Our comprehensive suite of Professional Services supports solar and storage projects through every stage of the project lifecycle, offering the expertise needed to navigate complexity and scale clean energy portfolios.

Stem, Inc. was incorporated on March 16, 2009 in the State of Delaware and is headquartered in Houston, Texas.

**Liquidity**

As of March 31, 2026, we had cash and cash equivalents of $36.6 million, an accumulated deficit of $1,507.7 million, and negative working capital, which we define as current assets less current liabilities, of $16.0 million. During the three months ended March 31, 2026, we incurred a net loss of $18.9 million and had negative cash flows from operating activities of $8.3 million. As of March 31, 2026, our principal sources of liquidity were cash and cash equivalents totaling $36.6 million, which were held for working capital purposes and for investment growth opportunities. To the extent that current and anticipated future sources of liquidity are insufficient to fund our cash requirements and future business activities, we may be required to seek additional equity or debt financing. If we are unable to raise additional capital or generate cash flows necessary to expand our operations and invest in continued innovation, or pay our interest expense associated with our debt issuances, we may not be able to compete successfully, which would harm our business, operations, and financial condition. At March 31, 2026, we believe that our cash position is sufficient to meet our capital and liquidity requirements for at least the next 12 months.

On March 6, 2026, the Company entered into an open market sales agreement with Jeffries LLC (the "Agent"), as sales agent and/or principal, providing for an "at-the-market" equity offering program (the "ATM Program") pursuant to which the Company may issue and sell from time to time shares of its common stock, par value $0.0001 per share, having an aggregate offering price of up to $30.0 million (the "Shares") to or through the Agent in ordinary brokers' transactions on the NYSE or otherwise, at market prices prevailing at the time of sale, in block transactions, in negotiated transactions, in any matter permitted by applicable law or as otherwise agreed with the Agent. We intend to use any net proceeds received from the sale of the shares for general corporate purposes, including working capital. As of March 31, 2026, no shares have been issued under the ATM Program.

Our business prospects are subject to various risks, expenses and uncertainties, including those discussed in Part I. Item 1A. "Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025. The attainment of profitable operations is dependent upon future events, including continued execution of our software and services-oriented strategy, the successful delivery of AI-enabled software and edge device capabilities to our customers, securing new customers and maintaining current ones, and hiring, motivating and retaining appropriate personnel. Failure to generate sufficient revenues, achieve planned gross margins and operating profitability, control operating costs, or secure additional funding as required may require us to modify, delay or abandon some of our planned future expansion or development, or to otherwise enact additional operating cost reductions, which could have a material adverse effect on our business, operating results and financial condition.

**(UNAUDITED)**

**2.&nbsp;&nbsp;&nbsp;&nbsp;SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES** 

**Basis of Presentation**

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim reporting and with the instructions to Form 10-Q and Article 10 of Regulation S-X, assuming the Company will continue as a going concern. Accordingly, the consolidated balance sheet at December 31, 2025 has been derived from the audited financial statements at that date, but certain notes or other information that are normally required by GAAP have been omitted if they substantially duplicate the disclosures contained in the Company's annual audited consolidated financial statements. In the opinion of the Company's management, all normal and recurring adjustments considered necessary for a fair statement of the results for the interim period presented have been included in the accompanying unaudited condensed consolidated financial statements. These unaudited condensed consolidated financial statements should be read in conjunction with the Company's audited financial statements for the year ended December 31, 2025. Operating results for the three months ended March 31, 2026 are not necessarily indicative of the results that may be expected for the year ending December 31, 2026 or for any other future interim period or year.

On June 23, 2025, we effected a 1-for-20 reverse stock split, which reduced the number of our shares of common stock outstanding on that date from 167,169,140 shares to 8,358,370 shares. The number of authorized shares of our common stock has been reduced from 500.0 million shares to 250.0 million shares and the number of authorized shares of preferred stock remained unchanged at 1.0 million shares. The number of shares of common stock issuable upon settlement of outstanding restricted stock units and exercise of options was reduced proportionately as a result of the reverse stock split. Additionally, the exercise price of all outstanding options, the number of shares of common stock issuable upon the exercise of all outstanding options, and the number of shares reserved for future issuance pursuant to our equity incentive plans were all adjusted proportionately as a result of the reverse stock split. All share and per share amounts, exercise prices, conversion rates and conversion prices presented herein that relate to dates, or were established, prior to the reverse stock split have been adjusted retroactively to reflect these changes.

**Principles of Consolidation**

The unaudited condensed consolidated financial statements include the accounts of the Company, its wholly-owned subsidiaries, and consolidated variable interest entities ("VIEs"). The Company presents non-controlling interests within the equity section of its unaudited condensed consolidated balance sheets, and the amount of consolidated net loss that is attributable to the Company and the non-controlling interest in its unaudited condensed consolidated statements of operations. All intercompany balances and transactions have been eliminated in consolidation.

***Variable Interest Entities***

The Company has in some instances formed special purpose entities ("SPEs"), some of which are VIEs, with its investors in the ordinary course of business to facilitate the funding and monetization of its energy storage systems. A legal entity is considered a VIE if it has either a total equity investment that is insufficient to finance its operations without additional subordinated financial support or whose equity holders lack the characteristics of a controlling financial interest. The Company's variable interests arise from contractual, ownership, or other monetary interests in the entity. The typical condition for a controlling financial interest ownership is holding a majority of the voting interests of an entity; however, a controlling financial interest may also exist in entities, such as VIEs, through arrangements that do not involve controlling voting interests.

The Company consolidates a VIE if it is deemed to be the primary beneficiary. The Company determines it is the primary beneficiary if it has the power to direct the activities that most significantly impact the VIEs' economic performance and has the obligation to absorb losses or has the right to receive benefits of the VIE that could potentially be significant to the VIE. The Company evaluates its relationships with its VIEs on an ongoing basis to determine whether it is the primary beneficiary.

Beginning in January 2022, the Company entered into strategic joint ventures through indirect wholly-owned development subsidiaries of the Company ("DevCo JVs") with the purpose of originating potential battery storage facility projects in specific locations and conducting early-stage planning and development activities. The Company determined that the DevCo JVs are VIEs, as they lack sufficient equity to finance their activities without additional financial support. The Company determined that it has both (1) the power to direct the activities of the VIE that most significantly impact the VIE's economic performance, and (2) the obligation to absorb losses or receive benefits from the VIE that could potentially be significant. Accordingly, the Company has determined that it is the primary beneficiary of the DevCo JVs, and as a result, the DevCo JVs' operating results, assets and liabilities are consolidated by the Company, with third party minority owners' share presented as noncontrolling interest. The Company applied the hypothetical liquidation at book value method in allocating recorded net income (loss) to each owner based on the change in the reporting period, of the amount of net assets of the entity to which each owner would be entitled to under the governing contracts in a liquidation scenario.

**STEM, INC.**

**NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

**(UNAUDITED)**

The following table summarizes the carrying values of the assets and liabilities of the DevCo JVs that were consolidated by the Company as of March 31, 2026 and December 31, 2025 (in thousands):

---

| | | |
|:---|:---|:---|
| | **March 31, 2026** | **December 31, 2025** |
| **Assets** | | |
| &nbsp;&nbsp;Cash and cash equivalents | $66 | $560 |
| &nbsp;&nbsp;Account receivable | 3820 | 3820 |
| &nbsp;&nbsp;Other current assets | 300 |  |
| &nbsp;&nbsp;**Total assets** | 4186 | 4380 |
| **Liabilities** |  |  |
| &nbsp;&nbsp;Accounts payable | 203 | 440 |
| &nbsp;&nbsp;**Total liabilities** | $203 | $440 |

---

We are not making further investments in these DevCo JVs, and as of December 31, 2025 we have sold, or written off, all project assets associated with the DevCo JVs. The net income from the DevCo JVs was immaterial during the three months ended March 31, 2026 and 2025.

**Use of Estimates**

The preparation of unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. The Company bases its estimates on historical experience and on various other assumptions believed to be reasonable. Actual results could differ from those estimates and such differences could be material to the financial position and results of operations.

