Overview

Executive Summary

Over the five years from FY2021 to FY2025, Tesla’s most consequential shift was the collapse of its operating leverage: revenue more than doubled to a peak of $96.8B in FY2023, then stagnated and declined to $94.8B by FY2025, while operating income fell 68% from its FY2022 high of $13.7B to just $4.4B. This deterioration was not driven by a single shock but by a persistent cost structure shift, R&D spending ballooned 41.2% in FY2025 alone, even as revenue shrank, and capital expenditure surged to $11.3B in FY2024 before pulling back. The company effectively traded margin for scale, then lost the scale.

Two themes run through every chapter. First, an inverse relationship between financial performance and narrative ambition: when revenue and operating income were surging in FY2021-FY2022, management downplayed AI and focused on operational challenges; when revenue stagnated and operating income collapsed in FY2024-FY2025, management resurrected AI as the core growth story, committing to over $20 billion in capex for 2026. Second, a hardening of risk and legal language that directly paralleled the financial deterioration, from a single closed SEC subpoena in FY2021 to multi-agency investigations, a jury verdict on Autopilot liability, and a formal framework agreement with the CEO’s AI venture by FY2025.

The numbers and the language disagree plainly. Management described the company as “self-funding” in FY2021, yet by FY2025 operating income was barely above the FY2021 level on a revenue base 76% larger. The company removed all mention of AI from its demand discussion in FY2022, then made AI the central strategic pillar in FY2025 as revenue declined. The risk factors shifted from fearing production delays to fearing demand miscalculation, yet the narrative simultaneously pivoted to speculative autonomous ride-hailing. The financial reality, stagnant revenue, collapsing margins, and a 38.5% operating income decline in FY2025, stands in stark contrast to the aspirational language of Robotaxi launches and AI infrastructure.

Chapter 01

Financial Performance

Audited figures for every year, as filed

Tesla’s financial performance over the five years from FY2021 to FY2025 traces a stark arc, from hypergrowth to stagnation, and from massive operating leverage to a capital-intensive reinvestment phase that has yet to pay off in reported earnings. Revenue more than doubled between FY2021 ($53.8B) and FY2023 ($96.8B), then plateaued, growing just 0.9% in FY2024 and declining 2.9% in FY2025 to $94.8B. Gross profit followed a similar but more aggressive pattern: peaking at $20.9B in FY2022 (+53.3%), then contracting each year to $17.1B by FY2025. Operating income collapsed from $13.7B in FY2022 to $4.4B in FY2025, a 68% decline, while net income fell from $12.6B to $3.8B over the same period. The deterioration in profitability was not driven by a single shock but by a persistent shift in cost structure. Research and development spending, which had risen modestly in FY2022, accelerated sharply: R&D grew 29.1% in FY2023, 14.4% in FY2024, and then ballooned 41.2% in FY2025 to $6.4B, even as revenue shrank. Selling, general and administrative expenses, after a rare decline in FY2022, resumed growth and reached $5.8B in FY2025. The company was spending more to generate less revenue.

The filings reveal the strategic intent behind this spending. In FY2024, Tesla added “AI infrastructure” as a separate line item within property, plant and equipment, carrying a net book value of $5.2B by year-end, up from $1.5B the prior year 1. This was the first explicit capital allocation to AI as a distinct asset class, and it coincided with a surge in total capital expenditure to $11.3B in FY2024, before a 24.8% pullback to $8.5B in FY2025. The cash flow narrative hardened as the operating metrics softened: the FY2024 filing added a strategic paragraph stating that management’s liquidity objectives included “invest in autonomy, do more vertical integration, expand our product roadmap” 2. That language was absent in earlier years, when the company was generating far higher returns on capital. The growing emphasis on autonomy was also reflected in the evolution of deferred revenue from Full Self-Driving capability. Revenue recognized from the FSD deferred balance more than doubled between FY2023 and FY2024, from $469M to $872M 3, and the FY2022 filing had first disclosed that the increase was “primarily related to the general FSD feature release in North America” 4. The company was booking cash from customers for a feature still in development, a dynamic that kept operating cash flow remarkably stable, hovering between $13.3B and $14.9B each year, even as net income deteriorated.

