Geron Corporation executive Michelle Robertson, EVP and Chief Financial Officer, reported several equity transactions. On February 18, 2026, 27,500 restricted stock units vested and converted into the same number of common shares, with each RSU representing one share. On the same date, 9,855 common shares were sold at $1.94 per share solely to cover tax withholding obligations under a mandatory sell-to-cover policy, rather than as a discretionary sale. Separately, on February 17, 2026, she received a stock option grant for 1,660,000 shares, vesting in 48 equal monthly installments starting March 17, 2026, contingent on continued service.
Geron Corp received an updated ownership report from Deep Track Capital and related entities showing a sizable passive stake in its common stock. Deep Track Capital, Deep Track Biotechnology Master Fund and David Kroin together report beneficial ownership of 32,511,271 Geron shares, representing 5.09% of the company’s common stock.
The filing states they hold only shared voting and dispositive power over these shares, with no sole authority. The ownership percentage is calculated using 638,355,275 Geron shares outstanding as of November 4, 2025. The reporting persons certify the position is not held for the purpose of changing or influencing control of Geron.
Geron Corporation furnished an update outlining its financial outlook and investor communications for 2026. The company issued a press release with 2026 financial guidance, including expected RYTELO® net product revenue and total operating expenses for the year. This gives the market a view of how management currently sees revenue from its RYTELO franchise and the cost base needed to support the business.
Geron also provided a January 2026 corporate slide presentation that will be used in meetings with analysts and investors during the 44th Annual J.P. Morgan Healthcare Conference. Both the press release and the slides are furnished as exhibits rather than filed, meaning they are not automatically subject to certain Exchange Act liabilities or incorporated into other SEC reports unless specifically referenced.
Geron Corporation amended its existing Pharmakon-backed loan facility to extend key dates while keeping core terms the same. The 5-year senior secured term loan totals up to $250.0 million, split into a funded $125.0 million Tranche A, a $75.0 million Tranche B available at the company’s option subject to limited conditions, and a $50.0 million Tranche C that becomes available once a specified trailing twelve-month RYTELO™ revenue milestone is reached.
The amendment moves the outside date for drawing Tranche B and, once available, Tranche C from December 31, 2025 to July 30, 2026, giving Geron more time to access these funds. It also pushes the Makewhole Date, used to calculate early prepayment charges, from November 1, 2026 to May 1, 2027, while leaving the existing prepayment premium schedule and other loan terms unchanged.
Geron Corporation is implementing a strategic restructuring plan that includes reducing its workforce by about one-third from approximately 260 employees and expects about $18 million in restructuring and related charges. The board unanimously approved the plan on December 10, 2025, and the company began notifying affected employees on December 16, 2025, with the reduction expected to be substantially complete in the first quarter of 2026.
The charges, driven mainly by one-time severance, healthcare and related employee costs, are expected to affect results in the fourth quarter of 2025 and first quarter of 2026, with most cash payments occurring through the first quarter of 2026. Geron states the charges are not currently expected to include non-cash equity-based compensation and notes that actual costs, timing, and the business impact of the plan could differ materially from its estimates.
Geron Corporation reported Q3 2025 results, showing continued commercialization of RYTELO. Total revenues were $47.3 million, driven by net product revenue of $47.2 million. The company recorded a net loss of $18.4 million (basic and diluted loss per share of $0.03), narrowing from the prior year period.
Operating expenses reflected commercial scale-up: cost of goods sold were $1.0 million, research and development $21.1 million, and selling, general and administrative $39.0 million. As of September 30, 2025, Geron held $421.5 million in cash, cash equivalents, restricted cash and marketable securities, with inventory of $95.4 million supporting RYTELO supply. Noncurrent debt was $119.3 million, and stockholders’ equity stood at $248.7 million. Interest expense rose to $8.6 million in the quarter, reflecting financing costs alongside growing product sales.
