Ferrovial shows a complex structure with significant equity adjustments, substantial debt across infrastructure projects, and notable noncontrolling interests. The inputs include negative equity components (Measurement Adjustment), large Reserves, and substantial cash flows from financing activities, but no explicit mention of hybrid bonds in the financial statements. Hybrids typically require stable earnings, solid credit metrics, and appropriate regulatory capital treatment; Ferrovial’s earnings fluctuated (Profit Loss from continuing operations 238m; comprehensive income positive 889m) and the company has high long-term borrowings and complex project financing. However, lack of explicit hybrid issuance history or dedicated regulatory capital treatment details makes assessment uncertain. Given partial indicators but insufficient explicit data on hybrids, I classify as Insufficient Data.
