Business Overview: Garrett Motion Inc. (NASDAQ: GTX)

---

Executive Summary

Garrett Motion Inc. is a 70-year-old technology company specializing in turbocharging, air and fluid compression, and high-speed electric motor technologies, serving automotive and industrial OEMs as well as an independent aftermarket. Spun off from Honeywell in 2018, Garrett supplies more than 60 OEM customers across light-vehicle gasoline and diesel, hybrid, commercial vehicle, and industrial applications, while pursuing electrification adjacencies — E-Turbo, E-Compressor, fuel cell compressors, and pre-development E-Powertrain/E-Cooling technology — designed to extend its turbocharging expertise into a lower-emission future.

Fiscal 2025 delivered steady, modest growth (net sales up 3% to $3,584 million) alongside real margin and earnings improvement (net income of $310 million, up from $282 million; Adjusted EBITDA margin of 17.7%, up from prior year), while the company returned substantial capital to shareholders through $208 million of buybacks that reduced share count by 8% year-over-year — evidence of a mature, cash-generative business even as its core internal-combustion-engine turbocharger market faces long-term secular pressure from vehicle electrification.

1. Core Business Model & How They Work

Garrett designs and manufactures turbocharger and compression technology that OEMs integrate into vehicle and industrial engines, supplemented by a global aftermarket replacement parts business.

[ R&D (1,330 Engineers, 6 Centers) + 1,350 Patents ] ➡️ [ Turbocharger/Compressor Manufacturing (7 Low-Cost-Country Facilities) ] ➡️ [ OEM Design Wins (60+ Customers, ~86% of Revenue) ] + [ Aftermarket (370+ Distributors, 165 Countries, ~14% of Revenue) ] ➡️ [ Installed Base of ~150 Million Vehicles ➡️ Recurring Aftermarket Replacement Demand ]

Key Operational Drivers

1. OEM-Centric, Design-Win Business Model: About 86% of 2025 revenue came from OEM sales under open purchase orders with no minimum purchase commitments — Garrett must continually win new vehicle-program design slots rather than relying on guaranteed volumes, with top ten customers representing 62% of net sales (Stellantis 12%, BMW 11%, Ford 11% in 2025).
2. Technology Leadership in Variable Geometry Turbos: VNT (variable geometry turbocharger) technology represented about 21% of global gasoline turbo production in 2025, forecast to reach 29% by 2030 — a higher-value product category where Garrett's engineering differentiation matters most.
3. Electrification Hedge: E-Turbo, E-Compressor, fuel cell compressors, and pre-development E-Powertrain/E-Cooling technology (about 50% of 2025 RD&E spend targeted zero-emission technologies) represent Garrett's strategic bet that its core compression/high-speed-motor expertise transfers to an electrified and hydrogen future, even as traditional ICE turbo volumes eventually decline.
4. High-Margin, Diversified Aftermarket: A 150-million-vehicle installed base supports a 370+-distributor, 165-country aftermarket network generating recurring, less OEM-cycle-dependent replacement-parts revenue, though this segment declined 5% in 2025.
5. Low-Cost Manufacturing Footprint: More than 89% of products are made in low-cost countries (China, India, Mexico, Brazil, Romania, Slovakia) across seven facilities — a structural cost advantage supporting competitive OEM pricing.

Garrett's Item 1 disclosure emphasizes competitive strengths (technology leadership, OEM relationships, low-cost manufacturing) rather than naming competitors directly, with competitor detail reserved for risk-factor disclosure; the turbocharger industry's well-known major competitors include BorgWarner, IHI Corporation, and Mitsubishi Heavy Industries, all of which compete for the same OEM design-win opportunities across gasoline, diesel, and hybrid applications.

5. Strategic Strengths & Risks

Strengths (The Moat)

• Deep OEM relationships and technology leadership: 1,350 patents and patents pending, 1,330 engineers, and relationships with 60+ OEMs including top customers Stellantis, BMW, and Ford reflect decades of accumulated turbocharging engineering expertise.
• Large, high-margin installed base: Nearly 150 million vehicles in the installed base support a recurring aftermarket replacement business through 370+ distributors in 165 countries.
• Low-cost global manufacturing: More than 89% of production in low-cost countries supports competitive OEM pricing while preserving margin.
• Credible electrification bridge strategy: Meaningful RD&E investment (about 50% of spend) into E-Turbo, E-Compressor, and fuel cell compressor technology gives Garrett a plausible path to remain relevant as powertrains electrify, rather than facing a cliff-edge obsolescence risk.

Risks

• No guaranteed volume commitments: OEM supply is through open purchase orders with no minimum purchase commitments — Garrett must continually win new design slots, and a lost program can disappear with little warning.
• High customer concentration: Top ten customers represent 62% of net sales, with Stellantis, BMW, and Ford alone at 12%, 11%, and 11% respectively — meaningful dependence on a small number of OEM relationships.
• Long-term secular EV transition risk: As battery electric vehicle penetration grows (19% average BEV penetration assumed in 2026 guidance), the total addressable market for traditional ICE turbochargers faces an eventual structural decline that electrification-adjacent products must offset.
• Aftermarket softness: The aftermarket category declined 5% in 2025 (-6% at constant currency), a headwind in what is otherwise Garrett's highest-margin, most recurring revenue stream.

7. Summary Conclusion

Garrett Motion has built a durable, technology-differentiated position in turbocharging — anchored by deep OEM relationships, a large patent portfolio, and a substantial recurring aftermarket business — while delivering real earnings growth and aggressive capital returns in fiscal 2025. The company's electrification strategy (E-Turbo, E-Compressor, fuel cell compressors) represents a credible, R&D-backed attempt to extend its core compression and high-speed-motor expertise beyond the internal combustion engine, but the central long-term question remains whether these adjacent technologies can scale fast enough to offset the eventual structural decline in traditional ICE turbocharger demand as battery electric vehicle penetration continues to rise.
