Espressif Systems, the chipmaker behind the ESP32 family that powers countless DIY sensors, smart plugs, and low-cost connected gadgets, has reported a strong third quarter. Revenue rose 33.38% year over year to 889.28 million yuan, while net profit attributable to shareholders jumped 89.35% to 218.70 million yuan, according to the company’s third-quarter report published on the Shanghai Stock Exchange on October 24.
The headline numbers tell only half the story, though. Buried in the same report is a candid read on the smart home market itself: demand from smart home customers was, in the company’s words, only “relatively stable.” Growth came from elsewhere. For anyone building or buying smart home gear, that split — a booming chip business, a merely steady smart home market — is worth understanding.
The numbers behind the quarter
For the first nine months of 2026, Espressif’s revenue reached 2.37 billion yuan, up 23.94% from the same period a year earlier. Gross margin for the period stood at 49.97%, and research and development absorbed 21.87% of revenue — a heavy R&D load that reflects how much of the company’s bet sits in new silicon rather than in selling more of the old kind.
Geographically, the growth was broad-based but uneven. Sales in China grew 38.5% in the quarter, while sales outside China grew 23.1%. The company did not break out smart home revenue separately, but its characterization of that segment — “overall demand in the smart home industry was relatively stable, while applications outside the smart home kept growing well” — is the clearest signal in the report about where its momentum is coming from right now.
One more line deserves attention: operating cash flow trailed profit in the quarter. Espressif attributed that to a deliberate decision to build up inventory, taken “with prices of some key raw materials expected to rise.” In other words, the company is buying components now because it expects them to cost more later.
Why an ESP32 earnings report matters to your home
If you have never heard of Espressif, you almost certainly own its silicon. The ESP32 is one of the most common Wi-Fi and Bluetooth chips in maker projects and in many budget smart home devices, and it is the hardware backbone of ESPHome, the open-source firmware that lets Home Assistant users build their own sensors, switches, and controllers. ESPHome’s October 2026 release, which added compressed over-the-air updates and a browser-based device builder, runs on ESP32 hardware.
Espressif’s newer chips are also directly relevant to the Matter transition. The ESP32-C6 pairs Wi-Fi 6 with an 802.15.4 radio for Thread and Zigbee, making it a natural fit for battery-powered Matter-over-Thread sensors, while the ESP32-H2 is built specifically for Zigbee and Thread end devices. When Espressif talks about the IoT market moving from “connectivity-driven” to “function-driven” competition, it is describing exactly this shift: the radio alone is no longer the selling point — what the device does with it is.
From connectivity to features
Espressif named that shift as the first reason for its improved gross margin. The company’s framing is blunt: the IoT industry “has moved from a ‘connectivity-driven’ stage of price competition to a ‘function-driven’ stage.” In plain terms, the race to sell the cheapest connected chip is giving way to a race to sell chips that do more — on-device AI, better power efficiency, richer peripherals.
That matches what is visible on store shelves. The smart home devices drawing attention in 2026 tend to win on capability rather than on simply being connected: cameras with on-device person detection, thermostats with room-by-room control, sensors that track presence rather than just motion. Espressif’s product push in the same direction — including its ESP-Mosaico modular AI development platform built around the newer ESP32-S31 — fits the same pattern.
For buyers, the practical implication is encouraging. If chipmakers are competing on features instead of racing to the bottom on price, the floor for what a budget device can do should keep rising, even if the cheapest devices stay cheap. The risk is the opposite one: more capable silicon can also mean more features locked behind subscriptions or app ecosystems, so the specs that matter most remain local control, open standards support, and Matter compatibility.
The stockpiling signal
Espressif is not the only supplier building inventory. Quectel, the Shanghai maker of cellular IoT modules, reported third-quarter revenue up 34.89% to 8.54 billion yuan on October 20 and likewise said it had stepped up raw material stockpiling to secure production and supply-chain stability, pushing its nine-month operating cash flow to negative 1.86 billion yuan.
Meanwhile, two other Chinese chip designers pointed the other way on costs. Goodix, reporting on October 23, said third-quarter revenue fell 17.37% to 1.05 billion yuan, “mainly because rising memory prices held back demand for end devices to some extent,” and Bestechnic cited rising upstream memory chip prices alongside weak consumer electronics demand. Memory goes into nearly every connected device, so if memory prices stay high, some of that pressure eventually reaches device prices — even while Espressif and Quectel buy ahead to cushion it.
None of this means a shortage is imminent, and none of these companies is forecasting one. But two large suppliers stockpiling at once, plus two others blaming memory prices for softer demand, is a pattern worth watching through the holiday quarter, when device makers place their biggest component orders of the year.
What to watch next
Three things will show whether this quarter was a blip or a trend. First, whether smart home demand firms up in the fourth quarter, when holiday sales typically lift device shipments. Second, whether Espressif’s “function-driven” bet shows up in shipping products — more Matter-over-Thread devices built on its newer chips, and more on-device AI features that work without a cloud round trip. And third, whether component costs stay contained: if memory and raw material prices keep climbing, the industry’s stockpiling will look prescient; if they ease, it will look like a cautious quarter.
For now, the takeaway is measured. The company that makes the chips inside a large share of the smart home is doing very well — just not primarily because of the smart home. The market it serves is maturing past the point where merely adding Wi-Fi counts as innovation, and the next round of competition will be fought on what devices can actually do. That is good news for anyone tired of gadgets that connect easily and do little.
