements of Operations and Comprehensive Loss is approximately $2.4 million. Incremental stock-based compensation

Table of Contents

expense for the three months ended March 31, 2025 was $0.2 million. Incremental stock-based compensation expense for the three months ended March 31, 2024 was immaterial.

Restricted Stock Units

The Company recorded $0.8 million and $0.3 million of stock-based compensation expense related to restricted stock unit (“RSU”) awards for the three months ended March 31, 2025 and 2024, respectively.

Vested	(358,511)	1.86
Forfeited	(72,292)	1.52
Outstanding non-vested RSUs at March 31, 2025	14,852,679	$	1.28

As of March 31, 2025, total unrecognized stock-based compensation related to restricted stock was $18.2 million, which is expected to be recognized over the remaining weighted average vesting period of 3.6 years.

Stock-based compensation is allocated to Research and development and Selling, general and administrative operating expenses in the Condensed Consolidated Statements of Operations and Comprehensive Loss. Stock-based compensation expense for the years ended March 31, 2025 and 2024 is as follows (in thousands):

No related tax benefits of the stock-based compensation expense have been recognized and no related tax benefits have been realized from the exercise of stock options due to the Company’s net operating loss carryforwards.

Note 11. Warrant Liabilities

Public Warrants

As of March 31, 2025 and December 31, 2024, 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

Table of Contents

•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 March 31, 2025 and December 31, 2024, 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.

As of March 31, 2025 and December 31, 2024, the combined fair value of warrant liabilities was $1.6 million and $5.0 million, respectively. The Company recognized gains of $3.4 million and $0.3 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 March 31, 2025 and 2024, respectively. There were no exercises or redemptions of the Public Warrants or Private Warrants during the three months ended March 31, 2025 or 2024.

For further details regarding the warrant liabilities, please refer to Note 4 . Fair Value of Financial Instruments.

Note 12. Net Loss Per Share

The Company presents both basic earnings per share (“EPS”) and diluted EPS. 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.

Table of Contents

The following table presents the calculations for the three months ended March 31, 2025 and 2024 of basic and diluted net loss per share for the Company’s common stock (in thousands, except per share amounts):

Basic and diluted net loss per share	$	(0.11)	$	(0.14)

Net loss per share attributable to Class A and Class B common stockholders was the same on a basic and diluted basis, as the inclusion of all potential common equivalent shares outstanding would have been anti-dilutive. The following potential dilutive shares were excluded from the calculation of diluted net loss per share because their effect would be anti-dilutive for the three months ended March 31, 2025 and 2024 (in thousands):


	Three months ended March 31,
	2025	2024
Outstanding options to purchase common stock	19,612,245	22,101,807

Note 13. Restructuring

The Company committed to organizational restructurings during the fourth quarter of 2024, designed to decrease its costs and create a more streamlined organization to support its business. Restructuring liabilities were $0.3 million and $0.7 million as of March 31, 2025 and December 31, 2024, respectively. These liabilities are included in Accrued expenses and other current liabilities in the Condensed Consolidated Balance Sheets.

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):


	Research and development		Selling, general and administrative		Total
Balance as of December 31, 2024	$	513	$	166	$	679

Cash payments and other adjustments(1)	(212)		(142)		(354)

Total liabilities as of March 31, 2025					$	325

(1) Cash payments and other adjustments include charges related to health care coverage for a specified period of time after separation.

The Company’s restructuring activities were complete as of December 31, 2024. The Company does not expect to incur additional charges associated with these activities.

Note 14. Income Taxes

Income taxes for the three months ended March 31, 2025 and 2024 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 was (0.06)% and 0.00% for the three months ended March 31, 2025 and 2024, respectively. The primary reconciling items between the federal statutory rate of 21.0% and the Company’s overall effective tax rates for these periods were related to the effects of deferred state income taxes, stock-based compensation, changes in the fair value of warrant liabilities, research and development credits and the valuation allowance recorded against the full amount of the Company’s net deferred tax assets. In addition to the previously mentioned reconciling items, the reconciling items for the three months ended March 31, 2025 also included 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 March 31, 2025 and December 31, 2024.

