Magnite (MGNI): Assessing Valuation as LocalLinear TV Private Marketplace Launch Unifies TV and Digital Programmatic Access

Simply Wall St

Magnite (MGNI) and ITN are rolling out the industry’s first LocalLinear TV Private Marketplace. This new offering puts programmatic access to local linear TV and digital video together on a single platform for the first time.

Magnite’s launch of the LocalLinear TV Private Marketplace arrives just as momentum in its stock remains robust over the longer term. The share price has eased back around 12% over the last month; however, strong one-year total shareholder returns of 45% and a tremendous 185% gain over three years showcase the company’s staying power and growing appeal for long-term holders, even amid some short-term volatility.

If Magnite’s expansion into local TV automation has you thinking bigger, this could be the perfect moment to broaden your perspective and discover fast growing stocks with high insider ownership

With strong multi-year returns and a share price currently at a substantial discount to analyst targets, the question for investors is clear: is Magnite undervalued, or is the market already anticipating its next wave of growth?

Most Popular Narrative: 37.1% Undervalued

Compared to the last close price of $17.74, the most widely followed narrative pegs Magnite’s fair value much higher. This creates a sharp value gap that has caught the market’s attention. Behind this figure is a bold growth story and a set of projections that could signal major upside if realized.

"Anticipated regulatory changes resulting from the DOJ antitrust case against Google could lead to meaningful market share shifts in DV+, potentially creating $50M in incremental annualized contribution ex-TAC for every 1% share gain without a material increase in operating costs. This could materially improve earnings leverage."

The narrative hinges on aggressive earnings trajectories, a dramatic shift in margins, and a future valuation multiple that could make or break long-term returns.

Result: Fair Value of $28.19 (UNDERVALUED)

However, high exposure to major streaming partners and any delay in regulatory outcomes could quickly challenge Magnite’s growth thesis and potential for valuation upside.

Another View: What Do the Ratios Say?

Taking a look through the lens of price-to-earnings comparisons, Magnite currently trades at 59 times earnings. That's significantly higher than the US Media industry average of 18.3x, yet lower than the peer average of 65.5x. Interestingly, the fair ratio our models suggest is 27.5x, which is well below today's level. This notable gap signals both opportunity and risk depending on how quickly the business can grow into its valuation or whether the market eventually re-prices these expectations. Could this elevated multiple be justified, or is there more caution warranted here?
