Joshua Easterly
ExecutivesGood morning, everyone, and thank you for joining us. With me today, our President, Bo Stanley; and our CFO, Ian Simmonds. Before we get started, I want to take a moment to express our profound sorrow following the tragic events that unfolded in our city earlier this week. On behalf of our entire company, our hearts go out to the victims and their loved ones. Our thoughts and prayers are with the families, first responders, the local firms affected by this [indiscernible] and random act. After market closed yesterday, we reported the second quarter adjusted net investment income of $0.56 per share on an annualized return on equity of 13.1%, and adjusted net income of $0.64 per share or an annualized return on equity of 15.1%. As presented in our financial statements, our Q2 net investment income and net income per share inclusive of the accrued capital gains incentive expenses were $0.54 and $0.63, respectively. As a reminder, any differences between the adjusted and reported metrics is a noncash expense related to accrued fees on unrealized gains from the valuation of our investments. The difference between adjusted net investment income and adjusted net income of $0.08 per share in Q2 was largely related to net unrealized gains from the impact of tightening credit spreads on the valuation of our investments and positive portfolio of company-specific events. I'd like to frame an important shift we are -- we see unfolding in the sector following the mini credit cycle that took place over the last few years beginning in mid-2022 with the rapid rise of interest rates. Through that cycle, public BDCs, including SLX experienced idiosyncratic credit issues, putting downward pressure on net asset values. While the average public BDC [indiscernible] net asset value per share declined by 10.1% from the fourth quarter 2021 through the first quarter of this year, SLX's net asset value per share increased by 1.2% over the same time frame or 2% through Q2. Even with the rise of nonaccruals and the losses we recognize, our disciplined approach to capital allocation allowed us to [indiscernible] our cost of equity and grow net asset value. Over this period, we generated a total economic return calculated as change in net asset value plus dividends 42.6%. We're doubling the average of our public BDC peers of 19.1%. We expect that credit issues are predominantly behind us. This is evidenced by an improvement in nonaccruals for SLX this quarter and also for the sector more broadly, which experienced a marginal decrease in nonaccrual for Q1. While we don't have pure data for Q2, we expect the trend to continue this quarter. This should result in a convergence between net investment income and net income for the sector. Under the premise that credit has broadly stabilized, we anticipate the focus for the sector shift from credit quality to dividend coverage as portfolio yields declined from the combination of lower forward rates and tighter portfolio spreads. For SLX, adjusted net investment income in Q2 of $0.56 per share exceeded our base dividend by 22%. This robust dividend coverage is tied to our ability to source and execute on differentiated investment opportunities. This is clearly demonstrated by our weighted average spread on our new first lien investments in the second quarter of 6.5%, which compares to the public BDC sector average of 5.3% on new issue first lien loans for the first quarter. Again, we don't have comparable Q2 data for the period, but we expect the weighted average portfolio spread to decline further this quarter. We continue to caution that there has been complacency in the sector. In addition to the pursuit of AUM growth, we believe this is largely driven by a backward-looking focus on LTM metrics that reflect an elevated rate and spread environment that's no longer indicative of today's investment landscape. What matters say and always is a forward view, and we believe our approach will continue to positively distinguish our earnings profile. Looking ahead, we estimate the quarterly earnings power of our business to exceed our base dividend level assuming stable credit leverage in the middle of our target range and conservative fee incurred. As of June 30, our net asset value was $17.17 per share, representing an increase of 70 basis points from at $17.04 as of March 31. Yesterday, our Board approved our base quarterly dividend $0.46 per share to shareholders of record as of September 15, payable on September 30. Our Board also declared a supplemental dividend of $0.05 per share related to our Q2 earnings to shareholders of record as of August 29, payable September 19. Net asset value per share adjusted for the impact of the supplemental dividend that was declared yesterday was $17.12. We estimate that a spill over income per share of approximately $1.30. With that, I'll now pass it over to Bo to discuss this quarter's investment activity.
