Allovir Inc

1. Nature of the Business

AlloVir, Inc. (“AlloVir” or “the Company”, formerly known as ViraCyte, Inc.) is a cell therapy company developing highly innovative allogeneic T cell therapies to treat and prevent devastating viral diseases. The Company’s innovative and proprietary virus-specific T cell, or VST, therapy platform allows AlloVir to generate off-the-shelf VSTs designed to restore immunity in patients with T cell deficiencies who are at risk from the life-threatening consequences of viral diseases. There is an urgent medical need for therapies to treat a large number of patients suffering from viral diseases who currently have limited or no treatment options. The Company’s platform includes three innovative, allogeneic, off-the-shelf VST therapy candidates targeting 11 different devastating viruses. The Company’s lead product candidate, posoleucel (previously referred to as Viralym-M or ALVR105), is a multi-VST therapy that targets six viruses: adenovirus (“AdV”), BK virus (“BKV”), cytomegalovirus (“CMV”), Epstein-Barr virus (“EBV”), human herpesvirus 6 (“HHV-6”) and JC virus (“JCV”).

In December 2023, the Company announced the discontinuation of three Phase 3 registrational trials of posoleucel following separate, pre-planned Data Safety Monitoring Board (“DSMB”), futility analyses that concluded the studies were unlikely to meet their primary endpoints. Specifically, the Company discontinued a multicenter, randomized, double-blind, placebo-controlled Phase 3 trial comparing posoleucel to placebo for the prevention of infection or disease due to AdV, BKV, CMV, EBV, HHV-6, or JCV in high-risk adult and pediatric patients after undergoing an allogeneic hematopoietic stem cell transplant. The Company also discontinued two multicenter, randomized, double-blind, placebo-controlled Phase 3 trials of posoleucel – one for the treatment of virus-associated hemorrhagic cystitis and the second for the treatment of adenovirus infection – both after allogeneic hematopoietic cell transplant.

In December 2023, the Company also announced that it would review the detailed datasets from those Phase 3 trials and launcha comprehensive review of strategic alternatives focused on maximizing stockholder value, including, but not limited to, a merger, sale, divestiture of assets, licensing, or other strategic transaction. In connection with the evaluation of strategic alternatives and in order to maximize capital preservation, the Company has implemented a plan to reduce our workforce by approximately 95%. This workforce reduction plan was approved in January 2024, and took place primarily during the first quarter of 2024 and was substantially completed by April 15, 2024.

After a comprehensive review of strategic alternatives, on November 7, 2024, the Company entered into an agreement and plan of merger (the “Merger Agreement”) with Kalaris Therapeutics, Inc. ("Kalaris"). Pursuant to the Merger Agreement, and subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, at the effective time of the Merger, Aurora Merger Sub, Inc., a wholly-owned subsidiary of the Company, will merge with and into Kalaris (the “Merger”), with Kalaris continuing as a wholly-owned subsidiary of the Company and the surviving corporation of the Merger.

The Company expects to devote significant time and resources to the completion of the Merger. If the Merger is not completed, the Company will reconsider its strategic alternatives and may pursue one of the following courses of action, which the Company currently believes are the most likely alternatives if the Merger is not completed:

•

Pursue another strategic transaction similar to the Merger. The Company may resume its process of evaluating other candidate companies interested in pursuing a strategic transaction and, if a candidate is identified, focus its attention on negotiating and completing such strategic transaction with such candidate.

•

Continue to operate its business. The Company could elect to continue to operate its business and pursue licensing or partnering transactions. To continue to operate its business, the Company would require a significant amount of time and financial resources, and the Company would be subject to all the risks and uncertainties involved in the development of product candidates. There is no assurance that the Company could raise sufficient capital to support these efforts, that its development efforts would be successful or that it could successfully obtain the regulatory approvals required to market any product candidate it pursued.

