ProSomnus® Debuts as Publicly Traded Company Focused on Disrupting Obstructive Sleep Apnea Treatment Market with Patient-preferred Precision Oral Appliance Therapy Devices

 ProSomnus, Inc. (“the Company”), a pioneer in precision medical devices for the treatment of Obstructive Sleep Apnea (OSA), today announced the completion of its previously announced business combination with Lakeshore Acquisition I Corp. (“Lakeshore”) (Nasdaq: LAAA), a publicly traded special purpose acquisition company. ProSomnus will commence trading on the Nasdaq Global Market under the symbol “OSA” on Dec. 7, 2022. The business combination, which was approved by Lakeshore’s shareholders on Dec. 2, 2022, along with the convertible debt issued in connection with the transaction, provides access to capital that will be used to drive the Company’s multi-faceted commercial expansion.

A key reason for going public was to bring to fruition ProSomnus’ ambitious growth plans. ProSomnus will use the capital to scale up its business by expanding and investing in three key areas: technology, sales and manufacturing. ProSomnus is planning to open its new design and manufacturing facility next month, which will be optimized for mass-customized manufacturing, AI-driven design and 3D robotic milling This will enable the Company to increase manufacturing capacity four-fold for its Oral Appliance Therapy (“OAT”) devices to meet the rising demand of providers and patients. Additional capital also will allow the Company to grow its international presence as it continues to attract providers in the multi-billion dollar North American market, as well as globally, representing a $50 billion dollar market opportunity.

ProSomnus will continue to be led by Len Liptak, Co-Founder and Chief Executive Officer, and Laing Rikkers, Co-Founder and Executive Chair, William Johnson, Audit Chair and Director, and Len Hedge, Director. Mr. Johnson continues to contribute his financial expertise in medical technology and public company management, and Hedge remains invaluable to the team offering experience from his thirteen years managing the operations of Align Technology’s Invisalign products.

Effective today, ProSomnus will add to its Board of Directors including the appointment of the following individuals who bring a depth and breadth of talent to the team:

• Heather Rider will serve as Compensation Committee Chair. Ms. Rider is currently on the Board of Directors of publicly traded companies including Inogen, Inc., an oxygen therapy technology manufacturer, and served on the Board of Directors of Intricon Corporation, a micro-medical technology component manufacturer, until its sale earlier this year.
• Steve Pacelli will serve as Nominating and Governance Committee Chair. Mr. Pacelli is Executive Vice President and Managing Director of Dexcom Ventures, a leader in continuous glucose monitoring for people with diabetes.
• Jason Orchard is the Managing Director of Spring Mountain Capital, an investment management firm specializing in alternative asset investing.

“We are pleased to welcome a new group of carefully selected directors who bring diverse and pertinent experience to ProSomnus’ leadership team at an important inflection point in the Company’s history. Heather Rider has spent eight years in the respiratory sector and has significant human resources capabilities, which we will leverage as we scale our team for future growth.   Steve Pacelli’s seventeen years at Dexcom will provide key insights into remote patient monitoring as ProSomnus develops and launches its next-generation device, which will be the first precision OAT with remote monitoring – a key innovation for sleep physicians seeking improved disease management capabilities. Finally, Jason Orchard’s extensive experience on Wall Street offers valuable perspectives into the capital markets as we accelerate our growth. We are fortunate to have such a strong group of leaders and I am confident that they will be important contributors in the development and maturation of the Company in the coming years,” said Laing Rikkers, ProSomnus Co-Founder and Executive Chair.

ProSomnus’ FDA-cleared, Precision OAT devices are a practical alternative to legacy oral devices and CPAP machines, and can result in more effective treatment and superior patient compliance. They reposition and stabilize the jaw during sleep, improving airflow through a patient's pharyngeal space. ProSomnus Precision OAT devices consist of maxillary and mandibular aligners that are precision-manufactured with twin-mated posts, and are digitally milled to be patient-specific. Prescribed advancements can be achieved by removing the current upper- or lower-device arch and inserting the next arch in the mandibular advancement series.

“With more than 175,000 devices prescribed and a growing network of over 4,000 medical providers, ProSomnus is actively disrupting the massive OSA treatment market and, as a public company, we will now have the ability to fuel even more growth,” said Len Liptak, ProSomnus Co-Founder and Chief Executive Officer. “With an estimated one billion people suffering from OSA worldwide, this is a tremendous population in need of a viable therapy, as untreated OSA is known to exponentially increase mortality. Becoming publicly traded will help fund expanded infrastructure and groundbreaking clinical studies – including our FDA-reviewed, landmark Severe OSA Study (SOS) and Frontline OSA Treatment (FLOSAT) study – that will help us further address OSA on a global scale.”

“In addition to a growing body of research, the increased adoption of ProSomnus Precision OAT devices suggests that this type of therapy is a patient-preferred alternative to legacy OSA treatment options,” continued Liptak “In 2022, we achieved several important product milestones, receiving FDA 510(k) clearance for our EVO [PH] Sleep and Snore device, and continuing the development of our next-generation device, which will feature remote patient monitoring. Access to the public capital markets will allow us to continue innovating and providing patients with cutting-edge features that can fundamentally improve the treatment and management of OSA.”

About OSAOSA is the recurring collapse of the airway during sleep, resulting in oxygen shortages and abrupt awakenings accompanied by gasping or choking. In addition to daytime sleepiness, OSA is associated with serious comorbidities, including heart failure, stroke, hypertension, morbid obesity and type 2 diabetes. Patients with untreated OSA are 23 times more likely to suffer a heart attack and four times more likely to have a stroke. It is estimated that more than one billion people worldwide and over 74 million people in North America suffer from OSA. Approximately 56 million of those 74 million people in North America are undiagnosed.
