Cautionary Note Regarding Forward-Looking Statements and Industry Data

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995, which involve risks and uncertainties. All statements other than statements of historical fact contained in this Quarterly Report are statements that could be deemed forward-looking statements, including without limitation any statements with respect to the plans, strategies and objectives of management for future operations; statements concerning product research, development and commercialization plans, timelines and anticipated results; statements of expectation or belief; statements with respect to clinical trials and studies; statements with respect to royalties and milestones; statements with respect to the therapeutic potential of drug candidates; expectations of revenue, expenses, earnings or losses from operations, or other financial results; and statements of assumptions underlying any of the foregoing. Without limiting the foregoing, the words such as “expect(s)”, “believe(s)”, “will”, “may”, “anticipate(s)”, “focus(es)”, “plans”, “mission”, “strategy”, “potential”, “estimate(s)”, “opportunity”, “intend”, “project”, “seek”, “should”, “would”, “likelihood”, and similar expressions, whether in the negative or affirmative, are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. Forward-looking statements may include, but are not limited to, statements about:

•the initiation, timing, progress and results of future preclinical studies and clinical trials, and our research and development program for emavusertib;

•our estimates of the period in which we anticipate that existing cash and cash equivalents will enable us to fund our current and planned operations;

•our ability to continue as a going concern;

•our ability to obtain additional financing;

•our ability to establish and maintain collaborations;

•our plans to develop and commercialize emavusertib;

•the timing or likelihood of regulatory filings and approvals;

•the implementation of our business model and strategic plans for our business, drug candidate and technology;

•our estimates regarding expenses, future revenue and capital requirements;

•developments and projections relating to our competitors and our industry;

•our commercialization, marketing and manufacturing capabilities and strategy;

•the rate and degree of market acceptance and clinical utility of our products;

•our ability to meet and continue meeting the listing standards of The Nasdaq Stock Market LLC (“Nasdaq”);

•our competitive position; and

•our intellectual property position.

Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of various factors. We therefore caution you against relying on any of these forward-looking statements. Important factors that could cause actual results to differ materially from those in these forward-looking statements include the factors discussed below under the heading “Risk Factor Summary” and the risk factors detailed further in Item 1A, “Risk Factors” of Part I of our Annual Report on Form 10-K for the year ended December 31, 2024, as supplemented by the risk factors discussed in Part II, Item 1A, “Risk Factors” of this Quarterly Report on Form 10-Q.

This report includes statistical and other industry and market data that we obtained from industry publications and research, surveys, and studies conducted by third parties as well as our own estimates. All of the market data used in this report involve a number of assumptions and limitations, and you are cautioned not to give undue weight to such data. Industry publications and third party research, surveys, and studies generally indicate that their information has been obtained from sources believed to be reliable, although they do not guarantee the accuracy or completeness of such information. Our estimates of the potential market opportunities for emavusertib include several key assumptions based on our industry knowledge, industry publications, third party research, and other surveys, which may be based on a small sample size and may fail to accurately reflect market opportunities. While we believe that our internal assumptions are reasonable, no independent source has verified such assumptions.

Table of Contents

The forward-looking statements included in this report represent our estimates as of the filing date of this report. We specifically disclaim any obligation to update these forward-looking statements in the future. These forward-looking statements should not be relied upon as representing our estimates or views as of any date subsequent to the date of this report.

Risk Factor Summary

Investment in our securities involves risk. You should carefully consider the following summary of what we believe to be the principal risks facing our business, in addition to the risks described more fully in Item 1A, “Risk Factors” of Part I of our Annual Report on Form 10-K for the year ended December 31, 2024, as supplemented by the risk factors discussed in Part II, Item 1A, “Risk Factors” of this Quarterly Report on Form 10-Q and other information included in this report. The risks and uncertainties described below are not the only risks and uncertainties we face. Additional risks and uncertainties not presently known to us or that we presently deem less significant may also impair our business operations.

If any of the following risks occurs, our business, financial condition, and results of operations and future growth prospects could be materially and adversely affected, and the actual outcomes of matters as to which forward-looking statements are made in this report could be materially different from those anticipated in such forward-looking statements.

•We have identified conditions and events that raise substantial doubt about our ability to continue as a going concern.

•We have incurred substantial losses, expect to continue to incur substantial losses for the foreseeable future and may never generate significant revenue or achieve or maintain profitability.

•We will require substantial additional capital, and if we are unable to raise capital when needed, we could be forced to delay, reduce or eliminate our drug development program or commercialization efforts, and our ability to continue operations could be adversely affected.

•We depend heavily on the success of emavusertib, which is still in early clinical development. Clinical trials of emavusertib may not be successful. If we are unable to commercialize emavusertib or experience significant delays in doing so, our business will be materially harmed.

•We have never obtained marketing approval for a drug candidate and we may be unable to obtain, or may be delayed in obtaining, marketing approval for emavusertib or any future drug candidates that we, or any future collaborators, may develop.

•We may not be successful in establishing additional strategic collaborations, which could adversely affect our ability to develop and commercialize emavusertib.

•We rely in part on third parties to conduct clinical trials of emavusertib and if such third parties perform inadequately, including failing to meet deadlines for the completion of such trials, research or testing, then we may not be able to successfully develop and commercialize emavusertib and grow our business.

•Even if we complete the necessary preclinical studies and clinical trials, the marketing approval process is expensive, time consuming and uncertain, which may prevent us or any future collaborators from obtaining approvals for the commercialization of emavusertib.

•We face substantial competition, and our competitors may discover, develop or commercialize drugs before or more successfully than we do.

•We may not be able to obtain and maintain patent protection for our technologies and drugs, our licensors may not be able to obtain and maintain patent protection for the technology or drugs that we license from them, and the patent protection we or they do obtain may not be sufficient to stop our competitors from using similar technology.

•Any allegation of an event of default under the Oberland Purchase Agreement could have a material adverse effect on our business, financial condition and stock price, including our ability to continue as a going concern.

•If we are not able to attract and retain key management and scientific personnel and advisors, we may not successfully develop emavusertib or achieve our other business objectives.

•We are not in compliance with the requirements for continued listing on the Nasdaq Capital Market. If we fail to regain and maintain compliance with Nasdaq’s requirements, our common stock could be delisted from trading, which would decrease the liquidity of our common stock and our ability to raise additional capital.

CURIS, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

(In thousands, except share and per share data)

1. Nature of Business

Curis, Inc. is a biotechnology company focused on the development of emavusertib (CA-4948), an orally available, small molecule inhibitor of Interleukin-1 receptor associated kinase, or IRAK4. Throughout these Condensed Consolidated Financial Statements, Curis, Inc. and its wholly owned subsidiaries are collectively referred to as the “Company” or “Curis”.

The Company is party to a collaboration agreement with Genentech Inc. (“Genentech”), a member of the Roche Group, under which Genentech and F. Hoffmann-La Roche Ltd (“Roche”) are commercializing Erivedge® (vismodegib), a first-in-class orally administered small molecule Hedgehog signaling pathway antagonist. Erivedge is approved for the treatment of advanced basal cell carcinoma (“BCC”).

The Company is party to an exclusive collaboration agreement with Aurigene Discovery Technologies Limited (“Aurigene”) for the discovery, development and commercialization of small molecule compounds in the areas of immuno-oncology and precision oncology, including emavusertib.

The Company is subject to risks common to companies in the biotechnology industry as well as risks that are specific to the Company’s business, including, but not limited to: the Company’s ability to obtain adequate financing to fund its operations; the Company’s ability to continue as a going concern; the Company’s ability to advance and expand its research and development program for emavusertib; the Company’s ability to establish strategic collaborations; the Company’s reliance on third parties to conduct clinical trials of emavusertib; the Company’s ability to execute on its overall business strategies; the Company’s ability to obtain and maintain necessary intellectual property protection; development by the Company’s competitors of new or better technological innovations; the Company’s ability to comply with regulatory requirements; the Company’s ability to obtain and maintain applicable regulatory approvals and commercialize any approved drug candidates; and the ability of the Company and its wholly owned subsidiary, Curis Royalty, LLC (“Curis Royalty”), to satisfy the terms of the royalty interest purchase agreement (the “Oberland Purchase Agreement”) with TPC Investments I LP and TPC Investments II LP (the “Purchasers”), each of which is a Delaware limited partnership managed by Oberland Capital Management, LLC, and Lind SA LLC (the “Agent”), a Delaware limited liability company managed by Oberland Capital Management, LLC, as collateral agent for the Purchasers.

The Company’s future operating results will largely depend on the progress of emavusertib and the magnitude of payments that it may receive and make under its current and potential future collaborations. The results of the Company’s operations have varied and will likely continue to vary significantly from year to year and quarter to quarter and depend on a number of factors, including, but not limited to the timing, outcome and cost of the Company’s preclinical studies and clinical trials for its drug candidate.

The Company will require substantial funds in the immediate term to maintain its research and development program and support operations. The Company has incurred losses and cash outflows from operations since its inception. The Company had an accumulated deficit of $1.3 billion as of June 30, 2025, and incurred a net loss of $19.2 million and used $15.3 million of cash in operations for the six months ended June 30, 2025. The Company expects to continue to generate operating losses in the foreseeable future.

In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (Subtopic 205-40), the Company has concluded there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the Condensed Consolidated Financial Statements are issued. Based on the Company's $10.1 million of existing cash and cash equivalents at June 30, 2025, together with the proceeds from the July 2025 Offerings, recurring losses and cash outflows from operations since inception, an expectation of continuing losses and cash outflows from operations for the foreseeable future and the need to raise substantial additional capital to finance the Company's future operations, the Company concluded it does not have sufficient cash on hand to support current operations within the next 12 months from the date of filing this Quarterly Report on Form 10-Q. These factors raise substantial doubt regarding the Company’s ability to continue as a going concern.

The Company plans to seek additional funding through a number of potential avenues, including private or public equity financings, collaborations, or other strategic transactions. The Company has faced and expects to continue to face substantial difficulty in raising capital. The Company may not be able to obtain funding on acceptable terms, or at all. The terms of any financing may adversely affect the holdings or the rights of the Company’s stockholders. The Company’s ability to raise

Table of Contents

additional funds will depend on, among other factors, financial, economic and market conditions, as well as maintaining the Company's listing on Nasdaq, many of which are outside of its control, and it may be unable to raise financing when needed, or on terms favorable to the Company. If necessary funds are not available, the Company will have to delay, reduce the scope of, or eliminate its development of emavusertib, potentially delaying the time to market for or preventing the marketing of emavusertib, which would have a material adverse effect on the Company’s operations and future prospects. If the Company is unable to obtain sufficient capital, the Company would be unable to fund its operations and may be required to evaluate alternatives, which could include dissolving and liquidating its assets or seeking protection under the bankruptcy laws, and a determination to file for bankruptcy could occur at a time that is earlier than when the Company would otherwise exhaust its cash resources. If the Company decides to dissolve and liquidate its assets or to seek protection under the bankruptcy laws, it is unclear to what extent the Company would be able to pay its obligations, and, accordingly, it is further unclear whether and to what extent any resources would be available for distributions to stockholders.

2. Summary of Significant Accounting Policies

(a)Basis of Presentation and Principles of Consolidation

The accompanying Condensed Consolidated Financial Statements have been prepared in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. These statements, however, are condensed and do not include all disclosures required by accounting principles generally accepted in the U.S. (“GAAP”) for complete financial statements and should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 as filed with the Securities and Exchange Commission (“SEC”) on March 31, 2025.

In the opinion of the management of the Company, the unaudited Condensed Consolidated Financial Statements contain all adjustments (all of which were considered normal and recurring) necessary for a fair statement of the Company’s financial position at June 30, 2025; the results of operations for the three and six-month periods ended June 30, 2025 and 2024; stockholders' equity (deficit) for the three and six-month periods ended June 30, 2025 and 2024; and the cash flows for the six-month periods ended June 30, 2025 and 2024. The Condensed Consolidated Balance Sheet at December 31, 2024 was derived from audited annual financial statements but does not contain all of the footnote disclosures from the annual financial statements.

The Company’s Condensed Consolidated Financial Statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. In accordance with FASB ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (Subtopic 205-40), the Company has concluded there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the Condensed Consolidated Financial Statements are issued. The Condensed Consolidated Financial Statements do not include any adjustments that might result from the outcome of this uncertainty.

The preparation of the Company’s Condensed Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and disclosure of revenue, expenses and certain assets and liabilities at the balance sheet date. Such estimates include the performance obligations under the Company’s collaboration agreements; the collectability of receivables; and the value of certain liabilities. Actual results may differ from such estimates. These interim results are not necessarily indicative of results to be expected for a full year or subsequent interim periods.

Cash equivalents consist of highly liquid investments purchased with original maturities of three months or less.

The Company classified $0.5 million of its cash as restricted cash as of both June 30, 2025 and December 31, 2024. These amounts represent the security deposit associated with the Company’s Lexington, Massachusetts headquarters.

(d)Leases

The Company determines if an arrangement is a lease at contract inception. The Company made an accounting policy election to not recognize leases with an initial term of 12 months or less within its Condensed Consolidated Balance Sheets and to recognize those lease payments on a straight-line basis in its Condensed Consolidated Statements of Operations and Comprehensive Loss over the lease term. Operating lease assets represent the Company's right to use an underlying asset for the lease term and operating lease liabilities represent its obligation to make lease payments arising from the lease. Operating lease assets and liabilities are recognized at the commencement date of the lease based upon the present value of lease payments over

Table of Contents

the lease term. When determining the lease term, the Company includes options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option.

As the Company's lease does not provide an implicit interest rate, the Company uses its incremental borrowing rate, which is based on rates that would be incurred to borrow on a collateralized basis over a term equal to the lease payments in a similar economic environment, in determining the present value of lease payments.

