Isabella Bank Corporation reported stronger first quarter 2026 results, with net income of $5.0 million, or $0.68 per diluted share, up from $3.9 million, or $0.53, a year earlier. Management highlighted 26% earnings growth, supported by higher net interest income and fee-based revenue.

Loans reached $1.6 billion, with adjusted loans excluding mortgage broker advances up $27.2 million from year-end 2025, while total deposits rose $40.2 million to $1.9 billion. Net interest margin improved to 3.33% from 3.06% as loan and securities yields increased and funding costs eased.

Credit quality metrics stayed favorable, with nonperforming loans at 0.28% of total loans and allowance for credit losses at 0.90% of loans. Noninterest income climbed to $4.4 million from $3.5 million, though noninterest expenses increased to $14.7 million, raising the efficiency ratio to 68.50%.

Positive

  • Strong earnings growth: Q1 2026 net income rose to $5.0 million, a 26% increase over Q1 2025, with EPS improving to $0.68 from $0.53 and net interest margin expanding to 3.33% from 3.06%, supported by higher loan balances and solid fee income.
  • Healthy credit and capital: Nonperforming loans were only 0.28% of total loans, allowance for credit losses was 0.90% of loans, and key capital ratios such as common equity tier 1 at 11.71% and total risk-based capital at 14.01% indicate a robust capital position.

Negative

  • Rising operating costs: Noninterest expenses increased to $14.7 million from $13.3 million a year earlier, and the efficiency ratio, while improved versus some prior quarters, remained relatively elevated at 68.50%, reflecting higher compensation, benefits, and professional services spending.

net interest margin financial
"Net interest margin ("NIM") improved to 3.33%, up from 3.06% in first quarter 2025."
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") was $14.0 million at March 31, 2026, an increase of $287,000..."
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.
tangible book value per share financial
"Tangible book value per share (non-GAAP) was $25.32 as of March 31, 2026, compared to $25.01..."
Tangible book value per share is the company's total physical and financial assets minus its liabilities and intangible items (like goodwill and brand value), divided by the number of outstanding shares. It gives investors a conservative, per‑share estimate of what would remain if the business sold only its hard assets and paid its debts—useful for judging whether a stock is priced above or below its underlying, tangible worth, like valuing a property by its bricks and cash rather than its reputation.
nonperforming loans financial
"Credit quality remained strong, with a ratio of nonperforming loans to total loans of 0.28% at March 31, 2026."
Nonperforming loans are loans on which borrowers have stopped making the scheduled interest or principal payments for an extended period (commonly 90 days or more) or are otherwise in serious danger of default. Think of them as IOUs that aren’t being repaid: they tie up a lender’s money, reduce future interest income, and force the lender to hold extra reserves or take losses. For investors, a rising share of nonperforming loans signals weakening credit quality, higher potential losses, and greater risk to a bank’s profitability and capital.
efficiency ratio financial
"Efficiency ratio (2) | 68.50% | | 65.02% | | 67.62% | | 72.14% | | 72.39% |"
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.

Isabella Bank Corporation Reports Strong First Quarter 2026 Earnings
MT. PLEASANT, MICHIGAN — April 23, 2026 — Isabella Bank Corporation (Nasdaq: ISBA) (“Isabella” or the “Company”) reported net income of $5.0 million, or $0.68 per diluted share, for the first quarter 2026 compared to $3.9 million, or $0.53 per diluted share, for the first quarter 2025.
FIRST QUARTER 2026 HIGHLIGHTS
Loans, excluding advances to mortgage brokers, grew $27.2 million
Total deposits increased $40.2 million
Net income grew 26% compared to first quarter 2025
Net interest margin ("NIM") improved to 3.33%, up from 3.06% in first quarter 2025
Credit quality remained strong, with a ratio of nonperforming loans to total loans of 0.28% at March 31, 2026
“Isabella Bank Corporation delivered strong results in the first quarter, driven by loan and deposit growth across our markets," said CEO Jerome Schwind. "Initiatives implemented over the past year continue to drive noninterest income. Our initiatives this year remain focused on our commitment to provide products and services that attract new customers while continuing to fully support our current customers," he added.
"We are pleased with our stock performance after uplisting to the Nasdaq in May 2025. As expected, the lift in both volume and price has carried into 2026," Schwind added.
FINANCIAL CONDITION
Total assets were $2.3 billion as of March 31, 2026, an increase of $42.5 million compared to December 31, 2025, primarily due to increases of $23.1 million in interest bearing cash and $22.6 million in loans.
Available-for-sale (“AFS”) securities at fair value were $492.7 million as of March 31, 2026, a decrease of $5.0 million compared to December 31, 2025. The decrease during the quarter was largely driven by maturities and principal paydowns totaling $53.1 million, which were offset by purchases of $48.9 million. Net unrealized losses on AFS securities were $10.6 million as of March 31, 2026, compared to $9.9 million at December 31, 2025. Net unrealized losses as a percentage of the amortized cost of AFS securities were consistent compared to December 31, 2025, at 2%.
Loans were $1.6 billion as of March 31, 2026, an increase of $22.6 million compared to December 31, 2025. Adjusted loans (non-GAAP), which exclude advances to mortgage brokers, increased by $27.2 million from year-end 2025. Advances to mortgage brokers decreased by $4.6 million in first quarter 2026 due to decreased participation demand from the counterparty.
In first quarter 2026, the commercial real estate and residential mortgage portfolios increased by $20.9 million and $10.5 million, respectively. Most residential originations were adjustable-rate products, which are retained on the balance sheet rather than sold in the secondary market. The consumer loan portfolio continued to decline in 2026 amid decreasing demand, competition, and adherence to credit quality standards.
The allowance for credit losses ("ACL") was $14.0 million at March 31, 2026, an increase of $287,000 from December 31, 2025. The increase is due to loan growth and an increase in loss rates driven by loans charged off during the quarter. Nonaccrual loans were $4.4 million as of March 31, 2026 compared to $4.6 million at



December 31, 2025. Past due and accruing accounts between 30 to 89 days as a percentage of loans was 0.37% at March 31, 2026, compared to 0.44% at December 31, 2025. The Company believes its credit quality remains strong.
Total deposits were $1.9 billion at March 31, 2026, an increase of $40.2 million from December 31, 2025. The growth was driven in part by new customer relationships and included a $40.9 million increase in money market accounts and a $20.3 million increase in savings deposits. The growth was offset by a $15.1 million decrease in noninterest bearing deposits and a $3.7 million decrease in certificates of deposit.
Total equity was $234.0 million, or $31.90 per share, at March 31, 2026 compared to $231.4 million, or $31.60 per share, at December 31, 2025. Tangible book value per share (non-GAAP) was $25.32 as of March 31, 2026, compared to $25.01 as of December 31, 2025. Net unrealized losses in the AFS securities portfolio reduced tangible book value per share by $1.17 and $1.09 for the respective periods. Share repurchases totaled 8,062 during 2026 at an average price of approximately $49.86 per share.
RESULTS OF OPERATIONS
Net income in first quarter 2026 was $5.0 million, or $0.68 per diluted share, compared with $3.9 million, or $0.53 per diluted share, in first quarter 2025.
Net interest income was $16.9 million in first quarter 2026 compared to $14.5 million in first quarter 2025, representing 3.33% and 3.06% of earning assets, or NIM, respectively. The book yield from securities was 2.52% and 2.20% during the first quarters of 2026 and 2025, respectively. The yield on loans increased to 5.78% in first quarter 2026 from 5.71% in first quarter 2025. The increase in loan yields was primarily due to higher rates on new loans and variable rate commercial loans that continue to reprice. The cost of interest-bearing liabilities in first quarter 2026 decreased to 2.14% from 2.26% in first quarter 2025 primarily due to lower rates on the money market and certificate of deposit products.
The provision for credit losses in first quarter 2026 was $604,000, which reflects a $287,000 increase in the ACL on loans, net charge offs totaling $253,000, and an increase in the reserve for unfunded commitments. The provision for credit losses in first quarter 2025 was a credit of $107,000 due to the change in allowance for credit losses on loans and $52,000 in net recoveries, offset by an increase in the reserve for unfunded commitments.
Noninterest income was $4.4 million in first quarter 2026 compared to $3.5 million in first quarter 2025. Service charges and fees increased $398,000 compared to first quarter 2025, mostly due to initiatives to align our fees with the market. Wealth management fees grew $129,000 compared to first quarter 2025 due to the growth in assets under management since first quarter 2025. Earnings on bank-owned life insurance (“BOLI”) policies increased $76,000 compared to first quarter 2025 due to new investments in a separate account BOLI in 2025. Other noninterest income in first quarter 2026 included a $131,000 gain related to a death benefit from a BOLI policy.
Noninterest expenses were $14.7 million in first quarter 2026 compared to $13.3 million in first quarter 2025. Compensation and benefit expenses increased $545,000, reflecting annual merit increases, incentives, and higher medical insurance claims compared to first quarter 2025. Other professional services increased $304,000 as a result of costs related to profitability initiatives and product implementation costs.
Income tax expense was $985,000 in first quarter 2026, compared to $912,000 in first quarter 2025. The effective tax rate (ETR) was 16% and 19% for the first quarters of 2026 and 2025, respectively. The ETR in first quarter 2025 included a one-time tax expense totaling $166,000 due to the taxes owed from the lifetime earnings on BOLI policies that were surrendered during first quarter 2025. Excluding the one-time charge, the ETR was 15% for the first three months of 2025.

We intend such forward looking statements to be covered by the safe harbor provisions for forward looking statements contained in the Private Securities Litigation Reform Act of 1995, and are included in this statement for purposes of these safe harbor provisions. Forward-looking statements generally relate to losses, impact of events, financial condition, plans, objectives, outlook for earnings, revenues, expenses, capital and liquidity levels and ratios, asset levels, asset quality, financial position, and other matters regarding or affecting the Company and its future business and operations.

Factors that could cause such differences include, but are not limited to: (i) the impact on us or our customers of a decline in general economic conditions, and any regulatory responses thereto; (ii) slower economic growth rates or potential recession in the United States and our market areas; (iii) uncertainty or perceived instability in the banking industry as a whole; (iv) increased competition for deposits among traditional and nontraditional financial services companies, and related changes in deposit customer behavior; (v) the impact of changes in market interest rates, whether due to a continuation of the elevated interest rate environment or further reductions in interest rates and a resulting decline in net interest income; (vi) the lingering inflationary pressures, and the risk of the resurgence of elevated levels of inflation, in the United States and our market areas; (vii) the uncertain impacts of ongoing quantitative tightening and current and future monetary policies of the Board of Governors of the Federal Reserve System; (viii) changes in unemployment rates in the United States and our market areas; (ix) adverse changes in customer spending, borrowing and savings habits; (x) declines in commercial real estate values and prices; (xi) a deterioration of the credit rating for the United States long-term sovereign debt or the impact of uncertain or changing political conditions, including federal government shutdowns and uncertainty regarding United States fiscal debt, deficit and budget matters; (xii) cyber incidents or other failures, disruptions or breaches of our operational or security systems or infrastructure, or those of our third-party vendors or other service providers, including as a result of cyber-attacks; (xiii) severe weather, natural disasters, acts of war or terrorism, geopolitical instability, domestic civil unrest or other external events, including as a result of the policies of the current U.S. presidential administration or Congress; (xiv) in the impact of tariffs, sanctions and other trade policies of the United States and its global trading counterparts and the resulting impact on the Company and its customers; (xv) competition and market expansion opportunities; (xvi) changes in non-interest expenditures or in the anticipated benefits of such expenditures; (xvii) changes in accounting principles and standards, including those related to loan loss recognition under the current expected credit loss, or CECL, methodology; (xviii) the receipt of required regulatory approvals; (xix) changes in tax laws; (xx) the risks related to the development, implementation, use and management of emerging technologies, including artificial intelligence and machine learnings; (xxi) potential costs related to the impacts of climate change; (xxii) current or future litigation, regulatory examinations or other legal and/or regulatory actions; and (xxiii) changes in applicable laws and regulations. These forward-looking statements are based on current information and/or management’s good faith belief as to future events.

Non-GAAP Financial Measures
Some of the financial measures included in this press release are not measures of financial performance recognized in accordance with generally accepted accounting principles in the United States (“GAAP”). The Company believes these non-GAAP financial measures provide both management and investors with a more complete understanding of the Company’s financial position and performance. These non-GAAP financial measures are supplemental and are not a substitute for any analysis based on GAAP financial measures.
We classify a financial measure as being a non-GAAP financial measure if that financial measure excludes or includes amounts, or is subject to adjustments that have the effect of excluding or including amounts, that are included or excluded, as the case may be, in the most directly comparable measure calculated and presented in accordance with GAAP as in effect from time to time in the United States in our statements of income, balance sheets or statements of cash flows. Not all companies use the same calculation of these measures; therefore, this presentation may not be comparable to other similarly titled measures as presented by other companies.
A reconciliation of non-GAAP financial measures to GAAP financial measures is provided at the end of this press release.
