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 approximately 25 stockholders of record as of February 5, 2026. 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

All unregistered sales of equity securities have been previously disclosed in a Form 10-Q or a current report on Form 8-K for the fiscal year ended December 31, 2025.

Purchases of Equity Securities by the Issuer and Affiliated Purchasers

In April 2025, our Board of Directors authorized and approved a share repurchase program of up to $750.0 million of our outstanding common stock, with a repurchase period ending no later than June 30, 2026 (the “2025 Share Repurchase Program”).

See Note 8 “Employee Benefit Plans and Stockholders’ Equity” to the consolidated financial statements in Part II, Item 8 of this Annual Report on Form 10-K for additional information about our share repurchases during the year ended December 31, 2025.
