November 10, 2022

HOUSTON--(BUSINESS WIRE)-- Archaea Energy Inc. (“Archaea,” “the Company,” or “we”) (NYSE: LFG), one of the largest producers of renewable natural gas (“RNG”) in the U.S., today announced financial and operating results for the three and nine months ended September 30, 2022.

FINANCIAL HIGHLIGHTS

PENDING MERGER

In October, the Company announced that it has agreed to be acquired by bp (NYSE: BP) for $26 per share in cash, or a total enterprise value of approximately $4.1 billion, including approximately $800 million of net debt. Subject to regulatory approvals and Archaea shareholder approval, the parties are targeting closing the transaction (“the Merger”) by the end of 2022. In light of the transaction, the Company will not be hosting an earnings conference call or webcast to discuss its financial results and the Company will not be providing guidance for the fourth quarter or fiscal year 2022.

SUMMARY AND REVIEW OF FINANCIAL RESULTS

The following results for the three months and nine months ended September 30, 2022 are presented on a consolidated basis.

RNG production sold for the three months and nine months ended September 30, 2022 was positively impacted by incremental production from the Assai and Soares RNG facilities which were completed in December 2021 and January 2022, respectively, and increased uptime, methane recovery, and RNG production from certain plant optimization initiatives. RNG production sold for the nine months ended September 30, 2022 was also negatively impacted by downtime at certain facilities related to winter weather and maintenance activities during the first quarter.

Electricity production sold for the three months and nine months ended September 30, 2022 was positively impacted by efficiency improvements across the Company’s asset portfolio and incremental production from the INGENCO³ power assets after the acquisition closed in July 2022. Electricity production sold for the nine months ended September 30, 2022 was also negatively impacted by winter seasonality in the first quarter.

Revenues for the three months and nine months ended September 30, 2022 were positively impacted by RNG production from Assai, incremental electricity production from the INGENCO power assets, and strong market pricing of Environmental Attributes⁴, natural gas, and electricity.

Net loss for the three months and nine months ended September 30, 2022 was primarily driven by increased general and administrative expense, higher cost of energy due to higher gas costs, electric utility costs, and employee costs, as well as higher royalties due to higher energy revenues, partially offset by strong market pricing of Environmental Attributes, natural gas, and electricity. Expenses for the three months ended September 30, 2022 included $10.7 million for non-recurring legal and professional fees and other non-recurring costs primarily associated with the Merger, the formation of Lightning Renewables, LLC, and the acquisition of INGENCO. Net loss for the three months ended September 30, 2022 was also driven by losses from changes in fair value of warrant derivatives, and net loss for the nine months ended September 30, 2022 was also partially offset by gains from changes in fair value of warrant derivatives.
