factories. They focus exclusively on semiconductor design and outsource virtually every step of the manufacturing process, utilizing contract foundries to manufacture their semiconductors in wafer form and companies such as Amkor for their packaging and test needs. Some companies will engage a contract foundry to manage the complete semiconductor manufacturing process, and, in turn, the contract foundry will outsource some of its packaging and test needs.

**Industry background** 

Semiconductor devices are essential building blocks in most electronic products. As electronic and semiconductor devices have evolved, several important trends have emerged that have fueled the growth of the overall semiconductor industry, as well as the market for outsourced semiconductor packaging and test services. These trends include:

• Accelerating adoption of artificial intelligence applications by both enterprises and consumers, which has increased demand
of computing power at data centers and in edge computing devices such as smartphones, autonomous vehicles and consumer and industrial devices.

• Growing demand for smart mobile and connected devices, including the worldwide adoption of smartphones, tablets and other Internet-of-Things ("IoT") devices that can access the internet and provide multimedia capabilities.

• The proliferation of semiconductor devices into well-established end products such as automotive systems for advanced
driver assistance systems ("ADAS"), electrification and infotainment systems.

• The increased demand for new broadband wired and wireless networking equipment.

• The adoption of heterogeneous integration (diverse dies positioned close to each other within the same package) for
performance scaling beyond Moore's Law to achieve improved power efficiency, design flexibility and scalability in data center computing, artificial intelligence and similar end uses.

• The growth of advanced system-in-package ("SiP") modules (combining multiple semiconductor and other electronic components in a single package) to meet the demand for miniaturization and higher functionality at competitive cost.

• An increase in the semiconductor content within electronic products to provide greater functionality and higher levels of
performance.

• The continued build out of 5G infrastructure and 5G enabled devices.

• Digitalization, driving expansion of data generation and storage.

As a supplier in the semiconductor industry, our business is cyclical and impacted by broad economic factors, such as worldwide gross domestic product and consumer spending. With the exception of 2020, when the Covid-19 pandemic caused worldwide gross domestic product levels to decline during a period of strong growth in the semiconductor industry, there has generally been a strong correlation between worldwide gross domestic product levels, consumer spending and semiconductor industry cycles. The semiconductor industry has experienced significant and sometimes prolonged cyclical upturns and downturns in the past. We cannot predict the timing, strength or duration of any correction, economic slowdown, recession or subsequent economic recovery.

***Outsourcing Trends in Semiconductor Manufacturing***

Semiconductor companies outsource their packaging and test needs to service providers such as Amkor for the following reasons:

*Packaging and test service providers have developed expertise in advanced technologies.* 

The increasing demands for miniaturization, greater functionality, lower power consumption and improved thermal and electrical performance are driving the continuous development of semiconductor packaging and test technologies that are more sophisticated, complex, capital intensive and customized. This trend has led many semiconductor companies and OEMs to view packaging and test as enabling technologies that can benefit from the technological innovation expertise found in the leading outsourced assembly and test companies. At the same time, these companies are often looking to reduce their internal manufacturing and research and development costs for packaging and test solutions. As a result, many of these companies are increasingly relying on packaging and test service providers as key sources for new package designs and advanced interconnect technologies.

*Packaging and test service providers can facilitate a more efficient supply chain and help shorten time-to-market for new products.* 

We believe that semiconductor companies, together with their customers, are seeking to shorten the time-to-market for new products and that an efficient supply chain is a critical factor in facilitating timely and successful product introductions. Packaging and test service providers have the resources and expertise to timely develop and implement new packaging technology in high volume. For this reason, semiconductor companies and OEMs are leveraging the capabilities of outsourced packaging and test service providers to bring new high quality products to market more quickly.

*High quality packaging and test service providers enable semiconductor manufacturers to focus their resources on semiconductor design and wafer fabrication.* 

As semiconductor process technology migrates to larger wafers and smaller feature sizes, the cost of building a state-of-the-art wafer fabrication factory has risen significantly. The high cost of investing in next generation silicon technology and equipment is causing many semiconductor companies to adopt or maintain a "fabless" or "fab-lite" strategy to reduce or eliminate their investment in wafer fabrication and associated packaging and test operations. As a result, these companies are increasing their reliance on outsourced providers of semiconductor manufacturing services, including high quality packaging and test solutions.

*Packaging and test service providers offer a cost-effective solution in a cyclical, capital intensive industry.* 

The semiconductor industry is cyclical by nature and impacted by broad economic factors, such as changes in worldwide gross domestic product and consumer spending. Semiconductor packaging and test are complex processes requiring substantial investment in specialized equipment, factories and human capital. As a result of this cyclicality and the large investments required, manufacturing facilities must operate at consistently high levels of utilization to be cost-effective. Shorter product life cycles, coupled with the need to update or replace packaging and test equipment to accommodate new package types, make it more difficult for IDMs to maintain cost-effective utilization of their packaging and test assets throughout semiconductor industry cycles. Packaging and test service providers, on the other hand, can typically use their assets to support a broad range of customers and multiple end markets, potentially generating more efficient use of their production assets and a more cost-effective solution.

Our Advanced Products include the following packaging types: flip-chip chip-scale packages ("FC CSP"), flip chip ball grid array ("FCBGA"), memory, and wafer-level packages. These package families use flip chip interconnect technology so that the die can be connected to a substrate package carrier or, in the case of wafer-level chip scale packages, directly to a printed circuit board.

*FC CSP Package Products:* FC CSP packages are small form factor packages where the substrate size is not much larger than the die itself.

• FC CSP can be a single die or multi die format. The size advantage provided by CSP technologies has made FC CSP an
attractive choice for a wide variety of applications that require very small form factors, such as smartphones, tablets and other mobile consumer electronic devices.

• Flip chip stacked chip scale packages ("FC SCSP") stack a second die on top of the original flip-chip die. The
top die is typically a memory device, and wirebond interconnects are used to attach the top die to the substrate. FC SCSP is frequently used to stack memory on top of digital baseband and applications processors for use in mobile devices.

• Package on Package ("PoP") technology innovations drive thinner package solutions through the development of
ultra-thin substrates and enhancing our pre-stacking and thin die handling capabilities.

• Fine pitch copper pillar flip chip interconnect technology creates interconnects at finer pitches using a plating process
to reduce the number of substrate layers to facilitate very thin packages. This innovative solution is also an enabling technology for package stacking with TSVs.

*FCBGA Products:* FCBGA packages are large form factor substrate-based packages which are used where processing power and speed are a higher priority than a small form factor. Our FCBGA packages are assembled using state-of-the-art substrates. Utilizing multiple high density routing layers, laser drilled vias, and ultra-fine line and space metallization, FCBGA substrates have the highest routing density available. The variety of FCBGA package options, from large single die to multi-chip packages with memory, allows package selection to be tailored to the specific thermal needs of the end product. We offer FCBGA packaging in a variety of product formats to fit a wide range of end application requirements, including networking, storage, computing, automotive and consumer applications. Some FCBGA products incorporate 2.5D technology, which utilizes high density silicon interposers to enable the integration of high-performance chips, such as high bandwidth memory and graphics processors, into a single package.

*Memory Products:* Memory packages consist of either standalone packaging and testing or a combination of NAND Flash, DRAM, or a memory controller IC using a variety of packaging technologies, including FC, SCSP, SiP

and other state-of-the-art packaging technologies. These products are used as system memory or platform data storage in all of our end markets.

*Wafer-level Package Products:* We offer various types of wafer-level packages: wafer-level CSP; WLFO; SiPh and CPO; and HDFO. Wafer-level CSP and WLFO are complementary technologies and customers can choose between these package types as their die sizes shrink or grow.

• Wafer-level CSP packages (also known as fan-in wafer-level packages) do not utilize
a package carrier. The bumped wafer is singulated into individual die, and the wafer-level package is then attached directly to the system board. Wafer-level CSP offers one of the lowest total system costs, enabling higher semiconductor content
while leveraging the smallest form factor and one of the highest performing, most reliable semiconductor package platforms on the market today. Applications for wafer-level CSP include power management, transceivers, sensors, wireless charging,
codecs, and specialty silicon for new or unique functionality.

• WLFO packages (also known as low-density fan-out packages) are utilized for ICs where the die surface area is too small to accommodate all of the required bond pads. The fan-out package enlarges the bondable
surface area by building a border around the die using low-cost molding compound. These packages can include multiple die. Applications for WLFO packages include power management, transceivers, radar and
specialty silicon.

• SiPh and CPO allow for the integration of fiberoptic interconnects both within a package and within the server architecture
to reduce power consumption, heat generation and improve performance. Amkor has supported previous generations of SiPh packaging needs and is aligned with the market to support its future needs, through chip on wafer, chip on chip and other advanced
packaging solutions.

• HDFO can either replace the laminate substrate with a thinner structure or reduce the complexity of the substrate by
housing the dense interconnects and bridges in the RDL structure, allowing for a less expensive substrate that provides a high level of performance with a balanced cost structure. HDFO solutions enable high performance in a compact form factor that
combines tiled processors, memory, I/O (input/output) die and other peripheral ICs.

*Mainstream products* 

Our Mainstream Products use wirebond interconnect technology to connect a die to a leadframe or substrate package carrier and include leadframe packages, substrate-based wirebond packages and micro-electro-mechanical systems ("MEMS") packages.

*Leadframe Packages:* Leadframe packages use wirebond or flip chip technology to connect a die to a leadframe package carrier. Leadframe packages are used in many electronic devices and remain the most practical and cost-effective solution for many low to medium pin count analog and mixed signal applications.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Traditional leadframe packages support a wide variety of device types and applications. Two of our most popular traditional
leadframe package types are small outline IC and quad flat package, commonly known as "dual" and "quad" products, respectively, based upon the number of sides from which the leads extend. The traditional leadframe package
family has evolved from "through hole design," where the leads are plugged into holes on the circuit board to "surface mount design," where the leads are soldered to the surface of the circuit board. We offer a wide range of
lead counts and body sizes to satisfy variations in the size of customers' semiconductor devices.

------

##### [**Table of Contents**](#toc)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Through a process of continuous engineering and customization, we have designed several leadframe package types that are
thinner and smaller than traditional leadframe packages and can accommodate more leads on the perimeter of the package. These leadframe packages typically have superior thermal and electrical characteristics, which allow them to dissipate heat
generated by high-powered semiconductor devices while providing enhanced electrical connectivity. We are developing increasingly smaller versions of these packages to keep pace with continually shrinking semiconductor device sizes and demand for
miniaturization of portable electronic products. One of our more successful leadframe package offerings is the *Micro* LeadFrame family of quad flat no lead packages. These packages offer cost effective, miniaturized solutions for multiple
analog power and signal chain applications.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Power discrete devices use a leadframe as the package carrier and primarily use wirebond interconnect technology. However,
power applications that require improved thermal and electrical performance will use packaging with copper clip interconnect technology that creates multi die power modules with wafers from silicon carbide and other wide band gap materials.

