Applied Micro Circuits Corporation (also known as AppliedMicro, AMCC or APM) was a fabless semiconductor company designing network and embedded Power ISA (including a Power ISA license), and server processor ARM (including an ARMv8-A license), optical transport and storage products.
Key Information
History
[edit]In 2004, AMCC bought assets, IP and engineers concerning the PowerPC 400 microprocessors from IBM for $227 million and began marketing the processors under their own name.[4] The deal also included access to IBM's SoC design methodology and advanced CMOS process technology.
In 2009, AppliedMicro changed their branding from AMCC to AppliedMicro,[5] but still retain the name "Applied Micro Circuits Corporation" officially.
In 2011, AppliedMicro was integral in (co-)developing ARM's first 64 bit-wide AArch64 ISA-extension and became the first company to implement the resulting ARMv8-A architecture with its X-Gene Platform. In November 2012 at ARM TechCon, AppliedMicro demonstrated advanced web search capabilities and the ability to handle big data workloads in an Apache Hadoop software environment with the X-Gene Platform using FPGA emulation. A silicon implementation of X-Gene was first exhibited publicly in June 2013.[6]
In April 2016, information about the forthcoming X-Gene 3 server chips was made available. The release schedule was for the second half of 2017. The company projected an improved performance, over the X-Gene 2, that with allow it to better compete with servers using the x86-64 architecture.[7]
In November 2016, MACOM Technology Solutions announced that they would purchase AppliedMicro.[8] The acquisition was completed on January 26, 2017.[1] MACOM then sold the processor division to the private equity firm The Carlyle Group during October 2017.[9]
Memberships

View on Grokipediafrom Grokipedia
Applied Micro Circuits Corporation (AppliedMicro) was a fabless semiconductor company that designed and developed high-performance silicon solutions for next-generation cloud infrastructure, data centers, and high-speed connectivity products used in communications equipment.[1]
The company was incorporated in California in 1979 and reincorporated in Delaware in 1987, with its headquarters located in Santa Clara, California.[1] Initially focused on application-specific integrated circuits (ASICs), AppliedMicro evolved into a key provider of advanced semiconductors, particularly emphasizing energy-efficient computing and communications technologies for datacenters, telecommunications, enterprise, and consumer applications.[2] Its business was organized into two primary segments: Computing, which included ARM-based processors such as the X-Gene family of 64-bit server-on-a-chip solutions and the HeliX family of embedded processors; and Connectivity, encompassing high-speed interface products like X-Weave for optical transport networks (OTN), Ethernet, and SerDes (serializer/deserializer) technologies supporting data rates up to 100G and beyond.[1]
AppliedMicro's innovations positioned it as a leader in energy-conscious solutions, including leadership in MACsec security for Ethernet and PAM4 modulation for 100G to 400G optical networks, enabling efficient data transmission in cloud and enterprise environments.[3] The company went public on NASDAQ under the ticker AMCC and grew through strategic acquisitions, such as Veloce Technologies in 2012 for $178.5 million to bolster its ARM-based server technology portfolio.[1]
In November 2016, MACOM Technology Solutions Holdings, Inc. announced a definitive agreement to acquire AppliedMicro for approximately $770 million in a combination of cash and stock, valuing shares at $8.36 per share ($3.25 cash plus 0.1089 MACOM shares).[4] The acquisition was completed on January 26, 2017, making AppliedMicro a wholly owned subsidiary of MACOM, with its common stock delisted from NASDAQ.[3] This merger strengthened MACOM's capabilities in optical networking by integrating AppliedMicro's mixed-signal PHY, photonic, and analog technologies, allowing comprehensive semiconductor support for enterprise and cloud data center optical systems.[3] Following the acquisition, MACOM divested AppliedMicro's compute business in October 2017 to an affiliate of The Carlyle Group; this business was reorganized as Ampere Computing, which in March 2025 agreed to be acquired by SoftBank Group for $6.5 billion (expected to close in late 2025, pending regulatory approvals).[5][6]
Corporate History
Founding and Early Development
