IBM says federal regulators are looking into how the company reports sales for its cloud-computing business.
The technology company disclosed in a regulatory filing Wednesday that it learned in May that the Securities and Exchange Commission was conducting an investigation.
IBM started its cloud business in 2007 and has spent billions since then acquiring related businesses.
It is one of a number of technology companies shifting its focus to cloud computing, which allows customers to use software and other services online, rather than on their own computers.
IBM provided no further details on the investigation. A representative for the company was not immediately available to comment.
The SEC declined to comment.
