The Riverside Company to Exit AERCO

November 7, 2014 by John McNulty

The Riverside Company has entered into an agreement to sell AERCO International to Watts Water Technologies for $264.5 million in cash for 100% of the equity of the company on a cash and debt free basis.

AERCO, acquired by Riverside in 2007, is a manufacturer of high-efficiency condensing boilers and tankless water heaters that are distributed primarily in the United States to the commercial markets.  The company had trailing twelve months sales through September 2014 of approximately $100 million. The company was founded in 1949 by Henry Angelery as the Angelery Engineering Research Company (AERCO). AERCO is headquartered north of New York City in Blauvelt, NY (www.aerco.com).

“Our success with the AERCO investment is a result of a partnership with an outstanding management team who shared our vision for the company,” said Riverside Partner Steve Dyke. “We worked with them on a number of successful growth initiatives, and AERCO is a much bigger and better company as a result.”

During Riverside’s ownership period, AERCO opened a state-of-the-art manufacturing facility and R&D lab, launched a line of tankless water heaters, broadened its boiler product line, and revamped its sales and marketing approach and go-to-market strategy.

“It’s been wonderful to work with the Riverside team,” said AERCO CEO Ervin Cash. “They provided resources and support that allowed us to thrive and positioned us for continued success. AERCO is in a very strong position with a bright future.”

Working on the transaction with Mr. Dyke from Riverside were Vice President Ben Davis and Associate Conor Cook. Origination Principal Amy Margolis helped facilitate the exit for Riverside.

KeyBanc Capital Markets and Jones Day advised Riverside on the transaction.

The Riverside Company is a global private equity firm focused on investing in and acquiring growing businesses valued at up to $250 million (€200 million in Europe). Since its founding in 1988, Riverside has invested in more than 360 transactions. The firm’s international portfolio includes more than 75 companies. Riverside is headquartered in New York with additional offices in Atlanta, Chicago, Cleveland, Dallas, Los Angeles, San Francisco, and London (www.riversidecompany.com).

The buyer of AERCO, Watts Water Technologies (NYSE: WTS), is a maker of products used to control the efficiency, safety, and quality of water within residential, commercial, and institutional applications. The company, with annual revenues of approximately $1.5 billion, was founded in 1874 and is headquartered in North Andover, MA (www.wattswater.com).

The Riverside Company Acquires EcoSmart

October 2, 2013 by John McNulty

Eemax, a portfolio company of The Riverside Company, has completed the add-on acquisition of EcoSmart. Both Eemax and EcoSmart design and sell electric tankless water heaters.
The addition of EcoSmart will also boost Eemax’s manufacturing capabilities and allow the company to expand its geographic coverage, most notably in Florida and Latin America. The acquisition is complementary to Eemax’s business due to EcoSmart’s residential products and customers.

“We’re delighted to bring EcoSmart’s innovative products and design knowhow into the Eemax fold,” said Riverside Managing Partner Loren Schlachet. “EcoSmart’s tankless water heaters have earned a reputation for reliability and innovation, and the deal enhances Eemax’s offerings while providing even more choice to a broader array of customers.

Eemax is based in Waterbury, CT (www.eemax.com) and EcoSmart is based in Miami Gardens, FL (www.ecosmartus.com).

“EcoSmart has a strong distribution network and an outstanding online presence to complement its excellent product line,” said Riverside Vice President Joe Manning. “We are excited about leveraging those strengths to continue growing Eemax and EcoSmart together.”

Working with Mr. Schlachet and Mr. Manning on the transaction for Riverside were Senior Associate Elaine Ho; Operating Partner Jeff Tobin; and Operating Executive, Finance David Pecore. Operating Partner and Managing Director for Riverside in Asia Brian Bunker helped the deal team with due diligence.

The Riverside Company is a private equity firm focused on the smaller end of the middle market (“SEMM”). Riverside specializes in investing in SEMM companies (those valued up to $250 million) and partners with management teams to build companies through acquisitions and value-added growth. Since 1988, the firm has invested in more than 310 transactions with a total enterprise value of more than $6 billion. The firm’s current portfolio includes more than 70 companies. The Riverside Company is headquartered in New York with additional offices in Atlanta, Chicago, Cleveland, Dallas, Los Angeles, San Francisco, and London (www.riversidecompany.com).

Webster Bank provided financing for the transaction. Deloitte & Touche advised Riverside on financial due diligence.
