From 2022 to 2025, SG Micro's R&D investment growth significantly outpaced gross profit growth, with its product platform expanding steadily while commercial returns lagged behind. However, the first half of 2026 showed improvement in this relationship, as gross profit growth began to exceed R&D spending and the gross profit-to-R&D coverage multiple improved simultaneously. This is an encouraging sign, but whether it signals a shift from cyclical recovery to sustainable commercial returns will require confirmation across multiple future reporting periods through gross profit coverage, product ramp-up, and cash flow quality.

In the first half of 2026, the company generated revenue of RMB 2.595 billion, up 42.70% year over year. Gross profit reached approximately RMB 1.345 billion, rising roughly 47.5%, while R&D investment totaled RMB 617 million, up 21.56% from the prior year. The gross profit-to-R&D coverage multiple improved to 2.18 times from 1.80 times in the first half of 2025. Management attributes the revenue surge to the continuous launch of new products, a higher mix of premium offerings, expansion in application fields and customer bases, and completion of a multi-category product layout in markets such as optical modules, alongside growing sales of related products driven by long-standing industrial sector expertise. The technical accumulation from years of R&D and the continuously expanding product matrix are key sources of competitiveness, yet the economic value of this platform ultimately depends on whether these assets can be repeatedly leveraged, whether existing and new products can jointly enlarge the gross profit pool, and whether continued R&D investment translates into more stable cash returns.

Product matrix keeps expanding but coverage multiple has yet to trend upward

Over the past four years, SG Micro's product platform expansion has been substantial. In 2022, the company offered over 4,300 sellable products across 30 categories, covering signal chain and power management. By 2025, products had grown to more than 6,800 items across 38 categories, extending into new areas such as sensors; automotive-grade chips alone exceeded 500 models across dozens of categories. In the first half of 2026, sellable products increased further to over 7,200 items, with automotive-grade chips reaching more than 600 models.

The issue lies in the fact that product count growth has yet to fully translate into commensurate profitability gains. Between 2022 and 2025, the company's revenue stood at RMB 3.188 billion, RMB 2.616 billion, RMB 3.347 billion, and RMB 3.898 billion, respectively, with gross profit of approximately RMB 1.880 billion, RMB 1.297 billion, RMB 1.723 billion, and RMB 1.986 billion. Over the same period, R&D expenses rose from RMB 626 million to RMB 1.045 billion. The corresponding gross profit-to-R&D coverage multiples were 3.00 times, 1.76 times, 1.98 times, and 1.90 times. In short, from 2022 to 2025, R&D spending climbed about 67.01% while gross profit only grew roughly 5.62%. SG Micro's product matrix has expanded persistently, but the coverage multiple has not yet established a sustained upward trajectory.

Of course, the 3.00 times recorded in 2022 cannot be simplistically regarded as the company's normal level. That year, the semiconductor market experienced a dramatic shift from supply shortages to inventory digestion, making the supply-demand and pricing environment particularly unusual. Therefore, what truly warrants attention is not when SG Micro will return to the 3.00 times level, but whether the coverage multiple can continue rising while R&D remains funded. This is exactly why the first half of 2026 has become a key observation window. With gross profit of about RMB 1.345 billion and R&D investment of RMB 617 million, the coverage multiple improved to 2.18 times, up from 1.80 times in the same period last year. The product platform is at least beginning to show signs that earlier investments are being monetized faster. However, whether this stems from maturing platform capabilities or is merely a cyclical rebound from industry recovery requires a closer look.

Gross profit improvement is not solely about selling more high-margin products

In 2025, the company's signal chain product revenue reached RMB 1.471 billion, up 26.23% year over year, with gross margin at 58.17%, roughly flat. Power management revenue was RMB 2.380 billion, up 9.08%, but gross margin fell 1.43 percentage points to 46.38%. By the first half of 2026, both product categories accelerated noticeably, though with divergent performance. Signal chain revenue came in at RMB 1.036 billion, up 53.13% year over year, with gross margin down 1.89 percentage points to 57.11%. Power management revenue reached RMB 1.521 billion, up 35.45%, with gross margin up 3.32 percentage points to 47.97%. The company's overall gross margin hit 51.84%, an improvement of 1.68 percentage points year over year.

In the first half of 2026, signal chain revenue growth outpaced power management, and the higher weight of signal chain with its higher gross margin positively influenced the blended margin. Yet this is not the entire explanation. During the same period, signal chain gross margin contracted by 1.89 percentage points while power management gross margin expanded by 3.32 percentage points. This suggests that the blended margin improvement was simultaneously driven by product mix shifts and margin changes within each category. The current disclosures are insufficient to further decompose the contributions of pricing, model structure, and cost changes. This is also a key factor in assessing platform value in the next phase. If revenue growth still requires concessions on price and margin, an increase in product count may not significantly boost R&D productivity. Conversely, if more existing products enter customer mass production and mature technologies are applied across multiple new products, reducing the marginal R&D and customer acquisition costs needed to generate incremental revenue, then the foundation for a sustained rise in the gross profit-to-R&D coverage multiple will be established.

