Pricesmart (PSMT) 10-K: Business Changes Lead 26 October 2026 Filing Roundup

Pricesmart (PSMT)’s Business section changed the most among 4 companies that filed 10-Ks on 26 October 2026, each compared against its prior-year filing.

SEC What Changed — 26 October 2026 10-K filing snapshot
PSMT+42.83%
GBX-13.83%
WDFC+12.72%
AZO-16.36%

Four companies met our criteria from the four 10-K annual reports filed with the SEC on 26 October 2026. To qualify, a company must have filed an annual 10-K report on the target date and have a prior-year 10-K available for a direct year-over-year comparison.

SEC What Changed Methodology

Each company is scored on how similar its current annual filing text is to the prior year. Scores run from 0 to 1 — a score of 1 means the language is essentially unchanged; a lower score means more has changed. We flag three sections that carry the most disclosure signal: Business, Risk Factors, and MD&A. Recent research suggests that lower scores indicate that a company has made significant changes to their filings, these changes are often buried in the filings. If a company was to report positive news, they would likely do so in the form of a press release or statement on their website. The large changers have often underperformed in the market, while the stable-language filers have earned positive abnormal returns.

Key Takeaways

  • PRICESMART INC (Medium) — PriceSmart is still in growth mode, with more stores, a first Chile opening, and a wider supply chain pointing to continued expansion rather than a pause.
  • GREENBRIER COMPANIES INC (Medium) — Greenbrier is flagging AI as a new competitive and operational risk while also widening its tax caution, but the filing does not suggest a major change in business direction.
  • WD 40 CO (Medium) — The biggest signal is that WD-40 is now flagging a possible divestiture and the execution risks that could come with it.
  • AUTOZONE INC (Low) — This filing is mostly a clean rollover, with only a modestly broader reputational risk warning and slightly higher self-insurance exposure.

PriceSmart’s business section now reflects a larger footprint, with 58 clubs versus 56 last year and several more openings planned, including Chile. The company also broadened its supply-chain description to include distribution centers in China and updated its sourcing language to emphasize U.S. and global supply. Overall, the filing points to continued expansion and a more complex operating network.

Main Changes

  • The company now says it had "58 warehouse clubs" as of August 31, 2026, up from 56 a year earlier, and the club count table shows five anticipated openings in fiscal 2027, including a first club in Chile.
  • The business description shifts from saying merchandise is sourced from "the rest of the world" to being sourced from "the United States and globally," and it adds that the company operates distribution centers "in China."
  • PriceSmart changed its wording from a "mission" to an "objective" and from "our business model" to "our Company," while also updating employee count to "over 13,000" from "over 12,000" and adding "vision screening" to the community program description.
  • The filing adds a specific Jamaica project update: the company "executed a land lease" for a fourth warehouse club in Kingston that is under construction and expected to open in December 2026.

Watch Items

  • The store-count increase and Chile entry signal continued unit growth, which can support revenue expansion if new clubs ramp as planned.
  • Adding distribution centers in China suggests a broader supply-chain footprint, which may improve sourcing flexibility but also adds execution complexity.
  • The Kingston lease and multiple planned openings show management is still leaning into expansion, so investors should watch capital spending and opening cadence.

Important Filing Changes

Added: The filing adds a new tariff disclosure describing Supreme Court, Section 122, Section 301, Section 232, and other tariff changes.

2025 filing excerpt – Risk Factors

We are vulnerable to changes in political and economic conditions, including the effects of tariffs and/or international trade wars and disruptions to remittances. [No corresponding passage in the 2025 filing.] The U.S. government has implemented significant tariff measures, including a baseline tariff of 10% on products from all countries and higher rates targeting specific countries such as China, Vietnam, and the European Union.

2026 filing excerpt – Risk Factors

We are vulnerable to changes in political and economic conditions, including the effects of tariffs and/or international trade wars. The U.S. tariff landscape remains volatile: the Supreme Court struck down IEEPA-based tariffs in February 2026, prompting the administration to shift to a temporary Section 122 surcharge, then new Section 301 duties (10%–12.5%) on goods from about 80 countries, while existing Section 232 and other Section 301 tariffs remain in effect. Given this shifting legal and statutory landscape, we cannot predict what tariffs, duties, or reciprocal measures will be in effect at any given time, how long they will remain in place, or how other countries will respond, and this uncertainty may affect our operations and our ability to supply merchandise at reasonable prices at our warehouse clubs.

