Most Popular Narrative: 6% Overvalued

Despite Hydro One’s fair value estimate of CA$50.21, shares recently closed higher at CA$53.37. The favored narrative suggests the stock is priced above what future earnings and regulated returns might justify, which is an important distinction for value-focused investors.

“Surging electricity demand in Ontario, projected to grow 70% by 2050, along with government policy accelerating transmission and distribution infrastructure expansion, position Hydro One for sustained, rate base-driven revenue and earnings growth as electrification of transportation and industry advances. The provincial Integrated Energy Plan explicitly prioritizes new transmission and grid modernization projects for Hydro One, enhancing multi-year capital investment visibility and supporting higher regulated asset base, which should boost future allowed revenues and long-term EPS growth.”