The balance sheet grew steadily, but the composition shifted in ways that warrant attention. Inventory more than doubled from $5.8B in FY2021 to $12.8B in FY2022, a 123% surge that reflected both production ramp and supply chain buildup 5. After peaking at $13.6B in FY2023, inventory fell 11.8% in FY2024, suggesting management began to address excess stock. But accounts receivable rose 54.3% in FY2022 and continued climbing, reaching $4.6B by FY2025, indicating that the company was extending more credit or facing slower collections. The accrued warranty reserve nearly doubled from $2.5B in FY2022 to $3.6B in FY2023, with the current portion alone rising from $1.0B to $1.5B 67. This was not a one-time adjustment; the reserve continued to grow, reflecting either higher expected repair costs or a larger vehicle base. Meanwhile, the company’s digital asset holdings underwent a dramatic accounting transformation. In FY2024, Tesla adopted fair value accounting under ASC 350-60, moving from the old impairment-only model 8. The impact was immediate: the FY2024 filing showed a beginning fair value of $487M for digital assets, upward adjustments of $638M, and an ending balance of $1,076M, with $589M in net unrealized gains recorded 9. This change introduced significant earnings volatility that had not existed before.

Tax disclosures also signaled a shift in financial posture. After a $5.0B income tax benefit in FY2023, likely driven by a valuation allowance release, the company recorded a $1.8B provision in FY2024 and a $1.4B provision in FY2025 10. The deferred tax asset valuation allowance increased from $892M in FY2023 to $1.22B in FY2024, now explicitly citing “U.S. foreign tax credits” as a component of the assets deemed not realizable 11. Net operating loss carryforwards halved from $2.8B to $1.3B over the same period 12, suggesting utilization of prior losses. The foreign tax provision rose steadily, from $1.24B in FY2023 to $1.32B in FY2024 13, consistent with growing international operations. More notably, the FY2023 filing removed the earlier commitment to meet Chinese government capital expenditure and tax revenue targets for the Shanghai site, along with the reversion risk language 14. That disclosure had been present in the FY2022 filing, and its deletion, without explanation, suggests either that the obligations were satisfied or that the terms were renegotiated. Given the subsequent revenue slowdown, the latter interpretation cannot be dismissed.

The FY2024 income statement recorded a $684M restructuring charge, the first such line item to appear in the five-year period 15. This coincided with the first year of automotive sales decline ($72.5B in FY2024, down from $78.5B) and a rise in regulatory credits to $2.8B, further evidence that the core vehicle business was under pressure. By FY2025, operating income had fallen to $4.4B, barely above the FY2021 level of $6.5B despite a revenue base that was 76% larger. The company had effectively traded margin for scale, and then lost the scale.

The Business

Strategy, segments, and geographic footprint

Tesla’s five-year narrative is one of profound strategic pivots, each accompanied by a hardening of language that often masked deteriorating financial performance. Revenue growth decelerated sharply from 51.4% in FY2022 to 18.8% in FY2023, then stalled at 0.9% in FY2024 before turning negative in FY2025, while operating income collapsed from a peak of $13.7B in FY2022 to $4.4B in FY2025. The company’s own description of its business shifted in ways that reveal both reactive management and a restless search for the next growth story.

The most striking early change was the replacement of a detailed responsible sourcing commitment, including a zero-tolerance policy on child and forced labor, with a generic ESG governance statement in FY2022 1. This removal of specific supply chain pledges occurred just as the company was beginning to acknowledge single-sourcing risk 2. By FY2024, the tone had hardened further, with the company explicitly describing its reliance on single suppliers and the mitigation strategies of safety stock and die banks 2. The financial context is telling: operating income had already fallen 34.9% in FY2023, and the supply chain language grew more defensive as margins compressed. The company that once boasted of economies of scale from shared components was now warning investors about procurement lead times.

The strategic center of gravity shifted repeatedly. In FY2022, Tesla removed a detailed discussion of over-the-air paid options and subscriptions, replacing it with a mission statement: “The very purpose of Tesla's existence is to accelerate the world's transition to sustainable energy” 3. This was a reframing for investors at a time of peak profitability, operating income had just doubled to $13.7B. The mission statement remained through FY2024, but by FY2025 it was gone, replaced by concrete product and service language: “We have planned electric vehicles … and will continue leveraging developments in our proprietary Full Self-Driving (FSD) (Supervised) features, battery cell and other technologies” 4. The Robotaxi business, announced in the FY2024 filing as a 2025 launch, had actually launched by June 2025, according to the FY2025 filing 45. But the FY2025 narrative also removed the Robotaxi and AI emphasis from the overview section, replacing it with a focus on energy storage software capabilities 6. The pivot was not linear; it was a whipsaw.

