On April 24, 2025, the Company announced that it had entered into a definitive merger agreement with Eastern Bankshares, Inc. (“Eastern”), the holding company for Eastern Bank, pursuant to which the Company will merge with and into Eastern in a stock and cash transaction.

Second Quarter Financial Highlights:

• Net income of $8.1 million, or $0.20 per diluted share

• Net interest margin of 2.52%, up 13 basis points quarter-over-quarter

• Noninterest income increased $2.3 million, or 23.6%, driven by higher mortgage banking income and higher swap and deposit fee income

• Noninterest expense was up $1.2 million, but down slightly excluding $1.7 million of merger-related expenses

• The share repurchase program was suspended pending completion of the merger with Eastern

“I’m pleased to report our steady financial improvement in the second quarter,” commented Joseph F. Casey, President and CEO, “including net interest margin expansion, improved core returns on assets and equity, and continued management of expenses.” He continued: “While we look forward to a successful merger with Eastern, the HarborOne team remains focused on continuing to provide superior service and a seamless transition to our customers, communities and employees.”

Net Interest Income

Net interest and dividend income increased $1.7 million from $31.5 million to $33.2 million, while net interest margin improved 13 basis points to 2.52% compared to the prior quarter, impacted by:

• Yield on loans increased 8 basis points partly due to an increase in prepayment fees of $721,000; average loan balances decreased $52.0 million, largely driven by a decline in commercial real estate loans, which were down $46.8 million on average.

• Cost of deposits, excluding brokered deposits, decreased 7 basis points; average deposit balances, excluding brokered deposits, increased $57.2 million, primarily due to an increase of $40.4 million in lower cost NOW and noninterest-earning deposits.

• Borrowing costs improved 2 basis points, and average borrowings declined $87.8 million.

The $1.9 million increase in net interest and dividend income from the prior year quarter reflects net interest margin improvement of 21 basis points, primarily due to higher prepayment fees, lower cost of funds, and lower average balances of funding liabilities.

Noninterest Income

Total noninterest income increased $2.3 million, or 23.6%, to $12.2 million, from $9.9 million for the first quarter of 2025, impacted by:

• HarborOne Mortgage, LLC (“HarborOne Mortgage”) realized a $3.4 million gain on loan sales from mortgage closings of $176.2 million in the second quarter of 2025, compared to $2.7 million from mortgage loan closings of $114.1 million in the first quarter. Mortgage rates were stable during the second quarter, and while for-sale inventory constrained loan demand, the typically strong spring market produced higher originations.

• The mortgage servicing rights (“MSR”) valuation decreased $546,000 compared to a decrease of $1.2 million for the first quarter of 2025, and the impact of principal payments on the underlying mortgages was $927,000 and $782,000 for the quarters ended June 30, 2025, and March 31, 2025, respectively. The second quarter MSR valuation loss of $546,000 was partially offset by a $349,000 economic hedging gain, whereas the first quarter of 2025 included a MSR valuation loss of $1.1 million offset by a $561,000 hedging gain.

• Deposit account fees increased $265,000, primarily as a result of an increase in debit card interchange fees of $179,000.

• Other income increased $948,000, primarily due to the receipt of an Employee Retention Tax Credit in the amount of $547,000, including interest, and $382,000 of swap fee income.

Total noninterest income increased $302,000 compared to the prior year quarter. The prior year results included a $1.8 million gain on disposal of an asset held for sale, partially offset by a $1.0 million loss on sale of securities.

Noninterest Expense

Total noninterest expense was $34.1 million for the quarter ended June 30, 2025, compared to $32.9 million for the quarter ended March 31, 2025; quarter-over-quarter variances of note were:

• Compensation and benefits expenses were flat in comparison to the prior quarter.

• Occupancy and equipment expenses decreased $359,000, primarily due to a seasonal decrease in landscaping expense.

• Marketing expense increased $277,000, due to a small business campaign in the second quarter of 2025.

• Deposit insurance decreased $136,000, reflecting a decrease in the assessment base.

• Merger expenses of $1.7 million were recorded in the second quarter of 2025, primarily for investment advisory and legal services.

Total noninterest expense increased $926,000 compared to the prior year quarter, primarily driven by the merger expenses, partially offset by decreases in compensation and benefits, occupancy and equipment expense, and marketing expenses.