Applied Micro Circuits Corporation was incorporated in California in 1979, where it commenced operations as a semiconductor company specializing in the design of custom integrated circuits. The company was reincorporated in Delaware in 1987 to facilitate its growth and public offering preparations.[1] From its inception, Applied Micro Circuits Corporation focused on developing application-specific integrated circuits (ASICs) for telecommunications and data communications markets, initially targeting high-speed analog and mixed-signal solutions for military and commercial applications before diversifying into broader networking sectors. This emphasis on custom ICs positioned the company as an early player in providing silicon solutions for emerging voice and data fiber-optic networks. By leveraging bipolar and BiCMOS process technologies, the firm addressed the need for high-performance, low-power components in these rapidly evolving fields.[7][8] The company's early revenue demonstrated robust growth, reaching $20.3 million in fiscal 1986, driven primarily by demand for its bipolar and BiCMOS-based products in telecommunications infrastructure. This expansion reflected the broader industry shift toward integrated solutions for data transmission, with sales diversifying from military contracts— which accounted for about 70% of revenue in the early 1980s—to commercial telecom applications by the late 1980s, significantly declining by the early 1990s.[8] Headquartered in Sunnyvale, California, Applied Micro Circuits Corporation expanded its operations throughout the 1990s, establishing additional facilities to support increased design and manufacturing needs, including a move to a larger complex to accommodate growing engineering teams. This infrastructural development enabled the company to scale its custom IC production and lay the groundwork for later innovations in embedded processors. In the early 2000s, the firm began transitioning toward MIPS-based processors to further enhance its connectivity offerings.[1][8]Key Milestones and Product Launches
In 1997, the company went public on the NASDAQ under the ticker symbol AMCC.[8] In 1995, Applied Micro Circuits Corporation transitioned to a fabless business model, outsourcing its manufacturing to third-party foundries such as TSMC to focus on design and development of high-performance integrated circuits.[9] This shift enabled the company to introduce its first application-specific standard products (ASSPs), including physical layer chips for ATM, SONET, and Fibre Channel networks, marking a pivotal move toward scalable production without owning fabrication facilities.[9] A major milestone occurred in 2004 when the company acquired IBM's PowerPC 400 core assets and related intellectual property for $227 million in cash, along with a license to the Power Architecture.[10] This acquisition provided Applied Micro with the foundation to develop embedded processors, expanding its portfolio beyond connectivity chips into high-performance computing applications.[11] In October 2011, Applied Micro announced the X-Gene platform, its first ARM-based server-on-a-chip processor utilizing the 64-bit ARMv8 architecture, aimed at delivering high-performance computing for data centers with integrated I/O and memory subsystems.[12] Building on this, the company launched the X-Gene 2 in 2015, featuring up to 16 ARMv8 cores operating at speeds around 2.5 GHz, enhanced microarchitecture for improved efficiency, and support for advanced interconnects to target cloud and hyperscale server markets.[13] In 2015, Applied Micro revealed plans for the X-Gene 3, a next-generation processor with 32 ARMv8 cores clocked up to 3 GHz, eight DDR4 memory channels, and non-blocking core-to-peripheral fabric, positioned for demanding data center workloads on TSMC's 16nm FinFET process.[14] The company's revenue experienced significant fluctuations during this period, peaking at $436 million in fiscal year 2001 amid strong demand for networking chips before declining sharply due to the dot-com bust and market saturation.[7] By fiscal year 2010, revenues had fallen to $206 million, accompanied by a net loss of $7.49 million, reflecting challenges in transitioning to new processor markets and competitive pressures in connectivity products.[15]Acquisition and Dissolution
On November 21, 2016, MACOM Technology Solutions Holdings, Inc. announced a definitive agreement to acquire Applied Micro Circuits Corporation (AMCC) in a transaction valued at approximately $770 million. The deal offered AMCC shareholders $3.25 in cash and 0.1089 shares of MACOM common stock per AMCC share, equating to $8.36 per share and representing a 15% premium over AMCC's closing price on the prior trading day. This acquisition aimed to bolster MACOM's position in high-speed connectivity solutions for data centers and telecommunications, particularly in optical and Ethernet technologies.[16][17] The acquisition was completed on January 26, 2017, making AMCC a wholly owned subsidiary of MACOM, after which AMCC's shares ceased trading on the NASDAQ Global Select Market. As part of the post-acquisition strategy, MACOM focused on integrating AMCC's connectivity products, which included high-speed physical layer (PHY) devices, OTN framers, and Ethernet solutions, into its existing portfolio of RF, microwave, and optical components. This integration enhanced MACOM's end-to-end offerings for optical networks, from analog and photonic elements to PHY layers, enabling comprehensive semiconductor support for data center and telecom applications. The connectivity assets aligned closely with MACOM's core expertise, allowing for seamless incorporation without the need for further divestitures in that segment.