Isabella Bank Posts Record Net Income of $6.6 Million in Third Quarter
Key Facts
Isabella Bank Corporation reported record net income of $6.6 million, or $0.86 per diluted share, in the third quarter of 2026, compared with $5.2 million and $0.71 in the same period of 2025. The results came as net interest margin increased, while earnings included expenses related to the proposed acquisition of Grand River Commerce. Those expenses totaled $657,000 after tax, according to the company statement published by ACCESS Newswire. That puts the quarter’s performance in the context of two concurrent trends: improved interest income and deal costs incurred before completion. The deal is set to be the bank’s next expansion milestone, with closing expected on November 2, 2026.
Net interest margin rose to 3.71% in the third quarter, from 3.15% in the same quarter of 2025, according to Isabella Bank’s statement. The margin measures the net return from lending and investment activities against the cost of funding, and its improvement stands out alongside the increase in net interest income. Net interest income reached $19.4 million in the three months ended September 30, 2026, compared with $16.2 million in the same period a year earlier. The company said third-quarter 2026 net interest income was higher than a year before, alongside the wider margin. The comparison details one component of the improvement in record net income.
For the first nine months of the year, the bank reported net income of $16.6 million, or $2.24 per diluted share, compared with $14.2 million and $1.92 in the same period of 2025. The figures show that earnings growth was not limited to the third quarter, but extended to the year-to-date total. Comparing earnings per share also provides a view of performance after accounting for the effect of diluted shares, alongside a comparison of net income in dollars. The nine-month results remain distinct from the standalone quarterly figure, as they combine the performance of the three quarters ended September 30. That period’s total came as Isabella Bank prepared to complete its proposed acquisition of Grand River Commerce.
Isabella Bank said the regulatory and shareholder approvals required to complete the acquisition of Grand River Commerce had been obtained. The company expects to close the deal on November 2, 2026, subject to the satisfaction or waiver of customary closing conditions. The date follows results that showed $657,000 in after-tax acquisition-related expenses during the third quarter. Those expenses link the reported performance to the proposed deal, but do not change the fact that the bank posted record net income for the period. The next development centers on the expected closing, following completion of the required approvals, according to the company statement.
At Quanterix, the company said in an announcement dated October 28 that its third-quarter results call will be held on Monday, November 9, 2026, at 8:30 a.m. Eastern time. It said the financial results release will be issued before the call, and the webcast will be available through the event details page in the investor relations section. The announcement comes days before the company is due to present its results, giving investors a set time to follow the release and then the call. In its second-quarter results announced in August, Quanterix said revenue was $32.9 million and cash and marketable securities totaled $96.9 million. Its chief executive at the time added that revenue came in below the company’s expectations, attributing that to execution challenges and continued market weakness, and said the company was taking steps to improve commercial performance in the second half and beyond.
