Hinge Health, Inc.

Classified Board of Directors

In accordance with our Certificate of Incorporation, our Board of Directors is divided into three classes with staggered three-year terms. At each annual general meeting of stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following election. Our directors are divided among the three classes as follows:

•The Class I directors are Teddie Wardi and Tyler Sloat, and their terms will expire at the annual meeting of stockholders to be held in 2026;

•The Class II directors are Gabriel Mecklenburg and Kristina Leslie, and their terms will expire at the annual meeting of stockholders to be held in 2027; and

•The Class III directors are Daniel Perez and Elliott Robinson, and their terms will expire at the annual meeting of stockholders to be held in 2028.

We expect that any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors. The division of our Board of Directors into three classes with staggered three-year terms may delay or prevent a change of our management or a change in control.
