Overview

We are a clinical-stage biopharmaceutical company developing therapeutic product candidates for metabolic diseases by targeting the biology of human aging. Our technology platform and differentiated human datasets enable us to identify promising targets based on insights into molecular changes that drive aging.

In January 2025, we announced the nomination of our lead program, BGE-102, a potent, structurally novel, orally available, brain-penetrant small-molecule NLRP3 inhibitor. BGE-102 has a distinct mechanism and binding site from other NLRP3 inhibitors in development with issued patents covering both composition of matter and claims for the unique binding site.

In December 2025, we announced that BGE-102 was well-tolerated in Single Ascending Dose (SAD) and initial Multiple Ascending Dose (MAD) cohorts, with a pharmacokinetic profile supporting once-daily oral dosing, strong target engagement and high brain penetration.

We intend to advance BGE-102 in two therapeutic areas: cardiometabolic disease and ophthalmology.

Our first therapeutic area for BGE-102 is cardiometabolic disease, with a focus on atherosclerotic cardiovascular disease (ASCVD) risk reduction. Chronic systemic inflammation, as measured by high-sensitivity C-reactive protein (hsCRP), is an independent risk factor for cardiovascular events that is not adequately addressed by current lipid-lowering and antihypertensive therapies. In January 2026, we announced additional positive interim Phase 1 data, demonstrating potential for best-in-class hsCRP reduction in participants with elevated cardiovascular risk. In obese participants with elevated hsCRP, BGE-102 demonstrated an 86% median reduction in hsCRP at Day 14, with 93% of participants achieving hsCRP levels below 2 mg/L — the threshold associated with a 25% reduction in major adverse cardiovascular events. This level of hsCRP reduction is comparable to injectable anti-IL-6 monoclonal antibodies in clinical development for ASCVD, but achieved with once-daily oral dosing. We anticipate full Phase 1 SAD / MAD clinical trial results in the first half of 2026. We plan to initiate a Phase 2a proof-of-concept trial in patients with obesity and elevated hsCRP in the first half of 2026, with results anticipated by 2026 year end.

Our second therapeutic area for BGE-102 is ophthalmology. Diabetic macular edema (DME) is our first proof-of-concept indication in this area. DME affects approximately 1 million patients in the United States, and current intravitreal therapies face significant unmet need due to high injection burden and a substantial refractory population — approximately 45% of patients demonstrate refractoriness to anti-vascular endothelial growth factor (VEGF) therapy. In a preclinical model of DME, oral BGE-102 demonstrated dose-dependent preservation of retinal vascular integrity, achieving near-complete protection from vascular leakage and up to 90% preservation of microvascular integrity. We plan to initiate a Phase 1b/2a proof-of-concept trial in DME in mid-2026 with results anticipated in mid-2027. The goal is to demonstrate ocular target engagement, supporting future development across inflammation-driven retinal diseases.

Beyond NLRP3 inhibition, we are also developing novel apelin receptor APJ agonists for obesity, including programs targeting both oral and parenteral (subcutaneous) administration. In preclinical obesity models, APJ agonism has demonstrated the ability to more than double the weight loss induced by a glucagon-like peptide-1 receptor (GLP-1R) agonist while also restoring healthy body composition and improving muscle function. In June 2025, we announced an option agreement with JiKang Therapeutics for a novel APJ agonist antibody, as well as the filing of a U.S. provisional patent for novel small molecule APJ agonists. We intend to file the first Investigational New Drug application (IND) for an APJ program by 2026 year end.

110

We are also advancing earlier stage platform-derived programs in collaboration with Eli Lilly and Company (Lilly), and have an ongoing target discovery collaboration with Novartis Pharma AG (Novartis).

Our portfolio of product candidates and ongoing collaborations are summarized in the figure below:

Since our inception in 2015, we have devoted substantially all of our efforts to organizing and staffing our company, business planning, raising capital, establishing our intellectual property portfolio, acquiring or discovering product candidates, research and development activities for our product candidates, establishing arrangements with third parties for the manufacture of our product candidates and component materials, and providing general and administrative support for these operations. We do not have any products approved for sale and have not generated any revenue from product sales. Our primary uses of capital are, and we expect will continue to be, research and development services, compensation and related expenses and general overhead costs.

We have incurred significant operating losses and negative cash flows since inception. Our ability to generate product revenue sufficient to achieve profitability will depend heavily on the successful development and eventual commercialization of any future product candidates. Our net losses were $80.6 million and $71.1 million for the years ended December 31, 2025 and 2024, respectively. As of December 31, 2025, we had an accumulated deficit of $333.4 million. We expect to continue to incur net operating losses for the foreseeable future, and we expect our research and development expenses, general and administrative expenses, and capital expenditures will increase substantially in connection with our ongoing activities, particularly if, and as, we:

•

continue to progress the development of our lead product candidate, BGE-102;

•

explore additional indications for our existing product candidates;

•

discover and develop any future product candidates;

•

obtain, expand, maintain, defend and enforce our intellectual property portfolio;

•

manufacture, or have manufactured, preclinical, clinical and potentially commercial supplies of BGE-102 and any future product candidates;

•

seek regulatory approvals for BGE-102 or for any future product candidates that successfully complete clinical trials, if any;

•

establish a sales, marketing and distribution infrastructure to commercialize BGE-102 or any future product candidates, if approved;

•

seek to identify, evaluate and establish licenses, collaborations or other strategic partnerships;

111

•

hire additional clinical, scientific and management personnel, as well as administrative staff to support the growth of our business; and

•

add operational, financial and management information systems and personnel.

Our net losses may fluctuate significantly from period to period, depending on the timing of factors above.

We will not generate revenue from product sales unless and until we successfully complete clinical development and obtain regulatory approval for BGE-102 or a future product candidate. In addition, if we obtain regulatory approval for BGE-102 or a future product candidate and do not enter into a third-party commercialization partnership, we expect to incur significant expenses related to developing our commercialization capability to support product sales, marketing, manufacturing and distribution activities.

As a result, we will need substantial additional funding to support our continuing operations and pursue our growth strategy. Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through equity offerings, debt financings or other capital sources, which could include licenses, collaborations, or other strategic partnerships. Adequate additional funds may not be available to us on acceptable terms, or at all. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interests of our existing stockholders may be diluted, and the terms of these securities may include liquidation or other preferences that could adversely affect the rights of such stockholders. Debt financing, if available, may involve agreements that include restrictive covenants that limit our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends, which could adversely impact our ability to conduct our business. If we raise additional funds through licenses, collaborations, or other strategic partnerships with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research program or product candidates, or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves. There is no assurance that we will ever be profitable or generate positive cash flow from operating activities. Our ability to raise additional funds may also be adversely impacted by potential worsening global macroeconomic, industry and market conditions in either domestic or international markets, as well as economic conditions specifically affecting industries in which we operate, including but not limited to, actual or perceived instability in the banking industry, potential uncertainty with respect to the U.S. federal debt ceiling and budget and any future government shutdowns related thereto, labor shortages, supply chain disruptions, potential recession, inflation and changing interest rates, significant trade or regulatory developments, including tariffs or shifting priorities within the U.S. Food and Drug Administration, and political instability and military hostilities in multiple geographies, such as the conflicts in Ukraine, the Middle East, and tensions between China and Taiwan.

Because of the numerous risks and uncertainties associated with development of product candidates, we are unable to predict the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability. Even if we are able to generate product sales, we may not become profitable. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and be forced to reduce or terminate our operations.

We oversee and manage third party Contract Development and Manufacturing Organizations (CDMOs) to support development and manufacture of our future product candidates. We expect to enter into commercial supply agreements with commercial manufacturers prior to any potential regulatory approval of any future product candidates. We believe our current manufacturers are able to supply the upcoming preclinical and clinical trials of future product candidates. Additional CDMOs may be on-boarded at later stages of clinical and commercial development for future product candidates.

As of December 31, 2025, we had $285.1 million in cash, cash equivalents and marketable securities. Based on our current operating plan, we estimate that our existing cash, cash equivalents and marketable securities as of the filing date of this Annual Report will be sufficient to fund our operations and capital expenses through 2029. However, we have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect. See the section titled "Liquidity and Capital Resources" included elsewhere in this Annual Report.

