BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

6 Months Ended

Jun. 30, 2024

BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information and do not include all disclosures normally required in annual consolidated financial statements prepared in accordance with GAAP. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2023 and the related notes included in the Company’s Form 10-K filed on February 20, 2024 (2023 Form 10-K) with the U.S. Securities and Exchange Commission (SEC). The December 31, 2023 condensed consolidated balance sheet was derived from the audited consolidated financial statements as of that date. In management’s opinion, the unaudited interim consolidated financial statements have been prepared on the same basis as the annual financial statements and reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the unaudited condensed consolidated financial statements.

The operating results for the three and six months ended June 30, 2024 are not necessarily indicative of the results to be expected for the full year or any other future interim or annual period.

Principles of Consolidation

The unaudited condensed consolidated financial statements include the accounts of Arteris, Inc. and its wholly-owned subsidiaries. All intercompany transactions and accounts have been eliminated.

Use of Estimates

The preparation of the unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Such estimates relate to, among others, revenue recognition, the useful lives of assets, assessment of recoverability of property, plant and equipment, fair value of investments, impairment of the equity method investment, fair values of goodwill and other intangible assets, including impairments, leases, allowances for doubtful accounts, deferred tax assets and related valuation allowance, stock-based compensation, potential reserves relating to litigation and tax matters, collectability of certain receivables, fair value and amortization of deferred income, as well as other accruals or reserves. Actual results could differ from those estimates and such differences may be material to the unaudited condensed consolidated financial statements.

Cash, Cash Equivalents and Restricted Cash

The Company considers all highly liquid investments purchased with original maturities of three months or less from the purchase date to be cash equivalents. The Company’s cash equivalents include deposits in money market accounts which were unrestricted as to withdrawal or use and are stated at fair value. As of June 30, 2024, cash and cash equivalents consisted primarily of checking, savings, money market accounts and highly liquid investments with original maturities of three months or less. Interest earned on cash and cash equivalents is included in other income (expense), net in the unaudited consolidated statements of loss.

As of both June 30, 2024 and December 31, 2023, the Company’s long-term restricted cash balance was $0.4 million, primarily related to a letter of credit for its facility lease agreement. Restricted cash, noncurrent is included in other assets on the unaudited condensed consolidated balance sheets.

Concentrations of Credit Risk

Financial instruments that potentially subject us to concentration of credit risk consist of cash and cash equivalents, investments and accounts receivable. Cash is currently held in three financial institutions that the Company believes are creditworthy. Cash held at these financial institutions generally exceed federally insured limits. The Company is exposed to credit risk in the event of default by the financial institution holding its cash, cash equivalents, and investments to the extent recorded in the balance sheet. The Company has not experienced any losses to date related to these concentrations.

The Company’s accounts receivable are derived principally from revenue earned from customers located in Americas, Europe, Middle East and Asia Pacific regions.

Accounts receivable from the Company’s major customers representing 10% or more of total accounts receivable was as follows:


	As of
	June 30, 2024		December 31, 2023
Customer A	27	%	15	%
Customer B	*		26	%

* Customer accounted for less than 10% of total accounts receivable at period end.

Revenue from the Company’s major customers representing 10% or more of total revenue was as follows:


	Three Months Ended June 30,			Six Months Ended June 30,
	2024		2023	2024		2023
Customer A	14	%	*	14	%	*

* Customer accounted for less than 10% of total revenue during the period.

Stock-based Compensation

The Company measures equity classified stock-based awards, including stock options and RSUs granted to employees, directors, and non-employees based on the estimated fair values of the awards on the date of the grant. Stock-based compensation expense for awards with service-based vesting only is recognized on a straight-line basis over the requisite service period which is generally the vesting period of such awards, as a component of operating expenses within the consolidated statements of income (loss). For awards that include performance conditions stock-based compensation expense is recognized on a graded vesting basis over the requisite service period. Compensation expense is not recognized until the performance condition becomes probable. The Company accounts for forfeitures related to these awards as they occur.

