[Form 4] California BanCorp Insider Trading Activity

Rhea-AI Filing Summary

California BanCorp (BCAL) Form 4: EVP & Chief Credit Officer Peter Nutz reported a Code F transaction on 08/02/2025. The company withheld 936 common shares at $14.60 each (≈$13.7k) to satisfy tax obligations arising from a previously vested equity award. Following the withholding, Nutz still beneficially owns 33,693 BCAL shares held directly.

Because Code F represents an issuer-facilitated tax-withholding event rather than an open-market trade, the move is generally considered neutral with limited information content. The officer’s sizable remaining stake indicates continued alignment with shareholder interests.

Positive

• Executive retains 33,693 shares, demonstrating continued equity exposure and alignment with shareholders

Negative

• No open-market buying activity; transaction does not convey bullish conviction

Insights

Financial Analyst

TL;DR: Small, tax-related share disposal; neutral signal.

The 936-share Code F disposition is routine tax withholding tied to equity award vesting, not a discretionary sale. At roughly $14.6 per share, the value is immaterial versus BCAL’s market cap and Nutz retains 33,693 shares—over 97% of his prior position. No change to insider sentiment or fundamental outlook.
