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 $4.80. This follows the release of full-year results that were strong, but just a touch short of expectations due to a weaker-than-expected gross margin. Nevertheless, Bell Potter remains very positive. It once again highlights that the company has a market-leading offering and a strengthening competitive advantage owing to its years of battlefield experience and large and focused R&D team. It is also expecting 2026 to be an inflection point for the global C-UAS industry with a wave of spending on solutions. As a result, it believes DroneShield should see material contracts flowing from its $2.3 billion potential sales pipeline over the next three to six months. The DroneShield share price is trading at $3.64 on Friday.
Jumbo Interactive Ltd (ASX: JIN)
A note out of Morgans reveals that its analysts have retained their buy rating and $14.90 price target on this lottery ticket seller's shares. Morgans was pleased with Jumbo's performance in the first half, noting that it delivered a solid result. In addition, it was pleased to see that managed services continues to build momentum and that underlying SaaS trends remain healthy. Another positive is that Morgans believes the company can de-lever its balance sheet in FY 2027, leaving it well-placed for the remainder of the decade. The Jumbo share price is fetching $9.78 at the time of writing.
Qantas Airways Ltd (ASX: QAN)
Analysts at Macquarie have retained their outperform rating on this airline operator's shares with a trimmed price target of $12.00. According to the note, Macquarie was pleased with Qantas' performance during the first half. It highlights that the Flying Kangaroo's earnings were ahead of its expectations thanks to strong performances from Jetstar and Qantas Domestic. This reflects new fleet benefits for Jetstar and stronger Domestic yields. Looking ahead, the broker is expecting further earnings growth as Qantas reaps the benefits of its fleet renewal and cost discipline. The Qantas share price is trading at $9.92 this afternoon.
