Company News
L3Harris Technologies has demonstrated solid financial performance with earnings per share growing 16% annually over the past three years. The US$66 billion defence contractor reported revenue of US$22 billion, up 2.5%, whilst maintaining stable EBIT margins. Company insiders hold US$220 million worth of shares, representing 0.3% of the company. Whilst modest in percentage terms due to L3Harris's size, this stake provides alignment between management and shareholders. The company's combination of revenue growth, profit expansion and insider ownership distinguishes it from speculative, loss-making ventures. Its established track record of profitability offers investors lower risk compared to companies relying solely on growth narratives without financial substance. The article suggests L3Harris warrants consideration for investors seeking profitable, growing companies over high-risk ventures.
L3Harris Technologies has raised investor attention following recent share price movements, with the stock up 2.3% over the past week. The company has delivered strong longer-term returns, including a 71.8% one-year total shareholder return and 92.9% over three years. With revenue of $21.9 billion and net income of $1.6 billion, L3Harris is trading at $361.97. One valuation narrative suggests the stock is modestly undervalued at a fair value of $392.16, supported by expected US defence budget growth and the company's positioning in areas like missile warning and tracking. However, L3Harris' current price-to-earnings ratio of 42.1x sits above the US aerospace and defence industry average of 38.8x, suggesting potential valuation risk if market sentiment shifts.
Xoople, an AI data infrastructure company, and L3Harris Technologies have announced the co-development of a satellite constellation optimised for AI applications. The system, resulting from seven years of design and research, aims to deliver unprecedented precision in Earth observation data. The constellation features advanced optical and sensor design to maximise data quality, providing what Xoople calls "Earth's System of Record". The platform is designed to support AI systems shifting towards autonomous action, offering real-time monitoring with precision levels where even 1% error is unacceptable. Applications include supply chain optimisation, infrastructure management, risk underwriting, disaster response and security monitoring. CEO Fabrizio Pirondini said the system delivers the scale and precision required for AI-era decision-making across enterprises and governments.
L3Harris Technologies supplied propulsion, avionics, thrusters and communications systems for NASA's Artemis II mission, the first crewed lunar journey in over 50 years. The company's involvement spans more than 100 mission elements, highlighting its capabilities in space hardware and systems integration for government programmes. Whilst the Artemis II role demonstrates L3Harris's technical breadth, analysts note it does not materially alter the near-term investment case. The company faces ongoing risks from fixed-price development contracts and potential US space budget constraints that could pressure margins. L3Harris's investment narrative projects $27 billion in revenue and $2.9 billion in earnings by 2029, requiring 7.3% annual revenue growth. Community analysts estimate fair value between $388 and $452 per share.
US Defense Secretary Pete Hegseth plans to request $200 billion from Congress to fund operations against Iran, adding to the Pentagon's roughly $1 trillion budget for the current fiscal year. Two defence stocks well-positioned to benefit from this spending increase are Axon and L3Harris, according to Barchart. Axon, which provides law enforcement equipment including Tasers and AI-driven systems, reported 39% revenue growth to $797 million in Q4. The company's AI-powered tools are particularly relevant given recent suspected terrorist attacks in the US. L3Harris, a defence contractor selling missiles, satellites and communications products, saw 6% revenue growth to $5.6 billion last quarter, whilst cash from operations jumped 74% year-over-year. Analysts predict Axon's earnings per share will rise 13% this year and 115% in 2027.