The lease payments used to determine the operating lease asset may include lease incentives and stated rent increases and are recognized as an operating lease right-of-use asset in the Condensed Consolidated Balance Sheets. The Company's lease agreements may include both lease and non-lease components, which may be accounted for as a single lease component when the payments are fixed. Variable payments included in the lease agreement are expensed as incurred.

The Company's operating lease is reflected in operating lease right-of-use asset and operating lease liability in the Condensed Consolidated Balance Sheets. Lease expense for lease payments is recognized on a straight-line basis over the lease term.

(e)Other Assets

Other assets consist of long-term prepayments and deposits.

(f)Revenue Recognition

The Company applies the revenue recognition guidance in accordance with FASB Codification Topic 606, Revenue from Contracts with Customers.

The Company recognizes royalty revenues related to Genentech’s and Roche’s sales of Erivedge. For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and where the license is deemed to be the predominant item to which the royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur, or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). The Company expects to continue recognizing royalty revenue from Genentech’s sales of Erivedge in the U.S. and Roche's sales of Erivedge outside of the U.S. (see Note 7, Research and Development Collaborations). However, a significant portion of Erivedge royalties will be paid to the Purchasers pursuant to the Oberland Purchase Agreement (see Note 6, Liability Related to the Sale of Future Royalties).

(g)Segment Reporting

The Company has determined that it operates in a single reportable segment, which is the research and development of innovative drug candidates for the treatment of human cancer.

(h)New Accounting Pronouncements

Issued, Not Yet Adopted

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires disclosure of disaggregated income taxes paid, prescribes standard categories for the components of the effective tax rate reconciliation, and modifies other income tax-related disclosures. ASU No. 2023-09 is effective for fiscal years beginning after December 15, 2024 and allows for adoption on a prospective basis, with a retrospective option. Early adoption is permitted. The Company is currently evaluating the impact of the ASU on the income tax disclosures within the Consolidated Financial Statements.

In November 2024, the FASB issued ASU-2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Topic 220): Disaggregation of Income Statement Expenses. The ASU requires additional disclosures of the nature of the expenses included in the income statement, including disaggregation of the expense captions presented on the Consolidated Statements of Operations into specific categories. ASU No. 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027 and allows for adoption on a prospective basis, with a retrospective option. Early adoption is permitted. The Company is currently evaluating the impact of the ASU on the Condensed Consolidated Financial Statement disclosures.

In July 2025, the One Big Beautiful Bill Act (“OBBB”) was enacted in the U.S. The OBBB includes significant provisions, such as the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, restoration of favorable tax treatment for certain business provisions including the expensing of domestic research and development expenditures, and modifications to the international tax framework. Certain provisions will take effect beginning in 2026, while others apply retroactively to January 1, 2025. The Company is currently evaluating the impact on the income tax disclosures within the Consolidated Financial Statements.

3. Fair Value of Financial Instruments

The Company applies the provisions of FASB Codification 820, Fair Value Measurements (“ASC 820”) for its financial assets and liabilities that are re-measured and reported at fair value each reporting period and the non-financial assets and liabilities that are re-measured and reported at fair value on a non-recurring basis. Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining fair value, the Company considers the principal or most advantageous market in which it would transact and considers assumptions that market participants would use when pricing the asset or liability. ASC 820 establishes a three-level valuation hierarchy for disclosure of fair value measurements. Financial assets and liabilities are categorized within the valuation hierarchy based upon the lowest level of input that is significant to the measurement of fair value. The three levels of the hierarchy are defined as follows:


Level 1			Quoted prices in active markets for identical assets or liabilities.

Level 2			Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3			Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

In accordance with the fair value hierarchy, the following tables show the fair value as of June 30, 2025 and December 31, 2024 of those financial assets that are measured at fair value on a recurring basis, according to the valuation techniques the Company used to determine their fair value.

Table of Contents

As of June 30, 2025, the Company had an operating lease liability of $2.3 million and related right-of-use asset of $2.5 million related to its operating lease. As of December 31, 2024, the Company had an operating lease liability of $3.0 million and related right-of-use asset of $3.2 million related to its operating lease.

The Company recorded lease cost of $0.4 million for each of the three months ended June 30, 2025 and 2024. The Company recorded lease cost of $0.7 million and $0.8 million during the six months ended June 30, 2025 and 2024, respectively. The Company paid $0.4 million in rent during each of the three months ended June 30, 2025 and 2024. The Company paid $0.8 million in rent during each of the six months ended June 30, 2025 and 2024. The discount rate associated with the Company’s right-of-use asset is 10%.

6. Liability Related to the Sale of Future Royalties

In March 2019, the Company and Curis Royalty entered into the Oberland Purchase Agreement with the Purchasers and Agent. The Company sold to the Purchasers a substantial portion of its rights to receive royalties from Genentech on potential net sales of Erivedge. As upfront consideration for the purchase of the royalty rights, the Purchasers paid to Curis Royalty $65.0 million less certain transaction expenses.

The Oberland Purchase Agreement provides that after the occurrence of an event of default as defined under the security agreement by Curis Royalty, the Purchasers shall have the option, for a period of 180 days, to require Curis Royalty to repurchase a portion of certain royalty and royalty related payments, excluding a portion of non-U.S. royalties retained by Curis Royalty (referred to as the “Purchased Receivables”), at a price (referred to as the “Put/Call Price”), equal to 250% of the sum of the upfront purchase price and any portion of the milestone payments paid in a lump sum by the Purchasers, if any, minus certain payments previously received by the Purchasers with respect to the Purchased Receivables. The Company concluded that this put option is an embedded derivative that requires bifurcation from the deferred royalty obligation and evaluates the fair value of the put option each reporting period. The estimated fair value of the put option is immaterial as of June 30, 2025 and December 31, 2024. Additionally, Curis Royalty shall have the option at any time to repurchase the Purchased Receivables at the Put/Call Price as of the date of such repurchase. No events of default have occurred as of June 30, 2025.

As a result of the obligation to pay future royalties to the Purchasers, the Company recorded the proceeds as a liability on its Condensed Consolidated Balance Sheets. It accounts for the liability and interest expense using the interest method over the expected life of the Oberland Purchase Agreement. As a result, the Company imputes interest on the transaction and records imputed interest expense at the estimated interest rate. The Company’s estimate of the interest rate under the Oberland Purchase Agreement is based on the amount of royalty payments expected to be received by the Purchasers over the life of the Oberland Purchase Agreement. The projected amount of royalty payments expected to be paid to the Purchasers involves the use of significant estimates and assumptions with respect to the revenue growth rate in the Company’s projections of sales of Erivedge. The Company periodically assesses the expected royalty payments to Curis Royalty from Genentech using a combination of historical results and forecasts from market data sources. To the extent such payments are greater or less than the current estimates or the timing of such payments is materially different than the original estimates, the Company prospectively adjusts the amortization of the liability.

The Company determined the fair value of the liability related to the sale of future royalties at the time of the Oberland Purchase Agreement to be $65.0 million, with a current effective annual imputed interest rate of 6.1%. The Company incurred $0.6 million of transaction costs in connection with the Oberland Purchase Agreement. These transaction costs are being amortized to imputed interest expense over the estimated term of the Oberland Purchase Agreement. The carrying value of the liability related to the sale of future royalties approximates fair value as of June 30, 2025 and is based on the Company’s current estimates of future royalties expected to be paid to the Purchasers over the life of the arrangement, which are considered Level 3 inputs.

The following table shows the activity with respect to the liability related to the sale of future royalties during the six months ended June 30, 2025.

7. Research and Development Collaborations

(a)Genentech

In June 2003, the Company licensed its proprietary Hedgehog pathway antagonist technologies to Genentech for human therapeutic use. Erivedge is being commercialized by Genentech in the U.S. and by Genentech’s parent company, Roche, outside of the U.S. for the treatment of advanced BCC.

Pursuant to the collaboration agreement, the Company is entitled to a royalty on net sales of Erivedge that ranges from 5% to 7.5%. The royalty rate applicable to Erivedge may be decreased by 2% on a country-by-country basis in certain specified circumstances. Cost of royalties comprises payments to university licensors and was not material for each of the three and six months ended June 30, 2025 and 2024.

The Company had account receivables from Genentech under this collaboration of $2.8 million and $3.3 million as of June 30, 2025 and December 31, 2024, respectively, in its Condensed Consolidated Balance Sheets.

As previously discussed in Note 6, Liability Related to the Sale of Future Royalties, a significant portion of royalty revenues received from Genentech on net sales of Erivedge will be paid to the Purchasers pursuant to the Oberland Purchase Agreement.

9. Stock Plans and Stock-Based Compensation

As of June 30, 2025, the Company had two stockholder-approved, stock-based compensation plans: (i) the Fifth Amended and Restated 2010 Stock Incentive Plan, as amended (“2010 Plan”) and (ii) the Amended and Restated 2010 Employee Stock Purchase Plan (“ESPP”). New employees are generally issued options as an inducement equity award under Nasdaq Listing Rule 5635(c)(4) outside of the 2010 Plan (“Inducement Awards”).

The Fifth Amended and Restated 2010 Stock Incentive Plan

The 2010 Plan permits the granting of incentive and non-qualified stock options and stock awards to employees, officers, directors, and consultants of the Company and its subsidiaries at prices determined by the Company’s board of directors. In May 2025, the Company's stockholders approved an amendment to the 2010 Plan to reserve an additional 1,255,000 shares of common stock for issuance under the 2010 Plan. The Company can issue up to 3,356,600 shares of its common stock pursuant to awards granted under the 2010 Plan. Options vest and become exercisable based on a schedule determined by the board of directors and expire up to ten years from the date of grant. The 2010 Plan uses a “fungible share” concept under which each share of stock subject to awards granted as options and stock appreciation rights (“SARs”) will cause one share per share under the award to be removed from the available share pool, while each share of stock subject to awards granted as restricted stock, restricted stock units, other stock-based awards or performance awards where the price charged for the award is less than 100% of the fair market value of the Company’s common stock will cause 1.3 shares per share under the award to be removed from the available share pool.

As of June 30, 2025, the Company granted options to employees, executive officers, and non-employee directors with an exercise price equal to the closing price of the Company's common stock on the grant date. The Company granted employees restricted stock awards ("RSAs") and restricted stock units ("RSUs") at no cost. As of June 30, 2025, 707,694 shares remained available for grant under the 2010 Plan.

During the six months ended June 30, 2025, the Company’s board of directors granted options to purchase 1,108,400 shares of the Company’s common stock to executive officers and employees of the Company under the 2010 Plan. These options vest and become exercisable as to 25% of the shares underlying the award after the first year and as to an additional

Table of Contents

6.25% of the shares underlying the award in each subsequent quarter, based upon continued employment over a four year period.

During the six months ended June 30, 2025, the Company’s board of directors granted 350,600 RSUs to employees of the Company under the 2010 Plan. These RSUs vest and become exercisable as to 25% of the shares underlying the award annually on the date of grant, based upon continued employment over a four year period.

During the six months ended June 30, 2025, the Company’s board of directors granted options to its non-employee directors to purchase 80,000 shares of common stock under the 2010 Plan, which will vest and become exercisable one year from the date of grant.

Inducement Awards

The Company grants Inducement Awards to certain new employees. These options generally vest as to 25% of the shares underlying the option on the first anniversary of the grant date, and as to an additional 6.25% of the shares underlying the option on each successive quarter thereafter. During the six months ended June 30, 2025, the Company’s board of directors granted Inducement Awards to purchase 200,000 shares of common stock. These options were granted at an exercise price that equaled the closing market price of the Company’s common stock on the grant date.

Stock Options

A summary of stock option activity under the 2010 Plan and Inducement Awards are summarized as follows:


	Number of Shares	Weighted Average Exercise Price per Share		Weighted Average Remaining Contractual Life	Aggregate Intrinsic Value

Expected term (years)	6.0	6.0


Risk free interest rate	3.9% - 4.4%	3.9% - 4.3%
Expected volatility	113% - 114%	114% - 116%
Expected dividends	None	None

As of June 30, 2025, there was $6.0 million of unrecognized compensation cost related to unvested employee stock option awards outstanding, which is expected to be recognized as expense over a weighted average period of 2.6 years. There were no employee stock options exercised during each of the six months ended June 30, 2025 and 2024.

As of June 30, 2025, there was $0.8 million of unrecognized compensation costs related to RSUs, which are expected to be recognized as expense over a remaining weighted average period of 3.6 years.

Amended and Restated 2010 Employee Stock Purchase Plan

The Company has reserved 500,000 shares of common stock for issuance under the ESPP. Eligible employees may purchase shares of the Company’s common stock at 85% of the lower closing market price of the common stock at the beginning of the enrollment period or ending date of the purchase period within a two-year enrollment period, as defined. The Company has four six-month purchase periods per each two-year enrollment period. If, within any one of the four purchase periods in an enrollment period, the purchase period ending stock price is lower than the stock price at the beginning of the enrollment period, the two-year enrollment resets at the new lower stock price. During the three and six months ended June 30, 2025, 36,649 shares were issued under the ESPP. During the three and six months ended June 30, 2024, 11,307 shares were issued under the ESPP. As of June 30, 2025, there were 357,814 shares available for future purchase under the ESPP.

