Start Here ARCH COAL, INC. 2010 ANNUAL REPORT Start Here A recognized leader in mine safety and environmental compliance, St. Louis-based Arch Coal, Inc. (NYSE: ACI) is one of the world’s largest and most efficient coal producers, with more than 160 million tons sold in 2010. Through 11 mining complexes in six states, we represent roughly 15 percent of America’s coal supply. Our national scope of operations and 4.4-billion-ton reserve base includes a presence in five of six major U.S. coal supply basins. Our core business is supplying cleaner-burning, low-sulfur coal to customers on four continents, including U.S. and international power producers, industrial and other end users as well as steel manufacturers. It’s the start of a new decade, and coal’s story is as compelling as ever. Coal is the rock upon which the developed world’s economies were built – and it will continue to play a dominant role in powering the residential, commercial and manufacturing sectors of these economies for decades to come. In emerging markets, coal is the lifeblood supporting economic growth. It’s an essential input for steel making, an energy feedstock for industry and agriculture, and an abundant and affordable power source for electric grids around the world. Coal is playing a pivotal role in alleviating poverty, building the wealth of nations and advancing the quality of life for the world’s citizens. But coal’s story is also defined by its struggle to keep pace with demand. Many of the world’s traditional supply regions are facing reserve depletion, regulatory pressures and inadequate infrastructure investment. Overcoming these challenges – and bringing on new supply – will require long lead times and a massive capital outlay. These forces drive coal prices today … and will continue to influence coal markets in the decade ahead. 1 ARCH COAL, INC. 2010 ANNUAL REPORT Coal Is the World’s Energy Global coal consumption reached nearly 8 billion tons in 2010, having expanded by a record 3 billion tons in the past decade. China alone boosted its coal consumption from 1.3 billion tons in 2000 to 3.5 billion tons in 2010. Given current rates, global coal use could well increase another 3 billion tons in the next decade. In fact, by 2015, the world currently plans to add at least another 1.4 billion tons to annual coal demand.

A total of 425 giga- watts of new coal-based generating capacity is slated to come online by mid-decade, adding the equivalent of current U.S. coal industry production and more to global coal consumption. Beyond coal-based power plant additions, expected growth in per-capita steel consumption in developing economies will drive up demand for metallurgical coal in the coming years. Moreover, the adoption of plug-in electric vehicles in developed countries could accelerate the pull for steam coal in particular. +28 +114 +20 +516 +39 +352 * CHINA 2010 Market Size: 3,450 Million Tons Projected Growth: 352 Million Tons +211 INDIA 2010 Market Size: 690 Million Tons Projected Growth: 516 Million Tons MIDDLE EAST 2010 Market Size: 16 Million Tons Projected Growth: 20 Million Tons AFRICA 2010 Market Size: 214 Million Tons Projected Growth: 39 Million Tons OCEANIA/OTHER ASIA 2010 Market Size: 658 Million Tons Projected Growth: 211 Million Tons 3 ARCH COAL, INC. 2010 ANNUAL REPORT Strategic, Domestic Reserve Base Arch Coal’s reserves stretch nearly coast-to-coast, allowing us to meet future coal demand inside and outside America’s borders. Our coal shipments are regionally balanced across the nation’s four major railroads, while our investments in river terminals in Kentucky and Illinois grant us flexibility to transport coal on the nation’s inland waterways. In addition, our equity investments in marine terminals on the East and West Coast – along with throughput opportunities at ports in Virginia, Louisiana, California and British Columbia, Canada – provide access to the growing seaborne metallurgical and steam coal trade. million tons of reserves 455 16 million tons sold 2 3 4 5 1 WESTERN BITUMINOUS Arch is the largest coal producer in the Western Bituminous Region, comprised of Utah, Colorado and southern Wyoming. 1,353 million tons of reserves 1.

Over the past 13 years, the Powder River Basin has become the nation’s largest coal supply region, serving 48% of U.S. steam coal demand. Also, the Western Bituminous Region (representing 6% of U.S. steam coal output) is a key supply source for the Rocky Mountain area, which boasts the nation’s fastest-growing population. Additionally, both regions can further extend their reach into eastern U.S. states and globally. Arch also maintains a presence in key eastern coalfields. Although the nation’s No. 2 coal supply basin, Central Appalachia, is in secular decline – faced with depleting reserves and significant regulatory hurdles – it remains a strategic steam coal supply source for domestic and European power generators, and represents an important metallurgical coal supply source for global steel manufacturers. In addition, the Illinois Basin stands poised for resurgence as global steam coal demand rises and growth in world coal supply remains constrained. 2 1 ILLINOIS BASIN With a 49% equity interest in a private coal producer and a large, undeveloped reserve base in this basin, Arch has varied expansion opportunities it can pursue. 1.

