Biohaven Ltd. is a clinical-stage biopharmaceutical company focused on immunology, obesity, neuroscience and oncology, reporting continued losses as it advances a broad R&D portfolio. For the quarter ended June 30, 2026, it recorded a net loss of $137.3 million and for the first half of 2026 a net loss of $267.8 million, driven primarily by research and development expense of $204.6 million over six months. Losses narrowed versus 2025 as R&D spending declined.
Liquidity is anchored by cash, cash equivalents and marketable securities of $267.9 million as of June 30, 2026, with management expecting these resources to fund operations for at least one year from the financial statement issuance date. Operating cash outflows were $235.0 million in the first half, partially offset by $178.9 million of equity raised through at-the-market offerings. The balance sheet shows total assets of $370.7 million and notes payable at fair value of $259.5 million under a revenue- and milestone-based Note Purchase Agreement tied to troriluzole, contributing to fair value losses in other expense. Shareholders’ equity declined to $12.2 million as accumulated deficit increased to $2.35 billion and the company continues to rely on external capital, including a large remaining ATM capacity.

Biohaven Ltd. provided extensive research and development updates, highlighting new clinical data across epilepsy, autoimmune and neuroscience programs. Its Kv7.2/7.3 activator opakalim in idiopathic generalized epilepsy tripled median time to a second generalized tonic-clonic seizure to 141 days versus 47 days on placebo in a small randomized trial and showed no somnolence, dizziness or fatigue. In focal epilepsy, an open-label extension analysis found 54% of six‑month completers on opakalim 75 mg once daily achieved at least a 50% seizure reduction, with low central nervous system adverse event rates compared with other antiseizure medicines. Biohaven also reported Phase 1b data for its extracellular degraders: BHV‑1300 reduced Graves’ disease TSHR‑IgG1 autoantibodies by over 80% with associated normalization of thyroid hormones, while BHV‑1400 lowered pathogenic Gd‑IgA1 by more than 60% within 48 hours and 70% within one month in IgA nephropathy, alongside early improvements in kidney function markers.
