--- title: "Aflac: Competitors & Industry Structure" description: "Aflac compared with companies that share its SEC industry classification: revenue, growth and margins from SEC filings, and how the peer group is chosen." canonical: https://www.getswoopr.com/stocks/companies/aflac/competitors/ source: "Swoopr Investment: https://www.getswoopr.com" --- # Aflac: Competitors & Industry Structure ## Direct Answer SEC EDGAR classifies Aflac under SIC code 6321 (Accident & Health Insurance). Among Swoopr's S&P 500 Equal Weight companies, 4 others share that classification; by latest reported revenue, Aflac ranks 1 of 5. A filing classification is a starting point: a company's real competitors depend on its segments, which its 10-K describes. ## How Does Aflac Compare With Its Peers? | Company | Revenue (latest FY) | Revenue growth | Operating margin | Net margin | | --- | --- | --- | --- | --- | | **Aflac (AFL)** | $17.2 billion FY2025 | -9.3% | n/a | 21.2% | | [Principal Financial Group (PFG)](https://www.getswoopr.com/stocks/companies/principal-financial-group/) | $15.6 billion FY2025 | -3.1% | n/a | 8.0% | | [Unum Group (UNM)](https://www.getswoopr.com/stocks/companies/unum-group/) | $13.1 billion FY2025 | 1.5% | n/a | 5.6% | | [CNO Financial Group Inc. (CNO)](https://www.getswoopr.com/stocks/companies/cno-financial-group-inc/) | $4.5 billion FY2025 | 0.9% | 12.3% | 5.1% | | [Porch Group Inc. (PRCH)](https://www.getswoopr.com/stocks/companies/porch-group-inc/) | $482 million FY2025 | 10.2% | 7.6% | -0.7% | 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. ## How Does Aflac Rank Among All SEC Filers in Its Industry Code? 5 companies with annual reports in Swoopr's SEC dataset share SIC code 6321 (Accident & Health Insurance), a wider group than the S&P 500 Equal Weight companies above. Ranks run from 1 (highest) and use each company's latest fiscal year, in U.S. dollars. | Measure | Aflac | Median of filers | Rank | | --- | --- | --- | --- | | Revenue | $17.2 billion | $13.1 billion | 1 of 5 | | Revenue growth | -9.3% | 0.9% | 5 of 5 | | Net margin | 21.2% | 5.6% | 1 of 5 | A SIC code reflects the filer's main business as the SEC records it, so the group mixes companies of very different size; the median is a better guide than the average, and a rank near the top by revenue says nothing about quality. ## Where These Numbers Come From Every figure on this page is a value Aflac reported in its own SEC filings, read from the SEC's XBRL data (accession 0001628280-26-011402 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 Aflac's competitors? Companies sharing Aflac's SEC classification (SIC code 6321 (Accident & Health Insurance)) include Principal Financial Group (PFG), Unum Group (UNM), CNO Financial Group Inc. (CNO), Porch Group Inc. (PRCH). Its 10-K names the competitors it considers most relevant. ### How does Aflac compare with its peers on margins? A margin comparison needs reported operating income for Aflac 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. ### How does Aflac rank among all companies in its SEC industry? Among 5 SEC filers under SIC code 6321, Aflac ranks 1 by latest revenue. ## References - [SEC EDGAR: AFLAC INC Form 10-K filed February 25, 2026](https://www.sec.gov/Archives/edgar/data/4977/000162828026011402/afl-20251231.htm) - [SEC EDGAR: AFLAC INC annual and quarterly filings](https://www.sec.gov/cgi-bin/browse-edgar?action=getcompany&CIK=4977&type=10-K) - [SEC: EDGAR application programming interfaces (XBRL frames and submissions data)](https://www.sec.gov/search-filings/edgar-application-programming-interfaces) ## Related Pages - [Aflac company dossier](https://www.getswoopr.com/stocks/companies/aflac/) - [Aflac financial metrics](https://www.getswoopr.com/stocks/companies/aflac/metrics/) - [Aflac financial risk indicators](https://www.getswoopr.com/stocks/companies/aflac/risks/) - [Aflac peer comparison](https://www.getswoopr.com/stocks/companies/aflac/competitors/) - [Aflac business model and revenue mix](https://www.getswoopr.com/stocks/companies/aflac/business-model/) - [Fundamental analysis guides](https://www.getswoopr.com/learn/fundamental-analysis/) **[Swoopr Editorial Team](https://www.getswoopr.com/authors/swoopr-editorial-team/)** Swoopr's editorial team produces independent investment education content reviewed for accuracy and clarity.
