    <ffd:OfferingNote contextRef="offrl_1" id="ixv-214">Pursuant to Rule 416(a) under the Securities Act of 1933, as amended (the "Securities Act"), this Registration Statement shall also cover any additional shares of Common Stock that become issuable under the Orchestra BioMed Holdings, Inc. 2026 Employee Stock Purchase Plan (the "ESPP") by reason of any stock dividend, stock split, recapitalization or other similar transaction effected without receipt of consideration that increases the number of the Registrant's outstanding shares of Common Stock.

The "Amount Registered" represents 750,000 shares of Common Stock reserved for issuance under the ESPP.

The "Proposed Maximum Offering Price" is estimated solely for the purpose of calculating the amount of the registration fee pursuant to Rule 457(c) and Rule 457(h) of the Securities Act, and is calculated based on $3.9225 per share, the average of the high and low prices of the Common Stock, as reported on the Nasdaq Global Market on June 17, 2026, which is a date within five business days prior to the date of filing the Registration Statement.
