BASIS OF PRESENTATION | 1. BASIS OF PRESENTATION These condensed interim consolidated financial statements (“consolidated financial statements”) include the accounts of Flexible Solutions International, Inc. (the “Company”), its wholly-owned subsidiaries Flexible Fermentation Ltd., NanoChem Solutions Inc. (“NanoChem”), Flexible Solutions Ltd., Flexible Biomass LP, FS Biomass Inc., NCS Deferred Corp., Natural Chem SEZC Ltd., Pana Chem Solutions Inc., InnFlex Holdings Inc., ENP Peru Investments LLC (“ENP Peru”), its 80% controlling interest in 317 Mendota LLC (“317 Mendota”), and its 65% controlling interest in ENP Investments, LLC (“ENP Investments”) and ENP Mendota, LLC (“ENP Mendota”). All inter-company balances and transactions have been eliminated upon consolidation. The Company was incorporated on May 12, 1998 in the State of Nevada and in 2019 the Company redomiciled into Alberta, Canada. In 2022, NanoChem purchased an additional 50% in ENP Peru, increasing its share to 91.67%. ENP Investments owned the remaining 8.33%, of which the Company has a 65% interest. In 2023, NanoChem purchased the remaining 8.33% of shares to become sole owner. ENP Peru was previously accounted for under the equity method however, it is now consolidated into the financial statements from the date control was obtained. In 2023, the Company purchased an 80% interest in 317 Mendota, a newly incorporated company established to purchase a large manufacturing building. ENP Investments occupies part of this building, freeing up more space in the building owned by ENP Peru for NanoChem. The remaining 20% non-controlling interest is held by unrelated parties. The manufacturing building was sold after September 30, 2025 (see Note 13). The Company and its subsidiaries develop, manufacture and market specialty chemicals which slow the evaporation of water. One product, HEATSAVR®, is marketed for use in swimming pools and spas where its use, by slowing the evaporation of water, allows the water to retain a higher temperature for a longer period of time and thereby reduces the energy required to maintain the desired temperature of the water in the pool. Another product, WATERSAVR®, is marketed for water conservation in irrigation canals, aquaculture, and reservoirs where its use slows water loss due to evaporation. In addition to the water conservation products, the Company also manufactures and markets water-soluble chemicals utilizing thermal polyaspartate biopolymers (hereinafter referred to as “TPAs”), which are beta-proteins manufactured from the common biological amino acid, L-aspartic. TPAs can be formulated to prevent corrosion and scaling in water piping within the petroleum, chemical, utility and mining industries. TPAs are also used as proteins to enhance fertilizers in improving crop yields and can be used as additives for household laundry detergents, consumer care products and pesticides. The TPA division also manufactures two nitrogen conservation products for agriculture that slows nitrogen loss from fields and has installed custom equipment used to produce food and nutritional materials. All the ingredients the Company produces are custom products for specific clients and are confidential. The Company anticipates that this market vertical will grow over time. The Company also manufactures food grade products that are made and sold by the TPA division. The TPA division recognizes research and development income from time to time.
