Açores Government Opens the SATA Internacional / Azores Airlines Sale With a 75% Minimum-Stake Floor — Caderno de Encargos Locks In 30-Month No-Layoff Cover, São Miguel-Terceira-Lisboa-Porto Routing and a Three-Year AOC

The Governo Regional dos Açores opened the private-negotiation phase of the SATA Internacional / Azores Airlines reprivatisation on 21 May 2026 with the publication of the caderno de encargos, the binding terms-of-reference document that sets out what bidders must agree to before any share transfer can complete. The new structure follows the failure of the March 2026 public-tender attempt — the one that had allowed a 51-85% range — and replaces it with a single, harder floor: at least 75% of the share capital of SATA Internacional must change hands. The European Commission's restructuring decision keeps the underlying deadline at end of 2026, leaving the Açores executive roughly seven months to close.

What the 75% floor actually buys

The caderno de encargos pairs the minimum stake with a series of operational and labour commitments that the winning bidder must hold to for a defined transition window. The key bindings:

• 30-month no-layoff cover: no collective dismissals (despedimentos coletivos) and no extinction of existing positions during the first 30 months after the closing, with the existing collective-bargaining agreements expressly preserved.
• Three-year AOC commitment: the buyer must maintain the Portuguese Air Operator Certificate for a minimum of three years, ruling out a fast wind-down or a relicensing under another flag.
• Headquarters in the Açores: the corporate seat stays in the region across the 30-month window, preserving the regional tax and employment footprint.
• Network preservation: the inter-island São Miguel-Terceira link and the connections from those two islands to Lisboa and Porto are explicitly listed as routes that must continue operating, alongside the United States and Canada international links that anchor the diaspora-traffic case for the carrier.

Why a private negotiation and not a tender

The decision to move from a competitive public tender to a private-negotiation framework reflects the March 2026 failure: the previous process did not produce a binding bid inside the European-Commission window, and the Açores executive judged that a curated shortlist with a fixed terms-of-reference document would close faster than a second open tender. The pool of declared interest has been broad — six to eight candidates reported by mid-May, with one Portuguese-led group publicly committing €500 million in capital — and the caderno de encargos is now the document each of them must answer.

The selection criteria the regional government has set out are weighted across four headings: the headline purchase price, the financial-strengthening commitment the buyer attaches to the airline's balance sheet, the viability of the strategic plan for hub development at Ponta Delgada, and the labour-stability guarantees that go beyond the 30-month minimum. Bidders must demonstrate financial capacity, suitability, and the absence of legal or economic constraints — a standard fit-and-proper test that mirrors the framework the Estado is running in parallel on the TAP 49.9% file.

The Augusto Mateus oversight track

Economist Augusto Mateus has been appointed independent supervisor for the negotiation, a role that places him as the technical referee between the regional government and the candidate buyers. His mandate runs across the document-evaluation phase, the negotiation rounds, and the final contract drafting. The supervisor's reports will be public once the winning bid is announced, providing the audit trail the Tribunal de Contas will want to see on a reprivatisation that involves an EU restructuring decision and a regional-budget exposure.

How it sits against the TAP file

The Açores process runs on a parallel-but-separate clock to the TAP SGPS 49.9% privatisation the Estado is closing this summer with three known bidders — Lufthansa, Air France-KLM, and a smaller European combination. Where the TAP caderno reserves 5% of the headline stake for the workforce under a co-investment vehicle and runs a labour-stability narrative that the pilots' union SPAC has already framed as the Lufthansa downside, the SATA caderno bakes labour stability directly into the binding terms with the 30-month no-layoff floor. The two files are sitting on the same political question — how much of the operational footprint stays Portuguese after the sale — but the SATA document answers it with explicit operational covenants rather than a workforce equity slice.

For context on the TAP track, see our coverage of the SPAC pilots' union framing the Lufthansa bid as the labour-stability risk, and on the parallel handling-side dispute that brought cabin-crew and ground unions onto the 3 June general strike call.

What This Means for Expats

• Inter-island flights: the São Miguel-Terceira connection and the Lisboa/Porto continental links are now contractually protected for at least 30 months after closing — so a holiday in the Açores or a property purchase that depends on the air link is not exposed to a quick post-sale network cut.
• Diaspora traffic: the US and Canada international links sit inside the binding routes list, which matters for Portuguese-American and Portuguese-Canadian travellers who route through Ponta Delgada and for residents who fly the seasonal North American services.
• Property values: air connectivity is one of the underwriting inputs for Açores residential and short-stay-rental valuations, and the caderno effectively guarantees baseline connectivity through 2028.
• Employment: the SATA group is one of the largest non-public employers in the Açores; the 30-month no-layoff floor caps the labour-side downside that a typical airline privatisation would otherwise carry.
• Timeline to watch: the Commission's end-of-2026 deadline is the binding date; expect the shortlist of bidders responding to the caderno to firm up over the summer, with a contract award before the autumn budget cycle.
