Rockland, Massachusetts (July 16, 2026) - Independent Bank Corp.

BALANCE SHEET

    

Total assets of $25.0 billion at June 30, 2026 increased $190.3 million, or 0.8%, compared to the prior quarter, driven primarily by increased cash balances from strong late quarter deposit growth.

Total loans of $18.4 billion at June 30, 2026 decreased $31.2 million, or 0.2%, compared to the prior quarter:

•The commercial and industrial portfolio grew $79.4 million, or 1.7% (6.8% annualized), inclusive of $36.8 million in runoff attributable to the Company’s strategic exit from the dealer finance business.

•Commercial real estate and construction decreased $176.4 million, or 1.8%, due to elevated payoffs and amortization of balances.

•The total consumer real estate portfolio increased $63.2 million, or 1.5% (6.1% annualized), fueled by solid demand in both the residential and home equity portfolios. Residential balances increased $28.1 million, or 1.0% (4.0% annualized) while home equity balances increased by $35.1 million, or 2.7% (10.8% annualized).

Total deposits increased by $294.6 million, or 1.5%, to $20.4 billion at June 30, 2026, as compared to the prior quarter, while average balances were consistent at $19.9 billion:

•Growth in period end deposits was fueled primarily by inflows in municipal and business accounts.

•Overall core deposits comprised 84.1% of total deposits at June 30, 2026, as compared to 83.8% at March 31, 2026.

•Total noninterest bearing demand deposits were 28.0% of total deposits at both June 30, 2026 and March 31, 2026.

•The total cost of deposits for the second quarter remained flat compared to the prior quarter at 1.36%.

Total period end borrowings decreased by $74.8 million, or 9.6%, during the second quarter of 2026, reflecting approximately $100 million in net paydowns on Federal Home Loan Bank borrowings, partially offset by $25.0 million advanced on a working capital line of credit.

The Company’s total securities portfolio of $3.3 billion decreased by $59.3 million, or 1.8% (7.0% annualized), from the prior quarter:

•New purchases of $69.7 million in the available for sale portfolio were offset by maturities, calls, and paydowns in the combined available for sale and held to maturity portfolios during the quarter. Unrealized losses of $11.1 million recorded in the available for sale portfolio also contributed to the second quarter decrease.

---

•Total securities represented 13.3% and 13.6% of total assets at June 30, 2026 and March 31, 2026, respectively.

Stockholders’ equity at June 30, 2026 decreased $29.7 million, or 0.8%, compared to March 31, 2026, as strong earnings were offset by the impact of share repurchases, dividends, and unrealized losses on available for sale securities recognized in other comprehensive income during the quarter:

•The Company repurchased approximately 964,000 shares for $75.0 million during the second quarter of 2026 at an average price of $77.79 per share.

•The Company’s ratio of common equity to assets of 14.06% at June 30, 2026 represented a decrease of 23 basis points from March 31, 2026.

•The Company’s ratio of tangible common equity to tangible assets of 9.69% at June 30, 2026 represented a decrease of 17 basis points from the prior quarter and a decrease of 123 basis points from the year ago period(1).

•The Company’s book value per share increased by $0.84, or 1.2%, to $73.76 at June 30, 2026 as compared to the prior quarter.

NET INTEREST INCOME

        

Net interest income of $210.9 million for the second quarter of 2026 decreased $1.5 million, or 0.7%, when compared to the prior quarter:

•The net interest margin of 3.85% decreased 5 basis points compared to the prior quarter, as the benefit of asset repricing was offset by a 9 basis point decrease in purchase accounting accretion. Excluding purchase accounting accretion and other non-core items, the adjusted margin of 3.76%(1) increased 4 basis points.

•Total loan yields decreased 8 basis points to 5.69% from 5.77%, driven primarily by the impact of lower purchase accounting accretion compared to the prior quarter, partially offset by loan repricing benefit. Excluding purchase accounting accretion and other non-core items, the adjusted loan yield(1) increased 3 basis points during the quarter. Securities yields increased 5 basis points to 3.13% compared to the prior quarter, reflecting the impact of higher yielding new purchases throughout the first half of 2026.

