Form 4 shows merger cash-out at $14.25 and option cancellation.

The filing records an insider’s equity being converted to cash due to a completed merger. Common shares were exchanged for $14.25 per share, while options were canceled for cash based on the spread between $14.25 and the option exercise price.

Non-derivative positions include direct, ESOP, and 401(k) shares, all reflected as dispositions on 10/31/2025. Derivatives include options with a $7.99 exercise price on 14,000 shares, which were canceled per the merger terms.
