GSO Capital Partners

GSO Capital Partners was an American alternative investment manager that became Blackstone's dedicated credit investment platform. The firm was established in 2005 by Bennett Jay Goodman, J. Albert Smith III, also known as Tripp Smith, and Doug Ostrover. The three founders had previously worked together in the leveraged-finance businesses of Donaldson, Lufkin & Jenrette and Credit Suisse First Boston. Their experience in arranging, underwriting, and investing in leveraged loans provided the foundation for GSO's focus on credit markets rather than traditional public-equity investing. GSO operated across several segments of the alternative-credit market. Its activities included collateralized loan obligation vehicles investing in senior secured loans, hedge funds pursuing special situations and event-driven credit opportunities, mezzanine-debt funds, and private-equity-style funds designed to provide rescue financing to companies facing liquidity pressure or difficult capital structures. The platform also participated in leveraged buyouts, mergers and acquisitions, leveraged recapitalizations, and growth financing. Its investment toolkit could include senior loans, high-yield bonds, distressed securities, second-lien loans, mezzanine instruments, equity securities, and credit derivatives. The business initially developed independently but attracted institutional backing as demand for leveraged-finance exposure expanded. In May 2007, GSO sold a minority interest to Merrill Lynch. Blackstone had already been an original investor in GSO funds and acquired the firm in March 2008 for approximately $1 billion. The reported consideration included $620 million in cash and stock, together with an earnout of up to $310 million payable over the following five years if specified earnings targets were met. Blackstone combined GSO's operations with its existing debt-investment activities, creating one of the largest credit platforms in the alternative-asset-management industry at that time, with more than $21 billion in assets under management according to contemporary reporting. Following the acquisition, GSO expanded both its fund-raising and its European capabilities. The Blackstone/GSO Capital Solutions Fund closed in July 2010 with more than $3.25 billion in commitments. In 2010, the platform also acquired $3.1 billion of collateralized loan obligations from Callidus Capital Management. In March 2011, it acquired European CLO manager AIB Capital Markets, including four CLO vehicles with a combined value of more than €1.5 billion. GSO subsequently raised substantial capital for mezzanine strategies, including more than $2 billion for a fund reported in 2011 and $4 billion for a second middle-market mezzanine fund in 2012. GSO's investment and trading activities occasionally placed it in contentious situations. One notable episode involved credit protection accumulated on homebuilder Hovnanian Enterprises before a proposed debt refinancing. In 2018, a federal judge rejected Solus Alternative Asset Management's request to halt the debt exchange, finding that Solus had not provided sufficient evidence of irreparable harm to it or the market. The dispute illustrated the legal and strategic complexity of credit investments involving distressed or highly leveraged issuers. On November 9, 2020, Blackstone rebranded GSO as Blackstone Credit. The change ended GSO's operation as a distinct public-facing brand, although its investment capabilities and personnel were incorporated into Blackstone's broader credit organization. The historical GSO name therefore refers to a predecessor credit platform rather than a currently separate asset manager.

GSO Capital Partners was founded in 2005 by Bennett Jay Goodman, J. Albert Smith III, known as Tripp Smith, and Doug Ostrover. The founders had worked together in leveraged finance at Donaldson, Lufkin & Jenrette and subsequently at Credit Suisse First Boston after Credit Suisse acquired DLJ. They established GSO to invest across credit markets and to apply their leveraged-finance expertise through funds and other institutional vehicles. The firm's strategy set included senior secured and leveraged loans, high-yield debt, distressed securities, special-situations investments, mezzanine finance, collateralized loan obligations, and rescue capital. Its special-situations funds could invest across the capital structure, including loans, bonds, second-lien debt, equity, and credit derivatives. Its mezzanine and capital-solutions vehicles supplied financing for leveraged buyouts, acquisitions, recapitalizations, growth initiatives, and companies experiencing liquidity or capital-structure problems. GSO sold a minority stake to Merrill Lynch in May 2007. In March 2008, Blackstone acquired the firm for approximately $1 billion. The reported transaction consisted of $620 million in cash and stock, plus an earnout of as much as $310 million over five years subject to earnings targets. Blackstone had been an original investor in GSO funds and integrated GSO with its existing debt-investment operations. The combination produced a credit platform with more than $21 billion in assets under management according to reporting at the time. The combined organization continued to grow through fund launches and acquisitions. In July 2010, the Blackstone/GSO Capital Solutions Fund completed its final closing with commitments exceeding $3.25 billion. During 2010, GSO acquired $3.1 billion of CLOs from Callidus Capital Management. In March 2011, it acquired European CLO manager AIB Capital Markets and four related CLO vehicles valued at more than €1.5 billion. The firm also raised large mezzanine vehicles, including more than $2 billion reported for a fund in 2011 and $4 billion for a second middle-market mezzanine fund in 2012. A significant dispute arose from GSO's credit protection position involving Hovnanian Enterprises. GSO accumulated approximately $330 million of credit protection on the homebuilder in 2017 before a proposed refinancing and debt exchange. Solus Alternative Asset Management challenged the transaction and sought a temporary injunction. In January 2018, a federal judge denied Solus's request, concluding that the evidence presented did not establish irreparable harm to Solus or the market. The episode became a notable example of litigation surrounding distressed-credit transactions and the strategic use of credit derivatives. On November 9, 2020, Blackstone announced the rebranding of GSO as Blackstone Credit. The change consolidated the platform under Blackstone's corporate identity and ended GSO's existence as a separate brand. Its historical activities remain relevant to the development of Blackstone's broader credit business, but GSO Capital Partners should be treated as a former name and predecessor platform rather than an active independent firm.

Institutional alternative-credit platform focused on leveraged finance, private credit, distressed and special-situations investing, mezzanine finance, and rescue capital.

• Collateralized Loan Obligation VehiclesStructured credit

  GSO sponsored and managed CLO vehicles that invested primarily in pools of secured leveraged loans. The strategy provided institutional investors with structured exposure to corporate credit while giving GSO a scalable channel for deploying capital in the leveraged-loan market. Its CLO activity expanded through acquisitions of existing portfolios and managers in the United States and Europe.

• Special Situations Hedge FundsAlternative credit

  These funds pursued long/short credit, event-driven, distressed, and other special-situations opportunities. Investments could span senior secured loans, high-yield bonds, distressed securities, second-lien loans, mezzanine debt, equity securities, and credit derivatives. The broad mandate allowed the platform to invest across a company's capital structure when market stress or corporate events created mispricing.

• Capital Opportunities FundsMezzanine finance

  GSO's Capital Opportunities Funds supplied mezzanine capital to middle-market and other companies. The funds supported leveraged buyouts, mergers and acquisitions, leveraged recapitalizations, and growth financing. Mezzanine instruments generally occupied a position between senior secured debt and common equity, allowing GSO to seek enhanced returns while providing borrowers with flexible capital.

• Capital Solutions FundsRescue financing2010

  The Capital Solutions platform provided private equity and credit capital to companies needing liquidity or facing challenges in their existing capital structures. It was designed for situations where conventional financing was unavailable or insufficient, including stressed balance sheets, refinancing needs, and complex recapitalizations. The Blackstone/GSO Capital Solutions Fund closed in 2010 with more than $3.25 billion in commitments.

• Leveraged Finance InvestmentsCorporate credit

  GSO invested in and provided senior secured loans to middle-market and leveraged companies through CLOs, investment funds, separately managed accounts, and related pools of capital. This business formed the core of the firm's participation in the leveraged-finance marketplace and complemented its higher-risk mezzanine, distressed, and rescue-financing strategies.