Robert Stanley
ExecutivesThanks, Josh. I'd like to start by sharing some thoughts on the M&A environment and how that's impacting activity in our portfolio. As we've discussed for several quarters, the M&A market has yet to deliver the meaningful rebound that many had anticipated in 2025. This muted transactional environment is clearly reflected in the leveraged loan market where M&A-related loan volume was down approximately 31% in the second quarter compared to the first, and second quarter loan volume marked its lowest levels since the fourth quarter of 2023. From our perspective, a meaningful reacceleration and M&A requires a catalyst for 1 of 3 areas: economic growth, interest rates or time. Given the prevailing uncertainty around trade policy, a surge in near-term growth appears unlikely. And the forward curve suggests rates will remain higher for longer. This leaves time as the most important factor. In an environment of slower growth in elevated rates, sponsors and management teams need a longer runway for portfolio company earnings to grow and generate an appropriate return on investments. While we can't predict the future, we estimate the timing of M&A activity taking inspiration from the Hubbert peak theory, which was used in the 1950s to estimate when U.S. oil production would peak. Utilizing data sourced from [indiscernible], the medium buyout multiple at peak levels in 2021 has declined roughly 3 turns compared to the medium for closed buyout deals year-to-date. If we assume no multiple compression from the peak in 2021 and an average annual EBITDA growth rate of approximately 9%, consistent with historical S&P earnings growth, it would take approximately 4 to 5 years for a buyer to earn an appropriate multiple of money on their investment. If we apply the same assumptions, but including the rerating of multiples since the rate hiking cycle, this lengthens the timeline to 6 to 7 years, implying an additional 2 years needed to grow earnings until an appropriate multiple of money is achieved. Based on our analysis, the earlier wave of investments from the pre-COVID vintages are now approaching the 6- to 7-year mark, which should moderately increase M&A activity in the next few quarters. As for the record-setting post-COVID pre rate hiking vintages of 2021 and early 2022, which we estimate make up more than 40% of the current private equity net asset value, sellers need 6 to 8 additional quarters to reach an acceptable multiple of money, implying a further delay of the broad-based return of M&A activity that many are predicting. We recognize there are additional factors at play, and this time line will vary for different segments of the market. For example, investment-grade M&A is likely the first to return given the favorable regulatory environment. These businesses are also less levered compared to noninvestment-grade companies, which means they have less sensitivity to interest rates. While the widespread return of M&A in our markets remains a future prospect, we have observed a noticeable shift in market sentiment beginning in late June and strengthening through July. In addition to some green shoots related to the buy-and-bill strategies, we have more notably seen a pickup in non-M&A-related activity within sponsored portfolios, such as duration management transactions. We expect these types of financings to be a prominent theme in the second half of the year as sponsors work to optimize their portfolio of companies in preparation for an improved exit environment. We believe we are very well positioned to provide the kind of complex bespoke capital solutions these situations require creating attractive risk-adjusted returns for our shareholders. Turning now to activity in the second quarter. We provided total commitments of $289 million and total fundings of $209 million across 13 new investments and 4 upsizes to existing portfolio companies. To characterize our origination activity in Q2, approximately 30% of our commitments were sourced outside the sponsor channel. The remaining 70% came through the traditional sponsor-backed finance market, where we will leverage our deep relationships and platform scale to deploy capital into investments that are on an appropriate risk-adjusted return for our business. An example of our nontraditional transactions in Q2 and is our direct to company investment in [ Genesis Health. ] This was an accounts receivable securitization financing, where the combination of our deep knowledge and specific health care themes combined with the long-standing track record in asset-based loans created a unique investment opportunity for SLX shareholders. With the resources in place across the [indiscernible] platform, including dedicated ABL and health care teams, we have the ability to source and underwrite these off-the-run transactions that diversify our assets as well as our return profile relative to the sector. Another differentiated investment in our portfolio is Caris Life Sciences. As a reminder, we made initial debt and equity-linked investment in Caris in 2018, and subsequent equity-linked investments in 2020 and 2021. We fully exited our debt security in 2023, and the company recently completed an IPO in June. We still hold an equity position today, which is [indiscernible] quarterly based on the company's closing stock price on the last day of the quarter, while equity positions are a small part of our overall portfolio, our ability to embed potential incremental economics into our business through unique thematic sourcing and disciplined underwriting service as a competitive advantage for our shareholders. I'd like to spend a moment providing an update on one of our existing portfolio companies, Lithium Technoloies that had previously been on nonaccrual status. During Q2, we navigated their sale process and restructuring of the business, working closely with the new sponsor to negotiate and drive an outcome. As a result of the restructuring, we hold a smaller loan that is paying cash interest and an earn-out equity security. This transaction had no material impact on our net asset value in Q2 as the realization of our original investment was consistent with our valuation as of March 31. Lithium has therefore been removed from nonaccrual status following the restructuring. Moving on to repayment activity. The second quarter marked the third consecutive quarter of elevated payoffs. Total repayments in Q2 were $389 million. This repayment activity contributed to another strong quarter of activity-based fee income, excluding other income totaling $0.11 per share in Q2 relative to our 3-year historical average of $0.05 per share. The repayment activity we experienced during the quarter was driven by a mix of refinancings and M&A activity of the excess that involve refinancing transactions, the majority were completed at lower investment spreads. Our portfolio continues to reflect our disciplined capital allocation as only 6.2% of investments by fair value as at quarter end had a contractual spread of 500 basis points or below. While we don't have the comparable Q2 peer data set available yet, this is nearly 5x less than the average of 29% of public BDC portfolio spreads up 500 basis points or below as of March 31. A large portion of our payoffs during the quarter came from older pre-2022 vintages, reducing our exposure to these assets to 29% of the portfolio by cost. This compares to 59% or roughly double pre-2022 vintage exposure for the public BDC sector average as of March 31. We view this as a positive differentiator for our business as it reflected greater exposure to newer vintage assets that were originated following the commencement of the rate hiking cycle in early 2022. Given this greater exposure to new vintage assets, [ 37% ] of our exits were post 2022 investments, resulting in incremental economics of shareholders driven by prepayment fees. Moving on to the portfolio metrics and [indiscernible]. Despite recent competitive dynamics, we remain committed to high documentation standards that provide robust downside protection. At quarter end, we maintained effective voting control of 78% of our debt investments, an average of 2 financial covenants consistent with historical levels. After managing prepayment risk, the fair value of our portfolio as a percentage of call protection is 94.1%, which means that we have protection in the form of additional economics that would flow through net investment income should our portfolio get repaid in the near term. As of June 30, the weighted average total yield on our debt and producing securities at amortized cost was 12.0% compared to 12.3% as of March 31. Given the meaningful payoff activity we experienced in Q2, the decline primarily reflects payoffs of higher-yielding assets exceeding the yields of new investments funded during the quarter. While credit spreads have remained competitive in Q2, our omnichannel sourcing capabilities enabled us to put capital to work in a disciplined manner demonstrated by a weighted average spread on new first lien investments of 652 basis points, which compares to a spread of 533 basis points on new issued first lien loans for the BDC peers in Q1, as Josh mentioned earlier. Moving on to the portfolio composition and key credit staff across our core borrowers for whom these metrics are relevant, we continue to have conservative weighted average attachment and detachment points of 0.3x and 5.0x, respectively, and our weighted average interest coverage remained consistent at 2.1x. As of Q2 2025, the weighted average revenue and EBITDA of our core portfolio of companies was $377 million and $114 million, respectively. Median revenue and EBITDA was $147 million and $46 million, respectively. Finally, overall portfolio performance is strong with weighted average rating of 1.10 on a scale of 1 to 5 with 1 being the strongest. The Lithium restructuring resulted in an improvement in nonaccruals quarter-over-quarter from 1.2% of the portfolio at fair value to 0.6%. As of June 30, we have 2 portfolio companies on nonaccrual status. With that, I'd like to turn it over to my partner, Ian, to cover our financial performance in more detail.
