As filed, 34,123 characters.

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations, or MD&A, is intended to help the reader understand Lightbridge Corporation, our operations, and our present business environment. MD&A is provided as a supplement to, and should be read in conjunction with, our unaudited condensed consolidated financial statements and the accompanying notes thereto contained in Part I, Item 1 of this report, as well as those included in our Annual Report on Form 10-K for the year ended December 31, 2024.

This MD&A consists of the following sections:

- Overview of Our Business and Recent Developments of Lightbridge Fuel™ - a general overview of our business and updates;
- Critical Accounting Estimates;
- Operations Review - an analysis of our condensed consolidated results of operations for the periods presented in our condensed consolidated financial statements; and
- Liquidity, Capital Resources, and Financial Position - an analysis of our cash flows and an overview of our financial position.

As discussed in more detail under “Forward-Looking Statements” preceding this MD&A, the following discussion contains forward-looking statements that are based on our management’s current expectations, estimates, and projections, which are subject to a number of risks and uncertainties. Our actual results may differ materially from those discussed in these forward-looking statements because of the risks and uncertainties inherent in future event*s,* including those set forth under “Forward-Looking Statements” and Part II. Item 1A. Risk Factors included herein.

### OVERVIEW OF OUR BUSINESS AND DEVELOPMENT OF LIGHTBRIDGE FUELTM

When used in this Quarterly Report on Form 10-Q, the terms “Lightbridge,” the “Company,” “we,” “our,” and “us” refer to Lightbridge Corporation together with its wholly-owned subsidiaries Lightbridge International Holding LLC and Thorium Power Inc. Lightbridge’s principal executive offices are located at 11710 Plaza America Drive, Suite 2000, Reston, Virginia, 20190, USA.

### Our Business

At Lightbridge, we are developing next generation nuclear fuel for water-cooled reactors that could significantly improve the economics and safety of existing and new nuclear power plants, large and small, and enhance proliferation resistance of spent nuclear fuel while supplying clean energy to the electric grid or to “behind the meter” customers for electric power, including data centers. We believe that the world’s energy and climate needs can only be met if nuclear power’s share of the energy-generating mix grows substantially in the coming decades. We believe Lightbridge can benefit from a growing nuclear power industry, and that our nuclear fuel can help enable that growth to happen.

We believe our metallic fuel will offer significant economic and safety benefits over traditional nuclear fuel, primarily because of the superior heat transfer properties and the resulting lower operating temperature of all-metal fuel.

Technology industry companies believe that nuclear energy can offer a strategic, sustainable, and reliable solution for powering data centers. Advances in reactor technology, combined with growing corporate and governmental support for clean energy, can position nuclear power as a cornerstone of future energy strategies for data-intensive industries. We believe that by integrating nuclear power, the data center sector can achieve operational efficiency, energy security, and sustainability. We believe uses of our fuel could include providing additional power via power uprates of existing reactors, which may be willing to pay a premium for reliable, clean, and sustainable baseload electricity. Oil and gas producing companies are investing in low-emission energy technologies to reduce fossil fuel emissions from oil and gas production. Advances in nuclear reactor and fuel technology can position nuclear power as a key energy source for this purpose.

Emerging nuclear technologies include small modular reactors (SMRs), which are now in the development and licensing phases. We expect that Lightbridge Fuel™ can provide water-cooled SMRs with the same benefits our technology brings to large reactors, with such benefits being even more meaningful to the economic case for deployment of SMRs, including potential load following capability when included on a virtually zero-carbon electric grid with renewable energy sources. We expect Lightbridge Fuel™ to enable power uprates in SMRs.

We have built a significant portfolio of patents, and we anticipate testing our nuclear fuel through third-party vendors and others, including the United States Department of Energy’s (DOE) national laboratories. Currently, we are performing the majority of our R&D activities within and in collaboration with the DOE’s national laboratories.

### Recent Developments of Lightbridge Fuel™

#### Memorandum of Understanding with Oklo, Inc.

In January 2025, we signed a memorandum of understanding (MOU) with Oklo, Inc. Oklo is developing advanced micro-reactors to provide clean, reliable, and affordable energy at scale. The scope of the MOU includes the following areas: (1) to conduct a preliminary evaluation of feasibility of co-locating a Lightbridge Commercial-scale Fuel Fabrication Facility at Oklo’s proposed commercial fuel fabrication facility, (2) to explore opportunities for collaboration on reprocessing and recycling of spent uranium zirconium fuel, and (3) to explore any other areas of collaboration that may be of mutual interest. We believe there may be some potential synergies in co-locating our commercial scale fuel fabrication facility at Oklo’s proposed site. We also believe recycling and reprocessing spent uranium-zirconium fuel represents another area of potential synergies.

