may vary from participant to participant, group to group, and period to period. Transferability Awards generally may not be sold, transferred for value, pledged, assigned, or otherwise alienated or hypothecated by a participant other than by will or the laws of descent and distribution, and each stock option or SAR may be exercisable only by the participant during his or her lifetime. Clawback Awards will be subject to recoupment in accordance with any clawback policy that we adopt, including any clawback policy required under Rule 10D-1 of the Exchange Act. Amendment and Termination Our Board has the right to amend, alter, suspend, or terminate the 2026 Plan at any time, provided certain enumerated material amendments may not be made without stockholder approval. No amendment or alteration to the 2026 Plan or an Award or Award agreement will be made that would materially impair the rights of the Table of Contents

holder, without such holder’s consent; however, no consent will be required if the Administrator determines in its sole discretion and prior to the date of any change in control that such
amendment or alteration either is required or advisable in order for us, the 2026 Plan, or such Award to satisfy any law or regulation or to meet the requirements of or avoid adverse financial accounting consequences under any accounting standard,
or is not reasonably likely to significantly diminish the benefits provided under such Award, or that any such diminishment has been adequately compensated. The 2026 Plan is expected to be adopted by our Board and approved by our stockholders in
connection with this offering and will automatically terminate as to the grant of future awards, unless earlier terminated by our Board, 10 years after such approval by our Board.

2026 Employee Stock Purchase Plan

In connection with this offering, we intend to adopt the 2026 Employee Stock Purchase Plan (the “2026 ESPP”). The
purpose of the 2026 ESPP is to encourage and enable our eligible employees to acquire a proprietary interest in us through the ownership of our Class A common stock. The maximum number of shares that may be purchased under the 2026 ESPP will
not exceed      shares (the “ESPP Share Pool”); however, the ESPP Share Pool will be increased on January 1 of each calendar year beginning in 20     by a number of shares equal to
% of the outstanding shares on the immediately preceding December 31 (or such lesser amount as approved by the 2026 ESPP Administrator (as defined below)). The
2026 ESPP, and the rights of participants to make purchases thereunder, is intended to qualify under the provisions of Sections 421 and 423 of the Code.

The following description of the 2026 ESPP is not intended to be complete and is qualified in its entirety by the complete
text of the 2026 ESPP, a copy of which will be filed as an exhibit to the registration statement of which this prospectus forms a part. Stockholders and potential investors are urged to read the 2026 ESPP in its entirety.

Administration

The 2026
ESPP will be administered by our board of directors or a committee thereof designated by our board of directors to administer the 2026 ESPP, which we refer to herein as the “ESPP Administrator.” All questions of interpretation of the
2026 ESPP are determined by the ESPP Administrator, whose decisions are final and binding upon all participants. The ESPP Administrator may delegate its responsibilities under the 2026 ESPP to one or more other persons.

Eligibility; Participation

Each employee is eligible to participate in the 2026 ESPP. The offering periods and purchase periods will be determined by the
ESPP Administrator. An eligible employee may begin participating in the 2026 ESPP effective at the beginning of an offering period or any purchase periods within an offering period. Once enrolled in the 2026 ESPP, a participant is able to purchase
shares with payroll deductions at the end of the applicable offering period. Once an offering period is over, a participant may be automatically enrolled in the next offering period unless the participant chooses to withdraw from the 2026 ESPP.

Purchase Price

The price
per share at which shares are purchased under the 2026 ESPP is determined by the ESPP Administrator, but in no event will be less than 85% of the fair market value of the Class A common stock on the first or the last day of the offering period,
whichever is lower. A participant may designate payroll deductions to be used to purchase shares equal to at least $     and any maximum as designated by the ESPP Administrator. A participant may only change the percentage of
compensation that is deducted to purchase shares under the 2026 ESPP (other than to withdraw entirely from the 2026 ESPP) effective at the beginning of an offering period. At the end of each offering period, unless the participant has withdrawn from
the 2026 ESPP,

Table of Contents

payroll deductions are applied automatically to purchase shares at the price described above. The number of shares purchased is determined by dividing the payroll deductions by the applicable
purchase price.

Adjustments

In the event of any reorganizations, recapitalizations, stock splits, reverse stock splits, stock dividends, extraordinary
dividends or distributions, or similar events, the ESPP Administrator will appropriately adjust the number and class of shares available under the 2026 ESPP and the applicable purchase price of such shares.

Limitations on Participation

A participant is not permitted to purchase shares under the 2026 ESPP if the participant would own common stock possessing 5%
or more of the total combined voting power or value of equity interests. A participant is also not permitted to purchase shares with a fair market value in excess of $25,000 in any one calendar year (or more than      shares
in any purchase period). A participant does not have the rights of a stockholder until the shares are actually issued to the participant.

Transferability

Rights
to purchase shares under the 2026 ESPP may not be transferred by a participant and may be exercised during a participant’s lifetime only by the participant.

Amendment and Termination

The 2026 ESPP will become effective when it is approved by our board of directors and our stockholders prior to this offering
in accordance with applicable law. Our board of directors may amend, alter, or discontinue the 2026 ESPP in any respect at any time; however, stockholder approval is required for any amendment that would increase the number of shares reserved under
the 2026 ESPP other than pursuant to an adjustment as provided in the 2026 ESPP or materially change the eligibility requirements to participate in the 2026 ESPP.
