Humana Wednesday reported $545 million in second quarter profits as the health insurer’s medical cost trends fell in line with expectations.

Humana raised its annual profit forecast after beating quarterly estimates on Wednesday, as the U.S. health insurer succeeded in keeping its medical costs in check, in contrast to several of its rivals who recently slashed their expectations.

The Kentucky-based company’s results are a bright spot in what’s otherwise been a gloomy quarter for health insurers. Humana says it has a handle on snowballing medical costs after taking a conservative stance heading into the year.
