Balance Sheet

Cash and cash equivalents increased $112.1 million, or 103.5%, to $220.5 million at September 30, 2023 from $108.4 million at June 30, 2023 due primarily to a decrease in investment securities.

Total investment securities decreased $136.4 million, or 6.7%, to $1.89 billion at September 30, 2023 from $2.03 billion at June 30, 2023. Total investment securities available for sale decreased $129.0 million due primarily to maturities and prepayments of $85.4 million which included $40.8 million in securities called during the quarter, as well as $47.2 million in investment securities sold at a loss of $1.9 million. The decreases in investment securities available for sale were partially offset by purchases of $22.7 million.

Total stockholders' equity decreased $6.2 million, or 0.8%, to $813.5 million at September 30, 2023 compared to $819.7 million at June 30, 2023 due primarily to an increase of $15.2 million in accumulated other comprehensive loss as a result of declining fair values of investment securities available for sale and $7.8 million in dividends paid offset partially by $18.2 million of net income recognized for the quarter.

Allowance for Credit Losses and Provision for Credit Losses

The allowance for credit losses ("ACL") on loans as a percentage of loans receivable was 1.10% at September 30, 2023 compared to 1.09% at June 30, 2023. During the third quarter of 2023, the Company recorded a $635,000 reversal of provision for credit losses on loans, compared to a $2.0 million provision for credit losses on loans during the second quarter of 2023. The reversal of the provision for credit losses on loans during the third quarter of 2023 was primarily driven by net recoveries for the quarter of $1.2 million.

During the third quarter of 2023, the Company recorded a $243,000 reversal of provision for credit losses on unfunded commitments compared to a $79,000 reversal of provision for credit losses on unfunded commitments during the second quarter of 2023. The increase in the reversal of provision for credit losses on unfunded commitments during the third quarter of 2023 was due primarily to an increase in loan utilization rates in commercial and industrial loans which reduced the unfunded exposure.

The following table provides detail on the changes in the ACL on loans and the ACL on unfunded, and the related (reversal of) provision for credit losses for the periods indicated:

Net Interest Income and Net Interest Margin

Net interest income decreased $206,000, or 0.4%, during the third quarter of 2023 compared to the second quarter of 2023 due primarily to an increase of $3.6 million in interest expense partially offset by a $3.4 million increase in interest income. Net interest margin decreased nine basis points to 3.47% during the third quarter of 2023 from 3.56% during the second quarter of 2023. The cost of interest bearing deposits increased 31 basis points to 1.23% for the third quarter of 2023 as compared to 0.92% for the second quarter of 2023. This increase was primarily due to customers transferring balances from non-maturity deposits to higher rate certificates of deposit and secondarily to an increase in brokered deposits. The yield on interest earning assets increased 12 basis points to 4.58% for the third quarter of 2023 as compared to 4.46% for the second quarter of 2023. The yield on loans receivable, net increased 11 basis points to 5.30% during the third quarter of 2023 as compared to 5.19% during the second quarter of 2023 due to higher rates on new and renewed loans. The yield on interest earning deposits increased 32 basis points to 5.42% during the third quarter of 2023 as compared to 5.10% during the second quarter of 2023 due to an increase in market rates.

Net interest income decreased $3.7 million, or 6.2%, during the third quarter of 2023 compared to the third quarter of 2022 and the net interest margin decreased ten basis points from 3.57% during this same period. The decrease was due primarily to an increase in interest expense due to an increase in deposit rates and borrowing expense partially offset by an increase in yields earned on interest earning assets following increases in market interest rates.

Noninterest Income

Noninterest income decreased during the third quarter of 2023 from the second quarter of 2023 and the same period in 2022 due primarily to a $1.9 million loss on sale of investment securities available for sale partially offset by a $610,000 gain on sale of the Ellensburg branch and related deposits which is included in other income.

The following table presents the key components of noninterest income and the change for the periods indicated:

Noninterest Expense

Noninterest expense decreased $355,000, or 0.9%, during the third quarter of 2023 from the second quarter of 2023. Compensation and employee benefits increased $227,000 as one-time adjustments to reduce incentive accruals were made during the second quarter of 2023. Professional services decreased due a decrease in contracted services during the third quarter of 2023. Other expense decreased primarily due to a decrease in customer account loss expense as compared to the second quarter of 2023.

Noninterest expense increased $1.8 million, or 4.7%, during the third quarter of 2023 compared to the same period in 2022 due primarily to an $802,000 increase in compensation and employee benefits resulting from an increase in the number of full-time equivalent employees including the addition of commercial and relationship banking teams in 2023 and an increase in salaries and wages due to upward market pressure. Occupancy and equipment expense increased due to the expansion into Eugene, Oregon and Boise, Idaho. Data processing costs increased due primarily to the expansion of digital services including the

addition of the ability to open accounts online. Federal deposit insurance premiums increased due to the increase in the assessment rate starting in January 2023.