Removed: The company no longer presents the August 31, 2025 club location table and related Dominican Republic and Jamaica footnotes.

2025 filing excerpt – MD&A

Our FVPIS spent over three decades in federal law enforcement working in cyber related roles. Properties At August 31, 2025, PriceSmart operated 56 membership warehouse clubs, as detailed below: Location Own land and building Lease land and/or building COLOMBIA SEGMENT Colombia 9 1 CENTRAL AMERICA SEGMENT Costa Rica 9 — El Salvador 4 — Guatemala 3 4 Honduras 2 1 Nicaragua 2 — Panama 6 1 CARIBBEAN SEGMENT Aruba — 1 Barbados 1 — Dominican Republic (1) 5 — Jamaica (2) 2 — Trinidad 3 1 USVI — 1 Total 46 10 (1) The Company purchased land located in La Romana, Dominican Republic, where we plan to open our sixth warehouse club in Dominican Republic in the spring of 2026. (2) The Company purchased land located in Montego Bay, Jamaica, and leased land located on South Camp Road, Jamaica, where we plan to open our third and fourth warehouse clubs in Jamaica in the summer and fall of 2026, respectively. Although we have entered into real estate leases in the past and will likely do so in the future, our current preference is to own rather than lease real estate.

2026 filing excerpt – MD&A

[No corresponding passage in the 2026 filing’s MD&A section.]

Added: The filing adds disclosure of the One Big Beautiful Bill Act and its tax changes effective for tax years beginning after December 31, 2025.

2025 filing excerpt – Risk Factors

As part of the settlement, we will pay the minimum tax on a go-forward basis. [No corresponding passage in the 2025 filing.] A few of our stockholders own approximately 14.8% of our voting stock as of August 31, 2025, which may make it difficult to complete some corporate transactions without their support and may impede a change in control.

2026 filing excerpt – Risk Factors

As part of the settlement, we will pay the minimum tax on a go-forward basis. In July 2025, the United States enacted significant tax legislation commonly referred to as the One Big Beautiful Bill Act ("OBBBA"), which makes permanent many provisions of the Tax Cuts and Jobs Act of 2017 and introduces additional changes affecting individuals and businesses, including continuation of the 21% federal corporate income tax rate, enhancements to bonus depreciation and expensing rules, and modifications to certain international tax provisions such as the renaming and restructuring of the Global Intangible Low-Taxed Income ("GILTI") regime as Net CFC Tested Income ("NCTI") and the Foreign-Derived Intangible Income ("FDII") deduction as Foreign-Derived Deduction Eligible Income ("FDDEI"), effective for tax years beginning after December 31, 2025, which corresponds to our fiscal year 2027. We have reviewed the OBBBA and continue to monitor and model its potential impact on our operations and effective tax rate, and based on our analysis of the Company’s operating profile, the OBBBA did not have a material effect on our fiscal year 2026 results; however, this conclusion is based on current guidance and our present understanding of the law, which remains subject to further interpretation, implementing regulations, and potential legislative or regulatory changes, and our future results could differ from our current expectations if such developments occur or if our operating profile changes.

SEC filings2026 10-K HTML/iXBRL (SEC page, raw text) | 2025 10-K HTML/iXBRL (SEC page, raw text)

Greenbrier’s risk factors now include a new warning on artificial intelligence and a broader description of tax-related disputes. The AI language says poor implementation could hurt operations, raise costs, or create legal and reputational problems, while the tax update widens the scope from IRS challenges to tax audits, disputes, and litigation more generally. Overall, the filing reads as a modest but meaningful expansion of risk disclosure rather than a major strategic reset.

Main Changes

  • The risk factor on tax matters was expanded from a narrower warning that the IRS or other tax authorities could contest positions and require additional taxes, interest or fines to a broader statement that "tax audits, disputes and litigation" may adversely affect results of operations, financial condition or cash flows.
  • Greenbrier added a new risk factor stating that "the use of artificial intelligence technologies could adversely affect our business and competitive position," including operational issues, higher costs, reputational harm or legal liability if implementation goes poorly.
  • The AI disclosure also says Greenbrier may miss efficiency gains or fall behind competitors if it does not successfully identify and implement relevant AI applications.

Watch Items

  • The new AI language signals management sees emerging technology as both an execution risk and a competitive issue, which could matter if the company is investing in automation or digital tools.
  • The broader tax wording suggests management wants to cover a wider range of disputes and litigation outcomes, which can imply more caution around cash flow and earnings volatility.
  • Neither change appears to indicate a near-term crisis, but both add incremental downside risk to margins and operating flexibility.