The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model. This valuation model for stock-based compensation expense requires the Company to make assumptions and judgments about the variables used in the calculation including the expected term, the volatility of the Company’s common stock, and an assumed risk-free interest rate.

The fair value of RSUs granted is measured as the fair value per share of the Company’s common stock on the date of grant.

The Company adopted the 2021 Employee Stock Purchase Plan (the 2021 ESPP) effective on October 26, 2021. The first offering under the 2021 ESPP began on May 22, 2024. Eligible employees are entitled to purchase common stock at the end of six-month offering periods, by means of limited payroll deductions, at a 15% discount from the fair market value of the common stock as of specific dates.

The fair value of shares of common stock to be issued under the 2021 ESPP is estimated using the Black-Scholes option pricing model. Stock-based compensation expense for ESPP awards is recognized on a straight-line basis over the term of each ESPP offering period.

Significant Accounting Policies

There have been no significant changes to the Company’s significant accounting policies during the six months ended June 30, 2024 from those disclosed in the annual consolidated financial statements for the year ended December 31, 2023.

Recent Accounting Pronouncements

Recently Issued Accounting Pronouncements

In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, which amends the guidance in ASC 740, Income Taxes. This ASU is intended to improve the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. It also includes certain other amendments to improve the effectiveness of income tax disclosures. This ASU is effective for fiscal years beginning after December 15, 2024. Adoption is either prospectively or retrospectively, the Company will adopt this ASU on a prospective basis. The Company is currently evaluating the impact of adopting this ASU on its consolidated financial statements and disclosures.

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires disclosure of incremental segment information on an annual and interim basis. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, and requires retrospective application to all prior periods presented in the financial statements. The Company is currently evaluating the impact of adopting this ASU on its consolidated financial statements and disclosures.

Share-Based Payment Arrangement [Abstract]

STOCK-BASED COMPENSATION

Restricted Stock Units and Awards

The following table summarizes the restricted stock unit activities under the Company’s 2016 Incentive Plan, the 2021 Incentive Plan and the 2022 Employment Inducement Incentive Plan:


	Restricted Stock Units
	Number of Shares	Weighted-Average Grant Date Fair Value

Unvested—December 31, 2023	5,732,950	$	6.56
Granted	2,197,402	$	7.30
Vested	(1,139,835)	$	6.61
Canceled	(535,587)	$	6.14
Unvested—June 30, 2024	6,254,930	$	6.85

The total grant-date fair value of restricted stock units vested was $8.0 million and $6.9 million during the six months ended June 30, 2024 and 2023, respectively.

As of June 30, 2024, there was $36.2 million of unamortized stock-based compensation cost related to unvested restricted stock units, which is expected to be recognized over a weighted-average period of 2.8 years.

2021 Employee Stock Purchase Plan

The Company adopted the 2021 ESPP effective on October 26, 2021. The 2021 ESPP enables eligible employees of the Company to purchase shares of common stock at a discount to fair market value. The 2021 ESPP provides for six-month offering periods beginning May 22 and November 22 of each year, and each offering period will consist of a six-month purchase period. The first offering period began May 22, 2024 and will end on November 21, 2024. As of June 30, 2024, 1,643,749 shares of common stock were available for future issuance under the 2021 ESPP.

On each purchase date, eligible employees will purchase the shares at a price per share equal to 85% of the lesser of (1) the fair market value of our stock on the offering date or (2) the fair market value of our stock on the purchase date.

As of June 30, 2024, there was $0.2 million of unamortized stock-based compensation cost related to ESPP, which is expected to be recognized over a weighted average period of 0.4 years.

The fair value of shares of common stock to be issued under the 2021 ESPP is estimated using the Black-Scholes option pricing model on the first day of the offering period. The Company determines valuation assumptions for Black-Scholes as follows:

Risk-Free Interest Rate—The Company bases the risk-free interest rate used in the Black-Scholes option-pricing model on the implied yield available on US Treasury zero coupon issues with an equivalent expected term of the options for each option group.

