EXPLANATORY NOTE/DEREGISTRATION OF SECURITIES
This Post-Effective
Amendment (the “Post-Effective Amendment”), filed by Rubicon Technology, Inc., a Delaware corporation (the
“Company”), and Rubicon Worldwide LLC, as subsidiary guarantor of debt securities of the Company (the “Subsidiary
Guarantor,” and together with the Company, the “Registrants”), relates to the Registration Statement on Form S-3
(File Nos. 333-192536 and 333-192536-01), registering, among other securities, $40,000,000 of shares of the Company’s common stock, par
value $0.001 per share (the “Shares”), held by the selling stockholders named therein, which was filed with the
Securities and Exchange Commission (the “Commission”) on November 25, 2013, as amended by Amendment No. 1, filed with
the Commission on December 6, 2013 (the “Prior Registration Statement”).
On December 13, 2022, the Company announced that it
notified The Nasdaq Stock Market LLC (“Nasdaq”) of its intention to delist the Shares from Nasdaq. On December 23, 2022, the
Company filed a Form 25 to delist the Shares from Nasdaq. On March 10, 2023, the Company decided to voluntarily deregister from the reporting
requirements under the Securities Exchange Act of 1934, as amended, with the Commission. In connection with the Company’s voluntary
decision to delist and deregister, the Registrants have terminated any and all offerings pursuant to the Prior Registration Statement.
Accordingly, the filing of this Post-Effective Amendment is made pursuant to an undertaking made by the Registrants in Part II of the
Prior Registration Statement to remove from registration by means of a post-effective amendment any securities that had been registered
for issuance but remain unsold at the termination of the offering. The Registrants, by filing this Post-Effective Amendment, hereby remove
from registration any and all securities registered but unsold under the Prior Registration Statement as of the date hereof. The Prior
Registration Statement is hereby amended, as appropriate, to reflect the deregistration of such securities.

of 1933, as amended, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing
