Insulet (PODD)

Insulin delivery company Insulet Corporation (NASDAQ:PODD) beat Wall Street’s revenue expectations in Q3 CY2025, with sales up 29.9% year on year to $706.3 million. On top of that, next quarter’s revenue guidance ($767.8 million at the midpoint) was surprisingly good and 5.1% above what analysts were expecting. Its non-GAAP profit of $1.24 per share was 8.1% above analysts’ consensus estimates.

Company Overview

Revolutionizing diabetes care with its tubeless "Pod" technology, Insulet (NASDAQ:PODD) develops and manufactures innovative insulin delivery systems for people with diabetes, primarily through its Omnipod product line.

Patient monitoring companies within the healthcare equipment industry offer devices and technologies that track chronic conditions and support real-time health management, such as continuous glucose monitors (CGMs) and sleep apnea machines. These businesses benefit from recurring revenue from consumables and software subscriptions tied to device sales (razor, razor blade model). The rising prevalence of chronic diseases like diabetes and respiratory disorders due to an aging population as well as growing adoption of digitization are good for the industry. However, these companies face challenges from high R&D costs and reliance on regulatory approvals. Looking ahead, the sector is positioned for growth due to tailwinds like the rising burden of chronic diseases from an aging population, the shift toward value-based care, and increased adoption of digital health solutions. Innovations in AI and machine learning are expected to enhance device accuracy and functionality, improving patient outcomes and driving demand. However, there are headwinds such as pricing pressures as healthcare costs are a key focus, especially in the US. An evolving regulatory landscape and competition from more tech-forward new entrants could present additional challenges.

Insulet's main competitors in the insulin pump market include Medtronic's MiniMed division (NYSE:MDT) and Tandem Diabetes Care (NASDAQ:TNDM), both of which offer traditional tubed insulin pump systems.

Larger companies benefit from economies of scale, where fixed costs like infrastructure, technology, and administration are spread over a higher volume of goods or services, reducing the cost per unit. Scale can also lead to bargaining power with suppliers, greater brand recognition, and more investment firepower. A virtuous cycle can ensue if a scaled company plays its cards right.

With $2.52 billion in revenue over the past 12 months, Insulet has decent scale. This is important as it gives the company more leverage in a heavily regulated, competitive environment that is complex and resource-intensive.

A company’s long-term sales performance is one signal of its overall quality. Any business can put up a good quarter or two, but many enduring ones grow for years. Thankfully, Insulet’s 23.8% annualized revenue growth over the last five years was excellent. Its growth surpassed the average healthcare company and shows its offerings resonate with customers, a great starting point for our analysis.

Long-term growth is the most important, but within healthcare, a half-decade historical view may miss new innovations or demand cycles. Insulet’s annualized revenue growth of 27.3% over the last two years is above its five-year trend, suggesting its demand was strong and recently accelerated.

We can dig further into the company’s sales dynamics by analyzing its constant currency revenue, which excludes currency movements that are outside their control and not indicative of demand. Over the last two years, its constant currency sales averaged 26.8% year-on-year growth. Because this number aligns with its normal revenue growth, we can see that Insulet has properly hedged its foreign currency exposure.

This quarter, Insulet reported robust year-on-year revenue growth of 29.9%, and its $706.3 million of revenue topped Wall Street estimates by 3.9%. Company management is currently guiding for a 28.5% year-on-year increase in sales next quarter.

Looking further ahead, sell-side analysts expect revenue to grow 18.4% over the next 12 months, a deceleration versus the last two years. Despite the slowdown, this projection is noteworthy and implies the market is baking in success for its products and services.

Insulet has done a decent job managing its cost base over the last five years. The company has produced an average operating margin of 12.1%, higher than the broader healthcare sector.

Looking at the trend in its profitability, Insulet’s operating margin rose by 10.7 percentage points over the last five years, as its sales growth gave it operating leverage. Zooming in on its more recent performance, we can see the company’s trajectory is intact as its margin has also increased by 8.5 percentage points on a two-year basis. These data points are very encouraging and show momentum is on its side.

