ENBRIDGE INC (ENB) stock intrinsic value fair value estimate & owner earnings analysis

Enbridge is one of North America's largest energy infrastructure companies. It reports in Canadian dollars, and every figure here is in Canadian dollars. It has four businesses. Liquids Pipelines, led by the Mainline system, carries Western Canadian crude to refiners in the US Midwest and Gulf Coast. Gas Transmission includes the Texas Eastern system and T-North. Gas Distribution and Storage runs its Canadian gas utility plus the East Ohio, Questar and PSNC (North Carolina) utilities bought in 2024. Renewable Power Generation is the fourth. Most earnings come from tolls set by negotiated settlements or regulators, and from long-term contracts, so commodity prices matter less here than at a producer. In 2025, revenue was $23.1 billion from Canada and $42.1 billion from the United States. How we measured earnings. We started from audited operating cash flow and stripped out working-capital swings. We subtracted stock compensation. We also subtracted the share of capital spending needed just to keep existing assets running; the remainder we treated as growth spending. The result is owner earnings per diluted share: $3.54 in 2022, $3.44 in 2023, $3.32 in 2024 and $2.75 in 2025. These figures are after interest. Enbridge carries a lot of debt, so we valued the business before its lenders and then subtracted what it owes. Before interest, the business produced about $4.98, $5.08, $5.24 and $5.00 per share in 2022 through 2025. We anchored on the median of those four years, about $5.04 per share. Earlier years are left out. They come before the US Line 3 Replacement entered service in 2021, and they include years reshaped by earlier mergers and restructurings. They describe a smaller business. Our previous figures used a different calculation and are not comparable to these. Recent trend. On this before-interest measure, per-share cash flow fell about 4.5% in 2025. Capital spending needed to sustain the enlarged business, including a first full year of the newly bought utilities, rose faster than operating cash flow, and the share count rose 1.3%. First-half 2026 operating cash flow before working capital was flat with the first half of 2025. So the base case starts with the same 4.5% decline in year one and assumes no rebound. Base case. After year one, cash flow grows 2% a year through year five and 1.5% a year through year ten, then holds flat. We counted only growth that is already secured: projects the company lists as commercially secured, and the Mainline tolling settlement through the end of 2028. Examples are Mainline Optimization Phase 1 (US$1.4 billion, 2027), Southern Illinois Connector (2028), T-North Expansion and the Texas Eastern modernization. We also counted the Mainline investment of up to US$1.3 billion through 2028, which earns a return under that settlement. We did not count rate-base growth beyond what is already approved, new projects not yet sanctioned, or renewal of the tolling settlement on better terms. Beyond year ten we assume no growth. Pipelines and gas utilities are long-lived and keep getting re-rated, but we have no evidence for growth that far out. On this path the business is worth about $90.43 per share, roughly $198 billion. Lenders and senior holders have claims of about $113.7 billion: $112.1 billion of borrowings less $2.0 billion of cash, $6.8 billion of preference shares that rank ahead of common, and $3.5 billion of outside interests in partly owned subsidiaries. That figure includes a credit of about $6.7 billion because Enbridge's debt costs well under 6%. Cash interest paid was $4.9 billion in 2025 on roughly $103 billion of average debt. Claims come to about $51.93 per share, leaving about $38.50 per common share. Bear case. The 10th-percentile path combines three risks. The first is Line 5. In the Bad River Band case, a 2023 federal court order requires Enbridge to stop operating Line 5 on reservation parcels without a valid right-of-way by June 16, 2026. Enbridge appealed and asked for a stay; the appeal was pending when the latest annual report was filed. Michigan's Attorney General is separately trying to cancel the 1953 Straits of Mackinac easement. The second is the end of the Mainline tolling settlement in 2028, which could be renewed on worse terms. The third is a downturn of the kind the industry saw in the 2015-16 oil collapse and the 2020 shutdown, which would hit volumes, the gas utilities and refinancing at the same time. In this case cash flow falls 4.5%, 8.5%, 6.5% and 5% over the first four years, to about $3.91 per share. That is a cut of about 22% from the anchor, though still above the $3.09 to $3.61 the business produced in 2018-2021, before Line 3 and the US utilities. It stays flat through year ten and then declines 2% a year. We gave no credit for cheap debt here, on the assumption that maturities get refinanced at market rates during the downturn. The business would be worth about $57.02 per share ($124.9 billion) against claims of $120.4 billion ($54.99 per share). That leaves about $2.03 per share: in this case, almost everything the business is worth belongs to lenders and preferred holders. Even here, cash flow before interest of about $8.6 billion a year still covers the $4.9 billion interest bill, so the case can carry its debt. Bull case. Secured projects come in on schedule, and the newly bought US utilities earn their allowed returns. Cash flow rises 1% in year one, then 3% a year through year ten, and 1% a year after that. The business would be worth about $117.29 per share ($256.9 billion), leaving about $65.36 per share after the same $113.7 billion of claims. Margin of safety. How sure are we of the earnings level? Moderately. The before-interest stream has held between $4.98 and $5.24 per share for four years. But it is a recent level, and it depends on debt costs and on capital spending that we split into maintenance and growth ourselves. The worst plausible outcome is a forced shutdown of Line 5 together with a weak Mainline renewal during a downturn. The assets are hard, regulated and very hard to replace, so the business would survive. But debt of about $112 billion means common shareholders absorb nearly all of the loss, as the bear case shows. The things we are most likely to be wrong about are growth and maintenance spending. If cash flow simply stays flat at the anchor instead of following the base path, the shares are worth about $32.09. Enbridge pays a large dividend: $8.2 billion in 2025, about $3.77 per share. That is more than the $2.75 of owner earnings per share, so part of the dividend is effectively funded with borrowing and should not be counted on to keep growing. The price assumes about a five-year holding period. At $18 per share, the base case implies about 25% a year over five years, counting what the business earns for owners along the way. The flat-earnings case implies about 21%. By $19 the flat case is down to about 20%, and the bear case gives little protection at any price because so much of the value goes to debt. So the margin-of-safety price is $18.
