Herzich Paul 4

What Happened Paul Herzich, Chief Technology Officer of Solid Biosciences (SLDB), reported a sale of 10,905 shares on 2026-02-04. The shares were sold for a weighted average price of $6.44 per share, generating proceeds of approximately $70,249. This was a sale (S) and not a purchase—specifically a sell-to-cover tied to the vesting of previously granted restricted stock units (RSUs).

Key Details

• Transaction date: 2026-02-04; Form 4 filed: 2026-02-06 (timely; within the usual 2-business-day window).
• Price: weighted average $6.44; individual trade prices ranged from $6.28 to $6.60.
• Shares sold: 10,905; proceeds ≈ $70,249.
• Reason: sale executed to cover withholding taxes on vested RSUs pursuant to a durable automatic sell-to-cover instruction adopted by Mr. Herzich on August 16, 2024 (per footnote).
• Disclosure: sale was not a discretionary trade by the insider (sell-to-cover instruction). The filer offers to provide breakdown of number of shares sold at each price within the reported range upon request.
• Shares owned after the transaction: not specified in the provided excerpt of the Form 4.

Context Sell-to-cover transactions occur when newly vested RSU shares are sold to satisfy tax withholding and are generally routine; they do not necessarily signal a change in an insider's view of the company. This filing reflects a tax-withholding sale rather than an open-market, discretionary divestiture.
