Aligos Therapeutics reported Q2 2026 results marked by its first substantial licensing revenue but continued operating losses and a short cash runway. Revenue was driven by $27.8 million from a new license agreement with Xiamen Amoytop Biotech for pevifoscorvir sodium in Greater China; there was no Q2 customer collaboration revenue. Operating expenses rose to $29.7 million, including $24.1 million of research and development as the Phase 2 B‑SUPREME trial for pevifoscorvir sodium ramped, while general and administrative costs were stable at $5.6 million.
Q2 loss from operations was $1.9 million, and after a $3.0 million non‑cash gain from remeasuring 2023 Common Warrants and a $2.8 million tax provision tied largely to Amoytop withholding taxes, the net loss was $1.5 million (basic and diluted loss per share of $0.14). For the first six months of 2026, the company recorded a net loss of $24.5 million on operating cash outflows of $48.1 million.
Cash and cash equivalents were $30.4 million at June 30, 2026, with no short‑term investments outstanding and $27.8 million in accounts receivable from the Amoytop license. Management states that existing cash plus the $25.0 million net upfront received from Amoytop in July 2026 are expected to fund planned operations only into the fourth quarter of 2026, which raises substantial doubt about the company’s ability to continue as a going concern absent additional capital. The pipeline advanced, with regulatory designations and ongoing studies in chronic hepatitis B and MASH, but development remains in clinical stages with no product sales.
Aligos Therapeutics reported second quarter 2026 results and detailed progress in its hepatitis B pipeline. The company strengthened its balance sheet with a $25 million upfront payment from an exclusive Greater China license for pevifoscorvir sodium and a $3 million milestone tied to IND approval for ALG-170675.
Pevifoscorvir sodium received Breakthrough Therapy Designation in China, complementing U.S. Fast Track status, and the Phase 2 B-SUPREME trial completed enrollment with 131 HBeAg+ and 114 HBeAg- participants, with topline data expected in late Q3 2027. ALG-170675, a next-generation antisense oligonucleotide, will enter Phase 1 studies in China funded by partner Amoytop, while Aligos retains ex-Greater China rights.
Cash, cash equivalents and investments were $30.4 million as of June 30, 2026, excluding the $25 million upfront received in July, and are expected to fund operations into the fourth quarter of 2026. For Q2, Aligos reported a net loss of $1.5 million, compared with $15.9 million a year earlier, with R&D expenses rising to $24.1 million as B-SUPREME advanced.
