Transaction expands Ligand’s royalty portfolio to more than 200 assets and adds seven new commercial products Bolsters and diversifies Ligand’s long-term compounding growth, adding a complementary portfolio across development stages, therapeutic areas, and modalities to broaden patient access and improve lives Acquisition is expected to be immediately accretive to Ligand adjusted EPS; Ligand increases 2026 adjusted EPS guidance to $8.50-$9.50 1 and expects the transaction to be accretive by $1.50 per share to adjusted EPS in 2027 2 Ligand to hold investor call at 8:00 a.m. ET today JUPITER, Fla. and EMERYVILLE, Calif., April 27, 2026 (GLOBE NEWSWIRE) -- Ligand Pharmaceuticals Incorporated (Nasdaq: LGND) and XOMA Royalty Corporation (“XOMA Royalty”) (Nasdaq: XOMA), both biotechnology royalty aggregators, today announced that the companies have entered into a definitive agreement under which Ligand will acquire XOMA Royalty for $39.00 per share of common stock in cash, for a total equity value of approximately $739 million. XOMA Royalty stockholders are expected to separately receive one non-transferable Contingent Value Right (“CVR”) per share entitling the holder to receive a portion of 75% of the net proceeds that may result from certain pending litigation at XOMA Royalty. The cash purchase price at close represents an approximately 14% premium to XOMA Royalty’s 30 trading day volume weighted average price as of April 24, 2026, the last trading day prior to announcement of the transaction. "The acquisition of XOMA Royalty presents a compelling opportunity for us to strengthen and diversify our portfolio across all stages of clinical development and accelerate our long-term profitable growth. This acquisition will add seven marketed products and nearly double our portfolio of Phase 2 and 3 assets, which we believe will create significant value for our stockholders, all through a single transaction,” said Todd Davis, CEO of Ligand. “The XOMA Royalty team has built a robust portfolio of complementary biopharmaceutical assets, and this acquisition will enable us to further grow and diversify in areas such as ophthalmology, oncology, CNS and rare diseases. With XOMA Royalty, we believe we will now be in an even stronger position to leverage our expertise and capital base to support broader patient access and advance late-stage clinical programs in a way that enhances patient outcomes and improves lives. With this agreement, Ligand adds over 120 commercial, clinical, and preclinical stage assets to its broad and growing royalty portfolio highlighted by Roche’s VABYSMO® (faricimab-svoa), Day One Pharmaceuticals’ OJEMDA™ (tovorafenib), Zevra Therapeutics’ MIPLYFFA™ (arimoclomol), and 14 programs in late-stage development, highlighted by Takeda’s mezagitamab and certain assets from Takeda’s externalized asset portfolio, including osavampator, volixibat and OHB-607. The addition of the XOMA Royalty portfolio is expected to increase Ligand’s long-term growth profile. “After evaluating a broad range of strategic and financing alternatives, we believe combining our diverse portfolio with a company that shares our commitment to helping the biopharmaceutical industry thrive represents the most compelling outcome for XOMA Royalty’s stockholders,” said Owen Hughes, CEO of XOMA Royalty. “The structure delivers to our stockholders both the intrinsic value of XOMA’s portfolio today and the optionality associated with our ongoing litigation with Janssen Biotech (now Johnson & Johnson Innovative Medicine) via the CVR. Since 2023, we significantly scaled our portfolio with the addition of multiple assets and two platform technologies, enabling numerous upcoming regulatory and clinical catalysts beginning in 2026 and continuing over the next several years. We believe coupling Ligand’s business development capabilities, portfolio management expertise plus the inherent financial synergies from this transaction position the combined company to maximize long-term value across the combined portfolio.” Transaction Terms Under the terms of the merger agreement, Ligand will acquire all the outstanding shares of common stock of XOMA Royalty for $39.00 per share in cash. The cash consideration for the transaction is expected to be funded with Ligand’s existing cash on hand and borrowings under Ligand’s existing credit facility. XOMA Royalty’s Series X Convertible Preferred Stock is expected to be converted into shares of common stock at its stated fixed price prior to closing, whereas the