Frequently asked questions
What is Sixth Street Specialty Lending Inc's revenue?
Sixth Street Specialty Lending Inc's trailing twelve-month revenue is $426.10M. 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 TSLX?
In its most recent fiscal year, TSLX ran a gross margin of 72.84%, an operating margin of 53.55%, and a net margin of 47.34%. 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 TSLX generate?
TSLX produced $180.28M 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 TSLX's balance sheet healthy?
TSLX holds $2.94M in cash and equivalents against — in long-term debt, on $1.61B of shareholder equity. That debt is best read against the cash flow the business throws off each year.
