Summary: ASR Microelectronics achieves its first profitability turnaround in semi-annual performance, marking the entry of domestic cellular baseband chips into a new cycle of scaled shipments and business model validation.
In the domestic IC (Integrated Circuit) supply chain, cellular baseband chips have always been considered one of the most challenging tracks to break through. Compared to fields such as MCU (Microcontroller Unit), PMIC (Power Management IC), and analog chips, baseband chips not only require complex communication protocol processing but also involve RF co-design, carrier certification, global band adaptation, and terminal ecosystem development. For a long time, international players such as Qualcomm and MediaTek have dominated the smartphone and mobile communication chip markets, leveraging their technological accumulation, patent portfolios, and customer ecosystems, while domestic cellular baseband chips have remained in a long-term state of catching up.
On July 23, ASR Microelectronics, a domestic cellular baseband chip company, released its semi-annual performance announcement. The company expects to achieve an operating revenue of approximately RMB 2.45 billion in the first half of 2026, a year-on-year increase of about 29%; the net profit attributable to the parent company is expected to reach approximately RMB 85 million, achieving a profitability turnaround. Meanwhile, the cellular baseband chip business generated revenue of about RMB 2.022 billion, becoming the core driver of growth.
Over the past few years, domestic cellular baseband chips have undergone a lengthy process from technological R&D and product validation to customer onboarding. The performance shift at ASR Microelectronics reflects that domestic cellular baseband technology has navigated the most difficult phase and entered a positive cycle of commercial deployment and validation.
Notably, the revenue growth did not stem from fluctuations in a single business segment, but from the sustained volume ramp-up of the core cellular baseband chip business. ASR Microelectronics disclosed that in the first half of the year, cellular baseband chip revenue reached approximately RMB 2.022 billion, a year-on-year increase of over 20%, accounting for the majority of total revenue. Among these, IoT (Internet of Things) cellular connectivity, smart terminals, and emerging 5G application scenarios became the primary sources of growth. For baseband chip companies, achieving a stable revenue scale is in itself a crucial milestone in transitioning beyond the technological validation stage.
Concurrently, profitability has shown signs of improvement. The company's overall gross margin increased year-on-year, indicating that as shipment volumes expand, product structures optimize, and the supply chain matures, the chip business is beginning to gradually reflect economies of scale.
However, after deducting non-recurring gains and losses, ASR Microelectronics still incurs a certain level of net loss. High-end smartphone platforms, global customer coverage, and ecosystem development remain shortcomings that need to be addressed.

Why does the author consider ASR Microelectronics' profitability turnaround to be of milestone significance? Because in the semiconductor industry, cellular baseband chips have always been regarded as one of the most challenging chip types to break through.
The difficulty of baseband chips lies not in performance parameters, but in the necessity to undergo carrier network testing, global band adaptation across different frequencies, terminal manufacturer validation, and long-term stability testing. Particularly in the smartphone market, a chip must cope with diverse communication environments across different countries and regions worldwide; any minor detail issue could impact the product's time-to-market.
Furthermore, communication chips possess exceptionally high software and ecosystem barriers. International players such as Qualcomm and MediaTek have long accumulated complete protocol stacks, patent portfolios, carrier relationships, and terminal customer resources. For latecomers, even if hardware specifications are comparable, substantial time must be invested in optimizing the software experience, enhancing compatibility, and gaining recognition from both upstream and downstream in the supply chain.
More importantly, the baseband chip business is a typical scale-driven industry. Developing a 5G baseband chip requires massive capital investment and years of effort, but only by achieving sufficient shipment volumes can R&D costs be amortized. Qualcomm and MediaTek can sustain investments in next-generation product R&D leveraging their massive shipments in the global smartphone market, whereas new entrants often have to endure a prolonged period of losses.

The Growth Path of ASR Microelectronics: Surrounding the Cities from the Rural Areas
Over the past few years, domestic cellular chip manufacturers have not chosen to compete directly with leading companies such as Qualcomm and MediaTek in the smartphone market.
The IoT (Internet of Things) market, with more fragmented demand and richer applications, is the primary battleground for domestic cellular chips.
