Trane's FY2025 Form 10-K (filed 5 February 2026) makes exactly one rank claim about itself and it is hedged: 'We are one of the leading manufacturers in the world of HVAC systems and services and transport temperature control products and services'. It sits inside a Competitive Conditions section that opens 'Our products and services are sold in highly competitive markets throughout the world', describes 'a wide variety of competitors that vary by product line and services' including 'well-established regional or specialized competitors, as well as larger U.S. and non-U.S. corporations or divisions of larger companies', and names price first among 'the principal methods of competition in these markets', ahead of quality, delivery, service and support, technology and innovation. The risk factors push the same way: 'The markets that we serve are highly competitive', 'consolidation and new entrants (including non-traditional competitors) within our industries' 'could result in increased competition and pricing pressures', Trane competes 'with large companies and with smaller, local operators who may have customer, regulatory or economic advantages in the geographies in which they are located', and 'some of our competitors may employ pricing and other strategies that are not traditional'. What the filing does evidence is an advantage that gets paid for: 2025 net revenues of $21,321.9 million, up 7.5% from $19,838.2 million, of which the company's own bridge assigns 3.0 points to pricing; gross margin up 50 basis points to 36.2%; operating income of $3,967.4 million, 18.6% of revenues; and firm backlog up to $7,769.4 million from $6,747.7 million. But that advantage is not uniform in the same document: the EMEA pricing component was (0.3)% and its segment adjusted EBITDA margin fell 150 basis points to 18.3%, and Asia Pacific organic revenue fell 2.5% on 'lower volumes in China'. A position the company itself will only call 'one of the leading', defended in markets it calls highly competitive and priced unevenly across its three segments, is protection that is real but bounded.

Semtech’s FY2026 10-K (fiscal year ended January 25, 2026) supports a narrow moat and no more. On the durable side, it owns the LoRa® radio franchise - “our LoRa® devices and wireless radio frequency technology” - which IoT Analytics’ LPWAN Market 2024 release (https://iot-analytics.com/wp-content/uploads/2024/03/INSIGHTS-RELEASE-LPWAN-Market-2024.pdf) ranks first outside China at 41% of LPWAN connections, and it argues that scarce analog talent “has historically made it more difficult for new suppliers in the analog market to quickly develop products and gain significant market share.” On the limiting side, the same filing says its patents do not “create definitive competitive barriers to entry”, that average selling prices “have historically decreased rapidly”, that some customers “can stop incorporating our products into their own products with limited notice to us and suffer little or no penalty”, and that customers in China (including Hong Kong) were 47% of fiscal 2026 net sales. The record is uneven: its income statement shows gross profit of $296,250 thousand on net sales of $868,758 thousand in fiscal 2024, $456,528 thousand on $909,287 thousand in fiscal 2025 and $542,144 thousand on $1,049,975 thousand in fiscal 2026, and the 10-K says difficulties “have adversely impacted” its ability to realise the benefits of the Sierra Wireless acquisition.

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 filing rules out the obvious alternative in its own words. Item 1's Patents and Licenses paragraph says the Company 'does not consider any single patent, trademark, copyright, trade secret, proprietary technology, technical data, business process or any other confidential information (or any related group of any such items) to be of material importance to any segment or to the business as a whole', and the matching risk factor is blunter: 'we do not believe that our business is materially dependent on a single intellectual property right or any group of them. In our opinion, engineering, production skills and experience are more responsible for our market position than our patents and/or licenses.' That is a company disclaiming an IP moat. Where the 10-K does locate durability is the installed equipment and the channel wrapped around it. The overview frames the entire growth plan that way - 'As an industry leader with an extensive global install base, our growth strategy includes expanding recurring revenue through services and rental options' - the principal products and services table carries 'Service agreements', 'Repair and maintenance services', 'Parts and supplies (aftermarket and OEM)' and 'Rental services' alongside the equipment itself, the Distribution paragraph puts U.S. sales through Trane's own 'branch sales offices, distributors and dealers across the country' and non-U.S. sales through 'numerous subsidiary sales and service companies with a supporting chain of distributors throughout the world', and the accounting policy confirms the contracts are multi-period: 'For extended warranties and long-term service agreements, revenue for these distinct performance obligations are recognized over time on a straight-line basis over the respective contract term.' Long-lived equipment serviced under term agreements by the manufacturer's own branches is the asset this filing keeps pointing at, which is why the moat is read as an installed-base tie rather than a patent estate.

The defensible assets the 10-K describes are intellectual: the LoRa® radio technology, analog and mixed-signal design expertise - “The development of IP and the resulting proprietary products is a critical success factor for us” - and 303 U.S. and 541 foreign patents. The filing itself discounts the patent part (“we do not believe they create definitive competitive barriers to entry”), which leaves the moat in proprietary technology and scarce design know-how rather than in scale or lock-in: Semtech outsources most manufacturing, sold 74% of fiscal 2026 net sales through independent distributors, and its customer agreements “do not require them to purchase a minimum quantity of our products”.

