initial public offering financial
"in connection with the Issuer's initial public offering"

It matters because it allows the company to raise money from a wide range of investors, helping it grow, while giving early shareholders a way to sell some of their ownership.

FAQ

What stock option grants did Scribe Therapeutics (SCTX) CFO David Parrot receive?

David Parrot received two option grants on July 23, 2026: 109,426 standard options at $15.00 per share and 109,426 performance-based options at $15.00, both expiring July 22, 2036 and tied to continued service and, for the latter, market-based criteria.

How do the new SCTX CFO options vest for David Parrot?

One option grant for 109,426 shares vests monthly over four years, 1/48 each month, starting August 23, 2026, subject to continued service. The 109,426 performance-based options may vest between July 23, 2026 and July 23, 2029 upon meeting market-based performance criteria.

What open-market share purchases were reported for Scribe Therapeutics (SCTX)?

Indirect purchases on July 23, 2026 totaled 2,666 Scribe Therapeutics common shares at $15.00 per share: 1,333 shares held by the CFO’s spouse and 1,333 shares held by a child, both reported as indirect ownership.

What is the prior SCTX option grant disclosed under Rule 16a-2(a)?

An earlier grant of 8,909 options at an exercise price of $19.13 per share, fully vested and expiring March 12, 2036, was reported. It occurred before Scribe Therapeutics registered its equity under Section 12, and is disclosed pursuant to Rule 16a-2(a).

Are the SCTX CFO’s July 23, 2026 transactions under a 10b5-1 trading plan?

The Form 4 indicates the Rule 10b5-1 checkbox is not marked, and the footnotes do not describe any trading plan. The reported July 23, 2026 option grants and common stock purchases are therefore not identified as being made under a Rule 10b5-1 plan.
