Sentry Aerospares, a Watford, England-based portfolio company of aerospace-focused private equity firm Acorn Capital Management, announced on July 7, 2026 the acquisition of AirStart Inc., a leading independent stocking distributor of rotable aircraft components with a strong focus on regional platforms and a recognized leader in the Canadian market. The release presents the transaction as completed upon announcement, indicating both an announce and close date of July 7, 2026. Terms of the transaction were not disclosed; because no transaction value was published, no Canadian dollar equivalent can be calculated or provided.

Founded by Rob Wills, AirStart specializes in the exchange and leasing of rotable parts for commercial aircraft, with expertise across ATR, De Havilland Q400, MHI CRJ and Embraer platforms. Its state-of-the-art facility adjacent to Toronto Pearson Airport complements Sentry's existing global hubs in London, the New York metro area, and Dallas, enhancing 24/7 aircraft-on-ground (AOG) service. The deal is expected to generate cross-selling synergies and broaden Sentry's regional aircraft inventory and customer base.

On advisors, Proskauer Rose LLP served as primary legal counsel to Acorn and Sentry, while Deloitte Corporate Finance Inc. acted as exclusive financial advisor and McMillan LLP as legal counsel to AirStart's vendors. As a private M&A transaction rather than a securities offering, the document identifies no underwriters, agents, or dealers.
