FIRST QUARTER 2016 NASDAQ:HMST

Important Disclosures Forward-Looking Statements This presentation includes forward-looking statements, as that term is defined for purposes of applicable securities laws, about our industry, our future financial performance and business plans and expectations. These statements are, in essence, attempts to anticipate or forecast future events, and thus subject to many risks and uncertainties. These forward-looking statements are based on our management's current expectations, beliefs, projections, future plans and strategies, anticipated events or trends, and similar expressions concerning matters that are not historical facts, as well as a number of assumptions concerning future events. Forward-looking statements in this release include, among other matters, statements regarding our business plans and strategies (including our expansion strategies) and the expected effects of those initiatives, general economic trends, particularly those that affect mortgage origination and refinance activity, and growth scenarios and performance targets. Readers should note, however, that all statements in this presentation other than assertions of historical fact are forward-looking in nature. These statements are subject to risks, uncertainties, assumptions and other important factors set forth in our SEC filings, including but not limited to our Annual Report on Form 10-K for year ended December 31, 2015, and our quarterly report on Form 10-Q for the quarter ended March 31, 2016, which we expect to file on or before May 10, 2016. Many of these factors are beyond our control. Such factors could cause actual results to differ materially from the results discussed or implied in the forward-looking statements. These risks include statements predicated on our ability to realize the expected value of our mergers with Simplicity Bancorp and Orange County Business Bank and the combined entity resulting from those transactions; integrate our recent acquisitions; continue to expand our banking operations geographically and across market sectors; grow our franchise and capitalize on market opportunities; manage our growth efforts cost-effectively and attain the desired operational and financial outcomes; manage the losses inherent in our loan portfolio; make accurate estimates of the value of our non-cash assets and liabilities; maintain electronic and physical security of customer data; respond to an increasingly restrictive and complex regulatory environment; and attract and retain key personnel. Actual results may fall materially short of our expectations and projections, and we may change our plans or take additional actions that differ in material ways from our current intentions. Accordingly, we can give no assurance of future performance, and you should not rely unduly on forward-looking statements. All forward-looking statements are based on information available to the Company as of the date hereof, and we do not undertake to update or revise any forward-looking statements, for any reason. Basis of Presentation of Financial Data Unless noted otherwise in this presentation, all reported financial data is being presented as of the period ending March 31, 2016, and is unaudited, although certain information related to the year ended December 31, 2015, has been derived from our audited financial statements. All financial data should be read in conjunction with the notes in our consolidated financial statements. Non-GAAP Financial Measures Information on any non-GAAP financial measures such as core measures or tangible measures referenced in this presentation, including a reconciliation of those measures to GAAP measures, may also be found in the appendix, our SEC filings, and in the earnings release available on our web site. 2

Mortgage Banking Segment – Quarter Trend • 1Q interest rate lock commitment volume of $1.8 billion was 35% higher than in 4Q and closed loan volume of $1.6 billion was 5% lower than in the prior quarter • Higher rate lock volume was the primary driver of net gain on mortgage loan origination and sale activities of $59.5 million coming in 37% above 4Q • Mortgage servicing income of $7.3 million declined $5.5 million from the prior quarter primarily due to lower risk management results offset somewhat by an increase in collected servicing fee income 23 ($ in thousands) Mar. 31, 2016 Dec. 31, 2015 Sept. 30, 2015 Jun. 30, 2015 Mar. 31, 2015 Net interest income $ 5,044 $ 6,981 $ 8,125 $ 7,585 $ 5,627 Noninterest income 67,065 56,631 60,584 69,363 65,292 Noninterest expense 64,722 63,183 63,916 63,055 53,816 Net income before taxes 7,387 429 4,793 13,893 17,103 Income taxes 2,522 128 1,632 4,371 6,785 Net income $ 4,865 $ 301 $ 3,161 $ 9,522 $ 10,318 ROAA 2.50% 0.12% 1.11% 3.44% 4.56% ROATE 21.73% 1.28% 10.28% 26.84% 35.16% Efficiency Ratio 89.8% 99.3% 93.0% 81.9% 75.9% FTE 1,361 1,311 1,293 1,207 1,061 For the three months ended

Mortgage Market & Competitive Landscape 26 Mortgage Market • MBA estimates first quarter mortgage origination nationally to decrease 14% over fourth quarter. By contrast, HomeStreet’s originations decreased only 5% over the prior quarter. • The most recent Mortgage Bankers Association monthly forecast projects total loan originations to decrease 4.4% in 2016 over the past year, an upward revision from its prior quarter forecast of a 7.1% decrease. However, our focus has always been on the purchase market and purchase mortgage originations are projected to increase 10% in 2016. • Despite the increase in short term interest rates by the Federal Reserve in December, mortgage rates continue near historic lows, and nationally purchases are expected to increase by 10% from 2015 and comprise 62% of volume in 2016 • Housing starts for this year are expected to be up 11% over 2015 levels Competitive Landscape • Purchases comprised 53% of originations nationally and 49% in the Pacific Northwest in the first quarter. HomeStreet continues to perform above the national and regional averages, with purchases accounting for 62% of our closed loans and 59% of our interest rate lock commitments in the quarter. • Purchase demand continues to remain strong in many of our our markets, however limited inventory continues to be a significant constraining issue • The Pacific Northwest and the major markets in western United States are expected to continue to grow more quickly than the rest of the country

Earnings Guidance 27 • Currently anticipating mortgage loan lock and forward sale commitments volume of approximately $2.3 billion in the second and third quarters and $1.8 billion in the fourth quarter of this year • Projecting mortgage loan held for sale closing volumes of $2.3 billion, $2.4 billion, and $2.1 billion in the second, third, and fourth quarters of this year, respectively • Gain on sale composite margin expected to range between 315 and 325 basis points over the next three quarters • In our Commercial and Consumer Banking segment, over the next three quarters we continue to expect net loan portfolio growth to approximate 4% to 6% quarterly • Overall, we generally expect our consolidated net interest margin to trend down to the 3.40% to 3.45% level reflecting a flatter yield curve, absent changes in market rates and prepayment speeds • Our non-interest expenses will grow approximately 3% per quarter on average, reflecting the continued investment in our growth and infrastructure
