(&#8220;TPI&#8221;), which was incorporated in the state of Delaware on January 8, 1992 (subsequently and collectively referred to as &#8220;we&#8221; or the &#8220;Company&#8221;). On September 29, 2009, the Company changed its name from Thorium Power, Ltd. to Lightbridge Corporation and began its focus on developing and commercializing metallic nuclear fuels. The Company is a nuclear fuel technology company developing and working to commercialize it next generation nuclear fuel technology.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong><em>Going Concern, Liquidity and Management&#8217;s Plan</em></strong></p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">While the Company&#8217;s cash at March 31, 2021 exceeds its currently budgeted expenditures through the first quarter of 2022, there are inherent uncertainties in forecasting future expenditures, especially forecasting for uncertainties such as future research and development (R&amp;D) costs and how the COVID-19 outbreak may affect future costs and operations. Also, the cash requirements of the Company&#8217;s future planned operations to commercialize its nuclear fuel, including any additional expenditures that may result from unexpected developments, requires it to raise significant additional capital including receiving government support. The Company will need to seek its shareholders&#8217; approval in 2021 to increase the number of its authorized common shares for future equity financings, in order for the Company to continue to fund its future operations. Taking into account these uncertainties as well as the updated projected fuel development timeline of 15-20 years to commercialization, projected operational costs to keep the fuel development project on schedule and the various risks of developing and commercializing its nuclear fuel, these factors raise substantial doubt about the Company&#8217;s ability to continue as a going concern for the 12 months following the date of this filing. To the extent any uncertainties reduce the Company&#8217;s liquidity for the next 12 months, the Company will consider, if available, additional debt or equity raises and delaying certain expenditures, including delaying R&amp;D expenses, until sufficient capital becomes available.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <table style="border-spacing:0;font:10pt times new roman;width:100%" cellpadding="0"> <tr style="height:15px"> <td class="hpbhr">&nbsp;</td></tr> <tr style="height:15px"> <td style="BORDER-BOTTOM: black 1px solid; TEXT-INDENT: 0px;text-align:center;">7</td></tr> <tr style="height:15px"> <td><p style='page-break-after: always'></p></td></tr> <tr style="height:15px"> <td><em><a href="#toc">Table of Contents</a></em></td></tr></table> <p style="font-size:10pt;font-family:times new roman;margin:0px">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">At March 31, 2021, the Company had approximately $15.2 million in cash and had a working capital surplus of approximately $15.2 million. The Company&#8217;s net cash used in operating activities for the three months ended March 31, 2021 was approximately $6.3 million, and current projections indicate that the Company will have continued negative cash flows for the foreseeable future. Net losses incurred for the three months ended March 31, 2021 and 2020 amounted to approximately $(2.0) million and $(2.3) million, respectively. As of March 31, 2021, the Company had an accumulated deficit of approximately $131.2 million, representative of recurring losses since inception. The Company had incurred recurring losses since inception and it will continue to incur losses because it is in the early development stage of commercializing its nuclear fuel. </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The Company&#8217;s plans to fund future operations include: (1) raising additional capital through future equity issuances or convertible debt financings; (2) additional funding through new relationships to help fund future R&amp;D costs; and (3) seeking other sources of capital. The Company may issue securities, including common stock, preferred stock, and stock purchase contracts through private placement transactions or registered public offerings, pursuant to future registration statements. The current Form S-3 was filed with the SEC on March 25, 2021 registering the sale of up to $75 million of the Company&#8217;s securities and declared effective on April 5, 2021. There can be no assurance as to the future availability of equity capital or the acceptability of the terms upon which financing and capital might become available. The Company&#8217;s future liquidity needs to develop its nuclear fuel are long-term, and the ability to address those needs, and the ability to raise capital will largely be determined by the success of the development of its nuclear fuel, key nuclear development and government regulatory events, and its business decisions in the future. </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong><em>Basis of Consolidation</em></strong></p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">These condensed consolidated financial statements include the accounts of Lightbridge, a Nevada corporation, and the Company&#8217;s wholly-owned subsidiaries, TPI, a Delaware corporation, and Lightbridge International Holding LLC, a Delaware limited liability company.

Also, the success of the Company&#8217;s operations will be subject to other numerous contingencies, some of which are beyond management&#8217;s control. These contingencies include general and regional economic conditions, contingent liabilities, potential competition with other nuclear fuel developers, including those entities developing accident tolerant fuels, changes in government regulations, support for nuclear power, changes in accounting and taxation standards, inability to achieve overall long-term goals, future impairment charges to its assets, and global or regional catastrophic events.

In March 2020, the WHO classified the COVID-19 outbreak a pandemic, based on increase in exposure globally. The current spread of COVID-19 that is impacting global economic activity and market conditions could lead to adverse changes in the Company&#8217;s ability to conduct R&amp;D activities with the United States national labs and others. The COVID-19 outbreak has impacted our business operations and results of operations for 2020, resulting in the reduction of R&amp;D expenses and an increase in general and administrative expenses due to severance payments to former employees. However, the effects of the pandemic are fluid and changing rapidly, including with respect to vaccine and treatment developments and deployment and potential mutations of COVID-19. While the Company continues to monitor the impact of COVID-19 on its business, the Company is unable to accurately predict the ultimate impact on the results of operations, financial condition and liquidity that COVID-19 will have due to various uncertainties, including the geographic spread of the virus, the severity of the disease, the duration of the outbreak, and actions that may be taken by governmental authorities and other third-parties. </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong><em>Grant Income </em></strong></p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The Company concluded that its government grant was not within the scope of ASC Topic 606 as it did not meet the definition of a contract with a customer. Additionally, the Company concluded that the grant met the definition of a contribution and the grant is a non-reciprocal transaction. The Company determined that Subtopic 958-605, Not-for-Profit-Entities-Revenue Recognition did not apply, as the Company is a business entity and the grant is received from governmental agencies.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">In the absence of applicable guidance under U.S. generally accepted accounting principles (&#8220;U.S. GAAP&#8221;), the Company&#8217;s management developed a policy to recognize grant income at the time the related costs are incurred and the right to payment is realized.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The Company believes this policy is consistent with the overarching premise in ASC Topic 606, to ensure that revenue recognition reflects the transfer of promised goods or services to customers in an amount that reflects the consideration that we expect to be entitled to in exchange for those goods or services, even though there is no exchange as defined in ASC Topic 606. Additionally, the Company determined that the recognition of grant income as costs are incurred and amounts become realizable is analogous to the concept of transfer of control of a service over time under ASC Topic 606.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Further, the Company believes that showing grant income on a gross method, with the grant income shown as other operating income and the related costs as a charge to R&amp;D expense, rather than depicting the grant income as a reduction of R&amp;D expense, is a more meaningful presentation. </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The Company recognized grant income of approximately $0.1 million and $0 for the three months ended March 31, 2021 and 2020, respectively.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <table style="border-spacing:0;font:10pt times new roman;width:100%" cellpadding="0"> <tr style="height:15px"> <td class="hpbhr">&nbsp;</td></tr> <tr style="height:15px"> <td style="BORDER-BOTTOM: black 1px solid; TEXT-INDENT: 0px;text-align:center;">9</td></tr> <tr style="height:15px"> <td><p style='page-break-after: always'></p></td></tr> <tr style="height:15px"> <td><em><a href="#toc">Table of Contents</a></em></td></tr></table> <p style="font-size:10pt;font-family:times new roman;margin:0px">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong>Patents and Trademarks</strong></p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Through September 30, 2020, patents were stated on the consolidated balance sheets at cost. Costs, such as filing fees with patent granting agencies and legal fees directly relating to those filings, incurred to file patent applications were capitalized when the Company believed that there was a high likelihood that the patent would be issued and there would be future economic benefit associated with the patent. These costs were amortized from the date of the patent application on a straight-line basis over the estimated useful life of 20 years, which is the legal life of the patent. All costs associated with abandoned patent applications were expensed. The Company expensed patent annuity fees as these fees were maintenance fees required by the patent office at certain points in time after a patent was granted in order to keep the patent legal rights in force. During the years ended December 31, 2020 and 2019, these patent annuity fees were insignificant. In the fourth quarter of 2020, the remaining patent costs were written-off as impaired.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Beginning January 1, 2021, patent filing fees with patent granting agencies and legal fees directly relating to those filings, incurred to file patent applications were expensed as the Company believes that there is not a high likelihood that there will be a future economic benefit associated with the patents, due to the uncertainties in the current fuel development timelines and the patents being commercialized. The Company continues to expense patent annuity fees as these fees are maintenance fees required by the patent office at certain points in time after a patent is granted, in order to keep the patent legal rights in force. As of March 31, 2021, and December 31, 2020 the carrying value of the patents on the balance sheets was $0.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Costs for filing and legal fees for trademark applications are capitalized. Trademarks are considered intangible assets with an indefinite useful life and therefore should not be amortized. The Company performed an impairment test in the fourth quarter of 2020 and 2019 and no impairment of the trademarks was identified. As of March 31, 2021 and December 31, 2020, the carrying value of trademarks was approximately $0.1 million for both balance sheet dates. </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong><em>Leases</em></strong></p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">In accordance with ASU 2016-02, <em>Leases (Topic 842)</em>, which requires recognition of most lease arrangements on the balance sheet, the Company recognizes operating lease right of use assets and liabilities at commencement date based on the present value of the future minimum lease payments over the lease term. Leases with an initial term of 12 months or less are not recorded on the consolidated balance sheet in accordance with the short-term lease recognition exemption. The Company applies the practical expedient to non-separate and non-lease components for all leases that qualify. Lease expense is recognized on a straight-line basis over the lease term. The Company has only one lease for office rent and the lease is for a term of 12 months without renewal options.

