The verdict

FTAI is a niche champion in fixing an ageing but still-growing fleet of jet engines, with two newer bets bolted on: asset-light aircraft funds and power turbines for data centres. The core business evidence is strong and confirmed by GE's own data. The risk sits in cash conversion, a broken margin promise, customer concentration and an unproven Power business, so the stock (~$175, more than 35% below its February…

Bull case — all positive points (most important first)

🐂 Bull #1The CFM56 aftermarket is tight for longer than expected

  • The point: Airbus and Boeing can't build new jets fast enough, so old CFM56-powered planes keep flying and need more heavy maintenance. FTAI's niche therefore stays busy through at least 2028.
  • Evidence:
    • GE cut its 2026 CFM56 retirement assumption from 3–4% to 1.5–2%.
    • GE expects ~2,400 CFM56 shop visits in each of 2026 and 2027 and teardowns up more than 10% in H1 2027.
    • ~30% of CFM56s have not had their first shop visit and two-thirds not their second [28,29,30].
    • Safran sees a plateau of 2,300–2,400 visits a year, with decline starting ~2029 [32].
    • Airbus targets only 70–75 A320s a month by end-2027 [35]. Oliver Wyman says supply-chain limits cap output "until at least 2030" [33].
  • Why it matters: Every year of delayed retirements is another year of high-margin module demand. It also slows the arrival of cheap used parts that would compete with FTAI's offer.
  • 😈 Devil's advocate:
    • GE's planning still allowed retirements to rise to ~3% in 2027 [31].
    • Once Boeing reaches 52/month and LEAP-1B durability kits cut over in early 2027, airlines may park CFM56s faster [30,36].
    • Low retirements also starve FTAI of feedstock engines. Its own Leasing guidance cut was blamed on diverting modules away from its fleet [6].
  • Verdict: Strong The main data comes from the OEMs themselves, who have no reason to talk up an independent rival. The horizon is 2026–2028, not forever.

🐂 Bull #2The OEMs are leaving the room; FTAI is the cheapest scaled independent

  • The point: GE and Safran prefer to put their shop capacity into LEAP. That leaves the CFM56 to independents, and FTAI is the only one built around module exchange at scale.
  • Evidence:
    • Adams: "the OEM portion of shop visits is about 20% now," and the OEMs "set up the platform for that to decline" [8].
    • FTAI's claimed market share went from low single digits in 2022 to ~14% [21].
    • Q2 2026: 296 modules (+61%). Capacity is going to 3,000/yr [6].
    • Capacity can grow without FTAI's own capex: GMF in Jakarta guarantees capacity for five years, EgyptAir runs a Cairo shop, and a Lisbon facility is planned [6,44].
    • Peers confirm tight capacity. StandardAero calls MRO capacity constrained, and MTU's MRO revenue rose 21% [39,40].
  • Why it matters: Share gains are self-reinforcing. More modules in the pool means faster swaps and more customers willing to sign fleet-wide deals.
  • 😈 Devil's advocate:
    • Share is being bought. Margin fell from ~35% to ~29% as FTAI took heavier, lower-margin work, and Bristlemoon argues scarcity may force further share gains at lower returns [6,21].
    • StandardAero has launched its own CFM56 programme [39].
    • FTAI's "market share" figures are its own and inconsistent: 12% vs 14% of a $25B market, and "more than 10%" of shop visits [7,8].
  • Verdict: Strong on position, Medium on profitability. The edge is cost and speed, and FTAI is already trading margin for volume.

🐂 Bull #3FTAI Power: a second life for run-out engines

  • The point: Data centres need power now, and big gas turbines are sold out to ~2030. A 25 MW turbine from a CFM56 core could ship within months, using engines FTAI already owns.
  • Evidence:
    • J&F signed a $1.465B initial purchase order under a five-year master supply agreement with "a leading international cloud service provider". Deliveries run through November 2027, with an advance payment at signing [9].
    • GE Vernova is "mostly sold out through '30" on gas turbines. It calls aeroderivatives a "bridge" because they commission in ~6 months versus ~18 for heavy-duty units [34].
    • Adams claims $7–8M EBITDA per unit and that "no one in the world can produce that turbine at a cost lower than we can" [8].
  • Why it matters: At management's 2027 guide of $450M, Power alone would be ~20% of 2027 segment EBITDA [3]. It also gives a value floor to engines that would otherwise be scrapped after 2029.
  • 😈 Devil's advocate:
    • No unit is in commercial service.
    • The customer is unnamed and not obliged to buy the maximum volume. Price falls if output underperforms (capped at 10%) [9].
    • ProEnergy already sells refurbished-core aeroderivatives to Crusoe, and Jereh sells its own gas-turbine gensets to US data centres. FTAI's packager is also a competitor [41,43].
    • The Q2 call conceded 2027 is "more prudent" for first delivery, and Power spending was raised by $150M plus $30M of R&D [6].
  • Verdict: Medium The order with cash up front is real evidence of demand. Execution, permitting and the partner structure are untested.

