TRC Companies Inc. Acquires GNA, Expanding Climate Solutions with the Addition of Sustainable Transportation Solutions

June 6, 2023

WINDSOR, Conn.-Today TRC Companies, Inc. (TRC) announced the acquisition of Gladstein, Neandross & Associates (GNA), the leading North American consulting firm specializing in low- and zero-emission transportation technologies, infrastructure, and ultra-low carbon fuels for commercial transportation. During the past 30 years, GNA has managed the design and development of more clean fleet deployment projects than any other firm in North America, fueled by the firm’s industry-leading grant-writing and management team. Using its proprietary Funding 360 product, GNA has helped its clients track, apply for, and secure more than $1 billion in incentives for clean commercial vehicles and infrastructure.

“GNA’s unmatched sustainable transportation expertise, combined with TRC’s experience with developing energy supply and delivery systems, expands our Climate Solutions offering and helps us accelerate the zero-emission vehicle transition,” said Christopher Vincze, Chairman and CEO of TRC. “Together, we bring new capabilities and broader support to our clients and utility partners as they address the challenges of fleet electrification.”

A core focus of GNA’s business is working with the nation’s most progressive commercial fleet operators to develop and execute clean fleet strategies that achieve their economic and environmental sustainability goals, navigate regulatory requirements, and maximize the financial benefits through public incentives, low carbon fuel standard (LCFS) credits, and more. GNA also works with the leading truck and vehicle manufacturers (OEMs), infrastructure developers, and technology and fuel providers to bring advanced transportation and energy solutions to market.

To further drive market adoption of sustainable transportation solutions, GNA also operates a full-service creative services group to provide expert marketing, media, and communications services to its clients in the advanced transportation space, while also producing industry-leading educational events and tradeshows, including its flagship event, the Advanced Clean Transportation (ACT) Expo.

“We have seen tremendous growth in our business in recent years as governments, OEMs, and fleet operators make significant investments in zero-emission commercial vehicle technologies, driven by an unprecedented volume of public incentive funding, consumer pressures, and ever-growing climate policies and regulatory mandates,” noted Erik Neandross, CEO of GNA. “We are extremely excited about this next step in GNA’s journey. As the transportation sector moves to zero-emission technology in the coming decades, TRC’s scale and capabilities, alongside their leadership position in delivering Climate Solutions and their efforts in advancing the broader energy transition, provides an extraordinarily strong foundation for our sustained growth, enabling comprehensive support to our clients.”

Sean Turner, GNA’s COO, added, “TRC’s deep energy industry expertise, enduring utility relationships, utilization of cutting-edge digital and technology solutions and unparalleled engineering, regulatory, environmental and climate consulting capabilities ensures continued growth and support for our shared clients as they navigate the transition toward zero-emission technologies and fuels in the coming decades.”
