(NASDAQ:MTSI), reported a single transaction in Table I involving common stock. On October 28, 2026, 241 shares were disposed of under transaction code "F," at a per-share price of $260.92.

The filing's footnote states that the shares were "withheld by the Issuer to satisfy the Reporting Person's tax withholding obligations in connection with the vesting of restricted stock units on October 28, 2026."
