Overview

We are a clinical-stage biopharmaceutical company dedicated to bringing a first-in-class pipeline of programmed cellular immunotherapies to patients with cancer and autoimmune disorders. Our development of first-in-class cell therapy product candidates is based on a simple notion: we believe that better cell therapies start with better cells.

To create better cell therapies, we have pioneered a therapeutic approach that we generally refer to as cell programming: we create and engineer human induced pluripotent stem cells (iPSCs) to incorporate novel synthetic controls of cell function; we generate a clonal master iPSC line for use as a renewable source of cell manufacture; and we direct the fate of the clonal master iPSC line to produce our first-in-class cell therapy product candidate. Analogous to master cell lines used to manufacture biopharmaceutical drug products such as monoclonal antibodies, we believe clonal master iPSC lines can be used to mass produce multiplexed-engineered cellular immunotherapies which are well-defined and uniform in composition, can be stored in inventory for off-the-shelf availability, can be combined and administered with other therapies, and can have broader patient reach.

Utilizing this therapeutic approach, we are advancing a cell therapy pipeline comprised of off-the-shelf, multiplexed-engineered, iPSC-derived natural killer (NK) and T-cell product candidates that are selectively designed, incorporate novel synthetic controls of cell function, and are intended to deliver multiple mechanisms of therapeutic importance to patients for the treatment of cancer and autoimmune diseases.

We have entered into a research collaboration and license agreement with the Regents of the University of Minnesota to develop off-the-shelf, engineered NK-cell cancer immunotherapies derived from clonal master iPSC lines. Additionally, we have entered into a research collaboration and license agreement with Memorial Sloan Kettering Cancer Center (MSK) to develop off-the-shelf, engineered T-cell cancer immunotherapies derived from clonal master iPSC lines.

In September 2018, we entered into a collaboration and option agreement (Ono Agreement) with Ono Pharmaceutical Co. Ltd. (Ono) for the joint development and commercialization of off-the-shelf, iPSC-derived CAR T-cell product candidates for the treatment of cancer. In June 2022, we entered into an amendment (Ono Amendment) to the Ono Agreement to expand the collaboration to include the research and development of off-the-shelf, iPSC-derived CAR NK-cell product candidates, and pursuant to the Ono Agreement, Ono agreed to provide novel binding domains targeting a second solid tumor antigen under the collaboration.

In April 2020, we entered into a collaboration and option agreement with Janssen Biotech, Inc. (Janssen), part of the Janssen Pharmaceutical Companies of Johnson & Johnson (Janssen Agreement), for the development and commercialization of off-the-shelf, iPSC-derived CAR NK and CAR T-cell product candidates for the treatment of cancer. Through the period ending December 31, 2022, Janssen had exercised a commercial option for two collaboration candidates: an iPSC-derived, CAR-targeted NK cell product candidate for the treatment of B-cell lymphoma, for which the U.S. Food and Drug Administration (FDA) allowed an Investigational New Drug (IND) application in December 2022; and an iPSC-derived, CAR-targeted NK cell product candidate for the treatment of multiple myeloma, for which the companies were preparing to submit an IND application to the FDA in early 2023. On January 3, 2023, we received notice of termination from Janssen of the Janssen Agreement. The termination of the Janssen Agreement took effect on April 3, 2023, and during the three months ended March 31, 2023, we performed wind down activities, including discontinuing development of all collaboration product candidates, including two product candidates that were expected to enter the clinic in 2023.

In January 2023, we announced the discontinuation of our FT516, FT596, FT538, and FT536 NK cell programs to focus our resources on advancing our most innovative and differentiated programs.



                                       23

--------------------------------------------------------------------------------

We were incorporated in Delaware in 2007, and are headquartered in San Diego, CA. Since our inception in 2007, we have devoted substantially all of our resources to our cell programming approach and the research and development of our product candidates, the creation, licensing and protection of related intellectual property, and the provision of general and administrative support for these activities. To date, we have funded our operations primarily through the public and private sale of common stock, the private placement of preferred stock and convertible notes, commercial bank debt and revenues from collaboration activities and grants.

We have never been profitable and have incurred net losses in each year since inception. Substantially all of our net losses resulted from costs incurred in connection with our research and development programs and from general and administrative costs associated with our operations. We expect to continue to incur operating losses for at least the foreseeable future. Our net losses may fluctuate significantly from quarter to quarter and year to year. We expect our expenses will increase substantially in connection with our ongoing and planned activities as we:

conduct our ongoing and planned clinical trials of our product candidates, which may include higher clinical trial expenses associated with arrangements we may enter into with clinical research organizations (CROs) for the execution and management of certain clinical trials, including trials outside of the United States;

conduct Good Manufacturing Practice (GMP) production, including through the use of contract manufacturing organizations (CMOs) for the conduct of some or all of the activities required for manufacturing our iPSC-derived cell product candidates, process and scale-up development and technology transfer activities for the manufacture of our product candidates, including those undergoing clinical investigation and IND-enabling preclinical development;

