AGENUS INC. AND SUBSIDIARIES

NOTES TO UNAUDITED CONDENSED CO NSOLIDATED FINANCIAL STATEMENTS

March 31, 2023

Note A - Business, Liquidity and Basis of Presentation

Agenus Inc. (including its subsidiaries, collectively referred to as “Agenus,” the “Company,” “we,” “us,” and “our”) is a clinical-stage company with a pipeline of therapies designed to activate the body’s immune system to fight cancer and infections, including immune-modulatory antibodies, adoptive cell therapies (through our subsidiary MiNK Therapeutics, Inc. (“MiNK”)) and vaccine adjuvants (through our subsidiary SaponiQx, Inc. (“SaponiQx”)). Our business is designed to drive success in Immuno-oncology (“I-O”) through speed, innovation and effective combination therapies. We believe that combination therapies and a deep understanding of each patient’s cancer will drive substantial expansion of the patient population benefiting from current and potential new I-O therapies. In addition to a diverse pipeline, we have assembled fully integrated end-to-end capabilities including novel target discovery, antibody generation, cell line development and current good manufacturing practice (“cGMP”) clinical manufacturing. We believe that these fully integrated capabilities enable us to produce novel candidates on timelines that are shorter than the industry standard. Leveraging our science and capabilities, we have forged important partnerships to advance our innovation.

We are developing a comprehensive I-O portfolio driven by the following platforms and programs, which we intend to utilize individually and in combination:

our multiple antibody discovery platforms, including our proprietary display technologies, designed to drive the discovery of future antibody candidates;
our antibody candidate programs, including our lead asset, botensilimab, an Fc-enhanced CTLA-4, for which data was presented at the 2023 American Society of Clinical Oncology – Gastrointestinal Cancers Symposium demonstrating in combination with balstilimab (PD-1) significant activity in "cold tumors," such as microsatellite stable colorectal cancer ("MSS CRC"), and for which we initiated worldwide studies in 2022 in MSS CRC, in combination with balstilimab, melanoma and pancreatic cancer;
our saponin-based vaccine adjuvant platform under SaponiQx, principally including our QS-21 STIMULON adjuvant (“QS-21 STIMULON”); and
a pipeline of novel allogeneic invariant natural killer T cell (“iNKT”) therapies to treat cancer and other immune-mediated diseases controlled by MiNK.

Our business activities include product research, preclinical and clinical development, intellectual property prosecution, manufacturing, regulatory and clinical affairs, corporate finance and development activities, and support of our collaborations. Our product candidates require successful clinical trials and approvals from regulatory agencies, as well as acceptance in the marketplace. Part of our strategy is to develop and commercialize some of our product candidates by continuing our existing arrangements with academic and corporate collaborators and licensees and by entering into new collaborations.

Our cash, cash equivalents and short-term investments at March 31, 2023 were $ 189.2 million, a decrease of $ 4.1 million from December 31, 2022 . Cash and cash equivalents of our subsidiary, MiNK, at December 31, 2022, were $ 19.6 million. MiNK cash can only be accessed by Agenus through a declaration of a dividend by the MiNK Board of Directors or through settlement of intercompany balances.

We have incurred losses since our inception. As of March 31, 2023, we had an accumulated deficit of $ 1.8 billion.

We have historically financed our operations through income and revenues generated from corporate partnerships, advance royalty sales and equity issuances . Based on our current plans and projections, we believe our cash resources of $ 189.2 million at March 31, 2023 will be sufficient to satisfy our liquidity needs for more than one year from when these financial statements were issued.

Management consistently monitors our liquidity position and has the flexibility to adjust spending as necessary to preserve and extend liquidity. We regularly assess the likelihood of success of our programs, and our funding decisions are based on these evaluations. We are prepared to discontinue funding of any activities that do not impact our core priorities and to restrict capital expenditures and/or reduce the scale of our operations. Potential funding sources may include collaborations, out-licensing and/or partnering opportunities for our portfolio programs and product candidates with multiple parties, milestone payments from our existing partnerships, additional third-party agreements, asset sales, project financing, and/or sales of equity securities.

The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information and with the instructions to Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete annual

7


consolidated financial statements. In the opinion of our management, the condensed consolidated financial statements include all normal and recurring adjustments considered necessary for a fair presentation of our financial position and operating results. All significant intercompany transactions and accounts have been eliminated in consolidation. Operating results for the three months ended March 31, 2023, are not necessarily indicative of the results that may be expected for the year ending December 31, 2023. For further information, refer to our consolidated financial statements and footnotes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2022 filed with the Securities and Exchange Commission (“SEC”).

