Score History
Timeline events are AI-curated from public reporting. Score trajectory is derived from documented events.
Jim Sinegal and Jeffrey Brotman open the first Costco warehouse in Seattle, built on low markups, a paid membership and above-market pay. The $1.50 hot dog combo arrives in 1985, the year Costco lists on NASDAQ. With no advertising, a small footprint and profits driven by membership fees, extraction pressure is minimal.
Costco merges with Price Club to form PriceCostco, the dominant U.S. warehouse club. The 1995 launch of Kirkland Signature gives it leverage over national brands, which it used in 2009 by refusing to restock Coca-Cola until it got better pricing for members. Fees rise modestly in 2000 and 2006, the $4.99 rotisserie chicken debuts, and a 2004 gender-discrimination class action over promotions begins, while Sinegal's low-margin, well-paid model holds.
Craig Jelinek succeeds co-founder Jim Sinegal as CEO, and within the year Costco pays a $7 per-share special dividend worth about $3.0 billion. The Tiffany counterfeit-ring suit (2013), the $8 million gender-discrimination settlement (2014), supplier controversies over eggs and Thai shrimp (2015), the $11.75 million DOJ pharmacy settlement (2017) and Ontario's $7.2 million kickback fine (2019) mark a run of legal and compliance lapses. Costco moves to an exclusive Citi Visa co-brand in 2016, launches CostcoGrocery and raises fees to $60 in 2017, and keeps wages high.
Costco opens its $450 million Lincoln Premium Poultry complex in Nebraska, taking direct control of chicken production and the animal-welfare and food-safety exposure that comes with it. Through the pandemic years it raises starting pay to $16 (2021) and pays a $10 per-share special dividend ($4.4 billion) in 2020, while the Teamsters win a first national master agreement and a new Virginia unit. In late 2023, class actions allege its pharmacy website shared health data with Meta through a tracking pixel.
Ron Vachris, who started as a forklift driver, becomes CEO. His tenure tightens and monetizes the membership: entrance card scanners and the first fee increase in seven years (2024), Executive-only early hours (2025) and a retail media business, rebranded Costco Velocity in 2026, that sells suppliers ads targeted with member purchase data. Tariff-era price increases, a $14 million settlement over urgency-laden promotional emails and suits over Kirkland labels and chicken safety sit alongside pay raised above $30 an hour for many workers after a Teamsters strike threat, a firm defense of its DEI programs and a pledge to return tariff refunds to members through lower prices.
Alternatives
Warehouse club with a $60/year Club membership ($120 for Club+) since January 2025, slightly below Costco's $65. It accepts manufacturer coupons on top of its own, and its clubs are smaller than Costco's warehouses. Easy switch if one is nearby; the catch is a much narrower footprint than Costco's, mostly along the East Coast and in Michigan.
Walmart-owned warehouse club with a $60/year Club membership (vs. Costco's $65) and a $120 Plus tier; Sam's raised both by $10 in May 2026. Easy switch: similar bulk categories and pricing, with Member's Mark as its private label in place of Kirkland Signature. Its Scan & Go app lets members scan and pay on their phone and skip the checkout line, while Costco is still testing pre-scan checkout. The catch: it is part of Walmart, and membership auto-renews unless you cancel at least 24 hours before the renewal date.

Dimension History
Timeline (54 events)
First Costco warehouse opens in Seattle
Jim Sinegal and Jeffrey Brotman open the first Costco warehouse in Seattle, Washington. Sinegal, who learned the warehouse club model working for Sol Price at FedMart and Price Club, establishes Costco with a $25 annual membership fee and a philosophy of capping markups at 14% on branded goods. The company opens two more locations in Portland and Spokane by year's end.
Costco introduces $1.50 hot dog combo
Costco begins selling its hot-dog-and-soda combo for $1.50, a price point that will remain unchanged for over 40 years. Co-founder Jim Sinegal famously told a later CEO who suggested raising the price, 'If you raise the effing hot dog, I will kill you.' The loss leader becomes an iconic symbol of Costco's commitment to value over margin extraction.
