S&P Downgrades Thames Water to CCC- on Debt Extension and Distress

Thames Water's Financial Struggles and S&P Downgrade

Oct 27 (Reuters) - Global ratings agency S&P downgraded Thames Water Utilities by a notch to "CCC-" on Tuesday, saying the UK water supplier's plans to extend debt maturities and increase borrowing under a super senior facility reflected a distressed financial position.

Key Details of the Downgrade

Here are some details:

Emergency Funding and Debt Extension

• Earlier this month, Thames Water said it needed to increase its emergency funding facility by £2.4 billion, to keep operating into autumn 2027

Debt Restructuring and Liquidity Concerns

• S&P said the move comes amid a prolonged debt restructuring and weak liquidity against a sizable capital expenditure program and recurrent negative free operating cash flows

Further Downgrades and Ratings Impact

• The agency also lowered Thames Water Utilities Finance's rating to "CCC-" from "CCC"

Debt Burden and Infrastructure Issues

• The utility, saddled with about £20 billion in debt, has been fighting for survival after years of inadequate investment in its ageing infrastructure

Outlook and Default Risks

• S&P held a "negative" outlook on Thames, suggesting that it could view an increase in super senior debt and a near-term extension of debt maturities without adequate compensation to creditors as a default

Key Takeaways

  • S&P lowered both Thames Water Utilities and its Finance subsidiary to CCC– with a negative outlook, warning of possible default if compensation to creditors remains inadequate and restructuring drags on using low‑priority super‑senior debt.
  • The company is seeking a £2.4 billion increase in its super‑senior facility to £5.4 billion to maintain operations into autumn 2027, after drawing £2.65 billion of the existing facility, and faces a looming vote by creditors on October 29, 2026.
  • Thames Water holds about £20 billion in debt, with weak liquidity, suspended financial covenants, and sustained negative free cash flows, underscoring its capital‑intensive operations and fragile gearing amid the AMP8 capital programme.
