SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains forward-looking statements that involve risks, uncertainties, and assumptions. Forward-looking statements are all statements, other than statements of historical facts, that discuss our current expectation and projections relating to our strategy, future operations, future financial position, future revenues, projected costs, prospects, plans, and objectives of management. These statements may be preceded by, followed by or include the words "aim," "anticipate," "believe," "can," "could," "estimate," "expect," "forecast," "intend," "likely," "may," "outlook," "plan," "potential," "predict," "project," "seek," "should," "will," "would," the negatives or plurals thereof, and other words and terms of similar meaning, although not all forward-looking statements contain these identifying words.

We have based these forward-looking statements on our current expectations and projections about future events. Although we believe that our assumptions made in connection with the forward-looking statements are reasonable, we cannot assure you that the assumptions and expectations will prove to be correct. You should understand that the following important factors could affect our future results and could cause those results or other outcomes to differ materially from those expressed or implied in our forward-looking statements:

•the scope, progress, results and costs of our clinical trials of our drug candidates;

•the cost of manufacturing drug supply for our commercial, clinical and preclinical studies, including the cost of manufacturing Pompe Enzyme Replacement Therapy ("ERT" or "ATB200" or "cipaglucosidase alfa");

•the future results of preclinical research and subsequent clinical trials for pipeline candidates we may identify from time to time, including our ability to obtain regulatory approvals and commercialize these therapies and obtain market acceptance for such therapies;

•the costs, timing, and outcome of regulatory review of our product candidates, including AT-GAA;

•any changes in regulatory standards relating to the review of our product candidates, including AT-GAA;

•the number and development requirements of other product candidates that we pursue;

•the costs of commercialization activities, including product marketing, sales, and distribution;

•the emergence of competing technologies and other adverse market developments;

•our ability to successfully commercialize Galafold® (also referred to as "migalastat HCl") and, if our regulatory applications are approved, AT-GAA;

•our ability to manufacture or supply sufficient clinical or commercial products, including Galafold® and AT-GAA;

•our ability to obtain reimbursement for Galafold® and, if our regulatory applications are approved, AT-GAA;

•our ability to satisfy post-marketing commitments or requirements for continued regulatory approval of Galafold®, and, if approved and applicable, AT-GAA;

•our ability to obtain market acceptance of Galafold® and, if our regulatory applications are approved, AT-GAA;

•the costs of preparing, filing, and prosecuting patent applications and maintaining, enforcing, and defending intellectual property-related claims, including Hatch-Waxman litigation;

•the impact of litigation that has been or may be brought against us or of litigation that we are pursuing or may pursue against others;

•the extent to which we acquire or invest in businesses, products, and technologies;

•our ability to successfully integrate our acquired products and technologies into our business, or successfully divest or license existing products and technologies from our business, including the possibility that the expected benefits of the transactions will not be fully realized by us or may take longer to realize than expected;

•our ability to establish licensing agreements, collaborations, partnerships or other similar arrangements and to obtain milestone, royalty, or other payments from any such collaborators;

•the extent to which our business could be adversely impacted by the effects of the novel coronavirus ("COVID-19") outbreak, including due to actions by us, governments, our customers, our suppliers, or other third parties to control the spread of COVID-19, or by other health epidemics or pandemics;

•the costs associated with, and our ability to comply with, emerging environmental, social and governance standards;

•our ability to accurately forecast revenue, operating expenditures, or other metrics impacting profitability;

•fluctuations in foreign currency exchange rates; and

•changes in accounting standards.

In light of these risks and uncertainties, we may not actually achieve the plans, intentions or expectations disclosed in our forward-looking statements, and you should not place undue reliance on our forward-looking statements. Actual results or events could differ materially from the plans, intentions, and expectations disclosed in the forward-looking statements we make. We have included important factors in the cautionary statements included in Part I Item 1A — Risk Factors of the Annual Report on Form 10-K for the fiscal year ended December 31, 2021, that we believe could cause actual results or events to differ materially from the forward-looking statements that we make. Those factors and the other risk factors described herein are not necessarily all of the important factors that could cause actual results or developments to differ materially from those expressed in any of our forward-looking statements. Other unknown or unpredictable factors also could harm our results. Our forward-looking statements do not reflect the potential impact of any future collaborations, alliances, business combinations, partnerships, strategic out-licensing of certain assets, the acquisition of preclinical-stage, clinical-stage, marketed products or platform technologies or other investments we may make. Consequently, there can be no assurance that actual results or developments anticipated by us will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, us. Given these uncertainties, investors are cautioned not to place undue reliance on such forward-looking statements.

You should read this Quarterly Report on Form 10-Q in conjunction with our Annual Report on Form 10-K for the fiscal year ended December 31, 2021 (including the documents incorporated by reference therein) completely and with the understanding that our actual future results may be materially different from what we expect. These forward-looking statements speak only as of the date of this report. We undertake no obligation, and specifically decline any obligation, to publicly update or revise any forward-looking statements, even if experience or future developments make it clear that projected results expressed or implied in such statements will not be realized, except as may be required by law.

1. Description of Business

Amicus Therapeutics, Inc. (the "Company") is a global, patient-dedicated biotechnology company focused on discovering, developing, and delivering novel medicines for rare diseases. The Company has a portfolio of product opportunities including the first, oral monotherapy for Fabry disease that has achieved widespread global approval and a differentiated biologic for Pompe disease, that is under review with the U.S. Food and Drug Administration ("FDA") as well as the European Medicines Agency ("EMA"). The Company is committed to discovering and developing next generation therapies in Fabry and Pompe diseases.

