through income-based approaches utilizing market observable data.
Thus, the fair value of these assets is categorized as Level 2
within the fair value hierarchy.</p>

The warrants issued in January and August 2009 are
classified as liabilities. The fair value is determined using the
Black-Scholes-Merton option-pricing model, which requires the use
of significant judgment and estimates for the inputs in the model.
Accordingly, the fair value of these liabilities is categorized as
Level 3 within the fair value hierarchy. For additional information
related to the determination of fair value of warrants and a
reconciliation of changes in fair value, please read <i>Note 7,
Warrants</i> of the
unaudited condensed consolidated financial statements.</p>

The carrying amounts reported in the unaudited condensed

characteristics and comparable risk.</p>

The Company has periodically issued warrants in connection with
certain common stock offerings. The warrants issued in
January and August 2009 are classified as liabilities as
opposed to equity due to their settlement terms which require
settlement in registered shares. These warrants are non-cash
liabilities and the Company is not required to expend any cash to
settle these liabilities.</p>

The outstanding warrants classified as liabilities are recorded on
the unaudited condensed consolidated balance sheets and are
adjusted to fair value at each financial reporting period, with
changes in the fair value being recorded as “Gain (loss) on
change in warrant valuation” in the unaudited condensed
consolidated statements of operations and comprehensive loss. Fair
value is determined using the Black-Scholes-Merton option-pricing
model, which requires the use of significant judgment and estimates
for the inputs used in the model.</p>

In July 2010, the Company was awarded the Department of Defense
(“DoD”) contract managed by its Joint Project Manager
Medical Countermeasure Systems (“JPM-MCS”) program for
the advanced development of its hemorrhagic fever virus therapeutic
candidates, AVI-6002 and AVI-6003, against the Ebola and Marburg
viruses, respectively. In February 2012, the Company announced that
it received permission from the U.S. Food and Drug Administration
(“FDA”) to proceed with a single oligomer from
AVI-7288, one of the two components that make up AVI-6003, as the
lead product candidate against Marburg virus infection. In
August 2012, the Company received a stop-work order related to
the Ebola virus portion of the contract and, in October 2012, the
DoD terminated the Ebola portion of the contract for the
convenience of the government due to government funding
constraints.</p>

The remaining Marburg portion of the contract is structured into
four segments and has an aggregate remaining period of performance
spanning approximately four years if DoD exercises its options for
all segments. Activities under the first segment began in July
2010 and include preclinical studies and Phase I studies in healthy
volunteers. In February 2014, the Company announced positive safety
results from the Phase I multiple ascending dose study of
AVI-7288.</p>

After completion of the first segment, DoD has the option to
proceed to the next segment. If DoD exercises its options for
segments II, III and IV, the Company’s contract activities
would include all clinical and licensure activities necessary to
obtain FDA regulatory approval for the therapeutic candidate
against the Marburg virus. The funding for segments II, III and IV
of the Marburg virus portion of the contract is estimated to be
approximately $84.4 million.</p>

In August 2012, the Company was awarded a contract from the JPM-MCS
program. The contract was for approximately $3.9 million to
evaluate the feasibility of an intramuscular route of

treatment of Marburg virus. The period of performance for this
contract concluded in the third quarter of 2013. No revenue was

In November 2012, the Company entered into an agreement for a

years. During the three months ended March 31, 2014 and 2013,

<p style="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">
In July 2013, the Financial Accounting Standards Board
(“FASB”) issued new guidance which amends the guidance
related to the presentation of unrecognized tax benefits and allows
for the reduction of a deferred tax asset for a net operating loss
(“NOL”) carryforward whenever the NOL or tax credit
carryforward would be available to reduce the additional taxable
income or tax due if the tax position is disallowed. The new
guidance is effective for annual and interim periods for fiscal
years beginning after December 15, 2013, and early adoption is
permitted. Since the guidance relates only to the presentation of
unrecognized tax benefits, the adoption of this guidance did not
have a material effect on the Company’s financial position,
results of operations or cash flows.</p>

In November 2012, the Company notified 21 Bothell, Washington based
employees that they would be terminated as part of the corporate
headquarters relocation to Cambridge, Massachusetts. The employees
were given various incentives to remain through a transition period
which was completed in 2013. During the first quarter of 2014, the
transition period was extended to the end of the second quarter of
2014 for one employee. For the three months ended March 31, 2014,
the Company recorded a restructuring charge of less than $0.1
million to research and development expenses. For the three months
ended March 31, 2013, the Company recorded a restructuring charge
of $0.3 million to research and development expenses and $0.2
million to general and administrative expenses.</p>

