NXT Energy Solutions Announces 2025 Year-End Results

CALGARY, AB, March 31, 2026 – NXT Energy Solutions Inc. ("NXT" or the "Company") (TSX: SFD; OTCQB: NSFDF) today announced financial and operating results for the quarter and year ended December 31, 2025. Dollar amounts are in Canadian Dollars, unless otherwise identified.

Bruce G. Wilcox, CEO of NXT, commented, “2025 has been a transformational year for NXT. Strategic initiatives undertaken in 2023 are now taking shape. Revenue increased 2,437% to $16.4 million in 2025 compared to $0.6 million in 2024. Operating cash flow improved $5.1 million, net working capital improved $11.9 million or 179%, and Net loss improved by $6.8 million or by $0.10 per share-basic and share-diluted, in comparison to 2024. These positive financial numbers were the direct result of our newly implemented multi-regional growth strategy showing impactful progress and included three SFD^® surveys being executed with one repeat, and two new customers.

In December 2025 we acquired full ownership and all future rights and applications for the SFD^® technology. This now gives NXT freedom to develop new commercial applications for the SFD^® technology in areas the Company deems beneficial to increasing shareholder value.

In November 2025, we secured a US$2.0 million investment to advance the application of the SFD^® technology, a meaningful opportunity to unlock shareholder value from NXT's extensive proprietary SFD^® data library, which includes more than 50,000 line-kilometers of airborne geophysical data in the Western Canadian sedimentary basin. With this progress, 100% of convertible debenture holders showed their confidence by converting their outstanding convertible debentures into common shares at year’s end, giving the Company a stronger balance sheet with strengthened working capital necessary to further this initiative. While the debenture conversion is very positive for NXT, accounting rules require us to book it as a loss, masking positive income in the Company.

2025 represents a clear inflection point for the Company. We have established momentum supported by a stronger financial position, having successfully executed numerous contracts across multiple regions, and obtained 100% ownership of all applications of the SFD^® technology.”

Key financial and operational highlights during the fourth quarter of 2025 are summarized below:

	·	the Company recorded SFD^®-related revenues of approximately $16.35 million for YE-25 versus $0.64 million for YE-24;
	·	Net loss for YE-25 compared to YE-24 improved by $6.76 million or by $0.10 per share-basic and share-diluted;
	·	net working capital (non-GAAP measure defined below) was approximately $5.26 million at December 31, 2025, an increase of $11.9 million since December 31, 2024, or 179%;
	·	cash and short-term investments as at December 31, 2025 were approximately $3.92 million;
	·	on December 23, 2025, NXT acquired all remaining SFD^® rights for all present and future applications, sensor uses, and geophysical targets using SFD^®, and as a result has full ownership of the SFD^® technology;
	·	in December 2025 the Company completed the acquisition phase of the Al-Haj SFD^® Survey in Pakistan;
	·	the Company recorded SFD^®-related revenues of approximately $2.14 million for Q4-25 versus $0.42 for Q4-24;
	·	on November 24, 2025, the Company received a US$2,000,000 strategic investment by way of a private placement of common shares to its largest shareholder MCAPM LP to advance the application of the Company’s proprietary SFD^® technology within select areas of Western Canada;

	·	cash flow provided by operating activities was approximately $1.16 million during YE-25, compared to $3.97 million used by operating activities in YE-24;
	·	cash flow provided by operating activities was approximately $0.43 million during Q4-25, compared to $1.39 million used by operating activities in Q4-24;
	·	for YE-25 the net loss was $2.32 million ($0.02 per share), including non-cash charges for stock-based compensation expenses (“SBCE”), amortization expenses and remeasurement loss, all totaling approximately $8.04 million, versus a net loss of $9.08 million $0.12 (per share) in YE-24;
	·	for Q4-25 the net loss was $1.24 million ($0.01 per share), including SBCE, amortization expenses and remeasurement loss, all totaling approximately $0.08 million, versus a net loss of $2.80 million ($0.04 per share) in Q4-24;
	·	general and administrative (“G&A”) expenses decreased by approximately $0.17 million (16%) in Q4-25 as compared to Q4-24; and
	·	G&A expenses increased by approximately $0.28 million (7%) in YE-25 as compared to YE-24.
	·	The 2025 results were heavily skewed by a non-cash accounting charge. The company recognized a loss of $5.2 million on the fair value remeasurement of its convertible debentures. However, this charge is a direct result of the increase in NXT's common share price during the period and conversion dates, which increased the liability value of the conversion feature. This accounting requirement served to mask a much stronger and positive underlying operational performance. Excluding this non-cash accounting charge, the Company's pre-tax operational performance would shift from a loss of $2.32 million to a profit of approximately $2.88 million, dramatically illustrating the positive impact of the year's commercial success.

Subsequent to December 31, 2025:

	·	the Company completed data interpretation for the AL-Haj SFD^® Survey;
	·	the Company received US$346,500 on February 13, 2026, for the mobilization fee for an upcoming SFD^® survey in Africa; and
	·	100% of all outstanding convertible debentures were converted to common shares by January 5, 2026.
