Amendment Description	This Amendment No. 1 on Form 10-Q/A (“Amendment No. 1”) is being filed to amend and restate urban-gro, Inc.’s (together with its wholly owned subsidiaries, the “Company”) Quarterly Report on Form 10-Q for the three months ended March 31, 2024 (“Original Filing”), filed with the U.S. Securities and Exchange Commission (“SEC”) on April 30, 2024 (“Original Filing Date”). In filing this Amendment No. 1, we are restating our previously issued Consolidated Financial Statements as of and for the three months ended March 31, 2024 (the “Affected Period”) to account for certain adjustments discovered during the Company’s re-audit of its financial statements issued in Amendment No. 2 on Form 10-K/A for the fiscal year ended December 31, 2023. All material restatement information will be included in the Amended Reports, and we do not intend to separately amend other filings that we have previously filed with the SEC.Accordingly, investors and other readers should rely only on the financial information and other disclosures regarding the periods described above in this Amendment No. 1 and in any other future filings with the SEC (as applicable) and should not rely on any previously issued or filed reports, press releases, corporate presentations or similar communications relating to the periods described above.As required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Company’s principal executive officer and principal financial officer are providing new currently dated certifications required pursuant to Exchange Act Rules 13a-14(a) and 15d-14(a), as adopted pursuant Section 302 of the Sarbanes-Oxley Act of 2002, which are attached hereto.
