DroneShield Ltd (ASX: DRO)
According to a note out of Bell Potter, its analysts have retained their buy rating on this counter-drone technology company's shares with a reduced price target of $2.50. This follows the release of a trading update which revealed that revenue is expected to be $250 million to $270 million in FY 2026. Bell Potter was disappointed, noting that the consensus estimate is for revenue of $323 million. However, it remains positive on the company's outlook. It continues to expect contract wins, particularly from Europe where DroneShield has a leading presence in the C-UAS EW vertical, which is supported by high moat next-gen products. The DroneShield share price ended the week at $1.70.
Mineral Resources Ltd (ASX: MIN)
A note out of Morgans reveals that its analysts have upgraded this mining and mining services company's shares to a buy rating with a $68.00 price target. The broker notes that Mineral Resources delivered a strong fourth-quarter result, with production and cost beats across mining services, iron ore, and lithium. It was also pleased to see that FY 2026 guidance was achieved or exceeded across every segment. Another positive was that Mineral Resources' net debt reduced to $4.3 billion, which was 8% below expectations. In light of this, the broker sees value in the company's shares at current levels. The Mineral Resources share price was fetching $57.98 at Friday's close.
WiseTech Global Ltd (ASX: WTC)
Analysts at Macquarie have retained their outperform rating on this logistics software provider's shares with a reduced price target of $47.10. According to the note, the broker believes that WiseTech Global's near-term outlook has improved and expects its FY 2027 guidance to exceed consensus estimates on stronger revenue and lower operating costs. Macquarie also sees potential for upside to revenue estimates from customer migrations to the CargoWise Value Pack. The WiseTech Global share price ended the week at $36.30.