#### Idaho National Laboratory Agreements

In December 2022, Lightbridge entered into agreements with Battelle Energy Alliance, LLC (BEA), the DOE’s operating contractor for Idaho National Laboratory (INL), to support the development of Lightbridge Fuel™. The framework agreements use an innovative structure that consists of an “umbrella” Strategic Partnership Project Agreement (SPPA) and an “umbrella” Cooperative Research and Development Agreement (CRADA), each with BEA, with an initial duration of seven years.

We anticipate that the initial phase of work under the two agreements that has been released will culminate in casting and extrusion of unclad fuel material samples using enriched uranium supplied by the DOE that will subsequently be inserted for irradiation testing in the Advanced Test Reactor (ATR) at INL. The initial phase of work aims to generate irradiation performance data for Lightbridge’s delta-phase uranium-zirconium alloy relating to various thermophysical properties. The data will support fuel performance modeling and regulatory licensing efforts for commercial deployment of Lightbridge Fuel™. We use a rolling wave planning approach for project management purposes on the released scopes of work. It is an iterative planning technique in which the work to be accomplished in the near term is planned in detail, while work further in the future is planned at a higher level. As such, periodic revisions to the scope and/or cost estimates are anticipated.

On March 26, 2024 and October 24, 2024, the Company and BEA entered into Modifications No. 2 and No. 3 respectively, to PTS No. 1 under the SPPA, dated December 9, 2022, as amended on May 23, 2023, by and between the Company and BEA. Pursuant to the terms of Modifications No. 2 and No. 3, the potential amounts payable by the Company to reimburse BEA for its expenses and employee time were increased by approximately $0.6 million and $0.3 million, respectively, bringing the total estimated cost for the work to be performed under the “umbrella” SPPA to approximately $2.0 million.

On March 18, 2025, the Company and BEA entered into Modification No. 4 to the PTS No. 1 under the SPPA, dated December 9, 2022, as amended on May 23, 2023, March 26, 2024 and October 24, 2024, by and between the Company and BEA. Pursuant to the terms of Modification No. 4, the potential amounts payable by the Company to reimburse BEA for its expenses and employee time were increased by approximately $0.6 million, bringing the total estimated cost for the work to be performed under the “umbrella” SPPA to $2.6 million.

On January 16, 2025 the Company and BEA entered into Modification No. 3 to PTS No. 1 under the CRADA, dated September 27, 2022, as amended on May 22, 2023, May 30, 2023, by and between the Company and BEA. Pursuant to the terms of Modification No. 3, the potential amounts payable by the Company to reimburse BEA for its expenses and employee time were increased from $2.6 million by approximately $1.6 million, bringing the total estimated cost for the work to be performed under the “umbrella” CRADA to $4.2 million. This modification also required that a $0.6 million advance payment be made, which was paid on January 16, 2025.

After accounting for all modifications, cash payments from Lightbridge to Battelle under both CRADA and SPPA are estimated at approximately $6.8 million on a cost reimbursable basis over the performance periods.

The Company anticipates entering into additional modifications to the Project Task Statements (PTS) under the SPPA and/or CRADA with INL to expand the scope of work, including performing additional extrusions, updating the experiment design for irradiation testing of coupon samples in the ATR, and other potential activities. The successful execution of this project is subject to risks, including potential delays, cost overruns, regulatory challenges, and changes in funding availability, and if the project scope does increase, then the project will be successfully executed or completed. Regardless of whether further project modifications occur, INL has indicated to the Company that due to resource and manufacturing equipment constraints, INL may not be able to meet the Company’s preferred project timeline, and that the total project cost will exceed the current budget.

We anticipate that subsequent phases of work under the two umbrella agreements that have not yet been released may include post-irradiation examination of the irradiated fuel material coupons, loop irradiation testing in the ATR, and post-irradiation examination of one or more uranium-zirconium fuel rodlets, as well as transient experiments in the Transient Reactor Test Facility at INL.

