The order book is still compounding; what re-priced was the assumption that AI memory demand never pauses. [Technoprobe](https://theinference.org/markets/companies/technoprobe), the Italian maker of the probe cards that test memory chips before they ship, [fell 10.3% on October 15, 2026, the worst stock on Milan's FTSE MIB index](https://www.ilsole24ore.com/art/tecnologici-globali-caduta-libera-milano-peggiore-technoprobe-AJYd2SkB), and lost more than 15% across two sessions, to €26.5 [1][2][3]. The shares [had climbed from about €9 in the summer of 2025 to a June peak above €37](https://www.milanofinanza.it/news/technoprobe-ad-alta-quota-come-l-ai-ha-reso-gigante-l-azienda-nel-testing-dei-chip-anche-a-piazza-affari-202610161902301037) [3]. The trigger sat far from its factories: US inflation of 3.7% revived fear of rate hikes, and doubt about the debt behind AI data centers swept chip stocks worldwide [2][1]. What re-priced was the assumption underneath the shares, that AI memory demand never pauses. *Chart: **From about €9 to a June peak above €37, then a two-day fall to €26.5** Line chart of Technoprobe's share price at three points: about €9 in the summer of 2025, above €37 at the June 2026 peak, and €26.5 after the 15-16 October 2026 selloff.* *Three dated points, not a daily series: about €9 in summer 2025, a June 2026 peak above €37 (plotted at €37), and €26.5 at the close after two sessions of selling.

A probe card is the custom electromechanical interface whose contacts touch a chip while it is still on the silicon wafer and connect it to a tester that checks whether it works; one card can carry more than 50,000 contacts, and each card is built for a single chip design [4]. The more advanced the memory the buildout demands, the more validation work lands on [Technoprobe](https://www.technoprobe.com/technologies-and-products/what-is-a-probe-card)'s order book [3]. ![A cantilever probe card, a hand-sized board with gold traces fanning out to a ring of fine contact needles around a central window](https://storage.googleapis.com/theinference-public/img/bc7252864362e1f1.jpg) *A cantilever probe card, the hand-sized board whose contacts touch a wafer's dies while a tester checks whether each chip works. Older cards carry dozens of needles; cards for advanced memory carry tens of thousands of contacts. (Ajoones)* ## The books delivered what the chain promised First-half 2026 revenue reached €464 million, 42% more than a year earlier [3]. EBITDA, earnings before interest, tax, depreciation and amortization, doubled to €206 million, with the margin up from 32% to 44% [3]. Net profit rose to €143 million from €34 million [3]. Management lifted 2026 guidance and set a 2027 target that implies revenue more than doubling in two years, at a 46–48% EBITDA margin, and the balance sheet can fund it: no debt and €700 million of cash [3]. *Chart: **Revenue is guided to more than double between 2025 and 2027** Column chart of Technoprobe revenue: €540M in 2024, €628M in 2025, guided to about €1,050M in 2026 and targeted at €1,600M in 2027.* *Reported revenue for 2024 and 2025; 2026 is management guidance (midpoint of the €1.0–1.1 billion range); 2027 is the company target. Euros, millions. Source: MilanoFinanza. [3]* ## The repricing came from the cost of money The sell-off began with that inflation print, which brought rate-hike fear back into the market [2]. Higher rates attack the debt that finances AI data centers, and the market reads that stress through [CoreWeave](https://theinference.org/markets/companies/coreweave), the debt-heavy AI data-center operator, [whose bonds due in 2032 have slid to 78 cents on the dollar](https://finance.yahoo.com/markets/stocks/articles/sk-hynix-sinks-ai-stocks-173800193.html) [7]. The memory makers upstream were hit harder still: [SK hynix](https://theinference.org/markets/companies/sk-hynix) and Samsung have each lost more than half from their June highs [6]. ## Sold-out memory trades at two to three times earnings Record results have stopped moving prices. [TSMC](https://theinference.org/markets/companies/tsmc), the world's largest contract chipmaker, [beat estimates on revenue and profit](https://theinference.org/article/tsmc-s-record-quarter-says-the-ai-bottleneck-is-now-the-bond-market), and [Anthropic](https://theinference.org/markets/companies/anthropic), the AI lab, booked about $16.8 billion of quarterly revenue, yet chip stocks fell anyway [1][2]. The constraint has shifted from production capacity to financing costs: [memory is effectively sold out through 2027](https://www.msn.com/en-us/technology/tech-companies/sold-out-chips-falling-stocks-why-wall-street-is-suddenly-nervous-about-ai-s-memory-boom/ar-AA2emVIX), and the companies that make it trade at two to three times forecast earnings [5][6]. ## A thin float carries the whole repricing T Plus, the holding company of the founding Crippa family, controls just over half the capital and nearly two-thirds of the votes, and [Teradyne](https://theinference.org/markets/companies/teradyne), the US test-equipment maker, holds another 10% [3]. Market-wide judgments about AI therefore land on a small traded float, which is how a stock up more than 220% in twelve months can lose a tenth in a day [2][3]. Before the fall it traded at about 66 times expected 2026 earnings, against below 30 for [Nvidia](https://theinference.org/markets/companies/nvidia), the AI trade's flagship [3]. The buyer at that price is underwriting one specific claim: that the compounding runs on without a pause, long enough for earnings to grow into the multiple. *Chart: **Technoprobe traded at more than twice Nvidia's forward multiple** Bar chart of forward price-to-earnings multiples: Technoprobe about 66 times expected 2026 earnings, Nvidia below 30 times, and memory makers two to three times.* *Forward price-to-earnings on expected 2026 earnings, before the fall: Technoprobe about 66 times (MilanoFinanza); Nvidia below 30 (plotted at 30); memory makers two to three times (plotted at the 2.5 midpoint; Benzinga via MSN and Seeking Alpha). [3][5][6]* ## Rates, not probe engineering, will settle this bet The company earns its growth: it closes the gap between fabricated memory and shippable chips, work the AI buildout cannot skip [4]. The bet at 66 times is a different claim, and it will be settled by interest rates and AI balance sheets rather than by probe engineering. The next marker is close: SK hynix, the South Korean memory maker, [gives its fourth-quarter outlook on October 28](https://seekingalpha.com/news/4653899-bofa-says-memory-chip-stock-selloff-looks-overdone) [6]. ## Takeaway The business is not the bet: revenue, margins and net cash are still compounding, but 66 times forward earnings priced AI memory demand as if it never pauses, and one US inflation print was enough to test that. ## Sources 1.
