PDF Solutions, Inc. — FY2016 Form 10-K
Reporting period: Fiscal year ended December 31, 2016. The filing also reports unaudited fourth-quarter results. Amounts are in U.S. dollars.
Business context
PDF Solutions provides semiconductor design-to-manufacturing optimization and yield-improvement services, software, hardware and intellectual property. Revenue comes primarily from Design-to-silicon-yield solutions and variable Gainshare performance incentives tied to customer yield and production volumes.
Financial performance and liquidity
| Metric | FY2016 | FY2015 |
|---|---|---|
| Total revenue | $107.5 million | $98.0 million |
| Design-to-silicon-yield solutions revenue | $77.2 million | $63.8 million |
| Gainshare revenue | $30.3 million | $34.1 million |
| Gross profit / margin | $63.0 million / 59% | $59.0 million / 60% |
| Operating income | $13.0 million | $19.2 million |
| Net income | $9.1 million | $12.4 million |
| Diluted EPS | $0.28 | $0.39 |
| Operating cash flow | $2.0 million | $30.3 million |
- Fourth-quarter 2016 revenue was $28.4 million, gross profit $16.3 million and net income $2.9 million; diluted EPS was $0.09. Fourth-quarter 2015 revenue was $24.1 million, gross profit $14.0 million and net income $2.8 million.
- Research and development expense rose 44% to $27.6 million, primarily due to continued DFI solution development. Selling, general and administrative expense increased 8% to $22.1 million.
- Cash and cash equivalents were $116.8 million at year-end, versus $126.2 million a year earlier. Working capital was $151.8 million. The company reported no off-balance-sheet arrangements or undisclosed borrowings or debt.
- Cash used in investing activities was $11.3 million, primarily capital expenditures related to DFI development. The company attributed low operating cash flow in part to higher receivables and long-term unbilled contract assets; accounts receivable increased to $48.2 million from $33.4 million.
- Contractual obligations totaled $12.2 million, including $4.3 million of operating leases and $7.9 million of purchase obligations, mostly due in 2017. No cash dividends were paid.
Material changes versus prior periods
- Annual revenue rose 10% as solutions revenue increased 21%, reflecting more billable project activity, particularly in Asia, and growth in Exensio. Gainshare revenue fell 11%, mainly because of lower 28nm volumes, partly offset by higher 14nm volumes.
- Operating income declined 33% and net income declined 27%, primarily as operating expenses increased by $10.3 million, led by DFI-related R&D investment. Gross margin edged down one percentage point.
- Operating cash flow fell from $30.3 million to $2.0 million. Management cited a $14.6 million increase in accounts receivable and a $11.0 million increase in other non-current assets, mainly long-term unbilled contract amounts.
- Global Foundries accounted for 41% of FY2016 revenue and Samsung for 11%, compared with 53% and 12%, respectively, in 2015. International revenue increased to 64% of total revenue from 54%.
Outlook, commentary and risks
- Management expected leading-edge foundries to continue investing in capacity and technology during 2017, and anticipated continued growth in 14nm utilization. It expected 28nm utilization improvement to continue, while cautioning that Gainshare revenue can fluctuate with wafer volumes, pricing and other factors. The filing provides no specific revenue or earnings guidance.
- The company entered a 14nm yield-ramp engagement with a Chinese foundry in the fourth quarter, including a long-term Gainshare component. It also reported 13 new Exensio fabless and foundry customers during 2016 and a contract with its first significant OSAT customer.
- DFI’s commercialization remains uncertain: its in-line tool was still in development, and the company cautioned that customer adoption, technical performance and possible wafer damage could affect returns on its investment.
- Customer and revenue concentration are significant risks. Gainshare depends on customer production volumes and yield outcomes, and revenue recognition may be affected by customer reporting, estimates and contractual terms. The company also flagged semiconductor cyclicality, long sales cycles, competition, international operations, collection risk and reliance on specialized employees.
- Accounts receivable and days sales outstanding may rise further as the company promotes DFI in Asia. Two customers represented 55% of gross receivables at year-end.
- The company early adopted ASU 2016-09 for share-based compensation, recording a $4.9 million cumulative-effect decrease in accumulated deficit at January 1, 2016. A revised project profitability estimate increased FY2016 net income by $0.9 million, or $0.03 per diluted share.
- Management concluded disclosure controls and internal control over financial reporting were effective at year-end; the auditor issued unqualified opinions on the financial statements and internal control. No material legal proceedings were reported.
Important facts for investors to verify
- Whether the sharp decline in operating cash flow and the growth in billed and unbilled receivables reverse through customer collections.
- Whether solutions revenue growth can continue and offset volatility or further declines in Gainshare, especially given the large share of revenue from Global Foundries.
- Progress, customer adoption, costs and commercial returns for the DFI tool and related development investment.
- The terms, timing and collectability of Gainshare arrangements, unbilled contract balances and customer concentration in revenue and receivables.
- The effect of ASU 2016-09 and the forthcoming revenue-recognition standard on reported earnings, cash flows and revenue timing.
