Dr. Robin L. Smith, Chairman and CEO of NeoStem stated, “Over the last few months we have had numerous discussions with investors, advisors and our board about our capital structure. We have also observed that, over the past five years, a number of our peer companies in the regenerative medicine sector have effected reverse stock splits. We believe the resulting increase in share price will demonstrate the true value of NeoStem’s common stock and broaden the appeal of our shares to investors, particularly institutional stockholders.”
