Reinhart Partners

What Reinhart Partners does

Reinhart Partners, LLC is a privately held investment management firm headquartered in Mequon, Wisconsin, founded in 1991 and operating as an SEC-registered investment adviser. The firm provides discretionary equity investment management services to institutional clients (pension funds, endowments, foundations) and high net-worth individuals, with all investment activity delivered through a unified Private Market Value (PMV) investment philosophy that targets high-quality, durable business models purchased at discounts to their intrinsic private market value.

The firm operates four distinct equity strategies under the PMV framework: Genesis PMV (small-cap), Mid Cap PMV, Focused PMV, and International PMV, each managed or co-managed by Chief Investment Officer Matthew Martinek and Portfolio Manager Josh Wheeler alongside a team of four analysts and a Head Trader. The investment team of seven is supported by dedicated sales, marketing, and client relations functions. The firm's latest 13F filing (Q1 2026) discloses 77 total equity positions, with concentrated recent activity including material increases in OneSpaWorld, AdaptHealth, and ACI Worldwide, and a complete exit of Marcus & Millichap in Q4 2025. The firm files no patents, holds no certifications beyond standard RIA registration, has no disclosed AI/ML capabilities, and operates from a single domestic office with no international operating footprint.

Reinhart Partners generates revenue through recurring investment management fees charged on client assets managed across the four PMV strategies, distributed through a direct, relationship-based sales model without third-party intermediaries. Pricing is not publicly disclosed and is negotiated bilaterally with each institutional or HNW client. Geographic scope is limited to North America (USA) for operations, though the International PMV strategy invests in non-US equities. The firm is independently owned with no parent company, no institutional investors, and no disclosed funding rounds, with revenue, AUM, and ownership structure not publicly disclosed.

Directly comparable in strategy type (fundamental small/mid value) and client base (institutional + HNW).