•

Dissolve and liquidate its assets. If the Company is unable, or does not believe that it is able, to find a suitable candidate for another strategic transaction, the Company may dissolve and liquidate its assets. In that event, the Company would be required to pay all of its debts and contractual obligations and to set aside certain reserves for commitments and contingent liabilities. If the Company dissolves and liquidates its assets, there can be no assurance as to the amount or timing of available cash that will remain for distribution to the Company’s stockholders after paying the Company’s debts and other obligations and setting aside funds for commitments and contingent liabilities.

The Company’s pipeline includes additional investigational VST therapies that may benefit high-risk individuals. ALVR106 is the Company’s second off-the-shelf, multi-VST product candidate targeting devastating respiratory diseases caused by human metapneumovirus (“hMPV”), influenza, parainfluenza virus (“PIV”) and respiratory syncytial virus (“RSV”). A Phase 1b/2 proof of concept (“POC”) clinical study of ALVR106 has completed enrollment of patients in Part A of the trial. The Company has paused development of ALVR106, including discontinuing the trial pending the outcome of the Company’s review of strategic alternatives. Preclinical and IND-enabling studies of ALVR107 to treat and cure hepatitis B were completed in 2022 to support advancement into a POC study. Clinical development of ALVR107 has been paused pending the outcome of the Company’s review of strategic alternatives.

Going Concern

In accordance with Accounting Standards Update (“ASU”) 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern (Subtopic 205-40), the Company has evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date the condensed consolidated financial statements are issued.

Since its inception and until recently, the Company devoted substantially all of its resources to recruiting personnel, developing its technology platform and advancing its pipeline of product candidates through discovery, preclinical and clinical trials, acquiring and manufacturing clinical trial materials and maintaining and building its intellectual property portfolio. The Company is subject to risks and uncertainties common to early-stage companies in the biotechnology industry, including, but not limited to, success of clinical trials, development by competitors of new technological innovations, dependence on key personnel, protection of proprietary technology, compliance with government regulations and the ability to secure additional capital to fund operations. Should the Company resume development of its product candidates, the product candidates will require significant additional research and development efforts, including preclinical and clinical testing and regulatory approval, prior to commercialization.

Through September 30, 2024, the Company has funded its operations primarily with proceeds received from the sale of common stock, research grants, and from the sale of preferred stock. The Company has incurred recurring losses since its inception, including net losses attributable to common stockholders of $40.5 million and $130.7 million for the nine months ended September 30, 2024 and 2023, respectively. In addition, at September 30, 2024, the Company had an accumulated deficit of $696.7 million. The Company expects to continue to generate operating losses for the foreseeable future.

The Company has incurred and expects to continue to incur costs and expenditures in connection with the process of evaluating strategic alternatives. There can be no assurance, however, that the Company will be able to successfully consummate any particular strategic transaction. The process of evaluating strategic options has been and may continue to be costly, time-consuming and complex and the Company may incur significant costs related to this continued evaluation, such as legal, accounting and advisory fees and expenses and other related charges.

Based on current projections, the Company believes that its $121.9 million of cash, cash equivalents and short-term investments held at September 30, 2024 will be sufficient to fund planned operations for at least twelve months from the date that these condensed consolidated financial statements are available to be issued. However, due to the consideration of certain qualitative factors, including the discontinuation of all clinical trials and research activities, as well as the Company’s workforce reduction plan, management has concluded there is substantial doubt regarding the Company’s ability to continue as a going concern for more than twelve months from the date that the condensed consolidated financial statements are available to be issued. These financial statements do not include any adjustments that might result from the outcome of this uncertainty. Should the Company resume the development of product candidates, it would need to obtain substantial additional funding in connection with continuing operations, particularly as the Company resumes its preclinical activities and clinical trials for its product candidates. There can be no assurance that the Company will be able to obtain sufficient capital to cover its costs on acceptable terms, if at all.

