Insights

Q1 2026 shows merger-fueled balance sheet growth, wider margins, and solid credit despite higher expenses.

Heritage Financial closed the $185.0 million Olympic Bancorp acquisition, issuing 7,167,600 shares and adding $1.59 billion of assets. This lifted total assets to $8.50 billion, loans to $5.72 billion, and deposits to $7.25 billion. Net interest income rose $15.5 million year over year, and net interest margin improved to 3.96%, aided by a 5.73% loan yield and lower 1.71% cost of interest-bearing deposits.

Merger-related costs of $5.2 million pushed the efficiency ratio to 72.6%, though the adjusted efficiency ratio was lower at 63.3%. Credit quality metrics remained conservative, with nonperforming assets at 0.19% of total assets, nonaccrual loans at 0.26% of loans, and net charge-offs running at 0.04% of average loans annualized. Capital stayed comfortably above “well-capitalized” levels, including a leverage ratio of 10.3% and total capital ratio of 13.5%.

Liquidity was robust, with total available sources of $3.20 billion, covering 44.2% of total deposits and 113.0% of estimated uninsured deposits as of March 31, 2026. The regular quarterly dividend of $0.24 per share continues cash returns to shareholders alongside an adjusted return on average tangible common equity of 13.36%. Subsequent company filings may provide more detail on post-merger cost savings as the system conversion targeted for the end of Q3 2026 progresses.

5 terms

net interest margin financial

"Net interest margin increased 24 basis points to 3.96% during the first quarter of 2026"

Net interest margin measures how much a bank earns from lending and investing compared with what it pays for funding, expressed as a percentage of its interest-earning assets. Think of it like a grocery store’s markup: it shows the gap between buying cost and selling price per dollar of goods — here, the cost is interest paid and the sale is interest received. Investors watch it because a higher margin usually means a bank is more profitable and better at managing interest rate and credit conditions.

allowance for credit losses financial

"The allowance for credit losses ("ACL") on loans as a percentage of loans receivable was 1.06% at March 31, 2026"

Allowance for credit losses is a reserve set aside by a financial institution to cover potential losses from borrowers who may not repay their loans. It acts like a safety net, helping the institution prepare for loans that might turn sour. For investors, it signals how cautious the institution is about the quality of its loans and potential risks to its financial health.

Purchased Seasoned Loans financial

"Under the updated guidance, the acquired financial assets were classified as either Purchased Credit Deteriorated ("PCD") ... or Purchased Seasoned Loans ("PSLs")."

Purchased seasoned loans are existing loans that an investor buys after they have been outstanding for some time and have a track record of payments. Like buying a used car with a known service history, these loans give buyers clearer information about how likely borrowers are to keep paying, which helps investors estimate future cash flow, potential losses, and the returns they can expect.

tangible common equity financial

"Tangible common equity to tangible assets (1) | 9.6 | | | 10.1"

Tangible common equity is the portion of a company’s net worth that belongs to ordinary shareholders after removing intangible items (like goodwill or patents) and any preferred claims; it’s often expressed on a per-share basis. Think of it as the hard, sellable value left for common owners if you removed non-physical assets and paid off debts—investors use it to judge how much real cushion a company has and whether the stock might be under- or over-valued.

efficiency ratio financial

"Efficiency ratio | 72.6 | | | 62.5"

A measure of how much a company spends to produce each dollar of revenue, usually shown as operating expenses divided by revenue and expressed as a percentage. Think of it as a household’s budget: a lower percentage means more of each dollar earned stays as profit, while a higher number means costs are eating into returns. Investors use it to judge cost control and compare how efficiently companies turn revenue into earnings, especially in banks and financial firms.

Acquisition of Olympic Bancorp, Inc. (the "Merger")

On January 31, 2026, the Company completed the acquisition of Olympic, the holding company for Kitsap Bank. As of the acquisition date, Olympic was merged with and into Heritage and Kitsap Bank was merged with and into Heritage Bank.

Pursuant to the Agreement and Plan of Merger, each issued and outstanding share of Olympic capital stock was exchanged for 45.0 shares of Heritage common stock, with cash paid in lieu of fractional shares. After the Merger was completed, based on the number of issued and outstanding shares of Olympic capital stock on January 30, 2026 (the trading day immediately preceding the completion of the Merger), 7,167,600 shares of Heritage common stock were issued as Merger consideration. Based on the closing price of Heritage common stock on Nasdaq as of January 30, 2026 of $25.81, the Merger consideration that an Olympic shareholder was entitled to receive for each share of Olympic capital stock owned had a value of $1,161.45 with an aggregate transaction value of approximately $185.0 million.