Stock-Based Compensation Expense

For the three and six months ended June 30, 2025 and 2024, the Company recorded stock-based compensation expense to the following line items in its costs and expenses section of the Condensed Consolidated Statements of Operations and Comprehensive Loss:


	Three Months Ended June 30,				Six Months Ended June 30,
(in thousands)	2025		2024		2025		2024

10. Loss Per Common Share

Basic and diluted loss per common share is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net loss per common share is the same as basic net loss per common share for the three and six months ended June 30, 2025 and 2024, because the effect of adjusting the weighted average number of common shares outstanding during the period for the potential dilutive effect of common stock equivalents would be antidilutive due to the Company’s net loss position for these periods. The 1,961,754 shares of common stock underlying the outstanding March 2025 Pre-Funded Warrants have been included in the weighted-average number of shares of common stock used to calculate net loss per share, basic and diluted, attributable to common stockholders because the shares may be issued for little or no consideration, they are fully vested, and the March 2025 Pre-Funded Warrants are immediately exercisable upon their issuance date.

The following common stock equivalents were excluded from the calculation of diluted net loss per share applicable to common stockholders for the periods indicated because including them would have had an anti-dilutive effect:


	As of June 30,
	2025	2024
Anti-dilutive common stock equivalents:
October 2024 Common Warrants	2,398,414	—
March 2025 Common Warrants	8,316,882	—
Stock options outstanding	2,426,530	1,226,714
Unvested RSAs	—	40,137
Unvested RSUs	283,500	—
Total anti-dilutive common stock equivalents	13,425,326	1,266,851

11. Segment Information

The Company has determined that it operates in a single reportable segment, which is the research and development of innovative drug candidates for the treatment of human cancer. Resources are allocated and performance is assessed by the Company's President and Chief Executive Officer, whom the Company has determined to be its Chief Operating Decision Maker (CODM).

The CODM considers actual operating results on an annual basis on a consolidated basis, including consolidated net loss, when making decisions about allocating capital and personnel to the segment in the annual budgeting and forecasting process, which includes comparison of budget to actual and current period to prior period variances. The CODM assesses performance for the operating segment and decides, in part, how to allocate resources based on net loss that also is reported on the Condensed Consolidated Statement of Operations as net loss. The measure of segment assets is reported on the Condensed Consolidated Balance Sheets as total assets.

In addition to the significant categories included within net loss presented on the Company's Condensed Consolidated Statement of Operations, the following table is representative of the significant expense categories for the three and six months ended June 30, 2025 and 2024, including a reconciliation to Net loss:


	Three Months Ended June 30,				Six Months Ended June 30,
	2025		2024		2025		2024
Revenues, net	$	2,749	$	2,546	$	5,129	$	4,632

Overview

We are a biotechnology company focused on the development of emavusertib (CA-4948), an orally available, small molecule inhibitor of Interleukin-1 receptor associated kinase, or IRAK4. Emavusertib is currently being evaluated in the TakeAim Lymphoma Phase 1/2 study (CA-4948-101) in patients with relapsed/refractory primary central nervous system lymphoma, or PCNSL, in combination with the BTK inhibitor ibrutinib, as a monotherapy in the TakeAim Leukemia Phase 1/2 study (CA-4948-102) in patients with relapsed/refractory, or R/R, acute myeloid leukemia, or AML, and R/R high risk myelodysplastic syndrome, or hrMDS, and as a frontline combination therapy with venetoclax and azacitidine in patents with AML (CA-4948-104). Emavusertib has received Orphan Drug Designation from the U.S. Food and Drug Administration, or FDA, for the treatment of PCNSL, AML and MDS and from the European Commission for the treatment of PCNSL. We, through our 2015 collaboration with Aurigene Discovery Technologies Limited, or Aurigene, have the exclusive license to emavusertib (CA-4948). We licensed our rights to Erivedge® to Genentech, Inc, or Genentech, a member of the Roche Group, under which Genentech is commercializing Erivedge® for the treatment of advanced basal cell carcinoma.

Emavusertib

We are focused on the development of emavusertib, an orally available, small molecule inhibitor of IRAK4. IRAK4 plays an essential role in the toll-like receptor, or TLR, and interleukin-1 receptor, or IL-1R, signaling pathways, which are frequently dysregulated in patients with cancer. TLRs and the IL-1R family signal through the adaptor protein Myeloid Differentiation Primary Response Protein 88, which results in the assembly and activation of IRAK4, initiating a signaling cascade that induces cytokine and survival factor expression mediated by the NF-κB protein complex. Many B-cell leukemias and lymphomas are associated with constitutive activation of the NF-κB protein complex, which contributes to these cancers' proliferation and survival. The B-cell receptor, or BCR, and TLR pathways drive NF-κB activation. Preclinical studies have demonstrated that targeting both the BCR and TLR pathways is more synergistic than targeting either pathway alone. Similarly, preclinical studies targeting IRAKi in combination with FMS‐like tyrosine kinase 3, or FLT3, have demonstrated the ability to overcome the adaptive resistance incurred when targeting FLT3 alone. In AML patient derived xenografts, emavusertib has shown monotherapy anti-tumor activity as well as synergy with both venetoclax and azacitidine. In the clinic, emavusertib has shown anti-tumor activity across a broad range of hematologic malignancies, including monotherapy activity in AML, particularly those with a FLT3 mutation. In non-Hodgkin's lymphoma patients, particularly in PCNSL, emavusertib has shown anti-tumor activity in combination with a Bruton Tyrosine Kinase, or BTK, inhibitor.

TakeAim Lymphoma

Emavusertib is currently undergoing testing in combination with ibrutinib, a BTK inhibitor, in a Phase 1/2 open-label, single arm expansion trial in patients with R/R PCNSL (NCT03328078), also known as the TakeAim Lymphoma Phase 1/2 study. In June 2022 and December 2023, we provided preliminary clinical data for patients with various hematological malignancies in the combination portion of the ongoing TakeAim Lymphoma Phase 1/2 study. In December 2023, we provided clinical and safety data of emavusertib in combination with ibrutinib in several non-Hodgkin's lymphoma subtypes, including PCNSL patients. In July and December 2024, emavusertib was granted Orphan Drug Designation by the European Commission and the FDA, respectively, for the treatment of patients with PCNSL. In September 2024 and March 2025, we provided additional clinical data of emavusertib in combination with ibrutinib in R/R PCNSL. In March 2025, we announced that we had completed productive meetings with both the European Committee for Medicinal Products for Human Use, or CHMP, and the FDA on the suitability of using the ongoing TakeAim Lymphoma Phase 1/2 study to support a potential accelerated regulatory path for a Conditional Marketing Authorization, or CMA, submission in Europe and a New Drug Application, or NDA, submission in the U.S. We expect additional data from this study in the fourth quarter of 2025.

TakeAim Leukemia

In addition to the TakeAim Lymphoma Phase 1/2 study, emavusertib is currently undergoing testing in a Phase 1/2 open-label, single arm expansion trial in patients with R/R AML and hrMDS (NCT04278768), also known as the TakeAim Leukemia Phase 1/2 study. In January and December 2022, July and December 2023, and May and December 2024, we presented clinical data for patients from the ongoing TakeAim Leukemia Phase 1/2 study. Enrollment in the TakeAim Leukemia study is substantially complete.

AML Triplet Study

We have initiated a Phase 1 clinical study of emavusertib as an add-on agent to the combination of venetoclax and azacitidine in AML (2023-505828-58), which we refer to as the AML Triplet study. The AML Triplet study is currently being conducted in Spain, Germany, and Italy. The study is assessing the safety and tolerability of different dosing regimens of emavusertib in the triple combination in patients who achieved a complete remission on venetoclax and azacitidine, while remaining positive for minimal residual disease. We are continuing to evaluate different dosing regimens of emavusertib, venetoclax, and azacitidine.

Our Collaborations and License Agreements

We are party to a collaboration agreement with Genentech, a member of the Roche Group, under which Genentech and F. Hoffmann-La Roche Ltd, or Roche, are commercializing Erivedge® (vismodegib), a first-in-class orally administered small molecule Hedgehog signaling pathway antagonist. Erivedge is approved for the treatment of advanced basal cell carcinoma, or BCC.

In January 2015, we entered into an exclusive collaboration agreement with Aurigene, which was amended in September 2016, February 2020, and September 2024, for the discovery, development and commercialization of small molecule compounds in the areas of immuno-oncology and precision oncology worldwide, except for India and Russia, which are territories retained by Aurigene. We currently have licensed the IRAK4 (including emavusertib), PD1/TIM3, and the immuno-oncology programs under the Aurigene collaboration.

For further information regarding our collaboration and license agreements, refer to Note 7, Research and Development Collaborations, in the accompanying Notes to the Condensed Consolidated Financial Statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q and Note 10, Research and Development Collaborations, in Item 8 of Part II of our Annual Report on Form 10-K for the year ended December 31, 2024 as filed with the Securities and Exchange Commission, or SEC, on March 31, 2025.

Liquidity and Events that Raise Substantial Doubt About Our Ability to Continue as a Going Concern

Since our inception, we have funded our operations primarily through private and public placements of our equity securities, license fees, contingent cash payments, royalties and research and development funding from our corporate collaborators, and the monetization of certain royalty rights. We have never been profitable on an annual basis and had an accumulated deficit of $1.3 billion as of June 30, 2025. For the six months ended June 30, 2025, we incurred a net loss of $19.2 million and used $15.3 million of cash in operations.

We expect to continue to generate operating losses in the foreseeable future. In July 2025, we completed a registered direct offering and concurrent private placement, or July 2025 Offerings, for net proceeds of approximately $6.0 million. Based upon our current operating plan, we believe that our $10.1 million of existing cash and cash equivalents as of June 30, 2025, together with the proceeds from the July 2025 Offerings, should enable us to fund our existing operations into the first quarter of 2026. We have based this assessment on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect. Our current cash and cash equivalents are not expected to fund our operations beyond 12 months from the date of filing this Quarterly Report on Form 10-Q. We will require substantial additional funds in the immediate term to maintain our research and development program and support operations. See “Liquidity and Capital Resources—Funding Requirements” below and Note 1, Nature of Business, in the accompanying Notes to the Condensed Consolidated Financial Statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q for a further discussion of our liquidity and the conditions and events that raise substantial doubt regarding our ability to continue as a going concern.

We will need to generate significant revenues to achieve profitability, and do not expect to achieve profitability in the foreseeable future, if at all. We will require substantial additional funding in the immediate term to fund the development of emavusertib through regulatory approval and commercialization, and to support our continued operations. We will need to seek additional funding through a number of potential avenues, including private or public equity financings, collaborations, or other strategic transactions. Our ability to raise additional funds will depend on, among other factors, financial, economic and market conditions, as well as maintaining our listing on Nasdaq, many of which are outside of our control, and we may be unable to raise financing when needed, or on terms favorable to us. We have faced and expect to continue to face substantial difficulty in raising capital. If sufficient funds are not available, we will have to delay, reduce the scope of, or eliminate our research and

development program for emavusertib, including related clinical trials and operating expenses, potentially delaying the time to market for or preventing the marketing of emavusertib, which could adversely affect our business prospects and our ability to continue our operations, and would have a negative impact on our financial condition and ability to pursue our business strategies. In addition, we may seek to engage in one or more strategic alternatives, such as a strategic partnership with one or more parties, the licensing, sale or divestiture of some of our assets or proprietary technologies or the sale of our company, but there can be no assurance that we would be able to enter into such a transaction or transactions on a timely basis or on terms favorable to us, or at all. If we are unable to obtain sufficient capital, we would be unable to fund our operations and may be required to evaluate alternatives, which could include dissolving and liquidating our assets or seeking protection under the bankruptcy laws, and a determination to file for bankruptcy could occur at a time that is earlier than when we would otherwise exhaust our cash resources. If we decide to dissolve and liquidate our assets or to seek protection under the bankruptcy laws, it is unclear to what extent we would be able to pay our obligations, and, accordingly, it is further unclear whether and to what extent any resources would be available for distributions to stockholders.

Key Drivers

We believe that near term key drivers to our success will include:

•our ability to focus and successfully plan and execute current and planned clinical trials for emavusertib, and for such clinical trials to generate favorable data;

•our ability to raise additional financing to fund operations; and/or

•our ability to collaborate or license emavusertib and to successfully develop and commercialize emavusertib.

Financial Operations Overview

General. Our future operating results will largely depend on the progress of emavusertib. The results of our operations will vary significantly from year to year and quarter to quarter and depend on, among other factors, the cost and outcome of any preclinical development or clinical trials then being conducted. For a discussion of our liquidity and funding requirements, see “Liquidity and Events that Raise Substantial Doubt About Our Ability to Continue as a Going Concern” and “Liquidity and Capital Resources - Funding Requirements”.

Liability Related to the Sale of Future Royalties. In March 2019, we and our wholly owned subsidiary, Curis Royalty LLC, or Curis Royalty, entered into the royalty interest purchase agreement, or the Oberland Purchase Agreement, with entities managed by Oberland Capital Management, LLC, or the Purchasers, and Lind SA LLC, as collateral agent for the Purchasers, or Agent. Pursuant to the Oberland Purchase Agreement, the Purchasers acquired the rights to a portion of certain royalty and royalty-related payments excluding a portion of non-U.S. royalties retained by Curis Royalty, referred to as the Purchased Receivables, owed by Genentech under our collaboration agreement with Genentech. Upon closing of the Oberland Purchase Agreement, Curis Royalty received proceeds of $65.0 million, less certain transaction costs, from the Purchasers.

