Report of Independent Registered Public Accounting Firm


Report of Independent Registered Public Accounting Firm Shareholders and Board of Directors Cerebras Systems Inc. Sunnyvale, California Opinion on the Consolidated Financial Statements We have audited the accompanying consolidated balance sheets of Cerebras Systems Inc. (the “Company”) as of December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive loss, changes in redeemable convertible preferred stock and stockholders’ deficit, and cash flows for each of the years then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2023 and 2022, and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America. Basis for Opinion These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion. /s/ BDO USA, P.C. We have served as the Company’s auditor since 2020. San Jose, California June 17, 2024 F-2

Notes to Consolidated Financial Statements


CEREBRAS SYSTEMS INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Note 1 – Nature of Operations Cerebras Systems Inc. (the “Company” or “Cerebras”) was incorporated in Delaware in April 2016. Cerebras is an enterprise artificial intelligence (“AI”) company that designs and deploys an AI compute platform, purpose built for accelerating AI’s most complex workloads. The Company’s Wafer-Scale Engine (“WSE”), a chip encompassing an entire silicon wafer—specifically designed to tackle the computational demands of Generative AI (“GenAI”) applications. The Company architects AI systems, utilizing WSE, and the integrated software connects these systems into a cluster to form supercomputers. The AI compute platform is designed to reduce training times and inference latencies, while reducing programming complexity. The Company leverages this technology to train AI models in collaboration with its customers. Since its inception, Cerebras Systems Inc. has dedicated resources to research and development activities that support its current projects and future development efforts. The Company is headquartered in Sunnyvale, California.

Note 2 – Basis of Presentation and Liquidity These consolidated financial statements are presented in U.S. dollars and have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). The consolidated financial statements include the accounts and operations of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated upon consolidation. Certain amounts reported in the prior year financial statements have been reclassified to conform to the current year presentation. These changes in presentation do not affect previously reported results. The Company has financed operations to date primarily through equity financing arrangements and has incurred operating losses and negative cash flows since its inception. As of December 31, 2023, the Company had a total cash, cash equivalents, and restricted cash balance of $34.8 million; an investments balance of $117.6 million, which was classified as available-for-sale; and an accumulated deficit of $661.6 million. During the year ended December 31, 2023, net loss incurred was $127.2 million and net cash used in operations was $79.0 million. The Company expects to continue to incur operating losses and negative cash flows from operations to support the development and marketing of its products, for the expansion of its product portfolio, and to continue its research and development activities. The Company’s activities are subject to significant risks and uncertainties, including market acceptance of the Company’s products, as well as the timing and extent of spending on research and development. The Company’s management plans to monitor expenses and raise additional capital through a combination of an initial public offering of shares of common stock, and potentially, strategic alliances. In May 2024, the Company received commitments from certain investors to provide additional capital of $380.0 million through the purchase of shares of the Company’s Series F-1 redeemable convertible preferred stock, subject to regulatory approval and satisfaction of customary closing conditions. Refer to Note 16 for further details. The Company’s ability to access capital when needed is not assured and, if capital is not available on acceptable terms to the Company when, and in the amounts, needed, the Company could be required to delay, scale back or abandon some or all of its development programs and other operations, which could materially harm the Company’s business, financial condition, and results of operations. If the Company is unable to obtain further funding, the Company may be forced to delay, reduce, or eliminate some or all of its research and development programs, product portfolio expansion, or commercialization efforts, which could adversely affect its business prospects. Management believes that the Company’s current cash and cash equivalents and investments are adequate to meet its needs for the next 12 months from the issuance of these consolidated financial statements. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. 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 consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. F-9


CEREBRAS SYSTEMS INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Areas of significant estimates include, but are not limited to, revenue recognition, including the determination of the standalone selling price (“SSP”) of performance obligations, useful life of property, plant and equipment, product warranty accruals, impairment of long-lived assets, the market value of and demand for inventory, valuation allowance on deferred income tax assets, the fair value of common stock and other assumptions used to measure stock-based compensation, and warrant liability. The Company bases its estimates on historical experience, known trends, and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. On an ongoing basis, management evaluates its estimates when there are changes in circumstances, facts, and experience. Changes in estimates are recorded prospectively in the period in which they become known. Actual results could significantly differ from those estimates.

Note 3 – Recent Accounting Pronouncements Not Yet Adopted In August 2020, the FASB issued ASU No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”), which simplifies an issuer’s accounting for convertible instruments by reducing the number of accounting models that require separate accounting for embedded conversion features. ASU 2020-06 also simplifies the settlement assessment that entities are required to perform to determine whether a contract qualifies for equity classification and makes targeted improvements to the disclosures for convertible instruments and earnings-per-share (EPS) guidance. This update will be effective for the Company’s fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Entities can elect to adopt the new guidance through either a modified retrospective method of transition or a fully retrospective method of transition. The Company does not expect this ASU to have a material impact on its consolidated financial statements. In June 2022, the FASB issued ASU No. 2022-03 Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions (“ASU 2022-03”), which clarifies that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value; clarifies that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction and requires the additional disclosures for equity securities subject to contractual sale restrictions. ASU 2022-03 is effective for the Company’s fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Early adoption is permitted for both interim and annual financial statements that have not yet been issued or made available for issuance. The Company does not expect this ASU to have a material impact on its consolidated financial statements. In November 2023, the FASB issued ASU No. 2023-07 Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”), which enhances the disclosures required for operating segments in the Company’s annual and interim consolidated financial statements. The disclosures required under ASU 2023-07 are also required for public entities with a single reportable segment. The ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of this ASU on its consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. The ASU is effective for public business entities for annual periods beginning after December 15, 2024. For all other entities, the standard is effective for annual periods beginning after December 15, 2025. Early adoption is permitted. The Company is currently evaluating the impact of this ASU on its consolidated financial statements. F-10


CEREBRAS SYSTEMS INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Note 4 – Significant Accounting Policies Risks and Uncertainties Credit Risk Financial instruments that potentially subject the Company to a concentration of credit risk consist primarily of cash, cash equivalents, investments, and accounts receivable. Investments are made with the primary objective of preservation of capital and maintenance of liquidity. The Company believes that the quality of financial instruments minimizes the exposure to concentration of credit risk. The Company holds cash, cash equivalents, and restricted cash at several major financial institutions, which may exceed insurance limits set by the Federal Deposit Insurance Corporation (“FDIC”). The Company has not historically experienced any losses due to such concentration of credit risk. The Company has no significant off-balance sheet risk, such as foreign exchange contracts, options contracts, or other hedging arrangements. The Company believes its credit policies are prudent and reflect normal industry terms and business risk. The Company’s exposure to credit risk for accounts receivable is indicated by the carrying value of its accounts receivable. The Company does not require customers to provide collateral to support accounts receivable. If deemed necessary, credit reviews of significant customers may be performed prior to extending credit. The determination of a customer’s ability to pay requires judgment, and failure to collect from a customer can adversely affect revenue, cash, and net earnings. Expected credit losses for uncollectible receivable balances consider both current conditions and reasonable and supportable forecasts of future conditions. Current conditions considered include predefined aging criteria, as well as specified events that indicate the balance due is not collectible. Reasonable and supportable forecasts used in determining the probability of future collections consider publicly available macroeconomic data and whether future credit losses are expected to differ from historical losses. The Company currently does not have an allowance for credit losses and expects to collect the full balance of accounts receivable. Significant Customers Revenue from significant customers, meaning those representing 10% or more of total revenue, was composed of one customer accounting for 83% of the Company’s revenue for the year ended December 31, 2023. Three customers accounted for 17%, 15%, and 13%, respectively, of the Company’s revenue for the year ended December 31, 2022. Accounts receivable from significant customers, those representing 10% or more of the total accounts receivable, was composed of four customers accounting for 43%, 22%, 15%, and 15%, respectively, of the Company’s accounts receivable balance as of December 31, 2023. Two customers accounted for 64%, and 35%, respectively, of the Company’s accounts receivable balance as of December 31, 2022. Supplier Risk Certain materials used by the Company in the manufacturing of its products are available from a limited number of suppliers. Shortages could occur in these materials due to an interruption of supply or increased demand in the industry. Three suppliers accounted for 21%, 19%, and 15% of total purchases for the year ended December 31, 2023. Two suppliers accounted for 25% and 11% of total purchases for the year ended December 31, 2022. Other Risks and Uncertainties The Company is subject to certain other risks and uncertainties, including, but not limited to, changes in any of the following areas that the Company believes could have a material adverse effect on its future financial position or results of operations: the Company’s ability to advance the development its products; market acceptance of its products; performance of third-party data center vendors; competition from other companies with greater financial resources or expertise; protection of intellectual property; litigation or claims brought by or made against the Company relating to intellectual property or other factors; and its ability to attract and retain employees necessary to support its growth. F-11


