Product revenue represented 56% of total revenue versus 48% in the prior-year quarter, reflecting continued growth in memory interface chips. Royalties represented 25% versus 31%, and contract and other revenue represented 19% versus 21%.
Gross margin declined primarily because product revenue increased faster than higher-margin royalty revenue and product costs rose with increased memory interface chip volumes. Research and development expense increased to $41.9 million from $39.8 million, while sales, general and administrative expense increased to $31.0 million from $26.9 million. The increases were driven substantially by higher stock-based compensation and headcount-related costs.
Liquidity, cash flow and capital structure
- Cash and cash equivalents were $99.9 million at March 31, 2023, down from $125.3 million at December 31, 2022.
- Marketable securities were $192.3 million, producing total cash, cash equivalents and marketable securities of $292.1 million versus $313.2 million at year-end.
- Operating cash flow was $38.9 million. Investing cash flow was $(10.7) million, including $7.7 million of capital expenditures and net purchases of marketable securities. Financing cash flow was $(54.2) million.
- The remaining $10.4 million principal amount of the 1.375% convertible senior notes due 2023 was settled in cash during the quarter. Rambus also paid $10.7 million to retire related warrants. No convertible debt remained at March 31, 2023.
- Rambus had $48.7 million of specified contractual obligations, excluding leases and potentially payable unrecognized tax benefits. Operating lease liabilities totaled $32.4 million on a present-value basis.
- Management expects existing cash, investments and operating cash flow to satisfy cash needs for at least the next 12 months.
Material changes versus the prior comparable period
- Revenue increased 14.9%, led by a $15.8 million increase in product revenue from memory interface chip market-share gains.
- Royalty revenue declined $2.2 million, primarily because of the timing and structure of license renewals.
- Gross margin contracted as product mix shifted toward lower-margin product revenue and product costs increased.
- Operating income declined despite higher revenue, reflecting increased operating expenses and a $6.9 million remeasurement expense for the PLDA acquisition earn-out, compared with $1.2 million in Q1 2022.
- Net results improved substantially because Q1 2022 included a $66.5 million loss on extinguishment of debt and an $8.3 million derivative fair-value loss. Q1 2023 included only a $0.2 million derivative fair-value loss.
- Stock-based compensation increased to approximately $13.1 million from $7.8 million.
- Top-five customers represented approximately 61% of revenue versus 59% in the prior-year quarter, increasing customer-concentration risk.
Guidance, outlook, commentary and risks
Management stated that product revenue is expected to continue increasing during 2023, primarily from memory interface chips. Research and development spending is expected to remain higher as Rambus invests in semiconductor, security and other technologies, while sales, general and administrative expense is expected to remain relatively flat. The filing does not provide a clear numerical revenue or earnings forecast.
Rambus extended its patent license agreement with SK hynix by 10 years through 2034. Contracted but unsatisfied performance obligations were approximately $24.8 million at March 31, 2023, primarily expected to be recognized over the next two years.
- Revenue is concentrated: the top five customers generated approximately 61% of quarterly revenue, and four individually identified customers each represented at least 10% of revenue.
- Royalty revenue remains dependent on license renewals, customer shipment volumes, pricing, product mix and adoption of Rambus technologies.
- Product growth depends on customer orders, qualification, manufacturing capacity and supply-chain availability. Rambus relies on third-party manufacturers and suppliers.
- Semiconductor cyclicality, macroeconomic weakness, inflation, interest rates, geopolitical tensions, export controls and China-related restrictions could affect demand and supply.
- Rambus maintained a full valuation allowance on U.S. federal and California deferred tax assets. Management indicated that sustained profitability could support a possible reversal of almost all of the allowance during 2023, but no reversal was recorded in the quarter.
- Unrecognized tax benefits were approximately $169.9 million, including reserves associated with potential South Korean withholding-tax refunds; the ultimate outcome and timing are uncertain.
- Marketable securities had $2.4 million of gross unrealized losses at quarter-end. Management found no credit-loss impairment and stated it intends and is able to hold the investments for recovery.
- The company reported no material pending legal proceedings, and management concluded that disclosure controls and procedures were effective as of March 31, 2023.
Important facts for investors to verify
- Whether memory interface chip growth continues without further erosion of gross margin.
- The timing, size and terms of royalty renewals and extensions, including the economic impact of the SK hynix agreement.
- Customer concentration, order visibility and exposure to DRAM and semiconductor industry cycles.
- Supply-chain capacity, third-party manufacturing reliability and inventory requirements as product demand changes.
- The potential timing and magnitude of any U.S. deferred-tax valuation allowance reversal.
- The ultimate settlement and timing of approximately $169.9 million of unrecognized tax benefits and related South Korean tax refund claims.
- Future PLDA earn-out remeasurements, which may create additional non-cash operating expense.
- Cash deployment priorities, including the remaining authorization to repurchase approximately 9.7 million shares and potential acquisitions.
