• Aiding Texas communities and performing root-cause analysis

• Significant advancement of customer-focused strategy:

  • Closed Direct Energy acquisition on January 5, 2021

  • Closed on sale of Agua Caliente on February 3, 2021

  • Announcing sale of 4.8GW of fossil generation assets

"Our priority today is both helping our Texas communities recover and working with all necessary stakeholders to improve the resilience of the energy system," said Mauricio Gutierrez, NRG President and Chief Executive Officer. "We continue to advance our customer-focused strategy with the completion of the Direct Energy acquisition and today's announced sale of 4.8 GW non-core fossil generating assets. Our integrated platform performed well in 2020 and continues to perform through unprecedented conditions, further validating our business model."

As of December 31, 2020, NRG cash was at $3.9 billion, and $3.1 billion was available under the Company's credit facilities. Total liquidity was $7.0 billion, including restricted cash. Overall liquidity as of year-end 2020 was approximately $4.9 billion higher than at the end of 2019, driven by $2.9 billion in financings and a $1.5 billion increase in credit facilities to fund the Direct Energy acquisition of which $1.4 billion was issued in the fourth quarter. The increases in credit facility and Put Option Agreement facility became available coincident with the closing of the Direct Energy acquisition. As of February 26, 2021, NRG had $3.8 billion of liquidity available to continue to support its operations.

During February 2021, Texas experienced unprecedented cold temperatures for a prolonged duration, resulting in a power emergency, blackouts, and an estimated all-time peak demand of 77 GWs (without load shed). Ahead of the event, NRG launched residential customer communications calling for conservation across all of its brands, and initiated residential and commercial and industrial demand response programs to curtail customer load. The Company maximized available generating capacity and brought in additional resources to supplement in-state staff with technical and operating experts from the rest of its U.S. fleet. NRG is committed to working with all necessary stakeholders on a comprehensive, objective, and exhaustive root cause analysis of the entirety of the energy system.

The estimated financial impact is still preliminary, due to customer meter and settlement data not being finalized, as well as potential customer and counterparty risk and expected ERCOT default allocations. Based on a preliminary analysis, Winter Storm Uri's financial impact is expected to be within NRG's current guidance range. The Company separately stress-tested assumptions and although at a lower probability, this stress-test analysis indicated a potential plus or minus $100 million to guidance ranges. NRG's integrated platform continues to deliver stable results through unprecedented events.

On February 28, 2021 the Company entered into a definitive purchase agreement with Generation Bridge, an affiliate of ArcLight Capital Partners, to sell approximately 4,850 MWs of fossil generating assets from its East and West regions of operations for total proceeds of $760 million, subject to standard purchase price adjustments and certain other indemnifications. As part of the transaction, NRG is entering into a tolling agreement for its 866 MW Arthur Kill plant in New York City through April 2025.

On January 5, 2021, the Company closed on the Direct Energy acquisition, paying an aggregate purchase price of $3.625 billion in cash, subject to a purchase price adjustment of $77 million. As part of the acquisition, Direct Energy had cash and margin collateral totaling $385 million. The Company funded the acquisition using $715 million of cash on hand, $166 million draw on its corporate revolver and approximately $2.9 billion in newly issued secured and unsecured corporate debt. In addition, the Company completed the expansion of its liquidity facilities by $3.4 billion.

NRG continues to remain focused on protecting the health and well-being of its employees, while supporting its customers and the communities in which it operates and assuring the continuity of its operations. In June 2020, summer-critical office employees returned to the offices and safety protocols were successfully implemented. The Company will continue to evaluate additional return to normal work operations on a location by location basis as COVID-19 conditions evolve.

On March 1, 2021, NRG will host a conference call at 9:00 a.m. Eastern to discuss these results. Investors, the news media and others may access the live webcast of the conference call and accompanying presentation materials by logging on to NRG's website at http://www.nrg.com and clicking on "Investors" then "Presentations & Webcasts." The webcast will be archived on the site for those unable to listen in real time.

NRG undertakes no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. The adjusted EBITDA and free cash flow guidance are estimates as of March 1, 2021. These estimates are based on assumptions the company believed to be reasonable as of that date. NRG disclaims any current intention to update such guidance, except as required by law. The foregoing review of factors that could cause NRG's actual results to differ materially from those contemplated in the forward-looking statements included in this presentation should be considered in connection with information regarding risks and uncertainties that may affect NRG's future results included in NRG's filings with the Securities and Exchange Commission at www.sec.gov.

