(“Pharming” or “the Company”) (EURONEXT Amsterdam: PHARM/Nasdaq: PHAR) today announced 2026 financial guidance and will highlight its advancing clinical-stage rare disease pipeline, including two major value -creating programs, at a virtual Investor Day taking place later today. The Investor Day will focus on the scientific rationale, clinical st rategy, and long‑term opportunity underpinning Pharming’s pipeline programs in primary immunodeficiencies (PIDs) with immune dysregulation and mitochondrial DNA (mtDNA)‑driven mitochondrial disease. Fabrice Chouraqui, Chief Executive Officer of Pharming, commented: “Pharming’s vision of developing into a leading global rare disease company is grounded in the strength of our two commercial products and our high-value pipeline. We expect our commercial portfolio to continue delivering robust growth, with total revenues between US$ 405 million and US$425 million in 2026 . We are excited to showcase the breadth and quality of our pipeline at today’s Investor Day . Leniolisib and napazimone (KL1333) are being developed for large, underserved rare disease populations with significant unmet need , and are supported by a strong and growing body of biological and clinical evidence. We believe both programs offer substantial long‑term value‑creating potential for Pharming.” 2026 financial guidance: • Total revenues between US$405 million and US$425 million (8% to 13% growth), driven by significant and accelerating growth for Joenja® and continued growth for RUCONEST® • Total operating expenses between US$ 330 million and US$335 million, with the increase driven primarily by an increase in Research & Development expenses related to the ongoing leniolisib Phase II clinical trials and the napazimone (KL1333) pivotal clinical trial

Pipeline overview: Leniolisib – primary immunodeficiencies with immune dysregulation Pharming management will outline the scientific and clinical rationale supporting the expansion of leniolisib into broader patient populations with primary immunodeficiencies (PIDs) with immune dysregulation, beyond its currently approved indication. Two Phase II proof ‑of‑concept clinical trials are ongoing — one in genetically defined PIDs linked to PI3K signaling and one in common variable immunodeficiency (CVID) with immune dysregulation — with top‑line data for both trials expected in the second half of 2026. Leniolisib is an oral, selective phosphoinositide 3 ‑kinase delta (PI3Kδ) inhibitor that is currently approved and marketed as Joenja in the United States, and marketed and/or approved in additional countries, as the first and only targeted treatment for activated PI3Kδ syndrome (APDS) 1, a rare and progressive primary immunodeficiency, for patients 12 years of age and older. APDS represents a genetically defined form within the broader CVID spectrum and serves as a clinically validated proof‑of‑concept for targeting PI3Kδ ‑driven immune dysregulation, supporting the potential applicability of leniolisib across significantly broader PID and CVID patient populations. Napazimone (KL1333)– mtDNA-driven mitochondrial disease Pharming management will outline the scientific and clinical rationale for napazimone (KL1333), the newly named compound being developed for mtDNA-driven mitochondrial disease, which has the potential to become the first standard of care in this setting, if approved. The pivotal FALCON clinical trial is ongoing and remains on track for a readout in 2027. Napazimone (KL1333) is an investigational therapy being developed for adult patients with primary mitochondrial disease caused by mitochondrial DNA (mtDNA) mutations — a rare and debilitating condition characterized by impaired energy production, significant fatigue and muscle weakness (myopathy), and reduced life expectancy. Clinical expert perspectives The Investor Day will feature presentations from leading clinical experts, providing context on disease biology, unmet medical need, and the potential role of Pharming’s programs. • Jocelyn Farmer, MD, PhD, Lahey Hospital & Medical Center — an internationally recognized authority on CVID and immune dysregulation • Amel Karaa, MD, Massachusetts General Hospital, Harvard Medical School — an internationally recognized authority on mitochondrial medicine 1 FDA press release published on March 24, 2023, titled FDA approves first treatment for activated phosphoinositide 3 -kinase delta syndrome.
