**ITEM 5.02.&nbsp;&nbsp;&nbsp;&nbsp;DEPARTURE OF DIRECTORS OR CERTAIN OFFICERS; ELECTION OF DIRECTORS; APPOINTMENT OF CERTAIN OFFICERS; COMPENSATORY ARRANGEMENTS OF CERTAIN OFFICERS.**

On February 26, 2026, the Board of Directors (the "Board") of DexCom, Inc. ("Dexcom" or the "Company"), pursuant to the Amended and Restated Bylaws of the Company, increased the size of the Board to twelve directors and appointed Albert F. ("Rick") Osterloh, IV as a director effective immediately. Mr. Osterloh will hold office for a term expiring at the 2026 annual meeting of Dexcom's stockholders (the "2026 Annual Meeting"). The Board also appointed Mr. Osterloh to serve as a member of the Compensation Committee and the Technology Committee of the Board, effective immediately.

There is no arrangement or understanding between Mr. Osterloh and any other persons pursuant to which Mr. Osterloh was selected as a director. Mr. Osterloh is not a party to and does not have any direct or indirect material interest in any transaction with Dexcom required to be disclosed under Item 404(a) of Regulation S-K. The Board determined that Mr. Osterloh qualifies as an independent director pursuant to the Securities Act of 1933, as amended, and the listing standards of the Nasdaq Stock Market, in each case as currently in effect. Mr. Osterloh also entered into Dexcom's standard form of indemnity agreement for its directors and executive officers, which was filed as Exhibit 10.43 to Dexcom's Annual Report on Form 10-K for the fiscal year ended December 31, 2020, as filed with the Securities and Exchange Commission on February 11, 2021.

In accordance with Dexcom's non-employee director compensation program, upon his appointment Mr. Osterloh was granted an initial appointment equity grant of restricted stock units ("RSUs") with a fair value of $500,000, vesting annually over the three years following the date of grant, subject to Mr. Osterloh's continued service. Mr. Osterloh will also be eligible to receive the annual equity grant to non-employee directors on or around the 2026 Annual Meeting in the form of a grant of RSUs with a fair value of $101,027 for his service on the Board and committees (which amount reflects a pro-rata reduction in the base annual award amount for Board service of $325,000, calculated according to the number of days Mr. Osterloh will actually serve as a director between now and the 2026 Annual Meeting). The annual award vests on the earlier of the date of the first annual stockholder meeting thereafter or one year from the date of grant, subject to continued service. Vesting of outstanding equity awards held by non-employee directors is accelerated in full upon a change in control of Dexcom.

**ITEM 7.01.&nbsp;&nbsp;&nbsp;&nbsp;REGULATION FD DISCLOSURE.**

On February 26, 2026, Dexcom announced the appointment of Mr. Osterloh to the Board in a press release furnished as Exhibit 99.1 to this report and is incorporated herein by this reference.