EBITDA represents net income before interest (including loss on debt extinguishment), taxes, depreciation and amortization. EBITDA is presented because NRG considers it an important supplemental measure of its performance and believes debt-holders frequently use EBITDA to analyze operating performance and debt service capacity. EBITDA has limitations as an analytical tool, and you should not consider it in isolation, or as a substitute for analysis of our operating results as reported under GAAP. Some of these limitations are:

• EBITDA does not reflect cash expenditures, or future requirements for capital expenditures, or contractual commitments;

• EBITDA does not reflect changes in, or cash requirements for, working capital needs;

• EBITDA does not reflect the significant interest expense, or the cash requirements necessary to service interest or principal payments, on debt or cash income tax payments;

• Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and EBITDA does not reflect any cash requirements for such replacements; and

• Other companies in this industry may calculate EBITDA differently than NRG does, limiting its usefulness as a comparative measure.

Adjusted EBITDA is presented as a further supplemental measure of operating performance. As NRG defines it, Adjusted EBITDA represents EBITDA excluding impairment losses, gains or losses on sales, dispositions or retirements of assets, any mark-to-market gains or losses from accounting for derivatives, adjustments to exclude the Adjusted EBITDA related to the non-controlling interest, gains or losses on the repurchase, modification or extinguishment of debt, the impact of restructuring and any extraordinary, unusual or non-recurring items plus adjustments to reflect the Adjusted EBITDA from our unconsolidated investments. The reader is encouraged to evaluate each adjustment and the reasons NRG considers it appropriate for supplemental analysis. As an analytical tool, Adjusted EBITDA is subject to all of the limitations applicable to EBITDA. In addition, in evaluating Adjusted EBITDA, the reader should be aware that in the future NRG may incur expenses similar to the adjustments in this news release.

Management believes Adjusted EBITDA is useful to investors and other users of NRG's financial statements in evaluating its operating performance because it provides an additional tool to compare business performance across companies and across periods and adjusts for items that we do not consider indicative of NRG's future operating performance. This measure is widely used by debt-holders to analyze operating performance and debt service capacity and by equity investors to measure our operating performance without regard to items such as interest expense, taxes, depreciation and amortization, which can vary substantially from company to company depending upon accounting methods and book value of assets, capital structure and the method by which assets were acquired. Management uses Adjusted EBITDA as a measure of operating performance to assist in comparing performance from period to period on a consistent basis and to readily view operating trends, as a measure for planning and forecasting overall expectations, and for evaluating actual results against such expectations, and in communications with NRG's Board of Directors, shareholders, creditors, analysts and investors concerning its financial performance.

Adjusted cash flow from operating activities is a non-GAAP measure NRG provides to show cash from operations with the reclassification of net payments of derivative contracts acquired in business combinations from financing to operating cash flow, as well as the add back of merger, integration, related restructuring costs and changes in the nuclear decommissioning trust liability. The Company provides the reader with this alternative view of operating cash flow because the cash settlement of these derivative contracts materially impact operating revenues and cost of sales, while GAAP requires NRG to treat them as if there was a financing activity associated with the contracts as of the acquisition dates. The Company adds back merger, integration related restructuring costs as they are one time and unique in nature and do not reflect ongoing cash from operations and they are fully disclosed to investors. The company excludes changes in the nuclear decommissioning trust liability as these amounts are offset by changes in the decommissioning fund shown in cash from investing.

Free cash flow (before Growth) is adjusted cash flow from operations less maintenance and environmental capital expenditures, net of funding, preferred stock dividends and distributions to non-controlling interests and is used by NRG predominantly as a forecasting tool to estimate cash available for debt reduction and other capital allocation alternatives. The reader is encouraged to evaluate each of these adjustments and the reasons NRG considers them appropriate for supplemental analysis. Because we have mandatory debt service requirements (and other non- discretionary expenditures) investors should not rely on free cash flow before Growth as a measure of cash available for discretionary expenditures.

Free Cash Flow before Growth is utilized by Management in making decisions regarding the allocation of capital. Free Cash Flow before Growth is presented because the Company believes it is a useful tool for assessing the financial performance in the current period. In addition, NRG's peers evaluate cash available for allocation in a similar manner and accordingly, it is a meaningful indicator for investors to benchmark NRG's performance against its peers. Free Cash Flow before Growth is a performance measure and is not intended to represent net income (loss), cash from operations (the most directly comparable U.S. GAAP measure), or liquidity and is not necessarily comparable to similarly titled measures reported by other companies.