outstanding shares of Series A Preferred Stock and Series B Preferred Stock are expected to be redeemed. XOMA Royalty stockholders also will receive one CVR per share. The CVRs are intended to provide XOMA Royalty stockholders with the opportunity to receive certain net proceeds, if any are recovered, from certain ongoing litigation with regard to XOMA Royalty’s dispute with Janssen Biotech regarding the commercialization of TREMFYA®. Timing and Approvals The transaction has been unanimously approved by the Ligand and XOMA Royalty Boards of Directors. Entities affiliated with BVF Partners, which own approximately 21% of the outstanding shares of XOMA Royalty common stock and approximately 44% assuming the conversion of their Series X Convertible Preferred Stock, have agreed to convert such shares into shares of XOMA Royalty common stock prior to closing and have entered into a voting agreement in support of the transaction. In addition, XOMA Royalty’s directors and officers have also entered into voting agreements in support of the transaction. The transaction is expected to close in the third quarter of 2026, subject to customary closing conditions, approval by XOMA Royalty stockholders and the receipt of certain regulatory approvals. Financial Guidance Update The transaction is expected to close in the third quarter of 2026 and to be immediately accretive to Ligand earnings per share.

Oak Hill Bio and Chiesi Group Announce Enrollment of First Patients in Australia and Japan in the Phase 2b Clinical Study Evaluating OHB-607 for the Prevention of Bronchopulmonary Dysplasia, a Leading Cause of Chronic Lung Disease in Premature Infants. Multi-centre study, re-launched in May 2024, builds on prior Phase 2a clinical data[1], demonstrating a reduction in severe bronchopulmonary dysplasia (BPD). OHB-607 is being investigated as a potential breakthrough in the respiratory care of extremely preterm neonates.[2] Oak Hill Bio and Chiesi Group are advancing the development of OHB-607 through a strategic license and development partnership. Cambridge (United States) and Parma (Italy), March 13, 2026 - Oak Hill Bio, a clinical-stage company specializing in neonatology and rare disease therapeutics, and Chiesi, an international, research-driven biopharmaceutical group, have announced the enrolment of patients in Australia and Japan in their multinational Phase 2b clinical study evaluating the efficacy and safety of OHB-607. This investigational drug candidate aims at preventing severe complications in extremely premature infants, including bronchopulmonary dysplasia (BPD), a serious condition for which there are no approved therapies. The study is already enrolling patients in North America and the EU. “As advances in neonatal intensive care allow more extremely premature infants to survive to discharge, increasing numbers of infants are living with BPD, which remains the most common cause of chronic lung disease and the dominant complication of extreme prematurity,” said Dr. Victoria Niklas, Chief Medical Officer of Oak Hill Bio. “OHB-607 is designed to restore physiologic IGF-1 levels during a critical window of lung development, targeting pathways disrupted after extremely premature birth.” ‍ Neonatal Care in Australia and Japan The impact of our partnership in Australia is bolstered by national data from the Report of the Australian and New Zealand Neonatal Network (ANZNN) 2023[3], which shows that rates of BPD[3] among infants born before 32 weeks’ gestation have increased steadily over the past decade. The highest rates are reported in infants less than 26 weeks’ gestation, where BPD prevalence rose from approximately 78% in 2014 to nearly 90% in 2023, with rates in infants born between 26–28 weeks’ gestation increasing from around 40% to 50% over the same period. Neonatal Research Network of Japan Database highlights remarkable progress in the survival rates for infants born at 23-28 weeks of gestation, reaching nearly 90%[4]. However, about 50% of these infants develop BPD, with more than half experiencing severe forms of the condition. These facts underscore the urgent need for innovative therapeutic options like OHB-607. “The inclusion of Australian and Japanese patients in this study reflects the shared commitment of Chiesi and Oak Hill Bio to tackle urgent neonatal health challenges on a global scale,” said Diego Ardigò, Executive Vice President, Global Research & Development, Chiesi Group. “The high incidence of BPD in Australia and Japan highlights the