BofA cuts Canadian National Railway stock price target on coal weakness

BofA cut Canadian National Railway's price target to $143 from $146 but retained its Buy rating as Q3-to-date revenue ton miles rose 4.6% year over year, ahead of its 2.8% forecast, while carloads declined only 0.4% versus an expected 3.1% drop. Grain (+15.7%) and autos (+23%) were the strongest segments, supported by a strong Western Canadian harvest and increased non-tariffed European and Asian vehicle imports. Growth is expected to moderate in Q4 and 2027 as grain comparisons toughen, while CNI's recently reported Q2 results beat expectations and prompted higher full-year volume and earnings guidance.

Analysis

CNI’s near-term setup is better characterized as an earnings-quality test than a volume-growth story. Revenue-ton-mile outperformance with softer carloads implies mix and length-of-haul are doing disproportionate work; that supports operating leverage while pricing holds, but makes the upside vulnerable if higher-value auto/import lanes normalize. The key read-through is that Canadian rail demand is bifurcating rather than broadly accelerating, limiting the probability of a sustained sector-wide multiple re-rating.

The stronger competitive implication is for CNI versus CP (CP) and, indirectly, UNP: diversified west-coast and Halifax import flows can favor CNI’s network while cross-border auto sourcing remains elevated. However, the harvest-related benefit has a clear rollover risk over the next two reporting quarters, and rail equities typically de-rate before the volume comparison becomes visible in reported results. A weaker North American industrial cycle would compound that risk through Metals & Minerals, coal, and intermodal—segments where pricing cannot fully offset lower asset utilization.

Consensus may be underestimating the importance of operating-ratio execution after the easy volume comparisons fade. If management preserves margin and reiterates earnings growth despite decelerating grain, CNI can defend its premium; if it needs additional productivity measures merely to maintain guidance, investors should interpret that as evidence that current valuation already discounts the favorable mix. The relevant 1-3 month catalysts are weekly rail data, crop export pace, auto import volumes, and fourth-quarter guidance language; the 6-18 month upside depends on whether new U.S./Mexico commercial arrangements create incremental, high-margin traffic rather than simply rerouting existing freight.

Key Decisions for Investors

• Do not add outright CNI/CNR exposure into strength ahead of the next guidance update; maintain only a tactical hold while monitoring whether revenue-ton-mile growth remains ahead of carload growth. A guidance reiteration with decelerating grain would be a warning that mix is masking underlying volume softness.
• Prefer a 3-6 month relative-value position: long CNI/CNR versus short CP, sized market-neutral, only if import-auto and western export data continue to outperform. Thesis target is modest relative outperformance from network mix; exit if auto import volumes roll over materially or CNI’s operating-ratio outlook deteriorates.
• For broad U.S. rail exposure, avoid extrapolating CNI’s traffic mix to UNP. Use UNP as the cleaner domestic industrial-cycle proxy; a sustained deterioration in weekly U.S. carloads would favor underweighting UNP before it necessarily invalidates CNI’s Canada-specific import/export support.
• Set an alert around the next annual volume outlook: a crop forecast below normal combined with weaker intermodal would make CNI vulnerable to multiple compression. Conversely, evidence of durable cross-border Mexico traffic with incremental revenue—not diverted traffic—would falsify the cautious valuation view and justify upgrading to an outright long.