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Management bases its estimates on historical experience and on various assumptions that are believed to be reasonable under the circumstances. Actual results could differ materially from those estimates.

For our foreign subsidiaries, the local currency is the functional currency. Assets and liabilities of our foreign subsidiaries are translated into U.S. dollars using rates in effect at the balance sheet date while revenues and expenses are translated into U.S. dollars using average exchange rates during the period. The cumulative translation adjustment resulting from changes in exchange rates are included in the consolidated balance sheets as a component of accumulated other comprehensive income in total stockholders’ equity (deficit).

Note B - Net Loss Per Share

Basic net loss per common share is calculated by dividing the net loss attributable to common stockholders by the weighted average number of common shares outstanding (including common shares issuable under our Amended and Restated Directors’ Deferred Compensation Plan, or “DDCP”). Diluted loss per common share is calculated by dividing loss attributable to common stockholders by the weighted average number of common shares outstanding (including common shares issuable under our DDCP) plus the dilutive effect of outstanding instruments such as warrants, stock options, non-vested shares and convertible preferred stock. Because we reported a net loss attributable to common stockholders for all periods presented, diluted loss per common share is the same as basic loss per common share, as the effect of utilizing the fully diluted share count would have reduced the net loss per common share. The following securities (listed on an as-if-converted-to-Common-Stock basis) have been excluded from the computation of diluted weighted average shares outstanding as of March 31, 2023 and 2022, as they would be anti-dilutive (in thousands):

Healthcare Royalty Partners

In January 2018, we, through our wholly-owned subsidiary Antigenics, LLC (“Antigenics”), entered into a Royalty Purchase Agreement (the “HCR Royalty Purchase Agreement”) with Healthcare Royalty Partners III, L.P. and certain of its affiliates (collectively, “HCR”). Pursuant to the terms of the HCR Royalty Purchase Agreement, we sold to HCR 100 % of Antigenics’ worldwide rights to receive royalties from GlaxoSmithKline (“GSK”) on sales of GSK’s vaccines containing our QS-21 STIMULON adjuvant. At closing, we received gross proceeds of $ 190.0 million from HCR. Although we sold all of our rights to receive royalties on sales of GSK’s vaccines containing QS-21, as a result of our obligation to HCR, we are required to account for the $190.0 million in proceeds from this transaction as a liability on our condensed consolidated balance sheet that will be recognized into revenue in proportion to the royalty payments from GSK to HCR over the estimated life of the HCR Royalty Purchase Agreement. The liability is classified between the current and non-current portion of liability related to sale of future royalties and milestones in the condensed consolidated balance sheets based on the estimated royalty payments to be received by HCR in the next 12 months from the financial statement reporting date.

During the three months ended March 31, 2023 , we recognized $ 19.1 million of non-cash royalty revenue, and we recorded $ 17.2 million of related non-cash interest expense related to the HCR Royalty Purchase Agreement.

As royalties are remitted to HCR from GSK, the balance of the recorded liability will be effectively repaid over the life of the HCR Royalty Purchase Agreement. To determine the amortization of the recorded liability, we are required to estimate the total amount of future royalty payments to be received by HCR. The sum of these amounts less the $190.0 million proceeds we received will be recorded as interest expense over the life of the HCR Royalty Purchase Agreement. Periodically, we assess the estimated royalty payments to be paid to HCR from GSK, and to the extent the amount or timing of the payments is materially different from our original estimates, we will prospectively adjust the amortization of the liability, and the related recognition of interest expense. During the three months ended March 31, 2023 , our estimate of the effective annual interest rate over the life of the agreement decreased to 26.7 %, which results in a life of contract interest rate of 22.9 %.

Note H - Fair Value Measurements

We measure our contingent purchase price considerations at fair value. The fair values of our contingent purchase price considerations, $ 0.5 million, included in "Other long-term liabilities" in our condensed consolidated balance sheets, are based on significant inputs not observable in the market, which require them to be reported as Level 3 liabilities within the fair value hierarchy. The valuation of these liabilities use assumptions we believe would be made by a market participant and are mainly based on estimates from a Monte Carlo simulation of our share price, as well as other factors impacting the probability of triggering the milestone payments. Share price was evolved using a geometric Brownian motion, calculated daily for the life of the contingent purchase price considerations.

