May 9 (Reuters) - Engine Capital said on Friday it would

end its activist campaign at Lyft ( LYFT ) and withdraw its

board nominees after the ride-hailing platform boosted its stock

buyback program.

The company increased its stock buyback program to $750

million from $500 million, and said it intends to use $500

million of the authorization within the next 12 months.

Last week, Engine Capital had urged Lyft ( LYFT ) to undertake a $750

million accelerated repurchase, and to consider strategic

alternatives, including a sale.

Lyft ( LYFT ) did not immediately respond to a request for comment.
