Nuclear Startup Last Energy Secures $100 Million To Revolutionize Modular Reactor Technology

After years of perseverance in a challenging market, nuclear startups are now emerging as pivotal players in the energy sector. Last Energy, a frontrunner in compact nuclear power, recently closed a $100 million Series C funding round led by the Astera Institute. With significant backing from venture firms including AE Ventures, Galaxy Fund, Gigafund, JAM Fund, The Haskell Company, Ultranative, and Woori Technology, Last Energy is poised to redefine the economics of nuclear energy.

From Skepticism to Mainstream Acceptance

Bret Kugelmass, Founder and CEO of Last Energy, reflected on the evolving perception of nuclear power. “For the first half a decade that I was advancing nuclear as a solution, I had to explain why it was important,” he explained. “Now, the industry and investors understand that nuclear is a key part of our future.” This shift in sentiment marks a significant turning point, with broader market acceptance fueling innovation and investment.

Innovative Reactor Design Rooted In History

Last Energy is reimagining nuclear generation with its small modular reactors, capable of producing 20 megawatts—enough to supply power for roughly 15,000 homes. What distinguishes the company is its adaptation of a reactor design developed decades ago for the NS Savannah, the world’s first nuclear-powered merchant ship. By scaling up a design originally intended for a vessel, Last Energy aims to achieve both cost reduction through mass manufacturing and heightened efficiency.

Pilot Project And Roadmap To Commercial Production

The company is initially deploying a 5-megawatt pilot reactor at a facility leased from Texas A&M University. This pilot project, fully financed by the latest funding round, will pave the way for its first commercial products. The pilot is slated to begin operations next year, with a full-scale 20-megawatt reactor expected to enter production by 2028.

Permanent Reactor Encapsulation And Waste Management

In a groundbreaking approach to reactor design and waste management, Last Energy permanently encases each reactor core in 1,000 tons of steel—a process estimated to cost around $1 million per unit. According to Kugelmass, while many assume that conventional materials such as concrete would be cheaper, nuclear-grade concrete significantly raises costs. The reactors are delivered with six years’ worth of uranium fuel, and the design ensures that the steel chamber, once the reactor’s operational life is exceeded, serves as an integrated waste cask, thereby streamlining disposal concerns.

Driving Down Costs Through Manufacturing Advances

While the nuclear industry faces inherent fixed costs due to stringent regulatory requirements, Last Energy is confident that mass production and innovative engineering will lead to substantial cost reductions. Drawing parallels with other industries that have seen prices halve with every tenfold increase in production, Kugelmass envisions a future where nuclear energy scales dramatically—transforming the cost dynamics across the sector.

With robust investment and a clear strategic roadmap, Last Energy is not only advancing nuclear technology but also positioning itself to meet the rising global demand for reliable, large-scale power generation.

Cyprus Holds Its Appeal For Investors Despite Energy And Financing Headwinds

Cyprus continues to stand out as one of Europe’s more resilient investment destinations. According to the latest EY Cyprus Attractiveness Survey 2026, 83 per cent of international investors still regard the island as attractive for foreign direct investment, even as concerns over energy costs, access to finance and bureaucracy persist.

Presented by Stelios Demetriou, EY Cyprus Head of Strategy and Transactions and M&A Leader for Central, Eastern and Southeastern Europe & Central Asia, the report estimates Cyprus’ FDI stock at roughly €82 billion in 2025. Investment remains concentrated in financial services, real estate and information and communications technology.

Investor Confidence Remains Broadly Intact

The survey shows a market that continues to command credibility among global capital allocators. Of the respondents, 56 per cent described Cyprus as definitely attractive and another 27 per cent as fairly attractive. A further 13 per cent were neutral, while only 4 per cent considered the island unattractive.

The findings are based on responses from 80 foreign investors across 23 countries and 11 sectors. Senior executives and investment decision-makers took part, and around 92 per cent of respondents already have business operations in Cyprus.

