Results and Provides 2022 Guidance Update

Increasing Full Year 2022 Adjusted EBITDA Guidance

August 16, 2022

HOUSTON--(BUSINESS WIRE)-- Archaea Energy Inc. (“Archaea,” “the Company,” or “we”) (NYSE: LFG), an industry-leading renewable natural gas (“RNG”) company, today announced financial and operating results for the second quarter and first half of 2022.

FINANCIAL HIGHLIGHTS

RECENT STRATEGIC ACCOMPLISHMENTS

CEO COMMENTARY

“Today we released operating and financial results for the second quarter and first half of 2022 that collectively reflect the hard work and dedication of the Archaea team over our short tenure as a public company,” said Nick Stork, Archaea’s Co-Founder and Chief Executive Officer. “The first half of this year was a crucial time in our pursuit of cementing a runway to successfully increase our estimated long-term production and annual earnings power. Moving forward, it is time for us to leverage the foundation we’ve established and successfully execute on our development plan. With every day that goes by, our team proves that we have positioned ourselves as a distinctive renewable energy platform that will continue to reshape the RNG industry.

We continue to see meaningful benefits from our optimization program, which has not only improved the operational performance of our existing RNG asset base, but has also substantiated key subsystems included within our Archaea V1 plant design. We have also made progress on our new-build projects, with an additional dairy digester RNG facility recently coming online. We are also seeing the increasing value of our differentiated commercial strategy amidst continued price volatility in the short-term transportation markets, as we have continued to sign additional long-term, fixed-price contracts. Our recently announced contracts with Énergir and UGI underscore the demand for sizable volumes of RNG that are structured in a way that caters to the specific energy needs and environmental goals of customers. Archaea remains one of the few RNG producers that can meet these demands.

I cannot overstate the transformative nature of the two strategic transactions we announced in the second quarter of this year. In July, we funded our first capital contribution to the Lightning Renewables JV, expanded the Lightning Renewables JV to a total of 40 projects with the Fort Wayne acquisition, and successfully closed the acquisition of INGENCO. We look forward to seeing the impact of both INGENCO and the Lightning Renewables JV on the future growth and success of our business. To position these assets and our broader project development backlog for continued execution, we successfully upsized and amended our credit facility and term loan despite today’s challenging capital markets environment. We believe that the over $600 million of incremental commitments from our lender group underscores confidence in our differentiated business model and ability to advance the development of our robust project backlog.

As I’ve mentioned already, our efforts during the second half of this year are focused on execution. We are ready to demonstrate our unmatched gas processing, project development, and operational expertise with the imminent unveiling and commissioning of our inaugural Archaea V1 plants, while also completing our near-term optimization projects. We are increasingly confident that Archaea V1’s standardized and modularized design will prove itself to be the cornerstone of our success by reducing project development costs and timelines and enabling more efficient operating performance. It is the collective responsibility of the Archaea team to execute on our mission to construct, commission, and operate these facilities.

Our team is proud of what we have achieved to date, and we are prepared to achieve the next important phase of our development program.”

SUMMARY AND REVIEW OF FINANCIAL RESULTS

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

RNG production sold for the three months and six months ended June 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 methane recovery and RNG production from completed optimization initiatives. RNG production sold for the six months ended June 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 six months ended June 30, 2022 was positively impacted by efficiency improvements across the asset portfolio and incremental production from our PEI Power facility. Electricity production sold for the six months ended June 30, 2022 was also negatively impacted by winter seasonality in the first quarter.

Revenues for the three months and six months ended June 30, 2022 were positively impacted by RNG production from Assai, strong market pricing of Environmental Attributes, natural gas, and electricity, and forward sales of certain Environmental Attributes which reduces market pricing risk. Net equity investment income for the three months and six months ended June 30, 2022 was positively impacted by lower income tax expenses in the second quarter compared to the first quarter of 2022.

Net income for the three months and six months ended June 30, 2022 was primarily driven by strong market pricing of Environmental Attributes, natural gas, and electricity, and gains from changes in fair value of warrant derivatives, partially offset by higher cost of sales due to higher gas costs, electric utility costs, and employee costs, as well as higher royalties due to higher energy revenues. Net income for the six months ended June 30, 2022 was also positively impacted by reduced general and administrative expenses in the second quarter compared to the first quarter due to reduced acquisition and other transaction costs and severance costs.

