The $80 Billion Hiding in Plain Sight
In the spring of 2024, as the world convulsed over which companies would capture the value of artificial intelligence, a manufacturer of connectors — small, unglamorous electromechanical components that join cables to circuit boards — crossed $80 billion in market capitalization. Amphenol Corporation, headquartered not in Silicon Valley but in Wallingford, Connecticut, a town of 45,000 people best known for its proximity to Interstate 91, had quietly become one of the most valuable industrial companies on the planet. More valuable than Deere & Company. More valuable than Honeywell. Worth roughly twice as much as the entire publicly traded U.S. airline industry combined.
The paradox is instructive. Amphenol makes components that most technology executives could not pick out of a lineup — circular connectors, fiber optic assemblies, high-speed backplane interconnects, RF adapters, sensors, antennas — sold in quantities so vast and at price points so granular that the company's average transaction value is nearly invisible. No consumer has ever bought an Amphenol product on purpose. No analyst conference opens with a keynote about interconnect architecture. Yet here was a company generating north of $14 billion in annual revenue, operating at margins that would make software executives squint, and compounding shareholder returns at a rate that turned a $10,000 investment in 1999 into something approaching $1.5 million by early 2025. The trick, if you could call decades of disciplined execution a trick, was that Amphenol had figured out how to be essential without being visible — to occupy the connective tissue of virtually every electronic system on Earth while remaining too diversified, too decentralized, and too relentlessly profitable to attract the regulatory scrutiny or competitive fury that visibility invites.
This is a company that doesn't build the data center. It builds the thing that makes the data center work.

Connectors as Destiny
To understand Amphenol, you first have to understand the connector — an object so mundane it resists narrative. A connector is a device that joins electrical circuits together. It is, in the taxonomy of electronics, a passive component: it doesn't compute, doesn't store data, doesn't amplify signals. It transmits. The connector's value proposition is reliability at scale. In a fighter jet, a single failed connector can down a $100 million aircraft. In a hyperscale data center, a faulty high-speed interconnect can degrade the performance of an AI training cluster worth hundreds of millions. The failure modes are catastrophic and the replacement costs absurd relative to the component price. This asymmetry — a $3 part protecting a $3 million system — is the economic engine of the entire interconnect industry.
The global connector market was approximately $80–90 billion in 2024, growing at a mid-single-digit compound rate that has persisted, with cyclical interruptions, for decades. Connectors are one of the few electronic component categories that has resisted commoditization. Unlike resistors or capacitors, where standardization has crushed margins, connectors remain stubbornly application-specific. A connector designed for an undersea oil rig shares almost nothing with a connector designed for a smartphone antenna module. The qualification cycles are long — eighteen months to three years for military applications — and the switching costs, while not individually enormous, compound across thousands of part numbers in a single customer's bill of materials. A procurement manager at Lockheed Martin or Cisco doesn't casually swap connector suppliers the way one might change capacitor vendors. The requalification burden, the tooling costs, the risk of field failure — it all conspires to keep incumbents locked in.
Amphenol understood this earlier and more completely than anyone.
A Company Born from War, Rebuilt by Immigrants
The company's origins are rooted in wartime industrialization. Founded in 1932 in Chicago by Arthur Schmitt as American Phenolic Corporation — a manufacturer of tube sockets and connectors using phenolic resin — the company's early trajectory was shaped by the same mobilization that built the American defense-industrial base. World War II created explosive demand for ruggedized electrical connectors, and American Phenolic, rebranded as Amphenol in 1955, became a primary supplier to the U.S. military. The circular MIL-spec connectors that Amphenol pioneered in the 1940s became de facto standards, and many remain in production, with iterative upgrades, eighty years later. Standards, once established, have a gravitational pull that outlasts the engineers who wrote them.
But the company that exists today — the decentralized, acquisitive, margin-obsessed machine — is really the creation of two people, neither of them born in the United States.
The first was Martin Loeffler, an Austrian-born engineer who joined Amphenol in the 1960s and rose through the ranks of its international operations. Loeffler understood something that most American industrial managers of his era did not: that connectors were a global business, and that manufacturing proximity to customers — not centralized scale — was the decisive competitive advantage. Under his influence, Amphenol built a network of factories across Europe and Asia at a time when most competitors were still shipping everything from domestic plants. The logic was simple but unorthodox for the period. Connectors are heavy relative to their value, expensive to ship, and subject to local certification requirements. A factory in Shenzhen could serve Chinese OEMs with shorter lead times, lower logistics costs, and a local engineering team that spoke the customer's language — literally and figuratively.