#### Romania Feasibility Study of Lightbridge Fuel™ for use in CANDU reactors

On October 16, 2023, we engaged Institutul de Cercetări Nucleare Pitești, a subsidiary of Regia Autonoma Tehnologii pentru Energia Nucleara (RATEN ICN) in Romania to perform an engineering study to assess the compatibility and suitability of Lightbridge Fuel™ for use in CANDU reactors. This assessment covers key areas including mechanical design, neutronics analysis, and thermal and thermal-hydraulic evaluations. The findings from this engineering study will play an important role in guiding future economic evaluations and navigating potential regulatory licensing-related issues for potential use of Lightbridge Fuel™ in CANDU reactors.

The results of this Feasibility Study indicated that Lightbridge Fuel™ can double the discharged burnup in a CANDU reactor at U-235 enrichment levels of less than 3% compared to conventional uranium dioxide fuel. Based on these favorable initial results, we plan to continue further evaluation of Lightbridge Fuel™ in CANDU reactors.

#### Nuclear Energy University Program Awards

Texas A&M University (TAMU), NuScale Power, and Structural Integrity Associates are working on a 3-year study of our nuclear fuel, led by TAMU. The TAMU study is expected to be completed in 2026. In mid-2023, TAMU was awarded $1.0 million by the DOE’s Nuclear Energy University Program (NEUP) R&D Awards to conduct this study. The project entails a characterization of the performance of the Lightbridge Fuel™ Helical Cruciform advanced fuel design, which will generate sets of experimental data on friction factor, flow, and heat transfer behavior under NuScale’s SMR simulated normal and off-normal conditions.

We previously announced the ongoing NEUP project with the Massachusetts Institute of Technology (MIT). The study led by MIT and funded by DOE relates to evaluation of accident tolerant fuels (ATFs) in various SMRs. The project aims to simulate the fuel and safety performance of Lightbridge Fuel™ for the NuScale SMR and provide scoping analysis to improve the safety and economics of water-cooled SMRs. In October 2024, MIT presented a technical paper with preliminary safety evaluation results at the TopFuel 2024 Conference in Grenoble, France. According to MIT, the results have shown promising safety and performance benefits for Lightbridge Fuel™. Compared to conventional fuel, Lightbridge Fuel™ demonstrated improved thermal-hydraulic margins, lower operating temperatures, and greater potential for power uprates, which contributes to enhancing reactor economics.

We do not have any performance obligations with the collaboration teams working on the above-mentioned projects and will not receive any revenue or record any economic benefits from these awards.

### Future Steps Toward Our Fuel Development and Timeline For The Commercialization of Our Nuclear Fuel Assemblies

We anticipate fuel development milestones for Lightbridge Fuel™ over the next 2-3 years will consist of the following:

- **INL:** To produce samples, coupons, and rodlets necessary for testing to be performed under our INL agreements. We will continue to execute the SPPA/CRADA work at INL leading to casting and extrusion of fuel material samples using enriched uranium and their subsequent insertion for irradiation testing in the ATR.
- **Modeling:** Continue development and/or validation (benchmarking) of Lightbridge-specific methods and modifications to existing modeling codes to accurately predict Lightbridge Fuel™ performance over the full domain of operating conditions for which Lightbridge Fuel™ will be licensed.
- **Fuel Qualification Plan:** Develop a Fuel Qualification Plan that describes our approach to characterizing and validating the performance our fuel rods, assemblies, and assembly components in relevant operation scenarios, and validation of the modeling tools that accurately describe the performance of Lightbridge Fuel™ in the relevant conditions.
- **NRC Engagement Plan**: Prepare and submit the Nuclear Regulatory Commission (NRC) Engagement Plan that outlines how and when Lightbridge will engage the NRC regarding submission of relevant information and supporting documentation for license applications.
- **Fabrication:** Continue manufacturing efforts relating to establishing a manufacturing process for the co-extrusion of cladded rodlets for loop irradiation testing and other fuel testing. In addition, we plan to complete site selection and begin deployment of a Lightbridge Pilot Fuel Fabrication Facility (LPFFF) with capacity to produce fuel samples, fuel coupons, fuel rodlets, and full-length fuel rods for lead test rods and lead test assemblies for demonstration of our fuel in commercial reactors.
- **Thermal-Hydraulic Analysis and Experiments:** Perform thermal-hydraulic modeling of Lightbridge Fuel™ to prepare for a series of thermal-hydraulic experiments to confirm pressure drop, critical heat flux performance, and other thermal-hydraulic parameters of Lightbridge Fuel™ under various operating conditions in different types of reactors.

