Fastly, Inc.

Stock Ownership Guidelines

Our Board adopted mandatory stock ownership guidelines for our CEO, other executive officers and non-employee directors (together, “Guideline Participants”). These guidelines are intended to align the interests of our Guideline Participants with those of our stockholders by requiring them to acquire and maintain a meaningful equity stake in the Company.

In February 2024, our Compensation Committee introduced more robust stock ownership guidelines for our Named Executive Officers, requiring the CEO to hold 6x his annual base salary (up from 3x), and other executive officers to hold 3x their annual base salary (up from 1x).

These guidelines are based on the individual holding shares of our common stock with a value equal to a multiple of his or her annual base salary or annual cash retainer, as follows:

For purposes of this calculation, stock ownership includes (i) shares of common stock owned directly, including restricted shares and shares deliverable upon settlement of restricted or unrestricted stock units, including restricted or unrestricted stock units that have not yet vested and are subject only to time-based vesting, and excluding restricted shares or restricted stock units that remain subject to achievement of performance goals, such as performance share units and (ii) shares of our common stock owned indirectly if the Guideline Participant has an economic interest in the shares (which includes shares beneficially owned for purposes of the Exchange Act). Stock ownership does not include shares underlying stock options or otherwise subject to a right to acquire, except to the extent expressly provided in the guidelines.

Each Guideline Participant must satisfy the required level of stock ownership under the guidelines by the fifth anniversary of the date such Guideline Participant became subject to the guidelines.

Anti-hedging Policy

Our Insider Trading Policy, as further described below, includes an anti-hedging provision that prohibits all of our employees, including our Named Executive Officers, and our non-employee directors from hedging the risk associated with ownership of shares of Fastly common stock and other Fastly securities, including (i) purchasing financial instruments (including prepaid variable forward contracts, equity swaps,

collars and exchange funds) or otherwise engaging in transactions that are designed to or have the effect of hedging or offsetting any decrease in the market value of Company equity securities, (ii) holding Company securities in a margin account, and (iii) engaging in derivative securities transactions or any form of short-term speculative trading in Company securities.

Anti-pledging Policy

Our Insider Trading Policy also prohibits all employees, including our Named Executive Officers and directors from pledging Company securities as collateral for a loan unless the employee or director clearly demonstrates financial capacity to repay the loan without resort to the pledged securities, and the Chief Legal Officer and Chief Financial Officer collectively grant an exception based on guidelines approved by the Compensation Committee. Any pledge of Company securities by a director or executive officer must be approved in advance by the Compensation Committee.

In November 2019, following approval by our Compensation Committee, Mr. Bergman, our then-Chief Executive Officer, pledged 2,269,584 shares of our common stock as collateral to secure certain personal indebtedness, which later increased by 567,396 shares (totaling up to 25% of his outstanding shares) following volatility of our common

stock (the “2019 Pledge”). In granting the approval, the Compensation Committee considered several factors including, among others, stock volatility, loan to value ratio and his ability to repay the loan (the “Approval Factors”). After the termination of the 2019 Pledge, in February 2024, our Compensation Committee considered the Approval Factors and approved Mr. Bergman’s ability to enter into a new personal line of credit and pledge up to 25% of his outstanding shares of common stock. In March 2024, Mr. Bergman pledged 1,350,000 shares of our common stock as collateral to secure personal indebtedness. None of Mr. Bergman’s shares are pledged as collateral for margin accounts. The pledged shares are not used to shift or hedge any economic risk in owning our common stock. No other executive officer or director holds shares of our common stock that have been pledged to secure any personal or other indebtedness or for any other purpose.
