Tokyo, Japan and Cambridge, UK, 13 February 2026 – Nxera Pharma Co., Ltd. (“Nxera” or “the Company”; TSE 4565) provides an update on operational activities and reports its consolidated results for the fourth quarter and 12 months ended 31 December 2025. The full report can be viewed here . Christopher Cargill, President and CEO of Nxera Pharma, commented : “2025 was a year of disciplined execution and strategic progress for Nxera, as we continued to build a more focused, resilient and scalable biopharmaceutical business with a growing commercial footprint in Japan and a maturing pipeline. “In doing so, we further strengthened our commercial foundations in Japan and the broader APAC region, with PIVLAZ® for the prevention of cerebral vasospasm after aneurysmal subarachnoid haemorrhage firmly established as the standard of care in Japan. We made continued progress with QUVIVIQ™ for insomnia, including manufacturing enhancements to support increasing demand and improve long-term profitability. We also expanded our late- and commercial-stage portfolio through targeted business development, most notably with the licensing of vamorolone for Duchenne Muscular Dystrophy from Swiss specialty pharmaceutical company Santhera as well as new regional partnerships for daridorexant. “Across our pipeline, 2025 delivered important clinical and strategic milestones. Our partners continued to advance multiple programs into later-stage development, generating approximately US$35 million in milestone payments. Importantly, Neurocrine’s initiation of Phase 3 studies with NBI-‘568 marked a significant step forward for our most advanced neuroscience asset from a portfolio of muscarinic agonists discovered by Nxera and licensed to Neurocrine. “At the same time, we took decisive steps to sharpen our focus and enhance our path to profitability, implementing a targeted restructuring and prioritizing programs and platforms with the greatest long-term potential for value creation. These were hard decisions and were not taken lightly but are crucial to positioning Nxera for future success. I am very grateful for the important contributions made by all our employees over the last 12 months towards this goal. These steps included regaining full rights to our GPR52 agonist program, following which Nxera plans to explore all strategic opportunities for this promising clinical asset. In addition, we launched a new proprietary pipeline in obesity and metabolic disease, leveraging the full power of our NxWave™ platform to address important areas of emerging patient need in this highly attractive commercial space. “As we enter 2026, Nxera is well positioned with multiple upcoming clinical and regulatory catalysts and a clear strategic focus. I am extremely proud of what our teams have delivered during the year, and I am confident in our ability to build on this momentum as we continue to advance innovative medicines for patients in Japan and around the world.” Operational Highlights for Q4 2025 Growth in PIVLAZ® (clazosentan sodium) 150mg sales continued in Japan Clear standard of care in Japan with neurosurgeons for prevention of cerebral vasospasm in patients with aneurysmal subarachnoid haemorrhage (aSAH) Market share increased from 69% in 2024 to 74% in 2025 Q4 2025 net sales of JPY 4,545 million (US$30.4 million), FY 2025 net sales of JPY 13,511 million (US$90.3 million), representing 6.8% growth vs FY 2024.

This increase reflects a balance of factors. Although the number of milestones achieved increased to seven in the current consolidated financial year from five in the previous consolidated financial year, milestone income is inherently volatile and the amount received per milestone was lower than in the previous consolidated financial year. In contrast, revenues from commercialized products performed strongly, with PIVLAZ® increasing 6.8% compared with the previous consolidated financial year to JPY 13,511 million (US$90.3 million), and QUVIVIQ® increasing 223.9% compared with the previous consolidated financial year to JPY 4,327 million (US$28.9 million). R&D expenses totalled JPY 14,466 million (US$96.7 million), an increase of JPY 2,650 million (US$17.7 million) vs. the prior year. This increase primarily reflects increased R&D investment in the clinical-stage pipeline and in the obesity and metabolic disease area, as well as the impact of yen depreciation. SG&A expenses totalled JPY 15,225 million (US$101.7 million), a decrease of JPY 790 million (US$5.3 million) vs. the prior year. This decrease was primarily due to the Company’s targeted cost reduction initiatives, resulting in lower sales-related expenses. Operating loss totalled JPY 8,462 million (US$56.5 million) vs. an operating loss of JPY 5,423 million (US$35.9 million) in the prior year. Loss before income tax totalled JPY 14,950 million (US$99.9 million) vs. a loss before income tax of JPY 4,662 million (US$30.8 million) in the prior year. In addition to the higher operating loss, this was primarily due to higher finance costs for the financial year under review. The Company recorded expenses associated with amendments to the terms of its corporate bonds and a loss on remeasurement of contingent consideration following the positive progress of certain R&D programs in an acquired business. Net loss totalled JPY 12,530 million (US$83.7 million) vs. a net loss of JPY 4,838 million (US$32.0 million) in the prior corresponding period. Core operating loss** totalled JPY 352 million (US$2.4 million) vs. a core operating profit of JPY 3,606 million (US$23.9 million) in the prior year. Cash and cash equivalents as at 31 December 2025 amounted to JPY 20,365 million (US$130.2 million) having decreased by JPY 11,903 million (US$75.6 million) from the beginning of the year. *Convenience conversion to US$ at the following rates: FY 2025: 1US$ =149.65 JPY; FY 2024: 1US$ =151.43 JPY 31 Dec 2025: 1US$ = 156.47 JPY; 31 Dec 2024: 1US$ = 156.83 JPY ** Core operating profit / loss is an alternative performance measure which adjusts for material non-cash costs and one-off costs in order to provide insights into the recurring cash generation capability of the core business. –END– About Nxera Pharma Nxera Pharma is a technology powered biopharma company in pursuit of new specialty medicines to improve the lives of patients with unmet needs in Japan and globally.