critical need for innovative therapeutic solutions, and we believe addressing the medical needs of the most vulnerable patients is not only a scientific endeavour but also a moral responsibility”. ****** About the FOOTPRINTS Phase 2b Study The Phase 2b clinical study is a multinational, multicentre, randomized, open-label, two-arm study designed to evaluate the efficacy and safety of OHB-607 compared to standard neonatal care for preventing BPD and related complications in extremely preterm infants born between 23 and 28 weeks of gestation. The study, which opened in the United States in May 2024, is now enrolling patients in Australia. The study aims to recruit up to 338 patients globally, including North America, Europe, and Japan, and infants from Australia. OHB-607 will be administered via continuous intravenous infusion within 24 hours of birth, continuing until infants reach 30 weeks postmenstrual age, in addition to standard neonatal care. The primary endpoint of the study is the reduction in the incidence of severe BPD or mortality by 36 weeks postmenstrual age compared to extremely premature infants receiving standard neonatal care alone. The study will also evaluate the impact of OHB-607 on weaning from respiratory technology support through 12 months corrected age as a longer-term respiratory outcome measure, the impact on neurodevelopment, and the incidence of other complications of prematurity, including intraventricular haemorrhage (bleeding in the brain) and retinopathy of prematurity (vision impairment and blindness). The study will use a modified National Institute of Child Health and Human Development (NICHD) score to grade BPD severity, enabling comparison of infants with the most severe form of the disease. For additional information and to learn more about the trial registration, please visit https://clinicaltrials.gov/study/NCT03253263 About OHB-607 OHB-607 is the recombinant form of human insulin-like growth factor-1 (IGF-1) complexed with its main binding protein (rhIGFBP-3). IGF-1 is a key driver of the growth and gestational development of vital organs, including the lung, eye, and brain. Mothers are the primary source of IGF-1 for the developing foetus until about 30 weeks of gestational age, when the fetal liver takes over. As a result, infants born before 28 weeks of gestation have low IGF-1 levels, which is believed to lead to organs failing to grow and develop normally. Following preterm birth, IGF-1 levels decrease rapidly and remain low for the first weeks of life relative to corresponding fetal levels in utero. Longitudinal studies report an association between lower serum IGF-1 levels at birth in extremely preterm infants and an increased risk of BPD, retinopathy of prematurity, neurodevelopmental and overall growth impairment. This provides a rationale for evaluating OHB-607 to restore IGF-1 to levels present in utero in a full-term pregnancy, potentially supporting the normal growth and development of the lung and other organs[4]. OHB-607 has the potential to be the first major breakthrough in respiratory therapy for extremely preterm infants since lung surfactants were first approved more than 30 years ago. About Bronchopulmonary Dysplasia (BPD)[5] BPD is the most common complication of prematurity, characterized by chronic lung disease in extremely preterm infants. Beyond its immediate impact on lung function, BPD can also lead to higher mortality rates, prolonged hospitalization, increased healthcare costs, as well as long-term respiratory morbidity and neurodevelopmental disability[6],[7]. The pathogenesis of BPD is multifactorial and not fully understood, but gestational age remains the most critical factor in predicting the condition. Additional factors, including birth weight, growth restriction, lung function, and gender, may influence the severity of BPD. Infants requiring prolonged oxygen therapy or mechanical ventilation are at heightened risk, as these life-sustaining practices can cause direct and indirect damage to the developing lungs. OHB-607 represents a promising therapeutic advance, with the potential to support lung development and reduce reliance on intensive respiratory support. By addressing the root causes of lung injury, OHB-607 may help mitigate the severity of BPD and its associated long-term complications. ****** About Oak Hill Bio Oak Hill Bio Ltd is a clinical-stage rare-disease therapeutics company developing life-changing medicines for extremely preterm infants and patients with rare diseases.
