The Coretec Group and Core Optics Share Exchange Moves Toward Closing; Provides Initial Sales Forecast

ANN ARBOR, Mich., June 28, 2024(OTCQB: CRTG), developers of silicon anode active materials for lithium-ion batteries and cyclohexasilane (CHS) for electric vehicles (EVs), cleantech, and emerging tech applications, today announced that the share exchange transaction with Core Optics, LLC has progressed toward the final closing, and can now publicly share Core Optics' strong revenue forecast for calendar year 2024 and hyper growth in 2025. The share exchange transaction is in its final stages of documentation and due diligence, as already disclosed certain closing conditions have been resolved and others are being finalized. Once the few final conditions have been satisfied, the final closing will take place.

Core Optics is forecasting its full year aggregate revenues of approximately:

• $8M USD (eight million dollars) for fiscal year 2024; and
• $16M USD (sixteen million dollars) for fiscal year 2025.

The majority of this revenue growth is expected to occur in the automotive market, a global customer audience that is synergistic with the Endurion battery program. Core Optics has also expanded its workforce and physical plant to meet the demand and fulfill current orders.

This new partnership is already expanding The Coretec Group's Endurion battery outreach, as the Core Optics team has already engaged in significant discussions with cathode manufacturers in South Korea. These manufacturers have expressed interest in partnering with Coretec to utilize Endurion in their battery developments.

"The demand for our CCM testing equipment in the automotive manufacturing sector is driving our revenue growth. As a result, we are aggressively ramping up our production to meet the demand and work through our backlog," said Dr. Kim, Chief Executive Officer of Core Optics, LLC. "As we manage this growth, we will continue to pursue opportunities in mobile devices and drones, as well as using our technology in battery testing equipment."

Unaudited preliminary results for Core Optic's year ended December 31, 2023 and first quarter ended March 31, 2024 are as follows:

? Unaudited revenue was approximately $1.81 million for its intra-year-inception to December 31, 2023 FYE period, and unreviewed revenues was approximately $0.88 million for the three months ended March 31, 2024. The revenue in 2023 was expectedly low due to Core Optics' rollout of its electric vehicle products and services. The increase in revenue during the first quarter ended March 31, 2024 is primarily due to an increase in customer orders and the volume of customers in electric automotive markets.

- Unaudited operating profit for its intra-year-inception to December 31, 2023 FYE period was approximately $4,500. Unreviewed operating profit for the three months ended March 31, 2024 was approximately $18,400.

- Unaudited cash was approximately $907,000 as of December 31, 2023, and unreviewed cash was approximately $48,000 for the first quarter ended March 31, 2024. The reduction in cash between periods was due to significant capital expenditures made towards fulfilling customer purchase orders that were delivered in the first quarter and will continue to be delivered in subsequent periods.
