Exhibit 99.1

BCLS Acquisition Corp. will redeem its Public Shares and will not consummate an initial business combination

Boston, Massachusetts, October 21, 2022 – BCLS Acquisition Corp. (the “Company”) (Nasdaq: BLSA), a special purpose acquisition company, today announced that as of the close of business on October 26, 2022, the Company’s publicly held Class A ordinary shares, par value $0.0001 (the “Public Shares”), will be deemed cancelled and will represent only the right to receive their pro-rata share in the Company’s trust account (“Trust Account”), because the Company will not consummate an initial business combination within the time period required by its Amended and Restated Memorandum and Articles of Association (the “Articles”).

As stated in the Company’s Articles and in the Company’s registration statement on Form S-1 (Registration No. 333-249284), initially filed with the United States Securities and Exchange Commission (the “Commission”) on October 2, 2020, relating to the Company’s initial public offering, if the Company is unable to complete an initial business combination within 24 months of the initial public offering, the Company will: (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its income taxes, if any (less up to $100,000 of interest to pay dissolution expenses), divided by the number of the then-outstanding Public Shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any); and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Company’s board of directors, liquidate and dissolve, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.

The per-share redemption price for the Public Shares will be approximately $10.03 (the “Redemption Amount”). The balance of the Trust Account as of September 30, 2022 was $144,329,573, which includes $579,573 in interest and dividend income (excess of cash over $143,750,000, the funds deposited into the Trust Account). In accordance with the terms of the related trust agreement, the Company expects to retain $100,000 of the interest and dividend income from the Trust Account to pay dissolution expenses.

As of the close of business on October 26, 2022, the Public Shares will be deemed cancelled and will represent only the right to receive the Redemption Amount within ten business days. The Company anticipates that the Public Shares will cease trading on The Nasdaq Capital Market (“Nasdaq”) as of the close of business on October 26, 2022.

The Redemption Amount will be payable to the holders of the Public Shares upon delivery of their shares to the Company’s transfer agent, Continental Stock Transfer & Trust Company. Beneficial owners of Public Shares held in “street name,” however, will not need to take any action in order to receive the Redemption Amount.

The Company’s sponsor has waived its redemption rights with respect to the outstanding founder shares and private placement shares. After October 26, 2022, the Company shall cease all operations except for those required to wind up the Company’s business.

The Company expects that Nasdaq will file a Form 25 with the Commission in order to delist the Company’s securities. The Company thereafter expects to file a Form 15 with the Commission to terminate the registration of the Company’s securities under the Securities Exchange Act of 1934, as amended.