procure laboratory equipment, materials and supplies for the manufacture of our product candidates and the conduct of our research activities;

conduct preclinical and clinical research to investigate the therapeutic activity of our product candidates;

continue our research, development and manufacturing activities, including under our sponsored research and collaboration agreement with Ono;

maintain, prosecute, protect, expand and enforce our intellectual property portfolio;

engage with regulatory authorities for the development of, and seek regulatory approvals for, our product candidates;

build out business operations at our corporate headquarters, including internal GMP production capabilities;

continue to implement the corporate restructuring and reduction in force that we announced in January 2023; and

continue operating as a public company and support our operations and develop commercial infrastructure for potential commercialization of our product candidates.

We do not expect to generate any meaningful revenues from product sales, royalties, or sales milestones unless and until we successfully complete development and obtain regulatory approval for one or more of our product candidates, which we expect will take a number of years. If we obtain regulatory approval for any of our product candidates, we expect to incur significant commercialization expenses related to product sales, marketing, manufacturing and distribution. Accordingly, we will seek to fund our operations through public or private equity or debt financings, collaboration arrangements, or other sources. However, we may be unable to raise additional funds or enter into such other arrangements when needed on favorable terms or at all. Our failure to raise capital or enter into such other arrangements when needed would have a negative effect on our financial condition and ability to develop our product candidates.

Financial Operations Overview

We conduct substantially all of our activities through Fate Therapeutics, Inc., a Delaware corporation, at our facilities headquartered in San Diego, California. The results of operations include the operations of the Company and its subsidiaries. To date, the aggregate operations of our subsidiaries have not been significant and all intercompany transactions and balances have been eliminated in consolidation.

Collaboration Revenue

To date, we have not generated any revenues from therapeutic product sales or royalties. Our revenues have been derived from collaboration agreements and government grants.

--------------------------------------------------------------------------------

Agreement with Janssen Biotech, Inc.

On April 2, 2020 (the Janssen Agreement Effective Date), we entered into a Collaboration and Option Agreement (the Janssen Agreement) with Janssen Biotech, Inc. (Janssen), part of the Janssen Pharmaceutical Companies of Johnson & Johnson. Additionally, on the Janssen Agreement Effective Date, we entered into a Stock Purchase Agreement (the Stock Purchase Agreement) with Johnson & Johnson Innovation - JJDC, Inc. (JJDC). Under the terms of the Janssen Agreement and the Stock Purchase Agreement taken together, we received $100.0 million, of which $50.0 million was an upfront cash payment and $50.0 million was in the form of an equity investment by JJDC. Additionally, we are entitled to receive fees for the conduct of all research, preclinical development and IND-enabling activities performed by us under the Janssen Agreement.

We determined the common stock purchase by JJDC represented a premium of $9.93 per share, or $16.0 million in aggregate (the Equity Premium), and the remaining $34.0 million was recorded as issuance of common stock in shareholders' equity.

On January 3, 2023, we received notice of termination from Janssen of the Janssen Agreement. The termination will take effect on April 3, 2023, and during the three months ending March 31, 2023, we performed wind down activities, including discontinuing development of all collaboration product candidates under the Janssen Agreement. We expect to be reimbursed for all wind down activities associated with the termination of the Janssen Agreement in the second quarter of this year. Under the terms of the Janssen Agreement, in connection with the termination, (i) all licenses and other rights granted to either party pursuant to the Janssen Agreement have terminated, subject to limited exceptions set forth in the Janssen Agreement; (ii) both parties have wound down all development, commercialization and manufacturing activities under the Janssen Agreement; (iii) neither party has any right to continue to develop, manufacture or commercialize any collaboration candidate or collaboration product or use the other party's materials; and (iv) neither party is restricted from independently developing, manufacturing, or commercializing any product, including any products directed to the same antigens as those of any collaboration candidate or collaboration product.

During the three months ended March 31, 2023, we recognized $52.3 million of collaboration revenue under the Janssen Agreement, of which $41.2 million was previously deferred. During the three months ended March 31, 2022, we recognized $15.9 million of collaboration revenue under the Janssen Agreement.

Agreement with Ono Pharmaceutical Co., Ltd.

On September 14, 2018, we entered into a Collaboration and Option Agreement (the Ono Agreement) with Ono for the joint development and commercialization of two off-the-shelf iPSC-derived CAR T-cell product candidates (Candidate 1 and Candidate 2). Pursuant to the terms of the Ono Agreement, we received an upfront, non-refundable and non-creditable payment of $10.0 million. Additionally, we are entitled to receive fees for the conduct of research and development under a joint development plan, which fees were estimated to be $20.0 million in aggregate.

