Willdan Acquires Energy Engineering Firm Newcomb Anderson McCormick, Inc.

Willdan Group, Inc. (NASDAQ: WLDN) announced today the acquisition of Newcomb Anderson McCormick, Inc. (NAM), an energy engineering and consulting company with offices in San Francisco and Los Angeles that provides clients with mechanical engineering expertise and comprehensive energy efficiency programs and services.

Through its 13-year history, NAM has developed energy efficiency projects, distributed resources, and strategic energy plans and programs primarily for municipal and higher education customers. NAM’s key clients include Pacific Gas & Electric Company, Southern California Edison, the City of San Francisco, and local governments throughout the state of California. NAM has also managed publicly funded energy efficiency partnership programs serving 33 campuses in the University of California and California State University systems, 72 California community college districts, and 34 state correctional facilities.

NAM’s team of engineers have analyzed a diverse collection of buildings, including school districts, military bases, and over 300 state-owned buildings. Additionally, NAM’s statewide higher education utility partnerships have resulted in the implementation of more than 3,000 projects, realizing over $200 million in annual savings a year. NAM has also evaluated or managed the procurement and installation of over 250 MW of solar photovoltaic systems, primarily in the public sector.

“NAM significantly strengthens Willdan’s engineering expertise in California,” said Tom Brisbin, Willdan’s Chairman and CEO. “Their experience in renewable energy and sustainability planning adds valuable insight into addressing the challenges ahead. Together, NAM and Willdan will pave the way for major changes in California’s energy efficiency programs, including significant reductions in emissions and energy consumption, as well as the transformation toward zero net energy buildings for utilities and cities. We’re excited to welcome all of the NAM employees to Willdan.”

“As part of Willdan, NAM will benefit from Willdan’s broad range of energy solutions, as well as relationships with major utilities and more than 400 California municipalities,” said John Newcomb, NAM’s founder. “We look forward to being able to provide our clients and employees with a more complete range of solutions and opportunities to solve their critical energy and sustainability challenges.”

The acquisition of NAM was completed on April 30, 2018. Willdan expects that the NAM acquisition will add approximately $7 million in annual revenue.
