Multiple Magnite insiders sold shares under pre-set plans as CTV revenue rose 36%

Several Magnite insiders sold company stock on the same day under pre-arranged Rule 10b5-1 trading plans, according to reports drawn from the ad-tech company's filings. The chief executive exercised 293,968 options at a strike price of $5.80 and sold the shares at $22.72 each under a plan adopted in March. Another insider, Evans, retained 496,840 shares valued at about $12.08 million after selling under a plan established in August 2025. Other filings describe insiders retaining 315,805 shares (about $7.68 million) and 260,836 shares (about $6.34 million) after sales tied to plans dated September 2025 and December 2025. The sales followed a quarter in which Magnite reported 36% growth in connected-TV revenue. Over the same period the company repurchased about $28 million of its own stock. Rule 10b5-1 plans are scheduled in advance and are generally used by executives to sell on a fixed timetable, limiting the inference that can be drawn from the timing of individual transactions.
