Walter Energy Provides Preliminary First Quarter 2013 Operating Results

Walter Energy, Inc. (NYSE: WLT) (TSX: WLT) today said that performance
for the first quarter 2013 has improved compared with fourth quarter
2012, driven largely by increased metallurgical coal sales volume and
pricing, increased production and lower costs.

'Improvements across our operations over the past several months reflect
the success of our ongoing initiatives,? said Walt Scheller, Chief
Executive Officer. 'Along with the progress we continue to make in our
operations, we are also pleased with the recent actions taken to
increase our financial flexibility. As to the current market, we have
seen stronger demand and improved pricing, with second quarter benchmark
prices of $172 per metric ton for hard coking coal and $141 per metric
ton for low vol PCI. We believe all these factors position us well as we
look ahead to the remainder of 2013.?

Metallurgical Coal Sales

Walter Energy expects to report first quarter 2013 metallurgical coal
sales volume of approximately 2.8 million metric tons, up approximately
9% compared with fourth quarter 2012. Average realized metallurgical
coal sales prices are also expected to improve slightly compared with
fourth quarter 2012, primarily due to a higher sales volume of low vol
hard coking coal and a slight strengthening in the market. The
improvement in pricing in the quarter was tempered by approximately
700,000 metric tons of carryover sales at fourth quarter 2012 pricing.

The Company also expects to report that metallurgical coal cash cost of
sales declined by over $10 per metric ton as compared with the fourth
quarter 2012, primarily driven by the higher proportion of low vol hard
coking coal sales from our Alabama operations and a substantial
improvement in cash cost of sales for low vol PCI.

Metallurgical Coal Production

First quarter 2013 metallurgical coal production is expected to total
approximately 2.8 million metric tons, up approximately 12% compared
with fourth quarter 2012. While production volumes early in the first
quarter reflected the impacts of planned long wall moves in the
Company′s Alabama operations, production performance improved in the
latter part of the quarter. Metallurgical coal cash costs of production
is expected to improve by approximately 5% compared with the fourth
quarter.

Thermal Coal Sales

Sales of thermal coal are expected to total approximately 380 thousand
metric tons in first quarter 2013, a decline of approximately 40% from
fourth quarter 2012. As a result of the lower volume, cash cost of sales
was higher by approximately $35 per metric ton during first quarter 2013
due to mining conditions at our North River mine. The Company announced
in first quarter 2013 that it would close this mine earlier than
previously planned and expects this closure to occur before year-end.

Senior Notes Offering

On March 27, 2013, Walter Energy announced the closing of its sale of
$450 million 8.5% senior notes. Proceeds were used to repay $250 million
of indebtedness outstanding under its credit facilities. The remainder
is being used to enhance current liquidity and ultimately is expected to
be applied against outstanding term debt. The Company believes that the
proceeds from this offering provide sufficient financial flexibility and
liquidity, and that it has no need to raise additional capital.

First Quarter 2013 Earnings Release and Conference Call

The Company plans to release its first quarter 2013 results and hold its
earnings conference call on May 2, 2013. Details of the timing of its
earnings release and conference call will be announced over the coming
weeks.