ElevateBio, LLC – Related Party

On September 17, 2018, the Company executed a Series A2 Preferred Stock Purchase Agreement ("Series A2 Agreement") with ElevateBio, LLC ("ElevateBio") and ElevateBio was a purchaser in our registered direct offering in July 2022. ElevateBio, through its diverse platform of technologies to support cell and gene therapy products and expertise, provides drug development and manufacturing services. As a result of ElevateBio’s purchase of our Series A2 Preferred Stock, which converted to common stock upon completion of our IPO, and as a result of ElevateBio’s participation in the July 2022 registered direct offering, ElevateBio acquired an ownership interest in the Company. The Chief Financial Officer of ElevateBio currently serves in a similar management role with AlloVir. In May 2021, Diana M. Brainard, M.D. succeeded David Hallal, ElevateBio’s Chief Executive Officer, as the Company’s Chief Executive Officer. Mr. Hallal currently serves as Executive Chairman of the Company’s board of directors. Vikas Sinha, our President and Chief Financial Officer, also serves as the Chief Financial Officer of ElevateBio. In addition to Mr. Hallal and Mr. Sinha, Morana Jovan-Embiricos, a director of the Company’s board of directors, also serves as a director of the board of directors of ElevateBio.

2. Summary of Significant Accounting Policies

The Company’s significant accounting policies are disclosed in the audited consolidated financial statements for the year ended December 31, 2023, and notes thereto, which are included in the Company’s Annual Report on Form 10-K that was filed with the Securities and Exchange Commission (the “SEC”) on March 15, 2024. Since the date of those financial statements, there have been no material changes to the Company’s significant accounting policies except as described below.

The Company records costs and liabilities associated with exit and disposal activities in accordance with ASC 420, Exit or Disposal Cost Obligations(ASC 420). Such costs are based on estimates of fair value in the period liabilities are incurred. Given the short duration of when the liability is incurred to when it is paid, there is no significant difference between fair value and the amount paid. Costs are expensed at the date the entity notifies the employee, unless the employee must provide future service, in which case the benefits are expensed ratably over the future service period. The Company evaluates and adjusts these costs as appropriate for changes in circumstances as additional information becomes available. Refer to Note 13 for further information regarding restructuring costs.

Interim Financial Information

The accompanying condensed consolidated balance sheet at September 30, 2024, and the condensed consolidated statements of operations and comprehensive loss, statements of changes in stockholders’ equity for the three and nine months ended September 30, 2024 and 2023 and the condensed consolidated statements of cash flows for the nine months ended September 30, 2024 and 2023 are unaudited. The condensed consolidated interim financial statements have been prepared on the same basis as the audited annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments necessary for the fair presentation of the Company’s financial position at September 30, 2024 and the results of its operations for the three and nine months ended September 30, 2024 and 2023 and its cash flows for the nine months ended September 30, 2024 and 2023. The financial data and other information disclosed in these notes related to the three and nine months ended September 30, 2024 and 2023 are also unaudited. The results for the three and nine months ended September 30, 2024 are not necessarily indicative of results to be expected for the year ending December 31, 2024 or for any other subsequent interim period.

Recent Accounting Pronouncements

From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (“FASB”), or other standard setting bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed, the impact of recently issued standards that are not yet effective will not have a material impact on the Company’s condensed consolidated financial statements upon adoption. Under the Jumpstart Our Business Startups Act of 2012, as amended (the “JOBS Act”), the Company meets the definition of an emerging growth company and has elected the extended transition period for complying with certain new or revised accounting standards pursuant to Section 107(b) of the JOBS Act.

Since December 31, 2023, there have been no new accounting pronouncements adopted by the Company or issued by FASB that are applicable to the Company, except as noted below.

Recently Issued Accounting Pronouncements Not Yet Adopted

In November 2023, the FASB issued ASU 2023-07, Segment Reporting(Topic 280): Improvements to Reportable Segment Disclosures, which requires disclosure of incremental segment information on an interim and annual basis. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal periods beginning after December 15, 2024, and requires retrospective application to all prior periods presented in the financial statements. The Company expects to enhance annual segment reporting disclosures based on the new requirements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires public companies, on an annual basis, to provide disclosure of specific categories in the rate reconciliation, as well as disclosure of income taxes paid disaggregated by jurisdiction. This ASU is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The adoption of this standard is not expected to have a material impact on the Company’s condensed consolidated financial statements and related disclosures.

