[Ad hoc announcement pursuant to Art. 53 LR] Roche reports strong sales growth of +6% at constant exchange rates in the first quarter of 2026; -5% in CHF due to the significant appreciation of the Swiss franc

• Group sales were +6% at constant exchange rates (CER)¹, -5% when reported in CHF and +9% in USD², in the first three months, driven by high demand for our innovative medicines and diagnostics.
• Pharmaceuticals Division sales were +7% at CER, -4% when reported in CHF and +10% in USD, due to continued high growth in sales of medicines for the treatment of severe diseases; Xolair (chronic hives, food allergies), Phesgo (breast cancer), Hemlibra (haemophilia A), Vabysmo (severe eye diseases) and Ocrevus (multiple sclerosis) were the top growth drivers.
• Diagnostics Division sales were +3% at CER, -7% when reported in CHF and +7% in USD, as demand for core lab and pathology solutions more than offset the impact of healthcare pricing reforms in China.
• Highlights:
  • Positive data for: fenebrutinib for multiple sclerosis (phase III), Gazyva/Gazyvaro for an autoimmune condition affecting kidney function (phase III); and petrelintide for obesity (phase II)
  • CE mark for new Elecsys NfL blood test to detect neuroinflammation in multiple sclerosis, representing a breakthrough in disease management
  • Launch of the cobas MPX-E assay, a new 4-in-1 test to screen blood donors for HIV and hepatitis viruses

Group sales
In the first three months of 2026, Roche sales were +6% at CER, -5% when reported in CHF, to CHF 14.7 billion due to strong demand for pharmaceutical products and diagnostic solutions. The appreciation of the Swiss franc against most currencies, notably the US dollar, had a significant impact on the results reported in Swiss francs compared to constant exchange rates.

Sales in the Pharmaceuticals Division were +7% at CER, -4% when reported in CHF, to CHF 11.5 billion, with medicines for severe diseases continuing their strong growth.

The top five growth drivers – Xolair, Phesgo, Hemlibra, Vabysmo and Ocrevus – achieved total sales of CHF 5.3 billion, an increase of 14% at CER, or 2% in CHF, compared to the first three months of 2025.

Sales of products with expired patents (Avastin, Herceptin, MabThera/Rituxan, Lucentis and Actemra/RoActemra) decreased by a combined CHF 0.1 billion at CER, or CHF 0.2 billion in CHF.

In the United States, sales were +5% at CER, -9% when reported in CHF, due to continued growth of Xolair and continuing uptake of Hemlibra, Polivy (blood cancer), Ocrevus and Vabysmo. This growth more than compensated for the lower sales of Perjeta (breast cancer) and Kadcyla (breast cancer).

Sales in Europe were -1% at CER, or -4% when reported in CHF, due to lower sales of Polivy, the impact of biosimilar competition on Actemra/RoActemra and Perjeta (breast cancer) due to conversion to Phesgo. This decrease was partially offset by the demand for Ocrevus and Evrysdi (spinal muscular atrophy).

In Japan, sales were +14% at CER, -3% when reported in CHF, mainly due to product supply to third parties, as well as a strong uptake of Hemlibra, Vabysmo and Polivy. Sales growth was partially offset by the decline in sales of Tamiflu and the impact of biosimilar erosion on Avastin.

Sales in the International region were +16% at CER, or +6% when reported in CHF, led by Phesgo, Vabysmo, Polivy, Alecensa (lung cancer) and Ocrevus and partially offset by lower sales of influenza medicines Xofluza and Tamiflu. In China, sales were +14% at CER, or +5% when reported in CHF, as the uptake of Phesgo, Polivy and Vabysmo gained momentum following their inclusion in the government drug reimbursement list. The continued roll-out of Alecensa was the other growth driver. The increase was partially offset by lower sales of Xofluza and Perjeta.

The Diagnostics Division’s sales were +3% at CER, -7% when reported in CHF, to CHF 3.3 billion as growth in demand for core lab and pathology solutions more than offset the impact of healthcare pricing reforms in China.

Sales in the Europe, Middle East and Africa (EMEA) region were +3% at CER, -2% when reported in CHF, driven by higher sales of clinical chemistry and immunodiagnostic products. In North America, sales were +6% at CER, -7% when reported in CHF, with growth across core, pathology and molecular lab areas. Sales in Asia-Pacific were -5% at CER, or -15% when reported in CHF, due to the healthcare pricing reforms in China. In Latin America, sales growth was +10% at CER, or 0% when reported in CHF.

