Increase in acquisitions drives growth in revenues for environmental and sustainability consulting firms

In recent years, the revenue growth of prominent E&S consulting firms has been significantly driven by merger and acquisition (M&A) activities, as highlighted in the data compiled by Environment Analyst’s Global Market Assessment. A new report on M&A opportunities in the environmental and sustainability consulting sector showcases insights gleaned from nearly 500 deals completed between 2019 and 2024. The amalgamated data from published sources and Environment Analyst’s estimates illustrates that companies under scrutiny, which represent about 65% of the global E&S consulting market, have witnessed revenue growth through acquisitions amounting to a minimum of $5.7 billion within the specified timeframe. The total revenue surge during this period reached $15.7 billion.

The top five acquirers in this realm between 2019 and 2024 were identified as WSP, Tetra Tech, Stantec, RSK, and SLR Consulting. These industry players have engaged in a series of strategic acquisitions to expand their service offerings and bolster their market presence. For instance, WSP executed 23 acquisitions during this period, accumulating total revenues of $2.6 billion from these deals. Noteworthy acquisitions by WSP include E&I UK, Golder, Ecology & Environment Inc, and Power Engineers.

Similarly, Tetra Tech, Stantec, RSK, and SLR Consulting have also actively pursued acquisitions to enhance their business portfolios and cater to a wider range of client needs. Tetra Tech secured $885 million in total revenues from 16 acquisitions, while Stantec completed 18 deals worth $618 million, including the hefty $550 million acquisition of Cardno. RSK emerged as the most prolific acquirer with a whopping 115 deals contributing at least $324 million in revenue to the company. SLR conducted 30 acquisitions, bringing in a minimum of $268 million in revenue, with notable inclusions like Wardell Armstrong.

The popularity of specific regions and services in the E&S consulting sector becomes apparent through the observed deal patterns. The UK and US emerged as the frontrunners in terms of acquisition numbers, with Australia following closely behind. The variety of acquisition targets is indicative of a broad diversification in service offerings, with acquisitions spanning over 32 different types of services outside the traditional energy, infrastructure, water, ecology, and ESG domains.

In conclusion, the data presented in Environment Analyst’s M&A data pack sheds light on the strategic growth trajectories of key players in the E&S consulting sector. By analyzing a comprehensive list of M&A activities, companies can better understand the landscape of acquisitions and divestments. The information encompassing acquirer and target names, deal years, target companies’ regions and service areas, and revenue estimates provides valuable insights into the dynamics of the E&S consulting market.
