Biotech companies in Maryland: the I-270 corridor, Frederick's plants and the federal labs

This report is for job seekers, investors, partners and suppliers looking at biotech companies in Maryland. It's a state view, so it covers Baltimore as well as the I-270 corridor from Bethesda and Rockville through Gaithersburg and Germantown to Frederick.

How many biotech companies are in Maryland

County Business Patterns (CBP) 2023, Maryland, NAICS 541714 (biotech research and development) and 325414 (biological product manufacturing):

The two codes split into many small labs and a few very large plants:

The plants average about 256 employees each (our calculation), and three of the ten have 500 to 999 employees. As with all CBP data, these are payroll establishments rather than companies, and sole proprietors aren't included.

By size and county

The combined size table isn't published because most manufacturing cells are suppressed. The R&D code shows the shape of the lab base: 126 labs have 1 to 4 employees, 53 have 5 to 9, 29 have 10 to 19, 37 have 20 to 49, 22 have 50 to 99, 8 have 100 to 249 and 6 have 250 to 499; the largest classes are withheld.

Those figures exist but carry the Census Bureau's high-noise flag, meaning its confidentiality adjustments changed them by at least 5%. Montgomery County is the research center; Frederick is the manufacturing center.

What the codes leave out

Federal labs are the biggest gap. NIH's own intramural research in Bethesda, FDA in Silver Spring and the labs at Fort Detrick are government, not industry, so they aren't in CBP. Contract research organizations and data firms (coded in testing, consulting or computing), drug plants (325412) and corporate headquarters are also outside these codes. Maryland's Department of Commerce says its Maryland Life Sciences Directory lists more than 1,800 life sciences companies, a definition that includes medical technology and digital health.

The listed companies

SEC EDGAR lists 23 listed companies with a Maryland business address in SIC 2834 (pharmaceutical preparations, 18), 2836 (biological products, 4) and 8731 (commercial research, 1). From their latest filings:

Employees as of 31 December 2025, blank where we didn't take a figure. Champions Oncology has a Baltimore address in EDGAR but gives Hackensack, New Jersey, in its 10-K, so it's left out.

The top four are commercial companies with steady procurement. Below them, REGENXBIO spent more on R&D than it earned in revenue and MacroGenics about as much, and the rest are smaller companies with fewer than 110 employees where stated.

NIH money, and who gets it

NIH RePORTER shows $2.17 billion of NIH awards to 129 Maryland organizations in fiscal 2025 (October 2024 to September 2025), across 2,438 projects. That excludes NIH's own intramural spending.

For-profit organizations received 341 awards worth $912.5 million, far more than Massachusetts' $193.9 million, because several large NIH research contractors are based here, led by Leidos Biomedical Research, Westat and Emmes. Only 82 of those were small-business (SBIR or STTR) grants, worth $63.9 million to 62 companies; that's the figure to use for startup activity.

Where biologics are made

Maryland's biologics makers appear in two FDA files: the cell and tissue registry, and the drug establishment registry used by other biologics manufacturers. Plants making only trial material don't have to register.

• Drug establishment registry: 82 Maryland registrations, 65 with manufacturing operations. Registrants include Kite Pharma and AstraZeneca in Frederick, Novavax in Gaithersburg, REGENXBIO and Bora Biologics in Rockville, Precigen and uBriGene in Germantown, United Therapeutics in Silver Spring and Beltsville, Xcellon Biologics in Beltsville, and Catalent and Syngene in the Baltimore area.
• Cell and tissue registry: six Maryland establishments are registered for blood stem cell or immune cell products: the NIH Clinical Center and a hematology and oncology clinic in Bethesda, Johns Hopkins Hospital, University of Maryland Medical Center (two registrations) and Miltenyi Biotec in Gaithersburg.

Frederick County's economic development office describes Kite's site there as a 279,000-square-foot biologics manufacturing facility, consistent with the county's 1,890 biologics plant employees.

Where to look

1. Maryland Life Sciences Directory, from the state Department of Commerce, for company names by sector.
2. Maryland Tech Council, the state's technology and life sciences association, for its member directory and job board.
3. Frederick County Office of Economic Development for the manufacturing employers around Fort Detrick.
4. NIH RePORTER for Johns Hopkins and University of Maryland investigators whose work is moving toward a company.

Selling to Maryland biotech

Worked example: a biomanufacturing training provider

Illustrative example. The provider, course prices and take-up rates are invented; the employee counts come from CBP 2023.

Monocacy Skills (monocacyskills.example) runs GMP and aseptic technique training for plant staff.

1. Size the audience. Maryland's 10 biologics plants employ 2,563 people, 1,890 of them in Frederick County.
2. Do the arithmetic. If 15% of plant staff need refresher or new-hire training each year (about 385 people) and Monocacy trains a third at $1,200 a seat, that's about 128 seats and $154,000 a year.
3. Add the labs. The 22 R&D labs with 50 to 99 employees are moving toward clinical supply and will need GMP training next.

Matching each plant to its training or quality lead is the slow part. Bebop matches each site to likely contacts and drafts a first message.
