Accounting Policies [Abstract]
Description of business and summary of significant accounting policies	Description of business and summary of significant accounting policies Description of business Pinterest was incorporated in Delaware in 2008 and is headquartered in San Francisco, California. Pinterest is a visual discovery engine that people around the globe use to find the inspiration to create a life they love. We generate revenue by delivering ads on our website and mobile application. Basis of presentation and consolidation We prepared the accompanying consolidated financial statements in accordance with generally accepted accounting principles in the United States ("GAAP"). The consolidated financial statements include the accounts of Pinterest, Inc. and its wholly owned subsidiaries. We have eliminated all intercompany balances and transactions. Reclassifications We have reclassified certain amounts in prior periods to conform with current presentation. Use of estimates Preparing our consolidated financial statements in conformity with GAAP requires us to make estimates and judgments that affect amounts reported in the consolidated financial statements and accompanying notes. We base these estimates and judgments on historical experience and various other assumptions that we consider reasonable. GAAP requires us to make estimates and assumptions in several areas, including the fair values of financial instruments, assets acquired and liabilities assumed through business combinations, share-based awards, and contingencies as well as the collectability of our accounts receivable, the useful lives of our intangible assets and property and equipment, the incremental borrowing rate we use to determine our operating lease liabilities, and revenue recognition, among others. Actual results could differ materially from these estimates and judgments. Segments We operate as a single operating segment. Our chief operating decision maker is our Chief Executive Officer ("CEO"), who reviews financial information presented on a consolidated basis, accompanied by disaggregated information about our revenue, for purposes of making operating decisions, assessing financial performance and allocating resources. Revenue recognition We generate revenue by delivering ads on our website and mobile application. We recognize revenue only after transferring control of promised goods or services to customers, which occurs when a user clicks on an ad contracted on a CPC basis, views an ad contracted on a CPM basis or views a video ad contracted on a CPV basis. We typically bill customers on a CPC, CPM or CPV basis, and our payment terms vary by customer type and location. The term between billing and payment due dates is not significant. We recognize revenue only after satisfying our contractual performance obligations. We occasionally offer customers free ad inventory. When contracts with our customers contain multiple performance obligations, we allocate the overall transaction price, which is the amount of consideration to which we expect to be entitled in exchange for promised goods or services, to each of the distinct performance obligations based on their relative standalone selling prices. We generally determine standalone selling prices based on the effective price charged per contracted click, impression or view, and we do not disclose the value of unsatisfied performance obligations because the original expected duration of our contracts is generally less than one year. We record sales commissions in sales and marketing as incurred because we would amortize these over a period of less than one year. Deferred revenue was not material as of December 31, 2022 and 2021. Cost of revenue Cost of revenue consists primarily of expenses associated with the delivery of our service, including the cost of hosting our website and mobile application. Cost of revenue also includes personnel-related expense, including salaries, benefits and share-based compensation for employees on our operations teams, payments associated with partner arrangements, credit card and other transaction processing fees, amortization of acquired intangible assets and allocated facilities and other supporting overhead costs. Share-based compensation Restricted stock units ("RSUs") granted under our 2009 Stock Plan (the "2009 Plan") are subject to both a service condition, which is typically satisfied over four years, and a performance condition, which was deemed satisfied upon the pricing of our initial public offering ("IPO"). We did not record any share-based compensation expense for our RSUs prior to our IPO because the performance condition had not yet been satisfied. Upon pricing our IPO, we recorded cumulative share-based compensation expense using the accelerated attribution method for those RSUs granted under our 2009 Plan for which the service condition had been satisfied at that date. We record the remaining unrecognized share-based compensation expense over the remainder of the requisite service period. RSUs, restricted stock awards ("RSAs"), and stock options granted under our 2019 Omnibus Incentive Plan (the "2019 Plan") are subject only to a service condition, which is typically satisfied over four years. We record share-based compensation expense for these RSUs, RSAs and stock options on a straight-line basis over the requisite service period. We measure RSUs and RSAs based on the fair market value of our common stock on the grant date and stock options based on their estimated grant date fair values, which we determine using the Black-Scholes option-pricing model. We record the resulting expense in our consolidated statements of operations over the requisite service period, which is generally four years, and we account for forfeitures as they occur. Income taxes We account for income taxes using the asset and liability method. We recognize deferred tax assets and liabilities for temporary differences between the financial reporting and tax bases of assets and liabilities using the enacted statutory tax rates in effect for the years in which we expect the differences to reverse. We establish valuation allowances to reduce deferred tax assets to the amounts we believe it is more likely than not we will be able to realize. We recognize tax benefits from uncertain tax positions when we believe it is more likely than not that the tax position is sustainable on examination by tax authorities based on its technical merits. We recognize taxes on Global Intangible Low-Taxed Income as incurred. Advertising expenses We record advertising expenses as incurred and include these in sales and marketing in the consolidated statements of operations. Advertising expenses were $139.7 million, $94.7 million and $30.3 million for the years ended December 31, 2022, 2021 and 2020, respectively. Marketable securities We invest in highly liquid corporate debt securities, U.S. treasury securities, asset-backed securities, U.S. government agency securities, municipal securities, non-U.S. government and supranational bonds and certificates of deposit. We classify marketable investments with stated maturities of ninety days or less from the date of purchase as cash equivalents and those with stated maturities greater than ninety days from the date of purchase as marketable securities. We classify our marketable securities as available-for-sale investments in our current assets because they are available for use to support current operations. We carry our marketable investments at fair value and record unrealized gains or losses, net of taxes, in accumulated other comprehensive loss in stockholders’ equity. We determine realized gains and losses on the sale of marketable investments using a specific identification method and record these and any expected credit losses in interest expense and other income (expense), net. Fair value measurements We account for certain assets and liabilities at fair value, which is the amount we believe market participants would be willing to receive to sell an asset or pay to transfer a liability in an orderly transaction. We categorize these assets and liabilities into the three levels below based on the degree to which the inputs we use to measure their fair values are observable in active markets. We use the most observable inputs available to us when measuring fair value. • Level 1: Observable inputs such as quoted prices for identical assets or liabilities in active markets • Level 2: Observable inputs such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical assets or liabilities in inactive markets, or inputs that are derived principally from or corroborated by observable market data or other means • Level 3: Unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities Accounts receivable, net of allowances We record accounts receivable at the original invoiced amount. We maintain an allowance for credit losses for any receivables we may be unable to collect. We estimate uncollectible receivables based on our receivables’ age, our customers’ credit quality and current economic conditions, among other factors that may affect our customers’ ability to pay. We also maintain an allowance for sales credits, which we determine based on historical credits issued to customers. We include the allowances for credit losses and sales credits in accounts receivable, net in the consolidated balance sheets. Property and equipment We carry property and equipment at cost less accumulated depreciation and calculate depreciation using the straight-line method over our assets’ estimated useful lives, which are generally: Property and Equipment Useful Life Computer and network equipment 3 years Furniture and fixtures 4 years Leasehold improvements Lesser of estimated useful life or remaining lease term Leases and operating lease incremental borrowing rate We lease office space under operating leases with expiration dates through 2033. We determine whether an arrangement constitutes a lease at inception and record lease liabilities and right-of-use assets on our consolidated balance sheets at lease commencement. We measure lease liabilities based on the present value of the total lease payments not yet paid discounted based on the more readily determinable of the rate implicit in the lease or our incremental borrowing rate, which is the estimated rate we would be required to pay for a collateralized borrowing equal to the total lease payments over the term of the lease. We estimate our incremental borrowing rate based on an analysis of publicly traded debt securities of companies with credit and financial profiles similar to our own. We measure right-of-use assets based on the corresponding lease liability adjusted for (i) payments made to the lessor at or before the commencement date, (ii) initial direct costs we incur and (iii) tenant incentives under the lease. We begin recognizing rent expense when the lessor makes the underlying asset available to us, we do not assume renewals or early terminations unless we are reasonably certain to exercise these options at commencement and we do not allocate consideration between lease and non-lease components. For short-term leases, we record rent expense in our consolidated statements of operations on a straight-line basis over the lease term and record variable lease payments as incurred. Business combinations We include the results of operations of businesses that we acquire in our consolidated financial statements beginning on their respective acquisition dates. We allocate the fair value of the purchase consideration to the assets acquired and liabilities assumed based on their estimated fair values. When the fair value of the purchase consideration exceeds the fair values of the identifiable assets and liabilities acquired, we record the excess as goodwill. Our estimates of fair value are based on assumptions we believe to be reasonable but which are inherently uncertain and unpredictable, and as a result, actual results may differ from estimates. During the measurement period, which is one year from the acquisition date, we may record adjustments to the assets and liabilities acquired with the corresponding