🐂 Bull #4Asset-light funds lock in captive demand and fees

  • The point: By selling its leased jets to SCI funds, FTAI frees capital, earns fees and turns each fund into an exclusive buyer of MRE modules.
  • Evidence:
    • SCI I is fully invested at ~$6B. MRE is the exclusive engine/module supplier for the Partnership's life [1,8].
    • H1 2026 MRE contract revenue was $404M [2].
    • SCI II targets $6B (15% FTAI co-investment). The stated goal is $20B of assets under management [6].
    • The first distribution was on 2026-06-30, and a first $612M ABS was issued [6].
  • Why it matters: It replaces a capital-hungry leasing book with fees plus a guaranteed module customer, which helps reduce leverage.
  • 😈 Devil's advocate:
    • This "customer" is a related party FTAI co-owns and services. FTAI eliminates part of the profit on sales to it ($16.6M in H1 2026), which shows the circularity [2].
    • If institutional appetite for aircraft funds cools, both the fees and the captive module demand shrink together.
    • The 2026 Leasing guide cut was partly blamed on slipped SPV closings [6].
  • Verdict: Medium The structure is clever and has worked once. But it raises the quality-of-revenue question (Bear #1, #3).

🐂 Bull #5The balance sheet is de-risking

  • The point: Credit quality is improving and near-term refinancing risk is low.
  • Evidence:
    • Moody's upgraded FTAI to Ba1 [6]. The revolver was upsized to $2.025B to April 2031 and is undrawn [12]. There are no bond maturities before the $1.0B 2028 notes [2].
    • $105M of 8.25% preferred was redeemed [6].
    • All Russia-stranded assets (8 aircraft, 17 engines) were settled via insurance, with $49.5M recovered in H1 2026 [2].
    • A $500M buyback was authorised to 2029 [18].
  • Why it matters: It lowers the chance that a cash squeeze forces dilution while Power and SCI II ramp.
  • 😈 Devil's advocate: Equity is only $404M against ~$3.2B net debt. Operating cash flow is negative. A buyback while inventory is growing could strain liquidity if Power slips [2].
  • Verdict: Medium

🐂 Bull #6Volume promises have been kept and beaten

  • The point: On the core business management has under-promised on volume and delivered.
  • Evidence: 2025 Aerospace EBITDA guidance was raised from $600–650M to $650–700M and delivered at $671M [4]. 2026 module targets were raised from 1,000 to 1,050 to 1,200 [6].
  • Why it matters: It makes the 1,700-module 2027 target more credible.
  • 😈 Devil's advocate: The margin, Leasing and FCF promises were missed in the same period (see Bear #2). Q1 and Q2 2026 EPS missed consensus [20].
  • Verdict: Medium The track record is strong on volume and weak on margin.

🐂 Bull #7Expectations have been reset

  • The point: The stock is more than 35% below its February 2026 high, so a lot of doubt about margins and Power is already in the price [21].
  • Evidence:
    • Kairos (a holder that is "not a buyer here") puts the stock at ~11x 2027 and ~9x 2028 adjusted EBITDA with no credit for Power [22].
    • Barclays kept Overweight and expects up to 60% earnings growth in 2027 [19].
  • Why it matters: The bar for positive surprises is lower.
  • 😈 Devil's advocate: 2027 guidance already includes $450M of Power EBITDA that hasn't been earned. If Power fails, the "cheap" multiple isn't cheap.
  • Verdict: Weak to Medium. This is a sentiment point, not a business strength.

