What AP+M does
AP+M (operating as AP4) is a private, independent stocking distributor of heavy-duty and aeroderivative gas turbine parts and control system components, founded in 1989 and headquartered in Boynton Beach, Florida. The company operates as an authorized distributor for select OEM parts across multiple platforms — GE LM Aeroderivative and Heavy Duty Frame turbines, Alstom, Siemens, and Rolls-Royce — and covers control systems spanning GE Speedtronic Mark II through Mark VIe, ABB, Alstom, and Emerson Ovation. AP+M is organized under the AP4 Group, LLC holding structure with multiple wholly-owned brand entities including GTC Control Solutions (controls parts, repair, and field services), HUGHES Technical Services, TC&E, and Maine Automation.
The portfolio combines parts distribution (ancillary parts, fuel system parts, consumables, control cards, I/O packs, and capital parts) with four service verticals: Parts and Repair (including the registered trademark Outage in a Box® bundled outage offering), Controls Solutions (field services for turbine controls, excitation, and LCI; controls component repair; controls training; and control system projects and retrofits), Turbine Services (commissioning, mechanical field services, component repair, and capital parts), and Installation Services. Field services are deployed on-site at customer facilities for controls, excitation, LCI, mechanical work, and commissioning, supported by in-house component repair capability.
AP+M generates revenue through one-time parts sales and professional services (component repair and field/engineering services) under a quote-based pricing model with no publicly disclosed tiers. Customers browse the online parts catalog, add items to an inquiry cart, and receive pricing and delivery estimates through direct sales engagement; field services and repair are similarly custom-quoted. The go-to-market is sales-led, combining an SEO-optimized parts catalog with direct expert outreach and on-site service deployment targeting power generation operators globally. Greg Young serves as President & CEO.
