Facility will manufacture injectable medicines, including retatrutide
Site will create 850 high-wage jobs and 2,000 construction jobs
INDIANAPOLIS, Nov. 12, 2026 /PRNewswire/ -- Eli Lilly and Company (NYSE: LLY) today broke ground on a $3.5 billion manufacturing facility in Pennsylvania's Lehigh Valley. The site is one of 10 new U.S. manufacturing sites announced since 2020 and one of four among them dedicated to injectable medicines and devices. Part of the company's $50 billion push to expand medicine production in the U.S., the Lehigh Valley site will add capacity for the next generation of obesity treatments, including retatrutide, a first-in-class investigational GIP, GLP-1 and glucagon triple hormone receptor agonist.
David A. Ricks, Lilly Chair and CEO: "Obesity is one of the biggest health challenges of our time, and the science to treat it is moving quickly. Retatrutide is one of several next-generation medicines we're developing that could help millions more people living with obesity, type 2 diabetes, or both. This $3.5 billion investment means we'll be able to make these medicines in Pennsylvania for people here at home and around the world."
Supporting community in the Lehigh Valley
As part of its community commitment, Lilly and the Upper Macungie Township Community Fund are working together on an anticipated new community initiative at the Upper Macungie Community Center. Lilly will provide up to $1 million over five years to the Upper Macungie Township Community Fund to support an initiative to develop a new quality-of-life program for Lehigh Valley families, with a focus on nutrition and healthy living, fresh food access, health resources, and community programming. Good health starts with strong communities, and as the Lehigh Valley becomes one of Lilly's newest sites, the company is proud to support the families and organizations working to make the area stronger.
Creating careers in advanced manufacturing
Lilly is currently hiring in the Lehigh Valley and expects the new facility to create 850 high-wage jobs like engineers, scientists, operations personnel, and lab technicians – along with approximately 2,000 construction jobs as the site is built and brought online.

Pennsylvania Governor Josh Shapiro: "Today marks another historic milestone in Pennsylvania's thriving life sciences sector and reinforces my Administration's commitment to advancing innovation, strengthening the economy, and creating good-paying jobs across the Commonwealth. We secured this historic, life-changing investment thanks to Pennsylvania's world-class workforce, research institutions, infrastructure, and resources, and my Administration will continue working hard to ensure Pennsylvania remains a place where groundbreaking discoveries can translate into meaningful economic opportunities and results for patients and families."
By pairing a highly skilled workforce with advanced technologies and specialized manufacturing, the Lehigh Valley site will help support a reliable supply of safe, high-quality medicines. It will use state-of-the-art technologies, including machine learning, AI, digitally integrated systems and advanced data analytics, to drive right-first-time execution, with digital automation embedded throughout the site to streamline operations.
Edgardo Hernandez, Executive Vice President and President of Lilly Manufacturing Operations: "Before a dose of medicine leaves one of our sites, each production run goes through more than 5,000 documented steps and each unit is imaged and inspected more than 70 times to check for defects. These are just a few examples of the quality control we take to protect our patients. Lehigh Valley will build on that discipline with next-generation automation and digital systems, so we can do things right the first time and help patients count on their medicines for years to come, made in Pennsylvania."
The facility will be built and operated to the highest standards for safety, quality and environmental stewardship, and Lilly is committed to being a good neighbor in Lehigh Valley and across Pennsylvania. The site is targeting a Leadership in Energy and Environmental Design (LEED) Gold certification, demonstrating Lilly's focus on sustainable performance as it expands advanced manufacturing in the U.S.
The Lehigh Valley site, located in Fogelsville, Pennsylvania, is expected to be operational by 2031.
Lilly has announced 10 U.S. sites since 2020:
- Five will produce API:
- Richmond, Virginia; Huntsville, Alabama; Houston, Texas; and two sites in Lebanon, Indiana – Lebanon API and Lilly Medicine Foundry, which will also focus on new production methods and making medicines for clinical trials
- Four will make injectable medicines and manufacture devices:
- Research Triangle Park and Concord, North Carolina; Kenosha, Wisconsin; and Lehigh Valley, Pennsylvania
- One will make genetic medicines in Lebanon, Indiana; Lebanon Advanced Therapies

Retatrutide is an investigational, once-weekly, triple hormone receptor agonist. Retatrutide is a single molecule that activates the body's receptors for glucose-dependent insulinotropic polypeptide (GIP), glucagon-like peptide-1 (GLP-1), and glucagon. Lilly is studying retatrutide in several Phase 3 clinical trials to evaluate its potential efficacy and safety in obesity and overweight with at least one weight-related medical problem, type 2 diabetes, knee osteoarthritis pain, moderate-to-severe obstructive sleep apnea, chronic low back pain, cardiovascular outcomes, and metabolic dysfunction-associated steatotic liver disease. Retatrutide is an investigational molecule that cannot be legally sold or marketed for human use.
