Participants have the option of receiving physical share certificates or a DRS statement that representes electronically registered shares with Computershare.  Most opt for DRS, which will be mailed to you.

You would send a copy of that DRS statement to your broker with directions indicating you want those shares transferred into your brokerage account.

For warrants, you would fill out the warrant certificate that is sent to you by Poet, wire them the funds for the amount you are exercising, and then follow the same DRS path as above to get them into your brokerage account.
