CALGARY, AB / ACCESS Newswire / April 20, 2026 / NXT Energy Solutions Inc. ("NXT" or the "Company") (TSX:SFD)(OTCQB:NSFDF) is pleased to announce the appointment of Gerry Sheehan as Chief Executive Officer, effective April 20, 2026. Mr. Sheehan is a professional geologist, geophysicist and executive manager serving as a director of NXT since 2021. Mr. Sheehan's experience and relationships will add great value to NXT as the company scales up its survey activities in areas of substantial potential in a world demanding new sources of oil and gas. His 40 years of experience have included early-stage oil and gas basin evaluation, field appraisal and development, satellite remote sensing and non-conventional resource assessments working with government, large and small E&P independents, State oil companies and regulators. His technical and business development experience in Africa, South Asia, and Europe aligns with NXT's growth initiatives. Mr. Sheehan's many accomplishments include being a founding member of the technical team of Tullow Oil Plc for almost 20 years where he served as International Exploration Manager from 1998 to 2004 directing technical activities on wide geographies including North and West Africa, the Indian subcontinent and Europe.

Mr. Sheehan succeeds Bruce G. Wilcox, who is retiring, but remaining on the board of directors, having served as CEO since 2023. NXT is embarking upon the third major stage in the company's evolution. The first was the development and demonstration of the efficacy of stress field detection, under inventor and former CEO George Liscicasz, resulting in patents in 47 countries. The second was a critical stage of contract and revenue growth, under Mr. Wilcox, based upon his many years in the financial industry. The third under Mr. Sheehan will expand services, resources, geographies and clients for NXT. Like Mr. Sheehan, Mr. Wilcox stepped up from the board of directors to the CEO position. NXT has a highly focused management team and board that are in continuous active engagement.

Mr. Wilcox said, "It has been my privilege to lead NXT through a transformational period over the last three years. Gerry is a seasoned, industry-recognized geophysicist and has extensive operational executive experience in the energy sector in our core jurisdictions and prospective geographies. The NXT board and I believe his skill set is ideal for advancing our operations and financial progress."
