Stadium Capital Management

Alexander Medina Seaver has led investment decisions since founding the firm in 1999. As Managing Partner and Portfolio Manager, he runs the concentrated portfolio alongside Managing Director Bradley Shisler, operating with a lean team structured to ensure singular accountability on position sizing and engagement strategy.

Stadium runs a highly concentrated long-only equity portfolio that typically holds fewer than 15 names. This concentration is intentional — the firm believes meaningful excess return comes from deep knowledge of a limited number of businesses, not from diversification that dilutes conviction or management access.

Yes. The firm's most prominent activist intervention was at PetSmart in 2014, where it waged a public proxy fight to force a sale of the company. The campaign succeeded: PetSmart was acquired by a consortium led by BC Partners for $8.7 billion later that year (per public record, 2014).

Yes, Stadium is a registered investment adviser that manages capital for institutional and high-net-worth clients. However, it has historically operated as a capacity-constrained manager, closing its strategy to new investors when further growth would compromise the concentrated mandate.

The firm focuses primarily on consumer discretionary, consumer staples, and select industrial companies. Within these sectors, it targets businesses with durable competitive positions, high insider ownership, and balance sheets that allow for long-term strategic patience.

Stadium relies on bottom-up fundamental research rather than top-down macro screening. The small team cultivates deep relationships with management teams and industry operators, generating ideas through proprietary networks rather than traditional sell-side coverage or screen-based sourcing.

Technically, Stadium is an asset manager open to external clients, but it operates with a family-office posture — concentrated positions held for a decade or longer, a refusal to scale, and a willingness to engage publicly when governance change is required. This hybrid behavior distinguishes it from both pure family offices and broad-based mutual fund complexes.
