The FY2026 10-K shows a real, durable lock but not an unassailable one. On the durable side: "Our cloud storage services are based on the same ONTAP data management software that underpins our on-premises ONTAP storage infrastructure offerings", and the same filing's income statement shows the company holding a gross margin near 71% across all three reported years - $4,433M on $6,268M in FY2024, $4,613M on $6,572M in FY2025 and $4,899M on $6,925M in FY2026 - while revenue grew from $6,268M to $6,925M and income from operations widened from 19% to 24% of net revenues. Holding that margin through the memory-cost shock the same filing discloses is the commercial evidence the lock is worth something. On the limiting side, the filing says competition "is intense", that in public cloud "customers may choose native cloud services that are consumed as operating expenses", and that "New competitors or alliances among existing competitors could emerge and quickly gain significant market share" - and IDC's 1Q26 external-storage tracker (Blocks & Files, 2026-06-16, cited on the AFF/ASA product row below) ranks NetApp second behind Dell, not first.

Baidu's search franchise still leads, but it earns less each year and the company has written part of it down. Its 2025 annual report on Form 20-F (https://www.sec.gov/Archives/edgar/data/1329099/000119312526109289/d38065d20f.htm) says revenue from online marketing services "declined in 2024 and 2025, primarily due to our ongoing AI transformation, which impacted the monetization approach, as well as unfavorable macroeconomic conditions", and that "the increasing prevalence of AI-powered search engines and virtual assistants is fundamentally altering user behavior", so that users "may have less need to click on traditional search results or sponsored links". In 2025 it recognised RMB16.2 billion of impairment losses on its Core asset group after a recoverability test it attributes to "fluctuations in the external environment, in particular the rapid iteration of AI technology, and changes in our internal operations", and reported an operating loss of RMB5.8 billion (operating income of RMB10.4 billion excluding the impairment). The decline continued into 2026: the second-quarter results (https://ir.baidu.com/news-releases/news-release-details/baidu-announces-second-quarter-2026-results, 2026-08-18) show what Baidu calls Legacy Business revenue at RMB10.4 billion, down 23% year over year, and the CEO says "our online marketing business remains under pressure". The lead itself is still large by an independent count, with StatCounter putting Baidu at 46.65% of China's search engine market in September 2026. A lead that monetises less each year, and has needed an impairment, is an eroding moat.

The FY2025 Form 10-K describes an edge that holds on large, complex work but not across the trade. On the advantage side, it says an invitation to bid "is often conditioned upon prior experience, technical capability, and financial strength", that its largest projects "typically require significant technical and management skills and the financial strength to obtain performance bonds, which are often a condition to bidding for and winning these projects", and that those projects "represented approximately 58% of our electrical and mechanical construction services revenues in 2025". It adds: "We believe our financial position, operating results, access to bank credit and surety bonding, technical expertise including prefabrication, VDC, and BIM capabilities, and safety record, among other factors, give us an advantage over many of our competitors." Operating margin was 10.1% in 2025 against 9.2% in 2024, and the filing notes the 2025 figure includes a $144.9 million gain on the sale of the United Kingdom operations that "positively impacted operating margin by 85 basis points". On the limiting side, the same Competition section says "relatively few barriers exist to prevent entry into the electrical and mechanical construction services industry" and "there are relatively few barriers to entry into the building services industry". Item 1A adds that "Certain of our competitors have lower overhead cost structures and, therefore, are able to provide their services at lower rates than we are currently able to provide" and that work "is frequently awarded through a competitive bidding process". An advantage confined to bonded, technically demanding projects, in a trade the company itself calls easy to enter, is a narrow moat, not a wide one.

The FY2026 10-K makes the source of the advantage explicit and it is the cost of leaving the data-management layer, not a network or a patent estate. The same ONTAP software runs the on-premises arrays and the cloud services ("Our cloud storage services are based on the same ONTAP data management software that underpins our on-premises ONTAP storage infrastructure offerings"), and the AFF family "allows customers to connect to clouds for more data services, data tiering, caching, and disaster recovery". A customer's volume layout, snapshot and replication workflow and operating tools therefore carry from the array into Azure, AWS and Google rather than being abandoned at the cloud boundary — the filing describes NetApp as "the only provider of enterprise-grade storage services natively embedded in the world's largest public cloud providers", so the usual moment of escape is instead the moment the relationship renews.