CEREBRAS SYSTEMS INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

The Company’s business and operations may be affected by worldwide economic conditions, which may continue to be impacted by global macroeconomic challenges, such as the effects of the ongoing conflict between Russia and Ukraine and between Israel and Palestine, tensions between the United States and China, uncertainty in the financial markets, including disruptions in the banking industry and inflationary trends. Revenue Recognition The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers, which provides a five-step framework through which revenue is recognized when control of promised goods or services is transferred to a customer at an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. To determine revenue recognition for arrangements that the Company concludes are within the scope of ASC 606, management performs the following five steps: (i) identifies the contract(s) with a customer; (ii) identifies the performance obligations in the contract(s); (iii) determines the transaction price, including whether there are any constraints on variable consideration; (iv) allocates the transaction price to the performance obligations; and (v) recognizes revenue when (or as) the Company satisfies a performance obligation. Revenue is recognized when control of the promised goods or services, through performance obligations by the Company, is transferred to the customer in an amount that reflects the consideration it expects to be entitled to in exchange for the performance obligations. The Company combines and accounts for multiple contracts as a single contract when they are negotiated together with the same customer at or near the same time in order to achieve a single commercial objective, or when the contracts are related in other ways. Transaction price may be comprised of fixed consideration, variable consideration, significant financing component, non-cash consideration, and consideration payable to a customer. The Company’s contracts are typically for fixed consideration. For all contracts with customers that have more than one performance obligation, the Company allocates the transaction price to each separate performance obligation based on the relative SSP of each performance obligation. The SSP is typically the price at which the Company sells a promised good or service separately to a customer. The best evidence of an SSP, if available, is the observable price charged in similar circumstances and to similar customers. If an SSP is not directly observable, the Company estimates SSP using various observable inputs including historical internal pricing data and cost-plus expected margin analysis due to the limited standalone sales history. The Company generates revenue primarily from the sale of AI Systems, support services, cloud-based computing services and custom AI modeling services. Hardware Sales Revenue and Installation, Integration, and Acceptance Testing Hardware revenue primarily consists of sales of the Company’s AI systems and other equipment. Revenue from the sale of AI systems is recognized upon transfer of control of promised goods to customers at a point in time. Revenue is recognized in an amount that reflects the consideration the Company expects to receive in exchange for those goods, net of allowances for returns, customer programs, and any taxes collected from customers. Generally, control of the goods transfers to the customer upon shipment, or delivery, depending on shipping terms, in the absence of installation, integration, and acceptance testing requirements. In certain cases, the Company may be contracted to install the hardware at the customer’s facility, and subsequent to installation, the Company may provide further integration services and conduct acceptance testing. When installation, integration, and acceptance testing is bundled with the hardware, control of the goods is transferred upon meeting the contractual acceptance provisions. Transaction price allocated to installation and integration services is recognized at a point in time upon completion of services, which generally coincides with the timing of customer acceptance and recognition of F-12


CEREBRAS SYSTEMS INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

revenue for the AI system. Revenue for installation and integration services is included in Services and other on the consolidated statement of operations. Other Equipment Customers regularly contract with the Company to purchase other equipment as needed, such as racks, coolant distribution units, and power supply units. In arrangements where another party is involved in providing specified goods or services to a customer, the Company evaluates whether it is the principal or agent. In this evaluation, the Company considers if control of the specified goods or services is obtained before they are transferred to the customer, as well as other indicators such as the party primarily responsible for fulfillment, inventory risk, and discretion in establishing price. For revenue arrangements where the Company is not the principal, revenue is recognized on a net basis. For the periods presented, revenue for arrangements where the Company was determined to be the agent was not material. Revenue recognized from sales of additional equipment follows similar revenue recognition patterns as hardware sales. Support Services The Company sells support services—including software updates, and customer care support—in one-year, two-year, or three-year terms. The support services represent an obligation of the Company to stand-ready to provide an undefined quantity of support over the duration of the service term. Under the provisions of the arrangement, customers may make requests of the Company to deliver some or all of the customer support services at some point during the period defined in the contract, or the delivery of some or all of the services on a when-and-if-available basis may be in the control of the entity (i.e., software updates). The customer benefits from the Company’s stand-ready obligation evenly throughout the contract period, and as a result, revenue is recognized ratably over the service term. Cloud-based Computing Services The Company also provides cloud-based computing services to customers. In each case, the totality of services provided represents a single integrated solution tailored to the customer’s specific needs. As such, the performance obligations to the customers consists of a single integrated solution delivered as a series of distinct daily services. The customers benefit from the services over the contract term and as such revenue is recognized over time as services are provided. AI Modeling Services The Company also generates revenue from custom AI modeling service agreements with customers, whereby the Company is engaged to help customers throughout the AI workflow, starting with developing strategy, designing and building the model, and deploying the final model. The totality of services in such arrangements are broken into different milestones within the contract. In certain contracts, each milestone builds upon progress achieved in earlier milestones. Upon completion of each milestone, the Company provides a deliverable to the customer in certain contracts, which must be accepted by the customer in order to proceed with the next phase of the contract. Each milestone is typically for fixed consideration. If an SSP is not directly observable, the Company estimates SSP using various observable inputs including cost-plus expected margin analysis due to the limited standalone sales history. The Company recognizes revenue from AI modeling services over time as services are provided or at a point in time upon completion and acceptance by the customer of contract deliverables, depending on the terms of the agreement. The Company generally warrants its products to be free of defects generally for a period of one to two years. This assurance-type warranty is not considered a separate performance obligation, and thus, no transaction price is allocated to it. The Company estimates its warranty costs based on historical warranty claim experience and includes such costs in the cost of sales. F-13


CEREBRAS SYSTEMS INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

Contract Assets and Liabilities The payment terms and conditions in the Company’s customer contracts vary. In some cases, customers prepay for their goods and services; in other cases, after appropriate credit evaluations, payment is due in arrears, typically no longer than one year. When the timing of the Company’s delivery of hardware and provision of services is different from the timing of the payments made by customers, the Company recognizes either a contract asset or a contract liability. Contract assets represent deferred cost of sales related to revenue that has not yet been recognized, and unbilled receivables related to revenue that has been recognized but not yet invoiced. The balance of contract assets was $0.2 million, $0.5 million and $0.5 million as of December 31, 2023, December 31, 2022 and December 31, 2021, respectively, in prepaid expenses and other current assets. Contract liabilities are recorded in deferred revenue and represent amounts that have been invoiced, or received in advance, but have not yet been recognized as revenue. Revenue allocated to remaining performance obligations that is unsatisfied (or partially unsatisfied) includes amounts received from customers and amounts that will be invoiced and recognized as revenue in future periods, was $19.2 million as of December 31, 2023. The Company expects to recognize approximately 71% of this revenue over the next 12 months and the remainder thereafter. Cash, Cash Equivalents, and Restricted Cash Cash and cash equivalents include cash on hand and highly liquid investments with an original maturity of three months or less. The Company’s cash and cash equivalents are invested in various investment grade institutional money market funds and bank money market and interest-bearing accounts. Restricted cash includes cash and cash equivalents that are not readily available for use in the Company’s operating activities. Restricted cash is attributable to minimum cash reserve requirements under the Company’s letter of credit issued in connection with one of the Company’s real estate leases. Investments Investments consist primarily of time deposits, U.S. Treasury securities, and corporate debt securities that have an initial maturity of greater than three months but less than or equal to one year at period-end. The Company classifies its investments in debt securities as available for sale. These available-for-sale debt securities are reported at fair value. The fair value of interest-bearing debt securities includes accrued interest. Debt securities are carried at fair value, with the unrealized gains and losses reported as a component of accumulated other comprehensive loss, except for the changes in allowance for expected credit losses, which are recorded in other income, net. The Company determines any realized gains or losses on the sale of, or maturity of, debt securities on a specific identification method, and the Company records such realized gains and losses in other income, net. All of the Company’s available-for-sale debt investments are subject to a periodic impairment review. For available-for-sale debt securities in an unrealized loss position, the Company determines whether a credit loss exists. The credit loss is estimated by considering available information relevant to the collectability of the security and information about past events, current conditions, and reasonable and supportable forecasts. Any credit loss is recorded as a charge to other income, net, not to exceed the amount of the unrealized loss. Unrealized losses other than the credit loss are recognized in accumulated other comprehensive income (loss). If the Company has an intent to sell, or if it is more likely than not that the Company will be required to sell a debt security in an unrealized loss position before recovery of its amortized cost basis, it will write down the security to its fair value and record the corresponding charge as a component of other income, net. There were no credit losses or impairment charges for the years ended December 31, 2023 and 2022. F-14

