[Form 4] Scholar Rock Holding Corporation Insider Trading Activity

Rhea-AI Filing Summary

American Outdoor Brands, Inc. (AOUT) – Form 4 insider filing: President & CEO Brian Daniel Murphy reported several equity transactions dated 07/08/2025.

• Performance-right exercise (Code M): 82,150 common shares acquired at $0 cost stemming from a prior performance-based award tied to stock-price targets. Post-exercise common-share holding rose to 330,047.
• Tax-withholding sale (Code F): 36,187 shares sold at $10.17 per share to cover withholding obligations related to the vesting event; holding declined to 293,860.
• Restricted-stock unit grant (Code A): 48,860 RSUs awarded at no cost. They vest in three equal installments on 7 Jul 2026, 1 May 2027, and 1 May 2028. Common-share ownership after the grant is 342,720 shares.
• New performance-rights grant: 97,718 performance rights (maximum payout = 2× target) awarded, vesting on 7 Aug 2028 subject to cumulative adjusted EBITDA and average ROIC hurdles. Current derivative holding: 97,718 rights.

The combined activity results in a net increase of 94,823 common shares compared with the pre-transaction balance of roughly 247,897 shares. All transactions were executed under direct ownership; no indirect holdings were reported.

Investment view: The filing reflects routine equity-compensation events rather than open-market buying or selling. While the CEO’s net share position rose, the majority of shares came from vesting awards, and the sale was solely for tax purposes. The new performance-based grant aligns future compensation with operating metrics, but no immediate cash flow impact to AOUT is implied.

Positive

• Net increase of 94,823 common shares in the CEO’s direct ownership, marginally aligning executive interests with shareholders
• Performance-based grant of 97,718 rights tied to EBITDA and ROIC establishes longer-term value-creation incentives

Negative

• 36,187 shares sold at $10.17 to cover withholding slightly increases public float
• Potential future dilution from 97,718 new performance rights and 48,860 RSUs upon vesting

Insights

Equity Compensation Analyst

TL;DR: Routine vesting and new awards; CEO’s net stake up 95k shares, no open-market purchase, impact modest.

The Form 4 discloses standard executive-compensation mechanics. An 82,150-share performance award vested after price hurdles were met, increasing Brian Murphy’s direct holdings. The simultaneous sale of 36,187 shares at $10.17 merely settled payroll taxes, a common procedure that avoids out-of-pocket cash. A 48,860-share RSU grant and 97,718 new performance rights were issued, extending incentive alignment through FY2028 with metrics tied to adjusted EBITDA and ROIC. Because there is no discretionary open-market buying or large liquidity sale, the filing is neutral from an ownership-signal perspective. Dilution effects are immaterial relative to AOUT’s ~14 million share count, and the awards were previously expensed under ASC 718. Overall, the disclosure is not expected to move the stock.
