- U.S. NRC technical report submission targeted for February 2026, advancing SOLO™ along its licensing pathway.
- Completion of the SOLO™ Phenomena Identification and Ranking Table (PIRT), delivering a structured, expert-driven assessment of the key physical phenomena governing system behavior to inform modeling, design, and safety decisions.
- SOLO™ PIRT was developed by a formal expert panel, in alignment with U.S. NRC guidance and industry best practices.
- PIRT outcomes will directly support upcoming licensing filings, including the Preliminary Safety Analysis Report (“PSAR”).
- To recognize this milestone and the panel’s contributions, Terra Innovatum hosted the PIRT expert panel at its new headquarters in Lucca, Italy.
NEW YORK, Feb. 02, 2026 (GLOBE NEWSWIRE) — Terra Innovatum Global N.V. (“Terra Innovatum” or the “Company”) (NASDAQ: NKLR), a developer of micro-modular nuclear reactors announced today the completion of the Phenomena Identification and Ranking Table (PIRT) for its SOLO™ microreactor, a key technical milestone supporting the company’s U.S. licensing and safety analysis program. A technical report documenting the PIRT methodology and results is scheduled for submission to the U.S. Nuclear Regulatory Commission (NRC) planned for February 2026.
In Picture: Members of the Terra Innovatum Global team and SOLO™ PIRT expert panel in “Villa Nannini”, Terra Innovatum’s New Headquarters (Lucca, Italy), following the completion of the PIRT, ahead of the planned US NRC submittal.
Cesare Frepoli – Co-Founder, COO & Licensing Director stated: “This milestone reflects our disciplined, risk-informed licensing strategy and our commitment to technical rigor from the earliest stages of design. By applying a transparent, NRC-aligned PIRT process, we are ensuring that safety-significant phenomena are identified and addressed in a manner that supports efficient, predictable regulatory engagement. Submission of the PIRT technical report to the NRC in February represents an important step in Terra Innovatum’s broader U.S. licensing strategy for the SOLO™ microreactor, supporting both first-of-a-kind deployment and a scalable framework for future applications.”
Alessandro Petruzzi – Co-Founder & CEO continued: “The PIRT process is a structured, expert-driven approach used to identify and rank the physical phenomena most important to reactor safety and system performance across normal operation, anticipated operational occurrences, and postulated accident conditions. Completion of this work strengthens the technical foundation underpinning SOLO™’s safety analysis methods, modeling assumptions, and evaluation approaches that support key licensing deliverables.
We were especially proud to host the PIRT expert panel at Terra Innovatum’s new headquarters in Lucca, Italy, marking an important milestone for both the SOLO™ program and our growing global organization. Developed through a formal expert panel process consistent with established U.S. NRC guidance and industry best practices for advanced and non-power reactor designs, the SOLO™ PIRT will directly inform downstream licensing activities, including topical reports and safety analyses supporting the Preliminary Safety Analysis Report (PSAR).”

FORWARD LOOKING STATEMENTS
This press release includes “forward-looking statements” within the meaning of the federal securities laws, including, but not limited to, opinions and projections prepared by Terra Innovatum’s management. Forward-looking statements generally relate to future events or future financial or operating performance, including pro forma and estimated financial information, and other “forward-looking statements” (as such term is defined in the Private Securities Litigation Reform Act of 1995). For example, projections of future sales, EBITDA, Adjusted EBITDA and other metrics are forward-looking statements. The recipient can identify forward-looking statements because they typically contain words such as “outlook,” “believes,” “expects,” “ will,” “projected,” “continue,” “increase,” “may,” “should,” “could,” “seeks,” “predicts,” “intends,” “trends,” “plans,” “estimates,” “anticipates” or the negatives or variations of these words or other comparable words and/or similar expressions (but the absence of these words and/or similar expressions does not mean that a statement is not forward-looking). These forward-looking statements specifically include, but are not limited to, statements regarding estimates and forecasts of financial and performance metrics, projections of market opportunity and market share and the potential success of Terra Innovatum’s strategy and expectations. Forward-looking statements, opinions and projections are neither historical facts nor assurances of future performance.

Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of Terra Innovatum’s control. These uncertainties and risks may be known or unknown. Factors that may cause actual results to differ materially from current expectations include, but are not limited to: changes in domestic and foreign business, market, financial, political and legal conditions; failure to realize the anticipated benefits of the proposed business combination; risks relating to the uncertainty of the projected financial information with respect to Terra Innovatum; future global, regional or local economic and market conditions; the development, effects and enforcement of laws and regulations; Terra Innovatum’s ability to manage future growth; Terra Innovatum’s ability to develop new products and services, bring them to market in a timely manner, and make enhancements to its platform; the effects of competition on Terra Innovatum’s future business; and the outcome of any potential litigation, government and regulatory proceedings, investigations and inquiries. If any of these risks materialize or the Terra Innovatum’s assumptions prove incorrect, actual results could differ materially from the results implied by the forward-looking statements contained herein. In addition, forward-looking statements reflect Terra Innovatum’s expectations and views as of the date of this presentation.
