____________________________

<sup>(1)</sup> &nbsp;&nbsp;&nbsp;&nbsp;See "Reconciliation of GAAP Forward Looking Estimates to Non-GAAP Forward Looking Estimates" tables included below. Note that the applicable non-GAAP measures are presented, and that revenue is solely presented on a GAAP basis.

<sup>(2)</sup> &nbsp;&nbsp;&nbsp;&nbsp;Licensing billings is an operational metric that reflects amounts invoiced to our licensing customers during the period, as adjusted for certain differences relating to advanced payments for variable licensing agreements. This metric is the same for both GAAP and non-GAAP presentations.

For the first quarter of 2023, the Company expects licensing billings to be between $61 million and $67 million. The Company also expects royalty revenue to be between $25 million and $31 million, product revenue to be between $57 million and $63 million and contract and other revenue to be between $19 million and $25 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 $104 and $100 million. Additionally, the Company expects non-GAAP operating costs and expenses to be between $87 million and $83 million. These expectations also assume non-GAAP interest and other income (expense), net, of ($1 million), tax rate of 24% and diluted share count of 110 million, and exclude stock-based compensation expense ($13 million), amortization expense ($4 million), non-cash interest expense on convertible notes ($0.1 million) and interest income related to the significant financing component from fixed-fee patent and technology licensing arrangements ($1 million).

**Conference Call**

Rambus management will discuss the results of the quarter during a conference call scheduled for 2:00 p.m. PT today. The call will be webcast and can be accessed via Rambus' website at investor.rambus.com. A replay will be available following the call on the Rambus Investor Relations website or for one week at the following numbers: (866) 813-9403 (domestic) or

(+44) 204-525-0658 (international) with ID# 579366.

**Non-GAAP Financial Information**

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 expenses, acquisition-related costs and retention bonus expense, amortization of acquired intangible assets, expense on abandoned operating leases, change in fair value of earn-out liability, non-cash interest expense 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. Reconciliation from GAAP to non-GAAP results is included in the financial statements contained in this release.

The Company's non-GAAP financial measures reflect adjustments based on the following items:

*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 period's 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.

*Expense on abandoned operating leases.* Reflects the expense on building leases that were abandoned. The Company excludes these charges because such charges are not directly related to ongoing business results and do not reflect expected future operating expenses.

*Change in fair value of earn-out liability.* This change is due to adjustments to acquisition purchase consideration. The Company excludes these adjustments because such adjustments are not directly related to ongoing business results and do not reflect expected future operating expenses.

*Non-cash interest expense on convertible notes.* The Company incurs non-cash interest expense related to its convertible notes. The Company excludes non-cash interest expense related to its convertible notes to provide more accurate comparisons of the Company's results with other peer companies and to more accurately reflect the Company's ongoing operations.

------

*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 24% for both 2022 and 2021, 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.

On occasion in the future, there may be other items, such as significant gains or losses from contingencies that the Company may exclude in deriving its non-GAAP financial measures if it believes that doing so is consistent with the goal of providing useful information to investors and management.