offset to goodwill. Any adjustments after the measurement period are reflected in our consolidated statements of operations. Long-lived assets, including goodwill and intangible assets We record definite-lived intangible assets at fair value less accumulated amortization. We calculate amortization using the straight-line method over the assets’ estimated useful lives of up to ten years. We review our property and equipment and intangible assets for impairment whenever events or circumstances indicate that an asset’s carrying value may not be recoverable. We measure recoverability by comparing an asset’s carrying value to the future undiscounted cash flows that we expect it to generate. If this test indicates that the asset’s carrying value is not recoverable, we record an impairment charge to reduce the asset’s carrying value to its fair value. In the fourth quarter of 2022 we recorded $9.4 million of impairment charges for acquired intangible assets. We did not record any other material property and equipment or intangible asset impairments during the periods presented. We review goodwill for impairment at least annually or more frequently if current circumstances or events indicate that the fair value of our single reporting unit may be less than its carrying value. We did not record any goodwill impairment during the periods presented. Website development costs We capitalize costs to develop our website and mobile application when preliminary development efforts are successfully completed, management has authorized and committed project funding, and it is probable that the project will be completed and the software will be used as intended. Due to the iterative process by which we perform upgrades and the relatively short duration of our development projects, development costs meeting our capitalization criteria were not material during the periods presented. Loss contingencies We are involved in various lawsuits, claims and proceedings that arise in the ordinary course of business. We record a liability for these when we believe it is probable that we have incurred a loss and can reasonably estimate the loss. We regularly evaluate current information to determine whether we should adjust a recorded liability or record a new one. Foreign currency The functional currency of our international subsidiaries is generally their local currency. We translate these subsidiaries’ financial statements into U.S. dollars using month-end exchange rates for assets and liabilities and average exchange rates for revenue and costs and expenses. We record translation gains and losses in accumulated other comprehensive loss in stockholders’ equity. We record foreign exchange gains and losses in interest expense and other income (expense), net. Our net foreign exchange gains and losses were not material for the periods presented. Concentration of business risk We have an agreement with Amazon Web Services (“AWS”) to provide the cloud computing infrastructure we use to host our website, mobile application and many of the internal tools we use to operate our business. We are currently required to maintain a substantial majority of our monthly usage of certain compute, storage, data transfer and other services on AWS. Any transition of the cloud services currently provided by AWS to another cloud services provider would be difficult to implement and would cause us to incur significant time and expense. Concentration of credit risk Financial instruments that may potentially expose us to concentrations of credit risk primarily consist of cash, cash equivalents, marketable securities and restricted cash. Our investment policy is meant to preserve capital and maintain liquidity. The policy limits our marketable investments to investment-grade securities and limits our credit exposure by limiting our concentration in any one corporate issuer or sector and by establishing a minimum credit rating for marketable investments we purchase. Although we deposit cash and marketable investments with multiple financial institutions, our deposits may exceed insurable limits. No customer accounted for more than 10% of our revenue for the years ended December 31, 2022, 2021 and 2020. Our accounts receivable are generally unsecured. We monitor our customers’ credit quality on an ongoing basis and maintain reserves for estimated credit losses. Bad debt expense was not material for the years ended December 31, 2022, 2021 and 2020.

Business Combination and Asset Acquisition [Abstract]
Acquisition	Acquisition On June 10, 2022, we acquired all outstanding shares of The Yes Platform, Inc. (“The Yes”), an AI powered shopping platform for fashion. We believe the acquisition of The Yes will help accelerate our vision for Pinterest to be the home of taste-driven shopping. The total purchase consideration was $87.6 million in cash. Of this, we attributed $15.0 million to customer relationships, $13.6 million to developed technology, and $60.0 million to goodwill. Goodwill represents the synergies we expect to realize from the acquisition and the assembled workforce and is not deductible for tax purposes. We included the results of The Yes’s operations in our consolidated financial statements beginning on the acquisition date. The acquisition did not have a material impact on our consolidated financial statements so we have not presented historical and pro forma disclosures. In the fourth quarter of 2022, we recorded impairment charges of $9.4 million related to the customer relationships and developed technology. Refer to Note 6 for detail.

Amortization expense was $24.9 million, $1.3 million, and $1.0 million for the years ended December 31, 2022, 2021 and 2020, respectively. During the fourth quarter of 2022, we evaluated the acquired intangible assets from The Yes for impairment due to the departure of certain key employees. We concluded that the fair values of the customer relationships and developed technology were impaired and recorded impairment charges of $6.3 million and $3.1 million to sales and marketing and cost of revenue, respectively.

