Enphase designs and sells solar microinverter systems, gateways, and cloud monitoring services.

Financial results and liquidity
- Revenue: $357.2 million, up 4% from $343.9 million in 2014. Units sold rose 19% to 3.1 million, while average selling price per watt fell about 15%.
- Profitability: Gross profit was $108.2 million and gross margin 30.3%, down from $113.0 million and 32.9%. Operating loss was $19.3 million, compared with $4.4 million in 2014. Net loss was $22.1 million, or $0.49 per share, versus a net loss of $8.1 million, or $0.19 per share.
- Fourth quarter: Revenue was $65.6 million, versus $105.2 million in Q4 2014. Gross profit was $15.7 million; operating loss was $15.2 million and net loss was $15.8 million. The filing attributes softer annual revenue growth mainly to lower selling prices and notes lower Q4 sales versus the prior-year quarter.
- Cash flow: Operating activities used $21.2 million, compared with $24.2 million generated in 2014. Investing activities used $12.5 million, primarily for equipment and software. Financing activities provided $20.6 million, chiefly from revolving-credit borrowings.
- Balance sheet and debt: Cash and equivalents were $28.5 million, down from $42.0 million; working capital was $48.9 million. Revolver borrowings were $17.0 million at a 4.3% weighted-average rate, with $27.7 million of unused borrowing capacity. Total assets were $165.5 million and stockholders’ equity was $41.4 million.
- Other metrics: Inventory increased to $40.8 million from $21.6 million, primarily amid lower Q4 sales. Warranty obligations totaled $30.5 million. Contractual obligations included $51.0 million of purchase commitments and $18.1 million of operating leases.
Changes versus prior comparable periods
- Revenue growth slowed to 4% in 2015 from 48% in 2014, despite higher unit shipments, as pricing pressure reduced average selling prices.
- Gross margin declined 2.6 percentage points. Management cited more aggressive pricing, partly offset by lower warranty expense; lower warranty expense benefited 2015 margin by 2.5 percentage points relative to 2014.
- Operating expenses rose to $127.5 million from $117.5 million, including higher R&D and sales and marketing spending. The company reported a $1.8 million reduction in sales and marketing expense from revaluing acquisition-related contingent consideration.
- Operating cash flow swung from a $24.2 million inflow to a $21.2 million outflow, with inventory growth a major use of cash. Net loss widened from $8.1 million to $22.1 million.
Outlook, risks, and unusual items
- Outlook: The filing provides no specific revenue or earnings guidance. Management said cash, expected Revolver availability, and operating cash flows were expected to meet needs for at least 12 months, while warning that missing performance targets could weaken liquidity and require additional financing.
- Business priorities: Management plans to invest in product development and cost reductions, expand geographically and into storage and energy-management offerings, and grow services. These initiatives involve execution, market-acceptance, and funding risks.
- Key risks: Continued losses and price competition; dependence on solar incentives, net-metering policies, and electricity economics; customer concentration (CED Greentech and Vivint Solar represented 17% and 12% of revenue); reliance on a small number of contract manufacturers and suppliers; long-term product warranty exposure; and seasonal, demand, inventory, and channel volatility. Vivint was pursuing a multi-sourcing strategy.
- Warranty and acquisition items: Warranty estimates were sensitive to field failure rates, claims, and replacement costs; 2014 included $8.4 million of estimate changes, while 2015 changes were small overall. The NPS acquisition earnout’s fair value fell by $1.8 million in 2015, reflecting lower-than-forecast 2015 results and revised 2016 projections.
- Contingencies and controls: The company reported no material legal proceedings and no off-balance-sheet arrangements. Management concluded disclosure controls and internal control over financial reporting were effective; the auditor did not provide an internal-control attestation.
Most important facts for investors to verify
- Whether revenue and unit growth can offset continued selling-price declines and restore gross margin.
- Whether the Q4 sales decline and operating cash outflow were temporary, and whether inventory can be converted to sales without write-downs.
- Whether liquidity remains adequate under the Revolver’s borrowing-base and minimum-liquidity covenants, given debt, purchase commitments, and ongoing losses.
- Whether warranty experience—especially for older product generations—matches management’s assumptions and recorded $30.5 million liability.
- How customer concentration, Vivint’s multi-sourcing, solar-policy changes, and dependence on outsourced manufacturing affect future demand and delivery.
