Investing in Pigs and Kidneys: Building a $100 Billion Empire and Revolutionizing Organ Transplants


Investing in Pigs and Kidneys: Building a $100 Billion Empire and Revolutionizing Organ Transplants

March 25, 2025 at 4:43 pm

How does one create a $100 billion empire while pioneering an endless supply of transplantable organs that could save millions of lives? The first step is launching a multi-billion-dollar satellite company (SiriusXM – SIRI). The next step? Founding a biotechnology company with nothing more than a high school-level biology education — all in a desperate attempt to save the life of your seven-year-old daughter from a rare heart disease that claims lives within three to five years.

This is the extraordinary path of Martine Rothblatt, CEO and visionary of United Therapeutics Corp. (UTHR), who began this journey 35 years ago.

Transforming Industries: From SiriusXM to Organ Transplants

Few individuals have singlehandedly transformed entire industries. One name that comes to mind is Steve Jobs – who revolutionized consumer electronics and laid the foundation for Apple Inc.’s (AAPL) meteoric rise to a multi-trillion dollar company before he passed away. While Rothblatt and United Therapeutics may not yet be household names, she is undeniably reshaping the healthcare industry and steering it toward a future of unprecedented, life-extending medical advancements.

How can these ambitious, world-changing goals be achieved? A whole aisle of books could be written about Rothblatt’s impressive lifetime accomplishments, but the unique investment opportunity for investors cannot be fully understood without appreciating the person that created United Therapeutics 29 years ago in 1996.

Rothblatt has accomplished more than most humans could in multiple lifetimes – here is a partial sampling of her achievements:

  • Earned a Bachelor of Arts, a Juris Doctor (JD), and Master of Business Administration (MBA) degrees from the University of California, Los Angeles (UCLA).
  • Finished her PhD at The London School of Medicine (Barts)
  • Practiced law at the Covington & Burling law firm representing the television broadcasting industry before the Federal Communications Commission (FCC).
  • Hired by NASA to seek approval from the FCC for NASA systems used to track and relay satellite data.
  • Created the multi-billion-dollar satellite radio company SiriusXM in 1990 with the inspiration of physicist Gerard O’Neill, the same Princeton professor who motivated Amazon CEO, Jeff Bezos to create Blue Origin.
  • Invented the Terasem Movement, an organization with the mission of human life extension that uses cognitive and artificial intelligence software. Terasem’s technology has created a lifelike robot (BINA48), which is modeled after her spouse, Bina Rothblatt.
  • Pioneered EV (electric) helicopter transportation through the company’s Unither Bioelectronics division with the purpose of cutting energy consumption and speeding up organ delivery times.

The United Therapeutics Story

In 1996, while leading SiriusXM, Rothblatt faced every parent’s worst nightmare. Doctors diagnosed her seven-year-old daughter, Jenesis, with Pulmonary Arterial Hypertension (PAH) — a rare, devastating disease with no known cure. Determined to save her daughter, Rothblatt initially funded research grants totaling over a million dollars to a narrow group of five doctors studying the disease. When the scientists failed to find a cure, she took matters into her own hands.

With no formal medical background, she quit SiriusXM, immersed herself in biology, and founded United Therapeutics. Against all odds, armed with her mantra that “persistence leads to omnipotence,” Rothblatt’s relentless pursuit paid off when she discovered a cure. Today, decades later, Jenesis is 42 years old and thriving as a high-profile manager at United Therapeutics.

Addressing the Organ Shortage Crisis

United Therapeutics’ advancements in PAH treatment have allowed patients like Jenesis to live long, productive lives. However, many eventually require organ transplants – the company is already assisting hundreds of patients with lifesaving human lung transplants. Despite some progress, the current organ shortage crisis is staggering:

  • Over 100,000 people are on the national transplant waiting list.
  • More than 92,000 of them need a kidney due to kidney failure or End-Stage Renal Disease (ESRD).

To address the organ shortage, United Therapeutics recently made history last month when the FDA approved the first-ever clinical trial for its UKidney xenotransplantation procedure for kidney failure patients.

The severity of the organ shortage problem is clear-cut if you examine the numbers. In addition to the 92,000 patients on the kidney transplant waitlist mentioned above, there are approximately 500,000 additional ESRD dialysis patients not on the national transplant list. Roughly 10% of these ESRD patients die each year due to dialysis-related complications.

