Missouri firms post record revenue growth as regional platforms scale nationally

Missouri's largest firms reported a striking 2025 growth year: Polsinelli passed $1.21 billion in gross revenue, up 25.5%; Shook, Hardy & Bacon rose 28.4% to $643.4 million; Spencer Fane rose 25.5% to $404 million; and Lathrop GPM rose 31.3% to $263.3 million. Several firms linked growth to lateral hiring, geographic expansion, technology investment and larger national platforms. Regional-headquartered firms are no longer just local market stories. The economics increasingly resemble platform-building: grow through laterals and combinations, use lower-cost operating bases, invest in AI and client service infrastructure, and compete nationally while preserving regional margin advantages.
