Second Quarter 2026 Financial Results

In May 2026, the Company effected a one-for-eleven reverse stock split of its common stock and reduced its authorized shares of common stock from 500,000,000 to 100,000,000. All share and per-share amounts in this press release reflect the reverse stock split.

Net loss for the three months ended June 30, 2026 was $4.5 million, or $(0.39) per share, which included $0.1 million in stock-based compensation, compared to a net loss of $1.9 million, or $(5.45) per share, for the same period in 2025. For the six months ended June 30, 2026, net loss was $8.3 million, compared to $3.6 million for the same period in 2025.

Research and development (R&D) expenses were $2.8 million for the three months ended June 30, 2026, compared to $0.9 million for the same period in 2025. The increase was primarily related to increased clinical trial expenses in support of the Company's exaluren program, as well as increases in personnel costs and preclinical research and development activities.

General and administrative (G&A) expenses were $1.6 million for the three months ended June 30, 2026, compared to $0.7 million for the same period in 2025. The increase was primarily related to higher professional and consulting fees, including legal, audit and tax fees, and increased personnel costs.

Cash position. As of June 30, 2026, the Company had cash and cash equivalents of $62.0 million, which includes approximately $58.3 million in net proceeds from the June 2026 public offering. The Company believes its cash and cash equivalents will be sufficient to fund its operations into mid-2028.
