Liquidity and going concern

We have incurred cumulative operating losses since inception and have a history of cash outflows from operations, inclusive of $4.5 million in cash utilized in our operating activities during the six months ended June 30, 2026. As of June 30, 2026, we had unrestricted cash on hand of $10.1 million, a working capital deficit of $7.9 million and stockholders' deficit of $30.3 million.

Second Amendment to Credit Agreement, failure to meet cash and direct tracker margin covenants and Limited Waiver

As described further in Note 11, "Debt", on March 23, 2026, we entered into a Second Amendment and Limited Waiver to our Credit Agreement (the “Second Amendment”) pursuant to which the Lenders: (i) provided a waiver relating to our breach of the purchase order covenant in our Credit Agreement for the fiscal quarter ended December 31, 2025; (ii) agreed that a purchase order covenant will not apply to us until the fiscal quarter ending March 31, 2027; and (iii) agreed to further amend certain other existing financial covenants under the Credit Agreement, including (a) a required minimum unrestricted cash covenant of $10.0 million as of September 30, 2026 and a minimum revenue covenant of $50.0 million for the quarter ended September 30, 2026. Additionally, in connection with the Second Amendment, we agreed to repay a portion of the principal amount outstanding under the Credit Agreement as follows: (x) $2.5 million of principal was repaid on March 23, 2026; (y) $2.5 million of principal was repaid on May 22, 2026; and (z) $5.0 million of principal will be repaid on September 30, 2026.

As noted above, our unrestricted cash on hand at June 30, 2026 was $10.1 million. As a result, we were not in compliance with the required minimum unrestricted cash covenant of $15.0 million pursuant to the Second Amendment as of June 30, 2026. We were also not in compliance with a required minimum direct tracker margin covenant for the three months ended June 30, 2026. On August 4, 2026, we entered into a Limited Waiver and Limited Consent to Credit Agreement (the "Waiver") with the Lenders in which the Lenders waived our noncompliance with the minimum unrestricted cash and minimum direct tracker margin covenants as described above. The Waiver covers the periods of noncompliance but does not cover our ability to comply with covenants in future periods. As a result of factors that are outside of our control in terms of timing of customer project activity and resulting revenue and cash flows, there is currently uncertainty as to our ability to fully meet all existing quarterly and annual financial covenants during the twelve-month period following the date of the consolidated financial statements included in this Quarterly Report. Accordingly, we have classified all outstanding debt under our Credit Agreement as a current obligation as of June 30, 2026. Should future actual results, including near-term operating and capital raising activities prove to be sufficient, we will reconsider the classification of our debt when appropriate.

Equity Line of Credit

As described further in Note 18, "Subsequent events" below, effective August 4, 2026, we entered into a Purchase Agreement with Lincoln Park Capital Fund, LLC (“Lincoln Park”) to establish an equity line of credit of up to $20.0 million (the “Purchase Agreement”). Pursuant to the Purchase Agreement, Lincoln Park committed to purchase, at our direction from time to time, up to an aggregate of $20.0 million of our common stock, subject to the terms, conditions and limitations set forth in the Purchase Agreement. We also entered into a registration rights agreement with Lincoln Park (the “Registration Rights Agreement”), pursuant to which we agreed to file with the SEC a registration statement covering the resale by Lincoln Park of the shares of common stock that have been and may be issued and sold to Lincoln Park under the Purchase Agreement and to take such other actions as are reasonably necessary to maintain the effectiveness of such registration statement as provided in the Registration Rights Agreement.

Payments for acquisition of Alpha Steel

On November 11, 2025, we entered into a Membership Interest Purchase Agreement with the other equity holders (the "Selling Members") of Alpha Steel LLC ("Alpha Steel") pursuant to which we agreed to acquire all of their membership interests for a purchase price of approximately $2.7 million, which was evidenced by promissory notes payable in various installments during 2026 (the "Acquisition Notes"). As of June 30, 2026, we had a remaining required payment of approximately $1.1 million due to the Selling Members, plus accrued interest, which we paid during August 2026. The Acquisition Notes were secured by all of Alpha Steel's assets, provided, however, the security interests granted to each of the Selling Members under the Acquisition Notes were subordinate and junior to the security interests in favor of the Lenders under the Credit Agreement.