A vast array of industrial equipment, smart meters, shared devices, POS terminals, security equipment, and connected vehicle terminals do not require flagship-level performance; instead, they focus more on cost, power consumption, stability, and long-term supply capabilities. This provides a breakthrough opportunity for domestic chip companies.
Currently, ASR Microelectronics is the only listed domestic cellular baseband chip company. Here, the author compares it with its closest peer, UNISOC. Since UNISOC is not yet listed, a comparison of financial data is not feasible.
Although both UNISOC and ASR Microelectronics have mastered cellular communication technologies ranging from 2G to 5G, their market positions and commercialization paths are not entirely identical. UNISOC is closer to a comprehensive mobile communication platform vendor, whereas ASR Microelectronics established its scale in the cellular IoT market before expanding into 5G broadband access and smart terminals.
UNISOC has been deeply engaged in communication semiconductors for over two decades, with products covering smartphones, IoT, automotive electronics, smart displays, and wireless connectivity. In the smartphone market, the company has formed a relatively complete 4G and 5G product portfolio, with products entering multiple global smartphone brands and carrier systems. Meanwhile, UNISOC has also deployed Cat.1, Cat.4, Cat.6, NB-IoT, 5G RedCap, and IoT-NTN satellite communication chips, attempting to replicate the platform capabilities formed by smartphone SoC (System on Chip) into a broader smart IoT market.
Instead of concentrating all resources on the fiercely competitive flagship smartphone market, ASR Microelectronics started with cellular IoT and mobile broadband products such as Cat.1, Cat.4, and Cat.6, accumulating shipment volumes and customer resources in modules, payment terminals, industrial equipment, smart wearables, and enterprise terminals.
Building on this foundation, ASR Microelectronics is upgrading to higher-value applications. Its 5G CPE products based on the ASR1901 platform have entered mass production and are deployed in Indonesia's 1.4GHz 5G FWA network; the company has also launched a RedCap platform for smart wearables, as well as the ASR8861, a 4G octa-core smart SoC integrating up to 20 TOPS of edge AI (Artificial Intelligence) computing power. Its product boundaries have gradually expanded from pure connectivity chips to a platform integrating "connectivity, computing, and edge AI." According to data disclosed by the company, its cumulative chip shipments have reached a substantial scale, with the cellular baseband business becoming the core source of revenue growth.
Domestic Cellular Baseband Chips Enter the Commercial Validation Phase
Ultimately, the most noteworthy aspect of ASR Microelectronics' recent profitability turnaround is not the RMB 85 million net profit itself, but the simultaneous emergence of expanded revenue scale, core business growth, improved gross margin, and narrowed losses for domestic cellular baseband chips after years of intensive investment. In the past, industry discussions on domestic cellular baseband chips often focused on whether tape-outs could be completed, whether complete communication standards could be supported, and whether carrier and terminal manufacturer certifications could be passed. Today, the focus is shifting to a more practical commercial level.
The author believes that after establishing a foundation in the IoT market, domestic baseband manufacturers are expanding into higher-value applications. Among these, 5G FWA (Fixed Wireless Access) has become a crucial direction. Compared to traditional IoT devices, FWA terminals require higher data transmission capabilities, stronger network stability, and more complex communication capabilities, yet they do not face the extremely high performance and ecosystem demands of flagship smartphones. Therefore, FWA serves as a vital transitional scenario for domestic 5G baseband chips to enter the mid-to-high-end market.
Concurrently, RedCap, edge AI, and smart terminals are opening up new growth spaces. As a lightweight 5G technology, RedCap can strike a balance among cost, power consumption, and performance, targeting scenarios such as industrial IoT, video surveillance, and wearable devices. As AI capabilities migrate to the edge, baseband chips are also evolving from pure "connectivity chips" to "connectivity + computing" platforms.
The smart SoC products integrating AI computing capabilities launched by ASR Microelectronics in recent years exemplify this trend. In the future, cellular chips will no longer be solely responsible for device connectivity; they will also need to simultaneously handle tasks such as local inference, data processing, and intelligent interaction.
The next two to three years will be a critical window for domestic cellular baseband chips to transition from breakthroughs in niche markets to platform-level competition.
