Credits Covered


We invest in public and private corporate credit instruments across multiple strategies.


GSO’s team has a deep reservoir of credit and industry expertise across the entire range of market cycles. Our senior investment professionals have an average of 21 years of industry experience.


Scale allows us to provide financing solutions that enhance a corporation’s financial flexibility, while capturing opportunities our investors might have otherwise missed. Our capital has enabled strong companies to expand and troubled companies to remain viable.


The solutions we offer are not often available elsewhere in the credit markets. Their breadth is our competitive advantage – drawing upon a wide range of disciplines, including loans, high yield and investment grade bonds, structured credit, mezzanine lending and rescue financing.

Our Strategies

Our activities range from investing in public debt that offers attractive risk-adjusted returns to providing private capital to companies. This allows us to maximize potential in various market conditions, and in times of both stability and volatility.

GSO’s U.S. and European loan, high yield and investment grade bond strategies rely on bottom-up fundamental analysis and investing discipline. Given our scale as one of the largest CLO managers in the world, we are also able to source differentiated investments and commit capital in size.

GSO has a dedicated global CLO investing team that utilizes both proprietary technology and the expertise of GSO’s large credit research team to invest in primary and secondary CLO opportunities. The team evaluates all parts of the CLO capital structure, from investment grade notes to equity, across many different managers in the U.S. and Europe to seek the best risk adjusted returns for investors.

GSO provides privately originated, senior secured, floating rate loans to U.S. and European middle market companies. We partner with these firms and their sponsors to understand their businesses, address their challenges and support their long-term strategies.
GSO’s mezzanine business has a flexible mandate that provides privately negotiated capital to companies in connection with leveraged buyouts, acquisitions, recapitalizations and growth financings. Our expertise in these areas helps companies navigate change while generating attractive returns for our investors.
Deep industry expertise underpins our energy business, which provides capital solutions for performing and distressed energy companies. By operating across the capital structure, we can respond quickly and creatively to companies’ needs.

Our Portfolio

We seek to make companies stronger by providing capital when other funding is unavailable or where our expertise and scale enable uniquely flexible capital solutions.


GSO supported the public-to-private takeover of Laird plc, an industrial business headquartered in the U.K. Laird designs, manufactures and assembles products that protect electronics from electromagnetic interference and heat, and enable connectivity in wireless applications and antenna systems. The company maintains leading market positions in each high-margin, niche electronics business in which it operates. GSO’s ability to work quickly to negotiate, document and put in place a flexible structure enabled the timely execution of this 2018 transaction.


Diebold Nixdorf is an end-to-end provider of services, software and hardware for ATMs and electronic point-of-sale systems in the financial and retail industries. Diebold manages over two million ATMs and electronic point-of-sale systems in 130 countries across EMEA, the Americas and Asia Pacific. Under a compressed timeline, GSO was able to leverage its previous investments in the space and its strong industry relationships to provide a partial backstop and make a large investment in Diebold in 2018.

Altus Power America

GSO led an $850 million recapitalization in early 2020 of Altus Power, a market-leading solar power company that provides clean electricity to clients across the United States. The recapitalization included one of the first privately rated investment-grade financings comprised solely of commercial and industrial scale distributed solar assets. Our partnership with Altus will enable the company to meet growing demand for low-cost, renewable energy in North America.
