USEC Receives Continued Listing Standards Notice from the New York Stock Exchange

USEC Inc. (NYSE:USU) today announced that it has received a continued
listing standards notice from the New York Stock Exchange (NYSE) because
the price of its common stock has fallen below the NYSE′s minimum share
price rule. The NYSE requires the average closing price of a listed
company′s common stock to be at least $1.00 per share over a consecutive
30 trading-day period.

The Company′s common stock continues to trade on the NYSE. Subject to
NYSE rules, the Company has six months from receipt of the notice to
regain compliance with the NYSE′s price criteria (or by no later than
the Company′s next annual meeting of shareholders if shareholder
approval is required, as would be the case to effectuate a reverse stock
split to cure the deficiency). The Company is currently in compliance
with all other NYSE listing rules.

USEC can regain compliance at any time during the six-month cure period
if on the last trading day of a calendar month during the cure period,
the company has a closing share price of at least $1.00 and an average
closing share price of at least $1.00 over the 30 trading-day period
ending on the last trading-day of that month or on the last day of the
cure period. The Company is evaluating its options to cure the price
deficiency, including a reverse stock split, which would require
shareholder approval at or prior to the Company′s next annual meeting of
shareholders.

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