Tempest Security AB (publ) (TSEC.ST) Stock Analysis & Winston Score
Tempest Security AB is a Swedish security services company that provides physical guarding, alarm response, and security consulting to businesses and public-sector clients across the Nordic region. The company employs trained security personnel who protect properties, events, and facilities for customers such as retailers, property owners, and government organizations. It operates in a fragmented but competitive market for outsourced security services in Sweden and nearby countries. The company earns revenue primarily by billing clients for hours of security personnel deployed, making it a labor-intensive, contract-based business. With a market cap of roughly $0.1 billion, Tempest is a small player competing against much larger firms like Securitas and G4S, which limits its pricing power and scale advantages. The operating margin is currently negative, meaning the company spends more than it earns from operations, and the key challenge going forward is improving cost efficiency and winning larger, longer-term contracts to reach sustainable profitability.
