Management Commentary

"The third quarter of 2025 was underscored by continued revenue momentum on strong product sales growth, and the appointment of new leadership to steer the Company into its next phase of expansion,” said Joseph Hammer, Chief Executive Officer and Chairman of the Board of Directors of Expion360. “Net sales grew 72% year over year to $2.4 million, driven by strong organic sales of premium lithium iron phosphate (LiFePO4) batteries and accessories within our broad nationwide customer base of dealers, distributors, original equipment manufacturers, and private label clients. Our results demonstrate a meaningful recovery of demand in the RV market, combined with expanded outreach to OEMs and successful onboarding of new customers.

“Operationally, we recently made two leadership changes necessary to lead Expion360 to its next stage as an industry leader. Shawna Bowin, our former Controller, was appointed Chief Financial Officer. She is an accounting professional with over 20 years of progressive experience in accounting and a proven track record serving public and private companies. Her leadership as Controller, especially guiding us through the complexities of annual audits, quarterly reviews, and SEC reporting, makes her an ideal fit for the role. I was also privileged to be appointed as Chief Executive Officer and Chairman of the Board of Directors. I look forward to leveraging my over 20 years of experience as a veteran financial executive and Board member, along with my industry relationships, and working with our leadership team to lead the business into becoming a profitable industry leader in lithium-ion batteries solutions.

“Looking ahead, with a strong financial foundation built on cash, receivables, and healthy inventory levels, we believe we are well-equipped to drive our next phase of growth. Our near-term priorities include adding OEM market penetration with new major partners, further developing home energy storage solutions, and introducing new battery features, technologies, and unique OEM-centric form factors. I am excited to have joined Expion360 at such a pivotal moment in its growth and look forward to further announcements of our long-range plans for the business and other strategic initiatives in the months ahead, including a potential expansion into related energy storage areas or markets beyond energy,” concluded Mr. Hammer.

Third Quarter 2025 Financial Summary

Net sales in the third quarter of 2025 totaled $2.4 million, an increase of 72% from $1.4 million in the prior year period. The increase in net sales was primarily attributable to the RV market recovering from its previous slowdown, and enhanced sales efforts including expanded outreach to OEM partners, strategic marketing initiatives, and the successful onboarding of new customers during this period.

Gross profit totaled $0.5 million, or 23% as a percentage of net sales, as compared to $0.2 million, or 12% as a percentage of net sales, in the prior year period. The increase in gross margin percentage was primarily attributable to the product mix sold in different periods.

Selling, general, and administrative expenses in the third quarter of 2025 were $3.5 million, an increase of 69% from $2.1 million in the third quarter of 2024, but reflecting a decrease of three percentage points as a percent of net sales, from 151% in the third quarter of 2024 to 148% in the third quarter of 2025. The increase was primarily due to increases in salaries and benefits as well as legal and professional fees.

Net income in the third quarter of 2025 totaled $0.7 million, a $9.5 million improvement from a net loss of $8.8 million in the prior year period. The improvement was driven by increased sales and proportional decreases in cost of sales resulting in improved gross profit, as well as improvements in other income and expense.

Nine Months 2025 Financial Summary

For the nine months ended September 30, 2025, net sales totaled $7.4 million, an increase of 104% from $3.6 million in the prior year period. The increase in net sales was primarily attributable to the RV market recovering from its previous slowdown, and enhanced sales efforts including expanded outreach to OEM partners, strategic marketing initiatives, and the successful onboarding of new customers during this period.

Gross profit for the nine months ended September 30, 2025 increased 133% to $1.7 million, or 22% as a percentage of sales, compared to $0.7 million, or 20% as a percentage of sales, in the prior year period. The increase in gross margin percentage was primarily attributable to the product mix sold in different periods.

Selling, general and administrative expenses for the nine months ended September 30, 2025 increased 14% to $7.2 million compared to $6.3 million in the prior year period, and decreased as a percentage of sales from 173% of sales in the first nine months of 2024 to 96% of sales in the first nine months of 2025. The increase was primarily due to increases in salaries and benefits and legal and professional fees, slightly offset by a decrease in rent and associated expenses.

Net loss totaled $1.8 million for the nine months ended September 30, 2025, an $11.4 million improvement from $13.2 million in the prior year period. The improvement was driven by increased sales and proportional decreases in cost of sales resulting in improved gross profit, as well as improvements in other income and expense.