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 company's own claim is comparative but never exclusive: 'We are one of the leading manufacturers in the world of HVAC systems and services and transport temperature control products and services' - one of, with no rank, no share figure and no competitor named anywhere in the filing. Competitive Conditions sets that against 'well-established regional or specialized competitors, as well as larger U.S. and non-U.S. corporations or divisions of larger companies', and the risk factors add that Trane competes 'with large companies and with smaller, local operators who may have customer, regulatory or economic advantages in the geographies in which they are located'. The scale behind the claim is substantial and disclosed - $21,321.9 million of 2025 net revenues, products sold in approximately 100 countries, backlog of $7,769.4 million - but the 10-K never asserts the top position in any market it serves.

LoRa, the technology Semtech owns, leads outside China; elsewhere Semtech is contesting the front rank. IoT Analytics’ March 21, 2024 release states “When excluding all LPWAN data from China, LoRa has the leading share of global LPWAN connections at 41%—more than double NB-IoT’s share”, though “Globally, NB-IoT has the largest share of LPWAN connections at approximately 54%” and “LoRa’s share of LPWAN connections is decreasing”. In data-center optics, management said on the fiscal Q2 2027 call (TradingKey machine transcript, https://www.tradingkey.com/news/transcripts/262131465-tradingkey) that at “800 gig, we had the market share about 18%. So over the 2 years, we have grown the market share well over 50% for 800 gig”, a company figure; an independent September 2024 newsletter (Deep Fundamental) had instead named Marvell and MACOM “the dominant players” in drivers and TIAs and said Semtech “has struggled to keep pace since the transition to 200G”. A third-party lead measured at the technology level rather than as Semtech’s own share, a company-reported share that the only independent view contradicts, and no ranking for its other lines do not evidence co-leadership, so the band is fast follower.

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.

Price is a separately disclosed component of growth in this filing and it is positive: of the 7.5% increase in 2025 net revenues, the company's bridge assigns 3.0% to pricing against 3.2% volume, 0.8% acquisitions and 0.5% currency, and gross margin rose 50 basis points to 36.2% 'primarily due to gross productivity and price realization, partially offset by inflation'. In the Americas the price component was 3.8% of an 8.0% revenue increase, and that segment's adjusted EBITDA margin rose 70 basis points to 21.6% 'primarily due to price realization and gross productivity, partially offset by inflation and continued business reinvestment'. What holds the band below strong is in the same bridge and the same risk factors: EMEA pricing was (0.3)% and its segment margin fell 150 basis points to 18.3%; Asia Pacific pricing was 0.4% on organic revenue down 2.5%; consolidation and new entrants 'could result in increased competition and pricing pressures'; and 'in the event there is deflation, we may experience pressure from our customers to reduce prices.' Price that sticks in the Americas, disappears in EMEA and is disclaimed as durable in the risk factors is moderate rather than strong.

The 10-K describes a market where prices fall: “In the past, we have reduced the average selling prices of our products in anticipation of future competitive pricing pressures”, and Semtech’s products “are typically differentiated in performance but are priced competitively”. Margins have nonetheless climbed with the data-center mix: the fiscal Q2 2027 release (https://www.sec.gov/Archives/edgar/data/0000088941/000008894126000028/smtc-07262026x8k991.htm) reports GAAP gross margin of 53.8% against 52.1% a year earlier and guides fiscal Q3 adjusted gross margin to 58.3% +/- 100 bps, or 63.9% excluding the business held for sale. The release does not separate price from mix.

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.

Trane sits on the facility side of the AI build-out rather than in the compute stack. Its FY2025 10-K lists 'Data center HVAC systems', 'Data center liquid cooling solutions', 'Data center facility controls' and 'Data center services' among its principal products and services, alongside 'Thermal energy storage' and 'Smart and AI-enabled services'. Those four entries are the only occurrences of the phrase in the entire filing: there is no data center revenue figure, no ranking, no named competitor and no separate reporting - segment disclosure stops at Americas, EMEA and Asia Pacific, and the MD&A attributes the Americas' 7.4% organic growth to 'realization of price increases and higher volumes led by strong demand within our Commercial HVAC business' without naming an end market.

Semtech sells mostly through independent distributors (74% of fiscal 2026 net sales) to OEMs. In AI data centers its FiberEdge and CopperEdge parts go into the optical transceivers and active copper cables that module and cable makers build, and the 10-K says hyperscale cloud providers “are generally our indirect customers”. Two customers took 14% and 11% of fiscal 2026 net sales, and customers in China (including Hong Kong) 47%.

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.