[18][16][19] In October 2017, MACOM divested AMCC's compute processor business—centered on ARM-based server processors—to Project Denver Holdings LLC, an affiliate of The Carlyle Group, in exchange for a minority equity stake in the newly formed venture. Announced on October 27, 2017, the transaction allowed the compute operations to operate independently under Carlyle's backing, with the goal of fostering long-term growth in that sector. This divestiture marked the effective dissolution of AMCC as an independent corporate entity, as its remaining assets were fully absorbed into MACOM's structure. Employees from the compute division transitioned to the new entity, which later became Ampere Computing, with key engineering talent retained to continue development of the X-Gene processor line. The move minimized operational disruptions for MACOM while providing a dedicated path for the non-core compute business.[20][5][21]Business Operations
Processor Products Division
The Processor Products Division of Applied Micro Circuits Corporation (AMCC) focused on developing high-performance embedded processors and server-on-a-chip solutions tailored for computing-intensive applications. Following the 2004 acquisition of IBM's PowerPC 400 series embedded processor line for $227 million, AMCC expanded its portfolio to include 32-bit RISC-based microcontrollers optimized for embedded systems.[22] These processors, such as the PPC440 and PPC460 families, delivered high performance with features like dual-issue superscalar execution, integrated peripherals including Ethernet controllers, and support for real-time operating systems, targeting sectors like networking, telecommunications, and data storage.[23] For instance, the PowerPC 460SX variant provided hardware acceleration for RAID 5 and RAID 6 operations, enabling throughput rates up to 1500 MB/s in storage applications while maintaining low power consumption suitable for embedded environments.[24] AMCC's processor innovations advanced significantly with the X-Gene family, a series of 64-bit ARMv8-A architecture-based system-on-chips designed for server and cloud computing. The X-Gene 1, launched in 2014 and fabricated on a 40 nm process, featured eight ARM Cortex-A57 cores operating at up to 2.4 GHz, with 32 KB L1 instruction and data caches per core, 256 KB L2 cache shared per pair of cores (1 MB total L2), an 8 MB shared L3 cache, and integrated support for DDR3 memory up to 128 GB.[25][26] It included a custom high-speed on-chip fabric for coherent interconnect between cores and I/O, along with dual 10 GbE controllers for networking, positioning it as an energy-efficient alternative for private cloud deployments.[27] The subsequent X-Gene 2, introduced in 2016 on a 28 nm process, featured eight ARMv8-A cores at speeds up to 2.4 GHz, incorporating enhanced integrated I/O such as PCIe Gen3 lanes and improved memory bandwidth for data center workloads.[28][29] Building on this foundation, AMCC planned the X-Gene 3 for high-performance computing, targeting a 16 nm FinFET process with 32 ARMv8-A cores clocked at up to 3.0 GHz, eight channels of DDR4-2667 memory supporting up to 1 TB capacity, and a non-blocking core fabric for scalable coherence across the die.[14] Key architectural features across the X-Gene lineup included a coherent mesh-like interconnect for low-latency data sharing, ECC-protected caches for reliability, and integration with high-speed Ethernet up to 10 GbE natively, with provisions for external 100 GbE connectivity in data center configurations.[30] These elements enabled efficient handling of virtualization, big data processing, and software-defined storage tasks. The X-Gene processors found applications in storage processors for RAID-optimized systems, cloud infrastructure platforms, and hyperscale server environments, supporting dense rack deployments.[31] For example, X-Gene-based servers were deployed in private clouds for web serving and database operations, leveraging open-source Linux support for rapid ecosystem integration.[28] In the market, AMCC positioned the X-Gene family as a direct competitor to Intel's Xeon processors and other ARM-based rivals, emphasizing superior performance-per-watt metrics for energy-constrained data centers, with projections for X-Gene 3 delivering up to six times the performance of its predecessor in hyperscale scenarios.[32] Following the 2017 acquisition by MACOM, the Processor Products Division was divested in October 2017 to an affiliate of The Carlyle Group, forming Ampere Computing, which continued development of ARM-based server processors.[20]Connectivity Products Division
