The New York Post reported Wednesday that buyout negotiations for California Pizza Kitchen ended without a deal, sending the company’s stock downward.

The Post cited a source who said American Securities Capital, a New York private equity fund, had failed to reach an agreement with the restaurant chain, and that it was “unlikely” talks would resume given the disagreements.

Los Angeles-based California Pizza Kitchen in April announced its intention to sell itself and hired consultancy Moelis & Co. to review its strategic options. That announcement occasioned a spike in the company’s stock price which gradually dissipated until last week, when the Post reported advanced talks with American Securities Capital.

It is not clear if California Pizza Kitchen is in negotiations with any other potential buyers.

At midday on the Nasdaq Stock Exchange, shares of California Pizza Kitchen had lost $1.70 or 10 percent of their value to trade at $15.92.
