Item 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Market Information for Common Stock

Our common stock is traded on the Nasdaq Global Select Market under the symbol “DXCM.”

Stockholders

We had fewer than 40 stockholders of record as of December 31, 2022. The number of beneficial owners of our common stock at that date was substantially greater than the number of record holders because a large portion of our common stock is held of record through brokerage firms in “street name.”

Dividend Policy

We have never declared or paid any cash dividends on our capital stock. We currently intend to retain any future earnings to finance the operation and expansion of our business, and we do not expect to declare or pay any dividends in the foreseeable future.

Recent Sales of Unregistered Securities

There were no unregistered sales of equity securities which have not been previously disclosed in a quarterly report on Form 10-Q or a current report on Form 8-K during the fiscal year ended December 31, 2022.

Purchases of Equity Securities by the Issuer and Affiliated Purchasers

On July 28, 2022, we announced that a duly authorized committee of our Board of Directors authorized and approved a share repurchase program of up to $700 million of our outstanding common stock, with a repurchase period ending no later than June 30, 2023. As of December 31, 2022, approximately $142.3 million remained available for repurchase pursuant to our share repurchase program.

The following table provides information about purchases by the Company of its shares of common stock during the three months ended December 31, 2022:
