Thank you, operator. Hello, everybody, and thanks for joining us today. I'm joined by Chief Financial Officer Ross Teune, Senior Managing Director Greg Robbins, and Managing Director Jon Simmons. Yesterday in the afternoon, we issued our earnings press release for the quarter ended March 31st. We posted an earnings presentation on our website. We're going to be referring to this presentation throughout the call today.
For those of you who are new to GBDC, our investment strategy today is, and since inception it has been, to focus on providing first lien senior secured loans to healthy, resilient middle market companies that are backed by strong partnership-oriented private equity sponsors. The headline for the quarter ended March 31st is that GBDC's results were strong. GBDC had both strong net investment income and continued strong credit performance. We'll discuss these topics in greater detail as we go through today's presentation.
Gregory's going to start. He's going to provide a brief overview of GBDC's performance for the March 31st quarter, and then he's going to hand it off to Jon and Ross for a more detailed review of the quarter's results. I'll then come back at the end to provide some closing commentary, and I'll open the line for questions. With that, Gregory, let's take a closer look at GBDC's results for the quarter and the key drivers of those results.
Thank you, David. Turning to slide four, for the quarter ended March 31st, GBDC's adjusted NII per share was $0.29, adjusted EPS was $0.55, and ending NAV per share was $14.86. The key drivers of those strong results are summarized on slide six. First, our portfolio companies generally continue to perform well. This won't come as a surprise if you happen to see the Golub Capital Middle Market Report for March 31, which we published about a month ago based on actual financial data from Golub Capital's middle market borrowers. The report for calendar Q1 showed the highest rate of year-over-year profit growth since we began tracking data in 2013. Strong earnings growth across GBDC's portfolio was reflected in the four positive credit quality trends listed on the right-hand side of the slide. We'll go into them in more detail shortly.
Second, GBDC took advantage of attractive market conditions to continue to optimize its balance sheet. We executed a second unsecured bond issuance, building on the success of our inaugural offering last year. We also closed a new corporate revolver. These financings are consistent with the strategy you've heard us discuss before. Low cost, flexible financing with limited near-term maturities. Middle market new deal activity was solid. It wasn't a record origination quarter like the December quarter, but it was meaningfully improved from last year's June and September quarters. Let's drill down on the four positive credit quality trends listed on the right-hand side of the slide, starting with our internal performance ratings. Slide seven summarizes the positive trends in the internal performance ratings of GBDC's portfolio in the post-COVID period.
Specifically, since March 31, 2020, we've seen essentially no increase in the percentage of the portfolio performing materially below expectations in categories 1 and 2. Those two categories constituted only 1.1% of the portfolio at quarter end. We have seen upward credit migration, a steady increase in categories 4 and 5, and a corresponding decrease in category 3. To remind folks, categories 4 and 5 are loans performing at or better than our expectations at underwriting, and category 3 are loans that are performing or expected to perform below expectations. In the quarter ended March 31, categories 4 and 5 increased from 81% of the portfolio as of 12/31 to 86.9% of the portfolio as of 3/31.
Category 3 decreased from 17.9% to 12% over the same period. The proportion of the portfolio rated 3 as of 3/31 was pretty close to our pre-COVID normal of around 10%. A second key indicator of continued credit improvement is the fact that non-accruals remain very low. In fact, non-accruals declined quarter-over-quarter from 1.2% to 1% as a percentage of investments at fair value at 3/31 and are now back to pre-COVID levels. We'll come back to this point in our usual discussion of GBDC's financial results. Slide eight shows two other indicators of improving credit quality, no net realized losses and solid net unrealized gains. This slide provides a bridge from GBDC's $14.60 NAV per share as of 12/31 to its increased $14.86 NAV per share as of 3/31. Let's walk through the bridge.
First, adjusted NII per share was $0.29, in line with our quarterly dividend. Second, no realized losses were recorded during the quarter. Third, net unrealized gains were $0.26 per share. These unrealized gains reflect the continued reversal of unrealized losses incurred in the March 2020 quarter. In fact, our strong unrealized gains through the post-COVID period have driven reversals of over 85% of the March 2020 unrealized losses on a price basis. Let's now take a closer look at our results for the quarter ended March 31st. For that, let me hand the call over to Jon Simmons to walk you through the results in more detail. Jon?
