FDA acceptance of ReadyFlow Autoinjector sNDA puts MannKind in focus

MannKind (MNKD) just got a meaningful catalyst: the FDA accepted its supplemental new drug application for the FUROSCIX ReadyFlow Autoinjector, setting a July 26, 2026 action date that investors will now anchor on.

The ReadyFlow sNDA news has added a clear spark to sentiment, with a 1 month share price return of 17.39 percent lifting MannKind to 5.94 dollars even though year to date share price return remains negative and longer term total shareholder returns point to steadier, more patient gains.

If this kind of pipeline driven rerating appeals to you, it is worth scanning other specialist names in healthcare stocks to see where similar momentum or underappreciated turnarounds might be taking shape.

With shares still trading at a steep discount to analyst and intrinsic value estimates despite accelerating revenue and profit growth, investors now face a key question: is MannKind an overlooked opportunity or is the market already factoring in ReadyFlow driven upside?

Most Popular Narrative: 36.7% Undervalued

With MannKind closing at 5.94 dollars, the most followed narrative pegs fair value meaningfully higher, framing the ReadyFlow catalyst within a broader earnings story.

In order for the above numbers to justify the analysts price target, the company would need to trade at a PE ratio of 68.6x on those 2028 earnings, up from 51.5x today. This future PE is greater than the current PE for the US Biotechs industry at 15.3x.
