Parsons Corporation

Overview

Parsons Corporation is a U.S. defense and infrastructure contractor founded in 1944 as The Ralph M. Parsons Company (IPOX; SEC). Its path to the public markets was unusual twice over: first its own employees bought the entire company in 1984 — one of the largest employee-stock-ownership takeovers of a public company ever — and then, 35 years later, they took it public again on the New York Stock Exchange under the ticker PSN (Washington Technology).

The workforce buys the company

Parsons was an early ESOP adopter, launching its employee stock ownership plan in 1978 as a way to attract and retain high-end technical talent at what was then a seven-decade-old engineering and government services contractor (Washington Technology). In 1984 the plan’s participants — the workforce itself — acquired all of the company after 15 years of it being publicly traded, in what the trade press described as one of the largest-ever takeovers of a public company by ESOP shareholders (Washington Technology). SEC filings trace the plan’s lineage further back: it was originally effective December 28, 1974, under the name The Ralph M. Parsons Company Employee Stock Ownership and Retirement Plan, and became The Parsons Corporation Employee Stock Ownership Plan on January 1, 1984 (SEC). One of the employees behind the 1984 buyout was Chuck Harrington, who would later lead the company as CEO (Washington Technology).

Back to the NYSE

On May 8, 2019, Parsons returned to the public markets, debuting on the NYSE under ticker PSN and raising nearly $500 million at $27 per share — the midpoint of its anticipated range (Washington Technology). The offering covered 18.5 million shares, with underwriters holding a 30-day option on 2.77 million more (Washington Technology). Wall Street liked the debut: shares closed up 11.41% at $30.08 on volume of 14.7 million shares (Washington Technology). The offering formally closed on May 10, 2019, per the company’s SEC 8-K (SEC). IPO proceeds were earmarked for paying down debt and investing in cybersecurity, intelligence, space, defense and “Smart Cities” infrastructure — plus a $52.1 million dividend to ESOP participants, who still held 81% of the company’s shares (Washington Technology).

At the time of the IPO, Parsons posted $3.5 billion in annual revenue, with federal work representing 41.5% ($1.5 billion) of it (Washington Technology). Harrington pointed to nearly 70 years of missile-defense work and growing investments in artificial intelligence and machine learning as the company’s focus areas (Washington Technology).

The Chantilly defense contractor

Parsons moved its headquarters from Centreville to Chantilly, Virginia, in 2023, as reflected in SEC filings from August to October of that year (Virginia Business). The company reported $4.2 billion in 2022 revenue and employs more than 17,000 people (Virginia Business). In January 2026 it landed a $250 million classified contract award (Virginia Business).
