Thank you, and good morning. Welcome to Boeing's quarterly earnings call. With me today are Kelly Ortberg, Boeing's President and Chief Executive Officer, and Jay Malave, Boeing's Executive Vice President and Chief Financial Officer. This quarter's webcast, earnings release, and presentation, which include relevant disclosures and non-GAAP reconciliations, are available on our website. Today's discussion includes forward-looking statements that are subject to risks and uncertainties, including the ones described in our SEC filings. As always, we'll leave time at the end of the call for analyst questions. With that, I will turn the call over to Kelly Ortberg.
Thanks, Eric, and good morning, everyone. Thanks for joining in today's call. Before we get started, I want to express our sincere condolences to the families and loved ones of the eight dedicated aircrew whose lives were lost in the U.S. Air Force B-52 accident in June. Our hearts remain heavy for the lives lost, including two incredible Boeing colleagues who worked side by side with our customer on the program. We continue to provide technical assistance to the investigation, and we're supporting the Air Force in every way we can. Now let's shift our focus to the second quarter. We're halfway through the year, and I'm very pleased with our progress as we execute on our 2026 plan. With the continued focus on safety and quality, our teams are increasing production and delivering at levels we have not seen since 2018.
Our commercial certification programs, a key focus for us this year, remain on plan, and I'm proud of our team's dedication to complete the certification work, as well as how we have continued to work collaboratively with our regulators. Earlier this month, the FAA authorized Boeing to resume issuing airworthiness certificates for all 737 MAX and 787 airplanes. We worked hard to build this trust from the FAA, and we take this responsibility very seriously. Safety will continue to lead the way in everything we do. In defense and space, we continue to address risks in the portfolio while increasing output to meet today's mission and invest in the capabilities for our future fight. Our Service business has seen robust growth despite macro uncertainty, and we continue to win favor with our customers every day.
We are strengthening the trust with our supply chain through increased transparency and strong demonstrated performance. This positions us to deliver higher volumes and respond quickly when challenges arise. All of this progress is set against a backdrop of a record backlog and culture change that continues to take hold and improve the way we work together. We know there's more work to do and remain clear-eyed about managing the risks in front of us. The momentum that we've built in the first half of this year is setting us up for more dependable performance as we execute the second half. Let's now take a closer look at our businesses, and we'll start with commercial airplanes. As we've said all year long, completing the certification work on our development programs is one of our biggest goals. We continue to make a lot of progress consistent with our plans.
In fact, on 737-7, testing is done, and we expect to receive an amended type cert from the FAA very soon. On 737-10, we recently completed our final test flight and expect certification following the 737-7. These certifications pave the way for both airplane variants to start deliveries in 2027, and I'm confident these newest members of the 737 MAX family will deliver on the promise of greater efficiency and more capability for our customers. On the 777-9, we remain on plan for first delivery in 2027. In June, we received approval from the FAA for the next phase of the certification flight test called TIA 4B. This unlocked the largest remaining portion of the flight testing, and we've currently completed more than 55% of the certification flight testing and expect our accelerated pace to continue progressing this summer.
In addition to certification flight testing under the phased TIAs, we expect approval to start ETOPS testing later this year. Turning now to the BCA production programs. On 737, we're now ramping to 47 airplanes per month after a successful capstone review in May and expect factory rollouts to reach 47 per month this summer. Just as with our previous rate breaks on the program, we're closely monitoring our key performance indicators in the factory, and so far, early results are within our expectations, driven by the fundamental improvements we made to factory health. In Wichita, our integration is going well as teams continue to meet targeted reduction in quality defects before shipping fuselages to the final assembly. Earlier this month, we began low-rate MAX production on our North Line, which enables us to reach our next planned rate break of 52 per month.
I was with the team in Everett just after the first fuselage loaded into our new production line, and I can tell you they are ready and energized to build 737s. Our Everett team will be guided by the same safety and quality plan that has been successful in Renton, and the low-rate production will include certification of that new line. In Charleston, on the 787 program, we've now stabilized at eight airplanes per month. We did take the decision to temporarily slow production systems for several days in April to allow portions of the supply chain to recover. As we've said before, we're guided by our safety and quality plan and will only move production forward when the system and our supply chain are ready. We'll continue to work with GE on the engine delivery recovery this summer, which will be important for our rate 10 timing.
