Why they said they were late

MasTec, Inc. (“MasTec” or the “Company”) is filing this Notification of Late Filing on Form 12b-25 with respect to its Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (the “Form 10-K”). MasTec could not file the Form 10-K within the prescribed period because additional time was required to complete audit procedures related to a wholly-owned subsidiary of the Company. The Company anticipates that the Form 10-K will not result in changes to the financial results for the full year and fourth quarter of 2023, which results were announced in the Company’s press release dated February 29, 2024, and that the Form 10-K will be filed as soon as practicable on or before the 15th calendar day following the prescribed due date. As a result of these developments, the Company is unable, without unreasonable effort or expense, to timely file the Form 10-K

About this score

reportingrisk.com scores every active US filer on three things a company tells the SEC about itself: late-filing notices on Form NT, 8-K item 4.02 (past accounts declared unreliable) and 4.01 (auditor changes). 1,012 are flagged today.

Every score is frozen and checked twelve months later. Across 91,452 of them, a company scoring 4 or more ended that year delisted, bankrupt, restated or silent 17.2% of the time, against 4.0% for a clean record. Scores before 2026-09-27 were reconstructed from the filing history as it stood at each date, so the record is a backtest rather than years of live calls.

Every item above is a filing this company made with the SEC.