The fair value of our outstanding debt balance at March 31, 2023 and December 31, 2022 was $ 13.7 million and $ 13.2 million, respectively, based on the Level 2 valuation hierarchy of the fair value measurements standard using a present value methodology that was derived by evaluating the nature and terms of each note and considering the prevailing economic and market conditions at the balance sheet date. The principal amount of our outstanding debt balance at March 31, 2023 and December 31, 2022 was $ 14.0 million and $ 13.6 million, respectively.

Note I - Revenue from Contracts with Customers

Gilead Collaboration Agreement

On December 20, 2018, we entered into a series of agreements with Gilead Sciences, Inc. (“Gilead”) focused on the development and commercialization of up to five novel immuno-oncology therapies. Pursuant to the terms of the license agreement, the option and license agreements and the stock purchase agreement we entered into with Gilead (collectively, the “Gilead Collaboration Agreements”), at the closing of the transaction on January 23, 2019, we received an upfront cash payment from Gilead of $ 120.0 million and Gilead made a $ 30.0 million equity investment in Agenus. On November 6, 2020, we received notice from Gilead that it was returning AGEN1423 to us and voluntarily terminating the applicable license agreement. The termination was effective as of February 4, 2021. In the third quarter of 2021 we ceased development of AGEN1223 and in October 2021 the AGEN1223 option and license agreement was formally terminated. The AGEN2373 option and license agreement and the stock purchase agreement remain in full force and effect. We remain eligible to receive a $ 50.0 million exercise fee and, if exercised, up to $ 520.0 million in aggregate potential milestones.

Collaboration Revenue

For the three months ended March 31, 2023 , we recognized approximately $ 2.3 million of research and development revenue based on the partial satisfaction of the over time performance obligations as of quarter end. For the three months ended March 31, 2022, we recognized research and development revenue of $ 5.0 million related to the achievement of a milestone and $ 1.4 million based on the partial satisfaction of the over time performance obligations as of quarter end.

We expect to recognize deferred research and development revenue of $ 9.9 million for the remainder of 2023 related to performance obligations that are unsatisfied or partially unsatisfied as of March 31, 2023.

Contract Balances

Contract assets primarily relate to our rights to consideration for work completed in relation to our research and development services performed but not billed at the reporting date. The contract assets are transferred to receivables when the rights become unconditional. Currently, we do not have any contract assets which have not transferred to a receivable. We had no asset impairment charges related to contract assets in the period. Contract liabilities primarily relate to contracts where we received payments but have not yet satisfied the related performance obligations. The advance consideration received from customers for research and development services or licenses bundled with other promises is a contract liability until the underlying performance obligations are transferred to the customer.

The change in contract liabilities is primarily related to the recognition of $ 2.3 million of revenue related to the Gilead Collaboration Agreements during the three months ended March 31, 2023 . Deferred revenue related to the Gilead Collaboration Agreements of $ 9.9 million as of March 31, 2023 , which was comprised of the $ 142.5 million initial transaction price, less $ 132.6 million of license and collaboration revenue recognized from the effective date of the contract, will be recognized as the combined performance obligation is satisfied.

We also recorded a $ 1.4 million receivable as of March 31, 2023, for research and development and other services provided.

During the three months ended March 31, 2023 , we did not recognize any revenue from amounts included in the contract asset or the contract liability balances from performance obligations satisfied in previous periods. No ne of the costs to obtain or fulfill a contract were capitalized.

Note J - Share-based Compensation Plans

We primarily use the Black-Scholes option pricing model to value stock options granted to employees and non-employees, including stock options granted to members of our Board of Directors. However, the fair value of stock option market-based awards is

Overview

We are a clinical-stage company with a pipeline of therapies designed to activate the body’s immune system to fight cancer and infections, including immune-modulatory antibodies, adoptive cell therapies (through our subsidiary MiNK Therapeutics, Inc. (“MiNK”)) and vaccine adjuvants (through our subsidiary SaponiQx, Inc. (“SaponiQx”)). Our business is designed to drive success in Immuno-oncology (“I-O”) through speed, innovation and effective combination therapies. We believe that combination therapies and a deep understanding of each patient’s cancer will drive substantial expansion of the patient population benefiting from current and potential new I-O therapies. In addition to a diverse pipeline, we have assembled fully integrated end-to-end capabilities including novel target discovery, antibody generation, cell line development and current good manufacturing practice (“cGMP”) clinical manufacturing. We believe that these fully integrated capabilities enable us to produce novel candidates on timelines that are shorter than the industry standard. Leveraging our science and capabilities, we have forged important partnerships to advance our innovation.