Revenue. We do not expect to generate any revenues from our direct sale of products for several years, if ever. Substantially all of our revenues to date have been derived from license fees, research and development payments, and other amounts that we have received from our strategic collaborators and licensees, including royalty payments. Our only source of revenues and/or cash flows from operations for the foreseeable future will be royalty payments that are contingent upon the continued commercialization of Erivedge under our collaboration with Genentech. We recognize royalty revenues related to Genentech’s sales of Erivedge and we expect to continue to recognize royalty revenue in future quarters from Genentech’s sales of Erivedge in the U.S. and Roche’s sales of Erivedge outside of the U.S. However, a significant portion of our royalty and royalty-related revenues under our collaboration with Genentech will be paid to the Purchasers, pursuant to the Oberland Purchase Agreement. The Oberland Purchase Agreement will terminate upon the earlier to occur of (i) the date on which Curis Royalty’s rights to receive the Purchased Receivables owed by Genentech under the Genentech collaboration agreement have terminated in their entirety or (ii) the date on which payment in full of the price equal to 250% of the sum of the upfront purchase price and any portion of the milestone payments paid in a lump sum by the Purchasers, if any, minus certain payments previously received by the Purchasers with respect to the Purchased Receivables, or the Put/Call Price, is received by the Purchasers pursuant to the Purchasers’ exercise of their put option or Curis Royalty’s exercise of its call right. For additional information regarding the Oberland Purchase Agreement, see Note 6, Liability Related to the Sale of Future Royalties, in the accompanying Notes to the Condensed Consolidated Financial Statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q.

Research and Development. Research and development expense primarily consists of costs incurred to develop emavusertib. These expenses consist primarily of:

•salaries and related expenses for personnel, including stock-based compensation expense;

Table of Contents

•costs of conducting clinical trials, including amounts paid to clinical centers, clinical research organizations and consultants, among others;

•other outside service costs, including regulatory costs and costs for contract manufacturing;

•the cost of companion drugs;

•facility costs; and

•certain payments that we make to Aurigene under our collaboration agreement, including, for example, milestone payments.

We expense research and development costs as incurred.

Research and development activities are central to our business model. Drug candidates in later stages of clinical development generally have higher development costs than those in earlier stages, primarily due to the increased size and duration of later-stage clinical trials. As a result, we expect that our research and development expenses will increase substantially over the next several years as we conduct larger clinical trials of emavusertib; prepare regulatory filings for emavusertib; continue to develop additional drug candidates; and potentially advance our drug candidates into later stages of clinical development.

The successful development and commercialization of emavusertib is highly uncertain. At this time, we cannot reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to complete the preclinical and clinical development of emavusertib. This uncertainty is due to the numerous risks and uncertainties associated with product development and commercialization, including the uncertainty of:

•our ability to successfully enroll our current and future clinical trials and our ability to initiate future clinical trials;

•the scope, quality of data, rate of progress and cost of clinical trials and other research and development activities undertaken by us or our collaborators;

•the cost and timing of regulatory approvals and maintaining compliance with regulatory requirements;

•the results of future preclinical studies and clinical trials;

•the cost of establishing clinical and commercial supplies of emavusertib and any products that we may develop;

•the cost and timing of establishing sales, marketing and distribution capabilities;

•our ability to become and remain profitable, which requires that we, either alone or with collaborators, must develop and eventually commercialize emavusertib with significant market potential and successfully launch a product for commercial sale;

•the effect of competing technological and market developments; and

•the cost and effectiveness of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights.

Any changes in the outcome of any of these variables with respect to the development of emavusertib could mean a significant change in the costs and timing associated with the development of emavusertib. For example, if the FDA or another regulatory authority requests additional or unanticipated data for our clinical trials or requires us to conduct clinical trials or other testing beyond those that we currently expect, or if we experience significant delays in enrollment in any of our clinical trials, we could be required to expend significant additional financial resources and time to complete clinical development of that drug candidate. We may never obtain regulatory approval for emavusertib. If we do obtain regulatory approval for our drug candidate, drug commercialization will take several years and the associated costs will be significant.

A further discussion of some of the risks and uncertainties associated with completing our research and development program on schedule, or at all, and some consequences of failing to do so, are set forth under Item 1A, “Risk Factors” of Part I of our Annual Report on Form 10-K for the year ended December 31, 2024, as supplemented by the risk factors discussed in Part II, Item 1A, “Risk Factors” of this Quarterly Report on Form 10-Q.

General and Administrative. General and administrative expense consists primarily of salaries and related expenses, including stock-based compensation expense for personnel in executive, finance, accounting, business development, legal, information technology, corporate communications and human resource functions. Other costs include facility costs not otherwise included in research and development expense, insurance, and professional fees for legal, patent and accounting services. Patent costs include certain patents covered under collaborations, a portion of which is reimbursed by collaborators and a portion of which is borne by us.

Critical Accounting Estimates

The preparation of our Condensed Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States requires that we make estimates and assumptions that affect the reported amounts and disclosure of certain assets and liabilities at our balance sheet date. We base our estimates on historical experience and on various other factors that we believe to be appropriate under the circumstances, the results of which form the basis for making judgments about the carrying value of certain liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

During the six months ended June 30, 2025, there were no material changes to our critical accounting estimates as reported in our Annual Report on Form 10-K for the year ended December 31, 2024, which was filed with the SEC on March 31, 2025.

Other income (expense) decreased by $1.1 million, or 148%, in the three months ended June 30, 2025 as compared the same period in 2024. The decrease was primarily attributable to a decrease in interest income and an increase in the expense related to the sale of future royalties.

Other income (expense) decreased by $2.1 million, or 162%, in the six months ended June 30, 2025 as compared to the same period in 2024. The decrease was primarily attributable to an increase in the expense related to the sale of future royalties and a decrease in interest income.

Liquidity and Capital Resources

We have financed our operations primarily through private and public placements of our equity securities, license fees, contingent cash payments and research and development funding from our corporate collaborators, and the monetization of certain royalty rights. See “Funding Requirements” below and Note 1, Nature of Business, in the accompanying Notes to the Condensed Consolidated Financial Statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q for a further discussion of our liquidity and the conditions and events that raise substantial doubt regarding our ability to continue as a going concern.

As of June 30, 2025, our principal sources of liquidity consisted of cash and cash equivalents of $10.1 million, excluding restricted cash, long-term of $0.5 million. Our cash and cash equivalents are highly liquid investments with a maturity of three months or less at date of purchase. We maintain cash balances with financial institutions in excess of insured limits.

Equity Offerings

In February 2024, we entered into an amended and restated sales agreement with Cantor Fitzgerald & Co. (“Cantor”) and JonesTrading Institutional Services LLC (“JonesTrading”) (the “2024 Sales Agreement”). Pursuant to the 2024 Sales Agreement, we can sell from time to time up to $100.0 million shares of the Company’s common stock through an “at-the-market offering” program under which Cantor and JonesTrading act as sales agents. The aggregate compensation payable to each of Cantor and JonesTrading is 3% of the gross proceeds from sales of the common stock sold by Cantor or JonesTrading, as applicable. We did not sell any shares of common stock under the 2024 Sales Agreement during the six months ended June 30, 2025. As of June 30, 2025, $98.8 million of shares of common stock remained available for sale under the 2024 Sales Agreement. On July 1, 2025, we notified Cantor and JonesTrading that we terminated the prospectus, dated April 12, 2024, related to the 2024 Sales Agreement. We will not make any sales of our common stock pursuant to the 2024 Sales Agreement unless and until a new prospectus relating to the shares of common stock to be issued and sold pursuant to the 2024 Sales Agreement is filed. The 2024 Sales Agreement remains in full force and effect, and we may issue and sell additional shares of

Table of Contents

our common stock thereunder in the future, provided we have an effective registration statement including a prospectus relating to such offers and sales at such time. However, as long as our public float is under $75.0 million, we are restricted from selling shares of our common stock under our shelf registration statement on Form S-3, including those sold under the 2024 Sales Agreement to an amount, in aggregate, that is no more than one-third of our public float during the 12 month period immediately prior to, and including, any such sale.

In October 2024, we entered into a securities purchase agreement with certain institutional investors, pursuant to which we issued and sold: (i) in a registered direct offering, 2,398,414 shares of our common stock and (ii) in a concurrent private placement, warrants to purchase up to an aggregate of 2,398,414 shares of our common stock, or the October 2024 Common Warrants, at an exercise price of $4.92 per share. We refer to the registered direct offering and concurrent private placement collectively as the October 2024 Offerings. The October 2024 Common Warrants were exercisable immediately upon closing on October 30, 2024 and will expire five years following the issuance date. The combined purchase price for one share of common stock and the associated October 2024 Common Warrant was $5.045. The net proceeds we received from the October 2024 Offerings were approximately $10.8 million, excluding the proceeds from any exercise of the October 2024 Common Warrants.

In March 2025, we entered into a securities purchase agreement with certain institutional investors, pursuant to which we issued and sold: (i) in a registered direct offering, 1,974,432 shares of our common stock and (ii) in a concurrent private placement, (a) in lieu of shares to certain investors, pre-funded warrants to purchase up to an aggregate of 2,184,009 shares of our common stock, or the March 2025 Pre-Funded Warrants, at an exercise price of $0.01 per share, and (b) warrants, or the March 2025 Common Warrants, to purchase up to an aggregate of 8,316,882 shares of our common stock, at an exercise price of $2.41 per share. We refer to the March 2025 Pre-Funded Warrants and March 2025 Common Warrants collectively as March 2025 Warrants and the registered direct offering and concurrent private placement collectively as the March 2025 Offerings. Each March 2025 Pre-Funded Warrant was exercisable immediately upon issuance and continuing through and including the date the March 2025 Pre-Funded Warrant is exercised in full. Each March 2025 Common Warrant was exercisable beginning on the effective date of stockholder approval of the issuance of the shares of common stock upon exercise of the March 2025 Common Warrants, which occurred on May 20, 2025, and will have a term of five years from the date of issuance. The combined purchase price for one share of our common stock and the associated March 2025 Common Warrant was $2.41. The combined purchase price for one March 2025 Pre-Funded Warrant and the associated March 2025 Common Warrant was $2.40. The net proceeds we received from the March 2025 Offerings were approximately $8.8 million, excluding the proceeds from any exercise of the March 2025 Warrants.

In July 2025, we entered into a securities purchase agreement with certain institutional investors, pursuant to which we issued and sold: (i) in a registered direct offering, 1,538,460 shares of our common stock and (ii) in a concurrent private placement, (a) in lieu of shares to certain investors, unregistered pre-funded warrants to purchase up to an aggregate of 1,538,461 shares of our common stock, or the July 2025 Pre-Funded Warrants, at an exercise price of $0.01 per share, and (b) unregistered warrants, or the July 2025 Common Warrants, to purchase up to an aggregate of 3,076,921 shares of our common stock, at an exercise price of $2.15 per share. We refer to the July 2025 Pre-Funded Warrants and the July 2025 Common Warrants collectively as Unregistered July 2025 Warrants. We refer to the registered direct offering and concurrent private placement collectively as the July 2025 Offerings. Each July 2025 Pre-Funded Warrant was exercisable immediately upon issuance and continuing through and including the date the July 2025 Pre-Funded Warrant is exercised in full. Each July 2025 Common Warrant was exercisable immediately upon issuance and has a term of five years from the date of issuance. The combined purchase price for one share of our common stock and the associated July 2025 Common Warrant was $2.275. The combined purchase price for one July 2025 Pre-Funded Warrant and the associated July 2025 Common Warrant was $2.265. The net proceeds we received from the July 2025 Offerings were approximately $6.0 million, excluding the proceeds from any exercise of the Unregistered July 2025 Warrants.

Royalty Interest Purchase Agreement

In March 2019, we and Curis Royalty entered into the royalty interest purchase agreement, or the Oberland Purchase Agreement, with the Purchasers. We sold to the Purchasers rights to a portion of certain royalty and royalty-related payments excluding a portion of non-U.S. royalties retained by Curis Royalty, referred to as the Purchased Receivables, owed by Genentech under our collaboration agreement with Genentech.

As upfront consideration for the purchase of the royalty rights, at closing the Purchasers paid to Curis Royalty $65.0 million less certain transaction expenses. For further discussion please refer to Note 6, Liability Related to the Sale of Future Royalties, in the accompanying Notes to the Condensed Consolidated Financial Statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q.

Table of Contents

The Oberland Purchase Agreement has default provisions, that if triggered, would require Curis Royalty to repurchase at a price, or the Put/Call Price, equal to 250% of the sum of the upfront purchase price and any portion of the milestone payments paid in a lump sum by the Purchasers, if any, minus certain payments previously received by the Purchasers with respect to the Purchased Receivables. As of June 30, 2025, the Put/Call Price was approximately $106.2 million.

Cash Flows from Operating Activities

Cash flows from operating activities consist of our net loss adjusted for various non-cash items and changes in operating assets and liabilities. Cash used in operating activities during the six months ended June 30, 2025 and 2024 was $15.3 million and $24.4 million, respectively. Net cash used in operations decreased by $9.1 million due to decreased operating expenses and timing of payments.

Cash Flows from Investing Activities

There was no cash provided by or used in investing activities during the six months ended June 30, 2025. Cash provided by investing activities during the six months ended June 30, 2024 was $11.6 million. Cash provided by investing activities during the prior period was primarily due to investment activity from purchases and sales or maturities of investments.

Cash Flows from Financing Activities

Cash provided by financing activities was $5.4 million and cash used in financing activities was $3.9 million during the six months ended June 30, 2025 and 2024, respectively. Cash provided by financing activities during the six months ended June 30, 2025 was primarily due to proceeds from the March 2025 Offerings, partially offset by payments related to the Oberland Purchase Agreement. Cash used in financing activities during the six months ended June 30, 2024 was due to payments related to the Oberland Purchase Agreement, partially offset by proceeds from common stock sold under the 2024 Sales Agreement.

