HERITAGE FINANCIAL CORP /WA/

We maintain sufficient cash and cash equivalents and investment securities to meet short-term liquidity needs and actively monitor our long-term liquidity position to ensure the availability of capital resources for contractual obligations, strategic loan growth objectives and to fund operations. Our funding strategy has been to focus on acquiring non-maturity deposits from our retail accounts, and noninterest bearing demand deposits from our commercial customers and to use our borrowing availability to fund growth in assetfs. Our liquidity policy permits the purchase of brokered deposits in an amount not to exceed 15% of the Company's total deposits as a secondary source for funding.

The Company’s total uninsured deposits, which are the amounts of deposit accounts that exceed the FDIC insurance limit, currently $250,000, were approximately $2.85 billion, or 39.6% of total deposits, at September 30, 2026 and $2.43 billion, or 41.1% of total deposits, at December 31, 2025. These amounts were estimated based on the same methodologies and assumptions used for regulatory reporting purposes. At September 30, 2026, we had no brokered deposits, compared to $77.5 million, or 1.31% of total deposits, at December 31, 2025. Borrowings may be used on a short-term basis to compensate for reductions in other sources of funds (such as deposit inflows at less than projected levels). Borrowings may also be used on a longer-term basis to support expanded lending activities and match the maturity of repricing intervals of assets. While maturities and scheduled amortization of loans are a predictable source of funds, deposit flows and loan prepayments are greatly influenced by the level of interest rates, economic conditions and competition so we adhere to internal management targets assigned to the loan to deposit ratio, liquidity ratio, net short-term non-core funding ratio and non-core liabilities to total assets ratio to ensure an appropriate liquidity position. The Company regularly monitors liquidity, models liquidity stress scenarios to ensure that adequate liquidity is available, and has contingency funding plans in place, which are reviewed and tested on a regular, recurring basis.

The following table summarizes the Company's available liquidity as of the dates indicated:

(1) Investment securities available for sale at fair value.

(2)Includes FHLB borrowing availability of $1.79 billion at September 30, 2026 based on pledged assets; however, maximum credit capacity is 45% of the Bank's total assets one quarter in arrears, or $3.79 billion.

Management believes the capital sources are adequate to meet all reasonably foreseeable short-term and long-term cash requirements and there has not been a material change in our capital resources since the information disclosed in our 2025 Annual Form 10-K. We are not aware of any reasonably likely material changes in the mix and relative cost of such resources.