Ian Simmonds
ExecutivesThank you, Bo. For Q2, we generated adjusted net investment income per share of $0.56 and adjusted net income per share of $0.64. Total investments were $3.3 billion, down slightly from $3.4 billion in the prior quarter as a result of net repayment activity. Total principal debt outstanding at quarter end was $1.8 billion, and net assets were $1.6 billion or $17.17 per share prior to the impact of the supplemental dividend that was declared yesterday. Our average debt-to-equity ratio was 1.2x, up from 1.19x in the prior quarter, and our ending debt-to-equity ratio decreased from 1.18x to 1.09x quarter-over-quarter. Average leverage was higher than ending leverage, driven by the timing of repayment activity, which predominantly occurred towards the end of the quarter. We continue to focus on maintaining leverage within our target range of 0.9x to 1.25x. And since the regulatory change in late 2018, we have operated with an average quarterly debt-to-equity ratio of 1.03x. Leverage remains within our target range and above our historical average, providing ample capital for new investment opportunities. In terms of balance sheet positioning, we had approximately $1.1 billion of unfunded revolver capacity at quarter end against $159 million of unfunded portfolio company commitments eligible to be drawn or coverage of approximately 7x. Our quarter end funding mix was represented by 71% unsecured debt. As a reminder, we proactively completed several capital markets transactions during Q1, strengthening our balance sheet. Following these transactions, our capital, liquidity and funding profile remain in excellent shape. Further, we have no near-term maturities with our nearest obligation being $300 million of unsecured notes not occurring until August 2026. We did not issue any shares through our ATM program during the quarter. Pivoting to our presentation materials, Slide 8 contains this quarter's NAV bridge. Walking through the main drivers of NAV growth, we added $0.56 per share from adjusted net investment income against our base dividend of $0.46 per share. As Josh mentioned, there was approximately $0.02 per share of accrued capital gains incentive fee expenses related to this quarter's net realized and unrealized gains. There was a $0.13 per share reduction to NAV as we reversed net unrealized gains on the balance sheet related to investment realizations and recognized these gains into this quarter's income. The reversal of unrealized gains this quarter was primarily driven by early payoffs resulting in accelerated OID and [ call ] protection. There was a $0.09 per share positive impact to, NAV primarily from the effect of tightening credit market spreads on the fair value of our portfolio. Portfolio company-specific events increased NAV by $0.07 per share. And finally, there was $0.06 per share of net realized gains, mainly from equity realizations in ReliaQuest and [ Murchison. ] As Bo mentioned earlier, there was no material impact to net asset value from the Lithium restructuring as the realized value was consistent with our fair value as of March 31. As shown in our financial statements, there was an unrealized gain from the reversal of the previous unrealized loss that was equally offset by a realized loss this quarter. Moving on to our operating results detailed on Slide 9. We generated $115 million of total investment income for the quarter compared to $116.3 million in the prior quarter. Interest and dividend income was $97.2 million, down slightly from prior quarter, primarily driven by lower dividend income and a decline in foreign base rates. Other fees representing prepayment fees and accelerated amortization of upfront fees from unscheduled paydowns were lower at $10.2 million compared to $14 million in Q1, driven by the significant Arrowhead prepayment fee that occurred in Q1. Other income was $7.6 million, up from $3.5 million in the prior quarter. Net expenses, excluding the impact of the noncash accrual related to capital gains incentive fees was $61.4 million up marginally from $60.7 million in the prior quarter, primarily driven by expenses incurred for the annual and special shareholder meetings held during the second quarter. Our weighted average interest rate on average debt outstanding decreased slightly from 6.4% to 6.3%. This was primarily the result of a decline in foreign base rates. Before handing it back to Josh, I wanted to provide an update on our ROE metrics. Year-to-date, we've generated strong annualized ROEs based on adjusted net investment income and net income of 13.3% and 11.7%, respectively. We believe this reflects our broad origination platform, ability to embed economics into our portfolio and disciplined capital allocation. Based on our year-to-date performance and our expectation of the quarterly earnings power of the business in the second half of the year, we anticipate generating a return on equity based on adjusted net investment income in the top half of our previously slated range -- stated range of 11.5% to 12.5% for the full year. If activity-based fees remain elevated as we have experienced in recent quarters, there is potential to exceed the top end of that range. With that, I'll turn it back to Josh for concluding remarks.
