1 PRESS RELEASE Important strategic move by Leonardo in the rapidly growing force protection market: Leonardo DRS and RADA agree to an all-stock merger  Leonardo is strengthening its leadership position in the rapidly growing force protection market  Leonardo has recently focused the portfolio of DRS through the previously announced entry into agreements to divest GES and AAC and is now, with RADA, making a significant strategic step forward, reinforcing the company around its core business of sensors and integrated systems, resulting in higher growth and further margin expansion  The combination is an excellent fit strategically, commercially and financially  The transaction also seizes the opportunity of listing Leonardo DRS in the current context of highly volatile markets, thus delivering on promises Rome, 21/06/2022 – Leonardo announced today that its US subsidiary Leonardo DRS and RADA Electronic Industries Ltd. have entered into a definitive agreement to create a newly combined public company. RADA Electronic Industries Ltd. (NASDAQ: RADA, TASE: RADA) (“RADA”) is a leading provider of advanced software-defined military tactical radars. The company is a leader in mini-tactical radars, serving attractive, high-growth markets, including critical infrastructure protection, border surveillance, active military protection and counter-drone applications. RADA is listed on the NASDAQ and Tel Aviv stock exchanges. Alessandro Profumo, Leonardo CEO, stated: “We are delighted to announce this important strategic move by Leonardo in the rapidly growing force protection market, which is at the core of today’s and tomorrow’s defence market. There is an excellent fit between our US subsidiary Leonardo DRS and RADA: strategically, commercially and financially. As promised, we have focused the Leonardo DRS portfolio and we are now reinforcing DRS with RADA in core strategic businesses, providing growth, further margin expansion and opportunities in the wider Leonardo Group. We have agreed to an all- stock merger transaction, also seizing the opportunity of listing DRS in the current context of volatile markets, thus delivering on what we promised last year.” In recent years, Leonardo has successfully reinforced Leonardo DRS competitive positioning, delivering on promises, focusing it on its core business, through the previously announced disposition of GES and AAC and now making a significant strategic step forward, with the combination with Rada, adding a strong business in active defense solutions. Leonardo DRS and RADA combined are expected to generate strong growth fueled by their competitive product suite addressing the core needs of their customers. "The combination of RADA’s tactical radar capabilities and Leonardo DRS’ strength as a premier mid- tier defense provider make the combined company a leader in the rapidly growing force protection market, increases our addressable market, expands international opportunities and ultimately unlocks value for shareholders,” said William J. Lynn III, CEO of Leonardo DRS.

2 RADA is also an excellent fit within Leonardo Group, as it provides an enhanced value proposition with its advanced tactical radars complementary to Leonardo’s sensor portfolio, enabling a stronger position and integrated approach in emerging sectors in the tactical operating environment. It also adds a domestic presence in Israel and supports the development of the international market for Leonardo, and at the same time allowing RADA to access opportunities in European and export markets and programmes, leveraging Leonardo’s global presence. Leonardo DRS will acquire 100% of the share capital of RADA in exchange for 19.5% equity ownership to RADA shareholders in Leonardo DRS, with Leonardo maintaining 80.5% in Leonardo DRS through its US subsidiary Leonardo US Holding (subject to approval of the stockholders of RADA and other closing conditions including the receipt of certain regulatory approvals). Upon closing of the transaction, expected in the fourth quarter of 2022, Leonardo DRS is expected to be listed on NASDAQ and TASE under the new ticker symbol “DRS.” Advisors Evercore is serving as financial advisor to RADA and J.P. Morgan Securities LLC is serving as financial advisor to Leonardo DRS.
