Sonoma Pharmaceuticals said it has begun selling its hypochlorous-acid (HOCl) diaper-rash hydrogel for infants and children at roughly 3,600 Walmart locations and select U.S. grocery chains. The over-the-counter product is the company’s first large-scale consumer launch and is based on Sonoma’s patented Microcyn antimicrobial technology. The announcement sent Sonoma’s thinly traded stock up as much as 107% in pre-market dealings on Thursday, reflecting investor enthusiasm for the broadened retail footprint. In a separate development, bitcoin-miner-turned-computing-services firm TeraWulf signed two ten-year colocation agreements with cloud platform Fluidstack covering more than 200 megawatts of high-performance computing capacity. The arrangement includes warrants that allow Google to acquire about 41 million TeraWulf shares, helping lift the stock roughly 27% in early trading.
