mrspoonsi writes: On Monday morning, Eric Jackson, manager of hedge fund SpringOwl, sent a brutal 99-page presentation to Yahoo's board, outlining his case for why the company should drop Marissa Mayer as CEO and find new management. Jackson points out that Yahoo has burned through $3 billion on M&A in the past three years since Mayer took the reins, which contributes to $10 billion in what Jackson calls Yahoo's misallocated capital. The value of all of those startups Yahoo has acquired, Jackson says, is worth nothing at Yahoo's current stock price. Jackson also points out that Yahoo has a history of buying up startups run by former Google APM members. While at Google, Mayer started the company's elite associate product-manager program. Of the 49 acquisitions Yahoo has made under Mayer's leadership, six were startups founded by ex-Googlers. The total cost of these six acquisitions is $319 million, according to Jackson's slide deck. Yahoo bought Polyvore in July for $230 million. Polyvore, a social commerce site that lets users make artistic collages of clothes and accessories...But Jackson does not mince words when it comes to Yahoo's decision to spend shareholder money acquiring Polyvore and companies like it. "It's not acceptable to pay $230M for zombie companies run by former APM members," he says, pointing out that Polyvore had raised $22 million in VC funding, was 8 years old, and had gone through multiple pivots. For all intents and purposes, it looked like a goner until Yahoo bought it.
