That "profit" included a one time grant from the gov for something like $120,000, I forget the exact amount.
Q1 2021 with sales of $600,000 and cost of goods sold at ~50% with a net loss of ~$140K. Do the math and a reasonable estimate for profits comes to 700-750K.
But using last quarters numbers, 360K sales, 20% cogs, loss 17K, you might be right. So let's say $500,000 for a good quarter?
I'm suspicious that they can keep their costs as low as last quarter, we'll see.
