Kissner Group Holdings Acquires NSC Minerals

January 16, 2019

The Stephens Group, LLC (“The Stephens Group”) announced that it has recently sold its interests in NSC Minerals Ltd (“NSC” or the “Company”) to Kissner Group Holdings LP, the parent company of a leading bulk salt, specialty packaged salt and evaporated salt producer. NSC is a market-leading provider of salt products in Western Canada and the North Central United States that was acquired by Altas Partners in October 2013. Stephens Group was a co-investor with Altas Partners in the transaction. Financial terms of the transaction were not disclosed.

NSC is a leading producer of salt and calcium chloride products to provincial, state, and municipal governments, contractors, and industrial customers. The Company offers a wide range of bulk, industrial, and packaged products used in critical applications such as road de-icing.

NSC will continue to operate under its existing brand as a subsidiary of Kissner. The Company’s production, packaging, and storage facilities in Canada and the U.S. will remain fully operational.

“NSC is a well-run and highly complementary addition to our growing platform and solidifies Kissner’s position as one of North America’s premier, multi-regional salt companies,” said Mark Demetree, Executive Chairman and Chief Executive Officer of Kissner Group Holdings LP. “With its strong position in the Western Canada highway de-icing salt market and growth potential in the calcium chloride market, NSC expands our geographic presence in Canada and enhances our financial scale and flexibility with non-cyclical, recurring revenue. I look forward to welcoming the talented NSC team to Kissner as we pursue our next phase of growth together.”

“We are pleased to continue to help expand Kissner’s geographic footprint and aggressively support the company’s management team in their growth efforts,” said Jeffrey Siegal, Partner at Metalmark Capital. “We look forward to our continued work with this great company to further its capabilities to deliver exceptional products and service to its customers.”

“It has been a privilege to partner with Malcolm Leggett, NSC’s visionary founder, CEO Neil Cameron and the entire NSC team over the past many years,” commented Andrew Sheiner, Founder and Managing Partner of Altas Partners. “Through a collaborative partnership, we were able to enhance operational performance considerably, driven by logistics optimization and strategic capital investment throughout NSC’s network. We wish the NSC team all the best as they continue to build this wonderful business in the years to come.”

“We enjoyed the collaborative partnership with NSC’s management team as well as Altas Partners,” said Jim Jacoby, Managing Director with Stephens Group. “From the initial investment in 2013 to the recent sale to Kissner the entire team worked hard to position NSC for success. This transaction is the culmination of this effort and it’s been very rewarding to work alongside such a dedicated group.”

The transaction closed January 16, 2019.
