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:

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.

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.

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.

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.