Under the new pricing addendum, we are required to purchase at least $3,250.0 million of cloud services from AWS through April 2029. If we fail to do so, we are required to pay the difference between the amount we spend and the required commitment amount. As of December 31, 2022, our remaining contractual commitment is $2,357.1 million. We expect to meet our remaining commitment. Legal matters We are involved in various lawsuits, claims and proceedings that arise in the ordinary course of business, including those described below. While the results of legal matters are inherently uncertain, we do not believe there is a reasonable possibility that the ultimate resolution of these matters, either individually or in aggregate, will have a material adverse effect on our business, financial position, results of operations or cash flows. In November and December 2020, certain of our executives and members of our board of directors were named as defendants in shareholder derivative lawsuits filed in the U.S. District Court for the Northern District of California. Pinterest was also named as a nominal defendant. The lawsuits purport to assert claims for breach of fiduciary duty in connection with allegations of gender and racial discrimination at Pinterest. In addition, the lawsuits purport to assert claims for waste, abuse of control, aiding and abetting breaches of fiduciary duties, unjust enrichment, and violations of Section 14(a) of the Exchange Act. The complaints seek declaratory and injunctive relief, corporate governance changes, monetary damages, interest, disgorgement, and fees and costs. On July 14, 2021, another shareholder derivative complaint with similar allegations was filed in the same court and was subsequently related to the earlier action. The cases were referred to a magistrate judge for mediation, and the proceedings were stayed during the pendency of that mediation. On November 24, 2021, the parties entered into a stipulation of settlement. A final approval for the settlement was granted on May 26, 2022. The court granted a portion of the attorneys' fees sought by Plaintiffs, while another portion remains contingent on certain conditions being fulfilled within two years of the settlement approval. We don't believe that these fees will be material to our financial position. In March 2021, certain of our executives and members of our board of directors were named as defendants in a shareholder derivative lawsuit filed in the Delaware Chancery Court. Pinterest was also named as a nominal defendant. The complaint alleged that executives and members of the board breached their fiduciary duties to the company in connection with allegations of gender and racial discrimination at Pinterest. The complaint sought damages, litigation costs, and interest. On May 10, 2021, the court stayed this lawsuit in light of the related pending case in the Northern District of California. On July 21, 2022 the matter was dismissed. Revolving credit facility In October 2022, we entered into an amended and restated five-year $400.0 million revolving credit facility (the “2022 revolving credit facility”), which replaced our previous $500.0 million revolving credit facility entered into in November 2018. The 2022 revolving credit facility also contains an accordion option which, if exercised, would allow us to increase the aggregate commitments by up to $405.0 million provided we are able to secure additional lender commitments and satisfy certain other conditions. Interest on any borrowings under the 2022 revolving credit facility accrues at either an adjusted term Secured Overnight Financing Rate ("SOFR") plus 0.10% and a margin of 1.50% or at an alternative base rate plus a margin of 0.50%, at our election, and we are required to pay an annual commitment fee that accrues at 0.15% per annum on the unused portion of the aggregate commitments under the 2022 revolving credit facility. The 2022 revolving credit facility also allows us to issue letters of credit, which reduce the amount we can borrow. We are required to pay a fee that accrues at 0.125% per annum on the average aggregate daily maximum amount available to be drawn under any outstanding letters of credit. The 2022 revolving credit facility contains customary conditions to borrowing, events of default and covenants, including covenants that restrict our ability to incur indebtedness, grant liens, make distributions to holders of our stock or the stock of our subsidiaries, make investments or engage in transactions with our affiliates. The 2022 revolving credit facility also contains a financial maintenance covenant: a maximum net leverage ratio of consolidated debt to consolidated EBITDA no greater than 3.50 to 1.00, subject to an increase up to 4.00 to 1.00 for a certain period following an acquisition. The obligations under the 2022 revolving credit facility are secured by liens on substantially all of our domestic assets, including certain domestic intellectual property assets. Our total borrowing capacity under the revolving credit facility is $400.0 million as of December 31, 2022. We have not issued any letters of credit and there are no amounts outstanding under the 2022 revolving credit facility as of December 31, 2022.

Share-Based Payment Arrangement [Abstract]
