onsemi agreed on 2 November to acquire Ferric, a maker of integrated voltage regulators for AI processors, for $600 million in cash at closing plus up to $175 million more tied to revenue milestones, according to its announcement and an 8-K filed with the SEC. The same day it reported third-quarter revenue of $1.722 billion, up 11% year over year, and its 10-Q put AI data center revenue at $180.2 million, up 175% from $65.6 million a year earlier.
By our arithmetic from the 10-Q, AI data centers supplied $114.6 million of onsemi’s $171.4 million year-over-year revenue increase, or 67%, while making up 10.5% of revenue, up from 4.2%. It is the first quarterly filing we checked that lists AI data center as its own end market: the second-quarter 10-Q folded it into “Other”.

The key insight: By our arithmetic from onsemi’s 10-Q, AI data center revenue of $180.2 million supplied $114.6 million, or 67%, of the company’s $171.4 million year-over-year revenue increase in the third quarter, reported the same day it agreed to pay $600 million in cash for Ferric.
onsemi describes Ferric as an innovator in integrated voltage regulator (IVR) technology. According to the release, Ferric’s design “integrates the power controller, FETs, inductors and capacitors into a single compact package”, which onsemi says reduces board area by 50-70% compared with conventional discrete voltage regulators while delivering more power closer to the processor.
The release says the industry is moving voltage regulation closer to the processor and that IVRs are the next step, “integrating power conversion directly into the processor package or substrate”. Ferric brings a portfolio of more than 40 patents, and approximately 50 employees, primarily in New York and Silicon Valley, are expected to join onsemi.
Chief executive Hassane El-Khoury said: “The rapid growth of AI is reshaping the requirements for power delivery to increasingly capable and power-intensive processors.” Ferric founder and chief executive Noah Sturcken said the company “was founded to rethink how power is delivered at the point of compute”.
With the deal, onsemi raised its 2030 AI data center revenue target by $500 million to greater than $3 billion, “with acceleration thereafter”, according to the release.
Change in onsemi’s quarterly revenue by end market, third quarter of 2026 against the third quarter of 2025, in $ million, from the end-market table in its 10-Q filed on 2 November 2026. AI data center revenue rose from $65.6 million to $180.2 million; the changes and the 67% share of the $171.4 million total increase are our arithmetic.
The Terms in the Merger Agreement
The 8-K says Ferric’s securityholders will receive $600.0 million in cash, “subject to customary purchase price adjustments for Ferric’s cash, indebtedness, transaction costs and working capital”. They can also receive up to $175.0 million in cash on specified revenue milestones. onsemi says the deal will be funded with cash on hand and expects “no meaningful near-term financial impact”.
The merger agreement, filed as Exhibit 2.1, sets the earn-out’s Measurement Date at 31 December 2029. The full $175 million is paid if revenue from Ferric’s products over any four consecutive calendar quarters by then reaches a threshold; otherwise the payment is pro rata to revenue above a separate, redacted threshold in the four quarters ending on that date. The dollar thresholds are redacted as [***] in the filed copy. The revenue that counts includes Ferric’s products sold inside modules for voltage core (Vcore) applications.
Closing requires the expiry or early termination of the Hart-Scott-Rodino antitrust waiting period. The 8-K says onsemi expects the merger to close in the fourth quarter of 2026. By our arithmetic, the $600 million upfront equals about $12 million for each of the roughly 50 employees expected to join, and 13.7% of the $4.368 billion of cash, cash equivalents and short-term investments onsemi held at the end of the quarter.
What onsemi Reported for the Third Quarter
For the quarter ended 2 October 2026, onsemi reported GAAP gross margin of 41.4% and non-GAAP gross margin of 41.2%, GAAP operating margin of 22.0% and non-GAAP operating margin of 23.2%. GAAP diluted earnings per share were $0.79 and non-GAAP $0.90. Cash from operations rose 23% to $516 million and free cash flow 31% to $489 million, 28% of revenue.
El-Khoury said in the results release: “Our third quarter revenue, gross margin and earnings per share exceeded the midpoint of our guidance, while AI data center revenue grew 39% sequentially and 175% year-over-year.”
By end market, the 10-Q shows automotive revenue of $776.7 million against $787.3 million a year earlier, industrial $466.8 million against $426.3 million, and other $298.6 million against $271.7 million. By segment, the Power Solutions Group grew 21% to $889.9 million, while the Analog and Mixed-Signal Group and the Intelligent Sensing Group each grew 2%.
For the first nine months of 2026, AI data center revenue was $413.2 million against $179.0 million, up 131%, by our arithmetic. In its second-quarter release in August, El-Khoury said of AI data center: “we now expect revenue to more than double in 2026”.
How the Quarter Compares With onsemi’s Own Guidance
In August onsemi guided third-quarter revenue to between $1.650 billion and $1.750 billion, non-GAAP gross margin to 40.0% to 42.0% and non-GAAP diluted earnings per share to $0.81 to $0.93. Revenue of $1.722 billion came in $22.3 million above the midpoint of that range, by our arithmetic; the 41.2% margin and $0.90 per share were also above the midpoints.
