CION: Is NAV Erosion Mostly Mark-To-Market, Or A Sign The Book Is Becoming More Equity-Like
CION's 2025 NAV erosion does not read like a broad collapse of the whole portfolio, but it is also hard to dismiss as temporary mark noise. The quarterly pattern was lumpy, yet the book also shifted toward less plain lending and more equity, affiliated investments, and controlled positions.
Why This Needs Its Own Follow-Up
The main article argued that CION entered 2026 with an income engine that still works, but with NAV under pressure and financing that mainly bought time. This continuation isolates one narrower question: was the 2025 NAV damage mostly a temporary valuation event inside a still largely senior book, or did it reveal a deeper change in what the portfolio has become, less plain first-lien lending and more equity-like, influence-heavy exposure.
The filings point to a split verdict. This was not a portfolio-wide collapse, but it was not just a one-off marking accident either. The quarterly loss pattern was lumpy and the risk-rating table does not suggest broad disintegration. At the same time, the portfolio mix moved in a less conservative direction, and the 2025 damage did not sit only in the equity tail. It also landed in the core first-lien book.
Four facts reconcile the debate:
- First and second lien exposure fell to 80.8% of the portfolio at year-end 2025 from 86.1% a year earlier, while equity rose to 18.5% from 13.2%.
- Affiliated and controlled investments rose to $654.0 million, 38.5% of the portfolio, from $440.6 million, 24.2% of the portfolio, at year-end 2024.
- Risk ratings do not show a broad break, but they did drift modestly the wrong way: ratings 4 and 5 rose to 2.4% from 1.6%, and Non-Accruals increased to 1.78% from 1.40%.
- Inside the Level 3 reconciliation, first-lien debt alone absorbed $111.8 million of realized loss and unrealized depreciation in 2025. The damage was not confined to the equity edge of the book.
What Actually Changed In The Portfolio
Less plain lending, more equity exposure
The first change is structural, not just accounting. At year-end 2025, CION's portfolio stood at $1.697 billion at fair value versus $1.820 billion a year earlier. Within that total, first and second lien loans fell to $1.371 billion, while equity rose to $314.8 million. That does not mean CION suddenly became an equity fund. It does mean the book moved farther away from a plain senior-lending portfolio.
That shift matters because it changes how NAV should be interpreted. A portfolio dominated by plain senior loans can suffer through a weak quarter and still be read as temporarily marked. A portfolio where the equity bucket expands by more than $75 million in one year, while senior loan exposure falls by more than $195 million, depends more on realizations, restructurings, and valuation judgment.
More affiliated and controlled exposure
This is the hardest part of the story to dismiss as noise. Non-controlled affiliated investments rose to $364.3 million from $269.2 million, and controlled investments rose to $289.7 million from $171.4 million. Together, those two categories reached $654.0 million.
| Exposure layer | Fair value 2025 | Fair value 2024 | Share of portfolio 2025 | Share of portfolio 2024 |
|---|---|---|---|---|
| Non-controlled affiliated investments | $364.3 million | $269.2 million | 21.5% | 14.8% |
| Controlled investments | $289.7 million | $171.4 million | 17.1% | 9.4% |
| Combined | $654.0 million | $440.6 million | 38.5% | 24.2% |
That is not cosmetic. Economically, a book where almost 39% of portfolio value sits in affiliated or controlled positions is a book where NAV depends more on control structures, restructurings, internal marks, and whether the lender is increasingly becoming the owner in substance. That is exactly the direction that makes the portfolio more equity-like and less purely loan-like, even if part of the exposure still sits in debt instruments on paper.
The income line is less clean than it first looks
Another reason the NAV debate cannot be settled by NII alone is the composition of investment income. Out of $240.8 million of total investment income in 2025, $163.2 million came from interest income, $49.2 million from PIK, $20.1 million from fees, and $8.3 million from dividends. In other words, about 32% of investment income did not come from ordinary interest income.
