had been similar estimated growth rates for the previous days in August.

The Company has not completed its normal review and validation of its preliminary internal data, and this

information should not be read as indicative of the Company's expected results for Q3 2026 or any future

period.

The Company's most recent guidance is set forth in its Q2 2026 shareholder letter dated August 5, 2026.

time.

purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or

otherwise subject to the liabilities of that Section, nor shall it be deemed to be incorporated by reference

into any filing of the Company under the Securities Act of 1933, as amended, or the Exchange Act,

except as expressly set forth by specific reference in such filing.
