GAAP revenue for the quarter was $117.9 million. The Company also had licensing billings of $63.2 million, product revenue of $50.4 million, and contract and other revenue of $20.0 million. The Company had total GAAP cost of revenue of $23.7 million and operating expenses of $64.1 million.

Cash, cash equivalents, and marketable securities as of March 31, 2024 were $391.1 million, a decrease of $34.8 million from December 31, 2023, mainly due to $50.0 million paid in connection with an accelerated share repurchase program, $37.7 million in payments of taxes on restricted stock units, offset by $39.1 million in cash provided by operating activities and $22.8 million in proceeds from the sale of a non-marketable equity security.

The Company will discuss its full revenue guidance for the second quarter of 2024 during its upcoming conference call. The following table sets forth the second quarter outlook for other measures.



(In millions)	GAAP	Non-GAAP (1)
Licensing billings (operational metric) (2)	$61 - $67	$61 - $67
Product revenue (GAAP)	$52 - $58	$52 - $58

Total operating costs and expenses	$95 - $91	$80 - $76
Interest and other income (expense), net	$3	$3
Diluted share count	109	109

For the second quarter of 2024, the Company expects licensing billings to be between $61 million and $67 million. The Company also expects royalty revenue to be between $55 million and $61 million, product revenue to be between $52 million and $58 million and contract and other revenue to be between $17 million and $23 million. Revenue is not without risk and achieving revenue in this range will require that the Company sign customer agreements for various product sales and solutions licensing, among other matters.

The Company also expects operating costs and expenses to be between $95 million and $91 million. Additionally, the Company expects non-GAAP operating costs and expenses to be between $80 million and $76 million. These expectations also assume non-GAAP interest and other income (expense), net, of $3 million, a tax rate of 22% and a diluted share count of 109 million, and exclude stock-based compensation expense of $12 million and amortization of acquired intangible assets of $3 million.

The Company’s management will discuss the results of the quarter during a conference call scheduled for 2:00 p.m. PT today. The call, audio and slides will be available online at investor.rambus.com and a replay will be available for the next week at the following numbers: (866) 813-9403 (domestic) or (+1) 929-458-6194 (international) with ID# 691469.

In the commentary set forth above and in the financial statements included in this earnings release, the Company presents the following non-GAAP financial measures: cost of product revenue, operating expenses and interest and other income (expense), net. In computing each of these non-GAAP financial measures, the following items were considered as discussed below: stock-based compensation expense, acquisition-related costs and retention bonus expense, amortization of acquired intangible assets, expense on abandoned operating leases, facility restoration costs, change in fair value of earn-out liability, loss on fair value adjustment of derivatives, net, non-cash interest expense on convertible notes and certain other one-time adjustments. The non-GAAP financial measures disclosed by the Company should not be considered a substitute for, or superior to, financial measures calculated in accordance with GAAP, and the financial results calculated in accordance with GAAP and reconciliations from these results should be carefully evaluated. Management believes the non-GAAP financial measures are appropriate for both its own assessment of, and to show investors, how the Company’s performance compares to other periods. The non-GAAP financial measures used by the Company may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies. A reconciliation from GAAP to non-GAAP results is included in the financial statements contained in this release.

Stock-based compensation expense. These expenses primarily relate to employee stock options, employee stock purchase plans, and employee non-vested equity stock and non-vested stock units. The Company excludes stock-based compensation expense from its non-GAAP measures primarily because such expenses are non-cash expenses that the Company does not believe are reflective of ongoing operating results. Additionally, given the fact that other companies may grant different amounts and types of equity awards and may use different option valuation assumptions, excluding stock-based compensation expense permits more accurate comparisons of the Company’s results with peer companies.

Acquisition-related costs and retention bonus expense. These expenses include all direct costs of certain acquisitions and the current periods’ portion of any retention bonus expense associated with the acquisitions. The Company excludes these expenses in order to provide better comparability between periods as they are related to acquisitions and have no direct correlation to the Company’s operations.

Amortization of acquired intangible assets. The Company incurs expenses for the amortization of intangible assets acquired in acquisitions. The Company excludes these items because these expenses are not reflective of ongoing operating results in the period incurred. These amounts arise from the Company’s prior acquisitions and have no direct correlation to the operation of the Company’s core business.

Income tax adjustments. For purposes of internal forecasting, planning and analyzing future periods that assume net income from operations, the Company estimates a fixed, long-term projected tax rate of approximately 22 percent and 24 percent for 2024 and 2023, respectively, which consists of estimated U.S. federal and state tax rates, and excludes tax rates associated with certain items such as withholding tax, tax credits, deferred tax asset valuation allowance and the release of any deferred tax asset valuation allowance. Accordingly, the Company has applied these tax rates to its non-GAAP financial results for all periods in the relevant years to assist the Company’s planning.
