Nathan B. Theurer, Vice President - Global Controller and Chief Accounting Officer at First Solar, Inc. (FSLR), has demonstrated a consistent pattern of selling activity in the company’s stock, with no recorded purchases across 28 reported transactions. Since August 2025, Theurer has sold shares totaling $318,176.64, with the largest single transaction occurring on August 14, 2025, when he disposed of $124,872.58 worth of stock. More recently, his sales have accelerated in March 2026, with multiple transactions including a $63,406.80 sale on March 10 and a $19,154.88 sale on March 17. Smaller but frequent sales, such as four separate dispositions on March 9 ranging from $5,139.72 to $10,469.80, suggest a methodical reduction in holdings. Theurer’s activity is exclusively tied to First Solar, with no trades in other companies, and his filings include several non-sale transactions marked as acquisitions (code "A"), dispositions following the exercise of derivative securities (code "M"), and gifts (code "F"). The absence of any buying activity and the repeated divestments indicate a clear directional bias toward reducing his stake in FSLR over time.