Thanks, Gregory. Please turn to slide 10 for a summary of our results for the quarter. You can see on the right-hand side of the slide that for the quarter ended March 31st, 2021, each of adjusted NII per share, adjusted net realized and unrealized gain per share, and adjusted EPS were consistent with the prior quarter's strong results. As a result, our NAV per share at March 31st, 2021 increased to $14.86. On May 7th, 2021, our board declared a quarterly distribution of $0.29 per share payable on June 29th, 2021 to stockholders of record as of June 11th, 2021. This distribution is consistent with our goal of having quarterly cash distributions of approximately 8% of NAV on an annualized basis. Turning to slide 11, new investment commitments for the quarter ended March 31st totaled $234.7 million.
After factoring in total exits and sales of investments of $347.5 million, as well as unrealized appreciation and other portfolio activity, total investments at fair value decreased by 2.5% or $112 million during the quarter. As Gregory noted, originations this quarter were quite strong, but so were repayments. As of March 31st, 2021, we had $44.7 million of undrawn revolver commitments and $160.6 million of undrawn delayed draw term loan commitments. These unfunded commitments are relatively small in the context of our balance sheet and liquidity position. As shown at the bottom of the table, the weighted average spread over LIBOR on new floating rate investments of 5.5% declined closer to pre-COVID levels. Slide 12 shows that our portfolio mix by investment type has remained consistent quarter-over-quarter, with One-Stop loans continuing to represent our largest investment category at 81% of the portfolio.
Slide 13 shows that GBDC's portfolio remained highly diversified by obligor with an average investment size of less than 40 basis points. As of March 31, 97% of our portfolio remained in first lien senior secured floating rate loans and defensively positioned in what we believe to be resilient industries insulated from COVID-19. Turning to slide 14, this graph summarizes the portfolio yields and net investment spreads for the quarter. Focusing first on the light blue line, this line is the income yield or the amount earned on our investments, including interest and fee income, but excluding the amortization of upfront origination fees and purchase price premium. The income yield increased by 10 basis points to 7.5% for the quarter ended March 31, 2021.
The investment income yield or the darker blue line, which includes the amortization of fees and discounts, also increased by 10 basis points to 8% during the quarter. The income yield and the investment income yield both increased primarily due to higher fee income and discount amortization. Our weighted average cost of debt, the aqua blue line, increased by 10 basis points to 3%, primarily as a result of the acceleration of deferred financing fees from early redemptions of $165 million in relatively higher priced SBIC debentures. Our net investment spread, which is the green line, which is the difference between the investment income yield and the weighted average cost of debt, remains stable at 5%. With that, I'll hand the call over to Ross to continue the discussion of our quarterly results. Ross?
Thanks, Jon. Flipping to the next two slides. Non-accrual investments as a percentage of total debt investments at cost and fair value remained low and decreased to 1.4% and 1%, respectively, as of March 31st.
During the quarter, the number of non-accrual investments decreased to six portfolio company investments from seven portfolio company investments, as one portfolio company investment returned to accrual status. As Gregory discussed in his opening commentary, as a result of strong portfolio company performance, the percentage of investments rated 3 on our internal performance rating scale decreased to 12% of the portfolio at fair value as of March 31st. As a reminder, independent valuation firms value at least 25% of our investments each quarter. Slide 17 and 18 provide further details on our balance sheet income statement as of and for the three months ended March 31st. Turn to slide 19. The graph on the top summarizes our quarterly returns on equity over the past five years, and the graph on the bottom summarizes our quarterly distributions as well as our special distributions over that same time frame.
