PDF Solutions, Inc. — FY2020 Form 10-K
Reporting period: Fiscal year ended December 31, 2020. The filing also reports unaudited fourth-quarter results. Amounts below are in U.S. dollars; financial statement figures are generally in millions unless noted.
Business context
PDF Solutions sells semiconductor-industry data analytics software and services, equipment connectivity and control software, measurement systems, and related intellectual property. Revenue comes from Analytics offerings and Integrated Yield Ramp (IYR) engagements, which may include yield-linked Gainshare royalties. In 2020, the company expanded its analytics and equipment-connectivity strategy through a partnership with Advantest and its acquisition of Cimetrix.

Fourth-quarter 2020 revenue was $22.4 million, cost of revenue was $9.8 million, net loss was $33.4 million, and loss per share was $0.91. The filing does not provide a clear fourth-quarter gross-margin figure; revenue less cost of revenue implies gross profit of approximately $12.5 million.
The company reported no off-balance-sheet arrangements, undisclosed borrowings, or debt. Selected financial data lists $10.9 million of long-term obligations; balance-sheet liabilities include operating lease liabilities and long-term income taxes payable. Operating cash flow remained positive despite the reported net loss. Year-end cash and investments included $115.0 million of short-term U.S. Treasury bills; cash and cash equivalents alone were $30.3 million.
Material changes versus FY2019
- Revenue increased 3%. Analytics revenue rose 15%, reflecting higher Exensio license fees, more characterization-services work, and Cimetrix revenue; DFI revenue declined $2.6 million.
- IYR revenue declined 14%, primarily due to lower hours worked and the absence of $3.3 million of non-recurring contract-amendment revenue recognized in 2019.
- Gross margin fell three percentage points to 58%, with the prior year benefiting from non-recurring contract-amendment revenue.
- R&D expense increased 6% to $34.7 million; selling, general and administrative expense increased 24% to $32.7 million. Costs of revenue rose 10% to $36.8 million.
- Net loss widened substantially. The principal factor was a $22.3 million income-tax provision, including recognition of a full valuation allowance against U.S. deferred tax assets; the company cited a $24.2 million year-over-year increase in tax provision.
- Operating cash flow decreased $2.8 million. Investing cash outflow rose to $150.5 million, including the Cimetrix acquisition and purchases of short-term investments. Financing cash flow was $64.8 million, principally reflecting the Advantest stock issuance.
Liquidity, transactions, outlook and risks
- Capital and acquisitions: Advantest purchased 3.3 million shares for gross proceeds of $65.2 million and entered into a five-year cloud subscription with an aggregate price exceeding $50 million, subject to milestones and contractual terms. PDF Solutions acquired Cimetrix in December for approximately $35 million net of acquired cash, with $28.6 million paid by year-end and a $3.5 million holdback expected to be settled in 2021.
- Outlook: The company provided no quantified revenue or earnings guidance in the supplied filing text. Management expects opportunities from semiconductor analytics, cloud computing, Industry 4.0, equipment connectivity, and the Advantest relationship, while stating that the partnership is early-stage and its full impact is uncertain. Remaining performance obligations were approximately $108.1 million, mostly expected to be recognized over the next two years; this is not presented as guidance and is subject to change.
- COVID-19 and markets: Restrictions disrupted office operations, travel, and customer-site access and may have made sales of complex or new technologies harder. The company reported uninterrupted product and service access, but warned that the pandemic’s duration and effects remain uncertain. Semiconductor cycles, customer spending, and China-related trade and export restrictions may also affect demand and delivery.
- Concentration and collections: GlobalFoundries accounted for 23% of FY2020 revenue, down from 31% in FY2019. Two customers represented 27% of gross receivables at year-end 2020. Net accounts receivable was $34.1 million, with reserves of $1.0 million; customer payment delays and collection disputes remain risks.
- Tax and unusual items: The company recorded a full valuation allowance of approximately $41.9 million against U.S. federal and state deferred tax assets, citing cumulative losses and uncertainty about using tax attributes before expiration. The CARES Act NOL carryback generated a $1.2 million tax benefit. The tax provision materially increased the annual net loss.
- Contingencies: PDF Solutions initiated arbitration against SMIC in May 2020 to recover unpaid fees and seek future contractual payments. The matter remained ongoing; the company reported $1.1 million of related expenses and warned that further costs could be substantial. No material legal proceeding loss was accrued as of year-end.
- Technology and cybersecurity: DFI commercialization and customer adoption remain uncertain; a key customer discontinued contractual milestones or did not renew a standard DFI engagement, reducing 2020 DFI revenue. The company disclosed a cloud-installation intrusion in Q1 2020 involving a provider vulnerability, alongside continuing cybersecurity and customer-data risks.
- Capital structure and controls: The company did not repurchase shares in 2020, though a $25 million repurchase authorization was adopted. No cash dividends were paid, and none were anticipated for the foreseeable future. The independent auditor issued unqualified opinions on the financial statements and internal control over financial reporting; Cimetrix’s controls were excluded from management’s year-end ICFR assessment following its December acquisition.
