- Revenue increased 7%; microinverter units sold rose 8% to approximately 1.625 million, while average selling prices continued to decline.
- Gross margin improved 3.5 percentage points, primarily from lower unit costs and a richer accessories mix. Warranty estimate changes reduced 2013 gross margin by approximately 4.4 percentage points.
- Fourth-quarter revenue was $67.1 million, gross profit $21.5 million, and net loss $2.8 million, or $0.07 per share.
- Year-end cash and cash equivalents were $38.2 million; working capital was $57.1 million; total assets were $116.7 million. Debt was $8.7 million, down from $11.1 million.
- The $50 million revolving facility was undrawn, with approximately $22.4 million available under its borrowing base at year-end. Management said cash and expected revolver availability should cover planned needs for the next 12 months.
Changes, outlook, and risks
Net loss narrowed by $12.3 million from 2012. Operating cash use also fell sharply, with working-capital changes and non-cash charges offsetting much of the loss. Sales and marketing expense rose 20% as the company expanded customer support and entered Australia; research and development and general and administrative expenses declined modestly.
Enphase provided no specific revenue or earnings guidance in the supplied filing text. Management planned continued investment in research and development, geographic expansion, larger commercial and utility-scale products, and cost and efficiency improvements. It expected existing cash and available credit to fund anticipated needs for at least 12 months.
- Warranty exposure: Warranty obligations were $30.4 million. Updated second-generation failure estimates drove $19.5 million of additional warranty expense in 2013; the company’s long-term warranties extend up to 25 years.
- Customer concentration: Three customers represented 15%, 14%, and 11% of 2013 revenue. Two customers accounted for 16% and 10% of year-end receivables.
- Market and policy: Demand depends partly on solar incentives, electricity prices, financing availability, and utility rules. Incentive reductions and policy uncertainty affected several markets, including Europe and Australia.
- Competition and execution: New microinverter competitors, falling selling prices, product reliability, demand forecasting, and reliance on a small number of contract manufacturers and suppliers could pressure results.
- Commitments and financing: Contractual obligations totaled $112.3 million, including $87.6 million of purchase commitments. Of the purchase commitments, $72.5 million were cancelable subject to penalties of up to $5.6 million. Credit facilities impose covenants and asset security.
The auditor issued an unqualified opinion on the financial statements. Management concluded internal control over financial reporting was effective; the auditor was not engaged to opine on internal control.
Important facts for investors to verify
- Whether microinverter failure and warranty-claim experience supports the assumptions behind the $30.4 million warranty liability.
- Whether unit growth and manufacturing cost reductions can offset falling average selling prices and rising competition.
- How customer concentration, distributor ordering patterns, and receivable exposure evolve.
- Whether incentive and regulatory changes affect demand in the United States, Europe, and Australia.
- Available borrowing capacity and compliance with liquidity requirements, alongside scheduled debt payments and purchase commitments.
