TANDEM DIABETES CARE, INC. is a Public Limited Company registered in United States under 3087400, and its current status with California Secretary of State — bizfile Online is active. The company was incorporated on 13 February 2008 and lists its registered address as SAN DIEGO, United States. 5 shareholders are on record for TANDEM DIABETES CARE, 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 California Secretary of State — bizfile Online and was last updated on 3 October 2026.

Shareholders

5

Five shareholders are currently on record for TANDEM DIABETES CARE, 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 Vanguard Group Inc, holding 12.8% — the largest recorded stake — followed by iShares Trust-iShares Core S&P Small-Cap ETF at 7.1%; the remaining 3 shareholders shown hold smaller stakes.

The register reports 8 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.

Group Structure

TANDEM DIABETES CARE, INC. has no recorded parent company — it sits at the top of its own group structure, with 8 subsidiaries recorded beneath it across 5 jurisdictions. 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 8 subsidiaries span United States, Netherlands, Switzerland, United Kingdom, Canada 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. One of the 8 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
