Strong business, priced for a lot of it - 26 of 36 checks passed.
Value
What you pay today for what the business produces, measured against REGN's own history and its peers, never a universal rule.
Expensive against its own history and its sector - you're paying up for what you get.
Is the price high or low right now, compared to what the market usually pays?
→At 20.8x earnings, the market is paying +13% more than REGN's own 11-year median of 18.4x. Expectations are elevated, so more has to go right to justify the price.
What has the market paid for REGN over the years?
◌ 2026 = at the latest close (2026-09-04), over the trailing twelve months; earlier years are annual averages
→At 20.8x earnings, the market is paying +13% more than REGN's own 11-year median of 18.4x. Expectations are elevated, so more has to go right to justify the price.
What cash return does the business throw off per dollar of market value?
4.8%FCF yield today
◌ 2026 = at the latest close (2026-09-04), over the trailing twelve months; earlier years are annual averages
→At 4.8%, the business is throwing off more cash per dollar of market value than its own 11-year median of 4.4% - the cheaper end of its history.
What does “Value” actually mean?
Value asks what you pay for each dollar of earnings, sales or cash the business produces. A high multiple isn't automatically bad - fast growers earn theirs - but a price far above the company's own history means the market expects a lot to go right. We compare each multiple to the company's own past and to its sector, never to a universal rule.

