Amadeus IT Group confirmed Wednesday it will acquire Idemia Public Security from Advent International for €1.2 billion, the Madrid-listed travel technology company's first move outside its core reservation and distribution business in two decades. The deal, expected to close in Q2 2025 pending regulatory approval, brings 4,200 employees and border control software used by immigration authorities in 70 countries under Amadeus ownership. Idemia Public Security generated €620 million in revenue in 2024 with EBITDA margins near 18%, according to persons familiar with the financials.

The acquisition marks a structural pivot for Amadeus, which has operated since 1987 as a global distribution system connecting airlines, hotels, and travel agencies. Revenue concentration risk has intensified: 68% of Amadeus's €6.4 billion in 2024 revenue came from airline IT and distribution, a segment that shrank 9% year-over-year as carriers built direct booking channels. Idemia's biometric passenger processing technology—facial recognition gates, automated border control kiosks, digital travel credentials—sits upstream of the travel transaction, capturing governments and airport authorities as new buyer categories. The unit's order backlog stood at €1.1 billion at year-end, with contract tenors averaging 7.3 years.

Advent International acquired the broader Idemia identity business for €3.65 billion in 2022, then split it into Public Security and Financial Services divisions in early 2024. Advent retains the payments-focused card manufacturing and digital banking arm. The Public Security unit Amadeus is buying holds contracts with the U.S. Customs and Border Protection, the UK Home Office, and the EU's Entry/Exit System rollout, which begins phased deployment in October 2025. That timing is not incidental—Amadeus will inherit responsibility for system integration across 27 EU member states while absorbing a business whose operating rhythm runs on multi-year government procurement cycles, not the quarterly booking volatility Amadeus has managed for decades.

The deal multiple sits at 1.94x trailing revenue and roughly 10.8x EBITDA, a discount to pure-play identity tech comparables but a premium to Amadeus's own trading range of 8.2x forward EBITDA. Amadeus will fund the purchase with €900 million in new debt and €300 million in cash, lifting its net leverage ratio from 1.1x to 2.6x pro forma. The company has committed to returning leverage below 2.0x within 18 months, implying either accelerated free cash flow conversion or selective asset sales. Idemia's recurring revenue—74% of total, tied to maintenance contracts and software-as-a-service modules—should stabilize cash generation, but government payment terms average 90 days longer than airline settlements.

Operators should track three near-term integration risks. First, Idemia's largest contract, a €240 million border system modernization for an undisclosed Middle Eastern government, comes up for renewal in Q4 2025. Second, the EU Entry/Exit System launch in October carries €85 million in penalty clauses if biometric kiosks fail interoperability tests across Schengen borders. Third, Amadeus must decide whether to retain Idemia's 12 R&D centers or consolidate into its existing labs in Munich and Bangalore, a choice that will determine whether it can cross-sell identity verification into airline direct channels by 2026. The company has not disclosed retention terms for Idemia's executive team.

Advent International exits with a 1.6x gross multiple on its Public Security carve-out after holding the asset for 33 months, below the firm's 2.2x median for European tech exits since 2020 but fast enough to return capital before its Fund IX hits its fifth anniversary in March 2026.