We are developing a comprehensive I-O portfolio driven by the following platforms and programs, which we intend to utilize individually and in combination:

our multiple antibody discovery platforms, including our proprietary display technologies, designed to drive the discovery of future antibody candidates;
our antibody candidate programs, including our lead asset, botensilimab, an Fc-enhanced CTLA-4, for which data was presented at the 2023 American Society of Clinical Oncology – Gastrointestinal Cancers Symposium demonstrating in combination with balstilimab (PD-1) significant activity in "cold tumors," such as microsatellite stable colorectal cancer ("MSS CRC");
our saponin-based vaccine adjuvant platform under SaponiQx, principally including our QS-21 STIMULON adjuvant (“QS-21 STIMULON”); and
a pipeline of novel allogeneic invariant natural killer T cell (“iNKT”) therapies to treat cancer and other immune-mediated diseases controlled by MiNK.

We assess development, commercialization and partnering strategies for each of our product candidates periodically based on several factors, including pre-clinical and clinical trial results, competitive positioning and funding requirements and resources. Our lead program, botensilimab (AGEN1181), is advancing in multiple clinical programs which we have designed to support regulatory

16


pathways for accelerated development with botensilimab as a monotherapy and in combination with balstilimab. We initiated worldwide trials for botensilimab in microsatellite stable colorectal cancer, melanoma and pancreatic cancer in 2022.

We have formed collaborations with companies such as Bristol-Myers Squibb Company (“BMS”), Betta Pharmaceuticals Co., Ltd. (“Betta”), Gilead Sciences, Inc. (“Gilead”), Incyte Corporation (“Incyte”) and Merck Sharpe & Dohme (“Merck”). Through these alliances, as well as our own internal programs, we currently have more than a dozen antibody programs in pre-clinical or clinical development.

Pursuant to our collaboration agreement with Incyte, we have exclusively licensed to Incyte monospecific antibodies targeting GITR, OX40, TIM-3 and LAG-3, which Incyte has been advancing in various clinical trials, as well as an additional undisclosed target that Incyte was advancing in preclinical studies. In October 2022, Incyte notified us of their intent to terminate the OX40 program, effective October 2023, and in May 2023, Incyte notified us of their intent to terminate both the GITR program and the undisclosed program, effective May 2024. On termination the rights to the OX40, GITR and undisclosed programs revert back to us. Under the terms of our agreement, Incyte is responsible for all future development expenses for the remaining programs, and we are eligible to receive up to an additional $315.0 million in potential milestone payments plus royalties on any future sales. Pursuant to our collaboration and license agreement with Merck, we exclusively licensed to Merck a monospecific antibody targeting ILT4, which Merck is advancing in a Phase 2 clinical trial. Under the terms of our agreement, Merck is responsible for all future development expenses, and we are eligible to receive up to an additional $85.0 million in potential milestone payments plus royalties on any future sales. In September 2018, we, through our wholly-owned subsidiary, Agenus Royalty Fund, LLC, entered into a royalty purchase agreement (the “XOMA Royalty Purchase Agreement”) with XOMA (US) LLC (“XOMA”). Pursuant to the terms of the XOMA Royalty Purchase Agreement, XOMA purchased 33% of all future royalties and 10% of all future milestone payments that we are entitled to receive from Incyte and Merck, net of certain of our obligations to a third party. After taking into account our obligations under the XOMA Royalty Purchase Agreement, as of March 31, 2023, we remain eligible to receive up to $283.5 million and $76.5 million in potential development, regulatory and commercial milestones from Incyte and Merck, respectively.