Collaboration Agreement with Novartis Pharma AG

On December 16, 2024, we entered into a collaboration agreement with Novartis to identify and validate novel therapeutic drug targets by investigating the biological mechanisms that drive diseases related to aging and mediate the beneficial effects of physical exercise (the "Novartis Agreement").

112

Under the terms of the Novartis Agreement, we are obligated to perform additional analyses on our longitudinal human aging cohort datasets, to expand data included in our discovery platform, and perform other activities to enable the identification and validation of novel therapeutic drug targets.

In consideration for the rights granted under the Novartis Agreement, we have received and may receive upfront payments and research funding of up to $20.0 million, and up to $530.0 million in future long-term research, development, and commercial milestones. We and Novartis each have the right to advance novel targets discovered under the Novartis Agreement and are each eligible to receive reciprocal success milestones and receive tiered royalties on net sales of licensed products.

Collaboration revenue of $9.0 million was recognized under the Novartis Agreement in the year ended December 31, 2025. No collaboration revenue was recognized under the Novartis Agreement in the year ended December 31, 2024. During the year ended December 31, 2025, we recorded $6.7 million in revenue that was included in deferred revenue as of December 31, 2024 and $2.2 million in revenue related to research funding for reimbursable costs incurred during the year ended December 31, 2025. Deferred revenue related to the Novartis Agreement amounted to $5.8 million and $12.5 million as of December 31, 2025, and December 31, 2024, respectively, of which $5.8 million and $7.8 million, respectively, was included in current liabilities within the consolidated balance sheets.

Components of Our Results of Operations

Revenue

We have not generated any product revenue since our inception and do not expect to generate any revenue from the sale of products in the near future, if at all. If our development efforts for BGE-102 or other product candidates that we may develop in the future are successful and result in marketing approval, we may generate revenue from product sales.

We have recognized, and expect to recognize, collaboration revenue in the future from the Novartis Agreement, which may include amounts related to upfront payments, milestone payments, and research and development funding.

Operating Expenses

Our operating expenses consist of (i) research and development expenses and (ii) general and administrative expenses.

Research and Development Expense

Research and development expenses account for a significant portion of our operating expenses and consist primarily of costs incurred in connection with the discovery, preclinical development, clinical development and manufacturing of our former lead product candidate, azelaprag, our lead product candidate, BGE-102, and other potential future product candidates, and include:

Direct Costs:

•

expenses incurred under agreements with CROs that are primarily engaged in the oversight and conduct of our clinical trials; CDMOs that are primarily engaged to provide drug substance and product for our clinical trials and preclinical studies, research and development programs, as well as investigative sites and consultants that conduct our clinical trials, preclinical studies and other scientific development services;

•

the cost of acquiring and manufacturing preclinical and clinical trial materials, including manufacturing registration and validation batches;

•

costs of outside consultants, including their fees and related travel expenses;

•

costs related to compliance with quality and regulatory requirements; and

•

payments made under third-party licensing agreements.

113

Indirect Costs:

•

personnel-related expenses including, salaries, bonuses, benefits, stock-based compensation expenses and other related costs for individuals involved in research and development activities; and

•

allocated facilities and other expenses not directly tied to a program.

We expense research and development costs as incurred. We recognize direct development costs based on an evaluation of the progress to completion of specific tasks using information provided to us by our vendors or our estimate of the level of service that has been performed at each reporting date. Payments for these development activities are based on the terms of the individual agreements, which may differ from the pattern of costs incurred, and are reflected in our financial statements as prepaid expenses or accrued expenses.

A significant portion of our research and development costs to date have been third-party direct costs, which we disclose on an individual product candidate basis after the completion of IND-enabling activities for that product candidate. However, our indirect costs are not directly tied to any one program and are deployed across our programs. As such, we do not track these costs on a specific program basis. We utilize third party contractors for our research and development activities and CDMOs for our manufacturing activities and we do not have our own manufacturing facilities.

Research and development activities are central to our business model. We expect that our research and development expenses will continue to increase substantially for the foreseeable future as we progress BGE-102 into additional clinical trials, continue to discover and develop additional product candidates, expand our headcount and costs related to our existing and potential future intellectual property licenses. 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. There are numerous factors associated with the successful development and commercialization of any product candidates we may develop in the future, including future trial design and various regulatory requirements, many of which cannot be determined with accuracy at this time based on our stage of development. Additionally, future commercial and regulatory factors beyond our control will impact our clinical development program and plans.

Our research and development expenses may vary significantly in the future based on factors, such as:

•

the number and scope of preclinical and IND-enabling studies;

•

per patient trial costs;

•

the number of trials required for approval;

•

the number of sites included in the trials;

•

the countries in which the trials are conducted;

•

the length of time required to enroll eligible patients;

•

the number of patients that participate in the trials;

•

the drop-out or discontinuation rates of patients;

•

potential additional safety monitoring requested by regulatory agencies;

•

the duration of patient participation in the trials and follow-up;

•

the cost and timing of manufacturing our product candidates;

•

the phase of development of our product candidates;

•

the efficacy and safety profile of our product candidates;

•

the extent to which we establish additional collaboration or license agreements; and

•

whether we choose to partner any of our product candidates and the terms of such partnership.

Changes in the outcome of any of these variables with respect to the development of our lead product candidate, BGE-102, or any future product candidates in preclinical and clinical development could mean a significant change in the costs and timing associated with the development of these product candidates. For example, if the FDA, European Medicines Agency or another regulatory authority were to delay our planned start of clinical trials or require us to conduct clinical trials or other

114

testing beyond those that we currently expect, or if we experience significant delays in enrollment in any clinical trials following the applicable regulatory authority’s acceptance and clearance, we could be required to expend significant additional financial resources and time to complete clinical development than we currently expect. We may never obtain regulatory approval for any product candidates that we develop.

The successful development of BGE-102 or any other product candidates we may develop in the future is highly uncertain. Therefore, we cannot reasonably estimate or know the nature, timing and estimated costs of the efforts that will be necessary to complete the development and commercialization of BGE-102, our APJ programs or any future product candidates we may develop. We are also unable to predict when, if ever, material net cash inflows will commence from the sale of BGE-102 or any future product candidate, if approved. This is due to the numerous risks and uncertainties associated with product development.

General and Administrative Expense

General and administrative expenses consist primarily of personnel-related expenses, including salaries, bonuses, benefits, and stock-based compensation expenses for individuals in executive, finance, corporate, business development, and administrative functions. Other significant general and administrative expenses include legal fees relating to patent, intellectual property and corporate matters, and fees paid for accounting, consulting and other professional services, allocated expenses for rent, insurance and other operating costs.

We expect that our general and administrative expenses will continue to increase in the foreseeable future as our business expands to support our continued research and development activities, including any future clinical trials. These increases will likely include increased costs related to the hiring of additional personnel and fees to outside consultants, among other expenses. We also anticipate increased expenses associated with being a public company, including costs for audit, legal, regulatory and tax-related services related to compliance with the rules and regulations of the SEC, listing standards applicable to companies listed on a national securities exchange, director and officer insurance premiums and investor relations costs. In addition, if we obtain regulatory approval for any product candidates we may develop in the future and do not enter into a third-party commercialization collaboration, we expect to incur significant expenses related to building a sales and marketing team to support product sales, marketing and distribution activities.

Other Income (Expense), Net

Interest Expense

Interest expense consists of interest incurred on both our convertible promissory notes and term loan.

Interest and Other Income (Expense), Net

Interest and other income (expense), net primarily consist of interest income generated from interest bearing cash, cash equivalents and marketable securities.

Gain (Loss) from Changes in Fair Value of Warrants

Gain (loss) on changes in fair value consists of assessed changes in fair value of warrants to purchase our common stock.

Loss on Extinguishment of Convertible Promissory Notes

Loss on extinguishment of convertible promissory notes consists of the difference between the carrying value of our convertible promissory notes (including accrued interest) and related embedded derivative liability and the fair value of shares issued upon conversion of our convertible promissory notes into our Series D-1 Redeemable Convertible Preferred Stock in February 2024.

Income Taxes

Since our inception, we have not recorded any income tax benefits for the net losses we have incurred in each period or for our research and development tax credits, as we believe, based upon the weight of available evidence, that it is more likely than not that all of our net operating loss carryforwards and tax credits will not be realized. As of December 31, 2025, we had U.S. federal and state net operating loss carryforwards of $204.1 million and $15.9 million, respectively, which expire at various

115

dates beginning in 2035. These attributes may be subject to Section 382 limitation and we have not performed a formal assessment. As of December 31, 2025 and December 31, 2024, we have recorded a full valuation allowance against our deferred tax assets.

