According to coherent market insights, the Pharmaceutical Market is expected to grow at a CAGR of 8.1% during 2025 to 2032. Currently, the market is at USD 1.81 Tn in 2025 and is expected to be around USD 3.12 Tn by 2032. This major growth trajectory is driven by the rising healthcare demands, advancements in drug development, and increasing investments in biopharmaceutical research worldwide, positioning the market for robust expansion over the forecast period.

Staffan Schüberg, ESTEVE's Chief Executive Officer stated: "We are excited to welcome the Infusion Specialty Therapies Business Unit and look forward to welcoming TerSera's talented team to ESTEVE. This acquisition perfectly aligns with our strategic vision of providing highly specialized solutions where there is a significant unmet medical need. By adding Quzyttir® to our portfolio and expanding to the US market with Prialt®, we not only strengthen our expertise in highly specialized therapies but also accelerate our expansion in the United States—the world's largest pharmaceutical market."

Their expertise and core areas of focus make them the ideal future owner for IST." said Edward Donovan, Chief Executive Officer of TerSera.
