HONG KONG, Aug. 28, 2026 /PRNewswire/ -- On August 28, Unisound (09678.HK) announced its interim results for the six months ended June 30, 2026.
The results show that the company generated revenue of RMB 562 million in the first half of 2026, up 38.7% year over year, with commercialization accelerating across the board. Token business revenue increased by approximately 760% YoY, with a gross margin of over 60%, marking Unisound's entry into a phase of accelerated large-model commercialization as it moves from technological leadership toward value leadership.
Strategic Focus on Three Core Segments, Valuation Framework Shifts Toward a Platform Model
In the first half of 2026, Unisound sharpened its strategic focus on three core segments: Enterprise AI Services, Token Business, and Edge AI. Under the new structure, the company is moving beyond the label of a traditional AI project delivery provider and transforming comprehensively into an AI platform company. The value created by AI is no longer diluted by traditional businesses, fundamentally reshaping the company's valuation framework.
All three core segments delivered solid growth:
Enterprise AI Services: Comprising agent applications, agent platforms, and industry solutions, the segment generated RMB 478 million in revenue, up 35.7% YoY, further consolidating the company's industry-leading position.
Token Business: Revenue reached nearly RMB 30 million, with second-quarter revenue increasing by more than 500% quarter over quarter, making it a new growth engine for the company.
Edge AI: Revenue reached RMB 53.8 million, up 9.2% YoY, while overseas chip shipments increased 50% YoY, demonstrating strong growth resilience.
In terms of operating quality, revenue from repeat purchases accounted for more than 60% in the first half of the year, while average customer spend increased significantly. Repeat purchases and upselling from existing customers provided further support for revenue growth. During the reporting period, administrative expenses fell sharply by 37.8%, with all savings redirected to R&D. The net loss margin narrowed by more than 31 percentage points YoY, while overall gross margin remained stable with a modest increase. As of now, total contract value in 2026 has increased 65% YoY, the order backlog has exceeded RMB 1.5 billion, and cash reserves are approaching RMB 1.0 billion, making the path to profitability increasingly clear.
Architecture Upgrade Drives Platform Transformation, U2 Enters the Global Top Tier
During the reporting period, Unisound continued to enhance its three-layer architecture of "Foundation Capability Layer - Intelligent Construction Layer - Value Operation Layer." Its agent platform, UniAgentOS, has accumulated 1,773 agent instances, with a single module reused up to 119 times. Project implementation costs as a share of total costs fell from 21% in the same period last year to 17%. The revenue model has expanded beyond one-off project delivery to include platform subscriptions, usage-based calls, and ongoing operations, further strengthening revenue continuity.
On the technology front, Unisound has continued to expand the U-Model family around U2, driving ongoing breakthroughs in general-purpose foundation models, industry-specific models, and multimodal capabilities. Across the global LLM landscape, U2 has entered the top tier in multiple challenging benchmarks, spanning long-context understanding (AA-LCR), knowledge reasoning (GPQA Diamond), instruction following (IFBench), agent execution (SWE-bench Verified), and complex tasks (WildClawBench). Its overall performance ranks among the top 25 on LLM Stats and eighth among global model providers.
Going forward, Unisound will continue to pursue its "strong foundation models, deep applications" strategy, with a greater focus on post-training. The company will continue iterating U2 as well as models for the three healthcare domains, speech, and document intelligence. Leveraging its three-layer architecture, Unisound will further increase the reuse rate of agent modules and expand into more industries and regions. In a safe, compliant, and controllable manner, it will advance intelligence to greater heights and for the greater good, creating long-term value for society.

Unisound 2026 Interim Results: Revenue Up 38.7% YoY, Token Business Surges 760%, Large-Model Commercialization Accelerates Across the Board
The $129.99 Eleva 300X covers rooms up to 250 square feet, with a main filter tested to last up to two years and an activated carbon filter that replaces independently
TUSTIN, Calif., Aug. 28, 2026 /PRNewswire/ -- Levoit today introduced the Eleva™ 300X, a smart HEPA air purifier built for bedrooms, home offices and other rooms up to 250 square feet, where it provides 4.8 air changes per hour (ACH). The $129.99 model features system-level HEPA filtration* — a fully sealed design that routes intake air through the filter and ensures removal of 99.97% of airborne particles down to 0.3 microns. The Eleva 300X is available now on Amazon and Levoit.com.
Key Facts
- Clean air delivery rate: 161 CFM (CADR) provides 4.8 air changes per hour in a 250-square-foot area for a full air refresh roughly every 12.5 minutes.
- System-level HEPA filtration: The fully sealed, system-level design eliminates internal gaps where unfiltered air could bypass the filter, so intake air passes through the HEPA Filter, capturing 99.97% of particles at 0.3 microns*.
- DuoShield™ filtration: Dual-filter design features a replaceable Activated Carbon Filter separate from the HEPA Filter — the unit's Main Filter — to allow for personalized filtration and simplified maintenance. HEPA and Activated Carbon Filters can be replaced independently, with Pet, Smoke & Cooking and Premium Activated Carbon Filter options available.
- Certifications: AHAM Verifide® and Energy Star® 3.0 certified — an Energy Star tier reached by roughly one in four room air cleaners evaluated by the EPA in 2025.
- Smart sensing: AirSight® Plus 2.0, a 3-channel laser sensor, detects PM1.0, PM2.5 and PM10 particles in real time and enables Auto Mode to adjust fan speed based off current air quality.
- Quiet, livable design: Between 20 and50 dB operation, a 9.4-by-9.4-inch footprint and display lights that can be turned off at any fan speed, including its highest.
- Low-cost upkeep: Main Filter is tested to last up to two years†, with an independently replaceable Activated Carbon Filter so only the spent filter is replaced.
- Warranty: 2-year limited warranty.
- Price and availability: $129.99 MSRP, available now on Amazon and Levoit.com.
Spokesperson Quote
"The Eleva 300X was built around a simple standard: a HEPA rating should describe the clean air an air purifier delivers to a room, not just what the filter can capture in isolation. That's why we, as the category leader, designed the Levoit Eleva 300X air purifier as a complete, fully sealed filtration system. Its system-level HEPA performance accounts for the filter, seals, housing and airflow path, helping minimize unfiltered air bypass and giving consumers greater confidence that the air returned to the room has passed through the HEPA filtration system."
— David Yoon, Director of Product Commercialization Team, Levoit
System-Level HEPA Filtration, Explained
The Eleva 300X air purifier is built as a fully sealed system, so intake air is routed through the HEPA Filter with no internal gaps for air to bypass it. That means the unit's 99.97% HEPA rating* down to 0.3 microns, reflects particle filtration of the air actually delivered back into the room, rather than a lab measurement of the filter media in isolation.
DuoShield™ Filtration System
The Eleva 300X pairs the HEPA Filter — the unit's Main Filter — with a separately replaceable Activated Carbon Filter. The included Essential Activated Carbon Filter reduces common household odors, gases, and VOCs, and can be upgraded with a specialized Pet, Smoke & Cooking or Premium Activated Carbon Filter depending on the household's needs. Choose the Smoke & Cooking Filter for wildfire smoke, cooking odors and VOCs; the Pet Filter for pet-related odors; and the Premium Filter for stronger, lingering household odors and VOCs. This technology is what allows the HEPA and Activated Carbon Filters to be replaced independently of one another, so routine maintenance only requires replacing the spent filter, not the entire filtration system.
AirSight® Plus 2.0 Smart Sensor and Auto Mode
A built-in 3-channel laser sensor, AirSight® Plus 2.0, continuously measures PM1.0, PM2.5 and PM10 particle levels. That real-time data enables an Auto Mode that adjusts fan speed to current conditions, running quietly and efficiently when air quality is good, and increasing output only when particle levels rise. Current air-quality readings and AQI, along with daily, weekly, and long-term air-quality trends, are displayed on the unit and in the VeSync app.
Quiet, Livable Design
Designed for bedrooms and other living spaces, the Eleva 300X operates between 20 and 50 dB with a compact 9.4-by-9.4-inch footprint that fits on a nightstand, shelf, or floor. Its display can be turned off at any fan speed, including its highest, allowing full-speed filtration without adding light to the room. A single circular touch panel controls power, fan speed, Sleep Mode, display lights and air-quality readings, while an easy-release button simplifies filter changes.
Energy Efficiency and Low-Cost Ownership
The Eleva 300X is Energy Star® 3.0 certified — a tier reached by roughly a quarter of room air cleaners evaluated by the EPA — with annual energy use of 145 kWh‡ and power draw up to 25.5 W. Its Main Filter is tested to last up to two years†, and because the Activated Carbon Filter can be replaced separately, routine upkeep means replacing only the spent filter rather than the whole assembly. Total cost of ownership over five years, including the purchase price, is $384.92§. The unit is backed by a 2-year limited warranty.
Smart App and Voice Controls
The VeSync app manages settings, schedules and air-quality monitoring for the Eleva 300X, with voice control available through compatible third-party voice assistants including Amazon Alexa and Google Assistant. The app's smart filter tracking measures Main Filter life based on actual usage rather than a fixed calendar and sends separate replacement reminders for the Main Filter and Activated Carbon Filters.
