Pulse Biosciences, Inc. (NASDAQ:PLSE), a company leveraging its novel and proprietary Nanosecond Pulsed Field Ablation™ (nano-PFA or nsPFA™) technology, today announced that it intends to deliver an irrevocable notice of redemption, on or about June 10, 2026, to redeem the remaining common stock warrants issued by the Company as part of its July 3, 2024 rights offering. These outstanding common stock warrants (the "200% Warrants"), which were issued in the Company's 2024 rights offering (the "Rights Offering"), pursuant to the Company's Registration Statement on Form S-3, as amended (File No. 333-278494), may be exercised by the holders thereof until 5:00 p.m., Eastern time, on July 13, 2026, at the exercise price of $11.00 per share of Company common stock, $0.001 par value per share. Any 200% Warrants not exercised before 5:00 p.m., Eastern time, on July 13, 2026 (the "Redemption Date"), will be redeemed by the Company for $0.01 per 200% Warrant share (the "Redemption Price").

Under the terms of the 200% Warrants, the Company has the right to redeem the 200% Warrants (CUSIP # 74587B143) if the volume weighted average price (as defined therein, "VWAP") exceeds $22.00 per share for twenty (20) consecutive trading days at least three months after the date that the 200% Warrants were issued. This requirement was met for each of the twenty consecutive trading days preceding June 10, 2026. Over this period, the Company had an average VWAP of $25.17.

Any 200% Warrants that remain unexercised at 5:00 p.m., Eastern time, on the Redemption Date, will be void and no longer exercisable, and the holders of those 200% Warrants will be entitled to receive only the Redemption Price of $0.01 per 200% Warrant share. The first tranche of common stock warrants issued in the Rights Offering (the "150% Warrants") were redeemed by the Company in February 2025, and none of them are outstanding at this time.

The Company received aggregate gross proceeds of $60 million from its Rights Offering, which was completed in July 2024, and the Company has received an additional $63.7 million of gross proceeds from the redemption of the 150% Warrants and 200% Warrants thus far, and will receive an additional $2.1 million of gross proceeds if the remainder of the 200% Warrants are exercised prior to the Redemption Date.

None of the Company, its board of directors or employees has made or is making any representation or recommendation to any holder of any Warrants as to whether to exercise or refrain from exercising any Warrants.

A registration statement, as amended, relating to the Rights Offering was previously filed with the Securities and Exchange Commission (the "SEC") and declared effective on May 31, 2024. A prospectus relating to the offering was filed with the SEC on and supplemented on June 4, 2024 and is available on the SEC's website.

The Company will post a copy of the notice of redemption being sent to the holders of the 200% Warrants on its investor relations website at investors.pulsebiosciences.com.
