Avio S.p.A. (BIT: AVIO), the Italian aerospace and defense group listed on the STAR segment of Euronext Milan, witnessed a strong surge in its stock price after releasing its half-year 2025 results. The shares closed at €39.90 on September 12, 2025, marking a 12.7 percent increase from the previous day’s close and a gain of 14.1 percent since market open. Investors responded positively to a combination of solid revenue growth, operational milestones in the Vega C and Ariane 6 programs, and a series of defense propulsion contracts that signal Avio’s expanding strategic role in Europe and beyond.
Why did Avio’s stock price rise sharply after the publication of first half 2025 results?
The company’s first-half performance was underpinned by both strong top-line growth and operational execution. Net revenues for the six months ending June 30, 2025, rose to €234.9 million, representing a 30 percent increase compared with €180.6 million in the same period a year earlier. This improvement was driven by higher production rates for the Vega C launcher following its return to flight, additional output of the P120 motors used in the Ariane 6 program, and increasing contributions from defense propulsion activities.
Reported EBITDA climbed to €10 million, up 23.7 percent year on year, while adjusted EBITDA reached €11.4 million, marking a 36.7 percent increase. Although the group still reported a small net loss of €0.2 million, the improvement from the €1.8 million net loss a year earlier reflects both the strengthening of operational cash flows and better absorption of fixed costs. Importantly, Avio reaffirmed its 2025 full-year guidance, which calls for revenues between €450 million and €480 million, EBITDA in the €27–33 million range, adjusted EBITDA of €30–36 million, and net income between €7 million and €10 million.
The reassurance on guidance was well received in the market, as it signaled management’s confidence in sustaining the current growth trajectory despite cost inflation pressures and geopolitical uncertainties affecting both the aerospace and defense industries.
How do the Vega C missions and Ariane 6 launches underpin Avio’s role in Europe’s launcher industry?
One of the main highlights for Avio in the first half of 2025 was the successful execution of two Vega C missions within just three months. On April 29, 2025, mission VV26 deployed the European Space Agency’s Biomass satellite, the first P-band synthetic aperture radar spacecraft designed to study global forest biomass. On July 26, 2025, mission VV27 further demonstrated Vega C’s flexibility by placing five satellites at different altitudes. These included four CO3D satellites built by Airbus Defence and Space, aimed at providing high-resolution three-dimensional mapping of Earth’s surface, and CNES’s MicroCarb satellite, dedicated to monitoring carbon dioxide sources and sinks.
The Ariane 6 program also progressed during the period, with two launches in March and August 2025. Avio plays a critical role as a supplier of the P120C boosters and liquid oxygen turbopumps for both the Vulcain 2.1 core stage engine and the Vinci upper stage. The March mission successfully placed the CSO-3 satellite into orbit for the French Armed Forces, while the August launch deployed the Metop-SGA1 satellite for EUMETSAT. These missions not only validate the Ariane 6 platform but also reinforce Avio’s position as a key industrial partner in Europe’s heavy-lift launch ecosystem.
Technological innovation also contributed to strengthening Avio’s market position. In April 2025, the P160C motor, a next-generation booster co-developed with ArianeGroup through their Europropulsion joint venture, underwent a successful qualification firing test. Containing 157 tons of propellant, the P160C is one of the world’s largest carbon-fiber composite solid fuel boosters and will serve as a common building block for both Ariane 6 and Vega C/E launchers. Avio also completed testing of the MR10 motor in August 2025, further broadening its propulsion portfolio.
Why is the expansion into defense propulsion viewed as a strategic breakthrough for Avio?
The defense propulsion segment is emerging as an increasingly important growth driver for Avio. In Europe, the company reinforced its partnership with MBDA, the pan-European missile systems group, through €60 million worth of new production orders secured in France. In the United States, Avio signed a multi-year supplemental agreement with the U.S. Armed Forces to supply tactical missile solid rocket motors, covering manufacturing, assembly, integration, and testing capabilities.