The cornerstone of the Company's portfolio is Galafold® (also referred to as "migalastat"), the first and only approved oral precision medicine for people living with Fabry disease who have amenable genetic variants. Migalastat is currently approved under the trade name Galafold® in the United States ("U.S."), European Union ("E.U."), United Kingdom ("U.K."), and Japan, with multiple additional approvals granted and applications pending in several geographies around the world.

The lead biologics program of the Company's pipeline is Amicus Therapeutics GAA ("AT-GAA", also known as ATB200/AT2221, or cipaglucosidase alfa/miglustat), a novel, two-component, potential best-in-class treatment for Pompe disease. In February 2019, the FDA granted Breakthrough Therapy designation ("BTD") to AT-GAA for the treatment of late onset Pompe disease. In September 2021, the FDA set the Prescription Drug User Fee Act ("PDUFA") target action date of May 29, 2022 for the New Drug Application ("NDA") for miglustat and July 29, 2022 for the Biologics License Application ("BLA") for cipaglucosidase alfa. The EMA validated the Marketing Authorization Application (“MAA”) in the fourth quarter of 2021. On May 9, 2022, the FDA extended the review period for the NDA for miglustat and the BLA for cipaglucosidase alfa resulting in revised PDUFA action dates of August 29, 2022 and October 29, 2022, respectively.

The Company's operations have not been significantly impacted by the novel coronavirus (“COVID-19”) pandemic to date. The Company continued to observe increased lag time between patient identification and Galafold® initiation due to the continued prevalence of COVID-19 and its ongoing impact on access to treatment for people living with Fabry disease in certain markets. The Company has maintained operations in all geographies, secured its global supply chain for its commercial and clinical products, as well as maintained the operational integrity of its clinical trials, with minimal disruptions. Whether the Company will continue to operate without any significant disruptions will depend on the continued health of its employees, the ongoing demand for Galafold® and the continued operation of its global supply chain. The Company has continued to provide uninterrupted access to medicines for those in need of treatment, while prioritizing the health and safety of its global workforce. However, the Company's results of operations in future periods may be negatively impacted by unknown future impacts from the COVID-19 pandemic.

The Company had an accumulated deficit of $2.4 billion as of June 30, 2022 and anticipates incurring losses through the fiscal year ending December 31, 2022 and beyond. The Company has historically funded its operations through stock offerings, Galafold® revenues, debt issuances, collaborations, and other financing arrangements.

Based on its current operating model, the Company believes that the current cash position, which includes expected revenues, is sufficient to fund the Company's operations and ongoing research programs to achieve self-sustainability. Potential impacts of the COVID-19 pandemic, business development collaborations, pipeline expansion, and investment in manufacturing capabilities could impact the Company's future capital requirements.

2. Summary of Significant Accounting Policies

Basis of Presentation

The Company has prepared the accompanying unaudited Consolidated Financial Statements in accordance with the U.S. generally accepted accounting principles ("U.S. GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10-01 of Regulation S-X. Accordingly, they do not include all of the information and disclosures required by U.S. GAAP for complete financial statements. In the opinion of management, the accompanying unaudited Consolidated Financial Statements reflect all adjustments, which include only normal recurring adjustments, necessary to present fairly the Company's interim financial information.

The accompanying unaudited Consolidated Financial Statements and related notes should be read in conjunction with the Company's financial statements and related notes as contained in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2021. For a complete description of the Company's accounting policies, please refer to the Annual Report on Form 10-K for the fiscal year ended December 31, 2021.

Consolidation

The Consolidated Financial Statements include the accounts of the Company and its subsidiaries. Intercompany accounts and transactions are eliminated in consolidation.

Foreign Currency Transactions

The functional currency for most of the Company's foreign subsidiaries is their local currency. For non-U.S. subsidiaries that transact in a functional currency other than the U.S. dollar, assets and liabilities are translated at current rates of exchange at the balance sheet date. Income and expense items are translated at the average foreign exchange rates for the period. Adjustments resulting from the translation of the financial statements of the Company's foreign operations into U.S. dollars are excluded from the determination of net income and are recorded in accumulated other comprehensive income, a separate component of stockholders' equity.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

Additionally, the Company assessed the impact COVID-19 pandemic has had on its operations and financial results as of June 30, 2022 and through the issuance of these financial statements. The Company’s analysis was informed by the facts and circumstances as they were known to the Company. This assessment considered the impact COVID-19 may have on financial estimates and assumptions that affect the reported amounts of assets and liabilities and revenue and expenses.

Cash, Cash Equivalents, Marketable Securities, and Restricted Cash

The Company considers all highly liquid investments purchased with a maturity of three months or less at the date of acquisition to be cash equivalents. Marketable securities consist of fixed income investments with a maturity of greater than three months and other highly liquid investments that can be readily purchased or sold using established markets. These investments are classified as available-for-sale and are reported at fair value on the Company's Consolidated Balance Sheets. Unrealized holding gains and losses are reported within other comprehensive loss in the Company's Consolidated Statements of Comprehensive Loss. Fair value is based on available market information including quoted market prices, broker or dealer quotations, or other observable inputs.

Restricted cash consists primarily of funds held to satisfy the requirements of certain agreements that are restricted in their use and is included in other current assets and other non-current assets on the Company's Consolidated Balance Sheets.

Concentration of Credit Risk

The Company's financial instruments that are exposed to concentration of credit risk consist primarily of cash, cash equivalents, and marketable securities. The Company maintains its cash and cash equivalents in bank accounts, which, at times, exceed federally insured limits. The Company invests its marketable securities in high-quality commercial financial instruments. The Company has not recognized any losses from credit risks on such accounts during any of the periods presented. The Company believes it is not exposed to significant credit risk on its cash, cash equivalents, or marketable securities.

