3 Small-Cap Semiconductor Stocks Beyond Syrma, Kaynes, MosChip and ASM Technologies

RIR Power Electronics, Cyient DLM and SPEL Semiconductor offer different routes into India’s expanding semiconductor and electronics manufacturing ecosystem.

Mumbai, September 21, 2026 — India’s semiconductor investment cycle is moving beyond chip fabrication into power semiconductors, electronics manufacturing, packaging and the broader design-to-manufacturing ecosystem. With SEMICON India 2026 putting the domestic chip supply chain firmly in focus, investors are also looking beyond the better-known names such as Syrma SGS, Avalon Technologies, ASM Technologies, CG Power, Kaynes Technology and MosChip.

For investors specifically looking for smaller companies with semiconductor or semiconductor-adjacent exposure, three names stand out for further research: RIR Power Electronics, Cyient DLM and SPEL Semiconductor.

These are very different businesses and risk profiles, so the semiconductor theme alone should not be treated as an investment thesis.

RIR Power Electronics: RIR Power Electronics is the most direct small-cap semiconductor manufacturing play among the three. Formerly known as Ruttonsha International Rectifier, the company manufactures power semiconductor devices and has been in the business since 1969.

Its market capitalisation was about ₹1,581 crore on September 18, 2026, putting it firmly in the small-cap territory. The stock closed at around ₹199.

The company’s recent operating numbers provide a reason to track the business. For the quarter cited by Livemint, revenue rose 22.05% sequentially to ₹25.64 crore, while operating profit doubled to ₹5.18 crore and profit after tax rose 126.5% to ₹4.23 crore.

The catch is valuation and volatility. At roughly ₹1,500–1,600 crore market capitalisation, the stock is still a relatively small business, while the reported trailing valuation is high. The shares have also remained well below their 52-week high of ₹388.10.

Theme: Power semiconductors

Risk: High

Why watch: Direct semiconductor exposure + small base + improving recent quarterly profitability

Cyient DLM: Cyient DLM is not a pure semiconductor manufacturer. Its exposure comes through electronics manufacturing and design-led manufacturing, making it a broader semiconductor/electronics ecosystem play.

The company reported FY26 revenue of ₹1,261.5 crore and normalized EBITDA of ₹130.2 crore, with EBITDA margin improving to 10.3%. Its Q4 revenue was ₹369.1 crore.

More recently, the company’s September-quarter numbers showed operating profit of ₹20.63 crore and PAT of ₹32.14 crore, although revenue was down year-on-year.

The important caveat is that its market capitalisation has expanded sharply. At about ₹7,468 crore as of September 18, it is considerably larger than RIR and is closer to the upper end of what many investors would consider the small-cap universe.

Its attraction is therefore different: rather than betting on one semiconductor product, investors are getting exposure to the expanding electronics manufacturing ecosystem.

Theme: Electronics manufacturing/semiconductor supply chain

Risk: Moderate-high

Why watch: Larger revenue base, design-led manufacturing exposure and improving profitability

SPEL Semiconductor: SPEL is the purest semiconductor packaging story in this list and consequently also the most speculative.

The company is involved in semiconductor assembly and packaging, giving it direct exposure to India’s push to develop domestic semiconductor packaging capabilities.

Its market capitalisation was around ₹639 crore in September 2026.

However, the financial numbers demand considerable caution. SPEL reported only ₹0.08 crore of revenue in the June 2026 quarter and a net loss of ₹1.34 crore. In the subsequent quarter, revenue was ₹1.53 crore and the company reported a ₹12.47 crore net loss.

That makes SPEL fundamentally very different from an established profitable semiconductor business.

The attraction is its tiny market capitalisation and direct packaging exposure; the risk is that investors are essentially paying for potential rather than demonstrated earnings.

Theme: Semiconductor packaging

Risk: Very high/speculative

Why watch: Smallest market cap + direct semiconductor packaging exposure

The larger semiconductor story is clearly gaining policy and investment momentum. SEMICON India 2026 brought more than 600 companies from 52 countries to New Delhi, while Applied Materials announced plans to invest $5 billion in India over the next decade.

But that does not mean every small-cap semiconductor stock will benefit equally.

For investors looking beyond the established names, RIR offers the most direct power-semiconductor exposure, Cyient DLM offers a broader manufacturing route into the electronics ecosystem, while SPEL represents a much higher-risk packaging turnaround thesis.

The key variables to monitor are order visibility, capacity utilisation, customer concentration, operating cash flow, debt, capex execution and whether semiconductor-related revenue actually begins translating into sustainable earnings.

(This is a thematic market analysis, not a recommendation to buy or sell any security. Small-cap semiconductor stocks can be highly volatile and should be evaluated against valuation and financial results rather than the sector narrative alone.)
