Matthew Sanderson, Executive Vice President at an undisclosed company, has demonstrated a consistent pattern of selling activity in shares of Tetra Technologies (TTI) over the past several years, with no recorded purchases. According to SEC Form 4 filings, Sanderson executed 33 transactions totaling over $1.02 million in sales, all involving TTI stock. His most recent sales occurred in early 2026, including a $313,650 transaction on March 14 and a $111,930 sale on February 28. Earlier in February 2026, he sold smaller blocks of shares totaling approximately $159,335 across two transactions on the 25th.
Sanderson’s selling activity extends back to at least 2024, with notable transactions including a $107,572 sale in March of that year and multiple mid-five-figure disposals in 2025, such as a $55,477 transaction on February 19. The filings indicate these sales were primarily executed under Rule 144 (code F), suggesting they may involve the liquidation of restricted or control shares. While Sanderson has not reported any open-market purchases, the absence of recent transactions in 2026 beyond March suggests a potential pause in his selling activity. The data reflects a clear divestment trend concentrated solely in TTI, with no diversification into other securities.
