This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the Securities Act), and Section 21E of the Securities Exchange Act of 1934, as amended (the Exchange Act). You should not place undue reliance on these statements. We have based these forward-looking statements largely on our current expectations and projections about future events and financial trends affecting the financial condition of our business. Forward-looking statements should not be read as a guarantee of future performance or results and will not necessarily be accurate indications of the times at, or by, which such performance or results will be achieved. Forward-looking statements are based on information available at the time those statements are made and/or management’s good faith belief as of that time with respect to future events, and are subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in or suggested by the forward-looking statements. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth below under Part II, Item 1A, “Risk Factors” in this Quarterly Report. These statements, which represent our current expectations or beliefs concerning various future events, may contain words such as “may,” “will,” “expect,” “anticipate,” “intend,” “plan,” “believe,” “estimate,” the negative of such terms or other words indicating future results.
These forward-looking statements should, therefore, be considered in light of various important factors, including but not limited to, the following:
the effects of inflation on our financial condition, results of operations, cash flows and performance;
our ability to execute on our plans to research, develop and commercialize our product candidates;
the success of our ongoing and planned clinical trials;
the timing of and our ability to obtain and maintain regulatory approvals for our product candidates;
our ability to identify additional products or product candidates with significant commercial potential that are consistent with our business objectives;
our ability to receive research funding and achieve anticipated milestones under our collaborations;
our partners' abilities to advance drug candidates into, and successfully complete, clinical trials;
our ability to attract collaborators with development, regulatory, and commercialization expertise;
the ability of our publicly announced preliminary clinical trial data to support continued clinical development and regulatory approval for specific treatments;
our ability to protect our intellectual property position;
the rate and degree of market acceptance and clinical utility of our products;
costs of compliance and our failure to comply with new and existing governmental regulations;
the capabilities and strategy of our suppliers and vendors including key manufacturers of our clinical drug supplies;
significant competition in our industry;
costs of litigation and the failure to successfully defend lawsuits and other claims against us;
the potential loss or retirement of key members of management;
our failure to successfully execute our growth strategy including any delays in our planned future growth;
our failure to maintain effective internal controls; and
3

our ability to accurately estimate expenses, future revenues, capital requirements and needs for additional financing.
The factors, risks and uncertainties referred to above and others are more fully described under the heading “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2023 and this Quarterly Report on Form 10-Q. Forward-looking statements should be regarded solely as our current plans, estimates and beliefs. We cannot guarantee future results, events, levels of activity, performance, or achievements. We do not undertake and specifically decline any obligation to update, republish or revise forward-looking statements to reflect future events or circumstances or to reflect the occurrences of unanticipated events.

Xencor, Inc.
Notes to Financial Statements
(unaudited)
September 30, 2024
1. Summary of Significant Accounting Policies
Basis of Presentation
The accompanying unaudited consolidated interim financial statements for Xencor, Inc. (the Company, Xencor, we or us) have been prepared in accordance with U.S. generally accepted accounting principles (GAAP) for interim financial information. The consolidated financial statements include all adjustments (consisting only of normal recurring adjustments) that the management of the Company believes are necessary for a fair presentation of the periods presented. The preparation of consolidated interim financial statements requires the use of management’s estimates and assumptions that affect reported amounts of assets and liabilities at the date of the consolidated interim financial statements and the reported revenues and expenditures during the reported periods. These interim financial results are not necessarily indicative of the results expected for the full fiscal year or for any subsequent interim period.
The accompanying unaudited consolidated interim financial statements and related notes should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s 2023 Annual Report on Form 10-K filed with the Securities and Exchange Commission (SEC) on February 29, 2024.
Principles of Consolidation
The accompanying consolidated financial statements include the accounts of Xencor, Inc. and Gale Therapeutics Inc. (Gale), a variable interest entity (VIE) in which we are the primary beneficiary. Since we own less than 100% of Gale, the Company records net loss attributable to non-controlling interests in its consolidated statements of loss equal to the percentage of the economic or ownership interests retained in Gale by the non-controlling party.
In determining whether we are the primary beneficiary of a VIE, we apply a qualitative approach that determines whether we have (1) the power to direct the activities of the VIE that most significantly impact the entity's economic performance and (2) the obligation to absorb losses of, or the right to receive benefits from the VIE that could potentially be significant to the VIE. We continuously assess whether we are the primary beneficiary of Gale as changes to existing relationships or future transactions may result in us consolidating or deconsolidating Gale.
Use of Estimates
The preparation of consolidated interim financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, other comprehensive income (loss) and the related disclosures. On an ongoing basis, management evaluates its estimates, including estimates related to its accrued clinical trial and manufacturing development expenses, stock-based compensation expense, evaluation of intangible assets, investments, leases and other assets for evidence of impairment, fair value measurements, and contingencies. Significant estimates in these consolidated interim financial statements include estimates made for royalty revenue, accrued research and development expenses, stock-based compensation expenses, intangible assets, incremental borrowing rate for right-of-use asset and lease liability, estimated standalone selling price of performance obligations, estimated time for completing delivery of performance obligations under certain arrangements, the likelihood of recognizing variable consideration, the carrying value of equity instruments without a readily determinable fair value, and recoverability of deferred tax assets.
Reclassifications
Certain prior year amounts in the consolidated financial statements and the notes thereto have been reclassified to conform to the current period's presentation. These reclassifications did not affect the prior period's total assets, liabilities, stockholders' equity, net loss or cash flows. During the nine months ended September 30, 2024, we adopted a change in
11

