### HOUSEHOLDING OF PROXY MATERIALS
SEC rules permit HomeStreet and intermediaries, such as brokers, to satisfy the delivery requirements for proxy materials by delivering a single set of proxy materials to an address shared by two or more of HomeStreet shareholders, unless contrary instructions have been received in advance according to certain procedures. In cases of such contrary instructions, each shareholder continues to receive a separate notice of the meeting and proxy card.

Certain brokerage firms may have instituted householding for beneficial owners of HomeStreet common stock, as applicable, held through brokerage firms. If your family has multiple accounts holding HomeStreet common stock, you may have already received a householding notification from your broker. Please contact your broker directly if you have any questions or require additional copies of this proxy statement/prospectus/consent solicitation statement. The broker will arrange for delivery of a separate copy of this proxy statement/prospectus/consent solicitation statement promptly upon your written or oral request. You may decide at any time to revoke your decision to household, and thereby receive multiple copies.
