Sale Details
Sciammas Maurice, EVP of Worldwide Sales & Marketing, sold 15,000 shares of MPWR (Monolithic Power Systems) on the open market on July 15, 2026, at a price of $1,349.73 per share for a total transaction value of $20,245,937. The sale was disclosed via a Form 4 filing with the U.S. SEC on July 17, 2026, representing 0.031% of MPWR’s $64.5 billion current market capitalization.
Supply Signal Context
As a core business executive leading the company’s global sales and marketing operations, this single-block sale exceeds $20 million in value. While not a routine small-scale transaction, the sale represents less than 0.04% of the company’s total market cap, placing it in the category of routine personal financial planning dispositions, rather than a material control shift or operational signal.
Cross-Reference Check
On July 17, 2026, the same executive filed 10 additional Form 4 disclosures for separate open-market sales, totaling approximately 18,000 additional shares with a combined value of over $17 million, with per-share prices ranging from $1,314.03 to $1,359.36. This confirms concentrated insider selling activity from Maurice in mid-July 2026. Separately, as of December 31, 2025, MPWR had 1,084 institutional holders (a 72-quarter-over-quarter increase), with institutions holding 99.7% of the company’s float, indicating a stable institutional ownership base.
Signal Limits & Follow-Up Markers
This Form 4 disclosure does not specify whether the sale was executed under a pre-arranged 10b5-1 plan, and does not provide insight into the executive’s personal valuation of MPWR shares or short-term price expectations. Follow-up items to monitor include any future insider trading filings from Maurice, MPWR’s Q2 2026 earnings report scheduled for July 30, 2026, and changes to institutional holding positions.
