FMI -5%/AH on 2017 guidance: http://investors.foundationmedicine.com/releasedetail.cfm?ReleaseID=1014009 Inasmuch as FMI announced “preliminary” 4Q16 results on 1/9/17 (http://investors.foundationmedicine.com/releasedetail.cfm?ReleaseID=1007033 ), the stock’s decline in AH trading is presumably due to the 2017 guidance rather than the 4Q16 results.
