Indebtedness to third parties consists of the following:

Current Credit Facility

The Company has a credit facility (“Current Credit Facility”) with Webster Bank that expires on September 30, 2026. This facility, which was entered into on December 31, 2019, was amended several times and now provides for a $20,000,000 revolving loan (“Revolving Line of Credit”), a $5,700,000 term loan and a $1,640,000 term loan (“Term Loans”). The loan is secured by a lien on substantially all of the assets of the Company.

As of March 31, 2026, there is $19,283,000 outstanding under the Revolving Line of Credit and $5,593,000 under the Term Loans.

As discussed in Note 1, the Company was in default of its minimum Fixed Charge Coverage Ratio (“FCCR”) of 1.10x as of March 31, 2026, and the Current Credit Facility expires on September 30, 2026. Therefore, the entire Term Loan and all amounts due under the Revolving Line of Credit are classified as short term as of March 31, 2026.

The below table shows the timing of payments due under the Term Loan:

Interest expense related to the Current Credit Facility amounted to approximately $379,000 and $315,000 for the three months ended March 31, 2026 and 2025, respectively. Interest expense includes the amortization of deferred finance costs of $0 and $17,000 for the three months ending March 31, 2026 and 2025, respectively.

The below summarizes various terms of the Current Credit Facility:

•        The Company is required to meet a Fixed Charge Coverage Ratio (as defined) that is determined at the end of each fiscal quarter of 1.10x. As of March 31,2026, the Company was in default with this ratio having attained a ratio of only 0.93. At December 31, 2025, the Company was in full compliance with its covenants.

The Current Credit Facility limits the amount of capital expenditures and dividends the Company can pay to its stockholders. As of March 31, 2026, the Company was in compliance with this Covenant.

Substantially all of the Company’s assets are pledged as collateral.

•        For so long as the Term Loan remains outstanding, if Excess Cash Flow (as defined) is a positive number for any fiscal year the Company shall pay an amount equal to the lesser of (i) twenty-five percent (25%) of the Excess Cash Flow for such fiscal year and (ii) the outstanding principal balance of the term loan. Such payment shall be applied to the outstanding principal balance of the Term Loan, on or prior to the April 15 immediately following such fiscal year. For the fiscal year ended December 31, 2025, based on the calculation there was no Excess Cash Flow payment required.

•        Both the Revolving Line of Credit and the Term Loan will bear an interest rate equal to the greater of (i) 3.50% and (ii) a rate per annum equal to the rate per annum published from time to time in the “Money Rates” table of the Wall Street Journal (or such other presentation within The Wall Street Journal as may be adopted hereafter for such information) as the base or prime rate for corporate loans at the nation’s largest commercial bank, less sixty-five hundredths (-0.65%) of one percent per annum. The average interest rate charged was 6.10% and 6.85% for the three months ended March 31, 2026 and 2025, respectively.

The below summarizes certain amendments to the Current Credit Facility

•        On January 30, 2025, we entered into an Eighth Amendment to provide for an additional Term Loan in the amount of $1,640,000 for the acquisition of additional equipment. The monthly principal installments on this additional Term Loan are $19,524. This amendment further revised our Financial Covenants. For the rolling twelve-month period ending March 31, 2025 and June 30, 2025, we are required to achieve a Fixed Charge Coverage Ratio of 1.05x. Beginning with the rolling twelve-month period ending September 30, 2025 and going forward the Company is required to achieve a Fixed Charge Coverage Ratio of 1.25x. Additionally, the Company is allowed to pay off up to $4,800,000 of related party notes with funds raised in the Company’s At The Market debt offering. All other covenants remain unchanged. In connection with these changes, the Company paid an amendment fee of $20,000.

•        On September 10, 2025, the Company entered into a Ninth Amendment where it agreed that $3,930,000 of the proceeds from its ATM Offering would be maintained in an interest bearing account. The funds in this account serve as additional security for its obligations under the Current Credit Facility. Additionally, this amendment waived the default as June 30, 2025.

•        On December 15, 2025, the Company entered into a Tenth Amendment which waived the defaults caused by the failure to achieve the required fixed charge coverage ratio for the fiscal quarter ended June 30, 2025, and for exceeding the permitted amount of capital expenditures for the fiscal year ending December 31, 2025. Additionally, the maturity date of the revolving credit and term loans were extended to March 31, 2026, and the capital expenditure covenant was amended. The company paid an amendment fee of $40,000.

•        On February 26, 2026, the Company entered into an Eleventh Amendment to which extended the maturity date of the revolving credit and term loans to September 30, 2026. The company paid an amendment fee of $25,000 and agreed to pay an additional fee of $150,000 on the maturity date.

As the Company is in default under the Current Credit Facility, the lender could exercise additional rights and remedies, such as increasing the rate of interest on outstanding amounts or refuse to make loans under the revolving portion of the Current Credit Facility and keep the funds remitted to the collection account. If the lender were to cease making new loans under the revolving facility or limit the amount of loans under the revolving facility, the Company would lack the funds to continue or, possibly, expand operations. To date, the lender has chosen not to exercise any of its remedies, though we agreed to put $3,930,000 of ATM proceeds in an interest bearing account to serve as additional security for the Company’s obligations under the Current Credit Facility. The Company is actively engaged in constructive discussions with various lenders as the Company has been advised by its lender that it will not renew its Current Credit Facility. While these discussions have been professional and remain ongoing, there can be no assurance that agreements will be reached with existing lenders or with alternative financing sources.

All amendment fees paid in connection with the Current Credit Facility that are for a future benefit of the Company are included in Deferred Financing Costs, Net, Deposits and Other Assets, in the accompanying consolidated balance sheets and are amortized over the term of the loan.

As of March 31, 2026, the Company has borrowing capacity of approximately $717,000 under the Revolving Loan.

If the lender were to cease making new loans under the revolving facility or limit the amount of loans under the revolving facility, the Company would lack the funds to continue or, possibly, expand operations. To date, the lender has chosen not to exercise any of its remedies, though we agreed to put $3,930,000 of ATM proceeds in an interest bearing account to serve as additional security for the Company’s obligations under the Current Credit Facility.