presentation on our consolidated statements of loss to include loss from disposal of fixed assets in operating expenses. The prior period has been revised to reflect this change in the presentation.
Intangible Assets
The Company maintains definite-lived intangible assets related to certain capitalized costs of acquired licenses and third-party costs incurred in establishing and maintaining its intellectual property rights to its platform technologies and development candidates. These assets are amortized over their useful lives, which are estimated to be the remaining patent life or the contractual term of the license. The straight-line method is used to record amortization expense. The Company assesses its intangible assets for impairment if indicators are present or changes in circumstances suggest that impairment may exist. There was no impairment charge recorded for the three and nine months ended September 30, 2024 and 2023.
The Company capitalizes certain in-process intangible assets that are then abandoned when they are no longer pursued or used in current research activities. We abandoned $1.4 million and $2.2 million of in-process intangible assets during the three and nine months ended September 30, 2024, respectively. We abandoned $0.2 million and $0.8 million of in-process intangible assets during the three and nine months ended September 30, 2023, respectively.
Marketable Debt and Equity Securities
The Company has an investment policy that includes guidelines on acceptable investment securities, minimum credit quality, maturity parameters, and concentration and diversification. The investment policy limits the maturity of any individual security to a maximum of 36 months. The average maturity of securities in the portfolio as of September 30, 2024 is less than 12 months. The Company invests its excess cash primarily in marketable debt securities issued by investment grade institutions.
The Company considers its marketable debt securities to be available-for-sale because it is not more likely than not that the Company will be required to sell the securities before recovery of the amortized cost. These assets are carried at fair value and any impairment losses and recoveries related to the underlying issuer’s credit standing are recognized within other income (expense), while non-credit related impairment losses and recoveries are recognized within accumulated other comprehensive income (loss). There were no impairment losses or recoveries recorded for the three and nine months ended September 30, 2024 and 2023. Accrued interest on marketable debt securities is included in the marketable securities’ carrying value. Each reporting period, the Company reviews its portfolio of marketable debt securities, using both quantitative and qualitative factors, to determine if each security’s fair value has declined below its amortized cost basis. During the three and nine months ended September 30, 2024, the Company recorded an unrealized gain of $2.5 million and $0.5 million, respectively, in its portfolio of marketable debt securities. During the three and nine months ended September 30, 2023, the Company recorded a net unrealized gain of $1.2 million and $6.2 million, respectively. The unrealized gain is due to the changing interest rate environment. The net unrealized gain is recorded in other comprehensive income for the three and nine months ended September 30, 2024 and 2023.
The Company receives equity securities in connection with certain licensing transactions with its partners. These investments in equity securities are carried at fair value with changes in fair value recognized each period and reported within other income (expense). For equity securities with a readily determinable fair value, the Company remeasures these equity investments at each reporting period until such time that the investment is sold or disposed. If the Company sells an investment, any realized gain or loss on the sale of the securities will be recognized within other income (expense) in the consolidated statements of loss in the period of sale.
The Company also had an investment in equity securities without a readily determinable fair value, where the Company elected the measurement alternative to record the investment at its initial cost minus impairment, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. There is no impairment charge for the three months ended September 30, 2024. There was an impairment charge of $20.4 million recorded for the nine months ended September 30, 2024 in connection with the valuation of equity securities without a readily determinable fair value. There was no impairment charge recorded for the three and nine months ended September 30, 2023. Following the closing of Zenas' initial public offering on September 16, 2024, the Company no longer holds an investment in equity securities without a readily determinable fair value. See Note 5.

