Notes: certain items not related to "operations" of the Company's net income are listed below.

a) Non-GAAP – Flexible Solutions International purchased 65% of ENP in 4^th quarter, 2018 (October 2018). Therefore Operating Cash Flow is adjusted by the pre tax Net income or loss of the non-controlling interest in ENP for 2023 only. After 2023 the entry in the "Statement of operations and comprehensive income" is a pretax number therefore no adjustment is required.

b) Non-GAAP – amounts exclude certain cash and non-cash items: Depreciation and Stock compensation expense (2026 = $619,268, 2025 = $563,118), Interest expense (2026 = $134,069, 2025 = $198,019), Interest income (2026 = $37,446, 2025 = $49,573), (Loss) income on investment (2026 = ($54,088), 2025 = $63,925), Income tax expense (2026 = $46,681, 2025 = $110,363), and Net loss (income) attributable to non-controlling interests (2026 = $41,937, 2025 = ($13,693)). These onetime expenditures were not related to operations of FSI. *See the financial statements for all adjustments.

c) The revenue and gain from the 50% investment in the private Florida LLC announced in January 2019 are not treated as revenue or profit from operations by Flexible Solutions given the Company only purchased 50% of the LLC. The profit is treated as investment income and therefore occurs below Operating income in the Statement of Operations. As a result, the gains and losses from all investments (2026 = ($54,088), 2025 = $63,925), including those from the Florida LLC, are removed from the calculation to arrive at Operating Cash Flow.

d) Non-GAAP – amounts represent depreciation and stock compensation expense.
