**Kelso Technologies Inc. <br>Announces Change of Auditor**

**West Kelowna, British Columbia and Bonham, Texas** - Kelso Technologies Inc. (TSX: KLS) ("**Kelso**" or the "**Company**") is pleased to announce that is has appointed CBIZ CPAs P.C. ("**CBIZ**" or "**Successor Auditor**") as the Company's new public accounting firm, effective October 6, 2025.

CBIZ was appointed following the receipt by the Company of the formal resignation of Smythe LLP ("**Smythe**" or "**Former Auditor**") effective September 25, 2025. The Audit Committee of the Board of Directors (the "**Audit Committee**") accepted the resignation of Smythe as the Company's independent registered public accounting firm due to a change in Smythe's policies.

The Board of Directors of the Company, on the recommendation of the Audit Committee after reviewing multiple accounting firm proposals, selected CBIZ as the new auditor until the next Annual General Meeting of the Company.

"CBIZ is ranked among the top 10 public accounting firms in the United States. Their worldwide coverage will be a great asset in Kelso's next phase of growth, and we look forward to working with them," said Mark Temen, independent director and Audit Committee Chair.

The Company has sent a Notice of Change of Auditor (the "**Notice**") to the Former Auditor and to the Successor Auditor and has received a letter from each, addressed to the securities commissions in each of British Columbia, Alberta and Ontario stating that they agree with the information contained in the Notice. The Notice and letters have been reviewed by the Company's Board of Directors.

The Notice, together with the letters from the Former Auditor and the Successor Auditor are available on <u>SEDAR+</u> in Canada and on <u>EDGAR</u> in the United States.