Significant estimates and assumptions reflected in these unaudited condensed consolidated financial statements include, but are not limited to, estimates of transaction price with variable consideration; the useful life associated with acquired intangibles; the amount of deferred commissions and contract fulfillment costs; the valuation of energy storage systems; realizability of finite-lived intangible assets; recoverability of internally developed software; accruals related to sales tax liabilities; valuation techniques used to determine gain on debt extinguishment; and the fair value of debt instruments; warrant liability and assets acquired and liabilities assumed in a business combination.

**Segment Information**

Operating segments are defined as components of an entity for which discrete financial information is available that is regularly reviewed by the Chief Operating Decision Maker ("CODM") in deciding how to allocate resources to an individual segment and in assessing performance. The Company's Chief Executive Officer is the CODM. The CODM reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. As such, management has determined that the Company operates as one operating segment that is focused exclusively on innovative technology services that transform the way energy is distributed and consumed. Net assets outside of the U.S. were less than 10% of total net assets as of March 31, 2026 and December 31, 2025.

**Accounts Receivable, Net**

Accounts Receivable are stated at amounts estimated by management to be equal to their net realizable values. Accounts receivable also includes unbilled accounts receivable, which is composed of milestone development activities of noncancellable purchase orders and monthly energy optimization services provided and recognized but not yet invoiced as of the end of the reporting period. The allowance for credit losses is the Company's best estimate of the amount of expected credit losses. The expectation of collectability is based on the Company's review of credit profiles of customers, contractual terms and conditions, current economic trends, and historical payment experience. If events or changes in circumstances indicate that specific receivable balances may be impaired, further consideration is given to the collectability of those balances and an allowance is recorded accordingly. The total allowance for credit losses balance was $3.9 million and $9.9 million, all of which is recorded against current accounts receivables as of March 31, 2026 and 2025, respectively.

------

**STEM, INC.**

**NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

**(UNAUDITED)**

The following table presents the changes in the current expected credit losses during the three months ended March 31, 2026 and 2025 (in thousands):

---

| | | |
|:---|:---|:---|
| | **March 31, 2026** | **March 31, 2025** |
| Balance as of beginning of period | $3893 | $9794 |
| Provision for expected credit losses |  | 1528 |
| Write-offs, recoveries and other charges against allowance |  | (1438) |
| Balance as of end of period | $3893 | $9884 |

---

The net book value of unbilled receivables, current are $2.5 million and $2.7 million as of March 31, 2026 and December 31, 2025, respectively. Unbilled receivables, current are included in accounts receivable, net. The net book value of unbilled receivables, noncurrent are $0.1 million and $0.1 million as of March 31, 2026 and December 31, 2025, respectively. Unbilled receivables, noncurrent are included in other noncurrent assets.

**Concentration of Credit Risk and Other Uncertainties**

Financial instruments that potentially subject the Company to concentration of credit risk consist of cash and cash equivalents and accounts receivable. The Company's cash balances are primarily invested in money market funds or on deposit at high credit quality financial institutions in the U.S. The Company's cash and cash equivalents are held at financial institutions where account balances may at times exceed federally insured limits. Management believes the Company is not exposed to significant credit risk due to the financial strength of the depository institutions in which the cash is held. The Company has no financial instruments with off-balance sheet risk of loss.

**Significant Customers**

A significant customer represents 10% or more of the Company's total revenue or accounts receivable, net balance at each reporting date. For each significant customer, revenue as a percentage of total revenue and accounts receivable as a percentage of total accounts receivable were as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Accounts Receivable** | **Accounts Receivable** | **Revenue** | **Revenue** |
| | **March 31,** | **December 31,** | **Three Months Ended March 31,** | **Three Months Ended March 31,** |
| | **2026** | **2025** | **2026** | **2025** |
| **Customers:** |  |  |  |  |
| Customer A | 12% | 17% | \* | 12% |
| Customer B | 11% | 10% | \* | \* |

---

\*Total less than 10% for the period.

There are inherent risks whenever a large percentage of total revenue is concentrated in a limited number of customers. Should a significant customer terminate or fail to renew its contracts with us, in whole or in part, for any reason, or experience significant financial or operating difficulties, it could have a material adverse effect on our financial condition and results of operations. In general, a customer that makes up a significant portion of revenues in one period, may not make up a significant portion in subsequent periods.

**Fair Value of Financial Instruments**

Assets and liabilities recorded at fair value in the unaudited condensed consolidated financial statements are categorized based upon the level of judgment associated with the inputs used to measure their fair value. The fair value of the Company's financial assets and liabilities reflects management's estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities).

Hierarchical levels which are directly related to the amount of subjectivity associated with the inputs to the valuation of these assets or liabilities are as follows:

***Level 1 —*** Unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access as of the measurement date.

------

**STEM, INC.**

**NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

**(UNAUDITED)**

***Level 2 —*** Inputs other than quoted prices included within Level 1 that are directly observable for the asset or liability or indirectly observable through corroboration with observable market data.

***Level 3 —*** Unobservable inputs for the asset or liability only used when there is little, if any, market activity for the asset or liability at the measurement date.

This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to their fair value measurement. The Company's assessment of the significance of a specific input to the fair value measurement in its entirety requires management to make judgments and consider factors specific to the asset or liability.

Financial assets and liabilities held by the Company measured at fair value on a recurring basis as of March 31, 2026 and December 31, 2025 include cash and cash equivalents and restricted cash, and warrant liability.

Assets measured at fair value on a non-recurring basis as of March 31, 2026 are assets held for sale.

**New Accounting Standards**

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40). The amendments in this update enhance disaggregated disclosure of income statement expenses for companies by requiring disaggregation of certain expense captions into specified categories in

disclosures within the footnotes to the financial statements. The effective date of ASU 2024-03 was amended by ASU 2025-01, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date. This update is effective for annual periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027, though early adoption of is permitted. The Company is currently evaluating the ASU to determine its impact on the Company's disclosures.

In September 2025, the FASB issued ASU 2025-06, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software, which clarifies and modernizes the guidance to reflect the evolution of software development from a sequential to an agile development method. The amendments in this update remove all references to project stages to reflect this change in software development and requires capitalization of software costs to begin when management has authorized and committed to funding the project and it is probable the project will be completed and used to perform the intended function. The amendments do not change what internal-use software costs can be capitalized or when such capitalization ceases. This update is effective for annual reporting periods beginning after December 15, 2027, and interim reporting periods within those annual reporting periods, though early adoption is permitted as of the beginning of an annual reporting period. The amendments may be adopted either prospectively, using a modified transition approach, or retrospectively. The Company is currently evaluating the ASU to determine its impact on the Company's disclosures.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements, which is intended to clarify interim disclosure requirements and the applicability of Accounting Standards Codification Topic 270 - Interim Reporting. The amendments create a comprehensive list of required interim disclosures and introduce a disclosure principle requiring entities to disclose, in interim periods, any event or change since the previous year-end that has a material effect on the entity. The guidance is effective for interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the ASU to determine its impact on the Company's disclosures.

**4.&nbsp;&nbsp;&nbsp;&nbsp;FAIR VALUE MEASUREMENTS**

Fair value accounting is applied for all financial assets and liabilities that are recognized or disclosed at fair value in the financial statements on a recurring basis. On March 31, 2026 and December 31, 2025, the carrying amount of accounts receivable, other current assets, accounts payable, and accrued and other current liabilities approximated their estimated fair value due to their relatively short maturities.

**Assets and Liabilities Measured at Fair Value on a Recurring Basis**

The following table provides the financial instruments measured at fair value (in thousands):

| Liabilities: |  |  |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Warrant liability | $— | $— | $5121 | $5121 |

---

The Company's money market funds are classified as Level 1 because they are valued using quoted market prices. Warrant liability is classified as Level 3 in the fair value hierarchy because its valuation is based on significant unobservable inputs, which incorporate the Company's own assumptions in valuation techniques used to determine fair value; further discussion of these assumptions is set forth below. There were no transfers into or out of Level 3 of the fair value hierarchy during the periods presented.

**Private Warrant Liability**

As discussed in Note 8 *— Warrants*, under a warrant agreement dated June 30, 2025, the Company issued 439,919 warrants (the "2030 Private Placement Warrants"), each of which entitled the holder to purchase one share of common stock at an exercise price of $30.00.

