While this morning's CEO change came as a surprise given that Greg Lucier has only been at the helm for less than four news, new CEO Chris Barry's experience with robotics, acquisitions, and commercial expansion make him "well-equipped" to run NuVasive, Needham analyst Mike Matson tells investors in a research note. After speaking to management, the analyst believes Lucier stepping down is a voluntary move, which he thinks is supported by the fact that the executive is maintaining his position as Chairman. NuVasive, however, did not reiterate its guidance in today's announcement and as a result, investors are assuming the company misses and/or lowers its 2018 guidance, Matson says. While this could "clearly occur," today's selloff makes the shares "sufficiently de-risked," the analyst contends. He's a buyer on today's weakness and keeps a Buy rating on NuVasive with an $80 price target.