Joshua Easterly
ExecutivesThank you, Ian. It's a tricky investment environment driven by the imbalance between supply and demand of capital. Competition is elevated and it's increasingly difficult to generate outsized returns. However, Sixth Street was built to navigate such complexity. We have a long and proven history of delivering for our shareholders through challenging backdrops including the emerging -- the energy market volatility that started in late 2014 and continued in 2015 and '16, the global pandemic in 2020 and 2021, and most recently, the interest rate hiking cycle of 2022 and 2023. Through past dislocations, we have consistently proven our ability to protect capital and generate value. During these years, SLX generated an average annualized return on equity of 13.7%, a significant outperformance compared to the 7.5% average for our public BDC peers over the same years. While today's market presents a different set of challenges, our core strategy remains unchanged. Leveraging a deep bench of talented individuals who work collaboratively to source and underwrite investments that differentiate our return profile. This investor first approach is not just a guiding principle, it is deeply embedded in our firm's culture and business model. To appreciate our strategy, one must first understand the framework of our industry. The path to outperformance in the highly regulated BDC sector is exceptionally narrow. First, there is little to no opportunity for differentiation through leverage or financing as the liabilities have the balance sheet offers no real source of excess return. Second, most industry participants operate on a similar cost structure of fees and expenses. Consequently, our performance must be generated almost exclusively on the asset side by sourcing differentiated investments and just as importantly, minimizing investment losses. This is ultimately accomplished by the team, which becomes the real differentiator. This is the core of the Sixth Street model where our platform has consistently shined. For over a decade as a public company, the human capital advantage has delivered strong risk-adjusted returns for our shareholders. Looking forward, we will lean on these proven capabilities, remaining steadfast to our promise to be an investor first firm dedicated to building a robust business that compound value over the long term. With that, thank you for your time today. Operator, please open up the lines for questions.
Operator
Operator[Operator Instructions] And our first question comes from Brian McKenna with Citizens.
Brian Mckenna
AnalystsJosh, I'm curious how you think about portfolio diversification as it relates to risk. Some of your larger peers have average position sizes of 20, 30, 40-plus basis points. I look at the average position at TSLX continues to be around 90 basis points. So how do you balance managing risk through diversification but also sizing positions appropriately in order to match your conviction in an investment?
Joshua Easterly
ExecutivesYes. It's a good question. Look, we are -- I think we've done a really good job of managing risk on an idiosyncratic basis. At the end of the day, it's all about idiosyncratic underwriting. And when you look at SLX's loss history and the inverse of that NAV growth over time compared to the rest of the industry, I think it speaks for itself as it relates to risk management -- set of risk management parameters, to be honest with you. At the end of the day, this is about -- this business is about originating and underwriting credits that have an assymetrical SKU where you cut off the left tail and minimizing losses. That is your -- as we mentioned in the script, that's the only path at the end of the day to outperformance because of the regulatory framework in the industry. You don't have the ability to do it through capital structure or financing costs. It's just about your portfolio yields compared to your losses and your risk management, and I think we have the best-in-class track record of that.
Brian Mckenna
AnalystsOkay. That's super helpful. And then one of your partners was speaking in a public forum recently. They talked about how an investable theme typically lasts about 1 to 3 years at Six Street. So what are some of the more attractive themes you're investing into right now? And really, what areas of the market are the best return opportunities per unit of risk? And then what are some of the sectors or scenes you're shying away from?
Joshua Easterly
ExecutivesYes. So look, I think the most challenged -- although we still pick our spots is the on-the-run sponsored finance business, that tends to be the most crowded at the moment. Although we still pick our spots in that space if we have industry overlap. But generally, we like more of the run nonsponsor stuff today, most definitely harder to source and harder to underwrite for sure and -- but has generally led to [indiscernible] of excess return. And so that could be [ spec pharma ] that could be asset-based lending, that could be energy, those tend to be less picked over spaces with less capital. And generally, they tend to have less kind of traditional private equity sponsorship. Bo, do you have anything to add there?
Robert Stanley
ExecutivesThe other thing I'd say is we continue to build out sector capabilities across the platform and our shareholders are beneficiaries of that as they source deals across the capital structure. And we still are active in the sponsor space, but it's going to be where our themes overlap. And we're not competing with commodity providers of capital.
Operator
OperatorOur next question comes from Mickey Schleien with Clear Street.
Unknown Analyst
AnalystsJosh, a high-level question to start about the sector. in general. The growth of nontraded BDCs and other funds investing in private credit continues to broadly pressure loan spreads, and we saw a little bit of that in your portfolio. Do you think that process is a secular trend? And do you expect spreads for debt liabilities in the space to also compress or maybe for fee structures to come down and allow listed BDCs to maintain their arbitrage? Or do you think investors need to begin to accept lower ROEs in the sector? I realized Sixth Street may not be as exposed to these trends, but I think everyone would like to hear your views.
