Unfavorable product mix and the costs of integrating an acquisition led contract electronics manufacturer Three Five ( TFS) to widen its second-quarter loss estimate Friday.

The Tempe, Ariz., company expects to lose 31 cents or 32 cents a share in the three months to June 30 on revenue of $37.5 million to $38 million. Its old guidance was for a loss of 21 cents or 22 cents a share on revenue of $38 million to $40 million.

Analysts surveyed by Thomson First Call were forecasting a loss of 20 cents a share on revenue of $40.3 million. The stock was off 11 cents, or 2.6%, to $4.19.

The company blamed "product pricing and mix issues" in its Redmond facility and the integration of Integrex, a Washington-based electronic manufacturing services company whose customers TFS acquired during the first quarter of 2004.
