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.

Sustainable Development Acquisition I Corp. (the “Company”) has determined that it is unable, without unreasonable effort or expense, to file its Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2021 (the “Q1 2021 Form 10-Q”) by the prescribed due date for the reasons described below.

On April 12, 2021, the Acting Director of the Division of Corporation Finance and Acting Chief Accountant of the Securities and Exchange Commission together issued a statement regarding the accounting and reporting considerations for warrants issued by special purpose acquisition companies entitled “Staff Statement on Accounting and Reporting Considerations for Warrants Issued by Special Purpose Acquisition Companies” (the “SEC Statement”). As a result of the SEC Statement, the Company’s management reevaluated the accounting treatment of our outstanding warrants issued in connection with our initial public offering on February 9, 2021, including the 9,325,000 private placement warrants issued to Sustainable Development Sponsor, LLC (our sponsor) and the 15,812,500 warrants issued as part of the units sold in our initial public offering, each with an exercise price of $11.50 (the “Warrants”), in accordance with Accounting Standards Codification (“ASC”) 815-40, Derivatives and Hedging: Contracts in an Entities Own Equity. ASC 815-40 states entities must consider whether to classify contracts that may be settled in its own stock, such as warrants, as equity of the entity or as an asset or liability. The Company previously accounted for the Warrants as components of equity.

After consideration of the guidance in the SEC Statement, the Company concluded that the Warrants should be accounted for as a liability and measured at fair value with changes in fair value each period reported in the Company’s statement of operations. The Company is in the process of completing its final analysis of this change.

The Company is working diligently to complete the Q1 2021 Form 10-Q as soon as possible; however, given the scope of the process for determining the appropriate treatment of the Warrants in accordance with the SEC Statement and ASC 815-40, the Company is unable to complete and file the Q1 2021 Form 10-Q by the required due date of May 17, 2021 without unreasonable effort and expense. The Company does, however, expect to file such report within five calendar days thereof.