3. Short-Term Investments

Thefollowing tables summarize the amortized cost and estimated fair value of the Company’s U.S. government treasury securities and marketable securities, which are considered to be available-for-sale investments and are included in short-term investments on the consolidated balance sheets:

Certain short-term debt securities with original maturities of less than three months are included in cash and cash equivalents on the consolidated balance sheets and are not included in the tables above. The Company holds debt securities of companies with high credit quality and has determined that there was no material change in the credit risk of any of its debt securities. At September 30, 2024 and December 31, 2023, all investments had contractual maturities within one year.

4. Fair Value Measurements

The following tables present information about the Company’s financial assets and liabilities measured at fair value on a recurring basis:

During the nine months ended September 30, 2024 and the year ended December 31, 2023, there were no transfers between levels. The Company classifies its money market fund and U.S. government treasury securities as Level 1 assets under the fair value hierarchy, as these assets have been valued using quoted market prices in active markets without any valuation adjustment.

Thecarrying amounts of prepaid expenses and other current assets, prepaid expenses to related party, accounts payable, amount due to related party and accrued expenses approximate their fair values due to the short-term nature of these assets and liabilities.

5. Leases

Operating leases

Development and Manufacturing Services Agreement (“DMS Agreement”) with Third-Party Supplier

In October 2022, the Company entered into a Statement of Work (“SOW”) under the DMS Agreement (“2022 SOW under the DMS Agreement”)with a third-party supplier. The 2022 SOW under the DMS Agreement contained an embedded lease for a dedicated manufacturing suite for the manufacture of AlloVir’s products at the facility because the Company directs how and for what purpose the suite is used and obtains substantially all of the economic benefit of the suite. At inception of the lease, it was determined that, in exchange for this dedicated manufacturing suite, AlloVir will pay the supplier a monthly fixed suite utilization fee, fixed batch payments and other related fixed costs, totaling $16.3 million over the 2.25 year lease term ending in December 2024. As part of the arrangement, there were also variable costs for materials, non-fixed batch payments, testing, storage, knowledge and tech transfer and other common area maintenance fees that were not included in the measurement of the lease liability. The lease of the facility was determined to be classified as an operating lease and commenced in October 2022, the point at which the suite was substantially complete and available for use by the Company. Accordingly, at inception, the Company recorded a right-of-use asset and lease liability of $14.7 million.

In December 2023, the Company issued a notice of termination of the DMS Agreement effective June 2024, or 190 days from the third-party supplier’s receipt of the notice. Management concluded that the notice of termination constituted a lease reassessment under ASC 842 as the Company was granted the option of such termination at the onset of the DMS Agreement and it was previously determined to be reasonably certain of not being exercised. As a result, the remaining lease term was shortened and the Company recorded a $4.9 million reduction to the right-of-use asset and lease liability in December 2023.

In February 2024, the Company entered into a new SOW (“2024 SOW under the DMS Agreement”) that terminated the 2022 SOW under the DMS Agreement with a third-party supplier, resulting in a lease remeasurement under ASC 842. The right-of-use asset was previously impaired and thus as a result of the liability remeasurement, the Company recorded a $5.6 million gain to reduce the lease liability in February 2024. As of June 30, 2024, the Company had paid all remaining lease obligations under the DMS Agreement.

Waltham Leases

In September 2021, the Company entered into a lease agreement with BP Bay Colony LLC and a sublease agreement with AMAG Pharmaceuticals Inc. for the lease of property in Waltham, Massachusetts (collectively, the “Waltham leases”). The space identified under the Waltham leases was intended for general office space, research and development, laboratory use, and light manufacturing. The Waltham leases are classified as operating leases and commenced in September 2021. At the inception date, the Company recorded a ROU asset and lease liability of $6.0 million for the lease and a ROU asset and lease liability of $17.3 million for the sublease based on a July 30, 2030 end date for the Waltham leases. As part of the arrangement, there were also variable costs for common area maintenance fees that were not included in the measurement of the lease liability.

