and Reaffirms 2024 Financial Guidance

•Strong second quarter financial and operating performance resulting in GAAP Net Income of $738 million and Adjusted EBITDA of $935 million

•Completed comprehensive preventative maintenance program for ERCOT fleet, well-prepared going into summer season and beyond

•Announcing agreement to sell Airtron HVAC business at an accretive multiple

•Submitted applications to Texas Energy Fund for 1.5 GW of shovel-ready generation capacity

•Continued to execute on liability management and capital allocation priorities, including open market share repurchases of $176 million year to date

HOUSTON-August 8, 2024-NRG Energy, Inc. (NYSE: NRG) today reported second quarter 2024 Net Income of $738 million. Adjusted EBITDA for the second quarter was $935 million, Cash Provided by Operating Activities was $1,056 million, and Free Cash Flow Before Growth Investments (FCFbG) was $663 million.

"NRG's business and financial outlook has never been stronger," said Larry Coben, NRG Chair, President and Chief Executive Officer. "Our relentless focus on safe and reliable operations especially during peak summer and winter months, dedication to exceptional customer experiences, and disciplined execution of our strategy and capital allocation plans continue to position NRG for success."

Free Cash Flow Before Growth Investments (FCFbG)	$	663	$	425	$	623	$	628

NRG's second quarter 2024 Adjusted EBITDA increased by $116 million year-over-year. The East and West segments experienced margin growth from both power and natural gas as well as improvements in customer counts. This was partially offset by lower Texas results, primarily a result of asset sales in 2023 and comprehensive preventative maintenance outages undertaken in the quarter to prepare the fleet for extensive summer operations.

With the completion of a comprehensive outage and preventative maintenance program, NRG's portfolio is well-positioned for the summer months, and the company is focused on delivering top-tier energy and smart home services for its customers.

2024 Capital Allocation

NRG is committed to its disciplined capital allocation principles and maintaining a strong balance sheet. In the second quarter of 2024, the Company continued to opportunistically repurchase shares in the open market as part of its $2.7 billion authorization to be executed through 2025. Through July 31, 2024, NRG has completed $176 million of its $825 million share repurchase target for 2024.

During the first quarter, NRG began repurchases of its 2.75% Convertible Senior Notes due 2048 as part of its overall objective of prudent and proactive liability management. In the second quarter, NRG repurchased an additional $251 million in principal of these notes, bringing the aggregate repurchase amount to $343 million or approximately 60% of the original issuance. For the remainder of the Convertible Senior Notes outstanding, NRG has purchased capped call options to fully hedge the settlement price. Finally, in the second quarter NRG also repaid $600 million in aggregate principal amount of its 3.75% Senior Secured First Lien Notes due 2024.

On July 19, 2024, NRG announced its Board of Directors declared a quarterly dividend on the Company's common stock of $0.4075 per share, or $1.63 per share on an annualized basis. The dividend is payable on August 15, 2024, to stockholders of record as of August 1, 2024.

NRG's share repurchase program and common stock dividend are subject to maintaining satisfactory credit metrics, available capital, market conditions, and compliance with associated laws and regulations. The timing and amount of any shares of NRG's common stock repurchased under the share repurchase authorization will be determined by NRG's management based on market conditions and other factors. NRG will only repurchase shares when management believes it would not jeopardize the Company's ability to maintain satisfactory credit ratings.

Strategic Developments

Airtron HVAC Sale

On August 3, 2024 the Company entered into a definitive agreement to sell its Airtron HVAC business unit for $500 million, subject to standard purchase price adjustments. Airtron is a leading installer of HVAC systems for residential new construction homes and was acquired as part of the Direct Energy acquisition in 2021. The opportunistic divestiture at an accretive 8.6x multiple on 2023 Adjusted EBITDA will provide additional capital available for allocation in 2024. The transaction is subject to regulatory approval under the Hart Scott Rodino Act and is expected to close by the end of 2024.

Texas Energy Fund

NRG has submitted applications to the Texas Energy Fund to request funding for three prospective brownfield development opportunities, totaling 1.5 GW of flexible, natural-gas generation in ERCOT. NRG's projects are shovel-ready, and assuming timely TEF approval, are expected to be completed for commercial operations between 2026 and 2028.

14th Annual Sustainability Report

NRG released its 2023 Sustainably Report, its 14th year of reporting, providing an update on the its commitment to people, environmental stewardship, and governance.

b Vivint Smart Home acquired in March 2023

Net Income for the second quarter of 2024 was $738 million, $430 million higher than the second quarter of 2023. This was primarily driven by higher unrealized non-cash mark-to-market gains on economic hedges in Texas in 2024 due to heat rate expansion in ERCOT, and losses in 2023 in the East due to declines in natural gas and power prices. This increase was partially offset by loss on debt extinguishment from the repurchase of the Company's 2.75% Convertible Senior Notes and higher income tax expense. Certain hedge positions are required to be marked-to-market every period, while the customer contracts related to these items are not, resulting in temporary unrealized losses or gains on the economic hedges that are not reflective of the expected economics at future settlement.

b Vivint Smart Home acquired in March 2023

Texas: Second quarter Adjusted EBITDA was $452 million, $52 million lower than the second quarter of 2023. This decrease was a result of asset sales in 2023 and the impact of an extended planned preventative maintenance program to ensure summer reliability, partially offset by gains in customer volumes from increased customer counts and favorable impact from weather.

