Former Microsoft CEO Steve Ballmer bought a 4 percent stake in Twitter over recent months, he tweeted on Friday.

After urging users on his verified Twitter account follow him at a new one, @Steven_Ballmer, Ballmer praised new CEO Jack Dorsey and changes Twitter has made.

“Good job innovation, CEO, leaner, more focused,” he tweeted. He concluded by boasting, “Glad I bought 4% past few months.”

His 4 percent ownership, which he confirmed to Bloomberg, makes him one of the company’s largest shareholders, trailing only Saudi Prince Alwaleed Bin Talal and Twitter co-founder Evan Williams.

Ballmer also praised Bin Talal, saying he liked his move to bump his ownership stake up to 5 percent last week.

Shares of Twitter were up nearly 5 percent at the end of trading on Friday, to $31.15 per share. Ballmer’s ownership stake isn’t on file with the Securities and Exchanges Commission since it’s not required for ownership under 5 percent.

Ballmer’s ownership amounts to $810 million and is more than that of Dorsey, who owns a 3 percent stake in the company.
