Revenue growth compares each company's latest fiscal year with the one before. Fiscal years do not always end on the same date, so treat close comparisons with care.
Where These Numbers Come From
Every figure on this page is a value AES Corporation reported in its own SEC filings, read from the SEC's XBRL data (accession 0000874761-26-000063 for fiscal year 2025). Ratios are computed from those reported values. Figures were retrieved on October 7, 2026; a later amendment or a new annual report can change them, and the filing itself always takes precedence over this summary.
Each fiscal year is labeled by the calendar year in which it ended, so a company that names the same period differently in its own filings (many retailers whose year ends in January) may use another label. A year is left out of the table when the SEC data set holds no value for it. A figure shown as "Not reported" means the company did not file a value under the standard tag Swoopr reads, not that the amount was zero. This page is educational and describes reported history only; it is not a forecast or a recommendation.
Frequently Asked Questions
Who are AES Corporation's competitors?
Companies sharing AES Corporation's SEC classification (SIC major group 49) include Oneok (OKE), Duke Energy (DUK), NRG Energy (NRG), Southern Company (The) (SO), NextEra Energy (NEE). Its 10-K names the competitors it considers most relevant.
How does AES Corporation compare with its peers on margins?
A margin comparison needs reported operating income for AES Corporation and its peers; where either is missing, Swoopr leaves the comparison out.
How are these peers chosen?
By the SEC Standard Industrial Classification code each company files under, within Swoopr's S&P 500 Equal Weight company set, falling back to the two-digit major group when fewer than two companies share the exact code. Classification codes are broad, so read the peer list as a screen, not a verdict.