The second, and far more consequential, figure was R. Adam Norwitt, who became CEO in 2008 at the age of 37. Norwitt — born in New York, educated at Harvard (BA in classical languages) and Harvard Law School, a former corporate lawyer at Davis Polk who joined Amphenol in 2000 essentially on a whim — is the most important leader in the company's history and one of the least discussed CEOs in American industry. He is also, by any quantitative measure, among the most successful. Under Norwitt's tenure, Amphenol's revenue has grown from approximately $3.2 billion to over $15 billion, its market capitalization from roughly $8 billion to above $80 billion, and its operating margins have expanded from the high teens to the low twenties. He achieved this while executing more than sixty acquisitions, maintaining pristine balance sheet discipline, and preserving a management structure so decentralized that Amphenol's corporate headquarters employs barely more than a hundred people.
We don't run our business from the top. We run our business from the general managers who are closest to the customers, closest to the technology, closest to the costs.
Norwitt's background matters. A classics major running a connector company might sound like a punchline, but the fit is oddly precise. Classical languages train the mind to parse complex systems of inflection and syntax — to see structure beneath surface variation. Amphenol's business, which operates across dozens of end markets with tens of thousands of products, requires exactly this: the ability to discern underlying patterns of margin, growth, and competitive position across wildly heterogeneous applications. Norwitt has described the company's philosophy in terms that sound almost Socratic — questioning everything, assuming nothing, decentralizing authority because no central mind can comprehend the full complexity of what the company does.
The Architecture of Decentralization
Amphenol's organizational structure is its most important strategic asset, and the one most frequently misunderstood by analysts who mistake it for a holding company model. It is not a holding company. It is a deeply integrated operating company that has simply pushed virtually all operational authority — pricing, product development, manufacturing, customer relationships — down to the general manager level.
The company operates through more than 130 business units, each run by a general manager with near-complete P&L responsibility. These GMs control their own engineering teams, their own factories, their own sales forces. They set their own prices. They make their own capital expenditure decisions, subject to corporate approval for larger amounts. They are compensated overwhelmingly on the performance of their own unit — operating income growth, return on assets, cash conversion. The system is Darwinian by design: high-performing GMs are promoted rapidly, given more resources, offered acquisition opportunities. Underperformers are counseled, restructured, or replaced. Amphenol's corporate center provides capital allocation, M&A execution, financial reporting, and strategic direction — it does not provide operational management.
The result is an organization that moves with the speed and customer intimacy of 130 small companies while deploying the capital, purchasing power, and global reach of one large one. When a hyperscaler needs a custom high-speed connector for a next-generation GPU rack, the relevant Amphenol business unit can design, prototype, and begin qualification in weeks — not months — because the engineering team sits in the same building as the manufacturing line, reports to the same GM, and has the authority to commit resources without a chain of twenty approvals ascending to Connecticut. When a European automotive OEM needs a sensor assembly qualified to ISO 26262 functional safety standards, a different Amphenol business unit — one with its own automotive-focused engineers, its own test labs, its own relationship with the customer's procurement team — handles the entire process.

| Function | Corporate HQ | Business Unit GM |
|---|
| Capital allocation & M&A | ✓ Primary | Input & integration |
| Pricing decisions | — | ✓ Full authority |
| Product development | Strategic direction | ✓ Execution & roadmap |

This structure is not unique to Amphenol — Danaher, Illinois Tool Works, Berkshire Hathaway's manufacturing subsidiaries all operate versions of it. What is distinctive is the granularity of the decentralization and the ferocity of the performance culture. Amphenol's 130-plus business units are, on average, roughly $100 million in revenue each. That's small enough that a single general manager can truly know every major customer, every key product line, every cost driver. It's large enough to support meaningful engineering investment and manufacturing scale. The sweet spot is not accidental. When an acquired business grows too large, Amphenol has been known to split it into two or three units to maintain the entrepreneurial intensity that size can erode.
