Not excuses, but typically brokers do charge about $500 to get your shares put into certificate form. That used to be much, much cheaper.

Other ways: Your broker is only allowed to loan out your shares with a value up to 140% of your margin balance...so if you don't have any margin debt balance or if your margin balance is minimal, your PTOI shares can't be loaned out. The other thing you can do is open another account and transfer only your PTOI shares into the new account, either a cash account or an account where you won't carry any margin balance.

Keep in mind that NASDAQ says that short interest in PTOI is very minimal (about $80 in total)...and PTOI hasn't been on the Reg SHO threshold list. Preventing your shares from being borrowed likely won't have any impact.

Yes, I understand your penny stock also is the real deal, created with the inventiveness of Edison and destined to be the next Microsoft. Yes, I understand that the delays are also only because your company is making their product and/or technology even more revolutionary.