From ADC to optical modules: technical progress enters the validation phase

SG Micro's R&D efforts go beyond mere additions to the product catalog. A representative example is its high-precision ADC/DAC portfolio. In the 2022 annual report, the company disclosed that some high-precision analog-to-digital and digital-to-analog converters had entered small-batch production, with upgraded versions still under development. By 2025, relevant projects had evolved across multiple architectures including SAR, Delta-Sigma, and Pipeline, with several product series achieving mass production while advanced versions continued to be developed. In the first half of 2026, the company launched additional products including an 18-bit 2MSPS ADC, a 16-bit 3MSPS SAR ADC, an 8-channel 24-bit Sigma-Delta ADC, an automotive-grade 16-bit ADC, a 4-channel 16-bit DAC, and a 120V 16-bit high-precision digital power monitoring AFE. The progression from small-batch samples of select products to mass production of multiple series, and onward to continuous expansion across architectures and applications, at minimum demonstrates that R&D investments made years ago are indeed materializing into more complete product families. Yet technical progress still cannot be equated with commercial returns.

The same applies to automotive-grade products. The increase from over 500 models to more than 600 demonstrates expanding supply capability, certification coverage, and product breadth, but it does not directly prove that end customers have established large-scale, recurring procurement. What truly matters is whether these products have moved from certification and sampling into vehicle mass production, and whether they subsequently gain adoption across more vehicle models or more functional slots within the same customer. Optical modules may offer another pathway to validate the platform. In the 2026 interim report's explanation of revenue changes, the company explicitly cites "completing a multi-category product layout in markets such as optical modules and achieving comprehensive customer coverage" as one of the drivers of revenue growth. This is more analytically meaningful than vague discussions of AI trends. If the "multi-category product layout" implies that multiple product series can be introduced to the same customer or application, then a single customer win could trigger orders across several product lines, generating recurring returns. However, the annual report does not disclose optical module segment revenue or specific customer purchase amounts. For now, it can only be confirmed that the company claims business progress in this area, but its contribution to 2026 revenue growth cannot yet be quantified.

Cash and inventory serve as the second test of commercial returns

In 2025, SG Micro's revenue grew 16.46%, yet net operating cash flow fell 15.11% year over year to RMB 466 million. By year-end, accounts receivable had climbed from RMB 233 million to RMB 362 million, and inventory rose from RMB 1.165 billion to RMB 1.448 billion. The company also recognized RMB 170 million in asset impairment losses, primarily from inventory write-downs. The first half of 2026 showed improvement. Net operating cash flow reached RMB 382 million, up 59.28% year over year, which the company attributes to higher revenue and increased collection of sales proceeds. However, inventory in absolute terms continued to rise. At the end of June, inventory book value further increased to RMB 1.677 billion, and accounts receivable rose to RMB 450 million. Notably, the book balance of finished goods remained nearly flat at approximately RMB 688 million versus RMB 687 million at the start of the year, but the provision for finished goods inventory write-downs rose from RMB 193 million to RMB 222 million. At the same time, the book balance of raw materials increased from RMB 837 million to RMB 1.055 billion. In other words, the increase in inventory during the first half of this year came primarily from raw materials and work-in-progress, rather than a large accumulation of finished goods. This is consistent with business expansion and stocking up for production, but it still needs to be validated by future sales. If downstream demand materializes, the added raw materials can be converted into sales and cash collections. If sales fall short, they may further accumulate as work-in-progress or finished goods, creating downward pressure on valuations.

2026 improvement still requires validation across multiple reporting periods

SG Micro is at a stage where it has moved beyond simply expanding R&D and the product matrix, with signs that earlier investments are beginning to translate into gross profit more quickly. However, whether a sustainable platform-return mechanism has truly formed still lacks sufficiently long financial and operational evidence. Moving forward, it remains necessary to monitor whether gross profit growth can continue to outpace R&D investment, whether the coverage multiple keeps improving without any cutback in R&D spending, whether the gross margin decline during rapid signal chain growth converges, whether the power management margin recovery persists, whether high-precision converters, optical module products, and automotive-grade offerings witness sustained downstream order validation, and whether operating cash flow, accounts receivable, inventory, and impairment losses remain aligned with profit growth. If revenue and profits merely recover in tandem with the industry cycle, without product realization and cash quality improvement, the conclusion should remain at cyclical recovery. Only when gross profit coverage continues to rise, multiple product series enter scale applications, and inventory risks remain contained can the assessment of platform commercial returns be upgraded.