We concluded that certain units of account within the Ono Agreement represented a customer relationship and in accordance with ASC 606, we determined that the initial transaction price under the Ono Agreement equals $30.0 million, consisting of the upfront, non-refundable and non-creditable payment of $10.0 million and the aggregate estimated research and development fees of $20.0 million. In addition, we identified our performance obligations under the Ono Agreement, including our grant to Ono of a license to certain of our intellectual property subject to certain conditions, our conduct of research services, and our participation in a joint steering committee. We determined that all performance obligations should be accounted for as one combined performance obligation since no individual performance obligation is distinct, and that the combined performance obligation is transferred over the expected term of the conduct of the research services, which is estimated to be four years.

In December 2020, we entered into a letter agreement with Ono pursuant to which Ono delivered proprietary antigen binding domains targeting an antigen expressed on certain solid tumors for incorporation into Candidate 2 and paid the Company a milestone fee of $10.0 million for further research and development of Candidate 2. In addition, Ono terminated all further research and development with respect to Candidate 1, and we retained all rights to research, develop and commercialize Candidate 1 throughout the world without any obligation to Ono.

In June 2022, we entered into an amendment with Ono to the Ono Agreement (the Ono Amendment). Pursuant to the Ono Amendment, the companies agreed to designate an additional antigen expressed on certain solid tumors for research and preclinical development, and Ono agreed to contribute proprietary antigen binding domains targeting such additional solid tumor antigen (Candidate 3). In addition, for both Candidate 2 and Candidate 3, the companies expanded the scope of the collaboration to include the research and development of iPSC-derived CAR NK cell product candidates (in addition to iPSC-derived CAR T-cell product candidates) targeting the designated solid tumor antigens. Similar to Candidate 2, we granted to Ono, during a specified period of time, a preclinical option to obtain an exclusive license under certain intellectual property rights, subject to payment of an option exercise fee to us by Ono, to develop and commercialize Candidate 3 in all territories of the world, where we retain rights to co-develop and co-commercialize Candidate 3 in the United States and Europe under a joint arrangement with Ono under which we are eligible to share at least 50% of the profits and losses. We maintained worldwide rights of manufacture for Candidate 3. The preclinical option expires upon the earlier of: (a) September 30, 2024, or (b) the achievement of the pre-defined preclinical milestone under the joint development plan for Candidate 3. Subject to payment of an extension fee by Ono, Ono may choose to defer its



                                       25

--------------------------------------------------------------------------------

decision to exercise the preclinical option until no later than June 2026. Under the Ono Amendment, aggregate estimated research and development fees have been increased by approximately $9.3 million, for a total estimated $29.3 million in aggregate research and development fees over the course of the joint development plan.

In November 2022, Ono exercised its preclinical option to Candidate 2, and we exercised our preclinical option to co-develop and co-commercialize (CDCC Option) in the United States and Europe under a joint arrangement with Ono. As a result, we received an option exercise fee of $12.5 million from Ono.

During the three months ended March 31, 2023, we recognized $6.7 million of collaboration revenue and $1.0 million of contra-research and development expense under the Ono Agreement. During the three months ended March 31, 2022, we recognized $2.5 million of collaboration revenue under the Ono Agreement.

Research and Development Expenses

Research and development expenses consist of costs associated with the research, preclinical development, process and scale-up development, manufacture and clinical development of our product candidates, the research and development of our cell programming technology including our iPSC product platform, and the performance of research and development activities under our collaboration agreements. These costs are expensed as incurred and include:

salaries and employee-related costs, including stock-based compensation;

costs incurred under clinical trial agreements with investigative sites;

costs to acquire, develop and manufacture preclinical study and clinical trial materials, including our product candidates;

costs associated with conducting our preclinical, process and scale-up development, manufacturing, clinical and regulatory activities, including fees paid to third-party professional consultants, service providers and suppliers;

costs incurred for our research, development and manufacturing activities, including under our collaboration agreements;

costs for laboratory equipment, materials and supplies for the manufacture of our product candidates and the conduct of our research activities;

costs incurred to license and maintain intellectual property; and

facilities, depreciation and other expenses including allocated expenses for rent and maintenance of facilities.

We plan to increase our current level of research and development expenses for the foreseeable future as we continue the clinical and preclinical development and manufacture of our product candidates, research and develop our iPSC product platform, and perform our obligations under collaboration agreements including under our agreements with Ono, University of Minnesota and MSK. Our current planned research and development activities over the next twelve months consist primarily of the following:

conducting clinical trials of our product candidates, including through the engagement of CROs to manage various aspects of our clinical trials;

conducting GMP production, including through the use of CMOs for the conduct of some or all of the activities required for manufacturing our iPSC-derived cell product candidates, process and scale-up development and technology transfer activities for the manufacture of our product candidates, including those undergoing clinical investigation and IND-enabling preclinical development;

procuring laboratory equipment, materials and supplies for the manufacture of our product candidates and the conduct of our research activities;

conducting preclinical and clinical research to investigate the therapeutic activity of our product candidates; and

conducting research, development and manufacturing activities, including under our sponsored research and collaboration agreement with Ono.



