Lhasa LIMITED

Lhasa LIMITED, a United Kingdom-based non-profit organization, licenses computational chemistry and chemical-safety software to federal agencies, primarily the Environmental Protection Agency and the Food and Drug Administration, operating as a prime vendor across full-and-open procurements with no set-aside participation.

Lhasa's federal footprint is narrow in scope and dollar volume. The organization holds 33 prime purchase orders totaling $872 thousand in combined potential value, with $667 thousand obligated across the portfolio (76% realization rate). Customer concentration splits between EPA and HHS-FDA: the FDA (5 awards, $485 thousand combined potential value) and the EPA's Office of Chemical Safety and Pollution Prevention (10 awards, $112 thousand combined potential value) account for 86% of the combined potential value by Lhasa's top-five customer ranking. The EPA's Office of Research and Development, Office of Land and Emergency Management, and the National Institutes of Health National Cancer Institute round out the active agency base. All awards are purchase orders issued in full-and-open competition without set-aside designation.

Lhasa's product portfolio centers on the Nexus suite: Derek Nexus (computational toxicity and chemical hazard assessment), Meteor Nexus (chemical-property prediction and environmental hazard evaluation), Sarah Nexus (structural alert identification), Vitic (predictive toxicology), and Zeneth (chemical structure analysis). Representative recent awards include a $120,880 purchase order from the FDA's Office of Cosmetics and Colors awarded July 31, 2026, for LHASA software and licenses extending through September 30, 2031; a $131,835 purchase order from the FDA awarded May 21, 2025, for the LHASA Knowledge Suite Nexus bundle covering Derek, Meteor, Vitic, Sarah, and Zeneth platforms; and a $43,953 purchase order from EPA's Office of Chemical Safety and Pollution Prevention awarded August 26, 2025, for subscription renewal of Derek Nexus, Meteor Nexus, and Sarah Nexus, running through August 25, 2028. These are classified under primary NAICS 541512 (Software Publishers, appearing in 20 awards) and PSC category "Information Technology Software" (17 awards).

Activity has fluctuated at low volume, with one award in 2022, one in 2023, one in 2024, three in 2025, and one in 2026 (July 31, 2026), totaling six awards across the most recent five years from a portfolio spanning two decades. The recompete cliff shows one award ($44 thousand combined potential value) reaching ultimate completion inside the next twenty-four months. Lhasa operates exclusively as a prime; the Service Contract Inventory dataset captures minimal federal services activity—2 records in FY2025 totaling 1.8 FTEs, both as named subcontractor, indicating that SCI-reportable service contracts do not form a material part of Lhasa's federal revenue model. The corporate structure includes a named foreign-owned for-profit subsidiary, Molecular Networks GMBH Computerchemie, which likely supplies underlying computational chemistry capabilities to the parent organization.