The Acquisition Machine
If decentralization is the engine, M&A is the fuel. Amphenol has completed more than sixty acquisitions since 2000, spending an estimated cumulative total exceeding $15 billion. The pace has accelerated: in the 2020s alone, the company closed some of its largest deals, including the $2.0 billion acquisition of the Interconnect Solutions division of MTS Systems (completed in 2021), the approximately $575 million purchase of the RF solutions business from Raycap in 2023, and, most dramatically, a wave of transactions in 2024 that included deals valued at over $2 billion in aggregate.
The acquisition strategy is not opportunistic empire-building. It follows a rigorous, repeatable playbook that Norwitt has described in investor presentations with unusual specificity:
Target profile: Amphenol acquires interconnect and sensor businesses — almost never businesses outside this core — that serve end markets where the company already operates or wishes to enter. The targets must have strong technology positions, defensible customer relationships, and manageable margin profiles. Amphenol does not buy turnarounds. It buys well-run businesses and makes them better.
Valuation discipline: The company targets acquisition multiples in the range of 10–14x trailing EBITDA, well below the 16–20x multiples that private equity buyers routinely pay for industrial businesses of comparable quality. Amphenol can do this because it is usually buying from founders, family owners, or corporate parents who want certainty, speed, and cultural fit — not just the highest price. The company's reputation for preserving acquired management teams and operating autonomy is a genuine competitive advantage in deal-sourcing.
Integration model: Here is where the machine reveals itself. Amphenol does not centralize acquired businesses. It does not strip out the sales team and roll the products into an existing division. Instead, it installs the acquired company as a new business unit within the Amphenol structure, retains the general manager (often the founder or CEO of the target), and immediately subjects the business to Amphenol's financial discipline — monthly P&L reviews, margin targets, cash conversion expectations. The technology and customer relationships stay intact. What changes is the cost structure, the capital allocation rigor, and the growth expectations. Acquired businesses typically see 200–500 basis points of margin improvement within the first two years, not through revenue synergies (Amphenol is skeptical of revenue synergy promises) but through procurement leverage, manufacturing rationalization, and the simple imposition of a culture that does not tolerate cost bloat.
We have a very strong track record of acquiring businesses and improving them, and the way we improve them is not by consolidating them into something bigger. It's by keeping the entrepreneurial spirit of the people who built them and giving them the tools and the expectations to grow profitably.
The cumulative effect is staggering. Each acquisition adds a new node to the network — a new set of customer relationships, a new technology platform, a new geographic footprint — without adding meaningful bureaucratic overhead. The corporate center doesn't grow when Amphenol acquires a business. The general manager count grows by one. The complexity is absorbed at the edge of the organization, not the center.
The Diversification Doctrine
Walk through Amphenol's revenue by end market and the first thing that strikes you is the sheer breadth. No single end market accounts for more than 25% of revenue. No single customer accounts for more than 10%. The company reports across six primary segments: IT Data Communications (including AI and cloud infrastructure), Military & Aerospace, Automotive, Industrial, Mobile Devices, and Broadband Communications. In any given quarter, one or two of these segments may be declining while others are growing, and the portfolio effect smooths the company's aggregate performance to a degree that seems almost suspiciously consistent.
This is not diversification for its own sake. It is diversification as risk management and as an information arbitrage mechanism. Because Amphenol operates deep inside the supply chains of virtually every electronics-intensive industry, its general managers collectively possess a real-time mosaic of demand signals that no single-market company — and arguably no Wall Street analyst — can replicate. When automotive production is weakening in Europe, Amphenol's automotive GMs see it in their order books months before it shows up in Volkswagen's earnings. When a hyperscaler is accelerating data center builds, Amphenol's IT datacom GMs see the purchase orders before the capital expenditure appears in the cloud company's 10-Q. This information doesn't just flow to corporate headquarters for strategic planning purposes — it flows laterally, between business units, enabling cross-selling and technology transfer that a more siloed organization would miss.