                                       26

--------------------------------------------------------------------------------

Due to the inherently unpredictable nature of preclinical and clinical development and manufacture, and given our novel therapeutic approach and the current stage of development of our product candidates, we cannot determine and are unable to estimate with certainty the timelines we will require and the costs we will incur for the development and manufacture of our product candidates. Clinical and preclinical development and manufacturing timelines and costs, and the potential of development and manufacturing success, can differ materially from expectations. In addition, we cannot forecast which product candidates may be subject to future collaborations, when such arrangements will be secured, if at all, and to what degree such arrangements would affect our development and manufacturing plans and capital requirements. We cannot predict the effects of the impact of global economic and market conditions, the COVID-19 pandemic and the ongoing conflict in Ukraine on our business and operations, and our expenditures may be increased by delays or disruptions due to these or other factors, including as a result of actions we take in the near term to ensure business continuity and protect against possible supply chain shortages.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and employee-related costs, including stock-based compensation, for our employees in executive, operational, finance and human resource functions; professional fees for accounting, legal and tax services; costs for obtaining, prosecuting, maintaining, and enforcing our intellectual property; and other costs and fees, including director and officer insurance premiums, to support our operations as a public company. We anticipate that our general and administrative expenses will increase in the future as we increase our research and development activities, maintain compliance with exchange listing and SEC requirements, protect and enforce our intellectual property, and continue to operate as a public company.

Other Income (Expense)

Other income (expense) consists of changes in the fair value of stock price appreciation milestones associated with the Amended and Restated Exclusive License Agreement dated May 15, 2018 (Amended MSK License) with Memorial Sloan Kettering Cancer Center (MSK), interest income earned on cash and cash equivalents and interest income from investments (including the amortization of discounts and premiums).

California Institute for Regenerative Medicine Award

On April 5, 2018, we executed an award agreement with the California Institute for Regenerative Medicine (CIRM) pursuant to which CIRM awarded us $4.0 million to advance our FT516 product candidate into a first-in-human clinical trial (the Award). In November 2019, we submitted an IND application for FT516 in advanced solid tumors. As of March 31, 2023, we have received aggregate disbursements under the Award in the amount of $4.0 million.

Pursuant to the terms of the Award, we, in our sole discretion, have the option to treat the Award either as a loan or as a grant. In connection with our decision to discontinue our FT516 program during the first quarter of 2023, we reversed the liability associated with the Award, and recorded such amount in other income during the three months ended March 31, 2023.

Critical Accounting Policies and Significant Judgments and Estimates

Our management's discussion and analysis of our financial condition and results of operations are based on our unaudited condensed consolidated financial statements, which have been prepared in accordance with United States generally accepted accounting principles. The preparation of these unaudited condensed consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, and expenses and the disclosure of contingent assets and liabilities in our financial statements. On an ongoing basis, we evaluate our estimates and judgments, including those related to the fair value of the stock price appreciation milestones for the Amended MSK License, contracts containing leases, accrued expenses, stock-based compensation, and the estimated total costs expected to be incurred under our collaboration agreements. We base our estimates on historical experience, known trends and events, financial models, and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

The estimates and judgments involved in our accounting policies as described in Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2022, continue to be our critical accounting policies and there have been no other material changes to our critical accounting policies during the three months ended March 31, 2023.

See Note 1 to the unaudited condensed consolidated financial statements for a summary of critical accounting policies and information related to recent accounting pronouncements.

Results of Operations

Comparison of the Three Months Ended March 31, 2023 and 2022

The following table summarizes the results of our operations for the three months ended March 31, 2023 and 2022 (in thousands):



                                        Three Months Ended March 31,          Increase/
                                          2023                 2022          (Decrease)
Collaboration revenue                $       58,980       $       18,414     $    40,566
Research and development expense             65,629               72,139          (6,510 )
General and administrative expense           21,943               20,742           1,201
Total other income                            9,711                8,777             934



Collaboration Revenue. During the three months ended March 31, 2023 and 2022, we recognized revenue of $59.0 million and $18.4 million, respectively, under our collaboration agreements with Janssen and Ono. The increase in collaboration revenue was attributable to recognition of deferred revenue balances associated to the Janssen contract termination.

Research and development expenses. Research and development expenses were $65.6 million for the three months ended March 31, 2023, compared to $72.1 million for the three months ended March 31, 2022. The decrease in research and development expenses was attributable primarily to the following:

$10.4 million decrease in expenditures for laboratory materials and supplies relating to the manufacture of our product candidates and the conduct of our research activities, including under our collaboration agreements; and

$6.5 million decrease in employee compensation and benefits expense, including $7.6 million decrease in employee stock-based compensation expense.

General and administrative expenses. General and administrative expenses were $21.9 million for the three months ended March 31, 2023, compared to $20.7 million for the three months ended March 31, 2022. The increase in general and administrative expenses was attributable primarily to a $3.4 million increase in patent and legal expenses.

