AGL Energy Limited (ASX: AGL)
The AGL Energy share price is up 9% to $9.65. Investors have been buying this energy giant's shares following the release of its half-year results. Although AGL posted a decline in underlying net profit, it has updated its guidance for FY 2026. The company now expects full-year underlying EBITDA of $2.02 billion to $2.18 billion. This compares to its previous range of $1.92 billion to $2.22 billion. Its underlying net profit guidance was also tightened to $580 million to $680 million, from the previous range of $500 million to $700 million. This reflects improved consumer margins and lower than previously indicated operating costs due to disciplined cost management.
Commonwealth Bank of Australia (ASX: CBA)
The CBA share price is up 8% to $171.38. This has been driven by the release of the banking giant's half-year results this morning. CBA reported a 6% increase in cash net profit to $5,445 million and lifted its interim dividend by 4% to $2.35 per share. CBA's CEO, Matt Comyn, said: "Economic growth strengthened during the half, driven by increases in consumer demand and rising investment in AI and energy infrastructure."
Domino's Pizza Enterprises Ltd (ASX: DMP)
The Domino's share price is up 3% to $22.99. This follows news that the pizza chain operator has appointed its new CEO. Domino's has named experienced global quick service restaurant executive Andrew Gregory as its incoming group CEO and managing director. The company notes that Mr Gregory will start with Domino's once his obligations to his current employer have been discharged. This will be no later than 5 August 2026. He most recently served as McDonald's senior vice president of global franchising, development and delivery in the US.
James Hardie Industries plc (ASX: JHX)
The James Hardie share price is up 12% to $37.20. Investors have been buying this building materials company's shares following the release of its third-quarter update. The company reported a 30% jump in sales to US$1,239.8 million and a 26% lift in adjusted EBITDA to US$329.9 million. This growth was driven largely by the addition of the AZEK business following its recent acquisition. James Hardie's CEO, Aaron Erter, said: "In the third-quarter, we achieved or exceeded each of our financial commitments despite a mixed macro backdrop. We are taking actions to address the current market environment, including optimizing our manufacturing footprint and better aligning our cost structure with the slower, but stabilizing, pace of demand."
