1. BUSINESS ORGANIZATION, NATURE OF OPERATIONS, RISKS AND UNCERTAINTIES

Pioneer Power Solutions, Inc. and its wholly owned subsidiaries (referred to herein as the “Company,” “Pioneer,” “we,” “our” and “us”) design, manufacture, integrate, refurbish, service, distribute and sell electric power systems, distributed energy resources, power generation equipment and mobile electric vehicle (“EV”) charging solutions. Our products and services are sold to a broad range of customers in the utility, industrial and commercial markets. Our customers include, but are not limited to, electric, gas and water utilities, data center developers and owners, EV charging infrastructure developers and owners, and distributed energy developers. The Company is headquartered in Fort Lee, New Jersey and operates from three (3) additional locations in the U.S. for manufacturing, service and maintenance, engineering, sales and administration.

We have two reportable segments as defined in our Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the Securities and Exchange Commission (the “SEC”) on April 11, 2023: Transmission and Distribution Solutions (“T&D Solutions”) and Critical Power Solutions (“Critical Power”).

Presentation

The accompanying unaudited interim consolidated financial statements of the Company have been prepared pursuant to the rules of the SEC and reflect the accounts of the Company as of June 30, 2023. Certain information and footnote disclosures, normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”), have been condensed or omitted pursuant to those rules and regulations. We believe 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 financial statements but does not include all disclosures required by U.S. GAAP for a year-end balance sheet.

All dollar amounts (except share and per share data) presented in the notes to our unaudited interim consolidated financial statements are stated in thousands of dollars, unless otherwise noted. Amounts may not foot due to rounding. 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. We have used a discrete-period computation method to calculate taxes for the fiscal three and six-month period ended June 30, 2023. The Company anticipates that its annual effective tax rate will be 0% for the year ending December 31, 2023. As of June 30, 2023, the Company continues to provide a 100% valuation allowance against its net deferred tax assets since the Company believes it is more likely than not that its deferred tax assets will not be realized.

These unaudited interim consolidated financial statements include the accounts of Pioneer and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.

These unaudited interim consolidated financial statements should be read in conjunction with the risk factors under the heading “Part II - Item 1A. Risk Factors” and the risk factors and the audited consolidated financial statements and notes thereto of the Company and its subsidiaries included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.

Liquidity

The accompanying financial statements have been prepared on a basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. As shown in the accompanying financial statements, as of June 30, 2023, the Company had $9,624 of cash on hand and working capital of $14,363. The cash on hand was generated primarily from the sale of common stock under the ATM Program (as defined below) during the year ended December 31, 2021 and payment of all unpaid principal and interest from the two subordinated promissory notes we received in connection with the sale of the transformer business units in August 2019 for an aggregate principal amount of $7,500 (the “Seller Notes”) during the year ended December 31, 2022.

We have met our cash needs through a combination of cash flows from operating activities and bank borrowings, the completion of the Equity Transaction, proceeds from the sale of the CleanSpark common stock and warrants to purchase CleanSpark common stock, sale of common stock under the ATM Program, funding from the Payroll Protection Program and collecting all unpaid principal and interest from the Seller Notes. Our cash requirements historically were generally for operating activities, debt repayment, capital improvements and acquisitions. We expect to meet our cash needs with our working capital and cash flows from our operating activities. We expect our 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.

On December 13, 2021, we filed a prospectus supplement, which forms a part of our registration statement on Form S-3 (File No. 333-249569), that was declared effective by the SEC on October 27, 2020, in connection with the offer and sale of up to an aggregate offering amount of $8,600 of common stock that may be issued and sold under the ATM Program. We did not sell any shares of common stock under the ATM Program during the six months ended June 30, 2023. As of June 30, 2023, $8,600 of common stock remained available for issuance under the ATM Program.

Risks and Uncertainties

The World Health Organization determined that COVID-19 no longer fit the definition of a public health emergency and the U.S. government announced that the declaration of a public health emergency associated with COVID-19 expired on May 11, 2023. However, COVID-19 has remained and is expected to continue to remain as a serious endemic threat for an indefinite future period and may continue to adversely affect the global economy. The continuing impacts of the COVID-19 endemic, as well as rising interest rates, inflation, changes in foreign currency exchange rates and geopolitical developments (including the war in Ukraine) 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. 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 continuing impacts of the COVID-19 endemic and the extent of geopolitical disruption and their respective impacts 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. During the six months ended June 30, 2023, the Company was able to operate substantially at capacity.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The Company’s significant accounting policies are described in Note 2 to the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. There have been no significant changes in the Company’s accounting policies during the second quarter of 2023.

