MAIN has strong fundamentals and a competitive advantage in issuing shares at a premium, but the total dividend yield is overstated due to unsustainable supplemental payments, and weakening credit quality threatens the valuation premium.

Main Street Capital is one of the greatest monthly dividend paying stocks of all time for a multitude of reasons. However, like most BDC's in the last year, they have really struggled, especially compared to the broader market.

If we just look at the performance versus the S&P 500, we're talking about underperformance of around 30% at least on a price return basis. If we do look at this on a total return basis, it's a little bit of a different story, but they're still significantly underperforming.

This is true whether we look at it over the last year or year to date.

So, who is Main Street Capital? Well, again, we stated earlier they're BDC. Basically, they give public market investors a way to invest in private businesses. So for Main Street Capital, basically they lend capital to smaller private companies.

They sometimes own a stake alongside with the loan and they'll manage investments for outside investors.

However, historically, Main Street Capital has been different. Over the last 10 years, the share price has climbed by 64%. And here's what's really interesting. Look at the total returns over the past decade.

It's quite impressive for Main Street Capital. For a large majority of the last decade, they were actually significantly outperforming the S&P 500 until we saw the large pullback here in 2026.

And now overall, the performance has been pretty much on par with the S&P 500.

Now, why has Main Street Capital performed so well? Well, overall, it's due to a multitude of reasons, but look at the quality of this BDC compared to their peers. If we just zoom in right here is Main Street Capital.

There's a couple of things that we need to point out. To start, we can see in the BDC database, they have the strongest base dividend coverage. The dividend is very well covered, but keep in mind, we're talking about base dividend coverage, not total dividend coverage.

We can see this is a BDC that historically has been growing dividends. This is a BDC, and this is very important, that has low variable rate debt. And perhaps most importantly, it's an internally management BDC, meaning management is aligned with shareholders.

And historically, they've actually seen positive tangible value per share growth. So intrinsic value is growing. This is something they highlight in their investor presentation.

Long-term focus on delivering our shareholders sustainable growth in net asset value and recurring dividends per share.

Maine has never decreased its monthly dividend rate. An incredible accomplishment for BDC. But this is also where I have to start to point out one of the concerns I personally have with Main Street Capital, and it's something you need to be aware of as well.

When we look at the starting yield for BDC's, typically on most softwares, we only see the headline yield. I know I've highlighted this before, but it's so important. This is the yield.

It's roughly 7.7 7.8% for Main Street Capital. That's not a good representation of the actual yield you'll get.

If we zoom in, let's take a look at Main Street Capital. What we can see is the base dividend is actually 5.7% and the total dividend is 7.8%. Now, what's the actual difference between the two?

Well, the base dividend is here in the gray. It's what you theoretically should be expecting to always get, while the green is the supplemental dividend. So, when you add supplemental with the monthly base dividends, you get your total yield.

So, we can see they've been paying a lot of supplemental dividends as of late, and they make it their goal to do exactly that whenever they can.

However, here's the issue. Yes, we can see base dividend coverage, the 5.7% yield, the base dividends is well covered, 133% coverage. Here's the issue with the total dividend yield.

Right now, if we look at the recent outlook management gave us from the earnings report, they stated, "We expect third quarter of 2026 distributable net investment income before tax of at least 97 cents per share." 97 cents per share.

Remember that number for a moment. Take a look back here on Seeking Alpha. We can see the total amount they're paying out in dividends forward looking is about $4.38. Now, if you take that number and basically do some napkin math, what does that turn into?

Well, if we divide 438 by around 4, it equals $19 per share. About $110, 1.095. That's how much they'd have to generate each quarter in distributable net investment income for the total yield to be sustainable.

So management is literally telling us right now the supplemental dividend they're currently paying out. The supplemental dividend they've paid out over the last few months right now is not sustainable based on the distributable net investment income they're producing.

So the reality is this yield here that's seeking Alpha, which is a platform I do absolutely love, but that yield is not accurate. It's basically true for any software you're looking at.

So that's something that is imperative you keep in mind when looking at Main Street Capital. The actual yield will be lower right now than the headline yield is showing.

Now that we've made that point, there's something else we need to point out about Main Street Capital. And there's good news and there's bad news. Now, historically, Main Street Capital has done a phenomenal job relative to other BDCs at growing their net asset value over time.

Essentially, this is them growing their intrinsic value. This is going to lead to share price appreciation and ultimately most of the time will help lead to sustainable distributions and even distribution growth.

And so since this is a BDC that has historically sustainably grown net asset value, investors are willing to pay a premium. And that's essentially been the case for almost the company's entire history with the exception of the 2020 crash.

But look at the valuation this BDC has seen over the last 5 years. On average, they sat at a price to tangible book value per share of 1.65. Right now, they're sitting very close to their average of 1.67.

So all this means is when we look at the net asset value 2025 at the end it was about 33.33. Right now the stock is trading at about 5586. They're trading at a premium valuation.

That's what it's telling us about a 1.67 times premium valuation.

Now this valuation could be justified if they can continue to grow net asset value per share over time. Most people understand this but here's what they don't understand. Just how much of a structural advantage this actually is for Main Street Capital.

