Arafura Rare Earths Ltd (ASX: ARU)
The Arafura Rare Earths share price is down 11% to 27.5 cents. The catalyst for this has been news that the rare earths developer has raised $350 million through an institutional placement. The company is raising the funds at a 16.1% discount to its last close price. Arafura's CEO and managing director, Darryl Cuzzubbo, said: "The strong support received for this capital raising is a clear endorsement of the Nolans Rare Earths Project and Arafura's role in building a diversified, Western rare earths supply chain. With this successful result and the Board's recent Final Investment Decision, we look forward to commencing construction of this nationally significant project, which we are targeting in around September 2026."
Dalrymple Bay Infrastructure Ltd (ASX: DBI)
The Dalrymple Bay Infrastructure share price is down almost 2% to $5.50. This has been driven by the terminal infrastructure and services provider's shares going ex-dividend this morning. Earlier this month, the company declared a quarterly dividend of 6.75 cents per share. This will be paid to eligible shareholders next month on 12 June.
Tuas Ltd (ASX: TUA)
The Tuas share price is down a further 4% to $2.22. Last week, this Singapore-based telco terminated its proposed acquisition of M1 Limited. This followed news that authorities had suspended the review of the deal after Tuas' Simba business allegedly used spectrum it did not own. It said: "Simba continues to co-operate with the investigation being undertaken by the Infocomm Media Development Authority into potential breaches of the Telecommunications Act and the conditions of Simba's Facilities-Based Operator Licence. Tuas will keep shareholders updated in relation to that investigation."
Woodside Energy Group Ltd (ASX: WDS)
The Woodside Energy share price is down 4% to $30.84. Investors have been selling this energy producer's shares following a pullback in oil prices on Monday. Traders have been selling oil amid optimism that the US and Iran will soon sign a peace deal and reopen the Strait of Hormuz. It isn't just Woodside shares that are falling on the news. The S&P/ASX 200 Energy index is down 2% at the time of writing.
