EFX

Equifax sits in the second chair of a three-player oligopoly that controls the credit files on virtually every borrowing American — a business no one can replicate because you cannot build 1.4 billion credit records from scratch any more than you can rebuild the railroad network. But the crown jewel is not the credit bureau; it is The Work Number database covering 209 million active payroll records, which answers the question 'does this person actually earn what they claim?' in seconds at near-zero marginal cost, generating 51.5% EBITDA margins in a segment with no competitor of comparable scale. This is a toll booth on the mortgage closing process — every home purchase in America essentially pays Equifax for an income verification.

Mr. Market is pricing Equifax at 14.4x EV/EBITDA and implying just 5.5% perpetual FCF growth — roughly two-thirds of the 8.6% revenue CAGR the business has actually delivered over ten years. The catalyst is arithmetic, not faith: $714 million in annual D&A (up from $269M in 2016) must decline as $3B+ of cloud assets fully depreciate over the next 3-5 years, mechanically unlocking 400-600 bps of margin recovery even on flat revenue growth. FCF already inflected to $1.13B in FY2025 at 120% conversion, CapEx is declining from $625M peak to $481M, and the $928M in FY2025 buybacks signals management finally pivoting from reinvestment to capital returns.

ROIC has declined from 12.6% to 8.0% over nine years despite revenue nearly doubling — every dollar of new revenue produced only 17 cents of incremental net income, raising the uncomfortable possibility that Equifax has structurally settled at a lower-return profile than its pre-breach self. The $6.15B debt load at 3.4x EBITDA is manageable but not conservative, and the CFPB investigation with three separate Civil Investigative Demands targeting the TWN database threatens the very asset the bull case depends on. The 39% gap between GAAP EPS ($5.52) and adjusted EPS ($7.65) is among the widest in the S&P 500, and serial acquisition spending of $5.8B over a decade means the amortization driving that gap is not truly non-recurring.
