Most Popular Narrative: 10.7% Undervalued

California Water Service Group’s most popular narrative assigns a fair value of $55.50, which is well above the last closing price of $49.58. This highlights analysts’ belief that current shares may not reflect the company’s future growth trajectory and margin outlook.

Accelerating capital investment in water infrastructure and modernization, driven by increasing water scarcity, climate adaptation needs, and urban population growth, positions Cal Water to expand its regulated rate base by a projected ~12% CAGR. This supports sustained long-term revenue and cash flow growth. Expansion into high-growth areas such as Texas and the development of large-scale reuse projects like Silverwood create a pathway for customer base expansion and incremental capital deployment, which is expected to drive future top-line and earnings growth.
