**Item 1.01. Entry into a Material Definitive Agreement.**

The disclosure set forth under the heading Additional Capped Call Transactions in Item 8.01 of this Current Report on Form 8-K is incorporated by reference into this Item 1.01.

**Item 2.03. Creation of a Direct Financial Obligation under an Off-Balance Sheet Arrangement of a Registrant.**

The disclosure set forth under the heading Option Notes in Item 8.01 of this Current Report on Form 8-K is incorporated by reference into this Item 2.03.

**Item 3.02. Unregistered Sales of Equity Securities.**

The disclosure set forth under the heading Option Notes in Item 8.01 of this Current Report on Form 8-K is incorporated by reference into this Item 3.02. The Option Notes (as defined below in Item 8.01) were issued to the Initial Purchasers (as defined below in Item 8.01) in reliance upon Section 4(a)(2) of the Securities Act of 1933, as amended (the "Securities Act"), in transactions not involving any public offering. The Option Notes were resold by the Initial Purchasers to persons whom the Initial Purchasers reasonably believe are "qualified institutional buyers," as defined in, and in accordance with, Rule 144A under the Securities Act. Any shares of Class A Common Stock of Fastly, Inc. (the "Company") that may be issued upon conversion of the Option Notes will be issued in reliance upon Section 3(a)(9) of the Securities Act as involving an exchange by the Company exclusively with its security holders. A maximum of 15,624,990 shares of the Company's Class A Common Stock may be issued upon conversion of the Notes (as defined below in Item 8.01), based on the initial maximum conversion rate of 86.8055 shares of the Company's Class A Common Stock per $1,000 principal amount of Notes, which is subject to customary anti-dilution adjustment provisions.

**Item 8.01. Other Events.**

***Option Notes***

On December 15, 2025, the Company was notified by the initial purchasers (the "Initial Purchasers") of the 0% Convertible Senior Notes due 2030 (the "Original Notes") issued in the previously announced private offering, which closed on December 9, 2025, of the exercise in full of their option to purchase an additional $20.0 million in aggregate principal amount of 0% Convertible Senior Notes due 2030 (the "Option Notes," and together with the Original Notes, the "Notes"). On December 17, 2025, the Company closed on the issuance of the Option Notes to the Initial Purchasers. The net proceeds from the sale of the Option Notes were approximately $19.4 million after deducting the Initial Purchasers' discounts and commissions. The Company used approximately $2.0 million of the net proceeds from the sale of the Option Notes to pay the cost of the Additional Capped Call Transactions described below.

The Option Notes have the same terms as the Original Notes issued on December 9, 2025 and were issued under the same Indenture as the Original Notes dated as of December 9, 2025, between the Company and U.S. Bank Trust Company, National Association, as trustee, which terms are described in the Company's Current Report on Form 8-K filed on December 9, 2025 (the "Prior 8-K"). The summary of the foregoing transactions is qualified in its entirety by reference to the text of the Indenture, including the Form of Global Note attached as Exhibit A thereto, which was filed as Exhibit 4.1 to the Prior 8-K and is incorporated herein by reference.

***Additional Capped Call Transactions***

On December 15, 2025, in connection with the exercise by the Initial Purchasers of their option to purchase the Option Notes, the Company entered into privately negotiated capped call transactions (collectively, the "Additional Capped Call Transactions") with certain financial institutions. The Additional Capped Call Transactions cover, subject to anti-dilution adjustments, the aggregate number of shares of the Company's Class A Common Stock that initially underlie the Option Notes, and are expected generally to reduce the potential dilution to the Company's Class A Common Stock upon any conversion of the Option Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of converted Option Notes, as the case may be, with such reduction and/or offset subject to a cap, based on the cap price of the Additional Capped Call Transactions. The cap price of the Additional Capped Call Transactions is initially $23.04 per share (subject to adjustment under the terms of the Additional Capped Call Transactions), which represents a premium of 100% over the last reported sale price of the Company's Class A Common Stock on December 4, 2025. The cost of the Additional Capped Call Transactions was approximately $2.0 million.

The above description of the Additional Capped Call Transactions is a summary and is not complete. A copy of the form of confirmation for the Additional Capped Call Transactions is filed as Exhibit 10.1 to the Prior 8-K and is incorporated herein by reference.
