Amendment Description	This Amendment No. 2 on Form 10-K/A (the "10-K/A") to the Annual Report on Form 10-K for the year ended December 28, 2024 ("Original 10-K") of NV5 Global, Inc. (the "Company") is being filed with the Securities and Exchange Commission ("SEC") to provide certain additional information required by Item 12 of Part III of Form 10-K ("Beneficial Holder Information") inadvertently omitted from Amendment No. 1 to the Original 10-K filed on April 28, 2025 (“Amendment No. 1”). In addition, in order to comply with the technical requirements of Rule 12b-15 in connection with the filing of this Form 10-K/A, updated certifications under Section 302 of the Sarbanes-Oxley Act of 2002 are being filed with this Form 10-K/A. Because no financial statements are contained within this Form 10-K/A, we are not filing currently dated certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002. No changes have been made to the Original 10-K, as amended by Amendment No. 1, other than the addition of the Beneficial Holder Information, certain updating references, the inclusion of such certifications, and updates to the Exhibit Index. Except for the foregoing, this Form 10-K/A speaks as of the filing date of the Original 10-K, as amended by Amendment No. 1, and does not update or discuss any other Company developments after the respective dates of the Original 10-K or Amendment No.1.
