Cal-Maine Foods, Inc.
Cal-Maine Foods, Inc. (CALM)
Overview
Cal-Maine Foods, Inc. is the largest producer and distributor of shell eggs in the United States, headquartered in Ridgeland, Mississippi and founded in 1957 by Fred R. Adams Jr. It is a mid-to-large-cap company in the packaged foods/agriculture industry, with fiscal 2026 (ended May 2026) net sales of roughly $2.9 billion and a market capitalization of about $3.4 billion, though both revenue and profit fell sharply year-over-year as egg prices normalized from the historic highs seen in fiscal 2025. The company operates as a single, vertically integrated segment covering shell egg and egg-product production, and has recently begun diversifying beyond eggs through the May 2026 acquisition of the Van's Foods frozen breakfast brand.
What They Do & How They Make Money
Cal-Maine makes money by producing, processing, marketing, and distributing shell eggs — plus a smaller line of liquid/frozen egg products and prepared foods — to national and regional grocery chains, club stores, foodservice distributors, and food manufacturers across 35 U.S. states and Puerto Rico. Its business is vertically integrated from feed to shelf: the company owns roughly 48.3 million egg-laying hens and 11.5 million pullets/breeders, produces about 1.9 of the 2.1 million tons of feed it needs annually in its own feed mills, and operates modern "in-line" processing facilities co-located with its farms for efficiency; roughly 88.6% of the shell eggs it sells are company-produced, with the remainder from contract producers. Revenue is split across conventional eggs (66.9% of fiscal 2025 sales, including branded and private-label product), specialty eggs (27.6%, covering cage-free, organic, free-range, and other higher-margin premium categories), and egg products/prepared foods (4.6%). Because shell eggs are a largely undifferentiated commodity, profitability is driven overwhelmingly by the market price of eggs — which is itself highly volatile due to supply shocks (notably avian influenza outbreaks that periodically cull large portions of the national laying flock) — rather than by brand differentiation or traditional pricing power. Customer concentration is high: Walmart (including Sam's Club) alone represented 33.6% of fiscal 2025 net sales, and the top three customers together accounted for 49.2%.
Competitors
The shell egg industry is large but fragmented, and Cal-Maine's 10-K notes that the ten largest producers together owned only about 54% of the industry's table-egg layer hens at the end of calendar 2024, implying no single dominant rival but many mid-sized competitors, including Rose Acre Farms, Versova Holdings, Hillandale Farms, Opal Foods, and Daybreak Foods, along with numerous smaller regional and co-operative egg producers. Competition centers on price, supply reliability, and service rather than brand loyalty, and the company also competes for shelf space and contracts against store-brand/private-label egg programs run directly by large grocery chains.
Competitive Position
Cal-Maine's primary competitive advantage is sheer scale and vertical integration: as the largest U.S. shell egg producer, it captures cost efficiencies in feed production, processing, and logistics that smaller regional competitors cannot easily match, and this scale has let it serve the largest national retailers (notably Walmart) as a primary supplier. However, the business remains fundamentally a commodity producer with very limited pricing power of its own — a dynamic starkly illustrated by fiscal 2026, when net sales fell roughly 32% and net income collapsed about 74% as egg prices normalized from 2024–2025's avian-flu-driven spike, with the company posting a fourth-quarter loss versus a large prior-year profit. The company also faces meaningful legal and reputational risk: in June 2026 it reached a settlement with the U.S. Department of Justice and 17 state attorneys general over allegations that it secretly coordinated with competitors to inflate egg prices between June 2022 and March 2025. Structural risks going forward include continued exposure to avian influenza outbreaks, extreme customer concentration (loss of Walmart as a customer would be highly damaging), and the inherently cyclical, low-margin nature of commodity egg production. The May 2026 acquisition of the Van's Foods frozen breakfast brand signals a deliberate strategic push to diversify revenue into higher-margin, less commodity-driven prepared foods, a shift that will likely determine how durable Cal-Maine's earnings power proves to be over the next cycle.