The Connectivity Products Division of Applied Micro Circuits Corporation (AMCC) specialized in developing integrated circuits for high-speed data transmission and networking, focusing on physical layer (PHY) devices that supported Ethernet and Optical Transport Network (OTN) standards. These PHY devices facilitated reliable signal transmission in telecommunications and data center environments, incorporating serializer/deserializer (SerDes) technology optimized for low power consumption to meet the demands of dense, energy-efficient deployments. For instance, the QT2025 transceiver provided fully adaptive electronic dispersion compensation for 10Gbps links, enabling robust performance over fiber optic connections.[33] A core offering within the division included framers and mappers for SONET/SDH and OTN protocols, scaling up to 100G rates to support multi-service transport in metro and long-haul networks. Products such as the Yahara family, including the S10126 device, integrated framer, mapper, and PHY functions for 10GbE, 10G Fibre Channel, OC-192/STM-64, and OTU2 applications, allowing flexible mapping of Ethernet traffic into optical frames with forward error correction (FEC) for enhanced reliability. Higher-capacity solutions like the PQX series extended this capability to multi-10G, 40G, and 100G Carrier Ethernet and OTN, serving as highly integrated system-on-chips (SoCs) for transponders, muxponders, and cross-connects. Following the 2017 acquisition by MACOM Technology Solutions, these technologies were integrated into broader optical portfolios.[34][35] The division also produced switch fabric devices for high-speed packet processing in routers and switches, leveraging the Packet Routing Switch (PRS) family to enable scalable interconnects. Devices like the PRS 5G and PRS 20G provided granular, multi-purpose switching at rates up to 80G, supporting applications in storage area networks (SANs) and advanced telecommunications computing architecture (ATCA) systems with low-latency fabric connectivity. Key innovations included PAM-4 digital signal processors (DSPs) for 400G and beyond optical links, alongside retimers and gearboxes tailored for pluggable transceivers, which enhanced signal integrity and reduced power in high-density modules.[36][37][16] These products targeted cloud data centers, 5G infrastructure, and enterprise networking, where low-power SerDes enabled efficient scaling for bandwidth-intensive applications like video streaming and AI workloads. For example, the S20020 MACsec PHY supported dual 100G Ethernet links with integrated optics compatibility, securing data flows in hyperscale environments while minimizing thermal overhead. Overall, the division's emphasis on integrated, power-efficient solutions positioned AMCC as a key supplier for evolving optical and Ethernet ecosystems.[38][18]Strategic Growth
Major Acquisitions
Applied Micro Circuits Corporation (AMCC) pursued a series of acquisitions in the 2000s to bolster its capabilities in networking, processing, and storage technologies, with a total of five major deals that expanded its intellectual property portfolio and product offerings. These moves were strategically aimed at filling gaps in high-speed data processing, embedded cores, and optical transport solutions, particularly during the peak of the dot-com boom and subsequent recovery.[39] The company's most significant acquisition occurred in October 2000, when AMCC acquired MMC Networks Inc. for approximately $4.5 billion in stock, marking the second-largest semiconductor merger at the time. This deal integrated MMC's network processors into AMCC's lineup, enabling enhanced support for voice-over-IP (VoIP) applications and broadband networking equipment by combining AMCC's high-bandwidth analog and mixed-signal expertise with MMC's digital processing capabilities. The acquisition immediately strengthened AMCC's position in fiber-optic networking chips, allowing for rapid integration of MMC's nP7xxx series processors into AMCC's product roadmap for traffic management and packet processing.[40][41][42] In December 2003, AMCC expanded its storage networking portfolio by acquiring JNI Corp. for $196 million in cash, which included JNI's Fibre Channel host adapters and related intellectual property. This purchase addressed AMCC's need for specialized storage interconnect solutions, integrating JNI's technology to support high-performance data transfer in enterprise storage systems and complementing AMCC's existing WAN and embedded processing lines. The deal provided immediate access to JNI's established customer base in storage area networks, facilitating quicker market penetration for AMCC's storage-oriented chips.[43][44] AMCC further diversified in April 2004 by acquiring assets related to IBM's PowerPC 400 family for $227 million in cash, including embedded RISC core intellectual property, design teams, and licenses under the Power Architecture. This acquisition was highly synergistic with AMCC's WAN and storage IC portfolio, granting immediate revenue from the PowerPC cores and enabling the development of customizable embedded processors for networking and industrial applications. The integration allowed AMCC to leverage IBM's fabrication services while internalizing core design expertise to accelerate product innovation in reduced instruction set computing (RISC) technologies.[45][46][11] To enhance its connectivity offerings, AMCC acquired Quake Technologies Inc. in August 2006 for $69 million in cash, incorporating Quake's 10 Gb Ethernet transceivers and related physical layer (PHY) assets. This smaller deal targeted gaps in high-speed Ethernet interfaces for optical networks, with immediate integration of Quake's transceivers into AMCC's broadband and metro Ethernet products to support faster data rates in carrier infrastructure. The acquisition bolstered AMCC's analog front-end capabilities, enabling more competitive solutions in 10G networking without significant overlap in existing operations.