In 2010, we set a new record for safety, attaining a lost-time incident rate of 0.46, the best in our history and the best among diversified U.S. coal industry peers. Last year, we also delivered our best environmental performance on record (as measured by SMCRA* violations). Achieving success in our core values of safety and environmental performance is absolutely critical for the overall success of our company. Of course, our ultimate goal is the “Perfect Zero” – zero injuries and zero environmental violations at each operation each and every year.

As more funds flow into clean energy programs, technology can and will deliver solutions to reduce greenhouse gas emissions, too. Given the rapidly expanding use of fossil fuels around the world, it’s imperative that investment in such technologies – like carbon capture and storage – increase. Arch supports clean coal technologies as part of our core values. We’re investing in a project that can turn coal into gasoline, with plans to capture the CO2 emissions from the proposed plant for use in enhanced oil recovery at domestic oil fields. We’re also financing and licensing technology aimed at reducing mercury emissions from coal. And, we’re mining and marketing predominantly low-sulfur coal to help limit traditional emissions at power plants. I R E D U C N G E M S S O N S I I ARCH COAL’S CLEAN COAL INVESTMENTS (in millions) >$50 Million Arch is helping advance the next generation of clean coal technologies by investing over $50 million in clean-energy innovators, university programs and public-private partnerships.

Our company delivered record free cash flow last year – a winning combination of improved earnings performance and restrained capital spending. Arch also achieved its second highest EBITDA in company history, driven by substantially higher operating margins in each region. More importantly, we expect 2011 to be even better.

The nearly $200 million spent on debt reduction last year helped the company lower its net-debt-to-capital ratio to 40%. Beyond building our balance sheet strength, we successfully completed a $500 million bond offering that extended a portion of our debt maturities out by seven years, from 2013 to 2020, providing additional financial flexibility. Arch is exceptionally well positioned in the U.S. coal industry with its delevered balance sheet and minimal level of legacy liabilities. As always, we’ll pursue organic growth opportunities that enhance our return on capital and evaluate strategic growth investments that create shareholder value – but we will do so prudently, as we’ve demonstrated over the course of our history. Absent those opportunities, we will look for ways to return our free cash flow to shareholders. 2008 $182 2009 $60 $3,186 million in reported revenues in 2010 – marking the best year in company history. 2010 $382 NET-DEBT-TO-CAPITAL RATIO (percent of total capital) ADJUSTED EBITDA* (in millions) 2000 2010 2000 2010 84% 40% $315 $724 9 ARCH COAL, INC. 2010 ANNUAL REPORT Dear Fellow Shareholders: The past decade has certainly been good financially for the U.S. coal industry and for coal stocks. Since 2000, an investment in ACI has returned 453% compared with a return of 15% for the S&P 500, highlighting our shareholder focus and five dividend increases during the past 10 years. Of course, other drivers contributed to this outperformance, including supply constraints, global economic growth and industrial expansion in emerging nations. So what will drive coal markets in the decade ahead? We believe it will be more of the same. Developed countries are finally rebounding from the Great Recession of 2009, while the developing world continues its rapid pace of economic growth, infrastructure spending and energy use. Coal industry consolidation, supply rationalization and reserve depletion will further shape future coal market dynamics. It’s still early in this global commodity super-cycle. We urge you to Start Here. It will be an exciting journey. 10 ARCH COAL, INC. 2010 ANNUAL REPORT FINANCIAL HIGHLIGHTS Year Ended December 31 (in millions, except per share data) Tons sold Revenues Income from operations Adjusted net income* 2010 162.8 2009 126.1 2008 139.6 $ 3,186.3 $ 2,576.1 $ 2,983.8 $ 324.0 $ 123.7 $ 461.3 $ 185.8 $ 63.4 $ 354.3 Adjusted diluted earnings per share* $ 1.14 $ 0.42 $ 2.45 Adjusted EBITDA* $ 724.2 $ 458.7 $ 753.2 Cash provided by operating activities $ 697.1 $ 383.0 $ 679.1 Capital expenditures $ 314.7 $ 323.2 $ 497.3 Dividends declared per common share $ 0.39 $ 0.36 $ 0.34 *Defined and reconciled at the end of this report.