ASU 2020-06 will simplify the accounting for convertible instruments by reducing the number of accounting models for convertible debt instruments and convertible preferred stock. Limiting the accounting models will result in fewer embedded conversion features being separately recognized from the host contract as compared with current U.S. GAAP. Convertible instruments that continue to be subject to separation models are (1) those with embedded conversion features that are not clearly and closely related to the host contract, that meet the definition of a derivative, and that do not qualify for a scope exception from derivative accounting and (2) convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in capital. ASU 2020-06 also amends the guidance for the derivatives scope exception for contracts in an entity&#8217;s own equity to reduce form-over-substance-based accounting conclusions. ASU 2020-06 will be effective July 1, 2024, for the Company. Early adoption is permitted, but no earlier than January 1, 2021, including interim periods within that year.

The Company can exercise this option only if it also requires the conversion of the Series A Preferred Stock in the same proportion as it is requiring of the Series B Preferred Stock.

At $28.08 per share the common stock into which the Series B Preferred Stock was initially convertible was valued at approximately $6.2 million.

Dividends accrue on the Series A Preferred Stock at the rate of 7% per year and will be paid in-kind through an increase in the liquidation preference per share. The liquidation preference, initially $2.7451 per share of Series A Preferred Stock, is the base that is also used to determine the number of common shares into which the Series A Preferred Stock will convert as well as the calculation of the 7% dividend. Each share of Series A Preferred Stock is convertible at the option of the holder into such number of shares of the Company&#8217;s common stock equal to the liquidation preference divided by the conversion price of $32.94 per share subject to adjustments in the case of stock splits and stock dividends.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Holders of the Series A Preferred Stock are also entitled to participating dividends whenever dividends in cash, securities (other than shares of the Company&#8217;s common stock) or property are paid on common shares.

The average of the high and low market prices of the common stock on August 6, 2016, the date of the closing of the sale of the Series A Preferred Stock, was approximately $39.78 per share. At $39.78 per share the common stock into which the Series A Preferred Stock was initially convertible was valued at approximately $3.4 million. This amount was compared to the $2.8 million of proceeds of the Series A Preferred Stock to indicate that a BCF of approximately $0.6 million existed at the date of issuance in 2016, which was immediately accreted as a deemed dividend because the conversion rights were immediately effective.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Additionally, comparison of the $2.7451, original conversion price of the PIK dividends prior to the one-for-twelve reverse stock split on October 21, 2019, to the $3.315 commitment date fair value per share indicates that each PIK dividend will accrete $0.5699 of BCF as an additional deemed dividend for every $2.7451 of PIK dividend accrued.

Our nuclear fuel could significantly improve the economics, safety, and proliferation resistance of nuclear fuel in existing and new nuclear reactors, large and small, with a meaningful impact on addressing climate change, and air pollution, all while benefiting national security. We project that the world&#8217;s energy and climate needs can only be met if nuclear power&#8217;s share of the energy-generating mix grows substantially in the coming decades. We are developing our nuclear fuel to enable that to happen. In particular, we are focusing on the potential for large numbers of small modular reactors (SMRs) that we believe can benefit from our fuel with improved economics and load following when included on an electric grid with renewables. Today, there are approximately 440 operable power reactors worldwide, of which about 400 are operating. We expect slow net growth in this number as old reactors close and fewer new large reactors are built, due to the inherent challenges facing new build large reactors, including regulatory and political challenges, financings, and the ability for large reactors to be profitable without running constantly.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <table style="border-spacing:0;font:10pt times new roman;width:100%" cellpadding="0"> <tr style="height:15px"> <td class="hpbhr">&nbsp;</td></tr> <tr style="height:15px"> <td style="BORDER-BOTTOM: black 1px solid; TEXT-INDENT: 0px;text-align:center;">24</td></tr> <tr style="height:15px"> <td><p style='page-break-after: always'></p></td></tr> <tr style="height:15px"> <td><em><a href="#toc">Table of Contents</a></em></td></tr></table> <p style="font-size:10pt;font-family:times new roman;margin:0px">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">We believe our metallic fuel will offer significant economic and safety benefits over traditional fuel, primarily because of the superior heat transfer properties of all-metal fuel and the resulting lower operating temperature of the fuel. We also believe that uprating a reactor with Lightbridge Fuel&#8482; will add incremental electricity at a lower levelized cost than any other means of generating baseload electric power, including any renewable, fossil, or hydroelectric energy source, or any traditional nuclear fuel.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Emerging nuclear technologies that many in the industry believe have the potential to generate massive amounts of power include SMRs, which are now in the development and licensing phases. We expect that Lightbridge Fuel&#8482; can provide SMRs with all the benefits our technology brings to large reactors, with the benefits being more meaningful to the economic case for deployment of SMRs. Lightbridge Fuel&#8482; is expected to generate more power in SMRs than traditional nuclear fuels, which will help decarbonize sectors that are now powered by fossil fuels. We also plan to explore using Lightbridge Fuel&#8482; in new SMRs to produce hydrogen for liquid non-carbon fuels for use in other, hard-to-decarbonize sectors such as aviation and shipping. Our ongoing research and development (R&amp;D) initiatives are entirely compatible with Lightbridge Fuel&#8482; powering SMRs for multiple purposes. The first SMRs that could use our fuel are expected to begin operations in 2029.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">We have built a significant portfolio of patents reflecting years of R&amp;D, and we anticipate testing of our fuel through third party vendors and others, including the United States Department of Energy (DOE) national laboratories.

This demonstration of Lightbridge&#8217;s proprietary manufacturing process uses an internally developed and patented high-temperature coextrusion process. The six-foot length of the surrogate rods is the typical length of the fuel rods used by many small modular reactors (SMRs) now in development and licensing. Future fabrication of high-assay low-enriched uranium (HALEU) rodlets for loop irradiation testing in the Advanced Test Reactor, and ultimately commercial length HALEU fuel rods, will use similar extrusion and casting techniques to create material chemistry and grain structures representative of Lightbridge Fuel&#8482;. Performing fabrication development activities with surrogate materials allows Lightbridge to use a broader range of suppliers and is a cost-effective approach as it does not require uranium material.</p></td></tr> <tr style="height:15px"> <td> <p style="margin:0px">&nbsp;</p></td> <td> <p style="margin:0px">&nbsp;</p></td> <td> <p style="margin:0px">&nbsp;</p></td></tr> <tr style="height:15px"> <td style="width:4%;"> <p style="margin:0px">&nbsp;</p></td> <td style="width:4%;vertical-align:top;"> <p style="margin:0px"><font style="font-family:symbol">&#183;</font></p></td> <td style="vertical-align:top;"> <p style="MARGIN: 0px; text-align:justify;">On March 25, 2021, the Company was awarded a second voucher from the DOE&#8217;s GAIN program to support development of Lightbridge Fuel&#8482; in collaboration with the Pacific Northwest National Laboratory (PNNL).

Ultimately, we settled on the ATR at INL and applied to DOE for and won a GAIN Voucher in December 2019 to kick off our initial collaboration with the U.S. national laboratory complex. Our initial understanding was that we would have access to a government-funded PWR water test loop in the ATR to generate sufficient data to support our lead test assembly (LTA) testing and eliminate the need for lead test rod (LTR) testing in a large commercial reactor. However, while the ATR has enough space for four test loops where fuel rods can be irradiated, the reactor currently has only one such test loop, limiting how much fuel rod material that can be inserted into the reactor as well as its duration in the reactor. We believe that INL could add up to all three additional test loops, which we have determined to be an unmanageable cost for Lightbridge. We plan to work with the government and industry to have those test loops added without Lightbridge paying for them. We believe we have strong arguments for the government to pay most of the cost for the additional test loops.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <table style="border-spacing:0;font:10pt times new roman;width:100%" cellpadding="0"> <tr style="height:15px"> <td class="hpbhr">&nbsp;</td></tr> <tr style="height:15px"> <td style="BORDER-BOTTOM: black 1px solid; TEXT-INDENT: 0px;text-align:center;">26</td></tr> <tr style="height:15px"> <td><p style='page-break-after: always'></p></td></tr> <tr style="height:15px"> <td><em><a href="#toc">Table of Contents</a></em></td></tr></table> <p style="font-size:10pt;font-family:times new roman;margin:0px">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">If new test loops are not added to the ATR, loop irradiation testing in the ATR may not provide sufficient data to justify regulatory approval for LTA testing in a large commercial PWR in a commercially feasible timeframe. This would likely necessitate an extra fuel development step of LTR testing in a large commercial PWR in addition to the ATR loop testing before LTA testing could commence. As a result, our fuel development timelines would be extended to 15-20 years before securing our first orders for batch reloads in large commercial PWRs. Consequently, the projected fuel development costs would increase substantially, making it unfeasible for Lightbridge to fund this fuel development effort on our own.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong><u>CRITICAL ACCOUNTING POLICIES AND ESTIMATES</u></strong></p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">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.

