Alright boys and girls, men and women, degenerates, regards, and to all who’ve lost all but a single brain cell, Ima bout to drop a bombass DD so fat it’ll make your last L on 0DTEs look like an angelic contribution to charity. In this not so short wall of text written by me fueled by an overdose on caffeine and autism so bad I got a participation trophy for showing up to my Wendy’s orientation, I am going to tell you why there’s a high probability that the company Tandem Diabetes is going to get privately acquired, or trade at such a high multiple in the next few years it’ll make your crypto plays look like a used napkin NFT.
Some additional context for folks who’ve got the memory of a goldfish, or were living under a rock for the past few years, if you thought Tandem was going to go private from that one reddit post when the stock price was hovering around in the $40s, it might actually happen now given how the stock is trading.
Placing a $825k bet on Tandem Diabetes getting privately bought out or mooning. Good luck to me and folks holding this. If you’re a scared lil bitch like me and would like to de-risk from any AI related investments, this might be a worthwhile investment.

**TL;DR for the ADHD regards:**
$TNDM is trading like it’s a dying hardware company when it’s quietly becoming a recurring-revenue diabetes SaaS machine. Wall Street sees temporary PayGo transition pain, but the reality is Tandem is converting pump users into long-term cash-flow annuities while the market panic dumps the stock near 1x revenue.
Meanwhile:
* They’re about to launch a tubeless Mobi pump to directly fight Omnipod
* Their algorithm is already considered one of the best by actual users
* Type 2 diabetes is a gigantic untapped market
* EBITDA is inflecting positive
* SG&A bloat makes them PE bait
* At \~$1B market cap, this thing is small enough to get privately acquired
So either:
1. Tandem executes, margins explode, and the stock rerates violently higher
2. The stock stays stupidly cheap and some PE/strategic buyer scoops it for a fat premium
Basically you’re paying liquidation-tier pricing for a company that could become a recurring cash-flow monster in one of the stickiest medical markets on Earth.
Risk? FDA delays, Medicaid clownshow, GLP-1s, execution issues.
Reward? Potential 10x bagger or buyout at a premium while everyone’s distracted losing rent money
**So, what the fuck is a Tandem Diabetes?**
https://preview.redd.it/a61w4udzyw3h1.jpg?width=220&format=pjpg&auto=webp&s=3e58746ec41fa5ce7ecca51c6b1a6327f296f8b2
Tandem Diabetes Care ($TNDM) is a medtech company that makes insulin pumps and automated insulin-delivery systems for people specifically with Type 1 diabetics and a small subset of Type 2 diabetics, competing in the fast-growing “artificial pancreas” market where pumps integrate with continuous glucose monitors (CGMs) to automatically adjust insulin delivery throughout the day. Its core products are the t:slim X2 and the Mobi pump, powered by their Control-IQ algorithm.
Most of you probably won’t read this, but here’s a quick tl;dr to catch you up on Tandem recently.
* Tandem is transitioning patients from DME to the Pay-As-You-Go (PayGo) model, effectively multiplying sales per patient by more than double. Once a patient is in the ecosystem, they generate multi-year recurring revenue (infusion sets, cartridges, upgrades). This is closer to SaaS than hardware in terms of pricing and revenue.
* Tandem already guided to a positive EBITDA trajectory (\~5-6% adjusted EBITDA 2026, increasing from here). After transitioning a majority of patients to PayGo combined with an optimistic outlook, Tandem could be cash-flow positive as soon as 2027.
* Earns their current market cap in revenue alone (2026 projected revenue of $1.075B vs market cap of $1.00B - $1.1B). At a $1B revenue minimum, Tandem is cheap enough for a PE fund or strategic buyer to actually swallow without regulatory nightmares. At current multiples, a 30-50% acquisition premium isn’t outrageous.
* In the current insulin pump market, Insulet ($PODD) is the only real competitor to Tandem. Omnipod (Insulet’s insulin pump) offers tubeless, while Tandem offers the superior insulin pump algorithm. Tandem’s most recent earnings call shows that they are on track to have a tubeless product next year that competes directly with Omnipod. Combine this with the untapped market of Type 2 diabetes (which is around 20x the size of Type 1 diabetics) and Tandem may begin to expand aggressively with new patients.
**What the fuck happened to the stock?**
https://preview.redd.it/ovd6etdzyw3h1.jpg?width=374&format=pjpg&auto=webp&s=541dfc3d13bf263300bbc68018dc1ce1f95dd8b6
Tandem reported fantastic 2025Q3 and 2025Q4 earnings with record revenue, improving margins, and first real signs of operating leverage. Additionally, Tandem reported record 2026Q1 earnings numbers, and retained their guidance into 2026, yet stock traded -15% the day after 2026Q1 earnings.
