ASIC v ISX Hearing, page-1308

But just in case you wanted actual reasons, rather than me pointing out that you were Sea Lioning, here you go:

1. The original notice: https://announcements.asx.com.au/asxpdf/20191002/pdf/44945q9b3s6t63.pdf
2. The follow up from ISX that admits in the very first paragraph why they've been suspended ("ISX has been in discussions with ASX and ASIX and can confirm to shareholders that the Company was suspended from trading on 2 October 2019 due to share price volatility") and welcomes the suspension ("The Company welcomes a period of suspension to give it time to clear up rumour and innuendo."): https://announcements.asx.com.au/asxpdf/20191007/pdf/4498grvm46vg81.pdf

What a pity that the company didn't do as promised ("work co-operatively with regulators in coming weeks")?
