This quarter's webcast, earnings release, and presentation, which include relevant disclosures and non-GAAP reconciliations, are available on our website. As we start this year, we've set the foundation for our turnaround with stronger performance and record-breaking backlogs across our businesses. We delivered 600 airplanes and won more than 1,100 commercial orders for the year, making this one of our highest order totals ever, as our portfolio continues to win in the market. To do this, the fundamental changes we've made this past year will serve as a base for continuous improvement as we look to increase commercial production.
As previously announced, we're also investing in the future, breaking ground on our factory expansion to support higher rates and meet the exceptional demand for the 787. Before the year-end, we took another important step forward, supporting our production stability by completing the acquisition of Spirit AeroSystems. BGS secured Boeing's largest-ever commercial component services deal, and our government services business received its highest orders ever in 2025, including a contract with the U.S. Demand for the airplane remains strong, and we remain confident that the 777X will be the next flagship airplane for our global customers.
Revenue was up 57%, primarily driven by improved operational performance across the business, including higher commercial deliveries and defense volume. Core earnings per share of $9.92 primarily reflects the $11.83 gain associated with closing the Digital Aviation Solutions divestiture. Revenue of $11.4 billion and operating margin of negative 5.6% both improved materially and primarily reflect better operational performance and higher deliveries compared to last year's results that were impacted by the work stoppage. Results also include impacts associated with acquiring Spirit AeroSystems, which impacted segment margins by roughly 1.5 points in the quarter.
