Ramtron Reports First-Quarter 2011 Financial Results

COLORADO SPRINGS, Colo.--(BUSINESS WIRE)--April 21, 2011--U.S. semiconductor maker Ramtron International Corporation (Nasdaq: RMTR), a leading developer and supplier of ferroelectric-based low-power memory and integrated semiconductor products, today reported total revenue of $10.6 million for the first quarter of 2011, compared with $15.8 million for the same quarter last year. Net loss for the first quarter of 2011 was $2.4 million, or $0.09 per share, compared with a net income of $415,000, or $0.02 per share, for the first quarter of 2010. First-quarter 2011 results included stock-based compensation expense of $347,000, and an income tax benefit of $1.4 million.

“We made significant progress during the first quarter toward relieving our current supply constraints,” said Eric Balzer, Ramtron’s chief executive officer. “With our wafer capacity effectively doubling this quarter, we are now working to expand our test capacity to support the increased wafer volume. Once we bring our wafer production into equilibrium with our test capacity during the second quarter, we will be in a position to satisfy our solid backlog of orders and resume revenue growth.”

First-Quarter Highlights:

• Announced the appointment of industry veteran Ying Shiau as vice president of customer satisfaction, with responsibilities for directing Ramtron’s quality assurance program as well as managing the company’s product and test engineering organizations
• Announced the W-Family of F-RAM memory devices, which offer a wider operating voltage range and performance enhancements including a 25% to 50% reduction in active current requirements and serial devices with up to 20 times faster access
• Announced that the company’s MaxArias Wireless Memory products have been recognized with Electronic Products China magazine’s “Product of the Year” and Application of Electronic Technique (AET) magazine’s “2010 Top Product” awards

“Work on our new manufacturing line is going well,” Balzer continued. “Recent successes will allow us to more broadly sample pre-qualification devices to waiting customers. We are currently making what we believe are final improvements to the process, which will allow us to qualify the line for production.

“Based on the progress we have made to resolve supply chain issues and continued strong demand, we are confident that we will meet our guidance for revenue of $25 million for the first half of the year,” added Balzer. “However, R&D investments are expected to remain above historical levels as we work as quickly as possible to bring up our new manufacturing line. As a result we anticipate a break even or slightly profitable second quarter. Our outlook for the full-year remains unchanged with anticipated total revenue of $65 to $70 million and GAAP net income of $0.10 per share,” Balzer concluded.
