Chartwell Advises RESPEC on Acquisition of PDC Engineers

May 2020

Chartwell is pleased to announce RESPEC, Inc. has acquired PDC Inc. Engineers. The transaction brings together two 100% ESOP-owned companies with over 110 years of industry experience and combined revenue of $80M. The collective company will continue to operate under the RESPEC banner.

RESPEC (the “Company”) engaged Chartwell as its exclusive financial advisor to lead and execute a complex transaction involving the combination of two 100% ESOP-owned companies and their respective plans. Throughout the process, Chartwell provided objective counsel and facilitated negotiations on behalf of the Company to ensure a successful outcome for both parties. Chartwell conducted in-depth analyses to advise RESPEC on investment merits, valuation, transaction structuring, and ESOP related matters.

“We are no strangers to the M&A process and I personally have interacted with many financial professionals throughout my career. We selected Chartwell to lead this important endeavor based on Chartwell’s ability to leverage its team of professionals to provide unbiased, comprehensive advice throughout the transaction process. Chartwell’s ability to navigate through a complex ESOP transaction during one of the more complex times in recent history was invaluable. It was comforting to know we had a reliable and responsive partner to help us cross the finish line.”