Funding Requirements

We have incurred significant losses since our inception. As of June 30, 2025, we had an accumulated deficit of approximately $1.3 billion. We will require substantial funds in the immediate term to continue our research and development program and to fulfill our planned operating goals. Our planned operating and capital requirements currently include the support of our current and future research and development activities for emavusertib as well as development candidates we have and continue to license under our collaboration with Aurigene. We will require substantial additional capital in the immediate term to fund the further development of emavusertib and our general and administrative costs. Moreover, our agreements with collaborators impose significant potential financial obligations on us.

In July 2025, we completed the July 2025 Offerings for net proceeds of approximately $6.0 million. Based upon our current operating plan, we believe that our existing cash and cash equivalents of $10.1 million as of June 30, 2025, together with the proceeds from the July 2025 Offerings, should enable us to fund our existing operations into the first quarter of 2026. We have based this assessment on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect. Our current cash and cash equivalents are not expected to fund our operations beyond 12 months from the date of filing this Quarterly Report on Form 10-Q. See Note 1, Nature of Business, in the accompanying Notes to the Condensed Consolidated Financial Statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q for a further discussion of our liquidity and the conditions and events that raise substantial doubt regarding our ability to continue as a going concern. Our resources are focused on emavusertib. If we are unable to obtain sufficient funding, we will be forced to delay, reduce in scope or eliminate our research and development program for emavusertib, including related clinical trials and operating expenses, potentially delaying the time to market for, or preventing the marketing of, emavusertib, which would adversely affect our business prospects and our ability to continue operations, and would have a negative impact on our financial condition and our ability to pursue our business strategies. We have faced and expect to continue to face substantial difficulty in raising capital. Our ability to raise additional funds will depend on, among other factors, financial, economic and market conditions as well as maintaining our continued listing on Nasdaq, many of which are outside of our control, and we may be unable to raise financing when needed, or on terms favorable to us, or at all. In addition, we may seek to engage in one or more strategic alternatives, such as a strategic partnership with one or more parties, the licensing, sale or divestiture of some of our assets or proprietary technologies or the sale of our company, but there can be no assurance that we would be able to enter into such a transaction or transactions on a timely basis or on terms favorable to us, or at all. Our failure to raise capital through a financing or strategic alternative as and when needed would have a negative impact on our financial condition and our ability to pursue our business strategy. If we are unable to obtain sufficient capital, we would be unable to fund our operations and may be required to evaluate alternatives, which could include dissolving and liquidating our assets or seeking protection under the bankruptcy laws, and a determination to file for bankruptcy could occur at a time that is earlier than when we would otherwise exhaust our cash resources. If we decide to dissolve and liquidate our assets or to seek protection under the

Table of Contents

bankruptcy laws, it is unclear to what extent we would be able to pay our obligations, and, accordingly, it is further unclear whether and to what extent any resources would be available for distributions to stockholders.

Furthermore, there are a number of factors that may affect our future capital requirements and further accelerate our need for additional working capital, many of which are outside our control, including the following:

•unanticipated costs in our research and development program;

•the timing and cost of obtaining regulatory approvals for emavusertib and maintaining compliance with regulatory requirements;

•payments due to licensors, including Aurigene, for patent rights and technology used in our drug development programs;

•the costs of commercialization activities for emavusertib if it receives marketing approval, to the extent such costs are our responsibility, including the costs and timing of establishing drug sales, marketing, distribution and manufacturing capabilities;

•unplanned costs to prepare, file, prosecute, defend and enforce patent claims and other patent-related costs, including litigation costs and technology license fees; and

•our ability to continue as a going concern.

To become and remain profitable, we, either alone or with collaborators, must develop and eventually commercialize one or more drug candidates with significant market potential. This will require us to be successful in a range of challenging activities, including completing preclinical testing and clinical trials of our drug candidates, obtaining marketing approval for these drug candidates, manufacturing, marketing and selling those drugs for which we may obtain marketing approval and satisfying any post marketing requirements. We may never succeed in these activities and, even if we do, may never generate revenues that are significant or large enough to achieve profitability. While Erivedge is being commercialized by Genentech and Roche, emavusertib is currently only in early clinical testing.

For the foreseeable future, we will need to spend significant capital in an effort to develop and commercialize emavusertib and we expect to incur substantial operating losses. Our failure to become and remain profitable would, among other things, depress the market price of our common stock and could impair our ability to raise capital, expand our business, diversify our research and development program or continue our operations.

Not required.

Item 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls & Procedures

Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of June 30, 2025. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving

Table of Contents

their objectives and management necessarily applies its judgment in evaluating the cost benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of June 30, 2025, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control Over Financial Reporting

No change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the three months ended June 30, 2025 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1A. RISK FACTORS

We are subject to a number of risks that could materially and adversely affect our business, financial condition, and results of operations and future prospects, including those identified in Item 1A, “Risk Factors” of Part I of our Annual Report on Form 10-K for the year ended December 31, 2024, which was filed with the SEC on March 31, 2025, and the updated risk factors set forth below.

We are not in compliance with the requirements for continued listing on the Nasdaq Capital Market. If we fail to regain and maintain compliance with Nasdaq’s requirements, our common stock could be delisted from trading, which would decrease the liquidity of our common stock and our ability to raise additional capital.

Our common stock is currently listed on the Nasdaq Capital Market. We are required to meet specified requirements to maintain our listing on the Nasdaq Capital Market, including a minimum bid price of $1.00 per share for our common stock and standards relative to minimum stockholders’ equity, minimum market value of publicly held shares and various additional requirements. In the past we have, from time to time, received deficiency letters from Nasdaq as a consequence of our failure to satisfy such requirements. On February 21, 2025, we received a deficiency letter from Listing Qualifications Department of Nasdaq notifying us that the market value of our listed securities had closed for the last 30 consecutive business days below the minimum $35,000,000 requirement for continued listing on the Nasdaq Capital Market pursuant to Nasdaq Listing Rule 5550(b)(2), or Minimum MVLS Requirement. We have 180 calendar days, or until August 20, 2025, or Compliance Period, to regain compliance with the Minimum MVLS Requirement. In order to regain compliance, during the Compliance Period, the market value of our listed securities must close at $35,000,000 or more for a minimum of ten consecutive business days. If we do not regain compliance within the Compliance Period, we will receive written notification that our securities are subject to delisting from the Nasdaq Capital Market. At that time, we expect to appeal the delisting determination to a hearings panel pursuant to the procedures set forth in the applicable Nasdaq Listing Rules. The outcome of any such Nasdaq process is inherently uncertain. There can be no assurance that we can regain, or maintain in the future, compliance with the Nasdaq continued listing requirements.

If we fail to satisfy the Nasdaq Capital Market’s continued listing requirements and we are delisted from Nasdaq, we may transfer to and commence trading on the OTC Markets or another quotation medium. As a result, an investor would likely find it more difficult to trade or obtain accurate price quotations for our shares. Delisting would likely also reduce the visibility, liquidity, and value of our common stock, could have a material adverse effect on our access to capital markets and our ability to raise capital on terms acceptable to us, or at all, to provide stock-based incentives to attract and retain personnel, reduce institutional investor interest in our company, and may increase the volatility of our common stock. Delisting could also be considered a material adverse event or an event of default in certain of our third-party contracts or cause a loss of confidence of potential industry partners, lenders, and employees, which could further harm our business and our future prospects. In addition, our common stock could be deemed to be a “penny stock,” which could result in reduced levels of trading in our common stock, and we would also become subject to additional state securities regulations in connection with any sales of our securities. Some or all of these material adverse consequences may contribute to a further decline in our stock price.

Changes in and uncertainty surrounding U.S. trade policy could have a material adverse impact on our business, financial condition and results of operations.

We rely on third party contract manufacturing organizations, or CMOs, to produce our product candidate. One of our CMOs has a Chinese subcontractor that produces regulatory starting materials. Another CMO operates in Canada and produces our drug product. This past spring, the Trump administration initiated a series of tariff-related actions against U.S. trading partners. On April 2, 2025, the President issued an executive \order announcing a “baseline” reciprocal tariff of 10% on all U.S. trading partners effective April 5, 2025, and higher individualized reciprocal tariffs on 57 countries (with certain product exemptions for pharmaceutical-related products, among others). Previously, the administration had imposed a 25% tariff on Canada and Mexico for goods not covered by the United States-Mexico-Canada Agreement, or USMCA, and tariffs equaling

Table of Contents

20% on China. In response, several countries threatened retaliatory measures, including Canada and China, which then imposed retaliatory tariffs. Prior to when the country-specific reciprocal tariffs were scheduled to take effect, the administration delayed the effective date of such tariffs for all countries except China. Later, the U.S. and China reached a framework agreement that resulted in the suspension of the higher reciprocal tariffs on China until August 10, 2025. Three other countries, the United Kingdom, Vietnam and Indonesia, have also reached deals with the US that include reduced tariff rates and other measures. The administration has not indicated the effective date for these deals. Recently, the administration announced an extension of the deadline for the effective date of the country-specific tariffs for all remaining countries until August 1, 2025.

Currently, the 10% baseline reciprocal tariff announced in April remains in effect, in addition to the other tariffs on China (a minimum of an additional 20% as of July 15, 2025) and Canada and Mexico (25% as of July 15, 2025 for goods that are not covered by the USMCA). Sustained uncertainty about, or the further escalation of, trade and political tensions between the United States and China could result in a disadvantageous research and manufacturing environment in China, particularly for U.S. based companies, including retaliatory restrictions that hinder or potentially inhibit our ability to rely on contract development and manufacturing organizations and other service providers that operate in China.

Separately, on April 16, 2025, the U.S. Department of Commerce announced an investigation under Section 232 of the Trade Expansion Act of 1962 into imports of pharmaceuticals and pharmaceutical ingredients, including finished drug products, medical countermeasures, critical inputs such as active pharmaceutical ingredients, and key starting materials, and derivative products of those items. The investigation will examine the impact of these imports on U.S. national security culminating in a decision by the President whether to take action to remedy any identified threats, including by imposing additional tariffs. The statute provides that the Commerce Department report must be completed within 270 days of initiation of the investigation and that the President must decide whether to act within 90 days of receiving the report.

As a result of changes in tariffs that have been announced and/or implemented, and the underlying uncertainty currently surrounding international trade, we could experience a negative impact to our costs of materials and production processes, and supply chain disruptions and delays as a result of any new tariff policies or trade restrictions. If we are unable to obtain necessary raw materials or product components in sufficient quantity and in a timely manner due to disruptions in the global supply chain caused by macroeconomic events and conditions, the development, testing and clinical trials of our product candidate may be delayed or infeasible, and regulatory approval or commercial launch of any resulting product may be delayed or not obtained, which could significantly harm our business. We cannot yet predict the effect of the recently imposed U.S. tariffs on imports, or the extent to which other countries will impose quotas, duties, tariffs, taxes or other similar restrictions upon imports or exports in the future, nor can we predict future trade policy or the terms of any renegotiated trade agreements and their impact on our business.

Disruptions at the FDA and other government agencies from funding cuts, personnel losses, regulatory reform, government shutdowns and other developments could hinder our ability to obtain guidance from the FDA regarding our clinical development program and develop and secure approval of our product candidates in a timely manner, which would negatively impact our business.

The U.S. Food and Drug Administration, or FDA, and comparable regulatory agencies in foreign jurisdictions, such as the European Medicines Agency, or EMA, and the EMA’s Committee for Medicinal Products for Human Use, play a critical role in the development of our product candidates by providing guidance on our clinical development programs and reviewing and approving our regulatory submissions, including investigational new drug applications, or INDs, requests for special designations and marketing applications. If these oversight and review activities are disrupted or delayed or previous alignment with the agencies is changed, then correspondingly our ability to develop and secure timely approval of our product candidates could be impacted in a negative manner.

For example, the loss of FDA leadership and personnel could lead to disruptions and delays in FDA guidance, review and approval of our product candidates. Pursuant to President Trump's E.O. 14210, “Implementing the President’s ‘Department of Government Efficiency’ Workforce Optimization Initiative,” the Secretary of the Department of Health and Human Services, or HHS, announced on March 27, 2025, a reorganization and Reduction in Force, or RIF, across HHS of approximately 20,000 employees (82,000 to 62,000), with FDA’s workforce of approximately 20,000 to decrease by 3,500 full-time employees. Subsequently, the FDA indicated that roughly a quarter of those employees who received RIF notices had been reinstated. On July 14, 2025, following litigation reaching the US Supreme Court, the administration began to carry out these layoffs across HHS, including the FDA. There are also ongoing deliberations within the administration and Congress over potentially substantial proposed cuts to the overall budget for HHS and funding of the FDA for the 2026 federal fiscal year.

Further, while the FDA’s review of marketing applications and other activities for new drugs and biologics is largely funded through the user fee program established under the Prescription Drug User Fee Act, or PDUFA, it remains unclear how the administration’s RIF and budget cuts will impact this program and the ability of the FDA to provide guidance and review

Table of Contents

our product candidates in a timely manner. For example, while the FDA RIF did not reportedly specifically target FDA reviewers, many operations, administrative and policy staff that help support such reviews were affected and those losses could lead to delays in PDUFA reviews and related activities. As of July 15, 2025, there has been at least one report in which the FDA failed to meet a PDUFA goal date for approval of an NDA due to heavy workload and limited resources. In addition, while currently unclear, there is a risk that the RIF and budget cutbacks could threaten the integrity of the PDUFA program itself. That is because, for the FDA to obligate user fees collected under PDUFA in the first place, a certain amount of non-user fee appropriations must be spent on the process for the review of applications plus certain other costs during the same fiscal year.

