### Code of Business Conduct and Ethics
Our Board has adopted a written code of business conduct and ethics that applies to all of our employees, officers, and directors, including our Co-CEOs, Chief Financial Officer, and other executive and senior financial officers. The full text of our code of business conduct and ethics is available on the corporate governance section of our website, which is located at http://investors.blackline.com. We intend to disclose any amendments to our code of business conduct and ethics, or waivers of its requirements, on our website or in filings under the Exchange Act. We are committed to maintaining high standards of financial integrity, open communication, and a workplace environment where employees can raise concerns free of harassment, discrimination or retaliation. We maintain a formal whistleblower policy which describes the means by which employees, directors, and officers can report suspected violations of our code of business conduct and ethics. Reports of suspected violations may be made directly to human resources or the legal department, or through our reporting hotline, which allows anonymous reporting where permitted by law. Retaliation is strictly prohibited under both our code of business conduct and ethics and our whistleblower policy.
