IPG Photonics (IPGP -6.7%) continues to slump following its Q3 report. Though results beat estimates, the industrial laser maker is guiding for Q4 revenue of $140M-$150M and EPS of $0.65-$0.75, below a consensus of $156.3M and $0.81. IPG, which is heavily exposed to Europe and China, says its Q3 book-to-bill was below 1, and that macro pressures in "a few key geographies" are hurting sales. Rival Coherent (COHR -2.2%) is also lower. IPG's CC is underway (webcast). (PR)
