NOTICE OF ANNUAL MEETING OF SHAREHOLDERS

To our shareholders:

Notice is hereby given that the 2026 annual meeting of shareholders of Shenandoah Telecommunications Company will be held in the auditorium of the Company's offices at 500 Shentel Way, Edinburg, Virginia 22824 on Tuesday, April 21, 2026, at 11:00 a.m., Eastern Time, for the following purposes:

1. to consider and vote upon a proposal to elect the following directors of the Company to the Board of Directors of the Company (the “Board”): Matthew S. DeNichilo, Kenneth L. Quaglio and Michael A. Rhymes as Class 1 directors for a term expiring at the annual meeting of shareholders in the year 2029 (collectively, the “Nominees”);

2. to ratify the Audit Committee’s selection of RSM US LLP as the Company’s independent registered public accounting firm for 2026;

3. to consider and approve, in a non-binding vote, the Company’s named executive officer compensation; and

4. to consider and act upon any other business as may properly come before the meeting or any adjournment or postponement thereof.

Only shareholders of record at the close of business on February 23, 2026 will be entitled to notice of, and to vote at, the annual meeting or any adjournment or postponement thereof. All shareholders are cordially invited to attend this meeting. A light lunch will be provided.

Shareholders who wish to submit questions may do so in writing in advance of the Annual Meeting on our pre-meeting forum at www.proxyvote.com using their control number.

We have elected to furnish certain proxy materials to our shareholders electronically, so that we can provide our shareholders with the information they need while also reducing our costs of printing and delivery and the environmental impact of our annual meeting.

Your vote is very important to us. Whether or not you plan to attend the meeting in-person, your shares should be represented and voted. Please promptly vote your proxy. You may vote online at www.proxyvote.com where you will need to enter the control number provided in the proxy materials, and then follow the instructions provided. Submitting your proxy online, by telephone or by mail before the annual meeting will not preclude you from voting in-person during the annual meeting if you should decide to attend.

By Order of the Board of Directors,

Angela M. Olsen

Secretary

Dated: March 9, 2026