Joshua Easterly
ExecutivesYes. By the way, Mickey, congrats on the new seat. Glad you joined the call. You are an important voice in this, so thank you. Look, I wrote extensively about this last quarter. So I would point people to my letter on this subject last quarter, about 90% of asset growth, which I think you're referring to, and flows came from the perpetually offered nontraded space. And I would include interval funds, emerging interval funds in that category as well. So I think the challenge you have is in this particular time, the -- and we talk about this in this letter -- I mean in this earnings script, if there is complacency, which is we think investors are looking at the historical return backward-looking LTM, which is higher than the [indiscernible], given both the combination of the higher spread in the back book compared to reinvestment spreads today plus the difference between the downward sloping SOFR curve. And so you have spot SOFR, which is somewhere between 80 and 90 basis points above the SOFR swap curve. And so as people do, they kind of look at things and say, what's the return profile been? But we think the return profile is going lower. And that is a -- that needs to shake out. I would expect that, that will shake out and the flows will change, flow get reallocated to those managers that have been able to continue to produce in the new environment and attractive ROE. When you historically look at balance sheet, when you sort of look at balance sheet heavy financials, we were hard to find a balance sheet heavy financial that had an ROE requirement less than 9%. And so if it's banks or [ FinCos ] or BDCs. So I'm not super hopeful that the market is going to wake up, especially in an environment where treasuries, the 30-year treasuries [ near 5 ] that they're going to require a 6% or 7% ROE. It doesn't seem like a spread that's super competitive risk-adjusted returns. So I think we're in this moment of time where the back book and the spot forward is hiding some of the economics of where the industry is going. And as I wrote about, I'm pretty concerned about that. And I think there's been a lot of complacency with that. As it relates to your other 2 levers, which is the liability level lever, like it doesn't make a difference. I mean it would be nice like our investment-grade spreads rally, they kind of trade somewhere between investment grade and high yield and they tightened by 20 to 30 basis points. But at 1:1 or 1.15x levered, it's not a real pickup in additional excess return to investors. And the last lever is obviously fees. And if the industry can't generate [indiscernible] ROE, capital will get reallocated or people will be forced to get more efficient, and that's the way capitalism works. I would point -- I wrote too long about this subject. I probably spoke too long about this subject on this call. But it is the right topic.
Unknown Analyst
AnalystsYes, I agree, and I share all of your concerns. That's why I asked. A couple of more questions, simpler ones. There was some migration in your internal risk ratings from 1 to 2. At a high level, can you tell us what drove that decline?
Robert Stanley
ExecutivesThere were -- so we had a couple of [ names ] that actually were lower rated that came off nonaccrual and moved up or were refinanced out. And then we had 2 specific names that went from 1 to 2. Those are businesses that are not performing to our original plan. However, they have strong interest coverage, and so we moved into 1 to 2, but the general trend was down a bit, but it was 2 specific names.
Unknown Analyst
AnalystsBut not -- I mean you're not seeing sort of that trend across the portfolio based on what I heard?
Robert Stanley
ExecutivesNo, in fact earnings for the quarter across the book were actually very strong quarter-over-quarter. I think [indiscernible], the earnings growth quarter over -- quarter-over-quarter. So when you look at Q1, our Q1 earnings 2025 over last year's earnings, they're up in the mid-teens, low to mid-teens on an earnings basis. On an LTM basis, they're around 8%. So the portfolio is in very good shape. These are 2 idiosyncratic names. And again, still performing, still have strong interest coverage. They're just -- they're not performing to our original plan.
Joshua Easterly
ExecutivesLook, I think I would say, generally, one of our big themes is -- we think we've been pretty good about [indiscernible], by the way. I just want to point it out to the team. But I think our -- the theme is that credit quality, we talked about this last quarter, probably quarters have kind of bottomed out. It probably slightly gets better, it slightly got better for us, at least on the nonaccrual line. And that now the focus is going to be to dividend coverage and which we think, for the first time between the combination of reinvestment spreads and the SOFR swap curve that there might be some dividend cuts in this space. Our dividend coverage happens to be really, really strong due to, a, we have excess economics in our book, and two, we size our dividend when we think about the liability. But like we think credit quality should -- like the economy is growing, credit quality should be pretty good. And so we feel pretty good about credit quality, but we think the shift should be focused now on ROEs and ROEs compared to the promises people made as it relates to the dividend.
Unknown Analyst
AnalystsYes, I agree with that as well. And I do expect to see some dividend cuts. My last question, just a housekeeping question, maybe for Ian. What was the nature of the increase in the prepaid expenses and other assets on the balance sheet? It moved pretty meaningfully. I suspect it might be a receivable for investments you sold?
Ian Simmonds
ExecutivesYes, that's right, Mickey. We had one name that paid off on June 30, but the cash didn't come in until post quarter end. So it was shown in the receivable rather than kept in the [ SOI. ]
Operator
OperatorOur next question comes from Finian O'Shea with Wells Fargo Securities.
Finian O'Shea
AnalystsI guess going back to the high level, Josh, I was interested in some of your opening remarks on credit. You described them as idiosyncratic, but also likely behind us. So I was wondering why idiosyncratic can mean a few things, basically one-off, but I would kind of think of it as coming from looser underwriting and seeing if you think that's something that's changed?
