What EnSilica does
EnSilica PLC is a UK-headquartered fabless semiconductor company founded in 2001 and listed on the LSE AIM market (ticker: ENSI) since 2022, with secondary trading on the US OTCQX Best Market (ticker: ENSIF) since April 2026. The company designs and supplies custom mixed-signal, RF, mmWave, and digital integrated circuits for demanding automotive, industrial, communications, and healthcare applications, employing approximately 210 engineers and staff across eight design and sales locations in the UK, Germany, Hungary, India, and Brazil. Core technical competencies include RF and mixed-signal ASIC design, ISO 26262 ASIL-D functional safety, DO-254 avionics compliance, ISO 13485/14971 medical device certification, and ISO/SAE 21434 automotive cybersecurity, supported by a proprietary IP portfolio that spans eSi-Crypto hardware cryptographic accelerators (including Post-Quantum Cryptography cores), the CHERI-enabled EnSura RISC-V secure microcontroller platform, radar processing IP, and the EN92040 Ku-band distributed beamformer IC for satellite user terminals.
EnSilica operates four interlocking revenue streams: (1) turnkey ASIC supply from concept through foundry wafer supply and OSAT packaging via partners including TSMC, GlobalFoundries, SK Keyfoundry, ASE Group, RoodMicrotec, and Unisem; (2) professional ASIC design services covering architecture, analog/mixed-signal/RF design, verification, and qualification; (3) ASSP products including satellite communication beamformer ICs and automotive/industrial standard parts; and (4) silicon IP licensing (notably eSi-Crypto). Customers include a German Tier 1 automotive components manufacturer ($75m seven-year contract), a European satellite operator ($50m+ satellite payload contracts), Siemens, SIAE Microelettronica, Vites, and a biometric sensor company, with European government funding secured from the UK Space Agency (£10.38m) and ESA NAVISP programme.
For the year ending 31 March 2026, EnSilica reported record revenue of £27.5m, up 51% year-on-year, with EBITDA turning positive at £4.7m from nil previously. The company carries a $600m sales pipeline, five ASICs in volume production with three more expected over the next 18 months, and eleven additional ASIC programs in development. Distribution combines a direct field sales force with technical sales representatives across EMEA, the US, South Korea, and Taiwan.

- Synopsys: Global EDA and IP leader with a sizable design services and ASIC implementation arm (Synopsys Professional Services). EnSilica uses Synopsys EDA tools; Synopsys represents a much larger, broad incumbent competing for the same custom-silicon design wins.
- Cadence Design Systems: Global EDA, IP and design services company and Cadence Verification Alliance partner to EnSilica. Competes with EnSilica's design services team for outsourced mixed-signal/RF and verification engagements while also supplying tools.
Direct peers
- S3 Semiconductors: Global fabless ASIC designer serving communications, industrial and consumer markets with mixed-signal and RF expertise. Directly comparable custom-ASIC/SoC services competitor (notably shared executive alumni with EnSilica).
- Sondrel: UK-listed fabless ASIC design services house offering turnkey and design-only services across automotive, AI, networking and consumer. Most direct comparable to EnSilica in size, business model (design services + turnkey ASIC supply) and target verticals.
- IC'Alps: French fabless ASIC design house specializing in mixed-signal and analog ICs for medical, automotive and industrial. Closely comparable niche custom-ASIC services business competing in the same European design-services market.
- Codasip: RISC-V customizable processor IP and design services company, partnered with EnSilica (2025) on CHERI/PQC-enabled custom ASICs. Comparable as an IP-plus-design-services peer targeting CHERI/secure silicon in automotive and critical infrastructure.
