Fermi Appoints TerraPower Veteran as New CEO, Stock Surges 23%

Fermi, the startup developing nuclear reactors to power artificial intelligence data centers, has named Lee McIntire as its chief executive. The appointment marks a critical moment for the company as it transitions from fundraising and strategic planning to construction and customer delivery.

McIntire joined Fermi as an independent board member and now moves into the top leadership role. His previous positions include chief executive roles at CH2M Hill, an engineering and construction firm, and TerraPower, the advanced nuclear startup founded by Bill Gates. He brings four decades of experience managing large-scale infrastructure projects, according to Marius Haas, Fermi’s chairman of the board.

The timing carries weight. Fermi’s stock jumped nearly 23% in trading following the CEO appointment, alongside news that the company had secured its first binding customer agreement. TensorWave, a provider of AI computing infrastructure, signed on as a customer for Fermi’s flagship facility, bolstering confidence in the venture’s ability to attract commercial interest.

The Leadership Reshuffling and Strategic Reset

The CEO hire represents Fermi’s second major personnel shift in recent months. More than three months prior to McIntire’s appointment, Fermi removed co-founder Toby Neugebauer from the chief executive post. Chief Financial Officer Miles Everson departed at the same time. The company framed these changes as part of its evolution into what it called “Fermi 2.0″—a recalibration of strategy and operations that included relocating corporate headquarters to Dallas.

Removing a co-founder from the CEO role signals fundamental strategic divergence or performance concerns. The fact that the CFO also departed suggested the shakeup extended beyond the executive suite into operational and financial planning. The details of the disputes remain private, but the outcome is clear: leadership focused on fundraising and growth was replaced by leadership focused on execution.

Haas described the new direction in practical terms. “Fermi’s next chapter is a construction and power delivery story,” Haas said in a statement announcing McIntire’s hiring. The company now prioritizes shepherding complex projects to completion over capital-raising or strategic vision-setting.

McIntire’s Distinctive Background

McIntire’s tenure at TerraPower places him within the advanced reactor ecosystem. TerraPower, backed by Gates and institutional investors, has pursued a design philosophy centered on reducing costs and improving safety relative to conventional nuclear plants. The company operates a prototype facility but has not yet achieved commercial-scale operation. McIntire’s direct familiarity with this technology, combined with his construction and project management expertise from CH2M Hill, positions him to bridge the gap between reactor design and actual deployment.

Haas emphasized that McIntire’s track record in delivering projects “on schedule, on budget, and safely” made him suited for the role. Building a nuclear facility and powering a data center campus requires coordinating with regulators, managing construction timelines, ensuring safety compliance, and maintaining budget discipline—all areas where McIntire has demonstrated capability.

Fermi’s Mission and Backing

Fermi America was co-founded with backing from Rick Perry, who served as U.S. Energy Secretary under the Trump administration. The company’s core mission centers on pairing nuclear power with artificial intelligence infrastructure—addressing the enormous and growing electricity demands of AI computation.

The venture’s focus reflects a genuine industry need. AI sector power consumption has become a constraint on growth. Major cloud providers report that power availability, not capital or engineering talent, now limits their ability to expand computing capacity. Fermi’s strategy of building dedicated nuclear-powered campuses for AI workloads represents one possible solution to this bottleneck.

Project Matador: The Nuclear-Powered AI Campus

Fermi is developing Project Matador, an AI campus located in Amarillo, Texas. This facility represents the tangible expression of Fermi’s strategy: constructing a data center campus powered entirely by nuclear reactors rather than traditional grid electricity or fossil fuels. The project reflects broader industry interest in nuclear energy as a solution to AI’s insatiable appetite for reliable, large-scale power supply.

Texas proved an attractive location. The state has one of the largest nuclear industries in the United States, with multiple operating reactors providing a foundation of expertise and infrastructure. The state’s deregulated electricity market creates incentives for new power generation capacity, and regulators bring experience managing large power consumers.

The First Binding Customer

TensorWave’s binding customer lease for Project Matador validates the model at an early stage. Rather than speculating about future demand, Fermi now has a committed customer with contractual obligations. This arrangement reduces the risk that the company builds expensive infrastructure without tenants ready to use it—a primary challenge facing other nuclear power startups attempting to serve the data center market.

The company announced the TensorWave deal on Monday, with the CEO appointment disclosed two days later on Wednesday. The proximity of these announcements suggests coordination—Fermi may have timed the CEO hire to coincide with customer news, creating a narrative of momentum and market validation.

Navigating the Nuclear-AI Infrastructure Landscape

Fermi enters a sector that is newly crowded. Multiple companies, including established nuclear operators and venture-backed startups, are pursuing similar strategies. Some focus on small modular reactors, others on conventional reactors repurposed for data center use. Fermi’s focus on a complete campus—reactor plus data center facilities—represents a distinct bet that integrated projects offer advantages over simply selling power into a grid.

The nuclear industry’s historical struggles with cost overruns and construction delays remain relevant context. Nuclear projects have repeatedly exceeded budgets and timelines, and regulators and neighbors scrutinize new nuclear builds intensely. These realities informed Haas’s emphasis on McIntire’s ability to deliver projects on schedule, on budget, and safely.

Execution as the Central Challenge

The stock market’s positive reaction to the CEO appointment and customer deal reflects investor appetite for solutions to AI power constraints. McIntire’s appointment signals Fermi’s intention to translate conceptual advantages into operational reality.

The company faces several concurrent tasks over the coming months and years. It must begin construction on Project Matador while securing additional customer commitments beyond TensorWave. It must navigate the regulatory approval processes required for new nuclear facilities in Texas. It must manage the integration of its Dallas headquarters while executing operations across multiple sites.

The appointment of an executive with McIntire’s background suggests Fermi’s board believes the venture has moved past early-stage capital-raising. The focus has shifted to whether the company can actually build and operate the infrastructure it has promised. The next challenge lies not in securing funding or signing customers, but in delivering power on time, within budget, and in compliance with nuclear safety standards. For a startup in this space, execution will determine whether Fermi becomes a category leader or another casualty of the gap between vision and reality.
