Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

(e) On August 28, 2025, the Board of Directors (the “Board”) of Lightbridge Corporation (the “Company”), pursuant to the recommendation of the Compensation Committee of the Board, approved the grant of restricted shares of the Company’s common stock (the “RSA Grants”) to certain executive officers, employees and consultants of the Company as well as members of the Board under the Company’s 2020 Omnibus Incentive Plan. On August 28, 2025, the Board also approved the form of Performance-Based Restricted Stock Agreement to be entered into in connection with the RSA Grants, a copy of which is attached hereto as Exhibit 10.1.

The RSA Grants are subject to vesting as follows:

	·	Twenty-five percent (25%) of each RSA Grant is service-based and will vest in three equal annual installments beginning on the first anniversary of the grant date, contingent on the grantee’s continued service with the Company on each applicable vesting date; and

	·	Seventy-five percent (75%) of each RSA Grant is performance-based and will vest, if at all, based on the Company’s achievement of specified operational milestones, contingent on (1) achievement of the applicable milestone prior to expiration of the performance period on December 31, 2028 (the “Performance Period”) and certification of its achievement by the Compensation Committee of the Board no later than March 31, 2029 and (2) the grantee’s continued service with the Company on each applicable milestone certification date.

The operational milestones applicable to vesting of the performance-based RSA Grants are designed to be reasonably difficult to achieve and relate to key Company objectives for the Performance Period. The portion of each RSA Grant that is performance-based vests, if at all, as follows: 25% on specified manufacturing goals, 25% on specified goals related to the design and construction of a new fuel facility, 15% on specified commercial objectives, and 10% on specified funding goals.

Any shares of the performance-based RSA Grants that remain unvested as of the end of the Performance Period will automatically be forfeited and cancelled without consideration.

The total number of shares of common stock underlying the RSA Grants to the Company’s principal executive officer, principal financial officer and named executive officers are as follows:

Name	Position	Total	Service-based	Performance-based
Seth Grae	Chairman and Chief Executive Officer	290,830	72,707	218,123
Andrey Mushakov	Executive Vice President, Nuclear Operations	181,389	45,347	136,042
