Management Commentary

"The second quarter of 2025 was highlighted by two of the most successful sales months in our history, providing exceptional sales growth and momentum,” said Brian Schaffner, Chief Executive Officer and Interim Chief Financial Officer. “Net sales grew 134% year over year to $3.0 million, and sequentially for a sixth consecutive quarter on strong organic sales within our large customer base of dealers, distributors, OEMs and private label clients.

“Gross margin was adversely affected by ongoing tariff uncertainty during the quarter and increased volume of lower margin pass-through product sales, decreasing from 24% in Q1 2025 to 21% in Q2 2025. Gross margin impact was partially offset by our previous tariff mitigation efforts of adding 6-12 months of inventory before new tariffs were introduced, which reduced costs within our current line of batteries. We are also seeking to improve margins by diversifying our supply chain and have already transitioned certain products to U.S.-based manufacturers. This shift has resulted in lower costs for these products given the current tariff environment—particularly for steel and aluminum accessories—and we continue to explore additional sourcing opportunities from other countries. Our long-term goal is to onshore manufacturing of most of our components and assemblies. We are also actively engaged with resources in Washington, D.C. to advocate for reduced tariff impacts on our business and operations.”

“Our Home Energy Storage Solutions (HESS), which began production earlier this year, enable residential and small business customers to create their own stable micro-energy grid and lessen the impact of increasing power fluctuations and outages. Of our two home energy product options, one has achieved UL9540 certification, and the second is in the final stages of UL approval. Proper UL certification is vital as states such as California require UL9540 certification of the battery and inverter system to qualify for tax credits.”

“Looking ahead, with our current balance sheet positioning, from a combination of cash, receivables, and strong inventory levels, we believe we are well positioned to execute on our key growth initiatives, including adding OEM partnerships and distributors, further developing HESS, and introducing new technologies and batteries. We remain focused on expanding distribution and advancing our lithium-ion battery technology,” concluded Mr. Schaffner.

Second Quarter 2025 Financial Summary

Net sales in the second quarter of 2025 totaled $3.0 million, an increase of 134% from $1.3 million in the prior year period. The increase in net sales was primarily attributable to sales growth in the RV market along with accessory sales growth through integrator partners.

Gross profit totaled $0.6 million, or 21% as a percentage of sales, as compared to $0.3 million, or 25% as a percentage of sales, in the prior year period. The decrease in gross margin percentage was primarily attributable to the product mix sold in different periods.

Selling, general and administrative expenses were $2.0 million, which was relatively flat compared to the prior year period, but reflecting a decrease of 91 percentage points as a percentage of sales, from 157% of sales in the second quarter of 2024 to 66% of sales in the second quarter of 2025. The nominal decrease was primarily due to reduced costs of rent and related expenses, partially offset by smaller increases in travel expense, research and development, and other expenses.

Net loss totaled $1.4 million, a 38% improvement from $2.2 million in the prior year period. The decrease in net loss was primarily the result of higher net sales combined with relatively flat selling, general, and administrative expenses.

First Half 2025 Financial Summary

For the six months ended June 30, 2025, net sales totaled $5.0 million, an increase of 124% from $2.2 million in the prior year period. The increase in net sales was primarily attributable to sales growth in the RV market along with accessory sales growth through integrator partners.

Gross profit totaled $1.1 million, or 22% as a percentage of sales, compared to $0.5 million, or 24% as a percentage of sales, in the prior year period. The decrease in gross margin percentage was primarily attributable to the product mix sold in different periods.

Selling, general and administrative expenses decreased 14% to $3.6 million compared to $4.2 million in the prior year period, and decreased as a percentage of sales by 114 percentage points, from 186% of sales in the first half of 2024 to 72% of sales in the first half of 2025. The decrease was primarily due to decreases in salaries and benefits, rent and related expenses, and legal and professional fees, slightly offset by an increase in research and development expenses.

Net loss totaled $2.5 million, a 43% improvement from $4.4 million in the prior year period. The decrease in net loss was primarily the result of higher net sales for the period combined with a decrease in selling, general, and administrative expenses.

Cash and cash equivalents totaled $0.7 million as of June 30, 2025, compared to $0.5 million as of December 31, 2024.

Net cash used in operating activities totaled $1.6 million, compared to $3.4 million in the prior year period. Receiving inventory that was prepaid during the prior period accounted for the majority of the change for the six months ended June 30, 2025.