Across the commercial market, we continue to see exceptional demand and market conditions as evidenced by our record backlog of more than 6,200 airplanes and a market outlook of nearly 44,000 new aircraft over the next 20 years. Let's now shift to BDS, where we're making progress and staying focused on disciplined execution to strengthen performance, meeting customer commitments, and making deliberate investments in our programs. During the quarter, we achieved Milestone C for both the T-7 and the MQ-25 programs, securing approval to begin low-rate initial production. For the T-7, as an outcome of our active management efforts, we're delivering a production-ready configuration that further reduces risks and accelerates future deliveries.
We also recently reached a memorandum of agreement with the U.S. Air Force, which strengthens KC-46A mission readiness and allows us to partner on the Remote Vision System 2.0 retrofit to get these capability upgrades faster into the full fleet. In fact, we recently completed a very successful first phase of flight testing on the RVS 2.0 upgrade. One of our fixed-price development programs where we have seen cost growth is the VC-25B. As we disclosed this morning, we've made the decision to add significant resources to support the build and test schedule on VC-25B. We have also aligned with the Air Force on moving from an FAA to a military certification basis. These additional resources will also help mitigate potential risks during certification and flight tests. Since this program is in a reach-forward loss, these additional investments resulted in a $280 million charge during the quarter.
Now, while the charge is disappointing, we recognize how critical schedule performance is to our customer, and we are investing accordingly to maintain our commitment to deliver this airplane in 2028. This shouldn't overshadow all the meaningful progress we're making to reduce the risk across our defense portfolio, and we are in much better shape than we were two years ago. Like in our commercial business, the demand signal on our Defense & Space products remains very strong, with notable increased demand in missiles and munitions and secure communications satellites programs. We continue to do a good job in improving our underwriting of new contracts and being selective on the programs we bid. Finally, in BGS, where our service team continues to deliver strong results against the backdrop of a robust aftermarket.
So far, we have not seen a material impact in the Commercial Service business from the conflict in the Middle East, and the Government Service business has seen incremental demand to support ongoing operations. In closing, the momentum we're seeing across these three businesses reflect the steady work our teams are doing every day to strengthen safety, quality, and stability. I want to thank all of our employees for elevating our performance and helping deliver another improving quarter. As you may know, we've been in early contract negotiations with our Puget Sound Engineering Union, SPEEA, ahead of the current contract expiration this October. We began these discussions early because we wanted to work towards an agreement that supports our employees and their families, creates greater clarity for our business, and helps us stay focused on the progress we're making.
So far, the tone of those talks have been respectful and productive. Looking ahead, I'm encouraged by the broader momentum we are building across Boeing as we move into the second half of the year. We had a great Farnborough Airshow last week. Customers and suppliers I spoke with have renewed confidence in our team, products, and ability to deliver on time with higher quality. The work we've done together over the last two years is making a difference, and our team is ready to meet the rising expectations. We have a stronger foundation to build upon. Our operations are more stable, and we're ramping up production to deliver on our record $715 billion backlog. We're on track to be free cash flow positive for the year, and most importantly, we're building trust with all of our stakeholders.
Now I will turn the call over to Jay for our second quarter results in more detail before we take on the questions.
Thanks, Kelly, and good morning, everyone. Starting with consolidated financial results for the quarter. Revenue of $24.6 billion was up 8%, driven by solid growth across all three segments, including higher commercial deliveries and strong defense volume. The revenue impacts from the Spirit acquisition and Digital Aviation Solutions divestiture in 2025 largely offset each other. Operating margin increased to 0.6%. Core earnings per share improved to a loss of $0.76, primarily reflecting higher segment earnings and lower corporate expense, partially offset by the VC-25B program loss. Free cash flow was +$631 million, higher than expectations I shared last quarter based on favorable receipt timing. Compared to prior year, free cash flow improved due to higher commercial deliveries and customer receipts, partially offset by planned CapEx increases as we continue to make progress on our growth investments in St. Louis and Charleston. Turning to BCA on the next page.
BCA again made solid progress in its production performance by delivering 171 airplanes in the quarter, the highest quarterly total since 2018. Revenue of $11.8 billion was up 8% on the higher deliveries and favorable mix. Operating margin of -2.7% improved compared to last year, primarily driven by increased delivery volume and mix. In the quarter, we also recognized other favorable adjustments of about 150 basis points. Excluding those adjustments, profitability improvement was in line with our expectations. Backlog continued to grow and remains at a record level of $597 billion, including over 6,200 airplanes. Clicking down on commercial program performance and starting with the 737. We delivered 129 airplanes in the quarter and remain on track to deliver 500 airplanes this year.