There is also substantial uncertainty as to how regulatory reform measures being implemented by the Trump Administration across the government will impact the FDA and other federal agencies with jurisdiction over our activities. For example, since taking office, the President has issued a number of executive orders that could have a significant impact on the manner in which the FDA conducts its operations and engages in regulatory and oversight activities. These include E.O. 14192, “Unleashing Prosperity Through Deregulation,” January 31, 2025; E.O. 14212, “Establishing the President’s Make America Healthy Again Commission,” February 13, 2025; and E.O. 14219, Ensuring Lawful Governance and Implementing the President’s ‘Department of Government Efficiency” Deregulatory Initiative,” February 21, 2025. If these or other orders or executive actions impose constraints on the FDA’s ability to engage in oversight and implementation activities in the normal course, our business may be negatively impacted.

Similarly, actions by the U.S. government have significantly disrupted the operations of U.S. government agencies such as the National Institutes of Health, National Science Foundation, Centers for Disease Control and Prevention, and FDA, which have traditionally provided funding for basic research, research and development, and clinical testing. These U.S. government actions have included, among other things, suspending, terminating and withholding of disbursements of funds owed under ongoing contracts, grants, and other financial assistance agreements; declining to continue multi-year research projects for additional annual budget periods; canceling or delaying solicitations for new contract, grant and other financial assistance awards; canceling or delaying proposal evaluation processes and issuance of such new awards; substantially reducing federal agency staff responsible for managing contract and financial assistance programs; eliminating agency information and resources for facilitating research activity; delaying or terminating federal agency procedures for authorizing international transactions; initiating aggressive enforcement actions that may disrupt the operations of major research universities that are significant contributors to life sciences research in the U.S., and threatening access to federal agency contracts and other funding awards based on companies’ otherwise lawful corporate policies and choice of counsel. These U.S. government actions could, directly or indirectly, significantly disrupt, delay, prevent, or increase the costs of our research and product commercialization programs, including our ability to develop new product candidates, conduct clinical trials, implement research collaborations with other companies or institutions, and obtain approvals to market and sell new products.

In addition, government funding of the Securities and Exchange Commission, or SEC, and other government agencies on which our operations may rely, including those that fund research and development activities, is subject to the political process, which is inherently fluid and unpredictable. For example, over the last several years, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA, SEC and other government employees and stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions and could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

At the same time, disruptions at the FDA and other government agencies may result from public health events similar to the COVID-19 pandemic. For example, during the pandemic, a number of companies announced receipt of complete response letters due to the FDA’s inability to complete required inspections for their applications. In the event of a similar public health emergency in the future, the FDA may not be able to continue its current pace and review timelines could be extended. Regulatory authorities outside the United States facing similar circumstances may adopt similar restrictions or other policy measures in response to a similar public health emergency and may also experience delays in their regulatory activities.

Accordingly, if any of the foregoing developments and others impact the ability of the FDA to provide us with guidance regarding our clinical development programs or delay the agency’s review and processing of our regulatory submissions, including INDs and new drug applications/biologics license applications, our business would be negatively impacted. Further, any future government shutdown could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

THIS EMPLOYMENT AGREEMENT (the “Agreement”), is entered into by and between Curis, Inc., a Delaware corporation (the “Company”), and Ahmed Hamdy, M.D. (the “Employee”).

WHEREAS the Company desires to employ the Employee, and the Employee desires to be employed by the Company on the terms set forth in this Agreement. In consideration of the mutual covenants and promises contained herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1. Term of Employment. The Company hereby agrees to employ the Employee, and the Employee hereby accepts employment with the Company, upon the terms set forth in this Agreement, for the period commencing on May 1, 2025 (the “Commencement Date”) and continuing until terminated in accordance with the provisions of Section 4 (the “Employment Period”). During the Employment Period, the Employee shall be an at-will employee of the Company and the Employee’s employment and the Employment Period shall be freely terminable by either party, for any reason, at any time, with or without cause or notice, subject to the provisions set forth in Section 4 below.

2. Position.

(a) The Employee shall serve as Chief Medical Officer. The Employee shall have such duties and authority consistent with his position as may be assigned from time to time by the President and Chief Executive Officer of the Company. The Employee shall report to, and be subject to the supervision of, the President and Chief Executive Officer. The Employee agrees to devote his entire business time to the business and interests of the Company during the Employment Period provided, however, that the Employee may serve on up to two Boards of Directors (whether for-profit or not-for-profit) as long as such activities do not, alone or in the aggregate, materially interfere with the performance of the Employee’s duties under this Agreement, as determined in good faith by the President and Chief Executive Officer of the Company and do not otherwise violate any restrictive covenants applicable to the Employee or any other written agreement between the Company and the Employee. Employee shall be expected to divide his work time between California, travel to conferences and clinical sites, and travel to Company headquarters in Lexington, Massachusetts.

(b) The Employee agrees to abide by the rules, regulations, instructions, personnel practices and policies of the Company and any changes therein which may be adopted from time to time by the Company.

3. Compensation and Benefits.

3.1 Salary. During the Employment Period, the Company shall pay the Employee, in periodic installments in accordance with the Company’s customary payroll practices, a base salary of $19,996.15 per bi-weekly pay period (based upon 26 bi-weekly pay periods per annum,

equal to $519,900 per annum. Such salary shall be subject to annual review by the Board of Directors of the Company (the “Board”) and/or the Compensation Committee of the Board (the “Compensation Committee”).

3.2 Equity Compensation. Subject to approval by the Compensation Committee of the Board of Directors, and as a material inducement to the Employee entering into employment with the Company, on or about the Commencement Date, the Employee shall be granted an option to purchase 200,000 shares of Common Stock, $0.01 par value (“Common Stock”) of the Company, such option to (a) be exercisable at a price per share equal to the closing price of the Company’s Common Stock on the NASDAQ Stock Market on date of grant, (b) vest and become exercisable, subject to the Employee’s continued service, at a rate of 25% of the total shares underlying the option on the first anniversary of the date of grant and as to an additional 6.25% of the total shares underlying the option at the end of each successive three-month period thereafter, (c) be awarded outside of the Company’s stock incentive plans as an “inducement grant” within the meaning of Nasdaq Listing Rule 5635(c)(4), (d) be a nonqualified stock option and (e) be subject to the terms and conditions of a nonqualified stock option agreement by and between the Employee and the Company. The Board or the Compensation Committee may award stock options or other equity compensation to the Employee from time to time in their sole discretion. The Employee may be eligible for an annual performance equity-based award in connection with the Company’s annual performance equity award cycle beginning in calendar year 2026.

3.3 Bonus; Cash Incentives.

(a) The Compensation Committee has the authority to award discretionary annual cash bonuses to the executive officers of the Company, including the Employee. Any bonus awarded shall be based on the achievement of specific objectives and other factors established by the Board or the Compensation Committee. Such bonus (if any) will be paid in the form of cash or capital stock, as determined by the Compensation Committee. Upon the determination of the Compensation Committee, acting in its sole discretion, the Employee may be entitled to receive an annual bonus. The target bonus amount for which the Employee shall be eligible is forty percent (40%) of his base salary.

(b) Any bonus or cash incentive awarded to Employee will be paid on or before March 15 of the calendar year immediately following the year for which the bonus or cash incentive was earned.

3.4 Fringe Benefits. The Employee shall be entitled to participate in all medical and other benefit programs that the Company establishes and makes available to its employees, if any, to the extent that the Employee’s position, tenure, salary, age, health, and other qualifications make him eligible to participate. This comprehensive program currently covers medical and dental benefits, life and disability insurances, and a Section 125 Plan. The Employee will also be eligible to participate in the Company’s 401(k) Plan. The Employee shall be entitled to three weeks’ paid vacation per year subject to the Company’s policies for accrual and use.

3.5 Reimbursement of Expenses. The Company shall reimburse the Employee for all reasonable travel, entertainment and other expenses incurred or paid by the Employee in connection with, or related to, the performance of his duties, responsibilities or services under this Agreement, upon presentation by the Employee of documentation, expense statements, receipts, vouchers and/or such other supporting information as the Company may request, provided, however, that the maximum amount available for such travel, entertainment and other expenses may be fixed in advance by the Company.

3.6 Tax Services Fees.

(a) The Company shall reimburse the Employee for reasonable documented tax and professional services expenses, up to a maximum of seven thousand five hundred ($7,500) dollars per year, incurred by the Employee in connection with the preparation of the Employee’s personal income tax returns and estate planning (the “Professional Services Fees”).

(b) The Company shall pay the Employee a gross up payment equal to the sum of any Federal and State Income Taxes and Social Security and Medicare Employment Taxes (collectively, the “Taxes”) payable with respect to the Professional Services Fees, plus such additional Taxes as may be imposed on the Employee attributable to the receipt of such gross up payment. Any such payment for Taxes shall be made no later than 60 days following the end of the year in which the Employee remits the Taxes.

3.7 Withholding. All salary, bonus, severance, and other compensation payable to the Employee shall be subject to applicable withholdings.

4. Termination of Employment.

(a) The Company has the right to terminate the Employee’s employment under this Agreement, by notice to the Employee in writing (i) for Cause (as defined below), (ii) without Cause for any or no reason, or (iii) due to the Disability (as defined below) of the Employee. Any such termination shall be effective upon the date of such notice to the Employee, or such other date as may be specified in such notice, in the case of termination for Cause or termination due to Disability, and upon 30 days’ prior written notice to the Employee in the case of termination without Cause for any or no reason.

(b) Employee’s employment under this Agreement shall terminate immediately upon the Employee’s death.

(c) The Employee shall have the right to terminate his employment under this Agreement (i) for any reason or no reason upon 30 days’ prior written notice to the Company or (ii) for Good Reason (as defined below).

(d) As used in this Agreement, the terms below shall have the following meanings:

(i) “Cause” means (a) a good faith finding by the Company of the Employee’s failure or refusal to substantially perform his duties or the Employee’s continued neglect to perform such duties to the full extent of his abilities for reasons other than death, physical or mental incapacity, (b) a good faith finding by the Company of the Employee’s failure to perform his duties as assigned to him by the Board, or the President and Chief Executive Officer of the Company, (c) a good faith finding by the Company of dishonesty, gross negligence, or misconduct, (d) conviction or the entry of a pleading of guilty or nolo contendere to any crime or felony, or (e) any breach or threatened breach of any confidentiality, non-solicitation, or inventions agreement with the Company. For purposes of determining “Cause” during the 12 months following the consummation of a Change in Control Event, “Cause” shall instead be determined as provided in Section 10(c)(1)(C) of the Company’s Fifth Amended and Restated 2010 Stock Incentive Plan, as amended or replaced from time to time, provided that this Agreement’s definition shall apply if no such definition appears in the then current equity plan.

(ii) “Good Reason” shall mean (a) any material diminution in the Employee’s authority, duties or responsibilities (b) any material reduction in his annual base salary; (c) any material breach by the Company of this Agreement; or (d) any requirement by the Company or of any person in control of the Company that the location at which the Employee performs his principal duties for the Company be changed to a new location that is more than 40 miles from the current principal location of the Company or that Employee no longer be allowed to divide his work time between North Carolina and the current principal location of the Company, provided that (i) the Employee provides the Company with notice of the condition described above within 90 days after the initial existence of the condition; (ii) such condition is not remedied by the Company within 30 days after receiving the notice and (iii) the Employee separates from service with the Company no later than 30 days following the last day of the cure period in clause (ii).

(iii) “Change in Control Event” shall mean:

(A) The acquisition by an individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act) (a “Person”) of beneficial ownership of any capital stock of the Company if, after such acquisition, such Person beneficially owns (within the meaning of Rule 13d-3 promulgated under the Exchange Act) 50% or more of either (x) the then-outstanding shares of common stock of the Company (the “Outstanding Company Common Stock”) or (y) the combined voting power of the then-outstanding securities of the Company entitled to vote generally in the election of directors (the “Outstanding Company Voting Securities”); provided, however, that for purposes of this subsection (i), the following acquisitions shall not constitute a Change in

Control Event: (1) any acquisition directly from the Company (excluding an acquisition pursuant to the exercise, conversion or exchange of any security exercisable for, convertible into or exchangeable for common stock or voting securities of the Company, unless the Person exercising, converting or exchanging such security acquired such security directly from the Company or an underwriter or agent of the Company), (2) any acquisition by any employee benefit plan (or related trust) sponsored or maintained by the Company or any corporation controlled by the Company, or (3) any acquisition by any entity pursuant to a Business Combination (as defined below) which complies with clauses (x) and (y) of subsection (C) of this definition; or

(B) Such time as the Continuing Directors (as defined below) do not constitute a majority of the Board (or, if applicable, the Board of Directors of a successor to the Company), where the term “Continuing Director” means at any date a member of the Board (x) who was a member of the Board on the date of the initial adoption of this Agreement by the Board or (y) who was nominated or elected subsequent to such date by at least a majority of the directors who were Continuing Directors at the time of such nomination or election or whose election to the Board was recommended or endorsed by at least a majority of the directors who were Continuing Directors at the time of such nomination or election; or

(C) The consummation of a merger, consolidation, reorganization, recapitalization or share exchange involving the Company or a sale or other disposition of all or substantially all of the assets of the Company (a “Business Combination”), unless, immediately following such Business Combination, each of the following two conditions is satisfied: (x) all or substantially all of the individuals and entities who were the beneficial owners of the Outstanding Company Common Stock and Outstanding Company Voting Securities immediately prior to such Business Combination beneficially own, directly or indirectly, more than 50% of the then-outstanding shares of common stock or other common equity and the combined voting power of the then-outstanding securities entitled to vote generally in the election of directors, respectively, of the resulting or acquiring corporation or other form of entity in such Business Combination (which shall include, without limitation, a corporation which as a result of such transaction owns the Company or substantially all of the Company’s assets either directly or through one or more subsidiaries) (such resulting or acquiring corporation or entity is referred to herein as the “Acquiring Corporation”) in substantially the same proportions as their ownership of the Outstanding Company Common Stock and Outstanding Company Voting Securities, respectively, immediately prior to such Business Combination and (y) no Person (excluding the Acquiring

Corporation or any employee benefit plan (or related trust) maintained or sponsored by the Company or by the Acquiring Corporation) beneficially owns, directly or indirectly, 50% or more of the then-outstanding shares of common stock of the Acquiring Corporation, or of the combined voting power of the then-outstanding securities of such corporation entitled to vote generally in the election of directors (except to the extent that such ownership existed prior to the Business Combination).