If you combine the wait list population with the dialysis patient population you get to a total of around 600,000 people total. Regrettably, the vast majority of these patients do not receive an organ. In fact, only 27,759 kidney transplants were performed in the U.S. last year. In other words, despite the enormous demand for transplantable organs, less than 5% of the addressable market have actually benefited from a new kidney.

The Future of Organ Transplants: Profitable Pig Potential

How can this massive undersupply of transplants be fixed? One word…pigs. With a very scarce supply of human donors, pigs may hold the key to solving the organ shortage. United Therapeutics has pioneered genetically engineered pig organs (xenotransplantation) by modifying 10 key genes to prevent immune system rejection. As part of the xenotransplantation trial, United Therapeutics has built multiple DPF (designated pathogen free) facilities that house the pigs carrying the gene-modified kidneys.

All of this may sound like science fiction, but the dream of xenotransplantation has already become reality. Just last November, a genetically engineered pig kidney was transplanted into a patient (Towana Looney) under a compassionate use basis granted by the FDA. With its new clinical trial now underway, United Therapeutics is planning to transplant up to 50 patients with modified pig kidneys in the coming months.

And UKidney is just the beginning. United Therapeutics has a deep organ transplant pipeline that extends beyond kidneys into livers, hearts, and lungs (see graphic below). The company is also working on the “holy grail” of transplants – 3D printed organs using the cells of organ recipients to build the tissue structure, which dramatically reduces or eliminates the risk of organ rejection.

If UKidney is successful, United Therapeutics and Martine Rothblatt will be one step closer to realizing the company’s vision of manufacturing an endless supply of transplantable organs.

Investment Opportunity of a Lifetime?

Nothing in life is certain, and there are risks to making any investment, but betting against Martine Rothblatt over the years has been a major losing proposition. From an investment standpoint, the core PAH drug business is trading at an immense discount, and investors are essentially valuing the organ transplant business at $0.

Despite its groundbreaking advancements and tremendous profit growth, United Therapeutics has huge stock price appreciation potential. Here’s why:

Stock is Dirt Cheap: At $317 per share, the stock currently trades at roughly a 50% discount to the trailing S&P 500 Price-Earnings ratio (PE) – 13x P/E vs. 26x index P/E. In other words, the shares should be trading north of $600 (double the price), if United Therapeutics was afforded an “average” company P/E multiple. But United Therapeutics clearly is not an average company.

Over the last two years, the company has grown revenues +48% from $1.9 billion to $2.9 billion and seen earnings explode +64% higher from $15.00 per share to $24.64. The stock becomes even cheaper on a forward P/E multiple (11x P/E) if the company can meet 2025 Wall Street expectations of 15% growth in its EPS to $28.23. Its superior products, execution, and competitive moats should afford the company a significant premium, not a drastic discount. Short-term investors are missing the boat by ignoring the gargantuan market potential for the company.

Is it possible for a $15 billion company to reach a $100 billion market value? This is not difficult to imagine if the company can bring its innovative and revolutionary pipeline products to market and take its current revenue base of almost $3 billion to $16 billion (see graphic below). The company certainly will not reach $16 billion in revenues tomorrow, but if you applied an average market multiple to those projections, and the company were able to maintain its current profit margin profile, a $3,000 per share stock price would be well within reason, equating to a market value well above $100 billion.

Many Irons (Catalysts) in the Fire: United Therapeutics is no one-trick pony. Besides the company’s organ transplant plans, and their core commercial PAH and PH-ILD franchise, which includes, Remodulin, Orenitram, and Adcirca, United Therapeutics has many more irons in the fire that can be catalysts for stock price appreciation over the next 12 – 24 months (see graphic below).