Upon issuance, these warrants met the criteria for liability classification. The fair value of the 2030 Private Placement Warrants as of March 31, 2026 was determined using the Black-Scholes-Merton model. Inputs include exercise price, volatility, fair value of common stock, expected term, expected dividend rate and risk-free interest rate.

The key assumptions used for the valuation of the private warrant liability upon remeasurement were as follows:

---

| | | |
|:---|:---|:---|
| | **March 31, 2026** | **December 31, 2025** |
| Volatility | 121.6% | 121.6% |

**2028 Convertible Notes and 2028 Capped Call Options**

***2028 Convertible Notes***

On November 22, 2021, the Company issued $460.0 million aggregate principal amount of its 2028 Convertible Notes in a private placement offering to qualified institutional buyers (the "2021 Initial Purchasers") pursuant to Rule 144A under the Securities Act of 1933, as amended.

The 2028 Convertible Notes are senior, unsecured obligations of the Company and bear interest at a rate of 0.5% per year, payable in cash semi-annually in arrears in June and December of each year. The remaining 2028 Convertible Notes will mature on December 1, 2028, unless earlier repurchased, redeemed or converted in accordance with their terms prior to such date. Upon conversion, the Company may choose to pay or deliver, as the case may be, cash, shares of its common stock or a combination of cash and shares of common stock. The 2028 Convertible Notes are redeemable for cash at the Company's option at any time given certain conditions (as discussed below). At the time of issuance, the initial conversion rate was 34.1965 shares of common stock per $1,000 principal amount of 2028 Convertible Notes, which was equivalent to an initial conversion price of approximately $29.24 per share of the Company's common stock. As a result of the reverse stock split discussed in Note 2 *— Summary of Significant Accounting Policies* under "*Basis of Presentation*", the conversion rate was adjusted to 1.7098 shares of common stock per $1,000 principal amount, which is equivalent to a conversion price of approximately $584.86 (the "2028 Conversion Price") per share of the Company's common stock. The conversion rate is subject to customary adjustments for certain events as described in the related indenture.

The Company may redeem for cash all or any portion of the 2028 Convertible Notes, at the Company's option, on or after December 5, 2025 if the last reported sale price of the Company's common stock has been at least 130% of the 2028 Conversion Price then in effect for at least 20 trading days at a redemption price equal to 100% of the principal amount of the 2028 Convertible Notes to be redeemed, plus accrued and unpaid interest.

The Company's net proceeds from this offering were approximately $445.7 million, after deducting the 2021 Initial Purchasers' discounts and debt issuance costs. To minimize the effect of potential dilution to the Company's common stockholders upon conversion of the 2028 Convertible Notes, the Company entered into separate capped call transactions (the "2028 Capped Calls") as described below. In connection with the issuance of the 2030 Convertible Notes during the second quarter of 2023, the Company used approximately $99.8 million of the net proceeds to purchase and surrender for cancellation approximately $163.0 million aggregate principal amount of the Company's 2028 Convertible Notes, which resulted in a $59.4 million gain on debt extinguishment. See 2030 Convertible Notes below for further details of the 2030 Convertible Notes. On June 30, 2025, the Company exchanged $228.8 million aggregate principal amount of the Company's 2028 Convertible Notes for a portion of the Senior Secured PIK Toggle Notes due 2030 (the "2030 Senior Secured Notes"), as part of a privately negotiated exchange agreement with holders of 2028 Convertible Notes. See *2030 Senior Secured Notes* below for further details.

Upon adoption of ASU 2020-06, the Company allocated all of the debt discount to long-term debt. The debt discount is amortized to interest expense using the effective interest method, computed to be 0.9%, over the life of the 2028 Convertible Notes or approximately its seven-year term. The outstanding 2028 Convertible Notes balances as of March 31, 2026 and December 31, 2025 are summarized in the following table (in thousands):

***2028 Capped Call Options***

On November 17, 2021, in connection with the pricing of the 2028 Convertible Notes, and on November 19, 2021, in connection with the exercise in full by the 2021 Initial Purchasers of their option to purchase additional Notes, the Company entered into the 2028 Capped Calls with certain counterparties. The Company used $66.7 million of the net proceeds from the 2028 Convertible Notes to pay the cost of the 2028 Capped Calls.

At the time of issuance, the 2028 Capped Calls had an initial strike price of $29.2428 per share, which corresponded to the initial conversion price of the 2028 Convertible Notes, and is subject to anti-dilution adjustments. The 2028 Capped Calls had an initial cap price of $49.6575 per share, subject to certain adjustments. As a result of anti-dilution adjustments arising from the reverse stock split described in Note 2 *— Summary of Significant Accounting Policies* under "*Basis of Presentation*", the strike price and cap price were adjusted to $584.856 and $993.15, respectively.

The 2028 Capped Calls are considered separate transactions entered into by and between the Company and the 2028 Capped Calls counterparties, and are not part of the terms of the 2028 Convertible Notes. The Company recorded a reduction to additional paid-in capital of $66.7 million during the year ended December 31, 2021 related to the premium payments for the 2028 Capped Calls. These instruments meet the conditions outlined in FASB ASU 2022-01 Topic 815, *Derivatives and Hedging* ("ASC 815") to be classified in stockholders' deficit and are not subsequently remeasured as long as the conditions for equity classification continue to be met.

As a result of the reverse stock split described in Note 2 *— Summary of Significant Accounting Policies* under "*Basis of Presentation*", the conversion rate was adjusted to 7.0153 shares of common stock per $1,000.00 principal amount, which is equivalent to a conversion price of approximately $142.55 (the "2030 Conversion Price") per share of the Company's common stock. The conversion rate is subject to customary adjustments for certain events as described in the related indenture.

The 2030 Convertible Notes will be redeemable, in whole or in part, at the Company's option, on or after April 5, 2027 if the last reported sale price of the Company's common stock has been at least 130% of the 2030 Conversion Price then in effect for at least 20 trading days at a redemption price equal to 100% of the principal amount of the 2030 Convertible Notes to be redeemed, plus accrued and unpaid interest.

**2030 Senior Secured Notes and 2030 Private Placement Warrants**

***2030 Senior Secured Notes***

On June 30, 2025, the Company issued $155.4 million aggregate principal amount of its 2030 Senior Secured Notes to holders of the Company's 2028 Convertible Notes and the Company's 2030 Convertible Notes in a privately negotiated exchange (the "Exchange") pursuant to Rule 144A under the Securities Act of 1933, as amended.

The transaction included an exchange of approximately (i) $228.8 million principal amount of the 2028 Convertible Notes and (ii) $121.3 million principal amount of the 2030 Convertible Notes, less amounts in lieu of fractional notes, for the 2030 Senior Secured Notes, warrants to purchase 439,919 shares of common stock (the "2030 Private Placement Warrants"), (iii) $10.0 million of cash proceeds, and accrued and unpaid interest on the exchanged 2028 Convertible Notes and 2030 Convertible Notes. The exchange resulted in a $220.0 million gain on debt extinguishment recorded within other income (expenses), net in the unaudited condensed consolidated statements of operations during the year ended December 31, 2025. The gain on debt extinguishment represented the proportional carrying value of the exchanged 2028 Convertible Notes and 2030 Convertible Notes, which in aggregate was $343.9 million, reduced by the collective fair value of the 2030 Senior Secured Notes of $132.0 million and the fair value of the 2030 Private Placement Warrants of $1.9 million, offset by cash received. The fair value of the 2030 Senior Secured Notes was estimated using a Black Derman-Toy lattice model with a yield of approximately 14.6%, synthetic credit rating for the Company, volatility of 32%, and the risk free rate of 3.79% for the expected term associated with the 2030 secured notes. The fair value of the 2030 Private Placement Warrants was estimated using the Black-Scholes-Merton model based on the Company's closing strike price on the date of extinguishment of $6.23, volatility of 118.6%, and the risk free rate of 3.79% for the expected term associated with the 2030 secured notes. The Company accrued $5.2 million in debt issuance costs primarily consisting of financial advisory, legal, and accounting fees.

At the Company's election for any interest period, the 2030 Senior Secured Notes bear interest at a rate of (i) 12.0% per year, if interest is paid in kind, subject to a maximum amount of interest able to be paid in kind, and (ii) 11.0% per year if interest is paid in cash. In each case, interest is payable semi-annually in arrears in January and July of each year, beginning on January 1, 2026. The 2030 Senior Secured Notes will mature on December 30, 2030 unless redeemed in accordance with their terms prior to such date.

