(Nasdaq: LYEL), a late-stage clinical company advancing a pipeline of next-generation chimeric antigen receptor (CAR) T-cell therapies for patients with cancer, today announced it has closed the sale of an additional $50 million of shares of its common stock to investors from its July 2025 equity private placement of up to $100 million, following achievement of a clinical milestone within its PiNACLE pivotal trial evaluating rondecabtagene autoleucel (ronde-cel) in patients with relapsed/refractory large B-cell lymphoma (LBCL) in the third- or later-line setting. The Company also announced the appointment of Smital Shah as its Chief Financial and Business Officer, effective March 9, 2026.

“Smital’s deep expertise in navigating complex financial landscapes and her proven track record of strategic leadership in the biotechnology industry make her the ideal partner to guide Lyell’s financial strategy as we enter a transformative year of execution,” said Lynn Seely, M.D., President and CEO of Lyell. “The attainment of the second $50 million tranche of the private placement is evidence of Lyell’s continued advancement toward significant value inflection points. Smital’s insights will be invaluable in ensuring we remain well-capitalized and operationally disciplined to deliver on our mission of bringing next-generation cell therapies to patients with cancer.”

Closing of Additional $50 Million Equity Private Placement Following Achievement of Clinical Milestone for Ronde-cel
Under the terms of the securities purchase agreement for the July 2025 equity private placement of up to $100 million, and following the initial closing of $50 million, Lyell held the right to require investors to purchase an additional $50 million of common stock upon the achievement of a clinical milestone for ronde-cel, a dual-targeting CD19/CD20 CAR T-cell therapy in pivotal clinical development for patients with LBCL. Following the successful achievement of this clinical milestone, Lyell exercised this right and the investors purchased these shares from Lyell at a purchase price per share of $25.61, resulting in gross proceeds of approximately $50 million, bringing the total equity private placement proceeds to approximately $100 million. With the closing of this additional tranche, Lyell expects its cash, cash equivalents and marketable securities to be sufficient to meet working capital and capital expenditure needs into the second quarter of 2027.