Basic net loss per share is computed by dividing net loss by the
weighted-average number of shares of common stock outstanding.
Diluted net loss per share is computed by dividing net loss by the
weighted-average number of shares of common stock and dilutive
common stock equivalents outstanding. Given that the Company is in
a loss position for each of the periods presented, there is no
difference between basic and diluted net loss per share since the
effect of common stock equivalents would be anti-dilutive and are,
therefore, excluded from the diluted net loss per share
calculation.</p>

Sarepta Therapeutics, Inc. and its wholly-owned subsidiaries
(“Sarepta” or the “Company”) is a
biopharmaceutical company focused on the discovery and development
of unique RNA-based therapeutics for the treatment of rare and
infectious diseases. Applying its proprietary platform
technologies, the Company is able to target a broad range of
diseases and disorders through distinct RNA-based mechanisms of
action. The Company is focused on advancing the development of its
Duchenne muscular dystrophy (“DMD”) drug candidates,
including its lead product candidate, eteplirsen, for which the
Company is currently conducting an ongoing open label extension
study following completion of its initial Phase IIb clinical
trials. The Company is also focused on developing therapeutics for
the treatment of infectious diseases, including its lead infectious
disease program aimed at the development of a drug candidate for
the Marburg hemorrhagic fever virus for which the Company has
historically received significant financial support from U.S.
government research contracts.</p>
<p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt 'Times New Roman'; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px">
Since its inception in 1980, the Company has incurred losses of
approximately $571.5 million, substantially all of which resulted
from expenditures related to research and development and general
and administrative charges and loss on change in warrant valuation
partially offset by revenue generated from government research
contracts and other grants. The Company has not generated any
material revenue from product sales to date and there can be no
assurance that revenue from product sales will be achieved.
Moreover, even if the Company does achieve revenue from product
sales, it is likely to continue to incur operating losses in the
near term.</p>
<p style="MARGIN-BOTTOM: 0pt; WHITE-SPACE: normal; TEXT-TRANSFORM: none; WORD-SPACING: 0px; COLOR: rgb(0,0,0); FONT: 10pt 'Times New Roman'; MARGIN-TOP: 12pt; LETTER-SPACING: normal; TEXT-INDENT: 4%; -webkit-text-stroke-width: 0px">
As of March 31, 2014, the Company had $233.1 million of cash,
cash equivalents and investments, consisting of $49.1 million of
cash and cash equivalents, $176.1 million of short-term investments
and $7.9 million of restricted investments. On April 29, 2014,
the Company sold 2,650,000 shares of common stock in a public
offering at a price of $38.00 per share resulting in net proceeds
(after deducting underwriting discounts, commissions and other
estimated offering expenses) to the Company of approximately $94.5
million. The Company believes, taking into consideration
outstanding warrants and the net proceeds of $94.5 million from the
common stock offering, that its balance of cash, cash equivalents
and investments is sufficient to fund its current operational plan
for the next twelve months. Should the Company’s funding from
the U.S. government cease or be delayed, the Company would likely
curtail certain of its infectious disease research and development
efforts unless additional funding was obtained. The Company is also
likely to pursue additional cash resources through public or
private financings, seek additional government contracts and
establish collaborations with or license its technology to other
companies.</p>

The accompanying unaudited condensed consolidated financial

principles generally accepted in the United States of America
(“U.S. GAAP”), reflect the accounts of Sarepta

others. The information included in this quarterly report on Form

assets of $133.6 million primarily from U.S. federal and state NOL

intangibles. Due to uncertainties surrounding the Company’s
ability to generate future taxable income to realize these assets,
a full valuation allowance has been established to offset its net
deferred tax asset. Additionally, the Internal Revenue Code
rules could limit the future use of its NOL and research and
development credit carryforwards to offset future taxable income
based on ownership changes and the value of the Company’s

In July 2013, the Financial Accounting Standards Board
(“FASB”) issued new guidance which amends the guidance
related to the presentation of unrecognized tax benefits and allows
for the reduction of a deferred tax asset for a net operating loss
(“NOL”) carryforward whenever the NOL or tax credit
carryforward would be available to reduce the additional taxable
income or tax due if the tax position is disallowed. The new
guidance is effective for annual and interim periods for fiscal
years beginning after December 15, 2013, and early adoption is
permitted. Since the guidance relates only to the presentation of
unrecognized tax benefits, the adoption of this guidance did not
have a material effect on the Company’s financial position,
results of operations or cash flows.</p>

In June 2013, the Company entered into a lease agreement for its
headquarters located in Cambridge, Massachusetts. The agreement
calls for a security deposit in the form of a letter of credit
totaling $0.6 million. The Company purchased a certificate of
deposit (“CD”) to meet the requirement and it was
recorded as a long-term restricted investment in the unaudited
condensed consolidated balance sheets as of March 31, 2014. The
initial term of the lease agreement is for seven years with an
average annual base rent of approximately $2.4 million.</p>

