Price verdict withheld — owner-earnings floor unreliable
The five investor questions
2021–2025 (latest 5 aligned FYs; v3 window cap 5): revenue $17.8B to $11.3B, decreasing; diluted EPS 1.91 to -1.75, decreasing. Latest-filed diluted EPS remains usable for Business Trend, but an integer share-count change lacks enough evidence to confirm a comparable EPS basis; valuation growth therefore stays at 0%.
Median gross margin 52.4% over 10y, stable.
Median ROIC 1.3%, above the 12% hurdle in 0% of years.
Net debt/EBITDA 8.5x, interest coverage -1x.
Owner earnings trend unclear, share count n/a.
Price vs. conservative owner-earnings floor
A cautious baseline, not a price target: what the shares may support if normalized owner earnings simply hold steady.
- Owner earnings (normalized)
- Not reported
- Owner-earnings floor / share
- Unavailable — insufficient owner-earnings data
- Capped-growth comparison / share
- Unavailable — insufficient growth-model data
- Recent price
- $6.34
- Price vs. owner-earnings floor
- No price data
This floor assumes trailing owner earnings persist — unreliable for declining businesses. LUMN revenue fell in each of the three most recent year-over-year FY comparisons, so this floor is flagged as unreliable for this company.
Among the current top-score group, the median current price is 239% above the floor across 48 of the current top 50 companies by Moat Score with both values.

Model details under moat-index@3.0.0: zero-growth floor 11.1×, capped-growth comparison at no more than 18×; 9% discount rate; high-end growth 0% (capped at 4%) using min(5y revenue CAGR, 5y diluted-EPS CAGR), clamped to 0%–4%; maintenance capex uses min(capex, D&A); abstain when D&A is unavailable.

19 years of fundamentals
The business, in plain English
Lumen Technologies, Inc. booked $11.3B of revenue in FY2025 in the Communications sector and kept 41.4% of it as gross profit — a solid-margin business by that measure. After every other cost, −15.3% of each revenue dollar reached the bottom line.
Across the filed record, revenue grew from $2.6B (FY2008) to $11.3B (FY2025) — about 9.0% a year compounded over 17 years.
It earned −4.2% on invested capital in the latest filed year, FY2025. Across the full 18-year measurable filed record, median ROIC was 3.2%. Over the v3 recent window (10 measurable filed years), median ROIC was 1.3%. The Returns on Capital filter above scores it 0/100.
The balance sheet carried $17.4B of total debt in FY2025. Balance-Sheet Safety scores it 0/100.
Put together: Pricing Power is the strongest of the five filters (82/100) and Returns on Capital the weakest (0/100), which is how LUMN lands at 26/100 — 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.
Gaps in a line mean that item isn’t in LUMN’s filings for that year — the series is never interpolated or estimated. The Table view lists every filed value, including operating and net margins, total debt, and share count.

Track record
How Lumen Technologies, Inc.’s moat rated in each of the years we can reconstruct from its filings — scored only on what was knowable at the time — and what its price and returns did afterward. The score never saw a price; the two are joined only in hindsight, for education, not as a signal.
How to read this: each dot is what the engine would have scored LUMN on that December 31; the line below is its total-return price path (dividends reinvested) in the years since.
Two tracks, one timeline: the score has its own 0–100 scale (top), the price its own 100-based scale (bottom) — never a shared axis. The price path is a total-return (dividends reinvested) index built from the same data the forward returns use; gaps in the score line are years with no reconstructed rating (see the table for why). The Table view carries every value.
What followed, in the years it rated Wide
In the reconstructed history shown, LUMN did not rate Wide-moat in any year, so there is no wide-moat track record to report. That absence is itself the honest answer — we don’t manufacture a comparison where the rating never earned one.
