Case Study: a midsize public pharmaceutical company achieves a smooth post-merger integration with L.E.K. Consulting

a midsize public pharmaceutical company completes Day 1 integration in 36 hours with L.E.K. Consulting

The vendor L.E.K. Consulting was retained by a midsize public pharmaceutical company to support the post-merger integration following its accelerated acquisition of an Ireland-based counterpart. The challenge was to combine the two companies without disrupting business, maintaining strict FDA and SEC compliance, while also redesigning the sales force, transitioning IT systems within 72 hours, and establishing a platform for future growth.

L.E.K. Consulting mobilized and led an integration management team, creating detailed plans for 16 functional areas and providing dedicated support. The solution ensured a smooth Day 1 with no supply interruptions, protected revenues, and a full IT migration within 36 hours. As a result, L.E.K. helped the client maintain business continuity and commercial stability, successfully transitioning the integration ownership back to the client to focus on future growth opportunities.