Note 15. Segment Information

The Company’s Chief Operating Decision Maker (the “CODM”), its Chief Executive Officer, reviews financial information presented on a consolidated basis for purposes of assessing financial performance, making operating decisions and allocating resources. Accordingly, the Company has determined that it operates as a single reportable segment. The CODM utilizes the Company’s long-range plan, which includes product development roadmaps and long-range financial models, as a key input to resource allocation. The CODM makes decisions on resource allocation, assesses the performance of the business, and monitors budget versus actual results on a consolidated basis using loss from operations as reported on the Condensed Consolidated Statements of Operations and Comprehensive Loss. Net loss and the change in cash and cash equivalents and marketable securities are also measures that are considered in monitoring budget versus actual results.

Significant expenses within loss from operations, as well as within net loss, include research and development, and selling, general and administrative expenses, which are each separately presented on the Company’s Condensed Consolidated Statements of Operations and Comprehensive Loss.

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.

Note 16. Related Party Transactions

The Company was a party to the Amended and Restated Technology Services Agreement (the “ARTSA”), most recently amended on November 11, 2020, by and among 4Catalyzer Corporation (“4C”), the Company and other participant companies controlled by Dr. Jonathan Rothberg, the Chairman of the Company’s Board of Directors. The Company entered into a First Addendum to the ARTSA on February 17, 2021 pursuant to which the Company agreed to terminate its participation under the ARTSA no later than immediately prior to the effective time of the Business Combination, resulting

Table of Contents

in the termination of the Company’s participation under the ARTSA on June 10, 2021. In connection with the termination of the Company’s participation under the ARTSA, the Company terminated its existing arm’s length lease agreement with 4C and negotiated an arm’s length lease agreement. Under the ARTSA, the Company and the other participant companies had agreed to share certain non-core technologies, which means any technologies, information or equipment owned or otherwise controlled by the participant company that are not specifically related to the core business area of the participant and subject to certain restrictions on use. The ARTSA also provided for 4C to perform certain services for the Company and each other participant company such as monthly administrative, management and technical consulting services to the Company which were pre-funded approximately once per quarter.

The Company incurred expenses paid to 4C of $0.1 million for both the three months ended March 31, 2025 and 2024. These expenses included amounts for month-to-month sublease arrangements for office and laboratory spaces from 4C and certain administrative expenses. These amounts are included in Selling, general and administrative expenses in the Condensed Consolidated Statements of Operations and Comprehensive Loss. As of both March 31, 2025 and December 31, 2024 amounts due to 4C were immaterial.

The ARTSA also provided for the participant companies to provide other services to each other. As of both March 31, 2025 and December 31, 2024, there were no amounts payable to or from the Company related to these services.

Effective November 1, 2022, the Company entered into an Advisory Agreement with Dr. Rothberg (the “Advisory Agreement”), pursuant to which Dr. Rothberg previously served as Chairman of the Board, advises the Chief Executive Officer and the Board on strategic matters, and provides consulting, business development and similar services on matters relating to the Company’s current, future and potential scientific and strategic initiatives and such other consulting services reasonably requested from time to time. Pursuant to the Advisory Agreement, as compensation for the services provided, in March 2023, the Company granted Dr. Rothberg an option to purchase 250,000 shares of Class A common stock pursuant to the 2021 Plan. In connection with the Advisory Agreement, Dr. Rothberg’s title was changed from Executive Chairman to Chairman of the Board. Subsequently, in May 2024, with Charles Kummeth’s appointment as Chairman of the Board, Dr. Rothberg’s title was changed from Chairman of the Board to Director.

Contingencies

The Company is subject to claims in the ordinary course of business. Except as discussed below, the Company is not currently a party to any pending or threatened litigation, the outcome of which would be expected to have a material adverse effect on its financial condition, results of operations, or cash flows. The Company discloses contingent liabilities even if the liability is not probable or estimable, or both, if there is a reasonable possibility that a material loss may have been incurred.

