USA Income taxes and NOLs of a public company

[sigma]

Hi to all, I am new here and I would like to ask a question about income taxes and NOLs of a public company ticker: TPNL.

The company is profitable but they still have a valuation allowance that is equal to their entire NOLs amount, how they can do that and why?

And why their "change in valuation allowance" is positive and their "change in carryovers and tax attributes" is negative?

thanks in advance for any help I will receive.
