Insights

Financial Analyst

TL;DR Insider received accelerated PSU shares at merger close; transactions reflect compensation settlement rather than open-market trading.

The reported activity shows accelerated settlement of performance stock units into Issuer Class A common stock at the effective time of the merger on 09/02/2025. The filings identify two PSU grants (01/01/2023 and 01/01/2024) that vested per their performance conditions and were converted into shares, with a portion withheld for taxes. These transactions are compensation-related and not cash purchases or sales, so no immediate proceeds or market liquidity effects are shown. The resignation and end of Section 16 coverage remove ongoing insider reporting obligations for Ms. Lemon, which slightly reduces future visibility into her holdings.

Corporate Governance Expert

TL;DR Transactions are routine merger-driven PSU settlements; resignation ends Section 16 oversight for this reporting person.

The form documents standard governance outcomes in a merger: acceleration of outstanding PSUs under the merger agreement, issuance of shares upon vesting, and tax-withholding via share retention. The filing appropriately discloses the mechanics of conversion and withholding and notes the reporting personeased to be an officer at the merger effective time. From a governance standpoint, the disclosure is complete for these events, and the termination of reporting status is explicitly stated, which is important for investor transparency.

Explanation of Responses:

1. Reflects shares of Issuer Class A common stock received upon vesting of performance stock units ("PSUs"). Pursuant to the Agreement and Plan of Merger, dated as of March 28, 2025, among HomeStreet, Inc., HomeStreet Bank, a subsidiary of HomeStreet, Inc., and Mechanics Bank, at the effective time of the merger on September 2, 2025, each outstanding PSU held by the Reporting Person was accelerated and entitled the Reporting Person to receive shares of Issuer Class A common stock, plus a cash amount for any accrued but unpaid dividends on the PSUs. In the merger, HomeStreet, Inc. was renamed Mechanics Bancorp.

2. Shares of Issuer Class A common stock were issued to the Reporting Person without payment of any consideration in connection with the vesting of a PSU award granted to the Reporting Person on January 1, 2023. The number of shares issued on the vesting of the PSU was determined based on the achievement of certain performance factors set forth in the PSU. The unvested portion of the PSU was cancelled.

Remarks:

The Reporting Person resigned as an officer of HomeStreet, Inc. in accordance with the terms of the Agreement and Plan of Merger, with such resignation effective as of the effective time of the merger on September 2, 2025.
