One Equity Carves Wheeler Fleet from Publicly Traded VSE

February 21, 2025 by John McNulty

One Equity Partners (OEP) has agreed to acquire Wheeler Fleet Solutions from publicly traded VSE Corporation for up to $230 million. The consideration includes $140 million in cash at closing, a $25 million seller note, and up to $65 million in additional contingent consideration.

Wheeler Fleet Solutions is a distributor of aftermarket parts and a provider of engineering services for medium- and heavy-duty fleets. The company offers a broad range of replacement parts, stockroom management and inventory logistics services, and fleet management software.

Wheeler Fleet ships over 3 million line items annually to 700 managed inventory stockrooms and serves thousands of customers nationwide, including commercial and government fleet operators, delivery services, freight carriers, and municipal transportation fleets.

Founded in 1960 as Wheeler Bros., the company is currently led by President Chris Wheeler. It employs more than 300 people and is headquartered southeast of Pittsburgh in Somerset, Pennsylvania, with distribution centers in Pennsylvania, Mississippi, and Texas.

“The Wheeler team looks forward to working with One Equity Partners and executing on our shared vision for Wheeler as an independent business,” said Mr. Wheeler.

“The acquisition of Wheeler Fleet Solutions is the latest example of OEP’s ability to identify valuable industrial service assets from large corporations looking to streamline their operations through divestitures,” said Steve Lunau, a partner at One Equity Partners. “We are committed to building on Wheeler Fleet Solutions’ strong employee and customer-centric culture, while driving continued development and growth.”

VSE Corporation (NASDAQ: VSEC) is a provider of aftermarket distribution and repair services, operating through two segments: aviation and the soon-to-be-divested fleet segment. The aviation segment offers aftermarket parts distribution and maintenance, repair, and overhaul (MRO) services for aircraft components and engine accessories. Founded in 1959, VSE is headquartered near Miami in Miramar, Florida.

In December 2024, VSE acquired Kellstrom Aerospace Group—a distributor of aerospace engine OEM parts, repair management, fleet provisioning, and supply chain management—from AE Industrial Partners at an enterprise valuation of $200 million, consisting of $185 million in cash and $15 million in VSE stock. AE Industrial had acquired Kellstrom in April 2015.

“The sale of our fleet business is the final step in our strategic portfolio transformation, further simplifying and focusing our company, and strengthening our global leadership position as an aviation aftermarket parts and services provider,” said John Cuomo, the president and CEO of VSE.

One Equity Partners is a middle-market private equity firm focused on the industrial, healthcare, and technology sectors in North America and Europe. Its typical equity investments range from $30 million to $300 million.

In April 2022, OEP closed its latest fund, One Equity Partners VIII LP, with committed capital of $2.75 billion. The fund was oversubscribed and closed above its increased hard cap. OEP, which has offices in New York, Chicago, Frankfurt, and Amsterdam, spun out of JP Morgan in 2015 and has completed more than 300 transactions globally since its founding in 2001.

“OEP is excited to partner with the Wheeler Fleet Solutions team as we enter this exciting new chapter together. North America’s truck fleet industry continues to experience steady demand for parts and services, driven by technological advancements and evolving customer needs. With a 65-year legacy of delivering industry-leading quality and service, Wheeler Fleet Solutions is well positioned to accelerate its growth and success as an independent company,” concluded Ori Birnboim, a partner at OEP.

Jefferies served as the financial advisor to VSE Corporation on this transaction.

The acquisition of Wheeler Fleet is expected to close in the second quarter of 2025.

February 21, 2025 by John McNulty

CenterOak Partners has finalized the sale of Shamrock Environmental to Republic Services. This transaction marks the eighth and final portfolio company exit from CenterOak Equity Fund I LP, a 2016 vintage buyout fund.

Shamrock Environmental provides industrial waste and wastewater treatment services, specializing in non-hazardous wastewater treatment, waste collection, and industrial cleaning. The company operates six permitted Centralized Wastewater Treatment (CWT) facilities and several solidification sites.

Shamrock also maintains a fleet of company-owned tankers and vacuum trucks for liquid waste collection and transportation. The company serves commercial and industrial clients across more than 20 states, including businesses in manufacturing, energy, and chemical processing. Founded in 1994, Shamrock is headquartered near Greensboro in Browns Summit, North Carolina, and employs more than 300 people.

CenterOak acquired Shamrock Environmental in January 2020. During its ownership period, the company completed five add-on acquisitions, including three notable deals: Virginia-based Virginia American Industries in December 2020, Virginia-based Environmental Options in June 2023, and Pennsylvania-based JG Environmental in February 2024.

“Alongside management, CenterOak built a scaled provider of wastewater and waste processing services covering growing markets located on the East Coast from Florida to Pennsylvania,” said Jason Sutherland, a managing partner at CenterOak. “Over five years working with the company, revenue and EBITDA grew significantly due to investments that more than quadrupled permitted capacity to provide non-discretionary, mission-critical services.”

Republic Services (NYSE: RSG) is a waste management and environmental services company serving residential, commercial, industrial, and municipal customers across the United States. The company also offers landfill operations, transfer stations, and energy recovery services. Republic Services operates in 41 states and Puerto Rico, with more than 350 collection operations, 200 transfer stations, 190 active landfills, and 90 recycling centers. Founded in 1998 by Wayne Huizenga, the company is headquartered in Phoenix, Arizona.

According to Republic Services CEO Jon Vander Ark, the company spent $358 million on acquisitions in 2024 and plans to invest $1 billion in acquisitions in 2025, with the purchase of Shamrock Environmental as its first transaction of the year.

Headquartered in Dallas, CenterOak makes equity investments ranging from $20 million to $150 million in companies with enterprise values between $50 million and $500 million and EBITDA between $5 million and $35 million. The firm focuses on sectors including business services, industrial services, and consumer services.

In August 2024, CenterOak completed the final close of CenterOak Equity Fund III LP at its $1.1 billion hard cap. The firm’s second fund closed at its $690 million hard cap in April 2021, while its first fund closed in 2016 with $420 million of capital.

Houlihan Lokey acted as the lead financial advisor to Shamrock Environmental on this transaction, with Brown Gibbons Lang serving as co-advisor.

Premium Environmental Services (PES) specializes in spill response and waste disposal, offering nationwide emergency response coverage through its contractor network. The company is headquartered near Evansville in Newburgh, Indiana.

Headquartered near Los Angeles in Pomona, California, Worldwide Recovery Systems provides waste collection, transportation, and disposal services across California and Arizona.

Its sister company, YES Management, operates a non-hazardous waste transfer station in Yuma, Arizona.

“The acquisitions of PES and WRS each have tremendous potential to advance our strategic priorities with increased access to the eastern and western U.S. markets,” said Brian Recatto, the president and CEO of Crystal Clean. “Targeted investments in vertical integration are a core component of our strategy, and we are thrilled to welcome the PES and WRS teams into Crystal Clean.”

J.F. Lehman acquired publicly traded Crystal Clean (formerly Heritage-Crystal Clean) for $1.2 billion in cash in October 2023 [J.F. Lehman is Crystal Clear on Crystal Clean’s Future]. At the time of the acquisition, the valuation reflected 7.7x the company’s trailing twelve months adjusted EBITDA of $156 million.

In December 2024, J.F. Lehman closed its latest flagship fund, JFL Equity Investors VI LP, securing $2.2 billion in capital. The fund is the largest in the firm’s history and significantly exceeded its original target of $1.6 billion. Founded in 1992 by Dr. John Lehman, who served six years as Secretary of the United States Navy, the firm is headquartered in New York City, with an additional office in Washington, DC.
