SG Micro, a Chinese maker of analog chips listed in Shenzhen and Hong Kong, has signed an agreement to buy 58.2878% of Shanghai Sensylink Microelectronics, a company that designs temperature, humidity and other environmental sensor chips. SG Micro announced the deal on October 26, 2026.
It will pay RMB 832.7 million (about $115 million) in cash for the stake, according to Jiemian and Sohu. The money will come from SG Micro's own funds, other money it raises and possibly proceeds from its Hong Kong share listing.
Once the deal completes, SG Micro will become Sensylink's controlling shareholder and consolidate it as a subsidiary that it does not wholly own, Jiemian reported. The purchase has been approved by SG Micro's board and does not need a shareholder vote, but it is subject to conditions and no closing date was given.
What Sensylink built
Sensylink was registered in Shanghai on February 26, 2015, according to its profile on 36Kr's PitchHub, which describes the founding team as engineers who returned from Silicon Valley together with experienced Chinese sensor researchers and sales staff. Its legal representative is Wang Yu.
The company designs environmental sensor chips that measure temperature, humidity, pressure and gas, built to be accurate, small and low on power use. It also makes mixed-signal chips such as digital interface chips and digital-to-analog converters, Sohu reported. PitchHub lists its core technologies as the sensing element, a custom analog-to-digital converter and calibration algorithms for mass production.
Sensylink has hundreds of chips in development or mass production, used in industrial equipment, networking and computing hardware, medical devices and wearables, according to Sohu.
The funding and the numbers
Sensylink raised several rounds of venture funding, according to PitchHub. It raised nearly RMB 30 million in a Series A in September 2017, followed by an A+ round from Shanghai Jinruobo in December 2018 and a Series B from Hetang Ventures in July 2019. Skyworth Group and Hushan Capital invested tens of millions of yuan in a B+ round in August 2020.
In October 2021 it raised RMB 120 million (about $18 million at the time) in a Series C with investors including Guofang Capital, Wofu Capital, Kaishi Investment, Guangzhou Minghong, Hushan Capital and Yingfu Tech. Its last reported round, a Series D in August 2022, came from Ningbo Wenqin, SMIC's investment arm SMIC Capital and Xinke Capital, with the amount undisclosed.
SG Micro is buying the stake from 27 sellers, including Shanghai Feiyu and Shanghai Jinruobo, Sohu reported. A market-based valuation put the whole of Sensylink at about RMB 1.433 billion as of June 30, 2026.
Sensylink's unaudited accounts show revenue of about RMB 240 million in 2025 and net profit of RMB 7.2 million. In the first half of 2026 it reported revenue of about RMB 150 million and net profit of RMB 14.5 million, although its operating cash flow was negative by about RMB 14.6 million.
Why SG Micro is buying
SG Micro makes analog chips for signal processing and power management. In the first half of 2026 its revenue rose 42.7% to about RMB 2.6 billion and its net profit attributable to shareholders more than doubled to about RMB 420 million, Sohu reported.
The company described the deal as horizontal consolidation within analog chips. Sensylink's products are different from but complementary to its own, so the two can be designed into the same customer projects, and SG Micro expects to share sales channels, customer relationships and supply chains, as well as quality and purchasing practices.
Sohu cautioned that those benefits still have to show up in design wins, conversion into mass production, reliable delivery and margins, and that the acquisition will create goodwill and integration risk.
How the deal is structured
SG Micro will pay the price in two equal instalments once set conditions are met. The second payment is tied to changes in Sensylink's governance and the handover of its company seals, bank accounts and internal approval rights, Sohu reported.
That structure gives SG Micro control of Sensylink's operations before the full price is paid. The remaining 41.7% of the company will stay with other shareholders, and neither company has said whether SG Micro plans to buy them out later.
