- Merck’s flagship cancer immunotherapy, Keytruda, faces patent expiration starting in 2028.
- Verona Pharma specializes in therapies for chronic respiratory conditions, including Ohtuvayre for COPD.

- Merck’s shares have declined over 18% this year, emphasizing the strategic importance of such acquisitions.
Strategic Imperatives Driving Merck’s Expansion
Merck’s aggressive pursuit of Verona Pharma is a direct response to the approaching patent cliff for its flagship cancer immunotherapy, Keytruda. Keytruda generated nearly $30 billion in sales during 2024, but its patent protection is set to diminish starting in 2028, presenting a substantial challenge to Merck’s revenue outlook.
Consequently, Merck has initiated a series of strategic maneuvers designed to mitigate potential revenue erosion and foster new growth vectors. These include recent discussions to acquire Swiss biotech MoonLake Immunotherapeutics for over $3 billion, alongside a $2 billion licensing agreement for a heart disease drug with Jiangsu Hengrui Pharmaceuticals. The acquisition of Verona Pharma aligns with this broader strategy of broadening its therapeutic portfolio and securing long-term financial stability.
Verona Pharma’s Specialized Portfolio
Verona Pharma specializes in the development of therapies for chronic respiratory conditions, an area of significant unmet medical need. Its primary commercial asset, Ohtuvayre, is a treatment specifically for Chronic Obstructive Pulmonary Disease (COPD), a widespread and debilitating lung condition affecting millions globally. This targeted focus on a specialized disease area aligns precisely with Merck’s stated objective of expanding its presence in such high-value therapeutic segments.
Financial Context of the Acquisition
Financially, the proposed $107 per share offer represents a notable premium over Verona’s Tuesday closing price of $86.9. This previous valuation gave the company a market capitalization of approximately $7.39 billion, according to LSEG data. Verona reported total net revenue of $76.3 million in the first quarter of 2025, underscoring its emerging commercial potential.
For Merck, a pharmaceutical giant valued at over $204 billion, strategic acquisitions like Verona Pharma are critical. Despite its substantial market presence, Merck has seen its shares decline over 18% this year, emphasizing the strategic importance of such transactions for its long-term financial health and growth trajectory in a competitive pharmaceutical landscape.