Share-based compensation	Share-based compensation Equity incentive plan In June 2009, our board of directors adopted and approved our 2009 Plan, which provides for the issuance of stock options, RSAs and RSUs to qualified employees, directors and consultants. Stock options granted under our 2009 Plan have a maximum life of 10 years and an exercise price not less than 100% of the fair market value of our common stock on the date of grant. RSUs granted under our 2009 Plan have a maximum life of seven years. No shares of our common stock were reserved for future issuance under our 2009 Plan as of December 31, 2022. Our 2019 Plan became effective upon closing of our initial public offering and succeeds our 2009 Plan. Our 2019 Plan provides for the issuance of stock options, RSAs, RSUs and other equity- or cash-based awards to qualified employees, directors and consultants. Stock options granted under our 2019 Plan have a maximum life of 10 years and an exercise price not less than 100% of the fair market value of our common stock on the date of grant. 117,384,569 shares of our Class A common stock were reserved for future issuance under our 2019 Plan as of December 31, 2022. The number of shares of our Class A common stock available for issuance under the 2019 Plan will be increased by the number of shares of our Class B common stock subject to awards outstanding under our 2009 Plan that would, but for the terms of the 2019 Plan, have returned to the share reserves of the 2009 Plan pursuant to the terms of such awards, including as the result of forfeiture, repurchase, expiration or retention by us in order to satisfy an award’s exercise price or tax withholding obligations. In addition, the number of shares of our Class A common stock reserved for issuance under our 2019 Plan will automatically increase on the first day of each fiscal year through and including January 1, 2029, in an amount equal to 5% of the total number of shares of our Class A common stock and our Class B common stock outstanding on the last day of the calendar month before the date of each automatic increase, or a lesser number of shares determined by our board of directors. Stock option activity Stock option activity during the year ended December 31, 2022, was as follows (in thousands, except per share amounts): Stock Options Outstanding Shares Weighted-Average Exercise Price Weighted-Average Remaining Contractual Term Aggregate Intrinsic Value (1) (in years) Outstanding as of December 31, 2021 16,141 $ 3.19 1.9 $ 535,118 Granted 8,553 19.96 Exercised (8,895) 1.45 Outstanding as of December 31, 2022 15,799 $ 13.25 6.1 $ 174,165 Exercisable as of December 31, 2022 7,498 $ 5.74 2.4 $ 138,979 (1) We calculate intrinsic value based on the difference between the exercise price of in-the-money-stock options and the fair value of our common stock as of the respective balance sheet date. The total grant-date fair value of stock options vested during the years ended December 31, 2022, 2021 and 2020 was $9.5 million, $3.2 million and $3.3 million, respectively. The aggregate intrinsic value of stock options exercised during the years ended December 31, 2022, 2021 and 2020 was $180.2 million, $511.4 million and $1,023.9 million, respectively. Restricted stock unit and restricted stock award activity RSU and RSA activity during the year ended December 31, 2022, was as follows (in thousands, except per share amounts): Restricted Stock Units and Restricted Stock Awards Outstanding Shares Weighted Average Grant Date Fair Value Outstanding as of December 31, 2021 36,258 $ 30.84 Granted 52,480 21.91 Released (22,763) 25.41 Forfeited (11,457) 26.31 Outstanding as of December 31, 2022 54,518 $ 25.46 Share-based compensation Share-based compensation expense during the years ended December 31, 2022, 2021 and 2020, was as follows (in thousands): Year Ended December 31, 2022 2021 2020 Cost of revenue $ 7,629 $ 7,438 $ 7,865 Research and development 324,161 309,715 218,718 Sales and marketing 99,467 52,691 35,645 General and administrative 65,866 45,538 58,792 Total share-based compensation $ 497,123 $ 415,382 $ 321,020 As of December 31, 2022, we had $1,302.8 million of unrecognized share-based compensation expense, which we expect to recognize over a weighted-average period of 2.9 years. Fair value of stock options We measure stock options based on their estimated grant date fair values, which we determine using the Black-Scholes option-pricing model, and we record the resulting expense in our consolidated statements of operations over the requisite service period, which is generally four years. We estimated the fair value of the stock options granted during the year ended December 31, 2022, using the Black ‑ Scholes option-pricing model with the following assumptions: Year Ended Expected term (in years) 6.1 Risk-free interest rate 3.2 % Expected volatility 61.1 % Dividend yield — % The key inputs we used in the Black-Scholes model are: • Expected term – The expected term represents the period we expect our share-based awards to be outstanding, which is also the period we used to measure risk-free interest rates and expected volatility. We estimated the expected term using the simplified method as we do not have sufficient historical stock option exercise data. • Risk-free interest rate – We estimated the risk-free interest rate based on zero-coupon U.S. Treasury notes. • Expected volatility – We estimated expected volatility based on a combination of our historical volatility and that of comparable publicly-traded companies. • Dividend yield – We applied a dividend yield of zero because we have never paid or declared dividends, and we have no plan to do so in the foreseeable future.

