Flat Rock Core Income Fund (CORFX): Repurchases, NAV, Payout

What CORFX is, and where it came from

Flat Rock Core Income Fund is a continuously offered interval fund run by Flat Rock Global, LLC of Jackson, Wyoming, whose chief executive officer, Robert K. Grunewald, signs the fund’s filings. It has one class of shares, ticker CORFX, with no sales load and no early withdrawal charge. The prospectus says “The Fund does not have a required minimum initial or subsequent investment amount.” It pays distributions monthly and reinvests them unless a holder opts out.

It is not a new vehicle. The fund “acquired all of the assets and liabilities and adopted the performance history of Flat Rock Capital Corp.” on November 20, 2020. Flat Rock Capital Corp. was a business development company, and the 2020 reorganization papers say the adviser would bear the reorganization costs and that stockholders would receive fund shares in proportion to their holdings. That is why the fund’s performance record runs back to 2017 while its repurchase filings start in December 2020. Two sister funds, Flat Rock Opportunity Fund (FROPX) and Flat Rock Enhanced Income Fund (FRBBX), share the adviser; the board told shareholders the adviser managed over $1.6 billion across three interval funds at December 31, 2025. On September 15, 2026 the fund named a new chief financial officer, Michael Stewart, after Ryan Ripp resigned from the role (supplement filed that day). For the funds side by side see the list of interval funds.

The offer open now: what a holder can do before October 23, 2026

The notice words the extra-2% rule this way: “If shareholders tender for repurchase more than the Repurchase Offer Amount, the Fund may, but is not required to, repurchase an additional amount of shares not to exceed 2% of the outstanding shares of the Fund on the Repurchase Request Deadline.” It also says “The Fund will not charge a repurchase fee.” At the July 2026 size, 5% was about $14.5 million, and the fund’s own words on the overall limit are that repurchase offers above 5% “are made solely at the discretion of the Board.”

Twenty-three offers: six above 5%, the last three at the line

Each offer is reported in the repurchase note of an annual or semiannual report as an amount and a number of shares; the three most recent are in the June 2026 semiannual report. The price is the amount divided by the shares (our arithmetic). The last column divides the amount by net assets at the preceding quarter-end from Form N-PORT (our arithmetic); the fund does not report the percentage of shares bought, and sales between the quarter-end and the pricing date make small differences.

Three things stand out. First, from 2021 through 2024 purchases were mostly small: ten of the sixteen offers were under 3.5% of net assets, and the largest were January and April 2023, at 7.15% and 6.83%, close to the 7% ceiling (the 5% offer plus the extra 2%). Second, in 2025 the fund stepped up: $73.9 million repurchased in four offers, 24.6% of the $300.0 million of net assets at the end of 2024 (our arithmetic), with April, July and October each above the 5% offer. Third, since January 2026 the fund has bought 5.04% to 5.05% three times in a row, which is the 5% offer rather than the extra 2%. That pattern fits requests at or above 5%, but the filings never say how much was tendered, so a holder cannot tell from them whether a request was filled in full. Small differences exist between the semiannual and annual reports for the same offer (for example $3,195,115 against $3,195,319 for January 2022); the table uses the annual report.

Money in, money out: sales dried up while repurchases doubled

From 2021 to 2024 the fund grew by selling shares faster than it repurchased them. In the first half of 2026 the order reversed: $13.9 million came in, $1.6 million was reinvested distributions and $30.5 million left, a net outflow of about $15.0 million (the report’s own total is $14,980,580). Form N-PORT shows the same slope in net assets at each quarter-end: $323.6 million at June 30, 2025, $319.2 million at September 30, $308.4 million at December 31, $295.5 million at March 31, 2026 and $286.9 million at June 30, 2026, an 11.3% fall in a year (our arithmetic). In 2025 capital share transactions were still a net inflow of $22.0 million (the report’s total is $22,013,488), which is why net assets held at $308.1 million at year-end.

NAV: $20.72 in June 2024, $19.11 in September 2026

Every offer notice quotes the NAV a week before the offer opens. Read together they show a fund that held about $20.00 to $20.70 through 2021-2024 and has slid since mid-2024.