Expected Term—The expected term represents the period that the Company’s stock-based awards are expected to be outstanding. The expected term assumption is based on the simplified method. The Company expects to continue using the simplified method until sufficient information about the Company’s historical behavior is available.

Volatility—The Company determines the price volatility factor based on the historical volatility of the Company’s common stock.

Dividend Yield—The Company has never declared or paid any cash dividend and does not currently plan to pay a cash dividend in the foreseeable future. Consequently, the Company used an expected dividend yield of zero.

The following table summarizes the ESPP valuation assumptions:


						Three Months Ended June 30,
						2024
Expected volatility						74.4%
Expected term (in years)						0.5
Risk-free interest rate						5.4%
Expected dividend yield						0%

Stock-based Compensation

Stock-based compensation expense is recorded on a departmental basis, based on the classification of the award holder. The following table presents the amount of stock-based compensation related to stock-based awards to employees on the Company’s unaudited condensed consolidated statements of loss (in thousands):


	Three Months Ended June 30,				Six Months Ended June 30,
	2024		2023		2024		2023

The following table provides information about accounts receivable, net, contract assets and deferred revenue (in thousands):


	As of
	June 30, 2024		December 31, 2023
Accounts receivable, net	$	8,947	$	12,003
Contract assets, current portion	$	232	$	312

The Company recognized revenue of $11.5 million and $8.9 million for the three months ended June 30, 2024 and 2023, respectively, and $20.6 million and $16.5 million for the six months ended June 30, 2024 and 2023, respectively, that was included in the deferred revenue balance at the beginning of the respective periods.

As of June 30, 2024, non-cancelable contracted but unsatisfied or partially satisfied performance obligations that have not yet been recognized is $75.5 million which includes deferred revenue, amounts that will be invoiced and recognized as revenues in future periods and Flexible Spending Accounts (FSA) commitments, from customers where actual product selection and quantities of specific products are to be determined by customers at a future period. The Company expects to recognize $43.1 million of this balance over the next 12 months and the remainder thereafter. FSA commitments amounted to $5.6 million and $6.2 million as of June 30, 2024 and December 31, 2023, respectively. The Company has elected to exclude the potential future royalty receipts from these amounts.

Costs of Obtaining a Contract with a Customer

Incremental costs of obtaining a contract with a customer consist primarily of direct sales commissions incurred upon execution of the contract. These costs are required to be capitalized under ASC 340-40, Other Assets and Deferred Costs—Contracts With Customers, and amortized over the license term. As direct sales commissions paid for term extensions are commensurate with the amounts paid for initial contracts, the deferred incremental costs for initial contracts and for term extensions are recognized over the respective contract terms. Total capitalized direct commission costs were as follows (in thousands):


	As of
	June 30, 2024		December 31, 2023
Short-term commission capitalized in prepaid expenses and other current assets	$	2,248	$	2,408

INCOME TAXES	6 Months Ended
INCOME TAXES	Jun. 30, 2024
Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company’s effective tax rate was (8.2)% and (4.9)% for the six months ended June 30, 2024 and 2023, respectively. The Company’s income tax provision was $1.3 million and $0.9 million for the six months ended June 30, 2024 and 2023, respectively. The change in forecasted foreign withholding tax, changes in the geographic mix of worldwide earnings which are taxed at different rates, and the impact of losses in jurisdictions with full valuation allowances, has resulted in an increase in the income tax provision for the period ended June 30, 2024 compared to the period ended June 30, 2023. The Company’s management continuously evaluates the need for a valuation allowance and, as of June 30, 2024, concluded that a full valuation allowance on its federal, state, and certain foreign jurisdictions deferred tax assets was still appropriate. As of June 30, 2024 and 2023, the Company’s gross liability for unrecognized tax benefits was $3.5 million and $2.6 million, respectively. The Company’s practice is to recognize interest and/or penalties related to income tax matters in income tax expense. As of June 30, 2024 and 2023, the Company had no accrued interest or penalties related to its unrecognized tax benefits. If any unrecognized tax benefits are realized, it would not result in any income tax benefit as the Company currently has a full valuation allowance against the deferred tax assets in which there is currently an uncertain tax benefit.

