Amendment Description In this Quarterly Report on Form 10-Q/A (Amendment No.1) for the quarters ended March, 31, 2015 and 2014 (“Quarterly Report”), as originally filed with the Securities and Exchange Commission (the “SEC”) on May 7, 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 ended March 31, 2015 and March 31, 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 Report on Form 10-Q for the quarterly period ended June 30, 2015, as originally filed with the SEC on August 19, 2015. All amounts in this Quarterly Report affected by the restatement adjustments reflect such amounts as restated.
