ALTAIR ENGINEERING INC.
ALTAIR ENGINEERING INC. is a registered legal entity registered in United States under 601952000, and its current status with Washington Secretary of State is active. The company was incorporated on 13 August 2010 and lists its registered address as TROY, United States. 5 shareholders are on record for ALTAIR ENGINEERING INC., and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Washington Secretary of State and was last updated on 5 October 2026.

Shareholders
5
Five shareholders are currently on record for ALTAIR ENGINEERING INC., reflecting the stock ledger maintained under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.
The largest of these is Matrix Capital Management, holding 26.8% — the largest recorded stake — followed by Blackrock Inc. at 16.1%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 20 shareholders in total, though only the top 5 by holding are shown in this view.
Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Officers
3
Three officers are currently on record for ALTAIR ENGINEERING INC., filed with Washington Secretary of State. RAOUL MAITRA, JAMES SCAPA and Matthew Brown all serve as Governingperson.
Management authority at ALTAIR ENGINEERING INC. sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
ALTAIR ENGINEERING INC. sits 3 levels below its ultimate parent, Siemens AG, registered in Germany. 38 subsidiaries are recorded beneath it, across 19 jurisdictions. The full chain up to Siemens AG is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by ALTAIR ENGINEERING 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 38 subsidiaries span United States, Italy, Germany, Taiwan, Canada, Australia, and 13 more jurisdictions, 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. Six of the 38 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