Here is a more detailed description of the drivers:

  • New Markets for Core Drugs: Any biotech or pharmaceutical company is in the business of searching for new markets to sell its products. United Therapeutics has found that in both the IPF (Idiopathic Pulmonary Fibrosis) and PPF (Progressive Pulmonary Fibrosis) markets, which are two different forms of chronic lung disease that are characterized by the gradual scarring and thickening of the lung tissue, which is called fibrosis. These patients can be administered with modified formulations of its existing Tyvaso molecule. The revenue potential is huge if the efficacy data comes in as planned because the pools of patients suffering from these horrible, progressive lung diseases could more than double the size of the present addressable market. Data from the company’s TETON 1 (IPF), TETON 2 (IPF), and TETON PPF studies will be released over the next few years, starting as early as next quarter.
  • Improved Drug Formulation: United Therapeutics is also waiting for groundbreaking data from a drug called Ralinepag, the first once-per-day prostacyclin pill that is an improvement over its existing drugs of Remodulin, Tyvaso, and Orenitram. The company is releasing the Ralinepag data from its ADVANCE OUTCOMES study next year, and if the data proves to be positive, this could represent another multi-billion dollar opportunity for the company and investors.
  • Other Near-Term Catalysts: Although perhaps representing a less meaningful potential from a long-term revenue standpoint, the company’s Centralized Lung Evaluation System (CLES) program is awaiting an FDA decision this year – CLES is designed to expand the supply of donor lungs. Last, but not least, data from United Therapeutics’ microliverELAP study represents another sizeable revenue opportunity for liver transplants.

Fly in the Ointment: Failing Capital Allocation Grade

United Therapeutics deserves an A+ grade for developing the critical, world-class therapeutics that serve the PAH and PH-ILD market and the massive potential pipeline in xenotransplantation and alternative organ platforms. However, the company receives a failing grade for the implementation of its capital allocation strategy. United Therapeutics holds an excessively bloated cash surplus on its balance sheet, which has exploded higher from $1.0 billion in 2015 to $4.7 billion in 2024.

Sadly, the problem is only getting worse, as the company is on pace to add more than $1 billion more to the cash balance this year, and in subsequent years. This is woefully inefficient and becoming an alarmingly growing percentage (approximately 30% currently) of the company’s market value. To put this issue into perspective, investors should consider the company has enough cash on its balance sheet to effectively fund two decades of capital expenditure requirements. Profitable companies in United Therapeutics’ hand-selected proxy peer group hold a much more responsible amount of cash, representing about 4% of their market values.

If you had $100k of annual spending requirements, would you negligently place $2 million dollars in a low-single-digit yielding checking account or multi-year CD at your bank, when you could responsibly earn a 10% or higher return by paying down credit card debt? This is what United Therapeutics is doing. The company is essentially burning shareholder money by letting cash sit idly on its balance sheet earning a pittance when it could be earning significantly more. Why invest in government Treasuries when you could invest in your own company, compounding at rates greater than 10%?

The solution is clear. Implement a meaningful share repurchase program that is immediately EPS-accretive with the company’s bloated mountain of cash and bring down to responsible levels that are consistent with profitable growth peers. And rather than limiting your share repurchase to a one-time accelerated stock repurchase (ASR) program, expand the buyback to be more open ended on top of immediate purchases.  This strategy provides the company with the flexibility to opportunistically purchase shares at a discount when the share price is depressed – like now, when shares are down -24% over the last five months.

Unfortunately, my message appears to be falling on deaf ears. I was hoping to gain clarity through communications with the company along with a letter sent to management and the board of directors. In my letter, I attempted to remind management of the importance of upholding its rigorous corporate governance standards and exercise its fiduciary duty when it comes to the company’s allocation strategy. However, regrettably, up to this point, there has been no indication to the market or me that there is any urgency to take advantage of the massively discounted United Therapeutics share price that exists today.

Investors Should Not Miss the Forest for the Trees

Although the company receives a failing capital allocation grade from my perspective, investors should not miss the forest from the trees. United Therapeutics’ share price is currently trading at a gigantic discount, yet it boasts unparalleled profitability and a groundbreaking organ transplant pipeline.

This lack of appreciation for the shares is surprising given how wildly profitable the company is and its tremendous long-term track record of success. But the company is not sitting on its hands – United Therapeutics has ambitious plans to expand its current annual revenue base by more than five-fold from $3 billion to $16 billion due to full cupboard of pipeline products.

With Martine Rothblatt at the helm—a visionary with a track record rivaling Steve Jobs—the company is poised to revolutionize healthcare. The world is a better place due to Martine Rothblatt, and your portfolio will be a better place with an investment in United Therapeutics.
