Arch Coal, Inc. Reports Fourth Quarter Results

Highlights:

o Net income of $1.1 million, or $.02 per share, vs. net income of $8.4 million,
or $.16 per share, in 4Q01 o Adjusted EBITDA of $57.9 million, vs. $75.1 million
in 4Q01
o Total  revenues of $390.4  million,  vs. $385.4 million in 4Q01
o Coal sales of 28.4 million  tons,  vs. 28.5 million tons in 4Q01
o Debt  reduction of $51.5 million during the quarter

     St. Louis - Arch Coal,  Inc.  (NYSE:ACI)  today  announced  that it had net
income of $1.1 million, or $.02 per share, for its fourth quarter ended December
31, 2002. In the same quarter of 2001,  Arch had net income of $8.4 million,  or
$.16 per share.

     "We achieved solid operating performances at nearly all of our mines during
the fourth  quarter,  albeit at reduced  operating  rates," said Steven F. Leer,
Arch Coal's  president  and chief  executive  officer.  "We continue to see many
positive  signs  that  a  rebound  in  U.S.  coal  demand  and  pricing  may  be
forthcoming,  and we are managing our  operations in a manner that should enable
us to capitalize when that rebound occurs."

     During most of 2002, a weak economy and high coal stockpile  levels at U.S.
power plants exerted downward pressure on U.S. coal markets.  In response,  Arch
made the  strategic  decision in early 2002 to reduce  production  until  market
fundamentals  improved.  During the fourth  quarter,  lower  production  levels,
principally  at Arch's  eastern  operations,  again had an adverse impact on the
company's  results.  Offsetting  that impact  somewhat was a nearly  400,000-ton
increase  in  shipped  volumes  from the  company's  West  Elk mine in  Colorado
compared  to the same  quarter  of 2001.  (Production  at West Elk in the fourth
quarter of 2001 was  curtailed by high methane  levels.)  Brokered  volumes also
increased in the fourth quarter compared to the same period a year ago.


     For the year  ended  December  31,  2002,  Arch Coal had a net loss of $2.6
million, or $.05 per share,  compared to net income of $7.2 million, or $.15 per
share, in 2001.  Total revenues for the year totaled  $1,534.1  million and coal
sales totaled 106.7 million tons, vs. $1,488.7 million and 109.5 million tons in
2001.  Adjusted  EBITDA totaled $228.9 million for the year,  compared to $282.3
million in 2001.

Natural Resource Partners

     In  October,  Arch  completed  the sale of 1.9  million  units  of  Natural
Resource  Partners  (NYSE:NRP),  a newly formed joint venture  created to manage
coal royalty properties.  Net proceeds to Arch, after the underwriting  discount
and  expenses,  totaled  $33.6  million,  which were  applied to debt  reduction
efforts. The transaction is expected to be accretive to earnings. Arch continues
to hold 34.1% of the NRP  limited  partnership  units and 42.25% of the  general
partner interest.

     Using the funds from the sale of NRP units and cash  available from ongoing
operations, the company reduced its debt by $51.5 million, or 6%, from levels at
Sept. 30, 2002.

     Arch's continuing  interest in Natural Resource  Partners  contributed $2.3
million to equity  income  during the quarter.  (Arch's  equity  income from its
investment  in NRP is reported on a one-month  time lag and includes the effects
of Arch's  historical basis in the assets it contributed to NRP. As such, Arch's
equity  income from NRP may not be  indicative  of the results to be reported by
NRP for the noted  period.)  Offsetting the increase in equity income related to
NRP, equity income from Arch's 65%-owned Canyon Fuel Company declined from $11.9
million to $5.5 million, reflecting the expiration of a favorable sales contract
at the end of 2001 and a weak  market  environment  for Utah coal in the  fourth
quarter of 2002.

Operating statistics

     Regional  analysis:  Of the 28.4 million tons of coal that Arch sold during
the fourth  quarter,  approximately  7.7 million tons  originated at its eastern
operations and 20.7 million tons originated at its western operations. Arch Coal
had an average  realized  sales  price of $13.04 per ton and  average  operating
costs of $12.57 per ton. The eastern  operations  had an average  realized sales
price of  $29.93  per ton and an  average  cost of  $29.34  per ton  during  the
quarter. The western operations had an average realized sales price of $6.80 per
ton and an average cost of $6.36 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 first  quarter of 2003:  In the east,  Arch
expects to sell a total of  approximately  6.0 million tons of coal in the first
quarter of 2003 from its mines in Central  Appalachia,  excluding brokered tons.
In the west, Arch expects to sell approximately 16.0 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 3.7 million tons for the quarter.