The 2030 Senior Secured Notes will be redeemable, in whole or in part, for cash at the Company's option at any time, and from time to time, at the following redemption prices: on or after the date of issuance to December 31, 2027, at 105.0% of the principal amount of the notes being redeemed, including interest paid in kind, if any, plus accrued and unpaid interest; from January 1, 2028 to December 31, 2028, at 102.5% of the principal amount of the notes being redeemed, including interest paid in kind, if any, plus accrued and unpaid interest; and on or after January 1, 2029, at 100.0% of the principal amount of the notes being redeemed, including interest paid in kind, if any, plus accrued and unpaid interest.

The 2030 Senior Secured Notes are guaranteed by certain of the Company's current and future restricted subsidiaries on a senior secured basis. The 2030 Senior Secured Notes and the guarantees has been secured by a first priority lien on substantially all of the assets of the Company and the guarantors, subject to certain exceptions.

**10.&nbsp;&nbsp;&nbsp;&nbsp;NET LOSS PER SHARE**

Net loss per share is computed by dividing net loss by the basic weighted-average number of shares outstanding during the period. Diluted net loss per share is computed by dividing net loss by the diluted weighted-average number of shares outstanding during the period and, accordingly, reflects the potential dilutive effect of all issuable shares of common stock, including as a result of stock options, restricted stock units, warrants and convertible notes. The diluted weighted-average number of shares used in our diluted net loss per share calculation is determined using the treasury stock method for stock options, restricted stock units, and warrants, and the if-converted method for convertible notes. For periods in which we recognize losses, the calculation of diluted loss per share is the same as the calculation of basic loss per share.

The following table sets forth the computation of basic net loss per share and diluted net loss per share attributable to common stockholders, adjusted on a retroactive basis to reflect the reverse stock split as discussed in Note 2 *— Summary of Significant Accounting Policies* under "*Basis of Presentation*" (in thousands, except share and per share amounts):

**12.&nbsp;&nbsp;&nbsp;&nbsp;SEGMENT INFORMATION**

The Company's CODM manages the business and evaluates operating performance based on consolidated net loss. The Company's CODM uses consolidated net loss to monitor budget versus actual results. We do not allocate assets to individual business units or product lines for internal reporting purposes. Our CODM reviews the company's assets on a consolidated basis, and as a result, we do not present segment asset information separately in our consolidated financial statements. The Company operates as one operating segment and has one reporting segment that constitutes consolidated results.

The following table sets forth the Company's segment information for revenue and significant expenses (in thousands):

**13. &nbsp;&nbsp;&nbsp;&nbsp;COMMITMENTS AND CONTINGENCIES**

**Contingencies**

The Company is party to various legal proceedings from time to time arising in the ordinary course of its business. A liability is accrued when a loss is both probable and can be reasonably estimated. Management believes that the probability of a material loss with respect to any currently pending legal proceeding is remote. However, litigation is inherently uncertain and it is not possible to definitively predict the ultimate disposition of any of these proceedings. As of the date of this filing, the Company does not believe that there are any pending legal proceedings or other loss contingencies that will, either individually or in the aggregate, have a material adverse effect on the Company taken as a whole.

**Commitments**

In January 2026, the Company recognized a $2.3 million operating lease liability and a corresponding operating lease right-of use asset, which are included in the unaudited condensed consolidated balance sheets as of March 31, 2026, consisting of 15,000 square feet of office space in Gurugram, India. The Company is accounting for this office lease as an operating lease under ASC 842. As of the commencement date of the lease, the remaining lease term was 44 months and base rent is approximately $44,995 per month.

**Non-cancelable Purchase Obligations**

During the three months ended March 31, 2026, there were no material changes to our non-cancelable purchase obligations.

**Non-Income Related Taxes**

During 2023, the Company was selected for sales and use tax examination by the state of California and determined that it was not appropriately charging certain customers sales tax and remitting the applicable amounts to the taxing authority for certain revenue arrangements from 2018 through 2022. The Company determined it was probable that it would be subject to sales tax liabilities plus applicable interest in certain states, principally California, and estimated a probable tax liability of $5.6 million. The Company accrued this amount and included it in general and administrative expense in the consolidated statement of operations in 2023. During 2025, the Company accrued additional interest of $0.2 million on the unpaid tax liability, included in interest expense in the unaudited condensed consolidated statements of operations. During 2025, the sales

and use tax examination was extended by the state of California to include revenue arrangements for 2022 and 2024. The California sales and use tax examination is ongoing for the period from 2022 through 2024 and the Company is awaiting final ruling on its sales tax administration process and clarity on the required settlement amount.

**14. &nbsp;&nbsp;&nbsp;&nbsp;SUBSEQUENT EVENTS**

On April 23, 2026, the Company acquired 100% of the outstanding shares of raicoon GmbH ("raicoon"). raicoon is a Vienna-based software company focused on automated fault detection and event management for solar asset performance. The total consideration to acquire raicoon was $4.3 million in the form of 389,569 shares of the Company's common stock.

The initial accounting for this acquisition is incomplete at the time of issuance of these unaudited condensed consolidated financial statements. Consequently, the Company cannot disclose the fair values of the acquired intangible assets and the related deferred tax liabilities. The appraisal of the acquired intellectual property is ongoing. The Company expects to finalize the purchase price allocation, including the recognition of goodwill, in the second quarter of 2026.

Since our inception in 2009, we have engaged in developing and marketing AI-enabled software and services, raising capital, recruiting personnel, and growing our annual recurring revenue. Over the last 15 years, we have been an industry leader in clean energy software and solutions.

Each year since our inception, we have incurred net operating losses. We have financed our operations primarily through cash flows from customers and the issuance of convertible senior notes.

Our total revenue decreased from $32.5 million for the three months ended March 31, 2025 to $29.0 million for the three months ended March 31, 2026. For the three months ended March 31, 2026 and 2025, we incurred a net loss of $18.9 million and $25.0 million, respectively. As of March 31, 2026, we had an accumulated deficit of $1,507.7 million.

**Key Factors, Trends and Uncertainties Affecting our Business**

We believe that our performance and future success depend on several factors, some of which present significant opportunities for us, and some of which pose risks and challenges, including but not limited to:

***Our Strategy***

In 2024, we announced a new business strategy that reflects a renewed focus on developing and marketing our AI-enabled software, edge and services offerings. This transition has entailed significant operational changes during calendar years 2024 and 2025, including reduction of what had historically been the source of most of our revenue (battery resales), adjustments to the way we develop and market our products and services, and realignment of our business processes. These changes have resulted in reduced revenue, increased restructuring-related costs, reduced operating expenses, and short-term disruptions in our operations, which may negatively affect our ability to effectively scale our software and services offerings and achieve our financial and operational targets. Failure to achieve the anticipated benefits of our strategy may have a material adverse effect on our business, financial condition, and results of operations. See *"Our strategy may not achieve anticipated benefits."* in Part I. Item 1A. "Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025 for additional information about some risks related to our strategy.

***Cash Reserves***

The execution of our business strategy has required, and is expected to continue to require, investment in our software, our employees and infrastructure. As of March 31, 2026, we had cash and cash equivalents of $36.6 million, while our operating expenses for the three months ended March 31, 2026 were $25.1 million. If our cash flow from operations does not improve as expected, or if we are unable to secure additional sources of capital if or when the need arises, we may be constrained in our ability to make the investments required to continue execution of our new strategy.

------

***Reverse Stock Split***

On August 28, 2024, we received formal notice from the New York Stock Exchange (the "NYSE") that we were not in compliance with Section 802.01C of the NYSE Listed Company Manual because the average closing price of our shares of common stock had fallen below $1.00 per share over a period of 30 consecutive trading days.

At the Company's 2025 Annual Meeting of Stockholders, our stockholders approved a reverse stock split of our common stock, par value $0.0001 per share. After such stockholder approval, our Board of Directors implemented the reverse stock split at a ratio of 1-for-20 and a reduction in the total number of authorized shares of common stock from 500.0 million shares to 250.0 million shares on June 23, 2025 (the "Effective Time").

