120,191,047 shares outstanding and entitled to vote. Thus, the holders of 60,095,524 shares must be present online at the meeting or represented by proxy at the meeting to have a quorum.

Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the chairperson of the meeting or the holders of a majority of shares present online at the meeting or represented by proxy may adjourn the meeting to another date.

Will a list of record stockholders as of the Record Date be available?

Upon request, a list of our record stockholders as of the close of business on the Record Date will be made available to stockholders. In addition, for the ten days ending the day prior to the Annual Meeting, the list will be available upon request for examination by any stockholder of record for a legally valid purpose. To access the list of record stockholders beginning May 4, 2025 and until the Annual Meeting, stockholders should email David Bartholomew, Deputy General Counsel, at dbartholomew@tenable.com.

#### How do I ask a question at the Annual Meeting?
Only stockholders of record as of March 17, 2025 may submit questions or comments in advance of the virtual stockholders meeting, not during. If you would like to submit a question or comment, you may do so prior to 5:00 p.m. Eastern Time on May 13, 2025 by following the instructions in your registration documents on https://www.proxydocs.com/TENB.

To help ensure that we have a productive and efficient meeting, and in fairness to all stockholders in attendance, you will also find posted our rules of conduct for the Annual Meeting when you log in prior to the start of the Annual Meeting. Our management may group pre-submitted questions by topic with a representative question read aloud and answered. In addition, questions may be ruled out of order if they are, among other things, irrelevant to our business, related to pending or threatened litigation, disorderly, repetitious of statements already made, or in furtherance of the speaker's own personal, political or business interests
