Safe Harbor

This presentation contains forward-looking statements, which are subject to the safe harbor provisions of the

Private Securities Litigation Reform Act of 1995. All statements other than statements of historical facts

contained in this presentation, including statements regarding our estimates of future stock-based

compensation expense, are forward-looking statements. These forward-looking statements are only

predictions and may differ materially from actual results due to a variety of factors, including variations in the

future price of our common stock as well as future grants and forfeitures of equity awards. In addition, please

note that the date of this presentation is October 23, 2012, and any forward-looking statements contained

herein are based on assumptions that we believe to be reasonable as of this date. We undertake no obligation

to update these statements as a result of new information or future events.

In addition to U.S. GAAP financials, this presentation includes certain non-GAAP financial measures. These

non-GAAP measures are in addition to, not a substitute for or superior to, measures of financial performance

prepared in accordance with U.S. GAAP. A reconciliation of non-GAAP financial measures to the corresponding

GAAP measures is provided in the appendix to this presentation. Please also see the appendix to this

Monthly Active Users (MAUs)

Please see Facebook's Form 10-Q for the quarter ended September 30, 2012 for definitions of user activity used to determine the number of our MAUs, DAUs and mobile MAUs. The number of MAUs, DAUs, and mobile MAUs do not include Instagram users unless such users would otherwise qualify as MAUs, DAUs, and mobile MAUs based on activity that is shared back to Facebook.

In June 2012, we discovered an error in the algorithm we used to estimate the geographic location of our users that affected our attribution of certain user locations for the first quarter of 2012. The first quarter of 2012 user metrics reflect a reclassification to more correctly attribute users by geographic region.

Revenue by User Geography

Revenue by user geography is geographically apportioned based on our estimation of the geographic location of our users when they perform a revenue-generating activity. This allocation differs from our revenue by geography disclosure in our consolidated financial statements where revenue is geographically apportioned based on the location of the advertiser or developer.

Payments Revenue Recognition Timing

Therefore starting in Q4, we expect to record all Payments revenues in the month the transaction occurs, net of estimated refunds or chargebacks. We anticipate that this change will result in a one-time increase in Payments revenue in the fourth quarter as we recognize revenue from an extra month of payments transactions (those occurring in September through December.)

In Q3 and prior, due to insufficient transaction history, Payments revenues have been recognized after the claim period lapses.

For example, transactions occurring in June are recognized as revenue 30 days later, in July, and included in Q3 revenue. So Q3 revenue reflects transactions that occurred during the months of June, July and August.

In Q4 we will have 24 months of historical

transactional information at which time we believe we will be able to reasonably estimate future refunds and chargebacks.

Q 3 2012 Q 4 2012 Q1 2013

June Jul Aug Sept Oct Nov Jan Mar Feb Dec

Payments terms and conditions provide for a 30-day claim period following a Payments transaction during which the customer may dispute the transaction.

Effective Tax Rate

Q2 and Q3 effective tax rates were influenced by significant share-based compensation expense resulting from our initial public offering, a portion of which is not tax-deductible. A combination of tax benefits recorded in Q2 and tax provisions in Q1 and Q3 result in an approximately 0% effective tax rate in the year-to-date period.

Limitations of Key Metrics

The numbers of our MAUs and DAUs and average revenue per user (ARPU) are calculated using internal

company data. While these numbers are based on what we believe to be reasonable estimates of our user

base for the applicable period of measurement, there are inherent challenges in measuring usage of our

products across large online and mobile populations around the world. For example, there may be

individuals who maintain one or more Facebook accounts in violation of our terms of service, despite our

efforts to detect and suppress such behavior. We estimate, for example, that “duplicate” accounts (an

account that a user maintains in addition to his or her principal account) may have represented

approximately 4.8% of our worldwide MAUs as of June 30, 2012. We also seek to identify “false” accounts,

which we divide into two categories: (1) user-misclassified accounts, where users have created personal

profiles for a business, organization, or non-human entity such as a pet (such entities are permitted on

Facebook using a Page rather than a personal profile under our terms of service); and (2) undesirable

accounts, which represent user profiles that we determine are intended to be used for purposes that violate

our terms of service, such as spamming. As of June 30, 2012, for example, we estimate user-misclassified

accounts may have represented approximately 2.4% of our worldwide MAUs and undesirable accounts

may have represented approximately 1.5% of our worldwide MAUs. We believe the percentage of

accounts that are duplicate or false is meaningfully lower in developed markets such as the United States

or Australia and higher in developing markets such as Indonesia and Turkey. However, these estimates

are based on an internal review of a limited sample of accounts and we apply significant judgment in

making this determination, such as identifying names that appear to be fake or other behavior that appears

inauthentic to the reviewers. As such, our estimation of duplicate or false accounts may not accurately

represent the actual number of such accounts. We are continually seeking to improve our ability to identify

duplicate or false accounts and estimate the total number of such accounts, and such estimates may be

affected by improvements or changes in our methodology.

22

Limitations of Key Metrics (continued)

Our metrics are also affected by applications on certain mobile devices that automatically contact our

servers for regular updates with no user action involved, and this activity can cause our system to count

the user associated with such a device as an active user on the day such contact occurs. For example, we

estimate that less than 5% of our estimated worldwide DAUs as of December 31, 2011 and 2010 resulted

from this type of automatic mobile activity, and that this type of activity had a substantially smaller effect on

our estimate of worldwide MAUs and mobile MAUs. The impact of this automatic activity on our metrics

varies by geography because mobile usage varies in different regions of the world. In addition, our data

regarding the geographic location of our users is estimated based on a number of factors, such as the

user’s IP address and self-disclosed location. These factors may not always accurately reflect the user’s

actual location. For example, a mobile-only user may appear to be accessing Facebook from the location

of the proxy server that the user connects to rather than from the user’s actual location. The

methodologies used to measure user metrics may also be susceptible to algorithm or other technical

errors. For example, in early June 2012, we discovered an error in the algorithm we use to estimate the

geographic location of our users that affected our attribution of certain user locations for the period ended

March 31, 2012. While this issue did not affect our overall worldwide MAU number, it did affect our

attribution of users to different geographic regions. We estimate that the number of MAUs as of March 31,

2012 for the United States and Canada region was overstated as a result of the error by approximately 3%

and these overstatements were offset by understatements in other regions. In addition, our estimates for

revenue by user location are also affected by these factors. We regularly review and may adjust our

processes for calculating these metrics to improve their accuracy. In addition, our MAU and DAU estimates

will differ from estimates published by third parties due to differences in methodology. For example, some

third parties are not able to accurately measure mobile users or do not count mobile users for certain user

groups or at all in their analyses.
