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. It aims to speed up drug-modeling workflows while keeping scientific results traceable. This supports the company's long-term technology story, though the pending buyout now matters more for the share price.

    It shows the technology value underpinning the company being acquired.

  • 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.

    It gives the latest financial health picture behind the buyout.

  • 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.

Simulations Plus Licenses ADMET Predictor to FDA Cosmetics Regulatory Science Branch

Simulations Plus announced that the U.S. Food and Drug Administration's Cosmetics Regulatory Science Branch has licensed its ADMET Predictor software platform to support computational research for modern cosmetic safety assessment. The contract expands the use of Simulations Plus technology within the FDA and underscores the growing role of predictive modeling and mechanistic science in regulatory research. ADMET Predictor combines artificial intelligence and machine learning with high-throughput pharmacokinetic modeling and predictive ADMET and toxicity assessments, giving FDA researchers a unified computational framework to evaluate both potential exposure and intrinsic hazard. The development supports the FDA's ongoing research into New Approach Methodologies. The announcement builds on Simulations Plus' 2024 research collaboration with the International Collaboration on Cosmetics Safety to evaluate physiologically based kinetic modeling approaches for animal-free safety assessment of cosmetics and other non-pharmaceutical ingredients. Chief Executive Officer Shawn O'Connor said the FDA's adoption expands the company's relationship with one of the world's leading regulatory organizations and highlights the versatility of its technology beyond pharmaceutical research.
