CVS Caremark Corp. said Tuesday that its third-quarter earnings climbed 16 percent. The drugstore operator and pharmacy benefits manager posted revenue increases in both businesses, benefiting from new customers won from rivals, and raised its full-year earnings outlook.

The Woonsocket, R.I., company said it earned $1.01 billion, or 79 cents per share, in the three months ended Sept. 30.

That compares with earnings of $868 million, or 65 cents per share, in last year’s quarter. Adjusted earnings were 85 cents per share, 2 cents better than analysts expected.

That excluded $121 million for the gradual writedown of acquisition-related assets.

Revenue jumped 13 percent to $30.2 billion, above the $30.09 billion analysts expected.

CVS shares closed up 25 cents at $46.88.
