4DMedical Ltd (ASX: 4DX)
The 4DMedical share price is down 12% to $4.01. This may have been driven by profit-taking from investors after some very strong gains in 2025. For example, the respiratory imaging technology company's shares are up over 700% since this time last year despite today's pullback. The catalyst for this has been the US FDA's approval of its CT:VQ platform. It is a CAT scan-based ventilation-perfusion software. In addition, the platform has been picked up by three of America's leading academic medical centres since approval. This includes Stanford, University of Miami, and Cleveland Clinic. Management believes the "rapid adoption by elite institutions demonstrates the compelling clinical and operational advantages of CT:VQ over traditional nuclear VQ imaging."
Coronado Global Resources Inc (ASX: CRN)
The Coronado Global share price is down 12.5% to 31.5 cents. This has been driven by the tragic news that the coal miner has experienced its second fatality on-site in less than a month. In the middle of the month, one occurred at its Logan mining complex in West Virginia, United States. On Friday, a second incident occurred at the Mammoth Underground Mine, which is located within Coronado Global's Curragh Mine complex, resulting in a fatal injury to an employee.
Metallium Ltd (ASX: MTM)
The Metallium share price is down 7% to 98.7 cents. This is despite the company announcing a binding electronic-scrap supply agreement with Glencore (LSE: GLEN). It is a major recycler of end-of-life electronics, lithium-ion batteries, and other critical metal-containing products. Management notes that the agreement marks a significant commercial milestone for Metallium, providing secure long-term access to e-scrap feedstock to support the ongoing commissioning and scale-up of its Flash Joule Heating (FJH) technology platform in the United States.
WiseTech Global Ltd (ASX: WTC)
The WiseTech Global share price is down 3.5% to $66.10. Investors have been selling WiseTech Global shares despite there being no news out of the logistics solutions technology company. However, it is worth noting that a number of ASX tech stocks have taken a tumble on Monday. This has led to the S&P/ASX All Technology Index falling 2.2% this afternoon.
