Momentum Group AB is a Swedish industrial group listed on Nasdaq Stockholm under MMGR B, headquartered at Östermalmsgatan 87 E in Stockholm. It acquires and operates Nordic companies supplying industrial components and related technical services, organised into two business areas: Components, built around Momentum Industrials AB, which supplies spare parts for industrial production equipment, and Services, built around Rörick Elektriska Verkstad, which provides electromechanical repair and servicing. Ulf Lilius is President and Chief Executive Officer and Johan Sjö is Chairman. The group employs roughly 950 people.

The company was listed in 2022 when the former Momentum Group AB renamed itself Alligo AB and spun off its Components & Services business area as a separate listed company retaining the Momentum Group name. It operates as a serial acquirer: six acquisitions in the first half of 2026 added combined annual revenue of about SEK 230 million. Net sales for the first half of 2026 were SEK 1,622 million, up 4%, with EBITA of SEK 183 million at an 11.3% margin.