*Substrate-based Wirebond Packages:* Substrate-based wirebond packages use wirebond technology to connect a die to a substrate. Some of our packages in this category include stacked CSP, wirebond ball grid array packages and plastic ball grid array ("PBGA") packages.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Stacked CSP technology enables the stacking of a wide range of different semiconductor devices to deliver high levels of
silicon integration and area efficiency. Stacked CSP utilizes high density thin core substrates and advanced materials, along with leading-edge wafer thinning, die attach and molding capabilities, to stack multiple die on a substrate. Stacked CSP is
ideal for memory and mixed signal applications.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Wirebond ball grid array packages offer a broad selection of ball array pitches, ball counts and body sizes, single and multi-die layouts, stacked die and passive component integration together with thermal management solutions. They are applicable for a wide range of semiconductors requiring a smaller package size than conventional
PBGAs or leadframe packages.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• PBGA packages are used in applications requiring higher pin count than leadframe packages, but typically have lower pin
counts than flip chip. PBGA packages are designed for low inductance, improved thermal operation and enhanced surface-mount technology ability. Custom performance enhancements, like ground and power planes, are also available.

*Micro-Electro-Mechanical Systems Packages:* MEMS are miniaturized mechanical and electro-mechanical devices that can sense and provide information about the physical world and sometimes trigger a response. Examples of MEMS devices include microphones, accelerometers, airbag deployment sensors, gyrometers, magnetometers and humidity, temperature and pressure sensors. We also specialize in sensor fusion products which utilize our cavity MEMS platform and combine multiple sensors into a single package. MEMS packages leverage our expertise in wafer thinning, die stacking, wirebonding and flip chip interconnect to deliver sophisticated products with a very small form factor.

*Advanced system-in-package modules* 

Advanced SiP modules combine multiple semiconductor and other electronic components with different functionalities into a single package. These modules use wirebond, flip chip or wafer-level interconnect technologies. Components can include ICs, passive devices (inductors, capacitors, resistors, filters and diplexers), antennas and mechanical parts.

------

##### [**Table of Contents**](#toc)
The increasing demand for miniaturization and higher functionality at competitive cost is driving the adoption of advanced SiP in new products. Advanced SiP modules are used for many applications such as radio frequency ("RF") and front-end modules, basebands, connectivity, fingerprint sensors, display and touch screen drivers, sensors and MEMS, NAND memory and solid state drives. Advanced SiP modules are found in many products including smartphones and tablets, automobiles, IoT wearables, high-performance gaming systems, computers and network systems.

In 2024, 2023 and 2022, we had net sales of approximately $3,085 million, $2,955 million and $2,930 million, respectively, from our advanced SiP modules, which are mostly included in Advanced Products, depending upon the interconnect technology used in the module.

*Test services* 

Our Test Services complement our wafer and packaging services across our Advanced and Mainstream Products. Our test services offer customers the cycle time and cost advantages of co-located turn-key services and are differentiated by our geographically diverse locations, high quality execution and delivery, and expertise, particularly for wafer level test. Our test services are used as both an interim step or as the final testing step to ensure screening and rejection of defects, performance grading and overall outgoing quality and reliability. Interim testing eliminates the manufacturing costs of assembling the defective chips. Below is a description of our test services:

• *Wafer Level Test:* Wafer level test is a manufacturing step performed while a wafer is still in its full form and
before being singulated for further package processing.

• *Package Level Test:* Package level test is performed on a product or products that have been assembled in a package.

• *Burn-In Test:* Burn-in test is a
process in which components of a system are exercised, monitored and measured in extreme operational conditions such as high temperature, voltage and frequency over time. The purpose of the environmental and operational stress conditions of burn-in testing is to accelerate and screen early life failures and estimate and monitor long-term degradation and ultimate lifetime.

• *System Level Test:* System level test identifies defective products that may not otherwise be screened by traditional
wafer level, package level or burn-in testing. As advanced packaging proliferates and the integration of more individual components into a package grows, system level testing becomes more important.

• *Test Development Services:* Prior to mass production, an integrated manufacturing ready test solution must be
developed and deployed. Amkor's test development services offer both co-development and full development of complete test software and hardware solutions to our customers. These services also enable
early engagement with our customers in the product design phases for maximum compatibility with manufacturing. Our test development teams are experienced in a full suite of test engineering disciplines for Memory, Power, RF, Mixed Signal, Analog and
digital test solution development.

**Research and development** 

We believe that technology development is one of the keys to success in the semiconductor packaging and test industry. Our research and development efforts focus on progressing packaging technologies and test solutions to meet evolving customer needs for higher performance, greater integration, smaller form factors, and lower costs. Key areas of focus include:

• Heterogeneous integration: Developing multi-chip module solutions, including 2.5D and HDFO with and without bridges,
that enable package level integration of different types and levels of silicon technologies for high performance computing, networking and data center applications. This is accomplished by combining processors, chiplets, or integrated passive
devices into one packaged module. Through die partitioning and heterogeneous integration, these modules provide higher functionality at lower total product cost.

• Wafer-level and panel-level packaging: Innovating 2D and 3D wafer-level chip-scale packages and WLFO packages are
increasingly the preferred package type for many applications in IoT and mobile devices, including processors, power management integrated circuits ("PMICs"), display drivers and antenna package products. We believe that our development
of Panel Level Fan Out ("PLFO") technology will permit higher economies of scale for fan-out package devices manufactured on a panel versus wafer basis.

• Copper hybrid bonding: Developing an emerging 3D integration technique that directly joins copper interconnects between
stacked chips or wafers, enabling extremely dense, ultra fine pitch interconnects to provide performance and power advantages over traditional microbump interconnects.

• Highly integrated SiP modules: Creating compact, cost efficient modules such as DSMBGA and DSMLGA packages to minimize form
factor and reduce material and processing costs for wearables and mobile devices.

• Advanced Automotive packaging: Developing new package technologies as higher performance computing, energy efficiency,
power distribution and sensor content are used to support new automotive features

------

##### [**Table of Contents**](#toc)
including ADAS, infotainment, optical sensors and electric vehicles. In addition, we are developing high power modules involving SiC-based devices.

• Co-Packaged Optics: Advancing CPO technologies to participate in the scaling of the
datacenter and artificial intelligence industries. We believe that our CPO packaging technology developments will permit ever increasing interface bandwidth improvements between processors, artificial intelligence accelerators, memory and other
support components, all coupled together through our CPO solutions.

Our research and development teams are located across our facilities with the primary Center of Excellence based in Korea. In 2024, 2023 and 2022, we incurred $163.0 million, $177.5 million and $149.4 million, respectively, of research and development expense.

**Sales and marketing** 

Our sales offices are located throughout Asia, Europe and the United States. Our support personnel manage and promote our packaging and test services and provide key customer and technical support. To provide comprehensive sales and customer service, we typically assign our customers a direct support team consisting of a sales manager, assembly and test technical program managers and both field and factory customer support representatives. We also support our largest multinational customers from multiple geographic office locations to ensure that we are aligned with their global operational and business requirements.

Our direct support teams are further supported by an extended staff of product, process, quality and reliability engineers, as well as marketing and advertising specialists, information systems technicians and factory personnel. Together, these direct and extended support teams deliver an array of services to our customers.

**Seasonality** 

Our sales have generally been higher in the second half of the year than in the first half due to consumer buying patterns in the United States, Europe and Asia and the timing of flagship mobile device launches. In addition, semiconductor companies generally reduce their production during the holidays at the end of December, which generally results in a decrease in packaging and test services during the first quarter. General economic conditions, changes in our product mix or overall demand in any of our end markets can impact our seasonality.

**Customers** 

Our customers include most of the world's largest semiconductor companies. Our ten largest customers accounted for 72% of our net sales in 2024. Direct sales to Apple and Qualcomm accounted for 30.8% and 10.2% of our net sales, respectively, for the year ended December 31, 2024.

**Materials and equipment** 

***Materials***

Our materials are used primarily for packaging activities. Our packaging operations depend upon obtaining adequate supplies of materials on a timely basis. The principal materials used in our packaging process are laminate substrates, ICs, capacitors, leadframes and bonding wires. The silicon wafer is generally consigned from our customer. We generally do not take ownership of the customer consigned wafer, and title and risk of loss remains with the customer for these materials. Test materials constitute a very small portion of our total test cost. Generally, we purchase materials based on Amkor's commitments to customer forecasts, and our customers are generally responsible for any unused materials we purchase based on such commitments.

------

##### [**Table of Contents**](#toc)
We obtain the materials required for packaging services from various suppliers and source most of our materials, including critical materials such as leadframes, laminate substrates and bonding wires, from a limited group of suppliers. We work closely with our primary material suppliers to ensure consistent quality, availability and timely delivery. We also negotiate worldwide pricing agreements with our major suppliers to take advantage of the scale of our operations.

***Equipment***

Our ability to meet the changing demand from our customers for manufacturing capacity depends upon obtaining packaging and test equipment in a timely manner. We work closely with our main equipment suppliers to coordinate the ordering and delivery of equipment to meet our expected capacity needs.

The primary types of equipment used in providing our packaging services are wire bonders, die bonders, chip shooters and die attach. In addition, we maintain a variety of other packaging equipment, including mold, singulation, ball attach and wafer backgrind, along with numerous other types of manufacturing equipment. A substantial portion of our packaging equipment base can generally be used and adapted to support the manufacture of many of our packages.

We also purchase wafer bumping equipment to facilitate our flip chip and wafer level packaging services such as 2.5D and HDFO, which is used for HPC and artificial intelligence systems. Wafer bumping equipment includes sputter and spin coaters, electroplating equipment, reflow ovens and other types of equipment. This equipment tends to have longer lead times for delivery and installation than other packaging equipment and is sold in relatively larger increments of capacity.

The primary equipment used in the testing process includes testers, handlers and probers. Handlers are used to transfer individual or small groups of packaged ICs to a tester. Test equipment is generally a more capital-intensive activity than packaging, and test equipment tends to have longer delivery lead times than most types of packaging equipment. We focus our capital expenditures on standardized tester platforms to maximize test equipment utilization where possible. In some cases, our customers will consign test equipment to us.

**Governmental regulations** 

As a public company with global operations, we are subject to various federal, state, local and foreign laws, and our products and services are governed by a number of rules and regulations. These regulations, which differ among jurisdictions, include financial and other external reporting disclosure rules, accounting standards and environmental, corporate governance, intellectual property, tax, trade, antitrust, employment, immigration and travel, privacy and anti-corruption laws. Costs and accruals incurred to comply with these governmental regulations are presently not material to our capital expenditures, results of operations and competitive position. Although there is no assurance that existing or future government laws applicable to our operations, services or products will not have a material adverse effect on our capital expenditures, results of operations and competitive position, we do not currently anticipate material expenditures for compliance with government regulations.

