INDEPENDENT BANK CORP. REPORTS FIRST QUARTER NET INCOME OF $47.8 MILLION

Results reflect underlying strength of franchise

Rockland, Massachusetts (April 18, 2024) - Independent Bank Corp. (Nasdaq Global Select Market: INDB), parent of Rockland Trust Company, today announced 2024 first quarter net income of $47.8 million, or $1.12 per diluted share, compared to 2023 fourth quarter net income of $54.8 million, or $1.26 per diluted share.

The Company generated a return on average assets of 1.00% and a return on average common equity of 6.63% for the first quarter of 2024, as compared to 1.13% and 7.51%, respectively, for the prior quarter.

"Our first quarter results reflect our steady commitment to focusing on our core fundamentals – disciplined growth, core funding prioritization, strong credit monitoring, and expense management. We remain confident that we are well-positioned to create long term value for our shareholders while successfully navigating through this challenging macro environment", said Jeffrey Tengel, the Chief Executive Officer of Independent Bank Corp. and Rockland Trust Company.

BALANCE SHEET

Total assets of $19.3 billion at March 31, 2024 remained relatively consistent with the prior quarter level and decreased by $117.7 million, or 0.6%, as compared to March 31, 2023.

Total loans at March 31, 2024 of $14.3 billion increased by $52.5 million, or 0.4% (1.5% annualized), compared to the prior quarter level. This growth was primarily driven by the commercial real estate loan portfolio, which increased $67.3 million, or 0.8% (3.4% annualized) for the quarter, primarily reflecting transfers from the construction portfolio, modest new origination activity, and reduced levels of paydowns. The small business portfolio also continued its steady growth, rising by 3.9% during the first quarter of 2024, while the total consumer real estate portfolio remained generally in line with the prior quarter.

Deposit levels also resumed growth during the quarter, with balances of $15.0 billion at March 31, 2024, rising by $177.7 million, or 1.2%, from December 31, 2023. This increase was driven primarily by municipal deposit inflows and consumer demand for higher cost time deposits, partially offset by seasonal business deposit outflows. Though some level of product remixing persists, total noninterest bearing demand deposits comprised 29.7% of total deposits at March 31, 2024. Core deposits, inclusive of reciprocal deposits, represented 83.2% of total deposits at March 31, 2024, as compared to 84.6% at December 31, 2023. The total cost of deposits for the first quarter increased 17 basis points to 1.48% compared to the prior quarter, reflective of the competitive market environment and ongoing customer preference for higher yielding accounts.

In conjunction with deposit growth during the quarter, total borrowings declined by $193.0 million, or 15.8%, during the first quarter of 2024. The decrease was driven primarily by a reduction in Federal Home Loan

1

Bank borrowings of $143.0 million, or 12.9%. Additionally, the Company fully redeemed its outstanding subordinated debentures with an aggregate principal amount of $50.0 million.

The securities portfolio decreased by $85.1 million, or 2.9%, compared to December 31, 2023, driven primarily by paydowns, maturities, and unrealized losses of $4.0 million in the available for sale portfolio. Total securities represented 14.7% of total assets at March 31, 2024, as compared to 15.1% at December 31, 2023.

During the first quarter of 2024, the Company repurchased 532,266 shares of its common stock for $31.0 million at an average price per share of $58.22, marking the completion of its previously announced $100 million buyback program. Stockholders' equity at March 31, 2024 remained generally consistent when compared to December 31, 2023, as the impact of share repurchase activity and the common dividend declared during the first quarter was offset by strong earnings. The Company's ratio of common equity to assets of 14.92% at March 31, 2024 represented a decrease of 4 basis points from December 31, 2023 and an increase of 36 basis points from March 31, 2023. The Company's book value per share increased by $0.41, or 0.6%, to $67.94 at March 31, 2024 as compared to the prior quarter. The Company's tangible book value per share at March 31, 2024 rose by $0.21, or 0.5%, from the prior quarter to $44.34, and represented an increase of 7.3% from the year ago period. The Company's ratio of tangible common equity to tangible assets of 10.27% at March 31, 2024 represented a decrease of 4 basis points from the prior quarter and an increase of 38 basis points from the year ago period. Please refer to Appendix A for a detailed reconciliation of Non-GAAP balance sheet metrics.

NET INTEREST INCOME

Net interest income for the first quarter of 2024 decreased 5.3% to $137.4 million compared to $145.1 million for the prior quarter, as rising deposit costs continued to counter the benefit of repriced assets, resulting in a reduction in net interest margin of 15 basis points to 3.23% for the quarter.

NONINTEREST INCOME

Noninterest income of $29.9 million for the first quarter of 2024 represented a decrease of $2.1 million, or 6.6%, as compared to the prior quarter. Significant changes in noninterest income for the first quarter of 2024 compared to the prior quarter included the following:

•Investment management and advisory income increased by $123,000, or 1.3%, primarily driven by elevated asset-based revenue, which increased by $277,000, or 3.2%, offset by slightly lower commission and other revenue. Total assets under administration increased by $266.1 million, or 4.1%, to a record level of $6.8 billion at March 31, 2024.

•Mortgage banking income grew by $187,000, or 30.7%, driven primarily by a greater portion of new originations sold in the secondary market versus being retained in the Company's portfolio.

•Loan level derivative income decreased by $722,000, or 90.0% primarily due to lower demand.

•Other noninterest income decreased by $1.5 million, or 19.8%, driven primarily by volatility in non-core components, including lower unrealized gains on equity securities, while the prior quarter also included an outsized $1.0 million gain from the purchase of discounted tax credits.

NONINTEREST EXPENSE

Noninterest expense of $99.9 million for the first quarter of 2024 represented a decrease of $860,000, or 0.9%, as compared to the prior quarter. Significant changes in noninterest expense for the first quarter compared to the prior quarter included the following:

2

•Salaries and employee benefits increased by $786,000, or 1.4%, due primarily to seasonal increases in payroll taxes, partially offset by decreased commissions and equity compensation.

•Occupancy and equipment expenses increased by $413,000, or 3.2%, due mainly to seasonal increases in snow removal and utilities costs, partially offset by one-time lease termination costs recorded during the fourth quarter of 2023.

•FDIC assessment decreased $1.0 million, or 24.4%, from the prior quarter, driven primarily by the FDIC special assessment recognized by the Company.

•Other noninterest expense decreased by $1.2 million, or 4.6%, due primarily to decreases in consultant fees, advertising, and subscriptions, partially offset by increased card issuance costs.

The Company’s tax rate for the first quarter of 2024 increased to 23.56%, compared to 22.72% for the prior quarter, primarily due to changes in discrete items realized in both quarters.

ASSET QUALITY

The first quarter provision for credit losses was $5.0 million as compared to $5.5 million for the fourth quarter of 2023. Net charge-offs were minimal at $274,000 for the first quarter of 2024, or 0.01% of average loans annualized, versus $3.8 million, or 0.11% of average loans annualized, in the prior quarter, with the decline driven by negligible net charge-offs in the commercial real estate portfolio in the first quarter. Nonperforming loans increased slightly to $56.9 million, or 0.40% of total loans at March 31, 2024, as compared to $54.4 million, or 0.38% of total loans at December 31, 2023. Delinquencies as a percentage of total loans increased 8 basis points from the prior quarter to 0.52% at March 31, 2024.

The allowance for credit losses on total loans increased to $146.9 million at March 31, 2024 compared to $142.2 million at December 31, 2023, and represents 1.03% and 1.00% of total loans, at March 31, 2024 and December 31, 2023, respectively.

•higher than expected tax expense, including as a result of failure to comply with general tax laws and changes in tax laws;

•electronic or other fraudulent activity within the financial services industry, especially in the commercial banking sector;

•adverse changes in consumer spending and savings habits;

•the effect of laws and regulations regarding the financial services industry, including the need to invest in technology to meet heightened regulatory expectations or introduction of new requirements or expectations resulting in increased costs of compliance or required adjustments to strategy;

•operational risks related to cyber threats, attacks, intrusions, and fraud which could lead to interruptions or disruptions of the Company's operating systems, including systems that are customer facing, and adversely impact the Company's business; and

•any unexpected material adverse changes in the Company's operations or earnings.

The Company wishes to caution readers not to place undue reliance on any forward-looking statements as the Company’s business and its forward-looking statements involve substantial known and unknown risks and uncertainties described in the Company’s Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q ("Risk Factors"). Except as required by law, the Company disclaims any intent or obligation to 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, core net interest margin ("core margin"), 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 core margin to determine any items that may impact the net interest margin that may be one-time in nature or not reflective of its 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 a core margin 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, core 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.