Geographic and regulatory themes intensified. The FY2022 filing removed the entire disclosure of the Shanghai government land agreement, including capital expenditure targets and tax revenue commitments 7. The earlier language had explicitly cited tariff mitigation as a reason for the factory, a risk that disappeared from the narrative. By FY2025, the company had reinserted language about international manufacturing in China and Germany, now explicitly framed as a way to “limit the impact of unfavorable tariffs” 8. The state of incorporation changed from Delaware to Texas in FY2024 9, a move with governance and legal implications. The most consequential regulatory shock came in FY2025, when the filing noted that the Inflation Reduction Act incentives were “substantially curtailed by the One Big Beautiful Bill Act (the ‘OBBBA’) enacted on July 4, 2025” 10. Residential solar tax credits expired on December 31, 2025 11. This regulatory reversal directly undermined the energy business that had been a growing narrative focus in earlier filings.

FY2023
Our products use thousands of parts that are sourced from hundreds of suppliers across the world. We have developed close relationships with vendors of key parts such as battery cells, electronics and complex vehicle assemblies. Certain components purchased from these suppliers are shared or are similar across many product lines, allowing us to take advantage of pricing efficiencies from economies of scale.
FY2024
As is the case for some automotive companies, some of our procured components and systems are sourced from single suppliers. Where multiple sources are available for certain key components, we work to qualify multiple suppliers for them where it is sensible to do so in order to minimize potential production risks due to disruptions in their supply. We also mitigate risk by maintaining safety stock for key parts and assemblies and die banks for components with lengthy procurement lead times.

The energy segment’s prominence waxed and waned. In FY2022, the company shifted from describing its electric vehicle service operations to detailing the marketing and sales of solar and energy storage products 12. By FY2024, the description of energy product expertise was replaced with a focus on vehicle sales channels 13. The energy storage warranty language expanded in FY2024, suggesting broader liability, but the strategic emphasis on energy software in FY2025 was quickly replaced by a renewed focus on battery cell R&D 1415. The company’s insurance product, launched in 2021, was removed from the business description by FY2024, replaced by energy system financing options 16.

The final year saw the most dramatic rewrite. The business overview was expanded to explicitly frame AI, Full Self-Driving, Robotaxi, and AI robots as core objectives 17. The ESG governance discussion was replaced by European regulatory restrictions on autonomous systems 18. The description of employee development programs was replaced by investments in compute infrastructure and a collaboration with Samsung for AI training 19. The Supercharger network, once described as proprietary and co-located with solar and storage, was now presented as an open partnership model 20. Each of these changes came as revenue declined 2.9% and operating income fell 38.5% in FY2025.

The patterns are consistent: as financial performance weakened, the company’s own narrative became more aspirational, more focused on future technology, and less anchored in the specific operational commitments that had characterized the earlier years. The removal of the Shanghai agreement, the dilution of supply chain ethics, the oscillation between energy and autonomy, and the regulatory dependence on IRA incentives that were later curtailed all point to a company that struggled to maintain strategic coherence under deteriorating financial conditions.

Risk Landscape

What management newly fears, and what it stopped fearing

Over the five years from FY2021 to FY2025, Tesla’s risk disclosures underwent a fundamental reorientation, mirroring the company’s financial trajectory from hypergrowth to stagnation and eventual revenue decline. What management feared in FY2022, rapid production scaling, supply chain bottlenecks, battery fires, had largely receded by FY2025, replaced by a new set of anxieties about demand, autonomous ride-hailing, tariffs, and the capital demands of artificial intelligence. The shift was not gradual but concentrated in two pivotal moments: the FY2022 filing, which introduced a torrent of new, specific risks tied to the Model 3/Y mass-market push, and the FY2025 filing, which laid bare the company’s post-growth strategy.

The most dramatic change came in the treatment of the core vehicle business. In FY2021, Tesla’s risk factors were still framed around operational execution: “Any delay or other complication in ramping the production of our current products” 1. By FY2022, as revenue surged 51.4% to $81.5B, the company abruptly replaced that language with a stark admission: “We are targeting with Model 3 and Model Y a global mass demographic… in which we have relatively limited experience projecting demand and pricing our products” 1. This was the first signal that management feared demand miscalculation more than production delays. That fear only deepened. By FY2025, with revenue contracting 2.9% to $94.8B and operating income down 38.5% to $4.4B, the risk factors explicitly warned of “difficulties in generating and maintaining demand for products manufactured” at new factories 2. The company that once feared not being able to build vehicles now feared not being able to sell them.

