Recent Accounting Pronouncements Adopted

ASU 2023-07 - Segment Reporting

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). ASU 2023-07 requires disclosure of incremental segment information on an annual and interim basis. The amendments also require companies with a single reportable segment to provide all disclosures required by these amendments and all existing segment disclosures in ASC 280, Segment Reporting. The amendments are effective for

fiscal years beginning after December 15, 2023, and interim periods beginning after December 15, 2024. The Company adopted ASU 2023-07 effective December 31, 2024.

Operating segments are defined as components of an entity for which separate financial information is available and that is regularly reviewed by the Chief Operating Decision Maker (the “CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company's CODM is the chief executive officer.

The Company is in the development stage, has not yet earned revenue from product sales, and has incurred recurring losses and negative cash flows from operations since inception. The Company operates as a single reporting segment, focused on developing a novel class of therapeutic biologics to selectively modulate disease-specific T cells directly within the patient’s body. The CODM manages and allocates resources to the operations of the Company on a total company basis and therefore does not measure separate segment profit or loss. Managing and allocating resources on a total company basis enables the CODM to assess the overall level of resources available and how to best deploy these resources across functions and research and development programs that are in line with the Company’s long-term strategic corporate goals. Consistent with this decision-making process, the CODM uses consolidated financial information for purposes of evaluating performance, forecasting future period financial results, allocating resources and setting incentive targets. Operating expenses are used to monitor budget versus actual results. All the Company’s long-lived assets are held in the United States and all the Company’s revenues since inception have been earned from collaboration agreements as none of the Company's drug product candidates have yet been approved for commercial sale. The resources utilized for any specific purpose may vary significantly and will depend on a number of factors, including, but not limited to, the Company’s research and development activities and programs, clinical testing, regulatory approval, market conditions, and changes in or revisions to the Company’s business strategy and technology development plans.

ASU 2023-09 - Income Taxes

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which focuses on the rate reconciliation and income taxes paid. ASU No. 2023-09 requires a public business entity (PBE) to disclose, on an annual basis, a tabular rate reconciliation using both percentages and currency amounts, broken out into specified categories with certain reconciling items further broken out by nature and jurisdiction to the extent those items exceed a specified threshold. In addition, all entities are required to disclose income taxes paid, net of refunds received disaggregated by federal, state/local, and foreign and by jurisdiction if the amount is at least 5% of total income tax payments, net of refunds received. For PBEs, the new standard is effective for annual periods beginning after December 15, 2024, with early adoption permitted. For entities other than PBEs, the requirements will be effective for annual periods beginning after December 15, 2025. An entity may apply the amendments in this ASU prospectively by providing the revised disclosures for the period ending December 31, 2025 and continuing to provide the pre-ASU disclosures for the prior periods, or may apply the amendments retrospectively by providing the revised disclosures for all period presented. As of December 31, 2025, the Company adopted this new ASU and it only impacts the Company's income tax disclosures with no impact to its operations, cash flows, or financial condition.
