SCHEDULE 13D

This statement on Schedule 13D (this “Statement”) relates to the Class A common stock, par value $0.01 per share (the “Class A Common Stock”), of MediaAlpha, Inc., a Delaware corporation (“MediaAlpha”). MediaAlpha’s principal executive offices are located at 700 South Flower Street, Suite 640, Los Angeles, CA, 90017.

(a)          This Statement is filed on behalf of the following persons (collectively, the “Reporting Persons”): Eugene Nonko and O.N.E. Holdings, LLC, a Washington limited liability company (“O.N.E. Holdings”). Mr. Nonko is the managing member of O.N.E. Holdings, which is owned by trusts established for the benefit of Mr. Nonko and his immediate family members.

(b)          The business address of Mr. Nonko is 700 South Flower Street, Suite 640, Los Angeles, CA, 90017. The business address of O.N.E. Holdings is 7607 224th Ave NE, Redmond, WA, 98053.

(c)          The present principal occupation of Mr. Nonko is serving as Chief Technology Officer and Co-Founder of MediaAlpha. The principal business of MediaAlpha is providing digital online customer acquisition solutions to the insurance industry. The principal business of O.N.E. Holdings is acquiring and holding securities for investment purposes.

(d)          During the last five years, neither of the Reporting Persons has been convicted in a criminal proceeding (excluding traffic violations and similar misdemeanors).

(e)          During the last five years, neither of the Reporting Persons has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction nor, as a result of such proceeding, was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

(f)          Eugene Nonko is a citizen of the United States of America.

In addition, on October 30, 2020, Mr. Nonko received a grant of 1,837,765 restricted stock units under MediaAlpha's Omnibus Incentive Plan. The restricted stock units will vest quarterly over the first three years following the date of grant, subject to continued employment with MediaAlpha through each vesting date. Each restricted stock unit represents a contingent right to receive one share of Class A Common Stock.

O.N.E. Holdings is a party to an exchange agreement (the “Exchange Agreement”), dated October 27, 2020, pursuant to which (and subject to the terms thereof) holders of Class B-1 units of QL Holdings LLC (“Class B-1 units”), from time to time, may exchange one Class B-1 unit, together with the corresponding share of Class B Common Stock of MediaAlpha (“Class B Common Stock”), for one share of Class A Common Stock (or, at the election of MediaAlpha, cash of an equivalent value). As of June 16, 2021, O.N.E. Holdings held 3,970,051 Class B-1 units and 3,970,051 shares of Class B Common Stock.  As of result of the Lock-Up Expiration, pursuant to the Exchange Agreement, O.N.E. Holdings has the right to acquire 3,970,051 shares of Class A Common Stock by exchanging such Class B-1 units and Class B Common Stock for Class A Common Stock on a one-for-one basis.

Mr. Nonko has entered into a trading plan (the “Trading Plan”) pursuant to rule 10b5-1 under the Act. Pursuant to the Trading Plan, a broker dealer will make periodic sales of shares of Class A Common Stock on behalf of Mr. Nonko to raise net proceeds approximately equivalent to the estimated tax liability arising from the quarterly vesting of restricted stock units issued to Mr. Nonko by MediaAlpha, subject to the terms of the Trading Plan.

The foregoing description of the Trading Plan is qualified in its entirety by the full text of the Trading Plan, the form of which is included as an exhibit to this Schedule 13D and is incorporated by reference.

No Reporting Person currently has any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) – (j) of Item 4 of Schedule 13D except as set forth herein or such as would occur upon or in connection with the completion of, or following, any of the actions discussed herein.

(a)          The Reporting Persons may be deemed to beneficially own in the aggregate 4,362,837 shares of Class A Common Stock, representing approximately 10.1% of MediaAlpha’s outstanding shares of Class A Common Stock. The percentages of beneficial ownership in this Statement are based on 38,623,954 shares of Class A Common Stock reported to be outstanding as of March 31, 2021, as disclosed in MediaAlpha’s Quarterly Report on Form 10-Q for the period ended March 31, 2021 filed with the SEC on May 14, 2021.

(b)          Eugene Nonko beneficially owns and has sole voting and dispositive power over 4,362,837 shares of Class A Common Stock, comprised of (i) 239,639 shares of Class A Common Stock directly owned by Mr. Nonko, (ii) 3,970,051 shares of Class B Common Stock owned by O.N.E. Holdings (which, along with corresponding Class B-1 units), may from time to time be exchanged on a one-for-one basis for Class A Common Stock) and (iii) 153,147 shares of Class A Common Stock issuable to Mr. Nonko upon settlement of outstanding restricted stock units that vest within 60 days of the date of this Statement.

By virtue of his position as Manager of O.N.E. Holdings, Mr. Nonko may be deemed to have sole power to vote and dispose of the shares of Class A Common Stock reported owned by O.N.E. Holdings.

(c)          On April 30, 2021, Mr. Nonko acquired 153,146 shares of Class A Common Stock upon the vesting of restricted stock units.  On May 24, 2021, Mr. Nonko sold 825 shares of Class A Common Stock at a weighted average price per share of $40.0221.