The Company&#8217;s net cash used in operating activities for the three months ended March 31, 2021 was approximately $6.3 million, and current projections indicate that the Company will have continued negative operating cash flows until the commercialization of its nuclear fuel. </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">We have approximately $14.8 million of working capital as of the date of this filing. We currently project a negative cash flow from our current operations averaging approximately $0.8 million per month for our general and administrative and total R&amp;D expenses, for total expected expenditures of approximately $9 million to $10 million for the next 12 to 15 months. We believe that our current working capital exceeds our budgeted expenditures through the first quarter of 2022. However, there are inherent uncertainties in forecasting future required R&amp;D expenditures, as we are currently working on establishing our first fuel development agreements with the DOE&#8217;s National Laboratories. Once many of these agreements are finalized and the future R&amp;D costs are known, we expect to forecast a significantly higher level of future required R&amp;D expenses and higher negative monthly cash flows from operations.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <table style="border-spacing:0;font:10pt times new roman;width:100%" cellpadding="0"> <tr style="height:15px"> <td class="hpbhr">&nbsp;</td></tr> <tr style="height:15px"> <td style="BORDER-BOTTOM: black 1px solid; TEXT-INDENT: 0px;text-align:center;">29</td></tr> <tr style="height:15px"> <td><p style='page-break-after: always'></p></td></tr> <tr style="height:15px"> <td><em><a href="#toc">Table of Contents</a></em></td></tr></table> <p style="font-size:10pt;font-family:times new roman;margin:0px">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">If sufficient funding becomes available to us, our R&amp;D activities may significantly increase in the future. This funding is needed to continue our fuel development project and to achieve our future R&amp;D milestones. COVID-19 may also affect costs and future operations by potentially delaying our work at the DOE&#8217;s National Laboratories. The actual amount of cash we will need to operate is subject to many factors, including, but not limited to, the timing, design and conduct of the R&amp;D work at the DOE&#8217;s National Laboratories for our fuel along with cost to commercialize our nuclear fuel. Accordingly, there is high potential for budget variances in the current cost projections and fuel development timelines of our current planned operations over the fuel development period. Currently, we will seek shareholder approval on May 27, 2021 to increase the number of authorized common shares, which is needed in order for us to finance our current and future R&amp;D and corporate activities through future equity financing. </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">We will also need to receive substantial U.S. government support throughout our nuclear fuel R&amp;D period in order to fund our R&amp;D efforts in the future. If we are unable to obtain this government funding that meets our future R&amp;D cash requirements, we will need to seek other funding, 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. </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Considering the above-mentioned uncertainties and lack of financial resources to fund our current and long-term fuel development costs and corporate overhead expenses, substantial doubt exists about the Company&#8217;s ability to continue as a going concern for the 12 months following the date of this filing. We have the ability to delay or reduce certain operating expenses, including R&amp;D expenses in the next 12 to 15 months, which could reduce our cash flow shortfall. However, this delay would also extend our projected fuel development timeline discussed above. </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The current primary sources of cash available to us for the next 12 months are potential funding from equity issuances, including potential future at-the-market financing under our at-the-market equity offering sales agreement, as amended, with Stifel, Nicolaus &amp; Company, Incorporated, and U.S. government support. The Company has an effective Form S-3 that was filed with the SEC on March 25, 2021 registering the sale of up to $75 million of the Company&#8217;s securities and declared effective on April 5, 2021. Due to the offering limitations currently applicable under General Instruction I.B.6. of Form S-3 and the market valuation of our current public float, we are currently limited on the amount of funding available under a new shelf registration statement. We have no debt or lines of credit and we have financed our operations to date through our prior years&#8217; consulting revenue margins and 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 like COVID-19 could substantially impair our ability to raise capital in the future and to continue the nuclear fuel development project. </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong><em>Short-Term and Long-Term Liquidity Sources</em></strong></p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">As discussed above, we will seek new financing bringing us additional sources of capital, depending on the capital market conditions of our common stock and us obtaining shareholder approval to increase the current number of authorized common shares, over the next 12 months.

Results for the interim period presented are not necessarily indicative of the results that might be expected for the entire fiscal year. When used in these notes, the terms &amp;#8220;Lightbridge&amp;#8221;, &amp;#8220;Company,&amp;#8221; &amp;#8220;we,&amp;#8221; &amp;#8220;us&amp;#8221; or &amp;#8220;our&amp;#8221; mean Lightbridge Corporation and all entities included in our condensed consolidated financial statements.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;The Company was formed on October 6, 2006, when Thorium Power, Ltd., which was incorporated in the state of Nevada on February 2, 1999, merged with Thorium Power, Inc. (&amp;#8220;TPI&amp;#8221;), which was incorporated in the state of Delaware on January 8, 1992 (subsequently and collectively referred to as &amp;#8220;we&amp;#8221; or the &amp;#8220;Company&amp;#8221;). On September 29, 2009, the Company changed its name from Thorium Power, Ltd. to Lightbridge Corporation and began its focus on developing and commercializing metallic nuclear fuels. The Company is a nuclear fuel technology company developing and working to commercialize it next generation nuclear fuel technology.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&lt;strong&gt;&lt;em&gt;Going Concern, Liquidity and Management&amp;#8217;s Plan&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;While the Company&amp;#8217;s cash at March 31, 2021 exceeds its currently budgeted expenditures through the first quarter of 2022, there are inherent uncertainties in forecasting future expenditures, especially forecasting for uncertainties such as future research and development (R&amp;amp;D) costs and how the COVID-19 outbreak may affect future costs and operations. Also, the cash requirements of the Company&amp;#8217;s future planned operations to commercialize its nuclear fuel, including any additional expenditures that may result from unexpected developments, requires it to raise significant additional capital including receiving government support. The Company will need to seek its shareholders&amp;#8217; approval in 2021 to increase the number of its authorized common shares for future equity financings, in order for the Company to continue to fund its future operations. Taking into account these uncertainties as well as the updated projected fuel development timeline of 15-20 years to commercialization, projected operational costs to keep the fuel development project on schedule and the various risks of developing and commercializing its nuclear fuel, these factors raise substantial doubt about the Company&amp;#8217;s ability to continue as a going concern for the 12 months following the date of this filing. To the extent any uncertainties reduce the Company&amp;#8217;s liquidity for the next 12 months, the Company will consider, if available, additional debt or equity raises and delaying certain expenditures, including delaying R&amp;amp;D expenses, until sufficient capital becomes available.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&amp;nbsp; &lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;At March 31, 2021, the Company had approximately $15.2 million in cash and had a working capital surplus of approximately $15.2 million. The Company&amp;#8217;s net cash used in operating activities for the three months ended March 31, 2021 was approximately $6.3 million, and current projections indicate that the Company will have continued negative cash flows for the foreseeable future. Net losses incurred for the three months ended March 31, 2021 and 2020 amounted to approximately $(2.0) million and $(2.3) million, respectively. As of March 31, 2021, the Company had an accumulated deficit of approximately $131.2 million, representative of recurring losses since inception. The Company had incurred recurring losses since inception and it will continue to incur losses because it is in the early development stage of commercializing its nuclear fuel. &lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;The Company&amp;#8217;s plans to fund future operations include: (1) raising additional capital through future equity issuances or convertible debt financings; (2) additional funding through new relationships to help fund future R&amp;amp;D costs; and (3) seeking other sources of capital. The Company may issue securities, including common stock, preferred stock, and stock purchase contracts through private placement transactions or registered public offerings, pursuant to future registration statements. The current Form S-3 was filed with the SEC on March 25, 2021 registering the sale of up to $75 million of the Company&amp;#8217;s securities and declared effective on April 5, 2021. There can be no assurance as to the future availability of equity capital or the acceptability of the terms upon which financing and capital might become available. The Company&amp;#8217;s future liquidity needs to develop its nuclear fuel are long-term, and the ability to address those needs, and the ability to raise capital will largely be determined by the success of the development of its nuclear fuel, key nuclear development and government regulatory events, and its business decisions in the future. &lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&lt;strong&gt;&lt;em&gt;Basis of Consolidation&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;These condensed consolidated financial statements include the accounts of Lightbridge, a Nevada corporation, and the Company&amp;#8217;s wholly-owned subsidiaries, TPI, a Delaware corporation, and Lightbridge International Holding LLC, a Delaware limited liability company. These wholly-owned subsidiaries are inactive. All significant intercompany transactions and balances have been eliminated in consolidation. &lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&lt;strong&gt;&lt;em&gt;Certain Risks, Uncertainties and Concentrations&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;The Company will need additional funding by way of a combination of strategic alliances, government grants, further offerings of equity securities, or an offering of debt securities in order to support its future R&amp;amp;D activities required to further enhance and complete the development of its fuel products to a proof of concept and a commercial stage.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;There can be no assurance that the Company will be able to successfully continue to conduct its operations if there is a lack of financial resources available in the future to continue its fuel development, and a failure to do so would have a material adverse effect on the Company&amp;#8217;s future R&amp;amp;D activities, financial position, results of operations, and cash flows. Also, the success of the Company&amp;#8217;s operations will be subject to other numerous contingencies, some of which are beyond management&amp;#8217;s control. These contingencies include general and regional economic conditions, contingent liabilities, potential competition with other nuclear fuel developers, including those entities developing accident tolerant fuels, changes in government regulations, support for nuclear power, changes in accounting and taxation standards, inability to achieve overall long-term goals, future impairment charges to its assets, and global or regional catastrophic events. The Company may also be subject to various additional political, economic, and other uncertainties.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&amp;nbsp; &lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;On January 30, 2020, the World Health Organization (&amp;#8220;WHO&amp;#8221;) announced a global health emergency because of a new strain of coronavirus originating in Wuhan, China (the &amp;#8220;COVID-19 outbreak&amp;#8221;) and the risk to the international community as the virus spreads globally beyond its point of origin. In March 2020, the WHO classified the COVID-19 outbreak a pandemic, based on increase in exposure globally. The current spread of COVID-19 that is impacting global economic activity and market conditions could lead to adverse changes in the Company&amp;#8217;s ability to conduct R&amp;amp;D activities with the United States national labs and others. The COVID-19 outbreak has impacted our business operations and results of operations for 2020, resulting in the reduction of R&amp;amp;D expenses and an increase in general and administrative expenses due to severance payments to former employees. However, the effects of the pandemic are fluid and changing rapidly, including with respect to vaccine and treatment developments and deployment and potential mutations of COVID-19. While the Company continues to monitor the impact of COVID-19 on its business, the Company is unable to accurately predict the ultimate impact on the results of operations, financial condition and liquidity that COVID-19 will have due to various uncertainties, including the geographic spread of the virus, the severity of the disease, the duration of the outbreak, and actions that may be taken by governmental authorities and other third-parties. &lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&lt;strong&gt;&lt;em&gt;Grant Income &lt;/em&gt;&lt;/strong&gt;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;The Company concluded that its government grant was not within the scope of ASC Topic 606 as it did not meet the definition of a contract with a customer. Additionally, the Company concluded that the grant met the definition of a contribution and the grant is a non-reciprocal transaction. The Company determined that Subtopic 958-605, Not-for-Profit-Entities-Revenue Recognition did not apply, as the Company is a business entity and the grant is received from governmental agencies.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;In the absence of applicable guidance under U.S. generally accepted accounting principles (&amp;#8220;U.S. GAAP&amp;#8221;), the Company&amp;#8217;s management developed a policy to recognize grant income at the time the related costs are incurred and the right to payment is realized.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;The Company believes this policy is consistent with the overarching premise in ASC Topic 606, to ensure that revenue recognition reflects the transfer of promised goods or services to customers in an amount that reflects the consideration that we expect to be entitled to in exchange for those goods or services, even though there is no exchange as defined in ASC Topic 606. Additionally, the Company determined that the recognition of grant income as costs are incurred and amounts become realizable is analogous to the concept of transfer of control of a service over time under ASC Topic 606.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;Further, the Company believes that showing grant income on a gross method, with the grant income shown as other operating income and the related costs as a charge to R&amp;amp;D expense, rather than depicting the grant income as a reduction of R&amp;amp;D expense, is a more meaningful presentation. &lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;The Company recognized grant income of approximately $0.1 million and $0 for the three months ended March 31, 2021 and 2020, respectively.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&amp;nbsp; &lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&lt;strong&gt;Patents and Trademarks&lt;/strong&gt;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;Through September 30, 2020, patents were stated on the consolidated balance sheets at cost. Costs, such as filing fees with patent granting agencies and legal fees directly relating to those filings, incurred to file patent applications were capitalized when the Company believed that there was a high likelihood that the patent would be issued and there would be future economic benefit associated with the patent. These costs were amortized from the date of the patent application on a straight-line basis over the estimated useful life of 20 years, which is the legal life of the patent. All costs associated with abandoned patent applications were expensed. The Company expensed patent annuity fees as these fees were maintenance fees required by the patent office at certain points in time after a patent was granted in order to keep the patent legal rights in force. During the years ended December 31, 2020 and 2019, these patent annuity fees were insignificant. In the fourth quarter of 2020, the remaining patent costs were written-off as impaired.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;Beginning January 1, 2021, patent filing fees with patent granting agencies and legal fees directly relating to those filings, incurred to file patent applications were expensed as the Company believes that there is not a high likelihood that there will be a future economic benefit associated with the patents, due to the uncertainties in the current fuel development timelines and the patents being commercialized. The Company continues to expense patent annuity fees as these fees are maintenance fees required by the patent office at certain points in time after a patent is granted, in order to keep the patent legal rights in force. As of March 31, 2021, and December 31, 2020 the carrying value of the patents on the balance sheets was $0.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;Costs for filing and legal fees for trademark applications are capitalized. Trademarks are considered intangible assets with an indefinite useful life and therefore should not be amortized. The Company performed an impairment test in the fourth quarter of 2020 and 2019 and no impairment of the trademarks was identified. As of March 31, 2021 and December 31, 2020, the carrying value of trademarks was approximately $0.1 million for both balance sheet dates. &lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&lt;strong&gt;&lt;em&gt;Leases&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;In accordance with ASU 2016-02, &lt;em&gt;Leases (Topic 842)&lt;/em&gt;, which requires recognition of most lease arrangements on the balance sheet, the Company recognizes operating lease right of use assets and liabilities at commencement date based on the present value of the future minimum lease payments over the lease term. Leases with an initial term of 12 months or less are not recorded on the consolidated balance sheet in accordance with the short-term lease recognition exemption. The Company applies the practical expedient to non-separate and non-lease components for all leases that qualify. Lease expense is recognized on a straight-line basis over the lease term. The Company has only one lease for office rent and the lease is for a term of 12 months without renewal options. See Note 4 for additional information. &lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&lt;strong&gt;&lt;em&gt;Stock-Based Compensation&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;The stock-based compensation expense incurred by Lightbridge for employees and directors in connection with its equity incentive plan is based on the employee model of ASC 718, and the fair value of the options is measured at the grant date. In accordance with ASU 2018-07, &lt;em&gt;Compensation &amp;#8211; Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting&lt;/em&gt;, options granted to our consultants are accounted for in the same manner as options issued to employees.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp; &lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;Awards with service-based vesting conditions only &amp;#8211; Expense recognized on a straight-line basis over the requisite service period of the award.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;Awards with performance-based vesting conditions &amp;#8211; Expense is not recognized until it is determined that it is probable the performance-based conditions will be met. When achievement of a performance-based condition is probable, a catch-up of expense is recorded as if the award had been vesting on a straight-line basis from the award date. The award will continue to be expensed on a straight-line over the requisite service period basis until a higher performance-based condition is met, if applicable.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;Awards with market-based vesting conditions &amp;#8211; Expense recognized on a straight-line basis over the requisite service period, which is the lesser of the derived service period or the explicit service period if one is present. However, if the market condition is satisfied prior to the end of the requisite service period, the Company accelerates all remaining expense to be recognized.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;Awards with both performance-based and market-based vesting conditions &amp;#8211; If an award vesting or exercisability is conditional upon the achievement of either a market condition or performance or service conditions, the requisite service period is generally the shortest of the explicit, implicit, and derived service period.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;The Company elected to use the Black-Scholes pricing model to determine the fair value of stock options on the measurement date of the grant for service-based vesting conditions and the Monte-Carlo valuation method for performance-based or market-based vesting conditions. Shares that are issued to officers on the exercise dates of the stock options may be issued net of the minimum statutory withholding requirements to be paid by the Company on behalf of the employees. As a result, the actual number of shares issued are fewer than the actual number of shares exercised under the stock option.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&lt;strong&gt;&lt;em&gt;Recent Accounting Pronouncements &amp;#8211; To Be Adopted &lt;/em&gt;&lt;/strong&gt;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;In August 2020, the FASB issued ASU 2020-06&lt;em&gt;, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity&amp;#8217;s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity&amp;#8217;s Own Equity&lt;/em&gt;. ASU 2020-06 will simplify the accounting for convertible instruments by reducing the number of accounting models for convertible debt instruments and convertible preferred stock. Limiting the accounting models will result in fewer embedded conversion features being separately recognized from the host contract as compared with current U.S. GAAP. Convertible instruments that continue to be subject to separation models are (1) those with embedded conversion features that are not clearly and closely related to the host contract, that meet the definition of a derivative, and that do not qualify for a scope exception from derivative accounting and (2) convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in capital. ASU 2020-06 also amends the guidance for the derivatives scope exception for contracts in an entity&amp;#8217;s own equity to reduce form-over-substance-based accounting conclusions. ASU 2020-06 will be effective July 1, 2024, for the Company. Early adoption is permitted, but no earlier than January 1, 2021, including interim periods within that year. Management is currently evaluating the effect of the adoption of ASU 2020-06 on the consolidated financial statements and footnote disclosures.&lt;/p&gt;&lt;/div&gt;</us-gaap:OrganizationConsolidationBasisOfPresentationBusinessDescriptionAndAccountingPoliciesTextBlock>