Conclusion of substantial doubt

In view of the requirements for quarterly cash interest payments, a specified prepayment of principal under the Credit Agreement, and principal and interest payments for the Acquisition Notes, as well as our history of operating losses and cash outflows, and considering

that the availability of additional financing provided by the Credit Agreement in the form of Second Delayed Draw Term Loans or full utilization of the equity line of credit is not completely within our control, we believe these factors create uncertainty as to our ability to fully meet the financial covenant requirements under the Credit Agreement during the twelve months following issuance of this Quarterly Report. Therefore, we have concluded that substantial doubt exists as to our ability to continue as a going concern within the next year.

Our ability to meet our liquidity needs over the next year is dependent upon (i) our unrestricted cash on hand (subject to (x) a required principal repayment of $5.0 million on September 30, 2026, under the Credit Agreement, as well as principal and interest payments due for the Acquisition Notes, and (y) a $10.0 million minimum unrestricted cash covenant under the Credit Agreement effective for the quarter ending September 30, 2026, and each quarter thereafter, and our compliance with all other financial covenants under the Credit Agreement, (ii) our current expectations of increased project activity and cash flow during the twelve-month period following issuance of our consolidated financial statements, (iii) the availability of additional proceeds in the form of Second Delayed Draw Term Loans that may be requested by the Company, subject to approval by the Lenders in their sole discretion, and (iv) our ability to raise additional capital through the equity line of credit or other securities offerings. In addition, we continue to remain focused on implementing additional cost savings steps, which could impact, among other things, the size and location of our headcount and the level of services currently provided by third parties.

Concentration of credit risk

Financial instruments that potentially subject the Company to concentration of credit risk are primarily cash and accounts receivable.

We regularly maintain cash balances with various financial institutions that exceed federally insured amounts, but we have experienced no losses associated with these amounts to date. We periodically evaluate the financial health of the financial institutions we use and may take action in future periods, similar to past actions, to reallocate cash balances between financial institutions based on our evaluation.

We extend credit to customers in the normal course of business, often without requiring collateral. We also perform credit analyses and monitor the financial health of our customers to reduce credit risk.

The Company’s accounts receivables are derived from revenue earned from customers primarily located in the United States and Australia. For the periods included in this Quarterly Report, no company locations other than in the United States and Australia accounted for more than 10% of our consolidated revenue. Most of our customers are project developers, solar asset owners and EPC contractors that design and build solar energy projects. We typically rely on a small number of customers that account for a large portion of our revenue each period and our outstanding receivables at each period end.

Accounts receivable, net

Trade receivables are recorded at invoiced amounts, net of allowances for credit losses, and do not bear interest. We generally do not require collateral from our customers; however, in certain circumstances, we may require letters of credit, other collateral, additional guarantees or advance payments.

The allowance for credit losses is based on the lifetime expected credit loss of our customer accounts. To assess the lifetime expected credit loss, we utilize a loss rate method that takes into consideration historical experience and certain other factors, as appropriate, such as credit quality, current economic or other conditions and changes in project status that may affect a customer's ability to pay. Provisions for credit losses are included as a component of our selling and marketing expenses.

Receivables arising from revenue recognized in excess of billings represent our unconditional right to consideration before customers are invoiced due to the level of progress obtained as of period end on our contracts to procure and deliver tracker systems and related equipment. Further information may be found below in our revenue recognition policy.

Impairment

We review our long-lived assets that are held for use for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable or that its useful life may be shorter than previously expected. If such impairment indicators are present or other factors exist that indicate the carrying amount of the asset may not be recoverable, we determine whether an impairment has occurred through the use of an undiscounted cash flow analysis of the asset at the lowest level for which identifiable cash flows exist. If an impairment has occurred, we recognize a loss for the difference between the carrying amount and the fair value of the asset, which in most cases is estimated based upon Level 3 unobservable inputs. If the asset is determined to have a remaining useful life shorter than previously expected, an adjustment for the shorter remaining life will be made for purposes of recognizing future depreciation expense. Assets are classified as held for sale when we have a plan, approved by the appropriate levels of management, for disposal of such assets, as well as other considerations, and those assets are stated at the lower of carrying value or estimated fair value less estimated costs to sell.

Deferred debt discount and issue costs

Legal, consulting, accounting and other fees that are incremental and directly related to issuances of long-term debt, including any discounts on the debt, are capitalized and reflected as a reduction to the principal amount of our outstanding debt. These costs are amortized to interest expense over the term of the debt using the interest method.

