Geron Corporation Reports Third Quarter 2024 Financial Results and Recent Business Highlights

Achieved $28.2 million in RYTELO™ (imetelstat) net product revenue in first full quarter of sales

Received $250 million in gross proceeds from synthetic royalty and debt financings with Royalty Pharma and Pharmakon Advisors, with access to an additional $125 million in debt

FOSTER CITY, Calif., November 7, 2024 -- Geron Corporation (Nasdaq: GERN), a commercial-stage biopharmaceutical company aiming to change lives by changing the course of blood cancer, today reported financial results for the third quarter of 2024 and recent business highlights.

"This has been a transformative year for Geron, following our first FDA approval and commercial launch of RYTELO in June. The initial full quarter of product revenue from our U.S. launch exceeded our expectations and demonstrates strong execution as a commercial company. These results also reflect the high unmet need in lower-risk MDS and the compelling value proposition of RYTELO for hematologists and patients, giving us confidence in future continued demand and momentum for RYTELO," said John A. Scarlett, M.D., Geron's Chairman and Chief Executive Officer. "We were also pleased to announce this morning the completion of important synthetic royalty and debt financing transactions with Royalty Pharma and Pharmakon Advisors. We believe that the favorable terms in these transactions reflect the significant commercial potential of RYTELO and provide us with critical flexibility to fuel continued growth and invest in our future."

Upcoming Milestones

Third Quarter 2024 Financial Results

As of September 30, 2024, we had approximately $378.9 million in cash, cash equivalents, restricted cash and marketable securities. On a pro forma basis, including gross proceeds from the upfront payment under the Royalty Pharma Agreement and the first tranche of the Pharmakon loan and after repayment of our existing debt, we had approximately $542.4 million in cash, cash equivalents, restricted cash, and marketable securities as of September 30, 2024.

Net Loss

For the three and nine months ended September 30, 2024, the Company reported a net loss of $26.4 million, or $0.04 per share, and $149.2 million, or $0.23 per share, respectively, compared to $44.8 million, or $0.08 per share and $132.2 million, or $0.23 per share, respectively, for the three and nine months ended September 30, 2023.

Revenues

Total product revenue, net for the three and nine months ended September 30, 2024, was $28.2 million and $29.0 million, respectively.

Total net revenue for the three and nine months ended September 30, 2024, was $28.3 million and $29.5 million, respectively, compared to $164,000 and $214,000 for the same periods in 2023. The increase in revenue is due to product revenue from U.S. sales of RYTELO, which was available for prescribers to order from specialty distributors as of June 27, 2024.

Operating Expenses

Total operating expenses for the three and nine months ended September 30, 2024, were $56.5 million and $183.1 million, respectively, compared to $47.8 million and $139.9 million for the same periods in 2023.

Cost of goods sold was approximately $456,000 and $473,000 for the three and nine months ended September 30, 2024, respectively, which consisted of costs to manufacture and distribute RYTELO.

Research and development expenses for the three and nine months ended September 30, 2024, were $20.2 million and $80.3 million, respectively, and $29.4 million and $92.1 million, for the same periods in 2023. The decrease is primarily due to manufacturing and quality costs that were capitalized in the current period due to FDA approval of RYTELO, compared to being expensed in the prior period.

Selling, general and administrative expenses for the three and nine months ended September 30, 2024, were $35.9 million, and $102.4 million, respectively, and $18.4 million and $47.7 million for the same periods in 2023. The increase in selling, general and administrative expenses primarily reflects higher commercial launch expenses, and increases in headcount and related expenses in connection with the U.S. launch of RYTELO.

Interest income was $4.9 million and $14.4 million for the three and nine months ended September 30, 2024, respectively, compared to $5.0 million and $13.6 million for the same periods in 2023. The decrease in interest income for the three months ended September 30, 2024, compared to the same period in 2023 was due to a decrease in interest rates. The increase in interest income for the nine months ended September 30, 2024, compared to the same period in 2023, primarily reflects a larger marketable securities portfolio with the receipt of net cash proceeds from the underwritten offering completed in March 2024, as well as higher yields from recent marketable securities purchases.

Interest expense was $3.0 million and $9.8 million for the three and nine months ended September 30, 2024, respectively, compared to $2.1 million and $6.0 million for the same periods in 2023. The increase in interest expense primarily reflects rising interest rates.

2024 Financial Guidance

For fiscal year 2024, we expect total operating expenses to be in the range of approximately $260 million to $270 million, which includes non-cash items such as stock-based compensation expense, amortization of debt discounts and issuance costs, and depreciation and amortization.

Based on our current operating plans and assumptions, we believe that our existing cash, cash equivalents, and marketable securities (including the $250 million gross proceeds received under the Pharmakon loan and Royalty Pharma agreements), together with anticipated revenues from U.S. sales of RYTELO, will be sufficient to fund our projected operating requirements for at least the next 12 months from the date of this press release. We believe that our projected financial resources will be sufficient to support commercial launch of RYTELO in the U.S. and potential launch in the EU, complete the Phase 3 IMpactMF trial in relapsed/refractory MF, invest in supply chain redundancy for RYTELO, and fund our general working capital requirements.

About RYTELO (imetelstat)

RYTELO (imetelstat) is an FDA-approved oligonucleotide telomerase inhibitor for the treatment of adult patients with low-to-intermediate-1 risk myelodysplastic syndromes (LR-MDS) with transfusion-dependent anemia requiring four or more red blood cell units over eight weeks who have not responded to or have lost response to or are ineligible for erythropoiesis-stimulating agents (ESAs). It is indicated to be administered as an intravenous infusion over two hours every four weeks.

RYTELO is a first-in-class treatment that works by inhibiting telomerase enzymatic activity. Telomeres are protective caps at the end of chromosomes that naturally shorten each time a cell divides. In LR-MDS, abnormal bone marrow cells often express the enzyme telomerase, which rebuilds those telomeres, allowing for uncontrolled cell division. Developed and exclusively owned by Geron, RYTELO is the first and only telomerase inhibitor approved by the U.S. Food and Drug Administration.

About Geron

Geron is a commercial-stage biopharmaceutical company aiming to change lives by changing the course of blood cancer. Our first-in-class telomerase inhibitor RYTELO™ (imetelstat) is approved in the United States for the treatment of certain adult patients with lower-risk myelodysplastic syndromes (LR-MDS) with transfusion dependent anemia. We are also conducting a pivotal Phase 3 clinical trial of imetelstat in JAK-inhibitor relapsed/refractory myelofibrosis (R/R MF), as well as studies in other myeloid hematologic malignancies. Inhibiting telomerase activity, which is increased in malignant stem and progenitor cells in the bone marrow, aims to reduce proliferation and induce death of malignant cells.

About IMpactMF Phase 3

IMpactMF is an open label, randomized, controlled Phase 3 clinical trial with registrational intent. The trial is designed to enroll approximately 320 patients with intermediate-2 or high-risk myelofibrosis (MF) who are relapsed after or refractory to prior treatment with a JAK inhibitor, also referred to as relapsed/refractory MF. Patients will be randomized to receive either imetelstat or best available therapy. The primary endpoint is overall survival (OS). Key secondary endpoints include symptom response, spleen response, progression free survival, complete remission, partial remission, clinical improvement, duration of response, safety, pharmacokinetics, and

patient reported outcomes. IMpactMF is currently enrolling patients. For further information about IMpactMF, including enrollment criteria, locations and current status, visit ClinicalTrials.gov/NCT04576156.