Adjusted EBITDA for the three months and six months ended June 30, 2022 was positively impacted by strong market pricing of Environmental Attributes, natural gas, and electricity, and to a lesser extent, negatively impacted by higher cost of sales and higher royalties as described above.

Timing Adjustment for a Settled RIN Transaction

Under generally accepted accounting principles (“GAAP”), the timing of revenue recognition for stand-alone Renewable Identification Numbers (“RINs”) sales contracts is tied to the delivery of the RIN to our counterparties and not the production of the RIN. The Company had approximately 3.0 million RINs generated by June 2022 RNG production that were delivered under forward RIN sale agreements in July 2022 at a weighted-average price of $3.15. To reflect this and match the RIN revenue to the month of production, the Company included a $7.0 million Adjusted EBITDA add-back (“Settled RIN adjustment”), which represents the net cash value (proceeds minus expenses) of this settled, forward sold RIN transaction. The related revenues and associated royalty expenses will be recognized in the third quarter of 2022. The Company anticipates the quarterly financial impact of these monetization timing delays to be mitigated over time as it continues to bring additional RNG facilities online and enter into new contracts.

COMPLETION OF AMENDMENT AND UPSIZE OF TERM LOAN AND REVOLVING CREDIT FACILITY

On June 30, 2022, the Company announced that it successfully closed an amendment to its Revolving Credit and Term Loan Agreement. Aggregate commitments now total $1.1 billion, an increase of approximately $630 million from the original facilities, and consist of a $400 million senior secured term loan credit facility and a $700 million senior secured revolving credit facility (together, the “Amended Facilities”). The interest rate for the Amended Facilities is equal to the secured overnight financing rate (“SOFR”) plus 275 basis points for the revolving credit facility and SOFR plus 325 basis points for the term loan credit facility. The Amended Facilities also include an uncommitted $200 million accordion feature. The maturity date of the Amended Facilities remains unchanged at September 15, 2026.

Available capacity under the Amended Facilities, along with available cash, were used to fund the Company’s acquisition of INGENCO and initial capital contribution to Lightning Renewables. Available capacity under the Amended Facilities is also expected to be used to fund capital expenditures related to the Company’s development plan and other permitted investments, to provide working capital, and for other general corporate purposes.

CAPITAL STRUCTURE AND LIQUIDITY

As of June 30, 2022, Archaea’s liquidity position was $861.4, consisting of cash and cash equivalents of $213.3 million, restricted cash of $21.9 million, and $626.2 million of available borrowing capacity under the revolving credit facility after taking into consideration outstanding letters of credit.

The Amended Facilities described above, along with the Company’s other existing sources of liquidity, are expected to be sufficient to fund the Company’s development capital needs for the foreseeable future, including capital expenditures related to Lightning Renewables, projects related to INGENCO, and core development projects, thereby eliminating the need for additional external capital in the near-term based on the Company’s current development plans and backlog.

Capital Investments

Total cash used in investing activities was $67.1 million for the three months ended June 30, 2022. Archaea spent $66.5 million on development activities. Development activities in the three months ended June 30, 2022 were related to construction and optimization across the Company’s various plants and projects in development. The Company also made contributions to equity method investments totaling $4.0 million and received return of investment in equity method investments of $3.3 million.

Total cash used in investing activities was $133.6 million for the six months ended June 30, 2022. Archaea spent $127.9 million on development activities and $7.0 million, net of cash acquired, primarily related to the acquisition of landfill gas right assets. Development activities in the six months ended June 30, 2022 were related to construction and optimization across the Company’s various plants and projects in development. The Company also made contributions to equity method investments totaling $8.0 million and received return of investment in equity method investments of $7.4 million.

Well-Positioned to Support Recent Increase in Debt Funding and Near-Term Leverage

The Company believes it is capable of supporting the near-term increase in its leverage profile as a result of its Amended Facilities. The Company’s long-term debt profile is supported by long-term, fixed-price contracts in place today, which have a weighted average remaining contract term of 18.7 years and cumulative fixed-price value of up to $6.5 billion over the remaining life of the contracts. This provides the Company with multi-decade visibility into a sizable, predictable cash flow profile that can readily service its near-term debt levels.