Diluted net income per share is computed using the weighted-average number of common shares and, if dilutive, potential common shares outstanding during the period. Potential common shares consist of the incremental common shares issuable upon the exercise of stock options, warrants and convertible preferred shares (see Note 6.

The scope of the project included experiment design for irradiation of Lightbridge metallic fuel material samples in the Advanced Test Reactor (ATR) at INL. On April 22, 2020, the Company entered into a Cooperative Research and Development Agreement (CRADA) with Battelle Energy Alliance, LLC, the operating contractor of INL, in collaboration with DOE. Signing the CRADA was the last step in the contracting process to formalize a voucher award from the GAIN program. The project commenced in the second quarter of 2020. The total project value was approximately $846,000, with three-quarters of this amount funded by DOE for the scope performed by INL and the remaining amount funded by Lightbridge, by providing in-kind services to the project. &lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;For the three months ended March 31, 2021, approximately $0.1 million of work was completed by INL that caused the DOE to incur payment obligations related to the GAIN voucher. This amount was recorded as grant income in Other Operating Income (Loss) line item of the condensed consolidated statement of operations and the corresponding amount as research and development expenses. The cumulative amount of $0.2 million was recorded from September 2020 to March, 2021. The Company completed a contract extension for the INL GAIN voucher in January 2021.

