Fire in BASF's German chemical plant, China resorting to factory shutdowns in a move to regulate environmental laws, and floods in the US have caused several supply-side disruptions for f lavors and fragrances (F&F) players like S H Kelkar (SHKL), with sourcing of raw materials like or ange oil, citral and Isoprenol being severely affected. BASF alone accounts for 20-25% of SHKL's RM requirements. While SHKL maintains a large stock of inventory, severe supply constraints could exert pressure on margins over the next 2-3 quarters. We, however, believe that margin compression will be partly offset by the shifting of production from the Netherlands facility to Vapi (likely to be completed by July/August 2018). We revise down our FY19 margin estimate by700bp to 18.4% at the operating level and by 800bp to 11.4% at the PAT level.
