Amendment Description In this Quarterly Report on Form 10-Q/A (Amendment No.1) for the quarter ended June 30, 2015 (“Quarterly Report”), as originally filed with the Securities and Exchange Commission (the “SEC”) on August 14, 2015 (the “Original Report”), Lightbridge Corporation (“Lightbridge,” the “Company,” “we” or “us”) is restating its previously issued condensed consolidated financial statements and the related disclosures for the three months and six months ended June 30, 2015 and June 30, 2014 (collectively, the “Restated Periods”). As discussed in further detail below and in Note 2 to the accompanying condensed consolidated financial statements, the restatement is the result of a misapplication in the guidance on accounting for warrants. We assessed the impact of this misapplication on our prior interim and annual financial statements and concluded that the combined impact was material to these financial statements. Consequently, we have restated the prior period financial statements identified above. Concurrently with the filing of this Form 10-Q/A, the Company is also filing Amendment No. 1 on Form 10-Q/A to the Company’s Quarterly on Form 10-Q for the quarterly period ended March 31, 2015, as originally filed with the SEC on May 7, 2015. All amounts in this Quarterly Report affected by the restatement adjustments reflect such amounts as restated.