Other income (expense), net. Other income (expense), net was $9.7 million and $8.8 million for the three months ended March 31, 2023 and 2022, respectively. During the three months ended March 31, 2023, we recorded $4.0 million in income attributable to the CIRM Award, and $1.7 million in income attributable to the change in fair value of the stock price appreciation milestones under the Amended MSK License. Other income (expense), net for the three months ended March 31, 2023 also consisted of interest income earned on cash and cash equivalents and interest income from investments (including the amortization of discounts and premiums).

During the three months ended March 31, 2022, we recorded $8.4 million in other expense attributable to the change in fair value of the stock price appreciation milestones under the Amended MSK License. Other income (expense), net for the three months ended March 31, 2022 also consisted of interest income earned on cash and cash equivalents and interest income from investments (including the amortization of discounts and premiums).

Liquidity and Capital Resources

We have incurred losses and negative cash flows from operations since inception. As of March 31, 2023, we had an accumulated deficit of $1.1 billion and we anticipate that we will continue to incur net losses for the foreseeable future.

Operating Activities

During the three months ended March 31, 2023, cash used in operating activities was $28.9 million compared to cash used in operating activities of $64.6 million during the three months ended March 31, 2022. The primary driver of this change in cash used in operating activities was our decrease in net loss.

Agreement with Janssen Biotech, Inc.

On April 2, 2020 (the Janssen Agreement Effective Date), we entered into the Janssen Agreement with Janssen to develop iPSC-derived CAR NK- and CAR T-cell product candidates for the treatment of cancer. Additionally, on the Janssen Agreement Effective Date, we entered into the Stock Purchase Agreement with JJDC. Under the terms of the Janssen Agreement and the Stock Purchase Agreement collectively, we received $100.0 million as of the Janssen Agreement Effective Date, of which $50.0 million was an upfront cash payment and $50.0 million was in the form of an equity investment by JJDC. Of the $50.0 million equity investment, $16.0 million represented a premium over the fair value of our common stock and was classified under operating activities.



                                       28

--------------------------------------------------------------------------------

We were entitled to receive fees for the conduct of all research, preclinical development and IND-enabling activities performed by us under the Janssen Agreement. Additionally, we were eligible to receive (i) with respect to the first Janssen Cancer Target, payments of up to $898.0 million upon the achievement of specified development, regulatory and sales milestones (the Janssen Milestone Payments) for the first Collaboration Candidate, and up to $460.0 million in Janssen Milestone Payments for each additional Collaboration Candidate, directed to the first Janssen Cancer Target; and (ii) with respect to each of the second, third and fourth Janssen Cancer Targets, payments of up to $706.0 million in Janssen Milestone Payments for each of the first Collaboration Candidates, and up to $340.0 million in Janssen Milestone Payments for each additional Collaboration Candidate, directed to the applicable Janssen Cancer Target, where certain Janssen Milestone Payments are subject to reduction in the event we elect to co-commercialize and share equally in the profits and losses in the United States of a respective Collaboration Candidate. We were further eligible to receive double-digit tiered royalties ranging up to the mid-teens on net sales of Collaboration Candidates commercialized by Janssen under the Janssen Agreement, subject to reduction under certain circumstances.

On January 3, 2023, we received notice of termination from Janssen of the Janssen Agreement. The termination will take effect on April 3, 2023, and during the three months ending March 31, 2023, we performed wind down activities with Janssen, including discontinuing development of all collaboration product candidates under the Janssen Agreement. Under the terms of the Janssen Agreement, in connection with the termination, (i) all licenses and other rights granted to either party pursuant to the Janssen Agreement will terminate, subject to limited exceptions set forth in the Janssen Agreement; (ii) both parties will wind down any development, commercialization and manufacturing activities under the Janssen Agreement; (iii) neither party will have any right to continue to develop, manufacture or commercialize any collaboration candidate or collaboration product or use the other party's materials; and (iv) neither party is restricted from independently developing, manufacturing, or commercializing any product, including any products directed to the same antigens as those of any collaboration candidate or collaboration product.

In connection with the Janssen Agreement, we have incurred $17.1 million in sublicense fees to certain of our existing licensors, of which $15.6 million has been paid as of March 31, 2023. The $17.1 million in sublicense consideration represents an asset under ASC 340, Other Assets and Deferred Costs and has been amortized to research and development expense ratably with our revenue recognition under the Janssen Agreement.

Agreement with Ono Pharmaceutical Co., Ltd.

