Reddit Inc

Directed Share Program

At our request, the underwriters have reserved up to shares of our Class A common stock, or approximately % of the shares offered in this offering, for sale at the initial public offering price through a directed share program to:

•eligible Reddit users and moderators;

•certain members of our board of directors; and

•friends and family members of certain of our employees and directors.

Users and moderators who created an account on or before January 1, 2024 are potentially eligible for the directed share program. Eligible participants must reside in the United States and be at least 18 years of age. Further, eligible users and moderators must be in good standing on our platform and cannot be a current or former Reddit employee.

We will invite users and moderators to participate in the directed share program in six phased priority tiers. We will assign each eligible participant to a tier based on that participant’s contributions to Reddit. User contributions will be measured in karma (a user’s reputation score that reflects their community contributions). Moderator contributions will be measured by membership and moderator actions on our platform. Tier 1 will include certain users and moderators identified by us who have meaningfully contributed to Reddit community programs. Tier 2 will include users who hold at least 200,000 karma and moderators who have performed at least 5,000 moderator actions. Tier 3 will include users who hold at least 100,000 karma and moderators who have performed at least 2,500 moderator actions. Tier 4 will include users who hold at least 50,000 karma and moderators who have performed at least 1,000 moderator actions. Tier 5 will include users who hold at least 25,000 karma and moderators who have performed at least 500 moderator actions. Tier 6 will include all other eligible users and moderators.

If demand for the directed share program in an earlier tier exceeds capacity, eligible users and moderators will have the option to join a waitlist. An invitation to participate in the directed share program does not guarantee that the participant will receive an allocation of shares. Accordingly, we cannot provide any assurance that any eligible participant will receive an invitation or an allocation in the directed share program.

Shares purchased through the directed share program will not be subject to the terms of the lock-up agreement or market standoff restrictions.

The number of shares of Class A common stock available for sale to the general public will be reduced to the extent that such persons purchase such reserved shares. Any reserved shares not so purchased will be offered by the underwriters to the general public on the same basis as the other shares offered by this prospectus. Other than the underwriting discount described on the front cover of this prospectus, the underwriters will not be entitled to any commission with respect to shares of Class A common stock sold pursuant to the directed share program. We will agree to indemnify the underwriters against certain liabilities and expenses, including liabilities under the Securities Act, in connection with sales of the shares reserved for the directed share program. will administer our directed share program.