- Definition

The entire disclosure for income tax.

BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
	Jun. 30, 2024
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) for interim financial information and do not include all disclosures normally required in annual consolidated financial statements prepared in accordance with GAAP. Accordingly, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2023 and the related notes included in the Company’s Form 10-K filed on February 20, 2024 (2023 Form 10-K) with the U.S. Securities and Exchange Commission (SEC). The December 31, 2023 condensed consolidated balance sheet was derived from the audited consolidated financial statements as of that date. In management’s opinion, the unaudited interim consolidated financial statements have been prepared on the same basis as the annual financial statements and reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the unaudited condensed consolidated financial statements. The operating results for the three and six months ended June 30, 2024 are not necessarily indicative of the results to be expected for the full year or any other future interim or annual period.
Principles of Consolidation	Principles of Consolidation The unaudited condensed consolidated financial statements include the accounts of Arteris, Inc. and its wholly-owned subsidiaries. All intercompany transactions and accounts have been eliminated.
Use of Estimates	Use of Estimates The preparation of the unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Such estimates relate to, among others, revenue recognition, the useful lives of assets, assessment of recoverability of property, plant and equipment, fair value of investments, impairment of the equity method investment, fair values of goodwill and other intangible assets, including impairments, leases, allowances for doubtful accounts, deferred tax assets and related valuation allowance, stock-based compensation, potential reserves relating to litigation and tax matters, collectability of certain receivables, fair value and amortization of deferred income, as well as other accruals or reserves. Actual results could differ from those estimates and such differences may be material to the unaudited condensed consolidated financial statements.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash The Company considers all highly liquid investments purchased with original maturities of three months or less from the purchase date to be cash equivalents. The Company’s cash equivalents include deposits in money market accounts which were unrestricted as to withdrawal or use and are stated at fair value. As of June 30, 2024, cash and cash equivalents consisted primarily of checking, savings, money market accounts and highly liquid investments with original maturities of three months or less. Interest earned on cash and cash equivalents is included in other income (expense), net in the unaudited consolidated statements of loss. As of both June 30, 2024 and December 31, 2023, the Company’s long-term restricted cash balance was $0.4 million, primarily related to a letter of credit for its facility lease agreement. Restricted cash, noncurrent is included in other assets on the unaudited condensed consolidated balance sheets.
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject us to concentration of credit risk consist of cash and cash equivalents, investments and accounts receivable. Cash is currently held in three financial institutions that the Company believes are creditworthy. Cash held at these financial institutions generally exceed federally insured limits. The Company is exposed to credit risk in the event of default by the financial institution holding its cash, cash equivalents, and investments to the extent recorded in the balance sheet. The Company has not experienced any losses to date related to these concentrations. The Company’s accounts receivable are derived principally from revenue earned from customers located in Americas, Europe, Middle East and Asia Pacific regions.