In December 2018, we entered into a series of agreements with Gilead to collaborate on the development and commercialization of up to five novel I-O therapies (the “Gilead Collaboration Agreements”). Pursuant to the Gilead Collaboration Agreements, Gilead received worldwide exclusive rights to our bispecific antibody, AGEN1423, as well as the exclusive option to exclusively license AGEN1223, a bispecific antibody, and AGEN2373, a monospecific antibody. All three assets have entered clinical development. In November 2020, Gilead elected to return AGEN1423 to us and to voluntarily terminate the license agreement effective as of February 4, 2021. In the third quarter of 2021, we ceased development of AGEN1223 and in October 2021 the AGEN1223 option and license agreement was formally terminated. The AGEN2373 option agreement remains in place, and we are responsible for developing the program up to the option decision point, at which time Gilead may acquire exclusive rights to the program on option exercise. We have the right to opt-in to share Gilead’s development and commercialization costs in the United States in exchange for a profit (loss) share on a 50:50 basis and revised milestone payments. In March 2022, we received a $5.0 million clinical milestone under the AGEN2373 option agreement. Pursuant to the terms of the AGEN2373 option agreement, we remain eligible to receive a $50.0 million option exercise fee and, if exercised, up to an additional $520.0 million in aggregate milestone payments, as well as royalties on any future sales.

In June 2020, we entered into a license and collaboration agreement (the “Betta License Agreement”) with Betta, pursuant to which we granted Betta an exclusive license to develop, manufacture and commercialize balstilimab and zalifrelimab in Republic of China, Hong Kong, Macau and Taiwan (“Greater China”). Under the terms of the Betta License Agreement, we received $15.0 million upfront and are eligible to receive up to $100.0 million in milestone payments plus royalties on any future sales in Greater China.

In May 2021, we entered into a License, Development and Commercialization Agreement (“BMS License Agreement”) with BMS to collaborate on the development and commercialization of our pre-clinical proprietary anti-TIGIT bispecific antibody program AGEN1777. Under the BMS License Agreement, we granted BMS an exclusive worldwide license under certain of our intellectual property rights to develop, manufacture and commercialize AGEN1777 and its derivatives in all fields; provided, we retained an option to access the licensed antibodies for use in clinical studies in combination with certain of our other pipeline assets subject to certain restrictions. Pursuant to the BMS License Agreement, we received a non-refundable upfront cash payment of $200.0 million in July 2021 and are eligible to receive up to $1.36 billion in aggregate development, regulatory and commercial milestone payments plus tiered royalties. In exchange, BMS is responsible for all of the development, regulatory approval, manufacturing and commercialization costs with respect to products containing AGEN1777. We have the option, but not the obligation, to co-fund a minority of the global development costs of products containing AGEN1777 or its derivatives, in exchange for increased tiered royalties. Finally, we also have the option to co-promote AGEN1777 in the U.S. In October 2021, we announced that the first patient was dosed in the AGEN1777 Phase 1 clinical trial, triggering the achievement of a $20.0 million milestone.

In September 2021, we announced the launch of SaponiQx to spearhead innovation in novel adjuvant discovery and vaccine design, including in relation to our saponin-based adjuvants. We also announced our partnership with Ginkgo Bioworks, Inc. to

17


develop SaponiQx’s novel saponin products from sustainably sourced raw materials, with a goal to meet the current demands placed on the vaccine industry for pandemic vaccines. Our QS-21 STIMULON adjuvant is partnered with GlaxoSmithKline (“GSK”) and is a key component in multiple GSK vaccine programs. These programs are in various stages, with the most advanced being GSK’s approved shingles vaccine, Shingrix, which was approved in the United States by the FDA in October 2017. In January 2018, we entered into a Royalty Purchase Agreement with Healthcare Royalty Partners III, L.P. and certain of its affiliates (together, “HCR”), pursuant to which HCR purchased 100% of our worldwide rights to receive royalties from GSK on GSK’s sales of vaccines containing our QS-21 STIMULON adjuvant. We do not incur clinical development costs for products partnered with GSK. We were also entitled to receive up to $40.35 million in milestone payments from HCR based on sales of GSK’s vaccines as follows: (i) $15.1 million upon reaching $2.0 billion last-twelve-months net sales any time prior to 2024 (the “First HCR Milestone”) and (ii) $25.25 million upon reaching $2.75 billion last-twelve-months net sales any time prior to 2026 (the “Second HCR Milestone”). We received the First HCR Milestone after GSK’s net sales of Shingrix for the twelve months ended December 31, 2019 exceeded $2.0 billion and the Second HCR Milestone after GSK’s net sales of Shingrix for the twelve months ended June 30, 2022 exceeded $2.75 billion.

Our business activities include product research and preclinical and clinical development, intellectual property prosecution, manufacturing, regulatory and clinical affairs, corporate finance and development activities, and support of our collaborations. Our product candidates require successful clinical trials and approvals from regulatory agencies, as well as acceptance in the marketplace. Part of our strategy is to develop and commercialize some of our product candidates by continuing our existing arrangements with academic and corporate collaborators and licensees and by entering into new collaborations.

