Shares of

UTStarcom

(UTSI) - Get Report

fell 30.7% after the maker of wireless gear warned of a big second-quarter shortfall and set plans to cut 17% of its workforce. The company posted first-quarter earnings of $38 million, or 29 cents a share, on sales of $901.9 million. The results easily outpaced analysts' expectations of 14 cents a share in earnings on sales of $800.8 million. The company's second-quarter outlook, however, spooked investors. The company forecast second-quarter sales of $740 million, well below the $844 million that analysts are expecting. UTStarcom blamed the shortfall on a faster-than-expected decline in sales of its personal wireless access systems in China. In an effort offset the weakness in China, the company said it would cut about 1,400 jobs. The restructuring is expected to cut operating expenses by about $40 million a quarter -- with the full effect realized by the fourth quarter of 2005. Shares traded down $3.21 to $7.24.