The Company is subject to credit risk from its accounts receivable related to its product sales of Galafold®. The Company's accounts receivable at June 30, 2022 have arisen from product sales primarily in Europe and the U.S. The Company will periodically assess the financial strength of its customers to establish allowances for anticipated losses, if any. For accounts receivable that have arisen from named patient sales, the payment terms are predetermined, and the Company evaluates the creditworthiness of each customer on a regular basis. As of June 30, 2022, the Company recorded an allowance for doubtful accounts of $0.1 million.

Property and Equipment

Property and equipment are stated at cost, less accumulated depreciation. Depreciation is calculated over the estimated useful lives of the respective assets, which range from three to five years, or the lesser of the related initial term of the lease or useful life for leasehold improvements.

The initial cost of property and equipment consists of its purchase price and any directly attributable costs of bringing the asset to its working condition and location for its intended use. Expenditures incurred after the fixed assets have been put into operation, such as repairs and maintenance, are charged to income in the period in which the costs are incurred. Major replacements, improvements, and additions are capitalized in accordance with Company policy.

The Company evaluates long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable. If indications of impairment exist, projected future undiscounted cash flows associated with the asset or asset group are compared to the carrying value of the asset to determine whether the asset or asset group's value is recoverable. If impairment is determined, the Company writes down the asset to its estimated fair value and records an impairment loss equal to the excess of the carrying value of the long-lived asset over its estimated fair value in the period at which such a determination is made.

During the six months ended June 30, 2022, in connection with the strategic prioritization of its gene therapy portfolio, the Company performed an assessment of its fixed assets. As a result, the Company recognized an impairment charge of $6.6 million.

Revenue Recognition

The Company's net product sales consist of sales of Galafold® for the treatment of Fabry disease. The Company has recorded revenue on sales where Galafold® is available either on a commercial basis or through a reimbursed early access program. Orders for Galafold® are generally received from distributors and pharmacies, with the ultimate payor often a government authority.

The Company recognizes revenue when its performance obligations to its customers have been satisfied, which occurs at a point in time when the pharmacies or distributors obtain control of Galafold®. The transaction price is determined based on fixed consideration in the Company's customer contracts and is recorded net of estimates for variable consideration, which are third party discounts and rebates. The identified variable consideration is recorded as a reduction of revenue at the time revenue from the sale of Galafold® is recognized. The Company recognizes revenue to the extent that it is probable that a significant revenue reversal will not occur in a future period. These estimates may differ from actual consideration received. The Company evaluates these estimates each reporting period to reflect known changes.

The following table summarizes the Company's net product sales from Galafold® disaggregated by geographic area:


	Three Months Ended June 30,				Six Months Ended June 30,
(in thousands)	2022		2021		2022		2021
U.S.	$	27,540	$	23,678	$	51,718	$	44,531
Ex-U.S.	53,191		53,735		107,728		99,284
Total net product sales	$	80,731	$	77,413	$	159,446	$	143,815

Inventories and Cost of Goods Sold

Inventories are stated at the lower of cost and net realizable value, determined by the first-in, first-out method. Inventories are reviewed periodically to identify slow-moving or obsolete inventory based on projected sales activity as well as product shelf-life. In evaluating the recoverability of inventories produced, the probability that revenue will be obtained from the future sale of the related inventory is considered and inventory value is written down for inventory quantities in excess of expected requirements. Expired inventory is disposed of and the related costs are recognized as cost of goods sold in the Consolidated Statements of Operations.

Cost of goods sold includes the cost of inventory sold, manufacturing and supply chain costs, product shipping and handling costs, provisions for excess and obsolete inventory, as well as royalties payable.

Research and Development Costs

Research and development costs are expensed as incurred. Research and development expense consist primarily of costs related to personnel, including salaries and other personnel related expenses, consulting fees, and the cost of facilities and support services used in drug development. Assets acquired that are used for research and development and have no future alternative use are expensed as in-process research and development.

In the second quarter of 2022, as part of the Company’s strategic prioritization of its gene therapy portfolio, the Company recorded a non-recurring $20.0 million liability associated with the expense of contractual obligations from which the Company will no longer receive further economic benefit. A liability for costs that will continue to be incurred under a contract for its remaining term without economic benefit to the entity is recognized at the cease-use date. This liability is presented as a component of accrued expenses and other current liabilities within the Company's Consolidated Balance Sheets.

Recent Accounting Developments

The Company has evaluated recent accounting pronouncements and believes that none of them will have a material effect on the Company's Consolidated Financial Statements or related disclosures.

3. Cash, Cash Equivalents, Marketable Securities, and Restricted Cash

As of June 30, 2022, the Company held $235.6 million in cash and cash equivalents and $151.2 million of marketable securities which are reported at fair value on the Company's Consolidated Balance Sheets. Unrealized holding gains and losses are generally reported within other comprehensive loss in the Company's Consolidated Statements of Comprehensive Loss. If a decline in the fair value of a marketable security below the Company's cost basis is determined to be other-than-temporary or if an available-for-sale debt security’s fair value is determined to be less than the amortized cost and the Company intends or is more than likely to sell the security before recovery and it is not considered a credit loss, such security is written down to its estimated fair value as a new cost basis and the amount of the write-down is included in earnings as an impairment charge. If the unrealized loss of an available-for-sale debt security is determined to be a result of credit loss, the Company would recognize an allowance and the corresponding credit loss would be included in earnings.

The Company regularly invests excess operating cash in deposits with major financial institutions, money market funds, notes issued by the U.S. government, as well as fixed income investments and U.S. bond funds, both of which can be readily purchased and sold using established markets. The Company believes that the market risk arising from its holdings of these financial instruments is mitigated as many of these securities are either government backed or of the highest credit rating. Investments that have original maturities greater than three months but less than one year are classified as current.

