The five investor questions

49

2021–2025 (latest 5 aligned FYs; v3 window cap 5): revenue $703M to $1.0B, increasing; diluted EPS 0.24 to -3.04, decreasing.

72

Median gross margin 51.8% over 10y, stable.

0

Median ROIC -30.8%, above the 12% hurdle in 0% of years.

28

Net debt/EBITDA n/ax, interest coverage -24x.

44

Owner earnings changed trend unclear over up to the ten most recent annual observations, share count n/a.

This zero-growth estimate assumes trailing owner earnings persist — unreliable for declining businesses. The recent FY revenue series does not trigger the three-consecutive-declines flag.

Among the current top-score group, the median current price is 239% above the zero-growth estimate across 48 of the current top 50 companies by Moat Score with both values.

15 years of fundamentals

The business, in plain English

Tandem Diabetes Care, Inc. booked $1.0B of revenue in FY2025 in the Healthcare sector and kept 53.8% of it as gross profit — a solid-margin business by that measure. After every other cost, −20.2% of each revenue dollar reached the bottom line.

Across the filed record, revenue grew from $2.5M (FY2012) to $1.0B (FY2025) — about 58.8% a year compounded over 13 years.

It earned −39.5% on invested capital in the latest filed year, FY2025. Across the full 12-year measurable filed record, median ROIC was −36.8%. Over the v3 recent window (10 measurable filed years), median ROIC was −30.8%. The Returns on Capital filter above scores it 0/100.

The balance sheet carried $310M of total debt in FY2025. Balance-Sheet Safety scores it 28/100.

Put together: Pricing Power is the strongest of the five filters (72/100) and Returns on Capital the weakest (0/100), which is how TNDM lands at 39/100 — a None moat.

This breakdown is generated from the filed numbers and sub-scores above — no outside narrative, no estimates. Where a filing doesn’t disclose an input, the sentence that would need it is omitted instead of guessed.

Insider activity

Form 4 reports mix P/S market or private transactions with compensation-plan mechanics. Activity casually described as “insider selling” can include compensation mechanics; awards, tax withholding, and option exercises are shown by their exact filed class here, never collapsed into “Bought” or “Sold.”

These are disclosed filing facts and arithmetic aggregates, not a signal or verdict.

This machine-readable surface covers SEC ownership filings from 2003; it does not represent earlier paper-era records.