MiNK is focused on the development of unmodified iNKT cell therapies for the treatment of cancer and other life-threatening immune-mediated diseases. MiNK’s most advanced product candidate, agenT-797, is an off-the-shelf, allogeneic, native iNKT cell therapy. MiNK has commenced and enrolled a Phase 1 clinical trial for the treatment of solid tumors as a monotherapy and in combination with commercially approved checkpoint inhibitors (KEYTRUDA® and OPDIVO®). MiNK is also evaluating agenT-797 as a variant-agnostic therapy for patients with viral acute respiratory distress syndrome and published top-line data from this Phase 1 clinical trial in the fourth quarter of 2021, reporting a 77% survival rate in older, mechanically ventilated patients with COVID-19 respiratory failure. Pursuant to an assignment and license agreement with Agenus, MiNK owns the INKT technology including the rights to develop and expand a proprietary pipeline of engineered CAR-INKTs, TCRs, and INKT bispecific engagers.

Historical Results of Operations

Three months ended March 31, 2023 compared to the three months ended March 31, 2022

Research and development revenue

We recognized research and development revenue of approximately $2.6 million and $6.7 million during the three months ended March 31, 2023 and 2022, respectively. Research and development revenues in the first quarter of 2023 primarily consisted of $2.3 million related to the recognition of deferred revenue earned under our Gilead Collaboration Agreements. Research and development revenues in the first quarter of 2022 primarily consisted of a $5.0 million milestone and $1.4 million related to the recognition of deferred revenue, both earned under our Gilead Collaboration Agreements.

Non-cash royalty revenue related to the sale of future royalties

In January 2018, we sold 100% of our worldwide rights to receive royalties from GSK on sales of GSK’s vaccines containing our QS-21 STIMULON adjuvant to HCR. As described in Note F to our Condensed Consolidated Financial Statements, this transaction has been recorded as a liability that amortizes over the estimated life of our Royalty Purchase Agreement with HCR. As a result of this liability accounting, even though the royalties are remitted directly to HCR, we record these royalties from GSK as revenue. Non-cash royalty revenue related to our agreement with GSK increased $1.5 million, to approximately $19.1 million for the three months ended March 31, 2023, from $17.6 million for the three months ended March 31, 2022, due to increased net sales of GSK’s vaccines containing our QS-21 STIMULON adjuvant.

Research and development expense

Research and development expense includes the costs associated with our internal research and development activities, including compensation and benefits, occupancy costs, manufacturing costs, costs of consultants, and administrative costs. Research and development expense increased 35% to $57.1 million for the three months ended March 31, 2023 from $42.4 million for the three months ended March 31, 2022. Increased expenses in the three months ended March 31, 2023 primarily relate to a $11.4 million increase in third-party services and other expenses, largely due to the timing of expenses related to the advancement of our antibody programs, a $1.4 million increase in personnel related expenses, primarily due to increased headcount, a $1.4 million increase in expenses attributable to the activities of our subsidiaries and a $0.5 million increase in other research and development expenses.

General and administrative expense

General and administrative expense consists primarily of personnel costs, facility expenses, and professional fees. General and administrative expenses decreased 4% to $18.2 million for the three months ended March 31, 2023 from $19.0 million for the three

18


months ended March 31, 2022. Decreased expenses in the three months ended March 31, 2023 primarily relate to a $1.2 million decrease in professional fees, primarily due to reduced consulting and external legal costs. These decreases were partially offset by a $0.5 million increase in other general and administrative expenses.

Contingent purchase price consideration fair value adjustment

Contingent purchase price consideration fair value adjustment represents the change in the fair value of our purchase price considerations, which resulted from changes in our share price and changes in the credit spread since each reporting period end. The fair value of our contingent purchase price considerations is mainly based on estimates from a Monte Carlo simulation of our share price.

Interest expense, net

Interest expense, net increased to approximately $16.6 million for the three months ended March 31, 2023 from $15.2 million for the three months ended March 31, 2022, mainly due to increased non-cash interest recorded in connection with our Royalty Purchase Agreement with HCR partially offset by increased interest income earned on our cash equivalents and short-term investments.

Research and Development Programs

For the three months ended March 31, 2023, our research and development programs consisted largely of our antibody programs as indicated in the following table (in thousands).