Joshua Easterly
ExecutivesYes. Look, we look at our book and say, things are mostly behind us or we think behind us. I would also say that when you look at the shock of the rate hike cycle in mid-2022, it takes -- there's a lag as it relates to defaults. That lag is a function of historically that companies have cash on their balance sheet and some flexibility to manage things. And so although there's a shock, there's a shock absorber, but that absorber gets worn out over time and shows up 2 years later. And so if you think about 2022, we're in mid-2025. I think generally, my feeling is like a lot of the credit issues have shown themselves. As it relates to what we call idiosyncratic, when you look at what we got wrong, what we got wrong was the -- specifically on Lithium was it was a business where it benefited from COVID. We clearly did not see that. And as the COVID kind of ran off and the industry structure in that business changed, we missed it. And so it wasn't generally because of high rates. It wasn't generally because of commodity prices. It was a very idiosyncratic credit issue with that business model.
Robert Stanley
ExecutivesYes. Finian, the only thing I'd say, we never compromise our underwriting standards, as you know, but we sometimes get things wrong. That's something we missed.
Finian O'Shea
AnalystsYes, no. Absolutely. And I was referring to the industry real large. I was interested in that. That makes sense. The answer is helpful. Just as a small follow-up, can you touch on the changes in the latest co-investment order and if the BDC still have priority on direct lending origination?
Joshua Easterly
ExecutivesYes, they do. I mean the co-investment [indiscernible] co-investment slightly, quite frankly, easier and more manageable. But yes, you will see nothing different.
Operator
OperatorOur next question comes from Kenneth Lee with RBC Capital Markets.
Kenneth Lee
AnalystsI think in the prepared remarks, you mentioned that about 30% of the originations in the quarter were driven by nonsponsored transactions. Wondering what your outlook is for the so-called Lane 2 and Lane 3 investments over the near term. Are you seeing more opportunities just given the macro backdrop?
Robert Stanley
ExecutivesYes, sure. I'll take that. So yes, this quarter, it was about 70% sponsored and 30% nonsponsored. That's fairly close to where our historical levels have been over time. It's usually about 65% sponsored and 35% nonsponsored. Some quarters like last quarter, you'll have more thematic nonsponsored coverage. We're -- I think, generally, we're generally positive in second half activity being stronger than it was last year given last year, the election cycle probably paused some demand. The pipeline feels pretty robust. Now it's a competitive environment, we're going to continue to be thoughtful on how we allocate capital. But we're seeing pretty strong demand across both sponsor and nonsponsor activity. So I'm not going to make a prediction on what that's going to look in the second half. It generally follows over the long arc of these, that 65-35. But we seem to be seeing good activity across each of our thematic areas.
Kenneth Lee
AnalystsGreat. Very helpful there. And just one follow-up, if I may. I think you touched upon this briefly. You mentioned the covenants and some of the documentation on new investments. Just curious, for the more recent new investments in the current environment, have you been seeing any kind of changes in terms and documentation?
Robert Stanley
ExecutivesWe have not seen a change over the last few quarters. And in fact, probably the last year in the document standards or covenant packages. They remain stable. I think in part because of how we source deals away from some of the more [indiscernible] areas, but we have not seen a change in that.
Operator
OperatorOur next question comes from Arren Cyganovich with Truist Securities.
Arren Cyganovich
AnalystsI was just wondering if you could talk a little bit about your thoughts on the push to open up retirement vehicles to private investment assets. And if you have any expectations to how that might impact the direct lending market.
Unknown Executive
ExecutivesYes. I mean I think it's a little too early to tell. I think it is -- I think it's a very complicated issue. I like the idea of giving access to returns and alternatives to individual investors. They've obviously had some of that through the BDC sector on the private credit side. To be honest, I'm a little concern, that the incentives are not exactly right and that there was a decent [ prophylactic ] around alternative where you had either super sophisticated individual investors or institutions that could do the work. And I'm a little concerned about their ability to do the work and individual investor protection. Hopefully, that gets cleared through and people are responsible in that way. I mean I can tell you, roll back 15 years when we started in the BDC industry and you talk to individual investors, I think this is not supposed to be snarky at all. But there was -- the vast majority did not understand the difference between return on capital and return of capital and dividend yield and ROE. And so there was a whole individual investor that was chasing high dividend paying stocks, not realizing that it was return of capital, not return on capital. And by the way, some of that still exists. And so the -- and the people on this call, which has been significant upgrading contribution to this space have been doing that work for -- on the research side to make sure that people understand that. But -- so I have mixed filings, I'm concerned. I understand why [ GPs ] want access because it's a big TAM and big growth. But at the end of the day, we got to take care of our clients and our job is to provide something of value of clients and not -- that focus still needs to be -- should remain, which is everything works well when you provide value to your customer, and the entire ecosystem takes care of itself. And I would urge the pace to keep that at the most -- as their North Star.
Arren Cyganovich
AnalystsGot it. That's helpful. And then just a quick one on new investments. There was an 8% stake in -- it looks like a structured credit. Can you maybe just talk a little bit about what that is and what kind of the underlying assets are in that?