For the fourth quarter, onsemi guided revenue to between $1.715 billion and $1.815 billion, non-GAAP gross margin to 41.5% to 43.5% and non-GAAP diluted earnings per share to $0.95 to $1.07. The $1.765 billion midpoint is 15.4% above fourth-quarter 2025 revenue of $1.530 billion, which we derived from the 2025 10-K and the third-quarter 2025 10-Q.
Set against the new 2030 target, third-quarter AI data center revenue multiplied by four comes to about $721 million a year, and $3 billion is about 4.2 times that, by our arithmetic. That is a comparison of the target with the current quarter, not a forecast.
Two Other Deals in the Filings
The results release also lists revised terms for onsemi’s planned acquisition of Synaptics, “for approximately $5.7 billion in cash compared to $7 billion in stock for the prior agreement”. The 10-Q puts the amended consideration at $123.00 per Synaptics share in cash and says the transaction is expected to close in mid-2027. We covered the amended Synaptics deal on 1 October.
The 10-Q also reports that on 5 October onsemi completed the acquisition of Silver Atena GmbH, which it says adds systems engineering and application expertise, for $52.2 million in cash.
What the Risk Factors Say
The 10-Q states that there have been no material changes from the risk factors in the 2025 10-K, “other than the addition of the following risk factors”, all of them about the Synaptics transaction. The restated heading on Synaptics’ debt now reads that the treatment of that debt “may involve repayment by us of substantial indebtedness”; in the second-quarter 10-Q it read “may involve repayment or assumption by us of substantial indebtedness” and ended “and could result in dilution to our stockholders”.
The second-quarter 10-Q was filed in August, before the 1 October switch to an all-cash offer. The risk factor section does not mention Ferric.
As we read it, the business lever in these filings is content per AI processor: onsemi already describes a portfolio covering power “from grid to core”, and Ferric’s regulators, in onsemi’s description, integrate power conversion into the processor package or substrate, with an earn-out paid only on revenue from those products.
The Structural Read
As we read it, the earn-out shifts part of the price onto Ferric’s future sales: of the up to $775 million, $175 million, or 22.6% by our arithmetic, is paid only on revenue from Ferric’s products by the end of 2029.
As we read it, the new end-market line shows where the growth sits: automotive, onsemi’s largest end market at $776.7 million, fell $10.6 million year over year, while AI data center rose $114.6 million.
As we read it, the price is large against the business it feeds: the $600 million upfront is about 3.3 times onsemi’s third-quarter AI data center revenue of $180.2 million, by our arithmetic.

“We believe integrated power architectures will play an increasingly important role in the future of AI data centers.”
Three Implications
FOR AI PROCESSOR MAKERS onsemi says Ferric’s IVR reduces board area by 50-70% compared with discrete voltage regulators, so that customers can dedicate a greater share of system power to AI compute.
FOR POWER-CHIP RIVALS onsemi’s Power Solutions Group grew 21% year over year to $889.9 million in the quarter, and the Ferric deal adds more than 40 patents and approximately 50 employees, according to onsemi.
FOR ONSEMI SHAREHOLDERS The Ferric deal is funded with cash on hand, and the amended Synaptics deal is about $5.7 billion in cash, against $4.368 billion of cash, cash equivalents and short-term investments at quarter-end, by our arithmetic.
The Business Engineer Lens
This story maps onto the Business Engineer framework The AI Supercycle.
The framework puts it this way: “Each layer is constrained by the one below it.”
As we read it, onsemi’s filings place it at the bottom of that stack, in the power delivered to each processor. The framework was published in June 2026 and does not discuss onsemi or Ferric.
The filings do not disclose Ferric’s revenue, the earn-out revenue thresholds, which are redacted, or the customers Ferric supplies. onsemi’s 2030 target and its board-area and power claims are the company’s statements and we did not test them. We did not listen to the earnings call or read the investor presentation. Our quarterly figures for AI data center revenue come from the third-quarter 10-Q, which restates the year-earlier quarter; earlier filings we checked did not show it separately.
The 67%, the share of revenue, the per-employee figure and the run-rate comparison are our arithmetic, not company statements. We did not contact onsemi or Ferric.
This Week In The AI Supercycle
Anthropic’s Reality Check, The Capital Squeeze, & The New World Order
This week’s issue: for two years the AI build-out was priced as a growth story. This week it started being priced as a credit story.
onsemi says it agreed to pay $600 million in cash for Ferric, plus up to $175 million on revenue milestones measured through 2029, for integrated voltage regulators that, in onsemi’s description, put power conversion into the processor package or substrate. In the same filings its AI data center revenue reached $180.2 million, up 175%, and by our arithmetic supplied 67% of its year-over-year growth. It raised its 2030 AI data center target to more than $3 billion.
