Lockheed Martin (LMT) just combined a strong fourth quarter, a higher 2026 outlook for sales and profit, and major interceptor production agreements into one dense batch of information for investors.

The 26.4% year to date share price return, including a 26.4% 1 month share price return and 32.8% 3 month share price return, suggests strong momentum. The 42.6% 1 year total shareholder return and 110.6% 5 year total shareholder return indicate that recent enthusiasm builds on longer term gains.

If this aerospace and defense story has your attention, it could be a useful moment to see what else is on the radar across aerospace and defense stocks.

Fast-rising earnings guidance, record backlog and interceptor orders, and a share price now sitting just below the latest analyst targets raise a key question: Is Lockheed Martin still mispriced, or is the market already banking on future growth?

Most Popular Narrative: 10.3% Overvalued

Compared with the narrative fair value of $569.68, Lockheed Martin's last close at $628.26 sits above that mark, which is where the tension in this story starts.

The growing focus on homeland defense initiatives such as "Golden Dome," missile warning networks, and increased munitions spending suggests future secular increases in U.S. defense budgets and multi-year, high-value contract awards that are likely to contribute meaningfully to backlog, revenue visibility, and cash flow stability.

Want to see what kind of revenue path and profit profile those contracts are expected to build in, and how that feeds into a richer earnings multiple and higher fair value over time, without relying on any single headline program? The full narrative lays out that financial blueprint in detail.

Result: Fair Value of $569.68 (OVERVALUED)

However, there is still real risk that large fixed price program charges or a US$4.6b tax dispute outcome could unsettle earnings expectations and confidence in the current setup.

Another View: Earnings Multiple Says “Good Value”

While the SWS narrative fair value marks Lockheed Martin as 10.3% overvalued, its P/E of 28.8x sits well below the US Aerospace & Defense average of 40.7x, the peer average of 36.6x, and a fair ratio of 35.9x. This points to valuation support instead of excess. With those gaps in mind, is the market underestimating the risk in the story or the potential reward if sentiment shifts?
