What does it tell you when the CEO and CFO of a company both walk out the door within days of each other? Not a quiet restructuring. Not a planned transition. A simultaneous exit from the two people most responsible for keeping the lights on — which, given Fermi’s entire pitch, is a deeply ironic way to put it.
Fermi Inc. is one of those startups that sounds almost too ambitious to be real. The company, co-founded by former U.S. Energy Secretary Rick Perry, has been positioning itself at the intersection of two of the hottest narratives in tech right now: artificial intelligence and nuclear power. The idea is straightforward enough — AI data centers are energy-hungry beasts, and nuclear is one of the few power sources that can realistically feed them at scale. Fermi wanted to build that future, anchored by an AI campus in Texas.
On paper, that’s a compelling story. In practice, April 2026 told a different one.
What Actually Happened
Co-founder and CEO Toby Neugebauer departed effective April 17, 2026. CFO Miles Everson followed. Shares dropped 22% on the news, with some reports tracking the decline as steep as 17.56% in a single session. Neugebauer isn’t gone entirely — he stays on as chairman of the board — but the operational leadership of the company has been gutted in one swift move.
That distinction matters. Staying on as chairman is the corporate equivalent of saying “I believe in the mission” while quietly handing someone else the keys. It’s a face-saving move, and there’s nothing wrong with that, but investors aren’t paid to read between the lines charitably. They saw two top executives leave and they sold.
The Texas Campus Problem
Fermi has faced what the company’s own coverage describes as “headwinds” with its AI campus in Texas. That’s a polite word for serious obstacles. Building nuclear-adjacent infrastructure in the United States is not a fast process. Regulatory timelines are long, capital requirements are enormous, and the gap between a compelling pitch deck and actual megawatts flowing into a data center is measured in years, not quarters.
For a startup operating in that space, the pressure on leadership is relentless. You’re constantly managing investor expectations against a reality that moves slowly by design. When the CEO and CFO both exit in the same window, the most honest read is that the gap between the story being told and the progress being made became too wide to manage.
Why This Matters Beyond Fermi
I review AI tools and agents for a living. Most of what lands on my desk is software — models, wrappers, agents, APIs. Fermi is a different kind of bet. It’s a hardware and infrastructure play dressed up in AI language, and that distinction is important when you’re trying to assess what went wrong here.
The AI industry has a tendency to treat energy infrastructure like a solved problem, or at least someone else’s problem. It isn’t. The demand that large language models and AI training clusters place on power grids is real and growing, and the companies trying to build solutions for that demand are operating in a genuinely difficult space. Nuclear is not plug-and-play. It requires political will, regulatory patience, and capital that doesn’t panic at the first sign of turbulence.
Fermi’s leadership departures suggest the company may be learning that lesson the hard way. A 22% share drop is the market saying it has lost confidence in the execution, not necessarily the idea.
What Comes Next
Fermi will need to move quickly to install credible operational leadership and give investors a clear picture of where the Texas campus actually stands. Vague reassurances won’t hold. The company’s credibility is now tied directly to its ability to show tangible progress — permits, partnerships, timelines with real dates attached.
Rick Perry’s name and Neugebauer’s continued presence on the board provide some institutional continuity, but boards don’t build power plants. Operators do.
The nuclear-plus-AI thesis isn’t dead. If anything, the underlying demand that Fermi is trying to address keeps growing. But a startup in a capital-intensive, regulation-heavy sector cannot afford to look like it’s losing its footing at the leadership level. Right now, Fermi looks exactly like that.
Whether the new leadership can steady the ship before investor patience runs out is the only question worth watching.