Reworded

2025 filing excerpt – Business

The uncertainty of the tariffs, including a potential increase in costs and decrease in demand for our products, could heighten the other risks factors and uncertainties discussed in this Item 1A, or in other reports we periodically file with the SEC, and impact our financial condition or results of operations. Furthermore, our competitors may be less exposed to tariff impacts or in a better position to mitigate the increased costs of tariffs. Increases in the price of materials and components used in the production of our products could negatively impact our profit margin on the sale of our products.

2026 filing excerpt – Business

Ongoing uncertainty in these areas, including the administration of trade policy in North America, has adversely affected and may continue to adversely affect North American industry-wide demand for new railcars, and therefore, our results of operations. Furthermore, as a result of 11 the Determination, our competitors may be less exposed to tariff impacts, including the Section 232 tariffs, or in a better position to mitigate the increased costs of tariffs. Additionally, from time to time, businesses in the U.S. petition the Department of Commerce under the U.S.

SEC filings2026 10-K HTML/iXBRL (SEC page, raw text) | 2025 10-K HTML/iXBRL (SEC page, raw text)

WD-40’s filing now talks much more openly about a possible divestiture, including closing timing, proceeds, and how the company might use the cash. It also adds new concern around leadership transition and a more specific warning that switching to new third-party manufacturers could disrupt supply. Overall, the update reads as a more cautious disclosure set around strategy and operations.

Main Changes

  • The forward-looking statements now explicitly include "expected benefits from any divestiture transaction," the "ability to successfully complete any planned divestiture," expected proceeds, timing, and use of proceeds, plus the possible impact on stock price and EPS.
  • New risk language was added around "ability to manage the transition and effectiveness of interim or newly appointed leadership," signaling management turnover or succession is now a disclosed concern.
  • Supply chain guidance was expanded to mention "potential disruptions from transitions to new third-party manufacturers," adding a more specific operational risk than the prior generic supply chain wording.
  • The company also broadened macro risk references to "geopolitics" and input-cost changes linked to commodity prices, while removing the prior standalone reference to "inflationary trends" in the same form.

Watch Items

  • A divestiture would be a strategic reset and could change the company’s portfolio mix, capital allocation, and earnings profile.
  • Leadership-transition language suggests investors should watch for execution risk if management changes are underway or anticipated.
  • The added third-party manufacturer risk points to possible near-term disruption in sourcing, production, or service levels.

Important Filing Changes

Removed: The cybersecurity incident disclosure and related policies were removed.

2025 filing excerpt – Risk Factors

Techniques used in these attacks change frequently and may be difficult to detect for periods of time. Although we have policies and procedures in place governing (i) the timely investigation of cybersecurity incidents, (ii) the timely disclosure of any related material nonpublic information resulting from a material cybersecurity incident, and (iii) the safeguarding against insider trading by directors, officers, and other corporate insiders between the period of investigation and the public disclosure of such an incident; cybersecurity incidents themselves, such as the release of sensitive data from our databases and systems, could adversely affect our business, financial condition and results of operations. The increasing number of information technology security threats and the development of more sophisticated cyberattacks, which includes the adoption of emerging technologies such as AI and machine learning, as well as other techniques such as ransomware, pose significant potential risks to the security of our information technology systems and networks, as well as to the confidentiality, availability and integrity of our data.

AutoZone’s risk factors were mostly carried forward with no major new business risk disclosed. The main substantive tweak is a broader warning around corporate responsibility goals, where a delay or perceived failure could hurt public perception, customer or stockholder support, and trigger legal claims. The filing also shows a larger self-insurance sensitivity, implying slightly higher exposure to claims cost swings.

No material section-level wording change was large enough to quote from the compared sections.

Why SEC Filing Changes Matter

Research by Cohen et al. (Lazy Prices, 2020) — using the complete history of SEC filings from 1995 to 2014 — shows that when firms make active changes to their annual disclosures, those changes convey an important signal about future operations and returns. A portfolio that shorted "changers" and bought "non-changers" earned over 22% per year in annual alpha historically. Changes to the Risk Factors section, Business description, and language referring to the executive team were especially informative. Critically, these returns accrued gradually as information was later revealed through news and earnings — not at the time of filing — suggesting many investors remain inattentive to these simple, public signals. This snapshot is a starting point for deeper investigation, not a buy or sell recommendation.