     Financial:  Arch expects depreciation,  depletion and amortization to total
approximately $200 million for 2003. Capital  expenditures are expected to total
around $160 million,  as the company  continues to limit capital spending due to
the weak  market  environment.  (Projections  for  depreciation,  depletion  and
amortization and capital  expenditures  include Arch's  ownership  percentage in
Canyon Fuel Company.)

     Other developments:  During the quarter, the company reduced its days sales
outstanding in accounts receivable,  from 38 days at year-end 2001 to 33 days at
year-end 2002.

U.S. coal markets

     Although coal markets  remain under  significant  pressure,  there are many
positive  indications  that a recovery  in demand and pricing is possible in the
near term, Leer said. Among them:

o        Electricity demand is growing.

o        Many regions of the country, including the major coal-burning regions,
         have experienced substantially colder temperatures this winter compared
         to last winter.

o        Natural gas prices are trading at levels more than double those of a
         year ago, which should result in power producers seeking to maximize
         output at coal-fired power plants.

o        Coal production  declined by an estimated 2.5% in 2002, and
         announcements of eastern mine closures and curtailments have continued
         in recent weeks.

o        Extremely dry conditions in the western half of the country are
         threatening to reduce hydroelectric generation this spring and summer,
         which could boost demand for coal-fired generation.

     "We are already  seeing the first signs of a recovery in coal prices," Leer
said. "In recent weeks,  eastern spot prices have increased  approximately  10%,
although   volumes   remain  light.   If   temperatures   remain  at  normal  or
colder-than-normal levels for the remainder of the winter, and economic activity
does not falter, we anticipate a pick-up in demand for coal in the near term."

     Leer reiterated  that Arch is focused on being a market-driven  company and
would  not seek to  increase  output at its mines  until the  improving  pricing
environment attains levels that will allow satisfactory returns on the company's
investment. "In the current environment,  we believe it is in the best interests
of our  shareholders  to leave  uncommitted,  low-cost  reserves  in the ground,
rather than produce and sell them for little or no return," Leer added.


Looking ahead

     Leer said that the company is not expecting an improvement in its financial
results until coal markets  complete  their rebound.  "In the first quarter,  we
expect continued  stability and consistency at our mining  operations," he said.
"We expect sales volumes to be somewhat  lower than in the fourth  quarter as we
continue to refrain from  selling coal into the spot market,  and ship only that
tonnage which is already committed under contract."

     While results from mining  operations  are expected to be comparable in the
first quarter to those achieved in the fourth  quarter,  the company does expect
an increase in costs in 2003,  principally due to higher expenses related to its
post-retirement health care obligations. These obligations,  coupled with a much
smaller increase in pension-related  expenses, are expected to increase costs by
approximately $8.0 million per quarter,  reducing earnings by approximately $.12
per share. As a result,  the company expects to lose between $.05 and $.20 cents
per share during the first quarter of 2003,  absent  improvements in coal demand
and pricing in the near term.

     "Our projection for the first quarter assumes that shipping volumes will be
substantially  lower in the first quarter than in future  quarters,"  Leer said.
"If eastern  coal markets  continue  the trend of recent weeks by  strengthening
further,  and if western  markets  follow suit, we could see increased  shipping
rates and a stronger performance in the first quarter."

     "We are confident that power generators will require more coal in 2003 than
they currently have under  contract," he said.  "While we can't predict  exactly
when demand will accelerate,  market fundamentals continue to strengthen, and we
expect an  improving  market to have a  favorable  impact on sales  volumes  and
pricing as the year progresses."

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.

Adjusted EBITDA (A)                                              $   57,853     $    75,108     $   228,910     $   282,285

(A)  Adjusted EBITDA is defined as income from  operations  before the effect of
     net  interest  expense;  income  taxes;  our  depreciation,  depletion  and
     amortization;  and our equity interest in the  depreciation,  depletion and
     amortization of Canyon Fuel Company,  LLC. Adjusted EBITDA is not a measure
     of financial  performance in accordance with generally accepted  accounting
     principles, and items excluded to calculate Adjusted EBITDA are significant
     in understanding and assessing our financial condition. Therefore, Adjusted
     EBITDA should not be considered in isolation nor as an  alternative  to net
     income, income from operations,  cash flows from operations or as a measure
     of our  profitability,  liquidity or performance  under generally  accepted
     accounting  principles.  We believe that Adjusted  EBITDA presents a useful
     measure  of our  ability  to  service  and  incur  debt  based  on  ongoing
     operations.  Furthermore,  analogous measures are used by industry analysts
     to  evaluate  operating  performance.  Investors  should be aware  that our
     presentation of Adjusted  EBITDA may not be comparable to similarly  titled
     measures  used by other  companies.  The table below shows how we calculate
     Adjusted EBITDA.
