Works at the intersection of strategy and finance with high tech, industrial, and pharmaceutical clients to identify and prioritize corporate strategies for restructuring, performance improvement, and growth


Werner is a corporate-finance expert and one of the leaders of the Strategy Analytics Center, McKinsey’s center of competence for financial and capital-markets analysis, M&A, and valuation. He also leads the firm’s work in investor relations and investor communications.

Werner advises teams and clients on in-depth financial analyses, corporate and business-unit valuation, M&A, capital structure, dividend policy, investor relations, and capital-market diagnostics to identify, value, and prioritize corporate strategies. He works across all industries and has deep experience in the high-tech, industrial, transportation, and pharmaceutical sectors.

Examples of Werner’s recent client work include a portfolio review for a high-tech company that resulted in the divestiture of a business unit and significant change in the capital-investment policy, preparation of an investor day for the new CEO of a European client, M&A-target screening for an industrial company seeking growth outside the core, and a postmerger integration project for a software company.

Beyond Werner’s direct client work, he leads many of McKinsey’s corporate-finance trainings. He has written extensively on value creation, investor relations, and M&A; is a member of the editorial board for McKinsey on Finance, the firm’s quarterly publication on corporate-finance topics; and occasionally hosts the Strategy & Corporate Finance Practice’s podcast.

Born and raised in Germany, Werner has worked in several McKinsey offices, including in Berlin, Boston, Frankfurt, and New York, throughout his career.
