Pioneer’s products and services are sold to a broad range of customers in the utility, industrial and commercial markets. Pioneer’s customers include, but are not limited to, federal and state government entities, package delivery business’, school bus fleet operations, EV charging infrastructure developers and owners, and distributed energy developers. Pioneer is headquartered in Fort Lee, New Jersey and operates from two (2) additional locations in the United States for manufacturing, service and maintenance, engineering, sales and administration.

Segments

In determining operating and reportable segments in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 280, Segment Reporting (“ASC 280”), the Company concluded that it hasone reportable segment: Critical Power Solutions (“Critical Power”), as defined in its Annual Report on Form 10-K for the year ended December 31, 2024, as filed with the Securities and Exchange Commission (the “SEC”) on April 14, 2025.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X. Accordingly, they do not include all of the information and disclosures required by U.S. GAAP for complete financial statements. The Company believes that the disclosures made are adequate to make the information presented not misleading to the reader. In the opinion of management, all adjustments, consisting only of normal recurring adjustments, necessary to fairly state the financial position, results of operations and cash flows with respect to the interim consolidated financial statements have been included. The results of operations for the interim period are not necessarily indicative of the results for the entire fiscal year. The year-end balance sheet data was derived from audited consolidated financial statements but this filing does not include all disclosures required by U.S. GAAP for a year-end balance sheet.

ASC 740-270 requires the use of an estimated annual effective tax rate to compute the tax provision during an interim period unless certain exceptions are met. The Company is currently in the process of estimating its annual effective tax rate for the year ending December 31, 2025, and, as such, the annual effective tax rate is unknown.

These unaudited condensed interim consolidated financial statements include the accounts of Pioneer and Titan Energy Systems, Inc. (“Titan”), its wholly owned subsidiary. All significant intercompany accounts and transactions have been eliminated in consolidation.

These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto of the Company and its subsidiary included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

Liquidity

The accompanying unaudited condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. As shown in the accompanying unaudited condensed consolidated financial statements, as of June 30, 2025, the Company had $17,999 of cash on hand and working capital of $23,916. The cash on hand was generated primarily from the sale (the “PCEP Sale”) of the Company’s former wholly owned subsidiary, Pioneer Custom Electrical Products Corp. (“PCEP”). On October 29, 2024, the Company closed on the PCEP sale for gross cash proceeds of $48,000 and $2,000 in equity. As of December 31, 2024, the Company recorded a consideration due to the buyer of the PCEP Sale of $3,347 related to a net working capital adjustment. On April 16, 2025, the Company and the buyer of the PCEP Sale finalized the net working capital adjustment and as a result, the Company recorded a $1,147 adjustment to the consideration due to the buyer of the PCEP Sale during the three months ended March 31, 2025. On April 16, 2025, the Company paid the $2,200 consideration payable due to the buyer of the PCEP Sale. See Note 8 – Discontinued Operations for details.

The Company has historically met its cash needs through a combination of cash flows from operating activities and bank borrowings, the completion of the sale of the transformer business units in August 2019, the completion of the sale of the PCEP business unit in October 2024, and the sale of common stock. Historically, the Company’s cash requirements were generally for operating activities, debt repayment, capital improvements and acquisitions. The Company expects to meet its cash needs with the working capital and cash flows from the Company’s operating activities. The Company expects its cash requirements to be generally for operating activities, product development and capital improvements. The Company expects that its current cash balance is sufficient to fund operations for the next twelve months from the date our unaudited condensed consolidated financial statements are issued.

Risks and Uncertainties

The continuing impacts of the rising interest rates, inflation, changes in foreign currency exchange rates and geopolitical developments, such as the ongoing conflict between Russia and Ukraine, and the ongoing conflict between Israel and Hamas, have resulted, and may continue to result, in a global slowdown of economic activity, which may decrease demand for a broad variety of goods and services, including those provided by the Company’s clients, while also disrupting supply channels, sales channels and advertising and marketing activities for an unknown period of time. Additionally, recent changes to U.S. policy implemented by the U.S. Congress, the Trump administration or any new administration have impacted and may in the future impact, among other things, the U.S. and global economy, tariff policies and regulations, international trade relations, unemployment, immigration, healthcare, taxation, the U.S. regulatory environment, inflation and other areas. As a result of the current uncertainty in economic activity, the Company is unable to predict the potential size and duration of the impact on its revenue and its results of operations, if any. The extent of the potential impact of these macroeconomic factors on the Company’s operational and financial performance will depend on a variety of factors, including the extent of geopolitical disruption and its impact on the Company’s clients, partners, industry, and employees, all of which are uncertain at this time and cannot be accurately predicted. The Company continues to monitor the effects of these macroeconomic factors and intends to take steps deemed appropriate to limit the impact on its business.