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,

Table of Contents

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. As of May 15, 2025, the parties were working through various motions associated with the case and no trial date has been set. Quantum-Si, as part of the Business Combination, had previously agreed to indemnify certain of the defendants related to actions such as the Delaware Stockholder Litigation to the extent allowable by law. 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. Further, since the Quantum-Si has indemnified certain of the defendants to the extent allowable by law, there is no guarantee that insurance available to Quantum-Si will be available or adequate to fund any potential settlement or judgment or related costs associated with the indemnified parties. 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 the Platinum and another development product, Carbon™, 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. The Company denied all liability and countersued alleging claims of negligence. In February 2025, the court ordered mandatory non-binding settlement conference to take place on June 27, 2025. 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.

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.

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.

Overview

We are a life sciences company focused on proteomics research, 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 applying to proteomics to enable Next-Gen Protein SequencingTM (“NGPS”), to sequence proteins in a massively parallel fashion (rather than sequentially, one at a time), which can also be used for the study of nucleic acids. We believe that the ability to sequence proteins in a massively parallel fashion and offer a fast analysis time provides NGPS with the potential to unlock significant biological information through improved resolution and unbiased access to the proteome at a speed and scale that is not available today. Traditionally, proteomic workflows to sequence proteins required days or weeks to complete. Our platform includes our Platinum NGPS instrument, Platinum Analysis Software, and consumable kits for use with our Platinum line of instruments. In 2021, we introduced our Platinum early access program to sites with participation from leading academic centers and key industry partners. The early access program introduced the Platinum single-molecule sequencing system to key opinion leaders across the globe for both expansion and development of applications and workflows. We began a controlled launch of the Platinum instrument and started to take orders in December 2022, and subsequently began a controlled commercial launch of Platinum in January 2023, and then moved to a full commercial launch of Platinum beginning the second quarter of 2024. In January 2025, we announced the launch of our Platinum Pro benchtop sequencer. First shipments of Platinum Pro occurred in March 2025.

Going forward, we intend to follow a systematic, phased approach to continue to successfully launch updates and enhancements to our platform which can include improvements to our hardware, software and chemistry that works together to produce the overall platform.

We believe that our platform offers a differentiated solution in a rapidly evolving proteomics tools market. Within our initial focus market of proteomics, our platform is designed to provide users a seamless opportunity to gain key insights into the immediate state of biological pathways and cell state. Our platform aims to address many of the key challenges and bottlenecks with legacy proteomic solutions, such as mass spectrometry (“MS”), which include high instrument costs both in terms of acquisition and ownership, and complexity with data analysis, which together limit broad adoption. We believe our platform, which is designed to streamline sequencing and data analysis at a lower instrument cost and with greater automation than legacy proteomic solutions, could allow our product to have wide utility across the study of the proteome. For example, 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.

Restructuring

In November 2024, we announced that we committed to an organizational restructuring program designed to streamline and focus our overall corporate resources, as well as align required resources to focus on future product development objectives, including our recently announced Proteus™ platform. As a result, we terminated approximately 23% of our 187 employee workforce. In connection with the restructuring, we recognized one-time cash charges related to severance and other benefits of approximately $2.3 million in the fourth quarter of 2024. We may also incur additional costs not currently contemplated due to events that may occur as a result of, or that are associated with, the restructuring. Our restructuring

activities were complete as of December 31, 2024 and we do not expect to incur additional charges associated with these activities. For further information regarding our restructuring activities, please refer to Note 13. Restructuring.

Equity Transaction

On January 3, 2025, we entered into a securities purchase agreement with certain institutional investors pursuant to which we agreed to issue and sell, in a registered direct offering (the “Registered Direct Offering”) an aggregate of 15,625,000 shares of our Class A common stock at a price of $3.20 per share. The gross proceeds from the Registered Direct Offering were $50.0 million. After deducting estimated placement agents’ fees and other offering expenses payable by the Company, net proceeds recorded during the three months ended March 31, 2025 were approximately $46.8 million.

Total revenue for the sale of Platinum line of instruments, related reagent kits and service maintenance contracts increased $0.4 million, or 84.2%, for the three months ended March 31, 2025, as compared to the same period in 2024. The increase in revenue was due to higher sales volumes of instruments and consumables as we continue to improve our commercial sales execution.

