Magnite (MGNI): Evaluating Valuation After Landmark Acxiom Integration and Recent Stock Surge

If you have been watching Magnite (MGNI), this week’s headlines might have stopped you in your tracks. The company just announced a significant integration with Acxiom, making it Acxiom’s first programmatic partner for sell-side data activation. This move gives advertisers a streamlined way to activate both first-party and Acxiom’s third-party data directly within Magnite’s platform. The partnership promises reduced costs and additional efficiency, as well as access to enhanced forecasting and better match rates. These features could raise Magnite’s profile with advertisers and data partners alike. This news comes at a time when Magnite’s stock has been quietly but steadily gaining ground. Shares have jumped 7% in a single day, extending their month-long run to 3% and delivering a 57% return in the past three months. Over the past year, the stock has almost doubled, benefitting from healthy ad spending and an industry-wide pivot toward connected TV. Still, volatile trading earlier in the year and a pause in management guidance introduced some uncertainty, even as Magnite’s reach and supply coverage remain market-leading. After a strong rally and with this partnership now in play, the real question is whether Magnite is trading below its true value or if the recent surge reflects all the growth markets expect to see. What do you think?
