On May 29, 2001, Mitel Corporation unveiled “Zarlink Semiconductor” as the intended identity for the semiconductor business left after a major corporate separation. This was not a simple rename of the communications-equipment company: the communications-systems operation acquired the Mitel name, while the remaining chip business pursued a focused communications-semiconductor strategy. The announcement also made clear that the formal corporate-name change still required shareholder approval.
What “Mitel becomes Zarlink” actually meant
The old Mitel Corporation was being divided into two successor businesses:
- Zarlink Semiconductor: the semiconductor operation retained by the predecessor Mitel corporation and repositioned as a communications-chip specialist.
- Mitel Networks: the separated communications-systems business, which acquired the Mitel name and most of that operation’s assets and subsidiaries.
That identity swap is the key to understanding the 2001 announcement. Mitel Networks did not change its name to Zarlink. Instead, the systems business took the familiar Mitel identity, while the semiconductor successor adopted a new one.
Mitel Networks’ later SEC filings describe transactions completed on February 16 and March 27, 2001. They say the new company acquired the Mitel name and substantially all of the communications-systems assets and subsidiaries from Zarlink, formerly Mitel Corporation. Canadian real estate and certain intellectual-property assets were excluded or handled through separate arrangements. The later Form 20-F describes the transaction structure.

The chronology of the separation and name announcement
| Date | What happened |
|---|---|
| January 12, 2001 | Mitel Networks was incorporated in Canada by Zarlink, formerly Mitel Corporation, to reorganize the communications-systems division before its sale. |
| February 16, 2001 | Mitel Networks acquired the Mitel name and substantially all of the communications-systems business’s assets and subsidiaries, subject to exclusions and related agreements. |
| March 27, 2001 | A related transaction completed additional parts of the reorganization. |
| May 2001 | Mitel announced a technology and manufacturing agreement with IBM involving PowerPC processor cores and IBM’s 0.18-micron copper process for digital-TV ICs. |
| May 29, 2001 | Mitel unveiled “Zarlink Semiconductor” as the planned identity for the remaining communications-chip company. |
| July 2001, planned | Shareholders were expected to vote on the formal corporate-name change at the annual meeting. |
The May 29 announcement therefore came after the operating-business transfer had been organized, but before the new corporate name was fully effective under the approval process described at the time.
Why Mitel pursued a pure-play semiconductor strategy
The strategy was to turn the remaining company into a pure-play communications-chip supplier rather than a mixed systems-and-semiconductor group. Management presented a narrower business that could concentrate research, product development and capital on communications integrated circuits.
The announced product emphasis covered:
- wired communications ICs;
- wireless communications ICs;
- optical-networking ICs;
- digital-television integrated circuits; and
- specialized ultra-low-power chipsets for medical applications.
The rationale was strategic focus: investors and customers could evaluate the company as a semiconductor specialist, while engineers could target communications markets that required high-performance, mixed-signal or very-low-power devices. The trade-off was greater exposure to the semiconductor cycle and less diversification than a company combining chips with communications systems.

The financial backdrop was unusually difficult
The rebranding was announced during the severe semiconductor downturn of 2001. The contemporary EE Times report said Mitel had announced a $190.6 million charge, planned to reduce its workforce by 430 employees, or 17%, and reported a fiscal fourth-quarter net loss of $202 million on revenue of $81.1 million for the quarter ended March 31, 2001. In the comparable prior-year quarter, it had reported net income of $20.5 million on revenue of $113.7 million. These were the figures reported in May 2001, not a later restatement. EE Times’ contemporaneous report provides the announcement context and figures.
A pure-play structure could make the business easier to understand, but it did not remove the immediate pressure from falling demand, restructuring costs and reduced revenue.
What Zarlink intended to build and sell
Communications and networking chips
Zarlink’s intended markets included wired telecommunications, wireless communications and optical networking. Those areas covered the infrastructure layer of communications rather than consumer electronics in general.
Rank #3
Digital television
The IBM agreement announced earlier in May 2001 was described as a technology and manufacturing pact. It was intended to provide access to IBM PowerPC processor cores and IBM’s 0.18-micron copper process for digital-TV ICs. It was not an acquisition or merger, and the announcement did not guarantee a commercial product launch.

The company also highlighted specialized chipsets for medical applications where extremely low power consumption was important. This was a targeted application area alongside the larger communications markets.
What the name “Zarlink” was supposed to convey
Company officials said “Zarlink” was intended to mean “leader in connectivity.” They described the name as combining an element derived from the Latin word Caesar, associated by the company with power or authority, with the English word “link.” That is the company’s explanation of the branding, rather than an independently established linguistic definition.

Leadership and reported scale at launch
The executive associated with the May 2001 launch was Patrick J. Brockett, identified as president and CEO. He had joined from National Semiconductor, where he had spent 22 years and most recently led the Analog and Wireless Group as executive vice president and general manager.
According to the company figures reported by EE Times, the planned Zarlink organization had approximately:

- more than 3,000 customers in over 100 countries; and
- major customers including Nortel, Lucent, Cisco, Motorola and Ericsson.
These were company-reported figures at the time of the announcement and should not be treated as independently audited or directly comparable with later Zarlink headcounts and customer totals.

Was the name change legally complete on May 29?
No—not on the evidence of the announcement itself. Mitel promoted and unveiled the Zarlink identity on May 29, but said financial reports would continue to be filed as Mitel Corp. and that the shares would continue trading on the New York and Toronto stock exchanges under the MLT ticker. The formal corporate-name change required shareholder approval, with a vote planned for the July 2001 annual meeting.
The precise approval date and outcome are not established by the contemporary announcement cited here. The careful description is therefore: Mitel announced the Zarlink identity in May 2001, while the formal name change remained subject to shareholder approval.
The separation was not operationally clean
Although the businesses became separate successors, later Mitel Networks filings show continuing commercial and legal links. The arrangements included:

- a semiconductor-component supply agreement under which Zarlink supplied components to Mitel Networks;
- intellectual-property licenses from Zarlink to Mitel Networks;
- rights governing retained semiconductor-related technology; and
- noncompetition and nonsolicitation provisions between the businesses.
Zarlink also retained a 10% ownership position in Mitel Networks after the transaction, according to a later Mitel Networks filing. These arrangements explain why the split should not be portrayed as two companies with no continuing relationship. The communications-systems successor depended on the semiconductor successor for certain components and technology even after taking the Mitel name. A later Form 20-F details the ownership and transaction arrangements. Another Form 20-F describes the supply, licensing and related agreements.
What happened to Zarlink afterward
Zarlink continued as an independent semiconductor company for years. Its independent corporate life ended when Microsemi moved to acquire it. Microsemi’s 2011 tender-offer filing described an offer of C$3.35 per Zarlink share. A later Microsemi filing states that the acquisition was completed during the quarter ended January 1, 2012. The tender-offer filing records the C$3.35 offer. The subsequent filing records completion in that quarter.
Quick Recap
Common mistakes when describing the 2001 event
- “Mitel Networks changed its name to Zarlink.” The communications-systems business acquired the Mitel name; the semiconductor successor adopted Zarlink.
- “The legal name changed on May 29.” The announcement said shareholder approval was still required.
- “Zarlink was a general-purpose chip company.” Its announced focus was communications and specialized application ICs.
- “The IBM deal was an acquisition.” It was described as a technology and manufacturing agreement.
- “The split ended all ties.” Supply, intellectual-property, ownership and noncompetition arrangements continued between the successors.
- “Zarlink and modern Mitel are the same company.” They became separate successor businesses after the 2001 restructuring.