On September 14, 2018, we entered into the Ono Agreement with Ono for the joint development and commercialization of two off-the-shelf, iPSC-derived CAR T-cell product candidates (each a Candidate and collectively the Candidates). Under the terms of the Ono Agreement, Ono paid to us an upfront, non-refundable and non-creditable payment of $10.0 million. Additionally, as consideration for our conduct of research and preclinical development under a joint development plan, Ono pays us annual research and development fees set forth in the annual budget included in the joint development plan, which fees are estimated to be $20.0 million in aggregate over the course of the joint development plan. Further, under the terms of the Ono Agreement, Ono had agreed to pay us up to an additional $40.0 million, subject to the achievement of a preclinical milestone and the exercise by Ono of its options to obtain exclusive licenses to develop and commercialize the Candidates. Such fees are in addition to the upfront payment and research and development fees.

On December 4, 2020, we entered into the Ono Letter Agreement with Ono in connection with the Ono Agreement. Pursuant to the Ono Letter Agreement, Ono delivered to us proprietary antigen binding domains targeting an antigen expressed on certain solid tumors and nominated such antigen binding domains as the Ono Antigen Binding Domain for incorporation into Candidate 2. In connection with such nomination, Ono paid us a milestone fee of $10.0 million in December 2020 for further research and development of Candidate 2 under the Ono Agreement, and Ono continues to maintain its option to Candidate 2 under the Ono Agreement. In addition, the Ono Letter Agreement terminated further development with respect to Candidate 1.

On June 28, 2022, we entered into the Ono Amendment, which expanded the scope of the collaboration to include the research and development of CAR-targeted NK cells, and pursuant to which Ono agreed to contribute novel binding domains targeting a second solid tumor antigen (Candidate 3). Under the Ono Amendment, aggregate estimated research and development fees have been increased by approximately $9.3 million, for a total estimated $29.3 million in aggregate research and development fees over the course of the joint development plan, subject to Ono exercising its option to continue the research term for a candidate targeting the second solid tumor antigen.

Pursuant to the Ono Amendment, we and Ono are jointly conducting research and development activities under a joint development plan, with the goal of advancing Candidate 2 and Candidate 3 to a pre-defined preclinical milestone. We have granted to Ono, during a specified period of time, an option to obtain an exclusive license under certain intellectual property rights to develop and commercialize each remaining candidate in all territories of the world, with us retaining the right to co-develop and co-commercialize in the United States and Europe under a joint arrangement whereby we are eligible to share at least 50% of the profits and losses (the Option).

On November 7, 2022, Ono exercised its option for continued development of Candidate 2 (as defined under the Ono Agreement). We elected our CDCC Option for Candidate 2. As a result, we received an Option Exercise Payment (as defined under the Ono Agreement) of $12.5 million. We determined the exercise represented an option with no material right under the Ono

Agreement. We have completed our performance obligations with respect to the exercise of the option and accordingly, recognized the Option Exercise Payment as revenue for the year ended December 31, 2022.

Subject to Ono's exercise of its options to obtain exclusive licenses to develop and commercialize Candidate 2 or Candidate 3 and to the achievement of certain clinical, regulatory and commercial milestones (the Ono Milestones) with respect to the Candidate in specified territories, we are entitled to receive an aggregate of up to $843.0 million in additional milestone payments for each Candidate, with the applicable milestone payments for the United States and Europe subject to reduction by 50% if we elect to co-develop and co-commercialize the Candidate as described above. As of March 31, 2023, we have not received any milestone payments other than the $10.0 million associated with the Ono Letter Agreement in December 2020 and $12.5 million associated with the option exercise in November 2022. We are also eligible to receive tiered royalties (Royalties) ranging from the mid-single digits to the low-double digits based on annual net sales by Ono for each Candidate in specified territories, with such royalties subject to certain reductions. As of March 31, 2023, no royalties have been paid to us under the Ono Agreement, the Ono Letter Agreement or the Ono Amendment.

As a direct result of our entry into the Ono Agreement, the Ono Letter Agreement and the Ono Amendment, we incurred an aggregate of $7.8 million in sublicense consideration to certain of our existing licensors, all of which has been paid as of March 31, 2023. The $7.8 million in sublicense consideration represents an asset under ASC 340, Other Assets and Deferred Costs and is amortized to research and development expense ratably with our revenue recognition under the Ono Agreement

Memorial Sloan Kettering Cancer Center License Agreement

On May 15, 2018, we entered into the Amended MSK License with MSK. The Amended MSK License amended and restated the Exclusive License Agreement entered into between us and MSK on August 19, 2016, pursuant to which we entered into an exclusive license agreement with MSK for rights relating to compositions and methods covering iPSC-derived cellular immunotherapy, including T-cells and NK-cells derived from iPSCs engineered with CARs.

Pursuant to the Amended MSK License, MSK granted us additional licenses to certain patents and patent applications relating to new CAR constructs and off-the-shelf CAR T-cells, including the use of clustered regularly interspaced short palindromic repeat (CRISPR) and other innovative technologies for their production, in each case to research, develop, and commercialize licensed products in the field of all human therapeutic uses worldwide. We have the right to grant sublicenses to certain licensed rights in accordance with the terms of the Amended MSK License, in which case we are obligated to pay MSK a percentage of certain sublicense income received.