Cash, cash equivalents and marketable securities are classified as current unless mentioned otherwise below and consisted of the following:


	As of June 30, 2022

Total cash, cash equivalents, and marketable securities	$	482,568	$	7	$	(79)	$	482,496

For both the six months ended June 30, 2022 and the fiscal year ended December 31, 2021, there were no realized gains or losses. The cost of securities sold is based on the specific identification method.

Unrealized loss positions in the marketable securities as of June 30, 2022 and December 31, 2021 reflect temporary impairments and are not a result of credit loss. Additionally, as these positions have been in a loss position for less than twelve months and the Company does not intend to sell these securities before recovery, the losses are recognized in other comprehensive (loss) gain. The fair value of these marketable securities in unrealized loss positions was $140.5 million and $173.4 million as of June 30, 2022 and December 31, 2021, respectively.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the Consolidated Balance Sheets that sum to the total of the same such amounts shown in the Consolidated Statements of Cash Flows.

6. Share-Based Compensation

The Company's Amended and Restated 2007 Equity Incentive Plan (the "Plan") provides for the granting of restricted stock units and options to purchase common stock in the Company to employees, directors, advisors, and consultants at a price to be determined by the Company's Board of Directors. The Plan is intended to encourage ownership of stock by employees and consultants of the Company and to provide additional incentives for them to promote the success of the Company's business. The Board of Directors, or its committee, is responsible for determining the individuals to be granted options, the number of options each individual will receive, the option price per share, and the exercise period of each option.

Stock Option Grants

The fair value of the stock options granted is estimated on the date of grant using a Black-Scholes option pricing model with the following weighted-average assumptions:


	Three Months Ended June 30,						Six Months Ended June 30,
	2022			2021			2022			2021
Expected stock price volatility	61.3		%	65.5		%	62.2		%	66.4		%
Risk free interest rate	3.0		%	0.7		%	1.6		%	0.5		%
Expected life of options (years)	5.3			5.4			5.3			5.4
Expected annual dividend per share	$	—		$	—		$	—		$	—

A summary of the Company's stock options for the six months ended June 30, 2022 were as follows:


	Number of Shares	Weighted Average Exercise Price		Weighted Average Remaining Years	Aggregate Intrinsic Value
	(in thousands)				(in millions)
Options outstanding, December 31, 2021	14,731	$	11.08
Granted	5,402	$	11.55
Exercised	(339)	$	5.60
Forfeited	(333)	$	12.36
Expired	(178)	$	11.98
Options outstanding, June 30, 2022	19,283	$	11.28	7.0	$	22.2
Vested and unvested expected to vest, June 30, 2022	17,589	$	11.18	6.8	$	21.5
Exercisable at June 30, 2022	10,377	$	10.38	5.2	$	18.3

As of June 30, 2022, the total unrecognized compensation cost related to non-vested stock options granted was $39.5 million and is expected to be recognized over a weighted average period of three years.

Restricted Stock Units and Performance-Based Restricted Stock Units (collectively "RSUs")

RSUs awarded under the Plan are generally subject to graded vesting and are contingent on an employee's continued service. RSUs are generally subject to forfeiture if employment terminates prior to the release of vesting restrictions. The Company expenses the cost of the RSUs, which is determined to be the fair market value of the shares of common stock underlying the RSUs at the date of grant, ratably over the period during which the vesting restrictions lapse. A summary of non-vested RSU activity under the Plan for the six months ended June 30, 2022 is as follows:


	Number of Shares	Weighted Average Grant Date Fair Value		Weighted Average Remaining Years	Aggregate Intrinsic Value
	(in thousands)				(in millions)
Non-vested units as of December 31, 2021	7,341	$	13.90
Granted	4,815	$	11.97
Vested	(1,738)	$	12.40
Forfeited	(252)	$	12.10
Non-vested units as of June 30, 2022	10,166	$	13.13	2.4	$	109.2

All non-vested units are expected to vest over their normal term. As of June 30, 2022, there was $65.8 million of total unrecognized compensation cost related to unvested RSUs with service-based vesting conditions. These costs are expected to be recognized over a weighted average period of two years.

Compensation Expense Related to Equity Awards

The following table summarizes information related to compensation expense recognized in the Consolidated Statements of Operations related to the equity awards:


	Three Months Ended June 30,				Six Months Ended June 30,
(in thousands)	2022		2021		2022		2021
Research and development expense	$	4,379	$	3,152	$	13,744	$	9,457
Selling, general, and administrative expense	8,084		8,584		29,370		22,633
Total equity compensation expense	$	12,463	$	11,736	$	43,114	$	32,090

7. Assets and Liabilities Measured at Fair Value

The Company's financial assets and liabilities are measured at fair value and classified within the fair value hierarchy, which is defined as follows:

Level 1 — Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2 — Inputs other than quoted prices in active markets that are observable for the asset or liability, either directly or indirectly.

Level 3 — Inputs that are unobservable for the asset or liability.

A summary of the fair value of the Company's recurring assets and liabilities aggregated by the level in the fair value hierarchy within which those measurements fall as of June 30, 2022 are identified in the following tables:


(in thousands)	Level 2		Total
Assets:
Commercial paper	$	102,846	$	102,846
U.S. government agency bonds	44,964		44,964
Asset-backed securities	2,991		2,991
Money market	5,362		5,362
	$	156,163	$	156,163


(in thousands)	Level 2		Level 3		Total
Liabilities:
Contingent consideration payable	$	—	$	19,266	$	19,266
Deferred compensation plan liability	4,977		—		4,977
	$	4,977	$	19,266	$	24,243

A summary of the fair value of the Company's recurring assets and liabilities aggregated by the level in the fair value hierarchy within which those measurements fall as of December 31, 2021 are identified in the following tables:


(in thousands)	Level 2		Total
Assets:
Commercial paper	$	174,531	$	174,531
Corporate debt securities	32,311		32,311
Asset-backed securities	30,056		30,056
Money market	5,150		5,150
	$	242,048	$	242,048


(in thousands)	Level 2		Level 3		Total
Liabilities:
Contingent consideration payable	$	—	$	20,339	$	20,339
Deferred compensation plan liability	4,800		—		4,800
	$	4,800	$	20,339	$	25,139

The Company's Senior Secured Term Loan due 2026 falls into the Level 2 category within the fair value level hierarchy and the fair value was determined using quoted prices for similar liabilities in active markets, as well as inputs that are observable for the liability (other than quoted prices), such as interest rates that are observable at commonly quoted intervals. The carrying value of the Senior Secured Term Loan due 2026 approximates the fair value.

The Company did not have any Level 3 assets as of June 30, 2022 or December 31, 2021.

Cash, Money Market Funds, and Marketable Securities

The Company classifies its cash within the fair value hierarchy as Level 1 as these assets are valued using quoted prices in an active market for identical assets at the measurement date. The Company considers its investments in marketable securities as available-for-sale and classifies these assets and the money market funds within the fair value hierarchy as Level 2 primarily utilizing broker quotes in a non-active market for valuation of these securities.

Contingent Consideration Payable

The contingent consideration payable resulted from the acquisition of Callidus Biopharma, Inc. ("Callidus") in November 2013. The most recent valuation was determined using a probability weighted discounted cash flow valuation approach. Gains and losses are included in the Consolidated Statements of Operations.

The contingent consideration payable for Callidus has been classified as a Level 3 recurring liability as its valuation requires substantial judgment and estimation of factors that are not currently observable in the market. If different assumptions

were used for the various inputs to the valuation approach, the estimated fair value could be significantly higher or lower than the fair value the Company determined.

The following significant unobservable inputs were used in the valuation of the contingent consideration payable of Callidus for the ATB200 Pompe disease program:

Contingent Consideration

Liability

Fair Value as of June 30, 2022

Clinical and regulatory milestones

19,266

Probability weighted discounted cash flow

Probability of achievement of milestones

75% - 88%

Projected year of payments

2022 - 2023

Contingent consideration liabilities are remeasured to fair value each reporting period using discount rates, probabilities of payment, and projected payment dates. Projected contingent payment amounts related to clinical and regulatory based milestones are discounted back to the current period using a discounted cash flow model. Increases in discount rates and the time to payment may result in lower fair value measurements. Increases or decreases in any of those inputs together, or in isolation, may result in a significantly lower or higher fair value measurement. There is no assurance that any of the conditions for the milestone payments will be met.

The following table shows the change in the balance of contingent consideration payable for the three and six months ended June 30, 2022 and 2021, respectively:


	Three Months Ended June 30,				Six Months Ended June 30,
(in thousands)	2022		2021		2022		2021
Balance, beginning of the period	$	19,151	$	26,296	$	20,339	$	25,825
Changes in fair value during the period, included in the Consolidated Statements of Operations	115		1,021		(1,073)		1,492
Balance, end of the period (1)	$	19,266	$	27,317	$	19,266	$	27,317

______________________________

(1) As certain milestones are expected to be reached within the next twelve months, the June 30, 2022 balance was recorded as a current liability in the Consolidated Balance Sheets.

8. Basic and Diluted Net Loss per Common Share

The following table provides a reconciliation of the numerator and denominator used in computing basic and diluted net loss attributable to common stockholders per common share:


	Three Months Ended June 30,				Six Months Ended June 30,
(in thousands, except per share amounts)	2022		2021		2022		2021
Numerator:
Net loss attributable to common stockholders	$	(62,157)	$	(51,225)	$	(147,417)	$	(116,889)
Denominator:
Weighted average common shares outstanding — basic and diluted	291,970,562		266,398,516		288,646,587		265,384,865

Dilutive common stock equivalents would include the dilutive effect of common stock options, convertible debt units, RSUs, and warrants for common stock equivalents. Potentially dilutive common stock equivalents were excluded from the diluted earnings per share denominator for all periods because of their anti-dilutive effect. Weighted average common shares outstanding includes outstanding pre-funded warrants with an exercise price of $0.01.

The table below presents potential shares of common stock that were excluded from the computation as they were anti-dilutive using the treasury stock method:


	As of June 30,
(in thousands)	2022	2021
Options to purchase common stock	19,283	14,962
Unvested restricted stock units	10,166	7,412
Convertible notes	—	458
Total number of potentially issuable shares	29,449	22,832

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion should be read in conjunction with the unaudited Consolidated Financial Statements and the notes thereto included in this Quarterly Report on Form 10-Q and the audited Consolidated Financial Statements and the notes thereto included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021. Some of the statements we make in this section are forward-looking statements within the meaning of the federal securities laws. For a complete discussion of forward-looking statements, see the section in this Quarterly Report on Form 10-Q entitled “Special Note Regarding Forward-Looking Statements”. Certain risk factors may cause actual results, performance or achievements to differ materially from those expressed or implied by the following discussion. For a discussion of such risk factors, see the section in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021 entitled “Risk Factors”.

Overview

We are a global, patient-dedicated biotechnology company focused on discovering, developing, and delivering novel medicines for rare diseases. We have a portfolio of product opportunities including the first, oral monotherapy for Fabry disease that has achieved widespread global approval and a differentiated biologic for Pompe disease that is under review with the U.S. Food and Drug Administration ("FDA") as well as the European Medicines Agency ("EMA"). We are committed to discovering and developing next generation therapies in Fabry and Pompe diseases.

