This paper analyzes the persistence of a blockholder public company in an asset class commonly associated with private ownership. Westshore Terminals, a single-asset coal export terminal operating under long-term lease constraints, has remained publicly listed for approximately two decades despite structural forces that might predict privatization or integration. The paper interprets this outcome through an institutional regime-choice framework grounded in Coase’s theory of firm boundaries, North’s conception of institutions as rule systems, Hayek’s account of dispersed knowledge, Acemoglu’s analysis of institutional persistence, and Jensen and Meckling’s principal–agent model. Using publicly disclosed ownership and governance documents, the analysis identifies a configuration characterized by concentrated beneficial ownership, formalized management and governance agreements, and operation within a securities-law disclosure regime. The public institutional framework imposes transparency and minority shareholder protections while permitting concentrated influence. The paper develops a simple formal extension of principal–agent theory in which a blockholder chooses between public and private regimes, and shows that public listing can constitute a stable equilibrium when disclosure and liquidity benefits offset regime costs. The central claim is not that the public form is structurally inevitable, nor that specific motives can be inferred, but that the observed configuration is consistent with agency operating within institutional constraint. The case illustrates how public listing can function as a governance technology in blockholder capitalism and contributes to the comparative study of infrastructure ownership and institutional regime choice.

Why is this company public? Westshore Terminals is a single coal export terminal that many observers might expect to be privately owned. Similar infrastructure assets are often held by pension funds, infrastructure funds, or integrated into larger commodity firms. Yet Westshore has remained publicly listed for roughly twenty years. This paper argues that the answer lies not in structural inevitability but in institutional compatibility. Public documents show that ownership is concentrated in a large blockholder and that governance operates through formal management and appointment agreements within a securities-law disclosure regime. The public company structure imposes transparency and minority shareholder protections, while still allowing concentrated influence. The paper shows that this configuration can be stable. Public listing may function as a governance framework that reduces certain agency problems, distributes information, and preserves liquidity—while remaining consistent with blockholder control. The case suggests that infrastructure ownership structures are not determined solely by market forces. They also reflect institutional design and individual agency operating within formal rules.
