ISBA ISABELLA BANK Corp Insider Trading

Director Bourland buys 6 shares of ISBA at $48.90; stock now $45.75, down 19.1% from 52-week high.

Director Jill Bourland purchased 6 shares of Isabella Bank Corp at $48.90 on April 16, 2026, a modest transaction increasing her holdings from 5,847 to 5,853 shares. The stock has since declined to $45.75, trading 19.1% below its 52-week high of $56.58, though it is up 1.7% over the prior 30 days and down 10.0% over 90 days. Bourland's cross-ticker track record shows strong historical performance with 20 prior buys averaging +13.0% at the 90-day mark and a 76.47% win rate, but her same-ticker history at ISBA is mixed: of five measurable 90-day outcomes, only one prior buy (August 2025) delivered a positive 90-day return (+28.1%), while another (January 2026) showed a negative return (-1.3%), suggesting inconsistent timing at this particular issuer. The company's fundamentals remain stable with $1.4M quarterly revenue, $5.2M net income, 5.0% annual revenue growth, and a reasonable P/E of 14.43, but the small share quantity and recent stock weakness offer limited catalyst signals.

Director Jill Bourland purchases 6 shares of ISABELLA BANK CORP at $44.03; holdings now 5,840 shares following pattern of 5 buys in 8 months.

Bourland's purchase of 6 shares at $44.03 on 2026-03-16 continues a consistent buying pattern at ISBA, with 5 prior buys in this stock over the past 8 months. While the share count is modest (net change +0.1% vs pre-transaction holdings), the transaction occurred as ISBA trades 20.5% below its 52-week high and has declined 12.3% in the past 30 days and 18.6% over 90 days—suggesting deliberate accumulation during a period of stock weakness. Her prior trades at ISBA show measurable positive returns: the 2025-08-18 and 2025-07-16 buys each returned +2.3% and +1.5% at the 30-day mark, with both ultimately delivering +28.1% and +16.3% at the 90-day mark, indicating her prior timing at this ticker has been sound. Set against her broader cross-ticker track record of 20 prior buys averaging +3.7% at 30 days and +13.3% at 90 days with an 82.35% win rate, this filing signals director-level conviction during a pullback in a bank with moderate fundamentals: $1.4M latest quarterly revenue, $5.2M net income, a P/E of 14.20, and 5.0% annual revenue growth.

President & CEO Schwind Jerome E buys 396 ISBA shares at $31.47; 4 of 5 prior buys produced positive 90d returns. Cluster pattern: 3 other insiders also bought within 14 days.

Schwind Jerome E, President & CEO of Isabella Bank Corp, purchased 396 shares at $31.47 on 2026-03-02, bringing his holdings to 37,493 shares. His track record at this ticker is notably strong: 4 of 5 prior buys at ISBA (spanning Jan–May 2025) delivered positive 90-day returns, with gains ranging from +9.1% to +34.5%. The current purchase comes at a price significantly below the 52-week high of $56.58, and notably, 3 other insiders also executed purchases within the prior 14 days, forming a cluster buy pattern. This convergence of repeated well-timed prior purchases by the CEO and contemporaneous buying by multiple insiders suggests synchronized confidence in the stock's value at current levels, though the stock is currently -15.5% from its 52-week high and the company trades at a P/E of 19.27.

Chief Credit Officer buys 103 ISBA shares at $31.47; 4 of 5 prior buys well-timed at 90d, cluster pattern detected (3 others bought within 14d)

Catlin Jon D, Chief Credit Officer of Isabella Bank Corp, purchased 103 shares at $31.47 on 2026-03-02, bringing his total holdings to 1,285 shares.

The current transaction occurs within a cluster pattern, as 3 other insiders also bought within the past 14 days, suggesting coordinated management confidence. The stock currently trades at $47.80, up 2.3% over the past 90 days and down 3.9% over 30 days, providing moderate context for interpreting this insider accumulation in a $350.6M market-cap financial institution with a P/E of 19.27.

CLO Michael Kyle Huenemann buys 61 ISBA shares at $31.47; cluster of 3 other insiders buying within 14 days

McDonnell Neil Michael, the company President, purchased 55 shares at $31.47 on 2026-03-02, a modest transaction adding 0.5% to his existing 12,133-share position.

