Environmental Technology Company Acquires a Leading Industrial Air Filtration Company

The environmental technology company, Nederman Holding AB, represented by Sullivan, recently acquired a leading industrial air filtration company RoboVent, significantly strengthening its North American position by becoming the number one player within the U.S. weld fume extraction segment. Sullivan has provided acquisition advice to Nederman since 2017. Sullivan’s Environment & Natural Resources group handled preparation of environmental provisions of the purchase agreement and disclosure schedules and advised as to regulatory compliance at the target company.

Sullivan Shares Cross-Border Deal of the Year Award With Two Clients at M&A Advisor Awards

In November 2021, Sullivan together with its clients Merger & Acquisition Services, Inc., and International Transportation Marine Office, LLC (ITMA) received the Cross-Border Deal of the Year ($50 to $100 million) Award, at the 20th Annual M&A Advisor Awards in New York City. The award was given for the sale of ITMA to MS Amlin Underwriting Limited, a UK company. Don Kaitz retained his role as chairman of Arizona-headquartered ITMA, and the business continued to be led by Eric Kaitz, Chief Executive Officer. Earlier in 2021, Douglas Stransky and Michael Student, along with Merger & Acquisition Services Inc., advised ITMA and the Kaitzes.

Partner and head of Sullivan's International Tax Group, Douglas Stransky, commented, "We are thrilled to receive this honor and be together in-person with our clients and friends, Merger & Acquisition Services, Inc. and Don and Eric Kaitz, and proud to have collaborated with them on this sale."
