Yahoo shareholders didn't exactly give a ringing endorsement to Marissa Mayer this week

Yahoo CEO Marissa Mayer's failure to turn around the company has frustrated a lot of investors in recent years.

That loss of support was perhaps most apparent in the number of "against" votes she received for board re-election at the company's annual shareholder meeting held on Thursday.

According to regulatory filing on Friday, Mayer has received 104.9 million votes that opposed her return to the company's board of directors. That's over 15% of the total votes.

Ironically, Jeffrey Smith, the activist investor who joined Yahoo's board this year after pressuring the company to sell, drew the second most "against" votes, according to the filing. Nearly 93 million votes were against his position on Yahoo's board, which shows there may be tension between Smith's camp and Mayer supporters.