Acquisition Accounting

The Merger was accounted for using the acquisition method. Accordingly, Heritage’s cost to acquire Olympic was allocated to the assets (including identifiable intangible assets) and the liabilities at their respective estimated fair values as of the acquisition date. The excess of the purchase price over the fair value of the net assets acquired was allocated to goodwill.

Heritage adopted Financial Accounting Standards Board Accounting Standards Update 2025-08 as of January 1, 2026. Under the updated guidance, the acquired financial assets were classified as either Purchased Credit Deteriorated ("PCD"), loans that have experienced more than insignificant credit deterioration since origination, or Purchased Seasoned Loans ("PSLs"). Per ASC 326-20-30-16, all loans that are acquired as part of a business combination accounted for using the acquisition method in accordance with Subtopic 805-20 that do not meet the definition of a PCD loan are determined to be PSLs. Under both classifications, the gross-up approach is applied whereby the estimated allowance for credit loss as of the acquisition date is added back to the fair value to determine the gross amortized cost basis.

Fair values on the acquisition date are preliminary and represent management’s best estimates based on available information and facts and circumstances in existence on the acquisition date. Fair values are subject to refinement for up to one year after the closing date of the acquisition as additional information regarding the closing date fair values becomes available.

The following table provides the estimated fair value of the assets acquired and liabilities assumed at the Merger date of January 31, 2026:

Total Assets

The Company’s total assets increased $1.53 billion, or 22.0%, to $8.50 billion at March 31, 2026 from $6.97 billion at December 31, 2025 primarily as a result of the Merger. Assets acquired, including goodwill, from the Merger totaled $1.59 billion at the closing date of January 31, 2026.

Investment Securities

Total investment securities increased $387.8 million, or 30.3%, to $1.67 billion at March 31, 2026, from $1.28 billion at December 31, 2025.

The Company repositioned a portion of the portfolio acquired in the Merger during the first quarter of 2026, with sales of $193.5 million and purchases of $315.9 million. Purchases exceeded sales in the repositioning due to the investment of excess cash acquired in the Merger, which was a result of the sale of securities by Olympic during the month preceding the Merger. Investment maturities and repayments totaled $44.5 million during the first quarter of 2026.

Allowance for Credit Losses and Provision for Credit Losses

The allowance for credit losses ("ACL") on loans as a percentage of loans receivable was 1.06% at March 31, 2026 compared to 1.10% at December 31, 2025. The decrease in the ACL as a percentage of loans was due primarily to the addition of the loan portfolio acquired in the Merger, which had a lower weighted average life of loans contributing to a lower ACL. On January 31, 2026, the Company recorded an initial ACL of $9.3 million for the PSL and PCD loans under ASU 2025-08 as part of the acquisition of Olympic. The ACL on loans as a percentage of loans receivable for the acquired portfolio as of the acquisition date was 0.98%.

During the first quarter of 2026, the Company recorded a $0.8 million reversal of provision for credit losses on loans, compared to a $0.9 million reversal of provision during the fourth quarter of 2025. During the first quarter of 2026, the Company recorded a $210,000 reversal provision for credit losses on unfunded commitments compared to a $95,000 provision during the fourth quarter of 2025. The reversal of provision for credit losses on unfunded commitments during the first quarter of 2026 was due primarily to an increase in utilization rates.

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

Credit Quality

Classified loans (loans rated substandard or worse) increased $4.5 million from the prior quarter and was due primarily to the addition of classified loans acquired from Olympic of $11.4 million, offset by loan payoffs. The percentage of classified loans to loans receivable decreased to 2.1% at March 31, 2026, compared to 2.4% at December 31, 2025 due to an increase in total loans as a result of the Merger during the first quarter of 2026.

Nonaccrual loans decreased by $6.0 million during the first quarter of 2026 due primarily to principal payoffs of one $5.8 million residential construction loan, one $1.5 million CRE non-owner occupied loan, and one $0.5 million CRE owner-occupied loan, offset partially by the migration of three commercial and industrial loans totaling $2.6 million, one $0.5 million CRE owner-occupied loan, and one $0.2 million residential construction loan. Olympic did not have any nonaccrual loans as of the acquisition date of January 31, 2026.

