Alphabet  (GOOGL) - Get Report CEO Larry Page is stepping down, the company said on Tuesday after the market close.

Going forward, Sundar will be the CEO of both Google and Alphabet. He will be the executive responsible and accountable for leading Google, and managing Alphabet's investment in our portfolio of Other Bets."

Pichai joined Google in 2004 and helped develop the Chrome web browser.

Page and Brin will remain on Alphabet's board of directors.

Shares of Alphabet were up 0.56% at $1,302 in premarket trading on Wednesday.