#### Table of Contents

The long-term milestones towards development and commercialization of nuclear fuel assemblies include, among other things, irradiating nuclear material samples and prototype fuel rods with enriched uranium in test reactors, conducting post-irradiation examination of irradiated material samples and/or prototype fuel rods, performing thermal-hydraulic experiments, performing seismic and other out-of-reactor experiments, performing advanced computer modeling and simulations to support fuel qualification, designing a lead test assembly (LTA), entering into a lead test rod/assembly agreement(s) with a host reactor(s), demonstrating the production process of lead test rods and/or lead test assemblies at a pilot-scale fuel fabrication facility and demonstrating the operation of lead test rods and/or lead test assemblies in commercial reactors.

The above future steps describe our current proposed approach to deploying Lightbridge Fuel™ in CANDU and/or U.S. pressurized water reactors (PWRs).

There are inherent uncertainties in the cost and outcomes of the many steps needed for successful deployment of our fuel in commercial nuclear reactors, which makes it difficult to accurately predict the timing of the commercialization of our nuclear fuel technology. However, based on our best estimate and assuming adequate R&D funding levels, we expect to begin demonstration of lead test rods and/or possibly LTAs with our metallic fuel in commercial reactors in the 2030s and begin receiving purchase orders for initial fuel reload batches from utilities 15-20 years from now, with deployment of our nuclear fuel in the first reload batch in a commercial reactor taking place approximately two years thereafter. We are exploring ways of shortening this timeframe that may include securing access to expanded irradiation test loop capacity in existing or new research reactor facilities. Lightbridge aims to engage early with relevant nuclear regulators to inform our future R&D activities.

### CRITICAL ACCOUNTING ESTIMATES

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make a variety of estimates and assumptions that affect (i) the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and (ii) the reported amounts of revenues and expenses during the reporting periods covered by the financial statements. For a discussion of the accounting judgments and estimates that we have identified as critical in the preparation of our financial statements, please see “Critical Accounting Estimates” under Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on March 3, 2025. There have been no significant changes in our critical accounting policies and estimates during the three months ended March 31, 2025.

Our management expects to make judgments and estimates about the effect of matters that are inherently uncertain. As the number of variables and assumptions affecting the future resolution of the uncertainties increase, these judgments become even more subjective and complex. Although we believe that our estimates and assumptions are reasonable, actual results may differ significantly from these estimates. Changes in estimates and assumptions based upon actual results may have a material impact on our results of operations and/or financial condition.

### Operating Expenses

#### General and Administrative

General and administrative expenses consist mostly of compensation and related costs for personnel and facilities, stock-based compensation, finance, human resources, information technology, fees for consulting and other professional services. Professional services are principally comprised of legal, audit, strategic advisory services, and outsourcing services.

General and administrative expenses increased by $1.3 million for the three months ended March 31, 2025, as compared to the three months ended March 31, 2024. The increase primarily consisted of an increase in employee compensation and employee benefits of $0.2 million, an increase in consulting fees of $0.1 million, an increase in professional fees of $0.4 million, and an increase in stock-based compensation of $0.7 million primarily due to the accelerated vesting of RSAs issued to a former employee of $0.5 million, partially offset by a decrease in information technology and recruitment expenses of $0.1 million.

Total stock-based compensation included in general and administrative expenses was $1.1 million and $0.4 million for three months ended March 31, 2025 and March 31, 2024, respectively.

#### Research and Development

R&D expenses consist primarily of costs associated with our CRADA and SPPA agreements with INL, employee compensation and related fringe benefits including stock-based compensation and other R&D costs for the development of our Lightbridge Fuel™.

The following table presents our total R&D expenses, including internal costs and other outside R&D costs, for the three months ended March 31, 2025 and 2024 (rounded to millions):

|  | Three Months Ended March 31, 2025 | 2024 |
| --- | ---: | ---: |
| INL Project | $0.8 | $0.4 |
| Romania Feasibility Study | — | 0.1 |
| Centrus Energy FEED Study | — | 0.2 |
| Allocated employee compensation and stock-based compensation expenses | 0.8 | 0.2 |
| Other outside R&D expenses | 0.1 | 0.1 |
| Total | $1.7 | $1.0 |

R&D expenses increased by $0.7 million for the three months ended March 31, 2025, as compared to the three months ended March 31, 2024, due to the increase in R&D activities related to the development of Lightbridge Fuel™. This increase primarily consisted of an increase in INL project labor costs of $0.4 million, and an increase in allocated employee compensation and employee benefits and stock-based compensation expenses of $0.6 million, partially offset by a decrease in R&D expenses of $0.3 million due to two completed R&D studies in 2024.