Liability Related to the Sale of Future Revenues
We treat the sale of future Monjuvi royalties as debt, amortized under the effective interest rate method over the estimated life of the Monjuvi Royalty Sale Agreement. See Note 11. The amortization of the liability related to the sale of future Monjuvi royalties is based on our current estimate of future royalty payments. Royalty revenue will be recognized as earned and the payments made will be a reduction of the liability when paid.
Non-cash Interest Expense on the Liability Related to the Sale of Future Royalties
The total expected royalty payments less the net proceeds received are recorded as non-cash interest expense over the life of the liability. Interest is imputed on the unamortized portion using the effective interest method and is recorded based on the timing of the payments received over the term of the Monjuvi Royalty Sale Agreement. The actual interest rate will be affected by the timing of the royalty payments and changes in the forecasted revenue.
Deferred Income Related to the Sale of Future Revenues
We treat the sale of future Ultomiris royalties as deferred income, amortized under the units-of-revenue method by computing a ratio of the proceeds received to the total expected payments over the term of the Ultomiris Royalty Sale Agreement. See Note 11. The amortization of the liability related to the sale of future royalties is based on our current estimate of future royalty payments. Royalty revenue will be recognized as earned and the payments made will be a reduction of the liability when paid.
Recent Accounting Pronouncements
There have been no material changes in recently issued or adopted accounting standards from those disclosed in the Company's 2023 Annual Report on Form 10-K. The Company has reviewed all recently issued accounting pronouncements and does not believe they will have a material impact on our results of operations, financial condition or cash flows.
There have been no other material changes to the significant accounting policies previously disclosed in the Company’s 2023 Annual Report on Form 10-K.
2. Fair Value of Financial Instruments
Financial instruments included in the financial statements include cash and cash equivalents, marketable debt and equity securities, accounts receivable, accounts payable, and accrued expenses. Marketable debt securities, equity securities, and cash equivalents are carried at fair value. The fair value of the other financial instruments closely approximates their fair value due to their short-term maturities.
The Company accounts for recurring and non-recurring fair value measurements in accordance with FASB Accounting Standards Codification (ASC) 820, Fair Value Measurements and Disclosures (ASC 820). ASC 820 defines fair value, establishes a fair value hierarchy for assets and liabilities measured at fair value, and requires expanded disclosure about fair value measurements. The ASC 820 hierarchy ranks the quality of reliable inputs, or assumptions, used in the determination of fair value and requires assets and liabilities carried at fair value to be classified and disclosed in one of the following three categories:
Level 1—Fair value is determined by using unadjusted quoted prices that are available in active markets for identical assets or liabilities.
Level 2—Fair value is determined by using inputs other than Level 1 quoted prices that are directly or indirectly observable. Inputs can include quoted prices for similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in markets that are not active. Related inputs can also include those used in valuation or other pricing models, such as interest rates and yield curves that can be corroborated by observable market data.
Level 3—Fair value is determined by inputs that are unobservable and not corroborated by market data. Use of these inputs involves significant and subjective judgments to be made by the reporting entity – e.g., determining an appropriate discount factor for illiquidity associated with a given security.

Our policy is to record transfers of assets between Level 1 and Level 2 at their fair values as of the end of each reporting period, consistent with the date of the determination of fair value. During the three and nine months ended September 30, 2024 and 2023, there were no transfers between Level 1 and Level 2.
3. Net Loss Per Common Share
Basic net loss per common share is computed by dividing the net loss attributable to Xencor by the weighted-average number of common shares outstanding during the period without consideration of common stock equivalents. Diluted net loss per common share is computed by dividing the net loss attributable to Xencor by the weighted-average number of common stock equivalents outstanding for the period. Potentially dilutive securities consisting of stock issuable pursuant to outstanding options and restricted stock units (RSUs), and stock issuable pursuant to the 2013 Employee Stock Purchase Plan (ESPP) are not included in the per common share calculation in periods when the inclusion of such shares would have an anti-dilutive effect.
Basic and diluted net loss per common share is computed as follows:

For each of the three and nine months ended September 30, 2024 and 2023, all outstanding potentially dilutive securities have been excluded from the calculation of diluted net loss per common share as the effect of including such securities would have been anti-dilutive.
4. Comprehensive Loss
Comprehensive loss is comprised of net loss and other comprehensive income. For each of the three and nine-month periods ended September 30, 2024 and 2023, the only component of other comprehensive income is net unrealized gain on marketable debt securities. There were no material reclassifications out of accumulated other comprehensive income (loss) during each of the three and nine-month periods ended September 30, 2024 and 2023.

