SmileDirectClub Investor Presentation Deck

Q1 guidance & long-term outlook. We are managing the business to drive towards our long-term financial targets, which include 20- 30% revenue growth per year, and Adjusted EBITDA(¹) margins of 25-30%. For Q1 2021, we expect the following: ● smile DIRECT CLUB ● Revenue to be in line with our long-term targets on a sequential basis, meaning up 5-7% over Q4 2020. ● Adjusted EBITDA(1) to be profitable, but not necessarily focused to the level of Q4 2020, as we continue to ramp marketing spend in quarters like Q1 where the ad rates are lower and we can build our lead funnel, which we expect to pay off in future quarters. ● ● Our long-term objectives have not changed: We remain laser focused on providing the best club member experience, and our mantra remains to drive controlled and profitable growth. As a reminder, marketing dollars we spend today, have a long tail. Over 15% of our orders in Q4 became a lead at least 24 months ago. We remain the low-cost provider, with brand presence, no pricing pressure, and no real competitor that provides an end to end vertically integrated platform for the consumer. We will continue to make strategic investments in the professional channel, international growth, and in penetrating new demographics to drive controlled growth, all wrapped around continued spend on innovation and R&D. We continue to see favorable industry dynamics with broader acceptance of telehealth and specifically tele-dentistry, minimal penetration against our total addressable market, and clear aligners gaining share in the overall industry. All of these position us well for long-term success. (1) Adjusted EBITDA is a non-GAAP financial measure. See appendix for definition of Adjusted EBITDA. 17