***Environmental matters***

We use chemicals and materials in the semiconductor packaging process that generate byproducts such as wastewater, solid waste and flue gas. For example, water used for rinsing or cooling wafers being sawed or used in the etching or solder deposition process produces wastewater. Scrap from metal lead-frame or substrate processing or excessive molding resin produces solid waste. Emissions from solvents used for coating produce flue gases. In addition to byproducts, semiconductor packages have historically contained lead, a

------

##### [**Table of Contents**](#toc)
naturally occurring element that can be toxic. The use of lead in our packages has decreased over time due to the use of lead-free alternatives. The use and storage of chemicals and materials are subject to various laws and regulations governing waste disposal, water discharge, emissions into the atmosphere and employee health and safety. We make continuous efforts to comply with these environmental laws and regulations, including environmental management systems, safety training for employees and pollution control at our factories.

In the future, we may be subject to changes to existing environmental regulations or new green initiatives required by our customers, investors, governments or other stakeholders. We do not believe that capital expenditures or other costs attributable to compliance with environmental laws and regulations or green initiatives will have a material adverse effect on our business, liquidity, results of operations, financial condition or cash flows.

**Competition** 

The outsourced semiconductor packaging and test market is highly competitive, and geopolitical trade tensions have increased competition from Chinese firms supporting a China-for-China supply chain. We face competition from established packaging and test service providers primarily located in Asia, including ASE Technology, JCET Group and Powertech Technology.

Additionally, we compete with contract foundries, and electronic manufacturing service providers or contract electronics manufacturers, which offer certain types of advanced packaging. Our IDM customers also evaluate our services and scale against their own in-house capabilities.

The key competitive factors in the outsourced semiconductor packaging and test services market are:

• Advanced packaging technology

• Geographic location of services

• Manufacturing scale and expertise

• Customer co-development and innovation

• Investment in new technology and capacity

• Quality and reliability

• Price

• Cycle time

We believe we are competitive in these areas.

**Intellectual property** 

We maintain an active program to protect and derive value from our investment in technology and the associated intellectual property rights. Intellectual property rights that apply to our various products and services include patents, copyrights, trade secrets and trademarks. We have filed and obtained a number of patents in the United States and other countries, and their durations vary depending on the jurisdiction in which each patent is filed. Although our patents are an important element of our intellectual property strategy, we are not materially dependent on any one patent or any one technology. We expect to continue to file patent applications when appropriate to protect our proprietary technologies, but we cannot provide assurances that

------

##### [**Table of Contents**](#toc)
we will receive patents from pending or future applications. In addition, any patents we obtain could be challenged, invalidated or circumvented and may not provide meaningful protection or other commercial advantage to us. Nonetheless, we believe that our patents afford an important means of protection for our technologies. Further, to distinguish our products from our competitors' products, we have obtained certain trademarks and service marks and may promote our particular brands through advertising and other marketing techniques.

We also protect and maintain the confidentiality of certain information about our processes, products and strategies which we believe provides us with a competitive advantage. We have ongoing programs designed to maintain the confidentiality of such information. As part of these efforts, all employees who have access to Amkor's information systems are required to participate in cybersecurity training within the first 15 days of employment, after which recurring mandatory training is required on an annual basis.

**Human capital resources** 

Amkor believes that its future success is highly dependent upon our continued ability to attract, retain and motivate qualified employees. As part of our effort to attract and motivate employees, Amkor is committed to providing competitive and comprehensive benefits that are designed to enable our employees and their families to live healthier and more secure lives. Additionally, Amkor has implemented various retention programs to incentivize and retain high-performing employees. We regularly evaluate such retention programs and our compensation practices generally to ensure they remain competitive and are aligned with local market practices. We look to promote our management-level employees from within Amkor, and we believe that we have been successful in this effort. Factory locations also maintain training and development programs that enable the continued learning and growth of our employees, and senior management regularly meets to share and implement best practices among our various facilities.

Amkor also uses human capital initiatives to support our broad geographic footprint. For career development and advancement, we may provide employees with the opportunity to move between factories, often in support of new factories or the introduction of new packaging offerings. We believe that these initiatives are efficient for training new local employees and allow existing employees to continue to develop in their careers.

We believe that our efforts to motivate, retain and support the growth of qualified employees is reflected in the long average tenure of many of our key employees.

As of December 31, 2025, Amkor employed 30,800 employees, of whom approximately 95%, 4% and 1% resided in the Asia-Pacific region, Europe and the United States, respectively. Our global workforce spans 12 countries, reflecting various cultures, backgrounds, ages, genders and ethnicities. Our employees in France, Germany, the Philippines, Singapore and the United States are not represented by any union. Certain employees at our factories in China, Japan, Korea, Malaysia, Portugal, Taiwan and Vietnam are members of a union, and we operate subject to collective bargaining agreements that we have entered into with these unions. We believe that our relations with our employees are good, and we have not experienced a work stoppage in any of our factories.

**Risk factors** 

*An investment in our Common Stock involves risks. You should carefully consider the risks described below, as well as the other information included or incorporated by reference in this prospectus supplement and accompanying prospectus, before making an investment decision. Our business, liquidity, results of operations, financial condition or cash flows could be materially adversely affected by any of these risks.

In addition, the risks discussed below also include forward-looking statements and our actual results may differ materially from those discussed in such forward-looking statements. You should also review the section of this prospectus supplement and accompanying prospectus entitled "Special Note Regarding Forward-Looking Statements." Please note that additional risks not presently known to us or that we currently deem immaterial may also impair our business, liquidity and operations.* 

**Risks related to our common stock and this offering** 

***Susan Y. Kim and members of her family can effectively determine or substantially influence the outcome of all matters requiring stockholder approval.***

As of December 31, 2025, Susan Y. Kim, the Chairman of our Board of Directors, and members of the Kim family and affiliates owned approximately 132.1 million shares, or approximately 53% of our outstanding Common Stock. The Kim family also has options to acquire approximately 0.6 million shares. If the options are exercised, the Kim family's total ownership would be an aggregate of approximately 132.7 million shares, or approximately 54% of our outstanding Common Stock.

In June 2013, the Kim family exchanged convertible notes issued by Amkor in 2009 for approximately 49.6 million shares of our Common Stock (the "Convert Shares"). As of December 31, 2025, the Kim family owns 39.6 million Convert Shares. The Convert Shares owned by the Kim family are subject to a voting agreement. The voting agreement requires the Kim family to vote these shares in a "neutral manner" on all matters submitted to our stockholders for a vote, so that such Convert Shares are voted in the same proportion as all of the other outstanding securities (excluding the other shares owned by the Kim family) that are actually voted on a proposal submitted to Amkor's stockholders for approval. The Kim family is not required to vote in a "neutral manner" any Convert Shares that, when aggregated with all other voting shares held by the Kim family, represent 41.6% or less of the total then-outstanding voting shares of our Common Stock. The voting agreement for the Convert Shares terminates upon the earliest of (i) such time as the Kim family no longer beneficially owns any of the Convert Shares, (ii) consummation of a change of control (as defined in the voting agreement) or (iii) the mutual agreement of the Kim family and Amkor. Certain of the Convert Shares are being offered in this offering and will no longer be subject to the Voting Agreement when sold.

Immediately following this offering, the Kim family will continue to own approximately 49.5% of the outstanding voting shares of our Common Stock, or 48.9% if the underwriter exercises in full its option to purchase additional shares, which means that, based on their percentage voting power owned after the offering, Ms. Kim and her family and affiliates, acting together, will continue to have the ability to effectively determine or substantially influence matters submitted for approval by our stockholders including the election of our Board of Directors, by voting their shares or otherwise acting by written consent. There is also the potential, through the election of members of our Board of Directors, that the Kim family could substantially influence matters decided upon by our Board of Directors. This concentration of ownership may also have the effect of impeding a merger, consolidation, takeover or other business consolidation involving us, or discouraging a potential acquirer from making a tender offer for our shares, and could also negatively affect our stock's market price or decrease any premium over market price that an acquirer might otherwise pay.

------

##### [**Table of Contents**](#toc)
Concentration of ownership also reduces the public float of our Common Stock. There may be less liquidity and higher price volatility for the stock of companies with a smaller public float compared to companies with broader public ownership. Also, the sale or the prospect of the sale of a substantial portion of the Kim family shares may cause the market price of our Common Stock to decline significantly.

***The market price of our Common Stock may be volatile and could decline after this offering.***

Volatility in the market price of our Common Stock may prevent you from being able to sell your shares at or above the price you paid for your shares. The market price of our Common Stock may fluctuate significantly. Among the factors that could affect our stock price are:

• market conditions in our industry or the broader stock market;

• actual or anticipated fluctuations in our quarterly financial and operating results;

• changing economic conditions;

• introduction of new solutions or services by us or our competitors;

• issuance of new or changed securities analysts' reports or recommendations;

• sales, or anticipated sales, of large blocks of our Common Stock, including by the Kim family;

• additions or departures of key personnel;

• regulatory or political developments;

• litigation and governmental investigations;

• investors' perception of us;

• events beyond our control such as weather, war, and health crises; and

• any default on our indebtedness.

In particular, we cannot assure you that you will be able to resell your shares at or above the public offering price. Stock markets have experienced extreme volatility in recent years that has been unrelated to the operating performance of particular companies. These broad market fluctuations may adversely affect the trading price of our Common Stock. In the past, following periods of volatility in the market price of a company's securities, class action litigation has often been instituted against the affected company. Any litigation of this type brought against us could result in substantial costs and a diversion of our management's attention and resources, which could materially and adversely affect our business, financial position, results of operations, and cash flows.

***An active, liquid trading market for our Common Stock may not be sustained.***

Although our Common Stock is currently quoted on Nasdaq under the symbol "AMKR", an active trading market for our shares may not be sustained. Accordingly, if an active trading market for our Common Stock is not maintained, the liquidity of our Common Stock, your ability to sell your shares of our Common Stock when desired and the prices that you may obtain for your shares of Common Stock will be adversely affected.

