Investing.com -- Eli Lilly and Company announced Wednesday it will reduce its remaining investment in a German production facility by half, cutting $1.5 billion from its spending plans and eliminating a substantial portion of 1,000 planned jobs.

The Indianapolis-based pharmaceutical company cited proposed healthcare reforms in Germany that aim to lower drug prices as the reason for scaling back the $2.5 billion project in Alzey. Interior work at the site continues and 300 employees have been hired, ensuring the facility will become operational.

Lilly said the decision to expand remaining capacity has been suspended and will depend on whether stable and predictable economic conditions return to Germany. The company described the healthcare measures as making investments in jobs and production facilities impossible to calculate, calling it a breach of trust.

The healthcare proposals are scheduled for a vote in Germany's parliament this summer. The reforms seek to reduce pharmaceutical costs by lowering drug prices in the country.

BioNTech SE, Germany's largest biotech firm, also said future investments in the country will partly depend on whether policymakers create an attractive framework for pharmaceutical companies.

Boehringer Ingelheim GmbH previously canceled investments worth €900 million at German sites due to unpredictability in the country's pharmaceutical sector.
