#### PROPOSAL 1

### ELECTION OF DIRECTORS
Tenable’s Board of Directors is divided into three classes and each class has a three-year term. Vacancies on the Board may be filled only by persons elected by a majority of the remaining directors. A director elected by the Board to fill a vacancy in a class, including vacancies created by an increase in the number of directors, shall serve for the remainder of the full term of that class and until the director’s successor is duly elected and qualified.

The Board of Directors currently consists of eight members. There are two directors in the class whose term of office expires in 2025. Mses.
