UnitedHealth Group Inc. (NYSE:UNH) spent much of its second-quarter earnings call talking about recovering margins, stronger guidance and operational improvements. But there was another message hidden in plain sight.

The company couldn’t stop saying one word: “restless.”

At first glance, it sounds like little more than executive jargon. Look closer, however, and the repeated use of the word reveals how CEO Stephen Hemsley wants Wall Street to think about UnitedHealth’s next phase—not as a company that’s finished fixing its problems, but one that’s committing itself to constant reinvention.