Costco goes public on NASDAQ at $10 per share
Costco conducts its IPO on NASDAQ at $10 per share ($1.67 split-adjusted), overseeing 17 warehouses and ending fiscal 1985 with 115,000 members. Costco would go on to become the first company to grow from zero to $3 billion in sales in fewer than six years. The IPO provides growth capital while Sinegal's continued leadership prevents the typical post-IPO pivot toward shareholder extraction.
Costco merges with Price Club to form PriceCostco
Costco and Price Club merge to form PriceCostco, creating a chain of 206 warehouses with $16 billion in annual sales and becoming the largest warehouse club in the United States. Price Club had rejected a competing merger offer from Walmart's Sam's Club. Disagreements between Robert Price and Jim Sinegal over company direction lead to Price's departure in 1994, when Price Enterprises was spun off from the company; it later launched PriceSmart.
Kirkland Signature private label launched
Costco launches the Kirkland Signature brand, which would soon appear on everything from diapers to tires. Co-founder Jim Sinegal consolidates the company's roughly 30 previous private labels under a single brand, named after Kirkland, Washington, where Costco was then headquartered. The strategy requires Kirkland products to be at least equal quality to national brand leaders while priced about 15-20% below, creating competitive pressure on suppliers to manufacture their own competition or lose Costco's volume.
Membership fee increased from $40 to $45
Costco raises its Gold Star membership fee from $40 to $45, a 13% increase. This is part of the company's pattern of infrequent, modest fee increases roughly every 5-7 years. The increase funds continued warehouse expansion, with Costco operating more than 330 locations worldwide by this point.
Costco introduces $4.99 rotisserie chicken
Costco debuts its rotisserie chicken at $4.99, a price it has kept for more than two decades apart from a brief $1 increase during the 2008 financial crisis. The chicken becomes a loss leader that drives foot traffic and additional purchases. CFO Richard Galanti acknowledged in 2015 that holding the price cost Costco millions in margin, placing chickens at the back of stores near wines and side dishes to maximize incremental spending.
Gender discrimination class action filed against Costco
Shirley Ellis files a class action lawsuit (Ellis v. Costco) alleging that Costco systematically denied women promotions to management positions. The class eventually grows to over 1,250 current and former female employees. Despite Costco's reputation as an ethical employer, the lawsuit reveals that the company lacked formal posting systems for management positions, allowing subjective promotion decisions that disadvantaged women.
Sinegal defends paying workers 42% above Sam's Club
In a widely cited New York Times profile, CEO Jim Sinegal defends Costco's practice of paying average wages of $17/hour, 42% higher than rival Sam's Club. Sinegal takes home a $350,000 salary, far below the typical Fortune 500 CEO, and tells the Times, 'Having an individual who is making 100 or 200 or 300 times more than the average person working on the floor is wrong.' Wall Street analysts criticize the approach as overly generous to employees.
Membership fee increased from $45 to $50
Costco raises Gold Star membership from $45 to $50 effective May 1, 2006, an 11% increase and the first fee hike in six years, after opening 143 new locations since 2000. Executive membership stays at $100 a year, with its 2% reward still capped at $500.
Costco stops restocking Coca-Cola over pricing
Costco stopped reordering Coca-Cola products nationwide, posting 'Price Alert!' notices that Coca-Cola had not provided pricing competitive enough to pass value to members. The standoff was resolved within weeks and showed Costco using its scale to press suppliers for lower prices on members' behalf.
Membership fee increased from $50 to $55; Executive to $110
Costco raises Gold Star membership from $50 to $55 and Executive membership from $100 to $110, both 10% increases. The Executive tier, whose 2% reward cap rises from $500 to $750 annually, deepens behavioral lock-in by rewarding concentrated spending at Costco over competitors.
Craig Jelinek succeeds Jim Sinegal as CEO
W. Craig Jelinek becomes Costco's second CEO on January 1, 2012, succeeding co-founder Jim Sinegal, who retires after leading the company since 1983. Jelinek, a Costco veteran since 1984, maintains Sinegal's low-margin philosophy and worker-friendly pay practices. Costco pays its first special dividend of $7 per share the same year, reflecting the company's growing cash generation.
