Acorn Energy (Nasdaq: ACFN) reported Q2 2026 revenue of $2.489 million, down 29.4% from $3.525 million a year earlier, while diluted EPS fell to $0.12 from $0.28. Recurring monitoring revenue continued to grow and lifted gross margin, but a sharp decline in hardware deployments reduced gross profit and net income.
Core financial results
The revenue decline was concentrated in hardware, which fell by $1.141 million year over year. Monitoring revenue increased by $105,000, partly offsetting the hardware decline as the number of monitored endpoints continued to grow.
Gross profit declined less rapidly than revenue because monitoring carries a substantially higher margin. However, operating expenses fell only 1.0%, leaving the company with significantly lower operating income and net income.
| Metric | Q2 2026 | Q2 2025 | Year-over-year change |
|---|---|---|---|
| Revenue | $2.489 million | $3.525 million | -29.4% |
| Gross profit | $2.050 million | $2.639 million | Approx. -22.3% |
| Gross margin | 82.4% | 74.9% | +750 basis points |
| Operating expenses | $1.675 million | $1.692 million | -1.0% |
| Operating income | $0.375 million | $0.947 million | Approx. -60.4% |
| Net income attributable to stockholders | $0.294 million | $0.720 million | -59.2% |
| Diluted EPS | $0.12 | $0.28 | -57.1% |
Business performance
Monitoring and hardware moved in opposite directions during the quarter. Monitoring revenue, which is generally recognized over a service period of one year, rose 8.0%, while hardware revenue fell 51.7% because the prior-year quarter included larger deployments for a national telecom customer.
| Revenue category | Q2 2026 | Q2 2025 | Year-over-year change |
|---|---|---|---|
| Monitoring revenue | $1.425 million | $1.320 million | +8.0% |
| Hardware revenue | $1.064 million | $2.205 million | -51.7% |
| Telecom customer hardware revenue | $0.263 million | $1.338 million | Approx. -80.3% |
| Telecom customer monitoring revenue | $0.147 million | $0.102 million | Approx. +44.1% |
The national telecom customer accounted for most of the hardware decline. Its monitoring contribution increased, but the additional recurring revenue was too small to offset the reduction in deployment-related hardware sales.
Recurring revenue lifted margin, but lower hardware volume reduced profit dollars
Monitoring revenue represented approximately 57% of quarterly revenue, up from about 37% in Q2 2025. Its gross margin also increased to 95.6% from 94.6%, helping raise Acorn Energy’s consolidated gross margin to 82.4%.
The improved mix did not prevent gross profit from falling by $589,000 because total revenue declined by more than $1 million. Operating expenses decreased by only $17,000, so most of the gross-profit reduction flowed through to operating income. Quarterly stock-based compensation also increased to $99,000 from $32,000, adding pressure to reported earnings.
Cash flow and balance sheet
Cash-flow figures were reported for the first six months of 2026 rather than for the second quarter alone. Operating activities generated $277,000 during the first half, down from $900,000 in the comparable 2025 period. The decrease reflected lower earnings as well as a $257,000 reduction in deferred revenue.
Acorn Energy used $263,000 for investing activities, including $250,000 paid in the first quarter for exclusive distribution and commercialization rights related to the OMNI360 product suite. After $10,000 of financing inflows from stock-option exercises, cash increased by $24,000 during the six-month period.
At June 30, 2026, cash stood at $4.478 million, compared with $4.454 million at the end of 2025. Net working capital excluding deferred revenue increased to $6.410 million from $6.254 million, while inventory declined to $1.127 million from $1.254 million.
Management’s growth initiatives
Management expects the new partnership with Champion Power Equipment to begin contributing during the current quarter. Under the agreement, OmniMetrix remote monitoring and control will be the standard monitoring option on Champion’s aXis and fleX home standby generators, expanding Acorn Energy’s access to the residential generator market.
The company also formally launched OMNI360, a three-tier remote monitoring and site-management system for telecom towers and other critical infrastructure. Management expects a longer sales cycle because of the product’s breadth and the size of prospective customers, and it did not provide visibility into when OMNI360 could begin generating revenue.
Management expects year-over-year revenue comparisons to become more favorable after cycling through the large telecom hardware deployments recorded in 2025. It continues to target average annual revenue growth of 20% over a three- to five-year period, but did not issue quantified near-term revenue or earnings guidance.
Risks investors should monitor
- Hardware revenue remains dependent on deployment timing. The sharp reduction in purchases by one national telecom customer demonstrates how large projects can create substantial quarterly volatility.
- The higher monitoring margin may not fully offset lower sales volume. Operating expenses changed little despite the revenue decline, causing operating income to fall faster than gross profit.
- New growth initiatives have uncertain timing. Management expects the Champion partnership to contribute soon, but OMNI360 may have a longer sales process and currently has no disclosed revenue timetable.
- Cash generation weakened in the first half. Operating cash flow declined from $900,000 to $277,000 as earnings and deferred revenue fell, although the cash balance remained broadly stable.
Summary
Acorn Energy’s Q2 2026 results showed continued growth in high-margin recurring monitoring revenue, but that growth was outweighed by the timing-related decline in telecom hardware deployments. The richer revenue mix lifted gross margin, yet lower gross-profit dollars and largely stable operating expenses reduced earnings. Future performance will depend on continued endpoint growth, more normalized hardware comparisons, and the commercialization pace of the Champion partnership and OMNI360.