In November 2013, the Company entered into the first amendment of
its lease agreement for its headquarters located in Cambridge,
Massachusetts. The amendment modified the original lease to add an
additional 15,077 square feet to its original space, increasing its
total rental space for its headquarters to 61,453 square feet. The
amendment calls for additional annual base rent of approximately
$0.5 million, subject to a 2.5% annual increase. In January 2014,
the Company entered into a sublease for the 15,077 square feet of
office space with an unrelated third party for an 18-month term
with a total base rent of approximately $0.7 million.</p>

The Company also leases laboratory and office space in Corvallis,
Oregon. The annual base rent at the Corvallis, Oregon facility is
approximately $0.9 million, excluding other occupancy costs, and is
subject to an annual increase of 3%.</p>

The Company has license agreements for which it is obligated to pay
minimum royalties if the Company does not terminate the relevant
agreement. The notice period to terminate these agreements is six
months or less. Royalty payments under these agreements were less
than $0.1 million for the three months ended March 31, 2014

The Company is also obligated to pay royalties upon the net sales

2007, the Company is obligated to pay a mid single-digit percentage
royalty on the net sales of any product developed pursuant to the
agreement with Charley’s Fund up to a maximum of $3.4
million. In May 2003, the Company entered into a collaboration and
license agreement with Isis-Ercole. The range of percentage of
royalty payments under this agreement, should such payments ever be
made, is from a fraction of a percent to mid-single-digit
percentages.</p>

In the normal course of business, the Company may from time to time
be named as a party to various legal claims, actions and
complaints, including matters involving securities, employment,
intellectual property, effects from the use of therapeutics
utilizing its technology, or others. For example, in January 2014,
a former consultant of the Company filed a complaint alleging
breach of contract, among other claims, and seeking approximately
$4 million in damages, plus certain additional fees and costs, from
the Company. In addition, purported class action complaints were
filed against the Company and certain of its officers in the U.S.
District Court for the District of Massachusetts on
January 27, 2014 (Corban v. Sarepta et al) and
January 29, 2014 (Baradanian v. Sarepta et al). The plaintiffs
are alleged purchasers of Company common stock who seek to bring
claims on behalf of themselves and persons or entities that
purchased or acquired securities of the Company between
July 24, 2013 and November 12, 2013. The complaints
allege that the defendants violated the federal securities laws in
connection with disclosures related to eteplirsen, the
Company’s lead therapeutic candidate for DMD, and seek
damages in an unspecified amount. Given the relatively early stages
of the proceedings in the above mentioned purported claims, at this
time, no assessment can be made as to the likely outcome of these
claims or whether the outcomes would have a material impact on the
Company.</p>

In February 2013, the Company issued two letters of credit totaling
$7.3 million to a contract manufacturing vendor in connection with
certain manufacturing agreements. The obligations secured by the
letters of credit are fulfilled upon payment for certain minimum
volume commitments and construction milestones. To meet the
requirement of the letters of credit, the Company purchased $7.3
million in CDs with May 2014 maturity dates. If the minimum volume
commitments and construction milestones have not occurred at that
time, the letters of credit will be extended. The $7.3 million was
recorded as restricted investments in the unaudited condensed
consolidated balance sheets as of March 31, 2014.</p>

The Company’s accounts receivable primarily arise from
government research contracts and other grants. They are generally
stated at invoiced amount and do not bear interest. Because the
accounts receivable are primarily from government agencies and
historically no amounts have been written off, an allowance for
doubtful accounts receivable is not considered necessary. The
accounts receivable balance included unbilled receivables of $5.5
million and $2.4 million at March 31, 2014 and
December 31, 2013, respectively. Approximately $3.8 million of
the unbilled receivables as of March 31, 2014 are subject to a U.S.

The risk-free interest rate is estimated using an average of U.S. Treasury bill interest rates that correlate to the prevailing interest rates at the valuation date.
The expected dividend yield is zero as the Company has not paid any dividends to date and does not expect to pay dividends prior to the expiration of the warrants.
The expected lives are based on the remaining contractual lives of the related warrants at the valuation date.
The expected volatility is estimated using a blend of calculated volatility of the Company's common stock over a historical period and implied volatility in exchange-traded options associated with the Company's common stock.
Warrants, stock options, restricted stock awards, restricted stock units and stock appreciation rights to purchase approximately 6,096,000 and 5,997,000 shares of common stock were excluded from the net loss per share calculation for the three months ended March 31, 2014 and 2013, respectively, as their effect would have been anti-dilutive.
