Terra Innovatum Global N.V. (NASDAQ: NKLR) has been added to the Solactive Global Uranium & Nuclear Components Total Return Index, effective at the open of markets on August 3, 2026, when the index’s regular rebalancing became operative. The index serves as the benchmark for the Global X Uranium ETF (NYSE Arca: URA), one of the largest exchange-traded funds focused on uranium and nuclear energy.
The inclusion was announced by Solactive AG on July 27, 2026, as part of its periodic index composition review. Frankfurt-based Solactive AG is an independent index provider whose benchmarks underpin ETFs and other investment products globally. The decision to include Terra Innovatum reflects the company’s growing profile as a Nasdaq-listed micro-reactor developer at an advanced stage of commercialization.
Terra Innovatum was founded in Italy six years ago, with its operational base in Lucca, and completed a business combination with GSR III Acquisition Corp. in October 2025, listing its common shares on Nasdaq under the ticker NKLR. Its flagship product is the SOLO reactor: a compact micro-reactor designed to deliver 1 MWe of continuous electrical output, plus up to 4 MW of low-temperature heat or 5 MW of high-temperature steam. The reactor is engineered to operate for 15 years without refueling, with a potential service life of 45 years. First commercial deployment is targeted for 2028.
SOLO is designed for environments where conventional grid power is unavailable or unreliable, including data centers, industrial sites, remote communities, logistics facilities, and medical installations. Its modular architecture aims to streamline deployment. Entry into the Solactive index broadens Terra Innovatum’s visibility among a wider pool of institutional and passive investors tracking the nuclear sector, complementing the access already built with active and fundamental investors. Thematic and passive capital has become a meaningful driver of demand for companies in this space.
On the financial side, the company remains pre-revenue and had accumulated a deficit of approximately $607 million as of December 31, 2025. It has, however, raised around $130 million through trust funds and equity financing to support SOLO’s licensing, manufacturing, and deployment activities. The company also submitted a regulatory engagement plan to the U.S. Nuclear Regulatory Commission in January 2025, a key milestone on the path to reactor certification.
Inclusion in the benchmark of the sector’s most widely followed uranium and nuclear ETF represents a concrete marker of maturity for Terra Innovatum. Should the SOLO reactor reach its first commercial deployment by 2028 on schedule, the company will be positioned to convert today’s financial market visibility into real contracts. The project’s core remains Italian, making Terra Innovatum one of the most advanced cases of compact nuclear technology developed in Europe.
