KELSO TECHNOLOGIES INC. RETIREMENT OF CHIEF OPERATING OFFICER AND APPOINTMENT OF DIRECTOR

Anthony (Tony) Andrukaitis will retire from Kelso Technologies Inc.'s board of directors, effective June 3, 2025, and as chief operating officer, effective June 30, 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, Ariz., as the sixth member of the Kelso board.

Since Oct. 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," said Frank Busch, president and chief executive officer. "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, Tex., facilities, as well as the development and production of the company's rail product line. His retirement was previously delayed due to the difficult period of the COVID-19 pandemic and related rail recession. He used some of that time to mentor executive vice-president Ms. 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," said incoming COO Ms. 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, 2025, at which time she will fully assume the role of COO. As part of management's continuing 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 Mr. Temen to fill the vacant seat on Kelso'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," said 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 welcome the addition of Mr. Temen to the board. They thank Mr. Andrukaitis for his lengthy, loyal and diligent service to the company and its stakeholders, and Kelso wishes him a very happy and well-deserved retirement.
