Bicara Therapeutics Inc.

1. Description of Business, Organization, and Liquidity

Bicara Therapeutics Inc. (“Bicara” or the “Company”) was incorporated in the state of Delaware in December 2018 and is a clinical-stage biopharmaceutical company based in Boston, Massachusetts. The Company is committed to bringing transformative bifunctional therapies to patients with solid tumors. Its lead program ficerafusp alfa is a bifunctional antibody that combines a clinically validated epidermal growth factor receptor directed monoclonal antibody bound to a human transforming growth factor beta ligand trap.

Since inception, the Company has operated in the preclinical and clinical stages and has devoted substantially all of its time and efforts to performing research and development activities, raising capital, and recruiting management and technical staff to support these operations. The Company is subject to risks and uncertainties common to early-stage companies in the biotechnology industry including, but not limited to, risks associated with the successful research, development and manufacturing of product candidates, competition from other companies, dependence on key personnel, protection of intellectual property, compliance with government regulations and the ability to secure additional capital to fund operations. Current and future programs will require significant research and development efforts, including extensive preclinical and clinical testing and regulatory approval prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel, and infrastructure. Even if our product development efforts are successful, it is uncertain when, if ever, the Company will realize significant revenue from product sales.

The Company historically has funded its operations from the issuance of common stock in connection with its initial public offering (“IPO”), issuance of common stock in connection with its at-the-market offering program (the “ATM Program”), issuance of equity securities in a public offering in February 2026, redeemable convertible preferred stock and through debt financing.

On September 16, 2024, the Company closed its IPO, through which it issued 20,125,000 shares of common stock with par value of $0.0001 per share and a purchase price of $18.00 per share. The Company raised net proceeds of $332.4 million from the issuance of common stock.

In December 2025, the Company issued 1,604,000 shares of common stock with par value of $0.0001 per share through the ATM Program and raised net proceeds of $29.5 million.

In February 2026, the Company issued and sold 8,581,250 shares of its common stock, including 1,406,250 shares pursuant to the exercise of the underwriters’ option to purchase additional shares, at a price to the public of $16.00 per share. Further, in lieu of common stock to certain investors, the Company sold pre-funded warrants to purchase 2,200,000 shares of common stock at a public offering price of $15.9999 per pre-funded warrant, which represents the per share public offering price of each share of common stock less the $0.0001 per share exercise price for each pre-funded warrant. As a result of the offering, the Company received approximately $161.8 million in net proceeds.

The Company has incurred operating losses since inception and expects such losses and negative operating cash flows to continue for the foreseeable future. As of March 31, 2026, the Company had cash, cash equivalents and marketable securities of$539.8 million and an accumulated deficitof$415.2 million.

The Company expects that its cash, cash equivalents and marketable securities as of March 31, 2026 of$539.8 million will be sufficient to fund the operating expenditures and capital expenditure requirements necessary to advance its research efforts and clinical trials for at least one year from the date of issuance of these unaudited condensed consolidated financial statements.

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) Any reference in these notes to applicable guidance is meant to refer to the authoritative GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (“FASB”). The accompanying condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities and commitments in the ordinary course of business.

The Company’s unaudited condensed consolidated financial statements include the financial position, results of operations and cash flows of Bicara. The Company’s unaudited condensed consolidated financial statements are denominated in U.S. dollars. The unaudited condensed consolidated financial statements include the accounts of the Company and its wholly owned, controlled subsidiary. All intercompany transactions and balances have been eliminated in consolidation.

Unaudited Interim Condensed Consolidated Financial Statements

The condensed consolidated balance sheet as of March 31, 2026, condensed consolidated statements of comprehensive loss, condensed consolidated statement of stockholders' equity for the three months ended March 31, 2026 and 2025, and condensed consolidated cash flows for the three months ended March 31, 2026 and 2025 and related notes to condensed consolidated financial statements are unaudited. These unaudited interim condensed consolidated financial statements have been prepared on the same basis as the Company’s annual consolidated financial statements and, in the opinion of management, reflect all adjustments (consisting only of normal recurring adjustments) that are necessary for the fair statement of the Company’s condensed consolidated financial position, results of operations and cash flows for the periods presented. The condensed consolidated results of operations for the three months ended March 31, 2026 are not necessarily indicative of the results to be expected for the full year or for any other future annual or interim period. The condensed consolidated balance sheet as of December 31, 2025 included herein was derived from the audited consolidated financial statements as of that date. As permitted under U.S. GAAP, certain notes and other information have been omitted from the interim unaudited condensed consolidated financial statements presented in this Quarterly Report on Form 10-Q. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the Company’s most recent Annual Report on Form 10-K for the year ended December 31, 2025 (the "Form 10-K").