That established presence is translating into stronger intent. Sixty-seven per cent of respondents said they plan either to enter the Cypriot market or expand existing operations, up from 57 per cent in 2024 and just 29 per cent in 2022.

Among companies already operating on the island, 62 per cent expect to expand over the next 12 months, while 29 per cent intend to maintain current activity levels. Half of those without an existing footprint said they are considering entry into the market.

Tax Still Anchors The Investment Proposition

Tax remains Cyprus’ most powerful competitive advantage. Ninety per cent of respondents rated the country’s corporate tax regime and broader tax framework as attractive. Quality of life followed at 82 per cent, while political and social stability scored 65 per cent.

Investor confidence in the local workforce was also notable, with 58 per cent citing skills as a strength. Nearly half, 49 per cent, pointed to the country’s growth prospects.

The emphasis on taxation carries added significance after Cyprus raised its corporate income tax rate from 12.5 per cent to 15 per cent at the start of 2026 as part of wider tax reform. The European Commission has noted that corporate income tax still plays an unusually large role in Cyprus’ public finances, accounting for about 20 per cent of tax revenues, more than twice the EU average.

Energy, Finance And Red Tape Remain The Pressure Points

For all the optimism, investors were clear about where Cyprus must improve to sustain momentum.

Energy costs were the most frequently cited weakness, mentioned by 50 per cent of respondents. Access to finance and capital followed at 38 per cent, while the bureaucratic and administrative environment was flagged by 35 per cent. Transport and logistics infrastructure was cited by 33 per cent, and the availability of investment opportunities by 31 per cent.

These concerns extend beyond the EY survey. The European Commission has also identified access to finance and the business environment as areas requiring further reform, while calling for faster progress on renewables, electricity grids and storage to ease energy costs.

Energy has become an even more important issue in 2026. The Commission expects Cyprus inflation to rise to 3.6 per cent next year, largely because of higher energy prices linked to the Middle East conflict, even as it forecasts economic growth of 2.3 per cent this year and 2.7 per cent in 2027.

Geopolitics Is Rising On The Risk Agenda

Geopolitical uncertainty is now firmly in investors’ line of sight. Seventy-four per cent of respondents identified geopolitical tensions and conflicts as a potential threat to Cyprus’ attractiveness over the next three years.

That concern ranked well ahead of low connectivity, adverse reputation and a heavier regulatory burden, each cited by 29 per cent. Tight labour market conditions followed at 27 per cent, while volatile energy prices and supply problems were noted by 26 per cent.

Beyond The Core Economy, New Growth Areas Are Emerging

Despite the risks, investors are looking beyond Cyprus’ traditional strengths. While 48 per cent said future investment would focus on the sale of products and services, 21 per cent identified research and development, and 19 per cent pointed to business support services. Continued interest in regional headquartering also signals the island’s evolving role as a corporate base for wider markets.

Looking ahead, 60 per cent of respondents expect Cyprus to become more attractive for FDI over the next three years, including 9 per cent who anticipate a significant improvement. Another 24 per cent expect little change, while 6 per cent foresee deterioration.

Real estate, infrastructure and construction were seen as the sectors most likely to drive longer-term growth, cited by 23 per cent of investors. Tourism and leisure, as well as ICT and telecommunications, followed at 14 per cent each, with payments and fintech at 11 per cent.

A Stronger Outlook Than The Wider European Market

Cyprus’ relative resilience comes at a time when Europe’s broader investment environment remains under pressure. EY recorded 5,026 foreign investment projects across Europe in 2025, down 7 per cent from the previous year. Even so, 60 per cent of businesses surveyed across Europe still expect the region’s attractiveness to improve over the next three years.

For Cyprus, the message is clear: the island retains powerful structural advantages, but preserving investor confidence will depend on reducing costs, improving financing conditions and cutting the friction that still slows business activity.
