Nicholas Nuclear Income ETF (NUKX) is an actively managed exchange-traded fund that seeks high current income and capital appreciation through investments in nuclear energy-related companies and projects. The fund primarily allocates to equity securities of issuers engaged in nuclear power generation, uranium mining and production, nuclear fuel services, reactor construction and maintenance, and related technologies; it also invests in fixed-income securities, preferred stocks, and other income-generating instruments tied to the nuclear sector. NUKX targets institutional and retail investors seeking exposure to the growing clean energy transition, with a focus on companies benefiting from advancements in small modular reactors (SMRs), nuclear fuel recycling, and global decarbonization efforts; its portfolio emphasizes U.S.-listed securities but includes international holdings from operations in North America, Europe, and Asia. Launched in 2024 and domiciled in the United States with principal operations managed by its sponsor, the fund underwent a significant strategic expansion in late 2025 with the addition of a dedicated allocation to next-generation nuclear technology firms following a seed capital raise of approximately $150 million; in early 2026, NUKX announced a partnership with a leading uranium producer to enhance yield through proprietary income strategies and launched a new share class aimed at high-net-worth individuals amid surging demand for nuclear-themed investments.
