Back in 2021, I authored a piece titled "How Private Equity Is Quietly Transforming the A/E Industry". My goal back then was to describe and justify the factors driving outside investor interest in our sector and why so many design leaders initially seemed receptive to it. The marriages seemed a bit unconventional. Cerebral, creative and technical architects and engineers joining forces with financiers and dealmakers. And while other executives viewed this with a mix of curiosity and skepticism, the big question was whether this trend, still in its early innings, was sustainable? Well, five years later, the answer is a resounding yes.

In fact, this decade has seen professional services companies of all stripes being swept up by private equity investment. Accounting firms, medical and dental practices, wealth management providers, recruiting/placement specialists, and strategy and marketing consultants have all teamed up with financial sponsors for exit-strategy purposes. 

The trickle of sellers that kicked off this movement has since become a torrent as the pace of deals has broadened and accelerated. In the last five years, the A/E industry has witnessed over 100 firms take the private equity route through various models. Companies across every discipline and geography. ENR 500 firms, as well as those that aspire to be. Rather than seeing failed outcomes and incompatible partnerships, the model's success has actually emboldened an industry open to change. A/E leaders who could have sold to publicly traded companies or large, privately held strategics, or even implement ESOPs, changed course with a profound, new option in front of them. The lure of selling at an attractive EBITDA multiple, with the prospect of future growth and arbitrage ahead of the next recapitalization event, has proven too good to pass up. 

Select New A/E Firm Private Equity Recapitalizations – 2024 to Present

The thesis driving soaring transaction volumes remains the same. Private equity firms invest in established companies and seek higher returns on behalf of their limited partners, such as family offices, high-net-worth individuals, pension funds, endowments, and foundations. They understand the attractiveness of our industry's macro forces such as infrastructure renewal, environmental concerns, insatiable power/energy needs and facility modernization. To them, it's another highly fragmented industry ripe for consolidation, led by professionals with limited transition or succession options. Investors also like design firms' cash flow generation and debt capacity, as well as their incredible scalability.

What has changed somewhat over the last five years is the investment strategy being employed. Early on, it was the sizable design firm ($50-100 million+ revenue) that was being recapitalized. It kept its brand, services, and overall principles and culture. It was utilized as the sole platform for bolt-on acquisitions to scale and diversify. And while those are still sought after, today's lower-middle market investors have acquired much smaller A/E firms, often with less than $20 million in revenue. Others have adopted the "family of brands" approach. This involves acquiring disparate, smaller consulting firms ($5-$25 million) across the country and slowly bringing them together under a common holding company and identity. This model typically brings in an external, experienced industry leader to steer the entire ship. 

Other observations and takeaways include:

1. Buy or build tailwinds – To be sure, private equity partners can help accelerate growth by scooping up other firms. Dozens of PE-backed firms have been some of the most aggressive acquirers during this "M&A Supercycle" era. But not all of them have been. With impeccable timing, financial sponsors have been fortunate to see the A/E industry generate its strongest organic growth rates since the mid-2000s. With backlogs at record levels, many organizations have flourished by steadily achieving annual growth rates of 10-20% and sidestepping the integration challenges that come with serial acquisitions. 

2. The benefits of an external perspective – One of the refreshing attributes private equity groups can bring is a true outsider lens to a business. And why not? These groups invest in a variety of industries, including manufacturing, energy, logistics, retail, and software. Company challenges can be universal and relatable. Some A/E CEOs have shared that leveraging experiences and best practices with other portfolio CEOs has been helpful, enabling them to challenge historical A/E "groupthink" dynamics. PE investors can leverage case studies and new ideas to coach, plan strategically, train and test, manage finances, and develop businesses. In addition, many are seizing the opportunity to widely incorporate AI for value creation and as a competitive differentiator.

3. Ready, set, exit – Private equity has a preferred investment horizon (3-5 years, more or less) when they acquire and grow a company before selling it and returning capital (with returns!) back to their limited partners. In most cases, this occurs in a secondary sale, with ownership transferred to another financial sponsor. Already, we've seen numerous A/E firms that initially recapitalized in the 2019-2022 period find homes with new partners. Less common have been sales to publicly traded firms or mergers of two PE-backed firms. Timing and market conditions are always unpredictable. And with an overhang of A/E investments today, it's worth asking whether that could result in stalled exits, liquidity setbacks, or value dilution.

4. More deals to come? – Are there more private equity investments looming on the horizon? Yes, obviously, discussions are ongoing between parties, and it's unlikely we're in the final stages of this cycle. On the other hand, how many more will occur is a bit nebulous. Keep in mind that a good number of ENR 500 firms are already with financial partners, and many others on that list are perfectly satisfied with their independence and path. Some firms with legacy or mature ESOPs could find an organizational reset appealing. Today, we're also observing a new, younger generation taking over the C-suites at design firms everywhere. Our hunch is that these individuals may be more interested in maintaining control and independence than selling out to buyers or investors.

A great aspect of the A/E industry is that it encompasses a "big tent" of diverse ownership models – from sole owners and partners to ESOPs, family businesses, widespread shareholder groups, and publicly traded companies. Each has its unique benefits, and ultimately, there is no direct correlation between a firm's ownership structure and its financial performance. This decade, private equity has emerged as a viable option for many firms, but it's not for everyone. It is, however, here to stay.
