QUARTERLY REPORT December 2019 Highlights OPERATIONS ROM production for the December quarter was 6.6 Mt, down 12.8% on the previous quarter. ROM production for FY19 totalled 30.8 Mt, in line with the prior year. Saleable production for the December quarter was 4.6 Mt, down 12.4% on the September quarter. Total saleable production for FY19 was 20.2 Mt and in line with the prior year. Curragh total saleable production for FY19 was 12.5 Mt, up 3.2% on FY18. Reduced ROM and saleable production for the December quarter were due to higher inventories at US operations and an extended planned maintenance shutdown at Curragh. COAL SALES December quarter sales volumes of 4.7 Mt were down 5.1% on the previous quarter, primarily due to reduced sales from US operations as Atlantic Basin demand weakened and shipments to China were suspended. Total sales volumes for FY19 of 19.9 Mt were slightly below the previous year volumes of 20.2 Mt. Curragh FY19 sales volume of 12.8 Mt was 6.3% higher than FY18. Metallurgical coal as a proportion of saleable production was 80.9% for the December quarter and 83.7% for FY19, up 0.9% over the previous year. Export sales for the December quarter of 75.0% were in line with the previous quarter. Total export sales for FY19 of 75.7% was up 7.2% over the prior year. Group realised metallurgical coal price of $111.8 per tonne for the December quarter (average for all grades with a mix of FOR and FOB pricing) was down 11.2% compared to the prior quarter. FINANCIAL AND CORPORATE December quarter revenue was US$446 million (unaudited). FY19 revenue was US$2,216 million (unaudited), compared with US$2,296 million for FY18.

Message from the CEO Curragh Mine Incident As reported recently, the operations at the Curragh Mine were suspended on 12 January 2020 when a contractor was fatally injured during a tyre change activity in the main workshop on site. The Queensland Mines Inspectorate subsequently issued a directive that requires all relevant tyre and wheel rim fitting activities be suspended until the Inspectorate and Coronado are satisfied that these activities can recommence safely. Work at the mine recommenced gradually from Friday 17 January following return to work safety sessions involving all workers on site. At the time of writing, relevant tyre and wheel rim fitting activities have not yet recommenced. We extend our deepest sympathies to the family of the individual and all those affected by this tragic event. Our priority remains the welfare and safety of our employees and contractors and we continue to provide counselling and support. December Quarter and FY19 Performance Looking back, 2019 proved to be a year of two very different halves. A strong first half was followed by challenging market conditions in the second half. Against this backdrop, we are pleased that Coronado achieved ROM, saleable production and sales volumes that were on par with the previous year. Curragh ended the year with its best sales year on record, underpinned by further gains in the operational efficiency of our dragline fleet and enhanced CHPP reliability. The planned September maintenance shutdown at Curragh, which was extended into early October, helped us improve the overall reliability of the plant infrastructure. For our US operations, the December quarter was a challenging period on a number of fronts. A decline in demand from the Atlantic steel market, substantially lower spot metallurgical coal prices, coupled with the tariffs on US coal imports into China resulted in higher inventory levels and the suspension of shipments of Buchanan coal to China in October. As a result, the annual holiday shut down at Buchanan in December was extended to further reduce inventory while sales continued during this period. In anticipation of a trade resolution with China, two cargoes of Buchanan coal were loaded and sold in mid-November. In January 2020, the United States Government signed a Phase One trade deal with China that includes metallurgical coal exports. Whilst the details of the agreement and the impact on the tariffs on coal exports are yet to be clarified, there is now a clear path for export of Buchanan coal to China. This is likely to substantially reduce inventory levels at Buchanan and enable full scale mining operations to continue. During the quarter, demand for seaborne metallurgical coal continued to be influenced by port restrictions on Australian coal imports into China. As a result, the metallurgical coal market remained range bound between $130 to $140 per tonne during the December quarter. Due to weakened demand in the Atlantic market, we have committed a higher proportion of US production in 2020 to the domestic market. We continue to explore new marketing channels for our US coal brands into other markets by leveraging our existing global relationships and expect this initiative will generate new sales opportunities beyond 2020. Unaudited revenue for FY19 was $2,216 million. Strong coal pricing in the first half was offset by sustained lower pricing and difficult operating and trading conditions in the second half. Mining costs per tonne declined by 8.8% to $51.8 per tonne driven by operational improvements and efficiency gains at Curragh. Total saleable production for FY19 was 20.2 Mt, which was in line with FY18. The decision to suspend mining at the Toney Fork surface mine and commence production from new mining sources at Logan saw the proportion of metallurgical coal saleable production increase by 0.9% over the prior year. The 2019 financial year saw Coronado consolidate its operational asset base and build a solid platform for growth. Strong financial and operational performance underpinned shareholder distributions of $699 million during the year. The Curragh expansion plan remains on track and we continue to evaluate all opportunities to ensure our capital is employed efficiently. Whilst economic conditions remain challenging, we are well placed to deliver solid returns for shareholders in 2020. Gerry Spindler, Chief Executive Officer 2

