TransUnion launches First Look for mortgage lenders to cut origination costs by reviewing credit insights before purchasing scores

TransUnion has launched First Look Functionality for Mortgage, allowing lenders to review credit insights before purchasing scores. The tool enables mortgage lenders to buy credit reports alone or with their chosen score, then request additional scores only when needed, without incurring the cost of a second report when eligibility conditions are met. The innovation follows TransUnion's extension of 99-cent VantageScore 4.0 mortgage pricing through 2028, with no charge when pulled alongside a FICO Score. Traditional mortgage workflows often require lenders to purchase credit scores early, leading to unnecessary fallout costs. The functionality works with both soft-pull and hard-pull workflows and is compatible with government-sponsored enterprises and Federal Housing Administration automated underwriting systems. It's available through mortgage resellers without requiring changes to existing selling guidelines or policies.

TransUnion praised for growth, ScanSource struggles with declining sales

TransUnion and ScanSource represent contrasting fortunes in the business services sector, which has lagged the S&P 500 with an 8% gain versus 10.8% over six months. TransUnion, one of America's three major credit bureaus, shows strong momentum with 11.6% annual revenue growth over five years and projected 11.4% growth ahead. The company's 10.1% free cash flow margin provides resources for reinvestment. At $79.84 per share, it trades at 16.4x forward P/E. ScanSource presents challenges. The technology distributor's sales fell 4.9% annually over two years, with Wall Street forecasting modest 2.4% growth. Its poor 3.4% free cash flow margin limits investment flexibility. The sector faces pressure from AI disruption and tightening corporate budgets, though quality businesses can still deliver earnings growth. TransUnion trades at $15.4 billion market capitalisation, whilst ScanSource stands at $1.11 billion.
