For many Heavy Equipment OEMs, understanding parts market share capture is becoming a more important priority – particularly in areas such as front counter, wholesale, and collision-related sales. This session will explore how OEMs are measuring penetration in these channels, what data they are using, and how those insights inform parts planning and aftermarket strategy. The discussion will focus on practical questions: how companies define and estimate market opportunity, how they track share capture, where visibility is strongest or weakest, and how this information is used to guide commercial and supply chain decisions. Ducker Carlisle will bring in perspective on the competitive landscape, including how aftermarket suppliers are approaching these segments, and how HE OEMs can capture this information in the future. This topic is expected to be especially relevant for Heavy Equipment participants, though Automotive OEMs are welcome to participate and share their perspective.