Production and Sales Quarterly Production and Sales Performance (Unaudited) December quarter ROM coal production was 6.6 Mt, 12.8% lower compared to the September quarter due to the planned maintenance shutdown at Curragh extending into October. This resulted in reduced dragline exposure and coal mining for the quarter. ROM production at Buchanan was 1.4 Mt, 24.8% lower as high inventories of saleable production impacted stacking capacity. Logan’s ROM production was 1.3 Mt, down 22.2%, as operations were reduced in response to weakened demand from the Atlantic market. Saleable production for the Group of 4.6 Mt for the December quarter decreased by 12.4% compared to the September quarter. Saleable production at Curragh was 3.1 Mt, which was in line with the previous quarter. Buchanan’s saleable production of 0.9 Mt for the December quarter was 27.4% lower than the September quarter. Saleable production at Logan decreased by 27.8% on weaker Atlantic market demand and increased clean coal inventories. Metallurgical coal as a proportion of saleable production was 80.9% for the December quarter and 83.7% for FY19. December quarter sales volumes of 4.7 Mt were 5.1% lower than the September quarter volumes. Sales volumes at Curragh were 3.3 Mt, representing a 5.8% increase as availability of infrastructure improved following extensive planned maintenance in September/October. Sales volumes at Buchanan were 0.8 Mt or 21.7% lower compared to the previous quarter. Clean coal inventories remained high due to lower exports to China throughout the quarter. However, in mid-November two shipments were loaded and sold for delivery to China in anticipation of a Phase One trade deal being agreed. The Phase One trade agreement between China and United States was signed in January 2020. Logan’s sales volumes were 0.5 Mt, 19.0% lower than the September quarter. Lower demand from Atlantic Basin steel mills has resulted in higher port inventories and lower sales. The realised metallurgical coal price for Curragh was $119.7 per tonne (FOB) for the December quarter, a decrease of 12.5% compared to the previous quarter. The realised metallurgical coal price for the US operations of $96.6 per tonne (FOR) was 12.0% lower than the September quarter. 1 December 2018 Year-To-Date has been displayed on a Proforma basis 3 Summary InformationDec Q19Sep Q19 Change Dec 2019Dec 2018 YTDYTD1 Change ROM ProductionMt6.67.6 (12.8%) 30.830.7 0.2% CurraghMt3.73.8 BuchananMt1.41.9 LoganMt1.31.6 GreenbrierMt0.20.2 (2.0%) (24.8%) (22.2%) - 16.415.4 6.97.2 6.67.0 0.91.1 6.4% (4.4%) (7.0%) (10.1%) Saleable ProductionMt4.65.2 (12.4%) 20.220.2 0.3% CurraghMt3.13.1 BuchananMt0.91.2 LoganMt0.50.7 GreenbrierMt0.10.2 - (27.4%) (27.8%) (48.9%) 12.512.1 4.54.7 2.72.7 0.60.6 3.2% (4.8%) (2.0%) - % Met coal%80.9%83.7% (3.4%) 83.7%82.9% 0.9% Sales VolumesMt4.74.9 (5.1%) 19.920.2 -1.0% CurraghMt3.33.1 BuchananMt0.81.0 LoganMt0.50.6 GreenbrierMt0.00.1 5.8% (21.7%) (19.0%) (65.8%) 12.812.0 4.24.8 2.52.6 0.40.7 6.3% (13.0%) (4.0%) (36.0%) Sales Mix Met Coal%76.3%79.5% Thermal Coal%23.7%20.5% (3.9%) 15.2% 78.8%78.5% 21.2%21.5% 0.3% (1.2%) Export Sales%75.0%75.0% Domestic Sales%25.0%25.0% - - 75.7%70.6% 24.3%29.4% 7.2% (17.3) AU – Realised Met price (FOB)US$/t119.7136.8 Index PriceUS$/t140.1161.5 % of Index%85.4%84.7% (12.5%) (13.3%) 0.7% 140.4154.6 177.6206.8 79.1%74.8% (9.2%) (14.1%) 4.3% US – Realised Met price (FOR)US$/t96.6109.9 % of Index%68.9%68.0% (12.0%) 0.1% 111.3107.0 62.7%69.2% 4.0% (6.5%) Group - Realised Met priceUS$/t111.8125.9 % of Index%79.8%78.0% (11.2%) 1.8% 128.8133.3 72.5%86.2% (3.3%) (13.7%)

Q4 FY19 Sales Mix Q4 FY19 Export Mix 24% 25% 76% 75% Metallurgical Coal Thermal Coal Export Sales Domestic Sales Coronado’s proportion of metallurgical coal sales in the December quarter was 76.3% of the total sales mix. The decrease in metallurgical coal sales was a function of a higher proportion of thermal coal production at Curragh during the quarter. Export sales as a percentage of total sales for the December quarter was 75%, in line with the previous quarter. Financial and Corporate Unaudited December quarter revenue was $446 million. Total Group revenue (unaudited) for FY19 was $2,216 million compared to $2,296 million for FY18. Unaudited FY19 mining cost per tonne sold for the Group was $51.8 per tonne, 8.8% lower than in FY18. Mining costs per tonne was within the guidance range of $51/t to $52/t. Capital expenditure for FY19 was $184 million (unaudited). Capital expenditure was slightly higher than the FY19 guidance range ($160 million to $180 million) as a result of the development costs associated with the Stanwell Reserved Area. At 31 December 2019 the Company’s net debt position was $303 million. In December 2019, Coronado changed its registered office address to Level 33 Central Plaza One, 345 Queen Street, Brisbane QLD, 4001 Australia Coronado will release its FY19 results to the market on 25 February 2020. 4

Operational Overview Safety In Australia, the 12-month rolling sold and shipped two cargos of Buchanan coal to China in mid-November which will land in country in 2020. The Buchanan operation was partially idled over the Christmas holiday period to further manage inventory levels. Contracted sales were fulfilled from existing inventory. Buchanan commenced normal operations from January 2020 with no further delays in production anticipated for the first quarter of 2020. Logan ROM production at the Logan Complex was 1.3 Mt, average Total Reportable Injury Frequency Rate (TRIFR) at the end of the quarter was 6.5. In the US, where Buchanan achieved 1 million-man hours without a lost time incident, the Total Reportable Incident Rate (TRIR) for 12-month rolling average period was 2.14. Curragh The December 2019 quarter was impacted by the September CHPP maintenance shut down which extended into October and reduced expected saleable production. The planned maintenance shut down will result in further improvement in CHPP reliability. ROM production for the December quarter was 3.7 Mt, a reduction of 2.0%. Saleable production was 3.1 Mt, in line with the previous quarter. Sales volumes of 3.3 Mt were 5.8% higher than the prior quarter as availability of rail and port infrastructure increased following the scheduled maintenance in the September quarter. The realised metallurgical coal price for Curragh was $119.7 (FOB) for the quarter which was 12.5% lower than the previous quarter. This was a result of a moderation in the three-month lag pricing in which Curragh coal is priced. The Central Highlands region, where Curragh is located, is experiencing a significant dry period. Despite recent rainfall, Curragh is closely monitoring water supply and has prepared contingency plans in the event that its water allocation is reduced. Buchanan December quarter ROM production was 1.4Mt, 24.8% lower than the September quarter. The reduction was the result of higher inventory levels due to softening demand from Atlantic Basin steel mills and continued tariff implications resulting in lower export volumes into China. Saleable production was 0.9Mt, 27.4% lower compared 22.2% down on the September quarter. Saleable production during the December was 0.5 Mt or 27.8% lower than the September quarter. ROM and saleable production volumes were lower compared to the September quarter due to slowdown in operations driven by the softening demand from steel mills located in the Atlantic Basin. This resulted in a slowdown in vessel loadings and increase in port inventories. Coronado has concluded sales negotiations for HVA and HVB for 2020. Given the weakened demand from Atlantic Basin steel mills, a higher proportion of domestic US sales have been committed for Logan high vol products in 2020. Greenbrier ROM production at Greenbrier was 0.2 Mt, in line with the previous quarter. Saleable production of 0.1 Mt was 48.9% lower than the September quarter. Production was impacted by adverse geological conditions. Sales volumes were 65.8% higher than the previous quarter. to the September quarter. High inventory levels constrained stockpile space at the CHPP decreasing production levels.To manage inventory, Coronado 5

Steel demand in China is expected to be strong in 2020 as the Chinese Government has announced a stimulus package targeting infrastructure investment. It is expected the stimulus will be implemented post Chinese New Year in late February. Steel producers outside of China, in particular Japan, Korea, Brazil and Europe have been affected by a slowdown in the demand for steel.
