FY2012 investing cash outflow was $13.0 million, primarily for manufacturing test equipment and facilities. Financing cash inflow was $51.4 million, chiefly reflecting IPO proceeds, partly offset by term-loan repayments. Enphase reported $21.2 million available to borrow under its $50 million Wells Fargo revolver, with no draw outstanding at year-end. It stated that cash and expected credit availability should fund planned operations and capital expenditures for at least 12 months.
Fourth-quarter revenue was $57.6 million, gross profit was $16.1 million and net loss was $7.7 million.
Changes versus the prior year
- Revenue grew 45%; microinverter unit sales rose 51%, from about 1.00 million to 1.51 million. Management attributed growth to the third-generation product, deeper penetration of existing customers and new customers.
- Gross margin expanded 6.1 percentage points to 25.5%, mainly from a greater share of lower-cost third-generation units and less expedited freight. Warranty estimate changes partly offset the improvement.
- Net loss widened by $5.9 million as operating expenses and interest expense increased. Operating cash use rose sharply, in part because $23.0 million of product revenue deferred from customer prepayments in 2011 was recognized and deferred revenue declined in 2012.
- Enphase completed its April 2012 IPO, receiving approximately $53.8 million net proceeds; preferred stock and convertible notes converted into common stock. It replaced prior credit arrangements, repaid Horizon term loans and entered into new Wells Fargo and Hercules facilities.
Outlook, commentary and risks
Management provided no specific revenue or earnings guidance in the supplied filing text. It plans continued geographic expansion, new products for larger commercial and utility-scale installations, and investment in product performance, efficiency and cost reduction. Management said prior infrastructure investments were intended to support higher revenue without proportionate increases in operating expenses, while also expecting continued investment in R&D and sales and marketing.
- Profitability and cash: Enphase had incurred losses every quarter since beginning operations; accumulated deficit was $127.0 million. FY2012 operating cash use was significant.
- Warranty exposure: Warranty expense included a net $7.6 million increase from estimate changes in 2012, including $10.2 million of increases related to prior-generation product performance and replacement costs, partly offset by $2.6 million of reductions. The company’s relatively short product history makes long-term warranty estimates uncertain.
- Market and policy: Demand depends partly on solar incentives, financing availability and electricity economics. The filing cites subsidy reductions, program suspensions, industry oversupply and falling solar prices as risks.
- Competition and execution: Established inverter makers and new entrants were preparing to compete in microinverters. Enphase also relies on a small number of contract manufacturers and limited-source suppliers, including for key components.
- Concentration and obligations: Two distributors together accounted for 27% of FY2012 revenue. Two customers represented 21% and 16% of year-end receivables. Purchase commitments totaled $115.6 million; $98.6 million were cancelable subject to penalties of up to $5.4 million.
- Debt and controls: Credit agreements impose restrictions and liquidity requirements; substantially all assets other than intellectual property secure the facilities. The independent auditor issued an unqualified opinion on the financial statements, but did not audit internal control over financial reporting; management reported disclosure controls were effective.
Important facts for investors to verify
- Whether revenue growth and the improved gross margin can be sustained amid declining average selling prices and stronger competition.
- Warranty claims, replacement costs and assumptions underlying the $21.3 million year-end warranty obligation.
- Cash burn, working-capital needs, revolver availability and compliance with credit-facility requirements.
- Distributor and customer concentration, collections, channel inventory and end-customer demand.
- Exposure to incentive-policy changes, especially in the United States and expanding European markets.
