Verizon Communications Inc. plans to make a first-round bid for Yahoo Inc.'s Web business next week, and is willing to acquire the company's Yahoo Japan Corp. stake to help sweeten the offer, according to people familiar with the matter.

Google, the main division of Alphabet Inc., is also considering bidding for Yahoo's core business, a separate person said.

Potential suitors AT&T Inc. and Comcast have decided against bidding, some of the people said, asking not to be identified as the discussions are not public. Microsoft Corp., which failed with a hostile bid for Yahoo in 2008, will not bid this time, another person said.
