Geopolitics has moved sharply back into focus, with fresh headlines around Ukraine, NATO and rising tensions with Iran reshaping how investors think about risk and opportunity. Shifts in US military support, including a license for Ukraine to produce Patriot missiles, and a firmer tone on European security are feeding into sentiment across global markets. This article looks at 3 stocks from a Defense and Aerospace Sector Stocks screener that appear positively exposed to these developments. It is designed to help you decide whether they deserve a closer look or a place on your watchlist as this story unfolds.

Officina Stellare (BIT:OS)

Overview: Officina Stellare is an Italian aerospace company that designs and builds high precision telescopes and optical systems used in defense, earth observation, astronomical research and space situational awareness. Its equipment supports applications such as adaptive optics, laser communications and other advanced sensing needs for governments, research institutions and commercial customers worldwide.

Operations: Officina Stellare reports revenue primarily from Italy at about €6.9 million, with additional contributions from Europe, the Middle East and Africa excluding Italy at roughly €6.0 million, America at about €2.8 million and the Asia Pacific region at around €1.2 million.

Market Cap: €269.0 million

Officina Stellare sits at the intersection of high end optics and rising defense spending, which makes it particularly interesting against the backdrop of renewed NATO focus and support for Ukraine. Earnings growth has been very strong, with net profit margin moving to 6.2% from 2.1%, and earnings increasing at a rate that exceeds both the Italian market and wider aerospace and defense sector. At the same time, the stock trades below an internally estimated intrinsic value despite a rich P/S multiple. However, high debt, a volatile share price and limited information on board independence point to meaningful risk. For investors tracking how geopolitical realignment might influence specialist contractors, there is more to unpack in Officina Stellare’s numbers and contract exposure.

Officina Stellare’s rapid earnings momentum and high-end optics story could be masking something investors are only starting to notice. Walk through the 3 key rewards and 2 important warning signs (1 is major!) to see what might tilt the balance next.

MDA Space (TSX:MDA)

Overview: MDA Space is a Canadian space technology company that builds satellites, robotics and Earth observation systems used for broadband connectivity, defense surveillance and missions to the Moon and Mars, serving governments, space agencies and commercial customers worldwide.

Operations: MDA Space generates its CA$1.7b in revenue from a combined Geointelligence, Robotics & Space Operations and Satellite System segment, supported by CA$1.1b from Canada, CA$527.1m from the United States and smaller contributions from Europe, Asia and the Middle East.

Market Cap: CA$7.8b

MDA Space sits at the intersection of rising defense budgets, growing demand for secure satellite connectivity and a fresh geopolitical push to strengthen Western space capabilities. Large contracts like the recent RADARSAT+ awards, a CA$688m replenishment satellite deal and the planned acquisition of Blue Canyon Technologies add scale to its satellite and robotics pipeline. The new Montréal facility is intended to support high volume production. At the same time, a very high P/E multiple, falling profit margin from 8.1% to 6% and reliance on external borrowing keep valuation and balance sheet risk firmly on the table. For investors tracking how new defense spending priorities might reshape space infrastructure suppliers, MDA Space’s contract backlog and expansion plans raise important questions that go beyond the headlines.

MDA Space’s expanding contract book and new Montréal facility hint at a company trying to scale faster than many investors realize, yet its high P/E and thinner margins make the 4 key rewards and 1 important warning sign feel like the missing twist in this story.

RADA Electronic Industries (RADA)

Overview: RADA Electronic Industries is an Israeli defense technology company that supplies advanced radars, avionics and recording systems for fighter jets, unmanned aircraft, ground forces and counter drone missions, serving defense customers worldwide.

Market Cap: $490.9m

RADA Electronic Industries sits in the slipstream of rising demand for missile defense and tactical radar, and the renewed US commitment to Ukraine and NATO could keep attention on the kind of sensor systems it supplies. Earnings are forecast to grow quickly and the stock trades below an internal fair value estimate. However, the P/E is high and margins have recently slipped from 19.5% to 5.3%. This makes the outlook more complex than a simple growth story. The company also has high board independence and experienced management, but a funding mix that leans on higher risk external sources. Overall, this is a radar specialist that may warrant a closer look rather than a quick verdict.

RADA Electronic Industries may appear to be a growth story that has stalled on the surface, with a high P/E and margins at 5.3%. However, the real twist sits inside the 2 key rewards and 1 important warning sign