Fair Value of Financial Instruments The Company determines fair value measurements used in its consolidated financial statements based upon the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy distinguishes between (i) market participant assumptions developed based on market data obtained from independent sources (observable inputs), and (ii) an entity’s own assumptions about market participant assumptions developed based on the best information available in the circumstances (unobservable inputs). The fair value hierarchy consists of three broad levels, which gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy are described below: •Level 1 inputs are quoted prices in active markets for identical assets and liabilities; •Level 2 inputs, other than quoted prices included within Level 1, are observable for the asset or liability either directly or indirectly; and •Level 3 inputs are not observable in the market. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The carrying amounts of the Company’s financial instruments consisting of cash and cash equivalents, accounts receivable, accounts payable, and accrued liabilities approximate fair value due to their relatively short maturities. The fair value of investments is estimated using Level 2 inputs (Note 8). The fair value of warrant liabilities is estimated using Level 3 inputs (Note 11). Accounts Receivable The Company has trade receivables which are recorded at the invoiced amount and do not bear interest. The Company evaluates the collectability of accounts receivable on a regular basis based on economic assessment of market conditions and review of customer financial history. There was no allowance for credit losses recorded as of December 31, 2023 and 2022. Inventory Inventories consist of raw materials, work-in-progress and finished goods and are stated at the lower of cost or net realizable value. Costs are measured on a weighted average cost basis. Net realizable value is the estimated selling price of the Company’s products in the ordinary course of business less reasonably predictable costs of completion, disposal, and transportation. Inventories are written down to their net realizable value if they have become obsolete, have a cost basis in excess of expected net realizable value, or are in excess of expected demand. Once inventory is written down, its new value is maintained until it is sold, scrapped, or written down for further valuation losses. The valuation of inventories requires the Company to make judgments based on currently available information about the likely method of disposition and current and future product demand relative to the remaining product life. Process and product development lifecycle corresponds with substantive engineering milestones. These engineering milestones are regularly and consistently applied in assessing the point at which activities and associated costs change in nature from research and development to cost of sales and when cost of sales can be capitalized as inventory. Inventory costs consist primarily of the cost of semiconductors, memory products, and other component parts purchased from subcontractors, including wafer fabrication, assembly, testing, and manufacturing support costs, including labor and overhead associated with such purchases, final test yield fallout, and shipping costs. Inventory is valued at the lower of cost or net realizable value, based upon assumptions about future demand and market conditions. F-15


CEREBRAS SYSTEMS INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

The valuation of inventory also requires the Company to estimate obsolete and excess inventory, as well as inventory that is not salable quality. Cost of sales is charged for inventory provisions to write down inventory to the lower of cost or net realizable value or to completely write off excess or obsolete inventory. Most inventory provisions relate to write-downs for inventory that is not salable quality. Property and Equipment, Net Property and equipment are recorded at cost, less accumulated depreciation. Expenditures for major additions and improvements to property and equipment are capitalized and repairs and maintenance costs are expensed as incurred. When assets are retired or disposed of, the cost and accumulated depreciation are removed from the respective accounts and any related gain or loss is recognized. Property and equipment are depreciated using the straight-line method over the estimated useful lives of the property and equipment as follows:

Asset Category

Asset Category / Asset Category / Useful Life (Years) / Useful Life (Years) / Useful Life (Years)

Computer equipment ...................... Computer equipment / Computer equipment / 1.5 – 3 / 1.5 – 3 / 1.5 – 3

Furniture and fixtures .................. Furniture and fixtures / Furniture and fixtures / 3 / 3 / 3

Software ................................ Software / Software / 3 / 3 / 3

Machinery and equipment ................. Machinery and equipment / Machinery and equipment / 7 / 7 / 7

Leasehold improvements .................. Leasehold improvements / Leasehold improvements / Lesser of estimated useful life or remaining lease term / Lesser of estimated useful life or remaining lease term / Lesser of estimated useful life or remaining lease term

Estimated useful lives are periodically assessed to determine if changes are appropriate. When assets are retired or otherwise disposed of, the cost of these assets and related accumulated depreciation or amortization are removed from the accounts and any resulting gains or losses are included in loss from operations in the period of disposal. Leases Lessee Accounting The Company determines if an arrangement is a lease at its inception. Operating leases with lease terms of more than 12 months are included in right-of-use assets and operating lease liabilities in the consolidated balance sheets. Right-of-use assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease liabilities and right-of-use assets are recognized at commencement date based on the present value of lease payments over the lease term. The Company uses its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments if an explicit rate is not available. The right-of-use assets also includes any rent prepayments, lease incentives upon receipt, and straight-line rent expense impacts, which represent the differences between operating lease liabilities and right-of-use assets. Lease terms include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease and non-lease components have been combined. Lessor Accounting Leases not classified as sales-type or direct financing leases are classified as operating leases. If a lease that meets the criteria to be classified as either a sales-type or direct financing lease, and the application of such classification would result in the recognition of a selling loss, then the Company classifies such leases as an operating lease. The primary accounting criteria used to determine if the leases are sales-type or direct financing leases are: (i) review to determine if the lease transfers ownership of the underlying asset to the lessee by the end of the lease term, (ii) review to determine if the lease grants the lessee a purchase option that the lessee is reasonably certain to exercise, (iii) determine if the lease term is for a major part of the remaining economic life of the F-16


CEREBRAS SYSTEMS INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

underlying asset (iv) determine if the present value of the sum of the lease payments and any residual value guarantees equals or exceeds substantially all of the fair value of the underlying asset, (v) determine if the leased asset is of such a specialized nature that it is expected to have no alternative use to the Company at the end of the lease term, (vi) determine if the present value of the sum of the lease payments and any residual value guarantees by the lessee and/or any other third party unrelated to the lessor equals or exceeds substantially all of the fair value of the underlying asset, and (vii) determine if it is probable that the Company will collect the lease payments, plus any amount necessary to satisfy residual value guarantee. If none of the above criteria are met, the lease is classified as operating. The Company currently has only one lease as a lessor, which was initially classified as an operating lease and was subsequently classified as sales-type upon modification of the agreement with the customer. The Company recognized revenue associated with the sales-type lease upon delivery and acceptance by the customer. Assets leased under an operating lease are carried at cost, less accumulated depreciation. These assets are depreciated to their estimated residual value using the straight-line method over the lesser of the lease term or estimated useful life of the asset. The Company recognizes operating lease revenue on a straight-line basis over the lease term. Impairment of equipment under operating leases is assessed on the same basis as other long-lived assets. Impairment of Long-Lived Assets The Company assesses the recoverability of its long-lived assets, including property and equipment and right-of-use assets, for indicators of impairment. If events or changes in circumstances indicate impairment, the Company measures recoverability by a comparison of the asset’s carrying amount to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of the asset exceeds its estimated future cash flows, an impairment charge is recognized for the amount by which the carrying amount of the asset exceeds the fair value of the asset. When quoted market prices are not available, the Company uses the expected future cash flows discounted at a rate commensurate with the risks associated with the recovery of the asset as an estimate of fair value. No impairment of long-lived assets was identified for the years ended December 31, 2023 and 2022. Provision for Product Warranties The Company offers product warranties ranging from one to two years against any defective products. These standard warranties are assurance-type warranties, and the Company does not offer any services beyond the assurance that the product will continue working as specified. Therefore, these warranties are not considered separate performance obligations in the arrangement. Based on historical experience, the Company accrues for estimated returns of defective products at the time revenue is recognized. The Company monitors warranty obligations and may make revisions to its warranty reserve if actual costs of product repair and replacement are significantly higher or lower than estimated. Accruals for anticipated future warranty costs are charged to cost of sales. Warranty accruals are based on estimates that are updated on an ongoing basis taking into consideration inputs such as new product introductions, changes in the volume of claims compared with the Company's historical experience, and the changes in the cost of servicing warranty claims. The Company accounts for the effect of such changes in estimates prospectively. The following table shows the changes in provision for product warranty during the year ended December 31, 2023 and 2022 (in thousands):

Research and Development Costs Research and development costs are expensed in the period incurred. Research and development expenses primarily consist of costs incurred in performing research and development activities and include salaries, stock-based compensation, employee benefits, tape-out costs, which include layout services, mask sets, prototype components, system qualification and testing incurred before releasing new system designs into production, data center costs, depreciation and amortization, professional services fees, cloud computing costs and facilities expenses. The Company expenses software development costs, including costs to develop the software component of hardware to be sold, leased, or marketed to external users, before technological feasibility is reached. Technological feasibility is typically reached shortly before the release of such products and as a result, development costs that meet the criteria for capitalization were not material for the periods presented. Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets (“DTAs”) and deferred tax liabilities (“DTLs”) for the expected future tax consequences of events that have been included in the consolidated financial statements. Under this method, DTAs and DTLs are determined on the basis of the differences between the financial statement and tax bases of assets and liabilities by using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on DTAs and DTLs is recognized in income in the period that includes the enactment date. The Company recognizes DTAs to the extent that these assets are more likely than not to be realized. In making such a determination, all available positive and negative evidence are considered, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. If it is determined that the DTAs in the future in excess of their net recorded amount can be realized, an adjustment to the DTA valuation allowance will be made, which would reduce the provision for income taxes. Due to the Company's historical operating performance and net losses, the net deferred tax assets have been fully offset by a valuation allowance. The Company records uncertain tax positions on the basis of a two-step process in which (1) determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority is realized. Changes in recognition or measurement are reflected in the period in which the judgment occurs. The Company's policy is to recognize interest and penalties related to the underpayment of income taxes as a component of the provision for income taxes. Stock-Based Compensation The Company’s 2016 Equity Incentive Plan (as amended, the “Equity Incentive Plan”) provides for the Company to grant incentive stock options (“ISOs”), non-statutory stock options (“NSOs”), restricted stock units (“RSUs”), and restricted stock awards (“RSAs”) to employees, advisers, and directors. The Company measures stock-based compensation awards exchanged for employee services at fair value on the date of the grant and recognizes expense on a straight-line basis over the award’s vesting period. The requisite service period generally equals the vesting period of the awards. The Company estimates the grant date fair value using the Black-Scholes option-pricing model. The fair value of RSUs and RSAs are based on the Company’s stock price on the date of grant. The Company estimates forfeitures at the date of grant, based on historical experience, and revises, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company’s estimates may be impacted by certain variables, including, but not limited to, stock price volatility, employee retirement eligibility dates, the Company’s performance, and related tax impacts. For certain equity awards that have both service and performance conditions, the Company recognizes the expense over the requisite service period if it is probable that F-18


CEREBRAS SYSTEMS INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

the performance conditions will be achieved. The Company reassesses the achievement of the performance conditions at each reporting date and adjusts the stock-based compensation accordingly. Treasury Stock The Company records repurchases of common shares as treasury stock at cost and records subsequent retirements of treasury shares at cost. The amount of cash or other assets transferred to repurchase an equity award is charged to equity to the extent that the amount paid does not exceed the fair value of the equity instrument being repurchased at the repurchase date. Any amount paid in excess of fair value is attributed to the other elements of the transaction and accounted for according to their substance. When treasury shares are retired, the excess of the repurchase price over the par value of the shares acquired is allocated to both retained earnings and additional paid-in capital. The portion allocated to additional paid-in capital is calculated on a pro rata basis of the shares to be retired and the total shares issued and outstanding as of the date of retirement. Foreign Currency Translation and Transaction Gains and Losses The functional currencies of the Company’s wholly owned subsidiaries in India, Canada and Japan are the Indian Rupee, Canadian Dollar, and Yen, respectively. Accordingly, asset and liability accounts of these subsidiaries are translated into U.S. dollars using the current exchange rate in effect at the balance sheet date and equity accounts are translated into U.S. dollars using historical rates. The revenues and expenses are translated using the average exchange rates in effect during the period, and gains and losses from foreign currency translation adjustments are included as a component of accumulated other comprehensive income in the consolidated balance sheet. Foreign currency translation adjustments are recorded in other comprehensive income (loss) in the consolidated statements of operations and comprehensive loss and were $0.1 million and $0.3 million during the years ended December 31, 2023 and 2022, respectively. Foreign currency transaction gains and losses are included in other income (expense), net in the consolidated statements of operations and comprehensive loss and were not material during the years ended December 31, 2023 and 2022. Comprehensive Loss The Company is required to report all components of comprehensive loss, including net loss, in the financial statements in the period in which they are recognized. Comprehensive gain or loss is defined as a change in equity of a business enterprise during a period, resulting from transactions and other events and circumstances from non-owner sources. The Company’s currency translation adjustment and unrealized gains and losses from marketable securities are the components of other comprehensive income (loss) that are excluded from the reported net loss for all periods presented.

Note 6 – Segment and Geographical Information The Company operates as one operating segment. Operating segments are defined as components of an enterprise for which separate financial information is regularly evaluated by the chief operating decision maker (“CODM”), which is the Company’s Chief Executive Officer, in deciding how to allocate resources and assess performance. The Company’s CODM evaluates the Company’s financial information and resources and assesses the performance of these resources on a consolidated basis. The Company is not organized by market and is managed and operated as one business. Accordingly, the Company does not accumulate discrete financial information with respect to separate divisions and does not have separate operating or reportable segments. Since the Company operates as one operating segment, all required financial segment information can be found in the consolidated financial statements. F-20

CEREBRAS SYSTEMS INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

The holders of redeemable convertible preferred stock have various rights and preferences, including the following: Conversion The redeemable convertible preferred stock is convertible, at any time and from time to time at the option of its holder, into fully paid and non-assessable shares of common stock at a 1:1 ratio, subject to certain adjustments for splits, dividends, other similar recapitalization, and the like. Conversion of all classes of redeemable convertible preferred stock to shares of common stock is automatic in the event of a qualified initial public offering with a public offering price of at least $100 million in the aggregate. Voting The holders of the redeemable convertible preferred stock are entitled to vote, together with the holders of shares of common stock, as a single class, on all matters submitted to the stockholders for a vote and are entitled to the number of votes equal to the number of shares of common stock into which the shares of redeemable convertible preferred stock could convert on the record date for determination of stockholders entitled to vote. Dividends The holders of the redeemable convertible preferred stock are entitled to receive noncumulative dividends, as and if declared by the board of directors. The Company may not pay any dividends on shares of common stock of the Company unless the holders of shares of redeemable convertible preferred stock then outstanding first receive, or simultaneously receive, a dividend on each outstanding share of redeemable convertible preferred stock in an amount equal to 8% of the original issue price per share of such redeemable convertible preferred stock. Liquidation Preference In the event of any voluntary or involuntary liquidation, dissolution, or winding-up of the Company or deemed liquidation events, the holders of shares of redeemable convertible preferred stock then outstanding are entitled to be paid out of the funds and assets available for distribution to the Company’s stockholders an amount per share equal to the greater of (a) the original issue price for such series of redeemable convertible preferred stock, plus any dividends declared but unpaid, or (b) such amount per share as would have been payable had all shares of such series of redeemable convertible preferred stock been converted into shares of common stock immediately prior to such liquidation, dissolution, winding-up, or deemed liquidation event. Redemption In addition, holders of the redeemable convertible preferred stock are eligible to demand redemption of their shares in the event of certain deemed liquidation events, as defined in the restated certificate of incorporation. Due to the various rights and privileges within the existing redeemable convertible preferred stock and common stockholder agreements, the Company concluded the triggering of a deemed liquidation event is not solely within the control of the Company and, accordingly, has presented the redeemable convertible preferred stock as temporary equity. As of December 31, 2023, the Company determined that a deemed liquidation event is not probable because there are currently no plans for a change of control, merger or consolidation, or sale of substantially all assets. Therefore, subsequent remeasurement of redeemable convertible preferred stock presented in temporary equity is not required. As of each reporting date and on an ongoing basis, the Company will continue to assess the probability of redemption.

Note 11 – Common Stock As of December 31, 2023 and 2022, the Company was authorized to issue 168,000,000 shares and 158,000,000 shares of $0.00001 par value common stock, respectively. As of December 31, 2023 and 2022, the Company had F-25


CEREBRAS SYSTEMS INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

45,361,795 and 43,011,356 shares of common stock legally issued and outstanding, respectively, of which 95,905 and 400,145, respectively, shares of common stock were subject to repurchase as of such date for early exercised stock options. As of December 31, 2023 and 2022, the Company had 300,138 shares of common stock held as treasury shares, which may be used for issuance under the Equity Incentive Plan. All shares that were issued upon early exercise of stock options are considered legally issued and outstanding. However, for accounting purposes, only shares that are fully vested or are not subject to repurchase are considered issued and outstanding.

The voting, dividend, and liquidation rights of the holders of the Company’s shares of common stock are subject to and qualified by the rights, powers, and preferences of the holders of shares of the Company’s redeemable convertible preferred stock. Each share of common stock entitles the holder to one vote on all matters submitted to a vote of the Company’s stockholders. Common stockholders are entitled to receive dividends, if any, as may be declared by the board of directors, subject to the preferential dividend rights of the preferred shares. Through December 31, 2023, no cash dividends had been declared or paid by the Company. In August 2022, the Company issued 599,880 shares of common stock for gross proceeds of $10.0 million to a certain stockholder pursuant to a stock purchase agreement. Additionally, the board of directors authorized the repurchase of shares of the Company’s common stock from certain founders and employees in August 2022. For the year ended December 31, 2022, the Company repurchased an aggregate of 599,880 shares for an aggregate purchase price of $10.0 million. The repurchased shares were immediately retired. All of the shares were repurchased above fair value, and as such, the amount paid in excess of fair value has been attributed to other elements of the transaction and accounted for according to their substance. In this case, the excess of $6.2 million was recognized in compensation expense as the repurchased shares of common stock had initially been issued as compensatory shares. Also, in connection with this transaction, the Company allocated $0.8 million to additional paid-in capital and $3.0 million to accumulated deficit. There were no shares repurchased during and for the year ended December 31, 2023. Warrants In August 2020, the Company entered into an equity arrangement with one of its customers whereby the Company issued a warrant that is exercisable for up to 68,213 shares of its Series E redeemable convertible preferred stock. The warrant is classified as a liability and remeasured to fair value and fall under Level 3 of the fair value hierarchy. As of December 31, 2023 and 2022, the warrant was valued at $1.1 million and $1.1 million, respectively. The Company provided services and issued the warrant to the customer, and the customer paid the consideration to the Company for the provision of services. The warrant has a contractual term of seven years and an exercise price of $0.00001 per share. The customer is able to either exercise the warrants at the exercise price or convert a portion of the warrants into a number of shares of Series E redeemable convertible preferred stock adjusted to equal the fair market value, less the exercise price. The fair value of warrants is determined using a Black-Scholes option-pricing model as of the grant date. The amount representing the fair value of the equity provided to the customer from the warrant is recognized as adjustments of revenue in the consolidated statements of operations and comprehensive loss over the term of such commercial agreement or based on the achievement of certain performance targets in accordance with ASC 505-50.

For the years ended December 31, 2023 and 2022, a decrease in fair value of $28 thousand and an increase in $0.5 million related to the warrant was recognized in other income, net, respectively.

Note 12 – Stock-Based Compensation The Equity Incentive Plan provides for the Company to grant ISOs, NSOs, RSUs, and RSAs to employees, advisers, and directors. As of December 31, 2023 and 2022, there were 51,711,838 and 45,711,838 equity awards authorized, respectively. Stock Options Stock options represent the right to purchase shares of common stock on the date of exercise at a stated exercise price. The exercise price of a stock option generally must be at least equal to the fair market value of the common stock on the date of grant. Options vest over periods of two years or more and are exercisable over a period of time not to exceed 10 years from the grant date. For the years ended December 31, 2023 and 2022, the Company recorded aggregate stock-based compensation expense of $26.6 million and $23.0 million, respectively. Approximately $1.0 million and $1.4 million of the compensation expense recognized for the years ended December 31, 2023 and 2022, respectively, was attributed to certain share-based awards, which provided the employee the option to choose between equity or cash, of which approximately $0.4 million and $0.7 million was included in accrued compensation on the consolidated balance sheets as of December 31, 2023 and 2022, respectively. Approximately $9.0 million and $2.4 million of the compensation expense recognized for the years ended December 31, 2023 and 2022, respectively, was attributed to sales of shares of common stock by certain current and former employees of the Company to certain economic interest holders in the Company, through secondary market transactions, where the excess price paid above fair value for shares was recorded as stock-based compensation expense. Approximately $0 and $6.2 million of the compensation expense recognized for the years ended December 31, 2023 and 2022, respectively, was attributable to the allocation of the excess price paid above fair value of shares for F-27


CEREBRAS SYSTEMS INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

shares repurchased from employees during the year by the Company. Stock-based compensation expense is reflected in research and development, general and administrative, sales and marketing, and cost of sales on the consolidated statements of operations. The terms of the plan permit certain option holders to exercise options before their options are vested, subject to certain limitations. Upon early exercise, the awards become subject to a restricted stock agreement. The shares of restricted stock granted upon early exercise of the options are subject to the same vesting provisions in the original stock option awards. Shares issued as a result of early exercise that have not been vested are subject to repurchase by the Company upon termination of the purchaser’s employment, at the price paid by the purchaser. Such shares are not deemed to be issued for accounting purposes until they vest. The liability is reclassified into common stock and additional paid-in capital as the shares vest and the repurchase right lapses. As of December 31, 2023 and 2022, 95,905 and 400,145 unvested shares, respectively, were held by employees. Accordingly, the Company recorded the unvested portion of the exercise proceeds of $0.2 million and $1.0 million as a liability from the early exercise in the accompanying consolidated balance sheets as of December 31, 2023 and 2022, respectively. The following table summarizes the Company’s stock option activity and related information:

The aggregate intrinsic value of options is calculated as the difference between the exercise price of the stock options and the fair value of the Company’s shares of common stock for those options that had exercise prices lower than the fair value of the Company’s shares of common stock. The total intrinsic value for stock options exercised during the years ended December 31, 2023 and 2022, was $6.7 million and $8.7 million, respectively. The total intrinsic value of stock options vested during the years ended December 31, 2023 and 2022 was $8.6 million and $20.5 million, respectively. The weighted-average grant date fair value of options granted was $3.05 and $4.18 per share for the years ended December 31, 2023 and 2022, respectively. As of December 31, 2023 and 2022, the total remaining unrecognized compensation expense related to non-vested stock options was $42.0 million and $32.9 million, respectively, which will be amortized over the weighted-average period of 2.50 years and 2.55 years, respectively. The fair value of each option award is determined on the date of grant using the Black-Scholes option-pricing model. The calculation of fair value includes several assumptions that require management’s judgment. The absence of a public market for the Company’s common stock requires the Company’s board of directors with assistance from management and external valuation experts, to estimate the fair value of its common stock for purposes of granting options and for determining stock-based compensation expense by using a reasonable method of valuation and considering several objective and subjective factors, including obtaining contemporaneous independent third-party valuations, actual and forecasted operating and financial results, market conditions and performance of comparable publicly traded companies, developments and milestones in the Company, the rights and preferences of redeemable convertible preferred stock and common stock, and transactions involving the Company’s stock. The fair value of F-28


CEREBRAS SYSTEMS INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

the Company’s common stock was determined in accordance with applicable elements of the American Institute of Certified Public Accountants guide, Valuation of Privately Held Company Equity Securities Issued as Compensation. The estimated fair value of stock options was determined using the Black-Scholes option-pricing model with the following weighted-average assumptions:

Expected dividend yield (%) ............. Expected dividend yield (%) / Expected dividend yield (%) / — / — / — / —

Expected term: The expected term of the stock options represents the period of time stock options are expected to be outstanding and is based on the “simplified method.” Under this method, the term is estimated using the midpoint between the requisite service period and the contractual term of the option. This method is used due to the lack of sufficient historical exercise data. Expected volatility: The expected volatility is a measure of the amount by which a financial variable, such as a share price has fluctuated (historical volatility) or is expected to fluctuate (expected volatility) during a period. As the Company does not yet have a sufficient history of its own volatility, the Company has identified several public entities of similar complexity and industry and calculates historical volatility based on the volatilities of these companies. Risk-free interest rate: The risk-free interest rate is based on U.S. Treasury yield curve in effect at the time of grant. Expected dividend yield: No dividends have been paid or expected to be paid by the Company.

RSUs and RSAs RSUs represent a right to receive one share of common stock for each RSU that vests. Unless otherwise determined by the Compensation Committee at the time of grant, vesting ceases on the date the participant no longer provides services to the Company and unvested shares are forfeited. If an RSU has not been forfeited, then on the date specified in the RSUs, the Company delivers to the holder a number of whole shares of common stock. Dividend equivalents, if any, are not credited in respect of shares covered by the RSUs, except as otherwise permitted by the Compensation Committee. As of December 31, 2023 and 2022, the Company had 1,516,408 and F-29


CEREBRAS SYSTEMS INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

725,000 non-vested RSUs, respectively. The Company has granted RSUs that vest on satisfaction of both service- and liquidity-based vesting conditions. An RSA is an offer by the Company to sell shares of common stock that are subject to certain specified restrictions determined by the Compensation Committee. Prior to vesting or forfeiture, a participant will have all rights of a stockholder with respect to the shares of common stock underlying the RSA, including the right to receive dividends and vote the underlying shares of common stock; provided, however, the participant may not transfer the shares. As of December 31, 2023 and 2022, the Company had no unvested RSAs. The following table summarizes RSU/RSA activity and related information:

The realization of deferred tax assets is dependent upon the generation of sufficient taxable income of the appropriate character in future periods. The Company regularly assesses the ability to realize its deferred tax assets and establishes a valuation allowance if it is more-likely-than-not that some portion of the deferred tax assets will not be realized. The Company weighs all available positive and negative evidence, including its earnings history and results of recent operations, scheduled reversals of deferred tax liabilities, projected future taxable income, and tax planning strategies. Due to the weight of objectively verifiable negative evidence, including its history of losses in the United States, the Company believes that it is more likely than not that its U.S. federal and state deferred tax assets will not be realized. Accordingly, the Company has recorded a valuation allowance on such deferred tax assets. The valuation allowance against the Company’s various deferred tax assets increased by $32.9 million and $47.9 million during the years ended December 31, 2023 and December 31, 2022, respectively. As of December 31, 2023, the Company had federal, state, and foreign net operating loss carryforwards in the amount of $333.8 million, $395.5 million, and $10 thousand, respectively, available to offset future taxable income. The federal net operating loss has an indefinite carryforward period but is limited to offset 80% of taxable income in the year utilized, except for $20.6 million that will begin to expire in 2036. The state net operating loss carryforwards have various carryover periods and will begin to expire as early as 2036. As of December 31, 2023, the Company had federal, California, and Canadian research and development credit carryforwards of $28.1 million, $22.6 million, and $2 million, respectively. The federal research and development credits will begin to expire in 2037, the California research and development credits have no expiration, and the Canadian research and development credits will begin to expire in 2041. Utilization of the Company’s net operating loss and credits may be subject to annual limitations due to the ownership change limitations provided by section 382 of the Internal Revenue Code (“Section 382”) and similar provisions. If ownership changes within the meaning of Section 382 have occurred, the amount of remaining tax attribute carryforwards available to offset future taxable income and income taxes in future years may be restricted. Further, the Company’s deferred tax assets, along with the corresponding valuation allowance, associated with such F-32


CEREBRAS SYSTEMS INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

tax attributes could be impacted upon an ownership change within the meaning of Section 382. Due to the existences of the valuation allowance, changes in the Company’s deferred tax assets from any such limitation will not impact the Company’s effective tax rate. The Company’s net operating loss carryforwards and credits could expire before utilization if subject to annual limitations.

All of the Company’s tax years remain open for examination by U.S. federal and state tax authorities. The non-U.S. tax returns remain open for examination for the years 2020 and onwards. Due to the Company’s federal and state valuation allowance, none of the unrecognized tax benefits as of December 31, 2023 and December 31, 2022, respectively, would affect the effective tax rate if recognized. As of December 31, 2023 and 2022, there were no accrued interest and penalties related to uncertain tax positions. The Company does not believe its unrecognized tax benefits will significantly change in the next 12 months. U.S. income tax has not been recognized on the excess of the amount for financial reporting over the tax basis of investments in foreign subsidiaries that is indefinitely reinvested outside the United States. As a result of the Tax Act, the tax impact of future distributions of foreign earnings would generally be limited to withholding tax from local jurisdictions. The amount of the deferred tax liability on the excess of the amount for financial reporting over the tax basis of investments in foreign subsidiaries was not material.

Note 14 – Leases As a Lessee The Company’s lease obligations consist of operating leases for facilities and offices. The extension periods have not been included in the determination of the right-of-use assets or the lease liability for operating leases as the Company did not consider it reasonably certain that it would exercise these options. The Company has elected not to recognize right-of-use assets and operating lease liabilities that arise from short-term (12 months or less) leases for any class of underlying assets. The Company has elected not to separate lease and non-lease components for any class of underlying asset. As of December 31, 2023, future minimum lease payments of the Company’s operating lease liabilities were due as follows (in thousands):

Note 15 – Commitments and Contingencies The Company has entered into certain contracts to receive consulting and other services that represent unconditional purchase obligations to purchase goods or services that are enforceable and legally binding. Purchase commitments exclude agreements that are cancellable without penalty and unconditional purchase commitments with a remaining term of one year or less. As of December 31, 2023, future payments related to non-cancelable commitments under these contracts are due as follows: $8.7 million (2024), $8.7 million (2025), and $1.5 million (2026). In the ordinary course of business, the Company may be subject from time to time to various proceedings, lawsuits, disputes, or claims. Although the Company cannot predict with assurance the outcome of any litigation, it does not believe there are currently any such actions that, if resolved unfavorable, would have a material impact on the Company’s financial condition, results of operations, or cash flows.

Note 16 – Subsequent Events The Company has evaluated all transactions through June 17, 2024, the date these consolidated financial statements were available to be issued and has determined that there are no other events, other than the following, that would require disclosure in or adjustment to these financial statements. Series F-1 Financing In May 2024, the Company entered into a Series F-1 redeemable convertible preferred stock purchase agreement (the “Series F-1 Purchase Agreement”) with various investors. Pursuant to the Series F-1 Purchase Agreement, an entity affiliated with Group 42 Holding Ltd (together with its affiliates, “G42”) agreed to purchase 22,851,296 shares of the Company’s Series F-1 redeemable convertible preferred stock, and an existing stockholder agreed to purchase 3,069,577 shares of the Company’s Series F-1 redeemable convertible preferred stock, in each case at a purchase price of $14.66 per share (the “Series F-1 Financing”). G42’s purchase of shares in the Series F-1 Financing is subject to regulatory approval, as well as the satisfaction of customary closing conditions. Pursuant to the Series F-1 Purchase Agreement, if G42 or certain third parties at the direction of G42 purchase more than $500.0 million in one purchase order, and less than $5.0 billion in the aggregate, of high-performance computing clusters from us (the “G42 Option Threshold”), the Company will grant G42 the option to purchase additional shares of Series F-1 redeemable convertible preferred stock (or, if such option is granted or exercised following the completion of the Company’s initial public offering, shares of the Company’s common stock), subject to the terms thereof (the “G42 Option”). The maximum number of shares that may be purchased pursuant to the G42 Option will be the quotient of (i) the total aggregate purchase price for the G42 Option, which will equal 10% of the value of the relevant purchaser order(s), divided by (ii) (A) if the G42 Option is granted and exercised prior to the completion of the Company’s initial public offering, a price per share that is 17.5% below the price per share of the Company’s then most recent arms-length sale of the Company’s redeemable convertible preferred stock (excluding F-35


CEREBRAS SYSTEMS INC. NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

the Company’s Series F-1 redeemable convertible preferred stock), or (B) if the G42 Option is granted or exercised following the completion of the Company’s initial public offering, a price per share that is 17.5% below the average closing price per share of the Company’s common stock over the 30-day period prior to the G42 Option Threshold being met. The G42 Option expires on December 31, 2025. G42’s ability to purchase shares in connection with the G42 Option is subject to regulatory approval. Customer Prepayment In April 2024, the Company and G42 entered into an agreement pursuant to which G42, or a third party nominee affiliated with G42, intends to issue purchase orders for the Company’s AI supercomputer products for a minimum value of $300 million. Pursuant to the terms of the agreement, the Company received a prepayment of $300 million from G42 in May 2024, which is restricted to be used only for payments to third-party vendors to manufacture high performance computing infrastructure. If the purchase orders are not issued by G42, any portion of the prepayment not paid by the Company to its third-party vendors will be payable to G42 on demand and the Company’s rights on inventory purchased from the prepayment will transfer to G42. Headquarters Lease Renewal In June 2024, the Company entered into an agreement to modify the lease for its headquarters located in Sunnyvale, California, to extend the term of the existing lease from December 1, 2024 to November 30, 2027. The Company expects to pay total rent of approximately $5.5 million for the extended term of the lease. The agreement also includes variable monthly charges for building operating costs. The agreement also provides for an improvement allowance for up to $0.3 million. F-36

All inter-company accounts and transactions have been eliminated. Operating results for the periods presented herein are not necessarily indicative of the results that may be expected for the entire year. Management believes that the Company’s current cash and cash equivalents and investments are adequate to meet its needs for the next 12 months from the issuance of these condensed consolidated financial statements.

Note 3 – Recent Accounting Pronouncements Not Yet Adopted In November 2023, the FASB issued ASU No. 2023-07 Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”), which enhances the disclosures required for operating segments in the Company’s annual and interim condensed consolidated financial statements. The disclosures required under ASU 2023-07 are also required for public entities with a single reportable segment. The ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company is currently evaluating the impact of this ASU on its condensed consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09 Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as information on income taxes paid. The ASU is effective for public business entities for annual periods beginning after December 15, 2024. For all other entities, the standard is effective for annual periods beginning after December 15, 2025. Early adoption is permitted. The Company is currently evaluating the impact of this ASU on its condensed consolidated financial statements.

Note 4 – Significant Accounting Policies There have been no significant changes during the six months ended June 30, 2024 and 2023 to the items disclosed in “Significant Accounting Policies” in Note 4 of the Company’s audited consolidated financial statements for the years ended December 31, 2023 and 2022 included elsewhere in this prospectus, other than as described below: F-42


CEREBRAS SYSTEMS INC. NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Restricted Cash Restricted cash includes cash and cash equivalents that are not readily available for use in the Company’s operating activities. Restricted cash is primarily attributable to a cash advance received from a customer that the Company is contractually restricted to use for the limited purposes of satisfying obligations under a certain contract with that customer. See “Customer Deposits” for additional information. Customer Deposits In April 2024, the Company entered into an agreement with G42 (the “G42 April 2024 Agreement”) pursuant to which G42, or a third party nominee affiliated with G42, indicated its intent to issue purchase orders for AI supercomputer products and services for a minimum value of $300 million. Pursuant to the G42 April 2024 Agreement, the Company received a prepayment of $300 million from G42 in May 2024 to be used for payments to third-party vendors to manufacture high performance computing infrastructure. If the purchase orders are not issued by G42, any portion of the prepayment not paid to the Company’s third-party vendors will be payable to G42 on demand and the Company’s rights to inventory purchased with the prepayment will transfer to G42. In May 2024, the Company also entered into an agreement with G42 (the “G42 May 2024 Agreement”) pursuant to which the Company agreed to certain pricing commitments with G42 through the end of 2025, and G42 agreed that it will purchase, or will cause a third party that may be affiliated or unaffiliated and under a commercial agreement with G42 to purchase, high-performance computing systems, installation, and support services in an aggregate amount of approximately $1.43 billion by completing the prepayment of such amount before February 28, 2025 and executing binding purchase orders totaling such amount. Subsequent to June 30, 2024, the Company received certain purchase orders from G42. As of June 30, 2024, the Company recorded the $300 million received pursuant to the G42 April 2024 Agreement as a customer deposit on the condensed consolidated balance sheet. See Note 16 for additional information. Deferred Offering Costs Deferred offering costs, consisting of legal, accounting, and other fees and costs relating to the Company’s planned initial public offering, are capitalized within other assets on the condensed consolidated balance sheet. The deferred offering costs will be offset against the proceeds received by the Company upon the completion of the planned initial public offering. In the event the planned initial public offering is terminated, all of the deferred offering costs will be expensed as general and administrative expense. As of June 30, 2024 and December 31, 2023, the deferred offering costs were $2.0 million and $0, respectively. Forward Contract Liability The Company determined that its obligation to issue, and the Company’s investors’ obligation to purchase, shares of Series F-1 redeemable convertible preferred stock at a fixed price in the future represented a freestanding financial instrument (“forward contract liability”) and is classified as a liability because the underlying shares of forward contract liability are redeemable upon the occurrence of certain events outside the control of the Company. This liability is measured at fair value upon initial recognition and at each subsequent reporting date through the settlement date, with changes in fair value for each reporting period recognized in other (expense) income, net on the consolidated statements of operations. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. 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 condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. F-43


CEREBRAS SYSTEMS INC. NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Areas of significant estimates include, but are not limited to, revenue recognition, including the determination of the standalone selling price (“SSP”) of performance obligations, useful life of property, plant and equipment, product warranty accruals, impairment of long-lived assets, the market value of and demand for inventory, valuation allowance on deferred income tax assets, the fair value of common stock, and other assumptions used to measure stock-based compensation, forward contract liability, and warrant liability. The Company bases its estimates on historical experience, known trends, and other market-specific or other relevant factors that it believes to be reasonable under the circumstances. On an ongoing basis, management evaluates its estimates when there are changes in circumstances, facts, and experience. Changes in estimates are recorded prospectively in the period in which they become known. Actual results could significantly differ from those estimates. Risks and Uncertainties Customer Concentration Revenue from significant customers, meaning those representing 10% or more of total revenue, was composed of one customer accounting for 87% of the Company’s revenue for the six months ended June 30, 2024. Two customers accounted for 43% and 14%, respectively, of the Company’s revenue for the six months ended June 30, 2023. Accounts receivable from significant customers, meaning those representing 10% or more of the total accounts receivable, was composed of two customers accounting for 68% and 16%, respectively, of the Company’s accounts receivable balance as of June 30, 2024. Four customers accounted for 43%, 22%, 15%, and 15%, respectively, of the Company’s accounts receivable balance as of December 31, 2023 Supplier Concentration Certain materials used by the Company in the manufacturing of its products are available from a limited number of suppliers. Shortages could occur in these materials due to an interruption of supply or increased demand in the industry. Two suppliers accounted for 26% and 15% of total purchases for the six months ended June 30, 2024. One supplier accounted for 47% of total purchases for the six months ended June 30, 2023.

Revenue recognized during the six months ended June 30, 2024 that was included in deferred revenue as of December 31, 2023 was $8.7 million. Revenue recognized during the six months ended June 30, 2023 that was included in deferred revenue as of December 31, 2022 was $1.4 million. Contract assets represent deferred cost of sales related to revenue that has not yet been recognized and unbilled receivables related to revenue that has been recognized but not yet invoiced. The balance of contract assets was $4.3 million and $0.2 million as of June 30, 2024 and December 31, 2023, respectively, in prepaid expenses and other current assets. Contract liabilities are recorded in deferred revenue and represent amounts that have been invoiced or received in advance but have not yet been recognized as revenue. Revenue allocated to remaining performance obligations that is unsatisfied (or partially unsatisfied), which includes deferred revenue and amounts that will be invoiced and recognized as revenue in future periods, was $49.0 million as of June 30, 2024. The Company expects to recognize approximately 69% of this revenue over the next 12 months and the remainder thereafter. This excludes revenue related to performance obligations for contracts with a length of one year or less.

Note 6 – Segment and Geographical Information The Company operates as one operating segment. Operating segments are defined as components of an enterprise for which separate financial information is regularly evaluated by the chief operating decision maker (“CODM”), which is the Company’s Chief Executive Officer, in deciding how to allocate resources and assess performance. The Company’s CODM evaluates the Company’s financial information and resources and assesses the performance of these resources on a consolidated basis. The Company is not organized by market and is managed and operated as one business. Accordingly, the Company does not accumulate discrete financial information with respect to separate divisions and does not have separate operating or reportable segments. Since the Company operates as one operating segment, all required financial segment information can be found in the condensed consolidated financial statements. F-45

In computing diluted earnings per share, common share equivalents are not considered in periods in which a net loss is reported, as the inclusion of the common share equivalents would be antidilutive. Since the Company was in a net loss for all periods presented in these condensed consolidated financial statements, diluted net loss per share was the same as basic net loss per share.

Note 8 – Investments The Company classifies its U.S. Treasury securities, which are accounted for as available-for-sale, and time deposits within Level 2 in the fair value hierarchy because it uses quoted market prices to the extent available or alternative pricing sources and models utilizing market observable inputs to determine fair value. There were no transfers between Level 1 and Level 2 as of June 30, 2024 and December 31, 2023. F-46

In May 2024, the Company entered into a Series F-1 redeemable convertible preferred stock purchase agreement (the “Series F-1 Purchase Agreement”) with various investors to issue up to 27,285,129 shares of the Company’s Series F-1 redeemable convertible preferred stock. Pursuant to the terms of the Series F-1 Purchase Agreement, G42 agreed to purchase approximately 22.9 million shares of the Company’s Series F-1 redeemable convertible preferred stock at $14.66 per share, for anticipated gross proceeds of $335 million (the “G42 Primary Purchase”). The closing of the G42 Primary Purchase is subject to regulatory approval, as well as the satisfaction of customary closing conditions. Pursuant to the Series F-1 Purchase Agreement, if G42, or certain third parties at the direction of G42, purchase more than $500.0 million in one purchase order, and less than $5.0 billion in the aggregate, of high-performance computing clusters (the “G42 Option Threshold”), the Company will grant G42 the option to purchase additional shares of Series F-1 redeemable convertible preferred stock (or, if such option is granted or exercised following the completion of the Company’s initial public offering, shares of the Company’s common stock), subject to the terms thereof (the “G42 Option”). The maximum number of shares that may be purchased pursuant to the G42 Option will be the quotient of (i) the total aggregate purchase price for the G42 Option, which will equal 10% of the value of the relevant purchaser order(s), divided by (ii) (A) if the G42 Option is granted and exercised prior to the completion of the Company’s initial public offering, a price per share that is 17.5% below the price per share of the Company’s then most recent arms-length sale of the Company’s redeemable convertible preferred stock (excluding the Company’s Series F-1 redeemable convertible preferred stock), or (B) if the G42 Option is granted or exercised following the completion of the Company’s initial public offering, a price per share that is 17.5% below the average closing price per share of the Company’s common stock over the 30-day period prior to the G42 Option Threshold being met. The G42 Option expires on December 31, 2025. G42’s ability to purchase shares in connection with the G42 Option is subject to regulatory approval. Additionally, an existing F-49

investor agreed to purchase approximately 3.1 million shares of the Company’s Series F-1 redeemable convertible preferred stock at a price of $14.66 per share, for anticipated gross proceeds of $45 million. The commitments made by these investors to purchase shares of the Company’s Series F-1 redeemable convertible preferred stock at a future date for a fixed price of $14.66 per share represent a forward contract between the Company and the counterparties. The forward contracts are classified as a liability and remeasured to fair value at each reporting date, with changes in fair value recorded to other (expense) income, net. The forward contract was considered to be a Level 3 liability in the fair value hierarchy due to certain unobservable inputs. The primary input in the valuation of the forward liability is the fair value of the Company’s Series F-1 redeemable convertible preferred stock which was determined in accordance with the applicable elements of the American Institute of Certified Public Accountants guide, Valuation of Privately Held Company Equity Securities Issued as Compensation and derived from a hybrid method that considered both an option pricing model (“OPM”) and the probability weighted expected return method (“PWERM”) to allocate the value among the various classes of securities to arrive at the fair value of Series F-1 redeemable convertible preferred stock. The OPM is based on the Black-Scholes-Merton option pricing model, which allows for the identification for a range of possible future outcomes, each with an associated probability. The OPM is appropriate to use when the range of possible future outcomes is difficult to predict and thus creates highly speculative forecasts. PWERM involves a forward-looking analysis of the possible future outcomes of the enterprise including an initial public offering as well as non-initial public offering market-based outcomes. As of June 30, 2024, the fair value of the Series F-1 redeemable convertible preferred stock was $15.83 per share. The following table provides a reconciliation of the beginning and ending balances for forward contract liability measured at fair value using significant unobservable inputs (in thousands):

Warrants In 2020, the Company entered into an equity arrangement with one of its customers whereby the Company issued a warrant that is exercisable for up to 68,213 shares of its Series E redeemable convertible preferred stock. The warrant is classified as a liability and remeasured to fair value and falls under Level 3 of the fair value hierarchy. As of June 30, 2024 and December 31, 2023, the warrant was valued at $1.1 million. The Company provided services and issued the warrant to the customer, and the customer paid the consideration to the Company for the provision of services. The warrant has a contractual term of seven years and an exercise price of $0.00001 per share. The customer is able to either exercise the warrants at the exercise price or convert a portion of the warrants into a number of shares of Series E redeemable convertible preferred stock adjusted to equal the fair market value, less the exercise price. The fair value of warrants is determined using a Black-Scholes option-pricing model as of the grant date. The amount representing the fair value of the equity provided to the customer from the warrant is recognized as adjustments of revenue in the consolidated statements of operations and comprehensive loss over the term of such commercial agreement or based on the achievement of certain performance targets in accordance with ASC 505-50. As of June 30, 2024, fair value of the warrant accrued was determined using the following assumptions:

Note 13 – Income Taxes The Company’s quarterly tax provision and estimate of its annual effective tax rate is subject to variation due to several factors, including variability in pre-tax income (or loss), the mix of jurisdictions to which such income (or loss) relates, changes in how the Company does business, and tax law developments. The Company’s estimated effective tax rate for the year differs from the U.S. statutory rate of 21% primarily as a result of not benefiting U.S. losses as those losses are not more likely than not to be realized, as well as its foreign operations, which are subject to tax rates that differ from those in the United States. The Company recorded an income tax expense of $319 thousand and $72 thousand for the six months ended June 30, 2024 and 2023, respectively.

Note 14 – Leases The Company’s lease obligations consist of operating leases for data centers and offices. The extension periods have not been included in the determination of the right-of-use assets or the lease liability for operating leases as the Company did not consider it reasonably certain that it would exercise these options. The Company has elected not to recognize right-of-use assets and operating lease liabilities that arise from short-term (12 months or less) leases for any class of underlying assets. The Company has elected not to separate lease and non-lease components for any class of underlying asset. In June 2024, the Company entered into an agreement to modify the lease for its headquarters located in Sunnyvale, California, to extend the term of the existing lease from December 1, 2024 to November 30, 2027. The lease is an operating lease, and the Company expects to pay total rent of approximately $5.5 million for the extended term of the lease. The agreement also includes variable monthly charges for building operating costs. In February 2024, the Company entered into a 55-month lease agreement for office space in Toronto, Canada. The lease commenced April 8, 2024, terminates March 16, 2029. The lease is an operating lease, and the Company expects to pay a total rent of $1.2 million for the term of the lease. The agreement also includes variable monthly charges for building operating costs. In November 2023, the Company entered into a 41-month lease agreement with the owner and landlord of a data center in Stockton, California. The lease commenced January 4, 2024, terminates on May 31, 2027, and is an operating lease. Monthly recurring charges for rent and power are $0.6 million per month from June 2024 through May 2026, increasing to $0.7 million per month through May 2027. The agreement also includes variable monthly F-53

Note 16 – Subsequent Events The Company has evaluated all transactions through August 29, 2024, the date these condensed consolidated financial statements were available to be issued, and for disclosure purposes, through September 30, 2024, and has determined that there are no other events, other than the following, that would require disclosure in or adjustment to these financial statements. Series F-1 and Series F-2 Financing In July 2024, the Company amended its certificate of incorporation to increase the number of authorized shares of its Series F-1 redeemable convertible preferred stock to 28,649,385 shares. In July and August 2024, the Company sold an aggregate of 2,728,512 shares of its Series F-1 redeemable convertible preferred stock at a purchase price of $14.66 per share, for aggregate proceeds of $40.0 million. In September 2024, the Company sold 3,069,577 shares of its Series F-1 redeemable convertible preferred stock to an investor at a purchase price of $14.66 per share, for aggregate proceeds of $45.0 million. The Company amended and restated the Series F-1 Purchase Agreement in September 2024. Pursuant to the Series F-1 Purchase Agreement, as amended, G42 agreed to purchase an aggregate of approximately 22.9 million shares of the Company’s non-voting Series F-2 redeemable convertible preferred stock (or, if purchased following the completion of the Company’s initial public offering, shares of the Company’s non-voting Class N common stock) at a purchase price of $14.66 per share, for anticipated gross proceeds to the Company of $335.0 million. G42 has committed to purchase these shares by April 15, 2025. Each share of the non-voting Class N common stock is convertible at any time at the option of the holder into one share of Class A common stock. G42 has agreed to not convert its shares of Class N common stock before July 31, 2025. Additionally, pursuant to the amended and restated Series F-1 Purchase Agreement, under certain circumstances, G42 will have the option to purchase additional shares of the Company’s Series F-2 redeemable convertible preferred stock (or, if purchased following the completion of the Company’s initial public offering, shares of the Company’s Class N common stock) at a 17.5% discount to the then-fair market value of the Company’s shares of Class A common stock. Customer Deposits In July 2024, the Company received a purchase order from G42 for the sale of $178.7 million of its high-performance computing systems, including installation and support services. Additionally, the Company entered into a new agreement, and modified an existing agreement, pursuant to which it agreed to provide operation and management services for certain high-performance computing systems purchased by G42. The fees to be paid by G42 under these agreements will be deducted from the initial $300.0 million prepayment received as part of the G42 April 2024 Agreement, and the $178.7 million fee for a July 2024 purchase order from G42 fulfills a portion of the prepayment and purchase order commitments under the G42 May 2024 Agreement. In September 2024, the Company received a purchase order and prepayment from a customer for high performance computing systems, installations, and support services for a total of $350.0 million. The prepayment will be used for payments to third-party vendors to manufacture high performance computing infrastructure and fulfills a portion of the purchase order commitments under the G42 May 2024 Agreement.

Item 14. Indemnification of Directors and Officers Section 145 of the Delaware General Corporation Law provides that a corporation may indemnify directors and officers as well as other employees and individuals against expenses (including attorneys’ fees), judgments, fines, and amounts paid in settlement actually and reasonably incurred by such person in connection with any threatened, pending, or completed actions, suits, or proceedings in which such person is made a party by reason of such person being or having been a director, officer, employee, or agent to the registrant. The Delaware General Corporation Law provides that Section 145 is not exclusive of other rights to which those seeking indemnification may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors, or otherwise. Article 9 of the registrant’s amended and restated certificate of incorporation, to be in effect immediately prior to the completion of this offering, provides for indemnification by the registrant of its directors, officers, and employees to the fullest extent permitted by the Delaware General Corporation Law. The registrant has entered or will enter into indemnification agreements with each of its current directors, executive officers, and certain other officers to provide these directors and officers additional contractual assurances regarding the scope of the indemnification set forth in the registrant’s amended and restated certificate of incorporation and amended and restated bylaws, each to be in effect immediately prior to the completion of this offering, and to provide additional procedural protections. There is no pending litigation or proceeding involving a director or executive officer of the registrant for which indemnification is sought. Section 102(b)(7) of the Delaware General Corporation Law permits a corporation to provide in its certificate of incorporation that a director or officer of the corporation shall not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, except for liability (i) for any breach of the director’s or officer’s duty of loyalty to the corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) in the case of directors, for unlawful payments of dividends or unlawful stock repurchases, redemptions, or other distributions, or (iv) for any transaction from which the director or officer derived an improper personal benefit, provided that II-1


officers may not be indemnified for actions by or in the right of the corporation. The registrant’s amended and restated certificate of incorporation, to be in effect immediately prior to the completion of this offering, provides for such limitation of liability. The registrant maintains standard policies of insurance under which coverage is provided (a) to its directors and officers against loss rising from claims made by reason of breach of duty or other wrongful act and (b) to the registrant with respect to payments that may be made by the registrant to such officers and directors pursuant to the above indemnification provision or otherwise as a matter of law. The proposed form of underwriting agreement to be filed as Exhibit 1.1 to this registration statement provides for indemnification of directors and officers of the registrant by the underwriters against certain liabilities.

Item 15. Recent Sales of Unregistered Securities Since January 1, 2021, the registrant made sales of the following unregistered securities: Option and Common Stock Issuances Since January 1, 2021, the registrant granted to its employees, consultants, and other service providers options to purchase an aggregate of 36,325,064 shares of its Class A common stock under its 2016 Equity Incentive Plan (as amended, the “2016 Plan”), at exercise prices ranging from $2.40 to $13.01 per share. Since January 1, 2021, the registrant issued and sold to its employees, consultants, and other service providers an aggregate of 13,261,206 shares of its Class A common stock upon the exercise of stock options under its 2016 Plan, at exercise prices ranging from $0.09 to $11.51 per share, for a weighted-average exercise price of $2.93. Since January 1, 2021, the registrant granted to its employees, consultants, and other service providers restricted stock units covering an aggregate of 4,124,851 shares of its Class A common stock under its 2016 Plan. In August 2022, the registrant sold an aggregate of 599,880 shares of its Class A common stock to an accredited investor at a purchase price of $16.7525 per share, for an aggregate purchase price of $10.0 million. Redeemable Convertible Preferred Stock Issuances Between October and December 2021, the registrant issued and sold an aggregate of 9,168,419 shares of its Series F redeemable convertible preferred stock to eight accredited investors at a purchase price of $27.7448 per share, for an aggregate purchase price of $254.4 million. In July and August 2024, the registrant sold an aggregate of 2,728,512 shares of its Series F-1 redeemable convertible preferred stock to five accredited investors at a purchase price of $14.66 per share, for an aggregate purchase price of $40.0 million. In September 2024, the registrant issued and sold 3,069,577 shares of its Series F-1 redeemable convertible preferred stock to an accredited investor at a purchase price of $14.66 per share, for a purchase price of $45.0 million. In August 2024, the registrant issued 68,213 shares of its Series E redeemable convertible preferred stock to an accredited investor pursuant to a warrant with an exercise price of $0.00001 per share. The registrant believes these offers, sales, and issuances were exempt from registration under the Securities Act in reliance upon Section 4(a)(2) of the Securities Act or Regulation D promulgated thereunder, or Rule 701 promulgated under the Securities Act as transactions by an issuer not involving a public offering or pursuant to benefit plans and contracts relating to compensation as provided under Rule 701. The recipients of the securities in each of these transactions represented their intentions to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof, and appropriate legends were placed upon the stock II-2


certificates issued in these transactions. All recipients had adequate access, through their relationships with the registrant, to information about the registrant.

Item 16. Exhibits and Financial Statement Schedules See the Exhibit Index attached to this registration statement, which Exhibit Index is incorporated herein by reference. Schedules not listed above have been omitted because the information required to be set forth therein is not applicable or is shown in the financial statements or notes thereto.

Item 17. Undertakings (a)Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit, or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered hereunder, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question of whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. (b)The undersigned registrant hereby undertakes that: (1)For purposes of determining any liability under the Securities Act, the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective. (2)For the purpose of determining any liability under the Securities Act, each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