The following table presents the key components of noninterest expense and the change for the periods indicated:

This press release includes "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Such statements often include words such as "believe," "expect," "anticipate," "estimate," and "intend" or future or conditional verbs such as "will," "would," "should," "could," or "may." Forward-looking statements are not historical facts but instead represent management's current expectations and forecasts regarding future events, many of which are inherently uncertain and outside of our control. Actual results may differ, possibly materially, from those currently expected or projected in these forward-looking statements. Factors that could cause the Company’s actual results to differ materially from those described in the forward-looking statements, include but are not limited to, the following: changes in general economic conditions nationally or in our local market areas, other markets where the Company has lending relationships, or other aspects of the Company’s business operations or financial markets including, without limitation, as a result of employment levels, labor shortages and the effects of inflation, a potential recession or slowed economic growth; changes in the interest rate environment, including the recent increases in the Board of Governors of the Federal Reserve System (the “Federal Reserve”) benchmark rate and duration at which such increased interest rate levels are maintained, which could adversely affect our revenues and expenses, the value of assets and obligations, and the availability and cost of capital and liquidity; the impact of continuing inflation and the current and future monetary policies of the Federal Reserve in response thereto; the impact of bank failures or adverse developments at other banks and related negative press about the banking industry in general on investor and depositor sentiment; the effects of any federal government shutdown; changes in the interest rate environment; the quality and composition of our securities portfolio and the impact of any adverse changes including market liquidity within the securities markets; legislative and regulatory changes, including changes in banking, securities and tax law, in regulatory policies and principles, or the interpretation of regulatory capital or other rules; credit and interest rate risks associated with the Company’s businesses, customers, borrowings, repayment, investment, and deposit practices; fluctuations in deposits; liquidity issues, including our ability to borrow funds or raise additional capital, if necessary; disruptions, security breaches, or other adverse events, failures or interruptions in, or attacks on, our information technology systems or on the third-party vendors who perform several of our critical processing functions; effects of critical accounting policies and judgments, including the use of estimates in determining fair value of certain of our assets, which estimates may prove to be incorrect and result in significant declines in valuation; and other factors described in Heritage's latest Annual Report on Form 10-K and Quarterly Reports on Form 10-Q and other documents filed with or furnished to the Securities and Exchange Commission (the “SEC”) which are available on our website at www.heritagebanknw.com and on the SEC's website at www.sec.gov.

NON-GAAP FINANCIAL MEASURES (Unaudited)

(Dollars in thousands, except per share amounts)

These forward-looking statements are subject to known and unknown risks, uncertainties and other factors that could cause our actual results for future periods to differ materially from those expressed in any forward-looking statements by, or on behalf of, the Company and could negatively affect the Company’s operating results and stock price performance. Factors that may cause such a difference include, but are not limited to: • potential adverse impacts to economic conditions nationally or in our local market areas, other markets where the Company has lending relationships, or other aspects of the Company’s business operations or financial markets, including, without limitation, as a result of employment levels, labor shortages and the effects of inflation, a potential recession or slowed economic growth; • changes in the interest rate environment, including the recent increases in the Board of Governors of the Federal Reserve System benchmark rate and duration at which such increased interest rate levels are maintained, which could adversely affect our revenues and expenses, the value of assets and obligations, and the availability and cost of capital and liquidity; • the impact of continuing inflation and the current and future monetary policies of the Federal Reserve in response thereto; • the impact of bank failures or adverse developments at other banks and related negative publicity about the banking industry in general on investor and depositor sentiment regarding the stability and liquidity of banks; • the effects of any federal government shutdown; • legislative or regulatory changes that adversely affect our business, including changes in banking, securities and tax law, in regulatory policies and principles, or the interpretation of regulatory capital or other rules; • credit and interest rate risks associated with the Company’s businesses, customers, borrowings, repayment, investment, and deposit practices; • fluctuations in deposits; • liquidity issues, including our ability to borrow funds or raise additional capital, if necessary; • disruptions, security breaches, or other adverse events, failures or interruptions in, or attacks on, our information technology systems or on the third-party vendors who perform several of our critical processing functions; • effects of critical accounting policies and judgments, including the use of estimates in determining fair value of certain of our assets, which estimates may prove to be incorrect and result in significant declines in valuation; and • the effects of climate change, severe weather events, natural disasters, pandemics, epidemics and other public health crises, acts of war or terrorism, and other external events on our business. Further, certain risks and important factors that could affect the Company’s future results are identified in its Annual Report on Form 10-K for the year ended December 31, 2022 and other reports filed by the Company with the Securities and Exchange Commission, including among other things under the heading “Risk Factors” in such Annual Report on Form 10-K. Any forward-looking statement speaks only as of the date on which it is made, and the Company undertakes no obligation to update any forward- looking statement, whether to reflect events or circumstances after the date on which the statement is made, to reflect new information or the occurrence of unanticipated events, or otherwise. Non-GAAP Financial Information The Company reports its results in accordance with United States generally accepted accounting principles (“GAAP”). However, management believes that certain non-GAAP performance measures used in managing the business may provide meaningful information about underlying trends in its business. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, the Company’s reported results prepared in accordance with GAAP. Slides containing a discussion and reconciliation of non-GAAP financial measures are contained at the end of this presentation. All dollars throughout the entire presentation are in millions unless otherwise noted, except per share amounts. FORWARD LOOKING STATEMENTS
