Refrigerant reclamation and cooling conversion

The AIM Act's binding HFC phase-down (85% below baseline by 2036) plus the EPA Emissions Reduction and Reclamation (ER&R) rule convert environmental regulation into recurring, largely non-discretionary demand for recovery, reclamation, leak detection and low-GWP replacement equipment across a large installed cooling base. Because virgin HFC supply is contractually capped and steps down sharply (consumption allowances fall from 181.5M MTEVe in 2026-2028 to 90.8M in 2029-2033), reclaimed refrigerant and the low-GWP chemistry replacing legacy gas gain structural scarcity value. Early transmission is visible: reclaimed HFC volumes rose ~30% in 2024, Hudson realized HFC pricing near $6/lb in Q1 2026, and Chemours' low-GWP Opteon franchise grew double digits. Investability is uneven — pure-play reclaimers and refrigerant-chemical franchises show the cleanest exposure, while diversified HVAC OEMs capture the conversion cycle but dilute the reclamation-specific economics.

Why this theme may be investable

Refrigerant regulation creates recurring demand for recovery, reclamation, leak detection, servicing and replacement equipment across the installed cooling base. As the phase-down of high-GWP refrigerants tightens virgin supply, the value of certified reclamation capacity, technician labor, low-GWP feedstock (R-32, HFOs) and A2L-ready equipment rises — shifting economics from one-time equipment sales toward a compliance-driven, annuity-like servicing and reclaimed-supply economy.

Why now

The regulatory step-change is live in 2026: the ER&R rule's leak detection/repair requirements took effect Jan 1, 2026 for systems with 15+ lb of HFCs (src-hunton-status); the 2026-2028 allowance window sits at 181.5M MTEVe before a sharp step to 90.8M in 2029 (src-hunton-status); and the Jan 1, 2029 mandate to service supermarket, refrigerated-transport and ice-maker subsectors with reclaimed HFCs is now inside investors' horizon (src-hunton-status, src-epa-final-rule). Demand signals corroborate the timing — EPA reported reclaimed HFC volumes up ~30% in 2024 vs 2023 (src-epa-reclaim-trends), Hudson realized HFC pricing near $6/lb in Q1 2026 (src-hudson-stocktitan), and Chemours' TSS/Opteon low-GWP sales grew double digits into the 2026 cooling season (src-chemours-forecast). An offsetting development is EPA's Oct 3, 2025 Technology Transitions reconsideration, which would relax some GWP thresholds (src-hunton-status).

Source of pricing power

Pricing power derives from a regulatory cap on virgin HFC supply (declining allowance pool), certification and purity barriers that limit who can reclaim and resell refrigerant, scarce technician/servicing capacity, and a 2029 statutory mandate to use reclaimed HFCs in defined subsectors — all of which make reclaimed supply and low-GWP chemistry harder to substitute and support a widening virgin-to-reclaimed price spread.

Duration and maturity

Multi-year to structural: the phase-down schedule runs through 2036 with a hard 2029 allowance step-down, giving a 3-10 year horizon. The conversion cycle (high-GWP to A2L equipment) is early-to-mid stage; the reclamation supply economy is early stage (volumes still small relative to installed-base demand and scaling ~20-40%/yr), with the 2029 servicing mandate as the key maturation trigger.

Causal chain

How the change becomes cash flow

  1. The AIM Act caps and steps down virgin HFC production/consumption allowances (181.5M MTEVe in 2026-2028, 90.8M in 2029-2033), structurally constraining virgin supply and raising virgin refrigerant prices.
  2. EPA Technology Transitions GWP limits push new AC/refrigeration equipment onto lower-GWP refrigerants (e.g., R-454B, R-32), driving a multi-year equipment conversion cycle.
  3. The large legacy installed base still running high-GWP gas requires continued servicing, and the ER&R leak-detection/repair rule (effective Jan 1, 2026) raises the frequency and cost of leak management.
  4. Recovered refrigerant must be reclaimed to purity standards, certified and redistributed; from Jan 1, 2029 certain subsectors must be serviced with reclaimed HFCs.
  5. Reclaimed supply becomes an economically important substitute that backfills the widening gap between capped virgin supply and installed-base demand, supporting reclaimed pricing.
  6. Reclaimers, low-GWP refrigerant producers, and equipment/service providers with certified capacity and technician reach capture recurring compliance-driven demand.
Market evidence

