Overview

Katie Lencioni is a litigation partner in the Chicago office of Kirkland & Ellis LLP. Katie is a trial lawyer with a broad commercial litigation practice encompassing M&A disputes, employment and restrictive covenant matters, contract issues, antitrust and competition actions, product liability cases and other complex disputes across a wide array of industries including finance, travel, aviation, automotive, pharmaceutical and healthcare.

Recognized by Best Lawyers since 2024 for her commercial litigation practice, Katie has litigated matters at both the trial and appellate levels in state and federal courts, as well as in arbitration and mediation. She served as trial counsel in a high-profile product liability case for 3M, which resulted in a unanimous defense verdict following a two-week jury trial and earned her recognition as a runner-up for The American Lawyer’s “Litigator of the Week.” She likewise served as trial counsel in a five-week jury trial for Abbott involving infant formula, which resulted in a unanimous defense verdict on all claims and recognition of the trial team as “Litigator of the Week” by The American Lawyer Litigation Daily. Her trial work also includes significant public and confidential breach of contract matters nationwide, in which she secured favorable outcomes.

Katie has led numerous post-M&A disputes, including purchase price adjustments, earn-out and valuation disputes, employment and shareholder claims, and fraud matters, representing hedge funds, private equity sponsors and portfolio companies. Her clients include 3i, Citadel, GTCR, Summit Partners, Blackstone, Alpine Investors, TPG, TCV, Levine Leichtman Capital Partners, Kingswood Capital Management, Staple Street Capital and Waud Capital, among others. She regularly advises clients in pre-litigation and litigation matters involving deferred compensation, restrictive covenants, trade secrets, board and shareholder disputes, and third-party subpoenas.

In addition, Katie maintains an active antitrust practice. She has represented Eli Lilly, the Blue Cross Blue Shield Association and multiple Blue Plans in federal antitrust matters, multidistrict litigations and class actions. She also serves as outside antitrust counsel to a large eye care insurer and a well-known film distributor.

Katie was named Pro Bono Partner of the Year for her federal habeas work overturning the wrongful conviction of a man sentenced to 100 years in prison for first-degree murder, and she received a “Litigator of the Week” recognition from The American Lawyer Litigation Daily for that work.

Katie is actively involved in the Firm’s recruiting, mentoring, associate training, inclusion initiatives and Women’s Professional Network, where she previously served as co-chair.