We are targeting with Model 3 and Model Y a global mass demographic with a broad range of potential customers, in which we have relatively limited experience projecting demand and pricing our products
Risk Factors (1A)

Concurrently, Tesla’s disclosed concerns about product liability and safety underwent a curious inversion. In FY2022, the company replaced a generic product liability risk with a highly specific warning about “battery fire and thermal runaway risk” for vehicles and energy products 3. This reflected both the growing installed base of high-voltage battery packs and the high-profile nature of EV fires. But by FY2023, that specific battery risk was removed entirely, replaced by a statement that the company was self-insured for product liability claims, meaning “any product liability claims will likely have to be paid from company funds and not by insurance” 4. The implied fear shifted from a technical failure to a financial exposure. By FY2025, a new risk appeared: “our products or features contain defects, fail to perform as expected or take longer than expected to become fully functional” 5, now explicitly covering software and hardware. The safety narrative had come full circle, from general liability, to battery fear, to self-insurance, to a fresh worry about feature delays.

The treatment of Elon Musk’s role is perhaps the most revealing barometer of Tesla’s evolving risk perception. In FY2021, the company stated plainly: “We are highly dependent on the services of Elon Musk, Technoking of Tesla and our Chief Executive Officer” 6. By FY2022, that language was removed entirely, replaced by a discussion of equity compensation philosophy 6. It was a deliberate attempt to de-risk the key-person narrative. But the respite was short-lived. In FY2023, the risk factor reappeared in a broader, more troubling form: “Although Mr. Musk spends significant time with Tesla and is highly active in our management, he does not devote his full time and attention to Tesla,” citing his roles at SpaceX and X Corp 7. The fear was no longer that Musk might leave, but that he was already distracted. This new formulation persisted into FY2025.

FY2025
Upon launching our Robotaxi service in June 2025, we also entered into the autonomous ride-hailing service market, and have plans to mass produce Cybercab, a purpose-built Robotaxi product. As we seek to expand the scope and geographical footprint of this business, our success will be dependent upon various factors, including the acceptance and adoption by consumers of autonomous driving solutions, and Robotaxi as a preferable option, amid growing competition. If the uptake rate for autonomous
Risk Factors (1A)

Autonomous driving technology evolved from a regulatory compliance risk to a full-blown commercial launch risk. In FY2022, Tesla introduced a specific risk factor for “Autopilot and FSD Capability” regulatory scrutiny 8, and separately warned of “governmental investigations and proceedings” 9. By FY2023, the competitive risk section was broadened to include “the market for self-driving technology and other vehicle applications and software” 10. Then, in FY2025, with the company’s financial performance deteriorating, a new risk appeared: “Upon launching our Robotaxi service in June 2025, we also entered into the autonomous ride-hailing service market, and have plans to mass produce Cybercab… our success will be dependent upon various factors, including the acceptance and adoption by consumers of autonomous driving solutions” 11. The risk had shifted from regulatory compliance to market adoption, a much harder, more uncertain bet.

Supply chain fears, which dominated the FY2022 update with explicit mentions of “semiconductor shortages” and “labor shortages” 12, were conspicuously absent from later filings. By FY2024, the risk language had pivoted from “scaling risks” to “new factory construction and demand risks” 2. The company had apparently solved its immediate supply chain problems, but the new problems, tariffs, trade restrictions, and the capital intensity of AI, were more strategic. In FY2025, Tesla replaced an ESG compliance risk with a detailed warning about “quotas, duties, additional tariffs, export controls” 13, reflecting the geopolitics of EV manufacturing across the U.S., China, and Germany. At the same time, the capital-intensive nature of the business was explicitly expanded to include “AI innovations, including growth in our fleet of AI-enabled company-operated assets and new businesses, such as our development and production of Bots” 14. The company’s risk profile had expanded beyond automotive into a multi-front technology gamble.

