Exhibit 99.1

Amended and Restated
Non-Employee Director Compensation Policy

1.Introduction

Each member of the Board of Directors (the “Board”) of Snowflake Inc. (“Snowflake”) who is a non-employee director of Snowflake (each such member, a “Non-Employee Director”) will receive the compensation described in this Amended and Restated Non-Employee Director Compensation Policy (“Policy”) for his or her Board service. This Policy may be amended at any time in the sole discretion of the Board or the Compensation Committee of the Board.

2.Equity Compensation

Equity awards will be granted under Snowflake’s 2020 Equity Incentive Plan (the “Plan”).

(a)Initial Appointment Equity Grant. On appointment to the Board, and without any further action of the Board or Compensation Committee of the Board, at the close of business on the day of such appointment, a Non-Employee Director will be automatically granted a Restricted Stock Unit Award for Snowflake’s Class A common stock (the “Class A Common Stock”) having a value of $1,000,000 based on the Fair Market Value (as defined in the Plan) of the underlying Class A Common Stock on the date of grant (the “Initial RSU”). Each Initial RSU will vest over three years, with one-third of the Initial RSU vesting on the first, second, and third anniversary of the date of grant. As used herein, the term “Initial Calendar Year” as applicable to each Non-Employee Director means the calendar year in which such Non-Employee Director’s Initial RSU is granted.

(b)Automatic Equity Grants.Without any further action of the Board or Compensation Committee of the Board, at the close of business on the date of each Annual Meeting of Snowflake’s stockholders (“Annual Meeting”), each person who is then a Non-Employee Director – excluding any Non-Employee Director whose Initial Calendar Year falls in the same calendar year as such Annual Meeting – will automatically receive a Restricted Stock Unit Award for Class A Common Stock having a value of $300,000 based on the average Fair Market Value (as defined in the Plan) of the underlying Class A Common Stock for the 20 trading days prior to and ending on the date of grant (the “Annual RSU”). Each Annual RSU will vest on the earlier of (i) the date of the following year’s Annual Meeting (or the date immediately prior to the next Annual Meeting if the Non-Employee Director’s service as a director ends at such meeting due to the director’s failure to be re-elected or the director not standing for re-election); or (ii) the first anniversary of the date of grant.

(c)Vesting; Change of Control. All vesting is subject to the Non-Employee Director’s “Continuous Service” (as defined in the Plan) on each applicable vesting date, even if such Continuous Service does not relate to service on the Board. Notwithstanding the foregoing vesting schedules, for each Non-Employee Director who remains in Continuous Service with Snowflake until immediately prior to the closing of a “Corporate Transaction” (as defined in the Plan), the shares subject to his or her then-outstanding equity awards will become fully vested immediately prior to the closing of such Corporate Transaction.

(d)Remaining Terms. Each Restricted Stock Unit Award will be granted subject to Snowflake’s standard Restricted Stock Unit Award Agreement, in the form adopted from time to time by the Board or the Compensation Committee of the Board.

3.Annual Cash Compensation

For each calendar year following the Initial Calendar Year, each Non-Employee Director will receive the cash compensation set forth below for service on the Board. The annual cash compensation amounts will be payable in equal quarterly installments, in arrears following the end of each quarter in
