Mastin Celeste Beeks, President and CEO, has demonstrated a strong accumulation bias in their insider trading activity, with $31.4 million in total buys compared to just $1.7 million in sales across two companies—H.B. Fuller Company (FUL) and Granite Construction Incorporated (GVA). The overwhelming majority of transactions involve FUL, where Beeks has executed multiple large acquisitions, including an $8.0 million purchase on January 26, 2024, an $8.7 million acquisition on January 27, 2025, and a $12.1 million buy on January 26, 2026. These major acquisitions were supplemented by smaller periodic purchases, often in the hundreds of thousands, through transactions coded "F" (tax liability) and "M" (open market). The only significant sale occurred on November 24, 2025, when Beeks divested $801,259 worth of GVA shares.
Recent activity shows a continuation of this pattern, with Beeks making no new purchases in early 2026 but executing a $186,727 sale of FUL shares on January 27, 2026—the first outright sell transaction in the available data for this stock. Despite this minor divestment, the broader trend remains heavily skewed toward accumulation, particularly in FUL, where Beeks has consistently increased their position through both large block purchases and smaller periodic acquisitions. The absence of any material selling in FUL prior to 2026 suggests a long-term holding strategy, with the recent sale representing only a fractional reduction relative to the total position.
