The DroneShield share price is up 2% to $3.20. Investors have been buying this counter drone technology company's shares following the release of a sales update. DroneShield revealed that it has surpassed 4,000 systems sold worldwide with the receipt of a package of two standalone contracts totalling $7.9 million for handheld systems for delivery to the U.S. Department of Defense. The company expects to deliver all equipment in the fourth quarter of 2025.

EBR Systems Inc (ASX: EBR)
The EBR Systems share price is up 11% to $1.30. This morning, this medical device company revealed that it has passed the tenth commercial implant of its WiSE System in the United States. This technology has been developed to eliminate the need for cardiac pacing leads, which are historically the major source of complications, effectiveness, and reliability issues in cardiac rhythm disease management. The company's president and CEO, John McCutcheon, said: 'Passing the ten-case milestone so soon after FDA approval reflects strong clinical interest in leadless left-ventricular endocardial pacing and underscores the value EBR's novel WiSE System brings for patients who are not well served by conventional CRT."
Silex Systems Ltd (ASX: SLX)
The Silex Systems share price is up 15% to $4.87. This follows the release of an update from the uranium technology company. It advised that Global Laser Enrichment (GLE), the exclusive licensee of the SILEX uranium enrichment technology, has completed the large-scale enrichment demonstration testing campaign at its Test Loop facility in North Carolina. The good news is that GLE has collected extensive performance data providing confidence that its laser-based uranium enrichment process will achieve TRL-6 demonstration status and can be commercially deployed.
Sunrise Energy Metals Ltd (ASX: SRL)
The Sunrise Energy Metals share price is up a further 15% to $5.02. This scandium developer's shares have been rocketing this week following a big announcement.
