Magnite Inc (MGNI) shares surged 20.54% to close at $27.47, driven by strong third-quarter 2026 results and a significant raise in full-year guidance. The stock printed five fresh 52-week highs on November 5, 2026, as analysts upgraded their price targets following the earnings release.

What Happened

Magnite reported third-quarter 2026 financial results that highlighted a surge in connected TV advertising and a boom in political ad spending. The company raised its full-year 2026 contribution ex-TAC growth outlook to approximately 17% and increased its FY2026 contribution ex-TAC guidance from a range of $756.648M to $763.344M to a new figure of $783.400M. Management also signaled a 2027 adjusted EBITDA margin of at least 38.5%.

In response to the strong performance, several analysts raised their price targets. Susquehanna maintained its rating and lifted its target to $35 from $30. B. Riley raised its target to $32 from $30, while Lake Street increased its target to $29 from $25. Scotiabank also raised its price target, citing the strong earnings.

What The Data Shows

The stock opened at $24.88, a 9.2% gap up from the prior close of $22.79. The session high reached $28.17 at 9:45 AM ET, while the low was $24.88 at 7:05 AM ET. Volume stood at 1.7M shares, which is 0.7x the 3-month daily average. The company has a market cap of $3.2B, a P/E of 20.7, and a beta of 2.39. Revenue grew 8.3% on a trailing twelve-month basis, with a net margin of 22.5%. The 52-week range is $10.82 to $26.84.
