When A Company's Greatest Asset Becomes It's Greatest Risk

How Much Depends on One Person? A Guide to Key Person Risk for Investors

Friday, November 13, 2026

When evaluating an investment, it's easy to become focused on the numbers: revenue

growth, profit margins, competitive advantages, market share, and future earnings potential. But there's another important factor that investors sometimes overlook: How dependent is the business on one individual? This is known as key person risk, and it can have a significant impact on a company's financial performance, reputation, and ultimately, its stock price.

Recent headlines surrounding one of the world's most influential technology companies and its high-profile founder provide a timely reminder of just how quickly circumstances involving a company's most influential leader can become an investment consideration.

Key person risk refers to the potential negative impact on a business when an individual whose knowledge, leadership, relationships, reputation, or decision-making abilities are particularly important to the organization becomes unavailable or creates a disruption. This individual is often the founder, CEO, or another senior executive, but it can also be a lead salesperson, chief technology officer, or individual responsible for a critical business relationship. In some companies, the success of the entire organization is closely tied to one person's vision or experience.

While having a strong leader can be tremendously advantageous, it can also create a concentration of risk. If that individual leaves, becomes incapacitated, makes a significant business mistake, or becomes involved in a public controversy, the consequences can extend well beyond the individual. Consider the example mentioned earlier: A leading technology company has become one of the most influential businesses in the artificial intelligence industry. Much of its success has been associated with its high-profile co-founder and CEO, whose leadership has played a central role in shaping the company's strategy, culture, and position within the industry. Over time, this individual has become an important part of the company's identity. Recently, reports emerged concerning the executive's personal relationship with a businesswoman who has been accused of having ties to foreign intelligence. The executive acknowledged an extramarital relationship and apologized to his family and company employees. The situation has attracted investor attention, contributed to significant volatility in the company's shares.

A company's risks are not limited to its products, financial statements, or competitive position. The actions and circumstances of its leadership can also influence shareholder value.

Nevertheless, the situation highlights an important investment lesson: A company's risks are not limited to its products, financial statements, or competitive position. The actions and circumstances of its leadership can also influence shareholder value.

Even when a company has exceptional technology, strong financial performance, and a dominant market position, unexpected developments involving a key executive can introduce uncertainty.

The good news is that many companies recognize key person risk and work to mitigate it behind the scenes by creating depth in their management structure and focusing on healthy corporate governance. This includes establishing an independent board of directors, oversight procedures, and transparent reporting.

My favorite example of a company attempting to unconventionally mitigate key person risk comes from the famous Japanese video game company Nintendo. Many, if not most, of Nintendo's most valuable franchises (Mario, Donkey Kong, and The Legend of Zelda) were created by one visionary individual: Shigeru Miyamoto. In 2016, Nintendo reportedly deemed his preferred method of commuting to work, riding his bicycle, to be too dangerous and required that he drive to the office instead.

So, what can you do as an investor to help protect yourself against key person risk in your portfolio?

Perhaps the most practical way to manage this risk as an investor is through diversification. Even a well-researched company can experience unexpected setbacks. Holding investments across different companies, industries, and asset classes can help reduce the impact that a problem at any one company has on an overall portfolio. Diversification does not eliminate investment risk or guarantee against losses, but it can help prevent excessive exposure to a single company's circumstances.

It is important to understand how much of the company's success is attributable to one individual and whether that advantage could survive a leadership transition.

Aside from diversification, it can be helpful to understand how much of a company's value is tied to one person. Just because a company has an effective founder or CEO doesn't automatically make it a poor investment. In fact, exceptional leadership can be a major competitive advantage. However, it is important to understand how much of the company's success is attributable to one individual and whether that advantage could survive a leadership transition.