Total cost of revenue increased $0.2 million, or 89.4%, for the three months ended March 31, 2025, as compared to the same period in 2024. The increase in cost of revenue is in line with the increase in year-over-year revenue.

Gross profit increased $0.2 million, or 80.7%, for the three months ended March 31, 2025, as compared to the same period in 2024.

Gross profit margin was 57.7% for the three months ended March 31, 2025, as compared to 58.9% for the same period in 2024. This change in margin was primarily based on the mix of products sold during each period and includes approximately a 7% and 10% benefit for the three months ended March 31, 2025 and 2024, respectively, for inventory utilized that was carried at low or no value that predates the commercial launch of our Platinum line of instruments. Our gross profit margin will continue to be impacted by this utilized inventory and has also been impacted and may continue to be impacted by inventory acquisition costs. We expect gross profit margin to be variable for the foreseeable future as we work through our continued commercialization efforts.

We began a controlled launch of the Platinum instrument and started to take orders in December 2022, and subsequently began a controlled commercial launch of Platinum in January 2023, and then moved to a full commercial launch of Platinum beginning in the second quarter of 2024. In January 2025, we announced the launch of our Platinum Pro benchtop sequencer. First shipments of Platinum Pro occurred in March 2025.

Net decrease in cash and cash equivalents	$	(11,948)	$	(80,697)

Net cash used in operating activities

For the three months ended March 31, 2025, net cash used in operating activities of $26.2 million was primarily due to a net loss of $19.2 million resulting from continued spend on research and development and commercialization efforts, net changes in operating assets and liabilities of $6.1 million, a change in fair value of warrant liabilities of $3.4 million, primarily driven by the change in the underlying trading price of our Class A common stock, and accretion on marketable securities of $2.1 million partially offset by stock-based compensation of $2.4 million, depreciation and amortization of $0.9 million and write-downs of inventory of $0.7 million.

For the three months ended March 31, 2024, net cash used in operating activities of $23.2 million was primarily due to a net loss of $19.5 million resulting from continued spend on research and development and commercialization efforts, net changes in operating assets and liabilities of $5.2 million and accretion on marketable securities of $2.1 million partially offset by stock-based compensation of $1.6 million and depreciation and amortization of $1.1 million.

Net cash used in investing activities

Table of Contents

For the three months ended March 31, 2025, net cash used in investing activities was $34.2 million compared to net cash used in investing activities of $57.4 million for the same period in 2024. This decrease in cash used was primarily due to a $64.3 million increase in cash provided by the sales and maturities of marketable securities partially offset by an increase in cash used to purchase marketable securities of $40.8 million.

Net cash provided by (used in) financing activities

For the three months ended March 31, 2025, net cash provided by financing activities was $48.4 million compared to cash used of $0.1 million for the same period in 2024. This increase in cash provided was due to $46.8 million of net proceeds from the Registered Direct Offering and $1.6 million of proceeds from the exercise of stock options. Further information regarding the Registered Direct Offering can be found below.

Liquidity Outlook

Since our inception, we have funded our 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. Additionally, we began to generate revenue during 2023 from commercial sales of our Platinum instrument. Our primary uses of liquidity have been operating expenses, capital expenditures and our acquisition of certain assets. Cash flows from operations have been historically negative as we continue to invest in the development of our technology in NGPS. Going forward, we anticipate debt or equity offerings will be the primary source of funds to support our operating needs and capital expenditures until we reach scale of our commercial operations. We expect to incur negative operating cash flows on an annual basis for the foreseeable future until such time that we can scale our revenue growth.

We expect that our existing cash and cash equivalents and investments in marketable securities, together with revenue from the sale of our products and services, will be sufficient to meet our liquidity, capital expenditure, and anticipated working capital requirements and fund our operations for at least the next 12 months. We expect to use our cash and cash equivalents and investments in marketable securities and funds from revenue generated to invest in our continued commercialization efforts, to further invest in research and development, for other operating expenses, business acquisitions and for working capital and general corporate purposes.