In the event a licensed product achieves a specified clinical milestone, MSK is then eligible to receive certain milestone payments totaling up to $75.0 million based on the price of our common stock, where the amount of such payments owed to MSK is contingent upon certain increases in the price of our common stock following the date of achievement of such clinical milestone. These payments are based on common stock price multiples, with the numerator being the fair value of the ten-trading day trailing average closing price of our common stock and the denominator being the ten-trading day trailing average closing price of our common stock as of the effective date of the Amended MSK License, adjusted for any stock splits, cash dividends, stock dividends, other distributions, combinations, recapitalizations, or similar events. Under the terms of the Amended MSK License, upon a change of control of our company, in certain circumstances, we may be required to pay a portion of these payments to MSK based on the price of our common stock in connection with such change of control.

In July 2021, we achieved a specified clinical milestone for a licensed product under the Amended MSK License and our ten-trading day trailing average common stock price exceeded the first, pre-specified threshold. As a result, we remitted the first milestone payment of $20.0 million to MSK during the year ended December 31, 2021. As of March 31, 2023, we recorded a liability of $2.1 million associated with the remaining stock price appreciation milestones for the Amended MSK License.

Investing Activities

During the three months ended March 31, 2023, investing activities provided cash of $9.3 million compared to cash used by investing activities of $7.0 million during the three months ended March 31, 2022. The change was primarily attributable to a decrease in the purchases of investments of $114.5 million during the three months ended March 31, 2023 compared to the purchase of investments of $132.2 million during the three months ended March 31, 2022. All other investing activities for the periods presented were attributable to the purchase of property and equipment.

Financing Activities

For the three months ended March 31, 2023, financing activities provided cash of $0.2 million, which primarily consisted of the issuance of common stock from equity incentive plans pursuant to the exercise of employee stock options.

--------------------------------------------------------------------------------

For the three months ended March 31, 2022, financing activities provided cash of $2.8 million, which primarily consisted of the issuance of common stock from equity incentive plans pursuant to the exercise of employee stock options.

From our inception through March 31, 2023, we have funded our consolidated operations primarily through the public and private sale of common stock, the issuance of warrants, the private placement of preferred stock and convertible notes, commercial bank debt and revenues from collaboration activities and grants. As of March 31, 2023, we had aggregate cash and cash equivalents and investments of $412.8 million.

Registration Statements on Form S-3

In November 2021, we filed an automatic shelf registration statement (File No. 333-260772), which became effective upon filing. The shelf registration statement allows us to issue certain securities, including shares of our common stock, from time to time. The specific terms of any offering under the automatic shelf registration statement are established at the time of such offering. Additionally, we entered into a sales agreement with Jefferies Group LLC (Jefferies) with respect to an at-the-market offering program, under which we may offer and sell, from time to time at our sole discretion, shares of our common stock having an aggregate offering price of up to $350.0 million through Jefferies as the sales agent, pursuant to this automatic shelf registration statement.

Operating Capital Requirements

We anticipate that we will continue to incur losses for the foreseeable future, and we expect the losses to increase as we continue the research, manufacture and development of, and seek regulatory approvals for, our product candidates and conduct additional research, manufacturing and development activities pursuant to our collaboration agreement with Ono. Our product candidates have not yet achieved regulatory approval and we may not be successful in achieving commercialization of our product candidates.

We believe our existing cash and cash equivalents and investments as of March 31, 2023, will be sufficient to fund our projected operating requirements for at least the next twelve months. However, we are subject to all the risks and uncertainties incident in the research, manufacture and development of therapeutic products, and cell therapy product candidates in particular. For example, the FDA or other regulatory authorities may require us to generate additional data or conduct additional preclinical studies, manufacturing activities, or clinical trials, or may impose other requirements beyond those that we currently anticipate. Additionally, it is possible for a product candidate to show promising results in preclinical studies or in clinical trials, but fail to establish sufficient safety and efficacy data necessary to obtain regulatory approvals. As a result of these and other risks and uncertainties and the probability of success, the duration and the cost of our research, manufacturing and development activities required to advance a product candidate cannot be accurately estimated and are subject to considerable variation. We may encounter difficulties, complications, delays and other unknown factors and unforeseen expenses in the course of our research, manufacturing and development activities, any of which may significantly increase our capital requirements and could adversely affect our liquidity.

