Boeing reported fourth-quarter 2025 results Monday that showed the clearest signs yet of a genuine turnaround at the embattled aerospace giant. For the first time since 2018—before the 737 MAX crashes, the pandemic, and the quality scandals that nearly destroyed the company—Boeing generated meaningful positive free cash flow and projected that 2026 will produce $1-3 billion in cash.

The Numbers

Boeing's fourth-quarter results showed improvement across key metrics:

  • Revenue: $23.95 billion, up 57% year-over-year, beating estimates of $22.17 billion
  • GAAP EPS: $10.23, including a $9.6 billion gain from selling the Digital Aviation Solutions business
  • Operating cash flow: $1.3 billion positive
  • Free cash flow: $400 million positive in Q4
  • Commercial deliveries: 117 in Q4, 600 for full-year 2025—the highest since 2018

Full-year 2025 revenue reached $89.5 billion, also the highest since 2018. While the company still burned $1.9 billion in free cash flow for the full year, the positive Q3 and Q4 results suggest the trajectory has finally inflected.

"We've set the foundation for our turnaround with stronger performance and record backlogs across commercial, defense, and services. We haven't fully turned the corner, but we're making real progress."

— Kelly Ortberg, Boeing CEO

The 2026 Outlook

Boeing guided for 2026 free cash flow between $1 billion and $3 billion—the first time the company has projected meaningful positive cash generation in years. CFO Jay Malave called this "pretty substantial growth year-over-year."

The guidance includes an approximately $1 billion headwind from integrating Spirit AeroSystems, the supplier Boeing is bringing back in-house after quality problems exposed the risks of outsourcing critical manufacturing.

Key assumptions underlying the guidance:

  • 737 MAX production: Ramping to 47 per month later in 2026
  • 787 Dreamliner: Stable production at 5 per month
  • Defense programs: Continued execution on fixed-price contracts that have caused losses
  • No major disruptions: Labor peace, supply chain stability, and no new quality escapes

Ortberg's Factory-Floor Focus

CEO Kelly Ortberg, who took the helm in August 2024, has been credited with changing Boeing's culture. Unlike his predecessors who emphasized financial engineering and Chicago headquarters management, Ortberg relocated to Seattle to be closer to manufacturing operations.

His approach has been straightforward: fix the factories first, and the financial results will follow. That philosophy appears to be working:

  • Quality improvements: Fewer defects are escaping production lines
  • Production stability: More consistent output enabling better planning
  • Employee morale: Workers report improved conditions and clearer priorities

"Kelly Ortberg has been praised for his 'factory-floor' focus," analysts noted. "He famously relocated near Boeing's manufacturing hub to stay closer to production reality—a symbolic and practical shift from previous leadership."

FAA Production Cap Lifted

The results benefited from the FAA lifting its strict 38-per-month production cap on the 737 MAX. That cap, imposed after a January 2024 door-plug blowout on an Alaska Airlines flight, had constrained Boeing's ability to generate revenue and cash.

With the cap lifted, Boeing can now produce up to 42 MAX aircraft per month, with approval to reach 47 later in 2026. Each additional aircraft represents roughly $50-70 million in revenue and meaningful profit contribution.

Record Backlog Provides Visibility

Boeing ended 2025 with a record $682 billion backlog—or $692 billion by some measures—providing years of production visibility:

  • Commercial Airplanes: $539 billion backlog, approximately 5,600 aircraft
  • Defense, Space and Security: $74 billion backlog
  • Global Services: $25 billion backlog

The commercial backlog represents roughly seven years of production at current rates. Airlines are desperate for fuel-efficient aircraft, and Boeing—despite its problems—remains one of only two companies capable of building large commercial jets.

Challenges Remain

The turnaround is far from complete. Boeing faces several ongoing challenges:

Defense Losses

Fixed-price development contracts for programs like Air Force One refurbishment and the KC-46 tanker continue to generate losses. These contracts, signed before cost inflation and supply chain disruptions, will pressure margins for years.

Spirit AeroSystems Integration

Bringing Spirit back in-house addresses quality concerns but adds complexity. The integration will consume cash and management attention through 2026 and possibly beyond.

Debt Load

Boeing ended 2025 with $54.1 billion in debt. While the Jeppesen sale boosted cash reserves to nearly $30 billion, the balance sheet remains stretched. Generating consistent free cash flow is essential to reducing leverage.

Competition

Airbus has gained market share during Boeing's troubles and continues executing well. Chinese competitor COMAC is expanding its capabilities. Boeing's window to regain momentum isn't unlimited.

Stock Reaction

Boeing shares initially swung both directions as investors digested the results, ultimately settling modestly higher. The stock has rallied 22% since early December when CFO Malave first reaffirmed the path to positive cash flow.

At current levels, Boeing trades at a significant discount to its pre-crisis highs but at a premium to crisis lows. The valuation reflects optimism about the turnaround tempered by recognition that execution risks remain substantial.

Investment Implications

Boeing's results suggest the turnaround thesis is playing out, but patience is still required:

  • Bulls argue: The worst is over, cash generation will ramp, and the stock has significant upside as confidence returns
  • Bears counter: Execution risks persist, the balance sheet is stressed, and competition has intensified

The $1-3 billion free cash flow guidance, if achieved, would represent a dramatic improvement from years of burning cash. But the wide range reflects genuine uncertainty about how smoothly production will ramp.

For long-term investors who believe in the duopoly nature of commercial aviation, Boeing at current levels may offer attractive risk-reward. For those demanding certainty, the company needs several more quarters of consistent execution before the turnaround can be considered complete.

Looking Ahead

Boeing's path forward depends on disciplined execution: ramping production without quality escapes, managing supply chains, and containing defense program losses. Ortberg has set the right priorities; now the company must deliver.

"To continue our turnaround, we still have important work ahead of us—perhaps even more than what we accomplished last year," Ortberg wrote in a recent employee memo. That honesty, combined with the first positive cash results in years, suggests a leader who understands both how far the company has come and how far it still has to go.
