Business quality

Moat Evidence

Not scored

A moat (a brand, a network, switching costs, patents, scale, a licence) is not a number in the filings, so Valerius doesn’t score it. Below are the figures and the words moat analysis starts from, from the company’s own 10-K filings. The conclusion is yours.

Return on capital, each year

Above 15% in 2 of 10 years (2016-2025); lowest 9.6%, highest 20.1%.

Gross margin, each year

Between 32.9% and 40.2% over 10 years (a range of 7.3 points).

Competition, in the company’s own words · 10-K filed Feb 26, 2026

The diagnostic information services industry remains fragmented, highly competitive and subject to new competitors. Competition is emerging from new technologies ( e.g. , digital pathology) and growing from non-traditional competitors ( e.g. , a government agency; providers of consumer-initiated testing). Increased hospital acquisitions of physician practices may enhance clinician ties to hospital-affiliated

The opening of the company’s “Competition” section in its 10-K, quoted word for word, not summarized or edited. It is the company’s own description, not Valerius’s view, and may include the company’s expectations. Open the filing.

Return on capital = operating income / (total assets − current liabilities), the ROIC row’s definition; 15% is the framework’s return threshold. Gross margin = gross profit / revenue. Both from each year’s 10-K via SEC EDGAR. Moat analysis commonly looks at whether returns and margins held up over many years. These figures don’t say whether the company has an advantage, what it is, or whether it will last.

Capital Allocation

4/5

Capital allocation, 2022-2025: dividends or buybacks paid in every year (pass); $3.59B paid out against $4.45B of free cash flow (pass); total debt $4.71B to $6.58B, up 39.7%, 3.0x EBITDA (fail: up more than 10% and above 2x EBITDA); shares outstanding 0.11B to 0.11B, down 0.7% (pass). 3 of 4 tests passed; the framework scores that as 4.

Filings

Company notices to the SEC

Not scored

Three kinds of event the company reported to the SEC in the last 5 years, from its filings on SEC EDGAR.

These are events the company reported to the SEC. An auditor change or a late filing can have many causes; each date links to the filing, where the company explains it. Valerius does not score these.

How the Graham and DCF values were calculated

  Graham Formula:
    IV = EPS x (8.5 + 2g) x (4.4 / Y)
    EPS = $9.42, g = 8.1%, Y = 4.5
    IV = $227.50
    Current price $235.00 vs Graham value $227.50 — price is 3.3% above the model value.

  DCF:
    FCF/share = $8.241
    Stage 1 growth = 9.2% for 5 years | terminal growth = 3.0% | discount rate = 10.0%
      Y1: $9.000 → PV $8.181
      Y2: $9.828 → PV $8.122
      Y3: $10.732 → PV $8.063
      Y4: $11.719 → PV $8.004
      Y5: $12.797 → PV $7.946
    Stage 1 PV sum = $40.32
    Terminal value at end of Y5 = $188.30
    PV of terminal value = $116.92
    DCF value = $157.24
    Current price $235.00 vs DCF value $157.24 — price is 49.5% above the model value.

Data from yfinance summary figures and financial statements, and from the company’s 10-K filings via SEC EDGAR; computed at a price of $235.00. Every score is calculated from the figures by the framework’s fixed rules, and the explanation beside it is generated from the same figures: Graham value, DCF value, margin of safety, ROIC, profit margins, debt-to-equity, price-to-book, EPS trend, ROE trend, free cash flow, retained earnings and capital allocation. No AI is involved in this scorecard. The moat is shown as evidence, without a score. Read each score with the figures beside it. Intrinsic value calculations are model outputs based on stated assumptions, not predictions.
