CNI's Record Grain Volume Reinforces Base Case but Capex and Regulatory Risks Loom Large

What happened

Canadian National Railway reported moving a record 2.67 million metric tons of Western Canadian grain in February 2026, building on 2025's all-time high volumes as it enhances capacity and winter preparedness. This performance aligns with the company's 2025-26 Grain Plan, a key tailwind noted in the DeepValue report, which supports the base case of disciplined cost control offsetting tariff-hit segments. However, the report emphasizes that CNI's mid-single-digit EPS growth relies heavily on cost cuts and capex normalization, not just volume gains, amid escalating U.S. tariffs and regulatory scrutiny. While the grain record validates operational execution, it does not address critical risks like potential capex increases above C$3.4 billion from safety mandates or sustained tariff pressures on other segments. Consequently, the overall investment narrative remains centered on a narrow risk-reward profile, with the WAIT rating intact pending better entry points or clearer evidence on capex and regulatory outcomes.

Implication

The record grain movement supports CNI's base case scenario of low-single-digit RTM growth and mid-single-digit EPS growth, reinforcing the grain-led volume tailwind already priced in. However, with tariffs continuing to depress autos and intermodal volumes, earnings resilience depends more on cost control and capex discipline than on isolated volume spikes. The guided 2026 capex reduction to C$2.8 billion remains a pivotal thesis element; any upward revision due to regulatory safety requirements would break the capex normalization narrative and compress free cash flow. Management's layoffs and productivity efforts are necessary for margin defense, but investors must monitor service metrics for signs of operational stress from these cuts. Thus, maintaining a watchlist approach is prudent, with consideration for entry only if the stock falls below $90 while capex and operating ratio trends hold firm.

Thesis delta

The record grain volume does not shift the core investment thesis, as it affirms an existing tailwind already embedded in the base case. No change is warranted to the WAIT rating or risk-reward assessment, with capex normalization and regulatory risks remaining the primary drivers of future performance.