Net Interest Income and Net Interest Margin

Net interest income increased $10.9 million, or 18.6%, during the first quarter of 2026 compared to the fourth quarter of 2025 due to an $11.8 million increase in total interest income, offset partially by an increase in interest expense of $1.0 million. The increase in net interest income was primarily due to an increase in average interest earning assets, which grew substantially as a result of the Merger.

Net interest margin increased 24 basis points to 3.96% during the first quarter of 2026, from 3.72% during the fourth quarter of 2025. The increase in net interest margin was due primarily to the increase in net interest income as discussed above with the primary contributor being increases in both the average loan balance and loan yield as a result of the Merger.

The yield on interest earning assets increased 16 basis points to 5.19% for the first quarter of 2026, compared to 5.03% for the fourth quarter of 2025. The yield on loans receivable increased 19 basis points to 5.73% during the first quarter of 2026, compared to 5.54% during the fourth quarter of 2025. The increase was due primarily to the incremental accretion on purchased loans which contributed 12 basis points to loan yield and interest income recognized on nonaccrual loans which contributed six basis points to loan yield. The incremental accretion and the impact to loan yield will change during any period based on the volume of prepayments, but is expected to decrease over time as the balance of the purchased loans decreases.

The cost of interest bearing deposits decreased 12 basis points to 1.71% for the first quarter of 2026, from 1.83% for the fourth quarter of 2025. This decrease was primarily due to the deposits acquired from Olympic, which had a lower cost of deposits.

Net interest margin increased 52 basis points to 3.96% during the first quarter of 2026, compared to 3.44% for the same period in the prior year. Net interest income increased $15.5 million, or 28.9%, during the first quarter of 2026 compared to the same period in the prior year. The increase was due primarily to an increase in average interest earning assets, which increased substantially as a result of the Merger.

(1) Represents a non-GAAP financial measure. See “Non-GAAP Financial Measures” section for a reconciliation to the comparable GAAP financial measure.

(2)Represents the amount of interest income recorded on purchased loans in excess of the contractual stated interest rate in the individual loan notes due to incremental accretion of purchased discount or premium. Purchased discount or premium is the difference between the contractual loan balance and the fair value of acquired loans at the acquisition date. The purchased discount is accreted into income over the remaining life of the loan. The impact of incremental accretion on loan yield will change during any period based on the volume of prepayments, but it is expected to decrease over time as the balance of the purchased loans decreases.

Noninterest Income

Noninterest income increased $712,000 to $8.7 million during the first quarter of 2026 from $8.0 million during the fourth quarter of 2025. The increase was due primarily to increases in service charges and other fees, card revenue and other income due to income from the acquired deposit portfolio, offset partially by a decrease in interest rate swap fees due to decreased swap activity.

Noninterest income increased $4.8 million during the first quarter of 2026 from the same period in 2025 due primarily to a $3.9 million loss recognized in the first quarter of 2025 resulting from the sale of investment securities as part of the strategic repositioning of the Company's balance sheet, and due to increases in service charges and other fees, card revenue, and BOLI income due to income from the acquired deposit portfolio and acquired BOLI.

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

Noninterest Expense

Noninterest expense increased $15.1 million, or 36.3%, to $56.6 million during the first quarter of 2026, compared to $41.5 million in the fourth quarter of 2025. The increases were primarily due to expenses from the Merger, including increases related to compensation and employee benefits due to increased headcount, severance expense, occupancy and equipment expense primarily due to additional rent expense, and additional data processing expense due to an increase in transactional accounts and balances. Noninterest expense also increased due to an increase in the amortization of intangible assets of $1.8 million, relating to the Merger. Professional fees increased due primarily to Merger-related costs recognized in the first quarter of 2026. Total Merger-related costs, which consisted of severance expense, professional fees, core conversion costs, and contract termination costs incurred in the first quarter of 2026 were $5.2 million compared to $385,000 in the fourth quarter of 2025.

Noninterest expense increased $15.2 million, or 36.7%, during the first quarter of 2026 compared to the same period in 2025 due primarily to an increase in expenses related to the Merger.
