Highlights Radoff-Sudbury Group Nominees Will Bring Differentiated Experience and Fresh Perspectives to the Board

Notes Leading Independent Proxy Advisory Firms ISS and Glass Lewis Concluded that Boardroom Change is Warranted

Urges Stockholders to Vote for Dayton Judd, Michael Lohner and Bradley L. Radoff on the BLUE Proxy Card Ahead of the November 6^th Annual Meeting

Bradley L. Radoff and Sudbury Capital Fund, LP (together with their affiliates, the “Radoff-Sudbury Group,” “we” or our “Group”), represent the largest stockholder of LifeVantage Corporation (Nasdaq: LFVN) (“LifeVantage” or the “Company”), collectively owning approximately 12.8% of the Company’s outstanding stock. Today, the Group issued the following letter to LifeVantage stockholders ahead of the Company’s upcoming Annual Meeting of Stockholders (the “Annual Meeting”) on November 6, 2023:

***

Fellow Stockholders,

The Radoff-Sudbury Group represents the largest stockholder of LifeVantage, meaning our interests are squarely aligned with yours. We believe replacing certain long-tenured directors with stockholder-nominated directors who possess CEO-level transformation, wellness industry and corporate governance experience can help ignite a lasting turnaround following a decade of poor performance. Ahead of next week’s Annual Meeting, we want to emphasize the opportunity you have to facilitate long-overdue change at LifeVantage by electing the right directors.

While we attempted to engage privately with the Board of Directors (the “Board”) on ideas for creating value and a settlement, we have been met with sustained resistance. The Company made clear it was not open to welcoming new perspectives to the Board until 2027, which we believe is indicative of the tight grip that Chairman Garry Mauro and other over-tenured directors have on LifeVantage. That is why we have invested a significant amount of our time and capital to nominate a minority slate of individuals with highly relevant skillsets to address the Company’s most urgent needs.

As detailed below, we are seeking to remove Chairman Mauro, Michael Beindorff and Darwin Lewis from the Board due to their excessively long tenures, track records of value destruction and lack of relevant experience. We are asking for your support to elect our three independent nominees, who are committed to putting LifeVantage stockholders’ long-term interests first.

We believe the choice is clear: voting the BLUE Proxy Card for the entire Radoff-Sudbury Group slate can help ensure the Board begins to act on behalf of all LifeVantage employees, consultants, stockholders and stakeholders.

We sincerely appreciate the thoughtful conversations and feedback we have received from you in recent weeks. If you have any further questions for us or would like to speak directly with our nominees, please contact our proxy solicitor at info@saratogaproxy.com.

Sincerely,

***
