The new Chairman of the Board Charles Evans offered investors the following commentary on the sweeping changes: The Board is confident that now is the right time for MiMedx to transition its leadership team as we look to the future and prepare our Company for its next chapter. David brings years of valuable executive leadership and operational experience, and we are pleased to have him in this interim role at MiMedx, a global biopharmaceutical company serving clinicians and improving patients' lives around the world. Interim CFO Edward Borkowski also did his best to remind investors the company is in good financial shape: MiMedx has no outstanding debt, and currently has sufficient liquidity to fund all of our operational needs and planned business investment activities. The Company continues to implement operational improvements, expand its product pipeline, grow its business, and remains focused on healthcare providers and their patients. I look forward to partnering with David as we continue to execute our plan for the future. Given the slew of negatives updates, it isn't surprising to see that shares are being mauled today. Now what Today's update provides further validation that MiMedix Group's stock is far too troubled to touch. My plan is to watch this slow-moving train wreck from the safety of the sidelines and focus my time and attention on other opportunities. 10 stocks we like better than MiMedx GroupWhen investing geniuses David and Tom Gardner have a stock tip, it can pay to listen.