That does not prove the book is impaired. It does explain why positive NII can coexist with weaker NAV. When more of the income line relies on PIK, fees, and dividends, it looks less like a plain cash-coupon senior-loan book and more like a portfolio whose economics depend on restructurings, workout outcomes, and the valuation of equity-linked positions.
Where The Damage Actually Landed
One easy reading would be that CION simply built a larger equity bucket and then that bucket got marked down. That is not what the numbers show. Nearly all of the portfolio, $1.677 billion out of $1.697 billion, sat in Level 3 at year-end 2025, so some mark-to-model noise is built in by definition. But once the 2025 valuation move is broken down by asset type, the main hit sits in first-lien debt.
That changes the interpretation of 2025. Inside the Level 3 book, first-lien debt absorbed $35.5 million of realized losses and another $76.3 million of unrealized depreciation. Equity, by contrast, showed only a $0.5 million realized loss and an $8.6 million unrealized appreciation. So even if the portfolio mix became more equity-like, 2025 was not simply an equity accident. The pressure also hit the part of the portfolio that was supposed to be more defensive.
That is also why the income-to-equity bridge matters. In 2025, CION still generated $93.0 million of after-tax NII, but realized and unrealized losses reached $113.7 million. Operations therefore reduced equity by $20.6 million before distributions and before share repurchases. The statement that income still held is true. It just was not enough to protect NAV.
What The Ratings And The Quarterly Pattern Say
Anyone arguing that the book fully broke runs into one problem: the risk-rating table does not look like that. At Q4 2025, 86.1% of the portfolio still sat in internal ratings 1 and 2. Rating 1 even rose to 8.2% from 2.0% a year earlier. That is not what a broad portfolio collapse looks like.
But the lower-quality tail did worsen:
| Credit-quality marker | Q4 2025 | Q4 2024 | Change |
|---|---|---|---|
| Ratings 1 and 2 | 86.1% | 87.8% | down 1.7 percentage points |
| Rating 3 | 11.5% | 10.6% | up 0.9 percentage points |
| Ratings 4 and 5 | 2.4% | 1.6% | up 0.8 percentage points |
| Non-Accrual | 1.78% | 1.40% | up 0.38 percentage points |
That is exactly why the right reading is neither "everything is fine" nor "everything is broken." The top of the rating table still holds most of the book, but the stressed tail is getting slightly longer and Non-Accruals are not moving the right way.
The quarterly pattern reinforces the same conclusion. The realized and unrealized losses of 2025 did not come in a straight line. They arrived in two sharp waves, Q1 and Q4.
Q1 and Q4 together produced $121.4 million of realized and unrealized losses, while Q2 and Q3 together generated only a $7.7 million net gain in that same line. That is why the mark-to-market reading is not unreasonable. The damage was lumpy, not linear. But it does not stand alone. By year-end, it sits next to a larger equity bucket, more affiliated and controlled exposure, and mild but visible slippage in the quality tail. That makes it difficult to argue that this was only a passing quarter-end mark that will simply reverse by itself.
Conclusion
The right decomposition of 2025 is this: the valuation component was real, but the structural component was also real. Anyone looking only at the risk-rating table can argue that the book is still far from a broad collapse. Anyone looking only at NAV can argue that the portfolio already broke. Both miss the middle.
CION finished the year with a portfolio that looks less like a plain senior-loan book and more like a credit platform where a larger share of value depends on affiliated positions, control, PIK, and workout execution. At the same time, the main damage of 2025 still sat in first-lien debt, which means the problem was not limited to the equity fringe of the book.
That is exactly what 2026 has to test. If senior-loan share stabilizes, affiliated and controlled exposure stop climbing, and Q4 proves to be episodic rather than the start of a new pattern, the "mostly mark-to-market" thesis can recover. If not, the market will keep reading NAV erosion as evidence that the book has become less loan-like, less simple, and more dependent on valuation judgment and restructurings.
