DroneShield Ltd (ASX: DRO)
The DroneShield share price is up 5% to $3.23. This is despite there being no news out of the counterdrone technology company. However, with its shares pulling back meaningfully in recent weeks, some investors may believe a buying opportunity has opened up. In addition, some investors may think that rising tensions in the Middle East could lead to increased demand for its products in the near term.
Select Harvests Ltd (ASX: SHV)
The Select Harvests share price is up 10% to $4.25. This may have been driven by the release of a bullish broker note out of Bell Potter this morning. According to the note, the broker has reaffirmed its buy rating on the almond producer's shares with an improved price target of $5.45. Commenting on its buy recommendation, the broker said: "Buy rating is unchanged. Volatility in almond pricing has been a feature since May'25. However, the long-term under development of orchards in California implies a period of limited supply expansion potential, which we view as a positive for the direction of future almond pricing trends. Trading at ~7% discount to market NAV, ~5.9x FY26e "spot price" EBITDA and ~9.3x FY26e "spot price" PER (@29kt production), valuation is undemanding, particularly if pricing continues to firm."
Tower Ltd (ASX: TWR)
The Tower share price is up almost 10% to $1.58. The catalyst for this has been news that the insurance company has updated its guidance for FY 2025. Tower's underlying net profit after tax is now expected to be in the range of between NZ$100 million to NZ$110 million, provided that no large events are recorded in September. Its previous guidance was for underlying net profit after tax of between NZ$70 million and NZ$80 million.
Ventia Services Group Ltd (ASX: VNT)
The Ventia Services share price is up 5% to $5.29. This morning, this essential infrastructure services provider announced the extension of its Facility Management Agreement with the City of Sydney, valued at approximately $100 million over two years. This extension will commence on 22 January 2026 and continue through to 21 January 2028. Management believes it reinforces the City of Sydney's continued confidence in Ventia's ability to deliver high-quality, data driven and strategic asset management services across its diverse asset portfolio.
