Yahoo Inc. is taking a $350-million hit on its previously announced $4.8-billion sale to Verizon Communications Inc. in a concession for security lapses that exposed personal information stored in more than 1 billion Yahoo user accounts.
The revised agreement announced Tuesday eases investor worries that Verizon would demand a discount of at least $1 billion or cancel the deal entirely.
The hacking bombshells, disclosed after the two companies agreed on a sale, represent the two biggest security breaches in Internet history.
The security breaches raised concerns that people might decrease their usage of Yahoo email and other digital services that Verizon is buying. A smaller audience makes Yahoo's services less valuable because it reduces the opportunities to show ads — the main reason that Verizon struck the deal seven months ago.
Yahoo — based in Sunnyvale, Calif. — has maintained that its users have remained loyal, despite any mistrust that might have been caused by its lax security and the lengthy delay in discovering and disclosing the hacks. The separate attacks occurred in 2013 and 2014; Yahoo disclosed them this past September and December.
The lower sales price, now pegged at $4.48 billion, will cost Yahoo shareholders roughly 37 cents a share. They may also be responsible for substantial legal costs.
What's left of Yahoo after the deal closes — an entity that will be called Altaba Inc. and have stakes in Chinese e-commerce giant Alibaba Group and Yahoo Japan — will be responsible for liabilities stemming from shareholder lawsuits and from the Securities and Exchange Commission investigation of Yahoo. Verizon and Altaba will split costs from all other hack-related lawsuits and government investigations.
This agreement "provides protections for both sides" and should help the deal close by the end of June, Marni Walden, Verizon's head of product innovation and new businesses, said in a statement. Yahoo shareholders have yet to approve it.
Avoiding an even larger reduction in the deal value represents a small victory for Yahoo Chief Executive Marissa Mayer, who had already been under fire on Wall Street for her inability to turn around the company and then for the humiliating security lapses that came under her watch.
"Yahoo had to get this deal done. There is no better fit for them than Verizon," said Doug Melsheimer, managing director for Bulger Partners, an investment banking firm specializing in technology.
Mayer, 41, is widely expected to step down after Verizon takes over, although she hasn't spelled out her plans definitively. If she departs, Mayer will leave with a severance package that was valued at $44 million last summer. The package is probably worth even more now because it primarily consists of Yahoo stock, which has risen nearly 20% since last summer.
On Tuesday, Yahoo shares rose 40 cents to close at $45.50, and Verizon's stock rose 24 cents to finish at $49.43.
Verizon's willingness to accept some of the lingering risks from Yahoo's security breaches underscores the wireless carrier's desire to become a bigger player in the digital advertising market. Google and Facebook currently dominate, but Verizon believes there's room to grow.
Because most people already have smartphones, wireless carriers such as Verizon have turned to price cuts and promotions to lure customers from each other. Under pressure, Verizon even restored unlimited data plans this month, robbing it of revenue from monster-size data plans.
Instead, Verizon is trying to make money off the hours people spend gazing at their phones. It bought AOL for $4.4 billion in 2015 for its advertising technology. Verizon now wants to bolster that with Yahoo's technology, as well as its more than 1 billion users and popular websites devoted to sports, finance, entertainment and news.
"It has made sense for AOL and Yahoo to be combined for a very long time," Melsheimer said. "It has just been a very long route getting there."
