Activist Movements Are Reaching SMEs
In April 2025, it was revealed that Aya Nomura, eldest daughter of prominent investor Yoshiaki Murakami, holds a 2.16% stake in major electronics retailer Yamada Holdings (source: Tokyo Press Report). Murakami, once known for leading the “Murakami Fund” and aggressively proposing shareholder actions against Japanese companies, now sees his daughter potentially engaging as an activist investor with Yamada HD.
Activist investors—so-called “vocal shareholders”—have traditionally targeted large corporations. However, in recent years, smaller companies with lower market capitalizations and weaker governance have become increasingly attractive targets. Why? Because management changes are easier to effect in SMEs, and shareholder proposals are more likely to pass.
Some business owners may think, “We’re unlisted, so this doesn’t apply to us.” But activist tactics are diversifying. Even for unlisted companies, cases are rising where minority shareholders file lawsuits or demand higher prices during MBOs (management buyouts), exploiting governance gaps.
This article provides practical governance measures that SME leaders should take immediately in light of this news. It’s also important to view activists not as “enemies” but as “catalysts” for enhancing corporate value.
Why SMEs Are Now Targets
Low Market Capitalization and Fewer Shares Outstanding
For activists, SMEs are “easy acquisition” targets. With a small market cap, a modest investment can secure significant voting rights. Additionally, fewer shares outstanding mean even a minority shareholder can influence management.
For example, in a company with 1 million shares outstanding, acquiring 2% requires just 20,000 shares. In contrast, a large corporation might require hundreds of millions of shares, posing a much higher financial hurdle.
Governance “Gaps” Are Easily Exposed
Many SMEs are dominated by owner-managers with absolute power, often rendering boards of directors mere formalities. Even if outside directors exist, they may only approve management-friendly decisions, failing to provide genuine oversight.
Activists keenly identify these governance gaps. Common issues include:
- Homogeneous board composition (only internal directors, or outside directors too close to management)
- Late shareholder meeting notices or insufficient disclosure
- Excessive retained earnings with inadequate shareholder returns
- Unresolved succession plans with no clear path for business continuity
These problems are more prevalent in SMEs than large firms. For activists, they represent prime opportunities.
Three Impacts of Activists on SMEs
1. Forced Transparency
Activists first demand information disclosure. Business plans, financials, governance structures—previously confidential data—must be revealed. While stressful for management, this can ultimately boost corporate value.
Why? Because disclosure forces management to confront their company’s challenges head-on. Strategies previously guided by intuition or emotional decisions are re-evaluated based on objective data.
2. Pressure to Prioritize Short-Term Gains
Most activists aim for quick profits after acquiring shares. They aggressively demand increased dividends or share buybacks to boost shareholder returns.
This creates a dilemma for SME leaders: prioritizing short-term stock price measures over long-term investments (R&D, capital expenditure, talent development). Whether this constitutes “good governance” is debatable.
3. Higher Risk of Management Turnover
Activists’ most powerful weapon is the removal of directors at shareholder meetings. If their proposals pass, current management may be forced out.
Companies where founding families hold less than a majority, or with dispersed shareholding structures, are particularly vulnerable. While management changes may cause short-term disruption, they can also bring fresh perspectives long-term.
Three Actions SME Leaders Should Take Now
1. Design “Offensive Governance,” Not Just Defensive Measures
Many leaders rush to implement “takeover defenses” against activists. But this isn’t a real solution. Governance designed solely for defense can reduce management flexibility and harm corporate value.
The key is “offensive governance.” Consider these approaches:
- Appoint outside directors who are “business connoisseurs”—not just monitors, but partners for growth
- Shift board agendas from “risk management” to “growth strategy discussions”
- Institutionalize regular dialogue with shareholders to address concerns proactively
By doing so, activists may conclude, “This company has solid governance,” reducing the likelihood of attack. Even if activists appear, management’s arguments become more persuasive, gaining support from other shareholders.
2. “Visualize” Your Shareholder Structure and Monitor Regularly
Early detection of activist moves requires regular checks of the shareholder register. Watch for these changes:
- Major shareholder shifts (anyone acquiring 5% or more of shares)
- Changes in shareholder type (e.g., from individual to institutional investors)
- Sudden stock price fluctuations (possible activist accumulation)
This information is available from securities firms or shareholder register administrators. Make it a habit to check monthly. If suspicious activity arises, consult a lawyer or consultant immediately.
3. Understand “Minority Shareholder Rights” and Prepare in Advance
Activists fully leverage their shareholder rights. Key rights SME leaders should know include:
- Shareholder proposal rights (exercisable by holders of 1% or more voting rights, or 300+ shares held for 6+ months, up to 8 weeks before the general meeting)
- Inspection rights (holders of 3%+ voting rights can inspect company books)
- Director removal rights (directors can be removed by shareholder resolution)
Understanding these rights and preparing responses is crucial. For example, establish a process to review meeting agendas in advance if a shareholder proposal is expected. If inspection rights are exercised, clearly separate disclosable information from confidential data. Such preparation strengthens your position in negotiations with activists.
Conclusion: Activists as a “Wake-Up Call” and “Opportunity”
The news of Murakami’s daughter acquiring Yamada HD shares is a wake-up call that SMEs cannot ignore. Activists are no longer just a concern for large corporations.
But viewing them solely as “enemies” is premature. The issues they raise often highlight “governance blind spots” that management has overlooked. By taking their demands seriously and using them as a catalyst for improvement, you can ultimately enhance corporate value.
When a “vocal shareholder” appears, how will your company respond? The answer depends on the quality of your everyday governance. Now is the time to review your governance and prepare with an offensive mindset.
