HERITAGE FINANCIAL CORP WA

One of the Company's key sources of revenue is net interest income. Several factors affect net interest income, including, but not limited to: the volume, pricing, mix and maturity of interest earning assets and interest bearing liabilities; the volume of noninterest earning assets, noninterest bearing demand deposits, other noninterest bearing liabilities and stockholders' equity; market interest rate fluctuations; and asset quality.

The following table provides relevant net interest income information for the periods indicated:

(1) Average balances are calculated using daily balances. Average yield/rate is annualized.

(2) Average loans receivable, net includes loans held for sale and loans classified as nonaccrual, which carry a zero yield. Interest earned on loans receivable, net includes the amortization of net deferred loan fees of $971,000 and $726,000 for the three months ended June 30, 2024 and 2023, respectively.

(3)Yields on tax-exempt loans and securities have not been stated on a tax-equivalent basis.

Interest income on loans receivable, net, and interest earning deposits increased due to increases in both the average yield earned on and the average outstanding balance of those assets.
