Perspective Therapeutics (formerly known as Isoray, Inc.) Announces Financial Results for the Quarter ended December 31, 2022

Perspective Therapeutics, Inc.

Fiscal Calendar Year Changes from June to December Year End

RICHLAND, Wash. and CORALVILLE, Iowa, Feb. 16, 2023 (GLOBE NEWSWIRE) -- Perspective Therapeutics, Inc. (formerly known as Isoray, Inc.) (NYSE AMERICAN: ISR), a precision oncology company developing alpha-particle therapies and complementary diagnostic imaging agents and an innovator in seed brachytherapy powering expanding treatment options for multiple cancers, today announced unaudited financial results for the three months ended December 31, 2022.

“The fourth quarter represented a transformational period leading up to the completed merger between Isoray and Viewpoint Molecular Targeting. In the Company’s core brachytherapy business lack of orders from our largest customer and post-COVID recovery efforts resulted in a sales decline. We will continue to advocate for awareness of the long-term benefits of Cesium-131 brachytherapy treatment across respective indications and in particular for prostate cancer as an alternative to radical prostatectomy,” said Perspective Therapeutics CEO Thijs Spoor.

“Looking forward, as we advance the mission of the combined companies, we are introducing a new wave of alpha-particle radiotherapy that represents an entirely new class of theranostics developed to treat a broad class of cancers. Strong scientific fundamentals continue to build a mounting body of supporting evidence for Perspective’s targeted alpha therapy (TAT) precision oncology approach to changing the treatment landscape for melanoma and neuroendocrine tumors. Perspective Therapeutics’ two-step approach utilizing targeted peptides to diagnose and deliver extremely powerful radiotherapy holds the promise of delivering precision targeted medicine from the inside out. We firmly believe that by improving efficacy and reducing toxicity across a broad class of cancer treatments, we will not only unlock shareholder value in the Company but also transform the radiotherapy treatment paradigm for patients. I am confident the best is yet to come,” concluded Perspective Therapeutics CEO Thijs Spoor.

Financial Results for Isoray, Inc. for the Quarter Ended December 31, 2022

Revenue for the three months ended December 31, 2022 decreased 35% to $1.84 million versus $2.82 million in the prior year comparable period. The year over year decline in revenue was the result of sales to treat prostate cancer which declined 50% year over year primarily due to a lack of orders from our largest customer during the quarter. Prostate brachytherapy represented 58% of total revenue for the three months ended December 31, 2022 compared to 76% in the prior year comparable period. Non-prostate brachytherapy revenue increased 14% versus the prior year comparable period. The majority of non-prostate brachytherapy revenue in the three-month period was comprised of sales to treat brain cancer, including sales of GammaTile^® Therapy.

Gross profit as a percentage of revenues was 22.0% for the three months ended December 31, 2022 versus 43.3% in the prior year comparable period. Gross profit decreased to $0.40 million versus $1.22 million in the comparable year ago quarter. The year over year decrease was primarily the result of the decrease in core prostate sales resulting from lower order volumes.

Total operating expenses in the three months ended December 31, 2022 were $3.70 million compared to $2.86 million in the prior year period. Total research and development expenses increased 15% versus the prior year comparable period. The increase in research and development expenses was primarily the result of increased payroll expense due to annual merit increases and travel related expenses versus the prior year comparable period.

Sales and marketing expenses increased 16% versus the prior year comparable period. The increase in sales and marketing expenses was driven primarily by an increase in travel, conventions, and tradeshow expenses, increased consulting expenses, and increased payroll and benefits expense due to annual merit increases versus the prior year comparable period. General and administrative expenses increased 35% versus the prior year comparable period. The increases in general and administrative expenses were primarily the result of legal, proxy solicitation and other public company related expenses associated with the merger with Viewpoint Molecular Targeting, Inc. Also contributing to the increase were payroll and benefits expense due to annual merit increases and increased travel. In addition, the Company wrote-off some software implementation costs as the Company will change certain systems due to the merger.

The net loss for the three months ended December 31, 2022 was $2.90 million or ($0.02) per basic and diluted share versus a net loss of $1.60 million or ($0.01) per basic and diluted share in the comparable prior year period. Basic and diluted per share results are based on weighted average shares outstanding of approximately 142.1 million for the three months ended December 31, 2022 versus 142.0 million in the comparable prior year period.

Cash, cash equivalents, and short-term investments as of December 31, 2022, totaled $43.8 million and the Company had no long-term debt. Stockholders’ equity totaled $55.0 million.

About Perspective Therapeutics, Inc.
Perspective Therapeutics, Inc., formerly known as Isoray, Inc., is a medical technology and radiopharmaceutical company that is pioneering advanced treatment applications for cancers throughout the body. The Company is the sole producer of Cesium-131 brachytherapy seeds and has a proprietary technology that utilizes the isotope lead-212 to deliver powerful alpha radiation specifically to cancer cells via specialized targeting peptides. The Company is also developing complementary imaging diagnostics that incorporate the same targeting peptides which provide the opportunity to personalize treatment and optimize patient outcomes. This “theranostic” approach enables the ability to see the specific tumor and then treat it to potentially improve efficacy and minimize toxicity associated with many other types of cancer treatments.

The Company’s melanoma (VMT01) and neuroendocrine tumor (VMT-a-NET) programs are entering Phase 1/2a imaging and therapy trials for the treatment of metastatic melanoma and neuroendocrine tumors at several leading academic institutions. The Company has also developed a proprietary lead-212 generator to secure isotope supply for clinical trial and commercial operations.
