•Reaffirming 2026 guidance ranges

•Advancing Bring Your Own Power strategy with hyperscaler for 1.2 GW CCGT in Texas

•Achieved commercial operations at 415 MW T.H. Wharton facility, NRG's first new build generation asset in nearly a decade; remaining two Texas Energy Fund projects on time and on budget

HOUSTON—August 4, 2026—NRG Energy, Inc. (NYSE: NRG) today announced financial results for the second quarter ended June 30, 2026, and reports GAAP Net Income of $506 million, GAAP Earnings per Share (EPS) — basic of $2.32, and GAAP Cash Provided by Operating Activities of $1,117 million. The Company's non-GAAP metrics are Adjusted Net Income of $315 million, Adjusted EPS of $1.49, Adjusted EBITDA of $1,217 million, and Free Cash Flow before Growth Investments (FCFbG) of $1,025 million for the second quarter of 2026.

"Today we provided a progress update on our Bring Your Own Power data center strategy," said Robert Gaudette, President & CEO. "This is the model for how large load growth should work. The customer supports the investment, with reliability and affordability protected for all. We also delivered a solid second quarter and are reaffirming our 2026 guidance. I am confident in the discipline and execution that continue to drive NRG forward."

a Adjusted Net Income, Adjusted EPS, Adjusted EBITDA, and FCFbG are non-GAAP financial measures; see Appendix tables A-1 through A-6 for GAAP reconciliations. Adjusted EPS, Adjusted Net Income, and Adjusted EBITDA exclude fair value adjustments related to derivatives

b Adjusted Net Income as shown here is 'Adjusted Net Income available for common stockholders'; see Appendix tables A-1 through A-4

c GAAP Net Income/(Loss) per Weighted Average Common Share - Basic

d Adjusted EPS calculated based on Adjusted Net Income divided by weighted average number of common shares outstanding - basic

NRG reported GAAP Net Income of $506 million for the second quarter of 2026, an increase of $610 million from the prior year. The improvement was due to the addition of the portfolio of assets acquired from LS Power and higher realized capacity prices in the East, partially offset by milder weather and higher supply costs. Results also benefited from unrealized, non-cash gains on economic hedges, primarily in the East, compared to losses in the prior year. These hedge positions are adjusted to market value each period, while the related customer contracts are not. As a result, the accounting treatment can result in temporary unrealized gains or losses that may differ from expected results when the contracts settle.

Adjusted Net Income for the second quarter 2026 is $315 million, $24 million lower than prior year, primarily driven by higher interest expense and depreciation and amortization related to the acquisition of the portfolio of assets acquired from LS Power, partially offset by a $308 million increase in Adjusted EBITDA, the impacts of which are described in the segment results below. Adjusted EPS is $1.49 for the second quarter 2026, $0.24 lower than prior year. The second quarter 2026 Adjusted EPS results include the financial impacts from Adjusted Net Income and impacts of shares issued as part of the completed acquisition of generation assets and CPower from LS Power.

Reaffirming 2026 Guidance

NRG is reaffirming its guidance for 2026 as set forth below.

Table 2: Adjusted Net Income, Adjusted EPS, Adjusted EBITDA, and FCFbG Guidance for 2026a

2026

(In millions, except per share amounts) Guidance

Adjusted Net Income $1,685 - $2,115

Adjusted EPS $7.90 - $9.90

Adjusted EBITDA $5,325 - $5,825

FCFbG $2,800 - $3,300

a Adjusted Net Income, Adjusted EPS, Adjusted EBITDA, and FCFbG are non-GAAP financial measures; see Appendix tables A-8 and A-9 for GAAP reconciliations. Adjusted Net Income, Adjusted EPS, and Adjusted EBITDA exclude fair value adjustments related to derivatives. The Company does not guide to GAAP Net Income due to the impact of such fair value adjustments related to derivatives in a given year.

2026 Capital Allocation

The Company plans to return $1.0 billion to shareholders through share repurchases and approximately $407 million through common stock dividends in 2026, as part of its previously announced 2026 capital allocation plan. Through July 31, 2026, the Company completed $932 million in share repurchases and distributed $202 million in common stock dividends.

On July 22, 2026, NRG declared a quarterly dividend of $0.475 per common share, or $1.90 per share on an annualized basis. The dividend is payable on August 17, 2026 to common stockholders of record as of August 3, 2026.

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 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.

NRG Strategic Developments

Advanced BYOP Data Center Strategy

NRG advanced its Bring Your Own Power (BYOP) strategy with a leading global cloud and AI hyperscaler. The parties are aligned on principal commercial terms for the development of a 1.2 GW combined cycle natural gas generation facility in Texas and remains subject to final documentation and approvals. This update highlights NRG's BYOP strategy of meeting large load growth through customer-backed generation investment to support grid reliability, energy affordability, and local communities.

