The All Ordinaries index was on form in May and charged higher. Over the course of the month, the index rose by a sizeable 3.8% to end the period at 8,660.3 points.
While most ASX All Ords shares climbed with the market, some delivered stronger gains than others.
For example, listed below are the best-performing ASX All Ords shares in May. Here's how they performed:
Life360 Inc (ASX: 360)
The Life360 share price was the best performer on the All Ordinaries index with a gain of 51% last month. This was driven by the location technology company's impressive first quarter update. Life360 posted a 32% increase in revenue over the prior corresponding period to US$103.6 million. A key driver of this was a 37% jump in core subscription revenue to US$76.2 million. Growing even quicker was Life360's adjusted EBITDA, which more than tripled to US$15.9 million. Commenting on the quarter, CEO Chris Hulls, said: "Life360 started 2025 strongly, achieving record highs in MAUs, subscribers, and Q1 net additions, while making meaningful progress against our strategic roadmap."
Electro Optic Systems Holdings Ltd (ASX: EOS)
The Electro Optic Systems share price wasn't far behind with a gain of 50% in May. Investors were fighting to get hold of this defence and space systems company's shares after it announced that it had won a major counter-drone contract. EOS revealed that it won a new order for Remote Weapon Systems worth 31 million euros (A$53 million). The company noted that the order is from a European naval systems integration business and is for its flagship "Slinger" Counter-Drone Remote Weapon System (RWS). The systems will be configured for naval deployment.
Appen Ltd (ASX: APX)
The Appen share price was on form and also recorded a gain of 50% last month. The catalyst for this was the artificial intelligence data services company's guidance update at its annual general meeting. At the event, Appen revealed that it is expecting revenue between $235 million and $260 million. This implies flat to 10.9% growth for the year. It also expects positive underlying EBITDA for FY 2025. A rebound in AI stocks last month also gave the ASX All Ords share a boost.
Catapult Group International Ltd (ASX: CAT)
The Catapult Group share price was a strong performer and rose 43% during the period. This was driven by the release of the sports technology company's stellar full year results. Catapult recorded a 19% increase in revenue to US$116.5 million and an 18% lift in annual contract value (ACV) to US$101.2 million. This underpinned the more than tripling of EBITDA to US$14.8 million. A bullish broker note out of Morgan Stanley at the end of the month also gave the ASX All Ords share a further lift.
