B2B SaaS Valuation Shift: Growth and Category Leadership Eclipsing Rule of 40
Kroll's Summer 2026 Global Software Sector Update, analyzing public comps and software M&A data through mid-2026, highlights a fundamental restructuring of B2B SaaS valuation frameworks. Traditionally, the Rule of 40 served as the gold standard for balancing growth and profitability. However, the latest market data indicates that profitability margins exceeding 25% no longer command valuation premiums. Instead, the market is rewarding pure revenue growth and undisputed category leadership. Investors are paying significant premiums for companies that command their respective market niches, rendering traditional balanced efficiency metrics secondary. This pivot suggests that enterprise buyers and private equity firms are willing to underwrite aggressive expansion strategies, betting heavily on winners taking all in a rapidly consolidating SaaS ecosystem.

Kroll’s Summer 2026 Global Software Sector Update reveals that the traditional Rule of 40 metric is losing its relevance in B2B software valuations. The market is increasingly prioritizing top-line growth and category dominance over high operating margins when pricing software M&A and public comps.