Recent Accounting Pronouncements

There have been no recent accounting pronouncements not yet adopted by the Company which would have a material impact on the Company’s financial statements.

Accounting Standards Update (“ASU”) 2023-03, “Presentation of Financial Statements (Topic 205), Income Statement - Reporting Comprehensive Income (Topic 220), Distinguishing Liabilities from Equity (Topic 480), Equity (Topic 505), and Compensation - Stock Compensation (Topic 718): Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 120, SEC Staff Announcement at the March 24, 2022 Emerging Issues Task Force (“EITF”) Meeting, and Staff Accounting Bulletin Topic 6.B, Accounting Series Release 280 - General Revision of Regulation S-X: Income or Loss Applicable to Common Stock.” ASU 2023-03 amends the ASC for SEC updates pursuant to SEC Staff Accounting Bulletin No. 120; SEC Staff Announcement at the March 24, 2022 EITF Meeting; and Staff Accounting Bulletin Topic 6.B, Accounting Series Release 280 - General Revision of Regulation S-X: Income or Loss Applicable to Common Stock. These updates were immediately effective and did not have a significant impact on our financial statements.

Accounts Receivable

On January 1, 2023, the Company adopted ASU 2016-13, “Financial Instruments - Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments,” using a modified retrospective approach. The standard amends several aspects of the measurement of credit losses related to certain financial instruments, including the replacement of the existing incurred credit loss model and other models with the current expected credit losses model. The cumulative effect of adoption did not result in an adjustment to the allowance for credit loss, and accordingly, the Company’s accumulated deficit as of January 1, 2023.

The Company accounts for trade receivables at original invoice amount less an estimate made for expected credit losses. The Company’s allowance for expected credit losses on accounts receivable reflects management’s estimate of credit losses over the remaining expected life of such assets, measured primarily using historical experience, as well as current conditions and forecasts that affect the collectability of the reported amount. There were no allowances for expected credit losses as of June 30, 2023 and December 31, 2022.

3. REVENUES

Nature of our products and services

Our principal products and services include electric power systems, distributed energy resources, power generation equipment and mobile EV charging solutions.

Products

Our T&D Solutions business provides electric power systems and distributed energy resources that help customers effectively and efficiently protect, control, transfer, monitor and manage their electric energy requirements.

Our Critical Power business provides customers with our suite of mobile e-Boost electric vehicle charging solutions and power generation equipment.

Services

Power generation systems represent considerable investments that require proper maintenance and service in order to operate reliably during a time of emergency. Our power maintenance programs provide preventative maintenance, repair and support service for our customers’ power generation systems.

Our principal source of revenue is derived from sales of products and fees for services. We measure revenue based upon the consideration specified in the customer arrangement, and revenue is recognized when the performance obligations in the customer arrangement are satisfied. A performance obligation is a promise in a contract to transfer a distinct product or service to the customer. The transaction price of a contract is allocated to each distinct performance obligation and recognized as revenue when or as, the customer receives the benefit of the performance obligation. Customers typically receive the benefit of our products when the risk of loss or control for the product transfers to the customer and for services as they are performed. Under ASC 606, revenue is recognized when a customer obtains control of promised products or services in an amount that reflects the consideration we expect to receive in exchange for those products or services.

During the three months ended June 30, 2023, the Company recognized $2,467 of revenue over time and incurred costs of $2,103. During the three months ended June 30, 2022, the Company recognized $574 of revenue over time and incurred costs of $592. Additionally, the Company recognized $7,773 and $2,432 of revenue at a point in time from the sale of our products during the three months ended June 30, 2023 and 2022, respectively.

Service revenues include maintenance contracts that are recognized over time based on the contract term and repair services which are recognized as services are delivered. The Company recognized $1,890 and $1,857 of service revenue during the three months ended June 30, 2023 and 2022, respectively.

During the six months ended June 30, 2023, the Company recognized $3,128 of revenue over time and incurred costs of $2,652. During the six months ended June 30, 2022, the Company recognized $900 of revenue over time and incurred costs of $870. Additionally, the Company recognized $13,558 and $6,934 of revenue at a point in time from the sale of our products during the six months ended June 30, 2023 and 2022, respectively.

Service revenues include maintenance contracts that are recognized over time based on the contract term and repair services which are recognized as services are delivered. The Company recognized $3,952 and $3,391 of service revenue during the six months ended June 30, 2023 and 2022, respectively.

