Roubaix’s Magnite Exodus: A Tale of Exit and Echoes

Roubaix Capital, LLC, that shrewd and sly investor, recently bid farewell to its stake in Magnite, offloading 260,735 shares worth a tidy $6.29 million. A curious exit, one might say, as if the fund had stumbled upon a cursed treasure and decided to flee before the curse could strike.

What happened

The enigmatic Roubaix Capital, LLC, in a move as sudden as a thunderclap, liquidated its entire holding in Magnite (MGNI 3.92%), casting 260,735 shares into the void during Q3 2025, per a cryptic scroll filed with the Securities and Exchange Commission on November 12, 2025. The sum? A modest $6,288,928, though the true value lies in the silence that followed. By quarter’s end, no shares of Magnite lingered in the fund’s vaults, as though the company had been swallowed by a black hole of doubt.

What else to know

Roubaix’s departure was not merely a sale but a ritual of erasure, reducing its stake from 3.0% of AUM to a hollow zero. The fund’s new allies, now its top holdings, include:

TATT: $11 million (5.1% of AUM)
PKE: $9.2 million (4.3% of AUM)
GENI: $8.6 million (4.0% of AUM)
NPKI: $8.4 million (3.9% of AUM)
LASR: $7.2 million (3.4% of AUM)

As of November 13, 2025, Magnite’s shares languished at $14.21, a wistful echo of their former glory. The year-to-date decline of 10.7% paints a picture of a ship adrift, outpacing the S&P 500 by a grim 27.2 percentage points.

Company Snapshot

Magnite, Inc. operates a peculiar realm where publishers barter digital ad space, a realm governed by algorithms as capricious as a child’s mood.
It is a technicolor bazaar, connecting sellers of digital media with buyers who chase clicks like a hound after a hare.
Its clients? Publishers, CTV channel operators, advertisers, and agencies-each a player in a game of chess where the pieces are pixels and profit margins are the king.

Foolish take

Roubaix’s grand exit from Magnite’s realm suggests a tale of woe, for the digital ad world has been a tempest of late. Magnite, once a titan of programmatic advertising, now grapples with the shadow of shrinking CTV ad budgets and the gnawing claws of privacy laws. Yet, even as its shares wilt like a flower in a drought, Magnite remains a colossus in the digital advertising ecosystem, its infrastructure as robust as a fortress.

Investors, ever the cautious voyagers, weigh the near-term storms against the distant promise of CTV’s dawn. Roubaix’s departure may signal a pivot toward greener pastures, but history whispers that when the winds shift, Magnite’s towers may yet rise again, their foundations unshaken.