•The Company’s overall cost of funding remained flat at 1.52% for the second quarter of 2026.

NONINTEREST INCOME

Noninterest income of $42.4 million for the second quarter of 2026 represented an increase of $2.1 million, or 5.3%, as compared to the prior quarter. Significant changes in noninterest income for the second quarter of 2026 compared to the prior quarter included the following:

•Interchange and ATM fees increased by $668,000, or 13.3%, driven by seasonally higher transaction volumes.

•Overall investment and advisory income increased $796,000, or 5.6%, driven by seasonal tax preparation fees and higher asset-based fee revenue compared to the prior quarter, partially offset by lower insurance

•Salaries and employee benefits decreased by $1.6 million, or 2.0%, driven primarily by decreased incentive compensation and lower payroll taxes, partially offset by increases in base salaries and retirement contributions.

•Occupancy and equipment expenses decreased by $1.1 million, or 6.6%, driven primarily by lower snow removal and utilities costs during the quarter, partially offset by increases in general maintenance and repair costs.

•Other noninterest expense increased by $3.5 million, or 12.3%, driven primarily by a $1.0 million increase in one-time costs associated with the Company’s upcoming core conversion, along with increases in annual director equity compensation of $878,000, legal fees of $807,000, and recruitment costs of $326,000.

update publicly any such forward-looking statements, whether in response to new information, future events or otherwise. Any public statements or disclosures by the Company following this release which modify or impact any of the forward-looking statements contained in this release will be deemed to modify or supersede such statements in this release. In addition to the information set forth in this press release, you should carefully consider the Risk Factors.

This press release and the appendices attached to it contain financial information determined by methods other than in accordance with accounting principles generally accepted in the United States of America (“GAAP”). This information may include operating net income and operating earnings per share (“EPS”), operating return on average assets, operating return on average common equity, operating return on average tangible common equity, adjusted net interest margin (“adjusted margin”) and the associated adjusted loan yield (which is calculated by dividing annualized interest income on loans, plus or minus non-core or other adjustments, by average loans), tangible book value per share and the tangible common equity ratio.

Operating net income, operating EPS, operating return on average assets, and operating return on average common equity exclude items that management believes are unrelated to the Company’s core banking business such as merger and acquisition expenses, and other items, if applicable. Management uses operating net income and related ratios and operating EPS to measure the strength of the Company’s core banking business and to identify trends that may to some extent be obscured by such items. Management reviews its adjusted margin and adjusted loan yield to determine any items that may impact these metrics that may be one-time in nature or not reflective of the core operating environment, such as significant purchase accounting adjustments or other adjustments such as nonaccrual interest reversals/recoveries and prepayment penalties. Management believes that adjusting for these items to arrive at an adjusted margin and adjusted loan yield provides additional insight into the operating environment and how management decisions impact the net interest margin.

Management also supplements its evaluation of financial performance with analysis of tangible book value per share (which is computed by dividing stockholders’ equity less goodwill and identifiable intangible assets, or “tangible common equity,” by common shares outstanding), the tangible common equity ratio (which is computed by dividing tangible common equity by “tangible assets,” defined as total assets less goodwill and other intangibles), and return on average tangible common equity (which is computed by dividing net income by average tangible common equity). The Company has included information on tangible book value per share, the tangible common equity ratio and return on average tangible common equity because management believes that investors may find it useful to have access to the same analytical tools used by management.  As a result of merger and acquisition activity, the Company has recognized goodwill and other intangible assets in conjunction with business combination accounting principles.  Excluding the impact of goodwill and other intangibles in measuring asset and capital values for the ratios provided, along with other bank standard capital ratios, provides a framework to compare the capital adequacy of the Company to other companies in the financial services industry.

These non-GAAP measures should not be viewed as a substitute for operating results and other financial measures determined in accordance with GAAP. An item which management excludes when computing these non-GAAP measures can be of substantial importance to the Company’s results for any particular quarter or year. The Company’s non-GAAP performance measures, including operating net income, operating EPS, operating return on average assets, operating return on average common equity, adjusted margin, tangible book value per share and the tangible common equity ratio, are not necessarily comparable to non-GAAP performance measures which may be presented by other companies.
