Amendment Description ServiceTitan, Inc. (the “Company”) is filing this Amendment No. 1 on Form 10-Q/A (the “Amendment”) to its Quarterly Report on Form 10-Q for the quarter ended April 30, 2026, originally filed with the U.S. Securities and Exchange Commission (the “SEC”) on June 5, 2026 (the “Quarterly Report”), solely for the purpose of filing revised certifications by the Company’s principal executive officer and principal financial officer, as Exhibits 31.1 and 31.2 herewith, to correct an inadvertent omission of certain language regarding internal control over financial reporting required to be included in such certifications by Item 601(b)(31)(i) of Regulation S-K. In accordance with interpretation 246.13 in the Regulation S-K section of the SEC’s “Corporation Finance Interpretations,” this Amendment contains only the cover page, explanatory note, signature page and paragraphs 1, 2, 4 and 5 of each of the revised certifications filed as exhibits to this Amendment. Because no financial statements are included with this Amendment, paragraph 3 of each of the certifications has been omitted. Except as described above, no attempt has been made in this Amendment to modify or update the other disclosures or exhibits presented in the Quarterly Report. Except for Exhibits 31.1 and 31.2 filed herewith, this Amendment does not reflect events occurring after the filing of the Quarterly Report or modify or update those disclosures. Accordingly, this Amendment should be read in conjunction with the Quarterly Report and the Company’s other filings with the SEC.