Sales of the Company&amp;#8217;s common stock through Stifel, if any, will be made by any method that is deemed to be an &amp;#8220;at-the-market&amp;#8221; equity offering as defined in Rule 415 promulgated under the Securities Act of 1933. On March 25, 2021, the Company filed a new shelf registration statement on Form S-3, registering the sale of up to $75 million of the Company&amp;#8217;s securities, which registration statement was declared effective on April 5, 2021. Due to the offering limitations currently applicable to the Company under General Instruction I.B.6. of Form S-3 and the Company&amp;#8217;s public float as of April 8, 2021, and in accordance with the terms of the ATM Sales Agreement, the Company may offer and sell shares of its common stock having an aggregate offering price of up to $9,000,000 by the filing of a prospectus supplement on April 9, 2021. &lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;The Company records its ATM sales on a settlement date basis. No ATM sales occurred during the three months ended March 31, 2021. The Company sold 0.1 million shares under the ATM for the three months ended March 31, 2020 resulting in net proceeds of approximately $0.4 million.&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;&lt;strong&gt;Preferred Stock Equity Offerings&lt;/strong&gt;&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;&lt;strong&gt;&lt;em&gt;Series B Preferred Stock - Securities Purchase Agreement&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;On January 30, 2018, the Company issued 2,666,667 shares of newly created Non-Voting Series B Convertible Preferred Stock (the &amp;#8220;Series B Preferred Stock&amp;#8221;) and associated warrants to purchase up to 55,555 shares of the Company&amp;#8217;s common stock to the several purchasers for approximately $4.0 million or approximately $1.50 per share of Series B Preferred Stock and associated warrant. Dividends accrue on the Series B Preferred Stock at the rate of 7% per year and will be paid in-kind through an increase in the liquidation preference per share. The liquidation preference, initially $1.50 per share of Series B Preferred Stock, is the base that is also used to determine the number of common shares into which the Series B Preferred Stock will convert as well as the calculation of the 7% dividend. Each share of Series B Preferred Stock is convertible at the option of the holder into such number of shares of the Company&amp;#8217;s common stock equal to the liquidation preference divided by the conversion price of $18 per share subject to adjustments in the case of stock splits and stock dividends.&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;&amp;nbsp;&amp;nbsp; &lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;Holders of the Series B Preferred Stock are also entitled to participating dividends whenever dividends in cash, securities (other than shares of the Company&amp;#8217;s common stock paid on shares of common stock) or property are paid on common shares or shares of Series A Preferred Stock (as defined below). The amount of the dividends will equal the amount to which the holder would be entitled if all shares of Series B Preferred Stock had been converted to common stock immediately prior to the record date.&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;The holders of the Series B Preferred Stock have no voting rights. In addition, as long as the shares of Series B Preferred Stock are outstanding, the Company may not take certain actions without first having obtained the affirmative vote or waiver of the holders of a majority of the outstanding shares of Series B Preferred Stock. The Company has the option at any time after August 2, 2019 to redeem some or all of the outstanding Series B Preferred Stock for an amount in cash equal to the liquidation preference plus the amount of any accrued but unpaid dividends of the Series B Preferred Stock being redeemed. The holders of the Series B Preferred Stock do not have the ability to require the Company to redeem the Series B Preferred Stock. &lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;The Company has not redeemed any of the outstanding Series B Preferred Stock during the three months ended March 31, 2021 and 2020 and from the date of issuance.&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;The Company has the option of forcing the conversion of all or part of the Series B Preferred Stock if at any time the average closing price of the Company&amp;#8217;s common stock for a thirty-trading day period is greater than $65.88 prior to August 2, 2019 or greater than $98.82 at any time. The Company can exercise this option only if it also requires the conversion of the Series A Preferred Stock in the same proportion as it is requiring of the Series B Preferred Stock. The Company did not force the conversion of any of the outstanding Series B Preferred Stock during the three months ended March 31, 2021 and 2020.&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;Of the $4.0 million proceeds, approximately $0.3 million was allocated to the warrants with the remaining $3.7 million allocated to the Series B Preferred Stock. The Series B Preferred Stock was initially convertible into 2,666,667 shares of common stock (now convertible into 222,222 shares of common stock when adjusted for the one-for-twelve reverse stock split on October 21, 2019). The average of the high and low market prices of the common stock on January 30, 2018, the date of the closing of the sale of the preferred stock, was approximately $28.08 per share. At $28.08 per share the common stock into which the Series B Preferred Stock was initially convertible was valued at approximately $6.2 million. This amount was compared to the $3.7 million (rounded) of proceeds allocated to the Series B Preferred Stock to indicate that a beneficial conversion feature (&amp;#8220;BCF&amp;#8221;) of approximately $2.6 million existed at the date of issuance, which was immediately accreted as a deemed dividend because the conversion rights were immediately effective. &lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;Additionally, comparison of the original $1.50 conversion price prior to the one-for-twelve reverse stock split on October 21, 2019 of the PIK dividends to the $2.34 commitment date fair value per share on January 30, 2018 indicates that each PIK dividend will accrete $0.84 of BCF as an additional deemed dividend for every $1.50 of PIK dividend accrued. Total deemed dividends for this PIK dividend for the three months ended March 31, 2021 and 2020 were approximately $48,000 and $45,000, respectively. &lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;&amp;nbsp;&amp;nbsp; &lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;The accumulated PIK dividends (unpaid) at March 31, 2021 and December 31, 2020 were approximately $1.0 million and $0.9 million, respectively. The Series B Preferred Shares outstanding as of March 31, 2021 and December 31, 2020 was 2,666,667 shares with an aggregate liquidation preference of approximately $5.0 million and $4.9 million, including the accumulated dividends at March 31, 2021 and December 31, 2020, respectively.&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;&lt;strong&gt;&lt;em&gt;Series A Preferred Stock - Securities Purchase Agreement&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;On August 2, 2016, the Company issued 1,020,000 shares of newly created Non-Voting Series A Convertible Preferred Stock (the &amp;#8220;Series A Preferred Stock&amp;#8221;) to General International Holdings, Inc. for $2.8 million or approximately $2.75 per share. Dividends accrue on the Series A Preferred Stock at the rate of 7% per year and will be paid in-kind through an increase in the liquidation preference per share. The liquidation preference, initially $2.7451 per share of Series A Preferred Stock, is the base that is also used to determine the number of common shares into which the Series A Preferred Stock will convert as well as the calculation of the 7% dividend. Each share of Series A Preferred Stock is convertible at the option of the holder into such number of shares of the Company&amp;#8217;s common stock equal to the liquidation preference divided by the conversion price of $32.94 per share subject to adjustments in the case of stock splits and stock dividends.&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;Holders of the Series A Preferred Stock are also entitled to participating dividends whenever dividends in cash, securities (other than shares of the Company&amp;#8217;s common stock) or property are paid on common shares. The amount of the dividends is the amount to which the holder would be entitled if all shares of Series A Preferred Stock had been converted to common stock immediately prior to the record date.&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;The Company has the option of forcing the conversion of the Series A Preferred Stock if the trading price for the Company&amp;#8217;s common stock is more than two times the applicable conversion price (approximately $32.94 per share) before August 2, 2019, or if the trading price is more than three times the applicable conversion price. The Company has not forced the conversion of any of the outstanding Series A Preferred Stock during the three months ended March 31, 2021 and 2020 and from the date of issuance.&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;The Series A Preferred Stock was initially convertible into 1,020,000 shares of common stock (now convertible into 85,000 common shares when adjusted for the one-for-twelve reverse stock split on October 21, 2019). The average of the high and low market prices of the common stock on August 6, 2016, the date of the closing of the sale of the Series A Preferred Stock, was approximately $39.78 per share. At $39.78 per share the common stock into which the Series A Preferred Stock was initially convertible was valued at approximately $3.4 million. This amount was compared to the $2.8 million of proceeds of the Series A Preferred Stock to indicate that a BCF of approximately $0.6 million existed at the date of issuance in 2016, which was immediately accreted as a deemed dividend because the conversion rights were immediately effective.&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;Additionally, comparison of the $2.7451, original conversion price of the PIK dividends prior to the one-for-twelve reverse stock split on October 21, 2019, to the $3.315 commitment date fair value per share indicates that each PIK dividend will accrete $0.5699 of BCF as an additional deemed dividend for every $2.7451 of PIK dividend accrued. Total deemed dividends for this PIK dividend for the three months ended March 31, 2021 and 2020 were approximately $9,000 and $10,000, respectively.&lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;&amp;nbsp;&amp;nbsp; &lt;/p&gt; &lt;p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px"&gt;The holders of the Series A Preferred Stock have no voting rights. In addition, as long as 255,000 shares of Series A Preferred Stock are outstanding, the Company may not take certain actions without first having obtained the affirmative vote or waiver of the holders of a majority of the outstanding shares of Series A Preferred Stock. The Company has the option at any time after August 2, 2019 to redeem some or all of the outstanding Series A Preferred Stock for an amount in cash equal to the liquidation preference plus the amount of any accrued but unpaid dividends of the Series A Preferred Stock being redeemed.

On September 29, 2009, the Company changed its name from Thorium Power, Ltd. to Lightbridge Corporation and began its focus on developing and commercializing metallic nuclear fuels. The Company is a nuclear fuel technology company developing and working to commercialize it next generation nuclear fuel technology.&lt;/p&gt;&lt;/div&gt;</us-gaap:BasisOfPresentationAndSignificantAccountingPoliciesTextBlock>
  <us-gaap:SubstantialDoubtAboutGoingConcernTextBlock contextRef="From2021-01-01to2021-03-31">&lt;div style="TEXT-ALIGN: justify; FONT: 10pt TIMES NEW ROMAN"&gt;&lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;While the Company&amp;#8217;s cash at March 31, 2021 exceeds its currently budgeted expenditures through the first quarter of 2022, there are inherent uncertainties in forecasting future expenditures, especially forecasting for uncertainties such as future research and development (R&amp;amp;D) costs and how the COVID-19 outbreak may affect future costs and operations. Also, the cash requirements of the Company&amp;#8217;s future planned operations to commercialize its nuclear fuel, including any additional expenditures that may result from unexpected developments, requires it to raise significant additional capital including receiving government support. The Company will need to seek its shareholders&amp;#8217; approval in 2021 to increase the number of its authorized common shares for future equity financings, in order for the Company to continue to fund its future operations. Taking into account these uncertainties as well as the updated projected fuel development timeline of 15-20 years to commercialization, projected operational costs to keep the fuel development project on schedule and the various risks of developing and commercializing its nuclear fuel, these factors raise substantial doubt about the Company&amp;#8217;s ability to continue as a going concern for the 12 months following the date of this filing. To the extent any uncertainties reduce the Company&amp;#8217;s liquidity for the next 12 months, the Company will consider, if available, additional debt or equity raises and delaying certain expenditures, including delaying R&amp;amp;D expenses, until sufficient capital becomes available.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp; &lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;At March 31, 2021, the Company had approximately $15.2 million in cash and had a working capital surplus of approximately $15.2 million. The Company&amp;#8217;s net cash used in operating activities for the three months ended March 31, 2021 was approximately $6.3 million, and current projections indicate that the Company will have continued negative cash flows for the foreseeable future. Net losses incurred for the three months ended March 31, 2021 and 2020 amounted to approximately $(2.0) million and $(2.3) million, respectively. As of March 31, 2021, the Company had an accumulated deficit of approximately $131.2 million, representative of recurring losses since inception. The Company had incurred recurring losses since inception and it will continue to incur losses because it is in the early development stage of commercializing its nuclear fuel. &lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;The Company&amp;#8217;s plans to fund future operations include: (1) raising additional capital through future equity issuances or convertible debt financings; (2) additional funding through new relationships to help fund future R&amp;amp;D costs; and (3) seeking other sources of capital. The Company may issue securities, including common stock, preferred stock, and stock purchase contracts through private placement transactions or registered public offerings, pursuant to future registration statements. The current Form S-3 was filed with the SEC on March 25, 2021 registering the sale of up to $75 million of the Company&amp;#8217;s securities and declared effective on April 5, 2021. There can be no assurance as to the future availability of equity capital or the acceptability of the terms upon which financing and capital might become available. The Company&amp;#8217;s future liquidity needs to develop its nuclear fuel are long-term, and the ability to address those needs, and the ability to raise capital will largely be determined by the success of the development of its nuclear fuel, key nuclear development and government regulatory events, and its business decisions in the future.&lt;/p&gt;&lt;/div&gt;</us-gaap:SubstantialDoubtAboutGoingConcernTextBlock>

Also, the success of the Company&amp;#8217;s operations will be subject to other numerous contingencies, some of which are beyond management&amp;#8217;s control. These contingencies include general and regional economic conditions, contingent liabilities, potential competition with other nuclear fuel developers, including those entities developing accident tolerant fuels, changes in government regulations, support for nuclear power, changes in accounting and taxation standards, inability to achieve overall long-term goals, future impairment charges to its assets, and global or regional catastrophic events.