In June 2024, the Company entered into a Termination of Sublease Agreement with AMAG Pharmaceuticals Inc. which terminated the sublease agreement effective June 30, 2024. In consideration of the early termination, the Company paid a $5.7 million termination fee. The Company concluded that this early termination constituted a lease modification under ASC 842 as the Company still had access to the premises for a period of time after the execution date of the agreement. As a result of this modification, the Company included the termination fee in the remeasurement of the lease liability and ROU asset, resulting in a $1.8 million gain on lease remeasurement.

In July 2024, the Company entered into a Termination Agreement with BP Bay Colony LLC which terminates with immediate effect, the existing lease. In consideration of the termination, the Company paid a $7.0 million termination fee. As a result of this termination, the Company recorded a $1.5 million gain on lease termination.

As of September 30, 2024, the Waltham leases have terminated and the Company has paid all remaining lease obligations.

Impairment of Lease Right-of-Use Assets

As a result of the December 2023 announcement of the discontinuation of the Company’sthree Phase 3 registrational trials, a comprehensive review of strategic alternatives, and the December 2023 notice of termination of the DMS Agreement, the Company determined that there was a triggering event for impairment. The Company determined that the operating lease right-of-use assets were not recoverable as the carrying value exceeded the anticipated future cash flows on an undiscounted basis. To measure the impairment, the Company determined the fair value of the operating lease right-of-use assets based on estimated subleasing scenarios, which represent the highest and best use of the right-of-use assets. This fair value assessment utilized market participant assumptions, including the anticipated amount and timing of potential sublease payments using current real estate trends and market conditions. As a result, an impairment charge was calculated by reducing the carrying amount of the operating lease right-of-use assets to their estimated fair value, which was determined by discounting the estimated future cash flows by applying a rate that a market participant would require in assuming the risks associated with those cash flows. In December 2023, the Company recorded an impairment loss of $16.6 million to the operating lease right-of-use assets. No impairment losses were recorded duringthe three and nine months ended September 30, 2024 and 2023, respectively.

Total lease costs were$0.0 million and $2.6 million for thethree months ended September 30, 2024 and 2023, respectively, and $0.6 million and $7.7 million for thenine months ended September 30, 2024 and 2023, respectively. Cash paid for operating leases was $7.0 million and $0.8 million for thethree months ended September 30, 2024 and 2023, respectively, and $17.0 million and $3.9 million for the nine months ended September 30, 2024 and 2023, respectively. The Company’s total variable lease costs, such as materials, non-fixed batch payments, testing, storage, knowledge and tech transfer, and other common area maintenance fees, related to the operating leases was $0.0 million and $0.2 million for thethree months ended September 30, 2024 and 2023, respectively, and $0.1 million and $0.9 million for thenine months ended September 30, 2024 and 2023, respectively.

6. Accrued Expenses

Accrued expenses consisted of the following:

Employee compensation and benefits includes$0.1 million of restructuring liability at September 30, 2024 (see Note 13).

7. Stockholder’s Equity

On May 15, 2023, the Company filed a certificate of amendment to its amended and restated certificate of incorporation authorizing the Company to issue up to 300,000,000 shares of common stock at a par value of $0.0001 per share and 10,000,000 shares of preferred stock at a par value of $0.0001 per share. There wereno shares of preferred stock issued or outstanding at September 30, 2024 and December 31, 2023.

On June 21, 2023, the Company entered into an underwriting agreement with J.P. Morgan Securities LLC, Morgan Stanley & Co. LLC and BoFA Securities, Inc., as the representatives of the several underwriters (the “Underwriters”) relating to an underwritten public offering of 20,000,000 shares of its common stock at a public offering price of $3.75 per share, resulting in net proceeds of $70.2 million after deducting underwriting discounts and commissions of $4.5 million and offering costs of $0.3 million. Under the terms of the underwriting agreement, the Company granted the Underwriters an option, exercisable for 30 days, to purchase up to an additional 3,000,000 shares of its common stock at the same price per share as the shares, less underwriting discounts and commissions. On July 21, 2023, the Underwriters option expired.

