ALPHA TAU MEDICAL LTD.
This prospectus relates to the issuance from time to time by Alpha Tau Medical Ltd., a company organized under the laws of the State of Israel (“we,” “our,” the “Company” or “Alpha Tau”) of up to 15,747,677 ordinary shares, no par value per share (the “ordinary shares”), including (a) 13,605,677 ordinary shares issuable upon the exercise of warrants of the Company that were issued in exchange for the public warrants of Healthcare Capital Corp., a Delaware corporation (“HCCC”) (the “public warrants”), at the closing of the Business Combination (as defined herein), following exercise of a total of 144,323 public warrants as of August 31, 2022, and (b) 2,142,000 ordinary shares issuable upon the exercise of the warrants that were issued in exchange for the private warrants of HCCC (the “private warrants” and, together with the public warrants, the “warrants”) at the closing of the Business Combination. The public warrants of HCCC were originally issued in the initial public offering of units of HCCC at a price of $10 per unit, with each unit consisting of one share of Class A common stock of HCCC (the “HCCC Class A Shares”) and one half of one warrant of HCCC. The private warrants of HCCC were originally issued in a private placement at a price of $1.00 per warrant in connection with the initial public offering of HCCC.
This prospectus also relates to the resale, from time to time, by the selling securityholders named herein (the “Selling Securityholders”), or their pledgees, donees, transferees, or other successors in interest, of up to 9,200,947 ordinary shares (the “PIPE Shares”) issued to certain of the Selling Securityholders in a private placement that closed in connection with the Business Combination, at an issuance price of $10 per ordinary share, as described below.
Each warrant entitles the holder to purchase one ordinary share at an exercise price of $11.50 per share and will expire on March 7, 2027, at 5:00 p.m., New York City time, or earlier upon redemption of the public warrants or liquidation of the Company. We may redeem the outstanding public warrants at a price of $0.01 per warrant if the last reported sales price of our ordinary shares equals or exceeds $18.00 per ordinary share (subject to adjustment in accordance with the terms of the public warrants) for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which we send the notice of redemption to the warrant holders, as described herein. The private warrants have terms and provisions that are identical to those of the public warrants, except as described herein.
We are registering the PIPE Shares for resale by the Selling Securityholders named in this prospectus, or their transferees, pledgees, donees or assignees or other successors-in-interest that receive any of the shares as a gift, distribution, or other non-sale related transfer.
We are registering the offer and sale of the PIPE Shares to satisfy certain registration rights we have granted. The Selling Securityholders may offer and sell the PIPE Shares from time to time at fixed prices, at market prices or at negotiated prices, and may engage a broker, dealer or underwriter to sell the securities. In connection with any sales of the PIPE Shares offered hereunder, the Selling Securityholders, any underwriters, agents, brokers or dealers participating in such sales may be deemed to be “underwriters” within the meaning of the Securities Act. For additional information on the possible methods of sale that may be used by the Selling Securityholders, you should refer to the section entitled “Plan of Distribution” elsewhere in this prospectus. We do not know when or in what amounts the Selling Securityholders may offer the securities for sale. The Selling Securityholders may sell any, all or none of the PIPE Shares offered by this prospectus.
All of the PIPE Shares offered by the Selling Securityholders pursuant to this prospectus will be sold by the Selling Securityholders for their respective accounts. We will not receive any proceeds from the sale of any PIPE Shares by the Selling Securityholders. We will receive up to an aggregate of $181,098,286 from the exercise of the warrants, assuming the exercise in full of all the warrants for cash and not including the approximately $1.7 million we have previously received upon exercise of 144,323 of the public warrants prior to the date of this prospectus). If the warrants are exercised pursuant to a cashless exercise feature, we will not receive any cash from these exercises. We expect to use the net proceeds from the exercise of the warrants, if any, for general corporate purposes. We believe the likelihood that warrant holders will exercise their warrants, and therefore the amount of cash proceeds that we would receive, is dependent upon the market price of our ordinary shares. If the market price for our ordinary shares is less than $11.50 per share, we believe warrant holders will be unlikely to exercise their Warrants.
We will pay certain expenses associated with the registration of the securities covered by this prospectus, as described in the section entitled “Plan of Distribution.”
Our ordinary shares and warrants are listed on the Nasdaq Stock Market LLC under the trading symbols “DRTS” and “DRTSW,” respectively. On September 2, 2022, the closing prices for our ordinary shares and warrants on the Nasdaq Stock Market LLC were $6.68 per ordinary share and $0.47 per warrant.
Prior to the special meeting of HCCC in connection with the Business Combination, holders of 26,345,782 HCCC Class A Shares exercised their right to redeem those shares for cash at a price of $10.00 per share, for an aggregate of $263,457,820, which represented approximately 95.8% of the total HCCC Class A Shares then outstanding. The ordinary shares being offered for resale in this prospectus represents a substantial percentage of our total outstanding ordinary shares as of the date of this prospectus. Additionally, if all the warrants are exercised, the holders of such warrants would own an additional 15,747,677 ordinary shares, which would then represent 18.6% of our total ordinary shares outstanding following such exercise. The sale of all the securities being offered in this prospectus could result in a significant decline in the public trading price of our ordinary shares. Despite such a decline in the public trading price, the Selling Securityholders and warrant holders may still experience a positive rate of return on the securities they purchased due to the differences in the purchase prices of which they purchased the ordinary shares and the warrants described above.
