### PC·가전·차량 (이더넷·오디오·Wi-Fi 칩) (high)
- note: Realtek is the 'invisible default' of PC connectivity — its RTL Ethernet controllers and ALC audio codecs ship onboard in the majority of the world's motherboards and laptops. That ubiquity is a volume cash cow, but commodity ASPs mean it rides the PC cycle, with value migrating toward multi-gig and USB4. 2024 revenue NT$113.4bn (+19.1%) and net profit +67.1% as post-inventory-correction recovery met a richer mix.
- [mentions] MarketScreener (EN, research, published 2026-06-01) https://www.marketscreener.com/quote/stock/REALTEK-SEMICONDUCTOR-COR-6491504/consensus/: "16-analyst consensus 'Buy' — though the 2026 stock (+73.7%) outran the target range (avg ~NT$577), pre-pricing the AI-networking narrative."
- [confirms] DigiTimes (EN, news, published 2026-01-28) https://www.digitimes.com/news/a20260128PD239/2025-realtek-revenue-growth-earnings.html: "Realtek 2025 revenue $3.8B."
- [confirms] Realtek Semiconductor (EN, filing, published 2025-05-31) https://www.realtek.com/images/ar/2024_Annual_Report_.pdf: "2024 consolidated revenue NT$113.4bn (+19.1%), gross profit NT$57.16bn (~50% GM), net profit NT$15.29bn (+67.1%, EPS NT$29.82). Ranked #7 among global IC design (fabless) firms per Omdia."
- [mentions] ICN Magazine (KO, news, published 2021-06-01) https://icnweb.kr/2021/48081/: "Realtek launched 2.5G Ethernet controllers and Wi-Fi solutions — a standard-component position in PC/networking."

### 네트워킹·통신 인프라 (스위치·라우터·PON·Wi-Fi 7) (high)
- note: Realtek's growth engine — the climb up from cheap PC codecs. It supplies telecom operators and OEMs with 2.5/5/10GbE PHYs and controllers, 24/48x10GbE campus switches, 25G PON and Wi-Fi 7. AI traffic and multi-gig LAN upgrades raise ASP and widen the TAM beyond the PC, so the more the mix shifts here, the more gross margin improves.

### 자동차 OEM·Tier1 (차량용 이더넷·오디오) (mid)
- note: A higher-value, long-duration axis — 2.5GBASE-T1 automotive Ethernet PHYs and integrated switches, plus a smart-audio DSP with a neural-network accelerator (ALC5575). As cars become networked, design-wins accrue as multi-year revenue annuities — a longer-cycle growth path than PCs.