Growth
What the company has actually reported - is it selling more, and is more of it becoming profit?
Growth is weak or inconsistent - the trend, not the story, is the problem.
Revenue: is the business selling more than it used to?
◌ 2026 = trailing twelve months to the latest filed quarter, not a full fiscal year
→Revenue reached $14.3B in 2025, compounding +6% a year since 2022 though the pace has cooled. The trailing twelve months are already running at $15.5B, ahead of the last full year.
Net income: how much of that revenue becomes profit?
◌ 2026 = trailing twelve months to the latest filed quarter, not a full fiscal year
→Net income was $4.5B in 2025, compounding +1% a year over three years. Trailing twelve-month profit stands at $4.3B.
How fast is it growing, year by year?
+1%revenue growth, FY 2025
→In 2025 revenue grew +1% while earnings moved +2% - when the earnings line runs above revenue, each new dollar of sales is arriving more profitably.
What does “Growth” actually mean?
Growth here is what the company has actually reported to the SEC - not a forecast. We look at the last year, the three-year pace, whether growth is speeding up or slowing down, and whether it's been consistent rather than one lucky year. Hatched bars are fourth quarters we derived from annual filings (companies file a full-year 10-K rather than a Q4 report).
How we scored it · 2 of 6 checks passed
| ✕ | Outgrew its sector last year | 9.3% vs 13.6% (sector 70th pct, n=254) |
| ✕ | Sustained growth beats its sector (3 years) | 5.6% vs 14.9% (sector 70th pct, n=247) |
| ✕ | Profits grew last year | -2.9% vs 0.0% |
| ✕ | Profit growth beats its peers | 2.8% vs 7.9% (sector 70th pct, n=96) |
| ✓ | Growth is speeding up, not slowing | 1y 9.3% vs 3y 5.6% |
| ✓ | Grew per share, not just in total | 23.1% vs 0.0% |
Quality
Whether the growth makes real money - margins, returns on capital, and whether profits turn into cash.
Rare profitability: margins and returns on capital are well above its peers.
Margins: of every $1 of sales, how much survives each cost layer?
◌ 2026 = trailing twelve months to the latest filed quarter (2026-06-30), not a full fiscal year
→Operating margin compressed 14 points to 25% since 2022. After everything, 31 cents of each sales dollar reaches net profit. REGN doesn't tag a gross-profit line in its filings, so the chart starts at operating margin.
Earnings quality: do the reported profits turn into real cash?
◌ 2026 = trailing twelve months to the latest filed quarter (2026-06-30), not a full fiscal year
→Operating cash flow tracks reported profit almost exactly (108%). The earnings are real cash, not accounting.
What does it earn on the money it uses?
◌ 2026 = trailing twelve months to the latest filed quarter (2026-06-30), not a full fiscal year
→ROE 14% and ROCE 10% sit close together - the returns come from the business itself, not from borrowing.
How much of every sales dollar ends up as free cash?
◌ 2026 = trailing twelve months to the latest filed quarter, not a full fiscal year
→28 cents of every sales dollar became free cash in 2025, down 8 points since 2022.
What does staying competitive cost, per dollar of sales?
◌ 2026 = trailing twelve months to the latest filed quarter (2026-06-30), not a full fiscal year
→The biggest claim on each sales dollar is research and development, at 41% of revenue (stock compensation 7%, capital spending 6%). That share has risen since 2022, so the cost of competing is climbing.
When sales grow, do profits grow faster?
→Operating profit outgrew revenue in only 1 of the last 5 years. Costs are growing roughly in step with the business, so scale isn't yet paying for itself.
Does REGN earn more on its capital than that capital costs?
→REGN earns 9.9% on the capital it employs, below the 10% most investors treat as the cost of capital. It was 18.2% in 2022, so the trend is down, though the pace has cooled.
What does “Quality” actually mean?
Quality asks whether the growth makes real money. Margins show how much of each sale survives costs; return on equity shows what shareholders earn on their capital; and the profit-to-cash comparison catches companies whose accounting profits never turn into actual cash.
How we scored it · 6 of 6 checks passed
| ✓ | Better gross margins than peers | 98.6% vs 59.8% (sector 70th pct, n=117) |
| ✓ | Runs leaner than peers (operating margin) | 24.7% vs 9.8% (sector 70th pct, n=245) |
| ✓ | Actually profitable | TTM net income $4.3B |
| ✓ | Earns well on shareholders' money | 13.7% vs 9.2% (sector 70th pct, n=248) |
| ✓ | Earns a real return on the capital it employs | 10.6% vs 10.0% |
| ✓ | Profits are cash, not accounting | 1.08 vs 0.80 |
Health
The balance sheet stress test: could REGN survive a bad year?
A fortress balance sheet - REGN can survive a very bad year.
Could it handle its debt if things went wrong?
◌ 2026 = the latest balance sheet (2026-06-30), not a fiscal year-end
→The company holds $8.0B in cash against $2.0B of debt - a net-cash balance sheet, which means a bad year is an inconvenience rather than a threat.
Is the company's own capital growing or shrinking?
→The company's own capital grew from $26.0B in 2023 to $31.7B (+22%). The business is building book value rather than consuming it.
What does “Health” actually mean?
Health asks one question: can the business survive a bad year? We check whether near-term bills are covered, whether debt is modest and shrinking, whether earnings comfortably pay the interest, and - for loss-makers - how many years of cash are left at the current burn rate.
How we scored it · 6 of 6 checks passed
| ✓ | Comfortable near-term liquidity | 3.34 vs 1.50 |
| ✓ | Debt isn't dominating | 0.06 vs 1.00 |
| ✓ | Debt trending the right way | debt/equity 0.06 now vs 0.11 five years ago |
| ✓ | Earnings cover the interest | 69.37 vs 5.00 |
| ✓ | Converts sales to cash better than its sector | 30.1% vs 15.2% (sector 70th pct, n=266) |
| ✓ | Self-funding | TTM free cash flow $3.8B |
Shareholder returns
How much cash actually flows back to owners - dividends, buybacks, whether the share count truly falls, and whether what is handed back is affordable.
Cash comes back to owners, with a caveat or two in the checks below.
How much goes back to shareholders - and how much leaks out as stock compensation?
→$3.8B returned last year against $994M of stock issued to employees - the returns outweigh the dilution 3.8-to-1.
How fast is your ownership being diluted - or concentrated?
→The count shrank 5.6% last year - buybacks are outrunning stock compensation.
REGN has issued or retired shares - did shareholders end up better off?
Both lines start at 100 in 2011, so the gap between them is what each share gained or lost. Share counts are split-adjusted.
→REGN issued +20% more shares from 2011 to 2025, but revenue per share still rose +2584%. The dilution bought more growth than it cost existing holders.
Why compare buybacks with stock compensation?
A company can trumpet billions in buybacks while quietly issuing nearly as much stock to employees. What matters to you is the net effect: is the share count actually falling? If not, the 'return' is mostly recycling.
How we scored it · 4 of 6 checks passed
| ✓ | Share count isn't climbing | shares down 4.3% over 3 years |
| ✓ | Buybacks outpace the stock issued to staff | $3.3B bought back vs $987M of stock compensation |
| ✓ | What it hands back fits inside its cash flow | 97.8% vs 100.0% |
| ✓ | Meaningful yield to owners (dividends and buybacks) | $3.7B returned, 4.7% of market value |
| – | Reliable payer, never cut | under 2 years of dividend history |
| – | Dividend growing ahead of inflation | under 3 years of dividend history |
Trend analysis
What the market is doing about all of the above. This is price behaviour, not a fact about the business - read it as the market's current opinion, scored on six checks like every other chapter. The market is the S&P 500, measured by the SPY ETF with dividends included, over 3 months (63 trading sessions) and 12 months (252).
The market agrees: the stock is in a healthy uptrend on every horizon.
How is REGN's trend actually behaving right now?
Chart by TradingView
→REGN is in a clear uptrend. The price is above the band where recent trading settled, and that band is still rising underneath it, so the floor keeps moving up. The last two weeks are running ahead of the last month and the price is above where it stood a month ago, so the shorter-term readings back the trend up.
How the trend above is worked out
The trend read comes from the daily Ichimoku picture, a standard trend indicator, translated out of its jargon. It builds a band from the midpoints of the last 9, 26 and 52 sessions' highs and lows - in effect, the range where recent trading has settled - and draws that band 26 sessions into the future. Price above the band is an uptrend, below it a downtrend, inside it no trend. Because the band is drawn forward, the support for the next few weeks is already fixed and a change of its direction can be seen coming. We also compare the last two weeks against the last month, and today's price against where it stood a month ago. None of this says anything about the business; it describes the price only, and it is not advice. Where a check says 'the S&P 500', the comparison is with the SPY ETF including dividends, on the same adjusted basis as the stock's own price: short means 3 months, 63 trading sessions; long means 12 months, 252.

Insider activity
What the people running the company do with their own shares - reported to the SEC within two days, classified so pay-plumbing doesn't masquerade as conviction.
Are the people running it buying or selling with their own money?
→No open-market buying, and $5M of selling across 8 months. Selling alone is a weak signal - much of it is pre-scheduled - but the absence of buying tells you no insider saw the price as a bargain.

Why do the transaction types matter so much?
Most insider filings are not trades: stock grants, option exercises and tax withholding are how executives get paid, and gifts are estate planning. The signal lives in open-market transactions - a buy means an insider chose to spend their own cash on the stock. Sells are murkier: many are pre-scheduled 10b5-1 plans set months in advance. That's why the chart counts only open-market activity, and the table labels every row.
