The key uranium mining and fuel companies — and how UK investors can access them

The Uranium Equity Landscape

The universe of listed uranium companies is surprisingly small. Unlike gold or oil, where hundreds of producers compete, uranium production is dominated by a handful of companies. This concentration means that when uranium prices rise, there are relatively few equities for investors to buy — which can amplify share price movements.

Below are six of the most significant uranium stocks for UK investors, covering established producers, growth developers, and a uranium holding company listed in London.

1. Cameco Corporation (CCO on TSX; CCJ on NYSE)

Cameco is the largest publicly traded uranium company in the world. Based in Saskatchewan, Canada, it operates the McArthur River mine (the world's largest high-grade uranium mine), the Key Lake mill, and has stakes in Cigar Lake and the Inkai joint venture in Kazakhstan. Cameco also operates conversion facilities in Canada and holds a 49% stake in Westinghouse (one of the world's leading nuclear services and fuel fabrication companies) alongside Brookfield.

Cameco is a diversified play across the fuel cycle — not just mining, but conversion and fabrication too. It is widely held by institutional investors and is a top holding in most uranium ETFs.

UK access: Available via most UK brokers (Hargreaves Lansdown, Trading 212, Interactive Investor, AJ Bell) as a US-listed ADR (NYSE: CCJ) or Canadian listing (TSX: CCO). Eligible for a Stocks & Shares ISA.

2. Kazatomprom (KAP on LSE, KZAP on AIX)

Kazatomprom is the world's largest uranium producer, accounting for roughly 22% of global supply. It is majority-owned by the Kazakh sovereign wealth fund (Samruk-Kazyna) and listed in London, Astana and Almaty. The company operates primarily via in-situ recovery (ISR) — the lowest-cost uranium mining method.

Kazakhstan's uranium is cheap to produce (all-in sustaining costs around $20–25/lb), but the country carries geopolitical risk. In 2021–2022, Kazatomprom reduced production due to supply chain issues (sulphuric acid shortages and COVID-related disruptions). Investors should monitor Kazakh politics and the company's relationship with Russia for logistics.

UK access: Listed on the London Stock Exchange as GDRs (LSE: KAP). Available through major UK brokers. ISA eligibility may vary — check with your broker.

3. Paladin Energy (PDN on ASX; PALAF on OTC)

Paladin Energy is an Australian-listed uranium producer that operates the Langer Heinrich mine in Namibia. The mine was placed on care and maintenance in 2018 during the uranium price downturn but was restarted in 2024 as prices recovered. Paladin also acquired Fission Uranium in 2024, giving it exposure to the Patterson Lake South project in the Athabasca Basin.

Paladin is a leveraged play on the uranium price — as a restart producer with ramp-up risk, its shares can be volatile. It is best suited to investors comfortable with higher risk.

UK access: Available via OTC markets (PALAF) or through brokers offering ASX access. Less commonly available in ISAs — check with your broker.

4. NexGen Energy (NXE on NYSE; NXG on TSX)

NexGen Energy is a Canadian development-stage company focused on the Arrow deposit in the Athabasca Basin — potentially the largest and highest-grade uranium development project in the world. The Rook I project is progressing through permitting and feasibility, with first production targeted for the late 2020s.

NexGen is a pure development play — it has no current production. Its valuation is based on the expected future cash flows from Rook I. The stock can be volatile, moving with uranium prices, permitting news, and construction milestones.

UK access: Available on NYSE (NXE) via most UK brokers. ISA-eligible.

5. Denison Mines (DNN on NYSE/TSX)

Denison Mines is developing the Wheeler River project in the Athabasca Basin, which includes the high-grade Phoenix and Gryphon deposits. Denison is using the In-Situ Recovery (ISR) method for Phoenix — which would be the first ISR operation in the Athabasca Basin. The company also holds a 22.5% stake in the McClean Lake mill and has a portfolio of exploration assets.

Denison is another development-stage play, though it has some existing assets that provide optionality. Its feasibility study for Phoenix was completed in 2023, and the project is moving toward a construction decision.

UK access: Available on NYSE (DNN) via most UK brokers. ISA-eligible.

6. Yellow Cake plc (YCA on LSE AIM)

Yellow Cake plc is a London-listed company that holds physical uranium (U₃O₈) — similar in concept to the Sprott Physical Uranium Trust, but structured as a UK AIM-listed company. It buys uranium from Kazatomprom under a long-term supply agreement and stores it at licensed facilities in Canada and France.

Yellow Cake gives investors direct exposure to the uranium spot price without mining or operational risk. Its NAV moves with the uranium price, though the share price can trade at a premium or discount to NAV.

UK access: Listed on AIM (LSE: YCA). Available through all major UK brokers. ISA-eligible.

How to Choose

For lower risk, Cameco and Kazatomprom are established producers with diversified assets. For growth, NexGen and Denison offer development-stage upside. For direct uranium price exposure without operational risk, Yellow Cake plc or the Sprott Physical Uranium Trust are the most straightforward.

Many investors combine several — a producer (Cameco), a developer (NexGen), and a physical holder (Yellow Cake) — to spread risk across the value chain.
