Electro Optic Systems Holdings Ltd (ASX: EOS)
The EOS share price is up 7% to $9.60. This morning, this ASX defence stock announced that it has secured new remote weapon system (RWS) orders valued at approximately $17 million. It notes that the largest component is a US$12 million order for R400 RWS units from an established Middle Eastern government customer. The company also revealed that it has finalised a $100 million two-year secured term loan facility. This will support growth across the business, provide additional working capital, and help fund payments related to the acquisition of MARS.
Lynas Rare Earths Ltd (ASX: LYC)
The Lynas share price is up 5% to $20.00. This has been driven by news that Lynas has received a letter from the Malaysian Department of Atomic Energy confirming that the Lynas Malaysia operating licence has been renewed for 10 years. The company's CEO, Amanda Lacaze, said: "Lynas welcomes the longer licence term which provides greater investment certainty for Lynas and for our rare earths supply chain partners and customers. On behalf of all Lynas employees, we thank the Malaysian Government for its attention to this matter and its support for the rare earths industry in Malaysia."
Woodside Energy Group Ltd (ASX: WDS)
The Woodside share price is up 4.5% to $29.60. Investors have been buying Woodside and other ASX energy shares on Monday after war in the Middle East sent oil prices racing higher. According to Bloomberg, in Asian trade, both Brent crude oil and WTI crude oil prices have jumped over 5.5%. Some analysts believe oil prices could creep towards US$100 a barrel if the war drags on.