Earnings Per Share [Abstract]
Net income (loss) per share	Net income (loss) per share We present net income (loss) per share using the two-class method required for multiple classes of common stock. Holders of our Class A and Class B common stock have identical rights except with respect to voting, conversion and transfer rights and therefore share equally in our net income or losses. We calculate basic net income (loss) per share by dividing net income (loss) by the weighted-average number of shares of common stock outstanding during the period. Diluted net income (loss) per share gives effect to all potential shares of common stock, including stock options, RSAs and RSUs to the extent these are dilutive. The calculation of diluted net income (loss) of Class A common stock assumes the conversion of our Class B common stock to Class A common stock, while the diluted net income (loss) of Class B common stock does not assume the conversion of those shares to Class A common stock. We calculated basic and diluted net income (loss) per share as follows (in thousands, except per share amounts): Year Ended December 31, 2022 2021 2020 Class A Class B Class A Class B Class A Class B Basic net income (loss) per share: Numerator: Net income (loss) $ (83,110) $ (12,937) $ 274,699 $ 41,739 $ (96,499) $ (31,824) Denominator: Basic weighted-average shares used in computing net income (loss) per share 576,061 89,671 555,608 84,422 448,392 147,872 Basic net income (loss) per share $ (0.14) $ (0.14) $ 0.49 $ 0.49 $ (0.22) $ (0.22) Diluted net income (loss) per share: Numerator: Net income (loss) $ (83,110) $ (12,937) $ 274,699 $ 41,739 $ (96,499) $ (31,824) Reallocation of net income as a result of conversion of Class B to Class A common stock — — 41,739 — — — Reallocation of net income to Class B common stock — — — (3,115) — — Diluted net income (loss) $ (83,110) $ (12,937) $ 316,438 $ 38,624 $ (96,499) $ (31,824) Denominator: Basic weighted-average shares used in computing net income (loss) per share 576,061 89,671 555,608 84,422 448,392 147,872 Conversion of Class B to Class A common stock — — 84,422 — — — Weighted average effect of dilutive potential common stock — — 51,621 — — — Diluted weighted-average shares used in computing net income (loss) per share 576,061 89,671 691,651 84,422 448,392 147,872 Diluted net income (loss) per share $ (0.14) $ (0.14) $ 0.46 $ 0.46 $ (0.22) $ (0.22) Basic net loss per share is the same as diluted net loss per share for the periods we reported net losses.

Income taxes	Income taxes The components of income (loss) before provision for income taxes are as follows (in thousands): Year Ended December 31, 2022 2021 2020 United States $ 29,108 $ 331,447 $ 49,973 Foreign (115,052) (10,476) (176,993) Income (loss) before provision for income taxes $ (85,944) $ 320,971 $ (127,020) Provision for income taxes consists of the following (in thousands): Year Ended December 31, 2022 2021 2020 Current: Federal $ 1,681 $ — $ — State 7,385 2,303 79 Foreign 4,381 2,957 691 Total current tax expense 13,447 5,260 770 Deferred: Federal (1,861) 6 654 State (356) 6 5 Foreign (1,127) (739) (126) Total deferred tax expense (benefit) (3,344) (727) 533 Provision for income taxes $ 10,103 $ 4,533 $ 1,303 The difference between income taxes computed at the statutory federal income tax rate and the provision for income taxes is attributable to the following (in thousands): Year Ended December 31, 2022 2021 2020 Tax at U.S. statutory rate $ (18,048) $ 67,404 $ (26,674) State income taxes, net of benefit 5,502 2,307 84 Foreign operations 26,985 4,448 37,716 Permanent book/tax differences 6,598 409 1,927 Legal settlement — — 2,290 Share-based compensation (20,663) (269,009) (303,245) Change in valuation allowance 62,048 278,761 352,410 Tax credits (52,319) (79,787) (63,205) Provision for income taxes $ 10,103 $ 4,533 $ 1,303 The primary difference between our effective tax rate and the federal statutory rate is the full valuation allowance we have established on our federal, state and foreign net operating losses and credits and for the year ended December 31, 2022 includes the effects of the capitalization and amortization of research and development expenses as required by the 2017 Tax Cuts and Jobs Act. Significant components of our deferred tax assets and liabilities are as follows (in thousands): December 31, 2022 2021 Deferred tax assets: Net operating loss carryforwards $ 900,200 $ 1,036,254 Research tax credits 473,248 401,219 Reserves, accruals, and other 31,502 29,641 Lease obligation 56,185 58,860 Share-based compensation 40,976 63,798 Research capitalization and amortization 208,373 — Total deferred tax assets 1,710,484 1,589,772 Less: valuation allowance (1,660,609) (1,539,889) Deferred tax assets, net of valuation allowance 49,875 49,883 Deferred tax liabilities: Depreciation and amortization (44,790) (47,952) Prepaid expenses (4,190) (2,036) Total deferred tax liabilities (48,980) (49,988) Deferred tax assets (liabilities) $ 895 $ (105) Due to our history of losses, we believe it is more likely than not that our U.S. and Irish deferred tax assets will not be realized as of December 31, 2022. Accordingly, we have established a full valuation allowance on our U.S. and Irish deferred tax assets. Our valuation allowance increased by $120.7 million during the year ended December 31, 2022, primarily due to U.S. federal and state tax credits and the effects of the capitalization and amortization of research and development expenses as required by the 2017 Tax Cuts and Job Act. Our valuation allowance increased by $363.0 million during the year ended December 31, 2021, primarily due to U.S. federal and state tax losses and credits incurred during the period. As of December 31, 2022, we had federal, California and other state net operating loss carryforwards of $3,636.5 million, $551.8 million and $1,501.5 million, respectively. Our federal carryforwards do not expire. If not utilized, our California and other state carryforwards will begin to expire in 2028 and 2026, respectively. Utilization of our net operating loss carryforwards may be subject to annual limitations due to the ownership change limitations provided by Section 382 of the Internal Revenue Code and similar state provisions. Our net operating loss carryforwards could expire before utilization if subject to annual limitations. As of December 31, 2022, we had $173.2 million and $5.6 million of Irish and Other Foreign net operating loss carryforwards, respectively that can be carried forward