Warranty

Typically, the sale of solar tracker projects includes parts warranties to customers as part of the overall price of the product. We provide standard assurance type warranties for our products for periods generally ranging from five to ten years. We also accrue for costs relating to remediation efforts involving product issues we believe require correction. We record a provision for estimated warranty and remediation expenses in cost of sales, net of amounts recoverable from manufacturers under their warranty obligations to us. When historical claims information relating to our equipment is not sufficient, we will base our estimates on industry studies involving the nature and frequency of product failure rates for similar parts used by our competitors, as well as other related businesses. We do not maintain general or unspecified reserves; all warranty reserves are related to specific projects. All actual or estimated material costs incurred for warranty or remediation services in subsequent periods are charged to those established reserves.

While we periodically monitor our warranty activities and claims, if actual costs incurred were to be different from our estimates, we would recognize adjustments to our warranty reserves in the period in which those differences arise or are identified.

Revenue recognition

Product revenue is derived from the sale of solar tracker systems and customized components for those systems, individual part sales for certain specific transactions and the sale of term-based software licenses. Term-based licensed software is deployed on the customers’ own servers and has significant standalone functionality.

Service revenue includes revenue from shipping and handling services, engineering consulting and pile testing services, our subscription-based enterprise licensing model and maintenance and support services in connection with the term-based software licenses. Our subscription-based enterprise licensing model typically has contract terms ranging from one to two years and consists of subscription fees from the licensing of subscription services. Our hosted on-demand service arrangements do not provide customers with the right to take possession of the software supporting the hosted services. Support services include ongoing security updates, upgrades, bug fixes, and maintenance.

We recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which we expect to be entitled to in exchange for those goods or services by following a five-step process: (1) identify the contract with a customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to

the performance obligations in the contract, and (5) recognize revenue when or as the Company satisfies a performance obligation, as further described below.

Identify the contract with a customer: A contract with a customer exists when (i) the Company enters into an enforceable contract with a customer that defines each party’s rights regarding the products and services to be transferred and identifies the payment terms related to these products and services, (ii) the contract has commercial substance, and (iii) the Company determines that collection of substantially all consideration for products and services that are transferred is probable based on the customer’s intent and ability to pay the promised consideration. In assessing the recognition of revenue, we also evaluate whether two or more contracts should be combined and accounted for as one contract and if the combined or single contract should be accounted for as multiple performance obligations which could change the amount of revenue and profit (loss) recorded in a period. Change orders may include changes in specifications or design, manner of performance, equipment, materials, scope of work, and/or the period of completion of the project. We analyze change orders to determine if they should be accounted for as a modification to an existing contract or a new stand-alone contract.

Contracts we enter into with our customers for sale of solar tracker systems are generally under two different types of arrangements: (1) purchase agreements and equipment supply contracts (“Purchase Agreements”), and (2) sale of individual parts for those systems.

Change orders from our customers that are deemed to be modifications to existing contracts are included in the total estimated contract revenue when it is probable that the change order will result in additional value that can be reliably estimated and realized.

Identify the performance obligations in the contract: We enter into contracts that can include various combinations of products and services, which are either capable of being distinct and accounted for as separate performance obligations or as one performance obligation since the majority of tasks and services are part of a single project or capability. However, determining whether products or services are considered distinct performance obligations that should be accounted for separately versus together may sometimes require significant judgment.

Our Purchase Agreements typically include two performance obligations: 1) our solar tracker systems or customized components of those systems, and 2) shipping and handling services. The deliverables included as part of our solar tracker systems are predominantly accounted for as one performance obligation, as these deliverables are part of a combined promise to deliver a project.

The revenue for shipping and handling services will be recognized over time based on progress in meeting shipping terms of the arrangements, as this faithfully depicts the Company’s performance in transferring control. Revenue for stand-alone engineering consulting and pile testing services is recognized at a point in time upon completion of the services performed.

Sales of individual parts of our solar tracker systems for certain specific transactions include multiple performance obligations consisting of individual parts of those systems. Revenue is recognized for parts sales at a point in time when the obligations under the terms of the contract with our customer are satisfied. Generally, this occurs with the transfer of control of the asset, which is in line with shipping terms.

Determine the transaction price: The transaction price is determined based on the consideration to which we will be entitled in exchange for transferring services to the customer. Such amounts are typically stated in the customer contract, and to the extent that we identify variable consideration, we will estimate the variable consideration at the onset of the arrangement as long as it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. Other than with respect to the impact of changes in tariff rates, the majority of our contracts do not contain variable consideration provisions as a continuation of the original contract. None of our contracts contain a significant financing component. Taxes collected from customers and remitted to governmental authorities are not included in revenue.

Allocate the transaction price to performance obligations in the contract: Once we have determined the transaction price, we allocate the total transaction price to each performance obligation in a manner depicting the amount of consideration to which we expect to be entitled in exchange for transferring the good(s) or service(s) to the customer. We allocate the transaction price to each performance obligation identified in the contract on a relative standalone selling price basis.

