Take a look at some of Tuesday's morning movers:
Alcoa - The Dow Jones Industrial Average component reported fiscal second-quarter profit of $0.06 per share, excluding certain items, one cent above estimates, with revenues also beating consensus. Despite a slump in aluminum prices to two-year lows, Alcoa said the fundamentals of the aluminum market remain sound.
Beazer Homes - Beazer has announced a $75 million stock offering, seeking to raise funds for general corporate purposes and to reduce debt. That represents a sizable offering, since the home builder’s current market capitalization is about $342 million.
Beazer is one of several companies announcing stock sale plans — others include Armour Residential REIT, DiamondRock Hospitality, OraSure Technologies, Senior Housing Properties Trust, and Synageva BioPharma.
Advanced Micro Devices - AMD is warning of weaker-than-expected sales for the second quarter. AMD now expects an 11 percent drop in revenues from the prior quarter, compared to its prior estimate of a 3 percent increase. The chipmaker blames “business conditions that materialized late in the second quarter” in China and in Europe.
Intel - Intel is buying a 10 percent stake in ASML Holdings, as it tries to bolster its efforts to create new tools for building computer chips. It’s also made a commitment to buy an additional 5 percent stake at a future date for about $1 billion. ASML is a maker of machines that print circuits on chips.
WD-40 - The company reported fiscal third-quarter profit of $0.57 per share, four cents below estimates. The maker of lubricants and cleaning products says it was hurt by lower sales in the U.S. market, and also says it expects full year profits to come in at the lower end of its prior guidance.
Jefferies Group - Jefferies is reporting another perfect trading quarter, reporting no days with trading losses for the 64 days contained in its fiscal second quarter. The news comes from a quarterly filing with the U.S. Securities and Exchange Commission.
Patriot Coal - The coal producer is filing for Chapter 11 bankruptcy protection, so it can proceed with what it calls a comprehensive financial restructuring. Patriot expects its mining and shipping operations to continue normally through the process.
Logitech - The maker of computer equipment is proposing a one-time dividend, subject to approval by shareholders at the September annual meeting.
Micron Technology - The chipmaker is running into some resistance to its deal to buy bankrupt Japanese rival Elpida memory for $750 million, with a group of Elpida bondholders saying they’ll vote against it. The group argues that Micron’s bid undervalues the company.
Verizon Communications - Verizon is reportedly about to receive approval for a controversial spectrum acquisition deal from the Federal Communications Commission, according to Reuters, but would still have to get an approval from the U.S. Justice Department. Verizon is planning to buy airwaves from cable companies including Comcast and Time Warner for about $3.9 billion.
Regis Corp. - The parent of the SuperCuts chain reported fiscal fourth quarter revenue of $568.1 million, below Street estimates of $579.7 million. Regis has been trying to cut costs amid a trend of customers lengthening time between haircut visits.
Mako Surgical - The surgical equipment maker cut its full-year guidance for sales of its Rio robotic arm, a device used by orthopedic surgeons. It now sees sales of 42 to 48 systems for the year, down from its prior projection of 52 to 58.
PriceSmart - The warehouse shopping club operator reported fiscal third-quarter profit of $0.52 per share, eight cents below estimates. PriceSmart did see increasing sales, but its profits have been hurt by rising merchandise costs.
Tyson Foods - The food producer's stock has been cut to "neutral" from "overweight" at JPMorgan Chase.
Wolverine Worldwide - The shoemaker reported fiscal second-quarter profit of $0.42 per share, two cents below estimates, with gross margins falling as well. Wolverine cites higher product costs and more clearance sales for the decline in margins. Those results could also impact stocks of Wolverine's direct competitors like Skechers, Deckers Outdoor, and Timberland.
