HOUSTON--(BUSINESS WIRE)--Feb. 28, 2024-- 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 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.

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.

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.

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 gain/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.
