Propagation has completed a lap, so the next leg depends on individual results more than chain direction. Among connected nodes the furthest ahead is ExxonMobil (+35.2%) and the furthest behind is Lilly (Eli) (+7.5%). If chain logic explains the gap, the laggard is the next propagation candidate; if not, the link itself deserves a second look. It purchases elastomer inputs and packaging components from Daikyo and holds a 49% interest in Daikyo.
