North Run Capital

The firm pursues a concentrated, value-oriented strategy focused on small- and mid-cap public equities. It is particularly known for its event-driven approach and active participation in PIPE (Private Investment in Public Equity) transactions. The team looks for mispriced companies where a specific catalyst—such as a restructuring, new product cycle, or management change—is expected to surface value.

Thomas B. Ellis serves as the Portfolio Manager and is the central decision-maker for the firm's investments. He is supported by a lean team that includes analyst Patrick J. Burke, among others. The concentrated portfolio reflects Ellis's deep involvement in sourcing, research, and ongoing monitoring of positions.

While not a traditional activist in the sense of launching public proxy campaigns, the firm's strategy often involves taking concentrated stakes and engaging directly with management. Its participation in PIPE financings and event-driven situations frequently implies a constructive dialogue with company leadership to help unlock value. SEC filings have shown the firm with ownership stakes above 5% in certain holdings, a threshold that often accompanies active engagement.

Deal flow is primarily sourced through the firm's established network of relationships with investment banks, placement agents, and corporate management teams. Given its long tenure in the small-cap space and its reputation for providing growth capital, North Run is often approached directly by companies seeking a reliable institutional partner for private placements. The firm's generalist mandate also allows it to look broadly across sectors for mispriced opportunities.

North Run Capital was originally organized around a flagship limited partnership that was discontinued in 2009. The firm continued to operate as an SEC-registered investment adviser, managing capital through separately managed accounts or other private structures. This transition to a leaner operating model reflects a focus on investment performance over asset gathering, typical of small, concentrated hedge fund managers.