The unrealized losses from the available-for-sale securities are due to changes in the interest rate environment and not changes in the credit quality of the underlying securities in the portfolio.
The Company’s equity securities include securities with a readily determinable fair value and securities without a readily determinable fair value. Equity securities with a readily determinable fair value are carried at fair value with changes in fair value recognized each period and reported within other income (expense), net. For equity securities without a readily determinable fair value, the Company elects the measurement alternative to record these investments at their initial cost and evaluates such investments at each reporting period for evidence of impairment, or observable price changes in orderly transactions for the identical or a similar investment of the same issuer.
The Company sold 443,909 shares of common stock of Astria Therapeutics, Inc. (Astria) in the second quarter of 2024, and sold the remaining 253,958 shares of common stock of Astria in July 2024. The Company does not hold any shares of common stock of Astria as of September 30, 2024. The Company recorded realized gains of $0.1 million and $1.3 million for the three and nine months ended September 30, 2024, respectively. The Company held 697,867 shares of common stock as of September 30, 2023, which were classified as equity securities with a readily determinable fair value. The Company recorded unrealized losses of $0.6 million and $4.5 million for the three and nine months ended September 30, 2023, respectively.
The Company currently holds 1,885,533 shares of common stock of INmune Bio, Inc. (INmune). The 1,885,533 shares of INmune common stock are classified as equity securities with a readily determinable fair value. For the three and nine months ended September 30, 2024, the Company recorded unrealized losses of $6.5 million and $11.1 million, respectively. For the three and nine months ended September 30, 2023, the Company recorded an unrealized loss of $4.4 million and an unrealized gain of $0.8 million, respectively.
The Company currently holds 717,144 shares of common stock of Viridian Therapeutics, Inc. (Viridian). The shares of Viridian common stock are classified as equity securities with a readily determinable fair value. The Company recorded unrealized gains of $7.0 million and $0.7 million for the three and nine months ended September 30, 2024, respectively. The Company recorded unrealized losses of $6.1 million and $9.9 million for the three and nine months ended September 30, 2023, respectively.
The Company holds an equity interest in Zenas BioPharma, Inc. (Zenas). The Company’s equity interests previously included preferred stock in Zenas when Zenas was a privately-held company. The preferred shares were received as an upfront payment and a milestone payment for licensing certain clinical and preclinical assets from the Company and did not have a readily determinable fair value. The Company elected the measurement alternative to carry the Zenas equity at cost minus impairment, plus or minus changes resulting from observable price changes in an orderly transaction for the identical or a similar investment of the same issuer. During the six months ended June 30, 2024, the Company recorded $20.4 million of impairment charge due to an impairment analysis using the measurement alternative for the valuation of a security without a readily determinable fair value.
16

On September 16, 2024, following the closing of Zenas' initial public offering, the Company's preferred stock in Zenas was automatically converted to 3,098,380 shares of common stock which were then classified as equity securities with a readily determinable fair value. The Company subsequently discontinued the use of the measurement alternative in valuing its equity interest in Zenas. As a result, the Company recorded an unrealized gain of $8.6 million for each of the three and nine months ended September 30, 2024.
Equity securities with a readily determinable fair value, which are categorized as Level 1 in the fair value hierarchy under ASC 820, and their fair values (in thousands) as of September 30, 2024 and December 31, 2023 are as follows:

6. Stock Based Compensation
In June 2023, our Board of Directors (the Board) and stockholders approved the 2023 Equity Incentive Plan (the 2023 Plan), which became effective as of June 14, 2023, and superseded the 2013 Equity Incentive Plan (the 2013 Plan). No additional awards may be granted under the 2013 Plan.
The 2023 Plan reserve consists of 3,000,000 shares and the remaining available shares from the 2013 Plan as of the effective date of the 2023 Plan. In addition, any shares of common stock covered by awards granted under the 2013 Plan that terminate on or after June 14, 2023 by expiration, forfeiture, cancellation, or other means without the issuance of such shares will be added to the 2023 Plan reserve. The 2023 Plan does not include a provision for an automatic increase in shares, also known as an evergreen provision.
As of September 30, 2024, the total number of shares of common stock available for issuance under the 2023 Plan is 18,617,423, which includes shares of common stock that were available for issuance under the 2013 Plan as of the
17