During the three months ended June 30, 2023, the Company recognized approximately $3,285 of revenue that was recognized as deferred revenue at December 31, 2022, as compared to $214 of revenue during the three months ended June 30, 2022 that was recognized as deferred revenue at December 31, 2021.

During the six months ended June 30, 2023, the Company recognized approximately $7,794 of revenue that was recognized as deferred revenue at December 31, 2022, as compared to $2,056 of revenue during the six months ended June 30, 2022 that was recognized as deferred revenue at December 31, 2021.

The Company manages its accounts receivable credit risk by performing credit evaluations and monitoring amounts due from the Company’s customers. The Company had certain customers whose revenue individually represented 10% or more of the Company’s total revenue, or whose accounts receivable balances individually represented 10% or more of the Company’s total accounts receivable.

As of June 30, 2023, two customers represented approximately 60% and 16% of the Company’s accounts receivable. At December 31, 2022, three customers represented approximately 57%, 13% and 11% of the Company’s accounts receivable.

For the three months ended June 30, 2023, one customer represented approximately 63% of the Company’s revenue. For the three months ended June 30, 2022, two customers represented approximately 35% and 11% of the Company’s revenue.

For the six months ended June 30, 2023, two customers represented approximately 57% and 10% of the Company’s revenue. For the six months ended June 30, 2022, three customers represented approximately 18%, 16% and 13% of the Company’s revenue.

Return of a product requires that the buyer obtain permission in writing from the Company. When the buyer requests authorization to return material for reasons of their own, the buyer will be charged for placing the returned goods in saleable condition, restocking charges and for any outgoing and incoming transportation paid by the Company. The Company warrants title to the products, and also warrants the products on date of shipment to the buyer, to be of the kind and quality described in the contract, merchantable, and free of defects in workmanship and material. Returns and warranties during the three and six months ended June 30, 2023 and 2022 were insignificant.

The following table presents our revenues disaggregated by revenue discipline:

See “Note 10 - Business Segment and Geographic Information”.

4. REVISION OF PRIOR PERIOD FINANCIAL STATEMENTS

In connection with the preparation of our consolidated interim financial statements for the quarter ended September 30, 2022, we completed an analysis of one of our customer contracts under ASC 606 and, as a result, we determined that the performance obligations are satisfied over time. See “Note 3 – Revenues in Notes to Consolidated Financial Statements” in Part I of this Quarterly Report on Form 10-Q. As a result of the analysis, we identified additional revenues to be recognized of $574 and $900 related to the three and six months ended June 30, 2022, respectively, along with the additional related cost of revenues of $592 and $870, respectively.

The following tables reconcile the balances as previously reported in the Quarterly Reports on Form 10-Q as of and for the three and six months ended June 30, 2022 to the as revised balances:

 SCHEDULE OF PRIOR PERIOD FINANCIAL STATEMENTS 

In accordance with SEC Staff Accounting Bulletin No. 108, we evaluated this revision based on an analysis of quantitative and qualitative factors as to whether it was material to the consolidated statements of operations for the three and six months ended June 30, 2022 and if amendments of previously filed financial statements with the SEC are required. We determined that the adjustment is neither quantitatively nor qualitatively material and, therefore, the revision does not have a material impact to the consolidated statements of operations for the three and six months ended June 30, 2022 or other prior periods.

9. BASIC AND DILUTED LOSS PER COMMON SHARE

Basic and diluted loss per common share is calculated based on the weighted average number of vested shares outstanding during the period. The Company’s employee and director equity awards, as well as incremental shares issuable upon exercise of warrants, are not considered in the calculations if the effect would be anti-dilutive.

As of June 30, 2023 and 2022, diluted loss per share excludes potentially dilutive common shares related to 713,167 and 670,667 shares underlying stock options, respectively, and 125,000 and 250,000 shares underlying nonvested RSUs, respectively, as their effect was anti-dilutive.

10. BUSINESS SEGMENT AND GEOGRAPHIC INFORMATION

The Company follows ASC 280 - Segment Reporting in determining its reportable segments. The Company considered the way its management team, most notably its chief operating decision maker, makes operating decisions and assesses performance and considered which components of the Company’s enterprise have discrete financial information available. As the Company makes decisions using a manufactured products vs. distributed products and services group focus, its analysis resulted in two reportable segments: T&D Solutions and Critical Power. The Critical Power reportable segment is the Company’s Titan Energy Systems, Inc. business unit. The T&D Solutions reportable segment is the Company’s Pioneer Custom Electrical Products Corp. business unit.

