Angeles Equity Gets Busy with Critical Environment Cleaning Platform

June 13, 2023 by John McNulty

Data Clean Corporation, a provider of critical environment cleaning, contamination control, and remediation services, has acquired SML Enterprises.

Data Clean’s services include exterior hardware cleaning, top-of-floor cleaning, and underfloor plenum cleaning. Combinations of these services are performed by the company at scheduled intervals, ranging from once per year to once a day. Within a data center, a plenum refers to the area above the suspended ceiling or under the raised floor that is used for the circulation of air. It acts as a pathway for distributing cool air from the cooling systems to the server racks and other equipment in the data center.

Data Clean provides its services to thousands of facilities around the world including data centers, computer rooms, network and telecommunications facilities (through its “Data Clean” branded division) and biopharmaceutical and life sciences cleanrooms and laboratories (through its “Sterile Science” branded division).

The company’s Sterile Science division provides sanitization services (reduces contamination by 99.9% or 3-log), disinfection services (eliminates between 99.99% and 99.999% of all contaminates), and sterilization services (eliminates 99.9999% of all organisms, known as a 6-log). The division’s customers include operators of pharmaceutical suites, cleanrooms, healthcare facilities, critical production and laboratory areas.

Data Clean operates full-service branches in Canada, Hong Kong, India, Mexico, Saudi Arabia, Singapore, United Arab Emirates and the United States. The company was founded in 1979 and is headquartered near Chicago in Des Plaines, Illinois

SML Enterprises is a provider of environmental contamination control services to data centers and cleanrooms. The company was founded in 1984 and is headquartered near Washington DC in Bristow, Virginia.

Post-closing, SML Executive Vice President Mike Piscelli will transition to an advisory role and continue to support the growth of the combined business. “When our family decided that the time was right to sell our company, we quickly turned to Data Clean due to our longstanding relationship, shared dedication to growth, focus on quality, and most importantly, our commitment to employees and clients,” said Mr. Piscelli. “Being what we view as the leader in critical environment contamination control, Data Clean was our clear choice as an acquisition partner.”

The buy of SML Enterprises is the first add-on acquisition for Data Clean since being acquired by Angeles Equity in November 2022. At that time, the firm partnered with the company’s owners – Richard Hill and Dean Sirakides – to execute a buy-and-build strategy in the critical environment contamination control sector.

“The strategic fit between Data Clean and SML is ideal and a great first step towards executing our strategy of further consolidating the critical environment contamination control space,” said Frank Spelman, managing director at Angeles. “As the data center sector continues to grow, the essential nature of keeping those facilities free from contaminants will only increase. Angeles is optimistic about the long-term outlook for this sector.”

“SML is a great fit for us, given the strong alignment of their culture of excellence with Data Clean’s prioritization of its people and clients. We believe the combination of our decades of collective experience with the latest technological innovations will provide our customers with the peace of mind that comes from best-in-class solutions,” said Mr. Hill. “This add-on acquisition highlights our commitment to being recognized as the market leader in contamination control services for critical environments.”

Los Angeles-based Angeles Equity makes control investments in companies with enterprise values up to $200 million that have headquarters and primary operations in the United States and Canada. Sectors of interest include aerospace, automotive, building products, capital goods, chemicals, electronics, manufacturing, metals, transportation and logistics, packaging, and distribution.

June 13, 2023 by John McNulty

Allentown, a portfolio company of Aterian Investment Partners, has acquired Northwestern Systems Corporation (DBA BetterBuilt). The buy of BetterBuilt is the first add-on acquisition for Allentown since being acquired by Aterian in April 2022 from Heartwood Partners.

Allentown is a provider of lab equipment used in the life sciences sector. The company’s products include reusable and single-use housing equipment for rodents, primates, rabbits, guinea pigs and poultry; biological safety cabinets; cabinet washing and sterilization; and monitoring and animal census systems.

Allentown’s customers include academic research institutions, pharmaceutical and biotechnology companies, private laboratories, governmental research institutions, and contract research organizations. The company, led by CEO John Coiro, was founded in 1968 by the Coiro family and is headquartered in Allentown, New Jersey.

These systems – which include a combination of cage and rack washers, bottle and accessory washers, automatic detergent and disinfectant dispensers, water filtration systems, and monitoring and control features – are designed to provide effective cleaning while minimizing the risk of cross-contamination between animals.

BetterBuilt, the largest independent North American vivarium washing equipment manufacturer, is led by President and co-owner Harry Lim and is headquartered near Vancouver in Delta, British Columbia.