The moat Baidu is losing is a traffic-driven network. The 20-F says it competes for users and customers "on the basis of user traffic, cyber security, quality (relevance) of search (and other marketing and advertising) results, availability and user experience of products and services, distribution channels and the number of associated third-party websites", and that its content ecosystem depends on attracting creators "by leveraging our user traffic and enhance user engagement through the provision of attractive content, so as to create a virtuous cycle". Advertisers use its P4P platform "to bid for priority placement of paid sponsored links and reach users who search for information related to their products or services", and Baidu Union partners carry its search engine and ads on their own properties. AI answers are weakening that loop: the same filing warns that conversational tools risk "reducing traffic to our platforms and diminishing the inventory and effectiveness of our search-based advertising", and Baidu App's monthly active users were 644 million in June 2026 (second-quarter results) against 679 million in December 2025 (20-F).

The 10-K places the advantage in capabilities that come with size rather than in customer lock-in or protected technology. The edge it names is "financial position, operating results, access to bank credit and surety bonding, technical expertise including prefabrication, VDC, and BIM capabilities, and safety record", delivered through "approximately 100 operating subsidiaries" and approximately 44,000 employees. MD&A credits the mechanical construction segment's 2025 result to "a more favorable mix of work and better project execution, including enhanced productivity, due in part to investments in virtual design and construction, prefabrication, and automation". Item 1A makes bonding a scale matter: "if we were to experience an interruption or reduction in the availability of bonding, we may be unable to compete for or work on certain projects." The filing cites no patents as a source of advantage, and switching costs are thin by its own account: "Many of our contracts, especially our building and industrial services contracts, may be canceled or delayed on short notice".

IDC's 1Q26 external enterprise storage systems tracker, as reported by Blocks & Files on 2026-06-16 (cited in full on the AFF/ASA product row below), ranks NetApp second worldwide behind Dell and ahead of Everpure, Huawei and HPE, attributing the placing to "its growing all-flash business and cloud-integrated data management". Second of five ranked vendors, in a market whose leader is someone else, is a shared front rank rather than an owned one - and the distinct claim NetApp makes in the FY2026 10-K is positional rather than volumetric: being "the only provider of enterprise-grade storage services natively embedded in the world's largest public cloud providers".

Baidu leads search by an independent count, but not the AI businesses that now make up half of its core revenue. StatCounter (https://gs.statcounter.com/search-engine-market-share/all/china, September 2026 figures) puts Baidu at 46.65% of China's search engine market across all platforms, against 21.76% for Bing, and at 60.15% on mobile, though on desktop it shows Bing ahead at 41.27% to Baidu's 28.32%. In AI cloud, the 20-F cites IDC's ranking of Baidu AI Cloud as "the No.1 AI cloud provider for the sixth consecutive year" in China's AI public cloud market for 2024, but that figure is relayed by Baidu and covers 2024, and IDC data reported by KrASIA (https://kr-asia.com/how-bytedances-volcano-engine-holds-nearly-half-of-chinas-maas-market, 2026-05-13) put ByteDance's Volcano Engine at 49.5% of China's model-as-a-service market in 2025. In models, Artificial Analysis's leaderboard (https://artificialanalysis.ai/leaderboards/models, read 2026-10-10) gives ERNIE 5.0 Thinking Preview an estimated Intelligence Index of 14, against 45 for Alibaba's Qwen3.8 Max (0902) and Z AI's GLM-5.3 (max). A clear lead in search alongside a contested AI cloud position and a lagging model family makes Baidu a co-leader rather than a clear leader.

The 10-K gives no market share. It calls the field "highly fragmented" with "thousands of small companies across the United States", adds that "there are a number of larger companies focused on providing electrical and/or mechanical construction services, such as APi Group Corporation, Comfort Systems USA, Inc., Dycom Industries, Inc., Everus Construction Group, Inc., IES Holdings, Inc., MasTec, Inc., MYR Group Inc., Quanta Services, Inc., and Tutor Perini Corporation", and describes EMCOR as "one of the largest specialty contractors in the United States", which is the company's own account. Outside the filing: Wikipedia's EMCOR article (https://en.wikipedia.org/wiki/Emcor) states that "In 2025, the company was ranked 2nd by Engineering News-Record on its list of the largest 600 specialty contractors by revenue"; its footnote links ENR's 2025 Top 600 preview page, which refused this fetch with HTTP 403, so the rank was not read at ENR itself (the footnote's title also reads 2024 while its link is the 2025 page). Statista's summary of the ENR survey for 2018 (https://www.statista.com/statistics/467307/leading-us-firms-in-mechanical-based-on-revenue, published Oct 21, 2019) says "EMCOR Group was ranked as the leading mechanical contractor based in the United States in 2018" and that the overall survey was "topped by electrical contractor Quanta Services and closely followed by EMCOR Group". A filing-based check agrees on scale against one named rival: stored fundamentals from the FY2025 10-Ks show EMCOR revenue of $16,986,422 thousand against $9,101,641 thousand for Comfort Systems USA (https://www.sec.gov/Archives/edgar/data/1035983/000110465926017530/0001104659-26-017530-index.htm). Second place on a revenue ranking of 600 specialty contractors, in a field the 10-K says has thousands of firms, is co-leadership rather than clear leadership; the ranking evidence is second-hand or dated, so the band is held at co-leader and no higher.

