Among the companies with shares expected to actively trade in Tuesday's session are RadioShack Corp. (RSH), Coach Inc. (COH) and Yahoo Inc. (YHOO).

RadioShack swung to a wider-than-expected third-quarter loss as the consumer-electronics retailer's same-store sales declined and margins shrank. "Overall, our business performed below expectations," said interim Chief Executive Dorvin D. Lively. "I am most disappointed in our post-paid mobility business where we saw a continued decline in margin performance." Shares slumped 13% to $2.08 premarket.

Coach's fiscal first-quarter earnings rose 3% as a jump in international sales helped to keep its margins flat with the year-earlier period. Shares rose 6.4% to $57.65 premarket as the maker of high-end leather goods said its board also authorized the repurchase of up to $1.5 billion of stock by June 30, 2015. About $85 million remains under its prior repurchase authorization.

Yahoo posted a third-quarter earnings report Monday aimed at assuring investors the Internet company's core businesses have stabilized, and its new CEO offered a few details on the Silicon Valley standby's most-recent turnaround plan. Yahoo posted a big profit gain for the period, thanks to its sale of shares in Chinese Internet giant Alibaba Group Holding Ltd., but it showed tepid growth in its key business of online display advertising. Shares rose 4% to $16.40 premarket as results topped analyst expectations.

ARM Holdings PLC (ARMH, ARM.LN) said it has entered the fourth quarter with a record order backlog and a robust opportunity pipeline as the microchip designer posted a double-digit percentage rise in third-quarter revenue and profit, thanks to the rising popularity of smartphones and tablet computers. Shares rose 5.9% to $29.78 premarket.

E.I. DuPont de Nemours & Co.'s (DD) third-quarter earnings fell 98% as the diversified U.S. manufacturer saw its revenue fall and it was hit by large, one-time charges. Shares fell 5.6% to $47 premarket as results missed Wall Street expectations and the company slashed its full-year adjusted earnings outlook.

Autoliv Inc. (ALV, ALIV-SDB.SK), a Swedish automotive-safety company, cut its full-year earnings guidance as the accelerating decline in the European market and a customer labor strike in South Korea prompted a bigger-than-expected drop in third-quarter profits. Shares fell 7% to $59.20 premarket.

Western Digital's fiscal first-quarter profit more than doubled as hard-drive shipments continued to grow, though the company noted short-term demand weakness. However, Western Digital projected second-quarter earnings results below analyst expectations. Western Digital's shares fell 8% to $32.40 premarket while shares of competitor Seagate Technology Inc. (STX) declined 5% to $26.90.

Xerox Corp.'s (XRX) third-quarter profit shrank 12% as sales from the printing-and-services company's technology segment continued to wane. Shares fell 6.8% to $6.55 premarket as the company again lowered its earnings expectations for the year, and revenue fell below analyst estimates.

Veeco Instruments Inc.'s (VECO) third-quarter earnings plunged 62% as the company reported sharply lower revenue at its light-emitting-diode and solar business. Shares were down 4.6% at $27.56 in premarket trading Tuesday as the company projected fourth-quarter results well below Wall Street views and said it expects additional restructuring actions.

Rent-A-Center Inc.'s (RCII) third-quarter earnings jumped 28% as the provider of rent-to-own home-merchandise company continued to post double-digit percentage revenue growth at its RAC Acceptance arm. However, revenue growth missed analyst expectations.

Texas Instruments Inc. (TXN) said revenue dropped 2.2% in the third quarter as the sluggish global economy and the growing preference of big electronics manufacturers to make their own microprocessors weighed on demand.

United Parcel Service Inc.'s (UPS) third-quarter earnings fell 56% on pension-restructuring charges as the package-delivery company's revenue missed consensus estimates and margins shrank.
