Tan Kevin 4

What Happened
Kevin Tan, CFO & Treasurer of Solid Biosciences (SLDB), had 10,625 restricted stock units (RSUs) vest and convert into 10,625 shares on Feb 13, 2026. Following the vesting, he sold 5,404 shares in an open-market sell-to-cover on Feb 18, 2026 at a weighted average price of $5.82, generating proceeds of $31,469. The remaining 5,221 shares (10,625 − 5,404) were retained. The sale was executed under a pre-existing sell-to-cover instruction and was therefore non‑discretionary.

Key Details

• Transaction dates: RSU conversion/vest recorded 2026-02-13; open-market sale 2026-02-18.
• Sale details: 5,404 shares sold at a weighted average price of $5.82 for total proceeds of $31,469; prices in the sale ranged from $5.23 to $6.14 (per filing).
• RSU detail: The RSUs were granted 2025-02-13 and vest 25% annually over four years (footnote). Each RSU equals one share upon settlement.
• Net change: +5,221 shares retained after the sell-to-cover.
• Footnotes: The sale was a sell-to-cover to satisfy tax withholding under a durable automatic sales instruction letter (adopted Aug 15, 2024); the sell was non‑discretionary.
• Timeliness: The Form 4 was filed on 2026-02-18. The Feb 13 vesting/conversion was reported five days later (filed Feb 18), which is later than the typical two-business-day reporting window for Form 4 (so the vesting/conversion appears reported late by one business day).

Context
These entries reflect routine RSU vesting and a sell-to-cover for taxes rather than a discretionary decision to sell shares. For retail investors, such tax-withholding sales are common and do not necessarily indicate insider sentiment about the company. Purchases by insiders tend to be more informative than routine sell-to-cover transactions.
