ULA relies on parent backing to weather Vulcan grounding

ULA’s Vulcan Centaur grounding due to booster nozzle anomalies has prompted its corporate parents to guarantee up to $500 million in borrowings to bolster liquidity, with Lockheed Martin recognizing a $64 million increase in its investment to reflect the guarantee’s fair value. The issues stem from booster anomalies on two Vulcan launches, leaving Vulcan idle since USSF-87 as Northrop Grumman works on redesigned motors, Space Force considers manifest adjustments, and Atlas 5 flights continue while Starliner faces schedule uncertainty. ULA had planned a high launch cadence for 2026 but has a backlogged pipeline of more than 80 missions, and both parents say they may provide further liquidity if needed, though impairment risks exist if Vulcan underperforms.