Costco declares $7 special dividend worth $3 billion
Costco declared a $7.00-per-share special dividend, about $3.0 billion, paid December 18, 2012 ahead of expected dividend-tax increases; the CFO cited its balance sheet and 'favorable access to the credit markets'. It was the first of the special dividends that recur through 2024.
Tiffany sues Costco over counterfeit ring labels
Tiffany & Co. sues Costco on Valentine's Day for selling generic diamond engagement rings under display signs reading 'Tiffany.' Tiffany wins a $21 million judgment in 2017 after a jury trial, but the Second Circuit throws it out in August 2020, finding reasonable consumers might not be confused. The case settles in July 2021 on undisclosed terms. The incident highlights Costco's sometimes loose approach to product labeling.
Costco settles gender discrimination class action for $8 million
A federal court approves an $8 million settlement in Ellis v. Costco, the class action alleging systemic denial of promotions to women. The class includes over 1,250 current and former female employees. Beyond monetary relief, Costco agrees to implement a formal posting system for assistant general manager and general manager positions and work with an independent consultant to analyze its promotion practices.
Humane Society exposes Costco egg supplier conditions
The Humane Society of the United States releases undercover footage from Hillandale Farms, a Costco egg supplier, showing hens in cages so small they cannot spread their wings, forced to share space with mummified dead birds. The HSUS files complaints with the FDA and FTC. Actor Ryan Gosling publicly criticizes Costco. The company gradually responds by transitioning to cage-free eggs, reaching 97% cage-free by September 2022.
Costco sued over Thai shrimp linked to slave labor
A California consumer files a class action alleging Costco knowingly sold farmed prawns from Thailand that were fed with fish products harvested using slave labor on 'ghost ships,' where workers were reportedly kept in cages. The case is dismissed in January 2017 because plaintiffs could not prove Costco had a packaging disclosure obligation, but the lawsuit draws attention to supply chain oversight gaps at the company.
Costco switches to exclusive Citi Visa co-brand card
Costco ended its 17-year exclusive relationship with American Express and began accepting only Visa credit cards in U.S. warehouses, with Citi issuing the new Costco Anywhere Visa to about 11.9 million former AmEx co-brand holders. An analyst estimated Costco would save more than $100 million a year in card-acceptance costs.
Costco pays $11.75M to settle pharmacy control violations
Costco pays $11.75 million to settle DOJ allegations that its pharmacies violated the Controlled Substances Act by improperly filling prescriptions between 2012 and 2015. Violations include filling incomplete prescriptions, lacking valid DEA numbers, and failing to maintain accurate records for controlled substances. Costco purchases a new pharmacy management system at a budgeted five-year cost of $127 million and agrees to allow unannounced DEA inspections for three years.
Membership fee increased from $55 to $60; Executive to $120
Costco raises Gold Star membership from $55 to $60 and Executive membership from $110 to $120, continuing its pattern of 9-10% increases every 5-7 years. The fee will remain at this level for seven years, the longest gap between increases in the company's history, spanning the entire COVID-19 pandemic and a period of significant retail inflation.
Costco launches CostcoGrocery two-day delivery
Costco launches CostcoGrocery, offering two-day delivery on approximately 500 nonperishable items, marking a significant e-commerce expansion after being slow to embrace online retail. The move comes shortly after Amazon's acquisition of Whole Foods raises concerns that Costco is vulnerable to digital competition. E-commerce sales grow 28.5% year over year to $1.5 billion in the quarter ended February 2018, though e-commerce remains a small fraction of total revenue.
Ninth Circuit affirms dismissal of Thai shrimp suit
The Ninth Circuit upheld the dismissal of the 2015 class action alleging Costco sold Thai prawns produced with slave labor, finding the plaintiffs had not pled reliance on Costco's supply-chain representations. The ruling ended the case without addressing the underlying labor abuses.
