Defense's Big Day: Structural Rerating or Earnings-Day Pop?

On Thursday the two largest U.S. defense contractors did something the broad market would not. They went straight up. Lockheed Martin (LMT) closed 10.5% higher and RTX (RTX) rose 7.3%, with Honeywell (HON) and GE Vernova (GEV) following, while consumer and communication names dragged the S&P 500 lower. Both primes beat on earnings and raised full-year guidance the same morning. The move was big. What the desk is arguing about is whether it marks a lasting repricing of defense earnings power or a single session that fades once the headlines cool.

The order books swelled faster than sales

Lockheed reported second-quarter earnings of $7.94 per share on sales of $20.1 billion, up 11% from a year earlier, and lifted its 2026 sales outlook to $79.75 to $81.75 billion. The figure that drew the most attention was the backlog. It reached a record $230 billion, up about $64 billion from a year earlier, at a book-to-bill ratio above three to one. The company booked far more new work than it shipped. A $35 billion Missile Defense Agency award to expand THAAD interceptor production anchored the quarter. Much of the demand reflects the Pentagon replenishing munitions drawn down by the wars in Ukraine and Iran, and Lockheed’s missiles and fire-control unit grew 19% to $4.1 billion.

RTX told a similar story from a larger base. Adjusted earnings came in at $1.89 a share on $24.7 billion in revenue, up 14%, and the company raised its 2026 sales guidance to $95 to $96 billion. Its backlog hit a record $289 billion. Behind the surge sits a spending commitment: NATO members agreed this year to move toward 5% of GDP on defense by 2035, and combined alliance budgets topped $1.5 trillion. To supporters, those backlogs are years of visible revenue already under contract, not a forecast.

Valuations already assume the spending arrives

The other side starts with price. Defense stocks entered the week among the market’s more expensive industrial groups, trading at enterprise-value-to-sales multiples well above their historical norms, and 2026 earnings-growth expectations for the group had cooled toward the low teens. When a sector is priced for a long boom, a strong quarter can be the moment holders lock in gains instead of adding to the position.

Then there is the distance between pledges and appropriations. NATO’s 2035 target is a political commitment each member must fund year by year, and European defense shares have gained only in the low single digits in 2026 on doubts about how quickly the money flows. In the U.S., recent authorization debates canceled some programs and underfunded others, a reminder that even a record backlog still depends on budgets Congress passes each year. RTX’s own report carried a wrinkle for the supercycle read: most of its record backlog, $170 billion of the $289 billion, is commercial-aerospace orders tied to the travel recovery, against $119 billion in defense.

What the data shows

Thursday’s session split cleanly. Among large caps, the biggest gainers were defense and aerospace: Lockheed up 10.5%, RTX up 7.3%, Honeywell up 5.7%, GE Vernova up 4.7%. The industrials sector (XLI) led all eleven groups on the day, rising 1.7%, while consumer discretionary fell 4.6% and communication services fell 3.5%. The pattern looked like rotation: growth names down, industrial and defense names up, with the guidance raises giving buyers a fresh reason to move.

What would settle it

The calendar carries the next read. The Federal Reserve announces its rate decision on July 29, with markets pointing to a hold at 3.75%; a steady discount rate keeps the present value of long-dated backlogs intact, while a hawkish surprise would chip at it. Beyond that, three scheduled tests turn the argument into evidence: U.S. defense appropriations for fiscal 2027, NATO members’ required annual spending plans through 2035, and the contractors’ next quarterly reports in October, when investors see whether book-to-bill ratios stay above one. Until contracted work becomes delivered revenue and funded budgets, both readings of Thursday stay open.

The bull case rests on order books the companies can point to today. The skeptical case rests on how much of that future the share prices already hold. Thursday settled the near-term question of demand. It left the harder question, the one about price, for the months of budgets and deliveries ahead.