At the Effective Time, every 20 shares of common stock outstanding was combined, automatically and without any action on the part of the Company or its stockholders, into one new share of common stock. No fractional shares of common stock were issued as a result of the reverse stock split. In lieu of any fractional shares to which a stockholder of record was otherwise entitled, the Company paid cash to the applicable stockholder. The common stock began trading on a split-adjusted basis at the open of trading on June 23, 2025.

Adjustments proportionate to the 1-for-20 split ratio were made to the number of shares of Common Stock available for issuance under the Company's equity incentive plans; the number of shares issuable, and the applicable exercise prices under the Company's outstanding equity awards under such plans and any outstanding warrants; the conversion rates of outstanding convertible notes, in accordance with the related indentures; the strike prices of existing capped call options; the number of shares authorized for issuance pursuant to the convertible notes and capped call options; the shares reserved for issuance under any equity plan, outstanding equity award, convertible notes, capped call options or otherwise, and as otherwise described in the Company's Definitive Proxy Statement filed with the Securities and Exchange Commission on April 23, 2025.

Following the Effective Time, we regained compliance with the requirement of Section 802.01C, as our share price promptly exceeded $1.00 per share, and remained above that level for the following 30 trading days.

All share and per share amounts, exercise prices, conversion rates and conversion prices presented herein that relate to dates, or were established, prior to the reverse stock split have been adjusted retroactively to reflect these changes.

***One Big Beautiful Bill Act of 2025***

In July 2025, the OBBB was enacted, which introduced material changes to clean energy tax credit programs that are significant to our business and may affect our financial condition, results of operations and future prospects. Included in this legislation are provisions that allow for the immediate expensing of domestic United States research and development expenses, immediate expensing of certain capital expenditures, and other changes to the U.S. taxation of profits derived from foreign operations. The OBBB did not result in any material changes to tax expense or cash tax for 2025, primarily as a result of the valuation allowance we have on our deferred tax assets.

The OBBB scales back the Investment Tax Credit (the "ITC") available under Section 25D of the Internal Revenue Code (the "Code") for residential solar and storage systems purchased through cash or loans. Under the OBBB, the Section 25D credit expired on December 31, 2025. In addition, the OBBB imposes new timing requirements for eligibility under Section 48E of the Code, which governs ITCs for leased solar and storage systems. Previously under the IRA, Section 48E credits were available through 2032 or such later period when the U.S. power sector emitted 75% less carbon emissions than 2022 levels. Under the OBBB, these credits will no longer be available for solar-only projects placed in service after December 31, 2027, unless construction begins on or before July 4, 2026, pursuant to a grandfathering rule. Projects that qualify under this rule must still meet continuity requirements to remain eligible. Energy storage projects are not subject to this placed-in-service deadline; however, the ITC for storage systems will begin to phase down in 2034 - decreasing to 75% in 2034, 50% in 2035 and phasing out entirely by 2036.

The OBBB also amends the domestic content bonus credit rules for Section 48E projects. Projects commencing construction after June 16, 2025 and before January 1, 2026 must meet a 45% domestic cost threshold. If construction begins in 2026, the project's domestic cost threshold is 50%, and if construction begins after 2026, the project's domestic cost threshold is 55%.

Additionally, the OBBB introduces new compliance requirements under the Foreign Entity of Concern ("FEOC") provisions for both Section 48E and the Advanced Manufacturing Production Tax Credit ("AMPTC") under Section 45X. These provisions limit "material assistance" from FEOCs in projects otherwise eligible for tax credits under Section 48E and Section 45X and establish an escalating threshold of non-FEOC content that must be met by solar and storage projects beginning construction in 2026 and by manufactured components produced beginning in 2026.

On July 7, 2025, the President issued an Executive Order directing the Secretary of the Treasury to issue updated guidance on the "beginning of construction" requirements applicable to Section 48E projects under the OBBB and also to implement the FEOC restrictions set forth in the OBBB. On August 15, 2025, the Treasury Department released Notice 2025-42, which modifies the rules for determining when construction begins for purposes of qualifying for the Section 48E credits. The

------

guidance eliminates the longstanding 5 percent safe harbor for solar projects larger than 1.5 megawatts (AC), effective for projects that begin construction on or after September 2, 2025. Projects that began construction prior to that date continue to be governed by prior IRS guidance. The 5 percent safe harbor remains available for solar facilities of 1.5 MW or smaller. Under the new rules, the physical work test is now the sole method for establishing that construction has begun for affected solar projects larger than 1.5 MW and for all wind projects. The test requires that "physical work of a significant nature" be performed, without regard to cost, and may include certain on-site and off-site activities but excludes preliminary activities such as planning, permitting, and financing. We are currently evaluating the full impact of this legislation on our consolidated financial statements.

The OBBB makes permanent key elements of the Tax Cuts and Jobs Act, including 100% bonus depreciation, domestic research cost expensing, and the business interest expense limitation. ASC 740, "Income Taxes", requires the effects of changes in tax rates and laws to be recognized in the period in which the legislation is enacted, which is the date the legislation is signed into law. The OBBB did not have a material impact on our financial statements for 2025, but we continue to evaluate the potential future impact of the OBBB on our financial statements.

***Seasonality***

Our results of operations have typically fluctuated due to seasonal trends, which we expect to recur in future periods. Historically, we have recognized more of our revenue in the third and fourth fiscal quarters of each year due to various factors, including the requirement by our customers to reach target commercial operation dates for their renewable energy projects as well as tax equity and financing considerations. For instance, our revenue recognized in the third and fourth quarters of the fiscal year ended December 31, 2025 accounted for 55% of the total revenue recognized in the fiscal year ended December 31, 2025. The seasonality of our results of operations may be mitigated as our software and services offerings begin to comprise a greater percentage of our total revenue.

***DevCo Joint Ventures***

We, through an indirect wholly-owned development subsidiary, entered into strategic joint ventures with qualified third parties to develop select energy storage generation projects ("DevCo Projects"), as more fully described above under Note 2 *— Summary of Significant Accounting Policies*, of the Notes to the unaudited condensed consolidated financial statements in this report. We have not made an investment in any DevCo Project since 2024, and we are not making further investments in these DevCo Projects. As of December 31, 2025 we have sold, or written off, all project assets associated with the DevCo Projects.

***Increase in Deployment of Renewables***

Deployment of intermittent resources has accelerated over the last decade, and today, wind and solar have become a low cost energy source. We expect the cost of generating renewable energy to continue to decline and deployments of energy storage systems to increase. As renewable energy sources of energy production are expected to represent a larger proportion of energy generation, grid instability rises due to their intermittency, which can be addressed by energy storage solutions.

***Competition***

Our key competitors include energy monitoring and optimization software providers, energy storage and edge device OEMs and hardware integration providers. Our PowerTrack software is hardware agnostic and benefits from operational data across a multitude of hardware types, geographies, utilities and grid operator service areas. Our edge devices provide customers with a flexible solution that meets their individual project needs.

We believe we are well-positioned to compete successfully in the market for software and software-enabled services. We are among the leaders in global distributed solar and energy storage assets under management, supported by proven technology, focused customer service, strong strategic partnerships and a seasoned leadership team with a track record of success.

Existing competitors may expand their product offerings and sales strategies, and new competitors may enter the market. Furthermore, our competitors include other types of software providers and some hardware manufacturers that offer software solutions. If our market share declines due to increased competition, our revenue and ability to generate profits in the future may be adversely affected.

***Government Regulation and Compliance***

Although we are not regulated as a utility, the market for our products and services is heavily influenced by federal, state, and local government statutes and regulations concerning electricity. These statutes and regulations affect electricity pricing, net metering, incentives, taxation, competition with utilities, and the interconnection of customer-owned electricity generation. In the United States and internationally, governments regularly modify these statutes and regulations and acting through state utility or public service commissions, regularly change and adopt different rates for commercial customers. These changes can positively or negatively affect our ability to deliver cost savings to customers.

