Airbus Presses Ahead on Two Fronts: Cyber Acquisitions and A321XLR Debut

Airbus acquires Quarkslab for cyber defense, delivers A321XLR to Air Canada, and sees record defense orders, while stock falls 16% in 2025.

Airbus is juggling a tale of two narratives this spring. On one side, the aerospace giant is rapidly stitching together a European cybersecurity network through a string of acquisitions. On the other, it has finally delivered the first A321XLR to Air Canada, marking a long-awaited milestone for the ultra-long-range narrowbody program. Yet the stock, trading at €41.20, has shed nearly 16% since the start of the year — a disconnect that investors are watching closely ahead of first-quarter results.

A Second Cyber Deal in a Month

The latest move in Airbus’s digital defense push came on April 21, when the company announced plans to acquire Quarkslab, a French cybersecurity specialist founded in 2011. The firm, which employs around 100 people, developed QShield, a product designed to protect software and hardware from attacks involving artificial intelligence and reverse engineering. The deal is expected to close later this year, pending regulatory approval. Financial terms were not disclosed.

This marks the second cyber-related acquisition in just over a month. In March 2026, Airbus announced the purchase of UK-based Ultra Cyber, following the integration of Germany’s Infodas in 2024. The strategy is clear: build a pan-European cybersecurity network spanning France, Germany, the UK, Spain, and Finland. The defence and space division is increasingly becoming a reliable growth engine beyond the core commercial aircraft business.

Record Orders in Defence

The defence segment’s momentum is hard to ignore. Last year, order intake hit a record €17.7 billion, while revenue grew by double digits to €13.4 billion. The book-to-bill ratio stood at a comfortable 1.3, meaning new orders are outpacing deliveries by a wide margin. That backlog provides a solid foundation for further investment in areas like cybersecurity.

A321XLR Finally Reaches a Customer

Meanwhile, in the commercial aircraft division, the A321XLR has reached a key customer. Air Canada took delivery of its first example in Hamburg at the end of April, becoming the first Canadian operator of the extra-long-range variant. The jet, leased from SMBC Aviation Capital, is the first of 30 firm orders placed by the airline.

The delivery came later than planned. When Air Canada ordered the aircraft in early 2022, it expected first delivery in the first quarter of 2024. Certification delays pushed that timeline back by more than two years. The A321XLR can fly up to 4,700 nautical miles while burning nearly a third less fuel per seat than older models. Air Canada plans to deploy the aircraft on routes from Montreal to Palma de Mallorca starting in June, with Berlin, Nantes, Toulouse, and Edinburgh to follow later. The airline is equipping the narrowbody with lie-flat beds — a first for a single-aisle jet in its fleet. It also holds options for ten more A321XLRs and has ordered eight A350-1000s to modernise its widebody fleet.

A Backlog That Speaks for Itself

The A321XLR has proven to be a commercial success. Industry-wide orders for the type have surpassed 500 units. The model bolsters Airbus’s already dominant position in the single-aisle market, which accounts for nearly three-quarters of the company’s total backlog. As of the end of March, the order book stood at more than 9,000 aircraft — enough to keep production lines busy for over a decade.

Airbus is targeting 870 deliveries this year, despite persistent supply chain disruptions and engine bottlenecks at Pratt & Whitney. Management has reaffirmed its full-year guidance for adjusted operating profit of around €7.5 billion and free cash flow of approximately €4.5 billion.

What the Market Is Watching

The stock’s recent slide has pushed the relative strength index to around 11, a reading that signals deeply oversold conditions. Investors remain focused on near-term risks — supply chain issues and engine shortages — rather than the strategic progress being made on both the defence and commercial sides. The upcoming first-quarter results will be closely scrutinised for signs that the defence division’s strong momentum can help underpin, or even lift, the full-year earnings forecast.
