Frequently asked questions
What is Otter Tail Corporation's revenue?
Otter Tail Corporation's trailing twelve-month revenue is $1.31B. 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 OTTR?
In its most recent fiscal year, OTTR ran a gross margin of 27.81%, an operating margin of 26.51%, and a net margin of 21.16%. 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 OTTR generate?
OTTR produced $97.92M 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 OTTR's balance sheet healthy?
OTTR holds $386.19M in cash and equivalents against $963.57M in long-term debt, on $1.86B of shareholder equity. That debt is best read against the cash flow the business throws off each year.
