Septerna CMO Kim Jae Receives 125,000-Share Award
What Happened
- Kim Jae, Chief Medical Officer of Septerna, Inc. (SEPN), was granted 125,000 shares as an equity award (reported as a derivative acquisition) on 2026-02-06. The reported acquisition price is $0.00 (no cash paid at grant).
Key Details
- Transaction date: 2026-02-06; Form 4 filed: 2026-02-10 (appears timely under the 2-business-day rule).
- Transaction type/code: Award/Grant (A); reported as a derivative instrument at $0.00.
- Vesting: Footnote states 2/48 of the shares vest on March 1, 2026, with the remaining shares vesting in 46 substantially equal monthly installments thereafter (total 48-month schedule), subject to continued service.
- Shares owned after transaction: not specified in the provided filing excerpt.
- Filing remark: Exhibit 24.2 — Substitute Power of Attorney was attached.
Context
- This was a compensation equity award (not an open-market purchase or sale). The award vests over time, so any actual transfer of shares to the insider depends on future vesting and continued service. Because the grant price is $0.00 and the instrument is recorded as a derivative award, it likely represents company compensation rather than a cash purchase.
