Sterling Investment Partners Secures $1.6 Billion for Strategic Growth in Business Services

Sterling Investment Partners, a notable private equity firm based in Greenwich, Connecticut, has reached a significant milestone by closing its fifth institutional fund, Sterling Investment Partners V, L.P. This fund, which has successfully capped at $1.6 billion, surpasses its initial target of $1.25 billion and reflects a robust commitment from both institutional investors and Sterling employees. The swift closure of Fund V, just months following its launch, underscores the firm’s credibility and strategic appeal in the middle-market investment landscape.

With a clear focus on control equity investments primarily in the business services and distribution sectors, Sterling aims to leverage its operationally intensive approach to foster deep partnerships with business founders and leaders. This strategic direction positions the firm to capitalize on opportunities within these sectors, particularly as businesses seek resilient growth in a changing economic environment. The firm’s experienced leadership team, including Co-Founder and Managing Partner Charles Santoro, expresses optimism about the fund’s potential, highlighting their commitment to delivering value to limited partners through targeted investments and active management.

The inaugural investment from Fund V is a notable one, as it involves XKIG, a previous portfolio company, through a managed continuation vehicle that also attracted significant oversubscription. This strategic move illustrates Sterling's intent to reinforce its existing partnerships while exploring new avenues for growth within its portfolio. Senior Managing Director Ruth Lane attributes the enthusiastic response to Fund V to the firm's dedicated team and successful track record in forming global partnerships. With over three decades of experience in acquiring middle-market companies that exhibit sustainable competitive advantages, Sterling is well-positioned to navigate the complexities of the investment landscape.

In addition to the successful launch of Fund V, Sterling Investment Partners collaborates with Eaton Partners, a Stifel Company, as the lead placement agent, while Piper Sandler & Co. provides advisory services. Legal counsel for the fund is managed by Kirkland & Ellis, ensuring that Sterling maintains a comprehensive support network as it embarks on its investment journey. This collaborative approach not only strengthens the firm's operational capabilities but also enhances its strategic outreach in the market.

The successful closure of Fund V marks a pivotal moment for Sterling Investment Partners as it continues to solidify its role in the private equity sector, demonstrating strong investor confidence and a commitment to strategic growth initiatives.