Emerging Growth Company Status

Bicara is an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"), and we may take advantage of reduced reporting requirements that are otherwise applicable to public companies. The Company may take advantage of these exemptions until it is no longer an emerging growth company. Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the extended transition period afforded by the JOBS Act for the implementation of new or revised accounting standards. Bicara has elected to use the extended transition period for complying with new or revised accounting standards; and as a result of this election, its financial statements may not be comparable to companies that comply with public company effective dates. The Company may take advantage of these exemptions up until the last day of the fiscal year following the fifth anniversary of its IPO or such earlier time that Bicara is no longer an emerging growth company. Bicara would cease to be an emerging growth company if it has more than $1.235 billion in total annual gross revenue, it has more than $700.0 million in market value of its stock held by non-affiliates (and it has been a public company for at least 12 months and has filed one annual report on Form 10-K), or it issues more than $1.0 billion of non-convertible debt securities over a three-year period.

Use of Estimates

The preparation of unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses and the related disclosure of contingent assets and liabilities as of and during the reporting period. The Company bases its estimates on historical experience when available and on other assumptions that management believes are reasonable under the circumstances. Significant estimates and assumptions reflected in these unaudited condensed consolidated financial statements include but are not limited to: the estimated costs of research and development activities, and the fair values of pre-IPO common stock and stock awards and associated stock-based compensation expense. The Company assesses estimates on an ongoing basis; however, actual results could materially differ from those estimates.

Marketable Securities

Marketable securities consist of obligations of, and issues guaranteed by the U.S. Treasury, U.S. Agencies and U.S. Government Sponsored Enterprises.

The Company's marketable securities are classified as available-for-sale and are carried at fair value. The Company classifies all available-for-sale securities as current assets. Marketable securities are classified as current assets because they are available to fund current operations.

Any unrealized holding gains or losses on debt securities, including their tax effect, are reported as components of Other comprehensive loss in the condensed consolidated statement of comprehensive loss. Realized gains and losses, included in Interest and other income, net in the condensed consolidated statement of comprehensive loss, are determined using the specific identification method for determining the cost of securities sold.

Declines in fair value below amortized cost related to credit losses (i.e., impairment due to credit losses) are included in the condensed consolidated statement of comprehensive loss, with a corresponding allowance established. If the estimate of expected credit losses decreases in subsequent periods, the Company will reverse the credit losses through current period earnings and adjust the allowance accordingly.

Research and Development Expense

Research and development costs are expensed as incurred in accordance with ASC 730, Research and Development(“ASC 730”). Research and development expenses include costs directly attributable to the conduct of research and development programs, including compensation costs, which includes salaries and benefits, stock-based compensation expense and the cost of services provided by outside contractors.

The Company capitalizes advance payments for goods or services that will be used or rendered for future research and development activities and recognizes expense as the related goods are delivered or services are performed. The Company also records expenses and accruals for estimated costs of research and development activities, including third party contract services for clinical research and contract manufacturing. The Company bases its estimates on the best information available at the time. Costs for certain research and development activities are recognized based on the pattern of performance of the individual arrangements, which may differ from the pattern of billings incurred, and are reflected in the condensed consolidated financial statements as prepaid expenses or as accrued research and development expenses.

The financial terms of these agreements are subject to negotiation, vary from contract to contract, and may result in uneven payment flows to the Company’s vendors. Billing terms and payments are reviewed by management to ensure estimates of outstanding obligations are appropriate as of period end. Tracking the progress of completion for clinical trial and contract manufacturing activities performed by third parties allows the Company to record the appropriate expense and accruals under the terms of the agreements.

General and Administrative Expense

General and administrative expenses consist primarily of salaries and related benefits, including share-based compensation expense, related to the Company's executive, finance and other support functions. Other general and administrative expenses include professional fees for legal, auditing, tax, consulting services, investor relations, IT and office expenses, rent and insurance.

