Software and workloads used in performance tests may have been optimized for performance only on Intel microprocessors. Performance tests, such as SYSmark and MobileMark, are measured using specific
computer systems, components, software, operations and functions. Any change to any of those factors may cause the results to vary. You should consult other information and performance tests to assist you in fully
evaluatingyour contemplated purchases, including the performance of that product when combined with other products.

Intel® AES-NI requires a computer system with an AES-NI enabled processor, as well as non-Intel software to execute the
instructions in the correct sequence. AES-NI is available on select Intel® processors. For availability, consult your reseller
or system manufacturer. For more information, see Intel® Advanced Encryption Standard Instructions (AES-NI).
Intel® Hyper-Threading Technology (Intel® HT Technology) is available on select Intel® Core™ processors. Requires an
Intel® HT Technology-enabled system. Consult your PC manufacturer. Performance will vary depending on the specific
hardware and software used. For more information including details on which processors support Intel HT Technology, visit
http://www.intel.com/info/hyperthreading.
Software and workloads used in performance tests may have been optimized for performance only on Intel microprocessors.
Performance tests, such as SYSmark* and MobileMark*, are measured using specific computer

Risk Factors
The above statements and any others in this document that refer to plans and expectations for the third quarter, the year and the future are
forward-looking statements that involve a number of risks and uncertainties. Words such as “anticipates,” “expects,” “intends,” “plans,”
“believes,” “seeks,” “estimates,” “may,” “will,” “should” and their variations identify forward-looking statements. Statements that refer to or
are based on projections, uncertain events or assumptions also identify forward-looking statements. Many factors could affect Intel’s actual
results, and variances from Intel’s current expectations regarding such factors could cause actual results to differ materially from those
expressed in these forward-looking statements. Intel presently considers the following to be the important factors that could cause actual
results to differ materially from the company’s expectations. Demand could be different from Intel's expectations due to factors including
changes in business and economic conditions; customer acceptance of Intel’s and competitors’ products; supply constraints and other
disruptions affecting customers; changes in customer order patterns including order cancellations; and changes in the level of inventory at
customers. Uncertainty in global economic and financial conditions poses a risk that consumers and businesses may defer purchases in
response to negative financial events, which could negatively affect product demand and other related matters. Intel operates in intensely
competitive industries that are characterized by a high percentage of costs that are fixed or difficult to reduce in the short term and product
demand that is highly variable and difficult to forecast. Revenue and the gross margin percentage are affected by the timing of Intel product
introductions and the demand for and market acceptance of Intel's products; actions taken by Intel's competitors, including product offerings
and introductions, marketing programs and pricing pressures and Intel’s response to such actions; and Intel’s ability to respond quickly to
technological developments and to incorporate new features into its products. The gross margin percentage could vary significantly from
expectations based on capacity utilization; variations in inventory valuation, including variations related to the timing of qualifying products
for sale; changes in revenue levels; segment product mix; the timing and execution of the manufacturing ramp and associated costs; start-
up costs; excess or obsolete inventory; changes in unit costs; defects or disruptions in the supply of materials or resources; product
manufacturing quality/yields; and impairments of long-lived assets, including manufacturing, assembly/test and intangible assets. Intel's
results could be affected by adverse economic, social, political and physical/infrastructure conditions in countries where Intel, its customers
or its suppliers operate, including military conflict and other security risks, natural disasters, infrastructure disruptions, health concerns and
fluctuations in currency exchange rates. Expenses, particularly certain marketing and compensation expenses, as well as restructuring and
asset impairment charges, vary depending on the level of demand for Intel's products and the level of revenue and profits. Intel’s results
could be affected by the timing of closing of acquisitions and divestitures. Intel's results could be affected by adverse effects associated with
product defects and errata (deviations from published specifications), and by litigation or regulatory matters involving intellectual
property, stockholder, consumer, antitrust, disclosure and other issues, such as the litigation and regulatory matters described in Intel's SEC
reports. An unfavorable ruling could include monetary damages or an injunction prohibiting Intel from manufacturing or selling one or more
products, precluding particular business practices, impacting Intel’s ability to design its products, or requiring other remedies such as
compulsory licensing of intellectual property. A detailed discussion of these and other factors that could affect Intel’s results is included in
Intel’s SEC filings, including the company’s most recent reports on Form 10-Q, Form 10-K and earnings release.