The fund keeps two NAVs. The one used for buying and repurchasing shares is calculated daily; the one in the audited statements can differ because of accounting adjustments, and the report says returns on the transaction NAV “may differ from the return shown in the Financial Highlights.” The reported NAV was $20.53 on December 31, 2024, $19.62 on December 31, 2025 and $19.20 on June 30, 2026. On the transaction NAV the fund returned 5.57% in 2025 and 5.66% in the year to June 30, 2026, against a payout of roughly 9.4% a year (see below). The shareholder letter for 2025 says the fund paid $1.97 per share in dividends and “experienced a $0.88 decline in net asset value” during the year, and names the cause: “The largest drivers of CORFX’s NAV decline were a litigation finance loan and a collateralized loan obligation” managed by BlackRock. The letter does not name the loan.

The payout: income covered 87% of distributions in 2026

Net investment income per share is on average shares outstanding, so the ratios below are approximate (our arithmetic). The tax-character table shows all of 2025’s $30,483,029 of distributions as ordinary income, none as return of capital.

In dollars, net investment income was $12,215,530 against $13,849,098 of distributions in the first half of 2026 (88%, our arithmetic), and $26,382,645 against $30,483,029 in 2025 (87%). Realized losses on sales added to the gap: $7,192,880 in six months, equal to 59% of net investment income (our arithmetic). The filings show two cuts to the monthly distribution. The 2025 letter says the board approved a reduction “from $0.165 to $0.155 per share” in September 2025 because SOFR had declined from 4.3% to 3.7%, and puts the distribution rate at 9.46% at year-end. The semiannual report lists $0.155 for January and February 2026 and $0.150 for July and August 2026; six months of $0.155 is the $0.93 paid in the half (our arithmetic), so the second cut came in July. At $0.150 a month and the September 11 NAV of $19.11, the annualized rate is 9.4% (our arithmetic). A payout above net investment income, with a falling NAV, means the distribution is not being earned from income alone; the prospectus risk language says distributions “may be funded from unlimited amounts of offering proceeds or borrowings.”

The adviser paid in $7.2 million and waived $1.2 million: what it did to the numbers

Two adviser payments sit behind the 2025 results. In 2025 “the Adviser elected to reimburse the Fund for investment losses, totaling $7,236,544,” booked as “Contribution from affiliate.” That is $0.46 a share: without it, the report says, the 2025 total return would have been 3.21% rather than 5.41%, and the year-end NAV $19.16 rather than $19.62 (our arithmetic). The filings do not say which investments the money covered. Separately the adviser waived $1,231,118 of management fees in 2025 and $189,344 in 2024.

Ratios are to average net assets including interest and preferred dividends. In the first half of 2026 the two ratios are identical, and the semiannual report shows no waiver and no affiliate contribution. The board noted at its February 2026 review that “due to a large fee waiver, the Adviser did not profit from its relationship with the Fund during 2025.” Whether the support continues is not stated anywhere: the prospectus says “The waiver is not contractual and may be terminated at any time. Additionally, the waiver is permanent, and any fees waived and/or expenses reimbursed may not be recouped by the Adviser.” So there is no expense limitation agreement and nothing for the adviser to claw back later, but also no commitment to keep waiving.

What the adviser is paid

Management and incentive fees together were $4,041,928 in the first half of 2026, 20.8% of total investment income of $19,405,958 (our arithmetic). The incentive fee is on income, not total return: the fund says pre-incentive fee net investment income “does not include any realized capital gains, realized capital losses or unrealized capital appreciation or depreciation,” so the adviser was paid $2.0 million of incentive fees in a half-year when the fund realized $7.2 million of losses. Until June 30, 2026 the hurdle was measured on “adjusted capital” (cumulative proceeds from share sales less repurchase payments); effective July 1, 2026 it is measured on NAV, a change the board considered “economically neutral.” The 1.02% of acquired fund fees in the fee table is a cost that does not appear in the fund’s own expense ratio: it is charged inside the private funds the fund owns.

What it owns: half CLO debt, half first-lien loans, and four positions flagged in default

The fund is a CLO buyer, but not mainly of equity: CLO equity is 5.75% of net assets, down from $27.3 million at the end of 2024 to $16.5 million, while CLO debt, which the prospectus describes as the junior debt tranches of CLOs, is 48.86%. In six months the fund bought $30.6 million of CLO debt and sold or was paid down $43.6 million of first-lien loans (note 3 roll-forward). The 2025 letter explains the tilt: the manager “identified more attractive relative value in private credit CLOs” whose debt tranches were initially rated BB, and says such tranches were being issued at about SOFR plus 7.00% against about SOFR plus 4.75% for core direct lending loans. The portfolio is 123.90% of net assets because it is levered. Almost none of it has a market price: $315.4 million is valued with Level 3 inputs, $40.0 million at private-fund NAV, and the only Level 1 holding is $100,255 of money market fund. Restricted securities are 61.51% of net assets.

The largest ten positions at June 30, 2026 were 34.55% of net assets (our sum): Hercules Private Global Venture Growth Fund I LP (6.50%), TriplePoint Private Venture Credit, Inc. (4.92%), Fortress Credit Opportunities XXI CLO (3.48%), New Mountain Guardian IV Rated Feeder III (3.36%), Monroe Capital ABS Funding II (3.22%), Xenon Arc term loan (2.70%), Vehicle Management Services term loan (2.64%), Fortress Credit Opportunities XIX CLO (2.63%), Crane Engineering Sales term loan (2.58%) and BCP Great Lakes II Series B (2.52%). The first two follow venture-lending strategies according to the fund’s notes, 11.4% of net assets together (our sum), a different risk from the middle-market senior loans the prospectus describes as the primary strategy.

The fund’s semiannual report does not say which loans are non-performing. Its Form N-PORT for June 30, 2026 flags four positions as in default: the Diversified Risk Holdings term loan ($5.10 million at fair value), a funded revolver ($0.13 million) and an unfunded revolver ($0.15 million) with the same borrower, and the Watterson term loan ($3.31 million). The three funded positions are $8.53 million, 2.97% of net assets (our sum). At December 31, 2025 the same report flagged three Solaray term loans instead; they are not flagged at June 30, 2026.

Leverage: a $56.1 million credit line and a $10 million preferred due September 15, 2026

The preferred stock is the one dated event on the balance sheet: its stated redemption date passed on September 15, 2026, after the last semiannual report. None of the filings we read through October 9, 2026 shows how it was redeemed or replaced; the next Form N-PORT, for September 30, 2026, is due by late November. The prospectus adds that on May 12, 2026 the fund received a new SEC co-investment order, which lets it negotiate terms other than price and quantity in co-investment transactions with other funds managed by the adviser or certain affiliates, including the two sister funds.

What a holder can do with this

• If you want out: the request goes to the transfer agent (Ultimus) or through your adviser or broker by 4:00 p.m. Eastern on October 23, 2026, and can be withdrawn until then. Payment comes within seven days of the pricing date. If requests exceed the offer, expect pro rata treatment; shares not accepted must be resubmitted in the next offer, expected in January 2027.
• If you are staying: the annual report for 2026, due around March 2027, will list the October 2026 result and show whether the payout still exceeds income; the Form N-PORT for September 30, 2026, due by late November, will show net assets and borrowings. The signals are the amount repurchased against the roughly $14.5 million of a 5% offer, and whether anything like the 2025 adviser contribution of $0.46 a share repeats.
• What would change the picture: net sales turning positive again, income covering the $0.150 monthly payout, or the CLO debt book repricing. A NAV that keeps falling while the payout stays near 9.4% is the case to watch.
• If it is a large part of your portfolio: position size and the 5% quarterly valve are the issue, not the headline yield. A screened adviser can run the numbers on your own tax situation.

Other funds in the same position are in the private credit redemptions tracker and the evergreen funds compared; a larger interval fund with the same 5% structure is Cliffwater Corporate Lending Fund.
