Financial Performance ISABELLA BANK CORP achieved strong financial results for the year ended December 31, 2025:

• Net Income: $18 million, an increase of 5.9% from $17 million in 2024.
• Earnings Per Share (EPS): $3.60, up from $3.40 the previous year.
• Total Revenue: Reached $75 million, a 4.2% increase from $72 million in 2024. This growth was primarily due to a healthy Net Interest Margin (NIM) of 3.5%, slightly up from 3.4% in 2024, reflecting the rising interest rate environment.

The bank's total loan portfolio expanded modestly by 1.4%, reaching $1.465 billion (from $1.445 billion in 2024). A solid increase in customer deposits, which grew to $1.6 billion in 2025 (from $1.55 billion in 2024), supported this growth and demonstrated continued customer trust and a stable funding base. ISABELLA BANK CORP also reported a Return on Assets (ROA) of 1.0% and a Return on Equity (ROE) of 9.1% for 2025. The bank maintained its commitment to shareholders, declaring an annual dividend of $1.20 per share for 2025, consistent with the prior year.

Risk Factors While ISABELLA BANK CORP delivered solid performance, investors should consider several potential risks:

• Loan Quality: A slight, though currently minor, increase in past-due loans requires ongoing attention.
• Economic Conditions: Broader economic uncertainties, such as potential recessions or sustained high inflation, could affect loan demand and the quality of assets.
• Interest Rate Fluctuations: While rising rates have improved Net Interest Margin (NIM), a rapid reversal could squeeze margins if the cost of deposits increases faster than loan yields.
• Regulatory and Operational Challenges: New capital requirements, consumer protection laws, and growing cybersecurity threats present continuous challenges to the bank's operations and financial results.

Management Discussion Management reported a year of steady, measured growth, attributing strong financial performance to an improved Net Interest Margin in a rising rate environment. They noted a strategic shift in the loan portfolio composition:

• Consumer loans: Decreased strategically by 9.1%, from $165 million in 2024 to $150 million in 2025. This deliberate reduction aims to manage risk in a potentially volatile economic climate.
• Commercial Real Estate (CRE) loans: Grew to $670 million.
• Residential Mortgages: Grew to $350 million.
• Commercial & Industrial (C&I) loans: Grew to $190 million.
• Agricultural loans: Grew to $100 million.

These increases indicate a continued focus on stable and diversified segments. Management emphasized the strong quality of the loan book, with past-due loans remaining very low at 0.32% of the total portfolio, reflecting sound underwriting practices.

Financial Health ISABELLA BANK CORP demonstrates robust financial health, marked by strong capital and sound asset quality. The bank's capital ratios are well above regulatory minimums:

• Common Equity Tier 1 (CET1) ratio: 11.5% (up from 11.2% in 2024).
• Total Capital Ratio: 13.8% (up from 13.5% in 2024).

These strong capital levels provide a solid buffer against potential losses and support future growth. The bank also maintains a strong liquidity position, bolstered by a stable and growing customer deposit base, which reached $1.6 billion in 2025. Debt securities remained stable at $300 million, further enhancing liquidity. Asset quality remains strong, with past-due loans increasing only slightly to $4.74 million in 2025 (a 2.3% rise from $4.63 million in 2024), representing a low 0.32% of the total loan portfolio.

Future Outlook ISABELLA BANK CORP plans a strategy of cautious, diversified growth, prioritizing asset quality and capital strength. The reduction in consumer loans reflects a proactive approach to risk management, anticipating potential economic shifts. The bank's strong capital position and stable deposit base provide a solid foundation to navigate economic challenges and seize opportunities within its local markets. Management anticipates continued prudent lending, a healthy balance sheet, and consistent shareholder returns in the coming year, alongside exploring organic growth opportunities in core business segments.
