Fundamentals
Valuation and ratings
Magnite, Inc. trades at $25.26, which is 30% above the $17.59 our fair value estimate puts on the business. On that measure it screens as expensive, which is not the same as saying it will fall.
Our moat model scores it 70 out of 100, which is a wide moat. A moat is a structural reason competitors cannot take the profits away, and it matters more to a long holding period than any single quarter's numbers do.
It changes hands at 18.1 times earnings. Be careful reading that in isolation: for a cyclical business a low P/E arrives at the top of the cycle, when profits are peaking and about to fall, which is exactly when the shares look cheapest and are not.

Estimates are the published analyst consensus and move often. An earnings date is scheduled, not certain, and a share tends to reprice most violently on the day itself.

Common questions
Is Magnite, Inc. (MGNI) undervalued?
Against our fair value estimate of $17.59, MGNI at $25.26 is 30% above fair value. That is one model's answer, not a recommendation. It is built from normalized earning power with growth capped deliberately low, which understates companies whose value is mostly future growth.
Which funds own MGNI?
9 of the institutions we track reported a position in MGNI in their most recent SEC 13F filing. A 13F is filed up to 45 days after quarter end, so it tells you what a fund held then, not what it holds now.
What is MGNI's P/E ratio?
MGNI trades at 18.1 times earnings. A low P/E is not automatically cheap: on a cyclical company it is usually a warning that earnings are at a peak.