Ontario fines Costco $7.2M for pharmacy kickbacks
The Ontario government fines Costco more than $7.2 million after determining that Costco's Ontario pharmacies received $7.25 million from generic drug makers for 'advertising services' that violated the ban on rebates; the allegations were first raised by a Ranbaxy salesperson. Two Costco pharmacy directors, Joseph Hanna and Lawrence Varga, had earlier pleaded guilty to professional misconduct for soliciting over $1.2 million from Ranbaxy. Each pharmacist was fined $20,000 and ordered to pay $30,000 in costs.
First China store closes early due to overwhelming crowds
Costco opens its first mainland China store in Shanghai's Minhang district, drawing such massive crowds that the store must close early on opening day due to safety concerns. Customers face three-hour waits to park and two-hour checkout lines. Local police help manage crowds, and the next day Costco limits entry to 2,000 shoppers at a time. The event signals Costco's brand appeal in new international markets.
Lincoln Premium Poultry opens $450M chicken complex
Costco's vertically integrated poultry operation, Lincoln Premium Poultry, opens in Fremont, Nebraska, at a cost of $450 million. The facility was processing about 1 million chickens per week by early 2020, with plans to exceed 2 million, supplying Costco's $4.99 rotisserie chickens and Kirkland Signature raw chicken products. The operation contracts with close to 80 growers and employed more than 1,000 workers by March 2020. Vertical integration secures supply and pricing but exposes Costco to direct animal welfare liability for the first time.
Costco declares $10 special dividend
Costco declared a $10-per-share special dividend, about $4.4 billion funded from existing cash, its fourth special dividend in eight years, paid December 11, 2020.
Jelinek backs higher wages before Senate, lifts floor to $16
Testifying before the Senate Budget Committee as Congress weighed a $15 federal minimum wage, CEO Craig Jelinek said Costco would raise its starting wage to $16 an hour, up from $15 set in 2019, and that more than half of its U.S. hourly workers earned above $25. He said good wages were a competitive advantage, 'not altruism'.
Shareholders sue Costco over chicken welfare violations
Legal Impact for Chickens files a shareholder derivative lawsuit (Smith v. Vachris) in King County Superior Court alleging that Costco executives are causing the company to violate Nebraska and Iowa livestock neglect laws. An undercover 2021 investigation revealed chickens bred to grow so fast many cannot stand, with disabled birds unable to reach food or water. The court dismisses in March 2023, but shareholders file a formal demand on the board in July 2023.
Suits allege Costco shared pharmacy data with Meta
A proposed class action filed in federal court in Seattle alleges Costco embedded Meta's tracking pixel in the pharmacy pages of its website, sending prescription, treatment and insurance details to Meta without consent. Five such suits were filed by the end of October 2023; in November 2024 the court largely denied Costco's motion to dismiss, and the Washington Attorney General issued related civil investigative demands in 2024.
Norfolk, Virginia Costco workers unionize with Teamsters
Workers at a Costco in Norfolk, Virginia voted to join Teamsters Local 822, the union's first organizing win at Costco in two decades. The Teamsters, who ratified a first national master agreement with Costco in 2022, represent about 18,000 of Costco's roughly 208,000 U.S. employees.
Ron Vachris becomes CEO, rising from forklift driver
Ron Vachris, who began his Costco career as a forklift driver over 40 years ago, officially becomes the company's third CEO on January 1, 2024, succeeding Craig Jelinek. The succession continues Costco's tradition of promoting from within and maintaining cultural continuity. Jelinek stays through April to assist the transition and continues serving on the board.
Costco pays record $15 per share special dividend
Costco pays its largest-ever special dividend of $15 per share, distributing $6.7 billion to shareholders. This is the company's fifth special dividend, following similar payouts in 2012 ($7), 2015 ($5), 2017 ($7), and 2020 ($10). The payouts reflect Costco's strong cash generation.
Costco builds ad business on member purchase data
Costco disclosed it was building a retail media network using its 74.5 million member households' purchase histories to target ads on and off its website, led by an AVP of retail media hired in September 2023. Because membership is required to shop, Costco can tie in-store and online purchases to households for targeting and measurement.
