NEW YORK ( TheStreet) -- International Game Technology ( IGT) is plunging a day after it reported a disappointing outlook. The slot machine maker raised the low end of its full-year guidance, now expecting to earn 82 cents to 85 cents a share, from a previous range of 77 cents to 85 cents for IGT. But this still falls short of analysts' estimates of 89 cents a share. During the third quarter, IGT earned $92.1 million, or 31 cents a share, compared with $60.6 million, or 20 cents, in the year-ago period. Analysts expected a profit of 21 cents a share. IGT revenue fell 5% to $489.7 million from $517.3 million, missing Wall Street's consensus of $502 million. IGT saw weakness in its domestic operations. IGT is tanking 9.6% to $15.10, and weighing down stocks of other slot machine makers. WMS Industries ( WMS) is sinking 5.7% to $38.89, while Bally Technologies ( BYI)is losing 5% to $33.22. "We believe the macro story for the supplier sector is better than the individual at IGT," Sterne Agee analyst David Bain wrote in a note. But Bain reaffirmed his hold rating on the stock, with a positive broader view on gaming expansion opportunities and the likelihood for a slightly improved replacement cycle in 2011. Regardless, Bain says he still prefers WMS and Bally over IGT. -- Reported by Jeanine Poggi in New York. Follow TheStreet.com on Twitter and become a fan on Facebook.
