Sepura

What Sepura does

Sepura is a UK-headquartered, privately held designer and manufacturer of digital radio communications equipment for mission-critical and business-critical operations, with its headquarters and 150-person R&D centre at Cambridge Research Park. The company's core technology is TETRA (Terrestrial Trunked Radio), a standards-based narrowband voice and data standard widely used by public-safety and infrastructure operators, complemented by a hybrid TETRA and 4G/5G product line (SCL3 hand-portable and SCU3 vehicle device) intended to enable customers to migrate at their own pace toward Mission Critical Services (MCX). Sepura's product portfolio spans rugged hand-portable radios (SC20, SC21, SC23, STP8X000), vehicle radios (SCG22, SCU3), ATEX/IECEx-certified devices for explosive atmospheres, an extensive accessory ecosystem, the AppSPACE applications platform (RadioAsset, AutoMate, SmartView, Shunting Call), and centralised device management software (Radio Manager 2, Sepura Device Manager).

The business sells almost exclusively through a global network of more than 100 authorised partners, generating revenue primarily from hardware sales with a growing contribution from device-management software subscriptions and professional services such as training, repair and maintenance. Sepura's installed base exceeds 3 million devices across 100+ countries, with market leadership positions in more than 30 countries and a customer base concentrated in public safety (police, fire and rescue, ambulance, covert surveillance), transportation (airports, railways, metros, ports), energy and mining, and commercial verticals. The company was acquired by UK private equity firm Epiris in 2022 via a management buyout led by then-CEO Steve Barber; in October 2025 Chris Barnes succeeded Barber as CEO as part of a planned succession. Historical acquisitions include Teltronic (2015, infrastructure and terminals), Portalify (2013), Fylde Micro (2014) and 3t Communications (2012).

• Thales: Global defense and aerospace group with critical-communications offerings (infrastructure, terminals, secure networks). Competes with Sepura in transportation and public-safety infrastructure deals.

Direct peers

• Motorola Solutions: Global incumbent in mission-critical communications. Directly competes with Sepura across TETRA terminals, hybrid LTE devices, and command-and-control software, and is Sepura's co-contractor on the UK Airwave extension.
• Hytera: Chinese-headquartered supplier of TETRA and PMR/LTE professional mobile radios. Direct competitor across public-safety, transportation, and utilities verticals, particularly strong in Asia, EMEA and Latin America.
• JVCKENWOOD (Kenwood Professional Radio): Major manufacturer of professional and mission-critical hand-portable and mobile radios (NEXEDGE, DMR, PTT over LTE). Overlaps with Sepura in transportation, utilities, and public-safety segments.
• Codan Communications (Barrett Communications / Zetron): Supplies HF, critical-communications, and dispatch solutions to defense, public safety, and humanitarian markets. Comparable in mission-critical voice communications and rugged terminal design.
• Icom Incorporated: Japanese professional radio manufacturer with a broad PMR/LTE portfolio including LTE/PTT handhelds targeted at public safety and industrial users. Comparable in product category and ruggedized device positioning.
• Airbus (Public Safety and Security / Cassidian): Supplies TETRA infrastructure (e.g. Tetrapol, TETRA networks) and partner terminals into European and Middle Eastern public-safety networks. Competes with Sepura at the network/device interface in shared customer accounts.

Emerging players
