Item 5.02 Departure of Directors or Certain Officers;

Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers

Appointment of Erin Schaefer as Director

On October 1, 2026, the Board of Directors of RTB

Digital, Inc., a Nevada corporation (the “Company”), appointed Erin Schaefer as a director of the Company. Ms. Schaefer will

serve as a director until her successor is duly elected and qualified.

Ms. Schaefer began her executive career with a 14-year

tenure at Google, including Managing Director of Global Operations at Youtube, Global Brand Advertising Strategy, and led Americas video

advertising. Erin built the brand commercialization engine from scratch into a $10B+ global revenue business and led a major turnaround

of YouTube’s Trust & Safety function, earning Google’s Great Manager Award for her leadership. As a transformative leader

in digital innovation, Schaefer scaled multi-billion-dollar commercial engines, leading high-stakes organizational turnarounds, and driving

global operations at the frontier of technology. Most recently, she served as Chief Operating Officer at General Catalyst ($43B+ AUM),

where she directed the operating model and capital allocation.

Previously, Ms. Schaefer was General Manager and P&L

owner at Niantic, overseeing the US Gaming Studio, Global Game Publishing, and the B2B Niantic Spatial Platform, leading Niantic Games

to a multi-billion dollar exit. Ms. Schaefer holds a B.A. in Political Science from Stanford University and an M.B.A. from Harvard Business

School. She has served on public, private company, and non-profit boards including the Hillsborough Schools Foundation where she is currently

the President.

The Company believes Ms. Schaefer’s business,

board, and leadership experience, together with her industry relationships, will provide the Board and the Company with valuable perspective

as the Company develops and operates its enterprise media operating system.

In connection with her appointment, Ms. Schaefer will

enter into the Company’s standard form of Board of Directors Agreement. Under the agreement, Ms. Schaefer will be eligible to receive

an annual equity award with a grant-date fair value of $150,000, to be granted in the form of restricted stock units (“RSUs”).

Because Ms. Schaefer was appointed other than at an annual meeting of shareholders, she will receive a prorated RSU award for the portion

of the 2026 annual service period remaining following the full execution of her Board of Directors Agreement. The number of RSUs will

be determined based on the average closing price of the Company’s common stock over the five consecutive trading days ending on

the trading day immediately preceding the applicable grant date. The annual and prorated awards vest in full on December 31 of the applicable

calendar year, subject to Ms. Schaefer’s continued service through the vesting date. Ms. Schaefer will also be eligible for reimbursement

of reasonable, approved business expenses and may receive such additional cash compensation as may be authorized by the Compensation Committee

from time to time.

There is no arrangement or understanding between Ms.

Schaefer and any other person pursuant to which she was selected to serve as a director. Ms. Schaefer does not have any family relationships

with any of the Company’s executive officers or directors, and does not have any direct or indirect material interest in any transaction

or proposed transaction required to be reported under Item 404(a) of Regulation S-K.