We use the expected cost-plus margin approach based on hardware, labor, and related overhead cost to estimate the standalone selling price of our solar tracker systems, customized components of those systems, and individual parts for certain specific transactions. We also use the expected cost-plus margin approach based on expected third-party shipping and transportation costs to estimate the standalone

selling price of our shipping, handling and logistics performance obligations. We use the adjusted market assessment approach for all other performance obligations.

Recognize revenue when or as the Company satisfies a performance obligation: For each performance obligation identified, we determine at contract inception whether we satisfy the performance obligation over time or at a point in time. The performance obligations in the contracts for our solar tracker systems and customized components of those systems are satisfied over time as work progresses, utilizing an input measure of progress determined by cost-to-cost measures on these projects as this faithfully depicts our performance in transferring control. Additionally, our performance does not create an asset with an alternative use, due to the highly customized nature of the product, and we have an enforceable right to payment for performance completed to date. Our performance obligations for individual part sales for certain specific transactions are recognized at a point in time as and when control transfers based on the terms for the contract. Our performance obligations for engineering consulting and pile testing services are recognized at a point in time upon completion of the services. Our performance obligations for term-based software licenses are recognized at a point in time as and when control transfers, either upon delivery to the customer or the software license start date, whichever is later. Our performance obligations for shipping and handling services are satisfied over time as the services are delivered over the term of the contract. We recognize revenue for subscription and other services on a straight-line basis over the contract period. With regard to support revenue, a time-elapsed method is used to measure progress because we transfer control evenly over the contractual period. Accordingly, the fixed consideration related to support revenue is generally recognized on a straight-line basis over the contract term.

Impact of changes in tariffs on our revenue recognition: In cases where our existing contracts have legally enforceable terms that allow us to pass the increased cost of tariffs to our customers automatically, any change in the transaction price will be accounted for as a change in our estimate of variable consideration and allocated to our performance obligations on the same basis as our initial allocation at contract inception. Where price changes resulting from tariffs need to be separately negotiated and agreed to with our customers, we will apply contract modification guidance once the modification is enforceable. We will also take into account tariff rates in effect at each period end in measuring our progress toward satisfaction of our performance obligations in recognizing revenue.

Contract assets and liabilities: The timing of revenue recognition, billing, and cash collection results in the recognition of accounts receivable, unbilled receivables for revenue recognized in excess of billings, and deferred revenue in the Condensed Consolidated Balance Sheets. We have elected to use the practical expedient of expensing incremental costs of obtaining a contract for our contracts of less than one year in duration. We may receive advances or deposits from our customers before revenue is recognized, resulting in contract liabilities, which are reflected as “deferred revenue” in our Condensed Consolidated Balance Sheets. Customer deposits are short term as the related performance obligations are typically fulfilled within 12 months. Changes in deferred revenue relate to fluctuations in the timing of customer deposits and completion of performance obligations. Approximately $0.5 million and $4.9 million of revenue was recognized during the three and six months ended June 30, 2026, respectively, from amounts included in deferred revenue at December 31, 2025, which totaled approximately $7.2 million. Approximately $1.2 million and $5.3 million of revenue was recognized during the three and six months ended June 30, 2025, respectively, from amounts included in deferred revenue at December 31, 2024, which totaled $5.3 million.

Cost of revenue consists primarily of costs related to raw materials, equipment manufacturing activities, net of incentives earned, freight and delivery, tariffs, product warranty, remediation and personnel costs (salaries, bonuses, benefits, and stock-based compensation). Personnel costs in cost of revenue include both direct labor costs, as well as costs attributable to any individuals whose activities relate to the procurement, installment and delivery of the finished product and services. Cost of revenue owed but not yet paid is recorded as accrued cost of revenue in the accompanying Condensed Consolidated Balance Sheets. Deferred cost of revenue, a component of our prepaid and other current assets, results from the timing differences between the costs incurred in advance of the satisfaction of all revenue recognition criteria consistent with our revenue recognition policy.

Accounting standards adopted in current period

Effective January 1, 2026, we adopted on a prospective basis Accounting Standards Update ("ASU") 2025-05, Financial Instruments - Credit Losses (Topic 326). In connection with the adoption of this new standard, we elected to utilize the practical expedient to assume that current conditions as of the balance sheet date will persist through a reasonable and supportable forecast period when adjusting historical data to be used in the estimation of credit losses. There was no material impact on the Company's financial condition or results of operations upon adoption.
