Theodore Blegen, EVP and CFO of Monolithic Power Systems (MPWR), has demonstrated a consistent pattern of selling company shares, with no recorded purchases across 71 reported transactions. His total sell activity exceeds $100 million, with a concentrated wave of disposals in early 2026. On February 6, 2026, Blegen offloaded shares worth $25.4 million—his single largest transaction—followed by a series of smaller sales totaling approximately $2.3 million on February 2, including individual transactions ranging from $44,684 to $429,585. This follows a similar cluster of sales on January 2, 2026, where he disposed of shares worth over $2.1 million across multiple filings, with individual transactions as high as $613,827. Earlier, on December 1, 2025, he executed two sales totaling $1.8 million. The absence of any buy transactions suggests a one-sided disposition toward reducing his stake in MPWR, though the sales appear structured rather than abrupt, with a mix of large block transactions and smaller, incremental disposals. The timing of these transactions—particularly the February 2026 activity—indicates an acceleration in selling volume compared to prior months. All sales relate exclusively to MPWR, reflecting his singular focus on divesting holdings in his employer’s stock.
