Thank you, Kathy, and good morning, everyone. I'll begin by covering the company's second quarter financial results summarized on slide four. Overall, it was a solid quarter with increasing momentum. The robust demand environment we outlined on our last call continues to be converted into new bookings and sales. Second quarter awards totaled $20 billion, driving backlog up 17% year-over-year to $105 billion. Sales in the quarter accelerated to $10.9 billion with sequential sales up 10% and year-over-year sales up 5%. Segment operating income decreased slightly compared to the prior year. Keep in mind the second quarter of 2025 benefited from a $76 million favorable EAC adjustment on Sentinel. Earnings per share was $7.68, benefiting from a lower effective tax rate. Capital expenditures totaled $32 million and continue to ramp as we invest to expand our facilities to support customer demand. Q2 adjusted free cash flow was nearly $1 billion, a significant increase compared to the prior year.
Turning to segment performance, I'll start with aeronautics on slide five. AS delivered outstanding operational performance in the second quarter with double-digit sales and margin growth. Sales increased 13% driven by higher volumes on B-21, Taco, and mature production programs. On the bottom line, AS delivered a margin rate of 10.3% driven by strong performance across production and sustainment programs. Turning to DS, second quarter sales increased 5% and 7% on an organic basis. Higher sales were driven by the continued ramp on Sentinel and missile defense programs. Operating margin was 7.5%. Strong performance across the portfolio was partially offset by a $68 million unfavorable adjustment on SAW related to an increase in projected cost to support the design and qualification of the system. Apart from SAW, the rest of the DS portfolio contributed an OM rate of 11% in the second quarter, which gives us confidence in delivering improved returns in the second half. Backlog at DS increased to nearly $35 billion, driven by an increase of $7.6 billion on Sentinel.
Our mission systems business continued to generate outstanding bottom-line performance with strong execution across the portfolio. Sales were up 3% in the quarter, supported by higher volumes on marine programs, F-35 sensors, and increases on restricted airborne radar programs. Margin rates improved to 15.4% driven by strong performance and higher net favorable EAC adjustments across the business. And at space, sales increased by 4% driven by higher volume on NASA's commercial resupply service mission and missile defense programs. Second quarter operating margins were 8.6%. This included an unfavorable EAC adjustment on GEM 63 XL related to increases in the estimated cost and quantity of materials needed to complete the program. The rest of the space portfolio contributed an OM rate of over 11%, supporting our ability to deliver second half results north of 11%.
On slide nine, you'll see our second quarter diluted EPS was $7.68. The prior period included a benefit of $14 associated with the training services divestiture. Normalizing for this transaction, Q2 EPS increased by 57 cents. This improvement was largely driven by the remeasurement of uncertain tax positions given recent developments with the IRS and from a gain associated with the sale of an equity investment. Turning to company level guidance on slide 10. As Kathy outlined earlier in the call, we are increasing our sales guidance to a range of $43.75 to $44.25 billion. This outlook reflects a second half step up in sales that is similar to the profile we experienced last year. With this in mind, we anticipate mid to high single-digit year-over-year sales growth in Q3. We are increasing our mark-to-market adjusted EPS guidance to a range of $28.60 to $29.10, an increase of $1.20. This reflects solid segment performance in the second half and an effective tax rate of mid-14%. We are reaffirming our outlook for segment operating income which we are confident will improve in the second half and we are reaffirming our guidance range for adjusted free cash flow of $3.1 billion to $3.5 billion. Adjusted free cash flow includes several hundred million weeks. This event accelerated cash receipts associated with the sale but shifted other payments on the program out beyond this year. Net net, it doesn't change our expectations for 2026 cash on the program or the company. Our adjusted free cash flow non-GAAP metric is consistent with our prior treatment from a few years ago when we had a similar event. We continue to expect $1.85 billion of capex in 2026. And as we previously shared, we expect capex investments of around 4.5% of sales in 2027 and 2028 as we invest in infrastructure to support the B-21 production ramp.
Turning to segment level guidance at AS, we are increasing both our top and bottom line estimates for the year. We now anticipate sales of approximately $14 billion. This outlook reflects higher B-21 sales as the program continues to ramp as well as higher volumes on mature production programs. On the bottom line, we are raising AS's operating margin rate to the mid to high 9% range, reflecting strong performance in the first half of the year and continued positive expectations for the second half. For DS, we are maintaining our outlook for sales in the mid to high $8 billion range and margins of approximately 10%. Second half revenues are expected to step up more than $700 million driven by higher ammunition sales and production timings in our weapons portfolio as well as continued growth in Sentinel and IBCS. Second half margin rates are expected to improve to over 11% consistent with our first half performance excluding EACs associated with our missile prime investments. At Mission Systems, we are maintaining our guidance of high $12 billion in 2026 sales while raising our margin rate expectations to approximately 15%. This outlook is underpinned by a sequential second half sales increase of more than $600 million driven by higher sales volumes on production programs and new awards. Turning to space, we continue to expect approximately $11 billion in sales for the year. Following the pattern in the other businesses, second half sales are expected to increase significantly. This growth is primarily driven by higher volumes on national security space programs, new awards, and improved performance on GEM 63 XL. On the bottom line, we are lowering our expectation for margin rate to the low 10% range to reflect the margin pressure experienced to date. Performance remains strong across the majority of the space portfolio, and we're confident in delivering improved second half performance. Our last guidance update for the quarter relates to inter-segment eliminations which we expect to be approximately $2.7 billion driven by increased volumes of restricted work at MS and Sentinel support in the space segment. We anticipate the inter-segment OM rate to be in the mid 3% range. In summary, building on the momentum established in the first half, we remain on track to deliver on our updated full-year projections. Our confidence is underpinned by the enduring demand for our capabilities, record backlog, and alignment of our portfolio to global defense priorities. We've made significant investments in our business that position the company for accelerated growth. And we continue to be disciplined in our capital deployment strategy, creating value for all of our stakeholders. With that, let's open the call for Q&A.