Balance Sheet

Total assets decreased $91.3 million, or 1.6%, to $5.61 billion, from $5.70 billion at the prior quarter end, impacted by:

• Loans declined $93.8 million, or 1.9%, to $4.73 billion, from $4.82 billion the prior quarter. Commercial real estate and construction loans decreased $118.4 million, favoring payoffs over renewals for loans secured by commercial real estate. Commercial and industrial loans increased $16.5 million. Residential real estate and consumer loans increased $8.1 million, primarily reflecting an increase in home equity line of credit balances.

• Available-for-sale securities increased $21.6 million to $287.3 million from the prior quarter. The unrealized loss on securities available for sale decreased to $56.9 million, as compared to $58.8 million in the prior quarter. Securities held to maturity were steady at $19.2 million.

Non-certificate accounts decreased $66.5 million, and term certificate accounts decreased $7.5 million. Brokered deposits decreased $51.1 million. As of June 30, 2025, FDIC-insured deposits were approximately 73% of total deposits, including Bank subsidiary deposits.

• Total stockholders’ equity was $580.1 million, compared to $576.0 million at the prior quarter end. Stockholders’ equity increased 0.7% when compared to the prior quarter, as net income increases and an increase in the fair value of available-for-sale securities, were partially offset by share repurchases at the beginning of the quarter and dividend payments. The share repurchase program was suspended during the second quarter pending completion of the merger with Eastern Bank.

• The tangible-common-equity-to-tangible-assets ratio⁽¹⁾ was 9.38% at June 30, 2025, compared to 9.15% at March 31, 2025. Book value per share and tangible book value per share⁽¹⁾ increased quarter over quarter to $13.47 from $13.27 and to $12.09 from $11.90, respectively.

Asset Quality and Allowance for Credit Losses

The Company recorded a $739,000 provision for credit losses for the quarter ended June 30, 2025. The provision for loan credit losses was $355,000, and the provision for unfunded commitments was $384,000. The provision for loan credit losses was primarily due to a further specific reserve allocation for a previously identified classified commercial and industrial loan and qualitative factor adjustments, partially offset by a decrease in loan balances. During the quarter, a $1.7 million charge-off was recorded when a loan modification with a replacement borrower was resolved, resulting in a new loan recorded at fair value. At March 31, 2025, the provision for loan credit losses was $1.9 million, and the provision for unfunded commitments was a negative $506,000. The first quarter provision for loan credit losses was primarily due to a further specific reserve allocation for a previously identified classified commercial real estate loan, partially offset by a decrease in loan balances and qualitative factor adjustments.

Net charge-offs totaled $1.7 million, or 0.14% of average loans outstanding on an annualized basis for the quarter ended June 30, 2025, and for the quarter ended March 31, 2025, net charge-offs totaled $8.7 million, or 0.72% of average loans outstanding on an annualized basis. The charge-off in the first quarter of 2025 primarily reflects a charge-off on a single commercial real estate loan.

The allowance for credit losses (“ACL”) on loans was $48.0 million, or 1.01% of total loans, at June 30, 2025, compared to $49.3 million, or 1.02% of total loans, at March 31, 2025. The ACL on unfunded commitments, included in other liabilities on the unaudited Consolidated Balance Sheet, amounted to $3.4 million at June 30, 2025, compared to $3.0 million at March 31, 2025.

Use of Non-GAAP Measures

In addition to results presented in accordance with generally accepted accounting principles (“GAAP”), this press release contains certain non-GAAP financial measures including: “core net income,” “core earnings per common share,” “core return on average earning assets,” “core return on average earning equity,” “efficiency ratio,” “core efficiency ratio,” “tax equivalent efficiency ratio,” “tax equivalent core efficiency ratio,” “total adjusted noninterest expense”, “core noninterest expense,” “tax equivalent net interest and dividend income,” “total core noninterest income,” “tax equivalent total core revenue,” “tangible common equity,” “average tangible common equity,” “tangible assets,” “tangible book value per share,” “tangible common equity to tangible assets,” “return on average tangible common equity,” “core return on average tangible common equity” and certain ratios derived from these measures. Non-GAAP measures are utilized by management, regulators and market analysts to evaluate the Company’s financial position and therefore such information is useful to investors.

The tax equivalent basis adjusts for the tax-favored status from certain loans held by the Bank that are not taxable for federal income tax purposes.

Core net income, core noninterest income and core noninterest expense exclude certain items that management does not consider indicative of ongoing financial performance or enhances comparability of results with prior periods. These adjustments include gain or loss on the sale of certain assets and release of reserves for uncertain tax positions.

These disclosures should not be viewed as a substitute for financial results determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures which may be presented by other companies. Because non-GAAP financial measures are not standardized, it may not be possible to compare these financial measures with other companies’ non-GAAP financial measures having the same or similar names.
