ClearBridge Energy Midstream Opportunity Fund Inc.

Incorporated in Maryland and headquartered in New York, this closed-end equity mutual fund is launched and managed by Legg Mason Partners Fund Advisor, LLC, with co-management by ClearBridge Investments, LLC. The fund operates as a pooled investment vehicle registered on the NYSE, focusing exclusively on U.S. public equity markets within the energy sector.

The fund's investment strategy concentrates on master limited partnerships (MLPs) engaged in infrastructure operations for crude oil, natural gas liquids, and refined products. Its portfolio selection criteria emphasize companies characterized by long-lived tangible assets, predictable cash flow generation, and limited direct exposure to commodity price fluctuations. This approach targets the midstream energy infrastructure segment, which typically encompasses transportation, storage, and distribution assets.

As a closed-end fund structure, the vehicle generates revenue primarily through management fees charged to shareholders based on assets under management. The fund was established in April 2011 and maintains a market capitalization of approximately $1.0 billion. As an investment fund rather than an operating company, it does not maintain traditional employee counts or revenue streams comparable to operating businesses; instead, its scale is measured by assets managed and investor base size.
