Whitney Tilson on Primo Brands

In recent weeks, a daily newsletter from former hedge fund manager Whitney Tilson has been warning investors of signs of the AI bubble popping. Tilson took a break from the bearish sentiment to share his thoughts on some of the new stock picks from Einhorn.

"When I took a quick glance at the stock, I noted that it has had many ups and downs since its 1992 IPO," Tilson wrote.

The former hedge fund manager notes that the stock ran up to $35 last year before pulling back to $22 recently.

Tilson notes that the company is the result of a merger between BlueTriton and Primo Water in 2024, leaving limited financial results. Since 2021, the company’s revenues have doubled and operating income went from nearly nothing to more than $700 million annually.

Dividends and share buybacks are also highlighted by Tilson in the write-up.

"Overall, this is a solid financial picture. It’s a good — though not great — business, and all of the key metrics are trending in the right direction."

Tilson says the stock trades at around 16.5x this year’s expected earnings per share and 14.5x next year’s expected earnings per share, making the stock modestly cheap.

The investor shared a bullish case on Primo Brands from a user who pointed out bottled water is an attractive investment area. The user also shared that Primo Brands has strong retail market share for bottled water and the direct delivery market.

Tilson highlights another user sharing the bear case of Primo having "worsening unit economics" with slower growth coming. Problems include higher diesel prices and more tap water solutions available to consumers now than before.

Ultimately with the bull and bear case, Tilson looks to remain on the sidelines.

"Forced to go long or short this stock, I’d go long — but not with much conviction. In light of the number of current and potential headwinds, the stock isn’t cheap enough to be attractive," Tilson said.

Tilson said Primo Brands will remain on his watchlist given Einhorn’s investment.
