Jefferies analyst Brandon Couillard said SmileDirectClub's (SDC) plans to enter the U.S. in-office, doctor-directed channel for aligners opens a new potential source of unit growth for the company and might soften scrutiny from the "dental establishment". Meanwhile, the move creates more competition "noise" for Align Technology (ALGN), Envista (NVST) and Dentsply Sirona (XRAY) and could be a source of near-term volatility for those stocks, although he said there is "still a lot to be fleshed out." While he thinks the negative read-throughs "are obvious," he said some potential positives include the fact that SmileDirect confirmed that the in-office market is still very relevant and that he sees clear differentiation between the aligners offered by Align and Envista when compared to SmileDirect.
