LARSON MICHAEL
LARSON MICHAEL is a corporate insider at REPUBLIC SERVICES, INC. (RSG) filing SEC Form 4 transactions. 218 transactions across 5 companies, totaling $434,450 in purchases and $0 in sales. Source: SEC EDGAR.
Across his recent activity at Republic Services and Ecolab, the single disposition in Michael Larson's record is a 921-share Ecolab tax withholding on March 4, 2025, priced at $269.173 — not an open-market sale, just the mechanical byproduct of an option exercise. Nothing else in his recent record looks like selling: Republic Services shows zero shares ever bought or sold outside of grants across 104 transactions, and Ecolab's lifetime total sell count (5,250 shares) sits almost entirely outside this recent window. On the buy side, Larson holds real, if sparse, purchase-only positions: 3,000 AutoNation shares (2010-2018, no sales), and two Western Asset closed-end funds — 22,000 shares and 14,000 shares respectively — bought across just three transactions each between 2005 and 2023, with zero shares sold from either.