His prior four purchases at ISABELLA BANK CORP have demonstrated disciplined timing, with 3 of 3 measurable prior buys yielding positive 90-day returns, including a +17.0% gain on his 2025-05-09 purchase. Against current context, the stock trades at $47.80, a -15.5% pullback from its 52-week high, though +2.3% over the trailing 90 days. The company's fundamentals remain solid with net income of $5,240,000.00, annual revenue growth of +5.0%, and a reasonable P/E of 19.27. The clustering of insider purchases across multiple executives, combined with McDonnell's established pattern of well-timed accumulation at this ticker, warrants investor attention.

Director Jill Bourland bought 5 shares of ISABELLA BANK CORP at $51.30; modest addition to 5,825-share position.

Director Jill Bourland purchased 5 shares of ISABELLA BANK CORP at $51.30 on 2026-02-17, increasing her holdings from 5,819 to 5,825 shares—a net addition of 5 shares (+0.1%). The transaction size is very small in absolute terms. However, Bourland's cross-ticker track record shows 20 prior buys with an average 90-day return of +12.4% and a 77.78% win rate, suggesting a history of favorable timing on open-market purchases. At ISABELLA BANK CORP specifically, her prior 3 measurable trades posted 90-day returns of +28.1%, +16.3%, and -1.7%, with 2 of 3 well-timed; the 30-day price performance is +2.0% since this purchase.

The minimal share count change makes this a marginal transaction, though Bourland's historical execution pattern may warrant observation of subsequent price behavior.

Director Opperman bought 277 ISBA shares at $49.58; 6 other insiders also bought within 14 days. Stock at $50.70, -10.4% from 52-week high.

Director Sarah R Opperman purchased 277 shares at $49.58 on 2026-01-20, adding 1.1% to her holdings of 24,412 shares. This buy occurs within a 14-day cluster in which 6 other insiders also bought, suggesting coordinated confidence rather than an isolated transaction. Opperman's prior buys at ISBA show mixed timing outcomes: 3 of 5 prior trades were well-timed at the 90-day mark, with her most recent ISBA purchase (2025-01-24) showing a 30-day return of -3.1% and a 90-day return of +0.1%. The current stock price of $50.70 is -10.4% from its 52-week high of $56.58, positioning the purchase in a region where the stock has declined 30 days but recovered 41.3% over 90 days. Fundamental metrics show the company is profitable (net income $5.2M, P/E 20.44, market cap $371.9M) with modest annual revenue growth of 5.0%. The multi-insider buy cluster and the company's stable financial position warrant attention, though Opperman's historical accuracy at ISBA remains moderately predictive rather than definitive.

McDonnell (ISBA President) buys 302 shares at $49.58; cluster of 6 other insiders bought in past 14 days; 90d track record at ticker is 3-for-3 well-timed buys

Neil Michael McDonnell, President, purchased 302 shares of Isabella Bank Corp at $49.58 on 2026-01-20, bringing holdings to 9,870 shares. This buy occurs within a cluster pattern: 6 other insiders also bought within the past 14 days, suggesting coordinated or correlated conviction at the current valuation.

Director Evans Jae A bought 201 shares of ISABELLA BANK CORP at $49.58; cluster of 6 other insiders buying within 14 days signals coordinated confidence.

Evans Jae A, a director, purchased 201 shares at $49.58 on 2026-01-20, increasing his holdings to 26,953 shares. This transaction is part of a broader cluster pattern: 6 other insiders also bought within the past 14 days at ISABELLA BANK CORP. Cluster buying by multiple insiders is typically noteworthy as it suggests collective assessment of valuation or opportunity. At the same-ticker level, Evans has a mixed track record: his prior buy on 2025-01-24 showed a 90-day return of +0.1%, while an earlier buy on 2024-01-29 returned -14.5% over 90 days—only 1 of 2 prior trades at this ticker was well-timed. The stock is currently trading at $50.70, down 3.1% over the past 30 days but up 41.3% over 90 days. Given the modest share addition (+0.8% of holdings), the P/E of 20.44, and the mixed timing history on prior same-ticker purchases, this filing should be monitored for whether the multi-insider buying pattern translates to sustained stock performance.