Dated, sourced indicators

Regulatory facts are drawn from EPA primary materials (Sept 23, 2024 final ER&R rule press release; EPA reclamation-trends and HFC-reclamation background pages) and corroborated by a specialist legal status update (Hunton, current to 2026) that supplied the precise allowance step-downs and effective dates. Company demand/pricing evidence is current (Q1 2026 earnings). Reclamation-volume growth is EPA-reported through 2024 only — the exact pound totals sit in EPA's downloadable spreadsheets that could not be parsed in this pass, so only YoY growth ranges are cited. Refrigerant retail/wholesale pricing is trade-press pricing surfaced via web search (not a directly parsed primary page) and should be treated as directional. Scope skews U.S.; global figures are limited to Chemours segment disclosure.

Market context: No clean public dollar market size for U.S. reclaimed refrigerant was obtainable in this pass; the addressable pool is best proxied by the regulated virgin-supply ceiling that reclaimed supply must increasingly backfill — U.S. HFC consumption allowances of 181.5M MTEVe in 2026-2028 stepping down to 90.8M in 2029-2033 and 60.5M in 2034-2035. Roughly 75% of HFC use is in refrigeration and air conditioning, indicating the installed base that generates recoverable/serviceable volume. ( as of 2026)[5]

Investment transmission

Who captures the economics

Business models

  • Refrigerant reclamation, certification and redistribution (recover recovered gas, reprocess to AHRI-700 purity, resell certified reclaimed refrigerant)
  • Low-GWP refrigerant chemical manufacturing (HFO and HFO/HFC blends such as Opteon, R-454B components)
  • HVAC/refrigeration equipment OEMs converting product lines to A2L / lower-GWP platforms
  • Field service, leak detection/repair and refrigerant management/tracking
  • Compressors, controls and components engineered for A2L refrigerants
  • Refrigerant distribution and cylinder/lifecycle management

Bottlenecks and scarce assets

  • Certified reclamation capacity and separation technology for complex next-generation blends
  • Technician / field-service labor capacity to perform recovery and leak management
  • Low-GWP feedstock and chemistry (R-32, HFOs) and associated IP/licensing
  • Reclaimed-supply availability relative to installed-base servicing demand ahead of the 2029 mandate
  • Tracking, certification and EPA enforcement capacity that determines whether compliance demand is real

Financial transmission

Reclamation economics hinge on the spread between virgin and reclaimed refrigerant prices and on reclaimed throughput: Hudson's Q1 2026 gross margin was ~20% (down from 22% on a less favorable mix with fewer high-margin HFO products), illustrating that a rising-price thesis can be offset by mix and inventory timing (src-hudson-stocktitan). Refrigerant-chemical franchises show the strongest through-cycle margin capture — Chemours' TSS segment posted 33% adjusted-EBITDA margin in Q1 2026 on 22% sales growth (src-chemours-forecast). For HVAC OEMs the transmission is volume/backlog and pricing on a conversion cycle rather than reclamation-specific margin, and is more cyclical and capex-sensitive. Cash-flow quality is best where recurring compliance demand meets scarce certified capacity (reclaimers, low-GWP producers) and weakest where exposure is diffuse across large diversified portfolios.

Value chain

Where value is retained

  • Low-GWP virgin refrigerant production (HFO / blends)retains value

    Manufacturers of next-generation refrigerants and feedstock (e.g., HFOs, R-32) benefiting from mandated migration and constrained legacy supply; IP- and capacity-protected.

  • Refrigerant reclamation and certificationretains value

    Certified reclaimers that reprocess recovered gas to purity standards and resell it; scarce certified capacity plus the 2029 reclaimed-servicing mandate support pricing.

  • Recovery, servicing, leak detection and repairuncertain

    Technicians, tools and management platforms performing recovery and the Jan 2026 leak-management workflow; demand is recurring and compliance-driven but the labor pool is fragmented and capacity-constrained.

  • HVAC / refrigeration equipment OEMs (A2L conversion)volume only

    Equipment makers converting to R-454B/R-32 platforms; captures the conversion cycle but is cyclical, competitive and largely passes refrigerant cost through.

  • Compressors, controls and A2L componentsuncertain

    Suppliers of A2L-ready compressors, sensors and controls enabling the conversion; enabling exposure whose theme-specific margin capture is unproven from public data.