Total stock-based compensation included in research and development expenses was $0.2 million and $0.1 million for the three months ended March 31, 2025 and 2024, respectively.

We currently anticipate investing approximately $17.0 million in the R&D of our nuclear fuel for the full year 2025. This future budgeted R&D spending for the next 12 months is uncertain and actual spending may differ.

Due to the nature of our R&D expenditures, future costs and schedule estimates are inherently uncertain and can vary significantly as new information and the outcome of these R&D activities become available. Our future business operations are dependent on budgetary constraints due primarily to market conditions and the uncertainty of future liquidity and capital resources available to us to conduct our future R&D activities.

#### Table of Contents

#### Other Income

The Company’s other income, consisting of interest income earned from the purchase of treasury bills and from our bank savings account for the three months ended March 31, 2025, was relatively constant, as compared to the three months ended March 31, 2024.

### LIQUIDITY, CAPITAL RESOURCES AND FINANCIAL POSITION

### Liquidity Outlook

We measure liquidity in terms of our ability to fund the cash requirements of our R&D activities and our general and administrative expenses, including our contractual obligations and other commitments. We believe that based on our current level of operating expenses and currently available cash resources, we will have sufficient funds available to cover our business activities and operating cash needs for the next 12 months. In order to meet these long-term cash requirements for future planned operations to develop and commercialize our nuclear fuel, including any additional expenditures that may result from unexpected developments, it will be necessary for our project to receive direct or indirect funding and/or in-kind support from government and/or strategic partners and/or other third-party sources.

At March 31, 2025, we had cash and cash equivalents of $56.9 million, as compared to $40.0 million at December 31, 2024, an increase of $16.9 million. We raised net proceeds of $20.2 million from the sale of approximately 2.6 million shares of common stock for the three months ended March 31, 2025. Our net cash used in operating activities for the three months ended March 31, 2025, was $3.3 million and our cash flow projections indicate that we will have continued negative cash flows for the foreseeable future. We currently do not anticipate any incoming cash flows, other than the sale of common stock through our at-the-market (ATM) offering. We are not profitable, and we cannot provide any assurance that we will become profitable in the future. We will continue to incur losses because we are in the early R&D development stage of our nuclear fuel.

To complete the development and commercial deployment of Lightbridge Fuel™ we currently estimate a total R&D, including capital expenditures investment in the range of $200 million to $300 million or approximately $20.0 million per year over the next 10-15 years. We plan to raise this capital through a combination of strategic and financial investors, as well as potentially receiving grants from the DOE and/or other government sources.

Sufficient funding is needed to continue our nuclear fuel development project and to achieve our future R&D milestones leading to the commercialization of our nuclear fuel. The actual amount of cash we will need to reach the commercialization of our nuclear fuel is subject to many factors, including, but not limited to, the timing, design and conduct of the R&D work at the DOE’s national laboratories for our fuel along with other costs to commercialize our nuclear fuel. Accordingly, there is high potential for budget variances in the current above cost projections and fuel development timelines of our current planned operations over the above cited fuel development period. Currently, we plan to continue to utilize our ATM to finance our future R&D and general and administrative activities.

We will also need to receive substantial funding and in-kind support from government, strategic partners and/or other third-party sources throughout our nuclear fuel R&D development period in order to fund our ongoing R&D efforts in the future. If we are unable to obtain such funding and/or in-kind support that meets our future R&D cash requirements, we will need to seek other funding, which may include the issuance of additional shares of the Company’s common stock, if available. This will result in dilution to our existing stockholders. If we can raise additional funds through the issuance of preferred stock, other equity or convertible securities, these securities could have rights or preferences senior to those of our common stock and could contain covenants that restrict our operations in the future. There can be no assurance that we will be able to obtain additional equity or debt financing on terms acceptable to us, if at all.

We have approximately $61 million of working capital as of the date of this filing and this amount exceeds our anticipated cash requirements for the next 12 months. We currently project a negative cash flow from our operations from both our general and administrative and R&D expenses, resulting in total expected expenditures of approximately $25.0 million for the full year 2025. Our R&D expenses are expected to increase over the next 12 months as we continue advancing our nuclear fuel development program. There are inherent uncertainties in forecasting the R&D and other expenditures that will be required in the future. We may also be unsuccessful in raising the capital necessary in the future to continue the R&D development of our fuel. Once other anticipated agreements are finalized or other future R&D agreements are entered into and the future R&D expenses are known, we expect to incur a significantly higher level of future required R&D expenses to further develop our fuel, resulting in higher negative monthly cash flows from operations in future periods.

