KEY MARKET OPPORTUNITY

Expansion of Digital Distribution Channels and Strategic Aftermarket Partnerships Creating Significant Market Opportunity

• Parts manufacturers and distributors are broadening digital ordering platforms, part-number lookup tools, and business-to-business marketplaces that connect independent workshops directly with suppliers, reducing dependence on traditional multi-tier wholesale distribution. This shift is creating opportunities for suppliers to capture higher margins by selling closer to the end repair shop while improving parts availability and delivery speed.
• Cross-industry partnerships between component manufacturers and regional distributors are opening new categories such as agricultural, off-highway, and specialty vehicle aftermarket segments that were traditionally served by fragmented local suppliers. These partnerships allow global suppliers to extend OE-quality product ranges into adjacent aftermarket categories without building entirely new distribution infrastructure from the ground up.
• The growing complexity of electrified and connected vehicles is opening opportunities for value-added services such as remote diagnostics subscriptions, battery health monitoring, and workshop management software, allowing suppliers to generate recurring revenue beyond one-time parts sales. Suppliers that combine hardware, software, and training into bundled offerings are positioned to capture a larger share of the total service transaction.
• Continental's ContiTech group sector signed a strategic partnership with GRANIT PARTS, a division of the FRICKE group, at Agritechnica 2025 to expand its OE-quality rubber and polyurethane component range into the agricultural aftermarket through GRANIT PARTS' distribution network.