📊
Revenue Diversification (FY2024)
Approximate revenue mix by end market
| End Market | FY2024 Revenue (est.) | % of Total | Trend |
|---|
| IT Datacom (incl. AI) | ~$3.8B | ~25% | Accelerating |
| Military & Aerospace | ~$2.7B | ~18% | Steady growth |
| Automotive | ~$2.6B | ~17% | Mixed / content gains |
The automotive segment illustrates the diversification logic particularly well. Amphenol entered automotive connectors seriously through a series of acquisitions in the 2010s, including the 2019 purchase of certain interconnect assets that gave it meaningful positions in electric vehicle powertrain connectors and advanced driver-assistance systems (ADAS) sensor assemblies. The move was counterintuitive at the time — automotive connectors carry lower average margins than military or datacom connectors, and the automotive supply chain is notoriously brutal to its Tier 1 and Tier 2 suppliers. But Norwitt saw that the electrification and digitization of vehicles was structurally increasing the connector content per car — from roughly $100 in a traditional ICE vehicle to $300–600 in a battery electric vehicle — and that this content growth would more than offset the margin pressure. It was a volume-and-mix bet disguised as a diversification play.
Inside the AI Gold Rush
Then came artificial intelligence, and Amphenol found itself, almost by accident of history and preparation, at the center of the largest capital expenditure cycle in the history of technology.
The numbers are disorienting. In 2024, the major hyperscalers — Microsoft, Amazon, Google, Meta, and their Chinese counterparts — collectively spent an estimated $200+ billion on data center infrastructure. A meaningful fraction of that spend flowed through companies like Amphenol, because every GPU server, every network switch, every optical transceiver, every power distribution unit in a modern AI data center requires high-performance interconnects. The specifications are brutal: 112 Gbps per lane, moving to 224 Gbps; signal integrity at nanometer tolerances; thermal performance under 700-watt GPU envelopes; power connectors handling 48-volt distribution architectures that didn't exist five years ago. These are not commodity components. They are precision-engineered systems that require deep co-design with the GPU makers (Nvidia, AMD, custom ASIC teams at Google and Amazon) and the server OEMs (Dell, HPE, Supermicro, and the hyperscaler in-house design teams).
Amphenol's IT datacom segment — which includes AI-related interconnects — grew approximately 40% year-over-year in 2024, making it the fastest-growing and most profitable segment in the company. Norwitt has been characteristically restrained about the AI opportunity, declining to provide AI-specific revenue figures while acknowledging that the company is "extremely well positioned" and that the content opportunity per AI server is "multiples" of what it was in a traditional enterprise server.
What gives Amphenol an advantage here is not just technology — TE Connectivity, Molex, and Samtec all compete fiercely in this space — but the organizational structure described above. When Nvidia needs a new high-speed connector for its next-generation NVLink interconnect, the Amphenol business unit serving that relationship can design, prototype, test, and begin qualification in a compressed timeline because it controls its own engineering resources, its own test equipment, and its own manufacturing capacity. There is no committee. There is no corporate product review board. There is a general manager with the authority, the incentive, and the proximity to the customer to move fast.
We are not going to tell you that we know how big AI will be. What we will tell you is that wherever it goes, Amphenol's technology will be there enabling it.
The Margin Religion
Amphenol's operating margins tell a story of relentless, compound discipline. In 2008, when Norwitt became CEO, adjusted operating margins were approximately 17–18%. By 2024, they had expanded to nearly 22%, despite the addition of lower-margin acquired businesses, despite raw material inflation, despite a global pandemic, and despite the inherent margin pressure of serving automotive and mobile device customers who view their supply chain as a cost center.
How? The answer is not a single lever but a system of interlocking behaviors. First, Amphenol's decentralized structure means that margin management happens at the business unit level, where the general manager can see and control every cost driver. There is no corporate overhead allocation that obscures true profitability. Every GM knows exactly what his or her operating income is, every month, and knows that their compensation and career trajectory depend on it. Second, Amphenol's manufacturing footprint is overwhelmingly in low-cost regions — China, India, Eastern Europe, Mexico, and Southeast Asia — with high-cost facilities maintained only where customer proximity or security clearance requirements demand it. The company's estimated 60% of manufacturing in low-cost regions gives it a structural cost advantage over competitors with heavier North American and Western European footprints. Third, Amphenol is ruthless about pricing. Unlike many industrial companies that accept annual price-downs from automotive or consumer electronics customers as a cost of doing business, Amphenol's GMs are empowered — and expected — to push back, to walk away from low-margin orders, to redesign products for lower cost rather than accept lower price. Norwitt has said, in multiple earnings calls, that Amphenol will "never sacrifice margin for revenue." The record suggests he means it.
