Midea Group (0300.HK) – Can One Sold-Out Air Conditioner Move the Valuation Needle?
European heatwaves, PortaSplit, and one underrated globalization story
This June, Europe got hot again.
It’s one of France’s hottest-ever June days since 1947. Germany’s household AC penetration JUST crossed 13% to 19%. UK homes with AC have doubled in three years.
While news feeds were full of Northern hemisphere humidity, one Chinese brand popped up again and again in German, French, and English forums. Weirdly, it wasn’t advertising. People were searching everywhere for it. And ***could not buy it. ***
Meet Midea’s latest air conditioner innovation, PortaSplit. You can’t drill holes to install it. No sweaty professional installers. The outdoor unit hangs quietly on your window bracket. It went to zero inventory across 1,178 tracked German retail channels. Secondhand prices hit double the retail tag. Fake websites impersonating Midea’s official store popped up. Google Trends showed German searches for “Midea Split” running at roughly six times last year’s peak.
Behind this sits a much bigger narrative about European AC penetration rates, Chinese manufacturing going global, and a potential rerating of a conglomerate’s valuation.
Europe’s “Installation Friction” Problem
Europe isn’t underserved because people enjoy sweating through summer. Under IEA’s definition, European households owning AC hover near 20%, versus the US, Japan, or China. It’s mostly friction: you can’t drill your apartment walls. Landlords don’t allow it. The homeowners association might let you but not where you want to place the outdoor unit. Then you find out all installers have a weeks-long wait. And F-gas regulations require certified technicians to handle refrigerant systems.
Traditional portable ACs are noisy, inefficient, and leak hot air back through their exhaust hoses.
PortaSplit cracks the package.
Mount the compressor outside. Keep the evaporator + fan assembly indoors. Run a flat 2.7cm refrigerant hose through the window. Close your window almost all the way. Enjoy 39dB(A) noise levels indoors. No certified tech required. Go drill-free. Landlord approval? It’s not the most “legally invisible” option — there’s still a small outdoor unit on the windowsill. But it may offer the best ratio of cooling performance to installation friction available to consumers today.
Air conditioner shopping is a pain point. Comment threads on r/MideaPortaSplit don’t discuss specs, they share life hacks. How do I keep my attic apartment cool? How can I protect my aging parents during summer spikes? Does it seal on sliding windows? The building manager demands removal. Is Slovenia my only hope to find stock left? ?
Got told by living roommates you couldn’t install it? Fabricate foam sealing boards to seal off window gaps. Cross the border to Slovenia JUST to hunt for leftovers. Pay €1000 for boxed unused resale.
This kind of spontaneous user ecosystem is harder evidence of product-market fit than any commissioned market study.
How much profit can ONE AIR CONDITIONER really drive?
It feels like this should move margins this quarter. Algebra says it can’t.
Revenue for Midea Group in 2025 was RMB 458.5 billion. Net profit attributable to shareholders was RMB 43.95 billion.
The Smart Home segment contributed about RMB 300 billion of that revenue alone, and accounts for a lion’s share of Group profit.
Even if PortaSplit sells several hundred thousand units across Europe, with Midea recognizing perhaps RMB 4,000–5,500 per unit, total revenue contribution lands somewhere between RMB 1–2 billion. For a group this size, that’s a highlight, not a transformation.
What matters isn’t unit volume this year (or next). It’s what PortaSplit proves.
If Germany (19%), France (25%), UK (14%) converge to something closer to Italy’s (56%) household ownership rate, that 8-country basket represents ~50-58 MILLION households needing air conditioning. 60-80 million units. Cumulative manufacturer-level revenue of RMB 2–5 trillion. Not a one-year story.
But it does change the question: Is Group AC “doing business overseas” cyclically-export driven, or do we start treating penetration-rate uplifts AS structural growth?
Smart Home: Not Cheap Appliance Stock. Not Yet Premium Brand.
Assessing Midea begins with Smart Home.
Smart Home represents about 70% of the groups aggregate operating asset value.
Last year’s segment profit was ~37.1 billion on gross margins of ~30%+. Overseas business represented ~50% of total revenue. Overseas OBM take RATE for Smart Home passed 45%.
OBM exceeding 45% of overseas Smart Home revenue is THE metric of the past five years. It’s what that reclassifies Midea from another white-goods contract manufacturer to a trusted brand consumers actually buy MIDEA branded appliances from. Sure, they stock Toshiba. Sure, they make compressors for fridge brands you’ve heard of. But Midea is catching up. Brand is being built. On their own channels. Serving their own after-sales users.
Revenue recognition on Air Conditioners is immaterial to asking how much of this business is structurally sticky.
Keeping that in mind, we still can’t just take RMB 37.1 billion and multiply by 15. Supportive industry policies massively skewed year-on-year growth.
Trade-in subsidies spanned 12 categories. “Top tier product purchases” (highest energy efficiency) earned consumers purchase price subsidies of up to 20%. Air conditioners qualified for up 3 purchases per household.
China finished the year with over 129 MILLION traded-in appliances.
Needless to say, 2025 demand was redistributed forward. Whichever brand benefited most from subsidy-driven uplift will see service fade quickly as high-efficiency penetration climbs toward saturation. Channel execution will only get tougher.
After adjusting for policy tailwinds, elevated margins, and cyclical factors, normalized owner earnings land around RMB 26.5–28.0 billion.
What is that worth?
Domestic China is a mature cash cow — high-end upgrades and channel efficiency might add one to two percentage points annually. Overseas OBM is the real engine: if the share climbs from 45% toward 55–60%, profit growth can outpace revenue growth. Europe and PortaSplit are optionality — the demand signal is validated, but the absolute base is still small. Blended together, owner earnings growth over the next five years is probably around 4–5%, which at a 10% discount rate and 2.5% terminal growth implies roughly a 15x owner earnings multiple.
My math comes out to an owner earnings multiple of roughly 15x. That puts Smart Home at just over RMB 400 billion, or approximately HK$460–470 billion.
Building Tech is the real second act
Split off Smart Home, what’s left?
Building Technology covers commercial HVAC, building energy management, heat pumps, chillers, data center cooling, and elevators. Revenue hit RMB 35.8 billion in 2025, up 25.7% year-on-year, BUT that includes consolidation of Arbonia Climate, a European HVAC platform acquisition worth roughly EUR 760 million in enterprise value. Stripping out M&A, organic growth was still high single digits to low double digits. Gross margin clocks in at 30.6%, which actually exceeds Smart Home’s. Aftermarket service revenue surpassed RMB 2 billion while doubling year-on-year.
Not the biggest business. But if management discourse around HVAC “full lifecycle ops and maintenance,” building energy management, as a SERVICE wins out over selling equipment, I want in. Sell equipment? I’ll give you a 12x enterprise multiple. Service install-hooks on the world’s buildings? That’s an operating infrastructure platform with incredible upsides.
Valuing at 20x after-tax op profit, something more appropriate for sticky software recurring revenue streams, gives Building Technology ~RMB 75 billion enterprise value.
Midea Industrial Technology
The GMCC/Welling compressor and motor platform, plus NEV thermal management components and robotics parts. It holds the global number-one share in residential AC compressors, AC motors, and washing machine motors.
Gross margins are only 17.5%, capital expenditure runs heavy, and growth requires continuous capacity investment. It’s a “hidden champion” manufacturer — solid quality, but not a high-ROIC compounding asset. Stick 12–13x on this and we get roughly RMB 53 billion.
KUKA/Robotics
KUKA brought in nearly RMB 40 billion in revenue last year. But EBIT margin was just 1.5%, with an after-tax loss.
China is the bright spot — shipments exceeded 32,000 units, market share reached 9.6%, and its share in heavy-payload robots above 300kg hit 47.4%. But European costs are high, systems integration projects create margin volatility, and automotive capex is cyclical.
It’s not a cash cow; it’s more like a “hard brand, soft margins” turnaround asset plus an AI/robotics strategic option.
Using a probability-weighted payoff approach — base industrial value around RMB 250–300 billion plus RMB 150–200 billion in option value for AI-driven robotics — the total comes to roughly RMB 45 billion.
What Is This Company Actually Worth?
Smart Home at roughly RMB 400 billion, Building Tech at RMB 75 billion, Industrial Tech at RMB 53 billion, KUKA at RMB 45 billion. The total is approximately RMB 580 billion, or about HK$670 billion, implying roughly HK$88 per share for the H-share listing 0300.HK.
Conclusion
The stock currently trades around HK$80. This means the market is pricing a “mature appliance leader plus normal non-core businesses” narrative, without yet paying much of a premium for the European AC S-curve, Building Tech as a genuine second pillar, or a KUKA turnaround.
If Smart Home were rerated from 15x to 18x — which requires visible improvement in overseas OBM profitability and proof that European channels and branding are sustainable — Smart Home alone would be worth RMB 480–500 billion, pushing per-share value from HK$88 past HK$100.
If you’re looking for a “no-brainer price” — roughly half of expected value, where you don’t need any thesis to play out and are protected purely by cash flow floor and margin of safety — that’s around HK$45–50. At HK$80, the stock isn’t expensive, but it’s far from “close your eyes and buy.” It’s priced for believers in continued overseas OBM delivery and Building Tech execution.
The real nonlinearity doesn’t come from selling a few extra tens of thousands of PortaSplits this year. It comes from three things happening simultaneously: European consumers start treating air conditioning as a household necessity, Midea captures a high share of first-time buyers through its own brand, and the market re-categorizes Smart Home from “mature Chinese white goods stock” to “global climate adaptation beneficiary.” If all three come together, what changes isn’t EPS — it’s the valuation multiple.
PortaSplit selling out is not an investment thesis by itself. But it is an exceptionally high-quality signal: given the right product, the right pain point, and the right timing, a Chinese manufacturer can command brand premium in developed markets. That’s the thing worth tracking over the long term.
