No. 7 (&ldquo;Amendment No. 7&rdquo;) amends and restates the Statement on Schedule 13D initially filed with the U.S. Securities and

No. 1 filed on September 9, 2022 (&ldquo;Amendment No. 1&rdquo;), Amendment No. 2 filed on March 10, 2023 (&ldquo;Amendment No. 2&rdquo;),
Amendment No. 3 filed on June 12, 2023 (&ldquo;Amendment No. 3&rdquo;), Amendment No. 4 filed on September 12, 2023 (&ldquo;Amendment
No. 4&rdquo;), Amendment No. 5 filed on December 19, 2023 (&ldquo;Amendment No. 5&rdquo;) and Amendment No. 6 filed on June 17, 2024
(&ldquo;Amendment No. 6&rdquo;). This Amendment No. 7 relates to the beneficial ownership of Class A Common Stock, par value $0.0001
per share (&ldquo;Class A Common Stock&rdquo;), of Samsara Inc., a corporation organized under the laws of the state of Delaware (&ldquo;Issuer&rdquo;).
This Amendment No. 7 is being filed to update the aggregate percentage of the Issuer&rsquo;s Class A Common Stock owned by the Reporting
Persons (as defined below) due to dilution caused by the Issuer&rsquo;s issuance of additional shares of its Class A Common Stock from
time to time since the date of the filing of Amendment No. 6. Based on the number of outstanding shares of the Issuer&rsquo;s Class A
Common Stock as reported in its Form 10-Q filed on September 10, 2024 with the SEC (File No. 001-41140) (the &ldquo;10-Q&rdquo;), such
dilution resulted in a decrease of over one percent (1%) in the aggregate percentage ownership reported by certain of the Reporting Persons
in Amendment No. 6. This Amendment No. 7 also reflects the subsequent conversion of Class B Common Stock, and the disposition of the
shares of Class A Common Stock received upon such conversion, by certain of the Reporting Persons. Shares reported in this Amendment
No. 7 are as of September 12, 2024 unless otherwise specified herein.</FONT></P>