2022 FULL YEAR GUIDANCE

Archaea is increasing its Adjusted EBITDA and capital expenditures guidance for full year 2022. In addition, the Company is reaffirming its electricity production sold volumes guidance and reducing its RNG production sold volumes guidance for full year 2022. All guidance is current as of the published date and is subject to change.

Within the 2022 Adjusted EBITDA guidance range, the Company estimates that approximately 3.0 million MMBtu at the midpoint of its expected 2022 RNG production sold will be subject to market pricing in the second half of 2022. For the second half of 2022, the Company assumes D3 RIN prices of $2.85 to $2.95 per gallon ($33.42 to $34.59 per MMBtu⁸) for volumes expected to be subject to market pricing. For projections beyond the second half of 2022, the Company’s D3 RIN pricing assumptions remain unchanged at $1.50 per gallon ($17.59 per MMBtu).

Within its 2022 Adjusted EBITDA guidance range, the Company is also reaffirming its expected general and administrative expenses of approximately $55 million, which includes expected headcount additions related to the INGENCO acquisition and Lightning Renewables JV.

The Company is revising its expected 2022 RNG production sold guidance to 10.4 million to 11.4 million MMBtu due to winter weather and maintenance activities in the first half of 2022 and unanticipated delays in zoning at optimization sites with significant landfill gas being flared or combusted. These delays are expected to be mitigated in the near-term. Annualized production as of July 2022 was approximately 10 million MMBtu per year, without the impact of significant optimization and new build projects that are expected to be placed into service in the second half of 2022.

The Company’s 2022 capital expenditures projection increased by $70 million to $80 million to reflect the impact of favorable additions to its development backlog. Excluding the incremental capital expenditures from these future projects, and capital paid for acquisitions year to date 2022, Archaea does not expect any material changes to its previous baseline 2022 capital expenditures guidance range provided on March 17, 2022 of $255 million to $285 million.

At the midpoint of its guidance range, the Company continues to expect capital investments of approximately $130 million during 2022 for projects expected to be placed into service in 2022.

Reconciliation of Non-GAAP Measures

Adjusted EBITDA

The following table reconciles Adjusted EBITDA to net income (loss) for the three and six months ended June 30, 2022:

Adjusted EBITDA is commonly used as a supplemental financial measure by Archaea’s management and external users of its consolidated financial statements to assess the financial performance of its assets without regard to financing methods, capital structures, or historical cost basis. Adjusted EBITDA is not intended to represent cash flows from operations or net income (loss) as defined by GAAP and is not necessarily comparable to similarly titled measures reported by other companies.

Archaea believes Adjusted EBITDA provides relevant and useful information to management, investors, and other users of its financial information in evaluating the effectiveness of its operating performance in a manner that is consistent with management’s evaluation of financial and operating performance.

Adjusted EBITDA is calculated by taking net income (loss), before taxes, interest expense, and depreciation, amortization and accretion, and adjusting for the effects of certain non-cash items, other non-operating income or expense items, and other items not otherwise predictive or indicative of ongoing operating performance, including gains and losses on disposal of assets, impairment charges, debt forbearance costs, net derivative activity, non-cash share-based compensation expense, acquisition and other transaction costs, severance costs, and Settled RIN timing adjustment. Archaea believes the exclusion of these items enables investors and other users of its financial information to assess its sequential and year-over-year performance and operating trends on a more comparable basis and is consistent with management’s own evaluation of performance.

Adjusted EBITDA also includes adjustments for equity method investment basis difference amortization and the depreciation and amortization expense and income tax expense included in the Company’s equity earnings from its equity method investments. These adjustments should not be understood to imply that Archaea has control over the related operations and resulting revenues and expenses of its equity method investments. Archaea does not control its equity method investments; therefore, it does not control the earnings or cash flows of such equity method investments. The use of Adjusted EBITDA, including adjustments related to equity method investments, as an analytical tool should be limited accordingly.

A reconciliation of expected full year 2022 Adjusted EBITDA to net income (loss), the closest GAAP financial measure, cannot be provided without unreasonable efforts due to the inherent difficulty in quantifying certain amounts, including changes in share-based compensation expense, which is affected by factors including future personnel needs and the future price of our Class A Common Stock, and fair value of warrant derivatives, due to a variety of factors including the unpredictability of underlying price movements, which may be significant.
