Looking back on defense contractors stocks’ Q4 earnings, we examine this quarter’s best and worst performers, including Parsons (NYSE:PSN) and its peers.
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 mixed Q4. As a group, revenues beat analysts’ consensus estimates by 2.6% while next quarter’s revenue guidance was 4.3% above.
In light of this news, share prices of the companies have held steady. On average, they are relatively unchanged since the latest earnings results.

Market Update
As a result of the Fed’s rate hikes in 2022 and 2023, inflation has come down from frothy levels post-pandemic. The general rise in the price of goods and services is trending towards the Fed’s 2% goal as of late, which is good news. The higher rates that fought inflation also didn't slow economic activity enough to catalyze a recession. So far, soft landing. This, combined with recent rate cuts (half a percent in September 2024 and a quarter percent in November 2024) have led to strong stock market performance in 2024. The icing on the cake for 2024 returns was Donald Trump’s victory in the U.S. Presidential Election in early November, sending major indices to all-time highs in the week following the election. Still, debates around the health of the economy and the impact of potential tariffs and corporate tax cuts remain, leaving much uncertainty around 2025.