Bear case — all negative points (most important first)

🐻 Bear #1Profits are not turning into cash, and the books are hard to read

  • The point: FTAI reports strong adjusted EBITDA, but GAAP operating cash flow is negative, and the definitions leave room for disagreement.
  • Evidence:
    • Net cash used in operations was −$265M in H1 2026 versus −$136M a year earlier. Inventory rose by $453M in the cash-flow statement [2].
    • Cash came instead from asset sales ($617M) [2].
    • Adjusted EBITDA adds FTAI's pro-rata share of unconsolidated entities' EBITDA [2,21].
    • Muddy Waters (January 2025) alleged that whole-engine sales were reported as "modules" (each engine counted as three), that gains on sale drove ~80% of segment EBITDA, and that depreciation moved between segments flattered margins [15].
    • The audit committee, with outside counsel and forensic accountants, found the claims "without merit" [16]. No regulator has tested them.
    • A securities class action (Shannahan v. FTAI, SDNY 25-cv-00541) was filed; its current status is not found [17]. The Q2 10-Q says management does not expect any proceedings to be material [2].
  • Why it matters: If the model really needs ever-larger inventory to grow, "adjusted FCF" overstates what owners can take out. Credibility shocks hit this stock hard: it fell 24% on the Muddy Waters day [16].
  • 🛡️ Counter-argument:
    • A growing exchange business must build its module pool first, and inventory is the product.
    • Management's adjusted FCF ($255M in H1, guide $878M) includes asset-sale proceeds that are part of the recycling model [6].
    • Leverage fell to 2.7x and Moody's upgraded, so creditors are comfortable [6].
  • Severity: High The counter-argument explains the gap but doesn't close it. Until GAAP operating cash flow turns positive, the accounting debate stays open.

🐻 Bear #2The 40% margin promise broke; growth is coming at lower returns

  • The point: Aerospace margins fell from ~35% in 2025 to ~29–30% in 2026. The 40%+ target was dropped.
  • Evidence:
    • Q2 2026 Aerospace margin was 29%. Management now says "about 30%" for the next 1–2 years [6].
    • The Q3–Q4 2025 calls had guided to 40%+, built on PMA blades, CFM parts and piece-part repair [23].
    • Bristlemoon: Aerospace gross margin went from 42.1% (FY22) to 30.5% (1H26) [21].
  • Why it matters: The three margin "pillars" (PMA, the CFM deal, in-house repair) haven't shown up yet. If heavier workscopes are the new normal, the profit per module is structurally lower.
  • 🛡️ Counter-argument: Heavier workscopes earn more dollars per engine (~$3M versus ~$2.5M in Adams' example). EBITDA still grew 51% year on year in Q2 [3,6]. PMA blades are said to be "performing as expected" [6].
  • Severity: Medium EBITDA dollars still grow, but a key credibility marker was missed.

🐻 Bear #3Heavy concentration, much of it with a related fund

  • The point: A handful of buyers, one of them a vehicle FTAI co-owns, take most of the output.
  • Evidence:
    • Three customers made up 57% of H1 2026 Aerospace revenue; two made up 50% of Q2 [2].
    • The 2025 Partnership bought $404M of MRE output in H1 [2]. FTAI owns 19% of it, services it, and books gains on aircraft sold to it ($17.6M in H1 2026) [2].
  • Why it matters:
    • Losing or pausing one airline programme, or an SPV slowing its purchases, would show up straight away in volumes.
    • Related-party revenue invites scepticism about arm's-length pricing.
  • 🛡️ Counter-argument: The Partnership is backed by outside institutional equity ($2.0B) and has a contractual, "customary market-based" price. FTAI also eliminates its share of profit [2].
  • Severity: Medium High.

🐻 Bear #4Power is unproven, competitive, and runs through a Chinese partner

  • The point: A large chunk of the growth story (and of 2027 guidance) rests on a product with no commercial track record.
  • Evidence:
    • First delivery is "end of 2026" with 2027 "more prudent" [6].
    • The $450M 2027 Power guide was set at the bottom of a $450–750M range [6].
    • The order is one unnamed customer, with no obligation to take the maximum volume and a price cut of up to 10% for underperformance [9].
    • The packaging JV partner Jereh is a Yantai (China) oilfield-equipment group that also sells its own gas-turbine gensets to US data centres [43].
    • No heat rate, emissions data or third-party test was found. Communities have pushed back on the noise of on-site turbines [42].
  • Why it matters: If Power slips a year, 2027 EBITDA drops toward ~$1.85B instead of $2.3B (interpretation: guidance minus the Power line). A Chinese partner in US data-centre power is a political target in the current trade climate.
  • 🛡️ Counter-argument: The advance payment shows a buyer committing cash. Prototypes have tested in Montréal and run in Miami [6,8]. GE Vernova's sell-out leaves real room for a bridge product [34].
  • Severity: Medium High.

