Grayscale's Zcash ETF (ZCSH) has filed with the U.S. SEC to implement a 1-for-3 share split after market close on September 28. Under the terms of the split, shareholders will receive two additional shares for every one share held. The fund's per-share price will decline proportionally while outstanding shares increase, ensuring the total value of investor holdings remains unchanged. The adjustment aims to modify the share structure without impacting overall fund valuation.
