Enbridge Inc. -- How the Business Works
Enbridge is the largest pipeline operator in North America and the largest natural gas utility
by volume (~9.3 Bcf/d delivered to ~7M customers). The Enbridge Mainline system carries ~66%
of all Canadian crude oil exported by pipeline (~3.1 MMb/d), operating at ~97% utilization with
no viable alternative -- effectively a regulated natural monopoly. Approximately 98% of cash
flows are contracted or regulated, providing utility-like stability. FY2025 adjusted EBITDA
reached ~C$20B, up ~7% YoY, driven by the full-year contribution of the Dominion gas utility
acquisitions (East Ohio Gas, Questar, PSNC). The company sits at the intersection of multiple
secular themes: Canadian energy security, North American LNG export growth, AI data center
power demand, and gas utility rate base compounding. The stock trades at 24.9x forward P/E
near 52-week highs ($54.15 vs $55.44 high), with a 5.1% dividend yield and 29 consecutive
years of dividend increases. Enbridge is a steady compounder -- not an explosive grower --
targeting ~5% EBITDA CAGR through regulated expansion and brownfield projects.

Near-monopoly in Canadian crude exports -- no viable alternative exists:
The Enbridge Mainline shipped ~3.1 MMb/d in 2025, representing ~66% of all Canadian crude
exported by pipeline out of total WCSB pipeline exports of ~4.7 MMb/d. The system operated
in apportionment for all but 3 of the last 12 months, with double-digit apportionment in
Jan/Feb 2026. Trans Mountain (TMX) at 890 kb/d serves the Pacific Coast (different end market).
Keystone (TC Energy) at ~590 kb/d goes to PADD II/Cushing. No new greenfield pipelines are
under construction or realistically approvable in the current Canadian regulatory environment.
All expansion capacity (MLO1-4) is brownfield, in-corridor, and under Enbridge control --
virtually impossible for a competitor to replicate. This is effectively a regulated natural
monopoly with 10+ year structural barriers to entry.

Key Growth Themes and Enbridge Positioning
Canadian Energy Security
Dominant
WCSB +1M b/d growth thru 2035
Enbridge IS this theme
NA Gas / LNG Exports
Strong
Gas Tx EBITDA +27% in 2 yrs
$10-20B unsanctioned projects at FID
AI Data Center Demand
Emerging
50+ gas supply opportunities
1+ GW solar deals with MAG 7
Gas Utility Rate Base
Strong
~10% rate base growth (up from 8%)
~$3B/yr foundational utility capex
Growth pipeline is large but inherently regulated: Enbridge has $10B to $20B
of unsanctioned growth projects expected to reach FID in the next 24 months, with Gas
Transmission having the largest opportunity set. The Mainline expansion program (MLO1 at
+150 kb/d for $1.4B targeting 2027 in-service, MLO2 at +250 kb/d ~2028, MLO3/4 under study)
provides the only credible incremental egress for growing WCSB production. Spare pipeline
egress capacity is projected to shrink to ~100 kb/d by end of 2025 and become fully utilized
by late 2026. On the gas side, Bay Runner extension (supplying Rio Grande LNG), Eiger Express
upsized from 2.5 to 3.7 Bcf/d, and 50+ potential data center gas supply opportunities are
under development. However, the regulated/contracted model inherently caps growth at ~5%
EBITDA CAGR -- Enbridge captures these themes through steady compounding, not explosive upside.

Risks and catalysts -- what to monitor
Catalysts
Mainline expansion sanctioning -- MLO1 (+150 kb/d, $1.4B, 2027) is proceeding; MLO2 (+250 kb/d, ~2028) and MLO3/4 under study. WCSB production growth of 1+ MMb/d through 2035 ensures demand. Spare egress shrinking to zero by late 2026
Gas Transmission mega-cycle -- $10-20B of unsanctioned projects approaching FID; Texas Eastern at record 15+ Bcf/d; LNG export capacity buildout drives incremental throughput; Bay Runner and Eiger Express advancing
AI data center power demand -- 50+ gas supply opportunities requiring up to 10 Bcf/d; dual exposure via gas transmission AND renewable power; 1+ GW solar deals signed with MAG 7 companies
Utility rate base compounding -- rate base growth now ~10% (up from 8% at Dominion acquisition); ~$3B/yr foundational capital; supportive regulatory outcomes in Utah and North Carolina
Dividend compounding -- 29 consecutive years of increases; 5.1% yield at current price; 3-5% annual dividend growth expected; attractive in a falling rate environment
Key Risks
Canadian trade/tariff dynamics -- U.S.-Canada trade tensions could theoretically impact cross-border pipeline economics, though management views this as manageable given the essential nature of the infrastructure
Regulatory risk -- toll structures, rate cases (new Ohio filing pending), and environmental regulations create ongoing uncertainty; CTS toll mechanism constrains upside in exchange for volume stability
Growth inherently capped -- regulated/contracted model limits EBITDA CAGR to ~5%; the stock is a compounder, not an explosive grower; investors seeking high growth will be disappointed
Energy transition long-tail risk -- secular decline in crude oil demand beyond 2035-2040 could impair Liquids Pipelines (46% of EBITDA); timeline is long but existential for the core asset
Valuation near highs -- stock at $54.15 vs 52-week high of $55.44; 24.9x forward P/E is not cheap for a ~5% EBITDA grower; limited margin of safety at current levels; most of the re-rating may already be priced in