Unknown Executive
ExecutivesYes. I'll hit that real quick. On occasion, we buy structured credit portfolio, which is of corporate loans, the underlined corporate loans and probably typically broadly syndicated loans and those securities or rated securities, typically BB or BBB, they offer competitive -- they offer competitive risk-adjusted returns with subordination. And so we've come in and out of that market through the years. So I think in -- and we sold a structured credit investments in Q2 that we bought for a price of [ 97.5 ] [indiscernible] that we sold for [ 102. ] I think. And so we've come in and out of that market.
Arren Cyganovich
AnalystsOkay. So these are just more opportunistic then?
Unknown Executive
ExecutivesYes.
Operator
OperatorOur next question comes from Melissa Wedel with JPMorgan.
Melissa Wedel
AnalystsI appreciate the context that you provided around sort of second half activity levels that you might expect to see. I'm curious if you're also expecting sort of repayment activity to remain elevated in the second half to sort of match that? Just note, looking at the net repayments over the last couple of quarters, they've been pretty sizable, and I know you don't manage to that necessarily on a quarterly basis, but just trying to put a framework around that.
Unknown Executive
ExecutivesYes. I mean, look, the good news, I think for SLX shareholders is that we have outsized exposure to vintages post '22 rate hiking cycle. So those were higher spread assets. As you know, how our accounting works is we don't recognize any of the upfront fee day 1, unless there's a syndication involved and they typically have call protection. So as those get called away from this early, they produce excess income. And so you have activity-based fees when repayments pick up. And so I would expect on the margin repayments to stay elevated, given that exposure that we have that others do not have or don't have as much of because we touched on investing through that rate hiking cycle. And so I think that in the short term is good for net investment income because there will be excess returns and fees. And then we're going to -- as I said at the end of our script, we got like -- we do it for a living. We have a large top of the funnel, and we'll go replace it with stuff we really, really like.
Melissa Wedel
AnalystsRight. Okay. And then I just wanted to follow up on sort of looking across the portfolio. Now that you've had a few more months after some tariff announcements. I'm just curious if you're still seeing low exposure across the portfolio. Have you rechanged on that at all?
Unknown Executive
ExecutivesNo. I mean. Look, I'll let Bo hit it. I think the answer is no. I think our tariff exposure is actually reduced post quarter end. But go ahead, Bo.
Robert Stanley
ExecutivesThat's exactly right. If you remember right, we had very low exposure, less than 1% of the portfolio on a fair market value basis. It was really 3 names that we thought had direct exposure. We didn't know exactly what the impact was going to be. Since last recording, actually one of the names -- one of those 3 names has actually been paid off. So we -- business was performing well, paid off into cheaper financing. So it's down to 2 small names at this point.
Operator
OperatorOur next question comes from Paul Johnson with KBW.
Paul Johnson
AnalystsCongrats on the good quarter. Can I just ask, so what drove the higher other income this quarter versus last? Was that just the repayment activity in the quarter?
Joshua Easterly
ExecutivesSorry, Paul. You cut out. I think the question was what drove higher other income?
Paul Johnson
AnalystsYes. Correct.
Ian Simmonds
ExecutivesYes. This is Ian. I'll take that one. It's really just a number of miscellaneous exit fees that are embedded in transactions that paid off during the quarter. [indiscernible]
Paul Johnson
AnalystsAnd sorry if I didn't catch it, but did you guys disclose what the prepayment income was, the accelerated prepayment income per share this quarter?
Ian Simmonds
ExecutivesFrom a per share basis, the prepayment income was about 1/3 of activity-based fees to around $0.06 per share was specific to prepayment funds.
Joshua Easterly
ExecutivesYes. I mean correct me if I'm wrong. In the other income line, there was exit fees, which is like a very close cousin prepayment funds. So the other income line was, how much?
Ian Simmonds
ExecutivesOther income was about $0.07 per share.
Joshua Easterly
ExecutivesYes. So I think it's fair to think of like prepayment and excess fees being pre -- on a gross basis, somewhere between $0.11 and $0.13 per share. They were pretty close cousins. The question -- the difference is technically is a prepayment income was existed in the contract from day 1 where an exit fee might have existed in the contract along the way, right, Ian?
Ian Simmonds
ExecutivesThat's right.
Paul Johnson
AnalystsOkay. Got it. That makes sense. Very helpful. And then in terms of -- sorry, go ahead. I don't know if I cut someone off there.
Unknown Executive
ExecutivesNo, no. I was about to say, they are the same thing. Go ahead.
Paul Johnson
AnalystsOkay. So in terms of the structuring fee income though, I mean, from the kind of sponsor portfolio optimization that you mentioned with some transactions or add-on activity there. Is there any sort of structuring fee income that would come along with that?
Unknown Executive
ExecutivesNo. I mean it may take a little bit of a deep dive on this because I think people in the industry do differ. So there are people in the industry that take some of their upfront fees and split it between a structuring fee and OID. And the issuer doesn't really care if the 2 points you get upfront and half of the structuring fee and half of OID. And ultimately, then what happens is, is that you have smaller OID that gets amortized over time. So something -- if you take more of the income upfront. And when something prepays, you have less accelerated OID because you've already taken the income. And that is not how we do our accounting. How we do our accounting, unless there is a syndication fee, we don't take a structuring fee. It all goes into OID. And so when the portfolio churns, there's more accelerated OID and there is -- then would have been a case if we took a structuring fee. So all of our fees are effectively deferred and put in OID at least from a structuring perspective. So people do it different. It's a really important nuance. So in the former case, new activity will drive NII on a marginal basis. In the latter case, our case is that repayment activity and portfolio churn will drive NII. Sorry for the deep dive.