The Company has reserved shares of common stock for issuance as follows:

8. Stock-Based Compensation

Stock-Based Compensation Expense

Stock-based compensation expense was as follows:

Stock Modification

In connection with the reduction in the Company’s workforce (“RIF”) (see Note 13), the Company accelerated certain unvested stock options and restricted common stock scheduled to vest in the three month period following the employees’ separation date. The Company determined that the acceleration of the unvested units constituted a Type III modification in accordance with ASC 718, resulting in a new measurement of compensation cost. As of September 30, 2024,664,248 units were accelerated. For thenine months ended September 30, 2024, the acceleration resulted in the recognition of $0.1 million of stock-based compensation expense using the reassessed fair value on the modification date and a reversal of $4.0 million in stock-based compensation expense for previously recognized expense using the original grant date fair value, of which $2.4 million was related to research and development expense and $1.6 million was related to general and administrative expense. There wereno units accelerated during thethree months ended September 30, 2024.

2020 Stock Option and Grant Plan

At September 30, 2024, there is an aggregate of 15,091,301 shares reserved for future issuance under the 2020 Plan.

Restricted Common Stock

The following table summarizes restricted common stock activity for thenine months ended September 30, 2024:

At September 30, 2024, there was $7.0 million of unrecognized stock-based compensation expense related to restricted stock, which is expected to be recognized over a weighted average period of 1.60 years. The total fair value of restricted stock vested was $0.9 million and $3.0 million for thenine months ended September 30, 2024 and 2023, respectively.

Stock Options

The following table summarizes stock option activity (in thousands, except share and per share data):

The aggregate intrinsic value of options is calculated as the difference between the exercise price of the stock options and the fair value of the Company’s common stock for those stock options that had exercise prices lower than the fair value of the common stock as of the end of the period.

There wereno options granted during thenine months ended September 30, 2024. The weighted-average grant date fair value of stock options granted during the nine months ended September 30, 2023 was $4.92 per share. At September 30, 2024, there was $8.9 million of unrecognized stock-based compensation expense related to unvested stock options, which is being recognized over a period of 1.52 years.

2020 Employee Stock Purchase Plan

The Company issued 36,337 common shares under the Employee Stock Purchase Plan (the “ESPP”) during thenine months ended September 30, 2024 at an average price per share of $0.58. Cash received from purchases under the ESPP for thenine months ended September 30, 2024 and 2023 were $0.0 million and $0.3 million, respectively. The Company recognized $0.0 and $0.3 million of compensation expense for the ESPP during thenine months ended September 30, 2024 and 2023, respectively.

At September 30, 2024, there was an aggregate of 1,585,257 shares reserved for future issuance under the ESPP.

9. Income Taxes

The Company’s income tax provision is computed based on the federal statutory rate, the average state statutory rates, net of the related federal benefit, and foreign statutory rates. For the three months ended September 30, 2024 and 2023, the Company didnot record income tax expense due to the generation of net operating losses, the benefits of which have been fully reserved.

The Company’s estimate of the realizability of the deferred tax asset is dependent on estimates of projected future levels of taxable income. In consideration of historical losses and in analyzing future taxable income levels, the Company considered all evidence currently available, both positive and negative, and has not recognized deferred tax assets.

10. Net Loss per Share

The following table summarizes the computation of basic and diluted net loss per share attributable to common stockholders of the Company:

Based on the amounts outstanding at September 30, 2024 and 2023, the Company excluded the following potential shares of common stock from the computation of diluted net loss per share attributable to common stockholders for the three and nine months ended September 30, 2024 and 2023, because including them would have had an anti-dilutive effect. Therefore, the weighted-average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same.

