Margin gains broadened, while cash generation strengthened the balance sheet and supported a higher dividend. Management expects faster same-store growth for 2026 and additional modular capacity by late summer 2027. Although demanding comparisons, elevated capital spending, labor constraints and technology project concentration are concerning, growing market tailwinds have been encouraging.
