Half of stated book is the whole argument — and the discount is half real, half fixable.

• The gap. Stated NAV of $3.66/share against a $1.78 price — a 52% discount, the widest in the sector. AerCap trades 1.31× book, Air Lease 0.85×, Willis Lease 1.39×.
• The permanent half. $111M market cap, B-rated debt at 6.6–6.8% versus 4.3–4.6% for investment-grade peers, $15.7M average daily volume. Sub-scale, junk-rated and concentrated is structural — the cost-of-funds gap was just locked in for five more years.
• The fixable half. The $298M unsecured note due October 2026 — the source of most of the discount — was redeemed ten months early in December 2025 and replaced with a $300M unsecured note due 2031. The binary maturity wall the discount priced is gone.

The $91.5M headline operating cash flow is roughly half non-recurring.

The bull anchors on operating cash flow approaching the entire market cap each year. The forensic read is harder: $32M is the recovery of a customer payment-plan receivable that was fully repaid by 30 June 2025, and $17.9M is lessee deposits the company is contractually obliged to refund or apply to future maintenance. HY26 already prints the bear math — operating cash flow before working capital ran $39.9M, annualizing below $80M. The September 2026 audited cash-flow walk decides which side is right.

Roughly 63% of stated equity is model-derived — tangible economic book is closer to $2.10.

• Revaluation reserve. $62M of the $244M reported equity is the fleet revalued through Other Comprehensive Income under the IFRS revaluation model — fair-value, not historical cost.
• Black-Scholes mark. Another $92M is a Level-3 fair-value carry on 24 ATR purchase rights. That single line swung +$46.9M in FY24 to –$21.6M in FY25 — a $68M two-year operating-profit swing driven by changes in option-pricing inputs.
• Reset the denominator. Strip both and tangible book lands at roughly $2.10/share. The headline 0.45× P/B is closer to 0.85× on a defensible book — most of the gap is accounting, not opportunity.

Liquidity, not valuation, is the binding constraint — the realistic exit is a takeout, not a re-rating cycle.

• No buyer can fit. Average daily volume of $15.7M against a $111M market cap. Five-day execution capacity at 20% participation is 0.17% of the company. The float supports roughly $320M of AUM at a 5% weight — most institutional mandates are physically locked out.
• The activist already harvested. Rangeley / Raper bought a 19% block from forced-seller Oceanwood at 79p in November 2023, accumulated to 25%, and has reduced to 5.96% into the company's own buyback. No replacement 5%+ holder has appeared on the register.
• The strategic path is real. Citi has been advising on strategic alternatives since FY23; founder Chatfield publicly stated openness to a sale at the right price in May 2023. AerCap, Air Lease, BOC Aviation and Avolon are the only buyers who can absorb the float at scale.

Five months of nothing, then one September print decides the trade.

• FY2026 audited results — late Sept / early Oct 2026. The only binary event in the window. Bull needs OCF before working capital at $85M+ with no fresh maintenance-reserve add-back and interest coverage walking through 1.5×. Bear needs another $20M+ reserve release and OCF below $80M.
• November 2026 AGM. Renews the 25%-of-capital buyback authority — the marginal bid in the tape on most days — and decides whether at-market equity-issuance authority is retained. A sub-NAV placing would empirically validate the structural-shenanigan path activist substacks have flagged.
• airBaltic IPO — CY2026 window. 17% of Avation's fleet sits with a lessee whose 2024 bonds priced at a 14.5% coupon. A completed IPO refinances the tail risk; another postponement re-introduces the FY21 setup on the second-largest concentration.