Loss on extinguishment of debt — (250 ) 250 (100 )%

Collaboration Revenue

Collaboration Revenue for the year ended December 31, 2025 was $9.0 million, compared to no collaboration revenue for the year ended December 31, 2024. The $9.0 million increase in collaboration revenue was the result of revenue recognized under the Novartis Agreement, as work commenced in 2025.

Research and Development Expenses

The following table summarizes our research and development expenses for each of the periods presented (in thousands, except percentages):

Years Ended December 31,

Direct costs:

Indirect costs:

116

Research and development expenses increased by $14.9 million from $59.0 million for the year ended December 31, 2024 to approximately $73.9 million for the year ended December 31, 2025. The increase in research and development expenses was primarily attributable to a $24.3 million increase in direct costs related to other programs, which was primarily related to work performed under the Novartis Agreement as well as licensing, discovery, and development activities related to our novel apelin receptor APJ agonist programs during the year ended December 31, 2025. Additionally, direct costs related to our BGE-102 program increased $14.4 million associated with IND-enabling activities, drug-product manufacturing and our ongoing Phase 1 SAD / MAD clinical trial.

Further contributing to the increase in research and development expenses was a $1.2 million increase in personnel-related expenses, driven by stock-based compensation grants to employees, and a $1.4 million increase in allocated facility and other expenses primarily related to facility expenses for our Emeryville Lease (defined below) and an increase in non-program specific consulting fees. These higher costs were partially offset by a $26.4 million reduction in azelaprag direct costs as development was terminated in January 2025.

General and Administrative Expenses

General and administrative expenses increased by $8.6 million from $19.2 million for the year ended December 31, 2024 to $27.8 million for the year ended December 31, 2025. The increase was primarily driven by a $3.9 million increase in personnel-related expenses, largely due to an increase in stock-based compensation expense associated with new option grants issued to employees, executives, board members and advisors. Additionally contributing to the increase in general and administrative expenses was a $2.9 million increase in legal fees, a $1.2 million increase in franchise taxes and insurance, primarily related to our public company director and officer insurance policy, and a $0.6 million increase in information technology and equipment costs, primarily related to software expense.

Other Income (Expense), Net

Other income (expense), net increased by approximately $5.1 million from $7.1 million for the year ended December 31, 2024 to $12.2 million of other income for the year ended December 31, 2025. This increase in other income was primarily attributable to a $3.5 million increase in interest income driven by our higher cash, cash equivalents and marketable securities balance. Further contributing to the increase in other income was a $1.7 million decrease in interest expense, a $0.3 million decrease in loss on extinguishment of debt related to our convertible promissory notes that converted into Series D-1 redeemable convertible preferred stock in February 2024, partially offset by a $0.3 million increase in loss from changes in fair value on warrants.

Liquidity and Capital Resources

Sources of Liquidity

Since our inception, we have incurred significant losses in each period and on an aggregate basis. We have not yet commercialized any product candidates, and we do not expect to generate revenue from sales of any product candidates for the foreseeable future, if at all. As of December 31, 2025, we had $285.1 million in cash, cash equivalents and marketable securities and we had an accumulated deficit of $333.4 million.

In May 2022, we entered into a loan and security agreement (the Loan Agreement) with SVB Innovative Credit Growth Fund IX, LP and Innovative Credit Growth Fund VIII-A, LP pursuant to which we were able to borrow up to an aggregate of $25.0 million across two potential tranches until December 31, 2023 (the Term Loan). The Loan Agreement has a floating interest rate of the higher of the Wall Street Journal Prime rate plus 4.00% or 7.5%. The amounts borrowed under the Loan Agreement are scheduled to mature on April 1, 2026 and commencing on November 1, 2023 we are required to make monthly principal payments. In addition, we will also be required to pay a final payment fee equal to 4.4% of the total amount borrowed. As of December 31, 2025, we had $2.0 million outstanding under the Loan Agreement. See Note 5 to our consolidated financial statements included elsewhere in this Annual Report for further discussion of the Loan Agreement.

In October 2025, we filed a shelf registration statement on Form S-3 (the “Shelf Registration Statement”) which became effective through the operation of law in November 2025. The Shelf Registration Statement permits the offering of up to $250.0 million aggregate dollar amount of shares of our common stock or preferred stock, debt securities, warrants to purchase our common stock, preferred stock or debt securities, subscription rights to purchase our common stock, preferred stock or debt securities and/or units consisting of some or all of these securities, in one or more offerings and in any combination. In

117

connection with the Shelf Registration Statement, we entered into a Sales Agreement (the “Sales Agreement”) with Leerink Partners LLC (“Leerink”) relating to the applicable terms of at-the-market equity offerings (the “ATM Facility”) pursuant to which we may, but are not obligated to, offer and sell, from time to time, shares of our common stock with an aggregate offering price up to $75.0 million through Leerink, as sales agent in the ATM Facility.

During the year ended December 31, 2025, we sold an aggregate of 1,400,000 shares of our common stock through our ATM Facility pursuant to the Sales Agreement. The gross proceeds from these sales were approximately $17.6 million, before deducting sales agent commission and offering costs of approximately $0.5 million, resulting in net proceeds of approximately $17.1 million.

In January 2026, we completed an underwritten public offering of our common stock, issuing 5,897,435 shares at a public offering price of $19.50 per share for net proceeds of $107.6 million, after underwriting discounts and commissions and estimated offering costs (the “January 2026 Offering”). The January 2026 Offering included a 30-day option for the underwriters to purchase up to 884,615 additional shares.

In February 2026, we issued 884,615 shares of our common stock upon exercise of the underwriters’ option in the January 2026 Offering, resulting in net proceeds of $16.2 million, net of underwriting discounts and commissions.

Cash Flows

The following table provides information regarding our cash flows for each of the periods presented (in thousands):

Years Ended December 31,

Net cash used in operating activities $ (81,627 ) $ (51,522 )

Net cash used in investing activities (95,216 ) (366 )

Net cash provided by financing activities 11,469 381,199

Effects of exchange rate changes on cash and cash equivalents (87 ) 81

Net increase (decrease) in cash and cash equivalents $ (165,461 ) $ 329,392

Net Cash Used in Operating Activities

Net cash used in operating activities for the year ended December 31, 2025 was $81.6 million, and was primarily due to our net loss of $80.6 million and a $11.8 million change in operating assets and liabilities, primarily driven by a $6.7 million decrease in deferred revenue related to revenue recognized under the Novartis Agreement. These changes were partially offset by non-cash adjustments of $10.8 million, which was primarily driven by $11.7 million in stock-based compensation expense and partially offset by $1.6 million in accretion of net investment discounts related to marketable securities.

Net cash used in operating activities for the year ended December 31, 2024 was $51.5 million, and was primarily due to our net loss of $71.1 million, which included non-cash charges of $7.0 million related to stock-based compensation expense, $1.0 million related to non-cash interest expense, and a $0.3 million loss on extinguishment of convertible promissory notes. Also contributing to net cash used in operating activities for the year ended December 31, 2024 was a $3.3 million decrease in deferred grant income, partially offset by a $12.5 million increase in deferred revenue related to the Novartis Agreement.

Net Cash Used in Investing Activities

Net cash used in investing activities for the year ended December 31, 2025 was $95.2 million and included cash outflows of $154.8 million related to the purchase of marketable securities as well as $0.7 million related to the purchase of property and equipment. These changes were partially offset by maturities of marketable securities of $60.3 million.

Net cash used in investing activities for the year ended December 31, 2024 was $0.4 million, resulting from $0.4 million in purchases of property and equipment.

118

Net Cash Provided by Financing Activities

Net cash provided by financing activities during the year ended December 31, 2025 was $11.5 million, driven primarily by $17.1 million in net proceeds from the issuance of common stock through our ATM facility, after commissions and issuance costs, and $0.7 million of proceeds from stock option exercises. These amounts were partially offset by $6.0 million in principal payments on our Term Loan and $0.3 million of deferred offering costs paid.

Net cash provided by financing activities during the year ended December 31, 2024 was $381.2 million, resulting from $207.2 million in net proceeds from our IPO, $9.9 million in net proceeds from the sale of our common stock through a private placement transaction, $169.5 million in net proceeds from the issuance and sale of our Series D redeemable convertible preferred stock and $0.6 million in proceeds from stock option exercises partially offset by $6.0 million in principal payments on our Term Loan.

