Kelso Technologies Inc.
Retirement of Chief Operating Officer and Appointment of Director

West Kelowna, British Columbia and Bonham, Texas - Kelso Technologies Inc. (TSX: KLS) ("Kelso" or "the Company") announces that Anthony (Tony) Andrukaitis will retire from the Board of Directors effective June 3rd, 2025, and as Chief Operating Officer effective June 30th, 2025. Executive Vice President Amanda Smith will assume the role of COO starting July 1, 2025. The company and the board are pleased to welcome Mark Temen of Phoenix, Arizona, as the sixth member of the Kelso Board.

Since October 24, 2011, Mr. Andrukaitis has diligently served in his role, effectively building a strong team in Bonham and mentoring Ms. Smith to assume his roles and responsibilities.

"It has been a pleasure working with Tony over the last five years," says Frank Busch, President and CEO. "Tony was particularly helpful through the management changes during summer and autumn of 2024. Tony's guidance with corporate and industry knowledge helped the new management team get up to speed quickly, resulting in a smooth transition."

Mr. Andrukaitis oversaw the operations of the Bonham, Texas facilities as well as the development and production of the Company's rail product line. Tony's retirement was previously delayed due to the difficult period of the COVID 19 pandemic and related rail recession. Tony used some of that time to mentor EVP Amanda Smith to assume his duties as COO.

"Tony's patience, kindness and leadership guided Kelso through extreme business challenges, market fluctuations and economic uncertainties while maintaining a positive culture," says incoming COO, Amanda Smith. "With his industry knowledge, extensive network and relationships, I've been fortunate to have him mentor, support and invest in me and my personal development as his successor."

The Company anticipates a seamless transfer to Ms. Smith on July 1^st, 2025, at which time she will fully assume the role of COO. As part of management's ongoing efforts to reduce expenses, the position of Executive Vice President of Operations will be eliminated.

The Corporate Governance and Nominating Committee is pleased to announce the appointment of Mark Temen to fill the vacant seat on Kelso Technologies Inc's Board of Directors. Mr. Temen was nominated by shareholders and brings years of finance and business experience to the Board.

"Mark Temen's appointment contributes financial expertise to the board," says Laura Roach, Chair of the Corporate Governance and Nominating Committee. "Mr. Temen's knowledge, network, and business experience will complement the existing members and enhance board governance."

The Board and Management of Kelso Technologies Inc. welcome the addition of Mark Temen to the board. We thank Mr. Andrukaitis for his lengthy, loyal and diligent service to the company and its stakeholders, and we wish him a very happy and well-deserved retirement.