[47] AMCC's final major acquisition in this period came in August 2010 with the purchase of TPACK A/S, a Danish firm specializing in optical transport network (OTN) technology, for $32 million in cash plus up to $5 million in performance-based earn-outs tied to revenues and milestones. This move enhanced AMCC's OTN mapping capabilities, particularly for 40G and 100G optical transport systems, by integrating TPACK's mapper intellectual property into AMCC's connectivity division for advanced metro and long-haul applications. The acquisition provided swift access to TPACK's expertise in OTN framing and multiplexing, supporting the growing demand for high-capacity optical data transport in telecommunications.[48][49][50] In June 2012, AMCC acquired Veloce Technologies for up to $178.5 million in cash and stock, including earn-outs based on product development milestones. This acquisition strengthened AMCC's portfolio in ARM-based server-on-a-chip solutions, integrating Veloce's 64-bit ARM processor technology to advance energy-efficient computing for data centers and cloud infrastructure.[1][51]Industry Memberships and Alliances

As a sponsor-level member of Power.org, AMCC supported the promotion and evolution of the Power Architecture platform, contributing to collaborative efforts among semiconductor firms to maintain its relevance in embedded and high-performance computing applications.[52] AMCC held membership in the Ethernet Alliance, where it played a role in developing specifications for high-speed Ethernet technologies, including contributions to the 10GBASE-T task force through representatives like Brad Booth. The company also engaged with the PCI Special Interest Group (PCI-SIG), ensuring compliance and innovation in I/O interface standards for its connectivity products, as evidenced by its development of PCI-compliant controllers. Additionally, AMCC participated in Multi-Source Agreements (MSAs) for optical modules, such as the QSFP MSA, which facilitated standardized transceiver designs for multi-gigabit optical networks and enabled interoperability among vendors.[53][54][55] A notable contribution came through the Open Compute Project (OCP), where AMCC donated the first ARM-based microserver specification in 2013, integrating its X-Gene processor to support open-source server designs optimized for data centers. This involvement provided AMCC with access to interoperability testing, influence over hardware roadmaps, and strategic partnerships with hyperscalers, including Facebook, the OCP's founder, fostering adoption of efficient, scalable compute solutions.[56][57]Legal and Financial Challenges
Class-Action Lawsuit
In 2001, shareholders of Applied Micro Circuits Corporation (AMCC) filed a securities class-action lawsuit in the U.S. District Court for the Southern District of California, alleging that the company and certain officers and directors violated federal securities laws through misleading statements about its operations and financial prospects.[58] The suit, consolidated under In re Applied Micro Circuits Corp. Securities Litigation (Case No. 01-CV-0649-K(AB)), claimed that defendants issued false projections of 16%-20% sequential revenue growth for the fourth quarter of fiscal 2001, overstated the solidity of a $133 million order backlog (representing 77% of the March quarter forecast), and misrepresented factors contributing to increased days sales outstanding in the third quarter, all amid the telecommunications industry downturn.[59] These actions purportedly created an artificial inflation of AMCC's stock price during the class period from November 30, 2000, to February 5, 2001, enabling insiders to sell nearly $100 million in shares at prices up to $87 per share before a February 5, 2001, disclosure of significant order cancellations for OC-12, OC-48, and OC-192 products caused the stock to plummet from $70 to $53 per share.[60][58] The allegations centered on a scheme to disseminate materially false and misleading information in violation of the Securities Exchange Act of 1934, particularly Sections 10(b) and 20(a), and Rule 10b-5, by failing to disclose material order push-outs and cancellations at subsidiary Monolithic Memory Circuits (MMC) while forecasting fourth-quarter earnings per share of $0.17 and full-year fiscal 2001 earnings per share of $0.57.[59] Filed initially on April 12, 2001, by the law firm Finkelstein & Krinsk on behalf of lead plaintiffs, the consolidated complaint sought damages for investors who purchased AMCC securities during the defined class period.[60][58] The litigation, spanning over four years, culminated in a $60 million cash settlement agreement announced on January 21, 2005, with approximately $31 million funded by the company's insurers and the remaining $29 million recorded as a charge against AMCC's earnings in the third quarter of fiscal 2005 (ended December 31, 2004).