LanzaTech Global (LNZA) is a ≈$300M post-SPAC sustainable aviation fuel producer with disclosed going-concern issues and one analyst (Hold, $15 target). Up 41.6% in the trailing month. A specific governance signal surfaced from a Trinseo (TSEOF) 10-K/A filed April 27, 2026, points the opposite direction — and the base rate behind it is concrete.

What the filings say

The Trinseo 10-K/A added Part III governance disclosures, including the January 16, 2026 appointment of Carol Flaton (AlixPartners MD 2014-19, Lazard MD 2008-14) and Jill Frizzley (Weil Gotshal restructuring counsel) to the board. Neither received committee assignments. Both are documented restructuring specialists.

A cross-ticker audit of their 16 prior board appointments produced this base rate:

• 14/16 (87.5%) reached Chapter 11 while they served
• 15/16 (93.8%) reached formal restructuring (Ch11 or out-of-court)
• Median lag from appointment to Ch11: 2.5 months

Cumulus Media is the cleanest contemporaneous analog — Flaton appointed January 15, 2026 (one day before TSEOF), filed Ch11 March 5, 2026. 49-day lag.

LanzaTech's connection: Frizzley was appointed to LanzaTech's board March 20, 2025. She resigned January 31, 2026 — without a Ch11 filing, with the company stating departure was "not due to any disagreement." The KLDiscovery template (Frizzley appointed March 2024, resigned August 2024 at debt exchange close) suggests her resignation precedes either an imminent out-of-court restructuring or compressed Ch11 within 60-90 days.

What the market thinks

The +41.6%/month rally is driven by a January 21, 2026 reported Khosla "$81M acquisition" headline. Reverse-engineering market-implied probability from the price action: if the market priced E[r] near zero given a -55% event scenario and +5% no-event scenario, market-implied P(restructuring event) ≈ 8%. Our prior: 60%. Probability gap: ≈52pp.

Why the gap exists

1. Coverage: One analyst on a $300M name. Frizzley resignation is buried in an 8-K Item 5.02. Most retail/sell-side reads transcripts, not Item 5.02.
2. Misread insider signal: Khosla's Form 4 code remains unverified — Khosla is the SPAC sponsor, prior overwhelmingly favors transaction code A (grant), F (tax), or warrant conversion. Press misreads this as P (open purchase).
3. Pattern requires synthesis: The Flaton/Frizzley base rate isn't on the tape. The KLDiscovery template (n=1) for Frizzley-resignation-without-Ch11 is thinly cited.
4. Reflexivity is collapsing-into-reality, not bootstrap. The +41.6% move doesn't fix balance-sheet math.

Risks (ranked by impact)

1. Khosla Form 4 verifies as P (open purchase). Forces re-read of conviction; framework partially fails.
2. Execution surface degraded: no options chain, short interest 0.7%/0.8 days-to-cover (borrow tight or absent), illiquid. Equity expression difficult even when thesis is correct.
3. Out-of-court resolution with mild dilution — event resolves but equity recovers to $20-22 rather than collapsing.
4. n=1 KLDiscovery template for Frizzley-resignation-without-Ch11. Thin analog.
5. Squeeze continuation — illiquid name + retail momentum can extend 30-50% before reality adjudicates.

Catalysts

• April 30, 2026: TSEOF waiver cliff (sister-diagnostic validation)
• May 2026: LNZA Q1 2026 10-Q (going-concern language, advisor disclosure, debt classification)
• May-June 2026: Cumulus Media RSA execution updates (validates 49-day Flaton-lag analog)
• June 15, 2026: KLDiscovery template midpoint (≈5 months post-resignation)
• July 31, 2026: Prediction deadline

What would change our mind

• Khosla Form 4 verifies as transaction code P
• LNZA Q1 2026 10-Q without going-concern language and with no advisor disclosure
• Frizzley appointed to a healthy company in next 60 days (compromises base rate)
• TSEOF waiver materially extended (weakens sister-diagnostic validation)
• Apollo/Oaktree/Angelo Gordon/KKR absent from LanzaTech debt structure once disclosed
