Electro Optic Systems Holdings Ltd (ASX: EOS)

The EOS share price is down 7% to $10.24. This appears to have been driven by profit taking from some investors following strong gains by the defence and space company's shares. In fact, despite today's pullback, EOS shares are up 60% over the past month. The announcement of major new contract wins has been behind this. On a 12-month basis, the company's shares are up a staggering 750%.

Humm Group Ltd (ASX: HUM)

The Humm share price is down 2% to 72.5 cents. This morning, the financial services company's board strongly recommended that shareholders vote against resolutions proposed at an extraordinary general meeting to remove three current directors. It named a number of reasons why. One is: "Replacing the current Board would jeopardise the strategy delivering measurable results, including a ~118% total shareholder return, since mid-2022." Another reason is: "The Convenors' ill-conceived and simplistic 'plan' threatens Humm's capital strength, lender relationships and growth prospects. In contrast, your Board's disciplined approach prioritises sustainable value creation."

Pantoro Gold Ltd (ASX: PNR)

The Pantoro Gold share price is down 2% to $5.27. This appears to have been driven by the release of drilling results from the gold miner's 100%-owned Norseman Gold Project this morning. Pantoro Gold's managing director, Paul Cmrlec, said: "These high-grade results from Daisy South support the development of an additional open pit to be mined at the same time as the Gladstone Everlasting Open Pit, located just 900 metres to the west. Mining the pits simultaneously is expected to improve fleet efficiency and extend the open pit life of the Gladstone Everlasting Mining Centre."

Robex Resources (ASX: RXR)

The Robex Resources share price is down 3% to $6.69. This is despite the gold miner announcing that Superior Court of Quebec has approved its merger with Predictive Discovery Ltd (ASX: PDI). Closing of the transaction remains subject to the satisfaction of the remaining closing conditions. This includes the receipt of the consents of the Governments of Guinea and Mali. But if all goes to plan, the transaction is expected to complete later in the first quarter of 2026.