We will require additional capital for the research, manufacture and development of our product candidates and to perform our obligations under our collaboration agreements, and we may need to seek additional funds sooner than expected due to any changes in our business, operations, financial condition or prospects, including any impacts of inflation rates and global economic conditions, and the ongoing conflict in Ukraine. We expect to finance our capital requirements in the foreseeable future through the sale of public or private equity or debt securities. However, additional capital may not be available to us on reasonable terms, if at all. If we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may have to significantly delay, scale back or discontinue the research, manufacture or development of one or more of our product candidates. If we do raise additional funds through the issuance of additional equity or debt securities, it could result in dilution to our existing stockholders, increased fixed payment obligations and the existence of securities with rights that may be senior to those of our common stock. Additionally, if we incur indebtedness, we may become subject to financial or other covenants that could adversely restrict, impair or affect our ability to conduct our business, such as requiring us to relinquish rights to certain of our product candidates or technologies or limiting our ability to acquire, sell or license intellectual property rights or incur additional debt. Any of these events could significantly harm our business, operations, financial condition and prospects. In addition, the full impact of rising inflation rates, global political and economic instability, the COVID-19 pandemic, and the ongoing conflict in Ukraine on our business, operations, financial condition and prospects, and on the global economy, are currently unknown and difficult to predict, and these events could materially and adversely affect our ability to raise capital through equity or debt financings in the future.

Our forecast of the period of time through which our existing cash and cash equivalents and investments will be adequate to support our operations is a forward-looking statement and involves significant risks and uncertainties. We have based this forecast on assumptions that may prove to be wrong, and actual results could vary materially from our expectations, which may adversely affect our capital resources and liquidity. We could utilize our available capital resources sooner than we currently expect. The amount and timing of future funding requirements, both near- and long-term, will depend on many factors, including, but not limited to:

the initiation, timing, progress, size, duration, costs and results of our clinical trials and preclinical studies for our product candidates;



                                       31

--------------------------------------------------------------------------------

the number and the nature of product candidates that we pursue;

the time to and cost of establishing internal GMP production capabilities to support the clinical and potential commercial manufacture of our product candidates at our new corporate headquarters;

the cost of GMP production, process and scale-up development and technology transfer activities for the manufacture of our product candidates, including the cost of laboratory equipment, materials and supplies to support these activities;

the time, cost and outcome of seeking and obtaining regulatory approvals;

the extent to which we are required to pay milestone or other payments under our existing in-license agreements and any in-license agreements that we may enter into in the future, and the timing of such payments, including payments owed to MSK in connection with the stock price appreciation milestones;

the extent to which milestones are achieved under our collaboration agreement with Ono, and any other strategic partnership or collaboration agreements that we may enter into in the future, and the time to achievement of such milestones and our receipt of any associated milestone payments;

the cost of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights, including in our ongoing lawsuits against Shoreline Biosciences, Inc. (Shoreline) and Dr. Dan S. Kaufman (Kaufman), and the cost of enforcing any of our other contractual rights;

the cost of our research and development activities, including our need and ability to hire additional employees and procure additional equipment, materials and supplies;

the establishment and continuation of collaborations and strategic alliances;

the timing and terms of future in-licensing and out-licensing transactions; and

the cost of establishing sales, marketing, manufacturing and distribution capabilities for, and the pricing and reimbursement of, any products for which we may receive regulatory approval.

In addition, we are closely monitoring inflation rates and global political and economic conditions, and the ongoing conflict in Ukraine, and evaluating adjustments to our business and operations, which may negatively impact our financial condition and prospects and our operating results. We will continue to assess our operating capital requirements and may make adjustments to our business and operations if circumstances warrant. If we cannot continue or expand our research, manufacturing and development operations, or otherwise capitalize on our business opportunities, because we lack sufficient capital, our business, operations, financial condition and prospects could be materially adversely affected.

Contractual Obligations and Commitments

We lease certain office, laboratory, and manufacturing space under non-cancelable operating leases. In addition to rent, our leases are subject to certain fixed amenities fees. These leases are also subject to additional variable charges for common area maintenance, property taxes, property insurance and other variable costs. See Note 7 of the unaudited condensed consolidated financial statements for additional detail.

We entered into a license agreement with MSK under which we obtained rights relating to compositions and methods covering iPSC-derived cellular immunotherapy, including T-cells and NK-cells derived from iPSCs engineered with CARs. In the event a licensed product achieves a specified clinical milestone, MSK is then eligible to receive certain milestone payments totaling up to $75.0 million based on the price of our common stock, where the amount of such payments owed to MSK are contingent upon certain increases in the price of our common stock following the date of achievement of such clinical milestone. In July 2021, we achieved the specified clinical milestone for a licensed product under the Amended MSK License and our ten-trading day trailing average common stock price exceeded the first, pre-specified threshold. As a result, we remitted payment to MSK for the first milestone payment of $20.0 million. See Note 2 of the unaudited condensed consolidated financial statements for additional detail surrounding our stock price appreciation milestone obligations.

We have no material contractual obligations not fully recorded on our unaudited condensed consolidated balance sheets or fully disclosed in the notes to the financial statements.

Inflation

Inflation has increased during the periods covered by this Quarterly Report, and is expected to continue to increase for the near future. Inflationary factors, such as increases in the prices of material, interest rates and cost of labor may adversely affect our operating results. Although we do not believe that inflation has had a material impact on our financial position or results of operations to date, we may experience some effect in the near future, especially if inflation rates continue to rise.
