SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q (this “Quarterly Report”) of Oklo Inc. (“Oklo,” the “Company,” “we,” “our,” and “us”) contains certain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Forward-looking statements relate to future events or future performance and include, without limitation, statements concerning our business strategy, future revenues, market growth, capital requirements, product introductions, expansion plans and the adequacy of our funding. Other statements contained in this Quarterly Report that are not historical facts are also forward-looking statements. We have tried, wherever possible, to identify forward-looking statements by terminology such as “may,” “will,” “could,” “should,” “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates,” “continue,” “might,” “possible,” “potential,” “predict,” “project,” “goal,” “would,” “commit,” and other stylistic variants denoting forward-looking statements.

We caution investors that any forward-looking statements presented in this Quarterly Report, or that we may make orally or in writing from time to time, are based on information currently available, as well as our beliefs and assumptions. The actual outcome related to forward-looking statements will be affected by known and unknown risks, trends, uncertainties, and factors that are beyond our control or ability to predict. Although we believe that our assumptions are reasonable, they are not guarantees of future performance, and some will inevitably prove to be incorrect. As a result, our actual future results can be expected to differ from our expectations, and those differences may be material. Accordingly, investors should use caution in relying on forward-looking statements, which are based only on known results and trends at the time they are made, to anticipate future results or trends.

The forward-looking statements contained in this Quarterly Report are based on current expectations and beliefs concerning future developments and their potential effects on us. There can be no assurance that future developments affecting us will be those that we have anticipated. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond our control), or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. These risks and uncertainties include, but are not limited to: risks related to the development and deployment of Oklo’s powerhouses; the risk that Oklo is pursuing an emerging market, with no commercial project operating, regulatory uncertainties; risks related to acquisitions, divestitures, or joint ventures we may engage in; the potential need for financing to construct plants, market, financial, political and legal conditions; the effects of competition; risks related to accessing high-assay low-enriched uranium ("HALEU") and recycled fuels; risks related to our supply chain; risks related to power purchase agreements; risks related to human capital; risks related to our intellectual property; risks related to cybersecurity and data privacy; changes in applicable laws or regulations, including tariffs; the outcome of any government and regulatory proceedings and investigations and inquiries; and those factors in the other documents filed by Oklo from time to time with the U.S. Securities and Exchange Commission (“SEC”). The discussion in this Quarterly Report should be read in conjunction with the condensed consolidated financial statements and notes thereto included in Item 1 of this Quarterly Report. Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. We undertake no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws.

This Quarterly Report and all subsequent written and oral forward-looking statements attributable to us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this section. We do not undertake any obligation to release publicly any revisions to our forward-looking statements to reflect events or circumstances after the date of this Quarterly Report, except as may be required by law.

Notes to Condensed Consolidated Financial Statements

(in thousands, except share data or otherwise stated)

1.Nature of Operations and Organization

Oklo Inc. (the “Company” or “Oklo”), conducts its operations through its subsidiary Oklo Technologies, Inc., a Delaware corporation incorporated on July 3, 2013.

The Company is developing advanced fission power plants to provide clean, reliable, and affordable energy at scale and plans to commercialize its metal-fueled fast reactor technology with the Aurora powerhouse product line. The Aurora product line is designed to produce up to 15 and 75 megawatts of electricity (“MWe”) on both recycled nuclear fuel and fresh fuel. Oklo’s advanced fission technology has a history of successful operation, first demonstrated by the Experimental Breeder Reactor-II, which sold and supplied power to the grid and showed effective waste recycling capabilities over 30 years of operation. Furthermore, Oklo has achieved several significant deployment and regulatory milestones, including securing a site use permit from the U.S. Department of Energy (“DOE”) for the Idaho National Laboratory (“INL”) Site and a fuel award from INL for a commercial-scale advanced fission power plant in Idaho.

On May 9, 2024, the Company consummated a business combination pursuant to an Agreement and Plan of Merger and Reorganization dated July 11, 2023 (as amended, modified, supplemented or waived, the “Merger Agreement”), by and among AltC Acquisition Corp. ("AltC"), and Oklo Technologies, Inc. (the "Recapitalization") (further details are provided below). Before the Recapitalization, Oklo Technologies, Inc. was formerly known as Oklo Inc. (referred to herein as "Legacy Oklo"). Upon consummation of the Recapitalization, AltC changed its name to Oklo Inc.

In connection with the Recapitalization consummated on May 9, 2024 that was accounted for as a reverse recapitalization, where Legacy Oklo was determined to be the accounting acquirer, the common stock has been recast to reflect the retroactive application of the reverse recapitalization. Under this method of accounting, AltC was treated as the “acquired” company for financial reporting purposes. Accordingly, for accounting purposes, the Recapitalization was treated as the equivalent of Legacy Oklo issuing stock for the net assets of AltC, accompanied by a recapitalization. Results of operations prior to the Recapitalization are presented as belonging to Legacy Oklo. The Recapitalization had no effect on reported net loss, cash flows, or total assets as previously reported.

The Company’s Class A common stock ("common stock") commenced trading on the New York Stock Exchange (“NYSE”) under the symbol “OKLO” on May 10, 2024.

On February 28, 2025, the Company's entered into a stock purchase agreement pursuant to which it acquired 100% of the common stock outstanding of Atomic Alchemy, Inc. ("Atomic Alchemy"), by way of statutory merger, to combine Oklo’s expertise in building and operating fast reactors and nuclear fuel recycling with Atomic Alchemy’s expertise in its radioisotope business to meet the increasing demands for radioisotopes in medical, energy, industry, defense and artificial intelligence applications (further details are provided in Note 3).

Liquidity and Capital Resources

As of March 31, 2025, the Company's cash, cash equivalents and marketable debt securities were $260,688. The Company continues to incur significant operating losses. For the three months ended March 31, 2025, the Company had a net loss of $9,810, loss from operations of $17,874, and net cash used in operating activities of $12,243. As of March 31, 2025, the Company had an accumulated deficit of $144,919.

The Company will utilize its existing cash, cash equivalents and marketable debt securities to fund its powerhouses, radioisotopes business, operations and growth plans and believes that its existing cash, cash equivalents and marketable debt securities will be sufficient to fund its operations for the one-year period following the issuance date of these condensed consolidated financial statements.

2.Summary of Significant Accounting Policies

Basis of Presentation

Table of Contents

The accompanying unaudited condensed consolidated financial statements and accompanying notes are prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial reporting.

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Articles 8 and 10 of Regulation S-X of the U.S. Securities and Exchange Commission (“SEC”). Certain information or footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, it does not include all the information and footnotes necessary for a complete presentation of financial position, results of operations, or cash flows. The information herein should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024, which was filed on March 24, 2025. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair statement of the financial position, operating results, and cash flows for the periods presented.

Segment Information

The Company has viewed its financial information on an aggregate basis for the purposes of evaluating financial performance and allocating the Company’s resources. The Company's principal business consists primarily of research and development activities for its planned powerhouses, radioisotopes business and nuclear recycling facilities. Accordingly, the Company has determined that it operates in one reportable segment. For more information about the Company's single operating and reportable segment, see Note 13.

Principles of Consolidation

The condensed consolidated financial statements include the Company’s accounts and those of its wholly owned subsidiaries Oklo Technologies, Inc., Atomic Alchemy, Inc., and Oklo Power LLC. All intercompany transactions and balances have been eliminated.

Use of Estimates

Preparation of financial statements in conformity with U.S. GAAP requires management to make estimates, judgments, and assumptions that affect the amounts reported and disclosed in the condensed consolidated financial statements and accompanying notes. Actual results could differ materially from these estimates. On an ongoing basis, the Company evaluates its estimates, including those related to the valuation of the operating lease liabilities and operating right-of-use assets, useful lives of property and equipment, stock-based compensation expense, valuation allowance on deferred tax assets, and fair value of acquired intangible assets and goodwill. These estimates, judgments, and assumptions are based on current and expected economic conditions, historical data, and experience available at the date of the accompanying condensed consolidated financial statements, and various other factors that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities.

Risk and Uncertainties

The Company is subject to continuing risks and uncertainties in connection with the current macroeconomic environment, including as a result of inflation, instability in the global banking system, trade policy (including tariffs, export controls, and sanctions), and geopolitical factors, including the ongoing conflicts in Ukraine and Israel. At this point, the extent to which these effects may impact the Company’s future financial condition or results of operations is uncertain, and as of the date of issuance of these financial statements, the Company is not aware of any specific event or circumstance that would require the update of any estimates or judgments or an adjustment of the carrying value of any assets or liabilities. Given the nature of the business, the ongoing conflicts in Ukraine and Israel have not had a specific impact on the Company’s financial performance. These estimates may change as new events occur and additional information is obtained and will be recognized in the financial statements as soon as they become known.

Net Loss Per Common Share

The Company’s basic net loss per share of common stock is computed based on the average number of outstanding shares of common stock for the period, by dividing the net loss by the weighted-average number of shares of common stock

Table of Contents

outstanding for the period, without consideration for potential dilutive securities. Diluted net loss per share of common stock is computed by dividing net loss by the weighted-average number of shares of common stock and common share equivalents of potentially dilutive securities outstanding for the period. Potentially dilutive securities include common stock equivalents. Since the Company was in a loss position for the periods presented, basic net loss per share of common stock is the same as diluted net loss per share of common stock since the effects of potentially dilutive securities are antidilutive.

The outstanding potentially dilutive common stock equivalents for: (1) options to purchase shares of common stock of 9,151,461 and 10,432,749 as of March 31, 2025 and 2024, respectively, (2) unvested restricted stock of 640,125 and 0, and (3) unvested restricted stock units of 1,624,743 and 0, respectively, have been excluded from the calculation of diluted net loss per common share due to their anti-dilutive effect.

Emerging Growth Company Status

The Company is an emerging growth company ("EGC") as defined in the Jumpstart Our Business Startups Act (“JOBS Act”). The JOBS Act provides emerging growth companies with certain exemptions from public company reporting requirements for up to five fiscal years while a company remains an emerging growth company. As part of these exemptions, the Company has reduced disclosure obligations such as for executive compensation, and it is not required to comply with auditor attestation requirements from Section 404(b) of the Sarbanes-Oxley Act of 2002, as amended, regarding its internal control over financial reporting. Additionally, the JOBS Act has allowed the Company the option to delay adoption of new or revised financial accounting standards until private companies are required to comply with new or revised financial accounting standards. The Company's EGC status is expected to expire on December 31, 2026, although this could occur earlier if the Company fails to meet the required EGC qualifications. The Company will perform an annual assessment as of June 30, 2025 to determine ongoing eligibility for EGC status.

Indefinite-Lived Intangible Assets

Intangible assets with indefinite lives consist of in-process research and development (“IPR&D”) from the Company's acquisition of Atomic Alchemy (further details are provided under the heading Atomic Alchemy in Note 3). These assets are tested annually for impairment until completion. If potential impairment is identified, the process of evaluating the potential impairment of these assets involves significant judgment regarding estimates of the future cash flows associated with each asset.

Goodwill

Goodwill represents the excess purchase consideration of an acquired business over the estimated fair value of the net assets acquired and is not amortized. Goodwill is evaluated for impairment annually, or whenever events or circumstances indicate that the carrying amount may not be recoverable. If the carrying amount of the Company's reportable segment exceeds its fair value, an impairment loss is recognized for any excess of the carrying amount of the reportable segment's goodwill over the implied fair value of the goodwill.

Recently Issued and Not Adopted Accounting Standards

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which will require the Company to disclose specified additional information in its income tax rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold. ASU 2023-09 will also require the Company to disaggregate its income taxes paid disclosure by federal, state and foreign taxes, with further disaggregation required for significant individual jurisdictions. The provisions of ASU 2023-09 are effective for annual periods beginning after December 15, 2024; early adoption is permitted using either a prospective or retrospective transition method. The Company expects ASU 2023-09 to require additional disclosures in the notes to its condensed consolidated financial statements.

In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which will require disaggregated disclosures in the notes to the financial statements of certain categories of expenses, including purchases of inventory, employee compensation, and depreciation and amortization, that are included in expense line items within the statement of operations. ASU 2024-03 will be applied prospectively; however, retrospective application is permitted. ASU 2024-03, as clarified in ASU 2025-01, Clarifying the Effective Date, requires public business entities to adopt the guidance

Table of Contents

in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is evaluating the impact of ASU 2024-03 on its disclosures in the notes to its financial statements.

3.Business Combination

On February 28, 2025, the Company acquired Atomic Alchemy's common stock in a business combination for its radioisotope business located in the United States. The purchase price of $28,424 was comprised of (i) a cash portion, paid at the acquisition date of $900, net of cash acquired, to certain Atomic Alchemy equity holders for their respective portion of the consideration and (ii) the issuance of 820,840 shares of the Company's common stock representing stock consideration in exchange of Atomic Alchemy's common stock. At the acquisition date, the Company's common stock public trading price of $33.39 per share was used to measure the stock consideration of $27,408.

In connection with the business combination, the Company issued 274,339 shares of its common stock, subject to certain lock-up provisions, vesting conditions and substantial risk of forfeiture, representing postcombination services, pursuant to an employment agreement and vesting agreement.

The composition of the purchase price is as follows:


Cash	$	1,016
Common stock	27,408
Total purchase consideration	$	28,424

The Company incurred $332 in transaction costs related to the acquisition, which primarily consisted of legal and accounting expenses. The acquisition-related expenses were recorded in general and administrative expenses on the condensed consolidated statements of operations.

The estimated fair values of assets acquired and liabilities assumed are preliminary and the Company continues to gather information to properly identify and measure all acquired assets and liabilities. The preliminary purchase price allocation resulted in the following amounts being allocated to the assets acquired and liabilities assumed at the acquisition date based upon their respective fair values as summarized below:


Cash	$	116
Prepaid expenses	99
Property and equipment	40
Operating lease right-of-use assets	19
Indefinite-lived intangible assets	27,500
Goodwill	6,720
Operating lease liability	(19)
Other current liabilities	(268)
Deferred tax liabilities	(5,783)
Net assets acquired	$	28,424

The Company utilized an independent appraisal firm to assist in the determination of the fair values of the assets acquired and liabilities assumed, which required certain significant management assumptions and estimates. The preliminary fair value of the indefinite-lived intangible assets representing in-process research and development projects ("IPR&D") were valued using a pre-tax royalty for the hypothetical use of a trade name for a selected royalty rate based on a market licensing agreement bench marketing analysis.

The IPR&D consisted of two separate projects, Abundantia and Meitner. Abundantia’s preliminary fair value assigned of $4,600 is expected to produce revenue potentially as early as 2026 from the sale of purified radium and other desired radioisotopes produced via irradiation. Meitner’s preliminary fair value of $22,900 is a later stage project which will produce for sale isotopes that are prepared and irradiated into radioisotopes in Versatile Isotope Production Reactors (“VIPR”), which is a thermal pool-type nuclear reactor. Each project has a different risk profile, cash flows and its own unique process. Abundantia is expected to produce revenue upon completion of a lab with its fair value determined using a specific risk-adjusted discount rate applied to its potential cash flows, subject to certain possession permit required by the

NRC. Meitner is expected to produce revenue once a facility is constructed with its fair value determined using a specific risk-adjusted discount rate applied to its cash flows, subject to approval of an application for a construction license and operating license by the NRC. There was no estimated useful life assigned given the assets are IPR&D.

The excess of the purchase price over the fair value amounts assigned to the assets acquired and liabilities assumed represents goodwill from the acquisition. Goodwill is recorded as a noncurrent asset that is not amortized but is subject to an annual review for impairment. Goodwill is not deductible for tax purposes.

Supplemental Pro Forma Financial Information

The results of operations of Atomic Alchemy are included in the condensed consolidated financial statements beginning on February 28, 2025, the acquisition date. For the three months ended March 31, 2025, the condensed consolidated statements of operations include no revenue and an immaterial amount of loss from operations for Atomic Alchemy. The Company has not presented supplemental pro forma revenue (no revenue has been generated) and earnings of the combined business as the acquisition of Atomic Alchemy is not material to the Company's condensed consolidated financial statements.

7.Simple Agreements for Future Equity

The Company issued simple agreements for future equity (the “Legacy Oklo SAFEs”) to investors (the “SAFEs”) prior to the Recapitalization, where the SAFEs allowed investors to purchase equity at a negotiated price at the time of each investor’s entry into such agreement with each investor receiving equity in the future with no set time for conversion. The SAFEs converted in connection with the Recapitalization. Prior to the conversion, the SAFEs were classified as a liability under ASC 480, Distinguishing Liabilities from Equity.

No SAFEs were issued during the three months ended March 31, 2025. During the three months ended March 31, 2024, the Company issued SAFE notes in exchange for aggregate cash proceeds of $10,232.

Fair Value Measurements

Prior to the SAFEs conversion, they were measured at fair value on a recurring basis using significant unobservable inputs based upon a three-tier hierarchy under the authoritative guidance (Level 3) at each reporting period-end, with changes in the fair value recognized on the condensed consolidated statements of operations. The change in fair value during the three months ended March 31, 2024 was $16,793, as reflected on the condensed statements of operations.

8.Right of First Refusal Liability

On February 16, 2024, the Company entered into a letter of intent (the “LOI”) with an unrelated third party (the “third party”) for the purchase of power from the Company’s planned powerhouses to serve certain data centers in the U.S. on a 20-year timeline, and at a rate to be formally specified in one or more future Power Purchase Agreement(s) (each a “PPA”) (subject to the requirement that the price meets the market rate, discount and most favored nation terms contained in the agreement). In addition, the third party will have the right to renew and extend PPAs for additional 20-year terms.

The LOI provides for the third party to have a continuing right of first refusal for a period of thirty-six (36) months following its execution to purchase energy output produced by certain powerhouses developed by the Company in the U.S., subject to certain provisions and excluded powerhouses, for power capacity of no less than 100 MWe of energy output and up to cumulative maximum of 500 MWe of total energy output (the “ROFR”). In exchange for the ROFR and other rights contained in the LOI, in March 2024, the third party paid the Company $25,000 (the “Payment”). In connection with the Payment, the Company agreed to supply power at a discount to the most favored nation pricing that the Company is required to provide to the third party in a future PPA (location to be determined); provided, that pricing set out in a PPA will include an additional discount if needed such that the total savings against most favored nation pricing over the course of the PPA is equivalent to the Payment. The Payment is effectively a nonrefundable upfront payment that will be attributed to future power delivery. The third party can assign its rights under the LOI, in whole or in part, at any time. As of March 31, 2025, the outstanding balance under the right of first refusal liability was $25,000, as reflected on the condensed consolidated balance sheets.

9.Stockholders’ Equity (Deficit)

Pursuant to the Second Amended and Restated Certificate of Incorporation of the Company, the Company is authorized to issue 501,000,000 shares of all classes of capital stock consisting of (i) 500,000,000 shares of common stock, par value of $0.0001 per share and (ii) 1,000,000 shares of preferred stock, par value of $0.0001 per share. Subject to the special rights of the holders of any outstanding series of preferred stock, the number shares of preferred stock may be increased or decreased (but not below the number of shares then outstanding) by affirmative vote of the holders of a majority of the stock of the Company entitled to vote. There are no shares of preferred stock issued and outstanding.

Issuance of Common Stock – During the three months ended March 31, 2025 and 2024, the Company issued shares of its common stock upon the exercise of stock options totaling 318,921 and 1,345,625, respectively, with proceeds of $720 and $440, respectively, as reflected on the condensed consolidated statements of stockholders' equity.

Table of Contents

Restricted Stock Units – The Company issued, in connection with the vesting of restricted stock units, 134,832 shares of the Company’s common stock during the three months ended March 31, 2025, as reflected on the condensed consolidated statements of stockholders’ equity.

Common Stock Withheld for Taxes – The Company withheld 66,724 shares its common stock upon issuance of vested restricted units, representing a payment for taxes of $1,595 during the three months ended March 31, 2025, as reflected on the consolidated statements of stockholders’ equity.

10.Stock-Based Compensation

Stock-based compensation expense charged to operations is summarized as follows:


	Three Months Ended March 31,
		2025		2024
Research and development		$	973	$	394
General and administrative		1,338		273
Total costs charged to operations		$	2,311	$	667

During the three months ended March 31, 2025, approximately 740,000 awards were granted to acquire shares of the Company's common stock, consisting of restricted stock and restricted stock units, in connection with stock-based compensation arrangements with a grant date fair market value of approximately of $26,000.

Unrecognized compensation expense and expected weighted-average period to be recognized related to the stock-based compensation awards as of March 31, 2025 were as follows:


	Restricted Stock		Option Awards		Totals
Unrecognized compensation cost	$	33,098	$	8,861	$	41,959
Weighted-average period over which cost is expected to be recognized (in years)	3.45		3.50		3.46

11.Income Taxes

The provision for income taxes in interim periods is determined using an estimate of the Company’s annual effective tax rate, adjusted for discrete items, that arise during the period. Each quarter, the Company updates its estimate of its annual effective tax rate, and if the estimated annual effective tax rate changes, the Company makes a cumulative adjustment in such period. The quarterly provision for income taxes, and estimate of the Company’s annual effective tax rate, are subject to variation due to several factors, including variability in pre-tax income (or loss), the mix of jurisdictions to which such income relates, changes in how the Company conducts business, and tax law developments.

The Company's effective income tax rate for the three months ended March 31, 2025 and 2024 was 30.3% and 0.0%, respectively.

The realization of deferred tax assets is dependent upon a variety of factors, including the generation of future taxable income, the reversal of deferred tax liabilities, and tax planning strategies. During the three months ended March 31, 2025 and 2024, the Company recorded an income tax benefit of $4,411 and $0, respectively, as a result of discrete items that occured in the interim period, which caused the quarterly and year-to-date effective tax rate (“ETR”) to change from the Company’s historical annual ETR. Based upon the Company’s historical operating losses and the uncertainty of future taxable income, the Company had provided a valuation allowance against most of the deferred tax assets as of March 31, 2025 and 2024.

As of March 31, 2025 and 2024, the Company had unrecognized tax benefits related to federal research credit carryforwards, of which, if fully recognized in the future would have no impact to the ETR and would result in an adjustment to the valuation allowance. No interest and penalties related to the unrecognized tax benefits are accrued.

12.Commitments and Contingencies

Table of Contents

Contract Commitments

The Company enters into contracts in the normal course of business with third-party contract research organizations, contract development and manufacturing organizations and other service providers and vendors. These contracts generally provide for termination on notice and, therefore, are cancellable contracts and not considered contractual obligations and commitments.

Lease Option Agreement

The Company entered into a non-assignable (unless agreed to the parties) lease option agreement (the “Lease Option”) where it agreed to pay $10 per month (the “option payment(s)”), starting on January 1, 2025 and automatically expiring on January 1, 2026 (the “option term”). The Company may terminate the Lease Option after July 1, 2025 with one-month written notice. As consideration for the Lease Option, the Company is required to pay $70 if the Company exercises its early termination provision, otherwise the required payments will be $120 during the option term. As consideration for the option payment(s), the Company has an exclusive right to enter into a definitive lease agreement for certain property during the option term. If a definitive lease agreement is entered into during the option term, the option payment(s) will be credited against the required lease payments under the definitive lease agreement, otherwise they will be non-refundable except for a default under the Lease Option.

Contingencies

From time to time, the Company may become involved in litigation matters arising in the ordinary course of business. The Company is not a party to any legal proceedings, nor is it aware of any material pending or threatened litigation. There were no contingent liabilities as of March 31, 2025.

13.Segment Information

The Company reviews consolidated results to assess performance, make decisions, and allocates operating and capital resources of the Company as a whole; therefore, there is only one reportable segment. The Company uses net loss to allocate resources, along with using that measure as a basis for evaluating financial performance by comparing the actual results with historical budgets.

Significant segment expenses included within reported measure of segment profit or loss are research and development and general and administrative. Other segment items are represented by change in fair value of simple agreements for future equity, interest and dividend income and income taxes.

The condensed consolidated statements of operations for the three months ended March 31, 2025 and 2024, reflect the significant segment expenses and other segment items, as well as the condensed consolidated balance sheets as of March 31, 2025 and December 31, 2024, for the one reportable segment.

14.Subsequent Events

The Company performed an evaluation of subsequent events through the date of filing of these condensed consolidated financial statements with the SEC. There were no material subsequent events which affected, or could affect, the amounts or disclosures on the condensed consolidated financial statements.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations for the three months ended March 31, 2025 and 2024, should be read together with our unaudited condensed consolidated financial statements and related notes included elsewhere in this Quarterly Report and in conjunction with the audited consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, The following discussion contains “forward-looking statements” that reflect our future plans, estimates, beliefs and expected performance. Our actual results may differ materially from those currently anticipated and expressed in such forward-looking statements as a result of a number of factors. We caution that assumptions, expectations, projections, intentions or beliefs about future events may, and often do, vary from actual results and the differences can be material. Please see “Special Note Regarding Forward-Looking Statements.”

Overview

We were founded in 2013 with the goal of revolutionizing the energy landscape by developing clean, reliable, affordable energy solutions at scale. According to the International Energy Agency, global electricity production is expected to increase over 80% by 2050 driven by electrification of buildings, transportation and industry, increased use of air conditioning in the developing world and increased consumption from data centers. Our business addresses this demand by producing electricity and heat from our Aurora powerhouses which can run on fresh or recycled nuclear fuel. We are also commercializing nuclear fuel recycling technology that can convert nuclear waste into useable fuel for our reactors.

We are developing next-generation fast fission power plants called “powerhouses.” In our differentiated build, own, and operate business model, we plan to sell power in the forms of electricity and heat directly to customers, which we believe can allow for fast-tracked customer adoption. In addition, we are a leader in the nuclear industry in the development of fuel recycling, which can unlock the energy content of used fuel; we also believe this business unit can complement our market position by vertically integrating and securing our fuel supply chain.

The fast fission reactor technology we are commercializing was demonstrated by the Experimental Breeder Reactor-II (“EBR-II”), a fast fission plant that was operated by the U.S. government for 30 years. Our powerhouse product line, called the “Aurora,” builds on this legacy of proven and demonstrated technology. Our Aurora powerhouse product line is designed to be inherently safe, to be able to run on fresh or recycled fuel, and to produce 15-75 megawatts electric (“MWe”) and has the potential to expand powerhouse size to produce 100 MWe and higher. Because the Aurora powerhouses are designed to operate by harnessing the power of high-energy, or “fast,” neutrons, they are expected to be able to tap into the vast energy reserves remaining in existing used nuclear fuel from conventional nuclear power plants, which can only use approximately 5% of energy content stored in nuclear fuel before needing to refuel. The U.S. nuclear power industry has produced approximately 20% of U.S. electricity over the last 50 years and generated over 90,000 metric tons of nuclear waste, which can fit on a football field 10 yards high. The energy reserves in existing U.S. nuclear waste that are made accessible through Oklo's fast fission reactor technology are equivalent to approximately 1.2 trillion barrels of oil equivalent (BOE), nearly five times the oil reserves of Saudi Arabia. Fission is an energy dense process, producing approximately 50 million times more energy than combustion.

We have achieved several significant deployment and regulatory milestones for our first Aurora powerhouse. Notably, we secured a site use permit from the U.S. Department of Energy (“DOE”) for the Idaho National Laboratory (“INL”) site and received a fuel award from INL for a commercial Aurora powerhouse in Idaho. The DOE and INL have completed the environmental compliance process addressing the DOE requirements for site characterization at our first commercial advanced fission power plant site at the INL. This process, resulting in an Environmental Compliance Permit, marks a milestone as we advance our plans to deliver the first commercial advanced fission power plant in the United States. On September 25, 2024, we announced the finalization of a Memorandum of Agreement (“MOA”) with the DOE Idaho Operations Office. This MOA grants Oklo access to conduct site investigations at the identified preferred site in Idaho, marking a key step toward the next phase of site preparation and construction.

We announced plans and entered into a land rights agreement for two additional Aurora powerhouses in southern Ohio. Furthermore, we have been tentatively selected to provide electricity and heat to Eielson Air Force Base. Our robust pipeline of potential customer engagements spans a number of industries. We have signed non-binding letters of intent with Equinix, Diamondback Energy, and Prometheus Hyperscale (formerly Wyoming Hyperscale). In December 2024, we signed a 12 gigawatt (GW) Master Power Agreement with Switch data centers, one of the largest corporate power purchase agreements in history. We also executed two other letters of intent to provide an additional 750 MWe of energy for data

center customers, which could bring our current total order book of Aurora powerhouses to approximately 14,100 MWe in capacity - nearly a 2,000% increase since our business combination announcement in July 2023. The market interest in our solutions exemplifies the potential demand for the size range of the Aurora powerhouse product line and our differentiated business model. The deployment of our first Aurora powerhouse is targeted for completion in late 2027 or early 2028.

In addition to deployment milestones, we have made significant progress in our nuclear fuel recycling efforts and in securing fuel. The DOE has reviewed and approved Oklo's Safety Design Strategy and the Conceptual Safety Design Report for Oklo's Aurora Fuel Fabrication Facility at INL, key milestones as Oklo advances toward its goal of utilizing recovered nuclear material to fuel its first commercial Aurora powerhouse. We successfully completed the first end-to-end demonstration of the key stages of our advanced fuel recycling process, in collaboration with Argonne and INL. This marks a significant step forward in scaling up fuel recycling capabilities and deploying a commercial-scale recycling facility.

Our Business Model

Our primary product will be the energy produced from our Aurora powerhouses once operational. Our planned business model is to sell the energy to customers via power purchase agreements (“PPAs”), as opposed to selling our powerhouse designs. This business model allows for recurring revenue, provides the opportunity to capture profitability upon improved operational efficiency, and enables novel project financing structures. This business model sets us apart from the traditional nuclear power industry that typically sells reactors to large scale utility customers and not power. Selling power via PPAs is a common practice within the renewable energy and utilities sectors and indicates that this business model could be feasible for power plants within the size range targeted by our Aurora product line (i.e., starting with 15 MWe and 75 MWe, and ranging upward to anticipated sizes of 100 MWe and higher).

The traditional nuclear power industry comprises developers of large (ranging from approximately 600 MWe to over 1,000 MWe) light water reactors that sell or license their reactor designs to large utilities that then construct and operate the nuclear power plant. The developer’s focus on regulatory approval of the design may lock in certain lifecycle regulatory costs that are realized by the owner-operator during construction and operations. As a result, lifecycle cost implications are generally not addressed cohesively between the developer and the owner-operator, and the regulatory strategy does not holistically implement the lifecycle benefits of the technology’s inherent safety characteristics. The advanced fission industry has largely followed the historical blueprint of developers seeking design certifications or approvals, and utilities bearing the future burden of licensing for construction and operations. While there are a number of advanced reactor designers developing smaller sized reactors than those traditionally used in the nuclear power industry, most of these developers are generally pursuing regulatory approval of groupings of these smaller reactors as part of singular larger plants, including output ranges of 200 MWe and up to 1,000 MWe.

In contrast, we plan to be the designer, builder, owner, and operator of our powerhouses and plan to focus on small-scale powerhouses (15 MWe, 75 MWe, and 100 MWe and higher). As a result, we have an incentive to relentlessly focus on the full lifecycle of a safe, well-maintained, cost-effective powerhouse and holistically implement the benefits of an inherently safe, simple design. We expect this approach to enable us to reduce and manage lifecycle regulatory and operating costs in an integrated fashion, as opposed to the historical model used in the nuclear power industry that divides the incentives and responsibilities between the developer and the utility.

Selling electricity under PPAs follows an established revenue model in global power markets. While this model is more typically used for renewable energy solutions, we believe it is a compelling model for us because of the relatively small size and the lower expected capital costs of our powerhouses, when compared with other nuclear power plants. In addition, our model is designed to generate recurring revenue in a way that the traditional licensing model does not. We expect our powerhouses to be profitable from the first year of operation due to our anticipated favorable unit economics. We also believe this approach will drive unit growth and allow us to ultimately launch higher output versions of our powerhouses. As our technology matures, we intend to offer customers flexibility in business model and deployment solutions to meet their needs, providing Oklo with the largest target customer base possible.

In addition to selling power under PPAs, we believe we have an embedded opportunity to enhance our mission with our advanced nuclear fuel recycling technology. We are actively developing nuclear fuel recycling capabilities with the goal of deploying a commercial-scale fuel recycling facility in the United States by the early 2030s. Used nuclear fuel waste still contains more than 95% of its energy content, and we estimate there is enough energy in the form of used nuclear fuel in the U.S. to power the expected electrical needs in the United States for 100 years with fast fission power plants. According

Table of Contents

to the DOE, more than 94,000 metric tons of used nuclear fuel have been generated since 1950, and an additional 2,000 metric tons are generated every year. Currently, other countries recycle used nuclear fuel waste, but the United States does not, and there is an enormous opportunity to do so. Our reactors are specifically designed to run on either fresh or recycled nuclear fuel, and nuclear fuel recycling could provide future margin uplift for our power sales business, as well as the potential for new revenue streams.

Recent Developments

Atomic Alchemy Acquisition

On February 28, 2025, we acquired all of the common stock outstanding of Atomic Alchemy, Inc. (“Atomic Alchemy”), by way of a statutory merger, to combine Oklo’s expertise in building and operating fast reactors and nuclear fuel recycling with Atomic Alchemy’s expertise in radioisotope production. Together, we aim to meet the increasing demands for radioisotopes in medical, energy, industry, defense and artificial intelligence applications. We paid certain of Atomic Alchemy’s investors cash of approximately $1.0 million and exchanged 820,840 shares of our Class A common stock ("common stock") with a price per share of $33.39 at the acquisition date, representing $27.4 million of stock consideration. In addition, we issued 274,339 shares of our common stock, subject to certain lock-up provisions, vesting conditions and substantial risk of forfeiture, representing postcombination services, pursuant to an employment agreement and vesting agreement.

Key Factors Affecting Our Performance

We believe that our future success and financial performance depend on a number of factors that present significant opportunities for our business, but also pose risks and challenges. As a result, we are subject to continuing risks and uncertainties. For additional information, see the section titled “Risk Factors” in Part II, Item 1A of this Quarterly Report and in Oklo's Annual Report on Form 10-K.

Product Development Plan

We plan to leverage the next-generation fast fission powerhouses that we are developing in order to sell power to a variety of potential customers, including data centers, national defense, factories, industrial customers, off-grid and rural customers and utilities.

Commercial deployment of any advanced fission power plant requires obtaining regulatory approvals for design, construction, and operation. Our regulatory strategy has been focused on a custom combined license application. We submitted an initial custom combined license application with the Nuclear Regulatory Commission (“NRC”) in March 2020, which was denied without prejudice in 2022, and we are working toward submitting an updated custom combined license application for review. In March 2020, we became the first advanced fission company to submit a custom combined license application, and we remain the only such company to do so. It is uncertain when, if at all, we will obtain regulatory approvals for the design, construction, and operation of any of our powerhouses. Our financial condition and results of operation are likely to be materially and adversely affected if we do not obtain such approvals and to the extent this process takes longer or costs more than we expect.

Additionally, we plan to be the designer, builder, owner, and operator of our powerhouses and plan to focus on small-scale powerhouses (15 MWe, 75 MWe, and exploring 100 MWe and higher designs). As a result, we have an incentive to relentlessly focus on the full lifecycle of a safe, well-maintained, cost-effective powerhouse and holistically implement the benefits of an inherently safe, simple design. We expect this approach to enable us to reduce and manage lifecycle regulatory and operating costs in an integrated fashion, as opposed to the historical model used in the nuclear power industry that divides the incentives and responsibilities between the developer and the utility. However, this model exposes us directly to the costs of building, owning, and operating our powerhouses. Our cost projections are heavily dependent upon fuel and raw materials (such as steel), equipment and technical and construction service providers (such as engineering, procurement, and construction firms). The global supply chain, on which we will rely, has been significantly impacted in recent years by inflation, instability in the banking sector, war and other hostilities, and other economic uncertainties, resulting in potential significant delays and cost fluctuations. Similar developments in the future may impact our performance from both a deployment and cost perspective.

Plan of Operations

Table of Contents

To further our target of deploying our first powerhouse in late 2027 or early 2028, during 2025, we will engage or continue to engage in the following key initiatives:

•Progressing regulatory approval with the NRC, including a Pre-Application Readiness Assessment for our next Combined License Application, which has commenced in the first half of 2025.

•Progressing regulatory pre-application related activities with the NRC for licensing of commercial fuel fabrication.

•Continuing work related to fuel recycling, such as pre-application regulatory alignment efforts with the NRC, and research and development, both independently and in conjunction with the DOE, focused on facility and process design.

•Working with INL on fuel manufacturing, including preparation of documentation for regulatory review and finalization of the facility design.

•Continuing regulatory activities for DOE approval for the Aurora fuel fabrication facility.

•Advancing partnerships related to fuel enrichment, fuel fabrication, and other key supply chain elements, as well as other procurement activities to expand our fuel sourcing supply chain.

•Executing on key non-fuel elements of our supply chain including, steam turbine generator sourcing, steel, and other construction inputs.

•Progressing engineering procurement and construction activities in support of the construction of Aurora powerhouses.

•Continuing and initiating site preparation for announced facilities at the INL, and Piketon, Ohio, respectively. We will begin site preparation for other announced projects based on prioritization, potentially including customers such as Equinix, Diamondback Energy, Prometheus Hyperscale, Switch, and other projects yet to be announced but where commercial discussions have been initiated.

•Negotiating and executing additional letters of intent and converting them into power purchase agreements with multiple potential customers.

•Negotiating and trading term sheets and binding power purchase agreements with customers who have previously signed nonbinding agreements such as letters of intent to purchase power.

•Developing and executing plans for our radioisotope business.

•Continuing to hire additional personnel and implement processes and systems necessary to deliver our business strategy.

•Progressing production of radioisotopes by Atomic Alchemy and assessing options to scale production.

For the three months ended March 31, 2025 and the year ended December 31, 2024, our total operating expenses were $17.9 million and $52.8 million, respectively. We expect our total net cash used in operating activities for 2025 to be in the range of $65.0 million to $80.0 million.

Nuclear Energy Industry

The nuclear energy industry operates in a politically sensitive environment, and the successful execution of our business model is dependent upon public support for nuclear power, in general, in the U.S. and other countries. Recently, the U.S. government has indicated through bipartisan action that it recognizes the importance of nuclear power in meeting the United States’ growing energy needs. However, the current political environment in the U.S. could change at any time, including in response to events and circumstances over which we exercise no control and the perception of such events and

circumstances. Additionally, opposition by third parties could delay the licensing that our business model requires. As a result, our performance will depend in part on factors generally affecting the views and policies regulating nuclear energy industry, which we cannot predict over the long term.

Key Components of Results of Operations

Operating Expenses

Our operating expenses consist of research and development and general and administrative expenses.

Research and Development

Research and development (“R&D”) expenses represent costs incurred to develop our technology. These costs consist of personnel costs, including salaries, employee benefit costs, bonuses and stock-based compensation expenses, software costs, computing costs, hardware and experimental supplies, and expenses for outside engineering contractors for analytical work and consulting costs. We expense all R&D costs in the periods in which they are incurred; however, occasionally, the reimbursement would be received in the following period.

We have several recycling technology projects awarded as R&D cost-share projects (the “cost-share projects”) through the Department of Energy’s Advanced Research Projects Agency – Energy (“ARPA-E”) and the DOE Technology Commercialization Fund (“TCF”). The ARPA-E and TCF projects involve cost-sharing of project costs as well as reimbursement of certain qualifying expenditures to us. A budget was initially approved for each of these cost-share projects, and as certain expenses and capital expenditures for equipment are incurred, such expenses or capital expenditures are reported to ARPA-E and then a pre-determined percentage of such expenses or capital expenditures are reimbursed by ARPA-E back to us. The expenses are categorized as R&D expenses, which are then partially reimbursed.

General and Administrative

Our general and administrative (“G&A”) expenses primarily comprise various components not related to R&D, such as personnel costs, regulatory fees, promotion expenses, costs associated with maintaining and filing intellectual property, meals and entertainment expenses, travel expenses, and other expenditures related to external professional services including legal, engineering, marketing, human resources, audit, and accounting services. Personnel costs include salaries, benefits, and stock-based compensation expenses. As we continue to grow and expand our workforce and operations, and in light of the increased costs associated with operating as a public company, we anticipate that our G&A expenses will rise for the foreseeable future.

Other Income (Loss)

Other income (loss) consists of interest and dividend income and the remeasurement losses related to SAFEs.

Income Taxes

Income taxes primarily consist of income taxes in certain jurisdictions in which we conduct business and a reduction in the valuation allowance related to deferred tax liabilities established in connection our acquisition of business. We have a full valuation allowance for deferred tax assets, including net operating loss carryforwards and tax credits related primarily to research and development. Prior to the Recapitalization, income taxes have been minimal. After the Recapitalization, as a result of our interest and dividend income from our investments, federal and state income taxes may be incurred, after available tax deductions, including available carryovers.

Liquidity and Capital Resources

As of March 31, 2025, our cash, cash equivalents and marketable debt securities were $260.7 million. We continue to incur significant operating losses. For the three months ended March 31, 2025, we had a net loss of $9.8 million, loss from operations of $17.9 million, and net cash used in operating activities of $12.2 million. As of March 31, 2025, we had an accumulated deficit of $144.9 million. Management expects that significant on-going operating expenditures will be necessary to successfully implement our business plan and develop our powerhouses and expand our radioisotope business.

Table of Contents

We will utilize our existing cash, cash equivalents and marketable debt securities to fund our powerhouses, operations and growth plans and we believe that our existing cash, cash equivalents and marketable debt securities will be sufficient to fund our operations for the one-year period following the issuance date of the accompanying condensed consolidated financial statements as of and for the three months ended March 31, 2025.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements except for the lease option agreement (further information is provided under the heading Lease Option Agreement in Note 12, Commitments and Contingencies, in our accompanying condensed consolidated financial statements).

Commitments and Contractual Obligations

We do not have any material commitments or contractual obligations, other than with respect to the leases under which we lease real estate for office space. These leases are classified as operating leases and expire on December 1, 2026. See Note 5, Leases, in our accompanying condensed consolidated financial statements for more information regarding our commitments and contractual obligations.

Cash Flows Comparison

A summary of our consolidated sources and uses of cash, cash equivalents, was as follows:


	Three Months Ended March 31,
(in thousands)	2025		2024
Net cash used in operating activities	$	(12,243)	$	(7,287)
Net cash provided by (used in) investing activities	6,064		(97)
Net cash (used in) provided by financing activities	(875)		35,535
Net (decrease) increase in cash and cash equivalents	$	(7,054)	$	28,151
Cash and cash equivalents, end of period	$	90,078	$	38,019

Operating Activities

Cash used in operating activities during the three months ended March 31, 2025 consisted of cash outflows of $15.6 million, offset by $3.4 million of net interest and dividend income, totaling $12.2 million in cash used, as compared to cash outflows of $7.4 million, offset by $0.1 million of interest and dividend income, totaling $7.3 million in cash used in the same period in 2024. This $8.2 million increase in cash outflows, partially offset by $3.4 million of net interest and dividend income, was driven by our operating results (net loss adjusted for noncash adjustments totaling $2.6 million) which resulted in $4.9 million of higher cash used by operating activities period-over-period, as well as a $1.0 million increase in cash used resulting from net changes in current operating assets and liabilities. Cash used in operating activities for the three months ended March 31, 2025 was primarily driven by our operating expenses as we continue to scale our operations, consisting of $6.8 million in cash used for payroll and employee benefits of personnel and $8.8 million in other costs, primarily consisting of professional services for consulting on research and development activities, and legal and accounting fees on general and administrative activities.

Investing Activities

Cash provided by investing activities during the three months ended March 31, 2025 was primarily due to $0.3 million use of cash on the purchase of discretionary property and equipment and $29.9 million use of cash on the purchase of marketable debt securities, cash used for acquisition of business of $0.9 million, partially offset by $37.2 million of proceeds from redemptions of marketable debt securities.

Cash used in investing activities for the three months ended March 31, 2024 was due to the purchase of discretionary property and equipment of $0.1 million.

Financing Activities

Table of Contents

Cash used in financing activities for the three months ended March 31, 2025 consisted of the proceeds from the exercise of stock options of $0.7 million, partially offset by the payment of taxes from common stock withheld of $1.6 million.

Cash provided by financing activities for the three months ended March 31, 2024 consisted of the proceeds from right of first refusal liability of $25.0 million, proceeds from the issuance of SAFEs of $10.2 million, as well as proceeds from the exercise of stock options of $0.4 million, partially offset by payment of deferred issuance costs of $0.1 million.

Results of Operations

The following tables set forth our results of operations for the periods presented. The period-to-period comparison of financial results is not necessarily indicative of future results:

Research and Development

The following table sets forth R&D expenses:


	Three Months Ended March 31,				2025 versus 2024
(in thousands)	2025		2024		$ Change		% Change







Total research and development expenses	$	7,846	$	3,660	$	4,186	114.4	%

R&D expenses increased by $4.2 million, or 114.4% for the three months ended March 31, 2025, compared to the same period in 2024. The increase was primarily due to an increase of $1.7 million in total payroll and employee benefits of research and development personnel attributable to an increase in the headcount of R&D personnel of approximately 61.4% and an increase in salary over the prior period, an increase of $0.6 million in stock-based compensation expenses, an increase of $0.9 million in professional services, and an increase of $1.0 million in other expenses.

General and Administrative

The following table sets forth G&A expenses:


	Three Months Ended March 31,				2025 versus 2024
(in thousands)	2025		2024		$ Change		% Change








Total general and administrative expenses	$	10,028	$	3,710	$	6,318	170.3	%

G&A expenses increased by $6.3 million, or 170.3% for three months ended March 31, 2025, compared to the same period in 2024. The increase was primarily due to an increase of $2.0 million in payroll and employee benefits of general corporate personnel attributable to an increase in the headcount of G&A personnel of approximately 57.1% and average salary over the prior period, an increase of $1.1 million in stock-based compensation expenses, an increase of $1.5 million

Table of Contents

in professional services primarily due to an increase in legal and other professional fees, and an increase of $1.7 million related to travel, entertainment, and other expenses.

Other Income (Loss)

The following table sets forth other income (loss):


	Three Months Ended March 31,				2025 versus 2024
(in thousands)	2025		2024		$ Change		% Change
Change in fair value of SAFEs	$	—	$	(16,793)	$	16,793	NM
Interest and dividend income	3,653		141		3,512		NM
Total other loss	$	3,653	$	(16,652)	$	20,305	(121.9	%)

The change in fair value of SAFEs was a result of the SAFEs being converted into common stock upon the completion of the Recapitalization on May 9, 2024 where all SAFE's were converted and none were outstanding as of the end of the reporting period. Interest and dividend income increased by $3.5 million for the three months ended March 31, 2025, compared to the same period in 2024. The increase was primarily due to an increase in interest and dividend income related to an increase in our cash, cash equivalents and marketable debt securities balances from the prior year period.

Income Taxes

For the three months ended March 31, 2025, we recorded a deferred income tax benefit of 4.7 million related to acquired deferred tax liabilities in connection with our acquisition during the period and change in valuation allowance as of period-end that was offset by current income tax expense.

Critical Accounting Estimates

Part II, Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operation in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 provides a more complete discussion of our critical accounting policies and estimates, together with the following additional critical accounting estimate:

Determination of fair value for the acquisition of a business

The determination of fair value for the acquisition of a business in business combination requires the allocation of the purchase price to the various assets acquired and liabilities assumed at their respective fair values. The determination of fair value requires the use of significant estimates and assumptions, and in making these determinations, management uses all available information. If necessary, we have up to one year after the acquisition closing date to finalize these fair value determinations under the applicable U.S. GAAP. For tangible and identifiable intangible assets acquired in a business combination, the determination of fair value utilizes several valuation methodologies including discounted cash flows which has assumptions with respect to the timing and amount of future revenue and expenses associated with an asset. The assumptions made in performing these valuations include, but are not limited to, discount rates, future revenues and operating costs, projections of capital costs, and other assumptions believed to be consistent with those used by principal market participants. Due to the specialized nature of these calculations, we engage third-party specialists to assist management in evaluating our assumptions as well as appropriately measuring the fair value of assets acquired and liabilities assumed.

Emerging Growth Company Status

The Company is classified as an emerging growth company (“EGC”), as defined under the Jumpstart Our Business Startups Act (the “JOBS Act”). Therefore, we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not EGCs. We could retain EGC status until December 31, 2026, although circumstances could cause us to lose that status earlier, including if the market value of common stock held by non-affiliates exceeds $700,000,000 as of any June 30 before that time, in which case we would no longer qualify for EGC status as of the following December 31.

Table of Contents

Further, Section 102(b)(1) of the JOBS Act exempts EGCs from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-EGCs, but any such election to opt out is irrevocable. We intend to take advantage of the benefits of this extended transition period.

Recent Accounting Pronouncements

There has been no adoption of any new accounting pronouncements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Not applicable to a “smaller reporting company” as defined in Item 10(f)(1) of SEC Regulation S-K.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management is responsible for establishing and maintaining a system of disclosure controls and procedures (as defined in Rule13a-15(e) and 15d-15(e) under the Exchange Act) that is designed to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized, and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by an issuer in the reports that it files or submits under the Exchange Act is accumulated and communicated to the issuer’s management, including its principal executive officer(s) and principal financial officer(s), or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

In accordance with Exchange Act Rules 13a-15 and 15d-15, an evaluation was completed under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report. Our management, including our Chief Executive Officer and Chief Financial Officer, concluded that our disclosure controls and procedures were not effective as of March 31, 2025 in providing reasonable assurance that the information required to be disclosed in our reports filed or submitted under the Exchange Act was recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms.

Previously Reported Material Weakness

As disclosed in Item 9A, “Controls and Procedures” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, which was filed with the SEC on March 24, 2025, a material weakness related to infrequent and complex transactions was identified as of December 31, 2024.

After giving full consideration to this material weakness, and the additional analyses and other procedures we performed to ensure that our unaudited condensed consolidated financial statements included in this Quarterly Report on Form 10-Q were prepared in accordance with U.S. GAAP, our management has concluded that our condensed consolidated financial statements present fairly, in all material respects, our financial position, results of operations and cash flows for the periods disclosed in conformity with U.S. GAAP.

We intend to undertake the following remediation measures to address the material weakness described above:

•Improve processes where management reviews information provided by third parties; and

•Implement additional controls where finance and accounting reviews any amendments to third party agreements, as supported through hiring or use of third-party consultants and specialists, to ensure appropriate accounting treatment.

We expect that the remediation of this matter that was deemed a material weakness will be fully complete no later than December 31, 2025.

Changes in Internal Control over Financial Reporting

In connection with our continued monitoring and maintenance of our control procedures as part of the implementation of Section 404 of the Sarbanes-Oxley Act of 2002, as amended, we continue to review, test, and improve the effectiveness of our internal controls. There have not been any changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the three months ended March 31, 2025, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on the Effectiveness of Controls

The effectiveness of any system of internal control over financial reporting, including ours, is subject to inherent limitations, including the exercise of judgment in designing, implementing, operating, and evaluating the controls and procedures, and the inability to eliminate misconduct completely. Accordingly, in designing and evaluating the disclosure controls and procedures, management recognizes that any system of internal control over financial reporting, including ours, no matter how well designed and operated, can only provide reasonable, not absolute assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints, and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. We intend to continue to monitor and upgrade our internal controls as necessary or appropriate for our business but cannot assure you that such improvements will be sufficient to provide us with effective internal control over financial reporting.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, we may be subject to claims and litigation arising in the ordinary course of business. We are not currently subject to any pending or threatened legal proceedings that we believe would reasonably be expected to have a material adverse effect on our business, financial condition, results of operations or cash flows.

Item 1A. Risk Factors

There are numerous factors that affect our business and operating results, many of which are beyond our control. Except as provided below, there are no material changes to the risk factors previously disclosed under the “Risk Factors” section in Oklo's Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

Changes to trade policies, including higher tariffs, restrictions and other economic disincentives to trade, may lead to operational delays, higher procurement and operational costs, and regulatory and compliance complexities, resulting in supply chain disruptions and higher prices and lower demand for devices and services we sell.

We depend on suppliers to provide us, directly or through other suppliers, with items such as equipment for [the development of our reactors], other components and raw materials. Changes or proposed changes in U.S. or other countries’ trade policies that result in higher tariffs, restrictions and other economic disincentives to international trade may materially increase the costs we incur in developing, deploying and maintaining our [reactors]. A certain portion of the increased costs may be absorbed by certain suppliers, but some suppliers may struggle to absorb the increased costs, especially over the long term, potentially leading to supply disruptions or cost pass-throughs to us, which may lead to [an increase in our expenditures]. In addition, rapid changes in trade policies may negatively affect procurement timelines and supplier relationships and may introduce new compliance requirements. We may face potential delays in sourcing critical equipment due to customs clearance and supply chain bottlenecks, and material changes to cost structures could pressure our expenses and customer pricing.

Our attempts to mitigate potential disruptions to our supply chain and offset procurement and operational cost pressures, such as through alternative sourcing and/or increases in the selling prices of some of our products, may not be successful. Higher prices for our customers may make it more difficult to attract new customers or cause increases in customer churn. Furthermore, we may not be able to offset any cost increases through productivity and cost-saving initiatives. To the extent that cost increases result in significant increases in our expenditures, or if our price increases are not sufficient to offset these increased costs adequately or in a timely manner, and/or if our revenues decrease, our business, financial condition or operating results may be adversely affected.