Research and development program costs include compensation and other direct costs plus an allocation of indirect costs, based on certain assumptions and our review of the status of each program. Our product candidates are in various stages of development and significant additional expenditures will be required if we start new clinical trials, encounter delays in our programs, apply for regulatory approvals, continue development of our technologies, expand our operations, and/or bring our product candidates to market. The total cost of any particular clinical trial is dependent on a number of factors such as trial design, length of the trial, number of clinical sites, number of patients, and trial sponsorship. The process of obtaining and maintaining regulatory approvals for new therapeutic products is lengthy, expensive, and uncertain. Because of the current stage of our product candidates, among other factors, we are unable to reliably estimate the cost of completing our research and development programs or the timing for bringing such programs to various markets or substantial partnering or out-licensing arrangements, and, therefore, when, if ever, material cash inflows are likely to commence.

Liquidity and Capital Resources

We have incurred annual operating losses since inception, and we had an accumulated deficit of $1.8 billion as of March 31, 2023. We expect to incur significant losses over the next several years as we continue development of our technologies and product candidates, manage our regulatory processes, initiate and continue clinical trials, and prepare for potential commercialization of products. To date, we have financed our operations primarily through corporate partnerships, advance royalty sales and the issuance of equity. From our inception through March 31, 2023, we have raised aggregate net proceeds of approximately $1.8 billion through the sale of common and preferred stock, the exercise of stock options and warrants, proceeds from our Employee Stock Purchase Plan, royalty monetization transactions, and the issuance of convertible and other notes.

We maintain an effective registration statement (the “Registration Statement”), covering common stock, preferred stock, warrants, debt securities and units. The Registration Statement includes prospectuses covering the offer, issuance and sale of up to 200 million shares of our common stock from time to time in “at-the-market offerings” pursuant to an At Market Issuance Sales Agreement (the “Sales Agreement”) with B. Riley Securities, Inc. as our sales agent. We sold approximately 33.8 million and 9.2 million shares of our common stock pursuant to the Sales Agreement during the three months ended March 31, 2023 and the period of

19


April 1, 2023 through May 5, 2023, respectively, for aggregate net proceeds totaling $74.2 million. As of May 5, 2023, approximately 50.0 million shares remained available for sale under the Sales Agreement.

We have funded our operations largely from cash received from partners, royalty financing transactions and equity offerings. We transact at-the-market sales from time to time in order to manage our cash balances to make sure cash balances do not drop below a certain level based on our anticipated uses of cash. We execute at-the-market offerings based on market conditions and our stock price. We do not have in place a program whereby at-the-market offerings are executed automatically based on our trading volume.

As of March 31, 2023, we had debt outstanding of $14.0 million in principal. In November 2022, we amended all of the outstanding 2015 Subordinated Notes, extending the due date by two years to February 2025.

Our cash, cash equivalents and short-term investments at March 31, 2023 were $189.2 million, a decrease of $4.1 million from December 31, 2022. Cash and cash equivalents of our subsidiary, MiNK, at December 31, 2022, were $19.6 million. MiNK cash can only be accessed by Agenus through a declaration of a dividend by the MiNK Board of Directors or through settlement of intercompany balances.

Based on our current plans and projections, we believe our cash resources of $189.2 million as of March 31, 2023, will be sufficient to satisfy our liquidity needs for more than one year from when these financial statements were issued.

Management consistently monitors our liquidity position and has the flexibility to adjust spending as necessary to preserve and extend liquidity. We regularly assess the likelihood of success of our programs, and our funding decisions are based on these evaluations. We are prepared to discontinue funding of any activities that do not impact our core priorities and to restrict capital expenditures and/or reduce the scale of our operations. Potential funding sources may include collaborations, out-licensing and/or partnering opportunities for our portfolio programs and product candidates with multiple parties, milestone payments from our existing partnerships, additional third-party agreements, asset sales, project financing, and/or sales of equity securities.

Our future cash requirements include, but are not limited to, supporting clinical trial and regulatory efforts and continuing our other research and development programs. Since inception, we have entered into various agreements with contract manufacturers, institutions, and clinical research organizations (collectively “third party providers”) to perform pre-clinical activities and to conduct and monitor our clinical studies and trials. Under these agreements, subject to the enrollment of patients and performance by the applicable third-party provider, we have estimated our total payments to be $581.4 million over the term of the related activities. Through March 31, 2023, we have expensed $479.0 million as research and development expenses and $454.2 million has been paid under these agreements. The timing of expense recognition and future payments related to these agreements is subject to the enrollment of patients and performance by the applicable third-party provider. We plan to enter into additional agreements with third party providers and we anticipate significant additional expenditures will be required to initiate and advance our various programs.