🐻 Bear #5A finite asset: the CFM56 sunsets, and LEAP belongs to the OEMs

  • The point: FTAI's core is one engine family that starts declining around 2029.
  • Evidence:
    • Safran sees the CFM56 "sunset" from ~2029 [32].
    • LEAP turn-time and durability fixes are rolling out (the LEAP-1B kit gives ~2x time on wing, with full cutover from early 2027) [30].
    • GE's third-party LEAP channel is only mid-teens percent [30].
    • FTAI's LEAP entry is targeted for 2028–29 via the SPVs, with no product [6].
  • Why it matters: The current valuation needs the platform to outlive the CFM56 peak.
  • 🛡️ Counter-argument:
    • The fleet is young: two-thirds have had no second shop visit [30].
    • V2500 aftermarket support runs beyond 2045 per IAE [48].
    • Power gives run-out engines another use.
    • GE aims to grow third-party LEAP work toward ~30% by 2030 [30].
  • Severity: Medium The risk is slow and visible years ahead, not sudden.

🐻 Bear #6Feedstock squeeze: low retirements cut both ways

  • The point: FTAI needs cheap used engines. Fewer retirements mean less USM and costlier run-outs. Power will compete with the repair business for the same cores.
  • Evidence:
    • GE: there's "hardly any used material in the market" [30].
    • FTAI said module capacity is being diverted from its own leasing fleet to third parties, which contributed to the $100M Leasing guide cut [6].
    • Power needs ~100 cores for ~100 units [23].
    • GE expects power-generation conversions to absorb up to ~1 point of retirements [31].
  • Why it matters: Input costs could rise just as margins are already lower.
  • 🛡️ Counter-argument: FTAI owns ~1,000 CFM56 engines and buys from parked fleets. ~1,200 CFM56 aircraft are parked or stored [8,28].
  • Severity: Medium

🐻 Bear #7Thin equity, high leverage

  • The point: ~$3.2B net debt against only ~$404M of book equity, with negative operating cash flow.
  • Evidence: $3.5B of bonds; the first $1.0B is due in 2028; cash was $337M at 2026-06-30 [2].
  • Why it matters: It limits room for error if Power or SCI II slip, and a buyback adds to the cash call.
  • 🛡️ Counter-argument: 2.7x net leverage sits within the 2.5–3.0x target. The rating is improving and the revolver is large and undrawn [6,12].
  • Severity: Low Medium.

🐻 Bear #8Governance and insider signals

  • The point: Some signals deserve watching.
  • Evidence:
    • The CFO left in March 2026 [11].
    • Chairman Martin Tuchman sold 254,000 shares ($61.5M) at ~$241 in early May 2026. The Form 4s don't reference a 10b5-1 plan [14].
    • The only open-market purchase found was President Moreno buying ~$0.5M at $201 in July [14].
    • Fortress heritage: the new chief accounting officer worked on FTAI's reporting at Fortress [11].
  • Why it matters: Each is small on its own, but together they colour how the market reads Bear #1.
  • 🛡️ Counter-argument: The 8-K states the CFO's exit was unrelated to accounting [11]. The company has bought back the external management contract. The new CFO is an insider promotion.
  • Severity: Low

🐻 Bear #9Customers under fuel stress

  • The point: Airlines are FTAI's end customers, and 2026 is a weak profit year.
  • Evidence: IATA cut 2026 industry net margin to 2.0%, with jet fuel up ~69% after the Iran conflict [37].
  • Why it matters: Weak carriers defer maintenance or pay late.
  • 🛡️ Counter-argument: GE, MTU and StandardAero all report no deferrals or cancellations so far [30,39,40].
  • Severity: Low

Tailwinds NOT in the forecasts

  • Power ships near 100 units in 2027 — 30% chance within 36 months · Impact if it happens: High

    • What it is: 2027 Power EBITDA toward the $750M end of management's considered range instead of $450M [6].
    • Why it's not priced in: Guidance deliberately "assumes materially fewer" than 100 units. Kairos and others give Power no credit [6,22].
    • What would trigger it / the sign to watch: First commercial delivery by Q1 2027, then a monthly unit cadence disclosed on calls.
    • Why this probability: Doubling a first-year production plan with a new JV partner is rare, but the order book and cash deposit already exist.