effective date of the 2023 Plan. As of September 30, 2024, a total of 2,510,949 options have been granted under the 2023 Plan.
In November 2013, the Board and our stockholders approved the ESPP, which became effective as of December 5, 2013. As of September 30, 2024, the total number of shares of common stock available for issuance under the ESPP is 987,344. Unless otherwise determined by the Board, beginning on January 1, 2014, and continuing until January 1, 2023, the total number of shares of common stock available for issuance under the ESPP automatically increased annually on January 1 by the lesser of (i) 1% of the total number of issued and outstanding shares of common stock as of December 31 of the immediately preceding year, or (ii) 621,814 shares of common stock. The automatic increase has expired, and the number of shares of common stock available for issuance under the ESPP was not increased on January 1, 2024. As of September 30, 2024, we have issued a total of 787,474 shares of common stock under the ESPP.
During the nine months ended September 30, 2024, the Company awarded 1,026,220 RSUs under the 2023 Plan to certain employees and non-employee directors. The standard vesting of these awards is generally in three equal annual installments and is contingent on an employee’s continued service to the Company. The fair value of these awards is determined based on the intrinsic value of the stock on the date of grant and will be recognized as stock-based compensation expense over the requisite service period. As of September 30, 2024, a total of 1,112,887 RSUs have been granted under the 2023 Plan.
The Company extended vesting periods and expiration dates of equity awards for employees who retired in April 2024. There was a $3.1 million incremental expense as a result of the extension of the expiration dates, and there was a $1.2 million expense as a result of the extension of the vesting periods.
Total employee, director and non-employee stock-based compensation expense recognized for the three and nine months ended September 30, 2024 and 2023 are as follows (in thousands):

We calculate the intrinsic value as the difference between the exercise price of the options and the closing price of common stock of $20.11 per share as of September 30, 2024.
The weighted-average fair value of options granted during the nine-month periods ended September 30, 2024 and 2023 were $22.21 and $30.07 per share, respectively. There were 2,068,582 options granted during the nine-month period ended September 30, 2023. We estimated the fair value of each equity award, including stock options and shares issued under our ESPP, using the Black-Scholes option-pricing model based on the date of grant of such stock option or ESPP share issuance date, with the following weighted average assumptions for the three and nine months ended September 30, 2024 and 2023:

7. Leases
The Company leases office and laboratory space in Monrovia, California under a lease that expires in December 2025 with an option to renew for an additional five years at then market rates. The Company has assessed that it is unlikely to exercise the option to extend the lease term.
19

In June 2021, the Company entered into an Agreement of Lease (Lease Agreement) for laboratory and office space in Pasadena, California, which will expire in July 2035. The Lease Agreement provides for two separate phases of lease and occupancy. The first phase commenced on August 1, 2022 and provided the Company with an improvement allowance up to $17.0 million. The second phase of the lease agreement will commence no later than September 30, 2026 and includes an additional improvement allowance up to $3.3 million. In August 2022, the Company entered into an amendment pursuant to which the Company received an additional $5.0 million in tenant improvement allowance in exchange for an increase in the rental rate of the phase 1 space. The Company received delivery of the second phase premises on December 1, 2022. The Company placed the new facility into service in February 2023. In January 2024, the Company entered into an amendment, in which the Company was paid $0.7 million of tenant improvement allowance from the second phase for HVAC costs in the first phase.
In August 2023, the Company entered into a Sublease Agreement for office space in San Diego, California. The term of the Sublease Agreement began in September 2023 and ends in December 2027. In connection with the Sublease Agreement, the Company provided a $0.4 million Letter of Credit to the landlord. The Letter of Credit will decline over the term of the lease. The Company also entered into a Cash Collateral Agreement for $0.4 million, which is classified as restricted cash in the Consolidated Balance Sheets.
The Company’s lease agreements do not contain any residual value guarantees or restrictive covenants.

