All perfect praise be to Allah the Lord of The Worlds. May His blessings and peace be upon our Prophet Mohammad and upon all his family and companions.
From an Islamic perspective, some companies comply with the rulings of Sharia while some don`t. Consequently, we can`t rule that a certain company is Sharia compliant or not until after studying its statute.
The ordinary citizen can review the company`s statute and if he finds that it involves usurious transactions or deals with usurious banks, then he/she must abstain from holding shares in that company or could consult a scholar of Sharia as to the best course of action. And Allah the Almighty Knows Best.
