MannKind (MNKD) Pipeline Expansion: Assessing Valuation After New United Therapeutics Collaboration

Kshitija Bhandaru

If you have been watching MannKind (MNKD), the company just shook things up. MannKind announced it is expanding its global license and collaboration agreement with United Therapeutics, bringing an additional development product under its wing. This means MannKind will be using its proprietary Technosphere platform to formulate a new investigational molecule, with the potential to earn $5 million upfront, up to $35 million in milestone payments, and 10% royalties if the product reaches market. For investors, this is not just a routine business update; it signals momentum behind MannKind’s technology and opens new doors for its pipeline.

This development comes at an intriguing time for MannKind shareholders. Over the past month, shares have gained an impressive 58%, building on strong three-year and five-year returns. At the same time, the stock is still down roughly 9% over the past year, and returns year-to-date remain in the red. This blend of recent upside and longer-term volatility makes the current moment feel like a potential turning point, especially as investors react to both the license expansion and a spate of upcoming conference appearances by MannKind’s leadership.

The question now is simple: does the recent jump reflect MannKind’s true worth, or is the market already baking in more future growth than is justified?

Most Popular Narrative: 43.4% Undervalued

The most widely followed narrative sees MannKind as significantly undervalued, implying strong upside if expectations are met in the coming years. It draws on detailed projections for revenue, margins, and market expansion to support this view.

Afrezza's continued double-digit prescription growth, international expansion efforts, upcoming pediatric indication launch, and a broadened salesforce footprint are set to accelerate market penetration amid a rising global diabetes burden and an aging population. These factors directly support revenue and earnings growth. Multiple late-stage pipeline programs (inhaled clofazimine for NTM and nintedanib DPI for IPF) are progressing toward key regulatory and clinical milestones. They benefit from expedited pathways and growing unmet need in chronic respiratory diseases, with the potential to significantly diversify and expand future revenues.

What is powering this “undervalued” thesis? The secret sauce is an ambitious set of growth assumptions for MannKind’s revenue, profit margin, and pipeline success. This narrative suggests plenty of fuel for a rally, but the real drivers may surprise you. Curious to see which bold financial projections are behind this target? The numbers are more aggressive than you might think, so get ready to unpack the core ingredients of this high-stakes valuation case.

Result: Fair Value of $9.83 (UNDERVALUED)

However, MannKind’s reliance on key products and ongoing challenges in expanding Afrezza’s market share could slow growth if these hurdles persist.

Another View: How MNKD Stacks Up on Earnings