Turn to slide 20. This graph illustrates our long history of strong shareholder returns since our IPO. Slide 21 summarizes our liquidity and investment capacity as of March 31st, which remains strong with over $800 million of capital available through cash, restricted cash, and availability in our revolving credit facilities. We also highlight our continued progress during the quarter on optimizing the right-hand side of our balance sheet. Three key highlights. First, on February 11th, we closed on a $475 million revolving credit facility with JPMorgan, which matures on February 11, 2026, and has an interest rate that ranges from one-month LIBOR + 1.75% to one-month LIBOR + 1.875%. Second, on February 24th, we issued $400 million of unsecured notes, which bear a fixed interest rate of 2.5% and mature on August 24th, 2026.
With the completion of our second unsecured debt issuance, our percentage of unsecured debt as a percentage of total debt increased to 38% as of March 31st. Finally, on February 23rd, we decreased the borrowing capacity under our revolving credit facility with Morgan Stanley to $75 million. After the end of the quarter, we further amended this revolving credit facility to, among other things, extend the reinvestment period through April 12th, 2024, extend the maturity date to April 12th, 2026, and reduce the interest rate on borrowings to one-month LIBOR + 2.05% from one-month LIBOR + 2.45%.
Slide 22 summarizes the terms of our debt capital as of March 31st. Last, on slide 23, we summarize our recent distributions to stockholders. Most recently, our board declared a quarterly distribution of $0.29 per share payable on June 29th to stockholders of record as of June 11th. With that, I'll now turn it back to David for some closing remarks. David?
Thanks, Ross. To sum up, GBDC had a strong quarter. Adjusted net investment income matched our dividend, realized credit losses were nil, and unrealized gains were substantial, continuing the reversal of unrealized losses that we incurred in the March 31, 2020 quarter. Let's talk about our outlook for the rest of this calendar year, and then we'll take your questions. At the risk of sounding out of character, the headline is that I'm cautiously optimistic. We believe GBDC has four powerful tailwinds going into the coming period. One tailwind is GBDC's strong portfolio performance. We've highlighted through today's presentation the positive credit trends that we've seen over the last quarter and the last 12 months. Our pre-COVID underwriting has proved strong, and as a consequence, we won't be distracted in the coming period by needing to play defense on a troubled portfolio. A second tailwind is the economy.
Many of the sectors we like to lend to are booming. Areas like software and healthcare and business services. Just look at the record profit growth that we reported in the Q1 Golub Capital Middle Market Report that Gregory referenced. Going forward, the economy's reopening, fiscal stimulus is taking effect, monetary policy remains accommodative. These factors all point to likely continued economic strength for the next several quarters. A third tailwind comes from the strength of the private equity ecosystem in which we operate. The private equity industry has over $1.7 trillion of dry powder. That's according to Preqin data. In the first quarter of 2021, the private equity industry had its strongest ever fundraising quarter. That's according to Private Equity International. We believe there's a lot of pent-up demand for sponsor-driven middle market M&A now that COVID uncertainties are fading.
We anticipate that the coming period's likely to be one of robust private equity deal-making. Finally, a fourth tailwind is that GBDC has ample liquidity and flexibility to capture this attractive opportunity set. You'll recall that one of our key goals in navigating COVID was not only to fortify the company's balance sheet in the face of COVID-related uncertainty, but also to put the company on even stronger footing to take advantage of new opportunities. I think we're in a good position to do that. That all said, you know I'm not by nature an optimist, let me elaborate on three reasons why I'm only cautiously optimistic. First, from a macro perspective, while near-term economic prospects look bright, there is longer-term uncertainty, especially around inflation.
Our economy's booming, and yet at the same time, government and central bank policy right now is to apply even more fiscal stimulus and even more accommodative monetary policy. I don't know how that's going to play out. I don't think anybody can predict the outcome of this economic policy cocktail. A big question is whether price increases that we're seeing right now in commodities and wage pressure, whether that's going to translate into accelerating inflation. I don't think anybody knows the answer to that yet. Second reason for caution, liquid credit markets are strong. High yield spreads are at 20-year tights. If this rate continues, I'd expect to see some continued pressure on loan spreads, terms, and leverage in our market. As I've said many times before, the middle market is insulated, but not immune from what's going on in broader credit markets.
