Acxiom had rejected ValueAct's first offer, saying the price was too low. In a letter to Acxiom's board Friday, ValueAct said that Acxiom's most recent financial results, released on Oct. 19, confirm that the company is in need of new leadership. "The second-quarter results reported on Oct. 19 further confirm our belief that assets are being poorly deployed, opportunities missed, and that shareholder value is being eroded by current management," ValueAct said in a regulatory filing. "It is clear to us that there is an urgent need for a fundamental change in the company's strategic direction. It is also clear that the only way to bring about that change is by replacing Acxiom's leadership." Acxiom shares recently gained $1.09 to $21.13.
