NOTE 10 – LINE OF CREDIT AND NOTES PAYABLE

On November 11, 2013, we entered into an accounts receivable financing agreement with American Interbanc (now Nations Interbanc). Amounts outstanding under the agreement bear interest at the rate of 2.5% annually. It is secured by the assets of the Company. In addition, it is personally guaranteed by Kambiz Mahdi, our Chief Executive Officer. As of March 31, 2026, the outstanding balance was $623,641 compared to $614,575 at December 31, 2025.

On April 1, 2021, we entered into an amendment to the purchase order financing agreement with DHN Capital, LLC dba Nations Interbanc. Nations Interbanc has lowered the accrued fees balance by $275,000 as well as the accrual rate to 2.25% per 30 days. As a result, CETY has agreed to remit a minimum monthly payment of $25,000 by the final calendar day of each month, The Company has not made the required monthly payments and is currently in default under the terms of the agreement.

During the year 2024, 2025, and quarter ended March 31, 2026, the Company entered into several “sale of future receipts” / merchant cash-advance arrangements with Reliance Financial FL LLC, as well as a subordinated business loan with Agile Lending, LLC and a purchase order financing facility with Nations Interbanc. Although certain Reliance contracts are legally structured as non-recourse “sales” of future business receipts, management concluded that these arrangements do not involve the transfer of discrete existing financial assets that would qualify for derecognition under ASC 860. Instead, the Company continues to generate and collect its operating cash receipts and remits amounts to the lenders until the contractual repayment amounts have been satisfied.

Accordingly, the Reliance, Agile and Nations Interbanc arrangements are accounted for as interest-bearing financing liabilities within the scope of ASC 470 and ASC 835. The Company records the net proceeds received as short-term debt and recognizes the excess of the total contractual repayment amounts (including any origination fees, daily fees and make-whole or prepayment charges) over the net proceeds as debt discounts or financing costs, which are amortized to interest expense using the simple interest method over the expected repayment periods. Legal and other third-party costs that are directly attributable to obtaining these financings are capitalized as debt issuance costs and presented as a direct deduction from the related liabilities.

Fair Value Measurements

The Company’s financial instruments consist primarily of cash, accounts receivable, accounts payable, accrued liabilities, notes payable, and derivative liabilities. The carrying amounts of cash, accounts receivable, accounts payable, and accrued liabilities approximate fair value due to their short-term maturities. The Company measures certain financial liabilities at fair value on a recurring basis. Derivative liabilities associated with certain convertible debt are measured at fair value using Level 3 inputs within the fair value hierarchy because the valuation models utilize significant unobservable inputs.
