USEC Holds Annual Meeting of Stockholders

BETHESDA, Md. - USEC Inc. (NYSE: USU) today held its annual meeting of stockholders and reported on the American Centrifuge research, development and demonstration (RD&D) program being conducted at facilities in Ohio and Tennessee.

Stockholders voted by approximately 80 percent to approve a reverse stock split. Details regarding the reverse stock split can be found in a separate news release issued today and available at www.usec.com. 

John K. Welch, USEC president and chief executive officer, said the aftermath of damage to Japanese reactors following the March 2011 earthquake and tsunami is still affecting the nuclear fuel industry. Many Japanese reactors remain idle and prices for low-enriched uranium fuel have declined over the past two years due to oversupply in the market. But despite these near-term challenges, "Looking out in the longer term, we think our industry has a bright future."

Approximately 65 reactors are under construction worldwide, including four in the United States, and many of these international reactors will be completed over the next several years. More than 100 more reactors are on the drawing board, especially in China and emerging markets in Asia and the Middle East. "The American Centrifuge Plant will be coming on line at the right time to meet this new demand, and can be expanded in the future to meet growing demand in the 2020s," Welch said.

"As concerns about climate change grow, nuclear power remains the only carbon-free source of 24/7 base load electric power. Nuclear power needs to be part of the solution and part of the world's energy mix. The environmental community is waking up to this fact, and that recognition could help drive growth for our industry," Welch said. "It is our strong belief that American Centrifuge is the key to our future and its successful deployment will increase the value of the enterprise."

Welch noted that USEC has made substantial progress with a two-year, cost-sharing research, development and demonstration program designed to enhance the technical and financial readiness of the centrifuge technology. The company plans to update its application with the DOE Loan Guarantee Office later this year.

During the meeting, stockholders voted to reelect seven directors for a one-year term. Stockholders also approved an advisory resolution on executive compensation and ratified the appointment of PricewaterhouseCoopers as the Company's independent auditors for 2013. A stockholder proposal regarding executive compensation was supported by less than 20 percent of the votes cast. The specific voting results will be provided in a current report on Form 8-K.

USEC Inc., a global energy company, is a leading supplier of enriched uranium fuel for commercial nuclear power plants.
