FSI ANNOUNCES SECOND QUARTER, 2025 FINANCIAL RESULTS

A CONFERENCE CALL IS SCHEDULED FOR FRIDAY, AUGUST 15, 2025, 11:00AM EASTERN TIME

SEE DIAL IN NUMBER BELOW

TABER, ALBERTA, August 14, 2025 – FLEXIBLE SOLUTIONS INTERNATIONAL, INC. (NYSE Amex: FSI), is the developer and manufacturer of biodegradable polymers for oil extraction, detergent ingredients and water treatment as well as crop nutrient availability chemistry. Flexible Solutions also manufactures biodegradable and environmentally safe water and energy conservation technologies. FSI is also increasing its presense in the food and nutrition supplement manufacturing markets. Today the Company announces financial results for second quarter ended June 30, 2025.

Mr. Daniel B. O’Brien, CEO, states, “This was an unusual quarter due to the R&D revenue which only occurs intermittently. It is also important to know that the contract announced Aug 11 was with the same company that we did the R&D with.” Mr. O’Brien continues, “Q2 had headwinds in the form of tariff increases and soft sales but the Company made strong progress toward our goal of moving our legacy production to Panama for international customers while building our food grade business in IL to serve Americans.”

The NanoChem division and ENP subsidiary continue to be the dominant sources of revenue and cash flow for the Company. Over the next several months, existing products made by NanoChem will begin production in Panama so that the new food grade products can begin production at the NanoChem plant in IL. Opportunities continue to unfold in detergent, water treatment, oil field extraction, turf, ornamental and agricultural use to further increase sales of these products. Most recently, opportunities in the food and nutrition supplement manufacturing markets have emerged.

Exhibit 99.2

Q2 2025 speech

Good morning. I’m Dan O’Brien, CEO of Flexible Solutions.

Safe Harbor provision:

The Private Securities Litigation Reform Act of 1995 provides a “Safe Harbor” for forward-looking statements. Certain of the statements contained herein, which are not historical facts, are forward looking statements with respect to events, the occurrence of which involve risks and uncertainties. These forward-looking statements may be impacted, either positively or negatively, by various factors. Information concerning potential factors that could affect the company is detailed from time to time in the company’s reports filed with the Securities and Exchange Commission.

Welcome to the FSI conference call for Q2 2025.

I would like to discuss our Company condition and our product lines first along with what we think might occur in Q3 and Q4 2025. I will comment on our financials in the second part of the speech.

NanoChem division: NCS represents approximately 70% of FSI’s revenue. This division makes thermal poly-aspartic acid, called TPA for short, a biodegradable polymer with many valuable uses. NCS also manufactures SUN 27™ and N Savr 30™ which are used to reduce nitrogen fertilizer loss from soil. In 2022, NCS started food grade operations.

TPA is used in agriculture to significantly increase crop yield. It acts by allowing the fertilizer to remain available longer for the plants to use.

TPA is a biodegradable way of treating oilfield water to prevent scale and keep oil recovery pipes from clogging.

TPA is also sold as a biodegradable ingredient in cleaning products, and as a water treatment chemical.

In our food division, a special version of TPA is sold as a wine stability aid.

SUN 27™ and N Savr 30™ are nitrogen conservation products. Nitrogen is a critical fertilizer that can be lost through bacterial breakdown, evaporation and soil runoff.

SUN 27™ is used to conserve nitrogen from attack by soil bacterial enzymes and evaporation. N Savr 30™ is effective at reducing nitrogen loss from runoff.

Food products: Our IL plant is FDA and SQF certified. We have commercialized one food product, the wine additive, based on polyaspartates that was developed fully in house.

In January, we announced a new food grade contract. In order to achieve the objectives of that contract, there are certain actions that must be completed. For example, we need to install new, specialized equipment capable of manufacturing the product.

In addition, we need to install a new “clean room” because our current clean rooms are not suitable for the processes.

There will be CAPEX associated with our efforts to earn this business because our food grade improvements over the last 2 years did not anticipate this new product category. We estimate additional CAPEX of approximately $4 million for equipment and plant improvements combined. Most of this CAPEX has been deployed already and the remainder will be spent in Q3. We have substantial cash on hand in our US subsidiaries and access to an unused LOC. There will be no equity financing needed.

CAPEX involving equipment and improvements requires lead time for delivery and installation time prior to testing leading, hopefully, to purchase orders for production. These lead times are being reduced as much as we can control and our estimate of the earliest that production could begin is Q4. After we are satisfied that we can manufacture the product at scale, and assuming that we can still meet our customer’s pricing expectations, we then hope to begin receiving purchase orders. As such, we believe that revenue could begin in Q4 and could reach significant levels by the start of 2026.

This week we announced our second major food grade contract which is from the customer we received the R&D revenue from in Q2. As noted in the news release, it is a 5-year contract with protection from tariffs and inflation. It has a minimum revenue of 6.5 MM per year and a maximum, if the customer requests it, of greater than $25 MM per year.

