Electro Optic Systems Holdings Ltd (ASX: EOS)
The EOS share price is down 4.5% to $10.22. Investors have been selling the defence and space company's shares after it revealed that the Australian Securities Exchange (ASX) has reviewed its continuous disclosure practices. The ASX has formed the view that a previous announcement by EOS on 15 December 2025 regarding a conditional US$80 million high-energy laser contract failed to adequately describe market sensitive information. The stock exchange operator has directed EOS under Listing Rule 18.8(k) to review its continuous disclosure policy.
GQG Partners Inc (ASX: GQG)
The GQG Partners share price is down a further 2.5% to $1.76. The fund manager's shares have dropped this week following the release of its latest funds under management (FUM) update. GQG Partners reported a 4.3% increase in FUM to US$172.9 billion during the month of February. However, this was driven by investment performance, which offset net outflows of US$3.2 billion. The company's net outflows were recorded across all strategies.
Liontown Ltd (ASX: LTR)
The Liontown share price is down 2.5% to $1.59. This has been driven by the release of the lithium miner's half-year results. Although Liontown more than doubled its revenue to $207.5 million, it recorded a statutory net loss after tax of $184 million. Commenting on its performance, Liontown's CEO, Tony Ottaviano, said: "Kathleen Valley is now a 100% underground operation. We have delivered a one million tonne per annum underground run-rate on schedule, sold 190,000 tonnes of concentrate across ten shipments, and more than doubled revenue period to period. The underground ramp-up is on track and we expect the second half to be materially stronger as volumes, recoveries, and pricing all continue to improve."
Temple & Webster Group Ltd (ASX: TPW)
The Temple & Webster share price is down almost 8% to $6.82. This may have been driven by concerns over how the war in the Middle East could impact the online furniture and homewares retailer. With shipping costs surging, there are fears this could hit its profitability in the second half of FY 2026.