Funding Requirements

Our primary uses of capital are, and we expect will continue to be, research and development services, compensation and related expenses and general overhead costs. We expect to continue to incur significant expenses and operating losses for the foreseeable future.

Based on our current operating plan, we estimate that our existing cash, cash equivalents and marketable securities as of the filing date of this Annual Report will be sufficient to fund our operations and capital expenses through 2029. However, we have based this estimate on assumptions that may prove to be wrong, and we could exhaust our available capital resources sooner than we expect.

Because of the numerous risks and uncertainties associated with research, development and commercialization of product candidates, we are unable to estimate the exact amount of our working capital requirements. Our future funding requirements will depend on, and could increase significantly as a result of, many factors, including:

•

the timing, cost and progress of preclinical and clinical development activities;

•

the cost of regulatory submissions and timing of regulatory approvals;

•

the number and scope of preclinical and clinical programs we decide to pursue;

•

the progress of the development efforts of parties with whom we may in the future enter into licenses, collaborations or other strategic partnerships;

•

the cash requirements of any future acquisitions or discovery of product candidates;

•

our ability to establish and maintain licenses, collaborations or other strategic partnerships with third parties on favorable terms, if at all;

•

the costs involved in prosecuting and enforcing patent and other intellectual property claims;

•

the costs of manufacturing our product candidates by third parties;

•

the cost of commercialization activities of any future product candidates are approved for sale, including marketing, sales and distribution costs;

•

our efforts to enhance operational systems and hire additional personnel, including personnel to support development of our product candidates; and

•

our need to implement additional internal systems and infrastructure, including financial and reporting systems to satisfy our obligations as a public company.

A change in the outcome of any of these or other variables with respect to the development of BGE-102 or any product or development candidate we may develop in the future could significantly change the costs and timing associated with our development plans. Further, our operating plans may change in the future, and we may need additional funds to meet operational needs and capital requirements associated with such operating plans.

Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through equity offerings, debt financings or other capital sources, which could include licenses, collaborations, or other strategic partnerships. We currently have no credit facility or committed sources of capital. Adequate additional funds may not be

119

available to us on acceptable terms, or at all. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interests of our existing stockholders may be diluted, and the terms of these securities may include liquidation or other preferences that could adversely affect the rights of such stockholders. Debt financing, if available, may involve agreements that include restrictive covenants that limit our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends, that could adversely impact our ability to conduct our business. If we raise additional funds through licenses, collaborations, or other strategic partnerships with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research program or product candidates, or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves. There is no assurance that we will ever be profitable or generate positive cash flow from operating activities.

Contractual Obligations and Other Commitments

Lease Obligations

We lease office and lab space at our corporate headquarters in Emeryville, CA (the Emeryville Lease). The Emeryville lease is accounted for as an operating lease and expires on February 28, 2031. Non-cancellable base rent lease obligations as of December 31, 2025 were $3.9 million, of which $0.6 million is due within the next 12 months.

Purchase and Other Obligations

We enter into contracts in the normal course of business with CROs, CDMOs and other third-party vendors for preclinical research studies and testing, clinical trials and testing and manufacturing services. Most contracts do not contain minimum purchase commitments and are cancellable by us upon written notice. Payments due upon cancellation consist of payments for services provided or expenses incurred, including non-cancelable obligations of our service provided up to one year after the date of cancellation.

Critical Accounting Policies and Estimates

Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with United States Generally Accepted Accounting Principles (GAAP). The preparation of these consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets and liabilities and the reported amounts of income and expenses during the reporting period. We continually evaluate our estimates and judgments used in preparing our consolidated financial statements and related disclosures. All estimates affect reported amounts of assets, liabilities, income and expenses. These estimates and judgments are also based on historical experience and other factors that are believed to be reasonable under the circumstances. Materially different results can occur as circumstances change and additional information becomes known.

While our significant accounting policies are more fully described in "Notes to the Consolidated Financial Statements - Note 2" appearing elsewhere in this Annual Report, we believe that the following accounting policies are the most critical for fully understanding and evaluating our financial condition and results of operations.

Accrued and Prepaid Research and Development Expenses

As part of the process of preparing our consolidated financial statements, we are required to estimate our accrued and prepaid third-party research and development expenses as of each balance sheet date. This process involves reviewing open contracts and purchase orders, communicating with our personnel to identify services that have been performed on our behalf, and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of the actual cost. The majority of our service providers invoice us monthly in arrears for services performed or when contractual milestones are met. We make estimates of our accrued and prepaid expenses as of each balance sheet date based on facts and circumstances known to us at that time. We periodically confirm the accuracy of our estimates with the service providers and make adjustments if necessary. The significant estimates in our accrued and prepaid research and development expenses include the costs incurred for services performed by our vendors in connection with research and development activities for which we have not yet been invoiced.

We base our expenses related to research and development activities on our estimates of the services received and efforts expended pursuant to quotes and contracts with vendors that conduct research and development activities on our behalf. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment

120

flows. There may be instances in which payments made to our vendors will exceed the level of services provided and result in a prepayment of the research and development expense. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or prepaid balance accordingly. Non-refundable advance payments for goods and services that will be used in future research and development activities are expensed when the activity has been performed or when the goods have been received rather than when the payment is made.

Although we do not expect our estimates to be materially different from amounts incurred, if our estimates of the status and timing of services performed differ from the actual status and timing of services performed, it could result in us reporting amounts that are too high or too low in any particular period. To date, there have been no material differences between our estimates of such expenses and the amounts incurred.

Stock-Based Compensation

Compensation cost for our stock-based payments to employees, non-employees and directors, are based on estimated fair value of the awards on the date of grant. Our stock-based compensation awards are generally subject to service-based vesting conditions. Compensation expense related to awards to employees, directors and non-employees with service-based vesting conditions is recognized on a straight-line basis based on the grant date fair value over the associated service period of the award, which is generally the vesting term. The fair value of each stock option is estimated on the grant date using the Black-Scholes option pricing model, which requires inputs based on certain subjective assumptions, including:

•

Risk-Free Interest Rate—The risk-free interest rate is based on the U.S. Treasury zero coupon issues in effect at the time of grant for periods corresponding with the expected term of option.

•

Expected Term—The expected term of options represents the average period the stock options are expected to remain outstanding. As we do not have sufficient historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior, the expected term of options granted is derived from the average midpoint between the weighted average vesting and the contractual term, also known as the simplified method.

•

Expected Volatility—Since we do not have sufficient history to estimate the expected volatility of our common stock price, expected volatility is estimated based on the average historical volatility of similar entities with publicly traded shares. When selecting comparable publicly traded biopharmaceutical companies on which we have based our expected stock price volatility, we selected companies with comparable characteristics, including enterprise value, risk profiles, development stage, and with historical share price information sufficient to meet the expected term of the stock-based awards.

•

Expected Dividend Yield—We have never paid dividends on our common stock and have no plans to pay dividends on our common stock. Therefore, we used an expected dividend yield of zero.

•

Estimated Fair Value of Common Stock—Prior to our IPO, the fair value of the underlying common stock at the date of grant was determined based on a valuation of our common stock. Subsequent to our IPO, the fair value of the underlying common stock is determined based on the quoted market price of our common stock on the NASDAQ.

See Note 7 to our audited consolidated financial statements included elsewhere in this Annual Report for information concerning certain of the specific assumptions we used in applying the Black-Scholes option pricing model to determine the estimated fair value of our stock options granted in the years ended December 31, 2025 and 2024.

We recorded stock-based compensation expense of $11.7 million and $7.0 million for the years ended December 31, 2025 and 2024, respectively. As of December 31, 2025, there was $23.8 million of unrecognized stock-based compensation expense related to unvested stock options, to be recognized over a weighted-average period of 2.5 years. In future periods, we expect our stock-based compensation expense to increase, due in part to our existing unrecognized stock-based compensation expense and as we grant additional stock-based awards to continue to attract and retain our employees.

