 NXT Energy Solutions Inc. Announces Management Change

CALGARY, ALBERTA, MAY 17, 2016 – NXT Energy Solutions Inc. (“NXT Energy” or the “Company”) (TSX:SFD; OTC QB:NSFDF) announces that Bev Stewart has joined the Company as VP Finance and Chief Financial Officer. Bev is a CPA with over 20 years’ experience in senior financial roles within the international energy and oil and gas industries. She was formerly Chief Financial Officer of TransCanada Turbines Ltd (TCT), a joint venture company owned by TransCanada Pipelines and Wood Group Plc.

Bev is succeeding Greg Leavens who has served as NXT’s VP Finance and CFO since July 2011.

As CFO of TCT, Bev was instrumental in the successful growth of the organisation into international markets such as South America, the Middle East and Asia. She has an impressive track record in negotiating large foreign contracts and her many years of dealing with the complex commercial and tax matters in these regions will be of great value to NXT. During her tenure at TCT, Bev made significant improvements to the financial strength of the organisation. Under her direction, the business decreased its borrowings by over 50% as a result of reducing costs and improving capital management.

“We are excited to welcome Bev to the NXT management team” said George Liszicasz, President and CEO of NXT. “Her extensive knowledge and experience in dealing in overseas markets will provide much needed support and leadership to our team as we continue to develop new opportunities.”

“NXT and the Board of Directors wish to thank Greg for his contributions over the past 5 years and wish him the best in his future endeavors.”