“This partnership will continue the vision of BetterBuilt that we have built over many years,” said Mr. Lim. “It is clear that both BetterBuilt and Allentown have continuously developed and refined through the years a strong culture of producing state-of-the-art products for our customers. We are confident we have found the right partner to help us in our next stage of growth.”

“The acquisition of BetterBuilt represents an important milestone for Allentown,” said Brandon Bethea, a co-founder and partner at Aterian. “By adding BetterBuilt’s highly engineered products and the company’s talented team, Allentown offers a more fulsome suite of lab housing, washing and sterilization solutions aimed at solving some of the most difficult aspects of managing a vivarium. We would like to congratulate the BetterBuilt team for building a special business and we couldn’t be more enthusiastic about the opportunity together.”

“We could not be more excited to partner with BetterBuilt and look forward to welcoming the team to the Allentown family,” said Mr. Coiro. “We are strong believers in BetterBuilt’s technology and look forward to working with the team to continue its momentum. With our partnership, Allentown and BetterBuilt will be better positioned to serve our overlapping and complementary customer bases by providing our customers with a one-stop solution to address their vivarium needs.

“Allentown’s partnership with BetterBuilt will expand our addressable market and establish Allentown as a proven acquisition platform as we transform Allentown into a broader solutions provider in the life sciences market,” said Daniel Phan, a managing director at Aterian. “We look forward to working on post-close initiatives across the combined company.”

Aterian invests from $10 million to $100 million in middle market businesses with $50 million to $750 million in revenue and $10 million to $50 million in EBITDA. The firm’s latest fund, Aterian Investment Partners IV LP, closed in October 2021 with $830 million of committed capital. Aterian has offices in New York City and Coral Gables, Florida.

“DC Kilowatts is known for providing excellent service to its customers and we are pleased to welcome them to the Exponential Power family,” said Mr. Walker. “Bill Fink and his team built an impressive company with a 43-year history and have been a Crown Battery authorized representative since 2007. Their motive power expertise is a great fit for Exponential Power, expanding our geographic footprint, strengthening our more-than-30-year relationship with Crown Battery, and further increasing our sales and service capabilities.” Ohio-based Crown Battery specializes in manufacturing deep-cycle batteries used in industrial equipment, golf carts, marine applications, and floor-cleaning machines.

Exponential Power was formed in January 2021 through the merger of Storage Battery Systems (acquired by High Road in May 2017), Nolan Power Group (July 2018), Quality Standby Services (July 2019) and Summit Power Systems (October 2019).

The buy of DC Kilowatts is Exponential Power’s sixth acquisition in the past 18 months.

Chicago-based Twin Brook focuses on loans to private equity-owned companies with EBITDA between $3 million and $50 million, with an emphasis on companies with $25 million of EBITDA and below. The firm targets senior financing opportunities up to $200 million, with hold sizes across the platform ranging from $25 million up to $150 million. Twin Brook’s products include opportunistic investments in second lien, mezzanine, and equity co-investments.

Hidden River Beats Target on First Fund

June 13, 2023 by John McNulty

Hidden River Strategic Capital has held an above-target close of its inaugural fund, Hidden River Strategic Capital I LP, with $245 million of committed capital.

Hidden River invests from $5 million to $25 million of junior debt and preferred equity in companies that have more than $10 million in revenue and positive cash flow across a range of industries. Many Hidden River transactions are used for growth capital, acquisitions, and inactive shareholder recapitalizations.

The firm was founded in 2021 by Steve Gord, Todd Morrissey and Kevin Condon and is headquartered near Philadelphia in Chesterbrook, Pennsylvania. Messrs. Gord and Condon previously worked together at Philadelphia-based Boathouse Capital, and Mr. Morrissey is a former partner at Philadelphia-based LLR Partners.

“Private lower middle market businesses tend to face a funding void between the often rigid investment approaches of traditional credit funds and the overly dilutive, controlling approaches of growth equity and buyout funds,” said Mr. Gord. “We started Hidden River to address this gap in the market with our structured capital offering – flexible, hybrid debt and equity.”

“Throughout their investment careers, our founders have consistently seen small companies struggle to find the right partner when the capital need sits somewhere between the traditional boxes of mezzanine debt and growth equity,” said Graham Bachman, a managing director and head of business development at Hidden River. “We look forward to providing funding solutions to owner-operators that don’t saddle them with inflexible debt on the one hand or crowd them out as leaders of their business on the other.”

“We are grateful to our limited partners for their support and belief in our approach and are excited to execute on our differentiated strategy,” added Mr. Gord.

To date, Hidden River has not closed on any investments for Fund I.
