Improving quarterly trends exiting 2025 and a baseline of modest operational growth excluding divestitures support a narrative of stabilization.

Strong Market Position & Advantage: Scale and global reach are repeatedly highlighted as a stabilizing advantage, with broad geographic coverage and a large portfolio supporting access, supply reach, and competitive standing in off-patent medicines. The strategic shift toward complex generics and specialty brands is framed as reinforcing the company’s long-term positioning against pricing pressures.