8. Commitments and Contingencies
From time to time, the Company may be subject to various litigation and related matters arising in the ordinary course of business. We are currently a party to an action initiated by Merus N.V. (Merus) in the District of Delaware alleging that our manufacture, use, offer for sale, sale, and/or importation of common light chain antibodies and heterodimeric antibodies infringes certain claims of three Merus patents. Merus filed its complaint against us on August 5, 2024. Merus asserted claims of U.S. Patent Nos. 9,944,695, 9,358,286 and 11,926,859 (collectively, the Asserted Patents). Merus seeks a judgment of patent infringement, an order enjoining us from infringing the Asserted Patents, a damages award (together with interest), a declaration of willful infringement, and a finding that this case is exceptional. On October 10, 2024, we filed a motion to dismiss the Merus complaint with prejudice under Rule 12(b)(6), in which we argued that all of the activities accused of infringement are covered by the 35 U.S.C.§ 271(e)(1) safe harbor. Merus filed its response to our motion on October 31, 2024, and our deadline for replying to the Merus response is November 14, 2024. We believe we have strong defenses to Merus' claims, including defenses of invalidity and/or non-infringement, but there is no guarantee that we will prevail.
The Company does not believe it is currently subject to other matters where there is at least a reasonable possibility that a material loss may be incurred.
The Company is obligated to make future payments to third parties pursuant to certain license agreements, including sublicense fees, royalties, and payments that become due and payable on the achievement of certain development and commercialization milestones. As the amount and timing of sublicense fees and the achievement and timing of these milestones are not probable and estimable, such commitments have not been included on the Company’s balance sheets for the periods ended September 30, 2024 and December 31, 2023. The Company has also entered into agreements with third-party vendors that will require us to make future payments upon the delivery of goods and services in future periods.
9. Collaboration and Licensing Agreements
The following is a summary description of the material collaboration arrangements in the three and nine months ended September 30, 2024 and 2023.
Alexion Pharmaceuticals, Inc.
In January 2013, the Company entered into an Option and License Agreement (the Alexion Agreement) with Alexion Pharmaceuticals, Inc. (Alexion). Under the terms of the Alexion Agreement, the Company granted to Alexion an exclusive research license, with limited sublicensing rights, to make and use the Company’s Xtend technology to evaluate and advance compounds. Alexion exercised its rights to one target program, ALXN1210, which is now marketed as Ultomiris®.
The Company is entitled to receive royalties based on a percentage of net sales of Ultomiris sold by Alexion, its affiliates or its sublicensees, which percentage is in the low single digits. Alexion’s royalty obligations continue on a product-by-product and country-by-country basis until the expiration of the last-to-expire valid claim in a licensed patent covering the applicable product in such country.
On November 3, 2023, the Company entered into the Ultomiris Royalty Sale Agreement with OMERS, in which OMERS acquired the rights to certain royalties associated with the existing license relating to Ultomiris in exchange for cash consideration. For the nine months ended September 30, 2024, Company earned and recognized $24.9 million in non-cash royalty revenue under the Ultomiris Royalty Sale Agreement.
The Company recognized $8.6 million and $24.9 million of non-cash royalty revenue during the three and nine months ended September 30, 2024, respectively, and $11.8 million and $33.4 million of royalty revenue under this arrangement for the three and nine months ended September 30, 2023, respectively. As of September 30, 2024, there is no receivable and no deferred revenue related to this agreement.
21

Genentech, Inc., and F. Hoffmann-La Roche Ltd
In February 2019, the Company entered into a collaboration and license agreement (the Genentech Agreement) with Genentech, Inc. and F. Hoffmann-La Roche Ltd (collectively, Genentech) for the development and commercialization of novel IL-15 collaboration products (Collaboration Products), including efbalropendekin alfa (also named XmAb306 and RG6323), the Company’s IL-15/IL15Rα-Fc candidate.
Under the terms of the Genentech Agreement, Genentech received an exclusive worldwide license to XmAb306, and we shared in 45% of development and commercialization costs of Collaboration Products. We were also eligible to share in 45% of net profits and losses from the sale of approved products. However, in the fourth quarter of 2023, we agreed with Genentech to convert our current development cost and profit-sharing arrangement into a royalty and milestone payment-based arrangement. Pursuant to the terms of the amended agreement with Genentech, effective June 1, 2024, Genentech assumed sole responsibility over all clinical, regulatory and commercial activities. We are eligible to receive up to $600.0 million in milestones, including $115.0 million in development milestones, $185.0 million in regulatory milestones and $300.0 million in sales-based milestones and tiered royalties ranging from low double-digit to mid-teen percentages.
The Company did not recognize revenue related to the Genentech Agreement for the three and nine months ended September 30, 2024 or 2023. As of September 30, 2024, there is a $7.6 million payable related to cost-sharing development activities during the first half of 2024 for development studies being conducted under the Genentech Agreement. There is no deferred revenue as of September 30, 2024 related to this agreement.
Gilead Sciences, Inc.