Revenue Recognition

Our revenues are generated primarily through collaborative research, license, development and commercialization agreements. The terms of these agreements generally contain multiple elements, or deliverables, which may include (i) licenses, or options to obtain licenses, to use our technology, (ii) research and development activities to be performed on behalf of the collaborative partner, and (iii) in certain cases, services in connection with the manufacturing of preclinical and clinical

121

material. Payments we receive under these arrangements typically include one or more of the following: non-refundable, upfront license fees; option exercise fees; funding of research and/or development efforts; clinical and development, regulatory, and sales milestone payments; and royalties on future product sales. We classify payments received under these agreements as revenues within our statements of operations.

ASC 606, Revenue from Contracts with Customers, applies to all contracts with customers, except for contracts that are within the scope of other standards. Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation.

At contract inception, once the contract is determined to be within the scope of ASC 606, we evaluate the performance obligations promised in the contract that are based on goods and services that will be transferred to the customer and determine whether those obligations are both (i) capable of being distinct and (ii) distinct in the context of the contract. Goods or services that meet these criteria are considered distinct performance obligations. If both these criteria are not met, the goods and services are combined into a single performance obligation. We then recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Arrangements that include rights to additional goods or services that are exercisable at a customer’s discretion are generally considered options. We assess if these options provide a material right to the customer and, if so, these options are considered performance obligations. The exercise of a material right is accounted for as a contract modification for accounting purposes.

We recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) each performance obligation is satisfied at a point in time or over time, and if over time this is based on the use of an output or input method.

Invoices issued as stipulated in contracts prior to revenue recognition are recorded as deferred revenue. Amounts expected to be recognized as revenue within the 12 months following the balance sheet date are classified as deferred revenue within current liabilities in our balance sheets. Amounts not expected to be recognized as revenue within the 12 months following the balance sheet date are classified as noncurrent deferred revenue. Amounts recognized as revenue, but not yet invoiced are generally recognized as contract assets in the other current assets line item in our balance sheets.

Milestone Payments – If an arrangement includes development and regulatory milestone payments, we evaluate whether the milestones are considered probable of being reached and estimate the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within our control or the licensee’s control, such as regulatory approvals, are generally not considered probable of being achieved until those approvals are received.

Royalties – For arrangements that include sales-based royalties, including milestone payments based on a level of sales, which are the result of a customer-vendor relationship and for which the license is deemed to be the predominant item to which the royalties relate, we recognize 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. To date, we have not recognized any royalty revenue resulting from any of our licensing arrangements.

Collaborative Arrangements – We have entered into collaboration agreements, which are within the scope of ASC 606, to discover, develop, manufacture and commercialize product candidates. The terms of these agreements typically contain multiple promises or obligations, which may include: (1) licenses, or options to obtain licenses, to use our technology, (2) research and development activities to be performed on behalf of the collaboration partner, and (3) in certain cases, services in connection with the manufacturing of preclinical and clinical material. Payments we receive under these arrangements typically include one or more of the following: non-refundable, upfront license fees; option exercise fees; funding of research and/or development efforts; clinical and development, regulatory, and sales milestone payments; and royalties on future product sales.

122

We analyze our collaboration arrangements to assess whether they are within the scope of ASC 808, Collaborative Arrangements, to determine whether such arrangements involve joint operating activities performed by parties that are both active participants in the activities and exposed to significant risks and rewards dependent on the commercial success of such activities. This assessment is performed throughout the life of the arrangement based on changes in the responsibilities of all parties in the arrangement. For collaboration arrangements within the scope of ASC 808 that contain multiple elements, we first determine which elements of the collaboration are deemed to be within the scope of ASC 808 and those that are more reflective of a vendor-customer relationship and, therefore, are within the scope of ASC 606. For elements of collaboration arrangements that are accounted for pursuant to ASC 808, an appropriate recognition method is determined and applied consistently, generally by analogy to ASC 606. For those elements of the arrangement that are accounted for pursuant to ASC 606, we apply the five-step model described above.

Revenue related to performance obligations satisfied over time could be materially impacted as a result of changes in the estimated research effort to satisfy performance obligations or changes in the transaction price related to variable consideration. In the year ended December 31, 2025, we did not record any cumulative catch-up adjustments on contracts.

Emerging Growth Company and Smaller Reporting Company Status

Under Section 107(b) of the JOBS Act an “emerging growth company” can delay the adoption of new or revised accounting standards until such time as those standards would apply to private companies. We have elected this exemption to delay adopting new or revised accounting standards until such time as those standards apply to private companies. Where allowable we have early adopted certain standards as described in Note 2 of our consolidated financial statements included elsewhere in this Annual Report As a result, our consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates. We will continue to remain an “emerging growth company” until the earliest of the following: (i) the last day of the fiscal year following the fifth anniversary of the date of the completion of our IPO; (ii) the last day of the fiscal year in which our total annual gross revenue is equal to or more than $1.235 billion; (iii) the date on which we have issued more than $1.0 billion in nonconvertible debt during the previous three years; or (iv) the date on which we are deemed to be a large accelerated filer under the rules of the SEC.

We are also a “smaller reporting company,” meaning that the market value of our stock held by non-affiliates is less than $700.0 million and our annual revenue is less than $100.0 million during the most recently completed fiscal year. We will continue to be a smaller reporting company if either (i) the market value of our stock held by non-affiliates is less than $250.0 million or (ii) our annual revenue is less than $100.0 million during the most recently completed fiscal year and the market value of our stock held by non-affiliates is less than $700.0 million.

If we are a smaller reporting company at the time we cease to be an emerging growth company, we may continue to rely on exemptions from certain disclosure requirements that are available to smaller reporting companies. Specifically, as a smaller reporting company we may choose to present only the two most recent fiscal years of audited financial statements in our Annual Report on Form 10-K and, similar to emerging growth companies, smaller reporting companies have reduced disclosure obligations regarding executive compensation.

123

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

We are a smaller reporting company as defined by Rule 12b-2 under the Exchange Act and are not required to provide the information otherwise required under this item.

Item 8. Financial Statements and Supplementary Data.

The financial statements required to be filed pursuant to this Item 8 are appended to this report and are incorporated herein by reference. An index of those financial statements is found in Item 15 of Part IV of this Annual Report on Form 10-K.

Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure.

None.

Item 9A. Controls and Procedures.

Evaluation of disclosure controls and procedures

Our management, with the participation of our Principal Executive Officer and Principal Financial Officer, evaluated, as of the end of the period covered by this Annual Report on Form 10-K, the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act). Our disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including the Principal Executive Officer and the Principal Financial Officer, to allow timely decisions regarding required disclosures. Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objective and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on that evaluation, our Principal Executive Officer and Principal Financial Officer concluded that our disclosure controls and procedures were effective at the reasonable assurance level as of December 31, 2025.

Management’s annual report on internal control over financial reporting

Our management, with the participation of our principal executive officer and our principal financial officer, is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. Our management conducted an assessment of the effectiveness of our internal control over financial reporting based on the criteria set forth in “Internal Control–Integrated Framework (2013)” issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management concluded that, as of December 31, 2025, our internal control over financial reporting was effective.

Attestation Report of the Registered Public Accounting Firm

This Annual Report on Form 10-K does not include an attestation report of our independent registered public accounting firm regarding internal control over financial reporting. For as long as we remain a “smaller reporting company” as defined in Item 10(f)(1) of Regulation S-K, and a non-accelerated filer as defined in the Exchange Act, we intend to take advantage of the exemption permitting us not to comply with the requirement that our independent registered public accounting firm provide an attestation on the effectiveness of our internal control over financial reporting.

Changes in internal control over financial reporting

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during the year ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

124

Item 9B. Other Information.

10b5-1 Plans

On December 16, 2025, Shane Barton, C.P.A., the Company’s Principal Accounting Officer,adopted a Rule 10b5-1 trading plan. Mr. Barton's Rule 10b5-1 trading plan is intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) and provides for the potential sale of up to 2,632 shares of the Company’s common stock held by Mr. Barton at a minimum price of $25.00 per share until June 14, 2027. Mr. Barton's Rule 10b5-1 trading plan also provides for the potential exercise and sale of up to 125,610 shares of the Company’s common stock subject to a stock option held by Mr. Barton at a minimum price of $25.00 per share until June 14, 2027.

