Yahoo (NASDAQ:YHOO) will be one to watch this morning with the release of its earnings and the integration of its new CEO. Yesterday, the internet company posted second quarter earnings per share of $0.18, that’s below analyst estimates of $0.20 a share. Revenue for the quarter fell 1% to $1.08 billion, just below analyst estimates of $1.10 billion. Income fell 4% from the prior year as well to $227 million.Although not great earnings, investors are now looking to see what the new CEO Marissa Mayer will do to reinvigorate the company. Yahoo struggled through two different CEO’s last quarter, Scott Thompson and then interim CEO Ross Levinsohn so both the Yahoo’s board and investors are looking for a change. The biggest challenge Mayer will face: finding a way to compete with rivals such as Google and Facebook.
