Why Bernstein says there is still room to run in this defensive growth sector

The cleanest read-through is that this is less a pure “utilities rerating” story than a capital-allocation story where regulated asset bases become a quasi-bond proxy with embedded growth. If network capex is the dominant incremental driver, the winners are the names with the most visible transmission/distribution backlog and the lowest political friction on allowed returns; the losers are the higher-beta generation-heavy utilities where the market can’t underwrite returns on new spend as cleanly. That also argues for an internal rotation from merchant-exposed power utilities into regulated networks and water, because the latter monetize decarbonization without taking much fuel-price or spark-spread risk.

The second-order effect is that conflict-driven energy security urgency should compress permitting timelines and improve regulator willingness to front-load allowed returns, but that benefit is likely to show up over quarters, not days. In the near term, the market may be underpricing the duration mismatch: capex-heavy utilities can look attractive on EPS growth while still being vulnerable if rates stay elevated, because the implied equity value depends on WACC staying contained. That makes balance-sheet quality and inflation linkage more important than headline dividend yield; the highest-quality compounders should keep winning while leveraged “yield” stories can lag if bond yields reprice.

For NGG specifically, the opportunity is not a short-term geopolitical pop but a 6-18 month multiple grind higher if investors conclude UK network regulation will remain constructive and capex earn-backs are defendable. The contrarian risk is that the current premium is already discounting a lot of policy support; if political rhetoric on affordability intensifies or real rates rise another 50-75 bps, the sector can de-rate even with decent earnings growth. In that scenario, the market will likely punish the most interest-rate-sensitive names first, so the trade should be built around quality and optionality rather than blanket beta.
