| Segment Reporting |
10.SEGMENT REPORTING The Company’s revenues are generated primarily from the collection, transfer, recycling and disposal of non-hazardous solid waste and the treatment, recovery and disposal of non-hazardous E&P waste. No single contract or customer accounted for more than 10% of the Company’s total revenues at the consolidated or reportable segment level during the periods presented. For the six months ended June 30, 2026, the Company managed its operations through the following six geographic solid waste operating segments: Southern, Western, Eastern, Central, Canada and MidSouth. The Company’s six geographic solid waste operating segments comprise its reportable segments. Each operating segment is responsible for managing several vertically integrated operations, which are comprised of districts. Certain corporate or regional overhead expense allocations may affect comparability of the segment information presented herein on a period-over-period basis. The Company’s Chief Operating Decision Maker (“CODM”) is the Company’s President and Chief Executive Officer. The CODM evaluates operating segment profitability and determines resource allocations based on several factors, of which the primary financial measure is segment EBITDA. The Company defines segment EBITDA as earnings before interest, taxes, depreciation, amortization, impairments and other operating items, and other income (expense). Segment EBITDA is not a measure of operating income, operating performance or liquidity under GAAP and may not be comparable to similarly titled measures reported by other companies. The Company’s management uses segment EBITDA in the evaluation of segment operating performance as it is a profit measure that is generally within the control of the operating segments. Summarized financial information concerning the Company’s reportable segments for the three and six months ended June 30, 2026 and 2025, including a reconciliation of segment EBITDA to Income before income tax provision, is shown in the following tables: | | | | | | | | | | | | | | | | | | | | | | | | | | Three Months Ended | | | | | | | | | | | | | | | | | | | | | | | | | | June 30, 2026 | | Southern | | Western | | Eastern | | Central | | Canada | | MidSouth | | Corporate (a), (f) | | Consolidated | | Revenue | | $ | 581,579 | | $ | 562,543 | | $ | 542,211 | | $ | 478,513 | | $ | 425,486 | | $ | 366,344 | | $ | — | | $ | 2,956,676 | | Intercompany revenue (b) | | | (62,929) | | | (69,818) | | | (98,257) | | | (54,752) | | | (39,719) | | | (69,594) | | | — | | | (395,069) | | Reported revenue | | | 518,650 | | | 492,725 | | | 443,954 | | | 423,761 | | | 385,767 | | | 296,750 | | | — | | | 2,561,607 | | | | | | | | | | | | | | | | | | | | | | | | | | | | Segment expenses (c) | | | (347,806) | | | (358,989) | | | (322,310) | | | (268,834) | | | (217,855) | | | (216,061) | | | (7,855) | | | (1,739,710) | | | | | | | | | | | | | | | | | | | | | | | | | | | | Segment EBITDA (d) | | | 170,844 | | | 133,736 | | | 121,644 | | | 154,927 | | | 167,912 | | | 80,689 | | | (7,855) | | | 821,897 | | Segment EBITDA margin | | | 32.9 | % | | 27.1 | % | | 27.4 | % | | 36.6 | % | | 43.5 | % | | 27.2 | % | | | | | 32.1 | % | | | | | | | | | | | | | | | | | | | | | | | | | | | Depreciation and amortization | | | (67,774) | | | (57,230) | | | (60,357) | | | (46,341) | | | (52,747) | | | (37,414) | | | (4,014) | | | (325,877) | | Other segment items (e) | | | (1,329) | | | (29,956) | | | (1,357) | | | 28 | | | 355 | | | (478) | | | (79,553) | | | (112,290) | | | | | | | | | | | | | | | | | | | | | | | | | | | | Income before income tax provision | | | | | | | | | | | | | | | | | | | | | | | $ | 383,730 | | | | | | | | | | | | | | | | | | | | | | | | | | | | Capital expenditures | | $ | 63,442 | | $ | 50,206 | | $ | 57,287 | | $ | 45,889 | | $ | 31,335 | | $ | 42,307 | | $ | 62,937 | | $ | 353,403 | | Total assets (g) | | $ | 4,743,442 | | $ | 3,659,006 | | $ | 3,783,675 | | $ | 2,929,482 | | $ | 3,616,417 | | $ | 2,074,085 | | $ | 593,345 | | $ | 21,399,452 | |