Part of our strategy is to develop and commercialize some of our product candidates by continuing our existing collaboration arrangements with academic and collaboration partners and licensees and by entering into new collaborations. As a result of our collaboration agreements, we will not completely control the efforts to attempt to bring those product candidates to market. For example, our collaboration with Incyte for the development, manufacture and commercialization of CPM antibodies against certain targets is managed by a joint steering committee, which is controlled by Incyte.

Net cash used in operating activities for the three months ended March 31, 2023 and 2022 was $58.5 million and $52.4 million, respectively. Our future ability to generate cash from operations will depend on achieving regulatory approval and market acceptance of our product candidates, achieving benchmarks as defined in existing collaboration agreements, and our ability to enter into new collaborations. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Forward Looking Statements” in Part I, Item 2 of this Quarterly Report on Form 10-Q and the risks highlighted in Part I, Item 1A "Risk Factors" of our 2022 Form 10-K.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Our primary market risk exposure is foreign currency exchange rate risk. International revenues and expenses are generally transacted by our foreign subsidiaries and are denominated in local currency. Approximately 4.1% and 1.7% of our cash used in operations for the three months ended March 31, 2023 and the year ended December 31, 2022, respectively, was from our foreign subsidiaries. We are exposed to foreign currency exchange rate fluctuation risk related to our transactions denominated in foreign currencies. We do not currently employ specific strategies, such as the use of derivative instruments or hedging, to manage these exposures. Our currency exposures vary but are primarily concentrated in the British Pound, Euro, and Swiss Franc, in large part due to our subsidiaries, Agenus UK Limited and AgenTus Therapeutics Limited, both with operations in England, AgenTus Therapeutics SA, a company formerly with operations in Belgium, and Agenus Switzerland a company formerly with operations in Switzerland.

20


We had cash, cash equivalents and short-term investments at March 31, 2023 of $189.2 million, which are exposed to the impact of interest rate changes, and our interest income fluctuates as interest rates change. Additionally, in the normal course of business, we are exposed to fluctuations in interest rates as we seek debt financing and invest excess cash. Due to the short-term nature of our investments in money market funds and U.S. Treasury Bills, our carrying value approximates the fair value of these investments at March 31, 2023.

There has been no material change to our interest rate exposure and our approach toward interest rate and foreign currency exchange rate exposures, as described in our Annual Report on Form 10-K for the year ended December 31, 2022.

We invest our cash and cash equivalents in accordance with our investment policy. The primary objectives of our investment policy are to preserve principal, maintain proper liquidity to meet operating needs, and maximize yields. We review our investment policy annually and amend it as deemed necessary. Currently, the investment policy prohibits investing in any structured investment vehicles and asset-backed commercial paper. Although our investments are subject to credit risk, our investment policy specifies credit quality standards for our investments and limits the amount of credit exposure from any single issue, issuer, or type of investment. We do not invest in derivative financial instruments. Accordingly, we do not believe that there is currently any material market risk exposure with respect to derivatives or other financial instruments that would require disclosure under this item.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our Principal Executive Officer and Principal Financial Officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures, as such term is defined under Rule 13a-15(e) and Rule 15d-15(e) promulgated under the Exchange Act. Based on this evaluation, our Principal Executive Officer and our Principal Financial Officer concluded that, as of the end of the period covered by this Quarterly Report on Form 10-Q, our disclosure controls and procedures were effective and were designed to ensure that information we are required to disclose in the reports that we file or submit under the Exchange Act is accumulated and communicated to management, including our Principal Executive Officer and Principal Financial Officer, as appropriate, to allow timely decisions regarding required disclosure, and is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms. It should be noted that any system of controls is designed to provide reasonable, but not absolute, assurances that the system will achieve its stated goals under all reasonably foreseeable circumstances. Our Principal Executive Officer and Principal Financial Officer have each concluded that our disclosure controls and procedures as of the end of the period covered by this report are effective at a level that provides such reasonable assurances.

Changes in Internal Control Over Financial Reporting

There was no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the three months ended March 31, 2023 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