The removal of certain risks is as telling as their addition. Digital asset impairment risk, a unique feature of the FY2021 filing, was gone by FY2022 15. The detailed interest rate sensitivity analysis vanished in the same year 16. A specific risk about the SUNY Foundation lease was replaced first by customer credit risk 17, then by Bot development risks 18. The company that once feared Bitcoin impairment and interest rate fluctuations now feared losing the talent war: “Employees may leave Tesla or choose other employers over Tesla due to various factors, such as a very competitive labor market” 19. The compensation philosophy that had been a risk factor in FY2022 was replaced by a blunt retention warning.

The trajectory is clear. As Tesla’s revenue growth stalled and its operating income halved, management’s disclosed fears shifted from operational execution to demand, from supply chain to tariffs, from battery safety to autonomous ride-hailing, and from key-man dependence to distracted leadership. The FY2021 filing described a company that worried about building things; the FY2025 filing describes a company that worries about whether anyone will buy them, at what price, and under what trade regime.

Management's Discussion

How management explains its own numbers

Over the five years from FY2021 to FY2025, Tesla’s management narrative underwent a profound transformation, tracking a company that shifted from confident growth storytelling to defensive operational disclosure, then to a speculative AI-driven future. The arc is visible in how management explained its own numbers: the language hardened as the metrics deteriorated, and strategic priorities were rewritten almost annually.

In FY2021, the tone was one of self-funding momentum. Management described revenue growth of 71% and a 29.3% automotive gross margin, emphasizing that “our ability to be self-funding to continue as long as macroeconomic factors support current trends in our sales” 12. By FY2022, that confidence had already begun to fracture. Revenue growth slowed to 51.4%, and operating income surged 109.3% to $13.7B, but management’s language shifted from top-line celebration to cash flow emphasis: “Our business has recently been consistently generating cash flow from operations in excess of our level of capital spend” 3. The FY2022 filing also introduced a $1.50 billion bitcoin investment, a new capital allocation strategy that would later be quietly removed 14. Most tellingly, management removed all mention of “products based on artificial intelligence such as Autopilot and FSD” from its demand discussion, replacing it with “continuing challenges caused by vehicle transportation capacity” 5. The AI narrative was deliberately sidelined just as the company faced delivery bottlenecks.

MD&A (7)

FY2023 marked a decisive inflection. Revenue growth collapsed to 18.8%, and operating income fell 34.9% to $8.9B. Management’s explanation for automotive sales revenue growth of only 17% explicitly cited “lower average selling price on our vehicles driven by overall price reductions year over year, sales mix, and a negative impact from the United States dollar strengthening” 6. This was the first time management acknowledged price cuts as a primary driver of revenue deceleration. The cost side improved, average cost per unit decreased due to “lower inbound freight, a decrease in material costs and lower manufacturing costs” 7, but the narrative had shifted from growth to margin defense. Management also removed forward-looking capital expenditure guidance of $6-8 billion for 2023, replacing it with vague language about vendor agreements 8. The liquidity discussion pivoted from highlighting $16.25B in cash to detailing $4.68B in debt obligations, a defensive posture that signaled increased financial risk focus 9.

FY2024 brought outright revenue stagnation at $97.7B (+0.9%) and a 20.4% operating income decline to $7.1B. Management’s response was to introduce a $583 million restructuring charge for employee terminations, described as actions “to reduce costs and improve efficiency” 10. The business strategy section was rewritten to emphasize “risks and uncertainties inherent in establishing and ramping manufacturing operations,” including a production decline in Q1 2024 11. This was a stark reversal from the prior year’s optimistic language about cost reduction and affordability. The liquidity discussion swung back to strength, reporting $16.14B cash and $20.42B short-term investments 12, but the overall tone was one of retrenchment.

MD&A (7)

FY2025 saw revenue decline 2.9% to $94.8B and operating income plunge 38.5% to $4.4B. Management’s response was a dramatic pivot to AI-driven capital expenditure. The filing introduced a specific forecast that “capital expenditures to exceed $20 billion in 2026 driven by our AI initiatives, including investments in compute infrastructure and data centers” 13. This was accompanied by a new $390 million restructuring charge for “convergence of AI chip design efforts” 14. The business focus shifted entirely to “profitable growth via a differentiated and efficiently managed product portfolio that leverages our existing factories and production lines, further improving and deploying our FSD (Supervised) capabilities, including future autonomous capabilities through our purpose-built Robotaxi product, Cybercab” 15. The AI narrative that had been removed in FY2022 was now the central strategic pillar. Meanwhile, automotive regulatory credits revenue fell 28%, with management citing “governmental and regulatory actions, such as OBBBA, have restricted certain regulatory credit programs” 16. Tariffs also appeared for the first time as a cost factor for energy storage 17.

