Simplify's Take

What believers are saying

  • Orange raised 2026 EBITDA guidance above 4% and cash flow to about €4.3 billion.
  • MasOrange became fully consolidated in June 2026, immediately boosting earnings and cash generation.
  • The SFR transaction would add five million subscribers and 47 MHz spectrum by 2027.

What critics are saying

  • French antitrust review of the SFR deal runs into 2027, delaying strategic payoff.
  • Orange France's REGAIN restructuring targets over 20,000 employees, triggering union resistance in 2026.
  • Net debt hit 2.4x after MasOrange; another failed integration would constrain capital flexibility.

What makes Orange unique

  • Orange Business bought Obvios Dome on September 2, 2026, adding sovereign private 5G.
  • Orange launched Wi-Fi 7 repeaters with SoftAtHome in France and Poland during 2026.
  • Orange's Africa, Middle East, and Europe 6 businesses keep outperforming mature European peers.

Orange launches "Reconnexion Flash", using SoftAtHome's Always'ON to keep homes online in fibre outages

SoftAtHome's Always'ON software powers Orange's new "Reconnexion Flash" service in France, the company announced on October 13, 2026. When a fiber line fails, the Livebox automatically routes the home's connection through the customer's smartphone hotspot. No app, VPN, or extra hardware is needed. Laptops, tablets, smart TVs, and other devices stay online over Wi-Fi or Ethernet, and the Livebox switches back to fiber once service returns. Orange activated the service remotely for customers with the Livebox 7 Wi-Fi 7 and Livebox S. Landline phone and multicast TV channels resume only when fiber is restored. "An outage is a sensitive moment when a broadband customer judges their operator," said Arnaud Bellivier de Prin, chief executive officer of SoftAtHome.