The cornerstone of our portfolio is Galafold® (also referred to as "migalastat"), the first and only approved oral precision medicine for people living with Fabry disease who have amenable genetic variants. Migalastat is currently approved under the trade name Galafold® in the United States ("U.S."), European Union ("E.U."), United Kingdom ("U.K."), and Japan, with multiple additional approvals granted and applications pending in several geographies around the world.

The lead biologics program of our pipeline is Amicus Therapeutics GAA ("AT-GAA", also known as ATB200/AT2221, or cipaglucosidase alfa/miglustat), a novel, two-component, potential best-in-class treatment for Pompe disease. In February 2019, the FDA granted Breakthrough Therapy designation ("BTD") to AT-GAA for the treatment of late onset Pompe disease. In September 2021, the FDA set the Prescription Drug User Fee Act ("PDUFA") target action date of May 29, 2022 for the New Drug Application ("NDA") for miglustat and July 29, 2022 for the Biologics License Application ("BLA") for cipaglucosidase alfa. The EMA validated the Marketing Authorization Application (“MAA”) in the fourth quarter of 2021. On May 9, 2022, the FDA extended the review period for the NDA for miglustat and the BLA for cipaglucosidase alfa resulting in revised PDUFA action dates of August 29, 2022 and October 29, 2022, respectively.

Our Strategy

Our strategy is to create, manufacture, test, and deliver the highest quality medicines for people living with rare diseases through internally developed, jointly developed, acquired, or in-licensed products and product candidates that have the potential to obsolete current treatments, provide significant benefits to patients, and be first- or best-in-class. We are leveraging our global capabilities to develop and broaden our lead franchises in Fabry and Pompe disease, with focused discovery work on next generation therapies and novel platform technologies.

Our operations have not been significantly impacted by the novel coronavirus (“COVID-19”) pandemic thus far. The Company continued to observe increased lag time between patient identification and Galafold® initiation due to the continued prevalence of COVID-19 and its ongoing impact on access to treatment for people living with Fabry disease in certain markets. We have maintained operations in all geographies, secured our global supply chain for our commercial and clinical products, as well as maintained the operational integrity of our clinical trials, with minimum disruptions. Our ability to continue to operate without any significant disruptions will depend on the continued health of our employees, the ongoing demand for Galafold® and the continued operation of our global supply chain. We have continued to provide uninterrupted access to medicines for those in need of treatment, while prioritizing the health and safety of our global workforce. However, our results of operations in future periods may be negatively impacted by unknown future impacts from the COVID-19 pandemic.

Highlights of our progress include:

•Commercial and regulatory success in Fabry disease. For the six months ended June 30, 2022, Galafold® revenue totaled $159.4 million, an increase of $15.6 million compared to the same period in the prior year. We continue to see strong commercial momentum and expansion into additional geographies. In countries where we have been operating the longest, we see an increasing proportion of previously untreated patients come onto Galafold®. In the U.S., we

continue to see a significant increase in patients from a growing and very wide prescriber base. Across all markets, we see a high rate of compliance and adherence to this oral treatment option.

•Pompe disease clinical program milestones. In February 2021, we reported topline results from the Phase 3 study of AT-GAA (ATB200-03, also known as "PROPEL"). In June 2021, the MHRA granted AT-GAA a positive scientific opinion through the Early Access to Medicines Scheme ("EAMS") which permits eligible adults living with late-onset Pompe disease ("LOPD") who have received alglucosidase alfa for at least 2 years to switch to AT-GAA prior to marketing authorization in the U.K. We completed the submission of the rolling BLA and NDA to the FDA, which was accepted for review in September 2021, and in the fourth quarter of 2021, the MAA was submitted and validated by the EMA. In March 2022, we announced positive long-term data from our ongoing phase 1/2 clinical study. Study participants treated with AT-GAA for up to 36 months demonstrated persistent and durable effects on six-minute walk test distance and measures of motor function and muscle strength, stability, or increase in forced vital capacity, and reductions in biomarkers of muscle damage and disease substrate. In June 2022, the French National Agency for the Medicines and Health Products Safety granted the first reimbursed access to AT-GAA under their compassionate access program.

•Pipeline advancement and growth. We are leveraging our global capabilities to develop and broaden our lead franchises in Fabry and Pompe disease, with focused discovery work on next generation therapies and novel platform technologies.

•Manufacturing. We have managed our clinical and commercial supply chains during the COVID-19 pandemic such that as of the date hereof we have not experienced supply impacts. We have been able to continue to meet required commercial demand for Galafold® as well as supply our ongoing Pompe disease clinical studies and access programs including EAMS without interruption. We have secured supply for our continued needs for the Pompe disease program through a long-term supply agreement with Wuxi Biologics. The agreement allows for the continuous manufacture of our biologic to support future clinical needs and our anticipated commercial requirements should we garner regulatory approvals as planned. We have contracts in place to supply miglustat, our small molecule component of AT-GAA, to support both clinical and future commercial requirements.

•Financial strength. Total cash, cash equivalents, and marketable securities as of June 30, 2022 was $386.8 million. Based on the current operating model, we believe that the current cash position, which includes expected revenues, is sufficient to fund our operations and ongoing research programs to achieve self-sustainability. Potential impacts of the COVID-19 pandemic, business development collaborations, pipeline expansion, and investment in manufacturing capabilities could impact our future capital requirements.

