Martsching Robert J, vice president and corporate controller at H.B. Fuller (FUL), has filed 42 Form 4 transactions with the SEC, all involving the single St. Paul, Minnesota-based adhesives manufacturer. The pattern is overwhelmingly one of compensation-driven activity rather than discretionary trading. Over the tracked period, Martsching has recorded zero open-market purchases and zero recent buys, while his only open-market sale came on July 10, 2025, when he disposed of FUL shares worth $613,851.71. That sale was paired with an option exercise the same day valued at $318,645.48, a common combination in which an executive converts vested options and sells a portion of the resulting shares.
The bulk of Martsching’s filings are mechanical in nature: grants (code A), option exercises (code M), and shares withheld to cover taxes (code F). His most recent activity, clustered in late January 2026, reflects this routine. On January 26, 2026, he received a grant valued at $378,178.63, alongside a smaller award of $1,021.19 two days earlier, and exercised options worth $10,572.32 and $11,713.65 on consecutive days. Tax-withholding transactions on January 24, 26, and 27 totaled roughly $17,224.27, a standard offset to the shares acquired through exercises and grants. A zero-value award on January 20, 2026, and another on January 26, 2026, round out the recent filings.
Across all 42 transactions, Martsching has acquired $919,550.34 in shares—almost entirely through option exercises and restricted stock grants—while selling $613,851.71. The absence of any open-market purchases or sales beyond the single July 2025 disposition suggests his trading is driven by the vesting and exercise schedule of his compensation package rather than a directional bet on FUL’s stock. The most recent filings, all in January 2026, show no new sales, only the recurring cycle of grants, exercises, and tax withholdings that typify a senior corporate officer’s Form 4 history.