  • Distribution, tracking and enforcement technologyuncertain

    Refrigerant distribution, cylinder management and compliance/tracking tools underpinning enforcement; second-order exposure dependent on enforcement intensity.

Scenarios

Base, upside, and downside

base

The AIM Act phase-down and ER&R rule remain in force broadly as written. Virgin HFC supply keeps tightening into the 2029 allowance step-down, virgin prices stay elevated, reclaimed volumes keep compounding at roughly 20-40%/yr off a small base, and the conversion to A2L equipment proceeds. Reclaimers and low-GWP refrigerant producers grow revenue with periodic margin volatility from mix and pricing; HVAC OEMs ride a steady conversion cycle.

Measurable triggers

  • Allowance pool steps to 90.8M MTEVe in 2029 on schedule
  • Reclaimed-HFC volumes continue double-digit annual growth
  • Virgin/reclaimed HFC prices persist above legacy levels through the cooling season

Likely beneficiaries: Hudson Technologies (reclamation pure-play); Chemours (low-GWP Opteon franchise); HVAC OEMs converting to A2L (Carrier and peers)

Likely losers: Buyers reliant on cheap virgin HFCs; Operators of leak-prone legacy systems facing rising compliance cost

upside

Enforcement tightens and the 2029 reclaimed-servicing mandate plus stricter leak rules bind harder than expected, while state-level accelerations (e.g., California, New York) pull demand forward. Virgin supply gaps widen faster than reclaimed capacity can scale, driving a stronger virgin-to-reclaimed spread and premium pricing for certified reclaimers and low-GWP producers with separation capability for complex blends.

Measurable triggers

  • Aggressive EPA/state enforcement against illegal imports and non-compliant sales
  • Reclaimed supply falls short of 2029 servicing demand, lifting reclaimed prices
  • State phase-downs accelerate ahead of the federal schedule

Likely beneficiaries: Certified reclaimers with blend-separation capacity; Low-GWP refrigerant and licensing holders; Service networks with technician capacity

Likely losers: Non-compliant importers/distributors; Late-converting equipment owners

downside

Deregulatory reconsideration and litigation erode the rules: the Oct 3, 2025 Technology Transitions reconsideration relaxes GWP thresholds, the D.C. Circuit challenge weakens enforcement, and reclaimed supply scales faster than mandated demand — producing structural oversupply. Virgin prices soften as allowances are managed loosely, compressing the virgin-to-reclaimed spread and undermining the reclamation annuity thesis.

Measurable triggers

  • Material rollback of Technology Transitions / ER&R provisions
  • Weak or deprioritized EPA enforcement
  • Reclaimed inventories build faster than 2029 demand, pressuring reclaimed prices

Likely beneficiaries: Low-cost equipment buyers and legacy-system operators

Likely losers: Reclamation pure-plays dependent on the virgin/reclaimed spread; High-cost low-GWP producers if migration slows

Valuation and cycle context: Theme-level, public-eligible observations only — no security-specific multiples or targets. The clearest near-term financial evidence is mixed: Chemours' Thermal & Specialized Solutions segment delivered a record Q1 2026 with 33% adjusted-EBITDA margin and 22% sales growth (src-chemours-forecast), yet the parent posted a group net loss, showing that segment strength can be masked at the consolidated level. Hudson, the purest reclamation proxy, grew Q1 2026 revenue 9% but saw gross margin slip to ~20% from 22% on mix, and guided Q2 2026 revenue to $73-76M while cautioning that Q2 HFC prices could run below the prior year as the R-454B shortage normalizes (src-hudson-stocktitan). The read-through: the regulatory demand backdrop is strengthening, but realized pricing and margins are volatile quarter-to-quarter, so the theme should be underwritten on multi-year volume/spread expansion rather than smooth near-term earnings. Cross-company valuation comparison was not possible in this pass because segment-level reclamation revenue is not separately disclosed by most mapped OEMs and SEC filing pages could not be retrieved.

