Frequently asked questions
What is Tiziana Life Sciences Ltd's revenue?
Tiziana Life Sciences Ltd's trailing twelve-month revenue is $-3.60M. 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 much free cash flow does TLSA generate?
TLSA produced $-12.87M 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 TLSA's balance sheet healthy?
TLSA holds $4.01M in cash and equivalents against — in long-term debt, on $52000.00 of shareholder equity. That debt is best read against the cash flow the business throws off each year.