Paul Johnson
AnalystsNo, I got it. That makes sense. And again, helpful answer there. Last one for me, just on the Lithium restructuring positive. That was done without any additional write-down or loss on the investment this quarter. But can I just ask, just on the earn-out securities. So what exactly, I guess, is kind of triggering the payout there based on revenue or EBITDA? Or is there any sort of sales that are taking place within the company? And also just kind of what's maybe the expected kind of realization time linethere? And that's all for me.
Unknown Executive
ExecutivesYes, sure. So again, this was split into 2 securities, which was an interest-earning debt security that is smaller and then an equity participation and all cash flows that are generated beyond that. The expectation is that the duration will be about 3 years to fully realize the value on that equity and there's a chance that we can overperform that. We took a view of what those cash flows would look like over the 3 years, and that's how we valued the equity security. They're loan amortized, right, Bo?
Robert Stanley
ExecutivesCorrect. Correct.
Operator
OperatorAnd our last question comes from Robert Dodd with Raymond James.
Robert Dodd
AnalystsCongrats on the quarter. If I can go to -- back to the repayment issue briefly, and then I've got a different one. To quote Ian, expect full year NII ROE and obviously [indiscernible] to be in the top half of previous guidance. But if fees remain elevated, could be above that. To quote Josh, expect repayments to remain elevated. And then if we look at your fair value to [indiscernible], which ticked up fairly meaningfully, this quarter tends to imply that you're expecting less core protection in certainly Q3, maybe the second half than you got in the first half or less of that's built into NAV. So can you reconcile, like you can have high payments without having high repayment fees, depending on the vintage of the asset, et cetera, et cetera. But can you kind of reconcile those bits and like if the repayments are elevated, why wouldn't fees be elevated, too? But that doesn't seem to be factored into your fair value to [indiscernible] ratio from the presentation.
Joshua Easterly
ExecutivesYes. So what I would say is, look, my comment as it relates to repayments as a Q3 look, Ian's comment was a full year look. So let's start with that, right? Like there is a -- Ian's talking about full year guidance, I was talking about in the next quarter. That's kind of what we have as much visibility as we have. And then obviously, fees and the amount of fees is a little bit of a function of what vintage, and we don't control that. But -- so I'm not sure there's a huge disconnect of what we all said. We're just trying to round it out.
Robert Dodd
AnalystsNo, no, no. I appreciate that. And that will breakdown those for me. On the second question, if I can, I mean, I was going to ask you about the [indiscernible] peak oil model, but something simple. To your point, Josh, typically balance sheet financials, you need an ROE greater balance sheet heavy financials. You need an ROE greater than 9% to trade at book or better. If institutional investors are the primary ones driving valuation. I think that's my addendum to that. So how do you think -- given a huge amount of capital raised, obviously, [indiscernible] the green funds, which are -- it is not institutional capital. So -- and obviously, those are for a lot of the market, the actual kind of drivers of spreads and volume more so than the public vehicles are. So how do you think to that point, like that 9%? Is that what the industry is going to be satisfied with given what the [ evergreen ] funds are doing and who the primary capital comes from on that spread?
Joshua Easterly
ExecutivesYes. I mean I'm a big believer that markets are typically not very efficient in the short term but very efficient in the long term. And what I would say is if you have an individual investor or an RIA who's sitting from that an individual investor, they should, at some point, are going to pick their head up and say, I can earn -- I can buy something at a discount to book in the public markets and earn a 9% versus buying something at par and have daily liquidity versus buying something at NAV and rebuy [indiscernible] not redeeming the [indiscernible], and that may or may not have liquidity when I put it at the end of the quarter, like that will work its way through if people are doing their job as fiduciaries. And so in the short term, that disconnect might exist. But in the long term, my hope and belief, if markets are doing their job and people are active fiduciaries, they will put their clients on the best risk-adjusted return on capital and look at alternatives and look at liquidity premiums and optionality and discounts to book and all that stuff. So I think ultimately, it will come out in the wash. You would, I think all things being equal, were to own something where you have daily liquidity versus not and where you might dictate it. And that -- people have to experience that firsthand to kind of realize it. But at some point, they will and will work its way through.
Operator
OperatorAt this time, I'd like to turn the call back over to Josh Easterly for closing remarks.
Joshua Easterly
ExecutivesLook, two things. Look, we live in -- the teams in New York City most, of us live in New York City, except for [indiscernible] and Cami. And I would say, it's hard not to end any type of call this week without saying that it is -- life is fragile and random. And like what happened this week was on nobody's [indiscernible] board and people should make sure they are present with the people they care about and give them lots of hugs. So I will say that because that's top of mind for me. Another thing that's top of mind for me is I look back at what Sixth Street Specialty Lending has accomplished, prepublic and post public since 2014. And it's about the team. The team has just done an incredible job over market cycles, navigating difficult times, and I couldn't be prouder of the people that I work with, and the platform is a special place where we have the ability to really find unique investments for our investors with the big top of the funnel, and it's a pleasure working with the people I work with. So those 2 things are top of mind to me. And I thank everybody for attending the call, and I hope people have a peaceful rest of the summer. Thanks, everyone.