The T&D Solutions segment is involved in the design, manufacture and sale of circuit protection and controls equipment used primarily by large industrial and commercial operations to manage their electrical power distribution needs. The Critical Power 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 following discussion and analysis of our financial condition and results of operations should be read in conjunction with the accompanying consolidated interim financial statements and related notes included elsewhere in this Quarterly Report on Form 10-Q and with our Annual Report on Form 10-K for the year ended December 31, 2022, which was filed with the Securities and Exchange Commission on April 11, 2023.

Unless the context requires otherwise, references in this Quarterly Report on Form 10-Q to the “Company,” “Pioneer,” “we,” “our” and “us” refer to Pioneer Power Solutions, Inc. and its subsidiaries.

U.S. dollars are reported in thousands except for share and per share amounts.

Special Note Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q contains “forward-looking statements,” which include information relating to future events, future financial performance, financial projections, strategies, expectations, competitive environment and regulation. Words such as “may,” “should,” “could,” “would,” “predicts,” “potential,” “continue,” “expects,” “anticipates,” “future,” “intends,” “plans,” “believes,” “estimates,” and similar expressions, as well as statements in future tense, identify forward-looking statements. Forward-looking statements should not be read as a guarantee of future performance or results and may not be accurate indications of when such performance or results will be achieved. Forward-looking statements are based on information we have when those statements are made or management’s good faith belief as of that time with respect to future events, and are subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in or suggested by the forward-looking statements. Important factors that could cause such differences include, but are not limited to:

The foregoing does not represent an exhaustive list of matters that may be covered by the forward-looking statements contained herein or risk factors that we are faced with that may cause our actual results to differ from those anticipated in our forward-looking statements. Moreover, new risks regularly emerge, and it is not possible for us to predict or articulate all risks we face, nor can we assess the impact of all risks on our business or the extent to which any risk, or combination of risks, may cause actual results to differ from those contained in any forward-looking statements. Except to the extent required by applicable laws or rules, we undertake no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise. You should review carefully the risks and uncertainties described under the heading “Part II - Item 1A. Risk Factors” in this Quarterly Report on Form 10-Q and “Part I - Item 1A. Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2022 for a discussion of the foregoing and other risks that relate to our business and investing in shares of our common stock.

Business Overview

We design, manufacture, integrate, refurbish, service, distribute and sell electric power systems, distributed energy resources, power generation equipment and mobile electric vehicle (“EV”) charging solutions. Our products and services are sold to a broad range of customers in the utility, industrial and commercial markets. Our customers include, but are not limited to, electric, gas and water utilities, data center developers and owners, EV charging infrastructure developers and owners, and distributed energy developers. We are headquartered in Fort Lee, New Jersey and operate from three (3) additional locations in the U.S. for manufacturing, service and maintenance, engineering, and sales and administration.

Description of Business Segments

We have two reportable segments: Transmission & Distribution Solutions (“T&D Solutions”) and Critical Power Solutions (“Critical Power”).

Critical Accounting Policies and Estimates

Our financial statements have been prepared in accordance with U.S. GAAP. The preparation of our financial statements requires us to make estimates and assumptions that affect the amounts and disclosures in the financial statements. Our estimates are based on our historical experience, knowledge of current events and actions we may undertake in the future, and on various other factors that we believe are reasonable under the circumstances. Our critical accounting policies and estimates are described in “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Policies” in our Annual Report on Form 10-K filed with the SEC on April 11, 2023. There were no material changes to our accounting policies during the six months ended June 30, 2023.

RESULTS OF OPERATIONS

Overview of the Three and Six Months Results

Selected financial and operating data for our reportable business segments for the most recent reporting period is summarized below. This information, as well as the selected financial data provided in “Note 10 - Business Segment and Geographic Information” and in our unaudited Consolidated Financial Statements and related notes included in this Quarterly Report on Form 10-Q, should be referred to when reading our discussion and analysis of results of operations below.

Our summary of operating results during the three and six months ended June 30, 2023 and 2022 are as follows:

Backlog

Our backlog is based on firm orders from our customers expected to be delivered in the future, most of which is expected to occur during the next twelve months. Backlog may vary significantly from reporting period to reporting period due to the timing of customer commitments. Backlog reflects the amount of revenue we expect to realize upon the shipment of customer orders for our products that are not yet complete or for which work has not yet begun. At June 30, 2023, backlog from our E-Bloc power systems solutions was approximately $15,300, or 46% of the total backlog.

The following table represents the progression of our backlog, by reporting segment, as of the end of the last five quarters:
