	1. Organization and Reorganization
	Organization
	GrubHub Inc., a Delaware corporation, and its wholly-owned subsidiaries (collectively referred to as the “Company”) provide an online and mobile platform for restaurant pick-up and delivery orders. Diners enter their location through an online interface and the Company displays the menus and other relevant information for restaurants in its network. Orders may be placed directly online or over the phone at no cost to the diner. The Company charges the restaurant a per order commission that is largely fee based.
	Initial Public Offering
	The Company completed an initial public offering (the “IPO”) of its common stock on April 4, 2014. See Note 11, Subsequent Events, for additional details.
	Reorganization and History
	On August 8, 2013, GrubHub Inc. acquired, through a series of transactions, all of the equity interests of each of Seamless North America, LLC, Seamless Holdings Corporation (“Seamless Holdings”) and GrubHub Holdings Inc. pursuant to that certain Reorganization and Contribution Agreement, dated as of May 19, 2013, by and among GrubHub Inc., Seamless North America, LLC, Seamless Holdings, GrubHub Holdings Inc. and the other parties thereto (the “Reorganization Agreement”). Following this transaction, the Company concluded that Seamless Holdings was deemed the acquirer for financial reporting purposes. See Note 3, Acquisitions, for additional details. Accordingly, the acquisition of GrubHub Holdings Inc. has been accounted for as a business combination. The results of operations of GrubHub Holdings Inc. have been included in the Company’s financial statements since August 9, 2013. In February 2014, GrubHub Seamless Inc. was renamed GrubHub Inc.
	The financial position and results of operations of Seamless Holdings and Seamless North America, LLC have been included in the condensed consolidated financial statements for all periods presented.

	2. Significant Accounting Policies
	Basis of Presentation
	The accompanying unaudited condensed consolidated interim financial statements include the accounts of GrubHub Inc. and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. These unaudited condensed consolidated interim financial statements include all wholly owned subsidiaries and reflect all normal and recurring adjustments, as well as any other than normal adjustments as described in the paragraph below, that are, in the opinion of management, necessary for a fair presentation of the results for the interim periods and should be read in conjunction with the Company’s prospectus filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933 on April 7, 2014. All significant intercompany transactions have been eliminated in consolidation. Operating results for the three months ended March 31, 2014 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2014.
	Use of Estimates
	The preparation of condensed consolidated financial statements in accordance with GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets and liabilities and the related disclosures at the date of the financial statements, as well as the reported amounts of revenue and expenses during the periods presented. Estimates include revenue recognition, the allowance for doubtful accounts, website development costs, goodwill, depreciable lives of property and equipment, recoverability of intangible assets with definite lives and other long-lived assets and stock-based compensation. Actual results could differ from these estimates.
	Pro Forma Presentation
	The unaudited pro forma balance sheet and income statement presentation give effect to the following items related to the IPO in April of 2014: (1) issuance of 4,000,000 shares of common stock at a price of $26.00 per share, net of deducted underwriting discounts and estimated offering costs, (2) conversion of 19,284,113 shares of preferred stock into common stock and (3) termination of the put rights on 1,344,236 shares of redeemable common stock. The unaudited pro forma net income per share is computed using the net income divided by pro forma weighted average number of shares outstanding. Pro forma weighted average number of shares outstanding assumes the preferred stock and redeemable common stock conversion had occurred as of January 1, 2014. See Note 11, Subsequent Events, for further discussion of the IPO.
	Reverse Stock Split Ratio
	On April 2, 2014, the Company effected a 1-for-2 reverse stock split of its issued and outstanding common stock and preferred stock. Any fractional shares resulting from the reverse stock split were rounded up to the nearest whole share. All share and per-share amounts for all periods presented in these financial statements have been adjusted retroactively to reflect the reverse stock split.
	Recently Issued Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2013-11 “Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists” (“ASU 2013-11”), which requires that a liability related to an unrecognized tax benefit be presented as a reduction of a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward that the entity intends to use and is available for settlement at the reporting date. ASU 2013-11 was effective for and adopted by the Company in the first quarter of 2014 and will be applied prospectively to unrecognized tax benefits that exist at the effective date with retrospective application permitted. The adoption of ASU 2013-11 impacted the Company’s financial statement presentation and disclosures, but otherwise did not impact the Company’s condensed consolidated financial position, results of operations or cash flows.
	In February 2013, the FASB issued Accounting Standards Update No. 2013-02 “Comprehensive Income (Topic 220): Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income” (“ASU 2013-02”), which requires an entity to disaggregate the total change of each component of other comprehensive income either on the face of the income statement or as a separate disclosure in the notes. ASU 2013-02 was effective for and adopted by the Company in the first quarter of 2013. The adoption of ASU 2013-02 impacted the Company’s financial statement presentation and disclosures, but otherwise did not impact the Company’s condensed consolidated financial position, results of operations or cash flows.

	3. Acquisitions
	GrubHub Holdings Inc.
	On August 8, 2013, the Company acquired all of the equity interests of each of Seamless North America, LLC, Seamless Holdings and GrubHub Holdings Inc. pursuant to the Reorganization Agreement. In February 2014, GrubHub, Inc. changed its name to GrubHub Holdings Inc. The Company issued 23,318,580 shares of common stock and 8,098,430 shares of preferred stock to GrubHub Holdings Inc. in exchange for all of GrubHub Holdings Inc.’s equity interests (the “Merger”). The Company concluded that Seamless Holdings was deemed the acquirer for financial reporting purposes based on key deciding factors such as a majority ownership and majority of the board of director seats. Accordingly, the acquisition of GrubHub Holdings Inc. has been accounted for as a business combination. The results of operations of GrubHub Holdings Inc. have been included in the Company’s financial statements since August 9, 2013. GrubHub Holdings Inc. provides online food ordering through its website grubhub.com, and also operates allmenus.com, a website that stores and displays approximately 275,000 menus. The Merger has expanded the Company’s existing markets and access to new customers and created revenue and cost synergies which management believes will contribute to future profits.
	The fair value of the equity issued to GrubHub Holdings Inc. in connection with the Merger was approximately $421.5 million. The value of the equity was determined using the estimated fair value of the stock of GrubHub Holdings Inc. at the merger date based on a valuation of GrubHub Holdings Inc. performed by management. The assets acquired and liabilities assumed were recorded at their estimated fair values as of August 8, 2013. The fair value of the equity of $421.5 million included approximately $11.0 million related to the fair value of the replacement awards that were attributed to the pre-combination service period for GrubHub Holdings Inc. option holders. The fair value of the replacement awards was determined using the Black-Scholes option pricing model. Post combination expense of $12.5 million is expected to be recognized post-Merger for the unrecognized compensation expense related to GrubHub Holdings Inc. stock options. See Note 7, Stock-Based Compensation, for further details.
	The excess of the consideration transferred in the acquisition over the net amounts assigned to the fair value of the assets acquired was recorded as goodwill, which represents the opportunity to expand existing markets and access new customers and to create revenue and cost synergies that management believes will contribute to future profits. The goodwill is not deductible for income tax purposes.
	The Company incurred certain expenses directly and indirectly related to the Merger of $0.4 million during the three months ended March 31, 2013, which were recognized in general and administrative expenses within the condensed consolidated statements of operations.
	The following table summarizes the August 8, 2013 acquisition-date fair value of the assets and liabilities acquired in connection with the GrubHub Holdings Inc. business combination:
		(in thousands)
	Cash and cash equivalents	$	13,266
	Accounts receivable		2,108
	Other identifiable assets		4,422

	Goodwill		239,346
	Liabilities assumed		(10,602	)
	Trademarks		85,276
	Total net assets acquired	$	421,485
	The estimated fair values of the intangible assets acquired were determined based on a combination of the income, cost, and market approaches to measure the fair value of the customer (restaurant) relationships, developed technology and trademarks. The fair value of the trademarks was measured based on the relief from royalty method. The cost approach, specifically the cost to recreate method, was used to value the developed technology. The income approach, specifically the multi-period excess earnings method, was used to value the customer (restaurant) relationships. These fair value measurements were based on significant inputs not observable in the market and thus represent Level 3 measurements under the fair value hierarchy.
	The results of operations related to GrubHub Holdings Inc. have been included in the Company’s financial statements since August 9, 2013.
	The following unaudited pro forma information presents a summary of the operating results of the Company for the three months ended March 31, 2013 as if GrubHub Inc. had acquired GrubHub Holdings Inc. as of January 1, 2013:

	In August 2011, Ameranth filed a patent infringement action against a number of defendants, including GrubHub Holdings Inc., in the U.S. District Court for the Southern District of California (the “Court”), Case No. 3:11-cv-1810 (“’1810 action”). In September 2011, Ameranth amended its complaint in the ’1810 action to also accuse Seamless North America, LLC of infringement. Ameranth alleged that the GrubHub Holdings Inc. and Seamless North America, LLC ordering systems, products and services infringe claims 12 and 15 of U.S. Patent No. 6,384,850 (“’850 patent”) and claims 11 through 15 of U.S. Patent No. 6,871,325 (“’325 patent”).
	In March 2012, Ameranth initiated eight additional actions for infringement of a third, related patent, U.S. Patent No. 8,146,077 (“’077 patent”), in the same forum, including separate actions against GrubHub Holdings Inc., Case No. 3:12-cv-739 (“’739 action”), and Seamless North America, LLC, Case No. 3:12-cv-737 (“’737 action”). In August 2012, the Court severed the claims against GrubHub Holdings Inc. and Seamless North America, LLC in the ’1810 action and consolidated them with the ’739 action and the ’737 action, respectively. Later, the Court consolidated these separate cases against GrubHub Holdings Inc. and Seamless North America, LLC, along with the approximately 40 other cases Ameranth filed in the same district, with the original ’1810 action. In their answers, GrubHub Holdings Inc. and Seamless North America, LLC denied infringement and interposed various defenses, including non-infringement, invalidity, unenforceability and inequitable conduct.
	On November 26, 2013, the consolidated case was stayed pending the disposition of petitions for post-grant review of all the patents in the suit. These petitions were filed in the United States Patent and Trademark Office (the “PTO”) under the new Transitional Program for Covered Business Method Patents (the “CBM proceedings”). The CBM proceedings resulted in a March 26, 2014 ruling denying defendants’ petitions on the claims most relevant to GrubHub Holdings Inc. and Seamless North America LLC. The consolidated case remains stayed.
	No trial date has been set for this case. The Company believes this case lacks merit and that it has strong defenses to all of the infringement claims. The Company intends to defend the suit vigorously. However, the Company is unable to predict the likelihood of success of Ameranth’s infringement claims and is unable to predict the likelihood of success of its counterclaims. The Company has not recorded an accrual related to this lawsuit as of March 31, 2014, as it does not believe a material loss is probable. It is a reasonable possibility that a loss may be incurred; however, the possible range of loss is not estimable given the early stage of the dispute and the uncertainty as to whether the claims at issue are with or without merit, will be settled out of court, or will be determined in the Company’s favor, whether the Company may be required to expend significant management time and financial resources on the defense of such claims, and whether the Company will be able to recover any losses under its insurance policies.
	In addition to the matters described above, from time to time, the Company is involved in various other legal proceedings arising from the normal course of business activities.
	Indemnification
	In connection with the Merger, the Company agreed to indemnify Aramark Holdings for negative income tax consequences associated with the October 2012 spin-off of Seamless Holdings that were the result of certain actions taken by the Company, including its solicitation of acquirers to purchase the Company prior to October 29, 2014, and in certain other instances, subject to a $15.0 million limitation. Management is not aware of any actions that would impact the indemnification obligation.
	Restructuring
	On November 20, 2013 the Company announced plans to close its Sandy, Utah office location in 2014. The Company recorded a restructuring accrual in the condensed consolidated balance sheets for severance and payroll related benefits as a result of the restructuring announcement. This amount represents the service vesting requirements for identified employees required to work through the expected closure date of the facility of December 31, 2014. The Company estimates total restructuring costs to be incurred will be approximately $1.2 million. For the three months ended March 31, 2014, restructuring expense of $0.3 million was recognized in general and administrative expense in the condensed consolidated statements of operations.
	The following table summarizes the Company’s restructuring activity during the three months ended March 31, 2014:

	Restructuring accrual balance at December 31, 2013	$	176

Stock-Based Compensation	'
	7. Stock-Based Compensation
	As part of the Reorganization Agreement, the Company was required to replace GrubHub Holdings Inc.’s share-based payment awards. The fair value of the replacement awards attributable to pre-combination services at the time of the Merger was approximately $11.0 million, which was included as additional consideration transferred in the business combination in the total purchase price of $421.5 million. The fair value of the replacement options attributable to post combination services was approximately $12.5 million and will be recognized as compensation cost in the Company’s post-Merger consolidated financial statements over the remaining vesting period.
	The Company granted 1,598,990 and 368,750 stock options during the three months ended March 31, 2014 and 2013, respectively. The fair market value of each stock option award was estimated based on the assumptions below as of the grant date using the Black-Scholes-Merton option pricing model. Expected volatilities are based on historical volatilities of comparable publicly traded companies. The Company uses historical data to estimate option exercises and employee terminations within the valuation model. Separate groups of employees that have similar historical exercise behavior are considered separately for valuation purposes. The expected term of the award is estimated using a simplified method. The fair value at grant date was determined considering the performance of the Company at the grant date as well as future growth and profitability expectations by applying market and income approaches. The risk-free rate for the period within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The assumptions used to determine the fair market value of the stock options granted during the three months ended March 31, 2014 and 2013 were as follows:
			2014			2013
	Weighted average fair value of options granted		$	12.95		$	1.66
	Average risk-free interest rate			2.02	%		1.1	%
	Expected stock price volatilities(a)			50.7	%		53.8	%
	Dividend yield			None			None
	Expected stock option life			6.31			6.06
		a)	There was no active external or internal market for the Company’s shares until April of 2014. Thus, it was not possible to estimate the expected volatility of the Company’s share price in estimating fair value of options granted. As a substitute for such volatility, the Company used the historical volatility of comparable companies.
	Stock option awards as of December 31, 2013 and March 31, 2014, and changes during the three months ended March 31, 2014, were as follows:
			Options			Weighted			Average		Weighted
						Average			Intrinsic		Average
						Exercise Price			Value		Exercise Term
									(thousands)		(years)
	Outstanding at December 31, 2013			7,669,553		$	4.08		$	56,844		8.29
	Granted			1,598,990			13.7
	Forfeited			(166,876	)		5.86
	Exercised			(418,463	)		3.38
	Outstanding at March 31, 2014			8,683,204			5.85			131,628		8.4
	Vested and expected to vest March 31, 2014			7,442,473			5.67			114,077		8.38
	Exercisable at March 31, 2014			3,368,799		$	3.8		$	57,945		8.02
	The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between the fair value of the common stock on March 31, 2014 and December 31, 2013, respectively, and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their in-the-money options on each date. This amount will change in future periods based on the fair market value of the Company’s stock and the number of options outstanding. The aggregate intrinsic value of awards exercised during the three months ended March 31, 2014 was $6.5 million.
	The stock options vest over different lengths of time depending upon the grantee. Compensation expense is recognized over the vesting period. The Company recorded compensation expense of $2.4 million and $0.6 million for the three months ended March 31, 2014 and 2013, respectively. As of March 31, 2014, total unrecognized compensation cost, adjusted for estimated forfeitures, related to non-vested stock options was $29.8 million and is expected to be recognized over a weighted average period of 3.37 years.

Stockholders' Equity	'
	8. Stockholders’ Equity
	As of March 31, 2014 and December 31, 2013, the Company was authorized to issue two classes of stock: common stock and Series A preferred stock. Each share of Series A preferred stock was convertible, at the option of the holder thereof, into common stock on a one-for-one basis, subject to adjustment as defined in the Company’s amended and restated certificate of incorporation. The Company entered into a stockholders agreement in 2013 with certain stockholders. The agreement prevented those stockholders from transferring their shares without the consent of a majority of the stockholders.
	On April 4, 2014, the Company completed the IPO in which the Company issued and sold 4,000,000 shares of common stock at a public offering price of $26.00 per share. The Company received net proceeds of $95.5 million after deducting underwriting discounts and commissions of $6.5 million and other offering expenses of approximately $2.0 million. Upon the closing of the IPO, the stockholder’s agreement ceased to be in effect.
	Common Stock
	Each holder of common stock will have one vote per share of common stock held on all matters that are submitted for stockholder vote. Upon liquidation, the common stock was junior to the rights and preferences of the Series A preferred stock as of March 31, 2014 and December 31, 2013. At March 31, 2014 and December 31, 2013, there were 500,000,000 and 165,000,000 shares of common stock authorized, respectively. At March 31, 2014 and December 31, 2013, there were 54,083,204 and 53,757,437 shares issued and outstanding, respectively. The Company did not hold any shares as treasury shares as of March 31, 2014 or December 31, 2013.
	Series A Preferred Stock
	In the event of a liquidation event, the holders of Series A preferred stock were entitled to receive pari passu to each other, and prior in preference to any distribution of any assets of the Company to the holders of common stock. The Series A preferred stock had a liquidation preference of an amount per share equal to the original Series A preferred stock issue price. The aggregate liquidation preference of the Series A preferred stock as of March 31, 2014 and December 31, 2013 was approximately $86.2 million.
	Upon the closing of the IPO on April 4, 2014, all shares of the Company’s then-outstanding convertible Series A preferred stock automatically converted on a one-for-one basis into an aggregate of 19,284,113 shares of common stock.
	Redeemable Common Stock
	As of March 31, 2014 and December 31, 2013, there were 1,344,236 shares of common stock with put rights that would require the Company to repurchase these shares at fair value (as defined in the stockholders agreement) determined at the redemption date. As the redemption price is equivalent to the fair value of the instrument, the Company adjusted the carrying value of the redeemable common stock to its fair value with an adjustment to equity. The fair value of the redeemable common stock increased to $35.0 million as of March 31, 2014 from $18.4 million at December 31, 2013. The Company had an annual redemption limit of $4.0 million. These put rights were terminated upon the closing of the IPO on April 4, 2014.
	The Company’s equity as of December 31, 2013 and March 31, 2014, and changes during the three months ended March 31, 2014, were as follows:

	9. Earnings Per Share Attributable to Common Stockholders
	Basic earnings per share is computed by dividing net income attributable to common stockholders by the weighted average number of common shares outstanding during the period without consideration for common stock equivalents. Diluted net income per share attributable to common stockholders is computed by dividing net income by the weighted average number of common shares outstanding during the period and potentially dilutive common stock equivalents, except in cases where the effect of the common stock equivalent would be antidilutive. Potential common stock equivalents consist of common stock issuable upon exercise of stock options using the treasury stock method and common stock issuable upon conversion of the Series A preferred stock. Upon the closing of the IPO, all shares of the Company’s then-outstanding convertible Series A preferred stock automatically converted into an aggregate of 19,284,113 shares of common stock.

Fair Value Measurement	'
	10. Fair Value Measurement
	Certain assets and liabilities are required to be recorded at fair value on a recurring basis. The Company applied the following methods and assumptions in estimating its fair value measurements: cash equivalents are comprised of highly liquid investments, including money market funds and certificates of deposit with original maturities of less than three months. The fair value measurement of these assets is based on quoted market prices in active markets and, therefore, these assets are recorded at fair value on a recurring basis and classified as Level 1 in the fair value hierarchy. Redeemable common stock consisted of put rights the Company granted to certain shareholders which required common shares to be repurchased at fair value (as defined in the stockholders agreement) determined as of the redemption date. The fair value measurement of redeemable common stock is based on Level 3 inputs as defined in the fair value hierarchy. Accounts receivable and accounts payable approximate fair value due to their generally short-term maturities.
	The following table presents the balances of assets measured at fair value based on Level 1 inputs on a recurring basis as of March 31, 2014 and December 31, 2013:
			March 31, 2014		December 31, 2013
			(in thousands)
	Cash equivalents		$	4,201	$	4,200
	The fair value of the Company’s redeemable common stock, determined to be Level 3 under the fair value hierarchy, was measured based on the required redemption at the most recent fair value of the common stock. The following table presents the fair value, valuation techniques and related unobservable inputs for these Level 3 measurements as of March 31, 2014 and December 31, 2013:

Estimates include revenue recognition, the allowance for doubtful accounts, website development costs, goodwill, depreciable lives of property and equipment, recoverability of intangible assets with definite lives and other long-lived assets and stock-based compensation. Actual results could differ from these estimates.
Pro Forma Presentation	'
	Pro Forma Presentation

ASU 2013-11 was effective for and adopted by the Company in the first quarter of 2014 and will be applied prospectively to unrecognized tax benefits that exist at the effective date with retrospective application permitted. The adoption of ASU 2013-11 impacted the Company’s financial statement presentation and disclosures, but otherwise did not impact the Company’s condensed consolidated financial position, results of operations or cash flows.
	In February 2013, the FASB issued Accounting Standards Update No. 2013-02 “Comprehensive Income (Topic 220): Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income” (“ASU 2013-02”), which requires an entity to disaggregate the total change of each component of other comprehensive income either on the face of the income statement or as a separate disclosure in the notes. ASU 2013-02 was effective for and adopted by the Company in the first quarter of 2013. The adoption of ASU 2013-02 impacted the Company’s financial statement presentation and disclosures, but otherwise did not impact the Company’s condensed consolidated financial position, results of operations or cash flows.