Stock-Based Compensation

The Company accounts for stock-based employee and nonemployee compensation awards in accordance with provisions of ASC 718, Compensation—Stock Compensation(“ASC 718”). ASC 718 requires the recognition of stock-based compensation expense, using a fair-value based method, for costs related to all stock-based compensation awards. We use the Black-Scholes option-pricing model to determine the fair value of options. The Black-Scholes option-pricing model requires the use of judgment to develop input assumptions, some of which are highly subjective, including: (i) the fair value of our common stock on the date of grant; (ii) the expected term of the award; (iii) the expected volatility; (iv) the risk-free interest rate; and (v) expected dividends. In applying these assumptions, we consider the following factors:

Fair Value of Common Stock: The Company’s common stock is listed on the Nasdaq Global Market and its value is determined by the market price on the Nasdaq Global Market as of the date of the grant.

Expected Term: The expected term represents the period that the options granted are expected to be outstanding and is determined using the simplified method (based on the mid-point between the vesting date and the end of the contractual term). The expected life is applied to the stock option grant group as a whole as we do not expect substantially different exercise or post-vesting termination behavior among our employee population.

Expected Volatility: We used an average historical stock price volatility of comparable public companies within the biotechnology and pharmaceutical industry that were deemed to be representative of future stock price trends due to absence of an active market for the Company’s common stock.

Risk-Free Interest Rate: We based the risk-free interest rate over the expected term of the options based on the constant maturity rate of U.S. Treasury securities with similar maturities as of the date of the grant.

Expected Dividend: We have not paid and do not anticipate paying any dividends in the near future. Therefore, the expected dividend yield was zero.

For awards that vest based solely on achievement of a service condition, the Company recognizes expense on a straight-line basis over the period during which the award holder provides such services. The Company recognizes forfeitures as they occur and reverses any previously recognized compensation cost associated with forfeited awards. In accordance with ASU 2018-07, the Company accounts for share-based compensation for awards granted to non-employees in a similar fashion to the way it accounts for share-based compensation awards to employees.

Warrants

Management assesses warrants to determine whether they should be classified as equity or liability. If the classification is determined to be equity, proceeds received for the warrants are recorded as an increase to additional paid-in capital in the condensed consolidated balance sheets. If classified as a liability, the Company records the warrant as a liability on its consolidated balance sheet and remeasures this liability to fair value at each reporting date and recognizes changes in the fair value of the warrant in earnings.

Net Loss Per Common Share

Basic net loss per common share is determined by dividing the net loss applicable to common shareholders by the weighted average common shares outstanding during the period. The pre-funded warrants to purchase 2,200,000 shares of common stock issued in February 2026 and outstanding as of March 31, 2026 (see Note 9) were included in computing the weighted average common shares outstanding used in calculating basic and diluted loss per share. Outstanding common stock options are excluded from the calculation of diluted net loss per share when their effect would be anti-dilutive. For the three months ended March 31, 2026 and 2025, the following potentially dilutive securities have been excluded from the computations of diluted weighted average shares outstanding as they would be anti-dilutive:

Amounts in the table above reflect the common stock equivalents of the noted instruments.

Segments

Recent Accounting Pronouncements

The Company reviews new accounting standards as they are issued by the FASB or other standard-setting bodies. The Company did not identify any new standards during the quarter ended March 31, 2026 that it believes will have a material impact on the Company’s financial statements.

Accounting Pronouncements Issued and Not Adopted

Accounting Standards Update 2024-03—Disaggregation of Income Statement Expenses (DISE). This new guidance requires all public entities to incorporate disclosures about specific types of expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses. The standard is effective prospectively for fiscal years beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption and retrospective application are permitted. We are currently evaluating the impact that ASU 2024-03 will have on our condensed consolidated financial statements.

The Company reviewed additional recent accounting pronouncements and concluded they are either not applicable or that the Company does not expect adoption to have a material effect on the unaudited condensed consolidated financial statements.