(1) The number and percentage of shares beneficially owned is determined in accordance with Rule 13d-3 under the Exchange Act. The information is not necessarily indicative of
beneficial ownership for any other purpose. Under this rule, beneficial ownership includes any share over which the individual or entity has voting power or investment power, which includes the power to dispose of or to direct the disposition of

ownership percentage, but not for purposes of computing any other person's percentage. Under these rules, more than one person may be deemed to be a beneficial owner of the same securities, and a person may be deemed to be a beneficial owner
of securities as to which such person has no economic interest. The information contained in the table is not necessarily indicative of beneficial ownership for any other purpose, and the inclusion of any shares in the table does not constitute an

**Underwriting** 

The Selling Stockholder is offering the shares of Common Stock described in this prospectus supplement through Goldman Sachs & Co. LLC, as the underwriter. We and the Selling Stockholder have entered into an underwriting agreement with the underwriter. Subject to the terms and conditions of the underwriting agreement, the Selling Stockholder has agreed to sell to the underwriter, and the underwriter has agreed to purchase, at the public offering price less the underwriting discounts and commissions set forth on the cover page of this prospectus supplement, the number of shares of Common Stock listed next to its name in the following table:

---

| | | |
|:---|:---|:---|
| **Underwriter** | **Number of<br>Shares** | **Number of<br>Shares** |
|  Goldman Sachs & Co. LLC |  | 10000000 |

---

The underwriter is committed to purchase all the shares of Common Stock offered by the Selling Stockholder if they purchase any shares, other than those shares covered by the underwriter's option to purchase additional shares described below.

The underwriter is offering the shares, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the shares, and other conditions contained in the underwriting agreement, such as the receipt by the underwriter of officer's certificates and legal opinions. The underwriter reserves the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

The underwriter proposes to offer the shares of Common Stock directly to the public at the initial public offering price set forth on the cover page of this prospectus and to certain dealers at that price less a concession not in excess of $0.130 per share. Any such dealers may resell shares to certain other brokers or dealers at a discount of up to $0.065 per share from the initial public offering price. After the initial offering of the shares to the public, if all of the common shares are not sold at the initial public offering price, the underwriter may change the offering price and the other selling terms. Sales of any shares made outside of the United States may be made by affiliates of the underwriter.

The underwriter has an option to buy up to 1,500,000 additional shares of Common Stock from the Selling Stockholder to cover sales of shares by the underwriter in the initial offering of the shares or in the open market which exceed the number of shares specified in the table above. The underwriter has 30 days from the date of this prospectus supplement to exercise this option to purchase additional shares. If any shares are purchased with this option to purchase additional shares, the underwriter will purchase shares in approximately the same amount as shown in the table above. If any additional shares of Common Stock are purchased, the underwriter will offer the additional shares on the same terms as those on which the shares that are being offered.

on the price of the Common Stock in the open market that could adversely affect investors who purchase in this offering. To the extent that the underwriter creates a naked short position, they will purchase shares in the open market to cover the position.

The underwriter has advised us that, pursuant to Regulation M of the Securities Act, they may also engage in other activities that stabilize, maintain or otherwise affect the price of the Common Stock, including the imposition of penalty bids. This means that if the underwriter purchases Common Stock in the open market in stabilizing transactions or to cover short sales, the underwriter may be required to repay the underwriting discount received by it.

These activities may have the effect of raising or maintaining the market price of the Common Stock or preventing or retarding a decline in the market price of the Common Stock, and, as a result, the price of the Common Stock may be higher than the price that otherwise might exist in the open market. If the underwriter commences these activities, they may discontinue them at any time. The underwriter may carry out these transactions on The Nasdaq Global Select Market, in the over-the-counter market or otherwise.

In connection with this offering, the underwriter and selling group members may engage in passive market making transactions in the common stock on the Nasdaq Global Market in accordance with Rule 103 of Regulation M under the Exchange Act during a period before the commencement of offers or sales of common stock and extending through the completion of distribution. A passive market maker must display its bid at a price not in excess of the highest independent bid of that security. However, if all independent bids are lowered below the passive market maker's bid, that bid must then be lowered when specified purchase limits are exceeded. Passive market making may cause the price of our common stock to be higher than the price that otherwise would exist in the open market in the absence of those transactions. The underwriter and dealers are not required to engage in passive market making and may end passive market making activities at any time.

**Material U.S. federal income tax consequences to NON-U.S. Holders** 

The following discussion is a summary of the material U.S. federal income tax consequences to Non-U.S. Holders (as defined below) of the purchase, ownership and disposition of our Common Stock sold pursuant to this prospectus supplement, but does not purport to be a complete analysis of all potential tax effects. The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local or non-U.S. tax laws are not discussed. This discussion is based on the Internal Revenue Code of 1986, as amended, or the "Code," Treasury regulations promulgated or proposed thereunder, or "Treasury Regulations," judicial decisions, and published rulings and administrative pronouncements of the U.S. Internal Revenue Service, or the "IRS," in each case as in effect as of the date hereof. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect a Non-U.S. Holder. We have not sought and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance the IRS or a court will not take a position contrary to those discussed below regarding the tax consequences of the purchase ownership, and disposition of our Common Stock.

This discussion is limited to Non-U.S. Holders that hold our Common Stock as a "capital asset" within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all U.S. federal income tax consequences relevant to a Non-U.S. Holder's particular circumstances, including the impact of the Medicare contribution tax on net investment income. In addition, it does not address consequences relevant to persons subject to special rules, including, without limitation:

• U.S. expatriates and former citizens or long-term residents of the United States;

• persons subject to the alternative minimum tax;

• persons holding our Common Stock as part of a hedge, straddle, or other risk reduction strategy or as part of a conversion
transaction or other integrated investment;

• banks, insurance companies, and other financial institutions;

• real estate investment trusts or regulated investment companies;

• brokers, dealers, or traders in securities;

• "controlled foreign corporations," "passive foreign investment companies," each as defined in the
Code, and corporations that accumulate earnings to avoid U.S. federal income tax;

• partnerships or other entities or arrangements treated as partnerships for U.S. federal income tax purposes (and investors
therein);

• tax-exempt entities or governmental organizations;

• persons deemed to sell our Common Stock under the constructive sale provisions of the Code;

• persons who hold or receive our Common Stock pursuant to the exercise of any employee stock option or otherwise as
compensation;

• persons subject to the special tax accounting rules under Section 451(b) of the Code;

• persons that own, or are deemed to own, more than 5% of our Common Stock (except to the extent specifically set forth
below);

• "qualified foreign pension funds," within the meaning of Section 897(l)(2) of the Code, and entities all of the
interests of which are held by qualified foreign pension funds; and

• tax-qualified retirement plans.

------

##### [**Table of Contents**](#toc)
If any partnership or other entity or arrangement classified or treated as a partnership for U.S. federal income tax purposes holds our Common Stock, the tax treatment of a partner in the partnership will depend on the status of the partner, the activities of the partnership and certain determinations made at the partner level. Accordingly, such partnerships holding our Common Stock and partners in such partnerships should consult their tax advisors regarding the U.S. federal income tax consequences to them of the purchase, ownership and disposition of our Common Stock.

THIS DISCUSSION IS FOR INFORMATIONAL PURPOSES ONLY AND IS NOT TAX ADVICE. INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP, AND DISPOSITION OF OUR COMMON STOCK ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL, OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

**Definition of a Non-U.S. Holder** 

For purposes of this discussion, a "Non-U.S. Holder" is any beneficial owner of our Common Stock that is neither a "United States person" (as defined below) nor a partnership or other entity or arrangement treated as a partnership for U.S. federal income tax purposes. A United States person is any person that, for U.S. federal income tax purposes, is or is treated as any of the following:

• an individual who is a citizen or resident of the United States;

• a corporation, or an entity treated as a corporation for U.S. federal income tax purposes, created or organized under the
laws of the United States, any state thereof, or the District of Columbia;

• an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

• a trust that (1) is subject to the primary supervision of a U.S. court and the control of one or more "United
States persons" (within the meaning of Section 7701(a)(30) of the Code), or (2) has a valid election in effect to be treated as a United States person for U.S. federal income tax purposes.

**Distributions** 

If we make distributions of cash or property on our Common Stock, such distributions will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Amounts not treated as dividends for U.S. federal income tax purposes will constitute a non-taxable return of capital and first be applied against and reduce a Non-U.S. Holder's adjusted tax basis in its Common Stock, but not below zero. Any excess will be treated as capital gain and will be treated as described below under "Sale or Other Taxable Disposition."

Subject to the discussion below on effectively connected income, backup withholding, and the Foreign Account Tax Compliance Act, dividends paid to a Non-U.S. Holder will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividends (or such lower rate specified by an applicable income tax treaty, provided the Non-U.S. Holder furnishes to the applicable withholding agent prior to the payment of dividends a valid IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) certifying qualification for the lower treaty rate). A Non-U.S. Holder that does not timely furnish the required documentation, but that qualifies for a reduced treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. Non-U.S. Holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

------

##### [**Table of Contents**](#toc)
If dividends paid to a Non-U.S. Holder are effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States, the Non-U.S. Holder will be exempt from the U.S. federal withholding tax described above, unless an applicable income tax treaty provides otherwise. To claim the exemption, the Non-U.S. Holder must furnish to the applicable withholding agent a valid IRS Form W-8ECI, certifying that the dividends are effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States.

Any such effectively connected dividends generally will be subject to U.S. federal income tax on a net income basis at the regular rates applicable to a United States person. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on its effectively connected earnings and profits (as adjusted for certain items), which will include such effectively connected dividends. Non-U.S. Holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules.

**Sale or other taxable disposition** 

Subject to the discussion below on backup withholding and the Foreign Account Tax Compliance Act, a Non-U.S. Holder generally will not be subject to U.S. federal income tax on any gain recognized on the sale or other taxable disposition of our Common Stock unless:

• the gain is effectively connected with the Non-U.S. Holder's conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which
such gain is attributable);

• the Non-U.S. Holder is a nonresident alien individual present in the United States for 183 days or more during the taxable
year of the disposition and certain other requirements are met; or

• our Common Stock constitutes a U.S. real property interest, or USRPI, by reason of our status as a U.S. real property
holding corporation, or USRPHC, for U.S. federal income tax purposes at any time within the shorter of (1) the five-year period preceding the Non-U.S. Holder's disposition of our Common
Stock and (2) the Non-U.S. Holder's holding period for our Common Stock. Generally, a domestic corporation is a USRPHC if the fair market value of its USRPIs equals or exceeds 50% of the
sum of the fair market value of its worldwide real property interests and its other assets used or held for use in a trade or business.

Gain described in the first bullet point above generally will be subject to U.S. federal income tax on a net income basis at the regular rates applicable to a United States person. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on its effectively connected earnings and profits (as adjusted for certain items), which will include such effectively connected gain.

A Non-U.S. Holder described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on any gain recognized on the disposition, which gain may generally be offset by U.S. source capital losses of the Non-U.S. Holder (even though the individual is not considered a resident of the United States), provided the Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses.

