Listen to the news

Magnite (MGNI) is back in focus after LG Ad Solutions extended their connected TV partnership for three years, keeping SpringServe as LG’s exclusive CTV video ad server across major global regions.

The LG renewal comes at a time when Magnite’s share price has cooled in the very short term, with a 1 day share price return of down 4.53% and a 7 day share price return of down 7.99%. However, the 90 day share price return of 23.19% and year to date share price return of 45.52% indicate momentum over recent months.

Magnite has already delivered a sharp move over the past quarter, and the LG Ad Solutions renewal and recent debt repricing reset the story. Is the bigger upside still ahead, or has most of it already been priced in?

Most Popular Narrative: 21% Undervalued

Magnite’s most followed narrative anchors on a fair value of $29.67 per share, which sits above the recent $23.37 close and frames the LG Ad Solutions renewal as part of a broader CTV and DV+ earnings story rather than a one off headline.

The main thing that has to go right is that Magnite continues to convert its position in CTV, commerce media partnerships, OEM and home-screen wins, and AI and agent-based infrastructure into durable share gains across both CTV and DV+.

The numbers imply a share price that treats Magnite’s raised 2026 guidance for contribution ex-TAC growth, adjusted EBITDA margins, and free cash flow growth, alongside its low net leverage and ongoing buybacks, as not fully reflecting the company’s long-term earnings power.

See why 13 investors see Magnite as 21% undervalued.

Result: Fair Value of $29.67 (UNDERVALUED)

Still, Magnite’s reliance on a concentrated group of large CTV streamers, along with the pressure in web display from shifting referral traffic, could quickly challenge that 21% undervalued story.
