The five investor questions

65

2021–2025 (latest 4 aligned FYs; v3 window cap 5): revenue $34M to $53.7M, increasing; diluted EPS -1.73 to 2.42, increasing. 1 fiscal year was not jointly reported; CAGR uses the full 4-year elapsed span. 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%.

Not enough years of gross-margin data to score pricing power.

Median ROIC -42.4%, above the 12% hurdle in 0% of years.

Net cash position — no leverage risk.

Owner earnings changed trend unclear over up to the ten most recent annual observations.

The pricingPower component abstained: Not enough years of gross-margin data to score pricing power. The other four 20% weights were renormalized over the scored 80%.

Price vs. value if growth stopped today

A cautious baseline, not a price target: what the shares may support if normalized owner earnings simply hold steady.

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 238% above the zero-growth estimate across 49 of the current top 50 companies by Moat Score with both values.

Model details under moat-index@3.0.0: zero-growth multiple 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. This is a disclosed model range, not intrinsic value as fact.

10 years of fundamentals

The business, in plain English

Across the filed record, revenue grew from $5.3M (FY2018) to $53.7M (FY2025) — about 39.1% a year compounded over 7 years.

ROIC is not available for the latest filed year, FY2025. Across the full 3-year measurable filed record, median ROIC was −42.4%. Over the v3 recent window (3 measurable filed years), median ROIC was −42.4%. The Returns on Capital filter above scores it 0/100.

FIXX's latest filed year, FY2025, doesn't disclose total debt in a form the methodology can use, so current leverage is treated as unmeasured — never assumed to be zero.

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.

The explained ROIC gaps have filed inputs but no meaningful positive invested-capital denominator. Other gaps mean the item is not in the 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.

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.

The insider-filing service is temporarily unavailable, so no partial or guessed answer is shown for FIXX.