Pharmaceuticals: key developments

Compound	Milestone
Regulatory
Gazyva/Gazyvaro Lupus	FDA accepts application for Gazyva/Gazyvaro for the treatment of the most common form of lupus The filing was accepted based on phase III ALLEGORY data for Gazyva/Gazyvaro showing a significant reduction in disease activity compared with placebo in people with systemic lupus erythematosus (SLE). If approved, Gazyva/Gazyvaro would be the first anti-CD20 therapy to directly target B cells in SLE, potentially becoming the new standard of care for this condition. SLE is a potentially life-threatening autoimmune disease affecting more than three million people worldwide – achieving better disease control can reduce flares and may prevent irreversible organ damage.   More information: Media Release, 21 April 2026
Giredestrant Breast cancer	FDA accepts New Drug Application for giredestrant in ESR1-mutated, ER-positive advanced breast cancer Filing was accepted based on phase III data showing giredestrant plus everolimus reduced the risk of disease progression or death by 44% and 62% in ITT and ESR1-mutated populations, respectively, versus standard-of-care endocrine therapy plus everolimus. Strength of evERA data demonstrates the potential for giredestrant combination to help address resistance to standard-of-care therapies, and that it could be the first and only oral SERD combination approved in the post-CDK4/6 inhibitor setting. The FDA has set a Prescription Drug User Fee Act date of 18 December 2026.   More information: Media Release, 20 February 2026
Phase III, pivotal and other key read-outs
Enspryng MOGAD	Enspryng reduces risk of relapses by 68%, demonstrating potential to become first treatment for MOGAD The phase III METEOROID study met its primary endpoint in patients with myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD). MOGAD is a rare autoimmune disease of the central nervous system characterised by unpredictable attacks of the optic nerves, spinal cord or brain that are often severe and debilitating. The data will be submitted to the regulatory authorities.   More information: Media Release, 21 April 2026
Giredestrant Breast cancer	Roche provides update on phase III persevERA study in ER-positive advanced breast cancer The persevERA breast cancer study did not meet the primary objective of a statistically significant improvement in progression-free survival, but a numerical improvement was observed. Giredestrant plus palbociclib was well tolerated and adverse events were consistent with the known safety profiles of each individual treatment. The FDA recently accepted the New Drug Application based on evERA data; phase III lidERA data has been submitted to the FDA.   More information: Media Release, 9 March 2026
Petrelintide Obesity	Roche announces positive phase II results for petrelintide, an amylin analogue developed for people living with overweight and obesity Petrelintide achieved up to 10.7% mean body weight reduction at week 42 versus 1.7% with placebo (p-value <0.001) while demonstrating placebo-like tolerability. At the maximally effective dose, there were no cases of vomiting and no treatment discontinuations due to gastrointestinal adverse events. The data support further development of petrelintide in chronic weight management as monotherapy and its tolerability profile also confirms its value as a combination partner.   More information: Media Release, 5 March 2026
Fenebrutinib Multiple sclerosis	Fenebrutinib confirms its potential as first and only BTK inhibitor for relapsing and primary progressive multiple sclerosis (MS) in third positive phase III study (FENhance 1) FENhance 1 met its primary endpoint, showing that investigational fenebrutinib significantly reduced relapses by 51% compared to teriflunomide in relapsing multiple sclerosis (RMS), which is consistent with FENhance 2 results showing 59% reduction. FENhance 1 is the final study read-out of the fenebrutinib pivotal clinical development programme in MS, following positive results for FENhance 2 in RMS and for FENtrepid in primary progressive multiple sclerosis (PPMS). Fenebrutinib has the potential to become the first and only high-efficacy oral, brain-penetrant treatment for both RMS and PPMS, showing a profound benefit on relapsing and progressive disease biology.   More information: Media Release, 2 March 2026
Gazyva/Gazyvaro Membranous nephropathy	Roche announces positive phase III results for Gazyva/Gazyvaro in primary membranous nephropathy, marking a significant milestone in treatment of this autoimmune disease MAJESTY, the first global phase III study in primary membranous nephropathy, met its primary endpoint of complete remission at two years. Up to 30% of people with membranous nephropathy progress to kidney failure over 10 years despite current treatment approaches; achieving complete remission can help delay or prevent this. Gazyva/Gazyvaro could become the first approved treatment for primary membranous nephropathy, having already achieved positive results in lupus nephritis, systemic lupus erythematosus and idiopathic nephrotic syndrome.   More information: Media Release, 16 February 2026
Fenebrutinib Multiple sclerosis	Fenebrutinib is the first investigational medicine in over a decade that reduces disability progression in primary progressive multiple sclerosis (PPMS) Late-breaking phase III FENtrepid results presented at the Americas Committee for Treatment and Research in Multiple Sclerosis (ACTRIMS) Forum 2026 show investigational fenebrutinib met its primary endpoint of non-inferiority compared to the current standard of care, Ocrevus, in reducing disability progression in PPMS. Fenebrutinib numerically reduced the risk of disability progression by 12% compared to Ocrevus as early as 24 weeks; additional analysis showed potential benefit in upper limb function. Fenebrutinib has the potential to become a first-in-class therapy in multiple sclerosis, as an oral, brain-penetrant BTK inhibitor for PPMS and relapsing multiple sclerosis (RMS)   More information: Media Release, 7 February 2026
