Top 3 Australian Nuclear Stocks To Watch In September 2026

Energy price shocks are back in the headlines, with oil flows swinging as Saudi Arabia reopens its key East West pipeline after drone attacks and a temporary shutdown. When fossil fuel supply looks fragile, reliable low carbon power such as Australian nuclear related stocks tends to draw fresh attention. This article breaks down three stocks from our nuclear energy universe that could help investors understand that shift.

The three nuclear energy stocks covered below are just a starting sample, with the full screen surfacing 23 more companies with equally detailed stories that are not covered in this article. To go deeper into the wider opportunity set, identify patterns, and analyze potential high conviction ideas, head straight to the Nuclear Energy Stocks screener .

Worley (ASX:WOR)

Worley is a global engineering and project services group that helps design, build, run, and retire complex energy assets, including nuclear power facilities and fuel cycle infrastructure that link directly to this screener's theme of reliable low carbon electricity.

Worley generates A$6.2b of revenue from the Americas, A$4.5b from EMEA, A$1.3b from APAC and A$265m from procurement activities, with an unallocated associate adjustment of A$1.6b, and the group carries a market value of about A$4.8b.

For nuclear focused investors, Worley matters because it sits in the middle of the project pipeline that keeps reactors and related infrastructure designed, upgraded, and safely wound down over decades.

"The accelerating global push for decarbonisation and energy transition is expanding Worley's addressable market, as evidenced by 60% of FY25 revenue coming from sustainability-related work (up from 52% in FY24); further investment and government policies towards net zero are likely to boost revenue streams, especially in renewables, hydrogen, and carbon capture."

What really moves the dial from here depends on how one quiet pressure on future earnings quality and cash generation resolves over time.

If that earnings pressure is on your mind, read the full narrative for Worley to see how Worley's decarbonisation exposure and contract mix could reshape the risk reward profile.

Boss Energy (ASX:BOE)

Boss Energy is a uranium producer anchored by its 100% owned Honeymoon project in South Australia, which supplies uranium concentrate for nuclear fuel. The group generated A$151 million from Australian Uranium Operations and carries a market value of about A$716 million.

Boss Energy gives this screener direct exposure to uranium production, with Honeymoon tying the business closely to the fuel supply chain that keeps nuclear reactors running and low carbon baseload power on the grid.

"Record quarterly Honeymoon output of 456,000 pounds of uranium drummed, alongside guidance for 1.6 million pounds in FY26 production, indicates a larger volume base that could support higher revenue over time if this operational profile is maintained."

What happens to Boss Energy's earnings power from here depends on how one emerging cost and contract pressure affects margins through the cycle.

That cost pressure is exactly what full narrative for Boss Energy unpacks, showing how Boss Energy's production profile and contracts could be accelerating or masking the next phase of earnings power.

Paladin Energy (ASX:PDN)

Paladin Energy is a pure-play uranium group for this screener, with mining and development focused on supplying fuel for nuclear reactors rather than broader diversified commodities exposure.

Paladin Energy generates about US$304 million from its Langer Heinrich uranium mine in Namibia, with sales spread across Asia, Europe, and North America, and the stock carries a market value of roughly A$4.6b.

For investors following nuclear fuel supply rather than reactor construction, Paladin Energy offers a direct link to uranium volumes tied to long-life resources in Namibia and a growth option in Canada.

"Paladin already has 22.3 million pounds contracted out to 2030 across 12 offtake agreements, with recent sales realised at US$69.90/lb."

The real swing factor is how one future shift in its cost base and project timing shapes the durability of those uranium-linked cash flows.

That cost base question sits at the centre of Paladin Energy's story, and the full narrative for Paladin Energy shows whether those uranium contracts are accelerating returns or quietly masking them in the future.
