CNI Sees Mexico Upside via Union Pacific Deal, But Capex Discipline Remains Key

What happened

Canadian National Railway CEO Tracy Robinson highlighted growth opportunities in Mexico through a new agreement with Union Pacific, alongside energy, agriculture, and select domestic markets, while asserting that prior infrastructure investments will support volume gains without a major increase in capital spending. The announcement comes against a backdrop of tariff-driven volume headwinds and a strategic pivot toward cost discipline, with 2026 capex guided down to C$2.8 billion from roughly C$3.35 billion in 2025. The deep value report had assigned a WAIT rating with conviction 3.5, noting that the stock at ~$99 traded at 19x earnings and 12x EV/EBITDA, leaving little margin of safety. Management's commentary suggests an effort to find growth without sacrificing free cash flow, but the specifics of the Union Pacific deal—duration, volumes, revenue sharing—remain undisclosed. If the Mexico corridor materializes as a meaningful new lane, it could offset some tariff losses, but execution risk and potential future capex needs temper the near-term optimism.

Implication

For investors, the Union Pacific deal could unlock incremental cross-border freight, but CN already has a strong network and the incremental benefit may be limited without additional investment. The emphasis on no major capex increase is consistent with prior commentary, yet if the Mexico expansion eventually requires network upgrades or equipment, it could pressure free cash flow and contradict the capex normalization thesis. Energy and agriculture are already core strengths, so the commentary may largely reiterate existing tailwinds rather than introduce new ones. At current valuations, the stock still offers a narrow risk-reward, and waiting for a pullback toward $88 or clear evidence of accelerated RTM growth remains prudent. Regulatory risks, including potential safety mandates, also cloud the outlook, so any position should be sized conservatively until more details emerge.

Thesis delta

The prior WAIT thesis argued that CN's cost cuts and capex normalization supported EPS growth but left little upside at current prices. This news adds a potential growth catalyst via Mexico and energy, but without details on deal economics or volume commitments, it does not materially shift the risk-reward. The thesis remains intact; we would only become more constructive if the Mexico partnership translates into tangible volume increases without future capex creep or if the stock falls below our $88 entry threshold.
