FIBK FIRST INTERSTATE BANCSYSTEM INC Insider Trading

10% institutional holder divests substantial FIBK stake; stock trading near mid-range of recent range

Scott Jonathan R, a ten-percent beneficial owner, sold a material block of First Interstate BancSystem shares, reducing holdings by approximately six percent. This is a portfolio rebalancing decision by an institutional holder—not an insider trading signal—and should be interpreted through the lens of asset allocation rather than insider conviction about the company's prospects. The bank itself remains solidly profitable with reasonable valuation, so this exit reflects the fund's own capital management needs rather than concerns about FIBK's fundamentals. The stock is trading well below its recent highs but stable over the last quarter, providing a reasonable exit point for a holder looking to redeploy capital.

Director HEYNEMAN sells 35,000 FIBK shares across two days (Nov 10-11) for $1,123,300; reduces stake by 53.7% to 30,154 shares post-transaction.

HEYNEMAN JOHN M JR, a Director at FIRST INTERSTATE BANCSYSTEM INC, executed 2 separate sales totaling 35,000 shares for $1,123,300.00, with a blended average price of $32.09. The sale reduced his holdings from 65,154 shares to 30,154 shares—a 53.7% reduction in his pre-transaction stake. The current stock price of $32.45 is only 0.11% above the blended average transaction price of $32.09, meaning the director sold very close to current market levels. This substantial reduction in holdings warrants attention as it represents a material change in the Director's ownership position, though the lack of a scheduled trading plan flag or comparative track record data limits inference about the underlying motivation for the disposition.

Susan Heyneman Trust sold 55,000 shares of FIBK at $27.86 on 2025-08-01; currently trading at $28.41.

The trust sold 55,000 shares (529.3K shares post-transaction, down 9.4% from 584.3K pre-transaction holdings) at $27.86 per share for $1.5M. The stock has since risen to $28.41, 1.9% above the sale price, and remains 19.9% below its 52-week high of $35.47. This transaction follows a prior sale by the same insider on 2025-07-14; however, timing outcomes for that earlier trade are not yet measurable. With a modest P/E of 13.66 and stable fundamentals (net income of $50.2M), the company does not exhibit distress signals. The sale represents a proportional reduction in the trust's stake rather than an emergency liquidation, and the near-term price action has not validated or contradicted the timing of the sale.

10% owner sold 55.0K FIBK shares at $31.11 ($1.7M); remains 584.3K holder post-sale

Susan Scott Heyneman Trust sold 55,000 shares at $31.11, reducing holdings from 639.3K to 584.3K shares (-8.6% of prior position). The transaction occurred at a price 3.7% above the current market price of $29.99, which is down 15.4% from the 52-week high of $35.47 but up 12.4% over the past 30 days and 15.4% over 90 days. FIBK trades at a P/E of 14.42 with net income of $50.2M and a $3.1B market cap. The sale reflects a meaningful reduction in the largest insider stake, though the trustee retains a substantial holding and the transaction occurred within the stock's recent uptrend.

10% Owner Scott Julie A sells 42,270 shares in 2 transactions ($1.4M) at blended avg $33.31; holds 613,019 shares post-sale.

Scott Julie A, a 10% owner, executed 2 separate sales totaling 42,270 shares for $1,408,101.60, reducing holdings by 6.5% to 613,019 shares. The sales occurred on 2024-11-08 and 2024-11-12 at prices of $32.78 and $33.80, near the stock's 52-week high of $34.45. Across the insider's 5 prior trades at FIBK, none were well-timed at the 90-day mark (average post-sale returns: 30-day +8.2%, 90-day +8.6%), and the current stock is trading at $33.74, up 9.6% over 30 days and 20.0% over 90 days from the sale dates—suggesting the recent sales fell in advance of continued strength rather than ahead of a decline. The company's P/E of 15.00 and $3.5B market cap reflect a moderately valued mid-cap financial institution.

CEO Riley Kevin P bought 11.2K shares for $347.7K while selling 7.3K shares for $217.6K on FIBK (net 3,932 shares purchased).

Kevin P Riley, President & CEO of First Interstate BancSystem, executed 8 separate purchases totaling 11,232 shares for $347,718.42 against 1 sale of 7,300 shares for $217,613.00 on July 31–August 1, 2024, resulting in a net purchase of 3,932 shares. The buy prices ranged from $29.88 to $31.62, while the sale occurred at $29.81, indicating the CEO was acquiring shares near the top of the 52-week trading range ($21.68–$32.35). His prior open-market buy history at this ticker shows a 0% win rate at the 90-day mark, with all three prior purchases (June 2023) showing negative 90-day returns between -3.8% and -4.8%, and his cross-ticker track record reveals an average 90-day return of -3.1% with a 0% win rate. The current stock price of $28.77 is now -11.1% from the 52-week high, reflecting post-transaction price action that aligns with his historically poor timing pattern.
