Red Flag Alert – An Overlooked Risk at DexCom. Also, Updates on Past Red Flag Alerts.
Just because something isn't listed in the 'risk factors' section of a company's regulatory filings doesn't mean it's not a possible 'risk'...
Take DexCom (DXCM), for example. It's a wildly successful manufacturer of continuous glucose monitors ("CGMs"), which just happens to be headquartered not far from me here in San Diego.
Because of the stock's remarkable rise, DexCom has steamrolled its share of skeptics and short sellers over the years, who felt the company was overstating the potential size of its end market... and understating the potential impact from competition.
As it turns out, even with competition – mostly from Abbott Laboratories (ABT) – it has done exceedingly well.
The reason is obvious: With a CGM, you don't have to stick yourself in the finger several times a day to test your blood sugar. You wear it for a week or two – just set it and forget it.
The bullish angle now is that “you ain’t seen nothing, yet”, especially with this year's start of coverage of CGMs by Medicare for type 2 diabetics who need a certain type of insulin. Type 2 diabetes is the most common and manageable form of diabetes. As DexCom CEO Kevin Sayer said at the company's investor day in June...
That expands our addressable market tremendously.
It's an enormous market of more than 25 million people, including those who don't yet need insulin, but some might say still could benefit from a CGM.
The potential can be seen in DexCom's valuation: While well below its bubble peak, at roughly 80 times forward earnings the stock still reflects investor enthusiasm about its growth potential.
But there's a catch, and it's something that hasn't yet been formally called out by the company as a risk...
It very well may be that type 2 diabetics might not need to wear CGMs… certainly not forever like type 1 diabetics who need to constantly monitor their blood sugar levels. Ditto for a type 2s, whose blood sugar is always out of whack.
The reason for that is the surge in popularity of GLP-1 insulin alternatives, which lower blood sugar to acceptable levels… and seemingly keep them down.
You no doubt have heard of GLP-1s, but mostly because they’ve become maybe even hotter as a weight-loss product. The most popular include Novo Nordisk's (NVO) Ozempic and Eli Lilly's (LLY) Mounjaro.
The trouble is, as good as GLP-1s are they might be too good when it comes to CGMs. That’s because GLP-1s can wind up moving somebody who has been diagnosed as having type 2 diabetes down to pre-diabetic, where it’s debatable whether they need to wear a CGM.
DexCom management has said that GLP-1s and CGMs will be complementary, and they very well may be. Then again, that raises another issue...
Even if a type 2 diabetic starts off wearing a CGM, they might be able to stop after a short while using the GLP-1.
At least that's my interpretation of Sayer's response to a question at an investor conference earlier this year, when he was asked...
There are some GLP-1 drugs that are coming out that obviously, have an impact on type 2. Can you maybe just talk about the impact of GLP-1 and maybe just kind of compare and contrast GLP-1 versus sort of the way you are all attacking the type 2 market?
Sayer responded (emphasis added)...
I think the GLP-1s are marvelous drugs and the results and things we've heard are great. But it's still helpful for these patients to know where they are and what's going on.
Dosing a GLP-1 isn't necessarily easy. Those things can be very difficult for somebody to start up on. So there's certainly use for a DexCom in the beginning.
But as you see the results of your behavior on a GLP-1 by wearing a sensor, it really reinforces the behavior changes that are made. And one of the other things on those slides, and again, I'll go back to it, the cost of taking care of people is up 27% in two years.
He went on to mention how a GLP-1 might "cost a lot more money than being on a CGM," adding (emphasis added)...
I don't know how it all plays out. But I know all the tools are useful, and I know we definitely feel a role and a purpose in here, and that's what we intend to do.
I never believed the business model for type 2 diabetes would be the same. I've always believed it's – we're going to get reimbursed less over time because we're not controlling a pump. It's not a life-or-death decision. But we are providing you information that's important to your health.
► Here's the thing...
When Sayer says that "dosing isn't necessarily easy," he's referring to injections. But oral GLP-1 formulations are starting to hit the market, and CGMs aren't everybody's idea of a good time.
As for cost: The cost of GLP-1s is likely to fall over time.
And then Sayer couldn't have been any clearer when he said that CGMs for type 2 diabetes are a different business model than the company was built on. That's especially true, it would appear, with the onslaught of GLP-1s.
Perhaps most important, he said CGMs are good to use with GLP-1s "in the beginning," not forever. That's significant.
What's more, even Sayer concedes that he doesn't know how all of this will shake out. (Rare to see that kind of candor today.)
On the flipside, betting against Sayer so far has been foolhardy...
In the eight years he has been CEO at DexCom, revenues have grown by more than seven-fold and the stock has grown by more than seven-fold. d. At its peak, the stock was a nearly 10-bagger (with the stock down from the peak, it's currently a “mere” 7-bagger)... That's how quickly the diabetic market has advanced technologically.
As a result, DexCom has a strong balance sheet and excellent free cash flow. And while its CGM is considered best of class, it's also a pure play on a single product and a single disease, which itself can be a risk.
For that very reason, there has been chatter that DexCom could also be a takeover target...
In a June 17 On the Street, I quoted David Kliff of the Diabetic Investor newsletter as saying he believes DexCom would fit well with tech giant Apple (AAPL)...
It fits perfectly into their strategy. There's Apple and Android and Apple could use something like that because it binds people to their platform. And they could charge a small amount of money to do things with the data.
That may be a stretch, but it's icing on the upside if some kind of deal with Apple or someone else ever happened.
If it doesn't, the risk that GLP-1s could impact CGM sales is real... even if it's not spelled out (yet) by the company.
Unlike prior Red Flag Alert, I'm not saying that DexCom is a flat-out "avoid"... but instead a very firm: Buyer beware.
(Edited to correct 80x forward sales; should’ve been forward earnings.🤦)
Speaking of GLP-1s... I recommended Novo Nordisk back in September in the inaugural issue of my Empire Real Wealth newsletter – it's up roughly since then – with the thesis largely tied to GLP-1s for their weight-loss potential.

Moving on, some quick updates on stocks I've red flagged previously...
The most notable: Penumbra (PEN), a medical-devices company with a device that sucks blood clots out of brains. I wrote about it back in mid-June... The stock peaked at the end of the month and has since fallen 27%. It seems the company has had some clinical trial delays.
Also lower are SunRun (RUN), Topgolf Callaway Brands (MODG), ChargePoint (CHPT), and Hannon Armstrong Sustainable Infrastructure Capital (HASI).

Fascinating article. We've seen a lot of articles talking about how some pricey consumer staples stocks might come under pressure due to GLP-1s and biosimilars but not this company. Seems to be far more vulnerable than the multiple might suggest! Good luck & good trading.
