Assessing Magnite (MGNI) Valuation After Recent Share Price Correction

Magnite (MGNI) has caught investors' attention lately as its stock performance diverges from broader sector trends. Over the past month, shares have dropped by 27%. This has prompted questions about the factors shaping sentiment around this US-based ad tech company.

See our latest analysis for Magnite.

While Magnite's 1-month share price return of -27% has caught many off guard, it is worth noting that this comes after a strong push earlier in the year. Despite the recent correction, the 1-year total shareholder return still sits at an impressive 41%, and investors who have held for three years have seen even larger gains. Short-term momentum is fading for now, as sentiment seems to have shifted, but long-term performance remains robust in the broader context.

Most Popular Narrative: 37.9% Undervalued

According to the most widely followed narrative, Magnite’s fair value sits significantly above its recent closing price, suggesting the market may be missing a major opportunity hidden in plain sight.

Magnite is positioned to benefit from the accelerating shift of ad spend from traditional TV to digital and connected TV (CTV) platforms, as evidenced by deepened partnerships with top streamers (Roku, Netflix, LG, Warner Bros. Discovery, Paramount) and expanding SMB participation in CTV. This shift is expected to drive sustained revenue growth and result in a higher-margin business mix.

Another View: Earnings Multiple Poses Caution

While Magnite appears deeply undervalued by some fair value estimates, its current price-to-earnings ratio of 57.8x is much higher than the US Media industry average of 18.8x and a fair ratio of 29.1x. This sharp gap signals valuation risk that could limit upside if market optimism fades. Does this make Magnite a value trap or a hidden gem?
