Altaris buyout at $18.50 cash anchors SLP; old accounting probe resurfaces
Altaris to buy SLP for $375M all-cash Altaris agreed to acquire Simulations Plus for about $375 million, or $18.50 a share in cash — a 26% premium to the 60-day average price. The board unanimously approved it, with closing expected in late 2026. This sets a firm floor under the stock and is the main reason it trades near the deal price.
The buyout is the single biggest force setting SLP's price now.
Agentic AI layer built with NVIDIA BioNeMo Simulations Plus is building an AI 'agent' layer for its Composer platform using NVIDIA's BioNeMo toolkit, expanding a May 2026 partnership.

Q3 swing to profit on no impairment charge Simulations Plus reported Q3 net income of $3.58 million versus a $67.32 million loss a year earlier, which had included a $77.22 million write-down. Revenue rose 7% to $21.89 million, but adjusted earnings fell to $0.30 a share from $0.45. Profitability improved, yet the core business still shows pressure.

Investor investigation revives old accounting worries Johnson Fistel is investigating Simulations Plus over a 2025 revenue guidance cut, a large net loss, and the dismissal of auditor Grant Thornton, which flagged unresolved segment-reporting and internal-control issues. These are old disclosures, but the probe keeps the accounting overhang in view and is a real counterweight to the buyout news.
It is the main risk factor that could complicate or delay the deal.
