## What changed

Fortinet completed the business combination effective August 1, 2024 and subsequently reported $152.3 million cash purchase consideration in its financial statements. That is the buyer’s acquisition measure for Lacework Inc. The earlier $8.3 billion private financing valuation has a different date and basis; the two figures alone do not determine individual investor returns.