Why is this a structural advantage? Well, exactly like REITs, BDC's are required by law to pay out 90% of their earnings, their taxable earnings in the form of a dividend. So, what does that mean?

Well, it means in order to continue to grow in order to fulfill all their investment needs, they can either take on debt or issue new shares. And for a BDC like Main Street Capital, currently operating in a very high interest rate environment, a lot of the times they elect to issue shares.

So, look at Main Street Capital on our stock screener. Come down here and look at shares outstanding. Like I said, they've issued quite a bit of shares over the last few years.

In fact, one of the things you'll notice is in recent headlines, they announced they're planning to sell up to 20 million more shares through an equity offering. This was announced just around a month ago.

Typically, investors look at this and think it's not good news. They see this as share dilution, and that is true to some degree unless the company can generate a positive ROI on the capital that they generate from issuing shares.

Now, historically, that is what Main Street Capital has been able to do.

But here's where things get interesting. Remember how they trade at a premium? All of a sudden, this creates an incredibly powerful flywheel. Think about it. This is one of Main Street Capital's biggest competitive advantages.

Their competitive advantage is being able to issue shares above net asset value. If Main Street Capital has a net asset value of roughly $33, but the stock is trading at $55.74, the company receives $50 of new capital when they issue a share while giving the new shareholder a claim on roughly $33 of existing net assets.

So the transaction overall is incredibly accreditive to existing shareholders. So again, there's a powerful flywheel taking place here. Their quality portfolio and historic growth of net asset value leads to a premium valuation.

And this premium valuation allows Main Street to issue stocks at a great valuation, raising additional capital to fund additional investments, which will also end up supporting earnings and dividends. So now you can see why this is so powerful.

However, there is one potential issue we do need to point out. In their recent earnings report, management made this statement. Our net asset value per share increased in the quarter primarily due to the accreditive impact of our equity issuances and the impact of a net fair value increase in our lower middle market investment portfolio.

So basically they primarily benefited from the flywheel I just explained. However, it's a little bit concerning the primary reason they grew net asset value was due to this reason.

On top of this credit quality also weakened. their non-accrral investments rose to roughly 4% of the portfolio at cost which is the highest main street capital has seen in some time.

If the overall credit quality of their portfolio keeps weakening I don't know how long investors would be willing to pay a premium.

Now to be fair overall credit quality is still significantly better than that of their peers. And one of the things we do also have to point out is one of the issues a lot of investors have had with these BDCs is they have given significant amount of loans to software and tech companies.

These are companies that are struggling right now during the age of AI. So, the thing we do need to point out though is Main Street Capital's portfolio is only about 15% software/tech exposure, which is one of the lowest exposure rates in the BDC sector.

So, again, this is another advantage for Main Street Capital.

The other advantage for Main Street Capital that we probably do need to point out to have a fair assessment is that it looks like rates are going to stay higher for longer. We might even get another rate hike by the end of the year.

And a lot of the times this is actually beneficial for BDC's because the net investment income they receive actually increases due to the loans they've given out a lot of the time being variable rate loans.

So as long as they don't see a substantial increase in defaults as a result of this higher interest rate, they should bring in more net investment income.

So now let's take a moment to talk about valuation. Yes, the best way to value is probably by determining what type of valuation multiple we're willing to pay, but this has certainly fluctuated a lot for Main Street Capital over the last 5 years.

They've been as low as a valuation multiple of about 1.28 times price attainable value per share and the recent runup in share price is really due to expansion in the valuation multiple perhaps due to the fact that we're seeing rates go and stay higher.

But we can also value Main Street Capital through the lens of a dividend discount model. If we jump over to our stock valuation sheet, let's come up here and plug in Main Street Capital.

If we jump over to our dividend discount model, let's go ahead and zoom in. So, here's what we can see in regards to Main Street Capital. If we assume 0% dividend growth, the stock is worth about $50 a share.

That implies around 10% downside. Now, I do think obviously in the short term we'll see supplemental dividends decline, but as net asset value should theoretically continue to grow as it has been historically speaking, that will allow the company to continue to grow their base dividend over time.

So, if we're talking about long-term sustainable distribution growth, if they can achieve 1%, that already implies just a little bit of upside from current prices. So, really, the market is pricing in about 1% distribution growth.

If they can get 2% all of a sudden fair value jumps up to $66.38 per share implying 19 to 20% upside.

So again the stock is not trading at an unreasonable valuation even though it is trading at a premium relative to its peers. But that's always been the case for Main Street Capital and the dividend discount model reveals why that's the case.

However, what you can't miss, what a lot of people miss is this yield you're seeing here will not be the true yield you get. I think it will very likely be lower over the next year or two as supplemental dividends do get reduced.

It's also worth pointing out that short interest for this stock is incredibly high at now over 10%. A lot of the market is still very concerned about the loans that have been given out to these software and tech companies and it's a big reason why so many of these BDCs have been absolutely hammered over the last year.

So fundamentally, Main Street Capital is still significantly stronger than their peers. That's clear when you look at the dividend dollar BDC database.