Kelly highlighted the certification progress we have made on the 737-10. We will continue to ramp up 737-10 production in the second half of the year. Turning to the 787, we delivered 25 airplanes, including 13 in June. We remain on track to deliver 90-100 airplanes this year. As Kelly mentioned, during the quarter, we stabilized production at eight per month. At the end of the quarter, we also made important progress on seat certification. In June, Riyadh Air took delivery of its first 787 Dreamliners, airplanes that were previously built but awaiting seat certification. Finally, on 777X, we continue to make steady progress on certification, as Kelly noted. We remain on track for first delivery in 2027. Regarding the previously discussed engine durability issue, GE is finalizing the modifications with the FAA and remains confident in their root cause analysis and solution.
They have already incorporated the change into their production system. Engine deliveries are expected to resume in the third quarter. We continue to manage the entire production system for increased rates. Supply chain readiness, including engines, remains a key factor in our production and delivery plans next year. Shifting over to BDS on the next page. BDS delivered 35 aircraft in the quarter. Revenue increased 13% to $7.5 billion, primarily driven by higher volume, including growth on classified programs, missiles and weapons, and KC-46A tanker. Spirit contributed approximately $130 million to sales in the quarter or about 2 points of growth. Operating margin was -2.2%, which reflects the $280 million loss on the VC-25B program. BDS booked $7 billion in orders during the quarter. Backlog remains strong at $85 billion.
Excluding the impact of the VC-25B adjustment, BDS operating margin was 3.5% in the quarter, reflecting better operating performance across the rest of the business. In line with our expectations for steady margin improvement. Further progress will come from completing fixed-price development programs that currently dilute margins. From executing our sizable backlog, which carries attractive margins that will accelerate improvement. I'm confident that the BDS team is on the right track. We remain confident in the path to return to high single-digit operating margins by the end of the decade. Now, moving to Global Services on the next page. BGS continued to perform well. Again delivered strong financial results in the quarter. Revenue was up 1% to $5.3 billion. Excluding the impact of Digital Aviation Solutions divestiture, revenue was up 8% year-over-year.
Operating margin of 18.1% was down from the prior year, primarily related to the impacts of the Digital Aviation Solutions divestiture, as well as higher costs and less favorable mix. Both commercial and government businesses delivered double-digit margins in the quarter. Operationally, the BGS team continues to drive process improvement across the business. For example, on the P-8 modification program in Jacksonville, we have reduced flow time by 44%, demonstrating the impact of our process and training initiatives. BGS received $5 billion of orders. Ended the quarter with a backlog of $33 billion. Shifting over to cash and debt. Cash and marketable securities ended at $20 billion, primarily reflecting debt repayments, partially offset by cash flow generated in the quarter.
The debt balance ended at $45.9 billion, down $1.3 billion in the quarter and $8.2 billion year-to-date on the paydown of maturing debt, consistent with our debt reduction plans. We also maintained access to credit facilities of $10 billion, all of which remain undrawn, and we remain committed to strengthening the balance sheet and supporting our investment-grade rating. Regarding free cash flow, we remain on track to achieve our outlook of $1 billion-$3 billion. First-half performance came in better than expected, driven by favorable receipt timing within the year. Note that the $700 million DOJ payment planned for the second half of 2026 is expected to be paid in the third quarter. Factoring in that impact, we expect third quarter free cash flow to be positive and in the low hundreds of millions of dollars.
Overall, the improved cash profile gives us confidence in the outlook for the year. Beyond 2026, and consistent with what we have discussed previously, free cash flow is expected to grow, primarily driven by higher commercial deliveries, steady improvements at BDS, and continued growth at BGS. We continue to view the $10 billion free cash flow figure as very attainable, with significant growth beyond that into the next decade, as we execute on our record backlog and benefit from continued strong market demand. Okay, summing it all up, a strong first half with steady progress against our plan, resulting in a more balanced cash flow profile. We remain focused on continuing that momentum and building sustained free cash flow growth. With that, let's open up the line for questions.
