Investors like news and/or financials.
This is typical reaction, although this is great news for longs like most of us, the fact that this is just closing a deal most expected to happen anyway won't likely vault the price today or even this week, it's not the big news that investors were probably hoping for...but this lays the groundwork for future growth and more stability in the future PPS.
Just will need more news to follow to push this higher, this news is not enough at this point unfortunately.
