On July 10, 2025, the following communication was sent to certain clinical trial sites:

Dear Healthcare Provider,

Yesterday, it was announced that Verona Pharma is to be acquired by Merck. Please see the full press release with the announcement following this link: https://www.veronapharma.com/news/merck-to-acquire-verona-pharma-expanding-its-portfolio-to-include-ohtuvayre-ensifentrine-a-first-in-class-
copd-maintenance-treatment-for-adults-and-expected-to-drive-growth-into-the-next-dec/

Ensifentrine’s unique combination of bronchodilatory and non-steroidal anti-inflammatory effects fits well with Merck’s commitment to delivering innovative treatments to patients and their ability to execute on our science-led programs.

This acquisition is not expected to impact planned or ongoing trials, which we will continue to conduct “business as usual” with PPDs support.

Sincerely,

Verona Pharma Clinical Team
