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.

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.

FY2026 10-K (filed 2026-03-11): differentiated platform IP — over 10,000 issued patents and pending applications as of 2026-01-31, plus a proven custom ASIC platform leveraging ultra-high-speed SerDes, silicon photonics, co-packaged optics and custom HBM — but Marvell itself calls its markets 'intensely competitive' with 'pricing pressures', notes customers 'have chosen to develop certain semiconductor products internally', and discloses two >=10% customers with the ten largest at 82% of FY2026 net revenue. Real, defensible IP in a concentrated, contestable customer base = narrow, not wide. https://www.sec.gov/Archives/edgar/data/1835632/000183563226000011/mrvl-20260131.htm

Moat type intangibles ip

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”.

cost scale

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".

The moat rests on hard-to-replicate mixed-signal IP: the 10-K describes the custom ASIC platform built on ultra-high-speed SerDes, ARM compute, security, storage, silicon photonics and advanced packaging (die-to-die interconnects, chiplets, CPO, custom HBM), with multiple 5nm designs executed, 3nm in progress and a 2nm platform in development; a secondary switching-cost element comes from multi-year custom design wins co-developed to individual customer specifications. https://www.sec.gov/Archives/edgar/data/1835632/000183563226000011/mrvl-20260131.htm

Leadership fast follower

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.

co 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.

Pricing power moderate

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.

moderate

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.

The 10-K characterizes Marvell's markets as having 'pricing pressures' and intensifying competition (https://www.sec.gov/Archives/edgar/data/1835632/000183563226000011/mrvl-20260131.htm), yet the Q1 FY2027 release reports 52.1% GAAP / 58.9% non-GAAP gross margin on record revenue (https://www.sec.gov/Archives/edgar/data/1835632/000183563226000014/q127_8kx522026ex-991.htm) — differentiated-IP margins, tempered by hyperscaler buyer power.

Summary

Semtech is an analog and mixed-signal chipmaker being reshaped around two franchises. The first is AI data-center connectivity in its Signal Integrity segment - FiberEdge TIAs and drivers for optical transceivers and CopperEdge redrivers for active copper cables - whose net sales the FY2026 10-K reports at $322,608 thousand in fiscal 2026 against $177,033 thousand in fiscal 2024; the March 2026 HieFo acquisition added foundries that make devices for data-center interconnects. The second is LoRa, the long-range, low-power radio that IoT Analytics ranks as the leading LPWAN technology outside China. Around them sit protection devices, sensing and power products, and the IoT Systems business inherited from Sierra Wireless, whose cellular-module unit Semtech has agreed to sell to Compal Electronics for US$62 million (ABI Research, September 9, 2026, https://www.abiresearch.com/market-research/insight/7788486-compal-electronics-takes-semtechs-mantle-t). Momentum is strong: the fiscal Q2 2027 release reports record net sales of $341.9 million, up 33% year over year, and management said data-center revenue hit a record $100 million in the quarter. But the 10-K is frank about limits - rapid ASP erosion, customers that can drop its parts with little notice, 47% of sales to China, competitors that are “much larger and better resourced than we are”, and patents that do not bar entry. Proprietary technology in two growing niches, rather than a locked-in customer base, makes the moat narrow.

EMCOR Group installs and services electrical and mechanical systems in non-residential buildings and plants. Its FY2025 10-K reports revenues of $16.99 billion, approximately 72% from construction operations, approximately 21% from building services and approximately 7% from industrial services, through "approximately 100 operating subsidiaries"; the United Kingdom operations were sold on December 1, 2025. Data centres now drive the construction book: the network and communications market sector was $2,461,883 thousand, or 48%, of electrical construction segment revenue in 2025, against 34% in 2023, and $1,670,355 thousand, or 23%, of mechanical construction segment revenue, against 8% in 2023. Remaining performance obligations were $13.25 billion at the end of 2025, and the Q2 2026 results release (2026-07-30) put them at "a record $17.14 billion, compared to $11.91 billion as of June 30, 2025", with revenue guidance for 2026 raised to $20.00 billion - $20.50 billion. The 10-K's case for an edge is that bids for large work are "often conditioned upon prior experience, technical capability, and financial strength" and require performance bonds, and that EMCOR's balance sheet, bonding, prefabrication and VDC capabilities and safety record "give us an advantage over many of our competitors". The same filing sets the limits: the industry is "highly fragmented and our competition includes thousands of small companies across the United States", "relatively few barriers exist to prevent entry", most revenue comes from "projects requiring competitive bids", some rivals can price "at lower rates than we are currently able to provide", customers' in-house staff compete for building services, and the 10-K warns that if data centre spending "were to decrease, demand for our services could decline as we transition our resources to other sectors". Gross margin rose to 19.3% in 2025 from 19.0% in 2024, which MD&A attributes to "improved revenue mix and excellent project execution". A scale and execution edge on large, bonded projects, re-tested at every bid in an industry with low entry barriers, is a narrow moat.

Marvell is a fabless data-infrastructure silicon supplier whose center of gravity has shifted decisively to the AI data center: the data center end market was $6,100.3M, 74% of FY2026 revenue, up from 40% two fiscal years earlier (FY2026 10-K). Its strongest position is electro-optics — in high-end PAM4 optical DSPs for 400G+ transceivers it holds roughly 60% share on Inphi-inherited SerDes/FEC IP, with Broadcom above 30%, the two together over 90% (36kr, 2026-06-27). In custom AI silicon it is the structural #2 design partner at an estimated 20-25% of the custom AI ASIC design-services market versus Broadcom's ~70%, anchored by AWS Trainium and Microsoft Maia wins (hashrateindex, 2026-05-13). The Q1 FY2027 release (2026-05-27) shows the flywheel turning — record $2.418B revenue (+28% YoY), Q2 guided to $2.7B mid-point (+35% YoY), management citing 'exceptional AI-related bookings' across 800G/1.6T optics, 51.2T switches, CPO/NPO and custom XPU — and the Celestial AI (Photonic Fabric) and XConn (PCIe/CXL switching) acquisitions closed in February 2026 extend the interconnect moat toward scale-up fabrics. The offsets that keep the moat narrow are in Marvell's own filing: intense competition (AMD, Alchip, Astera, Ayar, Broadcom, Credo, GUC, Lightmatter and others), hyperscaler in-housing risk, and heavy customer concentration.

Chain position

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%.

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.

Fabless supplier spanning 'data center core to network edge': it sits between hyperscaler AI compute (custom XPU/XPU-attach ASICs) and the optical layer (PAM4/coherent DSPs, CPO/LPO, DCI, AEC, PCIe retimers), outsourcing fabrication to independent CMOS foundries; the Feb-2026 Celestial AI and XConn acquisitions push it further into scale-up photonic fabric and PCIe/CXL/UALink switching (FY2026 10-K, https://www.sec.gov/Archives/edgar/data/1835632/000183563226000011/mrvl-20260131.htm).