With respect to the third bullet point above, we believe we currently are not, and do not anticipate becoming, a USRPHC. Because the determination of whether we are a USRPHC depends, however, on the fair market value of our USRPIs relative to the fair market value of our non-U.S. real property interests and our other business assets, there can be no assurance we currently are not a USRPHC or will not become one in the future. If it were determined that we are or were to become a USRPHC, gain recognized on the sale or other taxable disposition

------

##### [**Table of Contents**](#toc)
by a Non-U.S. Holder of our Common Stock will not be subject to U.S. federal income tax if our Common Stock is "regularly traded on an established securities market," as defined by applicable Treasury Regulations, and such Non-U.S. Holder owned, actually and constructively, 5% or less of our Common Stock throughout the shorter of the five-year period ending on the date of the sale or other taxable disposition or the Non-U.S. Holder's holding period. If we were to become a USRPHC and our Common Stock were not considered to be "regularly traded on an established securities market" during the calendar year in which the relevant disposition by a Non-U.S. Holder occurs, such Non-U.S. Holder (regardless of the percentage of Common Stock owned) would be subject to U.S. federal income tax on a sale or other taxable disposition of our Common Stock, and a 15% withholding tax would apply to the gross proceeds from such disposition.

Non-U.S. Holders should consult their tax advisors regarding potentially applicable income tax treaties that may provide for different rules.

**Information reporting and backup withholding** 

Payments of dividends on our Common Stock generally will not be subject to backup withholding, provided the applicable withholding agent does not have actual knowledge or reason to know the Non-U.S. Holder is a United States person and the Non-U.S. Holder either certifies its non-U.S. status, such as by furnishing a valid IRS Form W-8BEN, W-8BEN-E, or W-8ECI, or otherwise establishes an exemption. However, information returns are required to be filed with the IRS in connection with any dividends on our Common Stock paid to the Non-U.S. Holder, regardless of whether any tax was actually withheld. In addition, proceeds of the sale or other taxable disposition of our Common Stock within the United States or conducted through certain U.S.-related brokers generally will not be subject to backup withholding or information reporting if the applicable withholding agent receives the certification described above and does not have actual knowledge or reason to know that such Non-U.S. Holder is a United States person, or the Non-U.S. Holder otherwise establishes an exemption. If a Non-U.S. Holder does not provide the certification described above or the applicable withholding agent has actual knowledge or reason to know that such Non-U.S. Holder is a United States person, payments of dividends or of proceeds of the sale or other taxable disposition of our Common Stock generally will be subject to backup withholding at a rate currently equal to 24% of the gross proceeds of such dividend, sale, or taxable disposition. Proceeds of a disposition of our Common Stock conducted through a non-U.S. office of a non-U.S. broker generally will not be subject to backup withholding or information reporting.

Copies of information returns that are filed with the IRS may also be made available under the provisions of an applicable treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides or is established.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a Non-U.S. Holder's U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

Non-U.S. Holders should consult their tax advisors regarding information reporting and backup withholding.

**Additional withholding tax on payments made to foreign accounts** 

Withholding taxes may be imposed under Sections 1471 through 1474 of the Code (such Sections commonly referred to as the Foreign Account Tax Compliance Act ("FATCA")) on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities, whether such recipients are the beneficial owner or an intermediary. Specifically, a 30% withholding tax may be imposed on dividends on, or gross proceeds from the sale or other disposition of, our Common Stock paid to a "foreign financial institution" or a "non-financial foreign entity" (each as defined in the Code) (including, in some cases, when such foreign

------

##### [**Table of Contents**](#toc)
financial institution or non-financial foreign entity is acting as an intermediary), unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) the non-financial foreign entity either certifies it does not have any "substantial United States owners" (as defined in the Code) or furnishes identifying information regarding each direct and indirect substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain "specified United States persons" or "United States owned foreign entities" (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to noncompliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

Under the Code, applicable Treasury Regulations and administrative guidance, withholding under FATCA generally applies to payments of dividends on our Common Stock. The U.S. Department of the Treasury released proposed regulations (which may be relied upon by taxpayers until final regulations are issued), which eliminate FATCA withholding on the gross proceeds from a sale or other disposition of our Common Stock. Accordingly, FATCA withholding on the gross proceeds from a sale or other disposition of our Common Stock is not currently expected to apply.

Prospective investors should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in our Common Stock.

**THE COMPANY** 

Amkor is one of the world's leading providers of outsourced semiconductor packaging and test services. Amkor was a pioneer in the outsourcing of semiconductor packaging and test services, and over the years we have built a leading position by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Designing and developing innovative packaging and test technologies focused on advanced packaging solutions in
high growth markets, including artificial intelligence;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Building expertise in high-volume manufacturing processes and developing a reputation for high quality and solid
execution;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Cultivating long-standing relationships with our customers, which include many of the world's leading
semiconductor companies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Collaborating with customers, foundries, original equipment manufacturers ("OEMs") and equipment and
material suppliers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Focusing on strategic end markets that offer solid growth potential;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Providing a geographically diverse operating base with manufacturing facilities in multiple countries across Asia
and Europe; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Developing a competitive cost structure through disciplined capital investment.

Our packaging and test services are designed to meet application and chip-specific requirements, including: the required type of interconnect technology; size; thickness; and electrical, mechanical and thermal performance. We provide turnkey packaging and test services including semiconductor wafer bump, wafer probe, wafer back-grind, package design, packaging, system-level and final test and drop shipment services. Our customers use us for one or more of these services.

We provide our services to integrated device manufacturers ("IDMs"), "fabless" semiconductor companies, OEMs and contract foundries. IDMs generally design, manufacture, package and test semiconductors in their own facilities. However, the availability of technologically advanced outsourced manufacturing services has encouraged IDMs to outsource a portion of their manufacturing. By offering a broad package portfolio, Amkor allows IDMs to outsource packaging and test services and focus their investments on core competencies such as silicon fabrication. Fabless semiconductor companies do not have factories. They focus exclusively on semiconductor design and outsource virtually every step of the manufacturing process, utilizing contract foundries to manufacture their semiconductors in wafer form and companies such as Amkor for their packaging and test needs. Some companies will engage a contract foundry to manage the complete semiconductor manufacturing process, and, in turn, the contract foundry will outsource some of its packaging and test needs.

**USE OF PROCEEDS** 

Except as otherwise provided in the applicable prospectus supplement, we intend to use the net proceeds from sales of the securities for general corporate purposes, which may include reducing or refinancing our outstanding indebtedness, increasing our working capital or financing acquisitions and capital expenditures. We may temporarily invest funds that are not immediately needed for these purposes in marketable securities, including short term investments.

In the event of the liquidation, dissolution or winding up of the Company, the holders of our common stock are entitled to share ratably in all assets legally available for distribution after payment of all debts and other liabilities and subject to the prior rights of any holders of any preferred stock then outstanding.

*Composition of the Board of Directors; Election of Directors; Vacancies* 

Our board of directors consists of one or more members, and the number of directors is determined from time to time by the board of directors. Our board of directors is not classified. The directors are elected by our stockholders at each annual meeting, and each director holds office until his or her successor is elected and qualified or until such director's earlier resignation or removal. Any newly created directorship or any vacancy occurring in the board of directors for any cause may be filled by a majority of the remaining members of the board of directors, although such majority is less than a quorum, or by a sole remaining director, or by a plurality of the votes cast at a meeting of stockholders, and each director so elected will hold office until the expiration of the term of office of the director whom he or she has replaced or until his or her successor is elected and qualified.

*Other Matters* 

All issued and outstanding shares of our common stock are fully paid and nonassessable. The holders of our common stock have no preemptive, conversion or exchange rights.

The preferred stock will be issued under a certificate of designations relating to each series of preferred stock and is also subject to our Charter.

The transfer agent for each series of preferred stock and any exchange on which we plan to list a series of preferred stock will be described in the applicable prospectus supplement.

**Certain Anti-Takeover Effects** 

Certain provisions of the DGCL and our Charter and Bylaws could have certain anti-takeover effects and may delay, deter or prevent a tender offer or takeover attempt that a stockholder might consider to be in its best interests.

*Additional Authorized Shares of Capital Stock* 

The additional shares of our authorized common stock and the authorized preferred stock available for issuance under our Charter may be issued without stockholder approval, subject to the requirements prescribed by applicable law and the Nasdaq Global Select Market, and may be issued at such times, under such circumstances, and with such terms and conditions as to impede a change in control.

*Delaware Business Combination Statute* 

As a Delaware corporation, we are subject to Section 203 of the DGCL. In general, Section 203 of the DGCL provides that we may not engage in certain "business combinations" with any "interested stockholder" for a three-year period following the time that such stockholder became an interested stockholder unless:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• prior to such time, our board of directors approved either the business combination or the transaction which
resulted in the stockholder becoming an interested stockholder;

------

##### [**Table of Contents**](#toc)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the
interested stockholder owned at least 85% of our voting stock outstanding at the time the transaction commenced, excluding for purposes of determining the voting stock outstanding those shares owned (i) by persons who are directors and also
officers, and (ii) employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• at or subsequent to such time, the business combination is approved by our board of directors and authorized at
an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least two-thirds of the outstanding voting stock not owned by the interested stockholder.

Generally, a "business combination" includes a merger, asset or stock sale or other transaction resulting in a financial benefit to the interested stockholder. Subject to certain exceptions, an "interested stockholder" is a person who or which (i) beneficially owns 15% or more of the outstanding voting stock of the corporation, or (ii) any person affiliated or associated with or controlling or controlled by the corporation that was the owner of 15% or more of the outstanding voting stock of the corporation at any time within the three-year period immediately prior to the date of determination if such person is an interested stockholder, and the affiliates and associates of such person.

##### [**Table of Contents**](#toc)
**DESCRIPTION OF DEBT SECURITIES** 

The following description outlines certain general terms and provisions of our debt securities and the related indenture. The debt securities will be issued in one or more series under an indenture, to be entered into between us and U.S. Bank Trust Company, National Association, as trustee (as amended and supplemented from time to time, the "indenture"), or any successor trustee, the form of which is attached as an exhibit to the registration statement to which this prospectus relates. When we offer to sell a particular series of debt securities, we will describe the specific terms of that series in one or more prospectus supplements and such description will supplement and, to the extent inconsistent with any portion of the description of our debt securities and the indenture contained in this prospectus, supersede the applicable portion of the description contained in this prospectus.

The indenture is subject to any amendments or supplements we may enter into from time to time as permitted under the indenture. We will file any amendments or supplements to the indenture as exhibits to a Report on Form 8-K or a post-effective amendment to the registration statement to which this prospectus relates.

The statements herein relating to the debt securities and the indenture are summaries and are subject to and qualified in its entirety by reference to the detailed provisions of the debt securities and the indenture. The descriptions set forth in this prospectus do not restate the indenture and do not contain all the information you may find useful. We urge you to read the indenture because it, and not the summary set forth in this prospectus or contained in any applicable prospectus supplement, defines your rights as a holder of the debt securities. Whenever we refer to particular sections of or defined terms in the indenture, those sections and definitions are incorporated by reference. The indenture is subject to and governed by the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act").