The cash conversion cycle reinforces the margin discipline. Amphenol typically converts 100%+ of net income into free cash flow, a ratio that signals not just profitability but working capital efficiency — tight inventory management, rapid receivables collection, and the kind of supplier terms that only accrue to companies with purchasing scale and a reputation for prompt payment.
The TE Connectivity Question
No analysis of Amphenol is complete without reckoning with its principal rival. TE Connectivity, the Swiss-domiciled (originally Tyco Electronics) interconnect giant, is larger than Amphenol by revenue — approximately $16 billion in FY2024 — and competes across nearly every end market Amphenol serves. The two companies are the Coca-Cola and PepsiCo of the connector world, except that neither has ever engaged in anything resembling a price war, and both have been content to grow the market rather than destroy each other's margins.
The differences are instructive. TE is more centralized, more focused on large-volume automotive and industrial applications, and more exposed to the secular growth — and cyclical brutality — of the global auto industry, which accounts for roughly 35% of its revenue. Amphenol is more diversified, more acquisitive, more decentralized, and has historically generated higher operating margins (by 200–400 basis points, depending on the year). TE's scale advantage in automotive gives it pricing power with OEMs that Amphenol cannot always match. Amphenol's agility advantage in datacom and military gives it design-win velocity that TE struggles to replicate.
The competitive dynamic is less war than coexistence. In most end markets, Amphenol and TE are the top two suppliers, and customers deliberately dual-source to avoid dependency on either. The real competitive threats, such as they are, come from below — from Asian manufacturers like Luxshare Precision, JAE Electronics, and Hirose Electric that are climbing the technology ladder in consumer electronics and increasingly in automotive — and from the customers themselves, as hyperscalers invest in custom interconnect solutions designed in-house and manufactured by contract suppliers.
The Quiet Empire of Sensors
One of the least appreciated dimensions of Amphenol's strategy is its steady expansion into sensors — a category that blurs the boundary between passive interconnect and active electronics, and that carries meaningfully higher margins.
Through acquisitions including the 2013 purchase of Advanced Sensors (a GE
Measurement & Control spin-off deal that included the Amphenol Advanced Sensors brand) and the 2016 acquisition of FCI Asia, Amphenol has built a sensor portfolio spanning temperature, pressure, humidity, speed, and position sensing across automotive, industrial, medical, and aerospace applications. Sensors are, in Norwitt's framework, "connectors that think" — they occupy the same physical location in a system (at the interface between the physical and electrical worlds), require the same qualification rigor, and are sold to the same procurement organizations. But they carry higher ASPs, stronger margin profiles, and deeper competitive moats because the calibration and algorithmic intelligence embedded in a sensor assembly is harder to replicate than the physical geometry of a connector.
The sensor market is estimated at approximately $200 billion globally, of which Amphenol captures only a small fraction. The runway is long. And the M&A pipeline — Amphenol explicitly lists sensors as a priority acquisition category — suggests the company intends to run it.
A Culture That Eats Strategy
Spend time with people who have worked at Amphenol — engineers, product managers, general managers — and a remarkably consistent portrait emerges. The culture is intense, performance-oriented to the point of being Spartan, and deeply suspicious of corporate overhead. There are no campus cafeterias, no game rooms, no culture committees. Offices are functional. Travel policies are frugal. The compensation structure is tilted heavily toward variable pay tied to business unit performance. One former general manager described the environment as "the most entrepreneurial thing I've ever experienced inside a large corporation — you run your business like it's your own company, because in every way that matters, it is."
The flip side of this intensity is real. The culture is demanding. Underperformance is addressed quickly. The decentralized structure can create internal competition between business units pursuing overlapping customers. Knowledge sharing, while improving, is less systematic than it would be in a centralized organization. And the general manager model creates a particular kind of talent risk: Amphenol's best GMs are, by design, capable of running independent companies, and competitors and private equity firms know it.
Norwitt manages this tension with a combination of equity incentives (substantial stock ownership is expected at every management level), rapid promotion paths, and a remarkable personal presence. Despite the extreme decentralization, Norwitt personally knows most of the company's general managers, visits dozens of facilities annually, and conducts the monthly operating reviews that are the heartbeat of Amphenol's management rhythm. The paradox — a hyper-decentralized company held together by the personal gravitational pull of a single leader — is not lost on the investment community. Succession planning is the one question Norwitt addresses less directly than any other.
