RAMBUS INC.
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
1. Basis of Presentation
The accompanying Unaudited Condensed Consolidated Financial Statements include the accounts of Rambus Inc. (“Rambus” or the “Company”) and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in the accompanying Unaudited Condensed Consolidated Financial Statements.
In the opinion of management, the Unaudited Condensed Consolidated Financial Statements include all adjustments (consisting only of normal recurring items) necessary to state fairly the financial position and results of operations for each interim period presented. Interim results are not necessarily indicative of results for a full year.
Financial Statement Preparation
The Unaudited Condensed Consolidated Financial Statements have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”) applicable to interim financial information. Certain information and note disclosures included in the financial statements prepared in accordance with generally accepted accounting principles (“GAAP”) have been omitted in these interim statements pursuant to such SEC rules and regulations. The information included in this Form 10-Q should be read in conjunction with the consolidated financial statements and notes thereto in Form 10-K for the year ended December 31, 2023.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Reclassifications
Certain prior-year balances were reclassified to conform to the current year’s presentation. None of these reclassifications had an impact on reported net income or cash flows for any of the periods presented.
Significant Accounting Policies
There were no material changes to Rambus’s significant accounting policies disclosed in Note 2, “Summary of Significant Accounting Policies,” of Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.
2. Recent Accounting Pronouncements
Recent Accounting Pronouncements Not Yet Adopted
In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” This guidance requires disclosure of incremental segment information on an annual and interim basis, primarily through enhanced disclosures about significant segment expenses that are regularly provided to the chief operating decision maker. In addition, this ASU requires that all existing annual disclosures about segment profit or loss must be provided on an interim basis and clarifies that single reportable segment entities are subject to the disclosure requirement under Topic 280 in its entirety. This ASU is effective for annual reporting periods beginning after December 15, 2023, and interim reporting periods within annual reporting periods beginning after December 15, 2024. Early adoption is permitted. The amendments in this ASU should be applied on a retrospective basis. The Company is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements.
In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” This guidance requires additional disclosures related to rate reconciliation, income taxes paid and other disclosures. For each annual period presented, public business entities are required to 1) disclose specific categories in the rate reconciliation and 2) provide additional information for reconciling items that meet a quantitative threshold. In addition, this ASU requires all reporting entities to disclose on an annual basis the amount of income taxes paid disaggregated by federal, state and foreign taxes, as well as the amount of income taxes paid disaggregated by individual jurisdictions which meet a quantitative threshold. This ASU is effective for annual reporting periods beginning after December 15, 2024, with early adoption permitted for annual financial statements that have not yet been issued or made available for issuance. The
9


amendments in this ASU should be applied on a prospective basis, with retrospective application permitted. The Company is currently evaluating the impact that the adoption of this guidance will have on its consolidated financial statements.
3. Revenue Recognition
Contract Balances
The contract assets are primarily related to the Company’s fixed fee intellectual property (“IP”) licensing arrangements and rights to consideration for performance obligations delivered but not billed as of September 30, 2024.
The Company’s contract balances were as follows:
As of
(In thousands)September 30, 2024December 31, 2023
Unbilled receivables$34,357 $55,295 
Deferred revenue$19,346 $18,085 
During the nine months ended September 30, 2024, the Company recognized $16.4 million of revenue that was included in deferred revenue as of December 31, 2023. During the nine months ended September 30, 2023, the Company recognized $19.3 million of revenue that was included in deferred revenue as of December 31, 2022.
Remaining Performance Obligations
Revenue allocated to remaining performance obligations represents the transaction price allocated to the performance obligations that are unsatisfied, or partially unsatisfied, which includes unearned revenue and amounts that will be invoiced and recognized as revenue in future periods. Contracted but unsatisfied performance obligations were approximately $28.2 million as of September 30, 2024, which the Company primarily expects to recognize over the next 2 years.
4. Earnings Per Share
Basic earnings per share is calculated by dividing the net income by the weighted-average number of common shares outstanding during the period. Diluted earnings per share is calculated by dividing the earnings by the weighted-average number of common shares and potentially dilutive securities outstanding during the period. Potentially dilutive common shares consist of incremental common shares issuable upon exercise of stock options, employee stock purchases, and restricted stock and restricted stock units and shares issuable upon the conversion of convertible notes. The dilutive effect of outstanding shares is reflected in diluted earnings per share by application of the treasury stock method, or the if-converted method for the in-the-money conversion feature of the Company’s 2023 Notes (“the 2023 Notes”). This method includes consideration of the amounts to be paid by the employees, the amount of excess tax benefits that would be recognized in equity if the instrument was exercised and the amount of unrecognized stock-based compensation related to future services. No potential dilutive common shares are included in the computation of any diluted per share amount when a net loss is reported.
The following table sets forth the computation of basic and diluted net income per share:

6. Segments and Major Customers
Operating segments are based upon the Company’s internal organization structure, the manner in which its operations are managed, the criteria used by its Chief Operating Decision Maker (“CODM”) to evaluate segment performance and availability of separate financial information regularly reviewed for resource allocation and performance assessment.
The Company has determined its CODM to be the Chief Executive Officer (“CEO”). The CEO reviews financial information presented on a consolidated basis for purposes of managing the business, allocating resources, making operating decisions and assessing financial performance. On this basis, the Company is organized and operates as a single segment within the semiconductor space. As of September 30, 2024, the Company has a single operating and reportable segment.

The gross unrealized losses at September 30, 2024 and December 31, 2023 were not material in relation to the Company’s total available-for-sale portfolio. The gross unrealized losses can be primarily attributed to a combination of market conditions as well as the demand for and duration of the U.S. government-sponsored obligations and corporate bonds, commercial paper and notes. The Company reasonably believes that there is no need to sell these investments and that it can recover the amortized cost of these investments. The Company has found no evidence of impairment due to credit losses in its portfolio. Therefore, these unrealized losses were recorded in other comprehensive income (loss). The Company cannot provide any assurance that its portfolio of cash, cash equivalents and marketable securities will not be impacted by adverse conditions in the financial markets, which may require the Company in the future to record an impairment charge for credit losses which could adversely impact its financial results.

The Company’s liabilities related to earn-out liability were classified within Level 3 of the fair value hierarchy because the fair value was determined using significant unobservable inputs. The following table presents additional information about liabilities measured at fair value for which the Company utilizes Level 3 inputs to determine fair value, as of September 30, 2024 and 2023.

For the three and nine months ended September 30, 2024 and 2023, the changes in the fair value of the earn-out liability related to the 2021 acquisition of PLDA, which was subject to certain revenue targets of the acquired business for a period of three years from the date of acquisition, and which is settled annually in shares of the Company’s common stock based on the fair value of that common stock fixed at the time the Company acquired PLDA. The fair value of the earn-out liability was remeasured each quarter, depending on the acquired business’s revenue performance relative to target over the applicable period, and adjusted to reflect changes in the per share value of the Company’s common stock. The Company classified its liability for the contingent earn-out liability related to the PLDA acquisition within Level 3 of the fair value hierarchy because the fair value calculation included significant unobservable inputs, such as revenue forecast, revenue volatility, equity volatility and weighted-average cost of capital. During the three and nine months ended September 30, 2024, the Company remeasured the fair value of the earn-out liability, which resulted in reductions of $4.5 million and $5.0 million, respectively, in the Company’s Unaudited Condensed Consolidated Statements of Operations. During the three and nine months ended September 30, 2023, the Company remeasured the fair value of the earn-out liability, which resulted in a reduction of $5.7 million and additional expenses of $8.1 million, respectively, in the Company’s Unaudited Condensed Consolidated Statements of Operations. The final earn-out was achieved as of September 30, 2024 and is expected to be fully paid during the fourth quarter of 2024.
The Company monitors its investments for impairment and records appropriate reductions in carrying value when necessary. The Company monitors its investments for impairment by considering current factors, including the economic environment, market conditions, operational performance and other specific factors relating to the business underlying the investment, reductions in carrying values when necessary and the Company’s ability and intent to hold the investment for a period of time which may be sufficient for anticipated recovery in the market. Any impairment is reported under “Interest and other income (expense), net” in the Unaudited Condensed Consolidated Statements of Operations.

