Ultra Clean Holdings

Ultra Clean does not have to pick which chip company wins, because it sells into the equipment that nearly all of them use. The company brings in more than 2 billion dollars a year and management has set a target of reaching 4 billion by 2030. Every new chip factory built for AI needs the exact parts Ultra Clean makes.

This business is built to swing hard when spending recovers. Sales dipped about 2 percent over the past year, which is a mild dent for an industry this cyclical, and much of the cost base stays flat whether orders rise or fall. That means a return to growth can flow straight to the bottom line without needing a huge jump in revenue.

Right now the company is losing money. Net margins are running around negative 9 percent, so for every 100 dollars of sales, roughly 9 dollars is going out the door instead of into profit. Until that flips positive, this is a turnaround story rather than a steady earner.

Roughly 60 percent of Ultra Clean's sales come from just two big customers. If either one trims orders, pushes for lower prices, or decides to build parts in house, the hit lands immediately. The stock also moves about twice as much as the overall market, so drops can be sharp and fast.