As of March 31, 2025, we had cash and cash equivalents and investments in marketable securities totaling $232.6 million. Our future capital requirements may vary from those currently planned and will depend on various factors including the pace and success of product commercialization.

Our ongoing commercialization of our Platinum line of instruments as well as our continuing research and development efforts to enhance our instruments may require an accelerated amount of spending to enhance the sales and marketing teams, continue to drive development, and build inventory. Other factors that could accelerate cash needs include: (i) delays in achieving scientific and technical milestones, (ii) unforeseen capital expenditures and fabrication costs related to manufacturing for commercialization, (iii) changes we may make in our business or commercialization strategy, (iv) costs of running a public company, (v) other items affecting our forecasted level of expenditures and use of cash resources, including potential acquisitions, and (vi) increased product and service costs.

On August 11, 2023, we filed a universal shelf registration statement on Form S-3 (the “Shelf Registration Statement”), which became effective on August 22, 2023, covering the offering of Class A common stock, preferred stock, debt securities, warrants, rights and units.

On December 11, 2024, we entered into an Equity Distribution Agreement (the “Sales Agreement”) with Canaccord Genuity LLC (“Canaccord”) to sell shares of our Class A common stock, par value $0.0001, having an aggregate offering price of up to $75.0 million, from time to time through an “at-the-market” offering program under which Canaccord will act as sales agent. We have no obligation to sell any shares under the Sales Agreement and may at any time suspend solicitation and offers under the EDA. The ATM Offering is being made pursuant to our shelf registration and a prospectus supplement related to the ATM Offering dated December 11, 2024. During the year ended December 31, 2024, we sold and issued 23,425,650 shares of our Class A common stock under the ATM Offering, resulting in gross proceeds of $36.2 million. Net proceeds were $34.8 million after commissions and issuance costs of $1.4 million. We sold no shares of our Class A common stock under the ATM Offering for the three months ended March 31, 2025.

shares of our Class A common stock at a price of $3.20 per Share. The gross proceeds from the Registered Direct Offering were $50.0 million. After deducting estimated placement agents’ fees and other offering expenses payable by the Company, net proceeds recorded during the three months ended March 31, 2025 were approximately $46.8 million.

In the future, we may be unable to obtain any required additional financing on terms favorable to us, if at all. If adequate funds are not available to us on acceptable terms or otherwise, we may be unable to successfully develop or enhance products and services, respond to competitive pressure or take advantage of acquisition opportunities, any of which could have a material adverse effect on our business, financial condition, operating results and cash flows.

Capital Expenditures

We forecast capital expenditures in order to execute on our business plan and maintain growth; however, the actual amount and timing of such capital expenditures will ultimately be determined by the volume of business. We anticipate our future capital expenditures will be at approximately the same level as compared to the year ended December 31, 2024. We have funded and plan to continue funding these capital expenditures with cash and financing.

Contractual Obligations

We lease certain facilities and equipment under noncancellable lease agreements that expire at various dates through 2032. As of March 31, 2025, future lease payments, before adjustments for tenant incentives, were approximately $25.6 million.

Licenses related to certain intellectual property

We license certain intellectual property, some of which may be utilized in our current or future product offerings. To preserve the right to use such intellectual property, we are required to make annual minimum fixed payments totaling approximately $0.2 million as well as royalties based on net sales if the royalties exceed annual minimum fixed payments.

Critical Accounting Policies and Significant Judgments and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our Condensed Consolidated Financial Statements, which have been prepared in accordance with U.S. GAAP. The preparation of these Condensed Consolidated Financial Statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the Condensed Consolidated Financial Statements, as well as expenses incurred during the reporting periods. Our estimates are based on historical experience and various other factors we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about items not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Please refer to our critical accounting policies as disclosed in our Annual Report on Form 10-K for the year ended December 31, 2024 and Note 2. Summary of Significant Accounting Policies, in the accompanying notes to the Condensed Consolidated Financial Statements for a complete description of our significant accounting policies.

