Item 8.01     Other Events

On July 31, 2026, the board of directors (the “Board”) of BlackLine, Inc. (the “Company”) approved an increase to the Company’s stock buyback program (the “Stock Buyback Program”) of an additional $100 million, for a total overall authorization to repurchase up to $600 million of the Company’s common stock. As of August 3, 2026, the Company has repurchased 7.2 million shares, or $327.8 million, under the Stock Buyback Program.

Repurchases may be made from time to time through open market repurchases or through privately negotiated transactions subject to market conditions, applicable legal requirements and other relevant factors. Open market repurchases may be structured to occur in accordance with the requirements of Rule 10b-18 of the Securities Exchange Act of 1934, as amended. The Company may also, from time to time, enter into Rule 10b5-1 plans to facilitate repurchases of its shares under this authorization. The repurchase program does not obligate the Company to acquire any particular amount of its Class A common stock, and it may be suspended at any time at the Company’s discretion. The timing and actual number of shares repurchased may depend on a variety of factors, including price, general business and market conditions, and alternative investment opportunities. The Stock Buyback Program may be suspended, terminated, amended or modified by the Board at any time without prior notice, at the Board’s discretion.
