Alpha Tau & Healthcare Capital Corp. to Combine and Create A $1-Billion Publicly Traded Company

Alpha Tau and Healthcare Capital Corp. to Combine and Create A Publicly Traded Company Focused on Transforming the Treatment of Solid Tumors Through the Precision Delivery of Alpha Radiation

- Alpha Tau's proprietary Alpha DaRT™ is designed to deliver uniquely potent alpha radiation to destroy solid tumors with localized precision, sparing surrounding healthy tissue, thereby maintaining cancer patients' quality of life. Alpha DaRT™ has recently received FDA's Breakthrough Device Designation for the indication of Squamous Cell Carcinoma of the skin and oral cavity without curative standard of care, and preclinical studies support evaluation across various cancer indications (skin, pancreas, breast and GBM, among others).

- The transaction represents an implied pro forma equity value of approximately $1 billion and is expected to provide up to $367 million in gross proceeds, including up to $275 million of cash held in the trust account of Healthcare Capital Corp. (Nasdaq: HCCC) and a $92 million PIPE.

- The $92 million fully-committed PIPE is anchored by a combination of Healthcare-focused financial and strategic investors including Yozma Investment Co. (part of Yozma Group Korea), Grand Decade Developments (an affiliate of China Grand Pharmaceutical and Healthcare Holdings), as well as other leading technology investors including OurCrowd, Regah Ventures and the co-founders of Apax Partners, Alan Patricof and Sir Ronald Cohen. Medison Group, an early supporter of Alpha Tau and global pharma company that provides access to highly innovative therapies to patients in international markets, is also an investor in the PIPE.

- After giving effect to the transaction (and assuming no redemptions by public shareholders), Alpha Tau is expected to have approximately $362 million of cash on the balance sheet.

- Net proceeds are to be used for further expansion of Alpha Tau's clinical strategy including the pursuit of FDA marketing authorization, a broad array of R&D activities, expanding manufacturing capacity and preparing for commercialization, and are expected to provide cash runway at least into 2024.

- All Alpha Tau shareholders will retain 100% of their equity holdings in the public company.

- Alpha Tau will continue to be led by its current management team, and upon closing, it is expected that HCC Chairman Dr. David M. Milch will be appointed to the Alpha Tau Board of Directors.

- The proposed business combination is expected to be completed by the end of 2021, upon which Alpha Tau is expected to be listed on Nasdaq.

JERUSALEM and WILMINGTON, Del., July 8, 2021 /PRNewswire/ -- Alpha Tau Medical Limited ("Alpha Tau"), the developer of the pioneering alpha-radiation cancer therapy Alpha DaRT™, and Healthcare Capital Corp. ("HCC") (Nasdaq: HCCC), a special purpose acquisition company, today announced they have entered into a definitive business combination agreement (the "Business Combination"). Upon closing of the Business Combination, Alpha Tau is expected to be listed on the Nasdaq.

Alpha Tau's proprietary Alpha DaRT™ (Diffusing Alpha-emitters Radiation Therapy) enables highly potent and conformal alpha-irradiation of solid tumors through the intra-tumoral insertion of radium-224 impregnated sources mainly affecting the tumor, sparing the healthy tissue around it. In the company's first-in-human clinical trial for Squamous Cell Carcinoma ("SCC") tumors of the skin & oral cavity exhibited 100% overall response rate and approximately 78% complete response rate. In June 2021, Alpha Tau received FDA Breakthrough Device Designation for the use of Alpha DaRT™ in the treatment of SCC of the skin and oral cavity without curative standard of care.

Alpha Tau has developed a robust clinical trial strategy with leading global centers, including its flagship US multi-center feasibility study currently ongoing, led at Memorial Sloan Kettering Cancer Center in New York, which recently enrolled its first patient.

A group of Healthcare-focused financial and strategic investors have committed to participate in the transaction through a fully committed ordinary share PIPE of approximately $92 million at $10.00 per share. Investors in the PIPE include Yozma Investment Co. (part of Yozma Group Korea) and Grand Decade Developments (an affiliate of China Grand Pharmaceutical and Healthcare Holdings) as well as other leading technology investors including OurCrowd, Regah Ventures and the co-founders of Apax Partners, Alan Patricof and Sir Ronald Cohen. Medison Group, an early supporter of Alpha Tau and global pharma company that provides access to highly innovative therapies to patients in international markets, is also an investor in the PIPE.

"Following the recent enrollment of the first patient in our flagship US feasibility study and receipt of FDA Breakthrough Device Designation, this transaction represents another significant milestone on Alpha Tau's journey to transform the treatment of solid tumors through the precision delivery of alpha radiation. We are grateful to the outstanding team at HCC, whose cadre of experienced and well-regarded professionals have provided superb execution and continued support for Alpha Tau, and we are excited for Dr. David M. Milch to join as our newest member of the Board of Directors upon the closing of the business combination. We thank our investors, both new joiners as well as those who have supported us for years, who continue to demonstrate their faith in the company and its leadership," said Uzi Sofer, CEO and Chairman of Alpha Tau.

"The completion of this transaction will allow the company to realize its vision and implement the clinical development plans and construction of our manufacturing plants around the world, in order to bring hope to millions of patients around the world."

"This transaction ensures that we are well capitalized to accelerate our ambitious plans across multiple fronts," said Raphi Levy, CFO of Alpha Tau. "We look forward to delivering continued clinical momentum and hope for patients as we evolve into a public company."

"We are excited about Alpha Tau's unique therapy, which has generated a response observed across a wide array of solid tumors in pre-clinical studies, with minimal side effects, positioning it to potentially become a vital weapon in the battle against cancer," said Dr. David M. Milch. "After evaluating many opportunities in the healthcare industry, we believe that Alpha Tau stands out as the best choice for a business combination due to its proprietary technology, rapid clinical and product development and easy to administer treatment solution for the great number of cancer patients worldwide."

"It was a pleasure to work with the team at HCC as their due diligence advisor following my departure as Commissioner of the FDA in January 2021," said Dr. Stephen M. Hahn. "My background as a medical and radiation oncologist helped me immediately appreciate the potential of Alpha Tau's therapy in providing a solution for a potentially significant number of patients, including those with untreatable or difficult to treat tumors, whether alone or in combination with other therapies such as immunotherapies. I would expect the product to be well received by the clinical community because of the potential applications, modest side effect profile, and demonstrated potency of the Alpha DaRT"

Proceeds of the business combination and the PIPE will be primarily used to:

• advance ongoing, and launch, new clinical trials;

• continue existing, and initiate additional, clinical and research collaborations;

• develop and expand global manufacturing capacity;

• develop KOL centers of excellence; and

• prepare for commercialization efforts.

About Alpha Tau

Founded in 2016, Alpha Tau Medical Ltd, is an Israeli oncology therapeutics company that focuses on research, development, and commercialization of the Alpha DaRT™ technology for the treatment of solid tumors.

Alpha DaRT™(Diffusing Alpha-emitters Radiation Therapy) is an innovative technology that enables the highly potent and uniquely conformal alpha-irradiation of solid tumors. The treatment is delivered by intratumoral insertion of radionuclide Radium-224, which leads to the release and diffusion of daughter radioisotopes that emit alpha particles. These alpha particles have the capacity to destroy solid tumors. Since the alpha-emitting atoms diffuse only a short distance in tissue, Alpha DaRT mainly damages the tumor, while sparing the healthy tissue around it.
