Key Details

• Transaction dates and prices: March 10, 2026 — 207,100 shares @ $11.11; 242,945 pre‑funded warrants @ $11.11.
• Aggregate consideration: ~$5.0 million.
• Shares owned after transaction: not specified in the provided filing excerpt.
• Notable footnotes:
  • F1: Acquired from the issuer under a March 9, 2026 Subscription Agreement.
  • F2: The filing notes Sandell is a manager of NEA 17 GP, LLC and disclaims beneficial ownership to the extent he has no pecuniary interest (institutional ownership structure).
  • F3: The pre‑funded warrants are immediately exercisable but include a customary ownership cap (may not be exercised to the extent they would push ownership above 9.99%, adjustable to 19.99% with notice).
• Filing timeliness: Reported on Form 4 filed March 12, 2026 for a March 10 transaction — appears timely (no late‑filing flag in the provided data).

Context

• Pre‑funded warrants function like a short‑term right to obtain common shares; they are typically used to avoid immediate voting/ownership limits and are exercisable into common stock subject to the stated ownership cap.
• The filing indicates institutional/managerial relationships (NEA entities), so this activity reflects an investor/affiliate acquisition rather than a routine employee tax or option exercise sale. As always, purchases are factual signals of buying interest but do not guarantee future company performance.