In March 2020, the WHO classified the COVID-19 outbreak a pandemic, based on increase in exposure globally. The current spread of COVID-19 that is impacting global economic activity and market conditions could lead to adverse changes in the Company&amp;#8217;s ability to conduct R&amp;amp;D activities with the United States national labs and others. The COVID-19 outbreak has impacted our business operations and results of operations for 2020, resulting in the reduction of R&amp;amp;D expenses and an increase in general and administrative expenses due to severance payments to former employees. However, the effects of the pandemic are fluid and changing rapidly, including with respect to vaccine and treatment developments and deployment and potential mutations of COVID-19. While the Company continues to monitor the impact of COVID-19 on its business, the Company is unable to accurately predict the ultimate impact on the results of operations, financial condition and liquidity that COVID-19 will have due to various uncertainties, including the geographic spread of the virus, the severity of the disease, the duration of the outbreak, and actions that may be taken by governmental authorities and other third-parties.&lt;/p&gt;&lt;/div&gt;</us-gaap:ConcentrationRiskCreditRisk>

Additionally, the Company concluded that the grant met the definition of a contribution and the grant is a non-reciprocal transaction. The Company determined that Subtopic 958-605, Not-for-Profit-Entities-Revenue Recognition did not apply, as the Company is a business entity and the grant is received from governmental agencies.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;In the absence of applicable guidance under U.S. generally accepted accounting principles (&amp;#8220;U.S. GAAP&amp;#8221;), the Company&amp;#8217;s management developed a policy to recognize grant income at the time the related costs are incurred and the right to payment is realized.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;The Company believes this policy is consistent with the overarching premise in ASC Topic 606, to ensure that revenue recognition reflects the transfer of promised goods or services to customers in an amount that reflects the consideration that we expect to be entitled to in exchange for those goods or services, even though there is no exchange as defined in ASC Topic 606. Additionally, the Company determined that the recognition of grant income as costs are incurred and amounts become realizable is analogous to the concept of transfer of control of a service over time under ASC Topic 606.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;Further, the Company believes that showing grant income on a gross method, with the grant income shown as other operating income and the related costs as a charge to R&amp;amp;D expense, rather than depicting the grant income as a reduction of R&amp;amp;D expense, is a more meaningful presentation. &lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;The Company recognized grant income of approximately $0.1 million and $0 for the three months ended March 31, 2021 and 2020, respectively.&lt;/p&gt;&lt;/div&gt;</us-gaap:ComprehensiveIncomePolicyPolicyTextBlock>

Costs, such as filing fees with patent granting agencies and legal fees directly relating to those filings, incurred to file patent applications were capitalized when the Company believed that there was a high likelihood that the patent would be issued and there would be future economic benefit associated with the patent. These costs were amortized from the date of the patent application on a straight-line basis over the estimated useful life of 20 years, which is the legal life of the patent. All costs associated with abandoned patent applications were expensed. The Company expensed patent annuity fees as these fees were maintenance fees required by the patent office at certain points in time after a patent was granted in order to keep the patent legal rights in force. During the years ended December 31, 2020 and 2019, these patent annuity fees were insignificant. In the fourth quarter of 2020, the remaining patent costs were written-off as impaired.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;Beginning January 1, 2021, patent filing fees with patent granting agencies and legal fees directly relating to those filings, incurred to file patent applications were expensed as the Company believes that there is not a high likelihood that there will be a future economic benefit associated with the patents, due to the uncertainties in the current fuel development timelines and the patents being commercialized. The Company continues to expense patent annuity fees as these fees are maintenance fees required by the patent office at certain points in time after a patent is granted, in order to keep the patent legal rights in force. As of March 31, 2021, and December 31, 2020 the carrying value of the patents on the balance sheets was $0.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;Costs for filing and legal fees for trademark applications are capitalized. Trademarks are considered intangible assets with an indefinite useful life and therefore should not be amortized. The Company performed an impairment test in the fourth quarter of 2020 and 2019 and no impairment of the trademarks was identified. As of March 31, 2021 and December 31, 2020, the carrying value of trademarks was approximately $0.1 million for both balance sheet dates.&lt;/p&gt;&lt;/div&gt;</us-gaap:LegalCostsPolicyTextBlock>

Leases with an initial term of 12 months or less are not recorded on the consolidated balance sheet in accordance with the short-term lease recognition exemption. The Company applies the practical expedient to non-separate and non-lease components for all leases that qualify. Lease expense is recognized on a straight-line basis over the lease term. The Company has only one lease for office rent and the lease is for a term of 12 months without renewal options. See Note 4 for additional information.&lt;/p&gt;&lt;/div&gt;</ltbr:Leases>

When achievement of a performance-based condition is probable, a catch-up of expense is recorded as if the award had been vesting on a straight-line basis from the award date. The award will continue to be expensed on a straight-line over the requisite service period basis until a higher performance-based condition is met, if applicable.&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;&amp;nbsp;&lt;/p&gt; &lt;p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"&gt;Awards with market-based vesting conditions &amp;#8211; Expense recognized on a straight-line basis over the requisite service period, which is the lesser of the derived service period or the explicit service period if one is present.

ASU 2020-06 will simplify the accounting for convertible instruments by reducing the number of accounting models for convertible debt instruments and convertible preferred stock. Limiting the accounting models will result in fewer embedded conversion features being separately recognized from the host contract as compared with current U.S. GAAP. Convertible instruments that continue to be subject to separation models are (1) those with embedded conversion features that are not clearly and closely related to the host contract, that meet the definition of a derivative, and that do not qualify for a scope exception from derivative accounting and (2) convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in capital. ASU 2020-06 also amends the guidance for the derivatives scope exception for contracts in an entity&amp;#8217;s own equity to reduce form-over-substance-based accounting conclusions. ASU 2020-06 will be effective July 1, 2024, for the Company. Early adoption is permitted, but no earlier than January 1, 2021, including interim periods within that year. Management is currently evaluating the effect of the adoption of ASU 2020-06 on the consolidated financial statements and footnote disclosures.&lt;/p&gt;&lt;/div&gt;</ltbr:RecentAccountingPronouncementsToBeAdopted>

Certain information and note disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America, including a summary of the Company&#8217;s significant accounting policies, have been condensed or omitted from these statements pursuant to such rules and regulations and, accordingly, they do not include all the information and notes necessary for comprehensive consolidated financial statements and should be read in conjunction with our audited consolidated financial statements for the year ended December 31, 2020, included in our Annual Report on Form 10-K for the year ended December 31, 2020.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">In the opinion of the management of the Company, all adjustments, which are of a normal recurring nature, necessary for a fair statement of the results for the three-month period have been made. Results for the interim period presented are not necessarily indicative of the results that might be expected for the entire fiscal year. When used in these notes, the terms &#8220;Lightbridge&#8221;, &#8220;Company,&#8221; &#8220;we,&#8221; &#8220;us&#8221; or &#8220;our&#8221; mean Lightbridge Corporation and all entities included in our condensed consolidated financial statements.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The Company was formed on October 6, 2006, when Thorium Power, Ltd., which was incorporated in the state of Nevada on February 2, 1999, merged with Thorium Power, Inc. (&#8220;TPI&#8221;), which was incorporated in the state of Delaware on January 8, 1992 (subsequently and collectively referred to as &#8220;we&#8221; or the &#8220;Company&#8221;). On September 29, 2009, the Company changed its name from Thorium Power, Ltd. to Lightbridge Corporation and began its focus on developing and commercializing metallic nuclear fuels. The Company is a nuclear fuel technology company developing and working to commercialize it next generation nuclear fuel technology.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong><em>Going Concern, Liquidity and Management&#8217;s Plan</em></strong></p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">While the Company&#8217;s cash at March 31, 2021 exceeds its currently budgeted expenditures through the first quarter of 2022, there are inherent uncertainties in forecasting future expenditures, especially forecasting for uncertainties such as future research and development (R&amp;D) costs and how the COVID-19 outbreak may affect future costs and operations. Also, the cash requirements of the Company&#8217;s future planned operations to commercialize its nuclear fuel, including any additional expenditures that may result from unexpected developments, requires it to raise significant additional capital including receiving government support. The Company will need to seek its shareholders&#8217; approval in 2021 to increase the number of its authorized common shares for future equity financings, in order for the Company to continue to fund its future operations. Taking into account these uncertainties as well as the updated projected fuel development timeline of 15-20 years to commercialization, projected operational costs to keep the fuel development project on schedule and the various risks of developing and commercializing its nuclear fuel, these factors raise substantial doubt about the Company&#8217;s ability to continue as a going concern for the 12 months following the date of this filing. To the extent any uncertainties reduce the Company&#8217;s liquidity for the next 12 months, the Company will consider, if available, additional debt or equity raises and delaying certain expenditures, including delaying R&amp;D expenses, until sufficient capital becomes available.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;&nbsp; </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">At March 31, 2021, the Company had approximately $15.2 million in cash and had a working capital surplus of approximately $15.2 million. The Company&#8217;s net cash used in operating activities for the three months ended March 31, 2021 was approximately $6.3 million, and current projections indicate that the Company will have continued negative cash flows for the foreseeable future. Net losses incurred for the three months ended March 31, 2021 and 2020 amounted to approximately $(2.0) million and $(2.3) million, respectively. As of March 31, 2021, the Company had an accumulated deficit of approximately $131.2 million, representative of recurring losses since inception. The Company had incurred recurring losses since inception and it will continue to incur losses because it is in the early development stage of commercializing its nuclear fuel. </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The Company&#8217;s plans to fund future operations include: (1) raising additional capital through future equity issuances or convertible debt financings; (2) additional funding through new relationships to help fund future R&amp;D costs; and (3) seeking other sources of capital. The Company may issue securities, including common stock, preferred stock, and stock purchase contracts through private placement transactions or registered public offerings, pursuant to future registration statements. The current Form S-3 was filed with the SEC on March 25, 2021 registering the sale of up to $75 million of the Company&#8217;s securities and declared effective on April 5, 2021. There can be no assurance as to the future availability of equity capital or the acceptability of the terms upon which financing and capital might become available. The Company&#8217;s future liquidity needs to develop its nuclear fuel are long-term, and the ability to address those needs, and the ability to raise capital will largely be determined by the success of the development of its nuclear fuel, key nuclear development and government regulatory events, and its business decisions in the future. </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong><em>Basis of Consolidation</em></strong></p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">These condensed consolidated financial statements include the accounts of Lightbridge, a Nevada corporation, and the Company&#8217;s wholly-owned subsidiaries, TPI, a Delaware corporation, and Lightbridge International Holding LLC, a Delaware limited liability company. These wholly-owned subsidiaries are inactive. All significant intercompany transactions and balances have been eliminated in consolidation. </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong><em>Certain Risks, Uncertainties and Concentrations</em></strong></p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The Company will need additional funding by way of a combination of strategic alliances, government grants, further offerings of equity securities, or an offering of debt securities in order to support its future R&amp;D activities required to further enhance and complete the development of its fuel products to a proof of concept and a commercial stage.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">There can be no assurance that the Company will be able to successfully continue to conduct its operations if there is a lack of financial resources available in the future to continue its fuel development, and a failure to do so would have a material adverse effect on the Company&#8217;s future R&amp;D activities, financial position, results of operations, and cash flows. Also, the success of the Company&#8217;s operations will be subject to other numerous contingencies, some of which are beyond management&#8217;s control. These contingencies include general and regional economic conditions, contingent liabilities, potential competition with other nuclear fuel developers, including those entities developing accident tolerant fuels, changes in government regulations, support for nuclear power, changes in accounting and taxation standards, inability to achieve overall long-term goals, future impairment charges to its assets, and global or regional catastrophic events. The Company may also be subject to various additional political, economic, and other uncertainties.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;&nbsp; </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">On January 30, 2020, the World Health Organization (&#8220;WHO&#8221;) announced a global health emergency because of a new strain of coronavirus originating in Wuhan, China (the &#8220;COVID-19 outbreak&#8221;) and the risk to the international community as the virus spreads globally beyond its point of origin. In March 2020, the WHO classified the COVID-19 outbreak a pandemic, based on increase in exposure globally. The current spread of COVID-19 that is impacting global economic activity and market conditions could lead to adverse changes in the Company&#8217;s ability to conduct R&amp;D activities with the United States national labs and others. The COVID-19 outbreak has impacted our business operations and results of operations for 2020, resulting in the reduction of R&amp;D expenses and an increase in general and administrative expenses due to severance payments to former employees. However, the effects of the pandemic are fluid and changing rapidly, including with respect to vaccine and treatment developments and deployment and potential mutations of COVID-19. While the Company continues to monitor the impact of COVID-19 on its business, the Company is unable to accurately predict the ultimate impact on the results of operations, financial condition and liquidity that COVID-19 will have due to various uncertainties, including the geographic spread of the virus, the severity of the disease, the duration of the outbreak, and actions that may be taken by governmental authorities and other third-parties. </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong><em>Grant Income </em></strong></p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The Company concluded that its government grant was not within the scope of ASC Topic 606 as it did not meet the definition of a contract with a customer. Additionally, the Company concluded that the grant met the definition of a contribution and the grant is a non-reciprocal transaction. The Company determined that Subtopic 958-605, Not-for-Profit-Entities-Revenue Recognition did not apply, as the Company is a business entity and the grant is received from governmental agencies.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">In the absence of applicable guidance under U.S. generally accepted accounting principles (&#8220;U.S. GAAP&#8221;), the Company&#8217;s management developed a policy to recognize grant income at the time the related costs are incurred and the right to payment is realized.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The Company believes this policy is consistent with the overarching premise in ASC Topic 606, to ensure that revenue recognition reflects the transfer of promised goods or services to customers in an amount that reflects the consideration that we expect to be entitled to in exchange for those goods or services, even though there is no exchange as defined in ASC Topic 606. Additionally, the Company determined that the recognition of grant income as costs are incurred and amounts become realizable is analogous to the concept of transfer of control of a service over time under ASC Topic 606.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Further, the Company believes that showing grant income on a gross method, with the grant income shown as other operating income and the related costs as a charge to R&amp;D expense, rather than depicting the grant income as a reduction of R&amp;D expense, is a more meaningful presentation. </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The Company recognized grant income of approximately $0.1 million and $0 for the three months ended March 31, 2021 and 2020, respectively.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;&nbsp; </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong>Patents and Trademarks</strong></p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Through September 30, 2020, patents were stated on the consolidated balance sheets at cost. Costs, such as filing fees with patent granting agencies and legal fees directly relating to those filings, incurred to file patent applications were capitalized when the Company believed that there was a high likelihood that the patent would be issued and there would be future economic benefit associated with the patent. These costs were amortized from the date of the patent application on a straight-line basis over the estimated useful life of 20 years, which is the legal life of the patent. All costs associated with abandoned patent applications were expensed. The Company expensed patent annuity fees as these fees were maintenance fees required by the patent office at certain points in time after a patent was granted in order to keep the patent legal rights in force. During the years ended December 31, 2020 and 2019, these patent annuity fees were insignificant. In the fourth quarter of 2020, the remaining patent costs were written-off as impaired.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Beginning January 1, 2021, patent filing fees with patent granting agencies and legal fees directly relating to those filings, incurred to file patent applications were expensed as the Company believes that there is not a high likelihood that there will be a future economic benefit associated with the patents, due to the uncertainties in the current fuel development timelines and the patents being commercialized. The Company continues to expense patent annuity fees as these fees are maintenance fees required by the patent office at certain points in time after a patent is granted, in order to keep the patent legal rights in force. As of March 31, 2021, and December 31, 2020 the carrying value of the patents on the balance sheets was $0.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Costs for filing and legal fees for trademark applications are capitalized. Trademarks are considered intangible assets with an indefinite useful life and therefore should not be amortized. The Company performed an impairment test in the fourth quarter of 2020 and 2019 and no impairment of the trademarks was identified. As of March 31, 2021 and December 31, 2020, the carrying value of trademarks was approximately $0.1 million for both balance sheet dates. </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong><em>Leases</em></strong></p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">In accordance with ASU 2016-02, <em>Leases (Topic 842)</em>, which requires recognition of most lease arrangements on the balance sheet, the Company recognizes operating lease right of use assets and liabilities at commencement date based on the present value of the future minimum lease payments over the lease term. Leases with an initial term of 12 months or less are not recorded on the consolidated balance sheet in accordance with the short-term lease recognition exemption. The Company applies the practical expedient to non-separate and non-lease components for all leases that qualify. Lease expense is recognized on a straight-line basis over the lease term. The Company has only one lease for office rent and the lease is for a term of 12 months without renewal options. See Note 4 for additional information. </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong><em>Stock-Based Compensation</em></strong></p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The stock-based compensation expense incurred by Lightbridge for employees and directors in connection with its equity incentive plan is based on the employee model of ASC 718, and the fair value of the options is measured at the grant date. In accordance with ASU 2018-07, <em>Compensation &#8211; Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting</em>, options granted to our consultants are accounted for in the same manner as options issued to employees.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp; </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Awards with service-based vesting conditions only &#8211; Expense recognized on a straight-line basis over the requisite service period of the award.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Awards with performance-based vesting conditions &#8211; Expense is not recognized until it is determined that it is probable the performance-based conditions will be met. When achievement of a performance-based condition is probable, a catch-up of expense is recorded as if the award had been vesting on a straight-line basis from the award date. The award will continue to be expensed on a straight-line over the requisite service period basis until a higher performance-based condition is met, if applicable.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Awards with market-based vesting conditions &#8211; Expense recognized on a straight-line basis over the requisite service period, which is the lesser of the derived service period or the explicit service period if one is present. However, if the market condition is satisfied prior to the end of the requisite service period, the Company accelerates all remaining expense to be recognized.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Awards with both performance-based and market-based vesting conditions &#8211; If an award vesting or exercisability is conditional upon the achievement of either a market condition or performance or service conditions, the requisite service period is generally the shortest of the explicit, implicit, and derived service period.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The Company elected to use the Black-Scholes pricing model to determine the fair value of stock options on the measurement date of the grant for service-based vesting conditions and the Monte-Carlo valuation method for performance-based or market-based vesting conditions. Shares that are issued to officers on the exercise dates of the stock options may be issued net of the minimum statutory withholding requirements to be paid by the Company on behalf of the employees. As a result, the actual number of shares issued are fewer than the actual number of shares exercised under the stock option.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;"><strong><em>Recent Accounting Pronouncements &#8211; To Be Adopted </em></strong></p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">In August 2020, the FASB issued ASU 2020-06<em>, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity&#8217;s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity&#8217;s Own Equity</em>. ASU 2020-06 will simplify the accounting for convertible instruments by reducing the number of accounting models for convertible debt instruments and convertible preferred stock. Limiting the accounting models will result in fewer embedded conversion features being separately recognized from the host contract as compared with current U.S. GAAP. Convertible instruments that continue to be subject to separation models are (1) those with embedded conversion features that are not clearly and closely related to the host contract, that meet the definition of a derivative, and that do not qualify for a scope exception from derivative accounting and (2) convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in capital. ASU 2020-06 also amends the guidance for the derivatives scope exception for contracts in an entity&#8217;s own equity to reduce form-over-substance-based accounting conclusions. ASU 2020-06 will be effective July 1, 2024, for the Company. Early adoption is permitted, but no earlier than January 1, 2021, including interim periods within that year. Management is currently evaluating the effect of the adoption of ASU 2020-06 on the consolidated financial statements and footnote disclosures.</p></div><span></span>