Stock-based Compensation	Stock-based Compensation The Company measures equity classified stock-based awards, including stock options and RSUs granted to employees, directors, and non-employees based on the estimated fair values of the awards on the date of the grant. Stock-based compensation expense for awards with service-based vesting only is recognized on a straight-line basis over the requisite service period which is generally the vesting period of such awards, as a component of operating expenses within the consolidated statements of income (loss). For awards that include performance conditions stock-based compensation expense is recognized on a graded vesting basis over the requisite service period. Compensation expense is not recognized until the performance condition becomes probable. The Company accounts for forfeitures related to these awards as they occur. The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model. This valuation model for stock-based compensation expense requires the Company to make assumptions and judgments about the variables used in the calculation including the expected term, the volatility of the Company’s common stock, and an assumed risk-free interest rate. The fair value of RSUs granted is measured as the fair value per share of the Company’s common stock on the date of grant. The Company adopted the 2021 Employee Stock Purchase Plan (the 2021 ESPP) effective on October 26, 2021. The first offering under the 2021 ESPP began on May 22, 2024. Eligible employees are entitled to purchase common stock at the end of six-month offering periods, by means of limited payroll deductions, at a 15% discount from the fair market value of the common stock as of specific dates. The fair value of shares of common stock to be issued under the 2021 ESPP is estimated using the Black-Scholes option pricing model. Stock-based compensation expense for ESPP awards is recognized on a straight-line basis over the term of each ESPP offering period.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Issued Accounting Pronouncements In December 2023, the FASB issued ASU 2023-09, Improvements to Income Tax Disclosures, which amends the guidance in ASC 740, Income Taxes. This ASU is intended to improve the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. It also includes certain other amendments to improve the effectiveness of income tax disclosures. This ASU is effective for fiscal years beginning after December 15, 2024. Adoption is either prospectively or retrospectively, the Company will adopt this ASU on a prospective basis. The Company is currently evaluating the impact of adopting this ASU on its consolidated financial statements and disclosures. In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which requires disclosure of incremental segment information on an annual and interim basis. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, and requires retrospective application to all prior periods presented in the financial statements. The Company is currently evaluating the impact of adopting this ASU on its consolidated financial statements and disclosures.
Fair Value Measurements	Assets Measured and Recorded at Fair Value on a Non-Recurring Basis Equity method investments, and certain non-financial assets, such as intangible assets are remeasured at fair value only if an impairment or observable price adjustment is recognized in the current period. Financial Instruments Not Recorded at Fair Value on a Recurring Basis Financial instruments not recorded at fair value on a recurring basis include vendor financing arrangements. The carrying value of the vendor financing agreements was $2.8 million and $3.4 million as of June 30, 2024 and December 31, 2023, respectively. The Company’s vendor financing arrangements are classified within Level 2 because these borrowings are not actively traded and have a variable interest rate structure based upon the Company’s incremental borrowing rate. The estimated fair values of these financial instruments approximate their carrying values. Money market funds are highly liquid investments and are actively traded. The fair value is based on quoted prices for identical assets in active markets and therefore classified as Level 1 of the fair value hierarchy. The Company’s other investments are considered Level 2 financial instruments as their fair values are determined using inputs that are directly or indirectly observable in active or less active markets. There were no transfers between levels during the periods presented.