------

**Non-GAAP Financial Measures**

In addition to financial results determined in accordance with U.S. generally accepted accounting principles ("GAAP"), we use adjusted EBITDA and non-GAAP gross profit and margin, which are non-GAAP financial measures, for financial and operational decision making and as a means to evaluate our operating performance and prospects, develop internal budgets and financial goals, and to facilitate period-to-period comparisons. Our management believes that these non-GAAP financial measures provide meaningful supplemental information regarding our performance by excluding certain expenses and expenditures that may not be indicative of our operating performance, such as stock-based compensation and other non-cash charges, as well as discrete cash charges that are infrequent in nature. We believe that both management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting, and analyzing future periods. These non-GAAP financial measures also facilitate management's internal comparisons to our historical performance as well as comparisons to our competitors' operating results. We believe these non-GAAP financial measures are useful to investors because they both (1) allow for greater transparency with respect to key metrics used by management in its financial and operational decision making and (2) are used by our institutional investors and the analyst community to help them analyze the health of our business. Adjusted EBITDA and non-GAAP gross profit and margin should be considered in addition to, not as a substitute for, or superior to, other measures of financial performance prepared in accordance with GAAP.

***Non-GAAP Gross Profit and Margin***

We define non-GAAP gross profit as gross profit excluding amortization of capitalized software, and impairments related to decommissioning of end-of-life systems. We define non-GAAP gross margin as non-GAAP gross profit as a percentage of revenue.

***Adjusted EBITDA***

As discussed above, we believe that adjusted EBITDA is useful for investors to use in comparing our financial performance with the performance of other companies. Nonetheless, the expenses and other items that we exclude in our calculation of adjusted EBITDA may differ from the expenses and other items, if any, that other companies may exclude when calculating adjusted EBITDA.

We calculate adjusted EBITDA as net loss attributable to us before depreciation and amortization, including amortization of internally developed software, interest expense, further adjusted to exclude stock-based compensation and other income and expense items, including change in fair value of warrant liability, impairment of assets held for sale and income tax provision or benefit.

The following table provides a reconciliation of adjusted EBITDA to net loss (in thousands):

***Bookings***

Due to the long-term nature of our contracts, bookings are a key metric that allows us to understand and evaluate the growth of our Company and our estimated future revenue related to customer contracts for our energy optimization services, sales of energy storage systems, asset monitoring software, edge devices, and project and professional service engagements. Bookings represent the total value of executed customer purchase orders. Customer purchase orders are typically executed three to six months ahead of hardware installation. The booking amount includes (1) hardware revenue, which is typically recognized at delivery of the energy storage system and/or edge device to the customer, and (2) services revenue, which represents the total nominal software and services contract value which will be recognized ratably over the contract period.

**Components of Our Results of Operations**

***Revenue***

We generate services and other revenue and hardware revenue. Services and other revenue is generated through (i) energy optimization software (ii) asset management software, and (iii) advisory services and (iv) the sale of project assets. Software fees charged to customers generally consist of recurring fixed monthly payments throughout the term of the contract and in some arrangements, an installation and/or upfront fee component. We may also receive incentives from utility companies in relation to the sale of our services.

------

We generate hardware revenue through (i) edge hardware devices and (ii) sales of OEM energy storage systems. Performance obligations are satisfied when the energy storage system and edge hardware device along with all ancillary hardware components are delivered. The milestone payments received before the delivery of hardware are treated as deferred revenue. In certain customer contracts, we agreed to provide a guarantee that the value of purchased hardware will not decline for a certain period of time, as more fully described below under Note 3 — *Revenue*, of the Notes to the unaudited condensed consolidated financial statements in this Report.

***Cost of Revenue***

Cost of services and other revenue primarily includes costs to service our storage and solar subscription customers. It includes expenses related to providing support to our customers and cloud-related costs, such as hosting costs. These costs primarily consist of personnel-related expenses of our services and customer support personnel, amortization of capitalized internal-use software development, and public cloud and cellular infrastructure costs. Cost of services and other revenue also includes depreciation of the cost of energy storage systems we own under long-term customer contracts, which includes capitalized fulfillment costs, such as installation services, permitting and other related costs. Additionally, cost of services and other revenue may include the costs for the development and constructions of project assets or any impairment of inventory and energy storage systems, along with system maintenance costs associated with the ongoing services provided to customers.

Cost of hardware revenue generally includes the cost to produce edge hardware and the battery hardware purchased from a manufacturer, shipping, delivery, and other costs required to fulfill our obligation to deliver the edge hardware and energy storage systems to the customer location. Cost of hardware revenue may also include any impairment of energy storage systems held in our inventory for sale to our customer. Cost of hardware revenue related to the sale of energy storage systems is recognized when the delivery of the product is completed.

***Gross Profit***

Our gross profit is subject to fluctuation from quarter to quarter. Gross profit, calculated as revenue less costs of revenue, has been, and will continue to be, affected by various factors, including fluctuations in the amount and mix of revenue and the amount and timing of investments to expand our customer base. Over the long term, we hope to increase both our gross profit in absolute dollars and gross margin as a percentage of revenue through enhanced operational efficiency and economies of scale.

***Operating Expenses***

*Sales and Marketing*

Sales and marketing expense consists of payroll and other related personnel costs, including salaries, stock-based compensation, commissions, bonuses, employee benefits, and travel for our sales and marketing personnel. In addition, sales and marketing expense includes trade show costs, amortization of intangibles and other expenses. We expect our sales and marketing expense to increase in future periods to support the overall growth in our business.

*Research and Development*

Research and development expense consists primarily of payroll and other related personnel costs for engineers and third parties engaged in the design and development of products, third-party software and technologies, including salaries, bonuses and stock-based compensation expense, project material costs, services and depreciation. Our research and development expenses support our investments in optimization, accuracy and reliability of our platform and other technology improvements to support and drive efficiency in our operations. These expenses may vary from period to period as a percentage of revenue, depending primarily upon when we choose to make more significant investments.

*General and Administrative*

General and administrative expense consists of payroll and other related personnel costs, including salaries, stock-based compensation, employee benefits and expenses for executive management, legal, finance, human resources and other costs. In addition, general and administrative expense includes fees for professional services and occupancy costs. We expect to continue to manage and reduce our general and administrative expense associated with scaling our business operations and being a public company, including compliance with the rules and regulations of the SEC, legal, audit, additional insurance expenses, investor relations activities, and other administrative and professional services.

*Impairment of Assets Held for Sale*

Impairment of assets held for sale represents impairment charges as a result of the carrying amount being greater than the fair value of the assets held for sale.

------

***Other Expense, Net***

*Interest Expense*

Interest expense consists primarily of interest on our convertible senior notes, and financing obligations and accretion on our asset retirement obligations.

*Change in Fair Value of Warrant Liability*

Change in fair value of warrant liability is related to the revaluation at each reporting date of our private placement warrants issued in connection with our senior secured notes.

*Other Income, Net*

Other income, net consists primarily of income from interest, equity investments and foreign exchange gains or losses.

\*Percentage is not meaningful

***Revenue***

Revenue decreased by $3.5 million, or 11%, for the three months ended March 31, 2026, as compared to the three months ended March 31, 2025. The decrease was primarily driven by a $4.5 million decrease in hardware revenue that is primarily the result of a decrease in battery hardware resales being offset by increased edge hardware and service offerings as the Company continues to strategically de-emphasize battery hardware resales and pursue more selective opportunities. Service and other revenue also increased $1.0 million, primarily due to an increase in solar services subscriptions from existing and new customers.

***Cost of Revenue***

Cost of revenue decreased by $3.8 million, or 17%, for the three months ended March 31, 2026, as compared to the three months ended March 31, 2025. The decrease was primarily driven by a decrease in cost of hardware revenue of $4.4 million primarily due to a reduction in low margin battery hardware resales as the company continues to strategically de-emphasize this business line and pursue more selective opportunities. This decrease was partially offset by an increase in cost of services and other revenue of $0.5 million primarily due to higher cloud infrastructure costs to support our growing PowerTrack software platform.

------

***Operating Expenses***

*Sales and Marketing*

Sales and marketing expense decreased by $0.3 million, or 4%, for the three months ended March 31, 2026, as compared to the three months ended March 31, 2025. The decrease was driven by a decrease of $0.3 million in personnel related expenses due to a decrease in headcount.

*Research and Development*

Research and development expense decreased by $4.8 million, or 42%, for the three months ended March 31, 2026, as compared to the three months ended March 31, 2025. The decrease was primarily due to a decrease of $3.7 million in personnel related expenses as a result of lower headcount, and a decrease of $1.1 million in professional services and other expenses.

