Private ESOP Companies Outperform S&P 500 in 2026 Stout Index

The report underscores the long-term stability of the ESOP model, particularly among mature organizations. Companies maintaining plans for over two decades posted an 18.3% five-year annualized return, signaling that these structures remain resilient through varying economic cycles. The data suggests that maturity does not diminish performance, as plans established between five and 10 years showed similar strength at 18.7%.

Sector performance varied significantly, with the architecture, engineering, and construction industry leading the pack. These firms achieved a 23.1% five-year annualized return, narrowly edging out the industrials sector, which reported a 22.6% return. Aziz El-Tahch, President of ESOP Advisory at Stout, noted that the expanded sector-specific data provides stakeholders with a clearer lens to evaluate performance across different corporate lifecycles and debt repayment phases.
