I'm not familiar with this SPAC or the company they are merging with but here are some points to think about.

The valuation can be tricky. The spac usually only makes up a percentage of the company they are acquiring. Figuring out shares before the merger is sometimes a pain in the azz.
There's a chance the merger will not go through, needs to be voted on by shareholders.
Different spacs us different contracts pay attention to lock up periods and who can sell how much
Understand what your buying, Units vs warrants vs shares. and fees from brokers for converstion
There's usually a sell off after merger announcement as the early holders take profits to move to another spac. Then a run up into merger vote, and then another sell off after merger vote. If it's a good company and good valuation then sell offs will be short lived.