Recently Issued Accounting Pronouncements

Please refer to Note 2. Summary of Significant Accounting Policies, in the accompanying notes to the Condensed Consolidated Financial Statements included elsewhere in this Quarterly Report on Form 10-Q for a description of recently issued accounting pronouncements that may potentially impact our financial position and results of operations.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Inflation risk

We believe inflation can and has had an impact on the underlying cost of our supplies and manufacturing components related to our business. To the extent our costs are impacted by general inflationary pressures, we may not be able to fully offset such higher costs through price increases or manufacturing efficiencies. Our inability or failure to do so could harm our business, financial condition, results of operations or cash flows.

Interest rate risk

Table of Contents

As of March 31, 2025, our marketable securities are comprised primarily of investments in money market funds backed by U.S. government issued securities, U.S. Treasury bills, and high-quality corporate commercial paper. The primary objective of our investments is the preservation of capital to fulfill liquidity needs. We do not enter into investments for trading or speculative purposes. Based on the short-term nature of our holdings, future interest rate changes are not expected to have a material impact on our marketable securities.

Foreign Currency Risk

Presently, we operate our business primarily within the United States, with limited sales outside the United States. To date, we have executed the majority of our transactions in U.S. dollars. In the future, we anticipate expanding into Europe and other locations outside the United States. This expansion may include transacting business in currencies other than the U.S. Dollar. Despite this, we anticipate conducting limited activity outside the U.S. Dollar in the near term, and therefore foreign currency translation risk is not expected to have a material impact on our Condensed Consolidated Financial Statements. However, the growth of our operations, scope of transactions outside the United States, and the use of currencies other than the U.S. Dollar may grow in the future, at which point it is possible foreign currency translation will have a material effect on our operations. To date, we have not entered into any hedging arrangements with respect to foreign currency risk. As our international operations grow, we will continue to reassess our approach to managing our risk relating to fluctuations in currency rates.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act.

Disclosure controls and procedures are controls and other procedures designed to ensure information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include controls and procedures designed to ensure information required to be disclosed in our reports filed under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure. Based on the evaluation of our disclosure controls and procedures, our Chief Executive Officer and Chief Financial Officer concluded our disclosure controls and procedures were effective as of March 31, 2025.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the quarter ended March 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS.

From time to time, the Company is engaged in legal proceedings in the ordinary course of business. For further information on the Company’s legal proceedings, please refer to Note 17. Commitments and Contingencies, in the notes to the Condensed Consolidated Financial Statements.

ITEM 1A. RISK FACTORS.

Our business, results of operations, financial condition and cash flows are subject to various risks and uncertainties including the risk factors described under the caption “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2024, as filed with the SEC on March 3, 2025, and the risk factor described below.

Our use of artificial intelligence and machine learning is subject to evolving laws and regulations and risks associated with unauthorized use, and may not result in the competitive advantages desired, all of which could expose us to competitive risk and legal liability.

We use artificial intelligence, machine learning and automated decision-making technologies (“AI”) to assist in the performance, efficiency, and speed of various functions at the Company, including, but not limited to, general and administrative activities and research and development.

The regulatory framework for AI is rapidly evolving as many federal, state and foreign government bodies and agencies have introduced or are currently considering additional laws and regulations for areas including but not limited to consumer protection and transparency, bias and discrimination, intellectual property, employment and use in regulated healthcare devices. Additionally, existing laws and regulations may be interpreted in ways that would affect the operation of AI at the Company. As a result, implementation standards and enforcement practices are likely to remain uncertain for the foreseeable future, and we cannot yet determine the impact future laws, regulations, standards, or market perception of their requirements may have on our business and may not always be able to anticipate how to respond to these laws or regulations. Further, the unauthorized use of AI tools can result in the exposure of sensitive data, including our intellectual property or trade secrets or the personal information of our employees, customers, or other business partners to unauthorized persons or to the public.

There can be no assurance that we will realize the desired or anticipated benefits from AI, or any at all. Our use of AI could result in additional compliance costs, regulatory investigations and actions, and lawsuits; and If as a result, we are unable to use AI, it could make our business less efficient, result in competitive disadvantages, and our business, financial condition, results of operations and cash flows could be adversely affected.