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENTS

Assets Measured and Recorded at Fair Value on a Non-Recurring Basis

Equity method investments, and certain non-financial assets, such as intangible assets are remeasured at fair value only if an impairment or observable price adjustment is recognized in the current period.

Financial Instruments Not Recorded at Fair Value on a Recurring Basis

Financial instruments not recorded at fair value on a recurring basis include vendor financing arrangements. The carrying value of the vendor financing agreements was $2.8 million and $3.4 million as of June 30, 2024 and December 31, 2023, respectively. The Company’s vendor financing arrangements are classified within Level 2 because these borrowings are not actively traded and have a variable interest rate structure based upon the Company’s incremental borrowing rate. The estimated fair values of these financial instruments approximate their carrying values.

Financial Instruments Recorded at Fair Value on a Recurring Basis

The following tables summarize the Company’s financial assets measured at fair value on a recurring basis by level within the fair value hierarchy (in thousands):

Money market funds are highly liquid investments and are actively traded. The fair value is based on quoted prices for identical assets in active markets and therefore classified as Level 1 of the fair value hierarchy.

The Company’s other investments are considered Level 2 financial instruments as their fair values are determined using inputs that are directly or indirectly observable in active or less active markets. There were no transfers between levels during the periods presented.

Earnings Per Share [Abstract]

NET LOSS PER SHARE

The following table presents the calculation of basic and diluted net loss per share attributable to common stockholders (in thousands, except share and per share data):


	Three Months Ended June 30,				Six Months Ended June 30,
	2024		2023		2024		2023
Numerator:
Net loss	$	(8,344)	$	(9,165)	$	(17,747)	$	(18,175)
Denominator:
Weighted-average shares outstanding, basic and diluted	38,476,934		35,250,157		38,092,996		34,925,800
Net loss per share, basic and diluted	$	(0.22)	$	(0.26)	$	(0.47)	$	(0.52)

Since the Company was in a loss position for all periods presented, the diluted earnings per share is equal to the basic earnings per share as the effect of potentially dilutive securities would have been antidilutive.

The following table summarizes the potentially dilutive securities that were excluded from the calculation of diluted earnings per share because they would be anti-dilutive:

COMMITMENTS AND CONTINGENCIES	Jun. 30, 2024
Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Letter of Credit—In conjunction with the execution of the operating lease for the Company’s new headquarter facility, a letter of credit in the amount of $0.4 million was issued and outstanding as of both June 30, 2024 and December 31, 2023. No draws have been made under such letter of credit. Indemnifications—The Company often enters into limited indemnification provisions in license agreements in the ordinary course of the Company’s licensing business. Pursuant to these provisions, which are often inserted into license agreements in the semiconductor IP and software licensing industries, the Company agrees to indemnify, hold harmless, and reimburse the indemnified parties up to a capped amount for losses suffered or incurred by such indemnified parties due to third-party claims if such claims are determined to be caused by the Company. The term of these indemnification provisions is generally either for a term of years or perpetual, in each case beginning on the execution date of the agreement. The Company has also agreed to indemnify under indemnity agreements with its directors and officers, to the extent legally permissible, against liabilities incurred in connection with any action in which such individual may be involved by reason of such individual being or having been a director or officer, other than certain liabilities arising from willful misconduct of the individual. The Company has incurred no actual payment obligations from these above-noted indemnification provisions and director and officer indemnity agreements for the three and six months ended June 30, 2024 and 2023 and the unaudited condensed consolidated financial statements do not include liabilities for any potential indemnity-related obligations as of June 30, 2024 and December 31, 2023. Legal—The Company has been and will continue to be subject to legal proceedings and claims. In the normal course of business, the Company may receive inquiries or become involved in legal disputes regarding such litigation matters. The resolution of these matters often develops over time and expectations can change as a result of new findings, rulings, appeals or settlement arrangements. These matters are subject to inherent uncertainties and management’s view of these matters may change in the future. Pursuant to ASC 450, Contingencies, the Company makes a provision for a liability relating to legal matters when it is both probable that a liability has been incurred, and the amount of the loss can be reasonably estimated. These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, estimated settlements, legal rulings, advice of legal counsel and other information and events pertaining to a particular matter. In December 2022, the Company received notice of a complaint filed against the Company and another defendant in the semiconductor industry, by Network System Technologies, LLC (NST) in the United States District Court for the Western District of Texas. Additional complaints were filed in the Eastern District of Texas against certain companies, including some customers of the Company, asserting among other things patent infringement seeking damages and injunctive relief. On June 10, 2024, the Company and NST jointly moved for an order to stay all deadlines against the Company in the Western District of Texas, except for deadlines relating to a discovery motion brought by NST. The court in the Western District of Texas signed the order on June 11, 2024. After NST’s discovery motion has been resolved, NST and Arteris will file a stipulation of dismissal. The Company will continue to monitor this matter. Significant judgement is required in both the determination of probability and determination as to whether a loss is reasonably estimable. Intellectual property claims are inherently unpredictable and may have a material adverse effect on the Company’s financial position, results of operations, or cash flows. Due to the inherent uncertainties and complex technical issues arising from this or any intellectual property litigation, the Company cannot predict or guarantee any result of, and cannot reasonably estimate liability if any, or range of loss that could result from such intellectual property litigation. Future revisions to such estimates could materially impact the Company’s results. The Company has no material contractual noncancelable commitments as of both June 30, 2024 and December 31, 2023.
