Reaffirming 2024 Adjusted EBITDA and Free Cash Flow before Growth guidance ranges and capital allocation policy

NRG Energy, Inc. (NYSE:NRG) today reported Net Income for the three months ended December 31, 2023 of $482 million and a full year Net Loss of $202 million. The Net Loss was driven by unrealized non-cash mark-to-market losses on economic hedges due to large movements in natural gas and power prices. Adjusted EBITDA for full year 2023 was $3.3 billion, Net Cash Used by Operating Activities was $221 million, and Free Cash Flow Before Growth (FCFbG) was $1.9 billion.

"We delivered very strong financial performance in 2023," said Larry Coben, NRG Chair, Interim President and Chief Executive Officer. "The Company is well positioned for 2024 and ahead of pace against the plan we laid out at our June 2023 Investor Day. We remain focused on executing against our consumer and capital allocation strategy."

NRG is reaffirming its 2024 guidance ranges of $3,300 to $3,550 million in Adjusted EBITDA and $1,825 to $2,075 million in Free Cash Flow before Growth. The Company returned approximately $1.5 billion in share repurchases and common stock dividends in 2023 and remains committed to a capital allocation framework that is expected to return almost $5.5 billion over the next four years.

NRG's full year 2023 Adjusted EBITDA and FCFbG grew significantly compared to 2022, due to strong consolidated financial and operational performance across the Company.

The energy platform performed above plan, delivering strong customer count and product margins. In addition, the diversified supply portfolio benefited from targeted reliability investments in the generation fleet, resulting in approximately 15% annualized improvement on In-the-Money Availability, stabilizing and reducing supply costs despite volatile load and power price conditions in Texas. Since joining the NRG platform in March 2023, Smart Home has exceeded performance targets with increased average monthly recurring revenue, products sold per subscriber, and subscriber count.

Reaffirming 2024 Guidance

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

Table 2: Adjusted EBITDA, Cash Provided by Operating Activities, and FCFbG Guidance^a

		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.

Capital Allocation

The Company's long-term capital allocation policy is to target approximately 80% of recurring cash available for allocation (CAFA), after debt reduction consistent with achieving targeted credit metrics by 2025, to return of capital, and approximately 20% to strategic growth investments. As part of this plan, the Company expects to increase its dividend per share by 7-9% annually, complete its $2.7 billion share repurchase authorization, and reduce debt by up to $2.55 billion by year-end 2025.

In 2023, the Company returned approximately $1.5 billion to shareholders and paid down debt by $1.52 billion. NRG exceeded its original share repurchase target by $150 million and debt reduction target by $120 million. The Company returned $1.15 billion through share repurchases and returned $347 million in common dividends representing $1.51 per share. The Company's $950 million accelerated share repurchase program executed in the fourth quarter of 2023 is planned to conclude by the end of the first quarter of 2024, at which time the Company expects to enter into a new share repurchase program.

For 2024, the Company reiterates its previously announced capital allocation plan that includes $500 million in debt paydown, $825 million in share repurchases, and an 8% increase of the annual common dividend.

On January 19, 2024, NRG declared a quarterly dividend on the Company's common stock of $0.4075 per share, or $1.63 per share on an annualized basis. This represents an increase of 8% to the annual common dividend for the fifth consecutive year.

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.

NRG Strategic Developments

$550 Million 2023 - 2025 Growth and Cost Initiatives

The Company has identified select growth and cost opportunities throughout the business totaling $550 million of accretive and recurring FCFbG through 2025. These opportunities are comprised of $300 million of planned growth leveraging the capabilities of the Energy and Smart Home platforms, and $250 million of cost efficiency initiatives. As of December 31, 2023, NRG achieved approximately $100 million of the $300 million growth plan and achieved approximately $40 million of the $250 million cost initiatives.

Brownfield Generation Development

NRG continues to evaluate brownfield development opportunities at three of its existing generation sites in Texas, totaling up to 1.5 GW of dispatchable, natural gas fired capacity. The Texas Energy Fund, a low-cost Texas loan program to facilitate dispatchable new build generation, was formally approved in November 2023. NRG is awaiting the issuance of the Texas Energy Fund's rules and regulations.

Virtual Power Plant Opportunity

NRG is uniquely positioned to leverage its customer portfolio, product ecosystem, and market expertise in expanding access to Virtual Power Plant (VPP) opportunities. Demand response and management will continue to be a strategic priority in 2024.

a. Includes Corporate segment

b. Vivint Smart Home acquired in March 2023

Net Income/(Loss) for the full year 2023 was $1.4 billion lower than prior year primarily driven by a $4.1 billion negative impact from higher unrealized non-cash mark-to-market losses on economic hedges due to large movements in natural gas and power prices. Certain economic 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 non-cash losses or gains on the economic hedges that are not reflective of the expected economics at future settlement. Partially offsetting these losses were the gain on sale of the Company's 44% equity interest in STP and gross margin expansion in Texas.

b. Vivint Smart Home acquired in March 2023

Texas: Full year 2023 Adjusted EBITDA was $1,692 million, $806 million higher than prior year. This increase was primarily driven by lower retail supply costs as a result of solid execution of NRG's diversified supply strategy and improved plant performance, coupled with higher revenue rates.

East: Full year 2023 Adjusted EBITDA was $780 million, $7 million higher than prior year. This increase was primarily driven by higher retail power margins, partially offset by the impact of asset retirements and lower natural gas gross margin.

West/Services/Other: Full year 2023 Adjusted EBITDA was $57 million, $149 million lower than prior year. This decline was primarily driven by lower average realized pricing at Cottonwood, timing of planned outages, and lower contributions from the services business.

Vivint Smart Home: Adjusted EBITDA was $753 million, with subscriber growth of 6% over 2022 and expanded monthly recurring service margin.