East: Second quarter Adjusted EBITDA was $209 million, $132 million higher than the second quarter of 2023. This increase was driven by lower retail supply costs for power and natural gas and increased customer counts.

West/Services/Other: Second quarter Adjusted EBITDA was $73 million, $52 million higher than the second quarter of 2023. This increase was primarily driven by lower retail power supply costs and margin expansion at Cottonwood.

Vivint Smart Home: Second quarter Adjusted EBITDA was $201 million, $16 million lower than the second quarter of 2023. The decrease is attributable to guided increases in amortization of fulfillment expenses relating to the acquisition of Vivint by NRG. Absent this change, Adjusted EBITDA would have shown an increase year-over-year, supported by 5% growth in subscriber count and 4% growth in service margin.

As of June 30, 2024, NRG's unrestricted cash was $376 million and $5.0 billion was available under the Company's credit facilities. Total liquidity increased to $5.3 billion, increasing $499 million from the end of 2023, largely due to the $900 million increase in the Receivables Facility in the second quarter of 2024 and partly offset by the expiry of the $150 million Repurchase Facility.

Reaffirming 2024 Guidance

NRG is reaffirming its Adjusted EBITDA and FCFbG guidance for 2024 as set forth below.

Table 5: Adjusted EBITDA, Cash Provided by Operating Activities, and FCFbG Guidancea

2024
($ in millions)	Guidance
Adjusted EBITDA	$3,300 - $3,550
Cash Provided by Operating Activities	$1,825 - $2,075
FCFbG	$1,825 - $2,075

a Adjusted EBITDA and FCFbG are non-GAAP financial measures; see Appendix Table A-8 for GAAP Reconciliation. Adjusted EBITDA excludes fair value adjustments related to
derivatives. The Company is unable to provide guidance for Net Income due to the impact of such fair value adjustments related to derivatives in a given year. Cash Provided by
Operating Activities does not include changes in collateral deposits in support of risk management activities which are primarily associated with fair value adjustments related to
derivatives

Earnings Conference Call

On August 8, 2024, NRG will host a conference call at 9:00 a.m. Eastern (8:00 a.m. Central) to discuss these results. Investors, the news media and others may access the live webcast of the conference call and accompanying presentation materials through the investor relations website under "presentations and webcasts" on investors.nrg.com.

Appendix Table A-9: Actual Full Year 2023 Adjusted EBITDA Reconciliation for Airtron

The following table summarizes the calculation of Adjusted EBITDA and provides a reconciliation from Net Income:

Depreciation and amortization	28
EBITDA	57
Other costs	1
Adjusted EBITDA	$	58

EBITDA and Adjusted EBITDA are non-GAAP financial measures. These measurements are not recognized in accordance with GAAP and should not be viewed as an alternative to GAAP measures of performance. The presentation of Adjusted EBITDA should not be construed as an inference that NRG's future results will be unaffected by unusual or non-recurring items.

EBITDA represents net income before interest expense (including loss on debt extinguishment), income taxes, depreciation and amortization, asset retirement obligation expenses, contract amortization consisting of amortization of power and fuel contracts and amortization of emission allowances. 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.

Because of these limitations, EBITDA should not be considered as a measure of discretionary cash available to use to invest in the growth of NRG's business. NRG compensates for these limitations by relying primarily on our GAAP results and using EBITDA and Adjusted EBITDA only supplementally. See the statements of cash flow included in the financial statements that are a part of this news release.

Adjusted EBITDA is presented as a further supplemental measure of operating performance. As NRG defines it, Adjusted EBITDA represents EBITDA excluding the impact of stock-based compensation, amortization of customer acquisition costs (primarily amortized commissions), impairment losses, deactivation costs, gains or losses on sales, dispositions or retirements of assets, any mark-to-market gains or losses from forward position of economic hedges, 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 provided by operating activities is a non-GAAP measure NRG provides to show Cash provided/(used) by operating activities 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, changes in the nuclear decommissioning trust liability, and the impact of extraordinary, unusual or non-recurring items. The Company provides the reader with this alternative view of Cash provided/(used) by operating activities 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 Flows from Operating Activities 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 Flows from Investing Activities.

Free Cash Flow before Growth Investments is Adjusted Cash provided by operating activities less maintenance and environmental capital expenditures, net of funding and insurance recoveries related to property, plant and equipment, dividends from preferred instruments treated as debt by ratings agencies, 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 Investments as a measure of cash available for discretionary expenditures.

Free Cash Flow before Growth Investments is utilized by Management in making decisions regarding the allocation of capital. Free Cash Flow before Growth Investments 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 Investments is a performance measure and is not intended to represent Net Income/(Loss), Cash provided/(used) by operating activities (the most directly comparable U.S. GAAP measure), or liquidity and is not necessarily comparable to similarly titled measures reported by other companies.
