Amendment Description	This Form 10-Q/A is being filed as an amendment (“Amendment No. 1”) to the Quarterly Report on Form 10-Q filed by SAExploration Holdings, Inc., formerly known as Trio Merger Corp., with the Securities and Exchange Commission on August 28, 2013 (the “Original Filing”), to amend (i) Item 1 of Part I, “Financial Information,” (ii) Item 2 of Part I, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and (iii) Item 4 of Part I, “Controls and Procedures” in connection with the restatement of our interim financial statements as of and for the three and six months ended June 30, 2013, which were included in the Original Filing. The restatement is necessary to correct certain errors in accounting relating to the recognition of share-based compensation expense of our accounting predecessor and the improper capitalization of certain work-in-progress expenses attributable to our operations in Colombia and to adjust our income tax (benefit) provision for such corrections. This Amendment No. 1 also includes currently dated certifications of our Chief Executive Officer and Chief Financial Officer as Exhibits 31.1, 31.2, 32.1 and 32.2 and restated versions of our financial statements formatted in Extensible Business Reporting Language (XBRL) as Exhibit 101, and we have updated the Exhibit Index accordingly. Except as described above, no other sections of the Original Filing were affected; however, for the convenience of the reader, this Amendment No. 1 restates in its entirety, as amended, the Original Filing. This Amendment No. 1 is presented as of August 28, 2013, the filing date of the Original Filing, and has not been updated to reflect other events, other than those identified above related to the restatement, occurring after the date of the Original Filing, or to modify or update those disclosures affected by subsequent events. Without limiting the foregoing, this filing does not purport to update Management's Discussion and Analysis of Financial Condition and Results of Operations contained in the Original Filing for any information, uncertainties, transactions, risks, events or trends known to management occurring subsequent to the date of the Original Filing. More current information is contained in our other filings with the Securities and Exchange Commission[, including our Annual Report on Form 10-K for the year ended December 31, 2013.
