Should I invest in Military & Solid IT companies?

Hi everyone. Total noob in stock investment hence this topic. So basically I work for a German IT company that specialises in developing and selling Solid / Rugged IT hardware & software for the Defense / Military sector. Some of the biggest names in these industries are our customers, such as Airbus Defense, Elbit Systems, Boeing, General Dynamics and many more, and also armies of NATO member states directly. As of January 1st we were officially acquired by an even bigger company in the industry which has it‘s subsidiaries in the USA, UK, Europe and Australia respectively. In December on our first meeting with the management of the company that just acquired us we were told that after the takeover process is finished and everything is approved by the German government and the deal is finalised we as employees will be offered to purchase/invest in the stocks of the company. Currently the stocks of the company are trading at 126.50 euros per stock. How good do you people think this offer is? Should I invest? What would be the worst case scenario? Once again, keep in mind that I‘m a total noob in stock investment.
