Business Context and Reporting Period
Rambus Inc. filed an unaudited Form 10-Q for the quarter ended March 31, 2022. The company operates as a single semiconductor segment, providing memory interface chips, silicon IP, security IP, patent licensing and related engineering services. Management cited continued demand for memory interface chips, silicon IP design wins and stable royalty revenue.

| Product revenue | $48.0 million | $30.8 million | Up 55.8% |
| Royalty revenue | $30.5 million | $28.9 million | Up 5.6% |
| Contract and other revenue | $20.6 million | $10.7 million | Up 91.9% |
| Gross profit | $76.7 million | $53.0 million | Up 44.5% |
| Gross margin | 77.4% | 75.4% | Up 2.0 points |

| Net income (loss) | $(66.2) million | $(2.6) million | Declined |
| Net loss per diluted share | $(0.60) | $(0.02) | Declined |
| Cash flow from operations | $42.6 million | $39.5 million | Up $3.2 million |
The substantial net loss primarily reflected a $66.5 million loss on extinguishment of debt and an $8.3 million loss on the fair-value adjustment of derivatives associated with the partial repurchase of convertible notes. Excluding these unusual financing-related items, operating performance improved materially.
- Research and development expense was $39.8 million, up from $32.4 million, reflecting higher headcount, consulting, development tools and prototyping costs.
- Sales, general and administrative expense was $26.9 million, up from $23.6 million.
- Stock-based compensation expense was $7.8 million.
- Cash, cash equivalents and marketable securities totaled $343.7 million at March 31, 2022, compared with $485.6 million at December 31, 2021.
- Cash and cash equivalents increased to $179.1 million from $107.9 million, while marketable securities declined to $164.6 million from $377.7 million.
- Total assets were $1.06 billion and stockholders’ equity was $793.1 million at quarter-end.
Debt, Liquidity and Capital Allocation
In March 2022, Rambus repurchased approximately $123.1 million principal amount of its 1.375% convertible senior notes due 2023 for approximately $199.1 million in cash. Approximately $107.9 million of principal was settled by March 31, with the remaining $15.2 million settled on April 1. The remaining notes had a carrying value of $73.9 million at March 31, 2022, including the conversion premium associated with the unsettled portion.
- Financing activities used $175.9 million of cash, including $174.5 million for the note repurchase and $55.1 million for warrant retirement, partly offset by $72.4 million received from retiring related note hedges.
- Investing activities provided $204.8 million, primarily from sales and maturities of marketable securities.
- Management stated that existing liquidity and operating cash flow should meet cash needs for at least the next 12 months and that it did not anticipate liquidity constraints from the remaining notes, which were expected to mature in February 2023.
- The company had authorization to repurchase approximately 12.9 million additional common shares, but made no share repurchases under the program during the quarter.
Material Changes Versus the Prior Comparable Period
- Revenue increased $28.7 million, led by memory interface chip sales and higher Silicon IP-related contract revenue.
- Product revenue rose to 48% of total revenue from 44%; royalty revenue declined to 31% from 41%; contract and other revenue increased to 21% from 15%.
- Gross margin improved to 77.4% from 75.4%, while operating expenses as a percentage of revenue declined to 69.0% from 80.3%.
- Operating results shifted from a $3.5 million loss to an $8.3 million profit before financing-related charges.
- Net loss widened substantially because of the convertible-note repurchase, derivative valuation and debt extinguishment charges.
- Rambus adopted ASU 2020-06 on January 1, 2022, which reduced the reported convertible-debt discount and is expected to reduce future non-cash interest expense.
- Unbilled receivables totaled $225.1 million at March 31, 2022, down from $258.6 million at December 31, 2021. Contracted but unsatisfied performance obligations were approximately $27.0 million, primarily expected to be recognized over the next two years.
Outlook, Commentary, Risks and Unusual Items
- Management expected product revenue to continue increasing in 2022, primarily from memory interface chips, but identified customer demand, manufacturing capacity and supply-chain availability as constraints.
- Research and development expense was expected to increase as Rambus invests in semiconductor, security and other technologies; SG&A was expected to remain relatively flat in the near term.
- Royalty revenue is expected to fluctuate based on license renewals, new agreements, customer shipment volumes, pricing and product mix.
- Revenue is concentrated: the top five customers represented approximately 59% of revenue in both first quarters, and one customer represented 25% of Q1 2022 revenue.
- International customers generated approximately 44% of Q1 2022 revenue, increasing exposure to foreign markets, trade restrictions, taxation and geopolitical conditions.
- COVID-19 variants, semiconductor supply constraints, component availability, inflation, rising wages and third-party manufacturing disruptions could affect shipments, costs and customer demand.
- The company maintained a full valuation allowance on U.S. federal and California deferred tax assets. Unrecognized tax benefits totaled approximately $151.4 million, including amounts related to potential South Korean withholding-tax refunds that remain fully reserved.
- Rambus reported no material pending legal proceedings and stated that ordinary-course litigation was not expected to materially affect the business, although IP, indemnification and regulatory risks remain significant.
- On May 5, 2022, Rambus announced an agreement to acquire Hardent, Inc. for approximately $20 million CAD in cash, subject to customary closing conditions and expected to close in Q2 2022. The acquisition is intended to accelerate CXL processing solutions for data centers.
- Disclosure controls and procedures were evaluated as effective as of March 31, 2022, with no material changes to internal control over financial reporting identified during the quarter.
Investor Verification Points
- Verify the sustainability of memory interface chip growth and the company’s ability to secure sufficient wafer, packaging and manufacturing capacity.
- Track renewal timing and terms for major royalty agreements, including the Samsung license scheduled to expire on September 30, 2023.
- Assess cash requirements and refinancing or repayment plans for the remaining convertible notes due in 2023.
- Reconcile cash generation with the significant reduction in total cash and marketable securities following the debt and warrant transactions.
- Monitor customer concentration, unbilled receivables and collection timing under fixed-fee licensing arrangements.
- Evaluate the impact of the Hardent acquisition and continued integration of the AnalogX and PLDA acquisitions.
- Review potential tax exposures, including the approximately $151.4 million of unrecognized tax benefits and the uncertain South Korean refund claims.