This quarter, Insulet generated an operating margin profit margin of 16.7%, in line with the same quarter last year. This indicates the company’s overall cost structure has been relatively stable.

Revenue trends explain a company’s historical growth, but the long-term change in earnings per share (EPS) points to the profitability of that growth – for example, a company could inflate its sales through excessive spending on advertising and promotions.

Insulet’s EPS grew at an astounding 59.9% compounded annual growth rate over the last five years, higher than its 23.8% annualized revenue growth. This tells us the company became more profitable on a per-share basis as it expanded.

We can take a deeper look into Insulet’s earnings to better understand the drivers of its performance. As we mentioned earlier, Insulet’s operating margin was flat this quarter but expanded by 10.7 percentage points over the last five years. This was the most relevant factor (aside from the revenue impact) behind its higher earnings; interest expenses and taxes can also affect EPS but don’t tell us as much about a company’s fundamentals.

In Q3, Insulet reported adjusted EPS of $1.24, up from $0.90 in the same quarter last year. This print beat analysts’ estimates by 8.1%. Over the next 12 months, Wall Street expects Insulet’s full-year EPS of $4.58 to grow 18.2%.

Although earnings are undoubtedly valuable for assessing company performance, we believe cash is king because you can’t use accounting profits to pay the bills.

Insulet has shown decent cash profitability, giving it some flexibility to reinvest or return capital to investors. The company’s free cash flow margin averaged 5.7% over the last five years, slightly better than the broader healthcare sector.

Taking a step back, we can see that Insulet’s margin expanded by 32.6 percentage points during that time. This is encouraging, and we can see it became a less capital-intensive business because its free cash flow profitability rose more than its operating profitability.

Insulet’s free cash flow clocked in at $100.1 million in Q3, equivalent to a 14.2% margin. This cash profitability was in line with the comparable period last year and above its five-year average.

EPS and free cash flow tell us whether a company was profitable while growing its revenue. But was it capital-efficient? Enter ROIC, a metric showing how much operating profit a company generates relative to the money it has raised (debt and equity).

Insulet’s five-year average ROIC was 13.5%, higher than most healthcare businesses. This illustrates its management team’s ability to invest in profitable growth opportunities and generate value for shareholders.

We like to invest in businesses with high returns, but the trend in a company’s ROIC is what often surprises the market and moves the stock price. Insulet’s ROIC has increased significantly over the last few years. This is a great sign when paired with its already strong returns. It could suggest its competitive advantage or profitable growth opportunities are expanding.

Insulet reported $757.4 million of cash and $1.01 billion of debt on its balance sheet in the most recent quarter. As investors in high-quality companies, we primarily focus on two things: 1) that a company’s debt level isn’t too high and 2) that its interest payments are not excessively burdening the business.

With $602.2 million of EBITDA over the last 12 months, we view Insulet’s 0.4× net-debt-to-EBITDA ratio as safe. We also see its $13.8 million of annual interest expenses as appropriate. The company’s profits give it plenty of breathing room, allowing it to continue investing in growth initiatives.

We were impressed by how significantly Insulet blew past analysts’ constant currency revenue expectations this quarter. We were also glad its revenue guidance for next quarter trumped Wall Street’s estimates. Zooming out, we think this was a solid print. The stock remained flat at $314.01 immediately after reporting.

The latest quarterly earnings matters, sure, but we actually think longer-term fundamentals and valuation matter more. Investors should consider all these pieces before deciding whether or not to invest in Insulet.

There is a lot to like about Insulet. First, the company’s revenue growth was impressive over the last five years, and analysts believe it can continue growing at these levels. On top of that, its constant currency growth has been marvelous, and its rising cash profitability gives it more optionality.

Insulet’s P/E ratio based on the next 12 months is 53.6x. Expectations are high given its premium multiple, but we’ll happily own Insulet as its fundamentals shine bright. We’re in the camp that investments like this should be held for at least three to five years to negate the short-term price volatility that can come with high valuations.

Wall Street analysts have a consensus one-year price target of $378.21 on the company (compared to the current share price of $307.67).
