Pipeline and storage infrastructure that supports system reliability and gas balancing.

Customers
SoCalGas sells primarily to regulated retail end users in its service territory, including households, businesses, and industrial accounts that rely on natural gas for heating, cooking, process heat, and other energy needs. It also serves core customers through procurement and balancing mechanisms that pass through commodity costs under California regulation. The company’s customer base is anchored in a dense, utility-style network rather than discretionary end-market demand.
Households in Southern California that buy gas for heating, cooking, and water heating through regulated service.
Retail, office, and service businesses that use natural gas for space heating and daily operations.
Manufacturers and other large users that buy gas for process energy and operational fuel needs.
Customers whose commodity gas costs are purchased and recovered through regulated rates.
Strategy
SoCalGas’ operating model centers on regulated cost recovery, system reliability, and continued investment in utility infrastructure that can be reflected in rates over time. Its strategic position depends on maintaining constructive CPUC relationships, managing balancing accounts, and aligning capital spending with authorized recovery mechanisms. The company also uses procurement and GCIM mechanisms to manage core gas purchasing within a regulated framework.
The business depends on timely recovery of commodity, operating, and capital costs through CPUC-approved rates.
Utility capital spending supports reliability and creates future rate base growth when approved for recovery.
Core gas purchases are largely pass-through, but procurement performance affects GCIM sharing and customer outcomes.
Geography
SoCalGas operates mainly in Southern California, with service extending across most of the region and into part of central California. Its business is geographically concentrated in one regulated utility territory, so local weather, population density, and California regulatory decisions are central to performance and operations. The company’s infrastructure and customer obligations are tied to this service area rather than a multi-country footprint.
Risks
SoCalGas is exposed to regulatory risk because earnings and cash flow depend on CPUC-approved rates, balancing accounts, and the timing of cost recovery. It also faces commodity-price, weather, and demand variability in gas procurement and throughput, even though many costs are passed through to customers. Broader utility risks include environmental regulation, litigation, customer payment timing, and the need to fund large capital programs within an approved capital structure.
Revenue and cash flow depend on CPUC decisions, balancing accounts, and authorized rate updates.

Gas procurement costs and customer usage can move sharply with market prices and temperature patterns.
Exposure: Core gas purchases and throughput
Policy shifts can affect utility operations, compliance costs, and long-term gas demand.

Accounting
Judgemental itemsDifferences between costs incurred and amounts billed are deferred and later recovered or refunded, affecting revenue timing.
Impact: Can materially shift quarterly revenue and cash flow
Program costs are recovered in revenue and offset in operating expenses, making gross line items less informative.
Impact: Affects reported revenue and O&M comparability
SoCalGas shares in savings or costs outside benchmark ranges, creating earnings sensitivity to procurement performance.
Impact: Can create modest earnings volatility
Utility accounting depends on future recovery approval for certain costs and timing differences.
Impact: Affects balance sheet size and earnings recognition