Catalysts

Dated catalysts

  • 2026 cooling season (Q2-Q3 2026)

    Peak seasonal refrigerant demand; Chemours guided Q2 2026 consolidated sales up 15-20% sequentially and Hudson guided Q2 revenue to $73-76M — a real-time test of demand and pricing.[8]

  • Effective Jan 1, 2026 (ongoing)

    ER&R leak detection/repair requirements are live for systems with 15+ lb of HFCs, raising recurring servicing and reclamation demand across the installed base.[5]

  • 2026 (pending decision)

    D.C. Circuit litigation challenging the Technology Transitions Rule, plus EPA's Oct 3, 2025 reconsideration proposal — outcomes will confirm or weaken the conversion-side rules.[5]

  • Jan 1, 2029

    Allowance pool steps down to 90.8M MTEVe and mandated reclaimed-HFC servicing begins for supermarket, refrigerated-transport and ice-maker subsectors — the key structural inflection for reclaimed demand.[5]

  • Annual (EPA data releases)

    EPA reclamation-trends updates (reported volumes, most recently ~30% growth in 2024) provide a recurring gauge of whether reclaimed supply is scaling toward the 2029 requirement.[2]

Risks and disconfirming evidence

What breaks this thesis

Material risks

  • Regulatory rollback/relaxation: EPA's Oct 3, 2025 Technology Transitions reconsideration would raise several GWP thresholds and shift chiller deadlines, potentially slowing the conversion cycle (src-hunton-status).
  • Litigation risk: an industry challenge to the Technology Transitions Rule is pending in the D.C. Circuit and could alter or delay requirements (src-hunton-status).
  • Weak enforcement: the thesis depends on EPA/state enforcement against illegal imports and non-compliant sales; lax enforcement undercuts compliance demand.
  • Reclaimed oversupply: if reclaimed capacity scales faster than mandated demand, the virgin-to-reclaimed spread compresses (an explicit thesis break).
  • Pricing normalization: Hudson flagged that Q2 2026 HFC prices could fall below the prior year as the R-454B shortage normalizes, showing near-term price fragility (src-hudson-stocktitan).
  • Margin/mix volatility: reclamation gross margins swing on product mix and inventory timing (Hudson margin fell to ~20% from 22% in Q1 2026) (src-hudson-stocktitan).
  • HVAC cyclicality: OEM conversion exposure is tied to construction/replacement cycles and macro demand, diluting the compliance-annuity character.
  • Diversification dilution: for large multi-segment companies, reclamation/refrigerant exposure may be immaterial to consolidated results.
  • Technician capacity: a shortage of certified technicians could throttle the servicing/recovery that feeds reclaimed supply, cutting both ways for the thesis.

Thesis-break conditions

  • Regulations reversed or materially relaxed: repeal/weakening of the AIM Act phase-down, ER&R servicing/leak rules, or Technology Transitions GWP limits (e.g., the 2029 reclaimed-servicing mandate is rescinded or the allowance step-down to 90.8M MTEVe is deferred).
  • Enforcement remains weak: sustained absence of EPA/state enforcement such that non-compliant virgin/illegal supply persists and compliance-driven reclamation demand fails to materialize.
  • Reclaimed supply structurally oversupplied: reclaimed inventories and capacity grow faster than mandated/served demand, collapsing the virgin-to-reclaimed price spread and eliminating reclaimer pricing power (measurable via falling reclaimed prices despite rising virgin prices).

Unresolved questions

  • What is the credible dollar size and growth rate of the U.S. reclaimed-refrigerant market? EPA reports volume growth but a clean market-size figure was not obtainable in this pass.
  • Will reclaimed supply be sufficient to meet the Jan 1, 2029 reclaimed-servicing mandate, or will a shortfall lift reclaimed pricing (upside) versus an oversupply (downside)?
  • What is the current corporate status of Honeywell's low-GWP refrigerant business? The Hudson licensing counterparty was named 'Solstice', consistent with a separation of Honeywell's Solstice/Advanced Materials refrigerant operations — this could not be verified in this pass and materially affects Honeywell's exposure.
  • How material is refrigerant/reclamation exposure to consolidated results at Trane, Johnson Controls, Daikin, Lennox, Emerson, Modine and SPX? Segment-level disclosure was not retrievable here.
  • How binding is technician/service-labor capacity as a bottleneck, and are there quantitative data on certified-technician supply versus demand?
Researched company map

12 assessed companies

Every mapped company is assessed with evidence-qualified exposure. Materiality is claimed only where disclosure supports it.

Refrigerant reclamation, distribution and refrigerant-management pure-play (recovers, reclaims to purity standards, and resells certified refrigerant).

