If accurate, the EMS firms most likely to suffer would be Celestica (>10% of revenue comes from Cisco), Solectron (16%) and Jabil (15%).
Cisco forecast Q2 sales of $6.03 billion to $6.15 billion, lower than the Wall Street consensus of $6.21 billion.
Cisco's finished goods inventory increased during the last quarter to $714 million from $656 million. The company's book-to-bill is below 1.0, the mark of future expansion, Whitmore reported.
"[W]e expect soft trends in the communications infrastructure end market (for EMS vendors) to extend well into 2005. As such, we remain cautious on those EMS vendors with significant exposure to this end market," Whitmore said.
Solectron appears "most vulnerable" to softness at Cisco, Whitmore said.