There can be no assurance that precautionary measures, whether adopted by the Company or imposed by others, will be effective, and such measures could negatively affect its sales, marketing, and client service efforts, delay and lengthen its sales cycles, decrease its employees’, clients’, or partners’ productivity, or create operational or other challenges, any of which could harm its business and results of operations.

All dollar amounts (except share and per share data) presented are stated in thousands of dollars, unless otherwise noted. Amounts may not foot due to rounding.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Since the Annual Report for the year ended December 31, 2024, there have been no material changes to the Company’s significant accounting policies, except as disclosed in this note.

Recent Accounting Pronouncements

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures, which requires enhanced income tax disclosures that reflect how operations and related tax risks, as well as how tax planning and operational opportunities, affect the tax rate and prospects for future cash flows. This standard is effective for the Company’s annual reporting beginning January 1, 2025 with early adoption permitted. The Company is currently assessing the impact that adoption of this new accounting guidance will have on its consolidated financial statements and footnote disclosures.

In November 2024, the FASB issued ASU 2024-03, “Income Statement - Reporting Comprehensive Income Expense Disaggregation Disclosures (Subtopic 220- 40)”, and in January 2025, the FASB issued ASU 2025-01, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date”. This standard requires public companies to disclose additional information about specific expense categories in the notes to financial statements at interim and annual reporting periods. The new standard, as clarified by ASU 2025-01, is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently assessing the impact that adoption of this new accounting guidance will have on its consolidated financial statements and footnote disclosures.

In May 2025, the FASB issued ASU 2025-04, “Compensation—Stock Compensation (Topic 718) and Revenue from Contracts with Customers (Topic 606): Scope Application of Profits Interest and Share-Based Customer Payments”. This ASU provides clarification on how to account for share-based payments made to customers, including updated guidance on performance conditions and forfeiture estimation. It also removes the reference to the ASC 606 constraint guidance for recognizing such awards. The amendments are effective for fiscal years beginning after December 15, 2026, including interim periods within those fiscal years, with early adoption permitted. The Company is currently assessing the impact that adoption of this new accounting guidance will have on its consolidated financial statements and footnote disclosures.

Revenue Recognition

Bill and Hold Arrangements

From time to time, the Company enters into bill and hold arrangements, whereby the Company sells mobile EV charging equipment and the equipment is warehoused at a Company or third party location pursuant to directions received from the Company’s customer. Even though the equipment is not physically in the customer’s possession, a sale is recognized at the point in time when the customer obtains control of the product. Control is transferred to the customer in a bill and hold arrangement when: customer acceptance specifications have been met, legal title has transferred, the customer has a present obligation to pay for the product and the risk and rewards of ownership have transferred to the customer.

Additionally, all the following bill and hold criteria must be met in order for control to be transferred to the customer: the reason for the bill and hold arrangement is substantive, the customer has requested the product be warehoused, the product has been identified as separately belonging to the customer, the product is currently ready for physical transfer to the customer, and the Company does not have the ability to use the product or direct it to another customer.

Lessor Arrangements

The Company determines whether an arrangement is or contains a lease at inception. The Company leases generators and mobile electric vehicle charging equipment to certain of its customers. As a lessor, when a lease meets certain criteria indicating that the Company has effectively transferred control of the underlying asset to the customer, the lease is classified as a sales-type lease. When a lease does not meet the criteria for a sales-type lease but meets the criteria of a direct financing lease, the lease is classified as a direct financing lease. When none of the required criteria for sales-type lease or direct-financing lease are met, the lease is classified as an operating lease. Sales-type leases are recognized as a net investment in the lease on the unaudited consolidated balance sheets. The net investment comprises the lease receivable including any unguaranteed residual value of the underlying asset. For sales-type leases, product revenue is generally recognized upon lease commencement. The discounted unguaranteed residual value of the underlying leased assets is not material to the net investment in the lease balance. The Company monitors the performance of customers who leased equipment and are subject to ongoing payments. No allowance has been recorded for the receivables under the leasing arrangements.

The lease terms are included in the Company’s contracts and the determination of whether the Company’s contracts contain leases generally does not require significant assumptions or judgments. Leasing revenues do not include material amounts of variable payments. Lessees do not provide residual value guarantees on rented equipment.

3. REVENUES

4. INVENTORIES

The components of inventories are summarized below:

5. ACCOUNTS PAYABLE AND ACCRUED LIABILITIES

The components of accounts payable and accrued liabilities are summarized below:

Accrued liabilities primarily consist of accrued insurance, accrued compensation and benefits and accrued warranty costs. As of June 30, 2025, and December 31, 2024, accrued insurance was $106 and $462, respectively.