In 2018, the Company made an investment in a non-marketable equity security of a private company. This equity investment was accounted for under the equity method of accounting, and the Company accounted for its equity method share of the income (loss) on a quarterly basis. During the fourth quarter of 2023, the Company sold its 25.0% ownership share in the equity investment for approximately $25.0 million, which represented a gross gain on this transaction for the same amount. The gross gain was offset by transaction costs of approximately $1.1 million, resulting in a net gain of approximately $23.9 million, which was included in the Company’s Consolidated Statement of Operations for the year ended December 31, 2023. Subsequently, the Company received proceeds, net of tax, of approximately $22.8 million from this transaction during the first quarter of 2024.
During the three and nine months ended September 30, 2024 and 2023, there were no transfers of financial instruments between different categories of fair value.
9. Leases
The Company leases office space, domestically and internationally, under operating leases. The Company’s leases have remaining lease terms generally between one year and six years. Operating leases are included in operating lease right-of-use (“ROU”) assets, operating lease liabilities and long-term operating lease liabilities on the Company’s Unaudited Condensed Consolidated Balance Sheets. The Company does not have any finance leases.
The table below reconciles the undiscounted cash flows for the first five years and total of the remaining years to the operating lease liabilities recorded on the Unaudited Condensed Consolidated Balance Sheet as of September 30, 2024 (in thousands):

Operating lease costs included in research and development and selling, general and administrative costs on the Unaudited Condensed Consolidated Statements of Operations were $1.4 million and $1.3 million for the three months ended September 30, 2024 and 2023, respectively. Operating lease costs included in research and development and selling, general and administrative costs on the Unaudited Condensed Consolidated Statements of Operations were $4.0 million and $4.7 million for the nine months ended September 30, 2024 and 2023, respectively.
Cash paid for amounts included in the measurement of operating lease liabilities were $4.5 million and $5.2 million for the nine months ended September 30, 2024 and 2023, respectively.
10. Convertible Notes
The Company did not have any convertible notes outstanding as of September 30, 2024 and December 31, 2023.
During the first quarter of 2023, the holders of the remaining $10.4 million aggregate principal amount of the 2023 Notes elected to convert the notes pursuant to the original terms of the conversion feature. Accordingly, upon maturity, the Company paid $10.4 million in cash to settle the aggregate principal amount of the 2023 Notes and delivered approximately 0.3 million shares of the Company's common stock to settle the conversion spread.
16


In connection with the settlement of the conversion of the remaining 2023 Notes, the Company received 0.3 million shares of the Company’s common stock for the retirement of the remaining convertible senior note hedges and paid $10.7 million in cash for the retirement of the remaining warrants during the first quarter of 2023. Additionally, the retirement of the remaining warrants was subject to derivative accounting, resulting in a loss on fair value adjustment of derivatives of $0.2 million for the nine months ended September 30, 2023.
Interest expense related to the convertible notes for the nine months ended September 30, 2023 was immaterial.

Indemnification covers customers for losses suffered or incurred by them as a result of any patent, copyright, or other IP infringement or any other claim by any third party arising as a result of the applicable agreement with the Company. The Company generally attempts to limit the maximum amount of indemnification that the Company could be required to make under these agreements to the amount of fees received by the Company, however, this may not always be possible. The fair value of the liability as of September 30, 2024 and December 31, 2023, respectively, was not material.