  • A second named power customer — 40% chance within 36 months · Impact if it happens: Medium-High

    • What it is: A new order from a hyperscaler or utility, ideally a named one, beyond the five-year agreement with the first customer.
    • Why it's not priced in: Guidance and models are built on the single July order [3].
    • What would trigger it / the sign to watch: A J&F press release, or Jereh disclosures of US data-centre orders.
    • Why this probability: Demand for fast power is extreme, but buyers will likely wait for field hours on the first units.

  • CFM56 retirements stay ≤2% through 2028 — 40% chance within 36 months · Impact if it happens: Medium

    • What it is: A longer, flatter peak in shop visits.
    • Why it's not priced in: GE's own planning still assumes retirements rise toward ~3% in 2027 [31].
    • What would trigger it / the sign to watch: GE's Q3 call on 2026-10-20, Boeing and Airbus delivery shortfalls, and GTF groundings lasting past 2027.
    • Why this probability: Retirements have undershot every forecast for three years, but production is now recovering.

  • SCI reaches $20B of assets ahead of plan — 25% chance within 36 months · Impact if it happens: Medium

    • What it is: Larger fee income and more captive module demand.
    • Why it's not priced in: The 2027 guide carries only $450M for Leasing/SCI [3].
    • What would trigger it / the sign to watch: The SCI II final close size.
    • Why this probability: Fund I beat its target, but $20B is more than three times Fund I.

  • Earlier LEAP entry through an OEM licence or partnership — 15% chance within 36 months · Impact if it happens: High

    • What it is: A CFM agreement giving FTAI LEAP module or parts access before 2028.
    • Why it's not priced in: Management itself says 2028–29 [6].
    • What would trigger it / the sign to watch: An expansion of the January 2026 CFM materials agreement.
    • Why this probability: OEMs guard LEAP aftermarket margin closely.

Headwinds NOT in the forecasts

  • Power falls well short (<~$250M 2027 EBITDA) — 35% chance within 36 months · Impact if it happens: High

    • What it is: Delays from Mod-1 reliability, site permits, JV friction or a customer that buys fewer units.
    • Why it's not priced in: The $450M sits inside the official 2027 $2.3B guide [3].
    • What would trigger it / the sign to watch: No commercial delivery by mid-2027, or the Q3/Q4 2026 calls trimming the Power range.
    • Why this probability: First-of-a-kind hardware rarely ramps on schedule, and management already blinked once on timing.

  • Political or regulatory action against the Jereh JV — 15% chance within 36 months · Impact if it happens: Medium-High

    • What it is: US scrutiny of Chinese involvement in data-centre power, which could force a restructuring of J&F or a customer pull-back.
    • Why it's not priced in: It is not discussed in any filing or analyst note found.
    • What would trigger it / the sign to watch: Congressional letters, Commerce or CFIUS commentary on Chinese gensets for data centres.
    • Why this probability: The geopolitical climate is hostile, but J&F is a US LLC and FTAI's turbine core is US-sourced.

  • Retirements jump to 3–4% in 2027–28 — 25% chance within 36 months · Impact if it happens: Medium

    • What it is: More used material floods the market and pressures module pricing.
    • Why it's not priced in: Bulls and management assume continued scarcity [6].
    • What would trigger it / the sign to watch: GE's retirement data, and Boeing at 52/month plus Airbus at 75.
    • Why this probability: OEM ramps are real but have failed repeatedly.

  • Aerospace margin slides below ~27% — 30% chance within 36 months · Impact if it happens: Medium

    • What it is: The heavy-workscope mix, OEM parts costs and buying share push margins down further.
    • Why it's not priced in: Guidance and consensus anchor on "about 30%" [6].
    • What would trigger it / the sign to watch: Aerospace margin in Q3 2026.
    • Why this probability: The trend is down four quarters running, but management has a stated floor.

  • An accounting or legal re-run — 10% chance within 36 months · Impact if it happens: High

    • What it is: A new short report, SEC inquiry or an adverse class-action ruling, especially if operating cash flow stays negative.
    • Why it's not priced in: The audit committee clearance is treated as closure.
    • What would trigger it / the sign to watch: FY2026 operating cash flow, the 10-K legal section, and the SDNY docket.
    • Why this probability: No regulator activity was found in 20 months, but the cash gap keeps the target on.

