Item 8.01 Other Events
NRG Energy, Inc., or NRG or the Company, is an integrated power company built on dynamic retail brands with diverse generation assets. The Company’s core business is the sale of electricity and natural gas to residential, commercial and industrial customers, supported by the Company's wholesale generation.
As part of perfecting the integrated model, in which the majority of the Company’s generation serves its retail customers, the Company began managing its operations based on the combined results of the retail and wholesale generation businesses with a geographical focus in 2020. As a result, the Company changed its business segments from Retail and Generation to Texas, East and West/Other beginning in the first quarter of 2020. The Company's updated segment structure reflects how management currently makes financial decisions and allocates resources.
The Company's businesses are segregated as follows:
•Texas, which includes all activity related to customer operations in Texas (previously included in the Retail segment), plant operations in Texas (previously included in the Generation segment) and market operations in Texas (previously included in both the Retail and Generation segments);
•East, which includes the remaining activity related to customer operations (previously included in the Retail segment) and all activity related to plant operations in the East (previously included in the Generation segment) and market operations in the East (previously included in both the Retail and Generation segments);
•West/Other, which includes the following assets and activities (all previously included in the Generation segment, except for the Home Solar assets that were previously included in the Retail segment): (i) all activity related to plant and market operations in the West, (ii) activity related to the Cottonwood power plant that was sold to Cleco on February 4, 2019 and is being leased back until 2025, (iii) the remaining renewables activity, including the Company’s equity method investments in Ivanpah Master Holdings, LLC and Agua Caliente, the remaining Home Solar assets and the NFL stadium solar generating assets, and (iv) activity related to the Company’s equity method investment for the Gladstone power plant in Australia; and
•Corporate activities.
The vast majority of the Company’s business is in Texas, where the Company’s generation supply is fully integrated with its retail load. In the East, the Company’s retail load is more disperse throughout the region and not fully integrated with the Company’s generation supply due to the location of its power plants in that region. In the West, the Company’s business is primarily generation supply.
The Company is filing this Current Report on Form 8-K to retrospectively revise historical information to correspond with this new segment structure. Included in Exhibit 99.1 to this Current Report on Form 8-K are retrospectively revised discussions within the following sections of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2019 filed with the Securities and Exchange Commission (“SEC”) on February 27, 2020 (the “2019 Form 10-K”) in order to align with the new segment structure:
•Part I, Item 1 — Business;
•Part I, Item 2 — Properties;
•Part II, Item 6 — Selected Financial Data
•Part II, Item 7 — Management’s Discussion and Analysis of Financial Condition and Results of Operations; and
•Part IV, Item 15 — Exhibits, Financial Statement Schedules, including a revised Report of Independent Registered Public Accounting Firm, Note 1, Nature of Business, Note 2, Summary of Significant Accounting Policies, Note 3, Revenue Recognition, Note 4, Acquisitions, Discontinued Operations and Dispositions, and Note 19, Segment Reporting, to the Company’s consolidated financial statements.
All other information in the 2019 Form 10-K remains unchanged. Also filed as Exhibit 99.2 to this Current Report on Form 8-K is unaudited quarterly financial information for the previously reported quarterly periods in the year ended December 31, 2019, which have been retrospectively revised to correspond with this new segment structure.
