As the craze of earnings season draws to a close, here’s a look back at some of the most exciting (and some less so) results from Q1. Today, we are looking at defense contractors stocks, starting with Mercury Systems (NASDAQ: MRCY).

Defense contractors typically require technical expertise and government clearance. Companies in this sector can also enjoy long-term contracts with government bodies, leading to more predictable revenues. Combined, these factors create high barriers to entry and can lead to limited competition. Lately, geopolitical tensions–whether it be Russia’s invasion of Ukraine or China’s aggression towards Taiwan–highlight the need for defense spending. On the other hand, demand for these products can ebb and flow with defense budgets and even who is president, as different administrations can have vastly different ideas of how to allocate federal funds.

The 14 defense contractors stocks we track reported a strong Q1. As a group, revenues beat analysts’ consensus estimates by 2.5% while next quarter’s revenue guidance was in line.

Luckily, defense contractors stocks have performed well with share prices up 17.1% on average since the latest earnings results.

Market Update

Thanks to the Fed’s series of rate hikes in 2022 and 2023, inflation has cooled significantly from its post-pandemic highs, drawing closer to the 2% goal. This disinflation has occurred without severely impacting economic growth, suggesting the success of a soft landing. The stock market thrived in 2024, spurred by recent rate cuts (0.5% in September and 0.25% in November), and a notable surge followed Donald Trump’s presidential election win in November, propelling indices to historic highs. Nonetheless, the outlook for 2025 remains clouded by potential trade policy changes and corporate tax discussions, which could impact business confidence and growth. The path forward holds both optimism and caution as new policies take shape.
