Worked example — The Shell Game

Unmasking "Acquisition Corp EU 4"

When "Acquisition Corp EU 4" won a massive €2B fiber-optic rollout contract in Spain, basic scrapers couldn't map the revenue to a ticker. Our Entity Resolution Engine immediately identified the SPV's ultimate parent via shared directorships and regional tax IDs, attributing the massive revenue beat to a prominent publicly traded telecommunications giant weeks before earnings.
