United Therapeutics’ stock (NASDAQ: UTHR) surged 33% on September 2nd after the company announced positive late-stage clinical trial results for Tyvaso (treprostinil) Inhalation Solution in idiopathic pulmonary fibrosis (IPF). The trial met its primary endpoint, and the treatment showed good tolerability with a safety profile consistent with prior Tyvaso studies.
This marks a major expansion opportunity for an already successful therapy. Tyvaso, approved by the FDA in 2009, generated $1.6 billion in sales last year—a 31% year-over-year increase. If approved for the new IPF indication, the drug could add an extra $4-5 billion in peak sales.
Even after the stock’s recent 30% jump, we view UTHR as attractive around $400. The company’s strong fundamentals and a moderate current valuation support further upside, making it a compelling buy despite the rally.
Our constructive view follows a comprehensive review of UTHR’s current valuation alongside its recent operating performance and financial position. Across the key pillars—Growth, Profitability, Financial Stability, and Downturn Resilience—United Therapeutics exhibits very strong operations and balance sheet health, leaving little cause for concern at present levels.
That said, if you want upside with less volatility than a single stock, consider the High Quality Portfolio. It has comfortably outperformed its benchmark—a blend of the S&P 500, Russell, and S&P MidCap indexes—and has delivered returns exceeding 91% since inception.

Putting All The Pieces Together: What It Means For UTHR Stock
In summary, United Therapeutics’ performance across the parameters detailed above is as follows:
• Growth: Strong
• Profitability: Very Strong
• Financial Stability: Very Strong
• Downturn Resilience: Strong
• Overall: Strong
Overall, United Therapeutics has delivered robust results across key financial and operational metrics. While the stock trades at a premium to the index average, the valuation remains moderate given solid revenue growth and strong profitability.
At current levels near $400, UTHR stock trades at 6x trailing revenues—a multiple aligned with its historical average. With positive clinical data that could unlock roughly $5 billion in incremental revenue opportunity, an upward revision to this multiple appears justified.
Of course, our assessment could prove wrong. Investors may be unwilling to pay a higher multiple for UTHR, especially amid rising competitive pressures. The FDA’s approval of Yutrepia in May 2025 introduces new competition that could affect Tyvaso’s pricing power and market position.
Even with these near-term uncertainties, we believe UTHR is a solid opportunity for investors with a 3–5 year horizon, including at prices above $400. The company’s strong operating base and sizable market expansion potential should support long-term value creation for patient investors.
See, there always remains a meaningful risk when investing in a single, or just a handful of stocks. Consider the Trefis High Quality (HQ) Portfolio, which, with a collection of 30 stocks, has a track record of comfortably outperforming the S&P 500 over the last 4-year period. Why is that? As a group, HQ Portfolio stocks provided better returns with less risk versus the benchmark index; less of a roller-coaster ride, as evident in HQ Portfolio performance metrics.
