DroneShield Ltd (ASX: DRO)
The DroneShield share price is down 5% to $2.98. This counter-drone technology company's shares have come under pressure this month following the announcement of an ASIC investigation. The company said: "DroneShield advised that it will cooperate fully with the investigation regarding announcements and information provided to the Australian Securities Exchange between 1 and 20 November 2025, and trading in Droneshield shares between 6 and 12 November 2025 (inclusive). […] It is not clear what action, if any, may result from ASIC's investigation."
Lynas Rare Earths Ltd (ASX: LYC)
The Lynas Rare Earths share price is down 4% to $18.10. This is despite there being no news out of the company. However, there are reports that China will soon address U.S. concerns
PLS Group Ltd (ASX: PLS)
The PLS share price is down 4% to $5.75. This appears to have been driven by continued weakness in the lithium industry. This latest decline means that PLS shares are now down 10% since this time last week. Some of this selling could have been due to profit taking from investors. After all, PLS shares are still up over 300% since this time last year.
TechnologyOne Ltd (ASX: TNE)
The TechnologyOne share price is down 4% to $27.54. This follows the release of the enterprise software provider's half-year results. TechnologyOne posted a 9% increase in profit before tax to $89.1 million and a 17% jump in annual recurring revenue (ARR) to $598 million. While this was in line with consensus estimates, it seems that some investors were expecting a surprise to the upside. Commenting on the half, TechnologyOne's CEO, Ed Chung, said: "There is huge momentum and confidence in the business today, in our strategy of SaaS+, which is fuelling the results we delivered today, and allows us to continue to invest into the future. Now with our AI strategy, the adoption of AI and the feedback we are receiving is surpassing our expectations. All of this also gives us confidence in our pipeline and we don't guide up unless we see it day in and day out."
