SES S.A. (SESG.PA): The Undervalued Space Infrastructure Play for 2026

SES S.A. is a leading satellite operator with a unique position in the space economy, operating both geostationary (GEO) and medium Earth orbit (MEO) constellations. Despite the sector’s growth, SES trades at a significant discount to its peers, offering a compelling risk/reward for investors seeking exposure to space infrastructure with tangible cash flows.

Investment Thesis

SES is undergoing a strategic transformation, focusing on high-growth areas like government services and network connectivity, while rationalizing its legacy video business. The company’s MEO constellation, O3b mPOWER, is now fully operational, providing a competitive edge in low-latency, high-throughput connectivity. With a strong balance sheet and a clear path to debt reduction, SES is positioned to generate significant free cash flow, which could support shareholder returns and a potential rerating.

Catalysts

  • Continued ramp of O3b mPOWER services, driving revenue growth in the Networks segment.
  • Potential contract wins in government and defense, leveraging secure satellite communications.
  • Further deleveraging and potential resumption of dividend growth or share buybacks.
  • Possible strategic partnerships or consolidation in the satellite industry.

Key Risks

  • Intense competition from new LEO constellations (e.g., Starlink) could pressure pricing and market share.
  • Legacy video business decline may be faster than expected, impacting overall revenue.

Valuation

SES trades at a significant discount to its historical average and to peers, with an EV/EBITDA multiple in the mid-single digits. The market is pricing in a secular decline, but the company’s transformation and cash flow generation are not fully reflected. As the market recognizes the stability of its cash flows and the growth potential of its networks business, a re-rating is plausible.

Balance Sheet

SES has a manageable debt load, with a net debt to EBITDA ratio around 2.5x. The company has been consistently generating strong free cash flow, which is being used to reduce leverage. This financial discipline provides a margin of safety for investors.
