Director Kelley buys 5,000 MDU shares at $20.84; holdings rise to 8,031 (+165.0%)

Director Charles M Kelley purchased 5,000 shares of MDU Resources at $20.84 on 2026-02-13, increasing his holdings from 3,031 to 8,031 shares—a 165.0% increase in position size. The transaction occurred at a price $0.57 above the current price of $20.27 and within 1.4% of the 52-week high of $21.33, suggesting the purchase was not executed at a clear valuation discount. MDU's fundamentals show significant headwinds: annual revenue contracted 62.2% year-over-year despite current quarterly revenue of $315.0M, while the P/E multiple of 24.42 sits elevated relative to historical norms for industrials. The substantial increase in Kelley's personal stake—from 3.0K to 8.0K shares—represents a material commitment, though the entry price and deteriorating growth trajectory warrant careful evaluation of the underlying investment thesis.

Significance 4/10

CFO Vollmer buys 5,000 shares of MDU at $16.08; holds 344.5K shares post-transaction amid -62.2% annual revenue decline.

Jason L. Vollmer, MDU's CFO, purchased 5,000 shares at $16.08 on September 8, 2025, increasing his holdings from 339.5K to 344.5K shares. This acquisition occurs within a context of significant headwinds: the company reports annual revenue growth of -62.2%, and the stock is trading at $16.06, down 20.3% from its 52-week high of $20.16. Vollmer's prior transaction at MDU (a buy on 2025-08-19) remains too recent to evaluate, and his cross-ticker track record shows only 1 prior buy with no timing data. The purchase represents a modest 1.5% increase to his existing stake and does not establish a pattern of accumulation or conviction given the limited transaction history available.

Significance 4/10

CFO Vollmer buys 5,000 shares of MDU at $16.28; stock down 18.6% from 52-week high and revenue fell 62.2% YoY

Jason L Vollmer, CFO of MDU Resources, purchased 5,000 shares at $16.28 on 2025-08-19, bringing his holdings to 339,548 shares. The transaction occurs against a backdrop of material headwinds: annual revenue has contracted 62.2%, the stock trades 18.6% below its 52-week high of $20.16, and has declined 3.6% over the prior 30 days. At $16.40 current price, the shares are trading only marginally above the transaction price. While the CFO's willingness to deploy $81,375.00 at current levels may reflect confidence in the business outlook, the significant revenue decline and persistent weakness in the share price suggest this purchase warrants contextual scrutiny regarding management's forward guidance and the drivers of the revenue contraction.

Significance 5/10

Director Dennis W Johnson bought 30,000 shares of MDU at $16.64, raising stake to 180,166 shares amid -33.2% annual revenue decline.

Director Dennis W Johnson purchased 30,000 shares (30.0K shares) at $16.64 on 2025-02-10, increasing his post-transaction holdings to 180,166 shares (180.2K shares), a 20.0% increase from pre-transaction levels. The purchase comes as the company faces material headwinds: MDU's annual revenue growth was -33.2%, and the stock is down 7.2% over 30 days and 8.6% over 90 days, trading at $16.46, which is 18.4% below its 52-week high of $20.16. While the company maintains modest profitability with net income of $64,615,000.00 ($64.6M) and a valuation multiple of 8.44 P/E, the director's accumulation of a significant share block during a period of revenue contraction and recent price weakness merits investor attention to understand the rationale and forward outlook.
