Executive Summary

South Bow's Q1 2026 results show slight year-over-year revenue and earnings declines, with revenue of $491M (down 1.4%), net income of $77M (down 12.5%), and normalized EBITDA of $257M (down 3.4%). The Keystone Pipeline segment performed well (revenue +10%), but Marketing segment revenue fell 40% and swung to a loss. Additionally, the company disclosed a material weakness in internal controls over financial reporting due to a new ERP system implementation. Guidance for 2026 was reaffirmed, and the quarterly dividend remains unchanged at $0.50/share.

  • Operating cost pressures from MP-171 incident and ongoing pipeline integrity work
  • Net debt-to-EBITDA ratio of 4.7x limits financial flexibility
