Evaluation of Ability to Maintain Current Level of Operations  In connection with the preparation of these condensed consolidated financial statements for the three months ended June 30, 2022, management evaluated whether there were conditions and events, considered in the aggregate, that raised substantial doubt about the Company’s ability to meet its obligations as they became due over the next twelve months from the date of issuance of the Company’s first quarter of Fiscal 2023 interim condensed consolidated financial statements. Management assessed that there were such conditions and events, including a history of recurring operating losses, negative cash flows from operating activities, the continued negative impact of the volatility of the global oil and gas markets, a strong U.S. dollar in certain markets making our products more expensive in such markets, the COVID-19 pandemic, the Russian invasion of Ukraine, and ongoing global geopolitical tensions. The Company incurred a net loss of $2.1 million and used net cash in operating activities of $3.4 million for the three months ended June 30, 2022. Cash used for working capital requirements for the quarter was primarily for increased accounts payable payments to vendors during the three months ended June 30, 2022 compared to

the three months ended June 30, 2021. As of June 30, 2022, the Company had cash and cash equivalents of $16.9 million, outstanding debt of $51.0 million at fair value (see Note 10 – Term Note Payable for further discussion of the outstanding debt), and inventory purchase commitments of approximately $48.8 million through Fiscal 2023. Certain inventory delivery dates and related payments are not firmly scheduled; therefore, amounts under these firm purchase commitments will be payable upon the receipt of the related inventories and consequently may extend beyond 2023.

Management evaluated these conditions in relation to the Company’s ability to meet its obligations as they become due. The Company’s ability to continue current operations and to execute on management’s plan is dependent on the Company’s ability to generate cash flows from operations. Management believes that the Company will continue to make progress on its path to profitability through a cost reduction plan implemented in March 2022, expanding the EaaS revenue streams, as well as price increases on its Factory Protection Plan and certain product offerings. In March 2022, the Company implemented an expense reduction plan and announced its efforts to reduce operating costs and modify its operating model to better match its expanding EaaS business. In order to implement the expense reduction plan, the Company undertook a holistic review of its operations, taking the growing EaaS business into account. Beginning on February 28, 2022, the Company furloughed 17 employees for a period of 120 days, eliminated the position of Chief Revenue Officer, effective April 15, 2022, instituted 15% temporary pay cuts for approximately 36 employees and 25% temporary pay cuts for members of the Company’s senior leadership team, among other actions. The Company believes that the implementation of the expense reduction plan will help better align the Company’s current cost structure to support its higher margin EaaS revenues.

In February 2022, the Company announced that it reached its goal of having 21.1 MW of rental units in its fleet and under contract. The EaaS rental unit timeline includes a delay between the time of manufacture and the time revenue from that unit is realized. The microturbine rental unit is built, allocated by a signed rental contract, and then commissioned at the customer site, at which point it begins to generate revenue. Management expects to have all rental units contracted, commissioned, and generating revenue by the Company’s second quarter of Fiscal 2023. Management expect rental revenue to more than double in Fiscal 2023 from the $2.8 million of rental revenue in Fiscal 2022. Additionally in March 2022, the Company announced that its increased the Distributor Support System, or DSS, program fee to 5% of prior calendar year revenue, from 3%, to support the expanding EaaS business.

To help offset inflation and the rising cost of components, as well as improve our profitability, the Company implemented price increases on our Factory Protection Plan contracts effective April 1, 2022, and implemented price increases on certain of the Company’s product offerings including the C65 and C1000 products, effective May 1, 2022.

The Company may seek to raise funds by selling additional securities (through the at-the-market offering program or otherwise) to the public or to selected investors or by obtaining additional debt financing. Pursuant to the A&R NPA Second Amendment (as defined below), the Company is required to use its commercially reasonable best efforts to raise at least $10 million through a sale of common stock by September 14, 2022. There is no assurance that the Company will be able to obtain additional funds on commercially favorable terms or at all. If the Company raises additional funds by issuing additional equity or convertible debt securities, the fully diluted ownership percentages of existing stockholders will be reduced. In addition, any equity or debt securities that the Company would issue may have rights, preferences or privileges senior to those of the holders of the Company’s common stock.

Based on the current operating plan, management anticipates that, given current working capital levels and current financial projections, including the cost reduction plan, expanding EaaS business, and price increases, the Company will be able to meet its financial obligations as they become due over the next twelve months from the date of issuance of the Company’s first quarter of Fiscal 2023 interim condensed consolidated financial statements.
