As F5 (FFIV -6.8%) tumbles on news of sales chief Mark Anderson's resignation, UBS is slashing its estimates due to concerns about weak Euro demand. The firm notes EMEA accounts for ~20% of F5's sales, and recent downbeat comments from Cisco and Infoblox lead it to estimate F5's June quarter sales to the region will fall 5% Q/Q (other markets are expected to grow 5%). Piper aired similar commentary yesterday about rival Riverbed's (RVBD) Euro exposure.
