Here's why, IMO.

As has already been said, the PRs make no mention of the amount. This makes it clear that PTSC is still just along for the TPL ride. Nothing has changed.

Additionally, there is no new information. Nothing to indicate that anything else has changed (end of early mover discounts, ongoing royalties, etc, that everyone wants).

So it is viewed as more of the same. The same that has gotten PTSC to $0.17.

The PRs are viewed as confirmation that it's business as usual and since the market isn't happy with PTSC's business as usual, price goes down or sits flat.
