Oklo Inc. (NYSE: OKLO) filed its Form 10-Q for the quarterly period ended March 31, 2026, offering a comprehensive look at the advanced nuclear fission company's progress as it continues to develop its Aurora fission powerhouses, fuel recycling capabilities, and radioisotope business. The filing reveals a company in a significant growth and investment phase — scaling its workforce, advancing multiple regulatory and commercial milestones, and substantially strengthening its balance sheet through a $1.18 billion at-the-market equity offering — all while remaining in a pre-revenue stage and reporting a net loss of $33.1 million for the quarter. With $2.54 billion in total liquidity, a target of deploying its first commercial powerhouse in 2028, and major customer commitments including agreements with Meta Platforms and Switch, Oklo is positioning itself at the forefront of the next wave of nuclear energy deployment.

I. Business Developments and Strategic Initiatives

Oklo Inc. continued to make substantial progress across its reactor design, licensing, and deployment activities during the first quarter of 2026. The Company achieved several significant regulatory milestones for its first Aurora powerhouse at Idaho National Laboratory (INL). Early in 2026, the U.S. Department of Energy (DOE) approved the Nuclear Safety Design Agreement for the Aurora-INL project, and the DOE and INL completed the environmental compliance process, resulting in an Environmental Compliance Permit. Oklo also secured a site use permit from the DOE for the INL site and received a fuel award of five metric tons of HALEU produced from recovered uranium from previously irradiated EBR-II fuel [Item 2 - MD&A, ¶4]. The Company is targeting deployment of its first commercial powerhouse in 2028 [Item 2 - MD&A, ¶6].

On the commercial front, Oklo significantly expanded its customer partnerships and site selection activities. On January 5, 2026, the Company entered into a prepayment agreement with Meta Platforms, Inc. to advance plans for a 1.2 gigawatt power campus in Pike County, Ohio, to support Meta's data centers. Additionally, Oklo has signed non-binding letters of intent with Equinix, Diamondback Energy, and Prometheus Hyperscale, and in December 2024 signed a 12-gigawatt Master Power Agreement with Switch, one of the largest corporate power purchase agreements in history. The Company has also been tentatively selected to provide electricity and heat to Eielson Air Force Base in Alaska [Item 2 - MD&A, ¶5]. Oklo is exploring opportunities with the Tennessee Valley Authority to recycle used fuel and evaluate potential power sales in the region, and has selected Kiewit Nuclear Solutions as the lead constructor for its first Aurora powerhouse in Idaho [Item 2 - MD&A, ¶27].

In fuel recycling and fabrication, Oklo achieved multiple key milestones. The Company's Aurora Fuel Fabrication Facility at INL was selected under the DOE Fuel Line Pilot Program, which allows for acceleration of permitting, construction, and operation. Oklo also successfully completed the first end-to-end demonstration of key stages of its advanced fuel recycling process in collaboration with Argonne National Laboratory and INL. In September 2025, the Company announced plans to design, build, and operate a fuel recycling facility in Tennessee as the first phase of an Advanced Fuel Center, representing up to $1.68 billion in potential investment and an estimated 800 high-quality jobs [Item 2 - MD&A, ¶7].

Oklo has also been advancing a diversified fuel strategy. In December 2025, the Company completed a fast-spectrum plutonium criticality experiment in collaboration with Los Alamos National Laboratory, collecting operating data related to reactivity feedback and power response — empirical validation that places Oklo among a limited number of organizations with modern validated data for plutonium-fueled fast-spectrum reactor systems. The Company has completed a licensing project plan for its fuel recycling facility with the NRC and is currently in pre-application engagement with the regulator's staff [Item 2 - MD&A, ¶8].

On the isotope business front, Oklo announced the execution of a DOE Other Transaction Agreement on January 7, 2026, to support the design, construction, and operation of a Radioisotope Pilot Facility under the DOE's Reactor Pilot Program. On March 17, 2026, the DOE approved the Nuclear Safety Design Agreement for the Groves Isotopes Test Reactor at that facility, allowing it to move into the next phase of project execution. Additionally, Oklo's isotope business received a materials license from the NRC authorizing its Idaho radiochemistry laboratory to handle, process, and distribute isotopes [Item 2 - MD&A, ¶10-11].

On the regulatory front, Oklo completed a Phase I pre-application readiness assessment with the NRC in July 2025 to evaluate the maturity of its siting and environmental approach. The assessment concluded with no significant gaps identified that would hinder acceptance of a combined license application. Separately, in August 2025, the NRC accepted for review Oklo's Principal Design Criteria topical report under an accelerated timeline with an expedited review schedule. Additionally, on August 13, 2025, Oklo and its subsidiary Atomic Alchemy were selected by the DOE for three of eleven projects awarded under the newly established Reactor Pilot Program, with the Aurora-INL powerhouse approved to proceed under the DOE authorization pathway — a framework that provides full authority to construct and operate while maintaining high safety standards [Item 2 - MD&A, ¶22-23].

II. Financial Performance and Results of Operations

Oklo Inc. reported its financial results for the three months ended March 31, 2026, reflecting the company's continued pre-revenue stage as it advances development of its Aurora fission powerhouses, fuel recycling capabilities, and radioisotope business. For the quarter, Oklo recorded a net loss of $33.1 million, compared to a net loss of $9.8 million in the same period of 2025. Basic and diluted loss per share was $(0.19) for the first quarter of 2026, compared to $(0.07) in the prior-year period, with weighted-average shares outstanding increasing to approximately 170.3 million from 138.1 million [Item 1 - Financial Statements, Table 2].

Total operating expenses rose sharply to $51.2 million in Q1 2026, up from $17.9 million in Q1 2025. Research and development (R&D) expenses increased by $19.2 million to $27.0 million, driven primarily by a $5.8 million increase in employee compensation costs reflecting an increase of approximately 85 employees, a $6.5 million increase in stock-based compensation, and a $5.8 million increase in professional services from third-party engineering and consulting providers [Item 2 - MD&A, ¶33]. General and administrative (G&A) expenses increased by $14.2 million to $24.2 million, driven by a $3.4 million increase in employee compensation from approximately 51 additional employees, a $6.8 million increase in stock-based compensation, and a $3.0 million increase in professional services for accounting and consulting [Item 2 - MD&A, ¶34].

Other income, consisting primarily of interest and dividend income on the company's investment portfolio, surged to $21.3 million from $3.7 million, driven by higher cash and marketable securities balances resulting from equity issuances [Item 2 - MD&A, ¶35]. This other income partially offset the significant operating losses, though the company's net loss still widened substantially year-over-year as the organization scaled its operations.

On the balance sheet, Oklo maintained a strong liquidity position. As of March 31, 2026, cash, cash equivalents, and marketable debt securities totaled $2,536.9 million, compared to $1,412.5 million as of December 31, 2025. Total current assets were $2,225.7 million against current liabilities of $37.1 million, resulting in substantial working capital of approximately $2.19 billion. Total stockholders' equity stood at $2,638.6 million, up from $1,476.2 million at year-end 2025, while the accumulated deficit reached $273.8 million [Item 1 - Financial Statements, Table 1] [Item 2 - MD&A, ¶35] [Item 1 - Financial Statements, ¶3].

Oklo did not report any non-GAAP financial measures in its first quarter 2026 filing. The company's financial statements are prepared in accordance with U.S. GAAP, and management evaluates performance using net loss as the primary metric for resource allocation and budgeting.

III. Liquidity, Capital Resources, and Cash Flows

As of March 31, 2026, Oklo Inc. held $1,594.1 million in cash and cash equivalents along with $942.8 million in marketable debt securities, for a total liquidity position of approximately $2.54 billion. This represents a substantial increase from $788.4 million in cash at December 31, 2025, reflecting significant capital-raising activity during the first quarter [Item 2 - MD&A, ¶35].

For the three months ended March 31, 2026, Oklo used $17.9 million in operating activities, compared to $12.2 million in the prior-year period. The increase was driven by higher operating expenses as the company scaled its workforce and professional services, partially offset by $21.2 million in higher cash interest and dividend income from the company's enlarged investment portfolio [Item 2 - MD&A, ¶36].

Net cash used in investing activities was $359.0 million, a significant swing from $6.1 million provided in the prior-year period. This was primarily attributable to net purchases of marketable debt securities totaling $321.2 million, capital expenditures of $32.8 million related to deployment of planned facilities, and $5.0 million in other investments [Item 2 - MD&A, ¶37].

Net cash provided by financing activities totaled $1,182.6 million, compared to $0.9 million used in the prior year, almost entirely driven by proceeds from the company's at-the-market (ATM) equity offering program [Item 2 - MD&A, ¶37]. During the three months ended March 31, 2026, Oklo completed its 2025 ATM Program, issuing approximately 12.4 million shares of common stock at an average net price of $96.95 per share, generating net proceeds of $1,181.9 million. The company also received $0.7 million from stock option exercises during the period. No debt financing activities were reported during the quarter [Item 1 - Financial Statements, ¶24].

Management believes that existing cash, cash equivalents, and marketable debt securities will be sufficient to fund operations for at least the one-year period following the issuance date of the financial statements. The company expects total cash used in operating expenses for full-year 2026 to be in the range of $80 million to $100 million, and total cash used in investing activities to be in the range of $350 million to $450 million [Item 2 - MD&A, ¶29]. These funds are expected to support construction of powerhouses, fuel and radioisotope businesses, and growth plans.

Oklo continues to incur significant operating losses, reporting a net loss of $33.1 million for the quarter and an accumulated deficit of $273.8 million as of March 31, 2026 [Item 2 - MD&A, ¶35]. The company is subject to risks and uncertainties including supply chain constraints, construction and design complexities, inflation, trade policy, and geopolitical factors that could affect future financial condition [Item 1 - Financial Statements, ¶7]. However, management has not identified any going concern uncertainties and explicitly states that existing resources are sufficient for the next twelve months. The company's strong cash position, bolstered by the $1.18 billion in ATM proceeds, provides substantial runway as it works toward its target of deploying its first Aurora powerhouse in 2028.

IV. Risk Factors

Oklo Inc. faces a complex set of risks spanning technology development, regulatory approval, commercialization timelines, capital requirements, and market adoption. As disclosed in the filing, there are no material changes to the risk factors previously reported in Oklo's Annual Report on Form 10-K for the fiscal year ended December 31, 2025 [Item 1A - Risk Factors, ¶1]. However, the company's Management's Discussion and Analysis provides substantial context on the evolving risk landscape facing the business.

Technology and Commercialization Timeline Risks

Oklo's business model depends on the successful deployment of its first Aurora powerhouse, targeted for 2028, amidst a range of supply chain, construction, macroeconomic, and design complexities [Item 2 - MD&A, ¶6]. The company's initial assets will represent the first deployment of the Aurora design and are subject to risks around both cost and time associated with first-of-a-kind capital project delivery, with the first powerhouse at INL expected to include additional, unique costs due to enhanced fuel and core testing capabilities that increase the possibility of construction delays [Item 2 - MD&A, ¶25].

Regulatory Environment Risks

Regulatory approval remains a critical uncertainty. Oklo's long-term regulatory strategy has focused on a custom combined license application with the NRC, and it is uncertain when, if at all, the company will obtain NRC approvals for the design, construction, and operation of any of its powerhouses. The company's financial condition, commercial plans, and results of operations are likely to be materially and adversely affected if such approvals are not obtained or if the process takes significantly longer or costs more than expected [Item 2 - MD&A, ¶22]. While the DOE authorization pathway provides an alternative regulatory framework for the Aurora-INL powerhouse, the company must navigate multiple regulatory regimes simultaneously, and opponents of advanced nuclear deployment could delay the licensing that the business model requires.

Capital Needs and Financial Risks

Oklo continues to incur significant operating losses. As of March 31, 2026, the company had an accumulated deficit of $273.8 million, with a net loss of $33.1 million for the three months ended March 31, 2026. Management expects that significant ongoing operating expenditures will be necessary to implement the business plan, develop powerhouses and fuel recycling facilities, and expand the radioisotope business [Item 2 - MD&A, ¶35]. The company expects total cash used in operating expenses for 2026 to be in the range of $80 million to $100 million and total cash used in investing activities to be in the range of $350 million to $450 million [Item 2 - MD&A, ¶29]. While the company held $2.54 billion in cash, cash equivalents, and marketable debt securities as of March 31, 2026, the substantial capital requirements for deploying first-of-a-kind nuclear assets and building fuel recycling infrastructure represent a significant ongoing funding need.

Fuel Supply and Cost Risks

Fuel is a significant input for Oklo's powerhouses, and the cost environment for various fuel sources, including HALEU, has increased significantly in recent years. Tariffs, supply chain constraints, inflation, and evolving sanctions have impacted market dynamics around fuel costs and availability [Item 2 - MD&A, ¶9]. The company is pursuing a diversified fuel strategy, including evaluating alternative fuel materials such as plutonium, but any such use would be subject to DOE authorization and applicable regulatory approvals, introducing additional uncertainty.

Market Adoption and Competition Risks

Oklo's build-own-operate business model exposes the company directly to the costs of building, owning, and operating its powerhouses, with cost projections heavily dependent on fuel, raw materials, equipment, and technical service providers. The global supply chain has been significantly impacted by inflation, instability, and other economic uncertainties, resulting in potential significant delays and cost fluctuations [Item 2 - MD&A, ¶24]. Additionally, the nuclear energy industry operates in a politically sensitive environment, and the company's performance depends on public support for nuclear power and the outcome of regulatory proceedings. While Oklo has secured significant customer commitments including a 12 GW Master Power Agreement with Switch and a prepayment agreement with Meta, converting non-binding letters of intent into binding power purchase agreements remains a key execution risk that will determine the company's long-term revenue trajectory.

V. Legal Proceedings and Contingencies

As of the quarter ended March 31, 2026, Oklo Inc. reports that it is not currently a party to any pending or threatened legal proceedings that management believes would reasonably be expected to have a material adverse effect on the company's business, financial condition, results of operations, or cash flows [Item 1 - Legal, ¶1]. The company acknowledges that from time to time it may be subject to claims and litigation arising in the ordinary course of business, but no such matters have risen to a level requiring disclosure as material contingencies [Item 1 - Financial Statements, ¶29].

In its Commitments and Contingencies footnote, Oklo further confirms that it is not a party to any legal proceedings and is not aware of any material pending or threatened litigation. The company also states that there were no contingent liabilities recorded as of March 31, 2026 [Item 1 - Financial Statements, ¶29]. Contracts entered into in the normal course of business with third-party service providers and vendors are generally cancellable upon notice and are therefore not considered contractual obligations or commitments requiring disclosure.

With respect to regulatory and tax-related contingencies, Oklo maintains a valuation allowance against substantially all of its deferred tax assets due to cumulative historical operating losses and uncertainty regarding the generation of future taxable income. As of March 31, 2026, the company had unrecognized tax benefits related to federal research credit carryforwards, though full recognition of these benefits would have no impact on the effective tax rate and would result in a corresponding adjustment to the valuation allowance [Item 1 - Financial Statements, ¶28]. No interest or penalties related to these unrecognized tax benefits have been accrued.

The company's risk factor disclosures incorporate by reference the risk factors previously disclosed in its Annual Report on Form 10-K for the fiscal year ended December 31, 2025, with no material changes identified during the current period [Item 1A - Risk Factors, ¶1]. These risk factors include the broader uncertainties inherent in Oklo's business, such as supply chain complexities, construction and design challenges, macroeconomic conditions, and regulatory dynamics that could give rise to future claims or contingencies [Item 1 - Financial Statements, ¶7].

From a financial position standpoint, Oklo held $2.5 billion in cash, cash equivalents, and marketable debt securities as of March 31, 2026, though the company continues to incur significant operating losses, reporting a net loss of $33.1 million for the three-month period and an accumulated deficit of $273.8 million [Item 1 - Financial Statements, ¶3]. The company believes its existing liquidity is sufficient to fund operations for at least the next twelve months. The absence of material pending litigation or recorded contingent liabilities, combined with a strong cash position, suggests that legal contingencies do not currently pose a material financial risk to Oklo's operations or financial condition. However, as the company continues to develop its advanced fission power plants, fuel recycling capabilities, and radioisotope production facilities, the potential for future regulatory proceedings, contractual disputes, or other legal matters remains an ongoing consideration for management.

Conclusion

Oklo Inc.'s first quarter 2026 10-Q paints a picture of a company executing aggressively on its vision for advanced nuclear energy deployment. With $2.54 billion in liquidity following a highly successful $1.18 billion ATM equity offering, a growing roster of marquee customers including Meta and Switch, and significant regulatory and technical milestones achieved across its reactor design, fuel recycling, and radioisotope businesses, Oklo is laying substantial groundwork for its targeted first commercial powerhouse deployment in 2028. The widening net loss of $33.1 million reflects the natural cost of scaling a pre-revenue deep-tech enterprise — investing in workforce expansion, engineering, and facility construction — but the company's robust cash position provides meaningful runway to navigate the complex regulatory, technical, and commercial path ahead. As Oklo continues to convert its non-binding customer commitments into binding agreements and advance through the NRC and DOE regulatory processes, the coming quarters will be critical in determining whether the company can translate its ambitious strategic initiatives into operational reality.
