Dear Stockholder:

I am pleased to invite you to attend the Annual Meeting of Stockholders of Groupon, Inc. (the “Annual Meeting”), which will be held at Winston & Strawn LLP, 300 North LaSalle Drive, Suite 4600, Chicago, Illinois 60654, on June 11, 2026 at 9:00 a.m. Central Time. The doors will open at 8:30 a.m. Central Time.

The attached Notice of Annual Meeting of Stockholders and proxy statement (the “Proxy Statement”) contain details of the business to be conducted at the Annual Meeting.

Whether or not you attend the Annual Meeting, it is important that your shares be represented and voted at the meeting. Therefore, I urge you to promptly vote and submit your proxy via the Internet, by phone, or by signing, dating and returning the enclosed proxy card in the enclosed envelope. If you decide to attend the Annual Meeting, you will be able to vote in person, even if you have previously submitted your proxy.

We urge you to read the accompanying Proxy Statement carefully and to vote “FOR” the director nominees proposed by the Board of Directors, “FOR” the ratification of Deloitte & Touche LLP as our independent registered public accounting firm for fiscal year 2026, “FOR” the non-binding, advisory approval of our named executive officer compensation, and "FOR" the amendment to our Restated Certificate of Incorporation to provide for officer exculpation as permitted by Section 102(b)(7) of the Delaware General Corporation Law. On behalf of the Board of Directors, I would like to express our appreciation for your interest in Groupon.

Sincerely,

Theodore Leonsis

Chairman of the Board of Directors

Proxy Voting

IMPORTANT: Please vote your shares at your earliest convenience. This will ensure the presence of a quorum at the Annual Meeting.

Important Notice Regarding the Availability of Proxy Materials for the Annual Meeting to Be Held on June 11, 2026. We are furnishing proxy materials to our stockholders primarily via the Internet, instead of mailing printed copies of those materials to each stockholder. By doing so, we save costs and reduce the environmental impact of our Annual Meeting. We will mail a Notice of Internet Availability of Proxy Materials (the “Notice”) to certain of our stockholders. The Notice contains instructions about how to access our proxy materials and vote online or vote by telephone. If you would like to receive a paper copy of our proxy materials, please follow the instructions included in the Notice.