3. Fair Value Measurements

The following tables present information about the Company’s financial assets that have been measured at fair value as of March 31, 2026 and December 31, 2025 (in thousands):

As summarized in the tables immediately above, the Company held eleven debt securities that were in an unrealized loss position as of March 31, 2026. The unrealized losses at March 31, 2026 were attributable to changes in interest rates and do not represent credit losses. The Company does not intend to sell these securities, and it is not more likely than not that it will be required to sell them before recovery of their amortized cost basis. The Company heldno debt securities that were in an unrealized loss position as of December 31, 2025.

5. Leases

On August 16, 2023, the Company entered into a 2.5 years lease for 4,617 square feet of office space in Boston, Massachusetts (the “Lease Agreement”). In October 2024, the Company amended its Lease Agreement to lease an additional 4,744 square feet of office space in order to expand the Company’s headquarters to 9,361 square feet of office space. The lease required a security deposit totaling $0.1 million, which the Company has met with cash on deposit.

On June 2, 2025, the Company entered into a Sublease Agreement (the “Sublease”) with J.W. Childs Associates, L.P., as sublandlord, effective on June 4, 2025. Under the Sublease, the Company leased approximately 9,682 square feet of additional office space as part of its corporate headquarters, through June 30, 2027. The base rent of the Sublease is approximately $0.5 million per year. The Sublease required an immaterial security deposit, which the Company has satisfied with cash on deposit.

On June 3, 2025, the Company entered into a second amendment to the Lease Agreement (the Lease Agreement, together with all amendments, the “Amended Lease”) to extend the term for the 9,361 square feet of office space leased under the Amended Lease through June 30, 2027. The modification of the Lease Agreement required the Company to remeasure the value of the asset and liability in accordance with ASC 842, Leases. The base rent under the Amended Lease continues to be approximately $0.6 million per year. The remeasurement did not have a material impact on the Company's right-of-use-assets.

7. Commitments and Contingencies

Legal Matters

From time to time, the Company is involved in lawsuits, arbitrations, claims, investigations and proceedings, consisting of intellectual property, commercial, employment and other matters, which arise in the ordinary course of business. The Company makes provisions for liabilities when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated.

On October 22, 2024, a complaint was filed in federal district court in the District of Massachusetts by Y-Trap, Inc. ("Y-Trap"), naming as defendants the Company and Biocon Ltd ("Biocon"), captioned Y-Trap, Inc. v. Biocon Ltd and Bicara Therapeutics Inc., No. 24-cv-12678 (D. Mass.). On January 31, 2025, Y-Trap filed its operative amended complaint. The operative complaint alleges a claim against defendants for correction of inventorship of a number of patents, including patents alleged to be licensed to the Company relating to ficerafusp alfa. The complaint also alleges claims against defendants for unfair trade practices pursuant to Chapter 93A of the Massachusetts General Laws, unjust enrichment, and civil conspiracy. The operative complaint seeks, among other things, damages (including compensatory, enhanced, and punitive damages), an order correcting the inventorship of the patents at issue, costs and attorney’s fees, and other equitable and injunctive relief. On February 28, 2025, Biocon and Bicara moved to dismiss all of Y-Trap’s claims. On September 30, 2025, the court denied Bicara's motion. On October 30, 2025, Bicara answered the operative complaint.

9. Stock-Based Compensation

2024 Stock Option and Grant Plan

In 2024, in connection with the Company’s IPO, the board of directors adopted, and the Company’s shareholders approved the 2024 Stock Option and Grant Plan (the “2024 Plan”) under which the Company may grant equity-based incentive awards to the Company’s employees, officers, directors, consultants and other key persons of the Company and its affiliates upon whose judgment, initiative, and efforts the Company largely depends for the successful conduct of its business. Following the effectiveness of the 2024 Plan, no shares remained available for future issuance under the 2019 Stock Option and Grant Plan (as amended, the “2019 Plan”). Any other options or awards outstanding under the 2019 Plan remain outstanding and effective.

