Introductory Note

On August 6, 2021, pursuant to the Agreement to Merge and Plan of Reorganization, dated April 16, 2021, (the “Merger Agreement”), between Bank of Marin Bancorp, a California corporation (“Marin”), and American River Bankshares, a California corporation (the “Company”), the Company merged with and into Marin with Marin continuing as the surviving corporation (the “Merger”).

Item 2.01.

Completion of Acquisition or Disposition of Assets.

As referenced above, on August 6, 2021, pursuant to the Merger Agreement, the Company merged with and into Marin with Marin continuing as the surviving corporation. Immediately after the Merger, American River Bank, a wholly owned bank subsidiary of the Company, merged with and into Bank of Marin, a wholly owned bank subsidiary of Marin, with Bank of Marin continuing as the surviving bank.

Pursuant to the terms and conditions set forth in the Merger Agreement, each outstanding Company common share, no par value per share (“Company Common Shares”) was converted into the right to receive 0.575 (the “Merger Consideration”) of a share of Marin’s common stock (“Marin Common Stock”). For each fractional share that would have otherwise been issued, Marin will pay cash in an amount equal to such fraction multiplied by $33.59.

In addition, each outstanding option to acquire shares of Company Common Shares (a “Company Option”) was cancelled and entitled the holder to receive an amount in cash as determined in accordance with the Merger Agreement, less any applicable taxes required to be withheld with respect to such payment.

Any vesting conditions applicable to outstanding restricted share awards under the Company’s equity incentive plans were automatically accelerated in full and entitled the holder of such awards or units to receive the Merger Consideration, less any applicable taxes required to be withheld with respect to such vesting.

As a result of the Merger, Marin will deliver approximately 3.4 million shares of Marin Common Stock valued at $36.15 per share on August 6, 2021, the last trading day prior to consummation of the Merger. The value of the total merger consideration, including the cash paid for outstanding AMRB stock options, was approximately $125 million.

The foregoing description of the Merger and the Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which was filed as Exhibit 2.1 to the Company’s Current Report on Form 8-K filed on April 19, 2021, which is incorporated herein by reference.

Item 3.01.

Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On August 6, 2021, the Company notified the NASDAQ Stock Market (“NASDAQ”) that trading in the Company Common Shares should be halted prior to market open on August 9, 2021, and that the listing of the Company Common Shares should be removed. The Company requested, and NASDAQ filed, a notification of removal from listing of the Company Common Stock on Form 25 with the Securities and Exchange Commission. The Company intends to file a Form 15 with respect to the Company Common Shares requesting the deregistration of the Company Common Shares under Section 12 of the Exchange Act and the suspension of the Company’s reporting obligations under Sections 13 and 15(d) of the Exchange Act.