Third reason for caution, COVID's still raging in many parts of the world. This isn't just a tragedy for all the people in those communities. It also means we're very likely to see new COVID variants develop, variants our vaccines may not protect us from. We may not be done yet with this dreadful COVID virus. Enough on the cautions. There are always clouds in the sky. Overall, I think GBDC is very well-positioned, and that the coming period will likely play to Golub Capital's strengths. Thanks, operator. Please open the line for questions.
At this time, if you'd like to ask a question, please press star one on your telephone keypad. Press star one for any questions or comments. We'll pause for just a moment to compile the Q&A roster. Your first question comes from Finian O'Shea with Wells Fargo Securities.
Hi, everyone. Good afternoon. First question, David, on the outlook for origination. Historically, the Golub platform has been very active in these very large unitranche offerings, some exceeding $2 billion. Those seem to be coming back, but in our observation, contrary to former periods where we'd see them, today the syndication market appears very high as well. Do you agree with that? First, I guess, are these large market opportunities coming back? Second, do they represent lenders competing more heavily with the syndicated market or the sponsor demand tilting in your favor? I'll stop there.
Thanks, Finn. Good to hear from you. Let me take a step back in answering that question, because I think there are a number of trends that are running in different directions. First trend is the development of a large unitranche product that sponsors can use if they want it. I think there's definitely been a marked change over the last couple of years. We've been the leader, as you point out, in providing these large unitranches. It's not just us. I think sponsors increasingly look at the possibility of financing their deals with a large unitranche as one of the options on the menu in a way that, even as recently as three or four years ago, wasn't the case. Now, under what circumstances do sponsors prefer doing a large unitranche to doing a broadly syndicated first lien, second lien deal? That's a second question.
You're 100% right that when the broadly syndicated markets are hot, that it's possible sometimes to get a combination of pricing or leverage or terms or all three that are more attractive in the syndicated market than are possible to get in a private One-Stop. Even when markets are receptive like they are now, there are often transactions where a private One-Stop makes more sense. That may be because the sponsor needs to move more quickly than the syndicated market will permit or needs to arrange a deal with more confidentiality, doesn't want to share information with a lot of market participants. It's a situation in which the company is going to be doing serial acquisitions and we're scaling up the company. It's going to be easier using a One-Stop capital structure as opposed to a more complicated multilayer capital structure.
My view is there's a secular trend toward increased market share for larger One-Stops. That's going to continue. There will be ups and downs in that secular trend that will be driven by what we're seeing in the M&A market and what we're seeing in the broadly syndicated market. I think right now, to your point, we're seeing a particularly robust syndicated market, and it's harder for private lenders to compete with than during periods when those markets are choppy. One thing I think we can all be certain of, which is that choppy markets will return at some point, and one has to look at these trends over an extended period of time. Make sense?
Yeah. No, absolutely. It's very helpful. I'll just do a follow on your economic commentary at the end on the item of inflation, potentially labor inflation. We are seeing on the higher level more viewpoints that suggest that that's a potential concern. Do you see anything in your Portfolio companies that are more labor-intensive, perhaps restaurants, so forth, any indications of emerging pressure on that front?
I'm seeing trends in our portfolio that are reflective of what we're all reading about in the front pages of the financial press, which is that it's increasingly challenging in many areas of the country to hire. I think that can be a good thing or a bad thing, depending on how one looks at it. I think the good aspect of it is that it's leading to some higher wages in some areas which, over the course of the last two decades, have seen stagnant wages. That's probably a good thing. It's a bad thing if this becomes part of accelerating inflationary expectations, which then drives inflationary expectations into other areas. I think it's going to be very interesting to watch the Bureau of Labor Statistics data over the course of the coming months. Tomorrow actually is the next release.
One of the pieces of data I like to look at, I think is really interesting, is they release a month-over-month version of inflation in addition to their annual version. If you look at the recent month-over-month data, it's been accelerating. I'm very interested to see whether we're going to see a continuation of that acceleration or whether we're going to see a stabilization.
Interesting. We'll check that out tomorrow. Well, thanks for taking our questions and congrats on the quarter.
Thanks, Finn.
Your next question comes from Ryan Lynch with KBW.
