About Greystone Logistics, Inc.
Greystone Logistics, Inc. (ticker: GLGI) is a U.S.-listed company on the NASDAQ, operating in a niche segment at the intersection of industrial manufacturing, logistics, and circular-economy materials. The company was originally incorporated in 1969 under a different name and went through several corporate name changes before adopting the Greystone Logistics name in 2005. A key inflection point in its modern history came in 1997, when it acquired Plastic Pallet Production, Inc., and the business has since been primarily focused on plastic pallet manufacturing.
Today, Greystone’s core business is the manufacture and sale of plastic pallets, together with pelletized recycled plastic resin. Recent SEC filings indicate that the company operates through two wholly owned subsidiaries, Greystone Manufacturing, L.L.C. and Plastic Pallet Production, Inc. Its principal product remains recycled-resin plastic pallets, which positions Greystone in a specialized industrial submarket where durability, hygiene, consistent sizing, and reusability are commercially important. In practical terms, the company serves supply-chain users that need handling platforms with a longer service life and a lower dependence on wood-based pallets.

From a competitive standpoint, Greystone is a focused niche player rather than a broad logistics platform. Its investment case is tied to industrial demand for pallet solutions, customer adoption of plastic versus wooden pallets, and the economics of recycled materials. The company’s manufacturing footprint is vertically integrated, and management has disclosed in recent filings that in-house injection-molding capacity is approximately 225,000 pallets per month, or 2.7 million per year, although actual output varies with product mix, machine downtime, and customer-specific specifications. The company has also disclosed an employee base of roughly 190 full-time employees, supplemented by temporary workers as needed.
Greystone is headquartered in Tulsa, Oklahoma, United States, with its principal business address referenced in SEC filings at 1613 East 15th Street, Tulsa, Oklahoma 74120. That U.S. location matters for investors because it underscores the company’s domestic manufacturing base and its primary exposure to the North American market. For French, Belgian, and Swiss investors, GLGI is best understood as a specialized small-cap industrial name with a clear operational focus rather than a diversified logistics conglomerate.
Recent developments suggest a mixed but highly company-specific operating backdrop. The latest annual report shows a year-over-year revenue decline, driven largely by lower demand from one significant customer, partially offset by stronger demand from another major customer. That pattern highlights the company’s customer concentration risk and the sensitivity of results to order timing and end-market volumes. At the same time, recent Form 4 insider transaction filings have shown buying activity by company insiders, including executives and directors, which may signal internal confidence, though it should not be read as a stand-alone investment thesis.
Overall, Greystone Logistics remains a specialized U.S. industrial manufacturer on the NASDAQ, with a narrow product set, a recycled-materials angle, and performance that is closely linked to customer demand, manufacturing efficiency, and the adoption of plastic pallets in logistics chains.