*General and Administrative*

General and administrative expense decreased by $4.9 million, or 36%, for the three months ended March 31, 2026, as compared to the three months ended March 31, 2025. The decrease was primarily driven by a decrease of $2.3 million in personnel related expenses driven by a decrease in headcount, a decrease of $1.5 million in office-related and other expenses, and a decrease of $1.1 million in professional services, resulting from decreases in advisory services.

*Impairment of Assets Held for Sale*

During the three months ended March 31, 2026, we recorded impairment of $3.3 million on assets held for sale as the carrying amount of the assets held for sale exceeded its fair value.

***Other Expense, Net***

*Interest Expense, Net*

Interest expense, net increased by $3.1 million, or 72%, for the three months ended March 31, 2026, as compared to the three months ended March 31, 2025. The increase was primarily driven by an increase of $3.4 million in interest on notes, partially offset by a decrease of $0.3 million in interest on financing obligations.

*Change in Fair Value of Warrant Liability*

During the three months ended March 31, 2026, we recorded a gain on remeasurement of $2.4 million relating to our private placement warrants issued in June 2025.

*Other Income, Net*

Other income, net decreased by $0.1 million, or 30%, for the three months ended March 31, 2026, as compared to the three months ended March 31, 2025 primarily due to a $0.3 million decrease in interest income from short-term investments, partially offset by a $0.1 million increase in income from equity investments and a $0.1 million increase in other income.

***Provision for Income Taxes***

During the three months ended March 31, 2026, we recorded a provision for income taxes of $0.1 million primarily as a result of foreign and state income tax expense. During the three months ended March 31, 2025, we recorded a $0.1 million provision for income taxes primarily as a result of foreign income tax expense.

**Liquidity and Capital Resources**

***Sources of Liquidity***

Liquidity describes the ability of a company to generate sufficient cash flows to meet the cash requirements of its business operations, including working capital needs, debt service, acquisitions, contractual obligations and other commitments. We assess liquidity in terms of our cash flows from operations and their sufficiency to fund our operating and investing activities. To meet our payment service obligations, we must have sufficient liquid assets and be able to move funds on a timely basis. Significant factors in the management of liquidity are funds generated from operations, levels of accounts receivable and accounts payable and capital expenditures.

As of March 31, 2026, our principal sources of liquidity were cash and cash equivalents of $36.6 million, which were held for working capital purposes and for investment growth opportunities. As of March 31, 2026, our working capital (deficit), which we define as current assets less current liabilities, was a deficit of $16.0 million. We believe that our cash position is sufficient to meet our capital and liquidity requirements for at least the next 12 months.

------

Our attainment of profitable operations is dependent upon future events, including continued implementation of our new business strategy, hiring and retaining our key executives and personnel with the requisite experience to develop our software and AI-based solutions, controlling our operating costs and building our customer base. Failure to successfully implement our new business strategy, generate sufficient revenues from our software and services offerings, achieve planned gross margins and operating profitability, control operating costs, or secure additional funding may require us to modify, delay, or abandon some of our planned future expansion or development, or to otherwise enact operating cost reductions available to management, which could have a material adverse effect on our business, operating results, and financial condition. The execution of our new strategy has required significant operational changes, including reduction of what has historically been the source of most of our revenue (battery resales), adjustments to the way we develop and market our products and services, and realignment of our business processes. These changes have resulted in reduced revenue, increased costs and short-term disruptions in our operations, which have negatively impacted our financial condition in the near term. Furthermore, our cash reserves may constrain our ability to make the investments required to execute our new strategy or may otherwise not be sufficient to fund operations. If our cash flow from operations does not improve as quickly as expected, or if we are unable to secure additional sources of capital if or when the need arises, it may have a material adverse effect on our business, financial condition, and results of operations.

To the extent that current and anticipated future sources of liquidity are insufficient to fund our cash requirements and future business activities, we may be required to obtain additional equity or debt financing, which may not be available on terms acceptable to us or at all. If we are unable to raise additional capital or generate cash flows necessary to expand our operations and invest in new technologies, or pay our interest expense associated with our debt issuances, this could reduce our ability to compete successfully, which would harm our business operations and financial condition.

Our long-term liquidity requirements are linked primarily to the expansion of our software and services offerings and our related business strategy, as well as the continued extension of PowerTrack<sup>TM</sup> and other software applications. While we have plans to potentially expand our geographical footprint beyond our current partnerships and enter into joint ventures, those are not required initiatives to achieve our plans.

***Financing Obligations***

We have entered into arrangements wherein we finance the cost of energy storage systems via special purpose entities ("SPEs") we establish with outside investors. These SPEs are not consolidated into our financial statements, but are accounted for as equity method investments. The investors provide us upfront payments through the SPEs. Under these arrangements, the payment by the SPEs to us is accounted for as a borrowing by recording the proceeds received as a financing obligation. The financing obligation is repaid with the future customer payments and incentives received. A portion of the amounts paid to the SPE is allocated to interest expense using the effective interest rate method. Furthermore, we continue to account for the revenues from customer arrangements and incentives and all associated costs despite such systems being legally sold to the SPEs due to our significant continuing involvement in the operations of the energy storage systems. The total financing obligation as of March 31, 2026 was $39.9 million, of which $13.2 million was classified as a current liability.

***2028 Green Convertible Senior Notes***

On November 22, 2021, we sold to Morgan Stanley & Co. LLC, Goldman Sachs & Co. LLC and Barclays Capital Inc, as initial purchasers (the "2021 Initial Purchasers"), and the 2021 Initial Purchasers purchased from us, $460.0 million aggregate principal amount of our 0.50% Green Convertible Notes due 2028 (the "2028 Convertible Notes'), pursuant to a purchase agreement dated as of November 17, 2021, by and between us and the 2021 Initial Purchasers. Our net proceeds from this offering were approximately $445.7 million, after deducting the 2021 Initial Purchasers' discounts and commissions and the estimated offering expenses payable by us. The 2028 Convertible Notes accrue interest payable semi-annually in arrears and will mature on December 1, 2028, unless earlier repurchased, redeemed or converted in accordance with their terms prior to such date. Upon conversion, we may choose to pay or deliver, as the case may be, cash, shares of common stock or a combination of cash and shares of common stock. The 2028 Convertible Notes are redeemable for cash at our option at any time given certain conditions. Refer to Note 7 — *Debt*, of the Notes to the unaudited condensed consolidated financial statements in this Report for additional details regarding this transaction.

On November 17, 2021, in connection with the pricing of the 2028 Convertible Notes, and on November 19, 2021, in connection with the exercise in full by the 2021 Initial Purchasers of their option to purchase additional 2028 Convertible Notes, we entered into capped call transactions with certain of the 2021 Initial Purchasers of the 2028 Convertible Notes to minimize the potential dilution to our common stockholders upon conversion of the 2028 Convertible Notes. We used approximately $66.7 million of the net proceeds from the 2028 Convertible Notes to pay the cost of the capped call transactions described above. We intend to allocate an amount equivalent to the net proceeds from this offering to finance or refinance, in whole or in part, our existing or new eligible green expenditures, including investments related to creating a more resilient clean energy system, optimized software capabilities for energy systems, and reducing waste through operations.

------

On April 3, 2023, we used approximately $99.8 million of the net proceeds from the issuance of the 4.25% Green Convertible Senior Notes due 2030 ("2030 Convertible Notes") to purchase and surrender for cancellation approximately $163.0 million in aggregate principal amount of our 2028 Convertible Notes. See Note 7 *— Debt,* of the Notes to the unaudited condensed consolidated financial statements in this Report for additional details regarding this transaction.

On June 30, 2025, we exchanged approximately $228.8 million aggregate principal amount of the Company's 2028 Convertible Notes and approximately $121.3 million aggregate principal amount of the Company's 2030 Convertible Notes, for a portion of the Senior Secured PIK Toggle Notes due 2030 (the "2030 Senior Secured Notes"), which resulted in a $220.0 million gain on debt extinguishment. See Note 7 *— Debt*, of the Notes to the unaudited condensed consolidated financial statements in this Report, for additional details regarding this transaction.

