Roberts Johanna, EVP, General Counsel & Secretary, has demonstrated a consistent pattern of selling activity in Penumbra, Inc. (PEN) shares, with no recorded purchases across 55 transactions totaling $2.34 million in sales. Recent filings show a concentration of disposals in late 2025 and early 2026, including 17 sales since October 2025. The largest single transaction occurred on November 25, 2025, when Johanna sold shares worth $540,108, followed by a $349,340 disposition on December 15, 2025. Smaller but repeated sales clustered around key dates—notably eight transactions on December 1, 2025, totaling approximately $180,000, and seven sales on November 10, 2025, amounting to roughly $160,000. The activity includes periodic stock awards (coded "A") with zero reported value and automatic sales to cover tax obligations (coded "F"), such as the $163,543 transaction on February 15, 2026, and $62,529 on March 15, 2026. This pattern suggests Johanna has systematically reduced PEN holdings through both discretionary sales and mandatory transactions, with no offsetting acquisitions over the observed period. The transactions reflect an exclusive focus on one company, with all activity tied to Penumbra equity compensation.
