Thanks, Chris. Please recall that last quarter we made a number of expense reclassifications to reflect changes in how we manage our business in connection with the recent launch of the Spectrum Business brand. Again, these reclassifications did not result in any changes to total operating expenses or adjusted EBITDA for any period. Let's please turn to our customer results on slide nine. Including residential and small business, we lost 117,000 internet customers in the still seasonal second quarter, compared to a loss of about 100,000 in last year's 2Q when adjusted to remove last year's impact of about 50,000 ACP related disconnects. When comparing this year's second quarter internet net adds versus last year's 2Q, we have not adjusted our second quarter 2024 internet net adds for the 50,000 ACP related gross add headwind we called out last year when comparing to 2023, as neither the second quarter of 2025 nor 2024 had the benefit of ACP related gross additions. In mobile, we added 500,000 lines with higher gross additions year-over-year, offset by a lower year-over-year churn rate on a larger line base. Video customers declined by 80,000 versus a loss of 408,000 in 2Q24, our best video quarter since 2021 with the improvement primarily driven by better connects year-over-year resulting from the new pricing and packaging we launched last fall and lower churn year-over-year driven in part by our programmer app inclusion packaging. Wireline voice customers declined by 220,000.
In rural, we activated our 1 millionth subsidized rural passing during the second quarter. Success in rural has benefited from both the scale and experience we bring to the complex process of network construction. During the quarter, we grew our subsidized rural passings by 123,000 and by over 440,000 over the last 12 months, and we generated 47,000 net customer additions in our subsidized rural footprint in the quarter. We continue to expect rural passings growth of approximately 450,000 in 2025 in addition to continued non-rural construction and fill-in activity.
Moving to second quarter revenue results on slide 10. Over the last year, residential customers declined by 2.1% while residential revenue per customer relationship grew by 1.7% year-over-year given promotional rate step-ups, rate adjustments, and the growth of Spectrum Mobile. Those factors were partly offset by a higher mix of non-video customers, growth of lower-priced video packages within our base, and $67 million of costs allocated to programmer streaming apps and netted within video revenue. This allocation should grow over time as more customers authenticate into our streaming application offers, but is neutral to EBITDA. As slide 10 shows, in total, residential revenue declined by 0.4%. Turning to commercial revenue, total commercial revenue grew by 0.8% year-over-year with mid-market and large business revenue, formerly Spectrum Enterprise, growth of 2.9%. And when excluding all wholesale revenue, mid-market and large business revenue grew by 3.5%. Small business revenue declined by 6% reflecting a decline in small business customers with revenue per customer remaining essentially flat year-over-year. Second quarter advertising revenue declined by 6.7% including the impact of less political revenue. Excluding political advertising, revenue decreased by 4.4% due to a more challenged national and local advertising market partly offset by our higher advanced advertising and better inventory selling capabilities. Other revenue grew by 18.9% primarily driven by higher mobile device sales and a $45 million one-time benefit. In total, consolidated second quarter revenue was up 0.6% year-over-year.
Moving to operating expenses and adjusted EBITDA on slide 11. In the second quarter, total operating expenses increased by 0.6% year-over-year. Programming costs declined by 8.8% due to a 5.1% decline in video customers year-over-year and a higher mix of lighter video packages and $67 million of costs allocated to programmer streaming apps and netted within video revenue, partly offset by higher programming rates. Other costs of revenue increased by 7.3% primarily driven by higher mobile device sales and mobile direct service costs. Cost to service customers, which combines field and technology operations and customer operations, increased 3.8% year-over-year, primarily due to higher bad debt expense due to prior year cash basis accounting treatment for certain ACP customers, and higher mobile device sales, higher network utility costs, labor related costs primarily driven by recent storm activity and banking card fees, partly offset by productivity from our tenure investments. Excluding bad debt, cost to service customers grew 2.4% year-over-year. Marketing and residential sales expense grew by 8.6% due to slightly higher sales volume as we make investments in marketing and sales including in higher cost sales channels to drive growth. Finally, other expense increased by 6%.
