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.

NLS Pharmaceutics Ltd.
(the “Company”) was unable, without unreasonable effort or expense, to file its Annual Report on Form 20-F for the year ended
December 31, 2024 (the “Annual Report”) by the prescribed due date for the reasons described below.

The Company requires additional time to prepare and review its financial statements for the year ended December 31, 2024, and have such
financial statements audited. Factors which have affected the timing of the preparation and review of the financial statements include
(i) the continued attempts to consummate a merger with Kadimastem Ltd., and (ii) the Company recently raising up to $3 million and signing
a $25 million committed equity facility agreement as part of the planned strategic merger with Kadimastem Ltd.

As a result of the foregoing, the Company is unable, without unreasonable
effort or expense, to file its Annual Report by the prescribed due date of April 30, 2025. The Company is working diligently to complete
the Form 20-F as soon as possible.

The Company currently expects to file the
Annual Report within the 15 calendar day extension period provided by Rule 12b-25.
