Reviewed cash-flow model

Reviewed operating-business exception limited to this annual period. CoStar supplies online real-estate marketplaces, information, analytics and digital-twin technology. It is an operating vendor, not a REIT. The filing supports the general cash-flow and operating-capital proxies while its FY2025 operating loss remains negative. Debt is reviewed at the $993m/$992m senior-note carrying amount, not the $140m future-interest schedule. Acquisitions and headquarters construction affect comparability. Consolidated FCF includes minority-owned operations; DCF and reverse DCF await a dated claim bridge. Business description ↗

This issuer explicitly confirms in its annual filing that it has never declared or paid cash dividends on its common/capital stock. Reviewed cash-dividend zero, bounded to fiscal period ending 2025-12-31. The exact statement and source filing are retained in the evidence record. This is explicit filing evidence, not an assumption from an absent cash-flow line. Surrounding source passage reviewed as the registrant’s own common-stock policy, not a subsidiary or predecessor statement.

Bounded FY2025-12-31 consolidated financing-statement extraction. Proceeds from exercise of stock options and employee stock purchase plan: 24000000 USD [csgp:ProceedsFromExerciseOfStockOptionsAndEspp]. All 4 financing lines reconcile exactly to reported financing cash flow -559000000 USD. Cash inflows from common shares, employee plans and option exercises are summed once as displayed on the statement; noncash compensation, withholding payments, preferred and noncontrolling interests are excluded. This review applies only to this issuer and fiscal period. Source limitation: the statement also aggregates other financing cash flows (net -8000000 USD). Their common-equity portion is not separately disclosed here. Issuance is the sum of separately reported common cash-issuance lines, not an independently verified gross total; additional equity flows may be inside those aggregates.
