Oppenheimer analyst Kevin DeGeeter lowered his price target for Personalis to $26 from $29 following the company's Q3 earnings report, saying the company provided the first granular guidance on how to think about growth outlook for its two operating segments. While total revenue guidance is roughly in line with his prior outlook, DeGeeter tells investors in a research note that the segment growth outlook "deviated materially" from his forecast and Street consensus. The analyst revised his outlook for revenue to $64.8M, $80.1M and $101.5M from $62.2M, $82.0M and $124.2M for 2019, 2020 and 2021, respectively, and maintains an Outperform rating.
