$RLYB worth well over 17 USD based on net cash, assuming milestone payment from Recursion in july 2026 (5 mln USD), add the Shell for RM at least 10 mln usd or 1.70 usd per share, stock should be trading around 20 USD. I dont know if pipeline could be sold. I am assuming CVR of new reverse merger engineered. Just my math, this Is not a Financial advice, do your dd before investing your money.
