What this transaction means for investors

The options behind this sale were struck at $5.80, so with Magnite near $23, Barrett was converting a grant worth roughly $17 a share in profit, the kind of deep-in-the-money equity that dates back years. He exercised and sold under a plan he set in March, months before this week's earnings, so the timing that put the sale a day after a strong report was set well in advance. Plus, he kept more than 400,000 shares, so his stake is far from cleared.

The quarter he sold into was a good one, driven by the part of the business that matters most. Connected TV revenue, Magnite's growth engine, rose 36% to $97 million and now makes up more than half of the company's contribution, with adjusted earnings up 30%. Barrett said the company "significantly beat consensus expectations on both the top and bottom line." Magnite also raised its full-year outlook. The softer note sits in the rest of the business, since the mobile and desktop side grew just 2%, leaving Magnite increasingly dependent on connected TV to carry the whole story. But shares jumped nearly 20% after earnings, so investors are clearly still celebrating the quarter.
