A&C Bio Buffer’s custom buffer and chemical blend portfolio complements Aceto’s growing manufacturing footprint and strengthens its presence in Europe


PORT WASHINGTON, NY— October 12, 2021— Aceto, a leading global provider of specialty materials for life sciences and advanced technology end markets, announced today its acquisition of A&C Bio Buffer Ltd, a GMP (Good Manufacturing Practices) manufacturer of custom buffer and chemical blend products used in the manufacturing of biopharmaceutical drug products. This transaction complements Aceto’s acquisition earlier this year of A&C, a global manufacturer of GMP specialty excipients and custom process solutions, and reinforces the company’s expanded business development efforts in the biopharmaceutical sector.


“A&C Bio Buffer is a natural add-on to our acquisition of A&C and aligns with our commitments to the biopharmaceutical space,” said Gilles Cottier, Chief Executive Officer of Aceto. “It is a nimble, highly customer-centric organization serving some of the top biopharmaceutical manufacturers in Europe. Its rapid growth reflects a reputation for service and quality, which recently led to its key role in the raw material supply chain for COVID-19 vaccines. A&C Bio Buffer enhances our growing European manufacturing footprint and commercial presence. We believe the shared lineage reflected in A&C Bio Buffer’s skills, culture and customer focus will further support our evolution as a leading supplier of critical raw materials in the life sciences sector.”


A&C Bio Buffer GMP manufactures over 50 products including biological buffers, process solutions, cleaning solutions and WFI (Water for Injection) in its state-of-the-art facility in Limerick, Ireland.  A&C Bio Buffer’s combination of advanced manufacturing capabilities, expertise, robust quality management systems, technical excellence, commitment to transparency and customer-centric approach make it a leading global GMP partner for custom buffer solutions and chemical blends.


“We are proud of A&C Bio Buffer’s outstanding reputation for quality and customer service and its emergence as a leading specialty manufacturer of GMP custom buffers and chemical blend products for the biopharmaceutical industry,” said John Godfrey, CEO of A&C Bio Buffer Ltd. “We are delighted that our unique capabilities, European footprint and custom products are being incorporated into Aceto, as we continue our evolution as a dynamic new solutions provider to the global biopharmaceutical sector.”