[61] Neither AMCC nor the individual defendants admitted any wrongdoing or liability as part of the resolution, which was designed to eliminate ongoing uncertainty and allow the company to focus on its business operations.[61] The settlement funds were placed into an interest-bearing escrow account pending court approval, with provisions for return if the agreement did not finalize.[62] The U.S. District Court granted final approval of the settlement on June 21, 2005, by Judge Judith N. Keep, dismissing the case with prejudice and concluding the federal proceedings.[58] The resolution prompted internal reviews and adjustments at AMCC, including leadership transitions such as the July 2001 resignation of CEO David M. Rickey from his additional role as president (while retaining his positions as chairman and CEO), amid broader scrutiny of executive practices during the period.[7] Post-settlement, the company enhanced its financial disclosure protocols to address investor concerns raised in the litigation.[61]Stock Options Backdating Scandal
In 2006, Applied Micro Circuits became embroiled in the broader stock options backdating scandal affecting numerous technology companies. An internal review revealed that certain stock option grants to executives and employees had been backdated to earlier periods when the company's stock price was lower, violating accounting standards and the company's stock option plans. This led to a restatement of financial results for fiscal years 1997 through 2005, with cumulative charges of approximately $51 million to prior periods' stock-based compensation expense, resulting in a $200 million non-cash charge announced in July 2006. The U.S. Securities and Exchange Commission (SEC) investigated the matter, and shareholder derivative lawsuits were filed alleging breaches of fiduciary duties by executives and the board. The company settled these derivative suits in 2008 for $14 million, without admission of liability, and implemented governance reforms including enhanced oversight of equity grants.[63][64]Merger-Related Class-Action Lawsuit
Following the November 2016 announcement of its acquisition by MACOM Technology Solutions, Applied Micro Circuits faced a class-action lawsuit filed in January 2017 in the U.S. District Court for the Northern District of California (Shah v. Applied Micro Circuits Corporation, Case No. 3:17-cv-00151). The suit, on behalf of shareholders who owned stock between November 21, 2016, and January 25, 2017, alleged that the company and its officers violated Sections 14(a) and 20(a) of the Securities Exchange Act of 1934 by issuing misleading proxy statements that undervalued the company and failed to disclose material information about the merger's terms and alternatives. The case was dismissed in 2018, with the court finding insufficient evidence of material misstatements.[65]Financial Performance Overview
Applied Micro Circuits Corporation (AMCC) experienced significant revenue growth during the late 1990s dot-com boom, reaching a peak of $435.5 million in fiscal year 2001 (ended March 31, 2001), driven by demand for its communications and networking semiconductors.[7] However, the subsequent bust led to a sharp decline, with revenues falling to $205.6 million in fiscal year 2010 (ended March 31, 2010), accompanied by a net loss of $7.5 million.[66] By fiscal year 2016 (ended March 31, 2016), revenues showed partial recovery to approximately $165 million on a trailing twelve-month basis, reflecting strength in connectivity products amid ongoing challenges in the processor segment.[16] Profitability was severely impacted by the dot-com downturn, resulting in cumulative losses including a $3.6 billion net loss in fiscal year 2002 alone, largely due to impairment charges on acquisitions and reduced demand for high-speed networking chips.[7] Aggressive expansion during the boom involved using approximately $1.2 billion in stock for acquisitions, which diluted shareholder equity and contributed to long-term financial strain as market conditions deteriorated.[67] AMCC went public in 1997, raising $44.4 million through its initial public offering, which funded early growth but proved insufficient to offset later losses.[68] Employee headcount peaked at around 920 in 2000 during the expansion phase but declined to approximately 600 by 2010 as the company restructured amid falling revenues.[9] Key financial ratios highlighted operational efficiencies and investment priorities in peak years, with gross margins typically ranging from 50% to 60% in the early 2000s, supported by high-margin custom ASICs.[69] Research and development spending averaged 20-25% of revenue during this period, underscoring AMCC's focus on innovation in PowerPC and networking technologies despite profitability pressures.[7] Leading into its 2017 acquisition by MACOM Technology Solutions, AMCC achieved an enterprise value of $770 million, primarily valuing its connectivity assets at a multiple reflecting market recovery in data center and cloud infrastructure.[16] The class-action lawsuit settlement in 2005 imposed additional costs of $29 million (the company's portion of the $60 million total) but did not fundamentally alter the overall revenue trajectory.[61]References