Our Commercial Product and Product Candidates

Galafold® (migalastat HCl) for Fabry Disease

Our oral precision medicine Galafold® was granted accelerated approval by the FDA in August 2018 under the brand name Galafold® for the treatment of adults with a confirmed diagnosis of Fabry disease and an amenable galactosidase alpha gene ("GLA") variant based on in vitro assay data. The FDA has approved Galafold® for 350 amenable GLA variants. Galafold® was approved in the E.U. and U.K. in May 2016 as a first-line therapy for long-term treatment of adults and adolescents, aged 16 years and older, with a confirmed diagnosis of Fabry disease and who have an amenable mutation (variant). The approved E.U. and U.K. labels include 1,384 mutations amenable to Galafold® treatment, which represent up to half of all patients with Fabry disease. In countries where mutations are provided only on the amenability website, these 1,384 amenable mutations are now available. Marketing authorization approvals have been granted in over 40 countries around the world, including the U.S., E.U., U.K., Japan, and others. In July 2021, Galafold® was approved in the E.U. for adolescents aged 12 years and older weighing 45 kg or more. We plan to continue to launch Galafold® in additional countries during 2022, including for adolescents aged 12 years and older.

As an orally administered monotherapy, Galafold® is designed to bind to and stabilize an endogenous alpha-galactosidase A ("alpha-Gal A") enzyme in those patients with genetic variants identified as amenable in a GLP cell-based amenability assay. Galafold® is an oral precision medicine intended to treat Fabry disease in patients who have amenable genetic variants, and at this time, it is not intended for concomitant use with ERT.

The Galafold® U.S. patent portfolio encompasses 44 orange book listed patents, including 4 U.S. Composition of Matter patents, of which 27 provide protection through at least 2038.

Next Generation for Fabry Disease

We are committed to continued innovation for all people living with Fabry disease. Our pipeline includes a Fabry gene therapy and an academic research collaboration agreement with the University of Seville to explore next generation pharmacological chaperones for Fabry disease.

Novel ERT for Pompe Disease

We are leveraging our biologics capabilities to develop AT-GAA, a novel treatment paradigm for Pompe disease. AT-GAA consists of a uniquely engineered rhGAA enzyme, ATB200, or cipaglucosidase alfa, with an optimized carbohydrate structure to enhance lysosomal uptake, administered in combination with AT2221, or miglustat, that functions as an enzyme stabilizer. Miglustat binds to and stabilizes ATB200 preventing inactivation of rhGAA in circulation to improve the uptake of active enzyme in key disease-relevant tissues, resulting in increased clearance of accumulated substrate, ("glycogen"). Miglustat is not an active ingredient that contributes directly to glycogen reduction.

In February 2021, we reported topline results from the Phase 3 PROPEL study. Of the Pompe disease patients enrolled, 77% were being treated with alglucosidase alfa (n=95) immediately prior to enrollment (“Switch”) and 23% had never been treated with any ERT (n=28) (“Naïve”). Nearly all patients from the PROPEL study continue to be treated with AT-GAA in the extension clinical study. The clinical data from the PROPEL study, the extension study as well as the Phase 1/2 study were included in the AT-GAA submissions to the FDA and the EMA.

In March 2022, we announced positive long-term data from our ongoing phase 1/2 clinical study. Study participants treated with AT-GAA for up to 36 months demonstrated persistent and durable effects on six-minute walk test distance and measures of motor function and muscle strength, stability, or increase in forced vital capacity, and reductions in biomarkers of muscle damage and disease substrate.

In addition, we are conducting ongoing clinical studies in pediatric patients for both LOPD and infantile-onset Pompe disease ("IOPD") populations.

Next Generation for Pompe Disease

As part of our long-term commitment to provide multiple solutions to address the significant unmet needs of the Pompe disease community, we are also continuing discovery for next-generation genetic medicines for Pompe disease.

CDKL5 Deficiency Disorder

We are researching a potential first-in-class genetic medicine for CDKL5 deficiency disorder consisting of a CDKL5 protein engineered for cross correction, delivered as either a protein replacement or as a gene therapy through our collaboration with Penn. We are collaborating with the LouLou Foundation to assess the natural history of the disease to identify endpoints for potential use in future studies.

Additional Next Generation Programs

We have a number of additional gene therapies in clinical and preclinical development, including potential gene therapies in multiple forms of Batten disease.

Strategic Alliances and Arrangements

We will continue to evaluate business development opportunities as appropriate to build stockholder value and provide us with access to the financial, technical, clinical, and commercial resources necessary to develop and market technologies or products with a focus on rare and orphan diseases. We are exploring potential collaborations, alliances, and other business development opportunities on a regular basis. These opportunities may include business combinations, partnerships, the strategic out-licensing of certain assets, or the acquisition of preclinical-stage, clinical-stage, or marketed products or platform technologies consistent with our strategic plan to develop and provide therapies to patients living with rare and orphan diseases.

Net loss attributable to common stockholders	$	(62,157)		$	(51,225)		$	(10,932)

Net Product Sales. Net product sales increased $3.3 million during the three months ended June 30, 2022 compared to the same period in the prior year. The increase was primarily due to continued growth in the U.S., Europe and Japan markets, partially offset by the $6.7 million unfavorable impact of foreign currency exchange.

Research and Development Expense. The following table summarizes our principal development programs and the out-of-pocket, third-party expenses incurred:


(in thousands)	Three Months Ended June 30,
Projects	2022		2021
Third party direct project expenses
Galafold® (Fabry Disease)	$	3,419	$	1,375
AT-GAA (Pompe Disease)	21,585		23,840
Gene therapy programs	27,225		14,648
Pre-clinical and other programs	—		552
Total third-party direct project expenses	52,229		40,415
Other project costs

Other costs	7,938		6,602
Total other project costs	26,090		22,588
Total research and development costs	$	78,319	$	63,003

The $15.3 million increase in research and development costs was primarily driven by the strategic prioritization of our gene therapy portfolio resulting in the non-recurring expense of a contractual obligation from which we will no longer receive further economic benefit. Additionally, personnel costs increased primarily due to share-based compensation.