Investment Risk Score: 55/100

Risk area Weight Score (0–100) Why
Business & competition 25% 50 Strong niche position, confirmed by OEM data. But it is one engine family with a ~2029 sunset, and the LEAP successor is OEM-controlled.
Financial health & dilution 20% 50 ~$3.2B net debt on $404M equity and negative GAAP operating cash flow, offset by a Ba1 upgrade, no maturities before 2028 and an undrawn $2B revolver.
Execution (delivering the plan) 20% 65 2027 guidance needs 1,700 modules, a first-of-a-kind Power ramp and SCI II, and margin promises were already missed.
Dependency & concentration 15% 65 3 customers make up 57% of Aerospace revenue, a related fund is a top buyer, Power has one customer, and CFM is both supplier and rival.
Regulation, policy & geopolitics 10% 50 Chinese JV partner, the open Section 232 aircraft-parts tariff window (~January 2027) [38], a big Canadian site, and turbine emissions permitting. Russia exposure is now resolved.
Sentiment & expectations 10% 45 The stock is more than 35% off its high and multiples are compressed, but guidance already includes unproven Power EBITDA.

Overall = 55/100 (high). The core engine business is lower-risk than the score suggests. What lifts the score into "high" is three things together: negative operating cash flow, a short-seller history, and 2027 guidance that depends on a first-year Power ramp with a Chinese packaging partner. This is the first deep dive, so there is no change to report.

Conclusion

  • What kind of company this is: A specialist industrial-services company riding the peak of one engine generation, with an asset-management arm and a start-up power business attached. Owning it is a bet on three things:
    • the CFM56 module business stays scarce and growing through 2028;
    • SCI keeps recycling capital into fees and captive demand;
    • Power becomes a real second engine before the CFM56 fades.
  • The 2–3 things that will decide the outcome:
    1. Power delivering units on time at the claimed $7–8M EBITDA each.
    2. Operating cash flow turning positive as inventory build slows.
    3. The CFM56 retirement rate in 2027–28.
  • Signposts:
    • Confirm bull:
      • First commercial Mod-1 deliveries by Q1 2027.
      • A second power order, ideally from a named customer.
      • Positive GAAP operating cash flow for a full half-year.
      • GE keeps 2027 retirements ≤2%.
      • Aerospace margin stabilises at ≥30%.
    • Break bull:
      • Power first delivery slips past mid-2027, or the Power range is cut.
      • A new short report or SEC inquiry.
      • Aerospace margin below ~27%.
      • SCI II closes well below $6B.
      • Retirements spike to 3%+.
  • Balanced verdict:
    • The best bull case: FTAI has built the lowest-cost, fastest way to maintain the world's largest jet-engine fleet, just as the OEMs step away and new jets stay scarce, and it now has a credible route to reuse those same engines in the AI power boom.
    • The best bear case: the profits are adjusted, the cash is negative, the biggest customer is FTAI's own fund, the margin target already broke, and 20% of next year's EBITDA guidance depends on a product that hasn't shipped, built with a Chinese partner.
    • Today the evidence leans toward the core business being genuine and durable to ~2028; independent OEM data backs the demand side. The Power and cash-conversion questions are open and decide whether that turns into value.

Open questions & data gaps

  • Who the top customers are. The three unnamed customers are not identified. Our inference that the 2025 Partnership is one of them is not confirmed. This matters: it drives how much revenue is truly third-party.
  • J&F JV terms. FTAI's stake ("25–50%"), capital commitments, the dollar value of Jereh's share and who carries the warranty: not found. Nothing on this is in the Q2 10-Q. This matters a lot for Power's real economics.
  • Mod-1 performance. Heat rate, emissions certification and unit price: not found.
  • Class action status (SDNY 25-cv-00541): not found.
  • Primary transcripts. Full primary call transcripts were not retrieved: the Q2 call came via Investing.com, and the Q3/Q4 2025 and Q1 2026 calls via summaries only. Quotes from those calls carry that caveat.
  • Price data. Share price levels come from aggregators. "More than 35% below the February high" is Bristlemoon's figure. The ~$175 close on 2026-10-07 is from ChartRow.
  • Q3 2026 report date: not confirmed. Historically it falls in late October.
