NKGen Biotech ( (NKGN) ) just unveiled an announcement.
On February 20, 2026, NKGen Biotech, Inc. and its subsidiary NKGen Operating Biotech, Inc. entered into a fourth amendment to their secured promissory note with AlpineBrook Capital GP I Limited, adding a further $343,000 in funding. This amendment increased the principal on the note to $27,101,106 and specified that interest on the new tranche accrues from February 20, 2026, underscoring NKGen’s continued dependence on incremental debt financing to fund its ongoing operations.
The additional capital from AlpineBrook represents another short-term liquidity boost following several amendments to the original January 2026 note. This pattern of successive funding increases may signal both the company’s near-term cash needs and AlpineBrook’s ongoing willingness to provide credit support, developments that are likely to be closely watched by investors and other stakeholders tracking NKGen’s financial runway.