The 2024 Plan, initially allowed the Company to grant awards up to 2,453,616 shares of Common Stock, plus shares of common stock subject to awards outstanding under the 2019 Plan that are forfeited, canceled, held back upon exercise of an option or settlement of an award to cover the exercise price or tax withholding, reacquired by the Company prior to vesting, satisfied without the issuance of stock or otherwise terminated (other than by exercise). Each year starting on January 1, 2025 and on each January 1 thereafter, the number of shares of stock reserved and available for issuance under the 2024 Plan shall automatically be cumulatively increased by 5% of the outstanding shares on the immediately preceding December 31 or such lesser number of shares as approved by the Company. Through March 31, 2026, the Company issued 5,239,109 of options under the 2024 Plan. The terms of equity award agreements, including vesting requirements, were determined by the board of directors and are subject to the provisions of the 2024 Plan. Equity awards granted to employees and non-employees generally vest over afour-year period but may be granted with different vesting terms. Certain options provide for early vesting.

Stock options granted to employees and non-employees expire no more than 10 years from the date of grant and are generally service based. The 2024 Plan allows for awards to contain performance-based vesting criteria and for such awards that are deemed probable of vesting, the Company records expense in the period in which such determination is made through any estimated remaining vested period. No awards with performance-based vesting criteria have been granted.

2026 Inducement Plan

In January 2026, the Company’s board of directors adopted the Bicara Therapeutics Inc. 2026 Inducement Plan (the “Inducement Plan”) and reserved 1,000,000 shares of common stock for future issuance under the Inducement Plan.

The Inducement Plan has not been approved by the stockholders of the Company and provides for the grant of non-qualified stock options, stock appreciation rights, RSAs, RSUs, unrestricted stock awards and dividend equivalent rights to newly hired employees as a material inducement to accept employment with the Company in accordance with Nasdaq Listing Rule 5635(c)(4).

Stock-Based Compensation Expense

The Company recognized total stock-based compensation expense for non-employees and employees in its statements of comprehensive loss as follows (in thousands):

Stock Options

Stock-based compensation, measured at the grant date based on the fair value of the award, is typically recognized ratably over the requisite service period, using the straight-line method of expense attribution. When utilizing the Black-Scholes option-pricing model to determine the grant date fair value of stock options granted to employees or non-employees, we used the following weighted average assumptions:

A summary of options award activity for non-employees and employees of the Company is as follows:

(1)The aggregate intrinsic values is calculated as the difference between the exercise price of the underlying options and the fair value of the Company’s common stock on March 31, 2026 for the options that were in the money.

The weighted-average fair value of options granted during the three months ended March 31, 2026 and 2025, was $13.15 and $9.60, respectively.

The aggregate intrinsic value of options exercised for the three months ended March 31, 2026 and 2025 were $5.1 million and $0.6 million, respectively.

The Company had 8,524,479 unvested stock options outstanding as of March 31, 2026. As of March 31, 2026, total unrecognized compensation costs of $72.5 million related to unvested stock options are expected to be recognized as expense over a weighted average period of 3.1 years.

2024 Employee Stock Purchase Plan

On September 5, 2024, the Company’s board of directors adopted, and its stockholders approved, the 2024 Employee Stock Purchase Plan (the "ESPP"), which became effective September 5, 2024. The ESPP initially reserves and authorizes the issuance of up to 507,383 shares of our common stock to participating employees. The ESPP provides that the number of shares reserved and available for issuance will automatically increase on January 1, 2025 and each January 1 thereafter through January 1, 2034, by the least of (i)1,014,766 shares of common stock, (ii)1% of the sum of (A) the number of shares of our common stock issued and outstanding on the immediately preceding December 31, and (B) the number of shares of common stock issuable pursuant to the exercise of any outstanding, pre-funded warrants to acquire such common stock for a nominal exercise price on the immediately preceding December 31, or (iii) such number of shares of common stock as determined by the administrator of the ESPP. The number of shares reserved under the ESPP is subject to adjustment in the event of a stock split, stock dividend, or other change in our capitalization. There has been no activity on this plan to date, and no stock-based compensation expense was recognized during the three months ended March 31, 2026.

10. Income Taxes

Deferred tax assets and deferred tax liabilities are recognized based on temporary differences between the financial reporting and tax basis of assets and liabilities using statutory rates. A valuation allowance is recorded against deferred tax assets if it is more likely than not that some or all of the deferred tax assets will not be realized. Due to losses incurred since inception and the uncertainty surrounding the realization of the favorable tax attributes in future tax returns, the Company has recorded a full valuation allowance against the Company’s otherwise recognizable net deferred tax assets.
