Tipping the Scales

The pharmaceutical world is buzzing, and it’s all thanks to the groundbreaking obesity drugs from Novo Nordisk (NVO) and Eli Lilly (LLY). In my previous newsletter, I delved into the massive potential of these new treatments, and it sparked a flurry of discussions. So, this time, I want to peel back the layers and explore how these advancements affect other companies within the same market.

After all, their emergence creates a paradoxical narrative, a dance of shadows and lumens. These drugs, renowned as the modern panacea for the obesity crisis, have catapulted the companies behind them into unprecedented valuations, making them luminaries in a market awash with investors hungry for the next big thing.

The enthusiasm surrounding these drugs is not unfounded; they are pivotal in treating type 2 diabetes and are seen as the desperately needed solution to the widespread obesity crisis. The groundbreaking medications introduced by Novo Nordisk and Lilly are enabling individuals to lose approximately 15% to 20% of their body weight, with Wall Street anticipating the combined annual sales of these revolutionary drugs to surpass $40 billion by the close of this decade.

However, the shadows of GLP-1s cast a contrasting pallor on companies that burgeoned in tandem with America’s expanding waistlines.

Firms like Insulet (PODD) and Tandem Diabetes Care (TNDM) are witnessing a decline of 40% and 50% in their values this year, respectively.

Similarly, DexCom (DXCM), the frontrunner in glucose monitoring, has experienced a 16% dip, and ResMed (RMD), the stalwart in CPAP machines treating sleep apnea, has seen its stock plummet by 30%. Inspire Medical Systems (INSP) and Madrigal Pharmaceuticals (MDGL) have also encountered significant drops in their shares.

These companies, once the darlings of the medical stock market due to their escalating sales growth, are now facing the brunt of a shifting investor focus. This is because the investment community is envisioning a future with a reduced prevalence of diabetes and sleep apnea and is consequently retracting their stakes in these stocks, leaving companies and investors navigating through a sea of uncertainties.

By early spring, the potential impact of widespread GLP-1 usage became the focal point of strategic discussions at numerous hedge funds. That led to a shift as some started withdrawing from stocks like DexCom and Madrigal, subsequently opting to short-sell these shares. The broader market tuned in this summer.

A case in point is Intuitive Surgical (ISRG), a leader in surgical robotics, which noted during its earnings call that a preference for trying GLP-1s was leading to a deferment in weight-loss surgeries. Although these procedures constitute a minor segment of robotic surgeries, they have been instrumental in driving Intuitive’s growth.

GLP-1s have also affected the demand for insulin injections. Recently, endocrinologists have suggested that GLP-1s could potentially delay the transition to insulin for a significant portion of Type 2 patients. This revelation triggered a recalibration of sales forecasts and stock price targets, with Insulet experiencing a downgrade in both target price and rating.

Meanwhile, the growth prospects of glucose monitor manufacturer DexCom in the Type 2 market remain positive. The integration of glucose monitors with GLP-1s is anticipated to become a prevalent trend among diabetic patients. Despite a temporary rally in DexCom stock, the lingering question remains whether the expanding use of GLP-1s will eventually reduce the demand for glucose monitoring.

Vendors of sleep apnea devices, such as ResMed and Inspire Medical, are also conveying to investors the minimal impact of GLP-1s on their markets. However, the debate continues on the intrinsic link between obesity and sleep apnea and the potential repercussions of GLP-1s on the entire sleep apnea spectrum. As market dynamics continue to shift and the ripple effects of GLP-1s become the focal point of discussions, more and more questions about the future landscape of obesity-associated medtechs arise.

The positive developments in GLP-1s have also cast a shadow over another sector: liver medications.

In June, revelations about Lilly's investigational drug, retatrutide, sent ripples through the sector. The drug not only facilitated a 24% weight reduction in subjects but also significantly diminished fat levels in their livers. This development impacted the stock values of companies like Madrigal Pharmaceuticals, Akero Therapeutics (AKRO), and 89bio (ETNB), pioneers in crafting remedies for the fatty liver condition known as NASH. While it remains to be seen how much these stocks will fall, it’s evident that their decline has already started.

The market is a tumultuous sea of uncertainties, with companies and investors meticulously navigating the evolving dynamics. For the astute investor, the key is to learn how to strike a balance between the old and the new.

The allure of GLP-1s might lead to a reevaluation of the medtech sector’s prospects, but companies like Insulet, ResMed, and Inspire still hold resilience in a GLP-1-dominated landscape.

Ultimately, it’s about understanding the intricate push and pull of shadows and light. The wise investor doesn’t just follow the light; they also understand the shadows, learning to see the opportunities lurking within.

So, delve deep, recalibrate your strategies, and remember, the paradox is not a roadblock; it’s a guidepost to new horizons in pharmaceutical innovation.
