NeoVolta Inc. (NASDAQ: NEOV) reported full-year revenue of $13.3 million for fiscal year 2026, a 58% increase on the prior year's $8.4 million, but the headline growth figure masked a dramatic fourth-quarter collapse. Q4 revenue fell to approximately $13,500, against $4.8 million in the same quarter of fiscal 2025, after changes to US federal tax law in early calendar 2026 sharply reduced demand through the residential installer channel that had historically anchored the San Diego-based company's sales.

The full-year GAAP net loss widened to $21.5 million, or $0.55 per share, from $5.0 million a year earlier. A $3.9 million provision for credit losses and bad debt expense, and a $1.1 million inventory obsolescence charge on residential stock, drove Q4's GAAP loss to $11.7 million alone. Adjusted EBITDA, a non-GAAP measure the company is disclosing for the first time, came in at negative $12.8 million for the full year. NeoVolta ended the period with $22.2 million in cash and a further $3.2 million in restricted cash, after completing a public equity offering in May 2026.

Manufacturing pivot and SK On supply deal

The strategic pivot away from residential sits at the centre of NeoVolta's fiscal 2026 narrative. The company launched NeoVolta Power LLC, an 80%-owned joint venture based in Pendergrass, Georgia, to manufacture utility-scale and commercial-and-industrial (C&I) battery energy storage systems (BESS). The Pendergrass facility received a formal opinion confirming compliance with Foreign Entity of Concern (FEOC) rules, positioning its products as eligible for the US Inflation Reduction Act's Section 48E investment tax credit. That compliance confirmation matters commercially: FEOC-clean supply chains are increasingly a prerequisite for federally incentivised storage deployments.

Announced after the fiscal year closed, a five-year collaboration with South Korean cell maker SK On is the deal investors are likely to focus on. Under a signed agreement, SK On will supply 9 gigawatt-hours (GWh) of US-manufactured lithium iron phosphate (LFP) battery cells to NeoVolta Power from 2027 through 2031. A broader framework, not yet a binding contract, contemplates an additional 9 GWh of cell supply and SK On purchasing manufactured storage packs in return, for a combined potential of 18 GWh of activity over the period. NeoVolta also signed a binding capacity reservation agreement with Infinite Grid Capital (IGC) to supply BESS for edge AI data-centre projects in northern Ontario in calendar year 2027, converting part of a previously non-binding 1.1 GWh letter of intent worth a potential $200 million.

Market context and policy read-across

NeoVolta's residential stumble is not idiosyncratic. The US residential storage market broadly contracted in early 2026 following adjustments to federal clean-energy tax incentives that reduced the economics for homeowners and installers alike. Several developers that built their early revenue base on residential retrofit are now pivoting to utility and C&I markets, where project sizes are larger, offtake agreements provide more revenue visibility, and the IRA's Section 48E credit creates a meaningful cost advantage for domestically manufactured systems.

The utility-scale BESS market is competitive and well-funded. Established players with multi-GWh order books and lower-cost Korean and Chinese cell supply dominate. NeoVolta's FEOC compliance and domestic manufacturing position it to compete for projects where supply-chain provenance is a selection criterion, but it must convert pipeline opportunities into binding orders before the Pendergrass facility scales.

Chief executive Ardes Johnson said the SK On collaboration and the growth of the utility-scale and C&I pipeline mean NeoVolta "enters fiscal year 2027 with a stronger platform to execute our growth strategy." The company has also drawn down a $20 million senior secured term loan to fund working capital during the production ramp.

Key milestones to watch in fiscal 2027 include completing the Pendergrass site acceptance test and commissioning, converting the IGC letter of intent into a binding order, and a final investment decision on a potential second production line that the company says could push site capacity toward 8 GWh per year by calendar 2028.
