In my opinion, if 3M requires an extension, they would have known it way before the deadline and requested for one before the expiry. Like the last extension, it was done a few days before deadline.

Now that the testing period has expired, we should get a straight answer from 3M.

Comparing to a week ago, I believe the chance of success has increased. Before we have 3 possibility of results which 2 of those (extension and No) would react negatively on SP. Now extension is off the table (IMO), only 2 possibilities left. So effectively assuming 33% chance for every outcome, we now have 50% chance of a good result.

I have changed my sentiment from none/hold to buy. Not that it matters since you probably would not get a chance to top up prior to the imminent announcement.