Hudson Technologies HDSN

Highest and most direct exposure among mapped names. Reclamation and refrigerant sales are the core business; management ties growth explicitly to the AIM Act phase-down and expects reclaimed refrigerant to 'fill the void' between reduced virgin supply and market demand. Q1 2026 revenue was $60.2M (+9% YoY) with ~20% gross margin, realized HFC pricing near $6/lb, Q2 2026 guidance of $73-76M, and new licensing for R-448A/R-449A reclaim-and-resale.

Evidence
Hudson's Q1 2026 issuer release and filed Form 8-K directly establish current results, reclamation capability, separation plants and EMERALD reclaimed products. Reclaimed-versus-virgin economics are not separated.
Materiality
disclosed — Refrigerant sales and reclamation are the issuer's core operations. Q1 2026 company revenue was $60.2 million, but reclaimed mix and margin remain undisclosed.
Investability view
Cleanest listed proxy for the reclamation bottleneck; the analytical crux is scaling reclaimed throughput and the virgin-to-reclaimed price spread against quarter-to-quarter mix and pricing volatility (Q1 2026 margin compression and cautious Q2 price commentary illustrate the swing risk).

Next diligence: Quantify full-year reclaimed volume (pounds) and reclaimed-vs-virgin realized pricing; assess separation capacity for next-gen blends and the economics of the R-448A/R-449A licensing.

HVAC equipment OEM and service provider on the cooling-conversion side (residential/light-commercial and commercial systems migrating to lower-GWP refrigerants).

Carrier Global CARR

High conversion-side exposure. Carrier publicly markets R-454B under 'Puron Advance' (GWP 466 vs R-410A's 2,088, ~78% lower) as the industry-standard replacement, and states most new residential HVAC it produces today is designed for R-454B — placing its core product line squarely in the conversion cycle. Its exposure is to equipment conversion and service, not to refrigerant reclamation per se.

Evidence
Carrier's official R-454B release directly establishes low-GWP conversion capability. Q2 2026 issuer results establish company and Climate Solutions Americas economics, but not reclamation economics.
Materiality
not assessed — Carrier discloses broad Climate Solutions economics and R-454B capability but no reclamation-specific revenue, profit, volume or installed capacity.
Investability view
A broad way to play the conversion cycle rather than the reclamation bottleneck; upside is tied to replacement/new-build demand and A2L mix, with limited direct capture of reclaimed-supply economics.

Next diligence: Retrieve Carrier's latest 10-Q/earnings to size HVAC segment growth, A2L backlog and pricing; assess whether any aftermarket/service revenue is reclamation-linked.

Commercial and residential HVAC OEM with a large service/aftermarket franchise; conversion-side exposure to lower-GWP equipment and refrigerant management.

Trane Technologies TT

Direct conversion and reclaim capability is evidenced: Trane is shifting residential products to R-454B, and its 2025 sustainability report says more than 160 stores and distribution partners collected recovered refrigerants representing more than 794,000 metric tons CO2e. Financial materiality is not disclosed.

Evidence
Trane's Q1 2026 issuer results, 2025 sustainability report and R-454B portfolio release directly support operating scale, reclaim-program activity and conversion capability.
Materiality
not assessed — The issuer quantifies reclaim activity environmentally, not as revenue, profit, refrigerant pounds or facility utilization; theme-specific financial materiality remains unassessed.
Investability view
Likely a diversified conversion/service beneficiary rather than a reclamation-specific play; requires evidence before any exposure conclusion.

Next diligence: Fetch Trane's latest 10-Q/annual report and EcoWise/low-GWP disclosures; size service-and-aftermarket revenue and any refrigerant-transition commentary.

Building controls and HVAC OEM; diversified exposure to cooling equipment, service and building systems.

Johnson Controls JCI

Direct low-GWP conversion capability is evidenced across residential, light-commercial and commercial ducted HVAC. Fiscal Q2 2026 results establish broad scale, but no reclamation business or theme-specific economics.

Evidence
Johnson Controls' fiscal Q2 2026 issuer release and official refrigerant-transition page directly support current operating scale and R-454B portfolio conversion. They do not support reclamation capture.
Materiality
not assessed — Official sources do not isolate refrigerant-conversion or reclamation revenue, profit, orders, backlog or volume.
Investability view
Refrigerant/reclamation is likely a small slice of a broad buildings portfolio; treat as diffuse exposure pending evidence.

