By ATTN Desk · Editorial oversight: Sean Han
On February 10, Michael Sing, CEO of U.S. power-semiconductor manufacturer Monolithic Power Systems, Inc. (NASDAQ: MPWR), sold approximately 34,000 shares of the company’s common stock under a predetermined Rule 10b5-1 trading plan, generating about $38.9 million in proceeds (roughly KRW 50 billion).
Earlier, on February 2, CFO Theodore Blegen similarly disposed of several thousand shares, raising around $3.12 million (approximately KRW 4 billion). Regulatory filings show that despite these sales, both executives continue to hold significant equity stakes.
According to the same filing, even after the sale, CEO Sing’s direct and indirect holdings remain valued at more than $1.1 billion (about KRW 1.5 trillion), based on the reported sale price.
In an 8-K filing and accompanying press release, the company announced that fourth-quarter 2025 revenue rose over 20% year-over-year to approximately $750 million. It also declared a 28% increase in its quarterly cash dividend, raising it from $1.56 to $2.00 per share, with the dividend payable on April 15 to shareholders of record as of March 31.
The announcement further disclosed CFO Blegen’s plan to retire and named Corporate Controller Rob Dean as interim CFO. Following the dividend increase and leadership change news, MPWR’s share price gained roughly 5% in the short term, drawing notable market attention.
