Group Structure
MAINLINE INFORMATION SYSTEMS, INC. sits 1 level below its ultimate parent, H.I.G. Middle Market Advisors IV, LLC. 5 subsidiaries are recorded beneath it, across 1 jurisdiction. The full chain up to H.I.G. Middle Market Advisors IV, LLC is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by MAINLINE INFORMATION SYSTEMS, INC.'s own shareholder record. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 5 subsidiaries span United States jurisdiction, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear.
