Thematic Exposure -- 8/10

ResMed is the clear #1 in the global sleep apnea / respiratory care market — a structurally undersupplied, demographically driven medical-device duopoly augmented by an out-of-hospital SaaS layer. It holds ~48% global (and above 55% US) sleep-apnea device share, cemented when Philips exited the US market on its 2021 recall. The core hardware business (88% of revenue) is both the dominant mix and the faster grower (~11.5% YoY). Passes the oligopoly hard gate cleanly. Misses a 10 only because devices sit at ~48% (not above 50%) global share and the ~12% SaaS sliver is competitive. Weight: 35%
Sleep Apnea / Respiratory Care -- Strong, Durable Theme
Secular Tailwind -- Multi-Year Visibility
ResMed is a structural beneficiary of a massively undersupplied TAM: 80%+ of obstructive sleep apnea remains undiagnosed globally, so the binding constraint is diagnosis/awareness, not competition. That protects pricing and growth for the category leader. GLP-1 weight-loss drugs, widely feared as a substitute, are shown by management data to expand the diagnosed funnel and lift CPAP adherence — a tailwind, not a threat.
Clear #1 -- A Duopoly Turned Near-Monopoly in the Core
Oligopoly Gate: PASS
ResMed and Philips together controlled 80%+ of the global sleep-apnea device market. Philips' 2021 Respironics recall and multi-year US absence handed ResMed ~48% global / above-55% US device share and a multi-year installed-base land grab in masks. This is a ≤3-player oligopoly (ResMed + Philips ± F&P) controlling 70-80% of the core hardware market — well above the gate threshold.
Recurring Resupply Annuity -- Sticky, High-Margin
Masks & Accessories -- Razor/Blade Lock-In
Masks and accessories (~37% of revenue) are consumables tied to the installed device base — a razor/blade annuity that competitors cannot dislodge without first winning the device. Combined with clinical validation, payor/competitive-bidding entrenchment, and Philips' continued US absence, switching is slow and costly. ResMed is a price-setter in devices and masks.
Residential-Care SaaS -- Competitive, Lower-Share
SaaS (~12% of Revenue) -- The Fragmented Segment
The Residential Care Software segment (Brightree, MatrixCare) is top-tier in home-health/HME software, but it is the most fragmented part of the portfolio (top-5 vendors = ~45% of out-of-hospital software) with more competitive pricing pressure. At only ~12% of revenue it does not drive the moat — the economically dominant hardware segments are concentrated, not fragmented.

Segment / Product-Line Mix (latest reported, cal 2026Q1)
Segment / Product Line Revenue % Rev Market Position
Devices (PAP flow generators) $735.7M 51.4% ~48% global (#1; above 55% US post-Philips)
Masks & accessories $524.8M 36.7% #1 globally; ResMed + F&P + Philips ~60% of mask market
Sleep & Respiratory Care (total) $1,260.5M 88.1% ~48% device / #1 mask
SaaS (Residential Care Software) $170.9M 11.9% Top-tier; top-5 vendors = ~45% (fragmented)
Total revenue $1,431.4M 100%

The core hardware business is both the dominant mix (88%) and the faster grower: Sleep & Respiratory Care grew ~+11.5% YoY (from $1,130.6M in cal 2025Q1 to $1,260.5M), versus SaaS ~+6% YoY (from $161.2M to $170.9M).


Oligopoly Hard Gate
Criterion Result
ResMed share in core sleep-apnea devices ~48% global / above 55% US
Any segment above 30% share? Yes (devices, masks)
≤3 players controlling above 70%? Yes (ResMed + Philips ± F&P)
Customer could switch within 12 months? No — device + resupply lock-in
Gate result PASS
8/10 — A textbook "leader in a growing market" name: ~48% global / above-55% US share of the sleep-apnea device market, the #1 mask franchise, and a recurring resupply annuity, all inside a ≤3-player oligopoly that became near-monopolistic in the US after Philips' recall. The core hardware business (88% of revenue, ~11.5% YoY) is both the dominant mix and the faster-growing one, riding a structurally undersupplied TAM with GLP-1s as a funnel tailwind. It misses a 10 only because devices (51% of revenue) sit at ~48% rather than above 50% global share, theme growth is solidly above-GDP but not cleanly above 10% organic, and the ~12% SaaS segment is genuinely competitive and lower-share.
