Tappin Matthew, President of Asset Management, has demonstrated a consistent pattern of selling shares in Stem, Inc. (STEM) over the past two years, with no recorded purchases in SEC filings. His transactions total $508,913 in sales across 30 filings, with the most recent activity concentrated in March 2026. The largest single sale occurred on November 11, 2025, when he disposed of shares worth $169,637, followed by another significant sale of $98,950 the previous day. Earlier transactions in 2024 included multiple sales in the $5,000–$54,000 range, such as a $54,529 sale on March 8, 2024, and a $48,485 transaction on March 19, 2024.
Recent activity shows continued divestment, though in smaller increments. Between March 3 and March 11, 2026, Matthew executed four sales totaling $16,388, with individual transactions ranging from $1,850 to $7,284. The filings also include several transactions coded as "M" (exercise of derivative security) and "A" (award or grant), though these did not involve monetary exchanges. The absence of any buy transactions suggests a sustained reduction in his STEM holdings, with the most recent sales reinforcing this trend. The data reflects a clear directional bias toward liquidation rather than accumulation of shares in the energy storage company.