It holds price rather than raising it. On the figures filed with the FY2026 10-K, gross margin was 70.7% of revenue in FY2024 ($4,433M on $6,268M), 70.2% in FY2025 ($4,613M on $6,572M) and 70.7% in FY2026 ($4,899M on $6,925M) - flat across three years in which revenue grew from $6,268M to $6,925M - and it held that level while absorbing a component-cost shock. It is no stronger than that because the filing's own risk factor lists "competitive pricing, customer price sensitivity" and "pricing and discounting pressures" among the drivers of gross margin, and discloses that the company "experienced inflationary pressure and supply chain constraints beginning in the second half of fiscal 2026, resulting in increased costs for memory and other components, which have affected our gross margins" - a cost shock it is absorbing rather than fully passing on.

Costs are rising faster than revenue, and Baidu has been cutting model prices. In 2025, per the 20-F, Baidu General Business revenue fell 2% to RMB102.5 billion while its cost of revenues rose 15% from RMB44.8 billion to RMB51.5 billion, "mainly related to development of cloud services", and the filing warns of "downward pressure on our operating margin". Online marketing revenue fell in both 2024 and 2025, and Legacy Business revenue was down 23% year over year in the second quarter of 2026. Baidu says it released ERNIE 4.5 Turbo and ERNIE X1 Turbo "delivering improved performance at significantly lower pricing, making them among the most cost-effective options on the market", and IDC data reported by KrASIA says the model-as-a-service leader Volcano Engine's "per-token price was below the industry average". The one premium claim, that AI-native marketing customers are "willing to pay a premium", is Baidu's own, and that line's revenue was "approximately flat year over year" in the second quarter of 2026.

Margins have widened, but the filing says most work is bid. The 2025 Annual Report's five-year highlights show gross profit of $1,501,737 thousand on revenues of $9,903,580 thousand in 2021, $2,089,339 thousand on $12,582,873 thousand in 2023 and $3,282,988 thousand on $16,986,422 thousand in 2025; MD&A gives gross profit margin of 19.3% in 2025 against 19.0% in 2024. The Q2 2026 release (https://emcorgroup.com/application/files/3517/8535/6062/2Q26_Earnings_Release_Final.pdf) reports operating margin of 10.6% against 9.6% a year earlier, and the chief executive said "We remain focused on maintaining pricing discipline, carefully selecting project opportunities, and executing at a high level across our operations." The limits are in the 10-K: "Competition can place downward pressure on our contract prices and profit margins"; on commodities, "While we believe we can increase our prices to adjust for some price increases in commodities, there can be no assurance that price increases of commodities, if they were to occur, would be recoverable", and "certain of our contracts do not allow us to adjust our prices"; and Note 3 shows projects whose profitability was revised down by more than $1.0 million each reduced operating results by $85,941 thousand in 2025, against $66,319 thousand in 2024.

NetApp sits between the memory supply and the enterprise data centre. Upstream, the FY2026 10-K says "Third-party component costs make up a significant portion of our product costs" and singles out NAND as hard to manage "if supplies of certain components, including NAND, become limited relative to demand". Downstream, the hyperscalers are channel, partner and rival at once: the filing states "We both partner with and compete against cloud service providers through our cloud-based software and services offerings", while Azure NetApp Files, Amazon FSx for NetApp ONTAP and Google Cloud NetApp Volumes are delivered as those clouds' own natively embedded services. Distribution is a mix of direct sales and "an ecosystem of partners, including the leading cloud providers".

Baidu spans several layers of China's AI stack. Its 20-F describes "a full AI stack of four layers, including cloud infrastructure, deep learning framework developed in-house, foundation models, and applications", with AI infrastructure "powered by a diverse mix of domestic and international high-performance computing resources, including our own self-developed AI computing architecture" and its own Baidu AI Chip. It sells GPU Cloud capacity and Qianfan model services to enterprises and the public sector, with a Qianfan model library that includes "leading third-party and open-sourced models" as well as ERNIE, and it funds this largely from online marketing sold to advertisers through search and feed.

EMCOR builds the electrical and mechanical plant inside facilities, increasingly data centres: the 10-K says capital spending on data center infrastructure "is rapidly expanding, which has increased demand for our services in recent years". It works directly for owners and "indirectly by acting as a subcontractor to general contractors, systems suppliers, construction managers, developers, property managers, and other subcontractors". Upstream, "we rely on third-party vendors and manufacturers to supply much of the materials and equipment necessary for our operations", with commodity exposure to "copper and steel" and fuel for a fleet of approximately 14,400 vehicles.
