[Form 4] COASTAL FINANCIAL CORP Insider Trading Activity

Rhea-AI Filing Summary

Brian T. Hamilton, President and Director of Coastal Financial Corp (CCB), reported a sale of 1,708 common shares on 09/15/2025 at a reported price of $109.10 per share, reducing his beneficial ownership to 84,701 shares. The Form 4 was signed by an attorney-in-fact on 09/17/2025.

The filing discloses the composition of Mr. Hamilton's equity holdings under the 2018 Omnibus Incentive Plan: 18,605 restricted stock units (RSUs) vesting monthly through April 30, 2028; 23,226 performance-based RSUs eligible to vest monthly beginning October 1, 2024 through April 30, 2028 subject to continuous employment and stock-price conditions; 15,000 performance-based RSUs eligible to vest April 30, 2028 contingent on return-on-equity versus peers; and 669 RSUs vesting in four remaining installments. Each RSU converts to one share upon vesting.

Positive

• Substantial remaining ownership: reporting person retains 84,701 shares after the sale.
• Long-term alignment: large portion of equity consists of RSUs with multi-year vesting, aligning executive incentives with long-term performance.

Negative

• Insider sale: disposition of 1,708 shares at $109.10 reduces immediate insider stake.
• Performance contingencies: 23,226 and 15,000 RSUs are subject to performance and continuous-employment conditions, so vesting is not guaranteed.

Insights

Securities Analyst

TL;DR Insider sale of 1,708 shares reduces holdings but significant equity remains, largely tied up in time- and performance-based RSUs.

The sale on 09/15/2025 of 1,708 shares at $109.10 is a routine disclosure under Section 16 and appears executed by the reporting person rather than an option exercise or derivative transaction. Post-transaction beneficial ownership of 84,701 shares remains meaningful and much of the equity position is subject to multi-year vesting or performance conditions, which aligns executive incentives with longer-term shareholder outcomes. The presence of performance-based RSUs that vest based on stock-price conditions and return-on-equity creates a potential retention and performance link, but also means a portion of future share dilution depends on the company meeting specified metrics.

Corporate Governance Expert

TL;DR Transaction is a routine insider sale; governance notes focus on the structure and vesting of RSUs tied to performance and tenure.

The disclosure details multiple RSU tranches with staggered vesting and performance contingencies through April 30, 2028, indicating a compensation design that combines retention and pay-for-performance elements. The Form 4 shows no derivative transactions and no indication of accelerated vesting or relinquishment of material governance rights. The filing was executed via attorney-in-fact, which is common for administrative filings. Overall, this is a standard executive equity transaction with governance practices visible through vesting and performance conditions.