The most striking pattern across the five years is the inverse relationship between financial performance and narrative ambition. When revenue and operating income were surging in FY2021-FY2022, management downplayed AI and focused on operational challenges. When revenue stagnated and operating income collapsed in FY2024-FY2025, management resurrected AI as the core growth story and committed to $20 billion in capex. The restructuring charges, $583 million in FY2024 and $390 million in FY2025, were explained as efficiency measures, but they coincided with the worst operating income performance in the period. The digital asset investment, once a headline-grabbing $1.50 billion bitcoin purchase, was entirely removed from discussion by FY2023 4. The regulatory credit business, which had been a reliable profit contributor, was suddenly constrained by new rules 16. Management’s explanation for its own numbers evolved from confident self-funding to defensive cost-cutting to speculative AI investment, each shift reflecting a company struggling to maintain its growth narrative as the underlying metrics deteriorated.

Methodology

How this report was produced

This report is generated by a nine-stage pipeline over 5 consecutive 10-K filings retrieved directly from the SEC's EDGAR system. The raw filings are the single source of truth; nothing in this document is sourced from news, analyst commentary, or the language model's own knowledge of Tesla, Inc.

Parsing and anchoring. Each filing is parsed into sections and labelled with a stable anchor drawn from a fixed vocabulary: item1a_risk, item7_mdna, income_statement, and so on. Anchors matter because 10-K item numbering drifts between years and between filers: a section that is Item 7 in one year may sit at a different offset in the next. Anchoring gives every year a shared coordinate system. Coverage is asserted at ingest; if the critical anchors fail to resolve, the pipeline raises rather than silently producing a misaligned comparison.

Alignment. Sections are matched across years by anchor equality. Within each matched section, the text is split into paragraphs and every paragraph is embedded with a sentence-transformer model. Paragraphs are then aligned by cosine similarity, which tolerates the reordering, merging, and splitting that occurs between filings. Paragraphs with no counterpart above the similarity floor are recorded as additions or removals rather than forced into a spurious match.

Detection is deterministic. This is the load-bearing claim of the whole system. The language model never finds a change. Classification into unchanged, minor revision, and major revision is a function of cosine similarity against thresholds tuned on a hand-labelled sample. The thresholds are set for high recall deliberately: it is better to over-flag and let interpretation discard boilerplate than to miss a real change that never reaches a human.

The numeric guard. Cosine similarity has a specific blind spot: it is nearly insensitive to value-only changes. A sentence reporting revenue of $100 million and the same sentence reporting $489 million score above 0.99 and would be classified unchanged. A separate deterministic guard runs only over records the classifier called unchanged, extracts numbers from both years, and upgrades any record showing a material move. Where the section has audited XBRL backing, the guard corroborates against the filed financial tags. In this report the guard surfaced 314 changes that similarity alone would have discarded.

Interpretation is generative, and constrained. Only pre-verified change pairs are sent to a language model, and only to explain them. For each pair the model returns a summary, a materiality judgement, and short quotes evidencing the change. Every quote is then checked to be a literal substring of the filing text it claims to come from. A quote that fails is retried once; if it fails again the record is marked unvalidated and excluded from this report's prose. That check is what makes the citations in the chapters above trustworthy rather than plausible.

Composition. Chapter narratives are written from the surviving material and notable interpretations only, grouped by 10-K section. The writer sees the verified summaries, verbatim quote pairs, and the audited XBRL series, nothing else, and cites each claim back to a specific change record. Citations naming a record that does not exist are dropped before rendering, so the evidence drawer beneath each chapter can only contain real, quote-validated changes.

Financial figures. Every number in the Financial Performance tables comes from XBRL company facts as filed with the SEC, keyed by concept tag and fiscal year, preferring annual 10-K entries. No figure is extracted from prose or produced by the language model.

Limitations. Materiality is a model judgement and will not always match yours. High-recall thresholds mean the flagged count far exceeds the genuinely interesting count. Anchor-based alignment can misbehave if a filer restructures a section substantially between years. And the report describes what changed in the filing: a company that stops disclosing something produces a removal, which is not the same as the underlying fact having gone away.