The expansion into defense activities is strategically significant for two reasons. First, it diversifies revenue streams beyond space launch services, which are inherently cyclical and exposed to competitive dynamics from both private and state-backed operators. Second, defense propulsion contracts typically offer longer order visibility, better pricing stability, and stronger margins. This diversification is increasingly valued by institutional investors who prefer aerospace companies with balanced exposure to both civil and defense end-markets.
How have institutional sentiment and shareholder actions shaped the recent rally in Avio’s share price?
Investor sentiment was also buoyed by shareholder support. In the second quarter of 2025, Space Holding S.r.l., a long-term investor in Avio, exercised 800,000 sponsor warrants at €13 per share. This transaction injected €10.4 million in fresh equity and lifted Avio’s share capital to €91.8 million. The exercise was viewed as a confidence vote from a key shareholder, particularly at a time when Avio is scaling up both its space and defense operations.
As of June 30, 2025, the company held 985,747 treasury shares, equal to 3.63 percent of total capital. These holdings give Avio financial flexibility, either for potential buybacks or for structured equity financing if needed.
From an institutional flows perspective, market data suggests that foreign institutional investors have been increasing allocations to European defense-aerospace equities amid heightened geopolitical risk. The confirmation of Avio as the official launch service provider for the Vega launcher family under the European Space Agency’s new Launchers Exploitation Declaration, together with the ten-year administrative license granted by the French government to operate Vega launches from the Guiana Space Centre, further strengthen the company’s institutional profile and reinforce its strategic importance to Europe’s space autonomy.
How do Avio’s financial fundamentals compare to other European aerospace and defense firms?
On a balance sheet basis, Avio closed June 2025 with an order backlog of €1.67 billion, broadly stable compared with December 2024, ensuring visibility for the next several years. While this backlog may appear modest compared to aerospace giants such as ArianeGroup or Safran, it remains sizeable relative to Avio’s revenue base and provides a solid foundation for continued growth.
Operating margins continue to lag behind larger peers, with EBITDA margins of just over 4 percent in the first half of 2025. However, adjusted EBITDA showed meaningful improvement, supported by higher throughput and disciplined cost control, even as energy inflation weighed on expenses.
Avio’s net cash position of €75.3 million, although down from €90.1 million at the end of 2024, remains a reassuring buffer. The decline was primarily driven by working capital timing, particularly delays in the flow-down of advances to suppliers and subcontractors. Compared to 2024, cash flow from operations showed improvement, narrowing the outflow despite increased investments in new propulsion technologies.
The company’s capital expenditure of €5.2 million in the first half of the year was directed toward property, plant, equipment, and propulsion system development, underscoring its ongoing commitment to innovation in both solid and cryogenic propulsion.
What is the outlook for Avio’s stock following the September 2025 rebound?
Looking ahead, Avio’s performance in the stock market will likely depend on three key factors: the continued cadence of successful Vega C launches, execution of defense propulsion contracts in both Europe and the United States, and delivery against its confirmed financial guidance.
The granting of a ten-year license to operate Vega launch services from the Guiana Space Centre represents a historic milestone, as it is the first time an Italian company has been entrusted with such authority. This is not only a recognition of Avio’s technological capabilities but also a strategic step toward Italy’s deeper integration in the European space sector.
Chief Executive Officer Giulio Ranzo noted that 2025 is a year of consolidation, building on the breakthrough achievements of 2024 and laying the foundation for a new growth phase. For investors, the outlook appears balanced: while margins are still below those of larger European aerospace peers, the combination of rising revenues, expanding defense exposure, and improved visibility on launch operations has led several analysts to signal a buy-on-dips approach.
The upcoming shareholders’ meeting on October 23, 2025, where the appointment of new Chief Financial Officer Roberto Carassai will be formalized and sustainability reporting mandates will be addressed, could provide further governance clarity. Such developments may strengthen investor trust at a time when environmental, social, and governance (ESG) factors are increasingly influencing institutional investment decisions.
