Cleantek Industries Inc. First Quarter 2026 Interim Update

Calgary, Alberta--(Newsfile Corp. - May 21, 2026) - Cleantek Industries Inc. (TSXV: CTEK) (" Cleantek " or the " Company "), a leading provider of patented energy technology solutions that reduce cost and carbon intensity in the wastewater management and industrial lighting sectors, is pleased to provide a business update and unaudited financial highlights for the three months ended March 31, 2026. During the quarter, the Company increased investments in strategic growth initiatives and upcoming projects expected to drive future revenue growth, including expenditures tied to its previously announced large international HALO SE project scheduled to commence in Q2 2026. "Our first quarter results reflect a deliberate investment phase for the Company," said Riley Taggart, Chief Executive Officer.

"We have continued to deploy capital and resources toward the construction of our international sales units. While these investments impacted near-term results, they are aligned with our broader strategic objectives and expected future demand." Q1 2026 HIGHLIGHTS Manufacturing of HALO SE Crown Mount units for the international contract is actively underway at the Company's Crossfield, Alberta facility; revenue recognition is anticipated to commence in late Q2 2026 and continue through Q3 2026. The HALO International Program is expected to represent the largest single-contract revenue event in the Company's history.

Revenue of $3,514 for Q1 2026, with core North American rental activity remaining steady at $3,349. Net income of $217, maintaining profitability through a quarter of elevated pre-revenue investment activity. Adjusted EBITDA of $1,001 (28% margin), with near-term compression reflecting upfront costs associated with scaling for international contract delivery.

Working capital improved to a surplus of $835 at March 31, 2026, from a deficit of $(482) at December 31, 2025, supported by inventory and prepaid build for the HALO International Program and a significant reduction in the bank operating line balance. Shares outstanding as at May 21, 2026: 29,485,376. SELECTED FINANCIAL INFORMATION (Canadian $000's, unaudited, except per share amounts)   ¹ Non-IFRS measure.

See Non-IFRS Measurements section. CAPITAL STRUCTURE (Canadian $000's, unaudited)   Working capital improved by $1,317 quarter-over-quarter, driven by inventory and prepaid build for the HALO International Program and a reduction in the bank operating line balance from $1,046 to $245. Non-current debt increased to $7,581, reflecting net drawdowns on the BDC manufacturing facility to fund fleet additions and contract-related capital expenditures.

Shareholders' equity increased to $3,097, driven by Q1 net income and a $183 foreign currency translation adjustment. OPERATIONAL PRIORITIES AND OUTLOOK Cleantek enters the balance of 2026 with a contracted international revenue catalyst in active execution, a North American rental base operating at stable utilization, and the expansion of international opportunities. The Company's near-term operational priorities include: Executing on delivery and installation of up to 60 HALO SE Crown Mount lighting systems under the HALO International Program, with revenue recognition anticipated commencing in late Q2 2026; Sustaining and growing North American rental utilization across the lighting and wastewater treatment fleets; Advancing the EcoSteam program, which continues to generate positive customer response and positions Cleantek to address growing operator demand for emissions-reduced wastewater treatment; Expanding international sales and rental activity in markets where the HALO SE Crown Mount has demonstrated performance; and Evaluating acquisition and merger opportunities that expand product offering, customer reach, or geographic presence, with a longer-term objective of accessing broader capital markets including a potential TSX uplisting.

Management maintains the Company's EBITDA outlook for 2026, citing a growing list of opportunities and improving market conditions across several key operating regions. "We continue to see encouraging activity levels within our target markets," added Riley Taggart. "Our focus remains on disciplined growth, operational execution, and positioning the Company to capitalize on opportunities currently in development."
