(All amounts are in thousands of Canadian dollars unless otherwise indicated)

NON-IFRS MEASUREMENTS

Cleantek uses certain financial measures to quantify its results that are not prescribed by IFRS. The following terms: "EBITDA", "adjusted EBITDA", "working capital", and "non-current debt" are not recognized measures under IFRS and may not be comparable to those reported by other companies. Cleantek believes that, in addition to measures prepared in accordance with IFRS, the non-IFRS measurements provide useful information to evaluate the Company's performance and ability to generate cash, profitability, and meet financial commitments.

These non-IFRS measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.

Adjusted EBITDA is measured as EBITDA adjusted for certain non-cash items, including share-based compensation, gains and losses on sale of assets, impact of unrealized foreign exchange gains and losses, as well as unusual items not representative of ongoing business performance, such as litigation expense and settlements, and executive severance.