As used in this description of debt securities, "we," "our," "us," "Amkor" and the "Company" refer solely to Amkor Technology, Inc. and not to any of our subsidiaries.

**General** 

The debt securities will be general unsecured obligations of the Company.

We will describe in one or more prospectus supplements the terms of the series of debt securities that we may offer and the supplemental indenture relating to such series of debt securities. These terms will include, without limitation, the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The title and ranking of the series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The price or prices at which the securities of the series will be issued;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any limit upon the aggregate principal amount of the debt securities of the series which may be issued;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the date or dates on which the principal and premium, if any, of the debt securities of the series shall be
payable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the rate or rates, or the method of determination thereof, at which the debt securities of the series shall bear
interest, the date or dates from which that interest shall accrue, the interest payment dates on which that interest shall be payable and the record dates for the determination of holders to whom interest is payable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if applicable, our obligation to redeem, purchase or repay debt securities of the series pursuant to any sinking
fund or analogous provisions or at the option of a holder thereof and the price at which or process by which and the period or periods within which and the terms and conditions upon which debt securities of the series would be redeemed, purchased or
repaid, in whole or in part, pursuant to such obligation;

##### [**Table of Contents**](#toc)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if other than in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof, the
denominations in which debt securities of the series shall be issuable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if other than U.S. dollars, the currency of the debt securities of the series and the currency in which payments
on the debt securities of the series shall be payable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if applicable, the manner in which the amounts of payment of principal of and interest, if any, on the securities
will be determined, if such amounts may be determined by reference to an index based on a currency or currencies or by reference to a commodity, commodity index, stock exchange index or other index;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the provisions, if any, relating to any security for or guarantees of the securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any additions to, deletions of or changes in the events of default which apply to the securities and any change
in the right of the trustee or the holders of such securities to declare the principal amount thereof due and payable pursuant to the indenture and any change in the circumstances under which the securities shall become due and payable automatically
pursuant to the indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any additions to, deletions of or changes in the covenants which apply to the securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if the securities will be convertible into or exchangeable for shares of common stock, preferred stock or other
securities of the Company or any other person, the terms and conditions upon which the securities will be so convertible or exchangeable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if the securities will not be senior securities, whether the securities will be senior subordinated, subordinated
or junior subordinated debt securities (or will have some other subordinated ranking) and, in that case, a description of the subordination terms thereof;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the trustee, if different from the existing trustee under an indenture; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any other terms of the series.

Unless otherwise specified in any applicable prospectus supplement, when we use the term "business day," we mean any calendar day that is not a Saturday, Sunday or a day on which commercial banking institutions are not required to be open for business in The City of New York, New York or, in connection with a payment, the place of payment.

Unless otherwise specified in any applicable prospectus supplement, each series of the debt securities will be issued in the form of one or more fully-registered debt securities in global form registered in the name of the nominee of The Depository Trust Company ("DTC").

The indenture will not limit the aggregate amount of debt securities that we may issue. We may issue debt securities under the indenture up to the aggregate principal amount authorized by our board of directors from time to time. In addition, the indenture does not limit our ability to incur senior debt, subordinated or secured debt, or our ability, or that of any of our existing or future subsidiaries, to incur other indebtedness and other liabilities or issue preferred stock.

We may, from time to time, without the consent of the holders of debt securities of a particular series, reopen that series of debt securities and issue additional debt securities of that series having the same ranking and the same interest rate, maturity and other terms as the debt securities of that series, except for the public offering price, the issue date and, if applicable, the initial interest payment date and initial interest accrual date. Any such additional debt securities, together with the debt securities of the same series initially offered by this prospectus and any applicable prospectus supplement, will constitute a single series of debt securities under the indenture; provided that if the additional debt securities are not fungible for U.S. federal income tax purposes with the debt securities of the same series initially offered by this prospectus and any applicable prospectus supplement, the additional debt securities will be issued under a separate CUSIP, ISIN or other identifying number, as applicable. No additional debt securities may be issued if an event of default has occurred and is continuing with respect to the series of debt securities of which those additional debt securities would be a part.

------

##### [**Table of Contents**](#toc)
Unless we inform you otherwise in the applicable prospectus supplement, the debt securities will not be listed on any securities exchange.

The trustee will initially be the registrar and paying agent for the debt securities. We will maintain an office in the continental United States where we will pay the principal of, and any premium and interest on, the debt securities and you may present the debt securities for registration of transfer and exchange. We have designated the corporate trust office of the trustee for this purpose.

**Ranking** 

Unless otherwise specified in any applicable prospectus supplement, each series of debt securities will be our direct, unsecured obligations and will rank without preference or priority among themselves and equally in right of payment with all of our existing and future unsecured and unsubordinated obligations, and senior in right of payment to all of our existing and future indebtedness that is expressly subordinated to that series of debt securities. Each series of debt securities that is unsecured will be effectively subordinated in right of payment to all of our secured indebtedness, if any, to the extent of the value of the assets securing that indebtedness.

**Certain Covenants** 

Set forth below are summaries of certain covenants in the indenture that apply to us, unless otherwise provided in an applicable prospectus supplement. However, the indenture will not significantly limit our operations. In particular, the indenture will not:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limit the amount or frequency of dividends that we can pay;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limit the amount of debt securities that we may issue from time to time;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limit the number of series of debt securities that we may issue from time to time;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limit or otherwise restrict the amount of indebtedness which we or our subsidiaries may incur; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• contain any covenant or other provision that is specifically intended to afford any holder of debt securities any
protection in the event of highly-leveraged transactions or similar transactions involving us or our subsidiaries.

*Consolidation, Merger and Sale of Assets* 

The indenture will provide that we will not (i) merge or consolidate with any other person or (ii) sell, convey, transfer or otherwise dispose of all or substantially all of our assets to any person (other than a subsidiary), in each case unless:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• either we are the continuing person or the successor person (if not us) is a corporation, limited liability
company or other entity that pursuant to a supplemental indenture to the indenture expressly assumes all of our obligations under the indenture and the debt securities issued and outstanding thereunder; provided that, in the event that the successor
person is not a corporation, another person that is a corporation shall expressly assume, as co-obligor with that successor person, all of our obligations under the indenture and the debt securities issued and
outstanding thereunder; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• immediately after that merger or consolidation, or that sale, conveyance, transfer or other disposition, no
default or event of default has occurred and is continuing under the indenture.

We will deliver to the Trustee prior to the consummation of the proposed transaction an officers' certificate to the foregoing effect and an opinion of counsel stating that the proposed transaction and any supplemental indenture comply with the indenture.

Notwithstanding the above, any of our subsidiaries may consolidate with, merge into or convey, transfer or lease all or any part of its properties or assets to us or any of our subsidiaries.

------

##### [**Table of Contents**](#toc)
In the event of any such merger, consolidation, sale, conveyance (other than by way of lease), transfer or other disposition, and upon any such assumption by the successor person or persons, such successor person or persons shall succeed to and be substituted for us, and may exercise every right and power of us under the indenture, with the same effect as if it or they had been named in the indenture and the debt securities as us and we shall be relieved of any further obligations under the indenture and under the debt securities issued and outstanding thereunder and the predecessor company may be dissolved, wound up and liquidated at any time thereafter.

*SEC Reports* 

Under the indenture, we will be required to deliver to the trustee, within 15 days after we file the same with the SEC, copies of the annual reports and of the information, documents and other reports that we are required to file with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act or pursuant to Section 314 of the Trust Indenture Act. Annual reports, information, documents and other reports that are filed or furnished by us with the SEC via the EDGAR system or any successor electronic delivery procedure will be deemed to be delivered to the trustee at the time those documents are filed via the EDGAR system or such successor procedure. Delivery of those reports, information and documents to the trustee is for informational purposes only, and the trustee's receipt thereof will not constitute actual or constructive notice of any information contained therein or determinable from information contained therein, including our compliance with any of our covenants in the indenture (as to which the trustee is entitled to rely conclusively upon officers' certificates). The trustee shall have no liability whatsoever to determine whether any financial information has been filed or posted by us on the EDGAR system (or any successor system) or have any duty to monitor or determine whether we have delivered the reports described hereunder or otherwise complied with our obligations under this "— Certain Covenants — SEC Reports."

**Events of Default** 

Unless otherwise provided in any applicable prospectus supplement, any of the following events will constitute an event of default under the indenture with respect to any series of debt securities:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• default in the payment of any installment of interest on that series of debt securities when due and payable, and
the continuance of that default for 30 days;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• default in the payment of the principal of, or any premium on, that series of debt securities when due and
payable (whether at maturity, upon redemption or otherwise);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• failure to observe or perform any covenant or agreement in the indenture in respect of the debt securities of
that series (other than the defaults set forth above or pursuant to a covenant or warrant included in the indenture solely for the benefit of a series of securities other than that series), which failure continues for 90 days after receipt of
written notice to us from the trustee or to us and the trustee from the holders of at least 30% of the outstanding aggregate principal amount of that series of debt securities as provided in the indenture, in each case, specifying such default or
breach, requiring us to remedy the same and stating that such notice is a "Notice of Default" under the indenture; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Specified events relating to the bankruptcy, insolvency, reorganization or receivership of us.

If an event of default arising from specified events of the bankruptcy, insolvency, reorganization or receivership of us occurs with respect to a series of debt securities, the principal amount of all outstanding debt securities of that series will become due and payable immediately, without further action or notice on the part of the holders of the debt securities of that series or the trustee.

If any other event of default with respect to a series of debt securities occurs, the trustee or the holders of not less than 30% in aggregate principal amount of the outstanding debt securities of that series may declare the principal amount of the debt securities of that series to be due and payable immediately, by a notice in writing to us, and to the trustee if given by holders. Upon any such declaration, the principal amount of that series of debt securities will become immediately due and payable.

------

##### [**Table of Contents**](#toc)
However, at any time after a declaration of acceleration has been made, but before a judgment or decree for payment of the money due has been obtained, the holders of a majority in aggregate principal amount of the outstanding debt securities of that series of debt securities may, subject to conditions specified in the indenture, rescind and annul that declaration or acceleration and its consequences.

The trustee will be under no obligation to exercise any of its rights or powers under the indenture at your request, order or direction, unless you have offered, and, if requested, provided to the trustee security or indemnity satisfactory to the trustee. Subject to the provisions for the security or indemnification of the trustee and otherwise in accordance with the conditions specified in the indenture, the holders of a majority in aggregate principal amount of outstanding debt securities of any series issued under the indenture have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee in connection with the debt securities of such series.

**Notice of Default** 

The trustee will, within 90 days after a responsible officer of the trustee obtains actual knowledge of the occurrence of a default with respect to a series of debt securities, send to the holders of such debt securities notice of such default relating to such series of debt securities, unless such default has been cured or waived. However, the Trust Indenture Act and the indenture permit the trustee to withhold notices of defaults (except for certain payment defaults) if the trustee in good faith determines the withholding of such notices is in the interests of the holders.

