Management has been able to navigate the potential negative impacts on the Company’s business model and protect the Company’s key productive assets. Kelso has prepared for growth in business activity by way of maintaining larger inventories, retaining key employees, sourcing new equity capital and continuing R&D activities to broaden out product lines. Management believes that there are significant opportunities to grow from the introduction of new innovative products in both the rail and automotive industries that are emerging from our R&D activities.

The Company continues to research, develop and engineer promising new transportation related equipment. In the heavily regulated transportation industry, the Company’s R&D projects are complex, time consuming and expensive. The primary purpose of our R&D investments is to advance and elevate the probability of future financial successes from a larger and more diverse product line. Despite the many challenges imposed by the COVID-19 recession, inflation and compromised supply chain issues Management remains bullish on the potential of all new product developments. Timing of regulatory approvals and new revenue streams remains unpredictable and certainly not guaranteed to develop at all. Management continues to assess research discoveries, new product viability, tighter budget restrictions and market potential of all of the Company’s R&D programs and adjusts strategic plans as part of the Company’s R&D risk management.

The Company has deployed capital resources sensibly to maintain financial health and liquidity during the pandemic. The Company’s balance sheet remained healthy with working capital at $8,845,629 as at March 31, 2022. Current working capital and anticipated sales activity in 2022 is expected to protect the Company’s ability to conduct ongoing business operations for the foreseeable future. With no interest-bearing long-term debt to service with broader sales prospects from a larger product portfolio, Kelso will continue to focus on stronger financial performance on behalf of the shareholders of Kelso.

The Company's method of calculating Adjusted EBITDA may differ from methods used by other issuers and, accordingly, the Company's Adjusted EBITDA may not be comparable to similar measures used by any other issuer.
