Arch Coal, Inc. reports second quarter results


o        Net income of $2.1 million, or $.04 per share, vs. net income of $0.8
         million, or $.02 per share, in 2Q01
o        Adjusted EBITDA of $62.7 million, vs. $68.3 million in 2Q01
o        Total revenues of $374.5 million, vs. $368.6 million in 2Q01
o        Coal sales of 24.9 million tons, vs. 26.7 million tons in 2Q01

     St. Louis - Arch Coal,  Inc.  (NYSE:ACI)  today  announced  that it had net
income of $2.1 million, or $.04 per share, for its second quarter ended June 30,
2002. In the same quarter of 2001, Arch had net income of $0.8 million,  or $.02
per share.

     "Our  decision  to reduce  production  in  response to weak coal demand and
pricing  continues  to be the single most  significant  factor in our  financial
performance,"  said Steven F. Leer,  Arch Coal's  president and chief  executive
officer.  "We remain confident that this decision is in the best interest of the
company  and its  shareholders.  However,  it has had an  adverse  impact on our
financial performance during the first two quarters of the year."

     Arch had  announced in March that it would reduce  production at its mining
operations by an estimated 7% due to weak coal demand resulting from a very mild
winter and the U.S. economic downturn. In keeping with this announcement, Arch's
shipped volumes were down approximately 7% in the second quarter compared to the
same period of 2001.

     Late in the quarter,  Arch settled  certain coal  contracts with a customer
that was  unwinding  its coal  supply  position  and  desired  to buy out of the
remaining terms of those contracts. These settlements resulted in a pre-tax gain
of $5.6 million. Without the settlements,  Arch's results would have been within
the projected range announced by the company in April.

U.S. coal markets

     "Although    stockpiles    at    coal-fired    power   plants   remain   at
higher-than-optimal  levels, we are optimistic about the potential for a rebound
in  U.S.  coal  markets  in  the  near  future,"  Leer  said.   "Several  recent
developments  support that view. First,  above-average  temperatures  during the
first half of the summer have led to substantially higher air conditioning load,
which has likely  resulted in a draw-down of stockpiles.  The summer months have
been 19% warmer than normal when measured by cooling degree days.  Second,  U.S.
coal  production is down nearly 4% year to date through July 6, according to the
U.S. Energy Information Administration."

     Coal supply is likely to remain constrained in the near term, especially in
the  eastern  United  States,  Leer  added.  "Not  only  are  eastern  producers
struggling to remain profitable given recent spot coal prices, but they are also
facing challenges related to permitting,  trucking,  bonding,  access to capital
and insurance. Smaller producers continue to be most distressed."

     Given these trends,  and the  potential for a stronger U.S.  economy in the
year's second half, the prospects for better supply-demand  balance and stronger
coal pricing appear strong, according to Leer.

     "Although we are  continuing  to restrict  production,  we are seeing signs
that the market is progressing  towards a healthier  balance  between supply and
demand,"  Leer said.  In fact,  coal  prices have begun to move higher in recent

     "Spot  pricing for  eastern  coal has  strengthened  by $1 to $2 per ton in
recent  weeks,  and we expect  further  increases  as the summer wears on," Leer
said.  "In the west, we have committed in recent weeks  approximately  3 million
tons of Powder  River  Basin coal for  delivery  in 2003 or 2004,  at an average
price of approximately $7 per ton."

     Leer  noted  that  the  company  had   participated   in  recent   contract
negotiations  in a  limited  fashion  only.  "We are very  comfortable  with our
position  and feel no sense of urgency  to sign  contracts  at  current  pricing
levels," Leer said. "We continue to believe that the current market has far more
upside potential than downside."

Operating statistics

     Regional  analysis:  Of the 24.9 million tons of coal that Arch sold during
the second  quarter,  approximately  8.0 million tons  originated at its eastern
operations and 16.9 million tons originated at its western operations. Arch Coal
had an average  realized  sales  price of $14.40 per ton and  average  operating
costs of $13.67 per ton. The eastern  operations  had an average  realized sales
price of  $30.47  per ton and an  average  cost of  $29.12  per ton  during  the
quarter. The western operations had an average realized sales price of $6.85 per
ton and an average cost of $6.39 per ton during the quarter. (Western operations
data does not include the results of  65%-owned  Canyon Fuel  Company,  which is
accounted for on the equity method.)

     Expected  sales  volume for the third  quarter of 2002:  In the east,  Arch
expects to sell a total of  approximately  7.4 million tons of coal in the third
quarter of 2002 from its mines in Central  Appalachia,  excluding brokered tons.
In the west, Arch expects to sell  approximately  18 million tons of coal at its
Black Thunder mine in the Powder River Basin of Wyoming, and roughly 1.5 million
tons at the West Elk mine in Colorado,  excluding brokered tons. Total sales (on
a 100% basis) at Arch's 65%-owned Canyon Fuel operations in Utah are expected to
be approximately 3.4 million tons for the quarter.

     Financial:  Arch expects depreciation,  depletion and amortization to total
approximately $210 million for the full year. Capital  expenditures are expected
to total  approximately $150 million.  (Projections for depreciation,  depletion
and amortization and capital expenditures include Arch's ownership percentage in
Canyon Fuel Company.)

Looking ahead

     "While  we are  enthusiastic  about  recent  developments  in the  contract
market,  demand  for spot coal in the  year's  second  half  remains  relatively
light,"  Leer  said.  "As a  result,  we do not  expect  to  increase  shipments
significantly  during the third  quarter,  traditionally  our  weakest  earnings
period. At present, we expect roughly breakeven results for the third quarter."

     Regardless of spot market activity,  the fourth quarter should be stronger,
but the company is not yet prepared to project  earnings  for that period,  Leer
said. "We continue to take steps to maximize the  efficiency of our  operations,
without  compromising  our  ability  to return  our mines to  optimal  levels of
production when coal markets rebound," he added.

     Leer also  noted  that the  performances  of both the West Elk and  Samples
mines had improved  substantially  in the second quarter.  "We are  increasingly
confident that these mines have worked through their recent  challenges and will
once again make positive  contributions to the company's  financial results once
market conditions rebound," he said.

     "For the remainder of 2002, we will continue to ship most of our production
under  contracts  that were signed  during the latter  half of the 1990s,"  Leer
said.  "Over the next 18 months,  the vast majority of those contracts will roll
off. If we are able to replace those low-priced  contracts in an improved market
environment,  with  commitments  characterized  by the more favorable  terms and
pricing  that  the  market  currently  seems to be  indicating,  we  should  see
significant improvements in our financial results."

     Forward-Looking Statements:  Statements in this press release which are not
statements of historical fact are  forward-looking  statements  within the "safe
harbor" provision of the Private Securities Litigation Reform Act of 1995. These
forward-looking  statements are based on information currently available to, and
expectations and assumptions  deemed  reasonable by, the company.  Because these
forward-looking  statements  are  subject  to various  risks and  uncertainties,

These  expectations,   assumptions  and  uncertainties  include:  the  company's
expectation  of  continued  growth in the demand for  electricity;  belief  that
legislation  and  regulations  relating to the Clean Air Act and the  relatively
higher costs of competing  fuels will  increase  demand for its  compliance  and
low-sulfur  coal;  expectation of continued  improved market  conditions for the
price of coal;  expectation  that the company  will  continue  to have  adequate
liquidity from its cash flow from operations, together with available borrowings
under its credit  facilities,  to finance the company's working capital needs; a
variety of operational, geologic, permitting, labor and weather related factors;
and the other risks and  uncertainties  which are described from time to time in
the company's reports filed with the Securities and Exchange Commission.