We or our affiliates may, at any time and from time to time, seek to retire or purchase our outstanding 2028 Convertible Notes through cash purchases and/or exchanges for equity or debt, in open-market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will be upon such terms and at such prices as we may determine, and will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

***2030 Convertible Notes***

On April 3, 2023, we issued $240.0 million aggregate principal amount of our 2030 Convertible Notes in a private placement offering to qualified institutional buyers (the "2023 Initial Purchasers") pursuant to Rule 144A under the Securities Act of 1933, as amended. The 2030 Convertible Notes are senior, unsecured obligations of the Company and bear interest at a rate of 4.25% per year, payable in cash semi-annually in arrears in April and October of each year, beginning in October 1, 2023. The 2030 Convertible Notes will mature on April 1, 2030, unless earlier repurchased, redeemed or converted in accordance with their terms prior to such date. Upon conversion, we may choose to pay or deliver cash, shares of common stock or a combination of cash and shares of common stock. The 2030 Convertible Notes are redeemable for cash at our option at any time given certain conditions. See Note 7 *— Debt*, of the Notes to the unaudited condensed consolidated financial statements in this Report, for additional details regarding this transaction.

Our net proceeds from this offering were approximately $232.4 million, after deducting for $7.6 million of debt issuance costs primarily consisting of underwriters, advisory, legal, and accounting fees. We used approximately $99.8 million of the net proceeds to purchase and surrender for cancellation approximately $163.0 million aggregate principal amount of our 2028 Convertible Notes.

On March 29, 2023 and March 31, 2023, in connection with the pricing of the 2030 Convertible Notes, and on April 3, 2023, in connection with the exercise in full by the 2023 Initial Purchasers of their option to purchase additional 2030 Convertible Notes, we entered into capped calls (the "2030 Capped Calls") with certain counterparties. We used $27.8 million of the net proceeds from the 2030 Convertible Notes to pay the cost of the 2030 Capped Calls.

On June 30, 2025, we exchanged approximately $121.3 million aggregate principal amount of the Company's 2030 Convertible Notes, for a portion of the new 2030 Senior Secured Notes, which resulted in a $220.0 million gain on debt extinguishment. See Note 7 *— Debt*, of the Notes to the unaudited condensed consolidated financial statements in this Report, for additional details regarding this transaction.

We or our affiliates may, at any time and from time to time, seek to retire or purchase our outstanding 2030 Convertible Notes through cash purchases and/or exchanges for equity or debt, in open-market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will be upon such terms and at such prices as we may determine, and will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.

On June 30, 2025, the Company issued $155.4 million in aggregate principal amount of its new 2030 Senior Secured Notes with certain of the holders of the Company's 2028 Convertible Notes and/or the Company's 2030 Convertible Notes in a privately negotiated exchange (the "Exchange") pursuant to Rule 144A under the Securities Act of 1933, as amended.

The transaction included an exchange of approximately (i) $228.8 million principal amount of the 2028 Convertible Notes and (ii) $121.3 million principal amount of the 2030 Convertible Notes, less amounts in lieu of fractional notes, for the 2030 Senior Secured Notes, warrants to purchase 439,919 shares of common stock (the "2030 Private Placement Warrants"), (iii) $10.0 million of cash proceeds, and accrued and unpaid interest on the exchanged 2028 Convertible Notes and 2030 Convertible Notes. The exchange resulted in a $220.0 million gain on debt extinguishment recorded within other income (expenses), net in the unaudited condensed consolidated statements of operations. The gain on debt extinguishment represented the proportional carrying value of the exchanged 2028 Convertible Notes and 2030 Convertible Notes, which in aggregate was

------

$343.9 million, reduced by the collective fair value of the 2030 Senior Secured Notes of $132.0 million and the fair value of the 2030 Private Placement Warrants of $2.7 million, offset by cash received. The fair value of the 2030 Senior Secured Notes was estimated using a Black Derman-Toy lattice model with a yield of approximately 14.6%, synthetic credit rating for the Company, volatility of 32%, and the risk free rate of 3.79% for the expected term associated with the 2030 secured notes. The fair value of the 2030 Private Placement Warrants was estimated using the Black-Scholes-Merton model based on the Company's closing strike price on the date of extinguishment of $6.23, volatility of 121.60%, and the risk free rate of 3.79% for the expected term associated with the 2030 secured notes. The Company accrued $5.2 million in debt issuance costs primarily consisting of financial advisory, legal, and accounting fees. See *2028 Convertible Notes and 2030 Convertible Notes* above for further details on the impacts of the debt extinguishment.

At the Company's election for any interest period, the 2030 Senior Secured Notes bear interest at a rate of (i) 12.00% per year, if interest is paid in kind, subject to a maximum amount of interest able to be paid in kind, and (ii) 11.00% per year if interest is paid in cash. In each case, interest is payable semi-annually in arrears in January and July of each year, beginning on January 1, 2026. The 2030 Senior Secured Notes will mature on December 30, 2030 unless redeemed in accordance with their terms prior to such date.

The 2030 Senior Secured Notes will be redeemable, in whole or in part, for cash at the Company's option at any time, and from time to time, at the following redemption prices: on or after the date of issuance to December 31, 2027, at 105.00% of the principal amount of the notes being redeemed, including interest paid in kind, if any, plus accrued and unpaid interest; from January 1, 2028 to December 31, 2028, at 102.50% of the principal amount of the notes being redeemed, including interest paid in kind, if any, plus accrued and unpaid interest; and on or after January 1, 2029, at 100.00% of the principal amount of the notes being redeemed, including interest paid in kind, if any, plus accrued and unpaid interest.

***At-the Market Program***

On March 6, 2026, the Company entered into an open market sales agreement with Jeffries LLC (the "Agent"), as sales agent and/or principal, providing for an "at-the-market" equity offering program (the "ATM Program") pursuant to which the Company may issue and sell from time to time shares of its common stock, par value $0.0001 per share, having an aggregate offering price of up to $30.0 million (the "Shares") to or through the Agent in ordinary brokers' transactions on the NYSE or otherwise, at market prices prevailing at the time of sale, in block transactions, in negotiated transactions, in any matter permitted by applicable law or as otherwise agreed with the Agent. We intend to use any net proceeds received from the sale of the shares for general corporate purposes, including working capital. As of March 31, 2026, no shares have been issued under the ATM Program.

**Off-Balance Sheet Arrangements**

We are not a party to any off-balance sheet arrangements, including guarantee contracts, retained or contingent interests, or unconsolidated VIEs that either have, or would reasonably be expected to have, a current or future material adverse effect on our unaudited condensed consolidated financial statements.

**Critical Accounting Policies and Estimates**

A summary of our critical accounting policies and estimates is presented in our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, and there have been no material changes to our critical accounting estimates during the three months ended March 31, 2026.

**ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

We are a smaller reporting company, as defined by Rule 12b-2 under the Securities and Exchange Act of 1934, as amended, and in Item 10(f)(1) of Regulation S-K, and are not required to provide the information under this item.

------

**ITEM 4. CONTROLS AND PROCEDURES**

**Evaluation of Disclosure Controls and Procedures**

We maintain disclosure controls and procedures ("Disclosure Controls") within the meaning of Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended ("Exchange Act"). Our Disclosure Controls are designed to provide reasonable assurance that information required to be disclosed by us in the reports we file or submit under the Exchange Act, such as this Quarterly Report on Form 10-Q, is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission's rules and forms. Our Disclosure Controls are also designed to provide reasonable assurance that such information is accumulated and communicated to our management, including our Chief Executive Officer ("CEO") and Chief Financial Officer ("CFO"), as appropriate, to allow timely decisions regarding required disclosure.

Based on management's evaluation (under the supervision and with the participation of our CEO and our CFO) of the effectiveness of the design and operation of our Disclosure Controls as of March 31, 2026, our CEO and CFO have concluded that our Disclosure Controls were effective at a reasonable assurance level.

**Changes in Internal Control over Financial Reporting**

There were no changes in our internal controls over financial reporting during the first quarter of 2026, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

**Inherent Limitations on Effectiveness of Internal Controls**

Our management, including our CEO and CFO, does not expect that our disclosure controls or our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system's objectives will be met. The design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Furthermore, because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Projections of any evaluation of the effectiveness of controls to future periods are subject to risks. Over time, controls may become inadequate because of changes in business conditions or deterioration in the degree of compliance with policies or procedures.
