LIVE BOARD announces 26 screens at Seibu Railway Ikebukuro Station
to serve digital out of home (DOOH) ads based on impressions (VAC) fromJune 24, 2024

LIVE BOARD,INC. will connect and link 26 screens of the Seibu Railway Ikebukuro Station Smile Station Vision (1st floor/B1 area) installed on the 1st floor of Ikebukuro Station on the Seibu Railway Ikebukuro Line to the LIVE BOARD Marketplace*1
from June 24, 2024.
In addition to the conventional sales method of specifying the delivery period and frequency, NTT DOCOMO's location data
and analysis technology will enable this digital media to develop a model to estimate the number of passengers and viewers
in stations, and to sell impressions (VAC)*2 based on the number of people estimated to have actually seen the ad.

Ikebukuro Station is served by many train lines and is one of the world's top-ranked stations, with an average of more than
2 million passengers per day. The station is surrounded by department stores, electronics retail stores, and commercial
facilities that are used by people of all ages. Seibu Railway Ikebukuro Station Smile Station Vision (1st floor/B-1 area) is
located on the route leading from the ticket gates to the department stores and other lines, making it a location that appeals
not only to users along the Seibu Line but also to those on other lines.

LIVE BOARD will continue to create new value for the expansion of the DOOH market by implementing effective and efficientmanagement of transportation advertising, and will further promote the realization of advertising delivery adapted to diverse
lifestyles.

＊1 This refers to the entire DOOH advertising space (inventory) handled by LIVE BOARD, including its own and other companies'.
＊2 LIVE BOARD uses impressions that take into account the visibility rate based on visibility surveys (VAC = Visibility Adjusted Contact / total number ofpeople who saw the ad), as recommended in the OOH Global Measurement Guidelines. Of the number of people in the viewing area of a medium (OTS =Opportunity to See), the number of people who may come into contact with an OOH ad (OTC = Opportunity to Contact / takes into account the direction ofmovement within the viewing area and the presence of obstacles) is defined. The number of people who are likely to actually see the advertisement (VAC) isestimated by adding the visibility rate for each media to this number.
