 each instance, we refer you to the copy of such contract, agreement or document filed as an exhibit to the registration statement, with each such statement being qualified in all respects by reference to the document to which it refers.

We are subject to the informational requirements of the Exchange Act. Accordingly, we file periodic reports and other information with the SEC. You may obtain copies of all or any part of these materials from at no cost from the SEC’s website at www.sec.gov and our website at www.aspen.co.

### INCORPORATION OF CERTAIN DOCUMENTS BY REFERENCE
We file annual reports, periodic reports and other information with the SEC. The SEC allows us to “incorporate by reference” the information we file with it, which means that we can disclose important information to you by referring to those documents. The information incorporated by reference is an important part of this Prospectus. Each document incorporated by reference is current only as of the date of such document, and the incorporation by reference of such documents shall not create any implication that there has been no change in our affairs since the date thereof or that the information contained therein is current as of any time subsequent to its date. The information incorporated by reference is considered to be a part of this Prospectus and should be read with the same care. Any statement contained in a document which is incorporated by reference in this Prospectus is automatically updated and superseded if information contained in this Prospectus, or information that we later file with the SEC, modifies or replaces this information.

We incorporate by reference the documents listed below (other than portions of these documents that are furnished under applicable SEC rules rather than filed and exhibits furnished in connection with such items, except as otherwise noted):

(1) our Annual Report on Form 20-F for the year ended December 31, 2022 filed with the SEC on April 20, 2023; and

(2) our Current Reports on Form 6-K filed with the SEC on March 1, 2023 (including Exhibit 99.1 furnished therewith), June 1, 2023 (including Exhibit 99.1 furnished therewith) and June 13, 2023 (including Exhibit 99.1 furnished therewith).

All documents we file pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act after the initial filing of this registration statement and after the date of
