Southwest Gas’s (SWX) Pipeline Bet Just Got $600M Bigger
Southwest Gas Holdings (SWX) reported Q2 net income of $42.1M, reversing a $40.2M loss from 2025. The Great Basin 2028 Expansion Project's cost estimate rose to $2.3B from $1.7B due to higher demand. Management expects annual margins of $270M-$300M once the project is operational. Regulatory approvals added incremental revenue and deferred income. However, core natural gas distribution earnings declined, and expenses increased.
