All amounts are presented in this news release are in United States dollars (“U.S. dollars”), unless otherwise indicated.

Q4 2025 FINANCIAL HIGHLIGHTS

• Revenue increased by approximately 19% year-over-year to $14.9 million, reflecting a new corporate milestone for revenue generated in a quarter. Revenue from Connected Devices and Infrastructure (“Connected Devices”) increased by $1.6 million or 21% and Utility Software Applications and Services (“Software and Services”) revenue increased by $0.7 million or approximately 15%. The increases in revenue were a result of adding new customers and continuing to expand deployments with existing accounts. Recurring Revenue¹ increased by 38% to $4.1 million and represented 28% of total revenue in the quarter.

• Gross Profit¹ improved by 27% to $8.3 million from the prior year with contributions from both operating segments. Overall Gross Profit Margin¹, on a consolidated basis, increased by 350 basis points to 56% primarily due to the mix of products shipped within the Connected Devices segment and strong contributions from the Software and Services segment.

• Income for the period was $179,000 compared to income of $289,000 last year.

• The Company delivered positive Adjusted EBITDA¹ of approximately $1.3 million, which was effectively in-line with the prior year (December 31, 2024: $1.4 million) as the Company increased headcount and incurred higher operating expenses.

• The Company generated positive Cash Flow from Operating Activities of $3.3 million.

• At December 31, 2025, Tantalus had available liquidity of $21.1 million compared to $18.0 million as at December 31, 2024. The available liquidity was comprised of a cash balance of $12.6 million and borrowing availability of $8.5 million under its revolving line of credit.

2025 FINANCIAL HIGHLIGHTS

• The Company delivered record revenue of $54.1 million, representing 22% growth year-over-year. Revenue from Connected Devices increased by 28% to $35.3 million as a result of higher sales volumes and Software and Services revenue increased by 13% to $18.8 million as a result of higher annual maintenance billings. Recurring Revenue¹ increased by 20% to $13.9 million, representing 26% of total revenue for the year.

• Annual Recurring Revenue (“ARR”)¹ grew by approximately 14% year-over-year to $14.5 million as of December 31, 2025 (December 31, 2024: $12.7 million).

• Gross Profit¹ increased by 23% to $29.6 million while Gross Profit Margin¹, on a consolidated basis, remained stable at approximately 55%.

• Loss for the year was $992,000, compared to a loss of $2.6 million last year with the improvement arising from revenue and margin growth.

• Diluted Loss per Share was $0.02 compared to $0.05 in the prior year period.

• The Company delivered record Adjusted EBITDA¹ of $3.4 million, representing approximately 156% growth year-over-year (December 31, 2024: $1.3 million). The growth in Adjusted EBITDA reflects operating leverage in the business model as the Company scales revenue.

• The Company generated positive Cash Flow from Operating Activities of $4.7 million compared to $2.6 million in the prior year.

“Tantalus is grateful to our team, customers and partners who helped the Company deliver another year of commercial and financial milestones, including record results in revenue, adjusted EBITDA and sales orders,” said Peter Londa, President & CEO of Tantalus. “We continue to invest in innovative solutions that deliver cost-effective and low-risk paths to improve our customers’ systems and operations. Our vision for data-centric distribution grid modernization and Unified Intelligence is resonating with an expanding number of utilities and positions us to maintain our growth trajectory heading into 2026.”

OTHER KEY DEVELOPMENTS

• Sales Order Conversion: During Q4 2025, the Company converted $11.0 million in orders from its sales pipeline bringing the total amount in 2025 to a record level of $64.9 million. The results represented approximately 27% growth year-over-year and a book-to-bill ratio of 1.2x.

• Growth of User Community: The Company added 5 new utilities in Q4 2025 and 17 for the full year, demonstrating a continued ability to convert new accounts from its sales pipeline.

• TRUSense Gateway™ Progress: As of the date of this news release, 66 utilities submitted orders to trial, pilot and/or deploy the TRUSense Gateway. The adoption of the TRUSense Gateway is being driven by a combination of existing customers seeking to enhance deployments of Tantalus’ broader offerings and utilities that are ordering from the Company for the first time to accelerate their grid modernization journeys.

SUBSEQUENT EVENTS

• Appointment of New Board Member: On January 26, 2026, the Company announced the appointment of Susanna Zagar to its Board of Directors. Ms. Zagar most recently served as the CEO of the Ontario Energy Board and brings broad industry and governance expertise to the Company.

• Completion of CAD$23.0 Million Bought Deal Financing: On February 9, 2026, the Company completed a bought deal offering of 4,299,575 shares at a price of CAD$5.35 per share for total gross proceeds of approximately CAD$23.0 million. The Company intends to use the net proceeds of the offering for sales and marketing, strategic growth initiatives, partial repayment of the Company’s Term Loan, capital expenditures, research and development, and working capital and general corporate expenses.

• Changes in Import Tariffs: On February 20, 2026, the US Supreme Court ruled that the International Emergency Economic Powers Act (IEEPA) does not authorize the President to impose tariffs. As a result, on the same day two executive orders were issued, one prospectively suspending the original IEEPA tariffs, and another establishing the continuing suspension of duty-free de minimis treatment for certain imports to the US and the mechanisms for continuing to collect duties on such shipments and the rates of such duties. To the balance sheet date, $2.1 million has been paid in tariffs. There remains uncertainty as to any right of refund of the tariffs and the process required to collect eligible refunds (if any), as well as any contractual obligations to return amounts previously collected from customers.

The Company will hold a conference call and webcast to discuss the financial results on Thursday, March 19, 2026, at 11:00 am Eastern Time.
