Saudi Arabia has a pending deal to acquire $500 million in precision-guided munitions from the U.S., part of a proposed $110 billion arms package to Riyadh, which is enmeshed in a civil war in Yemen.

The acquisition of Orbital would strengthen Northrop Grumman's capabilities in military aircraft technology and missile defense. Orbital ATK makes launch vehicles and their propulsion systems, missile technology, defense electronics, precision weapons, armament systems and ammunition.

Orbital ATK shareholders will receive $134.50 per share, a 22 percent premium to the company's Friday closing price of $110.04. The deal's total value is approximately $9.2 billion, including debt.
Shares of Orbital ATK surged 20 percent in Monday premarket trading, to around $132. It appears the company will join most major defense contractors that have seen shares hit all-time highs this year as clashes escalate.
