Arm Chief Executive Officer Rene Haas, gearing up for the biggest initial public offering of the year, is pitching investors on a pivot.

His message to potential shareholders is that Arm is poised to become a bigger and more profitable business — not just because of the industrywide boom in cloud computing and artificial intelligence, but also due to a major change in how it operates.

"We made a significant shift in our strategy,” Haas said in a video presentation for prospective investors seen by Bloomberg.