The Rule 10b5-1 plan listed above each included a representation from the director or officer to the broker administering the plan that they were not in possession of any material nonpublic information regarding the Company or the securities subject to the plan. A similar representation was made to the Company by each director or officer in a certification provided to us in connection with the adoption of the plan under the Company’s insider trading policy. Those representations were made as of the date of adoption of each 10b5-1 plan or certification, as applicable, and speak only as of those dates. In making those representations, there is no assurance with respect to any material nonpublic information of which the director or officer was unaware, or with respect to any material nonpublic information acquired by the director or officer or the Company after the applicable date of the representation.

Item 9C. Disclosure Regarding Foreign Jurisdictions that Prevent Inspections.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors

BioAge Labs, Inc.:

Opinion on theConsolidated Financial Statements

We have audited the accompanying consolidated balance sheets of BioAge Labs, Inc. and subsidiary (the Company) as of December 31, 2025 and 2024, the related consolidated statements of operations and comprehensive loss, redeemable convertible preferred stock and stockholders’ equity (deficit), and cash flows for each of the years in the two-year period ended December 31, 2025, and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the years in the two-year period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

/s/ KPMG LLP

We have served as the Company’s auditor since 2021.

Notes to Consolidated Financial Statements

Note 1. Basis of Presentation

Nature of Business

BioAge Labs, Inc. (the “Company”), is a clinical-stage biopharmaceutical company developing therapeutic product candidates for metabolic diseases by targeting the biology of human aging. The Company's technology platform and differentiated human datasets enable us to identify promising targets based on insights into molecular changes that drive aging.

The Company was incorporated in 2015 in the State of Delaware and is headquartered in Emeryville, California.

On September 25, 2024, the Company completed its initial public offering (“IPO”) in which the Company issued and sold 11,000,000 shares of its common stock, at a public offering price of $18.00 per share and received approximately $179.6 million in net proceeds, after deducting underwriting discounts and commission of approximately $13.9 million and offering expenses of approximately $4.5 million.

On September 25, 2024, in a concurrent private placement with Sofinnova Venture Partners, XI, L.P., an existing stockholder, the Company issued and sold 588,888 shares of its common stock at a price of $18.00 per share and received approximately $9.9 million in net proceeds, after deducting placement agent fees of approximately $0.7 million.

On October 1, 2024, the underwriters of the Company's IPO elected to exercise in full their option to purchase 1,650,000 additional shares of the Company's common stock at the IPO price of $18.00 per share. The Company received approximately $27.6 million in net proceeds, after deducting underwriting discounts and commissions of approximately $2.1 million.

On October 2, 2025, the Company filed a universal shelf registration statement on Form S-3 (the “Registration Statement”) with the SEC, as amended on November 5, 2025, and entered into a sales agreement with Leerink Partners LLC, under which the Company may, from time to time, offer and sell common stock having an aggregate offering value of up to $75.0 million, referred to as the “at-the-market” offering with Leerink. The Company may terminate this at-the-market program at any time, pursuant to its terms.

As of December 31, 2025, 1,400,000 shares of our common stock had been offered or sold pursuant to the “at-the-market” program with Leerink for gross proceeds of approximately $17.6 million, before deducting sales agent commission and offering costs of approximately $0.5 million, resulting in net proceeds of approximately $17.1 million.

Liquidity and Capital Resources

Since inception, the Company’s operations have consisted primarily of organizing and staffing the Company, business planning, raising capital, establishing its intellectual property portfolio, acquiring or discovering product candidates, research and development activities for its product candidates, establishing arrangements with third parties for the manufacture of its product candidates and component materials, and providing general and administrative support for these operations. The Company has not generated any product revenue to date.

The Company has incurred losses and negative cash flows from operations since inception and had an accumulated deficit of $333.4 million as of December 31, 2025. The Company anticipates incurring additional losses until such time, if ever, that it can generate significant sales of its products currently in development. As of December 31, 2025, the Company had cash, cash equivalents and marketable securities of $285.1 million, of which $4.0 million were long-term marketable securities.

Current cash, cash equivalents and marketable securities are sufficient to fund planned operations for at least one year after the date these consolidated financial statements are issued. Accordingly, these consolidated financial statements have been prepared on a going concern basis and do not include any adjustments to the amounts and classification of assets and liabilities that may be necessary in the event the Company can no longer continue as a going concern.

F-6

Until such time, if ever, the Company can generate substantial product revenues, it expects to finance its cash needs through equity offerings, debt financings or other capital sources, which could include collaborations, strategic alliances or licensing arrangements. To the extent that the Company raises additional capital through the sale of equity or convertible debt securities, the ownership interests of its existing stockholders may be diluted, and the terms of these securities may include liquidation or other preferences that could adversely affect the rights of such stockholders. Debt financing, if available, may involve agreements that include restrictive covenants that limit the Company’s ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends, that could adversely impact the Company’s ability to conduct its business. If the Company raises additional funds through collaborations, strategic alliances or licensing arrangements with third parties, the Company may have to relinquish valuable rights to the Company’s technologies, future revenue streams, research program or product candidates, or grant licenses on terms that may not be favorable to the Company. If the Company is unable to raise additional funds through equity or debt financings when needed, the Company may be required to delay, limit, reduce or terminate its product development or future commercialization efforts or grant rights to develop and market product candidates that the Company would otherwise prefer to develop and market itself.

Note 2. Basis of Presentation and Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The accompanying consolidated financial statements have been prepared in conformity with United States of America generally accepted accounting principles (“GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (the “SEC”) regarding annual financial reporting. Any reference in these notes to applicable guidance is meant to refer to GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) promulgated by the Financial Accounting Standards Board (“FASB”). The consolidated financial statements include the accounts of BioAge Labs, Inc. and its wholly owned subsidiary, BioAge Labs PTY LTD. BioAge Labs PTY LTD was incorporated in Australia in December 2020. All intercompany accounts and transactions have been eliminated in consolidation.

Reverse Stock Split

On September 17, 2024, the Company amended its amended and restated certificate of incorporation in order to effect a 1-for-4.4626 reverse stock split of its outstanding shares of common stock (the “Reverse Stock Split”). As a result of the Reverse Stock Split, every 4.4626 shares of the Company’s common stock issued or outstanding were automatically reclassified into one new share of common stock, subject to the treatment of fractional shares as described below, without any action on the part of the holders. All historical share and per-share amounts reflected throughout the accompanying consolidated financial statements have been retroactively adjusted to reflect the Reverse Stock Split as if the split occurred as of the earliest period presented. The Reverse Stock Split did not affect the number of authorized shares of common stock or the par value of the common stock. No fractional shares were issued in connection with the Reverse Stock Split.

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates.

Estimates and assumptions are periodically reviewed and the effects of revisions are reflected in the consolidated financial statements in the period they are determined to be necessary. Areas that require management’s estimates include the fair values of common and redeemable convertible preferred stock (prior to the IPO), warrant liability, embedded derivative liability, stock-based compensation expense assumptions, valuation of deferred tax assets, measure of progress toward satisfaction of the performance obligation for collaboration revenue, and accruals for research and development expenses.

Foreign Currency

Results of foreign operations are translated into U.S. dollars (reporting currency) using average exchange rates in effect during the year while assets and liabilities are translated into U.S. dollars using exchange rates in effect at the balance sheet date. The resulting foreign currency translation adjustments are recorded in accumulated other comprehensive income (loss). Transaction gains and losses resulting from exchange rate changes on transactions denominated in currencies other than the U.S. dollar are included in operations in the period in which the transaction occurs.

F-7

Segments

Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision-maker ("CODM"), in making decisions regarding resource allocation and performance assessment. The Company has determined that its chief executive officer is the CODM. The Company operates and manages its business as one reportable and operating segment, which is the business of extending healthy human life by targeting molecular causes of aging. The Company’s CODM reviews financial information on an aggregate basis for allocating and evaluating financial performance. All long-lived assets are maintained in, and all losses are attributable to, the United States of America. For further detail, see Note 13 to the consolidated financial statements.

Cash, Cash Equivalents and Marketable Securities

The Company considers all highly liquid investments that have original maturities of three months or less when acquired to be cash equivalents. Cash, and cash equivalents as of December 31, 2025 consisted of bank deposit, money market funds, commercial paper and corporate debt securities. As of December 31, 2024 cash and cash equivalents consisted of bank deposits and money market mutual funds.