Class action alleges undisclosed online price markups
A class action lawsuit alleges Costco charges higher prices on Costco.com than for identical items in warehouses without adequate disclosure, arguing its notice that an item 'may be available in your local warehouse for a lower' price does not reveal the online markup. Plaintiff Annie Song reports paying $33.49 online for Charmin toilet paper available for $4 less in-store. In December 2024 a separate proposed class action filed in Canada's Federal Court made a similar online-versus-in-store pricing allegation against Costco Wholesale Canada (Global News). The case highlights pricing opacity as Costco's e-commerce channel grows.
Costco deploys card-scanning entrance enforcement
Costco announces it will deploy membership card scanners at warehouse entrances over the coming months to crack down on membership sharing. In earlier tests, the scanners displayed the member's photo on file for employee verification. The enforcement measure tightens the membership wall and increases data collection, capturing visit frequency and linking physical presence to member profiles.
First membership fee increase in seven years
Costco raises Gold Star membership from $60 to $65 and Executive membership from $120 to $130, an approximately 8% increase and the first since June 2017. The seven-year gap is the longest in company history. Measured in blue-collar work time, the 2024 fee is 21% cheaper than the original $25 fee in 1983 (Human Progress). The 92% U.S. renewal rate remains steady after the increase.
85% of Costco Teamsters vote to authorize strike
18,000 Teamster-represented Costco workers vote by an 85% margin to authorize a strike ahead of their national master agreement's January 31 expiration. The Teamsters cite Costco's record $254 billion in annual revenue and $7.4 billion in net profits (up 135% since 2018), stating 'record profits demand record contracts.' The union demands increased seniority pay, paid family leave, and safeguards against surveillance.
Shareholders reject anti-DEI proposal by 98% margin
At Costco's annual meeting, more than 98% of shareholders vote against a proposal from the National Center for Public Policy Research asking the company to evaluate risks of maintaining diversity programs. Costco's board unanimously recommends rejection, stating DEI efforts 'follow our code of ethics' and help bring 'creativity and originality' to merchandise. The vote stands in sharp contrast to competitors like Target, Walmart, and Amazon scaling back their diversity commitments.
19 state attorneys general pressure Costco to drop DEI
Nineteen Republican state attorneys general, co-led by Kansas AG Kris Kobach and Iowa AG Brenna Bird, send a letter to CEO Ron Vachris urging Costco to 'end all unlawful discrimination imposed by the company' through its DEI policies. They demand Costco drop its programs within 30 days or explain its refusal. Costco does not comply, and Washington state's AG publicly supports the company's position.
Costco raises wages above $30/hour, averting strike
As the Teamsters' strike deadline approaches, Costco announces it is raising pay above $30 an hour for many workers: top-of-scale clerks and assistants go to $30.20 an hour in March, with another $1 each year after that, and entry-level pay rises 50 cents to $20. CEO Ron Vachris's memo also adds vacation time for first-year employees. Costco and the Teamsters reach a tentative agreement early on February 1, averting the strike.
Executive-only early shopping hours take effect
Costco opened U.S. warehouses at 9am exclusively for $130 Executive members (9-10am weekdays and Sundays, 9-9:30am Saturdays) and added a $10 monthly delivery credit for the tier. Warehouses that had opened at 9am for all members moved general access to 10am, and Gold Star members objected to being shut out; Executive members were more than 47% of paid memberships but 73.1% of sales.
Costco pharmacies sell Ozempic and Wegovy for $499
Novo Nordisk announced that Costco's U.S. pharmacies would sell a month's supply of Ozempic or Wegovy for $499 out of pocket, against list prices of roughly $1,300 and $1,600, with an extra 2% discount for Executive members and Costco Citi Visa holders. It matched the drugmaker's direct-to-consumer price.
Costco sues Trump administration over IEEPA tariffs
Costco files suit at the U.S. Court of International Trade challenging President Trump's global tariffs imposed under the International Emergency Economic Powers Act, seeking a 'full refund' of all duties paid. Costco argues Congress, not the president, holds tariff authority under IEEPA. Costco filed the suit quietly on the Friday after Thanksgiving to preserve its place in line for refunds while the Supreme Court weighed the tariffs; importers had paid nearly $90 billion in IEEPA duties through late September 2025. In early December Costco's case was consolidated into the lead case AGS Company Automotive Solutions v. U.S. Customs and Border Protection, which lists more than 75 consolidated plaintiffs including Revlon and Kawasaki (Tax Notes).