We will furnish the trustee with an annual officers' certificate certifying as to our compliance with the conditions and covenants in the indenture.

**Legal Proceedings and Enforcement of Right of Payment** 

You will not have any right to institute any proceeding under or with respect to the indenture or for any remedy under the indenture, unless you have previously given to the trustee written notice of a continuing event of default with respect to the debt securities you hold. In addition, the holders of at least 30% in aggregate principal amount of the outstanding debt securities of a series must have made written request, and offered to the trustee such indemnity as it may require, to institute that proceeding as trustee, and, within 90 days following the receipt of that notice, request and offer of indemnity, the trustee must not have received from the holders of a majority in principal amount of the outstanding debt securities of that series a direction inconsistent with that request, and must have failed to institute the proceeding. However, you will have an absolute right to receive payment of the principal of, and any premium or interest on, the debt securities you hold at the place, time, rates and in the currency expressed in the indenture and the debt securities you hold and to institute a suit for the enforcement of that payment.

**Modification of Indenture** 

We may enter into supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of the indenture with respect to one or more series of debt securities issued thereunder with the consent of holders of a majority in aggregate principal amount of the outstanding debt securities of all such series affected by such modification or amendment, voting as a single class. However, the consent of each holder affected is required for any amendment to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• change the stated maturity of principal of, or any installment of principal of or interest on, any debt security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in the case of any series of subordinated debt securities, modify the subordination provisions of that series of
subordinated debt securities in a manner materially adverse to the holders of that series of subordinated debt securities;

------

##### [**Table of Contents**](#toc)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• adversely affect the right of any holder of the debt securities to convert or exchange any debt security into or
for our common stock or other securities in accordance with the terms of such security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduce the rate of or extend the time for payment of interest, if any, on any debt security or alter the manner
of calculation of interest payable on any debt security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduce the principal amount or premium, if any, on any debt security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• make the principal of, and any premium or interest on, any debt security payable in a different currency than
that stated in the debt security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduce the percentage in aggregate principal amount of any series of outstanding debt securities, the
holders of which are required to consent to any supplemental indenture or to any waiver of any past default or event of default;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• change any place of payment where the debt securities or interest thereon is payable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• modify the interest rate reset provision of any debt security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• impair the right of any holder of the debt securities to receive payment of the principal of, and any premium or
interest on, any debt securities on or after the respective due dates for such principal, premium or interest, or to institute suit for the enforcement of any such payment, or reduce the amount of the principal of an original issue discount security
that would be due and payable upon an acceleration of the maturity thereof, or adversely affect the right of repayment, if any, at the option of the holder, or extend the time for, or reduce the amount of, any payment to any sinking fund or
analogous obligation relating to any debt security; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• modify provisions of the indenture relating to waiver of defaults or amendment of the indenture, except to
increase the percentage in aggregate principal amount of debt securities whose holders must consent to an amendment or to provide that certain other provisions of the indenture cannot be modified or waived without the consent of the holder of
each outstanding debt security affected by the modification or waiver.

Notwithstanding the foregoing, holders of the debt securities of any series shall vote as a separate class with respect to modifications or amendments that affect only the debt securities of that series, and the holders of other series of debt securities shall not have any voting rights with respect to those matters as they relate to the debt securities of that series.

In addition, we and the trustee may enter into supplemental indentures without the consent of the holders of the debt securities of any series for one or more of the following purposes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to evidence that another person has become our successor and/or to add a co-obligor under the provisions of the indenture relating to mergers, consolidations, sales, conveyances, transfers or other dispositions of assets described under "— Certain Covenants —
Consolidation, Merger and Sale of Assets" in this prospectus, and that the successor or successors assume our covenants, agreements and obligations in the indenture and in the debt securities issued thereunder;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to add to our covenants further covenants, restrictions, conditions or provisions for the protection of the
holders of all or any series of the debt securities as our board of directors shall consider to be for the protection of the holders of those debt securities, and to make a default in any of these additional covenants, restrictions, conditions or
provisions a default or an event of default under the indenture; provided, however, that in respect of any such additional covenant, restriction, condition or provision, such supplemental indenture may provide for a particular period of grace after
default (which period may be shorter or longer than that allowed in the case of other defaults) or may provide for an immediate enforcement upon such default or may limit the remedies available to the trustee upon such default;

------

##### [**Table of Contents**](#toc)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to conform the terms of any series of debt securities to the description thereof in the applicable prospectus
supplement; provided that any amendment made solely to conform the provisions of the indenture to the description of the debt securities contained in this prospectus or any applicable prospectus supplement or other offering document pursuant to
which the debt securities were sold will not be deemed to adversely affect the interests of the holders of that series of debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to establish the forms or terms of debt securities of any series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to cure any ambiguity, to cure any mistake, to correct or supplement any provisions that may be defective or
inconsistent with any other provision or to make such other provisions in regard to matters or questions arising under the indenture that do not adversely affect the interests of the holders of such series of debt securities in any material respect;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to modify or amend the indenture to permit the qualification of the indenture or any supplemental indentures
under the Trust Indenture Act as then in effect;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to provide for the issuance of additional debt securities of any series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to provide for the exchange of any debt securities in global form represented by one or more global certificates
for debt securities of the same series issued under the indenture in definitive certificated form in the circumstances permitted by the terms of the indenture and those debt securities, and to make all appropriate changes to the indenture for that
purpose;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to add to, change or eliminate any of the provisions of the supplemental indentures in respect of one or more
series of debt securities; provided that any such addition, change or elimination (i) shall not apply to, or modify the rights of any holder of, any debt security of any series created prior to the execution of such supplemental indentures or
(ii) shall become effective only when no debt securities of any series created prior to the execution of such supplemental indentures are outstanding;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to add guarantees with respect to any series of debt securities or to secure any series of debt securities; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to evidence and provide for the acceptance of appointment by a successor or separate trustee with respect to the
debt securities of any one or more series.

**Defeasance of Indenture** 

We have the right to terminate all of our obligations with respect to a series of debt securities under the covenants described under "— Certain Covenants" in this prospectus and under such other covenants for that series as may be established and specified in the future in accordance with the terms of the indenture and to provide that any event of default expressed to be subject to covenant defeasance under the indenture shall no longer constitute an event of default under the indenture with respect to that series of debt securities, following irrevocably depositing in trust with the trustee, as trust funds solely for the benefit of holders of debt securities of that series, money in an amount sufficient, U.S. government obligations or foreign governments obligations (in the case of debt securities denominated in a foreign currency) the scheduled payments of principal and interest on which shall be sufficient, or a combination thereof sufficient (which, in the case of U.S. government obligations or foreign government obligations, shall be determined in the opinion of an internationally recognized firm of independent accountants expressed in a written certificate delivered to the trustee), without consideration of any reinvestment of interest, to pay principal of, and any premium or interest on, the debt securities of that series to their maturity or redemption, as the case may be, and complying with certain other conditions, including delivery to the trustee of an opinion of counsel, to the effect that beneficial owners will not recognize income, gain or loss for U.S. federal income tax purposes as a result of our exercise of such right and will be subject to federal income tax on the same amount and in the same manner and at the same times as would have been the case otherwise.

------

##### [**Table of Contents**](#toc)
In addition, we have the right at any time to terminate all of our obligations under the indenture with respect to any series of debt securities issued thereunder, other than:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) your right to receive, solely from the trust fund described below, payment of the principal of and each installment, if any, of principal of and interest on, the outstanding debt of such series on the stated maturity of such principal or installment of principal or interest due; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) certain obligations relating to the defeasance trust and obligations to register the transfer or exchange of the debt securities, to replace mutilated, lost or stolen debt securities, to maintain a registrar and paying agent in respect of the debt securities, to pay compensation to, and expenses of, and indemnify, the trustee, and with respect to the resignation or removal of the trustee,

following irrevocably depositing in trust with the trustee, as trust funds solely for the benefit of holders of debt securities of that series, money in an amount sufficient, U.S. government obligations or foreign governments obligations (in the case of debt securities denominated in a foreign currency) the scheduled payments of principal and interest on which shall be sufficient, or a combination thereof sufficient, (which, in the case of U.S. government obligations or foreign government obligations, shall be determined in the opinion of an internationally recognized firm of independent accountants expressed in a written certificate delivered to the trustee), without consideration of any reinvestment of interest, to pay principal of, and any premium or interest on, the debt securities of such series to their maturity or redemption, as the case may be, and complying with certain other conditions, including delivery to the trustee of a ruling received from the Internal Revenue Service or an opinion of counsel to the effect that beneficial owners will not recognize income, gain or loss for U.S. federal income tax purposes as a result of our exercise of such right and will be subject to federal income tax on the same amount and in the same manner and at the same times as would have been the case otherwise, which, in the case of an opinion of counsel, is based upon a change in law after the date of the indenture.

**Satisfaction and Discharge** 

The indenture will generally cease to be of any further effect with respect to any series of debt securities issued thereunder (except with respect to provisions that, by their terms, survive), if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• either (i) we have delivered to the trustee for cancellation all outstanding debt securities of that series
(with certain limited exceptions), or (ii) all of the outstanding debt securities of that series not previously delivered to the trustee for cancellation (A) have become due and payable, (B) are by their terms to become due and
payable at their stated maturity within one year, or (C) have been called for redemption within one year under arrangements satisfactory to the trustee, and we have irrevocably deposited with the trustee in trust, funds sufficient to pay and
discharge the entire indebtedness on such securities at maturity or upon redemption all of the outstanding debt securities of that series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• we have paid or caused to be paid all other sums then payable under the indenture by us; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• we have delivered an officers' certificate and an opinion of counsel to the trustee, each stating that all
conditions precedent to satisfaction and discharge have been satisfied.

Subject to applicable law and the indenture, any monies, U.S. government obligations and foreign government obligations (in the case of debt securities denominated in a foreign currency) deposited with the trustee for payment of principal of, and any premium or interest on, the debt securities of any series and not applied but remaining unclaimed by the holders of the debt securities of that series for two years after the date upon which the principal of, and any premium or interest on, the debt securities of such series, as the case may be, shall have become due and payable, shall be repaid to us by the trustee upon request by the Company. Thereafter, the holders of the debt securities of that series may look only to us for payment thereof.

**Miscellaneous Provisions** 

The indenture will provide that certain debt securities, including those debt securities owned by us or any other obligor of the applicable debt securities or any person directly or indirectly controlled by or under direct or

------

##### [**Table of Contents**](#toc)
indirect common control with us or any other obligor of the applicable debt securities, will not be deemed to be "outstanding" in determining whether the holders of the requisite aggregate principal amount of the outstanding debt securities of a particular series have concurred in or given or taken any request, demand, authorization, direction, notice, consent, waiver or other action under the indenture as of any date, except that, in determining whether the trustee shall be protected in relying on any request, demand, authorization, direction, notice, consent, waiver or other action, only debt securities that a responsible officer of the trustee has actual knowledge to be so owned shall be so disregarded.

