Yahoo CEO Said Microsoft's $44.6 Billion Offer "Substantially Undervalues" the Company. Eight Years Later, It Sold for $4.8 Billion.

When Microsoft came knocking with $44.6 billion in cash and stock — a 62% premium over Yahoo's market value — Jerry Yang looked at the offer and essentially said: "That's insulting." He demanded at least $37 per share, up from Microsoft's $31. Steve Ballmer raised it to $33 ($47.5 billion total). Yang still said no. Microsoft walked away in May 2008. Yang stepped down as CEO by November.

The aftermath was painful to watch. Yahoo's stock cratered during the financial crisis. The company stumbled through multiple CEOs, failed strategies, and increasingly desperate pivots. The Alibaba stake (which Yang gets credit for) was the only thing keeping shareholders from full revolt.

In 2016, Verizon bought Yahoo's core internet business for $4.8 billion — roughly 10% of what Microsoft offered. The deal was so sad that even Verizon eventually wrote down $4.6 billion of goodwill.

Yang's defense? He believed Yahoo could transform into a media and advertising powerhouse to rival Google. Instead, he created one of the most expensive "no" in corporate history. That $40 billion difference between Microsoft's offer and Verizon's price tag? That's not a rounding error. That's a cautionary tale about knowing when to take the money and run.