Before turning to adjusted EBITDA, I wanted to note that there were a number of storms and tornadoes, particularly in the St. Louis area, Ohio, and the broader Midwest that impacted our footprint in the second quarter. We extend our sympathies to those impacted. The combination of bill credits and storm cleanup expenses spread across our expense lines resulted in a $13 million headwind to EBITDA year-over-year. The capex impact was very small. Adjusted EBITDA grew by 0.5% year-over-year in the quarter. We expect to grow adjusted EBITDA for the full year 2025 and year-to-date we're on track with the first half EBITDA growth of 2.6%. EBITDA growth will be pressured in the third and fourth quarters given last year's political advertising strength. Turning to net income, we generated $1.3 billion of net income attributable to Charter shareholders in the second quarter compared to $1.2 billion last year given this quarter's higher adjusted EBITDA and lower interest expense.
Turning to slide 12, capital expenditures totaled just under $2.9 billion in the second quarter, flat with last year's second quarter, with higher network evolution and CPE spend offset by lower line extension spend. We now expect total 2025 capital expenditures to reach approximately $11.5 billion versus $12 billion previously, primarily due to the timing of network evolution spend and lower line extension spend spread in commercial and subsidized rural. The majority of the $500 million spending shortfall this year will be spent next year in 2026. On a standalone basis, we still expect 2025 to be our peak capital spend year in dollar terms. 2025 should also be our peak year of capital intensity even including the impact of the Cox transaction and associated integration capital assuming that it's closed, with capital intensity falling going forward. And given the powerful economic and strategic benefits of our Cox transaction, the pro forma entity will generate higher free cash flow per share in spite of delevering which will reduce our cost of capital.
Turning to free cash flow on slide 13, second quarter free cash flow totaled $1 billion, a decline of $250 million year-over-year. The decline was primarily driven by higher cash taxes, higher cash interest, and a working capital headwind related to mobile handsets. Turning to second quarter and full year 2025 cash taxes. On our last call, I noted that we expected to pay approximately $1 billion in second quarter cash taxes. In the end, we ended up paying less than that, approximately $650 million given the timing of certain tax related items. Looking forward, new federal tax legislation passed by Congress and signed into law in July has improved our cash tax outlook for the full year. We now expect that our calendar year 2025 cash tax payments will total a bit over $1 billion, down from a range of $1.6 to $2 billion previously driven by our ability to depreciate more for tax purposes this year given the permanent restoration of 100% bonus depreciation, our ability to now deduct more interest for tax purposes given the permanent restoration of the EBITDA based limitation, and our ability to now fully deduct research and experimentation expenditures for tax purposes.
The new tax legislation will ultimately save us several billion dollars in cash taxes over the next five years, helping to finance our capital expenditures and investments and supporting our free cash flow for at least the next 5 years while creating higher free cash flow per share essentially permanently. We appreciate the efforts of President Trump and Congress to restore these key business tax provisions which will provide capital-intensive companies like ours the visibility to continue pursuing our long-term investments including the significant investments we will make in the Cox network, driving benefits for customers and employees and improving our competitiveness. We finished the second quarter with $94.3 billion in debt principal. Our weighted average cost of debt remains at an attractive 5.2%. And our current run rate annualized cash interest is $4.9 billion. During the quarter, we repurchased 4.5 million Charter shares and Charter Holdings common units totaling $1.7 billion at an average price of $375 per share. As of the end of the second quarter, our ratio of net debt to last 12-month adjusted EBITDA increased sequentially to 4.1 times and stood at 4.18 times pro forma for the pending Liberty Broadband transaction.
As I mentioned on our Cox transaction investor call on May 16th, during the pendency of the Cox deal, we plan to be at or slightly under 4.25 times leverage pro forma for the Liberty transaction post close. However, we will move to our long-term target leverage to 3.5 to 4.0 times and we would expect to delever to the middle of that range within 2 to 3 years following close. I will leave you with a few things. Our share of converged connectivity revenue within our footprint is still low, less than 30%. And with better products and pricing, we have a long runway for organic customer, top-line, EBITDA, and free cash flow growth for many years to come. We've made and are making the investments required to accelerate the growth of the business going forward, including network evolution, new pricing and packaging, innovations in seamless connectivity and entertainment, mobile service, investments in AI, and employee tenure. Our free cash flow is about to surge. We are now in the midst of our peak capital intensity period and moving beyond that peak on its own sets us up for rapid free cash flow and free cash flow per share growth over the next several years as capital intensity declines meaningfully. And finally, we plan to add to all of that our combination with Cox which provides meaningful share price and free cash flow accretion to our shareholders. With that, I'll turn it over to the operator for Q&A.
