Pioneer Power Announces Financial Results for Second Quarter 2026 and Provides a Business Update

FORT LEE, N.J., Aug. 17, 2026 /BusinessWire/ — Pioneer Power Solutions, Inc. (Nasdaq: PPSI) (“Pioneer” or the “Company”), a leader in the design, manufacture, service and integration of distributed energy resources, power generation equipment and mobile electric vehicle (“EV”) charging solutions, today provided a business update and announced financial results for the second quarter ended June 30, 2026.

“Our PRYMUS on-site power system, introduced in December 2025, continues to gain traction as customers look for reliable, scalable power that can be deployed in months rather than years,” said Nathan Mazurek, CEO of Pioneer. “PRYMUS is designed to meet that demand, combining mobile prime power generation, battery energy storage and advanced controls in pre-engineered, modular blocks that can scale from 1 MW to 10 MW and be deployed where power is needed, when it is needed. The early response to the platform has been strong, highlighted by the up to $6 million award we announced in May from one of the nation’s largest package delivery companies for two PRYMUS systems to provide prime power at separate transit hubs.

“Although the initial systems are not expected to be delivered until the second half of 2026, this customer has indicated an interest in potentially ordering additional PRYMUS systems for delivery in the first half of 2027. At the same time, our pipeline continues to build, with active PRYMUS quotes totaling approximately $200 million in aggregate with roughly 80% related to data center projects. The level of engaged interest we are experiencing only months after launching PRYMUS is an indication of the platform’s strong potential and market reception. We fully expect to receive additional, significant PRYMUS orders in the second half of 2026.

“We believe what we are experiencing with PRYMUS reflects a broader shift taking place in the power market. Demand for power is growing exponentially, driven in large part by the expansion of data centers and other energy-intensive infrastructure, while the traditional grid faces increasing constraints on capacity and the speed of bringing new power online. Customers are increasingly looking for reliable power solutions that can be deployed where and when they are needed, and we believe that plays directly to the strengths of distributed generation and to our capabilities.

“Concurrently, our e-Boost mobile charging platform has achieved a solid baseline, with annual revenue of approximately $10 million and more consistent gross margin levels. Despite the broader challenges in the EV charging market, we believe this level of revenue and profitability provides a sustainable foundation for the current business. As the EV charging market in the United States and abroad continues to develop, we see opportunities to build on this baseline and improve both revenue and gross margins over time.

“Our PowerCore home product, which we also introduced in December 2025, establishes a new category in premium residential power, providing 24/7 whole-home energy resiliency and energy independence with integrated high-speed EV charging. We are continuing to advance the platform and remain on track to begin shipments in the second half of 2026, initially with our original 45 kW prime-rated system and subsequently with 150 kW and 250 kW versions designed for larger estate-level residences. This expanded product range gives Pioneer the opportunity to address a broader segment of the premium residential market and build a meaningful new growth opportunity over the next several years.”

Q2 2026 Financial Highlights

*A reconciliation between GAAP and non-GAAP measures is provided below. The non-GAAP measures should not be considered an alternative to GAAP measures as an indicator of the Company’s operating performance.

Second Quarter 2026 Financial Results

Revenue

Revenue for the three months ended June 30, 2026, was $5.0 million, a decrease of 40.0%, as compared to $8.4 million during the second quarter of last year, primarily due to a decrease in sales and rentals in the Company’s suite of mobile EV charging solutions, e-Boost.

Gross Profit/Margin

Gross profit for the second quarter of 2026 was $984,000, or a 19.6% gross margin, compared to gross profit of $1.3 million, or a 15.7% gross margin, for the same period in 2025. The increase in gross margin was primarily attributable to improved operating efficiencies associated with the sale of the Company’s mobile EV charging solutions, e-Boost.

Operating Loss from Continuing Operations

For the three months ended June 30, 2026, operating loss from continuing operations was $2.0 million, as compared to $1.7 million for the same period in 2025, primarily due to the decrease in sales and rentals of our equipment and services.

Net Loss

Net loss was $2.1 million, as compared to $1.3 million, inclusive of a loss from discontinued operations of $100,000, for the same period last year.

Balance Sheet

As of June 30, 2026, the Company had $10.7 million of cash on hand and working capital of $17.1 million, compared to $15.0 million of cash on hand and working capital of $20.7 million as of December 31, 2025. The Company had no bank debt as of June 30, 2026.

Second Half 2026 Outlook

Management expects revenue of approximately $15.0 million for the second half of 2026, representing growth of more than 60% as compared to the first half of 2026.

At the end of April, the Company took steps to streamline its organization and better align its cost structure with the scale of the business. Management expects the benefits of these actions to become increasingly evident in the second half of the year.

The foregoing projected outlook constitutes forward-looking information and is intended to provide information about management’s current expectations for the Company’s 2026 fiscal year. Although considered reasonable as of the date hereof, this outlook, and the underlying assumptions may prove to be inaccurate. Accordingly, actual results could differ materially from the Company’s expectations as set forth herein. See “Forward-Looking Statements.”

In preparing the above outlook, the Company assumed, among other things, (i) that the Company’s backlog orders will translate into revenue, (ii) that the Company will be able to satisfactorily complete and deliver all orders and (iii) the timely payment by customers for all billings. This section includes forward-looking statements. See “Forward-Looking Statements.”

Non-GAAP Measures

In addition to disclosing financial results in accordance with accounting principles generally accepted in the United States of America (“GAAP”), this document references certain non-GAAP financial measures. The Company defines non-GAAP operating income (loss) from continuing operations as GAAP operating income (loss) from continuing operations excluding corporate overhead expenses, research and development expenses, depreciation and amortization expenses, and non-recurring professional fees. We believe these non-GAAP financial measures provide investors with useful supplemental information about our operating performance and enable comparison of financial trends and results between periods where certain items may vary, independent of business performance.

The Company’s management uses non-GAAP operating income (loss) from continuing operations (a) as a measure of operating performance, (b) for planning and forecasting in future periods, and (c) in communications with the Company’s board of directors concerning the Company’s financial performance. The Company’s presentation of this non-GAAP measure is not necessarily comparable to other similarly titled captions of other companies due to different methods of calculation and should not be used by investors as a substitute for or alternative to any measure of financial performance calculated and presented in accordance with GAAP. Instead, management believes this non-GAAP measure should be used to supplement the Company’s financial measures derived in accordance with U.S. GAAP in order to provide a more complete understanding of the trends affecting the business.

Please refer to “Reconciliation of Non-GAAP Measures” in this document for a detailed explanation of the adjustments made to the comparable GAAP measures.