24

#### Table of Contents

Our current source of cash available to us for the next 12 months, in addition to cash and cash equivalents on hand, is the potential funding from equity issuances pursuant to the at-the-market equity offering sales agreement, as amended, with Stifel, Nicolaus & Company, Incorporated. We filed a shelf registration statement on Form S-3 with the Securities and Exchange Commission (SEC) on March 29, 2024, registering the sale of up to $75.0 million of the Company’s securities that was declared effective on April 19, 2024. On May 10, 2024, we filed a prospectus supplement, which was further supplemented on July 19, 2024 and August 9, 2024 (collectively, the “First Prospectus Supplement”) pursuant to which we may offer and sell shares of common stock having an aggregate offering price of up to $12.6 million from time to time, through the ATM. The Company exhausted all sales under the First Prospectus Supplement. On November 22, 2024, we filed a prospectus supplement pursuant to which we may offer and sell shares of common stock having an aggregate offering price of up to $45.0 million from time to time through the ATM.

Although we expect this ATM offering to continue to be our primary source of working capital for the Company in 2025, there is no assurance that an ATM financing arrangement will be available to us in the future. See Note 7. Stockholders’ Equity and Stock-Based Compensation of the Notes to our Unaudited Condensed Consolidated Financial Statements included in Part I. Item 1. *Financial Statements,* of this Quarterly Report on Form 10-Q for information regarding our prior equity financings.

We have no debt or lines of credit, and we have financed our operations to date through the sale of our preferred stock and common stock. Management believes that public or private equity investments may be available in the future; however, adverse market conditions, in our common stock price and trading volume, as well as other factors could substantially impair our ability to raise capital in the future and continue developing our nuclear fuel.

### Short-Term and Long-Term Liquidity Sources

Currently, our primary source of liquidity is cash raised from our ATM offering.

As discussed above, we will seek new financing in order to bring us additional sources of capital, depending on the capital market conditions of our common stock. There can be no assurance that these additional sources of capital will be made available on terms acceptable to us, or at all. The primary potential sources of cash that may be available to us are as follows:

- equity or debt investment from third-party investors in Lightbridge;
- collaboration with potential industry partners; and
- strategic investment and/or government funding to support the remaining R&D activities required to continue the development of our fuel products and move them to a commercial stage.

In support of our long-term business with respect to our fuel technology business, we endeavor to create strategic alliances with other parties to support the remaining R&D activities that are required to further enhance and complete the development of our fuel products to a commercial stage. We may be unable to form such strategic alliances on terms acceptable to us or at all.

See Note 7. Stockholders’ Equity and Stock-Based Compensation of the Notes to our Unaudited Condensed Consolidated Financial Statements included in Part I. Item 1. *Financial Statements,* of this Quarterly Report on Form 10-Q for information regarding our prior equity financings.

### Cash Flow

The following table provides detailed information about our net cash flows for the three months ended March 31, 2025 and 2024 (rounded in millions):

|  | Three Months Ended March 31, 2025 | 2024 |

Cash used in operating activities increased by $1.4 million for the three months ended March 31, 2025 as compared to the three months ended March 31, 2024. This increase was primarily due to increased spending on R&D and general and administrative expenses.

#### Financing Activities

Cash provided by financing activities increased by $19.0 million for the three months ended March 31, 2025 as compared to the three months ended March 31, 2024. This increase was primarily due to an increase in the net proceeds received from the issuance of common stock under our ATM offering of $19.0 million and net proceeds from the exercise of stock options of 0.2 million, partially offset by an increase in net share settlement of equity awards for the payment of withholding taxes of $0.2 million.

Cash provided by our ATM offering was $20.2 million (sale of approximately 2.6 million common shares) and $1.2 million (sale of approximately 0.4 million common shares) for the three months ended March 31, 2025 and 2024, respectively.

### Evaluation of Disclosure Controls and Procedures

The Company maintains disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the Exchange Act)) that are designed to provide reasonable assurance that information required to be disclosed by the Company in the reports that it files or submits under the Exchange Act is (a) recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms, and (b) accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating such controls and procedures, the Company recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives.

Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of March 31, 2025.
