Glucose monitoring systems provider Dexcom, Inc. (DXCM) was one of the biggest gainers on Thursday, with a climb of $29.25, or 30.65% to trade at $124.69.

The gain came after the firm revealed better-than-expected quarterly financial results for the three months ended June 30, 2018.

Net profit jumped 941% to $30.2 million, thanks to significant adoption of continuous glucose monitors (CGMs) that are used by persons with diabetes. Meanwhile, net sales grew 42% to $242.5 million from the same quarter a year ago.

Diabetes patients are increasingly using CGMs to regulate their blood sugar levels. CGMs rely on tiny sensors placed under the skin that regularly harvest and convey data to a separate receiver, which calculates, tracks, and reports blood glucose levels.

DexCom shares have soared 66% since the beginning of the year. The stock has climbed 43% in the last twelve months.

DexCom CEO Comments

Commenting on the results, DexCom President and Chief Executive Officer Kevin Sayer said, “Q2 was a fantastic quarter for DexCom and demonstrates that CGM adoption is increasing significantly.
