This Form 4 filing is a routine disclosure of insider trading activity. It does not provide information directly related to broader industry trends or competitive positioning for Datadog, a leader in monitoring and analytics for cloud applications.

Stakeholder Impact

• Shareholders: May observe a slight decrease in insider ownership, but the pre-planned and tax-related nature of the sales mitigates concerns about management's confidence.
• Employees: No direct impact mentioned, but the vesting of RSUs/PBRSUs indicates ongoing equity compensation practices.
