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 trimmed price target of $2.40. The broker highlights that DroneShield's first-half underlying EBITDA was a material miss. However, Bell Potter points out that its first-half revenue was in line with expectations and its updated committed revenue for FY 2026 now stands at $240 million. It believes that this means DroneShield is likely to achieve the top-end of its guidance range for the year. This is especially the case given the new proprietary RfAI-3 software engine and flagship next-generation RfRecon hardware are generating strong early customer interest. It expects the high-moat next gen products to drive continued contract wins, particularly from Europe. The DroneShield share price ended the week at $1.75.
Sigma Healthcare Ltd (ASX: SIG)
A note out of Morgans reveals that its analysts have upgraded this pharmacy chain operator's shares to a buy rating with a trimmed price target of $3.19. This follows the release of its FY 2026 result, which was in line with expectations. Morgans was also pleased with Sigma's guidance for FY 2027, noting that it is targeting double-digit revenue and earnings growth. In light of this, the broker feels that recent share price weakness is overdone and provides investors with an opportunity to buy shares at an attractive price. The Sigma Healthcare share price was fetching $2.68 at Friday's close.
WiseTech Global Ltd (ASX: WTC)
Another note out of Morgans reveals that its analysts have retained their buy rating on this logistics technology company's shares with a slightly reduced price target of $62.50. It highlights that WiseTech Global delivered a result that was largely in line with its expectations in FY 2026. And while CargoWise revenue growth was softer than expected, it was pleased with the annualised run-rate savings of ~US$115 million. The broker was also pleased to see management guiding to improving margins in FY 2027, which has led to an upgrade to its estimates for the year. The WiseTech Global share price ended the week at $40.61.