One key factor that may have contributed to the stock price dropping is that Tandem has been migrating new patients onto its newer Pay-To-Go (PayGo)/pharmacy-style model instead of the older upfront pump sales model through DME channels. Long term, this is the healthier business model since it lowers upfront patient costs, improves accessibility, and creates more recurring-style revenue. The problem is that transitions like this tend to completely screw up near-term financial optics, which was reflected in the 2026Q1 report on their 2026 guidance (\~75M-85M revenue headwind).
Something interesting to note is that several analysts actually re-rated the stock higher to around high $20s after 2025Q3 + Q4 earnings (this was also when 2026 guidance was provided). It seemed that this was reflected after seeing margins improve, slowing cash burn, and revenue finally surpassing the $1B mark.

You see all those yellow dots? All but one represents a price target increase. Apologies for using the Yahoo chart, it was the best I could find. I’m usually skeptical of analyst target upgrades since they don’t carry much weight on their own. But seeing this many upward revisions in a relatively low-volume stock that doesn’t normally get this kind of attention is interesting to see.
**Tandem’s new PayGo model**
Tandem is fundamentally changing how insulin pumps are sold and reimbursed, not the underlying economics per patient (Pulled from slide deck).
https://preview.redd.it/vk7c3vdzyw3h1.png?width=1151&format=png&auto=webp&s=564a1b9b3e869c3b702dbadbd18030c37edfe4cf
Tandem is actively shifting from a traditional durable medical equipment (DME) model toward the pharmacy-channel and PayGo distribution, where pumps and supplies are increasingly accessed through pharmacy benefits and installment-style structures rather than a single upfront device purchase.
Historically, starting pump therapy looked like this:
1. Patient gets approved through insurance (heavy prior authorization process)
2. Tandem sells a pump as a **large upfront durable medical device purchase**
3. Insurance reimburses most of the cost at the point of sale
4. Patient enters ecosystem and generates recurring consumable revenue:
* infusion sets
* cartridges
* pump upgrades approximately every 4 years
# This type of revenue profile is front-loaded, highly dependent on insurance approval timing, and relies heavily on the number of new patients starting in a given quarter.
Under the new PayGo structure:
1. Patients are onboarded through **pharmacy benefits instead of purely DME workflows**
2. Upfront cost barrier is significantly reduced or eliminated
3. Instead of a large lump-sum device sale, revenue is spread over time (installments/supply billing/pharmacy reimbursement flow)
4. Patients still receive the same pump and access to the same ecosystems (Control-IQ, Mobi, etc.)
Now, with the new PayGo model on the pharmacy channel, patients are instead onboarded with lower friction and lower initial cost burden, effectively turning Tandem’s revenue profile into that of a SAAS company.
This might seem like customers are paying more in the long term given how revenue is doubled for the new PayGo model, however the important part is that patients aren’t paying more in the long term under PayGo because insulin pump economics are primarily driven by insurance reimbursement, not direct out-of-pocket spending.
PayGo doesn’t raise the underlying price of care. It changes how and when insurers pay for it, shifting costs from a large upfront durable medical equipment purchase to smaller, ongoing pharmacy or supply reimbursements. Patients still face similar copays and deductible caps regardless of model, so their personal financial exposure remains largely unchanged. The higher revenue comes from more patients successfully entering the system and staying in it longer, not from each patient paying significantly more.

* According to Tandem’s 2026 guidance, gross margin is hovering around 55-60%, targeting 65% in the long term. For now, let’s assume their gross margin is 60% to be conservative
* Tandem’s operating expense for both 2024 and 2025 is around $588M and $733M. The OpEx for 2025 was \~$95M higher due to litigation + acquisition. Using Tandem’s 2026 EBITDA guidance, we can predict that their OpEx for 2026 will hover around the $550M area. For the next few years, let us assume their OpEx peaks at $700M per year.
* Assume Tandem does NOT acquire any new patients in the next few years, and retains all of their existing patients (0% new patient growth YoY).
Using their recent 2025Q4 slide deck for some starting numbers, we can project what their revenue + net profit would APPROXIMATELY look like across the board given the proportion of folks on DME/PayGo. The yellow represents what Tandem is currently at.

One of the growing pain points in Tandem’s financials is their Operating Expenses, specifically their SG&A. Digging into their past financials, we see that nearly more than 2/3rds of their expenses comes from Selling, General, and Administrative (Surprisingly their research expenses are consistent across 2024 + 2025).
https://preview.redd.it/riy6rcezyw3h1.png?width=1743&format=png&auto=webp&s=4656a99e15b8eac4bdcf497a1d019058833337e2
If there was an opportunity for a PE firm to acquire Tandem, any reduction in Operating Expenses (which are PE’s specialty) is money pocketed as profit. From another angle, Operating Expenses can also be massively cut if Tandem is acquired by another company by combining their administration costs together, effectively stopping the Operating Expenses from eating away at any potential Net Income.
**From a valuation perspective, if Tandem successfully migrated all patients to PayGo, they would generate an approximately $500M in net profit, equating to roughly $7.50 in earnings per share (EPS). At a share price of around $15.00 at the time of writing, the stock would be trading at a price-to-earnings (P/E) ratio of 2.** For context, competitor Insulet (A competitor that received a private acquisition offer from Dexcom in 2022) currently trades at a P/E ratio of roughly 35, even after experiencing a nearly 50% decline in market capitalization. Insulet also maintains an approximate $10B market cap despite having only around 50% more patients than Tandem, whose market capitalization currently sits around $1B. Baseline, this suggests a potential minimum 10-20x upside in the stock over the next few years, with the possibility of an even higher valuation multiple if you’re bullish on the upcoming events presented later below.
**Tandem’s Existing Competitors**
According to T1D research, the most common insulin pumps as of 2025 in order are the Tandem t:slim X2, Insulet Omnipod 5, and the Medtronic MiniMed 780G. I’ve been told by my Type 1 diabetic friends that Medtronic is complete dogshit so for simplicity we will discuss the t:slim vs Omnipod 5. After reading countless number of subreddit posts in r/Type1Diabetes and r/diabetes_t1, here are my key gatherings.
https://preview.redd.it/c2dg8q32zw3h1.png?width=1099&format=png&auto=webp&s=11f47c8d4de3306ee03cd366ea79437ab706a8da
The general consensus is that t:slim X2 offers superior performance and control of your insulin, while the Omnipod trades the performance and control for simplicity and freedom through tubeless. After listening in on the last earnings call, Tandem plans to file their 501(k) new Mobi Tubeless model by 2026Q2. This is going to be Tandem’s very first tubeless pump offering. Combine this with their existing superior algorithm and Tandem may begin to take market share from Insulet, arguably the only other major competitor in this space.
**T1 vs T2**
One thing that stood out to me was the insulin pump opportunity in Type 2 diabetes. Pumps are not exclusively for Type 1 diabetics. In severe Type 2 cases requiring intensive insulin therapy, pumps can be prescribed when multiple daily injections are no longer enough to maintain glycemic control.
While Type 2 diabetes is roughly 20x larger than the Type 1 population, only an estimated 5-10% of Type 2 patients are realistic pump candidates. Even so, that still creates an addressable market potentially equal to roughly 1-2x the size of the entire Type 1 pump market. Below is a picture of Tandem’s mobi tubeless product.
https://preview.redd.it/eg03dcezyw3h1.png?width=640&format=png&auto=webp&s=df5f1b7f72dfd7410b720eab183d5ed3288f7b2a
Many Type 2 patients are likely to prioritize convenience, simplicity, and low-friction device management over maximizing advanced automation features (Basically Type 2 diabetics are LAZY). Insulet currently appears to have the advantage because Omnipod is already FDA-cleared for Type 2 use, and its tubeless, pharmacy-friendly system aligns well with what many Type 2 patients want. Tandem has historically focused more on intensive Type 1 users with better insulin algorithms. If Tandem successfully launches and scales its Mobi tubeless platform, Tandem could capture a substantial share of the Type 2 market, nearly matching or doubling its current user base of the Type 1 market. A successful Mobi rollout would allow Tandem to directly compete with Omnipod in the highest-growth segment of the pump market while leveraging Tandem’s superior algorithm. Given the size of the Type 2 market, even modest market share gains could meaningfully accelerate Tandem’s revenue growth and expand its long-term earnings potential.
At the current state, per last earnings call, Tandem emphasized pharmacy distribution, Type 2 expansion, and the upcoming Mobi Tubeless system, which is expected to be submitted for FDA clearance in Q2 2026. Management also highlighted future growth drivers including Android compatibility, pharmacy expansion, and broader Type 2 adoption. We should be expecting to see this potentially good news around the same time a huge proportion of patients migrated to PayGo.
