Four companies met our criteria from the six 10-K annual reports filed with the SEC on 22 July 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. A prior-year filing was not available for Star Gold Corp. and NaturalShrimp Inc, so they are excluded from the ranking.
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
- CAL-MAINE FOODS INC (High) — Cal-Maine is signaling a strategic pivot toward specialty, prepared foods and acquisitions, which could broaden growth but also increases execution risk.
- AAR CORP (High) — AAR is signaling a cleaner, higher-return portfolio by exiting legacy commercial programs and reorganizing around government, MRO, and software.
- Alzamend Neuro, Inc. (Medium) — Alzamend remains a financing-dependent development story with an unresolved control weakness and worsening cash consumption.
- RPM INTERNATIONAL INC/DE/ (Medium) — RPM’s biggest filing change is a segment reset that should improve management clarity but makes year-over-year segment comparisons less straightforward.

Cal-Maine’s filing shows a more explicit shift from being mainly a shell-egg producer to a broader egg-based food company with a dedicated prepared foods segment. Management is also leaning harder into acquisitions and branded specialty products as part of its growth plan. For investors, that points to a more diversified business model, but also a more complex integration story.
Main Changes
- The Business section now says the company is organized around three reportable operating segments: "Conventional Shell Eggs," "Specialty Shell Eggs," and "Prepared Foods," replacing the prior one-operating-segment structure.
- Management added a clear growth strategy: "expanding specialty shell eggs and prepared foods" and pursuing "disciplined growth through acquisitions" using scale, vertical integration, operational excellence and financial strength.
- The filing adds a broader product and brand description, including prepared foods such as egg patties, omelets, folded and scrambled egg formats, hard-cooked eggs, pancakes, waffles and specialty wraps, plus brands like Eggland’s Best, Land O’Lakes, Farmhouse Eggs, 4Grain, Sunups, Van’s, MeadowCreek Foods and Crepini.
- The company also disclosed recent acquisition activity in detail, including Echo Lake Foods, Clean Egg, Creighton Brothers and Deal Rite Feeds, reinforcing that M&A is now a core part of the business narrative.
Watch Items
- The move to separate Prepared Foods as a reportable segment signals a more diversified earnings mix and a push beyond the traditional egg business.
- Acquisition-led growth can accelerate scale, but it also raises integration, execution and capital-allocation risk if deals do not deliver expected synergies.
- The expanded emphasis on specialty and branded products suggests management is trying to reduce reliance on commodity egg pricing and improve margin stability.

Weak or unstable economic conditions, including continued high inflation and interest rates, may adversely affect our business by: ● Limiting our access to capital markets or increasing the cost of capital we may need to grow or operate our business; ● Changing consumer spending and habits and demand for eggs, particularly higher-priced eggs; ● Restricting the supply of energy sources or increasing our cost to procure energy; or ● Reducing the availability of feed ingredients, packaging material, and other raw materials, or increasing the cost of these items. Deterioration of economic conditions could also negatively impact: ● The financial condition of our suppliers, which may make it more difficult for them to supply raw materials; ● The financial condition of our customers, which may decrease demand for eggs or increase our bad debt expense; or ● The financial condition of…

| SEC filings | 2026 10-K HTML/iXBRL (SEC page, raw text) | 2025 10-K HTML/iXBRL (SEC page, raw text) |
AAR made a meaningful portfolio and reporting reset in this filing. It is combining some government and mobility activities, folding software into its repair business, and separating out a legacy commercial program that it plans to exit over the next three to four years. That points to a more focused business mix and a willingness to shed capital-intensive work that no longer fits its return targets.
Main Changes
- Management said it "changed our operating segment structure" by combining government programs and Mobility Systems into a new "Government Solutions" segment.
- The software platform was moved into the renamed "Repair, Engineering, and Software" segment, which now includes Trax, Aerostrat, Airvoyant and Airinmar.
- The remaining Integrated Solutions business was split out as "Legacy Commercial Programs," and AAR said it intends to exit that business because it "requires significant asset pools and no longer meets our capital return thresholds."
- The company also updated its segment descriptions to reflect the new mix, including renaming the U.S. government customer from "Department of Defense" to "Department of War" in the filing text.
Watch Items
- The planned wind-down of Legacy Commercial Programs signals a sharper capital-allocation focus and could improve returns if asset sales and contract runoff proceed cleanly.
- Moving software into Repair, Engineering, and Software suggests AAR sees digital tools as more tightly linked to its higher-margin MRO franchise.
- The new Government Solutions segment highlights a more explicit emphasis on government and mobility work, which may change how investors assess growth and margin mix.

Alzamend did not change its core control conclusion: management still says disclosure controls are ineffective because of a material weakness. The bigger business signal is in the cash flow update, where operating burn increased, investing spending dropped to zero, and financing inflows were materially lower than last year. That combination suggests the company remains highly reliant on outside funding while trying to keep development programs moving.
Main Changes
- The company kept the same conclusion that disclosure controls and procedures were "not effective due to the material weakness," but updated the evaluation date from April 30, 2025 to April 30, 2026.
- MD&A now says there were "no investing activities" in 2026, versus $300,000 of equipment purchases in 2025 for AL001 Phase II clinical trials.
- Financing cash inflow fell to $4.8 million in 2026 from $10.4 million in 2025, with the mix shifting to $4.1 million from convertible preferred stock and $800,000 from ATM proceeds.
- Operating cash use widened to $8.1 million in 2026 from $6.6 million in 2025, while net cash moved from a $3.6 million increase to a $3.2 million decrease.
Watch Items
- The unchanged material weakness keeps financial reporting risk elevated and suggests remediation is still not complete.
- The absence of investing activity may indicate a pause in clinical or equipment spending, which could reflect tighter capital discipline or slower execution.
- Lower financing inflows and higher operating burn point to continued dependence on external capital to fund AL001 and ALZN002 development.

RPM reorganized its reporting structure and now presents results in three segments instead of four. The company also updated its business description to reflect higher sales, a wider international footprint and a slightly larger manufacturing base. Overall, the filing reads like a portfolio and reporting cleanup rather than a major change in strategy.
Main Changes
- The company moved from "four reportable segments" to "three reportable segments" effective June 1, 2025, saying the realignment reflects how it "allocate[s] resources and analyze[s] the operating performance" of the business.
- RPM shifted reporting units out of Specialty Products Group: Legend Brands moved to Construction Products Group, Industrial Coatings Group and Food Group moved to Performance Coatings Group, and Color Group moved to Consumer.
- The business description was updated to show a larger scale, with net sales rising to "$7.9 billion" from "$7.4 billion," international markets increasing to "approximately 167 countries and territories" from 163, and manufacturing sites rising to "approximately 120" from 118.
- The brand list was refreshed, adding names such as Kalzip and Ready Seal while removing some prior names, indicating portfolio updates rather than a wholesale business model change.
Watch Items
- The segment realignment can change how investors read growth and margin trends, since prior-period comparisons will no longer map cleanly to the old reporting structure.
- Moving businesses into CPG, PCG and Consumer suggests management wants a cleaner operating model and may be positioning the portfolio around stronger end-market alignment.
- The higher sales base and broader geographic reach point to continued scale expansion, but investors should watch whether the new structure improves accountability and segment profitability.

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.
