Kosmos Energy (KOS) Q2-25 10-Q highlights
- Revenue deterioration: Q2 sales fell 13% YoY to $392.6 M; H1 revenue down 22% to $682.8 M, hurt by lower liftings and weaker Brent pricing.
- Earnings swing: Net loss of $87.7 M (-$0.18/sh) versus $59.8 M profit last year; H1 loss $198.3 M (-$0.42/sh). Gross production costs nearly doubled YoY to $243.1 M while DD&A rose 68% to $151.3 M.
- Cash squeeze: Operating cash flow collapsed to $126.3 M in H1 (vs $496.2 M); cash balance down to $51.7 M from $85.0 M at year-end.
- Leverage: Total debt enlarged to $2.90 B (+$100 M); current maturities $250 M due within 12 months. Net debt/EBITDAX exceeded covenant; lenders waived restricted-cash requirement and loosened the debt-cover ratio to 4.25× through Mar-26.
- Asset progress: Greater Tortue Ahmeyim (GTA) Phase 1 achieved commercial operations in Jun-25, triggering first LNG revenue and increasing long-term receivables from national oil companies to $444.7 M.
- Capex & hedging: H1 capex trimmed to $172.8 M (prior-year $553.0 M). ~8 MMbbl of 2025-26 production hedged with collars/swaps (floors $50-60/bbl).
- Equity impact: Book value slid 15% YTD to $1.02 B as accumulated deficit widened.
Outlook: Near-term liquidity rests on GTA cash inflow, Jubilee infill drilling and maintenance of covenant headroom. High debt load, rising operating costs and volatile oil prices remain key risks.