The remainder of accrued liabilities are comprised of several insignificant accruals in connection with normal business operations.

6. STOCK-BASED COMPENSATION

Stock-Based Compensation

A summary of stock option activity during the six months ended June 30, 2025, is as follows:

Stock-based compensation expense recorded for the three and six months ended June 30, 2025, was approximately $2 and $15, respectively.

As of June 30, 2025, there was $43 of stock-based compensation expense remaining to be recognized in the consolidated statements of operations over a weighted average remaining period of 1.1 years.

7. INCOME TAXES

For the three and six months ended June 30, 2025, the Company recorded no provision for income taxes, resulting in an effective tax rate (ETR) of 0%, compared to the U.S. federal statutory rate of 21%. The difference between the Company’s ETR and the statutory rate was primarily driven by the following significant reconciling items:

As a result, despite incurring a pre-tax loss in the quarter, the Company recorded no tax benefit.

The Company also notes that the prior year December 31, 2024 effective tax rate was 29.75%, primarily due to a discrete gain on the sale of a subsidiary that generated taxable income and allowed the Company to utilize previously reserved capital loss and net operating loss carryforwards, resulting in a partial release of the valuation allowance. No such income or attribute utilization occurred in the current period.

Additionally, due to earnings volatility and the non-reliability of full-year forecasted income, management concluded it was not practicable to estimate a reliable annual effective tax rate. As such, the Company applied the discrete method under ASC 740-270-30-18 to calculate the interim income tax provision.

The Company will continue to apply the discrete method until reliable forecast data becomes available to support a forecast-based ETR.

On July 4, 2025, the President signed into law the “Make Rural America and Main Street Grow Again Act” (commonly referred to as the One Big Beautiful Bill Act), which makes several significant changes to U.S. federal income tax law. Key provisions include:

Because the law was enacted after the end of the second quarter, its effects are considered a nonrecognized subsequent event and do not reflect any adjustments related to the enacted provisions.

Certain provisions of the legislation are effective retroactively to earlier periods in 2025. These may result in catch up adjustments in the third quarter to the income tax accounts. The Company is currently assessing the impact of these retroactive provisions, including any related remeasurement of deferred tax assets, liabilities, and valuation allowance considerations. The Company maintains a valuation allowance on its deferred tax assets and does not expect a material near-term tax benefit from legislation due to its current net operating loss position.

8. DISCONTINUED OPERATIONS

Sale of Electrical Infrastructure Segment

On October 29, 2024, the Company entered into an Equity Contribution and Purchase Agreement (the “Equity Purchase Agreement”), by and among the Company, PCEP, Voltaris Power LLC (the “Buyer”) and Pioneer Investment LLC (“Investment”).

11. BUSINESS SEGMENT AND GEOGRAPHIC INFORMATION

The Chief Executive Officer of the company (the “CEO”), as the Chief Operating Decision Maker (“CODM”), organizes the Company, manages resource allocations, and measures performance of the Company’s single operating segment, Critical Power Solutions. The Critical Power Solutions reportable segment is the Company’s Titan business unit. The Critical Power Solutions segment provides mobile high-capacity charging equipment, power generation equipment and aftermarket field-services in order to help customers secure fast vehicle charging where fixed charging infrastructure does not exist, and additionally to ensure smooth, uninterrupted power to operations during times of emergency.

The CODM assesses the Company’s performance and decides how to allocate resources based on consolidated net income (loss) in the unaudited condensed consolidated statements of operations, which is assessed to be the segment measure of profit or loss. This measure is used to monitor actual results to evaluate the performance of the segment versus the forecasted targets. The segment assets are equal to the assets presented in the unaudited condensed consolidated balance sheets.

The significant expenses that are regularly provided to the CODM, which include costs of goods sold, selling, general and administrative expenses and research and development expenses, are disclosed in the unaudited condensed consolidated statements of operations as a part of the consolidated net income (loss). The other segment item that is regularly provided to the CODM includes other income (expense) which is disclosed as a separate line item in the unaudited condensed consolidated statements of operations. Other income and (expenses) consist of interest income and interest (expense), which are disclosed as separate line items in the unaudited condensed consolidated statements of operations.

On October 29, 2024, the Company sold its Electrical Infrastructure segment to Mill Point Capital. Prior to the sale of the Electrical Infrastructure segment, the Company’s CODM assessed performance and allocated resources amongst itstwo reportable segments. See Note 8 - Discontinued Operations for additional information.
