The computer chip maker Intel on Friday blamed an internal error for a data leak that prompted it to release a quarterly earnings report early.
It said its corporate network was not compromised.
The company's chief financial officer, George Davis, had earlier told The Financial Times that Intel published its earnings ahead of the stock market's close on Thursday because it believed a hacker stole financially sensitive information from the site.
The company's quarterly results were originally scheduled to be published hours later after the close of trading on Wall Street Thursday.
"An infographic was hacked off of our PR newsroom site," the newspaper quoted Davis as saying. It quoted an unnamed company spokesperson as saying Intel was notified that the graphic was circulating outside the company.
