Frequently asked questions
What is California Water Service Group's revenue?
California Water Service Group's trailing twelve-month revenue is $1.01B. Revenue is the top line the whole model builds on, and at this scale the question shifts from how fast it grows to whether margins hold as it compounds.
How profitable is CWT?
In its most recent fiscal year, CWT ran a gross margin of 36.74%, an operating margin of 18.16%, and a net margin of 12.82%. Margins this high mean most of each extra dollar of revenue drops through to profit, which is the signature of real pricing power.
How much free cash flow does CWT generate?
CWT produced $-214.43M in free cash flow in its most recent fiscal year. Free cash flow is what is left after running and reinvesting in the business, and it is the cash that actually funds buybacks, dividends, and a stronger balance sheet.
Is CWT's balance sheet healthy?
CWT holds $51.82M in cash and equivalents against $1.47B in long-term debt, on $1.69B of shareholder equity. That debt is best read against the cash flow the business throws off each year.
