Is Amphastar Pharmaceuticals (AMPH) overvalued?

At a P/E of 15.5 and a price-to-free-cash-flow of 7.3, Amphastar Pharmaceuticals (AMPH) trades below a two-stage DCF intrinsic value of about $135.10 per share, so at $26.20 the stock looks undervalued (415.7% below estimated intrinsic value). A high multiple is not the same as overvalued: fast-growing, high-quality businesses can deserve a premium. See the general approach in how to tell if a stock is overvalued.

Frequently asked

What is Amphastar Pharmaceuticals's fair value?+

Intrinsiqq's two-stage DCF estimates an intrinsic value of about $135.10 per share for AMPH, projecting its recent free cash flow forward with a growth rate that fades toward a long-run rate and discounting it back to today. Applying a 25% margin of safety gives a more conservative fair-value entry around $101.33. At today's $26.20, that puts the stock about 415.7% below estimated intrinsic value. The result is sensitive to the growth and discount-rate inputs, so it is best to run conservative, base and optimistic cases. You can adjust all of them yourself with the sliders on the DCF tab.

Is Amphastar Pharmaceuticals a high-quality business?+

Amphastar Pharmaceuticals scores 60 out of 100 on Intrinsiqq's quality score, a weighted blend of 8 metrics each scored 0 to 100, which makes it a solid business on these measures. Recent fundamentals include a 15.7% operating margin and a 6.3% return on invested capital. The score weighs revenue and free-cash-flow growth, operating margins, return on invested capital, share-count change, and balance-sheet strength, all computed from SEC filings, not opinion. Because valuation only means something relative to quality, the full metric-by-metric breakdown is on the quality scorecard.

Is Amphastar Pharmaceuticals a good stock to buy right now?+

That depends on valuation and quality together, not either alone. AMPH currently trades below its estimated intrinsic value and scores 60/100 on quality (solid). A cheap price is only a bargain if the business is durable, and a premium can be justified by genuine quality, so the two questions, "is it cheap?" and "is it good?", only make sense side by side. Read the valuation against the quality scorecard, run the DCF on your own assumptions, and decide for yourself. This is analysis from SEC filings, not investment advice.
