Warrant redemption may add up to $2.1M for Pulse Biosciences (PLSE)

Rhea-AI Filing Summary

Pulse Biosciences plans to redeem its remaining common stock “200% Warrants” issued in the July 3, 2024 rights offering. Holders may exercise these warrants at $11.00 per share until 5:00 p.m. Eastern on July 13, 2026, after which any unexercised warrants will be redeemed for $0.01 per warrant share and then become void.

The company’s right to redeem was triggered because its common stock’s volume weighted average price exceeded $22.00 for 20 consecutive trading days, with an average VWAP of $25.17 over that period. Pulse Biosciences reports it has already raised $60 million in gross proceeds from the rights offering and a further $63.7 million from warrant exercises, and it may receive an additional $2.1 million if all remaining 200% Warrants are exercised before the redemption deadline.

Key Terms

5 terms

200% Warrants financial

"These outstanding common stock warrants (the “200% Warrants”), which were issued in the Company’s 2024 rights offering"

Rights Offering financial

"issued on July 3, 2024 (“Warrants”) in connection with the Company’s rights offering"

A rights offering is a way for a company to raise additional money by giving existing shareholders the opportunity to buy more shares at a discounted price before they are offered to the public. It’s similar to a special sale where current owners get the first chance to buy extra items at a lower cost, allowing them to increase their investment if they choose. This process matters to investors because it can affect the value of their holdings and their ability to buy new shares at favorable terms.

volume weighted average price financial

"if the volume weighted average price of the Company’s common stock equals or exceeds 200% of the exercise price"

The volume weighted average price (VWAP) is a way to measure the average price of a security, such as a stock, over a specific period, taking into account how many units were traded at each price. It’s similar to calculating the average cost of items bought when some are more frequently purchased than others. Investors use VWAP to assess whether a security is being bought or sold at a fair price during trading.

Nanosecond Pulsed Field Ablation technical

"leveraging its novel and proprietary Nanosecond Pulsed Field Ablation™ (nano-PFA or nsPFA™) technology"

Nanosecond pulsed field ablation is a medical technique that uses extremely short, high‑voltage electrical pulses—each lasting billionths of a second—to selectively disable small areas of tissue, most often to treat irregular heart rhythms. Like a precise, ultra‑brief electric zap that spares surrounding structures, it matters to investors because it can shorten procedure time, reduce complications and recovery, and therefore reshape demand, pricing and adoption for cardiac ablation devices and related services.

forward-looking statements regulatory

"All statements in this press release that are not historical are forward-looking statements"

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

PULSE BIOSCIENCES, INC. ANNOUNCES PLANNED REDEMPTION OF WARRANTS

HAYWARD, Calif.--(BUSINESS WIRE)—June 10, 2026—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.

Questions concerning redemption and exercise of the 200% Warrants can be directed to Broadridge Corporate Issuer Solutions, LLC, Attn: BCIS Re-Organization Dept., P.O. Box 1317, Brentwood, NY 11717-0718, telephone number 888-789-8409 or to shareholder@broadridge.com.