Notwithstanding the foregoing, where required to avoid extra taxation under Section 409A, a Change in Control must also satisfy the requirements of Treas. Reg. Section 1.409A-3(a)(5).

(iv) “Disability” shall be deemed to have occurred when the Employee shall have been unable to perform his duties by reason of illness or incapacity for a period of 120 consecutive days in any period of 52 consecutive weeks, as determined in good faith by the Board in accordance with applicable law.

5. Compensation upon Termination.

(a) In the event the Employee’s employment is terminated by the Company for Cause, by the Employee without Good Reason or due to the death or Disability of the Employee, the Company shall pay to the Employee (i) any earned but unpaid base salary and, to the extent consistent with general Company policy or applicable law, accrued but unused vacation/paid time off through and including the date the Employee’s employment with the Company ends, to be paid in accordance with the Company’s regular payroll practices and with applicable law but no later than the next regularly scheduled pay period, (ii) unreimbursed business expenses in accordance with the Company’s policies for which expenses the Employee has provided appropriate documentation, to be paid in accordance with Section 14.2, and (iii) any amounts or benefits to which the Employee is then entitled under the terms of the benefit plans (other than severance) then sponsored by the Company in accordance with their terms (and not accelerated to the extent acceleration does not satisfy Section 409A as defined below)). Medical/dental insurance as an Employee of the Company will cease upon the date employment ends (or such later date as the insurance policies provide), and the Employee will be eligible for continuation of such coverage pursuant to COBRA at his expense except as provided below (or prohibited under COBRA).

(b) In the event the Employee’s employment terminates as a result of a termination by the Employee for Good Reason, or a termination by the Company without Cause (except for a termination covered by 5(c)), in addition to the compensation and benefits described in Section 5(a), (i) the Employee shall receive payments equal to nine months of the Employee’s then base salary ratably over a period of nine months in accordance with the Company’s then current payroll policies and practices, and a payment equal in amount to his target bonus for the year of termination, pro-rated to reflect days elapsed from the beginning of the bonus year to the date of termination over

365 and paid on or around the date of the first installment of the salary-based severance, and (ii) the Company will pay any difference between the COBRA premium and the amount the Employee would otherwise be responsible for with respect to the medical and dental coverage elected for a period of nine months from the date such termination or as long as the Employee is eligible for and elects to be covered by COBRA, whichever period is shorter. At the end of this period, the Employee is eligible to continue coverage for the balance of the statutory period under COBRA, provided that the Employee pays the COBRA premium. Notwithstanding the foregoing, the Company may end the payment of premiums earlier (but not the Employee’s eligibility for COBRA) if it reasonably determines that applicable laws or regulations are reasonably likely to cause the payment of these premiums to trigger taxes or penalties on the Company or other participants or, to the extent the Employee would be taxed on more than the amount of the premiums, to the Employee.

(c) In the event that, within 12 months following a Change in Control Event, the Employee’s employment terminates as a result of a termination by the Employee for Good Reason, or a termination by the Company or its successor without Cause, in addition to the compensation and benefits described in Section 5(a), the Employee shall receive (i) one times the sum of (x) the Employee’s then base salary (or if the base salary was reduced within 12 months following a Change in Control Event from the level in effect immediately before the consummation of that event, the level before such reduction) and (y) an amount equal to the full target bonus for the year of termination, such sum to paid ratably over a period of 12 months in accordance with the Company’s then current payroll policies and practices and (ii) an amount equal to a portion of the same year’s target bonus, pro-rated to reflect days elapsed from the beginning of the bonus year to the date of termination over 365, with the payment in clause (ii) to be made on or around the date of the first installment of the payments under clause (i). If severance is due under the proceeding sentence, the Company will also pay any difference between the COBRA premium and the amount the Employee would otherwise be responsible for with respect to the medical and dental coverage elected for a period of 12 months from the date of such termination or as long as the Employee is eligible for and elects to be covered by COBRA, whichever period is shorter. At the end of this period, the Employee is eligible to continue coverage for the balance of the statutory period under COBRA, provided that the Employee pays the COBRA premium. Notwithstanding the foregoing, the Company may end the payment of premiums earlier (but not the Employee’s eligibility for COBRA) if it reasonably determines that applicable laws or regulations are reasonably likely to cause the payment of these premiums to trigger taxes or penalties on the Company or other participants or, to the extent the Employee would be taxed on more than the amount of the premiums, to the Employee. The benefits provided under this Section 5(c) shall be in lieu of any benefits to which the Employee would have otherwise been entitled pursuant to Section 5(b) of this Agreement.

(d) The receipt of any severance benefits provided for under this Agreement or otherwise shall be dependent upon the Employee’s delivery to the Company of an

effective general release of claims in a form provided by the Company. Such release must be delivered and become irrevocable within 60 days (or such shorter period as the Company may specify at the time) of the date of the Employee’s termination of employment. Payment of the benefits shall be made or commence no later than the first payroll period following the date on which the release becomes irrevocable. Notwithstanding the foregoing, if the 60th day following the termination of employment occurs in the calendar year following the year of the Employee’s termination of employment then the severance payments shall not be made or commence prior to January 1 of the year following such termination of employment, and in any event, payment of benefits under this subparagraph shall be subject to the provisions of Section 14 to the extent applicable.

(e) The benefits provided for the Employee under this Agreement shall be the sole payments and benefits for which the Employee shall be eligible at the conclusion of his employment with the Company for any reason (other than as provided under the terms of any equity compensation plans or awards) and shall supersede any and all prior agreements or arrangements for post-termination benefits or severance.

Any such communication shall be sent either (a) by registered or certified mail, return receipt requested, postage prepaid, or (b) via a reputable nationwide overnight courier service, in each case to the address set forth below.

8. Amendment. This Agreement may be amended or modified only by a written instrument executed by both the Company and the Employee.

9. Governing Law. Except as set forth in Section 13.14, the Agreement shall be governed by and construed in accordance with the laws of the Commonwealth of Massachusetts without giving effect to principles of conflicts of laws. Except as set forth in Section 13.16, any action, suit, or other legal proceeding which is commenced to resolve any matter arising under or relating to any provision of the Agreement shall be commenced only in a court of the Commonwealth of Massachusetts (or, if appropriate, a federal court located within Massachusetts), and the Company and the Employee each consents to the jurisdiction of such a court.

10. Successors and Assigns. The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of the Company expressly to assume and agree to perform the Agreement to the same extent that the Company would be required to perform it if no such succession had taken place. As used in the Agreement, “Company” shall mean the Company as defined above and any successor to its business or assets as aforesaid which assumes and agrees to perform the Agreement, by operation of law or otherwise.

11. Miscellaneous.

11.1 No delay or omission by the Company in exercising any right under this Agreement shall operate as a waiver of that or any other right. A waiver or consent given by the Company on any one occasion shall be effective only in that instance and shall not be construed as a bar or waiver of any right on any other occasion.

11.2 The captions of the sections of this Agreement are for convenience of reference only and in no way define, limit or affect the scope or substance of any section of this Agreement.

11.3 In case any provision of this Agreement shall be invalid, illegal, or otherwise unenforceable, the validity, legality and enforceability of the remaining provisions shall in no way be affected or impaired thereby.

12. No Duty to Seek Employment. The Employee and the Company acknowledge and agree that nothing contained in this Agreement shall be construed as requiring the Employee to seek or accept alternative or replacement employment in the event of his termination of employment by the Company for any reason, and no payment or benefit payable hereunder shall be conditioned on the Employee’s seeking or accepting such alternative or replacement employment.

13. Indemnification. Until the later of (1) six years after the date that the Employee shall have ceased to serve as an employee or officer of the Company or, at the request of the Company, as a director, officer, partner, trustee, member, employee or agent of another corporation, partnership, joint venture, trust, limited liability company or other enterprise or (2) the final termination of all Proceedings (as defined below) pending on the date set forth in clause (1) in respect of which the Employee is granted rights of indemnification or advancement of

Expenses (as defined below) hereunder and of any proceeding commenced by the Employee pursuant to Section 13.8 of this Agreement relating thereto, the Company shall provide indemnification to the Employee as follows:

13.1 Indemnification in Third-Party Proceedings. The Company shall indemnify the Employee in accordance with the provisions of this Section 13.1 if the Employee was or is a party to or threatened to be made a party to or otherwise involved in any Proceeding (other than a Proceeding by or in the right of the Company to procure a judgment in its favor) by reason of the Employee’s Corporate Status or by reason of any action alleged to have been taken or omitted in connection therewith, against all Expenses, judgments, fines, penalties and amounts paid in settlement actually and reasonably incurred by or on behalf of the Employee in connection with such Proceeding, if the Employee acted in good faith and in a manner which the Employee reasonably believed to be in, or not opposed to, the best interests of the Company and, with respect to any criminal Proceeding, had no reasonable cause to believe that his conduct was unlawful. The termination of any Proceeding by judgment, order, settlement, conviction or upon a plea of guilty or nolo contendere or its equivalent, shall not, of itself, create a presumption that the Employee did not act in good faith and in a manner which the Employee reasonably believed to be in, or not opposed to, the best interests of the Company, and, with respect to any criminal Proceeding, had reasonable cause to believe that his conduct was unlawful.

13.2 Indemnification in Proceedings by or in the Right of the Company. The Company shall indemnify the Employee in accordance with the provisions of this Section 13.2 if the Employee was or is a party to or threatened to be made a party to or otherwise involved in any Proceeding by or in the right of the Company to procure a judgment in its favor by reason of the Employee’s Corporate Status (as defined below) or by reason of any action alleged to have been taken or omitted in connection therewith, against all Expenses and, to the extent permitted by law, amounts paid in settlement actually and reasonably incurred by or on behalf of the Employee in connection with such Proceeding, if the Employee acted in good faith and in a manner which the Employee reasonably believed to be in, or not opposed to, the best interests of the Company, except that no indemnification shall be made under this Section 13.2 in respect of any claim, issue, or matter as to which the Employee shall have been adjudged to be liable to the Company, unless, and only to the extent, that the Court of Chancery of Delaware or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of such liability but in view of all the circumstances of the case, the Employee is fairly and reasonably entitled to indemnity for such Expenses as the Court of Chancery or such other court shall deem proper.

13.3 Exceptions to Right of Indemnification. Notwithstanding anything to the contrary in this Agreement, except as set forth in Section 13.8, the Company shall not indemnify the Employee in connection with a Proceeding (or part thereof) initiated by the Employee unless the initiation thereof was approved by the Board. Notwithstanding anything to the contrary in this Agreement, the Company shall not indemnify the Employee to the extent the Employee is reimbursed from the proceeds of insurance, and in the event the Company makes any indemnification payments to the Employee and the Employee is subsequently reimbursed from the proceeds of insurance, the

Employee shall promptly refund such indemnification payments to the Company to the extent of such insurance reimbursement.

13.4 Indemnification of Expenses of Successful Party. Notwithstanding any other provision of this Agreement, to the extent that the Employee has been successful, on the merits or otherwise, in defense of any Proceeding or in defense of any claim, issue or matter therein, the Employee shall be indemnified against all Expenses incurred by or on behalf of Employee in connection therewith. Without limiting the foregoing, if any Proceeding or any claim, issue or matter therein is disposed of, on the merits or otherwise (including a disposition without prejudice), without (i) the disposition being adverse to the Employee, (ii) an adjudication that the Employee was liable to the Company, (iii) a plea of guilty or nolo contendere by the Employee, (iv) an adjudication that Employee did not act in good faith and in a manner the Employee reasonably believed to be in or not opposed to the best interests of the Company, and (v) with respect to any criminal proceeding, an adjudication that the Employee had reasonable cause to believe his conduct was unlawful, the Employee shall be considered for the purposes hereof to have been wholly successful with respect thereto.

13.5 Notification and Defense of Claim. As a condition precedent to the Employee’s right to be indemnified, the Employee must notify the Company in writing as soon as practicable of any Proceeding for which indemnity will or could be sought. With respect to any Proceeding of which the Company is so notified, the Company will be entitled to participate therein at its own expense and/or to assume the defense thereof at its own expense, with legal counsel reasonably acceptable to the Employee. After notice from the Company to the Employee of its election so to assume such defense, the Company shall not be liable to the Employee for any legal or other expenses subsequently incurred by the Employee in connection with such Proceeding, other than as provided below in this Section 13.5. The Employee shall have the right to employ his own counsel in connection with such Proceeding, but the fees and expenses of such counsel incurred after notice from the Company of its assumption of the defense thereof shall be at the expense of the Employee unless (i) the employment of counsel by the Employee has been authorized by the Company, (ii) counsel to the Employee shall have reasonably concluded that there may be a conflict of interest or position on any significant issue between the Company and the Employee in the conduct of the defense of such Proceeding or (iii) the Company shall not in fact have employed counsel to assume the defense of such Proceeding, in each of which cases the fees and expenses of counsel for the Employee shall be at the expense of the Company, except as otherwise expressly provided by this Agreement. The Company shall not be entitled, without the consent of the Employee, to assume the defense of any claim brought by or in the right of the Company or as to which counsel for the Employee shall have reasonably made the conclusion provided for in clause (ii) above. The Company shall not be required to indemnify the Employee under this Agreement for any amounts paid in settlement of any Proceeding effected without its written consent. The Company shall not settle any Proceeding in any manner which would impose any penalty or limitation on the Employee without the Employee’s written consent. Neither the Company nor the Employee will unreasonably withhold or delay their consent to any proposed settlement.

13.6 Advancement of Expenses. Subject to the provisions of Section 13.7 of this Agreement, in the event that the Company does not assume the defense pursuant to Section 13.5 of this Agreement of any Proceeding of which the Company receives notice under this Agreement, any Expenses incurred by or on behalf of the Employee in defending such Proceeding shall be paid by the Company in advance of the final disposition of such Proceeding; provided, however, that the payment of such Expenses incurred by or on behalf of the Employee in advance of the final disposition of such Proceeding shall be made only upon receipt of an undertaking by or on behalf of the Employee to repay all amounts so advanced in the event that it shall ultimately be determined that the Employee is not entitled to be indemnified by the Company as authorized in this Agreement. Such undertaking shall be accepted without reference to the financial ability of the Employee to make repayment.

13.7 Procedure for Indemnification. In order to obtain indemnification or advancement of Expenses pursuant to Sections 13.1, 13.2, 13.4 or 13.6 of this Agreement, the Employee shall submit to the Company a written request. Any such indemnification or advancement of Expenses shall be made promptly, and in any event within 30 days after receipt by the Company of the written request of the Employee, unless with respect to requests under Sections 13.1, 13.2 or 13.6 the Company determines within such 30-day period that the Employee did not meet the applicable standard of conduct set forth in Section 13.1 or 13.2, as the case may be. Such determination, and any determination that advanced Expenses must be repaid to the Company, shall be made in each instance (i) by a majority vote of the directors of the Company consisting of persons who are not at that time parties to the Proceeding (“disinterested directors”), whether or not a quorum, (ii) by a committee of disinterested directors designated by a majority vote of disinterested directors, whether or not a quorum, (iii) if there are no disinterested directors, or if the disinterested directors so direct, by independent legal counsel (who may, to the extent permitted by applicable law, be regular legal counsel to the Company) in a written opinion, or (iv) by the stockholders of the Company.

13.8 Remedies. The right to indemnification or advancement of Expenses as provided by this Agreement shall be enforceable by the Employee in any court of competent jurisdiction. Unless otherwise required by law, the burden of proving that indemnification is not appropriate shall be on the Company. Neither the failure of the Company to have made a determination prior to the commencement of such action that indemnification is proper in the circumstances because the Employee has met the applicable standard of conduct, nor an actual determination by the Company pursuant to Section 13.7 that the Employee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the Employee has not met the applicable standard of conduct. The Employee’s expenses (of the type described in the definition of “Expenses” below) reasonably incurred in connection with successfully establishing the Employee’s right to indemnification, in whole or in part, in any such Proceeding shall also be indemnified by the Company.

13.9 Partial Indemnification. If the Employee is entitled under any provision of this Agreement to indemnification by the Company for some or a portion of the Expenses, judgments, fines, penalties or amounts paid in settlement actually and reasonably incurred by or on behalf of the Employee in connection with any Proceeding but not, however, for the total

amount thereof, the Company shall nevertheless indemnify the Employee for the portion of such Expenses, judgments, fines, penalties or amounts paid in settlement to which the Employee is entitled.

13.10 Subrogation. In the event of any payment under this Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of the Employee, who shall execute all papers required and take all action necessary to secure such rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such rights.

13.11 Indemnification Hereunder Not Exclusive. The indemnification and advancement of Expenses provided by this Agreement shall not be deemed exclusive of any other rights to which the Employee may be entitled under the Company’s Certification of Incorporation, the By-Laws, any other agreement, any vote of stockholders or disinterested directors, the General Corporation Law of Delaware, any other law (common or statutory), or otherwise, both as to action in the Employee’s official capacity and as to action in another capacity while holding office for the Company. Nothing contained in this Agreement shall be deemed to prohibit the Company from purchasing and maintaining insurance, at its expense, to protect itself or the Employee against any expense, liability or loss incurred by it or the Employee in any such capacity, or arising out of the Employee’s status as such, whether or not the Employee would be indemnified against such expense, liability or loss under this Agreement; provided that the Company shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable hereunder if and to the extent that the Employee has otherwise actually received such payment under any insurance policy, contract, agreement or otherwise.

13.12 Definitions. As used in this Section 13:

(a) The term “Proceeding” shall include any threatened, pending or completed action, suit, arbitration, alternative dispute resolution proceeding, administrative hearing or other proceeding, whether brought by or in the right of the Company or otherwise and whether of a civil, criminal, administrative or investigative nature, and any appeal therefrom.

(b) The term “Corporate Status” shall mean the status of a person who is or was a director or officer of the Company, or is or was serving, or has agreed to serve, at the request of the Company, as a director, officer, partner, trustee, member, employee or agent of another corporation, partnership, joint venture, trust, limited liability company or other enterprise.

(c) The term “Expenses” shall include, without limitation, attorneys’ fees, retainers, court costs, transcript costs, fees and expenses of experts, travel expenses, duplicating costs, printing and binding costs, telephone charges, postage, delivery service fees and other disbursements or expenses of the types customarily incurred in connection with investigations, judicial or administrative proceedings or appeals, but shall not include the amount of judgments, fines or penalties against the Employee or amounts paid in settlement in connection with such matters.

(d) References to “other enterprise” shall include employee benefit plans; references to “fines” shall include any excise tax assessed with respect to any employee benefit plan; references to “serving at the request of the Company” shall include any service as a director, officer, employee or agent of the Company which imposes duties on, or involves services by, such director, officer, employee, or agent with respect to an employee benefit plan, its participants, or beneficiaries; and a person who acted in good faith and in a manner such person reasonably believed to be in the interests of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the Company” as referred to in this Agreement.

13.13 Savings Clause. If this Section 13 or any portion thereof shall be invalidated on any ground by any court of competent jurisdiction, then the Company shall nevertheless indemnify the Employee as to Expenses, judgments, fines, penalties and amounts paid in settlement with respect to any Proceeding to the full extent permitted by any applicable portion of this Section 13 that shall not have been invalidated and to the fullest extent permitted by applicable law.

13.14 Applicable Law. Notwithstanding anything herein to the contrary, this Section 13 shall be governed by, and construed and enforced in accordance with, the laws of the State of Delaware. The Employee may elect to have the right to indemnification or reimbursement or advancement of Expenses interpreted on the basis of the applicable law in effect at the time of the occurrence of the event or events giving rise to the applicable Proceeding, to the extent permitted by law, or on the basis of the applicable law in effect at the time such indemnification or reimbursement or advancement of Expenses is sought. Such election shall be made, by a notice in writing to the Company, at the time indemnification or reimbursement or advancement of Expenses is sought; provided, however, that if no such notice is given, and if the General Corporation Law of Delaware is amended, or other Delaware law is enacted, to permit further indemnification of the directors and officers, then the Employee shall be indemnified to the fullest extent permitted under the General Corporation Law, as so amended, or by such other Delaware law, as so enacted.

13.15 Enforcement. The Company expressly confirms and agrees that it has entered into this Agreement in order to induce the Employee to serve as an officer of the Company, among other things, and acknowledges that the Employee is relying upon this Agreement in continuing in such capacity.

13.16 Consent to Suit. In the case of any dispute under or in connection with this Section 13, the Employee may only bring suit against the Company in the Court of Chancery of the State of Delaware. The Employee hereby consents to the exclusive jurisdiction and venue of the courts of the State of Delaware, and the Employee hereby waives any claim the Employee may have at any time as to forum non conveniens with respect to such venue. The Company shall have the right to institute any legal action arising out of or relating to this Section 13 in any court of competent jurisdiction. Any judgment entered against either of the parties in any proceeding hereunder may be entered and enforced by any court of competent jurisdiction.

14. Section 409A of the Internal Revenue Code.

14.1 The following rules shall apply with respect to distribution of the payments and benefits, if any, to be provided to the Employee under Section 5:

(a) It is intended that each installment of the payments and benefits provided under Section 5 shall be treated as a separate “payment” for purposes of Section 409A. Neither the Company nor the Employee shall have the right to accelerate or defer the delivery of any such payments or benefits except to the extent specifically permitted or required by Section 409A;

(b) If, as of the date of the “separation from service” of the Employee from the Company, the Employee is not a “specified employee” (each within the meaning of Section 409A), then each installment of the payments and benefits shall be made on the dates and terms set forth in Section 5; and

(c) If, as of the date of the “separation from service” of the Employee from the Company, the Employee is a “specified employee” (each, for purposes of this Agreement, within the meaning of Section 409A), as determined by the Company in accordance with its procedures, by which determination the Employee hereby agrees that he is bound, then:

(i) Each installment of the payments and benefits due under Section 5 that are paid within the Short-Term Deferral Period (as hereinafter defined) shall be treated as a short-term deferral within the meaning of Treasury Regulation Section 1.409A-1(b)(4) to the maximum extent permissible under Section 409A. For purposes of this Agreement, the “Short-Term Deferral Period” means the period ending on the later of the 15th day of the third month following the end of the Employee’s tax year in which the Employee’s separation from service occurs and the 15th day of the third month following the end of the Company’s tax year in which the Employee’s separation from service occurs;

(ii) Each installment of the payments and benefits due under Section 5 that is not paid within the Short-Term Deferral Period and that would, absent this subsection, be paid within the six-month period following the “separation from service” of the Employee of the Company shall not be paid until the date that is six months and one day after such separation from service (or, if earlier, 10 days following the death of the Employee), with any such installments that are required to be delayed being accumulated during the six-month period and paid in a lump sum on the date that is six months and one day following the Employee’s separation from service (or, with respect to payment after death, as soon as reasonably practicable and within the time limits permitted by Section 409A), and any remaining payments will be paid on their original schedule and any subsequent installments, if any, being paid in accordance with the dates and terms set forth herein; provided, however, that the preceding provisions of this sentence shall not apply to any installment of payments and benefits if and to the maximum extent that that such installment is deemed to be paid under a separation pay plan that does not provide for a deferral of compensation by reason

of the application of Treasury Regulation 1.409A-1(b)(9)(iii) (relating to separation pay upon an involuntary separation from service) or Treasury Regulation 1.409A-1(b)(9)(iv) (relating to reimbursements and certain other separation payments). Any installments that qualify for the exception under Treasury Regulation Section 1.409A-1(b)(9)(iii) must be paid no later than the last day of the second taxable year of the Employee following the taxable year of the Employee in which the separation from service occurs. A comparable six month delay will apply to any other payments and benefits received by Employee under other compensatory arrangements if and to the extent required for compliance with Section 409A.

(d) The determination of whether and when the Employee’s separation from service from the Company has occurred shall be made and in a manner consistent with, and based on the presumptions set forth in, Treasury Regulation Section 1.409A-1(h). Solely for purposes of this subsection (d), “Company” shall include all persons with whom the Company would be considered a single employer under Section 414(b) and 414(c) of the Code.

14.2 All payments and benefits provided under this Agreement are intended to either comply with or be exempt from Section 409A and this Agreement shall be administered and construed accordingly. The Company makes no representations or warranty and shall have no liability to the Employee or any other person if any payments made under this Agreement are determined to constitute deferred compensation subject to Section 409A but not to satisfy the conditions of that section. All reimbursements and in-kind benefits provided under this Agreement shall be made or provided in accordance with the requirements of Section 409A to the extent that such reimbursements or in-kind benefits are subject to Section 409A, including, where applicable, the requirements that (i) any reimbursement is for expenses incurred during the Employee’s lifetime (or during a shorter period of time specified in this Agreement), (ii) the amount of expenses eligible for reimbursement during a calendar year may not affect the expenses eligible for reimbursement in any other calendar year, (iii) the reimbursement of an eligible expense will be made on or before the last day of the calendar year following the year in which the expense is incurred and (iv) the right to reimbursement is not subject to set off or liquidation or exchange for any other benefit.

15. Parachute Treatment. Notwithstanding any other provision of this Agreement to the contrary, if payments made hereunder or otherwise are considered “excess parachute payments” under Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”), then such excess parachute payments plus any other payments made by the Company and its affiliates that the Employee is entitled to receive that are considered excess parachute payments shall be limited to the greatest amount that may be paid to the Employee under Section 280G of the Code without causing any loss of deduction to the Company under such Code Section, but only if, by reason of such reduction, the “Net After Tax Benefit” (as defined below) to the Employee shall exceed the net after tax benefit if such reduction was not made. “Net After Tax Benefit” for purposes of this Agreement shall mean the sum of (i) the total amounts payable to the Employee that would constitute an “excess parachute payment” within the meaning of Section 280G of the

Code less (ii) the amount of federal, state and other income taxes payable with respect to the foregoing calculated at the maximum marginal tax rate for each year in which the foregoing shall be paid to the Employee (based upon the rate in effect for such year as set forth in the Code at the time of termination of employment or the applicable change in control), less (iii) the amount of excise taxes imposed with respect to the payments and benefits described above by Section 4999 of the Code. The determination of whether payments would be considered excess parachute payments and the calculation of all the amounts referred to in this section shall be made reasonably and in good faith by the parties, provided, that if the parties cannot agree, then such determination (and supporting calculations) shall be made by attorneys, accountants, or an executive compensation consulting firm each as selected by the Company at the expense of the Company (the “280G Service Providers”). Any determination by the 280G Service Providers made in good faith shall be binding upon the Company and the Employee.

16. Counterparts. This Agreement may be executed in two counterparts, each of which shall be deemed to be an original, but all of which together shall constitute one and the same instrument.
