West Pharmaceutical Services Investment Narrative Recap

To own West today, you need to believe in its role as a key supplier of high‑value components for GLP‑1 therapies and biologics, and in management’s ability to keep shifting the mix toward premium products. The latest results and 2026 guidance reinforce that the main near term catalyst remains GLP‑1 and broader HVP demand, while the biggest current risk is execution around product mix, pricing, and the SmartDose divestiture’s impact on margins and revenue consistency.

Among recent announcements, the planned sale of the SmartDose 3.5ml platform to AbbVie, which represented about 4% of 2025 sales, is especially relevant here, since 2026 guidance already bakes this into expected mid single digit organic growth. How effectively West redeploys capacity toward GLP‑1 and higher margin drug handling work will be key to whether the current HVP tailwind translates into sustained earnings quality.

Yet despite the upbeat guidance, investors should still be aware that...

West Pharmaceutical Services' narrative projects $3.6 billion revenue and $675.2 million earnings by 2028. This requires 6.5% yearly revenue growth and a $187.5 million earnings increase from $487.7 million today.
