Microsoft’s stock hit an all-time high — beating its previous record set during the dot-com bubble of 1999 — after the tech giant posted blowout earnings Thursday.

Propelled by strong demand for its Surface tablets and torrid growth at its Azure cloud-computing unit, shares of the company founded by Bill Gates surged 6 percent to $60.70 in after-hours trading.

That record high — eclipsing the previous high watermark of $59.97 set on Dec. 30, 1999 — gave Microsoft a market capitalization of $472.4 billion.

The rally likewise bolstered Microsoft’s position as the world’s third-most valuable company behind Apple and Alphabet, and extended its lead over fourth-ranked Amazon.

Indeed, Microsoft’s Azure division — a cloud-computing arch-rival to Amazon Web Services that hosts Web sites and mobile apps, stores data and performs analytics services — more than doubled its revenue in the most recent quarter.

Meanwhile, revenue from the Surface line of tablets and notebooks jumped 38 percent to $926 million — outpacing the slowing growth of Apple’s iPad line, which in Apple’s most recently reported quarter rose 11 percent to $4. 9 billion.

Credit for the turnaround is going to Chief Executive Satya Nadella, who took the reins from Steve Ballmer in February 2014.