The Private Company That Happens to Be Public
Amphenol behaves, in many respects, like a private company. It does not hold analyst days frequently. Its earnings calls are short and information-dense — Norwitt typically delivers his prepared remarks in under fifteen minutes, answers questions with precision and minimal embellishment, and ends the call as soon as the questions run out. There are no "strategic vision" presentations, no elaborate five-year guidance frameworks, no attempts to manage the narrative beyond the numbers themselves. The quarterly results speak, and Norwitt trusts them to speak clearly enough.
This reticence has costs. Amphenol trades, arguably, at a discount to what its operating performance would command if the company were more aggressive about investor marketing. For much of the 2010s, Amphenol's price-to-earnings multiple lagged significantly behind companies with comparable growth and margin profiles but better-known brands. The AI-driven re-rating of 2023–2024 partially corrected this, as investors belatedly recognized Amphenol's centrality to data center infrastructure, but the company still receives less analyst coverage — and less retail investor attention — than its financials would seem to merit.
Norwitt has indicated, obliquely, that he prefers it this way. An undervalued stock is a tool for accretive acquisitions. A low profile is a moat against regulatory attention. The less the world understands about Amphenol's competitive position, the harder it is for competitors to copy and for customers to negotiate. Visibility, in Amphenol's worldview, is a cost, not a benefit.

The KKR Interregnum
A crucial chapter, rarely examined in sufficient detail: the private equity ownership period that forged the modern Amphenol.
In 1997, KKR acquired Amphenol from Allied Signal (later Honeywell) for approximately $1.5 billion. The purchase was, by KKR's standards, modest — a mid-market industrial carve-out of the kind that private equity firms execute by the dozen. But the impact was transformational. KKR installed new management discipline, pushed the decentralized operating model to its logical extreme, and — critically — attracted a cohort of managers, including the young Adam Norwitt, who were drawn by the entrepreneurial structure and the equity incentives that KKR's ownership made possible.
When Amphenol went public in 1999 at a valuation of approximately $2.5 billion, KKR retained a significant stake and its influence on the board. The private equity DNA — the obsession with returns on capital, the allergy to bureaucracy, the belief that operating leverage matters more than revenue growth — persisted long after KKR's last shares were sold. Norwitt has acknowledged this inheritance explicitly, noting that Amphenol's culture owes a debt to the KKR years that most observers underappreciate.
The parallel to Danaher — which underwent its own private equity-inspired transformation under the Rales brothers — is worth noting. Both companies learned from private equity that the unit of management is the business unit, not the corporation; that incentive alignment is more powerful than strategic direction; and that cash flow, not earnings per share, is the metric that matters. Both became compounding machines. The difference is that Danaher went on to build the Danaher Business System into a codified, exportable operating philosophy. Amphenol never codified its system. It embedded it in its culture, its compensation structure, and the expectations that Norwitt personally enforces in every monthly review. The system is the people.
The Connective Tissue of Everything
Stand back far enough and the pattern resolves. Amphenol has spent nine decades embedding itself in the connective tissue of modernity — the physical layer where electrical signals cross from one subsystem to another, where data moves from chip to board to rack to building to continent. Every secular trend that increases the complexity and density of electronic systems — electrification, autonomy, artificial intelligence, 5G, renewable energy, space exploration, the digitization of industrial processes — increases the demand for interconnects, increases the performance requirements, increases the qualification barriers, and increases the value that accrues to the companies that can engineer and manufacture at that boundary.
The company's position is not invulnerable. Optical interconnects could displace copper in some applications, though Amphenol has hedged this by building a substantial fiber optic connector business. Vertical integration by hyperscalers could pressure margins in the data center. Chinese competitors are investing aggressively in high-performance connectors for domestic consumption. A global recession would hammer the automotive and industrial segments simultaneously.
But the fundamental bet — that the world will continue to electrify, that electronic systems will continue to grow in complexity, and that the interface between those systems will remain a locus of irreducible engineering difficulty — is not a bet on any single technology or any single customer. It is a bet on the trajectory of civilization itself.
On the morning of Amphenol's Q4 2024 earnings call, Norwitt closed his prepared remarks with a figure: the company's book-to-bill ratio stood at 1.08, meaning orders were outpacing revenue — the forward pipeline was accelerating. He moved to questions without pausing. In Wallingford, the snow was falling, and the machine was working.
