**PART III — NARRATIVE** 

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-CEN, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

The Company has encountered delays in filing its Quarterly Report on Form 10-Q for the quarter ended September 30, 2025, within the prescribed timeframe. The Company requires additional time to finalize required information. Eliminating the delay would require an unreasonable level of effort or expense.

**PART IV — OTHER INFORMATION** 

(1)Name and telephone number of person to contact in regard to this notification

Debra DeFelice (212) 447-1000 <br> (Name) (Area Code) (Telephone Number)

(2)Have all other periodic reports required under Section 13 or 15(d) of the Securities Exchange Act of 1934 or Section 30 of the Investment Company Act of 1940 during the preceding 12 months or for such shorter period that the registrant was required to file such report(s) been filed? If answer is no, identify report(s). ⌧ Yes ☐ No

(3)Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof?

⌧ Yes ☐ No

If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.

The Company currently expects net revenues for the third quarter of 2025 to increase approximately 19% compared to the third quarter of 2024, driven primarily by growth in digital revenue. The Company also expects its net loss for the third quarter of 2025 to increase approximately 130% compared to the prior-year period, largely due to the mark-to-market fair value adjustment on outstanding warrants.