Marketable securities consist of high-grade debt securities including corporate debt, commercial paper, U.S. government and U.S. government agency securities, and foreign corporate debt securities. Marketable securities with maturities within twelve months from the balance sheet date are classified as short-term marketable securities and those with maturities over twelve months from the balance sheet date are classified as long-term marketable securities. The Company classifies all marketable securities as available-for-sale, which are recorded at fair value. Unrealized gains and losses are included in accumulated other comprehensive income (loss) in stockholders’ equity. As of and for the year ended December 31, 2025, the Company did not have any allowance for credit losses or impairments of its marketable securities. The Company did not have any marketable securities as of December 31, 2024.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to credit risk consist primarily of accounts receivable, cash, cash equivalents and marketable securities. Management monitors exposure to credit risk on an ongoing basis.

The Company invests its excess cash in investment-grade, liquid instruments in accordance with its investment policy. The Company maintains cash balances at financial institutions that may exceed federally insured limits and is exposed to credit risk in the event of a default by the financial institutions holding its cash and by issuers of its cash equivalents and marketable securities. The Company has not experienced any losses on its deposits of cash, cash equivalents or marketable securities to date.

As of December 31, 2025, one customer accounted for 100% of the Company’s accounts receivable. For the year ended December 31, 2025, the same customer accounted for 100% of the Company’s revenue.

The Company has no financial instruments with off-balance sheet risk of loss.

Risks and Uncertainties

The Company faces risks and uncertainties associated with companies in the biotechnology industry, including but not limited to the uncertainty of success of its preclinical studies and clinical trials, regulatory approval of product candidates, uncertainty of market acceptance of products, competition from substitute products and larger companies, the need for additional financing, compliance with government regulations, dependence on third parties, recruiting and retaining skilled personnel, and dependence on key members of management.

The Company’s product candidates require approvals from the U.S. Food and Drug Administration (“FDA”) and comparable foreign regulatory agencies prior to commercial sales in their respective jurisdictions. There can be no assurance that any product candidates will receive the necessary approvals. If the Company was denied approval, approval was delayed or the Company was unable to maintain approval for any product candidate, it could have a materially adverse impact on the Company.

F-8

Property and Equipment, Net

Property and equipment, net is carried at cost less accumulated depreciation. Depreciation is computed over the estimated useful lives of the respective assets using the straight-line method. Useful lives of property and equipment range from three to five years. Operating lease leasehold improvements are amortized over the lesser of the useful lives of the leasehold improvements or the lease term. Upon retirement or sale, the costs of the assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain or loss is credited or charged to operations. Maintenance and repairs are expensed as incurred. Asset improvements are capitalized.

Impairment of Long-lived Assets

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows which the assets are expected to generate. If such assets are considered to be impaired, the impairment is measured by the excess of the carrying amount of the assets over fair value less the costs to sell the assets, generally determined using the projected discounted future net cash flows arising from the asset. The Company did not recognize any impairment of long-lived assets during the years ended December 31, 2025 or 2024.

Redeemable Convertible Preferred Stock

The Company records redeemable convertible preferred stock net of issuance costs on the date of issuance, which represents the carrying value. Redeemable convertible preferred stock is classified outside of stockholders’ deficit as temporary equity on the accompanying consolidated balance sheets as events triggering the liquidation preferences, including a deemed liquidation event, are not solely within the Company’s control.

Upon the closing of the IPO, all of the Company’s outstanding shares of redeemable convertible preferred stock automatically converted into 20,854,632 shares of common stock. As of December 31, 2025, the Company had no redeemable convertible preferred stock outstanding.

Term Loan

Term loans are measured at net proceeds less debt discounts and issuance costs, which are accreted to the face value of the term loan over its expected term using the effective interest method. The Company considers whether there are any embedded features in its debt instruments that require bifurcation and separate accounting as derivative financial instruments pursuant to ASC Topic 815, Derivatives and Hedging (Note 5).

Warrant Liability

Freestanding warrants for the Company’s common stock are classified as liabilities and recorded at fair value, with any change in fair value recognized as a component of other income (expense). Such warrant liabilities are subject to re-measurement at each balance sheet date until the earlier of the exercise of the warrants, expiration, or the completion of a change in control event. Upon exercise, the warrant liability would be reclassified to additional paid-in capital, at its then fair value.

Research and Development Expenses

Research and development costs are expensed as incurred and include all direct and indirect costs associated with the development of the Company’s product candidates and other research programs. These expenses consist primarily of personnel costs, stock-based compensation charges, consulting fees, and payments to third parties for research, development, and manufacturing services as well as other allocated facility-related costs and overhead expenses. Nonrefundable advance payments for goods or services that will be used or rendered for future research and development activities are capitalized and expensed as the goods are delivered or the related services are performed.

Accrued Research and Development Expenses

The Company records accruals for estimated costs of research, preclinical studies, clinical trials, and manufacturing, which are significant components of research and development expenses. A substantial portion of the Company’s ongoing research and development activities is conducted by third-party service providers, clinical research organizations (“CROs”),

F-9

and clinical manufacturing organizations (“CMOs”). The Company’s contracts with CROs generally include pass-through fees such as laboratory supplies and services, regulatory expenses, investigator fees, travel costs and other miscellaneous costs, including shipping and printing fees. The financial terms of these contracts are subject to negotiations, which vary from contract to contract and may result in payment flows that do not match the periods over which materials or services are provided to the Company under such contracts. The Company accrues the costs incurred under agreements with these third parties based on estimates of actual work completed in accordance with the respective agreements. The Company determines the estimated costs through discussions with internal personnel and external service providers as to the progress, or stage of completion or actual timeline (start-date and end-date) of the services and the agreed-upon fees to be paid for such services. In the event the Company makes advance payments, the payments are recorded as a prepaid expense and recognized as the services are performed.

As actual costs become known, including subsequent to the reporting date, the Company adjusts its accruals. Although the Company does not expect its estimates to be materially different from amounts actually incurred, such estimates for the status and timing of services performed relative to the actual status and timing of services performed may vary and could result in the Company reporting amounts that are too high or too low in any particular period. The Company’s accrual is dependent, in part, upon the receipt of timely and accurate reporting from CROs and other third-party vendors. Variations in the assumptions used to estimate accruals including, but not limited to, the number of patients enrolled, the rate of patient enrollment and the actual services performed, may vary from the Company’s estimates, resulting in adjustments to clinical trial expenses in future periods. Changes in these estimates that result in material changes to the Company’s accruals could materially affect its financial condition and results of operations.

Revenue Recognition for Contracts with Customers

ASC 606 applies to all contracts with customers, except for contracts that are within the scope of other standards. Under ASC 606, an entity recognizes revenue when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the entity performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation.

At contract inception, once the contract is determined to be within the scope of ASC 606, the Company evaluates the performance obligations promised in the contract that are based on goods and services that will be transferred to the customer and determines whether those obligations are both (i) capable of being distinct and (ii) distinct in the context of the contract. Goods or services that meet these criteria are considered distinct performance obligations. If both these criteria are not met, the goods and services are combined into a single performance obligation. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Arrangements that include rights to additional goods or services that are exercisable at a customer’s discretion are generally considered options. The Company assesses if these options provide a material right to the customer and if so, these options are considered performance obligations. The exercise of a material right is accounted for as a contract modification for accounting purposes.

The Company recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) each performance obligation is satisfied at a point in time or over time, and if over time this is based on the use of an output or input method.

Invoices issued as stipulated in contracts prior to revenue recognition are recorded as deferred revenue. Amounts expected to be recognized as revenue within the 12 months following the balance sheet date are classified as deferred revenue within current liabilities in the accompanying balance sheets. Amounts not expected to be recognized as revenue within the 12 months following the balance sheet date are classified as noncurrent deferred revenue. Amounts recognized as revenue, but not yet invoiced are generally recognized as contract assets in the other current assets line item in the accompanying balance sheets.

Milestone Payments – If an arrangement includes development and regulatory milestone payments, the Company evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within the Company’s or the licensee’s control, such as regulatory approvals, are not considered probable of being achieved until those approvals are received and therefore revenue recognized is constrained as management is unable to assert that a reversal of revenue would not be probable. The transaction price is then allocated to each performance obligation on a relative standalone selling price basis, for which the Company recognizes revenue as or when the performance obligations under the contract are satisfied. At the end of each subsequent reporting period, the Company re-evaluates the probability of achievement of such development

F-10

milestones and any related constraint, and, if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect collaboration revenues and earnings in the period of adjustment.

