Well first there has been a lot of share conversions from jan-apr. Partly I think they needed to be cleaned up for S1 but also just were converted as they did not have the funds to pay off so that brought share price down quickly with each discounted conversion.
Second the S1 funding came available after the SEC wait period during the week of 5/5-5/9. He confirmed in the May 12th PR that the initial drawdown was used and that those funds went to purchase the equipment to finish the Snyder/Simon rework. Based on the requirements of the S1 funding, CPUS purchased shares as I estimate at about .0003 after their discount.
