Why they said they were late

LanzaTech Global, Inc. (the “Company”) is filing this Notification of Late Filing on Form 12b-25 with respect to its Quarterly Report on Form 10-Q for its fiscal quarter ended September 30, 2025 (the “Form 10-Q”). As previously disclosed, the Company is streamlining its priorities to sharpen its business focus and improve its cost structure. As part of these initiatives, the Company has undertaken a reduction in force aimed at right-sizing its business, which has led to a reduction in the internal resources the Company has available to devote to the Form 10-Q preparation. As a result of its resource constraints, the Company needs additional time to finalize certain disclosures and to complete the work related to the Company’s financial reporting. Therefore, the Company will be unable to file the Form 10-Q within the prescribed time period without unreasonable effort or expense. The Company intends to file the Form 10-Q no later than the prescribed due date provided by Rule 12b-25 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). 2

2025-05-09filed late (10-Q)accounts not ready SEC →

LanzaTech Global, Inc. (the “Company”) is filing this Notification of Late Filing on Form 12b-25 with respect to its Quarterly Report on Form 10-Q for its fiscal quarter ended March 31, 2025 (the “Form 10-Q”). As previously disclosed, the Company is streamlining its priorities to sharpen its business focus and improve its cost structure, and as part of these initiatives, the Company has been evaluating various strategic options and potential transactions. On May 7, 2025, the Company entered into a Series A Convertible Senior Preferred Stock Purchase Agreement (the “Purchase Agreement”), pursuant to which on May 7, 2025, it issued 20,000,000 shares of its preferred stock designated as “Series A Convertible Senior Preferred Stock”, par value of $0.0001 per share (“Preferred Stock”), for an aggregate purchase price of $40,000,000 among other transactions. These ongoing processes, including negotiating the terms of the Purchase Agreement and related transactions, have required a significant amount of management’s time and other Company resources, certain of which would otherwise have been devoted to the Form 10-Q preparation. Additionally, the structure of the Preferred Stock and related transactions impacts the Company’s disclosures in its Form 10-Q. As a result of the increased workload associated with these efforts, including their impact on procedures and disclosures related to the Form 10-Q, the Company will be unable to file the Form 10-Q within the prescribed time period without unreasonable effort or expense. The Company intends to file the Form 10-Q no later than the prescribed due date provided by Rule 12b-25 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). 2

LanzaTech Global, Inc. (the “Company”) is filing this Notification of Late Filing on Form 12b-25 with respect to its Annual Report on Form 10-K for its fiscal year ended December 31, 2024 (the “Form 10-K”). As previously disclosed, the Company is streamlining its priorities to sharpen its business focus and improve its cost structure, and as part of these initiatives, the Company is evaluating various strategic options.

Additionally, the status and implementation of any such transaction would also impact the Company’s assessment of its financial position and liquidity and corresponding disclosures in its Form 10-K. As a result of the increased workload associated with these efforts, including their impact on procedures and disclosures related to finalizing the Form 10-K, the Company is unable to file the Form 10-K within the prescribed time period without unreasonable effort or expense. The Company intends to file the Form 10-K no later than the prescribed due date provided by Rule 12b-25 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). 2

2021-11-15filed late (10-Q)auditor SEC →

AMCI Acquisition Corp. II (the “Registrant”) has elected not to file its quarterly report on Form 10-Q for the fiscal quarter ended September 30, 2021 (the “Form 10-Q”) and is filing a Form 12b-25 for a 5 day extension deemed necessary for the following reason: As a result of recent guidance to Special Purpose Acquisition Companies by the SEC regarding redeemable equity instruments, the Registrant revisited its application of ASC 480-10-S99 on its financial statements. The Registrant had previously classified a portion of its shares of Class A common stock in permanent equity. In accordance with ASC 480-10-S99 and after discussion with the Registrant’s management, the Registrant’s audit committee concluded that all of its shares of Class A common stock should be classified as temporary equity. The Registrant is working diligently to complete the review of the financial statements for the three months ended September 30, 2021 as soon as possible; however, given the scope of the process for determining the appropriate treatment of the redeemable equity in accordance with ASC 480-10-S99, the Registrant is unable to complete and file the Q3 2021 Form 10-Q by the required due date of November 15, 2021 without unreasonable effort and expense. The Registrant expects to file such report by November 22, 2021

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.