The scope of the project included experiment design for irradiation of Lightbridge metallic fuel material samples in the Advanced Test Reactor (ATR) at INL. On April 22, 2020, the Company entered into a Cooperative Research and Development Agreement (CRADA) with Battelle Energy Alliance, LLC, the operating contractor of INL, in collaboration with DOE. Signing the CRADA was the last step in the contracting process to formalize a voucher award from the GAIN program. The project commenced in the second quarter of 2020. The total project value was approximately $846,000, with three-quarters of this amount funded by DOE for the scope performed by INL and the remaining amount funded by Lightbridge, by providing in-kind services to the project. </p> <p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px">&nbsp;</p> <p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px">For the three months ended March 31, 2021, approximately $0.1 million of work was completed by INL that caused the DOE to incur payment obligations related to the GAIN voucher. This amount was recorded as grant income in Other Operating Income (Loss) line item of the condensed consolidated statement of operations and the corresponding amount as research and development expenses. The cumulative amount of $0.2 million was recorded from September 2020 to March, 2021. The Company completed a contract extension for the INL GAIN voucher in January 2021. The period of performance now runs through September 30, 2021.</p> <p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px">&nbsp;</p> <p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px">On March 25, 2021, the Company was awarded a second voucher from the DOE&#8217;s GAIN program to support development of Lightbridge Fuel&#8482; in collaboration with the Pacific Northwest National Laboratory (PNNL). The scope of the project is to demonstrate Lightbridge&#8217;s nuclear fuel casting process using depleted uranium, a key step in the manufacture of Lightbridge Fuel&#8482;. The project is anticipated to commence in the first half of 2021. The total project value is approximately $664,000, with three-quarters of this amount funded by DOE for the scope performed by PNNL.</p></div><span></span>

Dividends accrue on the Series B Preferred Stock at the rate of 7% per year and will be paid in-kind through an increase in the liquidation preference per share. The liquidation preference, initially $1.50 per share of Series B Preferred Stock, is the base that is also used to determine the number of common shares into which the Series B Preferred Stock will convert as well as the calculation of the 7% dividend. Each share of Series B Preferred Stock is convertible at the option of the holder into such number of shares of the Company&#8217;s common stock equal to the liquidation preference divided by the conversion price of $18 per share subject to adjustments in the case of stock splits and stock dividends.</p> <p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px">&nbsp;&nbsp; </p> <p style="font-size:10pt;font-family:times new roman;text-align:justify;margin:0px">Holders of the Series B Preferred Stock are also entitled to participating dividends whenever dividends in cash, securities (other than shares of the Company&#8217;s common stock paid on shares of common stock) or property are paid on common shares or shares of Series A Preferred Stock (as defined below).

The Company has the option at any time after August 2, 2019 to redeem some or all of the outstanding Series B Preferred Stock for an amount in cash equal to the liquidation preference plus the amount of any accrued but unpaid dividends of the Series B Preferred Stock being redeemed.

The Series B Preferred Stock was initially convertible into 2,666,667 shares of common stock (now convertible into 222,222 shares of common stock when adjusted for the one-for-twelve reverse stock split on October 21, 2019). The average of the high and low market prices of the common stock on January 30, 2018, the date of the closing of the sale of the preferred stock, was approximately $28.08 per share.

Also, the cash requirements of the Company&#8217;s future planned operations to commercialize its nuclear fuel, including any additional expenditures that may result from unexpected developments, requires it to raise significant additional capital including receiving government support. The Company will need to seek its shareholders&#8217; approval in 2021 to increase the number of its authorized common shares for future equity financings, in order for the Company to continue to fund its future operations. Taking into account these uncertainties as well as the updated projected fuel development timeline of 15-20 years to commercialization, projected operational costs to keep the fuel development project on schedule and the various risks of developing and commercializing its nuclear fuel, these factors raise substantial doubt about the Company&#8217;s ability to continue as a going concern for the 12 months following the date of this filing. To the extent any uncertainties reduce the Company&#8217;s liquidity for the next 12 months, the Company will consider, if available, additional debt or equity raises and delaying certain expenditures, including delaying R&amp;D expenses, until sufficient capital becomes available.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp; </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">At March 31, 2021, the Company had approximately $15.2 million in cash and had a working capital surplus of approximately $15.2 million. The Company&#8217;s net cash used in operating activities for the three months ended March 31, 2021 was approximately $6.3 million, and current projections indicate that the Company will have continued negative cash flows for the foreseeable future. Net losses incurred for the three months ended March 31, 2021 and 2020 amounted to approximately $(2.0) million and $(2.3) million, respectively. As of March 31, 2021, the Company had an accumulated deficit of approximately $131.2 million, representative of recurring losses since inception. The Company had incurred recurring losses since inception and it will continue to incur losses because it is in the early development stage of commercializing its nuclear fuel. </p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The Company&#8217;s plans to fund future operations include: (1) raising additional capital through future equity issuances or convertible debt financings; (2) additional funding through new relationships to help fund future R&amp;D costs; and (3) seeking other sources of capital. The Company may issue securities, including common stock, preferred stock, and stock purchase contracts through private placement transactions or registered public offerings, pursuant to future registration statements. The current Form S-3 was filed with the SEC on March 25, 2021 registering the sale of up to $75 million of the Company&#8217;s securities and declared effective on April 5, 2021. There can be no assurance as to the future availability of equity capital or the acceptability of the terms upon which financing and capital might become available. The Company&#8217;s future liquidity needs to develop its nuclear fuel are long-term, and the ability to address those needs, and the ability to raise capital will largely be determined by the success of the development of its nuclear fuel, key nuclear development and government regulatory events, and its business decisions in the future.</p></div><span></span>

In March 2020, the WHO classified the COVID-19 outbreak a pandemic, based on increase in exposure globally. The current spread of COVID-19 that is impacting global economic activity and market conditions could lead to adverse changes in the Company&#8217;s ability to conduct R&amp;D activities with the United States national labs and others. The COVID-19 outbreak has impacted our business operations and results of operations for 2020, resulting in the reduction of R&amp;D expenses and an increase in general and administrative expenses due to severance payments to former employees. However, the effects of the pandemic are fluid and changing rapidly, including with respect to vaccine and treatment developments and deployment and potential mutations of COVID-19. While the Company continues to monitor the impact of COVID-19 on its business, the Company is unable to accurately predict the ultimate impact on the results of operations, financial condition and liquidity that COVID-19 will have due to various uncertainties, including the geographic spread of the virus, the severity of the disease, the duration of the outbreak, and actions that may be taken by governmental authorities and other third-parties.</p></div><span></span>

These costs were amortized from the date of the patent application on a straight-line basis over the estimated useful life of 20 years, which is the legal life of the patent. All costs associated with abandoned patent applications were expensed. The Company expensed patent annuity fees as these fees were maintenance fees required by the patent office at certain points in time after a patent was granted in order to keep the patent legal rights in force. During the years ended December 31, 2020 and 2019, these patent annuity fees were insignificant.

However, if the market condition is satisfied prior to the end of the requisite service period, the Company accelerates all remaining expense to be recognized.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">Awards with both performance-based and market-based vesting conditions &#8211; If an award vesting or exercisability is conditional upon the achievement of either a market condition or performance or service conditions, the requisite service period is generally the shortest of the explicit, implicit, and derived service period.</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">&nbsp;</p> <p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">The Company elected to use the Black-Scholes pricing model to determine the fair value of stock options on the measurement date of the grant for service-based vesting conditions and the Monte-Carlo valuation method for performance-based or market-based vesting conditions. Shares that are issued to officers on the exercise dates of the stock options may be issued net of the minimum statutory withholding requirements to be paid by the Company on behalf of the employees. As a result, the actual number of shares issued are fewer than the actual number of shares exercised under the stock option.</p></div><span></span>

<td class="text"><div style="TEXT-ALIGN: justify; FONT: 10pt TIMES NEW ROMAN"><p style="FONT-SIZE: 10pt; FONT-FAMILY: times new roman; MARGIN: 0px; text-align:justify;">In August 2020, the FASB issued ASU 2020-06<em>, Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity&#8217;s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity&#8217;s Own Equity</em>. ASU 2020-06 will simplify the accounting for convertible instruments by reducing the number of accounting models for convertible debt instruments and convertible preferred stock. Limiting the accounting models will result in fewer embedded conversion features being separately recognized from the host contract as compared with current U.S. GAAP. Convertible instruments that continue to be subject to separation models are (1) those with embedded conversion features that are not clearly and closely related to the host contract, that meet the definition of a derivative, and that do not qualify for a scope exception from derivative accounting and (2) convertible debt instruments issued with substantial premiums for which the premiums are recorded as paid-in capital. ASU 2020-06 also amends the guidance for the derivatives scope exception for contracts in an entity&#8217;s own equity to reduce form-over-substance-based accounting conclusions. ASU 2020-06 will be effective July 1, 2024, for the Company. Early adoption is permitted, but no earlier than January 1, 2021, including interim periods within that year. Management is currently evaluating the effect of the adoption of ASU 2020-06 on the consolidated financial statements and footnote disclosures.</p></div><span></span>

Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.</p></div>
