On January 15, 2026, ImmunityBio, Inc. (the “Company”) issued a press release announcing certain preliminary, unaudited financial results for the fiscal quarter and full year ending December 31, 2025, along with additional Company updates. The results included in the press release reflect the Company’s preliminary estimates based solely upon information available to it as of the date of the press release, and the amounts reported are not a comprehensive statement of its operating results or financial position as of December 31, 2025. Any actual amounts that the Company reports in its Annual Report on Form 10-K for the year ended December 31, 2025 will be subject to its financial closing procedures and any final adjustments that may be made prior to the time its operating results and financial position for the fiscal quarter and year ended December 31, 2025 are finalized. As a result, these preliminary estimates may differ materially from the actual results that will be reflected in the Company’s consolidated financial statements for the fiscal year ended December 31, 2025 when they are completed and publicly disclosed in its Annual Report on Form 10-K. The full text of the Company’s press release is furnished as Exhibit 99.1 hereto. The information furnished pursuant to Item 2.02 of this Current Report on Form 8-K (including Exhibit 99.1) shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall such information be deemed incorporated by reference into any filings of the Company made under the Exchange Act or the Securities Act of 1933, as amended, whether made before or after the date of this Current Report, regardless of any general incorporation language of such filing, except as shall be expressly set forth by specific reference in such filing.
