INTERNATIONAL ISOTOPES INC. ANNOUNCES FINANCIAL RESULTS FOR THE FIRST QUARTER 2022

The Company Reports A Net Profit Of Approximately $1.2 Million For The First Quarter

And A 41% Increase In Revenue Compared To The Same Period Last Year

IDAHO FALLS, Idaho, May 17, 2022 /PRNewswire/ -- International Isotopes Inc. (OTCQB: INIS) (the "Company") is pleased to announce its financial results for the three months ended March 31, 2022.

Revenue for the three months ended March 31, 2022 was $2,807,441 as compared to $1,992,512 for the same period in 2021, an overall increase of approximately 41%. This increase in revenue was the result of increased revenue in our radiochemical and cobalt segments.  Our net income for the three months ended March 31, 2022, was $1,255,045, compared to net loss of $601,152, for the same period in 2021. This increase in income was the result of increases in revenue in our radiochemical and cobalt product segments, and a gain on the sale of assets previously described in an Asset Purchase Agreement with Pharmalogic Idaho, LLC.

Revenue from the sale of radiochemical products for the three months ended March 31, 2022 increased approximately 146% compared to the same period in 2021.  The increase was the result of growing our customer base, and taking advantage of additional sales opportunities resulting from a supply interruption for radiochemical I-131.  We expect to see steady continued growth in this segment for the remainder of the year, but at a pace slower than that observed in the first quarter.

Revenue from the sale of cobalt products for the three months ended March 31, 2022 increased approximately 45% compared to the same period in 2021.  The increase was primarily due to the timing of cobalt sealed source manufacturing sales, and an increase in the availability of cobalt from the Department of Energy.  We expect to continue to have ample cobalt material availability which should facilitate robust cobalt product sales for the remainder of 2022.

Revenue from nuclear medicine products for the three months ended March 31, 2022, decreased approximately 11% compared to the same period in 2021.  We believe that COVID-19 continued to have an adverse impact of upon our customers during the first three months of 2022.  As the year progresses, we are optimistic that this negative impact will diminish.  We are also taking positive steps to strengthen the Company's marketing of RadQual products by expanding sales staff and marketing efforts throughout our product lines.  We will also continue to expand the range of RadQual products, and explore new markets for sealed source sales.

Steve Laflin, President and CEO of the Company, said, "We are pleased to report strong financial performance in our first quarter.  There are continuing positive signs of increased market share, and improving margins, in both Radiochemical and Cobalt Product segments.  We believe that as the negative impact of COVID-19 diminishes, we will see a rebound in sales of Nuclear Medicine Reference and Calibration Standards. In addition, we are taking aggressive steps to further expand our RadQual product line, and to supplant our marketing and sales efforts both domestically and internationally.  Our financial performance in the first quarter, enhanced by the asset sales agreement with Pharmalogic, has put the Company in what could be considered the best overall financial condition we have seen in the history of the Company.  We expect to continue to see significant positive changes in our balance sheet during the course of the year, and plan to use this financial position to leverage additional new business opportunities."