Costco pulls 'no preservatives' rotisserie chicken claims
After two California shoppers filed a proposed nationwide class action on January 22, 2026 alleging its Kirkland Signature rotisserie chicken contains sodium phosphate and carrageenan despite 'no preservatives' claims, Costco removed the preservative statements from warehouse signs and online listings. Costco said the additives aid moisture and texture and are approved by regulators; the plaintiffs' lawyer said the quick removal confirmed the claim was inaccurate.
Class action alleges chronic salmonella problems in Costco chicken
A proposed class action filed in federal court in Seattle alleges Costco's Lincoln Premium Poultry plant in Nebraska received the USDA's worst salmonella rating (Category 3) in 92% of reporting periods since 2019 and failed every monthly test from late 2023 through mid-2025. The suit ties the problem to cost decisions that keep the rotisserie chicken at $4.99 and seeks damages for chicken buyers since 2019.
Costco pledges to return tariff refunds through lower prices
Two weeks after the Supreme Court struck down the IEEPA tariffs on February 20, 2026, CEO Ron Vachris said on the second-quarter earnings call that Costco would return any recovered tariff charges to members 'through lower prices and better values' and be transparent about how. Costco had sued the administration in late 2025 seeking a full refund of duties it paid.
Costco reports faster checkout from pre-scan pilot
On its fiscal second-quarter call, Costco said warehouses using pre-scan technology, in which employees ring up carts while members wait in line, had checkout speeds up to 20% faster, and that it was piloting automated pay stations averaging about eight seconds per transaction. Rivals Sam's Club and BJ's already offer app-based scan-and-go.
Shoppers sue Costco for share of tariff refunds
A proposed class action filed March 11, 2026 in federal court in Illinois (Stockov v. Costco) alleges Costco passed IEEPA tariff costs to members through higher prices and should not keep the refunds for itself; it quotes the CEO saying Costco raised some prices because members 'would be able to absorb' them. Costco's 10-Q lists four such class actions filed in March 2026, and Costco has moved to dismiss them as unripe.
Costco Velocity adds AI-targeted ads to Costco.com
Costco unveiled the next phase of Costco Velocity, its newly branded retail media network: a partnership with ad-tech firm Moloco to place AI-selected 'Reserved Display' ads on high-traffic pages including the homepage and search results, trained on members' purchase behavior. Beta partners got access in the second quarter of 2026, with more ad slots and programmatic buying planned through the third quarter.
Costco settles promo-email class action for $14 million
A Washington court preliminarily approved a $14 million settlement of a class action alleging Costco sent Washington residents promotional emails with false or misleading subject lines advertising limited-time discounts, such as 'Hot Buys available for 5 Days Only', in violation of the state's Commercial Electronic Mail Act and Consumer Protection Act. The class covers emails received from June 2021 through July 2026.
Costco receives tariff refunds while fighting customer suit
In an August 5, 2026 court filing, Costco said it had received about one-third of the IEEPA refunds it is owed and had begun returning the 'recovered value' to members through lower prices on some products, while still arguing that the customer's refund claims are unripe and should be dismissed. The plaintiff's lawyers called the lower-prices pledge 'shapeless adspeak'.
DOJ beef-pricing inquiry reaches Costco
The Justice Department widened its investigation into rising retail beef prices, sending letters in July to eight grocery retailers including Costco, Walmart, Kroger and Amazon asking for their beef pricing strategies, margins and costs from 2020 to 2026 and their wholesale arrangements with meatpackers. The request is industry-wide and alleges no wrongdoing by Costco.
Tariff refunds lift Costco's record fiscal 2026 profit
Costco reported fiscal 2026 net income of $9.226 billion on $297.2 billion in sales and $5.907 billion in membership fees. Fourth-quarter earnings included a non-recurring benefit of $0.15 per share from IEEPA tariff refunds, which the company described as net of partial reinvestment in lower member prices. The worldwide renewal rate was 89.8%.
