The Boeing Company’s (BA Quick QuoteBA - Free Report) shares have lost 3.2% over the past three months compared with the Zacks Aerospace-Defense industry’s decline of 3.8%. Boeing remains one of the largest U.S. commercial aircraft manufacturers. Steadily growing commercial air travel should boost Boeing’s service business unit. The outlook for Boeing’s defense and space business segment also remains optimistic.

Shares of other defense stocks, such as Northrop Grumman (NOC Quick QuoteNOC - Free Report) and Lockheed Martin (LMT Quick QuoteLMT - Free Report) , have shown mixed performance over the same time frame. Shares of Northrop Grumman have lost 3.1% while those of Lockheed Martin have risen 2.7%. Northrop Grumman benefits from a record backlog, rising defense spending and expanding demand for strategic deterrence, missile defense, space and advanced aircraft. Lockheed Martin’s record backlog, expanding munitions capacity and alignment with U.S. and allied defense priorities support durable growth. 

Considering Boeing’s current price decline, investors may be wondering whether now is a good time to add the stock to their portfolios. Let’s examine the factors and assess the company’s investment prospects to make a more informed decision.

Factors Acting in Favor of BA Stock

The outlook for the aerospace giant’s defense and space business also remains encouraging, as Boeing is one of the largest defense contractors globally and a prominent integrator for the International Space Station.

Thanks to its diverse defense product portfolio and established footprint in the space technology industry, Boeing witnesses a solid inflow of contracts. In the second quarter of 2026, Boeing’s Defense, Space & Security (“BDS”) revenues increased 13% year over year to $7.48 billion, driven by higher volumes across classified programs, missiles and weapons, and KC-46A activity. The segment booked $7 billion of orders and ended the quarter with an $85 billion backlog, with 27% tied to customers outside the United States.

Recently, Boeing completed the sale of its 50% stake in HRL Laboratories (which was a 50/50 joint venture between Boeing and GM) to IBM. The completion benefits Boeing by allowing the company to focus capital and management resources on its core aerospace, defense and space businesses, rather than allocating resources to an advanced-technology joint venture outside its primary operations.

Boeing’s new seven-year framework agreements for the Standard Missile-3 (SM-3) provide a positive growth opportunity for the BDS segment by giving the company greater visibility into long-term demand for critical missile-defense components. Under the agreements, Boeing will increase production of avionics and ejector assemblies used in the SM-3 Block IB and IIA interceptors, which are key part of U.S. and allied sea-based missile defense.

Key Headwinds Facing BA Stock

The order book is growing, but slow production, delayed deliveries and ongoing inspections could be turning customers away from Boeing’s commercial airplanes, leading to recent order cancellations. Aircraft order cancellations during the six months ended June 30, 2026, totaled $2.78 billion and were primarily related to 737 aircraft. The 777X program has suffered repeated postponements and significant cost overruns. 

The Boeing 777X program is running seven years late, with an expected entry-into-service date in 2027. These delays, caused by rigorous FAA scrutiny, design changes and part cracks, have resulted in significant cost overruns. The ongoing trade tensions between the United States and China pose another challenge. Any escalation in trade disputes could delay these deliveries, hurting revenues and increasing inventory costs.

The Zacks Consensus Estimate for Boeing’s 2026 earnings per share (EPS) indicates a year-over-year improvement of 91.82%.

BA Stock’s Liquidity

The company’s current ratio is 1.14 compared with the industry’s average of 1.10. A ratio of more than one suggests a healthy liquidity position, where the business can meet its immediate financial obligations without selling long-term assets.

BA Stock Trades at a Discount

In terms of valuation, Boeing’s forward 12-month price-to-sales (P/S) is 1.55X, a discount to the industry’s average of 2.36X. This suggests that investors will be paying a lower price than the company's expected sales growth compared with that of its peer group.

What Should Be the Next Move?

Boeing’s BDS business remains well positioned for growth, supported by a diversified defense portfolio, strong contract activity and an established presence in space technology. Recent strategic actions further strengthen its focus on core defense programs and provide greater long-term revenue visibility.

Considering current execution challenges, new investors should wait and look for a better entry point. Investors who already own this Zacks Rank #3 (Hold) stock may consider retaining it, given the company’s strong earnings growth and solid liquidity.