Texas Energy Fund (TEF)

On May 26, 2026, NRG achieved commercial operations at its first project, the 415 MW T.H. Wharton facility. The project satisfied the eligibility requirements for the completion bonus grant program, and on June 17, 2026, the Company entered into a

completion bonus grant agreement with the PUCT for T.H. Wharton for up to $54.72 million, to be paid in ten annual installments, subject to performance of the facility, beginning after the initial test period ends on May 31, 2027. NRG's two additional TEF projects remain on time and on budget. Through the program, NRG plans to bring online a total of 1.5 GW of new, reliable, affordable power generation by mid-2028 to support the increasing energy demands of Texas consumers.

a Adjusted EBITDA is a non-GAAP financial measure; see Appendix tables A-1 through A-4 for GAAP reconciliation of Adjusted EBITDA (by operating segment) to GAAP Net Income (by operating segment). Adjusted EBITDA excludes fair value adjustments related to derivatives

b Includes Corporate activities

Texas: Second quarter 2026 Adjusted EBITDA was $381 million, $131 million lower than the prior year. For the first six months of 2026, Adjusted EBITDA was $597 million, $214 million lower than prior year. Results were primarily driven by higher supply costs, mild winter weather, including a ~30% decrease in heating degree days as compared to prior year leading to lower retail load, and additional operating expenses for the new generation assets.

East: Second quarter 2026 Adjusted EBITDA was $469 million, $370 million higher than the prior year. For the first six months of 2026, Adjusted EBITDA was $933 million, $360 million higher than prior year. Results were primarily driven by contribution of the new generation assets and CPower and higher capacity prices for owned generation, partially offset by higher power supply costs during Winter Storm Fern and lower natural gas margins.

West/Other: Second quarter 2026 Adjusted EBITDA was $66 million, $27 million higher than the prior year. For the first six months of 2026, Adjusted EBITDA was $172 million, $60 million higher than prior year. The increase was primarily driven by lower operating expenses associated with a lease expiration in May 2025.

Vivint Smart Home: Second quarter 2026 Adjusted EBITDA was $301 million, $42 million higher than the prior year. For the first six months of 2026, Adjusted EBITDA was $595 million, $56 million higher than prior year. The increase for both the quarter and the first six months of 2026 is attributable to higher new customer adds and an increase in monthly recurring service margin per customer.

Achieving investment grade credit metrics is not an indication of or guarantee that NRG

will receive investment grade credit ratings. Debt and share repurchases may be made from time to time subject to market conditions and other factors, including as permitted by United States securities laws. Furthermore, any common stock dividend is subject to available capital and market conditions.

Non-GAAP Financial Measures

NRG reports its financial results in accordance with the accounting principles generally accepted in the United States (GAAP) and supplements with certain non-GAAP financial measures. These measures are not recognized in accordance with GAAP and should not be viewed in isolation or as an alternative to GAAP measures of performance. In addition, other companies may calculate non-GAAP financial measures differently than NRG does, limiting their usefulness as a comparative measure.

NRG uses the following non-GAAP measures to provide additional insight into financial performance:

•Adjusted EBITDA: Defined as EBITDA (earnings before interest, taxes, depreciation, and amortization, impact of asset retirement obligation expenses and contract amortization consisting of amortization of power and fuel contracts and amortization of emission allowances) with further adjustments for stock-based compensation, 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, gains or losses on the repurchase, modification or extinguishment of debt, restructuring costs, and other non-recurring items plus adjustments to reflect the Adjusted EBITDA from our unconsolidated investments or non-controlling interests. Adjusted EBITDA is intended to facilitate period-to-period comparisons and is widely used by investors for performance assessment.

•Adjusted Net Income: Defined as net income available to common shareholders excluding the impact of asset retirement obligation expenses, contract amortization consisting of amortization of power and fuel contracts and amortization of emission allowances, stock-based compensation, 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, 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 and non-controlling interests.

•Adjusted Earnings per Share (EPS): Defined as Adjusted Net Income, divided by the average basic common shares outstanding.

•Adjusted Cash Provided/(Used) by Operating Activities: Defined as 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, adjustment for change in collateral, and the impact of extraordinary, unusual or non-recurring items.

•Free Cash Flow before Growth Investments: Defined as Adjusted Cash provided/(used) by operating activities less maintenance and environmental capital expenditures, net of funding and insurance recoveries related to property, plant and equipment, and adjustments to exclude cost of acquisition related to growth.

Management believes these non-GAAP financial measures are useful to investors and other users of NRG's financial statements in evaluating the Company’s operating performance and growth, as well as the impact of the Company’s capital allocation program. They provide an additional tool to compare business performance across periods and adjust for items that management does not consider indicative of NRG’s future operating performance. Management uses these non-GAAP financial measures to assist in comparing financial 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.