11. Commitments and Contingencies

Legal Proceedings

From time to time, in the ordinary course of business, the Company is subject to litigation and regulatory examinations as well as information gathering requests, inquiries and investigations. On January 19, 2024, a purported stockholder of the Company filed a lawsuit, captioned Zerbato v. AlloVir, Inc. et al., No. 1:24-cv-10152 (D. Mass.) (the “Securities Class Action”), in the U.S. District Court for the District of Massachusetts against the Company and two of its officers purportedly on behalf of a putative class of stockholders. On April 16, 2024, the Court appointed stockholders Harry Levin and Julio Maurice Bueno as lead plaintiffs and their counsel as lead counsel in the action. On June 17, 2024, lead plaintiffs filed their amended complaint. In the amended complaint, lead plaintiffs assert claims purportedly on behalf of a putative class of stockholders consisting of persons who purchased or otherwise acquired Company securities between January 11, 2023 and December 21, 2023, inclusive. The amended complaint asserts claims under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and the related regulations, alleging that the defendants made false and misleading statements and omissions to investors relating to the Company’s three Phase 3 studies of posoleucel. The complaint seeks, among other things, damages, prejudgment and post-judgment interest, and attorneys’ fees, expert fees and other costs. Defendants filed their motion to dismiss the amended complaint on August 16, 2024. The lead plaintiffs’ opposition to Defendants’ motion to dismiss is due on November 12, 2024.

On July 3, 2024, a purported stockholder of the Company filed a derivative lawsuit, captioned Steffens v. Brainard et al., No. 1:24-cv-11721 (D. Mass.), in the U.S. District Court for the District of Massachusetts against certain of the Company’s officers and directors and naming the Company as a nominal defendant. The derivative complaint alleges, purportedly on behalf of the Company, violations of Section 10(b) of the Securities Exchange Act of 1934 and Rule 10b-5 thereunder, breach of fiduciary duty, aiding and abetting breach of fiduciary duty, unjust enrichment, and waste of corporate assets against the individual defendants. These claims are based on substantially identical allegations as the complaint in the above-listed Securities Class Action. The lawsuit seeks, among other things, an award of damages and restitution in favor of the Company, certain changes to the Company’s corporate governance, punitive damages, and attorneys’ fees and costs. On October 21, 2024, the court ordered plaintiff to file timely proof of service or show cause why the case should not be dismissed for failure to effect timely service by November 4, 2024.

On October 21, 2024, a purported stockholder of the Company filed a derivative lawsuit, captioned Lister v. Brainard et al., No. 1:24-cv-12658 (D. Mass.), in the U.S. District Court for the District of Massachusetts against certain of the Company’s officers and directors and naming the Company as a nominal defendant. The derivative complaint alleges, purportedly on behalf of the Company, violations of Section 14(a) of the Securities Exchange Act of 1934, breach of fiduciary duties, unjust enrichment, waste of corporate assets, gross mismanagement, and abuse of control against the individual defendants and contribution under Sections 10(b) and 21D of the Securities Exchange Act of 1934 against Ms. Brainard and Mr. Sinha. These claims are based on substantially identical allegations as the complaint in the above-listed Securities Class Action. The lawsuit seeks, among other things, an award of damages and restitution in favor of the Company, certain changes to the Company’s corporate governance, and attorneys’ fees and costs.

The Company intends to vigorously defend against the lawsuits. As the outcome is not presently determinable, any loss is neither probable nor reasonably estimable.

Other Obligations

We may incur potential contingent payments upon our achievement of clinical, regulatory and commercial milestones, as applicable, or we may be required to make royalty payments under license and grant agreements we have entered into with various entities pursuant to which we have in-licensed certain intellectual property. Due to the uncertainty of the achievement and timing of the events requiring payment under these agreements, the amounts to be paid by us are not fixed or determinable at this time (see Note 8 in the Company’s Annual Report on Form 10-K that was filed with the SEC on March 15, 2024).

12. Related Party Transactions
