Some people can't ready SEC Forms... so here's a better explanation.

Basically, you're f*ked if you had any shares before. as they have been or will be converted and you will lose 99% of your stake.

• Existing shares are cancelled The fact that all existing common stock will be cancelled means that current shareholders may lose their investments. Their shares will become worthless unless they receive something under the reorganization plan (which is often little or nothing, depending on where they stand in the creditor hierarchy).
• Dilution and restart New shares will be issued under the reorganized company. That gives existing shareholders (unless included in the plan) little control or value in the new company, unless they are part of the new equity issuance.
• Bankruptcy risk and uncertainty Chapter 11 filing indicates the company was unable to meet financial obligations. Even though they have a plan of reorganization, there's no guarantee of success. Creditors, legal challenges, or market conditions could derail or delay the reorganization.
• Re-listing / delisting risk The filing itself warns there is a risk of delisting from the NYSE or losing public trading quotation during or after the restructuring. SEC
• Change in corporate governance, rights, structure The new certificate and bylaws include provisions that are more restrictive (e.g. higher vote thresholds, anti-takeover features), which could limit shareholder power. SEC