Royalties – For arrangements that include sales-based royalties, including milestone payments based on a level of sales, which are the result of a customer-vendor relationship and for which 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 linked to some or all of the royalty has been satisfied or partially satisfied. To date, the Company has not recognized any royalty revenue resulting from any of its licensing arrangements.

Collaborative Arrangements – The Company has entered into collaboration agreements, which are within the scope of ASC 606, to discover, develop, manufacture and commercialize product candidates. The terms of these agreements typically contain multiple promises or obligations, which may include: (1) licenses, or options to obtain licenses, to use the Company’s technology, (2) research and development activities to be performed on behalf of the collaboration partner, and (3) in certain cases, services in connection with the manufacturing of preclinical and clinical material. Payments the Company receives under these arrangements typically include one or more of the following: non-refundable, upfront license fees; option exercise fees; funding of research and/or development efforts; clinical and development, regulatory, and sales milestone payments; and royalties on future product sales.

The Company analyzes its collaboration arrangements to assess whether the collaboration agreements are within the scope of ASC 808, Collaborative Arrangements (“ASC 808”) to determine whether such arrangements involve joint operating activities performed by parties that are both active participants in the activities and exposed to significant risks and rewards dependent on the commercial success of such activities. This assessment is performed throughout the life of the arrangement based on changes in the responsibilities of all parties in the arrangement. For collaboration arrangements within the scope of ASC 808 that contain multiple elements, the Company first determines which elements of the collaboration are deemed to be within the scope of ASC 808 and those that are more reflective of a vendor-customer relationship and, therefore, are within the scope of ASC 606. For elements of collaboration arrangements that are accounted for pursuant to ASC 808, an appropriate recognition method is determined and applied consistently, generally by analogy to ASC 606. For those elements of the arrangement that are accounted for pursuant to ASC 606, the Company applies the five-step model described above.

For additional discussion of accounting for collaboration revenues, see Note 9, Collaboration Agreements.

Stock-Based Compensation

The Company’s stock-based compensation program allows for grants of stock options and restricted stock awards. Grants are awarded to employees and non-employees, including directors.

Compensation cost for the Company’s stock-based payments to employees, non-employees and directors, are based on estimated fair value of the awards on the date of grant. The Company estimates the fair value of options granted using the Black-Scholes option pricing model for stock option grants to both employees and non-employees.

The Company’s stock-based compensation awards are subject to service-based vesting conditions. Compensation expense related to awards to employees, directors and non-employees with service-based vesting conditions is recognized on a straight-line basis over the requisite service period, net of actual forfeitures.

Income Taxes

Income taxes are accounted for under the asset and liability method in accordance with ASC Topic 740, Income Taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to the differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and the operating loss and tax credit carry forwards. Deferred tax assets and liabilities are measured at the balance sheet date using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that these assets may not be realized. The Company determines whether it is more-likely-than-not that a tax position will be sustained upon examination. If it is not more-likely-than-not that a position will be sustained, none of the benefit attributable to the position is recognized. The tax benefit to be recognized for any tax position that meets the more-likely-than-not recognition threshold is calculated as the largest

F-11

amount that is more than 50% likely of being realized upon resolution of the contingency. No interest or penalties were incurred by the Company related to uncertain tax positions in the years ended December 31, 2025 or 2024.

Leases

The Company determines if an arrangement is a lease at the inception of the arrangement. Operating leases are included in right-of-use assets, current portion of operating lease liability, and operating lease liability, net of current portion in the accompanying consolidated balance sheets. Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. In determining the present value of lease payments, the Company uses its incremental borrowing rate based on the information available at the lease commencement date. The operating lease right-of-use assets also include any lease payments made and exclude lease incentives. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise any such options. Lease expense is recognized on a straight-line basis over the expected lease term. The Company has elected not to separate lease and non-lease components, such as common area maintenance charges, and instead it accounts for these as a single lease component. Leases with an initial term of 12 months or less are not recorded on the balance sheet, unless they include an option to purchase the underlying asset or to extend the lease that the Company is reasonably certain to exercise.

Comprehensive Loss

Comprehensive loss is defined as a change in equity of a business enterprise during a period, resulting from transactions from non-owner sources. Comprehensive loss is comprised of net loss and other comprehensive income (loss). The Company’s other comprehensive loss consists of foreign currency translation adjustments. Total comprehensive loss for all periods presented has been disclosed in the consolidated statements of operations and comprehensive loss.

Net Loss Per Share Attributable to Common Stockholders

Basic net loss per share attributable to common stockholders is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, without consideration for potentially dilutive securities.

Diluted net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common stock and potentially dilutive securities outstanding for the period. For purposes of the diluted net loss per share attributable to common stockholders’ calculation, redeemable convertible preferred stock, stock options, and warrants are considered to be potentially dilutive securities.

Prior to the Company's Initial Public Offering and related conversion of redeemable convertible preferred stock into common shares, the Company applied the two-class method to calculate its basic and diluted net loss per share attributable to common stockholders as the Company has issued shares that meet the definition of participating securities. The two-class method is an earnings allocation formula that treats a participating security as having rights to earnings that otherwise would have been available to common stockholders. Participating securities consist of common stock and redeemable convertible preferred stock. The Company’s participating securities contractually entitle the holders of such shares to participate in dividends, but do not contractually require the holders of such shares to participate in losses of the Company. Accordingly, in periods in which the Company reports a net loss, such losses are not allocated to such participating securities.

Accordingly, in periods in which the Company reports a net loss, diluted net loss per share attributable to common stockholders is the same as basic net loss per share attributable to common stockholders, since dilutive common shares are not assumed to have been issued if their effect is anti-dilutive.

Recently Adopted and Recently Issued Accounting Pronouncements

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, to improve its income tax disclosure requirements. Under the ASU, entities must annually (i) disclose specific categories in the rate reconciliation, (ii) provide additional information for reconciling items that meet a quantitative threshold, and (iii) disclose more detailed information about income taxes paid, including by jurisdiction; pretax income (or loss) from continuing operations; and income tax expense (or benefit). The Company adopted ASU 2023-09 effective December 31, 2025. Refer to Note 10, Income Taxes, included in these notes to the consolidated financial statements for further details.

F-12

In November 2024, the FASB issued ASU 2024-03 Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This standard calls for enhanced disclosures about components of expense captions on the face of the income statement. This standard will be effective for fiscal years beginning after December 15, 2026, with early adoption permitted and the option for retrospective application. This ASU will result in the required additional disclosures being included in the Company's consolidated financial statements, once adopted, and will have no impacts on our financial condition and results of operations.

Note 3. Fair Value Measurements

Fair Value of Financial Instruments

GAAP establishes a fair value hierarchy for instruments measured at fair value that distinguishes between assumptions based on market data (observable inputs) and the Company’s own assumptions (unobservable inputs). Observable inputs are inputs that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Company.

Unobservable inputs are inputs that reflect the Company’s assumptions about the inputs that market participants would use in pricing the asset or liability and are developed based on the best information available in the circumstances.

Fair value is established as the exchange price, or exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As a basis for considering market participant assumptions in fair value measurements, an established three-tier fair value hierarchy distinguishes between the following:

•

Level 1 inputs are quoted prices in active markets that are accessible at the market date for identical assets or liabilities.

•

Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly.

•

Level 3 inputs are unobservable inputs that reflect the Company’s own assumptions about the assumptions market participants would use in pricing the assets or liability. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by the Company in determining fair value is greatest for instruments categorized in Level 3. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value instrument.

The carrying amounts of the Company’s other current assets, accounts payable, accrued expenses and other current liabilities reported in the consolidated financial statements approximate their fair values due to their short-term nature.

Cash Equivalents and Marketable Securities

Cash equivalents include U.S. government obligation money market mutual funds, commercial paper and treasury bills that have a maturity of three months or less from the original acquisition date. The Company’s money market funds and treasury bills are classified using Level 1 inputs within the fair value hierarchy because they are valued using quoted market prices. U.S. government bonds are included within Level 1 of the fair value hierarchy because they are valued using quoted market prices. Corporate debt securities, commercial paper and U.S. government agency bonds are classified within Level 2 of the fair value hierarchy as they take into consideration valuations obtained from third-party pricing services. The pricing services utilize industry standard valuation models, including both income-based and market-based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate the fair value. These inputs include reported trades of and broker/dealer quotes on similar securities, issuer credit spreads, benchmark securities, prepayment/default projections based on historical data and other observable inputs.
