- Oklo has acquired ARMEC, a precision manufacturer based in Tennessee, as the company looks to bring more of its reactor and fuel-manufacturing operations under its own roof.
- The deal arrives while investors are weighing if Oklo’s nuclear-power pitch is enough for a $10 billion market cap even though it doesn’t have power revenue yet.
- Southern Company and other big utilities are already making money from the surge in power demand coming from new data centers.
Oklo shares moved higher Monday. The advanced nuclear company said it bought ARMEC, a precision engineering and manufacturing business in Oak Ridge, Tennessee. Oklo said the deal, which closed June 4, boosts its internal capacity for advanced reactor and fuel-manufacturing work. The company called the acquisition another operating milestone for a stock that’s still trading mostly on future data center power needs.
Timing is key as investors watch two separate nuclear names. There are pre-revenue bets like Oklo, driven by licensing, fuel, and build-out updates. Then there are regulated utilities like Southern Company that already sell power to big users such as data centers. Oklo was last at $59.86 in late-morning New York action, up 3.0%, putting its market cap around $10.2 billion.
Oklo says it is adding about 40 engineers and skilled workers with the ARMEC acquisition, along with over 20 years of experience in nuclear and industrial manufacturing. Oklo also said ARMEC was free cash flow positive last fiscal year. The company did not say how much it paid.
Oklo CEO Jacob DeWitte said in a statement that “Advanced nuclear deployment requires manufacturing depth.” ARMEC President Travis Reagan said the deal lets his team help Oklo build “the manufacturing foundation needed to support advanced nuclear deployment.” Oklo
Oklo now has a firmer answer for investors questioning its valuation against its lack of commercial revenue. A June 6 article from 24/7 Wall St. pointed to Southern Company as a safer bet on data-center electricity demand, citing Oklo’s non-binding pipeline and the company’s first-power goal still set for late-2027 to early-2028.
Oklo is drawing attention to execution after its filings showed zero revenue for the first quarter, a net loss of $33.1 million and $51.2 million in operating expenses. Cash, cash equivalents and marketable debt securities totaled about $2.54 billion at the end of March.
Oklo is working on the Aurora powerhouse, a fast reactor using liquid metal cooling and metal fuel. The Nuclear Regulatory Commission said it’s in pre-application talks with Oklo and lists the Aurora reactors at a maximum output of 75 megawatts electric.
Yahoo Finance picked up a Motley Fool piece flagging July as a key month. That’s when Atomic Alchemy, tied to Oklo, is aiming for criticality—sustained nuclear reaction—at its Groves Isotopes Test Reactor in Texas. The Energy Department’s Reactor Pilot Program wants at least three advanced reactor concepts, not at national labs, to hit criticality by July 4, 2026.
The next few weeks could be key for sentiment. A test reactor milestone alone won’t bring commercial power revenue yet. The Motley Fool said on June 4 that Oklo still needs NRC approval and access to high-assay low-enriched uranium, or HALEU, before it can roll out reactors widely.
Southern Company is on the opposite end of the trade. The utility posted first-quarter adjusted earnings of $1.32 per share, up from $1.23 last year. Operating revenue came in at $8.4 billion for the quarter, up 8%. CEO Chris Womack said Southern is putting money into growth but keeping a close eye on reliability and steady rates.
Southern stock slipped roughly 1% to $91.67 Monday, putting its market cap near $103.4 billion. NuScale Power, which competes with Oklo in the small modular reactor space, gained 3.4% to $10.86.
Analysts are still watching Oklo. HC Wainwright’s Sameer Joshi said Oklo is “in the development stage,” but said the key event is criticality at Atomic Alchemy’s Groves reactor by July 4. Needham’s Sean Milligan noted Oklo’s balance sheet now removes “near-term funding risk,” Benzinga reported. Sahm
Manufacturing depth isn’t the full answer. Oklo points out there isn’t enough HALEU or plutonium-based fuel on the market. The company also cautions that customers can pull out of non-binding deals, and that slow regulatory approvals could push back both construction and operations.
Oklo has the ARMEC deal as a real asset now, instead of only a reactor design and a theory about demand. But the next test for the market comes soon—if Oklo can use July’s milestones, any regulatory wins and a tighter supply chain to make power sales look realistic.
