Here are some industries and companies have historically experienced a spike in activity during times of war:
Defense Contractors: Businesses that produce military hardware, weaponry, and technology frequently experience a spike in demand during times of conflict. Northrop Grumman, Raytheon Technologies, Boeing, Lockheed Martin, and General Dynamics are a few examples.
Security and Private Military Contractors: During times of conflict, companies that offer logistics, security, and support to military operations may enjoy an increase in contract work. Businesses in this sector include G4S, DynCorp International, and Blackwater (now known as Academi).
Energy companies: Increasing demand or volatility in oil-producing regions can be advantageous to oil and gas corporations. It's important to remember, too, that while some businesses can see short-term success, protracted hostilities can cause supply networks and investments in these areas to collapse. There may be an influence on businesses like BP, Chevron, and ExxonMobil.
Infrastructure and Reconstruction: Businesses that work in war-torn areas to develop, build, and reconstruct infrastructure may be awarded contracts for reconstruction projects. There may be more activity from engineering firms, construction companies, and logistical suppliers.
Aerospace and Aviation: In addition to defense contractors, airlines and aerospace firms stand to gain from heightened military activity and the necessity for transportation in times of warfare.
Technology and Cybersecurity: Governments and commercial organizations looking to safeguard vital infrastructure and data may place a greater demand on businesses providing cybersecurity solutions if conflicts spill over into cyberspace.
