Yes, this is a wafer-thin margin but consider that some Payments to suppliers will relate to the cost of acquisitions, $909k for Transaction costs in the FY22 P&L which can be considered non-recurring. Suppliers in this case would be accountants, lawyers, and other professionals otherwise it would be in the investing section of the cash flow.
Ongoing profit margins after tax, after adding this back ($636k after tax) give roughly $1.5M positive c/f ~ 1.5% net margin.
At this margin, for next year, on say $120M revenue, gives $1.8M NPAT which looks good at current MC or EV.
And $120M revenue is just run-rate including the existing acquisitions and a little organic growth. It doesn't need further acquisitions.

I wouldn't apply a large multiple for this stock since a lot can go wrong on such tight margins. Also debt has gone up a lot so a cap raise is likely, especially if they continue to acquire. And growth needs working capital. It's going to take a long time to pay down the debt at $1.5M p.a.