Selling, General, and Administrative Expense. Selling, general, and administrative expense increased $11.1 million, primarily driven by the strategic prioritization of our gene therapy portfolio that resulted in the write-off of cloud computing costs and software licensing fees.

Other Income. The $7.0 million variance was primarily related to foreign exchange gains caused by local currency remeasurement of U.S. dollar balances.

Income Tax Expense. The income tax expense for the three months ended June 30, 2022 was $0.9 million. We are subject to income taxes in various jurisdictions. Our tax liabilities are largely dependent on the distribution of pre-tax earnings among the many jurisdictions in which we operate.

Total other project costs	59,224		49,480
Total research and development costs	$	159,836	$	127,120

The $32.7 million increase in research and development costs was primarily due to the strategic prioritization of our gene therapy portfolio resulting in the non-recurring expense of contractual obligations from which we will no longer receive further economic benefit, an increase in personnel costs primarily due to share-based compensation, an increase in the Pompe disease program associated with the timing of manufacturing costs, and an increase in clinical research costs in the Fabry disease program.

Selling, General, and Administrative Expense. Selling, general, and administrative expense increased $22.5 million, primarily driven by the strategic prioritization of our gene therapy portfolio that resulted in the write-off of cloud computing costs and software licensing fees and an increase in share-based compensation and marketing expenses.

Loss on Impairment of Assets. In connection with the strategic prioritization of our gene therapy portfolio, the Company performed an assessment of its assets and recognized a $6.6 million loss on impairment of assets.

Other Income (Expense). The $12.1 million variance was primarily related to foreign exchange gains caused by local currency remeasurement of U.S. dollar balances.

Income Tax Expense. The income tax expense for the six months ended June 30, 2022 was $4.7 million. We are subject to income taxes in various jurisdictions. Our tax liabilities are largely dependent on the distribution of pre-tax earnings among the many jurisdictions in which we operate.

Liquidity and Capital Resources

As a result of our significant research and development expenditures, as well as expenditures to build a commercial organization to support the launch of Galafold®, we have not been profitable and have generated operating losses since we were incorporated in 2002. We have historically funded our operations through stock offerings, Galafold® revenues, debt issuance, collaborations, and other financing arrangements.

Cash Flow Discussion

As of June 30, 2022, we had cash, cash equivalents, and marketable securities of $386.8 million. We invest cash in excess of our immediate requirements in regard to liquidity and capital preservation in a variety of interest-bearing instruments, including obligations of U.S. government agencies and money market accounts. Wherever possible, we seek to minimize the potential effects of concentration and degrees of risk. Although we maintain cash balances with financial institutions in excess of insured limits, we do not anticipate any losses with respect to such cash balances. For more details on the cash, cash equivalents, and marketable securities, refer to "— Note 3. Cash, Cash Equivalents, Marketable Securities, and Restricted Cash," in our Notes to Consolidated Financial Statements.

Net Cash Used in Operating Activities

Net cash used in operations for the six months ended June 30, 2022 was $74.2 million. The components of net cash used in operations included the net loss for the six months ended June 30, 2022 of $147.4 million offset by $43.1 million of stock compensation, $15.6 million of other non-cash adjustments, and a net increase in changes in operating assets and liabilities of $14.5 million. The changes in operating assets and liabilities were primarily due to an increase in accounts payable and accrued expenses of $22.7 million associated with the strategic prioritization of our gene therapy portfolio resulting in the non-recurring expense of contractual obligations from which we will no longer receive further economic benefit and tax accruals, offset by payments of contract manufacturing, third party research and development services, and annual performance bonus. The net cash used in operations was also impacted by an increase in accounts receivable of $4.4 million due to increased commercial sales of Galafold®.

Net cash used in operations for the six months ended June 30, 2021 was $108.3 million. The components of net cash used in operations included the net loss for the six months ended June 30, 2021 of $116.9 million and an overall decrease in cash from changes in operating assets and liabilities of $32.6 million, primarily related to the timing of contract manufacturing and research payments. This was partially offset by $32.1 million of stock compensation and $9.1 million of other non-cash adjustments.

Net Cash Provided by Investing Activities

Net cash provided by investing activities for the six months ended June 30, 2022 was $84.5 million. Our investing activities have consisted primarily of purchases, sales, and maturities of investments and capital expenditures. Net cash provided by investing activities reflects $184.1 million for the sale and redemption of marketable securities, partially offset by $98.3 million for the purchase of marketable securities and $1.2 million for capital expenditures.

Net cash provided by investing activities for the six months ended June 30, 2021 was $112.3 million. Our investing activities have consisted primarily of purchases and sales and maturities of investments and capital expenditures. Net cash provided by investing activities reflects $258.8 million for the sale and redemption of marketable securities, partially offset by $145.3 million for the purchase of marketable securities and $1.2 million for capital expenditures.

Net Cash (Used in) Provided by Financing Activities

Net cash used in financing activities for the six months ended June 30, 2022 was $7.5 million. Net cash used in financing activities primarily reflects the purchase of vested restricted stock units of $9.3 million, partially offset by $1.9 million of proceeds from the exercise of stock options.

Net cash provided by financing activities for the six months ended June 30, 2021 was $11.1 million. Net cash provided by financing activities primarily reflects $19.2 million from the exercise of the remaining outstanding warrants and $6.7 million from the exercise of stock options, partially offset by $14.4 million from the purchase of vested restricted stock units.

Funding Requirements

We expect to incur losses from operations for the foreseeable future primarily due to research and development expenses, including expenses related to conducting clinical trials. Our future capital requirements will depend on a number of factors, including:
