AOTI, INC. (the "Company" or "Group" or "AOTI")

California Medicaid Provider ID Awarded

By far the largest Medicaid state in US by enrolled population

Third state this year where the Company has been granted provider ID 

Strong predicate reference site for CMS coverage and further states in commercial roll out

AOTI, INC. (AIM: AOTI), a medical technology group focused on the durable healing of wounds and the prevention of amputations, today announces further progress on its market access and commercial expansion strategy having successfully been granted a new Provider ID in California. This will allow the Company to start to secure insurers and obtain coverage for its TWO₂^® therapy in the state and support the Company's growth in the latter part of 2026.

California is by far the largest Medicaid state by enrolled population with 14.7 million, or 38%, of the population covered by Medi-Cal, California's specific Medicaid programme.¹ This is the third state this year where the Company has been granted provider ID and is in line with its guidance of adding two to three states per year.

Medicaid has evolved to become the largest government funded healthcare program providing comprehensive coverage of health and long-term care to 83 million low-income people in the United States. Medicaid accounts for one-fifth of all US health care spending and covers one quarter of the entire population. Medicaid is jointly funded by states and the federal government but is uniquely administered by each state within broad federal rules.²

Dr. Mike Griffiths, Chief Executive Officer & President of AOTI, Inc., said:

"I am delighted we have been granted Provider ID in our home State of California, which is a significant milestone in our growth strategy and further validation of the unique value proposition we deliver. Securing market access in California is a major achievement and will allow us to begin to deliver the clinical and cost saving benefits of our TWO₂^® therapy to patients, providers and payors in the largest Medicaid market in the US, establishing a strong predicate reference site for CMS coverage where the process is already in progress and, for further states in the Company's commercial roll out."
