CPKC Reports Record Grain Volumes, But Pricing Concerns Remain

What happened

CPKC announced record September and third-quarter grain shipments across Canada and the U.S., reflecting strong execution in the bulk segment. This follows Q2 2025 results where revenue growth was driven by higher volumes (RTMs) but partly offset by lower freight revenue per RTM. The grain records add to evidence that the network is handling increased volumes, particularly after the twinning of the Laredo bridge. However, grain is a lower-margin commodity, and the announcement does not provide details on pricing or the impact on overall revenue mix. Investors should monitor whether this volume strength translates into improved pricing and operating ratio, or if it merely reflects seasonal demand.

Implication

The record grain shipments support the volume-driven growth narrative, but we caution that grain is typically lower margin than intermodal or merchandise. Without evidence of better pricing or mix, the improvement in operating ratio may be limited. The stock already trades at a premium (~23x P/E), so additional upside may require resolution of the revenue per RTM pressure. We maintain our BUY stance, but the grain news does not by itself change our thesis; we continue to watch pricing and core adjusted combined OR. If revenue per RTM stabilizes or improves with rising volumes, that would strengthen the case; otherwise, persistent pressure could lead to a downgrade to HOLD.

Thesis delta

The record grain volumes are a positive confirmation of the network's ability to handle increased bulk volumes, but they do not address the pricing/mix concern flagged in our prior report. Our BUY stance remains based on cross-border growth and efficiency gains, with the key watch item being whether volume growth translates into margin improvement. No change to the overall investment thesis at this time.
