TransUnion is a credit bureau that collects data about how people handle money and sells that information to lenders.
TransUnion makes money by knowing things about your money. If you have ever applied for a credit card, a car loan, or an apartment, there is a good chance a lender paid TransUnion to peek at your financial history first. The company gathers records on hundreds of millions of people — whether you pay your bills on time, how much debt you carry, whether you have missed payments — and packages that into credit reports and scores. Lenders, landlords, insurers, and even employers buy those reports to decide whether to lend to you, rent to you, or hire you. Think of it as a giant financial report card that almost every adult in America has, whether they know it or not.
The business splits into three main pieces. The biggest chunk, roughly half of revenue, comes from US Markets, where the core credit-reporting operation lives. A second piece, about a third, is International, running similar credit bureaus in the UK, India, Latin America, and elsewhere. The smallest but fastest-growing slice is a newer area built around identity theft protection, fraud detection, and marketing data — sold to both businesses and directly to consumers who want to monitor their own credit. That consumer side, with apps and subscription products, has become a steady source of recurring revenue. Roughly $4 billion in annual revenue comes in, growing in the mid-single digits, though results swing with how many loans banks are making; when lending slows, so does TransUnion.
The company started in 1968 as a railroad leasing business before pivoting into credit data, and it has grown largely by buying competitors and data firms around the world. Free cash flow is healthy, and management uses it to pay down debt from those deals, buy back shares, and pay a small dividend. The big recent story is regulation and technology: governments are watching credit bureaus more closely after errors in reports hurt consumers, and the whole industry is racing to add AI tools and alternative data, like rent payments, to judge people who lack traditional credit history. TransUnion's bet is that whoever holds the most complete picture of a borrower wins.
