The directors to be replaced are: Afif Demirkıran, Nail Olpak, Hüseyin Arslan and Sir Julian Horn-Smith (the “Non-TWF Directors”). On January 4, 2022, IMTIS Holdings delivered a letter to the Issuer requesting that, among other things, (i) the independence of the Independent Director Candidates be immediately assessed by the Nomination Committee of the Board in accordance with the Issuer’s articles of association and applicable law, (ii) the Board approve and submit to the Capital Markets Board of Turkey an independent director candidate list comprising the Independent Director Candidates by no later than January 26, 2022, and (iii) the Board take, or cause to be taken, all actions and do, or cause to be done, all things, necessary, proper or advisable to make effective, as promptly as practicable, the nomination and the appointment to the Board of the Director Candidates, including by way of (a) adopting a Board resolution to convene a general assembly meeting with an agenda that will include a clear item for dismissing the Non-TWF Directors and replacing them with the Director Candidates, in each case serving for a term of one year expiring on the date of the annual general assembly of shareholders approving the financial statements of the Issuer for the fiscal year ending December 31, 2022, and (b) preparing and disclosing the information document and any other documents that may be required to adequately and timely inform the Issuer’s shareholders of the relevant agenda items, including the identity and qualification of the Director Candidates. IMTIS Holdings intends to submit in due course to the next general assembly of shareholders further resolution proposals which will address other concerns raised in the letter sent by IMTIS and L1T UB Holdings to the Board on October 28, 2021.

The Reporting Persons have had and anticipate having further discussions with officers and directors of the Issuer regarding various strategic and operational initiatives that the Reporting Persons believe can generate value. The topics of these discussions have covered and will cover a range of issues, including recommendations relating to the business of the Issuer, management, board composition, investor communications, operations, capital allocation, dividend policy, financial condition, mergers and acquisitions strategy, overall business strategy, executive compensation, corporate governance and environmental and social matters related to the Issuer’s business and stakeholders. The Reporting Persons may also have similar discussions with other stockholders or other interested parties, such as industry analysts, existing or potential strategic partners or competitors, investment professionals and other investors.

The Reporting Persons intend to review their investment in the Issuer on a continuing basis. Depending on various factors including, without limitation, the Issuer’s financial position, results and strategic direction, price levels of the Shares, the outcome of any discussions referenced above, actions taken by management and the Board, the Reporting Persons’ overall investment strategies and liquidity requirements, applicable legal and regulatory constraints, conditions in the securities and capital markets, and other factors that the Reporting Persons may deem relevant, the Reporting Persons may in the future consider various courses of action of the types described in paragraphs (a) through (j) of Item 4 of Schedule 13D.

Item 5 of the Statement is hereby amended as follows:

The responses of the Reporting Persons to Rows (7) through (13) of the cover pages of this Schedule 13D and the information set forth in Item 4 are hereby incorporated by reference in this Item 5.

(a) In its capacity as sole shareholder of IMTIS Holdings, IMTIS may be deemed to be the beneficial owner of the 435,600,000 Shares held by IMTIS Holdings, cumulatively representing 19.8% of the issued and outstanding Shares. IMTIS Holdings is the owner of the 435,600,000 Shares.

By virtue of its direct ownership of the 435,600,000 Shares, IMTIS Holdings has the shared power to vote or direct the vote, and shared power to dispose or direct the disposition of, such Shares.

(c) To the best of the Reporting Persons’ knowledge, there have been no transactions effected with respect to any Shares during the past 60 days by any of the persons named in response to Item 2.

CUSIP No. 900111204	Schedule 13D/A	Page 12 of 14 Pages

Each such Reporting Person disclaims beneficial ownership of the securities reported herein, and neither the filing of this Amendment nor any of its content shall be construed as an admission of such beneficial ownership or that such Reporting Persons constitute a person or group.
