Coal producer Peabody Energy Corp. booked a second-quarter attributable net loss of $1.54 billion, or a loss of $15.78 per share, swinging from a year-ago net profit of $37.1 million, or 34 U.S. cents per share.

Revenue plunged to $626.7 million from $1.15 billion, reflecting the impact of substantially lower shipments and weak pricing amid the COVID-19 pandemic. Adjusted EBITDA sank to $23.4 million from $230.0 million.

Peabody flagged a $1.42 billion impairment on its North Antelope Rochelle coal mine in Wyoming due to changes in multiple assumptions, including lower long-term natural gas prices, timing of coal plant retirements and continued growth from renewable generation.

Peabody said Aug. 5 that its full-year 2020 guidance targets remain suspended while it slashed its planned annual capital expenditures to $200 million.

The company sold 28.3 million tons of coal in the second quarter, declining from 39.4 million tons in 2019. Sales from the seaborne thermal segment fell to 4.6 million tons from 4.7 million tons, while seaborne metallurgical sales declined to 1.1 million tons from 2.1 million tons. Powder River Basin shipments dropped to 17.9 million tons from 25.0 million tons.
