RIBAR GEOFFREY G 4

What Happened
Geoffrey G. Ribar, a director of MACOM Technology Solutions Holdings, Inc. (MTSI), received a grant of 776 restricted stock units (RSUs) on March 6, 2026. The grant was recorded as an acquisition with an acquisition price of $0.00 (i.e., an award of RSUs rather than an open-market purchase). The RSUs represent the contingent right to receive 776 shares of common stock and vest in full on March 6, 2027, provided Ribar remains in continuous service through that date.

Context
RSU grants to directors are common as part of compensation and do not represent an open-market purchase (which some investors view as a stronger bullish signal). This grant is a deferred equity award that converts to common shares only if vesting conditions are met (service through 3/6/2027). Check the full Form 4 for any additional disclosures (total holdings, tax withholding instructions, or timeliness notes).
