◆New services enabled by the collaboration with MMJ
・DOOH targeting
Enables distribution to specific media by delivery surface and time of day to reach high concentrations of a given
target audience.
Going forward, we will also provide solutions linked to a variety of targeting data provided by MMJ.

・Retargeting/Cross-targeting
Using geographic targeting provided by MMJ, planning and delivery can be tailored for smartphones and other typesof screen. The technology also enables the retargeting of target viewers likely to have encountered the same DOOH
advertising on other screens, for simultaneous delivery of advertising messages across a range of media and screens.

・ReportAfter an ad has been served, the number of people estimated to have viewed the DOOH ads (the number ofimpressions) is calculated and provided as a report. This clarifies the criteria for ad value and shows actualimpressions delivered, providing useful data for evaluating a campaign or developing a new plan.

This partnership will enable the provision of DOOH advertising with flexible, performance-based transactions similar
to those possible in online programmatic advertising. We will announce further updates in due course.