Hey, good afternoon, guys. I had a couple questions on kind of your thoughts during your underwriting process for a couple different themes. You guys are obviously a big lender in the software space. It seems that annual recurring revenue lending is becoming much more and more prevalent. It seems like that's even accelerated kind of more during COVID and even now, kind of as we're recovering coming out of COVID. Just can you talk about, from a higher level, how do you think about lending based on ARR versus cash flow for some of these software names or other recurring revenue names?
Sure. Let me provide some context first, just for those who perhaps aren't so familiar with what we're talking about. Golub Capital's been a leader in providing financing to the sponsor-backed buyouts of software companies for many, many years, more than a decade. About eight years ago, in addition to lending to more mature software companies that are generating significant cash flows, we began lending to companies that were at an earlier stage. We refer to these as recurring revenue loans. These are companies that have a proven software as a service model. They've got a great product. They've got loyal customers. They've got significant recurring revenues that are growing rapidly. Their clients are renewing their business with them at high rates. In part because these companies are growing rapidly and are investing a lot in sales and marketing, they're either not highly profitable.
In some cases, they're not profitable at all. Traditional credit metrics don't look the same with these companies as those same credit metrics look like with the more mature software companies. We were a pioneer in identifying this recurring revenue loan niche as being an attractive niche. We've been very active in it, Ryan, as you point out. Over the last eight years, we've had virtually no losses in this space. It's been a very successful space for Golub Capital. As we look at those loans, the key underwriting criteria boil down to whether we believe there'd be a strategic buyer who'd want to buy the company at a price that would be more than sufficient to get us out if the growth projections of the company were not fulfilled.
If something happened that caused the company's business plan to increase revenues at a rapid rate not to be sustainable, we want to make sure there's an appropriate second way out for us so that we are not going to be subjected to a meaningful credit loss. This is tricky because you're talking about companies that are not highly profitable, that are earlier stage in their development, and I think it requires enormous amounts of expertise, underwriting expertise, industry expertise, and underwriting skill.
I think it's something we're very good at. I don't think that it's inappropriate. I think it is appropriate that there's been some commentators around saying that there's some people who are active in this space who maybe don't have the level of expertise to be as active as they currently seem to be. This is not the easiest-to-learn kind of lending that there is. This is tricky stuff.
That's really helpful color on your overall thought process and your history in that area. Kind of on that same sort of topic, though, obviously, there were certain businesses that were significantly impacted on a negative side from COVID. Those businesses, if they've survived, are probably going to have some pretty major tailwinds as the economy reopens. Conversely, in some of these software names, potentially a lot of the growth or adoption, as the economy or a lot of these businesses have to digitalize and kind of work from home. Some of that growth or adoption might have been accelerated or pulled forward during COVID, and there might not be the same sort of tailwinds going forward.
How are you guys thinking about that and taking that into your underwriting process as you guys look at more deals in the software space, kind of at this point in time with, hopefully, the economy reopening and some of those acceleration of some of those trends may be fading?
Yeah. I guess I'm not a big believer in your premise. I think in many parts of the software industry-- Look, every software company's got to be looked at individually. What we've seen in many parts of our software universe is that there were COVID impacts. Not to say there wasn't still revenue growth, but the pace of revenue growth would have been higher if the sales force had been able to travel and meet in person with customers and push along the sales pipeline in the traditional way.
If your premise was right, I think we'd be seeing right now a notable decline in the growth rate of software companies generally. If I harken back to the Golub Capital Middle Market Index report that Gregory alluded to in our opening remarks, that's not what the numbers show. The numbers show continued very high revenue growth for software companies, and my bet is that that's going to continue.
Okay. That's fair enough. Just one last one if I can. Kind of switching gears to your capital structure first. Congrats on your second unsecured debt issuance. That was a very attractive rate. Kind of on that point, when you guys were initially talking about layering on some unsecured debt, I kind of got the impression, obviously, correct me if I'm wrong, that you guys were going to maybe have a thirty or so percent of your liability structure in unsecured notes.
