Acrow Ltd (ASX: ACF)

The Acrow share price is up 9.5% to 97 cents. This morning, this smart integrated construction systems provider announced that the Industrial Access division's revenues will exceed $200 million for FY 2026. It notes that this represents a significant milestone in the division's growth and profitability. The company's CEO, Steven Boland, said: "Our strategy to build a substantial Industrial Access division to complement our market leading Construction Services division, is delivering strong results. The recurring nature of earnings from this division, combined with its growth trajectory, has delivered at a time when activity in our Construction Services division has softened, ensuring that the Company continues to prosper."

Ampol Ltd (ASX: ALD)

The Ampol share price is up 2% to $34.53. This has been driven by news that the Australian Competition and Consumer Commission (ACCC) has approved its acquisition of EG Australia. As part of the deal, Ampol has agreed to sell 41 sites to Metro Petroleum. Ampol's CEO, Matt Halliday, said: "This transaction is a major step in delivering Ampol's strategy by strengthening our retail network and enhancing our segmented customer offer. The performance of our existing U-GO sites also gives us greater confidence in delivering the expected synergies from the transaction and creating value for Ampol shareholders."

Medallion Metals Ltd (ASX: MM8)

The Medallion Metals share price is up 11% to 45 cents. This morning, this gold explorer announced more exceptional high-grade gold results from the Lounge Lizard deposit at the Forrestania Gold Project (FGP). The company's managing director, Paul Bennett, commented: "This latest phase of validation continues to strengthen our understanding of the Lounge Lizard mineralised system and the continuity of high-grade mineralisation beneath the historical open pit."

Northern Star Resources Ltd (ASX: NST)

The Northern Star share price is up 5% to $22.10. Investors have been buying this gold miner's shares after it announced its latest mineral resource and ore reserve estimate. Northern Star revealed that its group mineral resources have increased to 88.9 million ounces. This represents an increase of 18.2 million ounces, or 26%, after mining depletion. A key driver of this increase was the first inclusion of the Hemi Project following Northern Star's acquisition of De Grey Mining.
