SCHEDULE 13D/A4

This constitutes Amendment No. 4 (the “ Amendment No. 4 ”) to the statement on Schedule 13D filed on behalf of Karen Singer, dated and filed December 15, 2017 (as amended, the “ Statement ”), relating to the common stock, $0.01 par value per share (the “ Common Stock ” or “ Shares ”), of Alaska Communications Systems Group, Inc. (the “ Company ” or the “ Issuer ”). Unless specifically amended or modified hereby, the disclosure set forth in the Statement shall remain unchanged.

Item 4 of the Statement is hereby amended to add the following:

On February 9, 2018, TAR Holdings delivered an advance notice to the Issuer nominating a slate of three highly qualified director candidates, including Steven G. Singer, Wayne Barr, Jr. and Patrick F. Doyle (collectively, the “ Nominees ”), for election to the Board at the Issuer’s 2018 annual meeting of stockholders (the “ Annual Meeting ”). The Reporting Person believes that significant change to the composition of the Board is warranted given, among other things, (i) the significant underperformance of the Issuer, (ii) the recent actions taken by the Board and management which are clearly designed to entrench themselves to the detriment of the Issuer’s stockholders (including the purported adoption by the Issuer of those certain Amended and Restated Bylaws on December 22, 2017, and the Section 382 Tax Benefits Preservation Plan on January 8, 2018 (the “ Poison Pill ”), promptly after the Reporting Person filed the original Statement and indicated that the Reporting Person believed that the Issuer was being mismanaged), (iii) that the Issuer’s Chief Executive Officer (“ CEO ”) commutes to Alaska at the cost of the Issuer’s shareholders, has recently sold a significant amount of the Common Stock and receives approximately a $3,000,000 dollar salary, which is far in excess of executive compensation in any comparable public company, evidencing that the CEO has no incentive to maximize shareholder value, (iv) the failure by the Issuer and current management to retain a financial advisor to review strategic alternatives, as the Reporting Person suggested, which would be in the best interests of the Issuer’s shareholders, (v) that Shawn O’Donnell, upon information and belief, the only independent member of the Board, recently resigned, and the Reporting Person believes that Mr. O’Donnell may have resigned due to the Board’s unwillingness to include Mr. O’Donnell in its decision-making processes, in apparent violation of the Board’s duty to consider the input of each member of the Board, and (vi) the superior qualifications of the Reporting Person’s Nominees.

TAR Holdings has attempted to engage, and remains open to engaging, with the Board and management of the Issuer to reach a mutually agreeable resolution that would avoid the need for an election contest at the Annual Meeting. TAR Holdings will also request a waiver of the Poison Pill in order to purchase up to 14.9% of the Issuer’s common stock and plans on voting against ratification of the Poison Pill at the Annual Meeting.
