AT1 FY21 - General Discussion + FA, page-127

What is it that seperates Atomo from the rest of the feild though?
The moat for this business is what concerns me. US approval seems a headache in multiple sectors from many businesses with excess time delays being experienced. For example Aeris is a covid killing cleaning agent that started the 4-8 week approval process from EPA in US in May and yet to be certified despite health and Covid conditions, US experiencing astronomical positive covid cases and many school and work places returning. my concern as stated is this companies moat and realistic potential to secure contracts before a better named company swoops on major deals...
Hoping to learn more about AT1 and its future from what I see as having potential but also some real barriers. Please feel free tk entlighten me
