On August 20, 2018, Hanmi Financial Corporation (“Hanmi”) entered into an amendment (“Amendment No. 1”) to the Agreement and Plan of Merger, dated as of May 18, 2018, with SWNB Bancorp, Inc. (the “Merger Agreement,” together with Amendment No. 1, the “Amended Merger Agreement”).

Amendment No. 1 amends the individual election limits for SWNB shareholders. Under the terms of the Amendment No. 1, each SWNB shareholder may elect to receive for each share of SWNB common stock they own either: (i) $5.74 in cash or (ii) 0.1961 shares of Hanmi common stock, provided that, in the aggregate, 70% of the SWNB shares issued and outstanding will be converted into Hanmi common stock and the remaining shares will be converted into cash. Previously, under the terms of the Merger Agreement, each SWNB shareholder may have elected to receive for each share of SWNB common stock they own either: (i) $5.74 in cash or (ii) 0.1961 shares of Hanmi common stock, provided that, in the aggregate, 80% of the SWNB shares issued and outstanding would have been converted into Hanmi common stock and the remaining shares will be converted into cash.

Other than as expressly modified pursuant to Amendment No. 1, the Merger Agreement, which was previously filed as Exhibit 2.1 to the Current Report on Form 8-K filed with the Securities and Exchange Commission by the Company on May 21, 2018, remains in full force and effect as originally executed on May 18, 2018. The foregoing description of Amendment No.1 does not purport to be complete and is subject to, and qualified in its entirety by the full text of Amendment No. 1 attached hereto as Exhibit 2.1 to this Current Report on Form 8-K, which is incorporated herein by reference.

Pursuant to the Merger Agreement, SWNB convened a special meeting of shareholders (the “Special Meeting”) on Thursday, August 16, 2018 at 2:00 p.m., local time, at Southwestern National Bank’s corporate headquarters, 6901 Corporate Drive, Houston, Texas 77036. The Special Meeting was adjourned to allow the shareholders of SWNB additional time to consider the Amendment No. 1. The Special Meeting has been adjourned to August 28, 2018 at 2:00 p.m., local time, at Southwestern National Bank’s corporate headquarters, 6901 Corporate Drive, Houston, Texas 77036, to consider and vote upon the proposals described in the notice of meeting that was sent to each shareholder of record as of the close of business on July 9, 2018. A letter was mailed to SWNB shareholders on or about August 20, 2018 announcing the adjournment of the Special Meeting. A copy of the letter is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

Supplement to the Proxy Statement/Prospectus

This Current Report on Form 8-K (this “Form 8-K”) is being filed to update and supplement the proxy statement/prospectus (the “proxy statement/prospectus”), (1) included in the Registration Statement on Form S-4, File No. 333-225818, filed by Hanmi, with the Securities and Exchange Commission (the “SEC”), and declared effective by the SEC on July 12, 2018, (2) filed by Hanmi with the SEC as a prospectus on July 12, 2018, and (3) mailed by SWNB to its shareholders on or around July 18, 2018. The information contained in this Form 8-K is incorporated by reference into the proxy statement/prospectus. Terms used in this Form 8-K, but not otherwise defined, shall have the meanings ascribed to such terms in the proxy statement/prospectus.

The supplemental information contained in this Form 8-K should be read in conjunction with the proxy statement/prospectus, which should be read in its entirety. To the extent that information in this Form 8-K differs from or updates information contained in the proxy statement/prospectus, the information in this Form 8-K shall supersede or supplement the information in the proxy statement/prospectus. The information contained in this supplement speaks only as of August 20, 2018, unless the information specifically indicates that another date applies.

If you have not already submitted a proxy for use at the SWNB Special Meeting, you are urged to do so promptly. This Form 8-K does not affect the validity of any proxy card or voting instructions that SWNB shareholders may have previously received or delivered following the distribution of the proxy material dated July 12, 2018. No action is required by any SWNB shareholder who has previously delivered a proxy or voting instructions following the distribution of the proxy material dated July 12, 2018 and who does not wish to revoke or change that proxy or voting instructions.

The disclosure in the second paragraph on the cover page of the proxy statement/prospectus is hereby replaced in its entirety with the following:

If the merger is completed, SWNB stockholders will be entitled to elect to receive for each share of SWNB common stock that they own: (1) $5.74 in cash or (2) 0.1961 shares of Hanmi common stock. SWNB stockholders may receive cash and/or Hanmi common stock for their shares of SWNB common stock. However, individual elections will be limited by the requirement that 70% of the shares of SWNB common stock must be exchanged for Hanmi common stock and 30% must be exchanged for cash. Therefore, the amount of Hanmi common stock and/or cash that each SWNB stockholder receives will depend on the elections made by other SWNB stockholders. Based upon the 13,535,036 shares of SWNB common stock outstanding as of July 9, 2018, Hanmi expects to pay approximately $23.7 million in cash and issue approximately 1,857,954 shares of Hanmi common stock upon completion of the merger.

The disclosure in the second full paragraph on page 1, the third full paragraph on page 7 and the second full paragraph on page 49 of the proxy statement/prospectus is amended to replace each reference to “80%” and “20%” with “70%” and “30%,” respectively.

The last two sentences of the second full paragraph on page 8 and the table on page 8 of the proxy statement/prospectus are hereby replaced in their entirety with the following:

The implied value of one share of SWNB common stock is computed by adding the sum of: (1) 0.7 times the price of a share of Hanmi common stock by the 0.1961 exchange ratio and (2) 0.3 times the cash consideration of $5.74. See “Description of the Merger—Consideration to be Received in the Merger.”

The following paragraph is added to the proxy statement/prospectus on page 35, immediately prior to the heading “SWNB’s Reasons for the Merger; Recommendation of SWNB’s Board of Directors.”

On August 20, 2018, the Hanmi board of directors and the SWNB board of directors agreed to approve a change in the mix of the merger consideration so that 70% of the shares of SWNB common stock must be exchanged for Hanmi common stock and 30% must be exchanged for cash.