**Cautionary Bear Situations**
https://preview.redd.it/u1bofvdzyw3h1.jpg?width=165&format=pjpg&auto=webp&s=e5664f205975e28bd3341bff5ed9fd18121d40d6
Now this wouldn’t be a proper DD without listing the possible bear cases that could potentially come to happen, so here is a list of things in detail I researched and thought of for folks who practice proper risk management in their investment.
**Medicaid is a complete shitshow**
One major bear case for Tandem Diabetes Care is the uncertainty surrounding Medicaid and broader insurance reimbursement for insulin pumps. Coverage rules vary heavily by state and often require extensive prior authorization, specialist documentation, or proof of insulin dependence before approval, creating friction for new patient onboarding. This risk becomes more important as Tandem pushes into the much larger Type 2 market, where many patients rely on government-backed insurance and lower-cost access pathways. Even if demand for automated insulin delivery grows, reimbursement bottlenecks could slow adoption, increase SG&A costs tied to payer support, and pressure recurring supply revenue if states tighten coverage standards amid rising healthcare spending.
**Unomedical, the supplier of infusion sets to Tandem, receives FDA warning letters**
A major operational risk for Tandem is its reliance on Convatec subsidiary Unomedical, which manufactures infusion sets used with Tandem pumps. In January 2026, the FDA issued a warning letter to Unomedical’s Reynosa facility citing quality-system failures, complaint handling deficiencies, and issues tied to prior infusion set recalls. While Convatec stated the warning letter did not restrict production, any escalation could disrupt supply availability, delay shipments, or hurt customer retention if shortages worsen. Because Tandem’s business model depends heavily on recurring infusion set usage, prolonged supply-chain instability could directly impact both revenue growth and investor confidence. On the flip side, if Tandem is able to push out their mobi tubeless model, these issues would disappear (since tubeless doesn’t require any infusion sets)
**Increasing Operating Expenses (specifically research) for Tandem’s new mobi tubeless model**
Tandem’s operating expenses, especially R&D and commercialization costs will continue rising as it develops and scales the Mobi Tubeless platform. Competing directly with Insulet in tubeless insulin delivery requires substantial investment in hardware design, automation software, manufacturing scale-up, clinical trials, and regulatory compliance. Tandem is also simultaneously supporting its legacy t:slim ecosystem while expanding pharmacy distribution and Type 2 commercialization, which may delay operating leverage. If revenue growth fails to outpace these investments, profitability improvements could take significantly longer than bullish investors expect.
**FDA clearance on the mobi tubeless model**
Tandem’s long-term growth thesis depends heavily on successful FDA clearance and commercialization of its upcoming Mobi Tubeless system, making regulatory execution a key risk. Insulin delivery systems face intense FDA scrutiny because software or delivery failures can create life-threatening consequences, and Tandem has previously experienced recalls tied to pump software and app connectivity issues. Any delays, additional clinical requirements, or post-market safety concerns involving Mobi Tubeless could significantly slow Tandem’s ability to compete against Insulet’s already-established Omnipod platform. Since much of the bullish valuation narrative depends on future execution rather than current earnings, regulatory setbacks could materially impact market sentiment and future growth expectations.
**Failure to capture the Type 2 market and the threat of GLP-1**
The biggest strategic bear case is that Tandem fails to meaningfully penetrate the Type 2 diabetes market while GLP-1 drugs reduce long-term insulin demand growth. Although Type 2 represents a massive opportunity, adoption is far from guaranteed because many patients prefer simpler, lower-friction treatment options managed through primary care rather than specialist pump therapy. Insulet currently appears better positioned due to its tubeless Omnipod system, pharmacy distribution model, and existing FDA clearance for Type 2 patients. At the same time, GLP-1 medications are improving glucose control and reducing insulin intensity for some patients, potentially shrinking the future pool of potential insulin pump patients. If Tandem struggles to differentiate its ecosystem or scale Type 2 adoption efficiently, investors betting on a large future market expansion may be disappointed.
**So where does that lead us, and what do I look out for?**
I believe Tandem really only has two choices: Either the stock goes up, or stock goes down enough that it’ll get privately bought out (The cushion you get from owning this stock). If you plan to invest in Tandem, here are three things you should keep an eye out for are the following in my opinion.
* How fast is Tandem migrating users from DME to PayGo (This is the core revenue generating strategy)
* What is the timeline of the Mobi Tubeless? (FDA is a pain in the ass sometimes and can delay)
* Is the Operating Expenses increasing or flatlining?
If all of these go somewhat smoothly, expect Tandem to be an insane cash generating machine for a biotech company.
*As always, not financial advice. I’m just sharing my personal opinions/research for discussion and entertainment purposes. Always do your own due diligence and consult a licensed financial professional before making investment decisions.*
