Does employee stock ownership improve long-term company performance?

Do ESOPs boost performance right away, or is there a delay?

The evidence shows that the positive impact of employee stock ownership on company performance is not instant—it takes time to materialize. A study of 18 listed commercial banks in Vietnam from 2015 to 2019 found that ESOP issuance had a positive effect on financial ratios, but only after a lag of about two years [4]. This means companies and investors should not expect immediate returns; the benefits come as employees become more aligned with long-term company goals and as the ownership culture develops.

This delayed effect is consistent with the idea that ESOPs are a long-term incentive. The same study noted that the higher the ESOP issuance ratio relative to the bank's size, the stronger the positive influence on performance [4]. So, a well-designed, substantial ESOP can eventually improve profitability, but patience is required.

Can ESOPs fix problems caused by large wage gaps?

The short answer is: not on their own. A 2026 study of 427 Korean firms examined whether employee participation systems—including ESOPs—could soften the negative effects of wage gaps on company performance. The researchers found that large wage gaps between different job levels (vertical gaps) hurt performance, and excessive pay differences among similar-rank employees (horizontal gaps) also became harmful beyond a certain point [1]. However, the study found that ESOPs did NOT have a statistically significant moderating effect on this relationship [1].

In contrast, labor unions did have a significant positive moderating effect, helping to mitigate the negative consequences of wage disparity [1]. This suggests that ESOPs are not a substitute for collective bargaining or fair pay structures. For an ESOP to contribute to long-term performance, it likely needs to be paired with other practices that ensure employees feel the overall compensation system is fair.

What else matters for ESOPs to work?

Employee stock ownership is not a magic bullet—it works best within a healthy corporate environment. A study of Chinese A-share firms found that weak corporate governance and institutional deficiencies (like poor listing and delisting processes) were linked to lower stock returns and net cash flows [2]. This implies that if a company has fundamental governance problems, simply giving employees stock may not improve performance.

Additionally, research on 17 U.S. publicly traded companies found that firms investing in an internal 'culture of health' (programs and policies supporting employee well-being) saw their stock price appreciate by 115% from 2013 to 2017, compared to 69% for the S&P 500 [3]. While this study did not directly test ESOPs, it highlights that employee-focused strategies can drive long-term value. Combining ESOPs with a genuine commitment to employee welfare and strong governance is likely more effective than any single initiative.