We will be entitled to set any day as a record date for the purpose of determining the identity of holders of debt securities of any series issued under the indenture entitled to vote or consent (or to revoke any vote or consent) to any action under the indenture, in the manner and subject to the limitations provided in the indenture.

**Resignation and Removal of a Trustee** 

The trustee may resign under the indenture at any time by giving written notice thereof to us.

Under certain circumstances, we may remove the trustee and appoint a successor trustee. The trustee may also be removed by act of the holders of a majority in aggregate principal amount of the then outstanding debt securities of one or more series issued and outstanding under the indenture.

No resignation or removal of a trustee and no appointment of a successor trustee will become effective until the acceptance of appointment by a successor trustee in accordance with the requirements of the indenture.

**Governing Law and Consent to Jurisdiction** 

The indenture and any debt securities issued under the indenture, and any claim, controversy or dispute arising under or related to the indenture and the debt securities will be, governed by and construed in accordance with the laws of the State of New York.

We will agree that any legal action or proceeding arising out of or based upon the indenture, the securities or the transactions contemplated thereby may be instituted in any U.S. federal or New York State court located in the City of New York and any appellate court thereof, and we have irrevocably submitted to the non-exclusive jurisdiction of any such court in any such suit, action or proceeding and waive, to the fullest extent permitted by law, the defense of an inconvenient forum to the maintenance of such action or proceeding and any objection to the laying of venue in such courts.

**DESCRIPTION OF WARRANTS** 

The following description outlines some of the general terms and provisions of the warrants that we may offer under this prospectus. While the terms summarized below will apply generally to any warrants that we may offer, we will describe the particular terms of any series of warrants in more detail in the applicable prospectus supplement. If we so indicate in the prospectus supplement, the terms of any warrants offered under that prospectus supplement may differ from the terms described below. The following description and any description of the warrants in a prospectus supplement may not be complete and is subject to and qualified in its entirety by reference to the terms and provisions of the warrant agreement, a form of which will be filed as an exhibit to the registration statement that contains this prospectus or as an exhibit to a current report on Form 8-K.

**General** 

We may issue warrants for the purchase of common stock, preferred stock and/or debt securities in one or more series. We may issue warrants independently or together with common stock, preferred stock and/or debt securities, and the warrants may be attached to or separate from these securities.

We will evidence each series of warrants by warrant certificates that we may issue under a separate agreement. We may enter into the warrant agreement with a warrant agent. We will indicate the name and address of any such warrant agent in the applicable prospectus supplement relating to a particular series of warrants.

We will describe in the applicable prospectus supplement the terms of the series of warrants, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the offering price and aggregate number of warrants offered;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the currency for which the warrants may be purchased, if not U.S. dollars;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if applicable, the designation and terms of the securities with which the warrants are issued and the number of
warrants issued with each such security or each principal amount of such security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• if applicable, the date on and after which the warrants and the related securities will be separately
transferable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• in the case of warrants to purchase debt securities, the principal amount of debt securities purchasable upon
exercise of one warrant and the price at, and currency, if not U.S. dollars, in which, this principal amount of debt securities may be purchased upon such exercise;

**Exercise of Warrants** 

Each warrant will entitle the holder to purchase the securities that we specify in the applicable prospectus supplement at the exercise price that we describe in the applicable prospectus supplement. Unless we otherwise specify in the applicable prospectus supplement, holders of the warrants may exercise the warrants at any time up to 5:00 P.M. Eastern Time on the expiration date that we set forth in the applicable prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.

Warrants may be exercised as set forth in the applicable prospectus supplement. Upon receipt of the required payment and the warrant certificate properly completed and duly executed at the corporate trust office of the warrant agent or any other office indicated in the applicable prospectus supplement, we will issue and deliver the securities purchasable upon such exercise. If fewer than all of the warrants represented by the warrant certificate are exercised, then we will issue a new warrant certificate for the remaining amount of warrants. If we so indicate in the applicable prospectus supplement, holders of the warrants may surrender securities as all or part of the exercise price for warrants.

**DESCRIPTION OF UNITS** 

The following description outlines some of the general terms and provisions of the units that we may offer under this prospectus. While the terms summarized below will apply generally to any units that we may offer, we will describe the particular terms of any units in more detail in the applicable prospectus supplement. If we so indicate in the prospectus supplement, the terms of any units offered under that prospectus supplement may differ from the terms described below. The following description and any description of units in the applicable prospectus supplement does not purport to be complete and is subject to and is qualified in its entirety by reference to the unit agreement and, if applicable, collateral arrangements and depository arrangements relating to such units that we will file with the SEC as an exhibit to the registration statement that contains this prospectus or as an exhibit to a current report on Form 8-K.

We may issue units comprised of one or more of the other securities described in this prospectus in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date or occurrence.

The applicable prospectus supplement may describe:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the designation and terms of the units and of the securities comprising the units, including whether and under
what circumstances those securities may be held or transferred separately;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities
comprising the units; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether the units will be issued in fully-registered or global form.

**PLAN OF DISTRIBUTION** 

We may sell the securities described in this prospectus through underwriters or dealers, through agents, or directly to one or more purchasers or through a combination of these methods. The applicable prospectus supplement will describe the terms of the offering of the securities, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the name or names of any underwriters and, if required, any dealers or agents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the purchase price of the securities and the proceeds we will receive from the sale;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any discounts or concessions allowed or reallowed or paid to dealers; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any securities exchange or market on which the securities may be listed.

We may distribute the securities from time to time in one or more transactions at:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a fixed price or prices, which may be changed;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• market prices prevailing at the time of sale;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• varying prices determined at the time of sale related to such prevailing market prices; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• negotiated prices.

Offerings of our equity securities pursuant to this prospectus may also be made into an existing trading market for such securities in transactions at other than a fixed price, either:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• on or through the facilities of any national securities exchange or quotation service on which such securities
may be listed or quoted at the time of sale; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to or through a market maker otherwise than on such exchanges.

Such at-the-market offerings will be conducted by underwriters acting as our principal or agent, who may also be third-party sellers of securities as described above.

Only underwriters named in the prospectus supplement will be underwriters of the securities offered by the prospectus supplement. If we use underwriters in the sale, they will acquire the securities for their own account and may resell the securities from time to time in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. We may offer the securities to the public through underwriting syndicates represented by managing underwriters or by underwriters without a syndicate. Any public offering price and any discounts or concessions allowed or reallowed or paid to dealers may change from time to time.

We may sell the securities directly. In this case, no underwriters or agents would be involved. We may also sell the securities through agents we designate from time to time. We will name any agent involved in the offering and sale of securities and we will describe any commissions we will pay the agent in the prospectus supplement.

We may authorize agents or underwriters to solicit offers by institutional investors to purchase securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. We will describe the conditions to these contracts and the commissions we must pay for solicitation of these contracts in the prospectus supplement.

In addition, we may sell some or all of the securities covered by this prospectus through:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• purchases by a dealer, as principal, who may then resell those securities to the public for its account at
varying prices determined by the dealer at the time of resale;

------

##### [**Table of Contents**](#toc)
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• block trades in which a dealer will attempt to sell as agent, but may position or resell a portion of the block,
as principal, in order to facilitate the transaction; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ordinary brokerage transactions and transactions in which a broker-dealer solicits purchasers.

We will include in the applicable prospectus supplement the names of any dealers and the terms of the transaction.

In connection with the sale of the securities, underwriters, dealers or agents may receive compensation from us or from purchasers of the securities for whom they act as agents in the form of discounts, concessions or commissions. Underwriters may sell the securities to or through dealers, and those dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters or commissions from the purchasers for whom they may act as agents. Underwriters, dealers and agents that participate in the distribution of the securities, and any institutional investors or others that purchase securities directly and then resell the securities, may be deemed to be underwriters, and any discounts or commissions received by them from us and any profit on the resale of the securities by them may be deemed to be underwriting discounts and commissions under the Securities Act.

We may provide agents and underwriters with indemnification against particular civil liabilities, including liabilities under the Securities Act, or contribution with respect to payments that the agents or underwriters may make with respect to such liabilities. Agents and underwriters may engage in transactions with, or perform services for, us in the ordinary course of business. In addition, we may enter into derivative transactions with third parties (including the writing of options), or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If the applicable prospectus supplement indicates, in connection with such a transaction, the third parties may, pursuant to this prospectus and the applicable prospectus supplement, sell securities covered by this prospectus and the applicable prospectus supplement. If so, the third party may use securities borrowed from us or others to settle such sales and may use securities received from us to close out any related short positions. We may also loan or pledge securities covered by this prospectus and the applicable prospectus supplement to third parties, who may sell the loaned securities or, in an event of default in the case of a pledge, sell the pledged securities pursuant to this prospectus and the applicable prospectus supplement. The third party in such sale transactions will be an underwriter and will be identified in the applicable prospectus supplement or in a post-effective amendment.

Offered securities may also be offered and sold, if so indicated in the applicable prospectus supplement, in connection with a remarketing upon their purchase, in accordance with a redemption or repayment pursuant to their terms, or otherwise, by one or more remarketing firms, acting as principals for their own accounts or as agents for us. Any remarketing firm will be identified and the terms of its agreements, if any, with us and its compensation will be described in the applicable prospectus supplement.

To facilitate an offering of a series of securities, persons participating in the offering may engage in transactions that stabilize, maintain, or otherwise affect the market price of the securities. This may include over-allotments or short sales of the securities, which involves the sale by persons participating in the offering of more securities than have been sold to them by us. In those circumstances, such persons would cover such over-allotments or short positions by purchasing in the open market or by exercising the over-allotment option granted to those persons. In addition, those persons may stabilize or maintain the price of the securities by bidding for or purchasing securities in the open market or by imposing penalty bids, whereby selling concessions allowed to underwriters or dealers participating in any such offering may be reclaimed if securities sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. Such transactions, if commenced, may be discontinued at any time. We make no representation or prediction as to the direction or magnitude of any effect that the transactions described above, if implemented, may have on the price of our securities.

Underwriters or agents and their affiliates may be customers of, engage in transactions with or perform services for us or our affiliates in the ordinary course of business.

Some or all of the securities that we offer through this prospectus may be new issues of securities with no established trading market. Any underwriters to whom we sell our securities for public offering and sale may make a market in those securities, but they will not be obligated to do so and they may discontinue any market making at any time without notice. Accordingly, we cannot assure you of the liquidity of, or continued trading markets for, any securities that we offer.
