• Shares owned after transaction: Not specified in this Form 4 (filing reports transactions by entities but does not list aggregate post-transaction beneficial ownership).
• Notable footnotes: Purchases/sales were executed by Samsara BioCapital LP and Samsara Opportunity Fund; Srinivas is a managing member of the general partner entities and disclaims direct beneficial ownership except to pecuniary interest (F2, F3). Weighted-average prices reflect multiple executions (F1, F5, F6).
• Section 16(b): The Sept. 8 sales and purchases were matchable under Section 16(b) for 48,066 and 48,065 shares respectively; Srinivas agreed to disgorge any short-swing profit realized (F4).
• Filing timeliness: Form filed 2026-09-09 covering transactions on Sept. 4 and Sept. 8 — filed promptly (no late-filing flag noted).

Context These transactions were carried out through institutional fund vehicles (Samsara funds) for which Srinivas serves in a managerial role; such filings often reflect fund-level trading rather than direct personal trading. Purchases are generally viewed as a stronger signal than routine sales, and this Form 4 shows substantial net purchases by the funds. The Section 16(b) note means some short-term matched trades will be reconciled via disgorgement rather than retained profit.
