The following discussion of financial results exclude the impact from Winter Storm Uri:

Texas: First quarter Adjusted EBITDA was $254 million, $59 million higher than first quarter of 2020. This increase is driven by the acquisition of Direct Energy as well as lower supply costs, partially offset by a reduction of load due to weather.

East: First quarter Adjusted EBITDA was $266 million, $180 million higher than first quarter of 2020. This increase is driven by the acquisition of Direct Energy, prior year write-down of oil inventory by $29 million, and lower plant operating costs.

West/Services/Other: First quarter Adjusted EBITDA was $47 million, $21 million lower than first quarter of 2020. This decrease is due to the receipt of outage insurance proceeds in 2020 of $30 million and lower equity earnings due to the sale of Agua Caliente in February 2021, partially offset by an increase due to the acquisition of Direct Energy.

As of March 31, 2021, NRG cash was at $0.5 billion, and $2.7 billion was available under the Company's credit facilities. Total liquidity was $3.2 billion, including restricted cash. Overall liquidity as of the end of the first quarter 2021 was approximately $3.8 billion lower than at the end of 2020, driven by the closing of the $3.6 billion Direct Energy acquisition. As of May 4, 2021, NRG had $4.1 billion of liquidity available to continue to support its operations.

NRG Strategic Developments

Winter Storm Uri

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, 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.

During the quarter ended March 31, 2021, Winter Storm Uri's financial impact was a loss of $967 million. The impact is driven by resettlement data, ERCOT system wide counterparty defaults, provisions for credits losses, increased uplift charges to load, ancillary charges and other estimates including results from other regions. The Company expects the total 2021 loss before income tax to be $975 million, and a net cash flow impact of $350-550 million, after deducting $150 million of bill credits owed to large Commercial and Industrial (C&I) customers to be paid in 2022 and $275-475 million of estimated mitigants that the Company is pursuing. These potential offsets include, but are not limited to, customer bad debt mitigation, counterparty default recovery, ERCOT default and uplift regulatory securitization, and one-time cost savings.

In February 2021, NRG announced an initial $10 million commitment to provide relief for Texans impacted by the unprecedented effects of Winter Storm Uri. The relief effort included $3 million in cash donations and $7 million covering in-kind relief efforts and customer assistance. The funding addressed the immediate needs of the community, including food, water, and temporary or damaged housing; providing financial relief for customers through this difficult time; and aiding affected employees. Following the initial announcement, NRG provided additional tranches of financial support totaling over $1.5 million, volunteer support for several community events, and continues to provide assistance to customers.

Sale of 4.8GW of fossil generation assets in East and West regions

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.

The transaction is expected to close in the fourth quarter of 2021, and is subject to various closing conditions, approvals and consents, including Federal Energy Regulatory Commission (FERC), New York State Public Service Commission (NYSPSC), and antitrust review under Hart-Scott-Rodino Act.

Closed sale of remaining ownership in Agua Caliente

On February 3, 2021, the Company completed the sale of its remaining 35% ownership in the Agua Caliente solar project to Clearway Energy for $202 million.

Closed acquisition of Direct Energy

On January 5, 2021, the Company closed on the Direct Energy acquisition, paying an aggregate purchase price of $3.625 billion in cash, plus an initial 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, a $166 million draw on its corporate revolver, and approximately $2.9 billion in newly issued secured and unsecured corporate debt. In addition, the Company increased its collective liquidity and collateral facilities by $3.4 billion. The final purchase price adjustment resulted in a reduction of $38 million and the Company is expecting to receive this payment from Centrica during the second quarter.

The Company remains on track to achieve operational and cost synergies of $135 million in 2021 and an annual run-rate of $300 million to be achieved in 2023 by leveraging NRG's scalable operational platform and best-in-class cost discipline. This includes $51 million from realized synergies in the first quarter of 2021.

Today, NRG announced the designation of Houston, TX as the Company's sole Corporate Headquarters. The move to a single headquarters simplifies business operations, as a significant portion of the Company's employees and customers reside in Texas. NRG will maintain regional offices in the markets that it serves as the Company continues to grow. As the company makes progress against Direct Energy integration milestones, it will continue to evaluate real estate needs and consolidate as appropriate.

COVID-19

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. During 2020, summer-critical office employees returned to the offices and safety protocols were successfully implemented. The Company is currently planning to begin returning certain employees to the offices through a phased approach expected to be completed by the end of summer.

2021 Guidance Reinstated

NRG is reinstating guidance for Adjusted EBITDA, Adjusted Cash from Operations and Free Cash Flow before Growth Investments (FCFbG) for 2021 which excludes the full year impact of Winter Storm Uri.

Table 4: 2021 Adjusted EBITDA, Adjusted Cash from Operations, and FCFbG Guidance
		2021
(In millions)		Guidance
Adjusted EBITDA^a		$2,400 - $2,600
Adjusted Cash Flow From Operations		$1,630 - $1,830
FCFbG		$1,440 - $1,640

Non-GAAP financial measure; see Appendix Tables A-4 for GAAP Reconciliation to Net Income (Loss)/Income that excludes fair value adjustments related to derivatives. The Company is unable to provide guidance for Net Income (Loss)/Income due to the impact of such fair value adjustments related to derivatives in a given year

Capital Allocation Update

On April 19, 2021, NRG declared a quarterly dividend on the Company's common stock of $0.325 per share, payable on May 17, 2021 to stockholders of record as of May 3, 2021.

In light of the impact of Winter Storm Uri, the Company's deleveraging program will extend into 2022. The Company remains committed to maintaining a strong balance sheet and continues to work closely with rating agencies to achieve investment grade credit ratings.

The Company's common stock dividend and debt reductions are subject to available capital, market conditions, and compliance with associated laws and regulations.

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 (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 impairment losses, 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 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.
