Celestica CEO Rob Mionis explained how his company designs and manufactures infrastructure that enables artificial intelligence in a Tuesday interview with CNBC’s Jim Cramer.

“If AI is a speeding freight train, we’re laying the tracks ahead of the freight train,” Mionis said.

He pushed back against the notion that the AI boom is a bubble, saying that the technology has gone from a “nice to have” to a “must have.”

Celestica reported earnings Monday after close, managing to beat estimates and raise its full-year outlook. The stock hit a 52-week high during Tuesday’s session and closed up more than 8%. Celestica has had a huge run over the past several months, and shares are currently up 253.68% year-to-date.

Mionis described some of Celestica’s business strategies, including how the Canadian outfit chose to move away from commodity markets and into design and manufacturing. He told Cramer that choice “has paid off in spades” for his company.

Celestica’s focus on design and manufacturing enables the company to “consistently execute at scale,” he added.

He detailed Celestica’s data center work, saying the company makes high-speed networking and storage system for hyperscalers, digital native companies and other enterprise names.

Mionis praised the company’s partnership with semiconductor maker Broadcom, saying Celestica uses Broadcom’s silicon in a lot of its designs.

“What it means for us is when they launch a new piece of silicon — so the Tomahawk 6 is their 1.6 terabyte silicon — when they launch that into the marketplace, they’ll work with us to develop products, and those products end up in the major hyperscalers.”
