4DS Memory Ltd (ASX: 4DS)
The 4DS Memory share price is down 64% to 1 cent. This morning, this semiconductor company revealed that following the conclusion of extensive analysis of its Sixth Platform Lot results, it has resolved to initiate a strategic review of its technology pathway. The review includes a pause in development activities and disengagement of collaborations with imec and Infineon Technologies. Executive chair, David McAuliffe, said: "While the decision to undertake a strategic review is difficult, it is also the right decision. This strategic review is about ensuring that our capital is deployed in a manner which is most advantageous toward creating shareholder value in a fast-moving industry."
Bannerman Energy Ltd (ASX: BMN)
The Bannerman Energy share price is down almost 2% to $3.18. This is despite the uranium developer announcing binding offtake purchase commitments for 1 Mlbs of uranium over five years with two Tier-1 North American generation companies. Management notes that contractual terms under both agreements provide the company with delivery flexibility to preserve Bannerman's capacity for strategic patience ahead of final investment decision at Etango. Bannerman's CEO, Gavin Chamberlain, said: "The signing of these limited, select offtake agreements (the first for Bannerman) with high-quality utility counterparties represents a further important step in our systematic advancement of Etango towards a targeted Final Investment Decision. We are able to demonstrate to potential customers a strong foundation for confidence in our ability to meet future supply commitments."
Coles Group Ltd (ASX: COL)
The Coles Group share price is down over 1% to $23.83. This has been driven by the supermarket giant's shares going ex-dividend this morning for its latest payout. Last month, Coles released its FY 2025 results and declared a fully franked final dividend of 32 cents per share. This will be paid to eligible shareholders later this month on 22 September.
Viva Energy Group Ltd (ASX: VEA)
The Viva Energy share price is down almost 2% to $2.06. This has also been caused by the fuel retailer's shares going ex-dividend this morning. Last month, when the company released its half year results, it declared a fully franked 2.8 cents per share interim dividend. Eligible shareholders can now look forward to receiving this at the end of the month on 30 September.