Next diligence: Review JCI segment disclosures for HVAC/refrigerant revenue and any low-GWP transition or service commentary.

Global HVAC OEM and refrigerant producer with disclosed recovery and reclamation infrastructure.

Daikin Industries 6367.T

Direct capability is supported. Daikin reports R-32 equipment growth, a licensed Japanese reclamation facility, a 60-service-station recovery system, a Frankfurt reclamation plant and U.S. recovery bases. The issuer does not isolate reclamation economics.

Evidence
Daikin's fiscal 2025 financial data and results presentation establish current group scale and R-32 adoption. Its 2025 sustainability report documents 31 tons reclaimed at Yodogawa in fiscal 2024 and multi-region recovery and reclamation activity.
Materiality
not assessed — Official sources establish operating capability and throughput, but do not disclose reclamation-specific revenue, profit, pricing, capacity utilization or capital returns.
Investability view
Daikin has verified conversion and reclamation capability, but the theme-specific economics and licensed current valuation are unresolved; keep NOT_READY.

Next diligence: Obtain reclamation revenue, profit, pricing, capacity and utilization; separate R-32 conversion economics from broader HVAC results.

Residential and commercial HVAC equipment OEM with direct lower-GWP conversion exposure.

Lennox International LII

Official product evidence establishes Lennox's use of R-454B for whole-home systems and R-32 for ductless equipment. Q1 2026 results establish operating scale, but no reviewed source establishes reclamation activity or theme-specific economics.

Evidence
Lennox's Q1 2026 issuer release, Form 10-Q and official R-454B guide directly support current results and product conversion. They do not support a reclamation business.
Materiality
not assessed — Official sources do not isolate refrigerant-conversion or reclamation revenue, profit, orders, backlog, volume or capacity.
Investability view
A verified equipment-conversion beneficiary rather than a reclamation play; theme-specific economics and licensed current valuation remain unresolved.

Next diligence: Obtain conversion-specific revenue, margin, backlog or mix and determine whether Lennox offers refrigerant recovery, management or reclamation services.

Refrigerant chemical manufacturer; producer of low-GWP Opteon (HFO) refrigerants and legacy Freon, plus components used in blends.

Chemours CC

High and disclosed exposure via the Thermal & Specialized Solutions (TSS) segment. Q1 2026 TSS net sales were $568M (+22% YoY, record Q1) at 33% adjusted-EBITDA margin; Opteon low-GWP sales were $313M (+12%) with Freon up 67% to $162M on transition demand — directly capturing both the phase-down and conversion. Higher R-32 input costs are a partial offset.

Evidence
Chemours' official Q1 2026 release and presentation directly report TSS, Opteon, Freon and segment-margin figures. Its official 2023 statement supports reclamation and recycling licensing activity, which remains financially unsegmented.
Materiality
disclosed — Refrigerants are a separately disclosed, material reportable segment (TSS) with quantified sales, growth and margin, though it sits within a broader chemicals company that posted a group net loss.
Investability view
Strong low-GWP chemistry proxy with the clearest margin capture in the value chain; the analytical crux is Opteon volume/pricing durability versus R-32 input-cost pressure and parent-level (non-refrigerant) drag.

Next diligence: Track Opteon volume vs price mix, R-32 sourcing costs, TSS margin sustainability, and parent leverage/free-cash-flow that could overshadow segment strength.

Historical lower-GWP refrigerant producer; the Solstice and Advanced Materials business was spun off and is no longer part of Honeywell's current reporting perimeter.

Honeywell HON

Current direct exposure fails the reviewed capability gate. Honeywell completed the spin-off of Advanced Materials as independent Solstice Advanced Materials on October 30, 2025, and reports that business as discontinued operations. The refrigerant franchise now trades separately as SOLS and is outside this canonical Honeywell relationship.

Evidence
Honeywell's official spin-completion release and supplemental financial information directly establish the separation, independent Nasdaq listing and discontinued-operations treatment. No reviewed source establishes a residual Honeywell-parent refrigerant or reclamation business after the spin.
Materiality
not assessed — The mapped exposure is stale at the current Honeywell parent perimeter. Solstice Advanced Materials, not Honeywell, owns the separated refrigerant business; no current Honeywell-parent theme economics are established.
Investability view
Treat the current Honeywell parent as having no verified direct refrigerant exposure. Do not substitute Solstice without a later canonical-universe decision.

Next diligence: Decide in a later canonical-universe update whether the stale Honeywell relationship should be removed or remapped; do not add Solstice automatically.

Compressors and controls supplier (former Emerson Climate Technologies) enabling A2L-ready refrigeration/HVAC systems and cold-chain.

Copeland

Current official sources verify a broad A2L-qualified compressor, condensing-unit, controls and leak-detection portfolio for refrigeration and air conditioning. They do not establish reclamation activity or theme-specific economics. Copeland is a private Blackstone portfolio company; Emerson no longer retains an interest.

Evidence
Copeland's official A2L product page and 2025 Global Impact Report directly support lower-GWP conversion capability. Emerson's FY2025 Form 10-K directly supports the completed sale of its remaining Copeland interest.
Materiality
not assessed — Capability is direct, but no reviewed public source quantifies A2L or reclamation revenue, profit, volume, capacity or utilization; no public-equity valuation is possible.
Investability view
Not directly investable as public equity. Treat as a private conversion-capability benchmark, not as a listed-company candidate or reclamation pure play.

Next diligence: Obtain audited financial disclosure, A2L product economics, reclamation activity and any investable public debt details before human review.

Historical owner of the former Climate Technologies business; no verified current refrigerant or Copeland ownership exposure.

Emerson Electric EMR

Current capability fails. Emerson completed the sale of its 40% non-controlling Copeland interest and seller note in August 2024. Its current reporting perimeter is automation-focused and does not establish a refrigerant-reclamation business.

Evidence
Emerson's FY2025 Form 10-K directly confirms the completed sale and discontinued-operations treatment.
Materiality
not assessed — The reviewed filing establishes that the mapped ownership exposure ended; no current Emerson-parent theme economics exist in the reviewed reporting perimeter.
Investability view
Treat the current relationship as stale. Do not infer refrigerant exposure from historical ownership or automatically substitute another issuer.

Next diligence: Resolve the stale Refrigerant Reclamation relationship in a later canonical-universe update; do not remap automatically.

Thermal-management supplier (heat exchangers, coils, cooling systems) serving HVAC/refrigeration and adjacent markets.

Modine Manufacturing MOD

Direct conversion capability is verified: Modine sells commercial refrigeration products and develops solutions for next-generation and lower-emission refrigerants. FY2026 Climate Solutions was 65% of sales, but data centers and acquired HVAC products drove most growth; reclamation activity is not established.

Evidence
Modine's FY2026 Form 10-K directly supports HVAC&R products, commercial refrigeration, low-GWP development, Climate Solutions mix and current segment growth drivers.
Materiality
not assessed — Climate Solutions is financially material, but the filing does not isolate reclamation or refrigerant-transition revenue, profit, orders or volume from data-center and broader HVAC activity.
Investability view
Verified as a broad cooling-conversion supplier, but current growth is data-center-led and the reclamation thesis is not financially isolated.

Next diligence: Obtain reclamation activity and refrigerant-transition-specific economics; separate commercial refrigeration from data-center cooling growth.

HVAC cooling and commercial/industrial refrigeration-equipment supplier; no verified refrigerant-reclamation or refrigerant-leak-detection role.

SPX Technologies SPXC

Current official sources verify package and process cooling and commercial/industrial refrigeration products. FY2025 HVAC revenue was $1.52 billion and Q1 2026 HVAC revenue was $394 million, but no reviewed evidence establishes reclamation or low-GWP conversion economics. Detection & Measurement leak detection concerns utility infrastructure, not refrigerants.

Evidence
SPX's FY2025 Form 10-K, Q1 2026 Form 10-Q and official HVAC portfolio page directly support the bounded cooling and refrigeration-equipment role and segment economics.
Materiality
not assessed — HVAC is financially material, but reclamation and refrigerant-transition revenue, profit, orders and volume are not separately disclosed; utility leak detection is outside this claim.
Investability view
Verified as a diversified HVAC cooling supplier, not as a refrigerant-leak-detection or reclamation pure play.

Next diligence: Obtain official low-GWP conversion or reclamation product evidence and theme-specific economics before human review.
