Pulse Biosciences, Inc. Announces the Closing of its Rights Offering

Pulse Biosciences, Inc. (Nasdaq: PLSE) (the “Company” or “Pulse Biosciences”), a company leveraging its novel and proprietary CellFX® Nanosecond Pulsed Field Ablation™ (nsPFA™) technology, announced today the closing of its rights offering and the final results thereof.

The Company received basic subscriptions and over-subscriptions in excess of $83 million, equal to approximately 138% of the $60 million gross proceeds limit in the rights offering, and subscriptions from over 800 accounts, including those of the Company’s Executive Chairman, Robert Duggan. Available Units were allocated proportionately among those rights holders who exercised their over-subscription right based on the number of Units each rights holder subscribed for under its basic subscription rights, in accordance with the procedures described in the prospectus, as amended to date, relating to the rights offering. The remaining oversubscription amounts will be returned by Broadridge Corporate Issuer Solutions, LLC (the “Subscription Agent”) to the investors.

The rights offering resulted in the sale of six million units (the “Units”), at a price of $10.00 per Unit. Each Unit consisted of one share of the Company’s common stock, par value $0.001 per share, and two warrants, each being a warrant to purchase one-half of one share of common stock. The common stock and warrants comprising the Units separated upon the closing of the rights offering and were issued individually. A total of 5,999,999 shares of common stock and warrants to acquire up to an additional approximately six million shares of common stock were issued in the offering. The Company received aggregate gross proceeds from the rights offering of $60 million. If exercised, additional gross proceeds of up to $66 million may be received through the exercise of warrants issued in the rights offering. Each warrant will be exercisable for $11.00 per whole share, which equals 110% of the subscription price for the Units. Warrants are exercisable immediately and will expire on the fifth anniversary of the closing of the rights offering. Half of the warrants issued in the rights offering are redeemable by the Company if the Company’s stock trading price exceeds $16.50 for twenty consecutive trading days and the other half of the warrants issued in the rights offering are redeemable by the Company if its stock trading price exceeds $22.00 for twenty consecutive trading days.

Investors who participated in the rights offering should expect to see the shares and warrants issued to them in book-entry, or uncertificated, form. Shares, warrants and any excess subscription payments are expected to be distributed by the Subscription Agent on or about July 5, 2024.

After giving effect to the issuance of 5,999,999 shares of common stock in the rights offering (but excluding up to approximately six million shares of common stock underlying the warrants issued in the rights offering), the Company has 61,228,332 shares of common stock issued and outstanding.

The Company plans to use proceeds from the offering principally to support further product and clinical development, future regulatory submissions and commercial readiness of its three leading CellFX nsPFA products, Percutaneous Electrode, Cardiac Clamp, and 360° Cardiac Catheter. Each device is designed to deliver significant clinical advantages compared to the current standards of care and have a potential profound positive impact on healthcare for both patients, providers and other stakeholders.

The rights offering was made pursuant to the Company’s registration statement on Form S-3, as modified by the post-effective amendment filed with the Securities and Exchange Commission (“SEC”) on May 28, 2024, which was deemed effective by the SEC on May 31, 2024, including the prospectus contained therein, as further modified by the prospectus filed pursuant to Rule 424(b)(2) of the Securities Act of 1933, which contains the detailed terms of the rights offering and was filed with the SEC on June 4, 2024.
