Merck concludes USD 10 billion acquisition of Verona Pharma

Through this acquisition Merck has added Ohtuvayre (ensifentrine), a first-in-class selective dual inhibitor of phosphodiesterase 3 and 4 (PDE3 and PDE4), to its growing cardio-pulmonary pipeline and portfolio. The U.S. Food and Drug Administration approved Ohtuvayre in June 2024 for the maintenance treatment of chronic obstructive pulmonary disease (COPD) in adult patients. Ohtuvayre is a novel inhaled mechanism for the maintenance treatment of COPD in more than 20 years and combines bronchodilator and non-steroidal anti-inflammatory effects. Ohtuvayre is also being evaluated in clinical trials for the treatment of non-cystic fibrosis bronchiectasis.

Under the terms of the acquisition agreement, Merck, through a subsidiary, has acquired all outstanding shares of Verona Pharma for $107 per ADS, each of which represents eight Verona Pharma ordinary shares, for a total transaction value of approximately $10 billion.

As previously disclosed, the acquisition will result in the capitalization of most of the purchase price as an intangible asset for Ohtuvayre (which will be amortized as a GAAP-only charge over the life of the product). The transaction is expected to negatively impact non-GAAP EPS by approximately $0.16 in the first 12 months, representing costs associated with financing the transaction partially offset by Ohtuvayre performance.