indefinitely. As of December 31, 2022, we had federal and California research and development credit carryforwards of $426.5 million and $319.3 million, respectively. If not utilized, our federal carryforwards will begin to expire in 2030. Our California carryforwards do not expire. Changes in gross unrecognized tax benefits were as follows (in thousands): Gross Unrecognized Tax Benefits Balance as of December 31, 2020 $ 140,160 Increases for tax positions of prior years 2,906 Increases for tax positions of current year 61,993 Balance as of December 31, 2021 $ 205,059 Increases for tax positions of prior years — Decreases for tax positions of prior years (3,347) Increases for tax positions of current year 38,226 Balance as of December 31, 2022 $ 239,938 Recognizing the $239.9 million of gross unrecognized tax benefits we had as of December 31, 2022 would affect our effective tax rate by $3.2 million. The remaining $236.7 million of gross unrecognized tax benefits would be offset by the reversal of related deferred tax assets, which are subject to a full valuation allowance. We do not expect our gross unrecognized tax benefits to change significantly within the next 12 months. We recognize interest and penalties related to uncertain tax positions in provision for income taxes. Accrued interest and penalties are not material as of December 31, 2022 and 2021. We are subject to taxation in the U.S. and various other state and foreign jurisdictions. As we have net operating loss carryforwards for U.S. federal and state jurisdictions, the statute of limitations is open for all tax years. For material foreign jurisdictions, the tax years open to examination include the years 2017 and forward. We are currently under examination of our U.S. consolidated federal income tax return by the Internal Revenue Service for 2018 and 2019. We believe that we have adequately reserved for any adjustments to the provision for income taxes or other tax items that may ultimately result from these examinations. We have not recognized deferred taxes for the difference between the financial reporting basis and the tax basis of our investment in our foreign subsidiaries because we have the ability and intent to maintain our investments for the foreseeable future. If we were to remit earnings as of December 31, 2022, the residual taxes would not be material.

Accounting Policies [Abstract]
Basis of presentation	Basis of presentation and consolidationWe prepared the accompanying consolidated financial statements in accordance with generally accepted accounting principles in the United States ("GAAP"). The consolidated financial statements include the accounts of Pinterest, Inc. and its wholly owned subsidiaries. We have eliminated all intercompany balances and transactions.
Consolidation	Basis of presentation and consolidationWe prepared the accompanying consolidated financial statements in accordance with generally accepted accounting principles in the United States ("GAAP"). The consolidated financial statements include the accounts of Pinterest, Inc. and its wholly owned subsidiaries. We have eliminated all intercompany balances and transactions.
Reclassifications	Reclassifications We have reclassified certain amounts in prior periods to conform with current presentation.
Use of estimates	Use of estimates Preparing our consolidated financial statements in conformity with GAAP requires us to make estimates and judgments that affect amounts reported in the consolidated financial statements and accompanying notes. We base these estimates and judgments on historical experience and various other assumptions that we consider reasonable. GAAP requires us to make estimates and assumptions in several areas, including the fair values of financial instruments, assets acquired and liabilities assumed through business combinations, share-based awards, and contingencies as well as the collectability of our accounts receivable, the useful lives of our intangible assets and property and equipment, the incremental borrowing rate we use to determine our operating lease liabilities, and revenue recognition, among others. Actual results could differ materially from these estimates and judgments.
Segments	SegmentsWe operate as a single operating segment. Our chief operating decision maker is our Chief Executive Officer ("CEO"), who reviews financial information presented on a consolidated basis, accompanied by disaggregated information about our revenue, for purposes of making operating decisions, assessing financial performance and allocating resources.
Revenue recognition and Cost of revenue	Revenue recognition We generate revenue by delivering ads on our website and mobile application. We recognize revenue only after transferring control of promised goods or services to customers, which occurs when a user clicks on an ad contracted on a CPC basis, views an ad contracted on a CPM basis or views a video ad contracted on a CPV basis. We typically bill customers on a CPC, CPM or CPV basis, and our payment terms vary by customer type and location. The term between billing and payment due dates is not significant. We recognize revenue only after satisfying our contractual performance obligations. We occasionally offer customers free ad inventory. When contracts with our customers contain multiple performance obligations, we allocate the overall transaction price, which is the amount of consideration to which we expect to be entitled in exchange for promised goods or services, to each of the distinct performance obligations based on their relative standalone selling prices. We generally determine standalone selling prices based on the effective price charged per contracted click, impression or view, and we do not disclose the value of unsatisfied performance obligations because the original expected duration of our contracts is generally less than one year. We record sales commissions in sales and marketing as incurred because we would amortize these over a period of less than one year. Cost of revenue Cost of revenue consists primarily of expenses associated with the delivery of our service, including the cost of hosting our website and mobile application. Cost of revenue also includes personnel-related expense, including salaries, benefits and share-based compensation for employees on our operations teams, payments associated with partner arrangements, credit card and other transaction processing fees, amortization of acquired intangible assets and allocated facilities and other supporting overhead costs.
