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.

Development milestone achieved under the multi-target collaboration and license agreement with Eli Lilly and Company targeting diabetes and metabolic diseases, resulting in a payment to Nxera Launch of proprietary pipeline targeting obesity and chronic weight management, led by an oral small molecule GLP-1 agonist and six additional GPCR-targeted programs Programs leverage Nxera’s NxWave™ structure-based design platform to advance differentiated small molecules aimed at optimizing metabolic efficacy, sustaining weight reduction, and preserving lean mass First patient dosed in Phase 2a trial of investigational cancer immunotherapy HTL0039732 HTL0039732 (also known as NXE0039732) is Nxera’s novel oral EP4 antagonist being investigated to treat a wide range of solid cancers in combination with other immunotherapies Cancer Research UK’s Centre for Drug Development is sponsoring and managing the ongoing trial Financial Highlights for the 12-month Period ended 31 December 2025 Revenue totalled JPY 29,615 million (US$197.9 million*), an increase of JPY 780 million (US$5.2 million) vs. the prior year. 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.

Ad hoc announcement pursuant to Art. 53 LR Exclusive licensing agreement includes USD 40 million upfront comprising USD 30 million in cash and USD 10 million equity investment at CHF 14.91 per share, a 20% premium to the 30-day VWAP. Pratteln, Switzerland, January 8, 2026 – Santhera Pharmaceuticals (SIX: SANN) announces it has signed an exclusive licensing agreement with Nxera Pharma UK Ltd. (“Nxera”) for the development, manufacturing and commercialization of AGAMREE® (vamorolone) for the treatment of Duchenne muscular dystrophy (DMD) in Japan, South Korea, Australia and New Zealand. Nxera is a leading international biopharma company with clinical development and commercial operations for rare and speciality medicines in Japan and the broader Asia-Pacific (APAC) region. Under the terms of the agreement, Santhera will receive an upfront payment of USD 40 million from Nxera, consisting of USD 30 million in cash and USD 10 million as an equity investment in Santhera. The USD 10 million equity investment, through the purchase of c.530k shares, will be priced at CHF 14.91 per share, representing a 20% premium to the 30-day VWAP prior to the day of announcement. These shares will be issued shortly after closing of the agreement and will be subject to a customary lock up period. In addition, Santhera is eligible to receive up to USD 165 million in sales and regulatory milestone payments and will receive double-digit tiered royalties on net sales of AGAMREE in the licensed territories. Nxera will be responsible for securing regulatory approval for AGAMREE in the licensed territories, including conducting a registrational bridging clinical study, and will lead on related commercial and manufacturing activities for the territories. This strategic partnership leverages Nxera's proven commercial capabilities and development and regulatory expertise across the APAC region, particularly in Japan, where there remains a significant unmet medical need for patients living with DMD. In addition to its expertise in developing and commercializing specialty care treatments, such as its lead product PIVLAZ™ (clazosentan), Nxera’s team brings significant prior development and manufacturing experience with vamorolone through its 2023 acquisition of Idorsia’s Japan and APAC business, with members of the former Idorsia (now Nxera) based team in Basel, having historically worked on the product in its earlier stages of development. Dario Eklund, Chief Executive Officer of Santhera, commented : “This strategic partnership represents a significant milestone in our mission to expand global access to AGAMREE and bring meaningful new treatment options to patients with DMD worldwide. Nxera's deep expertise and established infrastructure in Japan and across the wider APAC region, as well as prior experience of vamorolone, make them an ideal partner to unlock the full commercial and clinical potential of AGAMREE in these markets and accelerate access for patients with DMD.” Christopher Cargill, President and Chief Executive Officer of Nxera, added: “We are excited to partner with Santhera to bring AGAMREE to DMD patients in Japan, South Korea, Australia and New Zealand. AGAMREE’s differentiated safety and efficacy pro the potential to fundamentally change the standard of care by enabling early use, full dosing, and long-term treatment, addressing critical limitations of existing steroid therapies currently used in the region.” About AGAMREE® (vamorolone) AGAMREE is a novel drug with a mode of action based on binding to the same receptor as glucocorticoids but modifying its downstream activity. Moreover, it is not a substrate for the 11-β-hydroxysteroid dehydrogenase (11β-HSD) enzymes that may be responsible for local drug amplification and corticosteroid-associated toxicity in local tissues [1-4]. This mechanism has shown the potential to ‘dissociate’ efficacy from steroid safety concerns and therefore AGAMREE is positioned as a dissociative anti-inflammatory drug and an alternative to existing corticosteroids, the current standard of care in children and adolescent patients with DMD [1-4]. In the pivotal VISION-DMD study, AGAMREE met the primary endpoint Time to Stand (TTSTAND) velocity versus placebo (p=0.002) at 24 weeks of treatment and showed a good safety and tolerability profile [1, 4]. The most commonly reported side effects were cushingoid features, vomiting, weight increase and irritability. Side effects were generally of mild to moderate severity. Currently available data show that AGAMREE, unlike corticosteroids, has no restriction of growth [5] and no negative effects on bone metabolism as demonstrated by normal bone formation and bone resorption serum markers [6]. ▼ This medicinal product is subject to additional monitoring. This will allow quick identification of new safety information. Healthcare professionals are asked to report any suspected adverse reactions. References: [1] Dang UJ et al.
