Competitive Rivalry

Regulated utility returns reduce direct price competition, so OGS competes more on allowed rate base growth than on retail pricing, unlike unregulated peers.

Service territories are geographically exclusive, limiting head-to-head rivalry and supporting steadier margins than merchant energy or competitive utility businesses.

Capital intensity and long asset lives discourage aggressive capacity duplication, which keeps industry rivalry structurally lower than in less regulated infrastructure sectors.

Peer pressure still exists through regulatory benchmarking and reliability expectations, but it constrains returns less than market-based competition does for global peers.

Threat Of New Entrants

Franchise-like service territories, regulatory approvals, and incumbent asset ownership create high entry barriers, making new utility entrants far less likely than in deregulated markets.

OGS benefits from sunk infrastructure and permitting complexity that would require years and heavy capital to replicate, preserving incumbent economics versus smaller peers.

Rate regulation lowers the incentive for greenfield entry because returns are capped, so potential entrants face weak economics even before financing and construction risk.

Compared with global energy peers, OGS is structurally insulated from new competition because access to customers is controlled by geography and regulation.

Bargaining Power Of Suppliers

Large equipment, pipe, and construction suppliers can influence project costs, but regulated cost recovery limits the margin impact versus unregulated peers.

Labor and specialized utility contractors remain important inputs, yet OGS can spread procurement across a sizable regulated asset base, reducing supplier leverage.

Fuel and purchased gas exposure can create pass-through timing risk, but commodity costs are generally recoverable, so supplier power is less binding than in merchant businesses.

Compared with global peers, supplier power is moderate because capital projects are unavoidable, though regulation softens the direct hit to profitability.

Bargaining Power Of Buyers

Retail customers have limited switching options inside regulated territories, so buyer power is structurally weaker than in competitive energy markets.

Rate cases and allowed-return frameworks shift pricing authority to regulators, which reduces customer leverage over margins versus unregulated peers.

Industrial and large commercial customers can pressure regulators on affordability, but that influence is indirect and usually slower than direct price negotiation.

Compared with global peers, OGS retains stronger pricing stability because customers cannot easily bypass the utility network or source essential service elsewhere.

Threat Of Substitutes

Distributed generation, electrification, and efficiency measures can reduce long-run gas demand, but adoption is gradual and uneven across OGS’s service areas.

Substitution risk is more relevant over a multi-year horizon than in the near term, so it pressures volume growth more than current pricing power.

Compared with global peers, OGS faces moderate substitution because regulated service obligations and infrastructure dependence slow customer migration away from the network.

Policy-driven decarbonization could accelerate substitution, but the impact on margins remains mediated by regulation and rate-base recovery.

Overall Score

OGS operates in a structurally protected regulated utility model with high entry barriers and limited buyer power, while supplier and substitution pressures remain manageable.