With this most recent rate of 2.5%, of course, that rate can always move depending on the market terms. Of course, you want to ladder out your maturities for that unsecured debt. Does that change, though, that 2.5% rate when you guys issued your last bond? Does that change kind of the way you guys are thinking about layering on unsecured debt as a percentage of your liability structure?
That's a great question. Ryan , I think we always think about the debt structure in the same way, which is it's a balancing of multiple goals. Your point, if I'm understanding you right, is 2.5%, that's really low, it's particularly low by historical standards for unsecured debt. Would that drive us toward potentially increasing the proportion of unsecured in our stack? I mean, the answer is yes, subject to other goals too, including, as you point out, laddering maturities.
Also subject to our needing incremental capital. Right now, if you look at our right-hand side of the balance sheet, we've got an enormous amount of unused capacity with almost none of the JPMorgan line drawn. We certainly want to be careful not to take on incremental unsecured that we don't need. In the long run, if unsecured is as inexpensive as it is now, I think that does change the calculus for the proportion of the capital structure that it may make sense to have an unsecured.
Okay. Understood. That's all for me. I appreciate the time this afternoon, guys.
Your next question comes from Robert Dodd with Raymond James.
Hi, guys, and congratulations on the quarter, and the portfolio looks in really good shape. On one of the comments you made, David, I mean, the liquid markets are hot. There is a concern that I think you have, I have. Not so much about the spreads. They're going to do what they do. The terms. The terms and structures. If you were to look at things that say, coming into your pipeline today versus maybe were coming in in January, has the expectation from the borrower or the hope maybe from the borrower shifted even over that timeframe on the structure side, less so the pricing? I mean, are people just asking for more and more, and can we expect the structural protections to maybe weaken a little bit as we go forward from here?
I think of these trends more broadly, Robert, as are we in a borrower-friendly period or a lender-friendly period? When you're in one or the other, things tend to keep moving in that direction until there's a turnabout. Since, I would say June of 2020, we've been on a borrower-friendly trend. I think over successive months and quarters since June of 2020, I would say yes to your question. I would say that there's been movement that's been in favor of borrowers.
That's been true in all three of pricing, meaning spreads, terms, meaning documentation terms and covenants, and levels of leverage. All three. In liquid markets, those changes have been more pronounced, more significant than they've been in private markets. I think we're seeing it in private markets as well. It all goes back to that same phrase I repeat like a mantra. We're insulated but not immune in the middle market from what's happening in broader credit markets.
Yeah. Understood. Another one, if I can cut you. Obviously, when you look at the BSL market doesn't have delayed draw term loans, for example. It's one of the advantages of doing some of these mega transactions. When the incumbent borrowers that you've got in your portfolios, is there any increase in reaching out, beginning the process of maybe adding or increasing DDTL opportunities if the M&A market looks pretty hot?
Are the existing borrowers looking to maybe expand more into DDTL? That was something, obviously, a year ago we were trying to reduce. If that's the case, does that add extra incumbency protection? Because obviously that's something potentially you can do, but the BSL market probably isn't going to offer people.
DDTLs are definitely a tool that some sponsors like to use, especially if they're doing buy and build strategies. You're correct that it's easier to do it in private deals. It is possible to do it in a syndicated deal. There are syndicated deals that have DDTLs. It is easier to do in private deals. It's less expensive to do from an issuer standpoint in private deals. A very significant chunk of the business that we do with existing companies in our portfolio comes in the form of acquisition financing and that, o ften is DDTLs. Not always.
Sometimes it's some incremental term loan and some DDTL at the same time. Sometimes it's only incremental term loan. I think a point you were making is really important, which is in any of these scenarios, being the incumbent lender, being the incumbent lead is hugely valuable because you're in the pole position. You're the go-to lender for incremental needs. Absent there being some really compelling reason to do a global refinancing, which is distracting and expensive.
I appreciate that. Thank you.
I would now like to turn the call back over to David Golub for closing remarks.
Thank you, Brenda. I appreciate everyone joining us today. Thanks for your questions. Thanks for listening. As always, if you have any questions over the course of the coming quarter, please feel free to reach out. We look forward to talking to you again next quarter.
This does conclude today's conference call. Thank you for your participation. You may now disconnect.
