Sempra does not benefit meaningfully from network effects in the way software platforms or payment systems do. A household using SoCalGas, SDG&E, or Oncor does not make the service more valuable for other users; the value comes from regulated delivery infrastructure, not from a growing user ecosystem. There are some indirect scale benefits from serving a dense customer base, gathering operating data, and coordinating gas and power assets across a larger footprint, but these are not true network effects. Multi-homing is irrelevant for most end users because local utility service is a geographic monopoly, not because the network becomes more valuable as it expands. That leaves this pillar as a weak contributor to overall moat strength.

Switching costs are high because most of Sempra's core customers cannot practically switch away from the local wires or gas system. A residential or commercial customer in Southern California or Oncor's Texas footprint cannot easily choose another distribution network, and new physical infrastructure would be prohibitively expensive and time-consuming to build. While customers can reduce usage, self-generate, or choose competitive power suppliers in certain markets, the underlying connection to utility delivery remains sticky. Industrial users also face operational disruption if they relocate or restructure energy supply. The result is not software-like lock-in, but a durable captive relationship created by geography, regulation, and embedded assets. This is a major moat pillar.

Sempra's intangible assets are less about brand and more about regulated franchise rights, permits, rights-of-way, environmental approvals, and technical operating expertise. Those assets are difficult to replicate quickly because they depend on long approval cycles, community trust, and regulatory relationships. The company's ability to develop large-scale LNG, transmission, and gas infrastructure also reflects accumulated know-how in project management and compliance. However, these assets are not invulnerable: regulatory scrutiny, public opposition, and political pressure can slow new investments or raise costs, especially in California. The brand itself is not a powerful consumer differentiator. Even so, the combination of licenses, approvals, and operating reputation provides a meaningful barrier to entry and supports long-lived franchise value.

Sempra enjoys meaningful cost advantages from scale, density, and access to regulated capital recovery. Large service territories let it spread fixed system and overhead costs across millions of customers, lowering unit economics relative to smaller peers. In addition, utilities with stable regulatory frameworks often finance large infrastructure programs at attractive rates because cash flows are predictable, which can reduce the effective cost of capital. Sempra's footprint in Southern California and Texas also provides operating density that improves maintenance, reliability, and customer-service efficiency. These advantages are real, but not unassailable: similar benefits exist for other large regulated utilities, and project execution mistakes can erode returns. Overall, the cost edge is strong enough to support a durable moat.

Efficient scale is Sempra's strongest moat pillar. Electric and gas distribution networks are classic natural monopolies: building a second set of poles, wires, pipelines, substations, and service connections in the same territory would destroy economics rather than create value. Regulation reinforces that structure by limiting entry and franchise competition, so incumbents like SoCalGas, SDG&E, and Oncor operate in markets where new rivals face extreme economic and regulatory barriers. Customers need continuous, reliable service, which favors one dominant network rather than multiple redundant systems. While some adjacent businesses, such as LNG infrastructure, are more competitive, the core utility platform operates in highly efficient scale environments. That confers long-duration pricing and cash-flow durability.
