We're well-positioned for 2026, as we're already realizing the benefits of technology and innovation. We look forward to expanding their application throughout our operations as we leverage the power of human capital to “Win from Within” in 2026. We see the dedication of our approximately 25,000 employees as the ultimate differentiator and remain humbled by their commitment to put our values into action.
In 2025, we deployed approximately $2.2 billion for capital expenditures and acquisitions to reinvest in and expand our business, while preserving the strength and flexibility of our balance sheet. We completed 19 acquisitions totaling approximately $330 million in annualized revenues across our footprint. These include new market entries providing platforms to expand in Florida and New York; strategic investments in recycling facilities in New Jersey complementing our leading position in the New York City commercial franchise zones; tuck-in acquisitions reinforcing existing positions across several of our markets; and new West Coast franchises. We also furthered our sustainability-related investments through continued progress on our portfolio of renewable natural gas facilities under development and a state-of-the-art recycling facility under construction.
During the year, we returned an aggregate of $839 million to shareholders, including through record share repurchases totaling over $505 million, plus cash dividends of $334 million. Our regular quarterly cash dividend has grown at a compound annual growth rate of 13.9% through fifteen consecutive, double-digit percentage annual per share increases since initiation.
During 2025, we further diversified our funding sources through an underwritten public offering of $500 million in senior notes, and remain well-positioned for future growth opportunities, with debt-to-EBITDA3 leverage of 2.75 times and liquidity of over $625 million.
Delivering in 2025: Excellence with Humility
2025 revenue of $9.467 billion reflects an increase of 6.1% from the prior year and drove adjusted EBITDA2 of $3.125 billion, up 7.7% from the prior year. Industry-leading reported adjusted EBITDA2 margin of 33.0% increased by 50 basis points. Moreover, underlying margin expansion in solid waste hauling, transfer and disposal increased by over 100 basis points in 2025.
We attribute our success to the strength of our operating teams to deliver on our commitments in the face of a challenging macro environment, which we addressed through our purposeful culture and disciplined execution. We overcame pressure on reported margins related to a second consecutive year of declines in values for recycled commodities and renewable energy credits, as well as continued weakness in underlying solid waste volumes. Outsized margin expansion from price-led organic growth in solid waste was augmented by a continued focus on human capital and the realization of benefits from ongoing improvements in employee retention and safety.
HUMAN CAPITAL DRIVES RESULTS: 2025 also marked our third consecutive year of outsized progress in employee retention and safety performance. Voluntary turnover declined by another 17% in 2025, bringing multi-year reductions to approximately 55%, providing increased employee engagement through optimized staffing levels and reduced overtime. We've also seen a corresponding increase in customer engagement and satisfaction from increased consistency in communication and service quality.
Along with improved employee retention, we saw another year of improvement in safety performance, with incident rates decreasing to historic Company levels resulting in a multi-year reduction of over 30%. That improvement included a 13% decrease during 2025, when over 65% of operating locations showed year-over-year improvement or had perfect safety scores for the year. We exited the year at our lowest levels, with monthly incidents down 15% year over year in spite of ongoing growth.
Looking Ahead to 2026: Investing in the Future
In 2025, we positioned ourselves for further growth and opportunities for value creation in 2026 and beyond. By completing another outsized year of solid waste-focused acquisition activity, we are set up for rollover contribution of approximately $125 million in 2026. We are also well-positioned for another year of price-led organic growth in solid waste to drive outsized underlying margin expansion, along with the improving trends in employee retention and safety already experienced.
