CFSB insider filing shows $14.25 cash merger and option cancellation

Rhea-AI Filing Summary

CFSB Bancorp (CFSB) insider filing tied to merger completion. A company officer (VP-Information Systems) reported transactions on 10/31/2025 reflecting the closing of a merger in which each share of CFSB common stock was converted into the right to receive cash of $14.25 per share.

The filing notes that all unvested restricted stock vested at closing and was treated as outstanding for the cash consideration. Outstanding stock options were cancelled at closing for cash equal to their intrinsic value. One option grant with a $7.99 exercise price covering 14,000 shares was reported as cancelled for cash per the merger terms.

The table lists dispositions across direct holdings and certain indirect accounts (including ESOP, 401(k), spouse, and child) as merger-related conversions to cash. These entries reflect the mechanical effects of the merger consideration rather than open-market transactions.

Form 4 shows merger-driven cash-out at $14.25; options cashed for intrinsic value.

The report documents the mechanical effects of a change-of-control. Common shares were converted into a cash right of $14.25 per share at closing, while unvested restricted stock vested and shared in the same cash treatment. This is a standard outcome when merger consideration is all cash.

For options, the filing states cancellation for cash equal to intrinsic value. One option grant with a $7.99 exercise price over 14,000 underlying shares was handled under this formula. No ongoing equity overhang remains from these awards after cancellation.

Because this is an administrative reflection of a completed merger, the signal is neutral for standalone performance analysis. Any valuation impact was determined by the merger terms as of 10/31/2025.