Production will utilize equipment we have been buying and installing over the last 2 years but had no customer for. Therefore, almost no CAPEX will be needed to reach $13 - $15 MM per year in sales and mild CAPEX in the 2-3 million range to reach $25 million. Production will begin in Q3 and revenue may be significant by Q4.

Earning these orders and hopefully growing them to the estimated maximum revenue of $30 million and $25 million per year is the critical goal for the next 4 - 6 quarters. We hope to execute this to both customers’ absolute satisfaction and obtain all their business before taking on additional major projects.

This does not mean that we are not looking for more customers as we are already doing R&D work in certain areas. However, it does mean that several quarters are likely to elapse before other major customers are found.

We would also like to be clear regarding margins in the food division. In order to obtain such large contracts from a very low base and in order to negotiate tariff and inflation protection clauses, we have lower margins than we prefer. We hope to be in the 22-25% range before tax. Future customers will be selected in order to increase our average margins now that we have a base in place.

ENP Division: ENP represents most of our other revenue. ENP is focused on sales into the greenhouse, turf and golf markets. We expect growth to continue in 2025 with the growth already apparent in early Q3

The Florida LLC investment: The LLC was profitable in Q2. The Company is focused on international agriculture sales into multiple countries. Its management has advised us that they estimate a return to growth in 2025 which should translate into increased revenue for FSI.

Agricultural products in the US are under pressure; crop prices are still not increasing at the rate of inflation and extreme uncertainty is present due to tariff changes. Growers are facing a conflict between rising costs and low crop prices, aggravated by political actions. In some cases, sales were lost for the whole season. As a result, we saw weakness in Q2 which we expect to continue in the second half.

Tariffs: The current tariff on all our imports of raw materials from China into the US is between 30% and 58.5% depending on the material. We will be very careful not to import materials unless we are sure the US customers are certain to purchase and are aware that increased tariffs will be added to their invoices once any remaining inventory is consumed. We have not managed our transition to Panama to perfection and have had to import some raw materials into the US in Q3. Some of this tariff cost will be passed to customers, some will qualify for the rebate program and some will reduce Q3 margins a small amount.

Panama factory for international sales: We are developing a duplicate agriculture and polymer facility in the Country of Panama that will be capable of producing nearly all the products we sell to international customers. We estimate that first production from this factory could begin in Q3 2025. All the equipment has arrived, raw material inventory is on hand and installation is underway. CAPEX and operational costs to develop the new plant have been funded by cash flow and retained earnings. There will be no need for debt or equity financing.

Once operational, nearly all of our products for international sale will be made in Panama using raw materials sourced without the US tariffs. There will also be advantages related to shipping; the new plant is 30 minutes from a port. Inbound raw materials and outbound finished goods will not have to be shipped across the US, to and from IL, for our international customers. Delivery times will be shortened by many days.

Reduced shipping times and no exposure to US tariffs on international sales could allow us to increase sales to existing customers and obtain new customers over the next 2 years.

Moving most agriculture and polymer production to Panama, frees space at the IL plant so that food grade production in the US can be optimized and expanded substantially as US customers are found. Panama will become a separate reporting division in our financials as soon as it begins full operation.

Shipping and Inventory: Shipping prices are stable. Shipping times are reasonable on the routes we use. No materials or finished goods transit the Red Sea.

Raw material prices are stable but increasing slowly with inflation.

Highlights of the financial results:

Sales for the quarter were up 8% compared with 2024; $11.37 MM vs $10.53 MM.

Profits: Q2 2025 recorded a profit of $2.03 million or 16 cents per share compared to a gain of $1.29 million or 10 cents per share in Q2 2024.

We recorded unusual R&D revenue in the quarter of $2.5 million which resulted in the exceptional profit. Our underlying business continued to see weakness caused by tariffs and general business uncertainty. Our agriculture sales have been reduced until the start of early buy season in Q3 and Q4.

In addition, some costs incurred to prepare for the potential new revenue from the contract announced in January negatively affected Q2 profits because they are being expensed as they occur. Some costs for the Panama factory are also being expensed quarter by quarter. This will continue in Q3 for Panama expenses and in Q3 and Q4 for food products.

Thereafter, we expect profits to revert to past levels and increase as our revenue grows.

Operating Cash Flow: This non-GAAP number is useful to show our progress especially with non-cash items removed for clarity. For first half 2025, it was $4.25 million or 34 cents per share7 up from $3.85 million or 31 cents per share in 2024.

Long-term debt: We continue to pay down our long-term debt according to the terms of the loans. The loan we used to buy our ENP division was paid in full in June this year. Our three-year note for equipment will be fully paid in December 2025. This will free up over $2 million in cash flow per year for other purposes.

Working capital is adequate for all our purposes. We have lines of credit with Stock Yards Bank for the ENP and NCS subsidiaries. We are confident that we can execute our plans with our existing capital and without resorting to any equity actions.
