What changed: Q2 2026 10-Q of LanzaTech Global, Inc. (Nasdaq: LNZA), filed under AMCI Acquisition Corp. II's CIK. The cover states 13,089,163 shares of common stock outstanding as of August 10, 2026 for the quarterly period ended June 30, 2026. The forward-looking statements section identifies, among the matters it covers, the company's ability to continue operations as a going concern, its ability to raise substantial additional financing, maintenance of its Nasdaq listing, and remediation of material weaknesses in internal control over financial reporting. Why it matters: This summary is drawn from the cover page and the cautionary note of the report; the balance sheet and statements of operations are not covered here. LanzaTech's Q2 2026 figures are stated in the company's earnings release filed the same day (accession 0001628280-26-056930).

What changed: Exhibit 99.1 to an 8-K filed under AMCI Acquisition Corp. II's CIK: LanzaTech Global, Inc. (Nasdaq: LNZA) Q2 2026 results. Revenue was $9.0 million versus $9.1 million a year earlier; operating expenses fell 67% to $11.7 million from $35.1 million; net income was $184.3 million against a $32.5 million net loss, which the company attributes primarily to a non-cash unrealized gain on its investment in SGLT; adjusted EBITDA was $(7.6) million versus $(29.7) million. Why it matters: Reported net income is a mark-to-market gain on a listed stake, not cash earnings; adjusted EBITDA remains negative at $(7.6) million and revenue was flat year over year. The $115 million of annualized FLITE offtake revenue cited is a company estimate for a project that has not reached FID.
What changed: Item 5.07: LanzaTech Global, Inc. held its 2026 annual meeting of stockholders on June 23, 2026. A total of 7,865,074 shares of common stock, approximately 77.96% of the shares entitled to vote, were represented in person, by remote communication or by proxy. As of the close of business on the April 28, 2026 record date there were 10,089,163 shares of common stock issued and outstanding and entitled to vote. Stockholders voted on three proposals, each described in the definitive proxy statement filed with the SEC on April 29, 2026. Why it matters: Turnout of 77.96% is healthy and confirms a quorum, but the number that stands out is the share count: 10,089,163 shares outstanding at a company that came public through a SPAC, which points to a reverse split and a much-reduced equity base. For a holder that is the context for reading any per-share figure at this company. The filing lists three proposals without describing them here, so the substance of what was approved has to come from the April 29, 2026 proxy statement.

What changed: LanzaTech Global, Inc., the successor to AMCI Acquisition Corp. II, called its 2026 annual meeting for Tuesday, June 23, 2026, record date April 28, 2026, with 10,089,163 shares of common stock issued and outstanding and entitled to one vote each. Holders elect two Class III directors to terms expiring in 2029 and ratify BDO USA, P.C. for the fiscal year ending December 31, 2026. Why it matters: Two consecutive audit opinions carrying substantial-doubt going-concern language is the material fact - the company is asking holders to ratify an auditor that has twice qualified its viability. With only 10,089,163 shares outstanding, any rescue financing at these levels would dilute existing holders severely, and the AMCI trust that once backed the stock was released at the de-SPAC, so there is no cash floor beneath the equity.

Set by the filing that calls the meeting. Tender after it and the company is under no obligation to pay you the trust value.
