#### Insider Trading Compliance Policy and Practices
We have adoptedinsider trading policies and procedures that govern the purchase, sale, and other dispositions of our securities by ourselves, directors, officers, or employees that are reasonably designed to promote compliance with insider trading laws, rules and regulations, and any applicable listing standards (our “Insider Trading Compliance Policy”). Our Insider Trading Compliance Policy prohibits all our employees, including our named executive officers, and the members of our Board from engaging in derivative securities transactions, including hedging, with respect to our common stock and from pledging our securities as collateral or holding our securities in a margin account. A copy of our Insider Trading Compliance Policy was filed as Exhibit 19 to our 2024 Form 10-K. We also maintain guidelines for entering into a pre-arranged trading plan pursuant to Rule 10b5-1 of the Exchange Act. It is BlackLine’s practice to comply with all applicable laws when engaging in transactions in BlackLine’s securities.

#### Corporate Responsibility and Sustainability
BlackLine recognizes the importance of a thoughtful approach to corporate citizenship, and this is reflected in our Board's oversight of our ESG programs. Our Nominating and Corporate Governance Committee oversees our programs relating to corporate responsibility and sustainability, including environmental, social, and corporate governance matters, and our Compensation Committee oversees our efforts to develop our workforce, and management's efforts to foster a corporate culture in alignment with the Company's values and strategy.

In 2025, we published an environmental sustainability report on our website at http://www.blackline.com/legal/blackline-corporate-responsibility/ that describes our environmental sustainability initiatives and carbon emissions, and aligns to globally-recognized ESG reporting frameworks and standards. Although these disclosures are not incorporated by reference into this proxy statement, we believe our environmental sustainability report offers valuable insights into the ways our business aligns favorably with important goals in these areas, and we intend to periodically update that report to reflect any significant developments in our environmental sustainability initiatives and metrics.
