What happens when the leader responsible for an organization’s success is suddenly unable to lead? For Nvidia, one of the world’s most valuable companies, the executive succession planning question has become an urgent reality.

On November 12, 2026, Nvidia announced that Jensen Huang, its co-founder and CEO of 33 years, had resigned effective immediately amid intense scrutiny over reports of extramarital affairs. The company’s board appointed Chief Financial Officer Colette Kress as interim CEO while it searches for a permanent successor.

Huang was instrumental in transforming Nvidia into a global leader in artificial intelligence. His technical expertise, strategic vision, and ability to anticipate and capitalize on emerging market opportunities helped drive the company’s extraordinary growth. But his departure has also exposed the risks associated with concentrating so much organizational responsibility in a single leader.

According to recent reporting, Nvidia had not publicly identified a successor to Huang before his resignation. Its unusual organizational structure, with dozens of executives reporting directly to the CEO, further complicates the transition. Although the board moved quickly to appoint an experienced interim leader, finding a permanent successor capable of assuming Huang’s extensive responsibilities presents a considerable challenge.

The situation raises a question that organizations across industries should be asking:

When an organization depends heavily on one leader, what happens if that leader is no longer available?

The Hidden Risk of Indispensable Leaders

Every organization has leaders who seem irreplaceable. They may be founders who built the business from the ground up, executives who maintain essential client relationships, or senior leaders whose expertise is critical to daily operations.

These individuals are often among an organization’s greatest assets. Their experience, judgment, and institutional knowledge are difficult to replicate. But when too much responsibility, knowledge, or decision-making authority rests with one person, that strength can also become a vulnerability. Consider what might happen if a critical leader departed unexpectedly:

• Important strategic initiatives could lose direction or momentum.
• Employees could face uncertainty about responsibilities and decision-making authority.
• Essential institutional knowledge could be lost.
• Client relationships and stakeholder confidence could be disrupted.
• The organization could be forced to make a rushed leadership appointment without sufficient information about potential successors.
• Investor confidence could weaken, potentially triggering a decline in the company’s stock price.

The financial implications of leadership uncertainty can be significant. Reuters reported a decline exceeding 12% during trading following Huang’s resignation. The market reaction illustrates how uncertainty surrounding a critical leader can affect confidence in an organization’s long-term prospects.

These risks aren’t limited to trillion-dollar corporations. In fact, smaller organizations may be particularly vulnerable when they have fewer qualified leaders available to step into critical roles. Organizations need to recognize where they are most vulnerable and take steps to reduce their dependence on individual leaders.

Why Waiting Until a Leader Leaves Is Too Late

One of the most common misconceptions about succession planning is that it becomes necessary only when a senior leader approaches retirement or announces an intention to leave. Unexpected departures, such as Huang’s, along with organizational restructuring and changing business priorities, can create an immediate need for capable leadership. By the time a vacancy occurs, it may be too late to identify, assess, and develop a suitable successor.

Effective succession planning helps organizations anticipate leadership transitions, develop qualified successors, and maintain continuity when circumstances change. It requires looking beyond individual replacements and asking a broader question:

Do we have the leadership capabilities needed to sustain our organization’s success, both today and in the future?

Three Questions Every Organization Should Be Able to Answer

Nvidia’s leadership transition offers an opportunity for leaders and boards to examine their own succession readiness. Here are three questions worth considering:

1. Which leadership roles are most critical to our success?

Not every leadership position carries the same level of organizational risk. Some roles are essential because of their strategic influence. Others depend on specialized expertise, important relationships, or responsibilities that would be difficult to redistribute. Identifying these critical roles is the foundation of effective succession planning.

2. Do we know who could step into those roles?

Having talented employees is not the same as having succession-ready leaders. Organizations need an objective understanding of their internal leadership bench, including employees’ strengths, development needs, and readiness for greater responsibility. This requires more than informal recommendations or assumptions about who might be next in line. SIGMA’s At-a-Glance Succession Bench worksheet provides a practical starting point for evaluating the strength of a leadership pipeline.

Structured leadership assessments, such as SIGMA’s Leadership Skills Profile – Revised® (LSP-R®), can help organizations make more informed decisions about potential successors and identify the capabilities they need to develop.

3. Are we actively preparing future leaders?

Organizations need to provide targeted development opportunities that prepare emerging leaders for the responsibilities of critical roles. These opportunities could include coaching, stretch assignments, mentoring. and leadership development programs aligned with future organizational needs.

Without deliberate development, even promising succession candidates may remain unprepared when an opportunity arises.

Why Leadership Character Matters in Succession Planning

The circumstances surrounding Huang’s departure also raise important questions about the role of character in executive leadership. When an organization becomes closely associated with a single individual, that leader’s personal conduct can have significant implications for its reputation, stability, and stakeholder confidence.

This makes leadership character an important consideration when evaluating potential successors. Qualities such as integrity, accountability, humility, and sound judgment influence how executives exercise authority, navigate difficult decisions, and earn the trust of employees and stakeholders. For organizations, the consequences of leadership misconduct can extend well beyond the individuals involved, potentially affecting employee confidence, organizational reputation, and business performance.

To help organizations evaluate and develop these qualities, SIGMA partnered with researchers at the Ivey Business School to develop the Leadership Character Insight Assessment (LCIA). The assessment measures 11 dimensions of leadership character and provides practical insights to support leadership development.

Incorporating character assessments into succession planning can help organizations gain a more complete understanding of potential successors and identify development needs before they assume greater responsibility.

Executive Succession Planning Doesn’t Have to Be Complicated

Many organizations recognize the importance of succession planning but struggle to determine where to begin. Developing a comprehensive succession plan can seem overwhelming, especially when competing business priorities demand immediate attention.

A practical starting point is to identify the roles that matter most, establish what successful leadership looks like in those positions and evaluate the strength of the internal talent pipeline. From there, organizations can prioritize development activities, address readiness gaps and establish a process for monitoring progress.

This approach gives organizations the flexibility to manage leadership transitions more effectively, whether anticipated or unexpected.

Don’t Wait for a Leadership Crisis to Start Planning

Nvidia’s unexpected leadership transition demonstrates how quickly an organization can face uncertainty when a critical leader departs. Although the company has appointed an interim CEO, identifying a permanent successor capable of sustaining its success presents a considerable challenge. For organizations of all sizes, the situation reinforces the importance of developing leadership capabilities and preparing for transitions well before they occur. Whether an organization has 50 employees or 50,000, the fundamental question remains the same:

If one of your most important leaders left tomorrow, would you be ready?

If the answer is uncertain, now is the time to start planning.
