The announcement on 24/4 said that a Board Meeting had been held to approve the contract the previous Friday (that is, on 20/4). In the past, even when CDC was acquired, Board Meetings were typically monthly affairs.

The words referencing this in the announcement were:
----
"A formal contract was approved and executed by the AHF board following its board meeting late on Friday afternoon 20 April 2018 (emphasis added)."

Now to the quarterly CF report. Typically, this also would have been approved at the regular, monthly Board Meeting (as had occurred in the past). Nothing unusual there except that this time round, a Board Meeting for the month has already been held (20/4). It would therefore be quite unusual for a second board meeting to be held (ie: 26/4 - 30/4) in order to then approve the quarterly CF report. So, given that the quarterly was likely approved for release at the Board Meeting on 20/4 (as it is a required release document and there are continuous disclosure rules to comply with), why then hasn't it yet been released?

If the news was good, then likely they would have gone with the old "one, two" announcement routine, to reinforce, ground and extend upon from the first announcement. Yet, now, the question beckons - will the announcement be released anytime before after market close on 30/4? After all, under continuous disclosure (absent a second Board Meeting having to be convened for later this week), approval of the quarterly last Friday would (should) have required release well before now.

So, why hasn't it yet been released? That's the real question that should be asked here, especially building upon a market capturing announcement which refers to unnamed, unmatched, undisclosed revenue over the next 4 years, starting sometime in August (or later), so therefore unlikely to improve upon profitability until into F20 or at least H20.