Share-based compensation	Share-based compensation Restricted stock units ("RSUs") granted under our 2009 Stock Plan (the "2009 Plan") are subject to both a service condition, which is typically satisfied over four years, and a performance condition, which was deemed satisfied upon the pricing of our initial public offering ("IPO"). We did not record any share-based compensation expense for our RSUs prior to our IPO because the performance condition had not yet been satisfied. Upon pricing our IPO, we recorded cumulative share-based compensation expense using the accelerated attribution method for those RSUs granted under our 2009 Plan for which the service condition had been satisfied at that date. We record the remaining unrecognized share-based compensation expense over the remainder of the requisite service period. RSUs, restricted stock awards ("RSAs"), and stock options granted under our 2019 Omnibus Incentive Plan (the "2019 Plan") are subject only to a service condition, which is typically satisfied over four years. We record share-based compensation expense for these RSUs, RSAs and stock options on a straight-line basis over the requisite service period. We measure RSUs and RSAs based on the fair market value of our common stock on the grant date and stock options based on their estimated grant date fair values, which we determine using the Black-Scholes option-pricing model. We record the resulting expense in our consolidated statements of operations over the requisite service period, which is generally four years, and we account for forfeitures as they occur.
Income taxes	We account for income taxes using the asset and liability method. We recognize deferred tax assets and liabilities for temporary differences between the financial reporting and tax bases of assets and liabilities using the enacted statutory tax rates in effect for the years in which we expect the differences to reverse. We establish valuation allowances to reduce deferred tax assets to the amounts we believe it is more likely than not we will be able to realize. We recognize tax benefits from uncertain tax positions when we believe it is more likely than not that the tax position is sustainable on examination by tax authorities based on its technical merits. We recognize taxes on Global Intangible Low-Taxed Income as incurred.
Advertising expenses	Advertising expensesWe record advertising expenses as incurred and include these in sales and marketing in the consolidated statements of operations.
Marketable securities	Marketable securities We invest in highly liquid corporate debt securities, U.S. treasury securities, asset-backed securities, U.S. government agency securities, municipal securities, non-U.S. government and supranational bonds and certificates of deposit. We classify marketable investments with stated maturities of ninety days or less from the date of purchase as cash equivalents and those with stated maturities greater than ninety days from the date of purchase as marketable securities. We classify our marketable securities as available-for-sale investments in our current assets because they are available for use to support current operations. We carry our marketable investments at fair value and record unrealized gains or losses, net of taxes, in accumulated other comprehensive loss in stockholders’ equity. We determine realized gains and losses on the sale of marketable investments using a specific identification method and record these and any expected credit losses in interest expense and other income (expense), net.
Fair value measurements	Fair value measurements We account for certain assets and liabilities at fair value, which is the amount we believe market participants would be willing to receive to sell an asset or pay to transfer a liability in an orderly transaction. We categorize these assets and liabilities into the three levels below based on the degree to which the inputs we use to measure their fair values are observable in active markets. We use the most observable inputs available to us when measuring fair value. • Level 1: Observable inputs such as quoted prices for identical assets or liabilities in active markets • Level 2: Observable inputs such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical assets or liabilities in inactive markets, or inputs that are derived principally from or corroborated by observable market data or other means • Level 3: Unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities
Accounts receivable, net of allowances	Accounts receivable, net of allowances We record accounts receivable at the original invoiced amount. We maintain an allowance for credit losses for any receivables we may be unable to collect. We estimate uncollectible receivables based on our receivables’ age, our customers’ credit quality and current economic conditions, among other factors that may affect our customers’ ability to pay. We also maintain an allowance for sales credits, which we determine based on historical credits issued to customers. We include the allowances for credit losses and sales credits in accounts receivable, net in the consolidated balance sheets.
Property and equipment	We carry property and equipment at cost less accumulated depreciation and calculate depreciation using the straight-line method over our assets’ estimated useful lives, which are generally: Property and Equipment Useful Life Computer and network equipment 3 years Furniture and fixtures 4 years Leasehold improvements Lesser of estimated useful life or remaining lease term
Leases and operating lease incremental borrowing rate	Leases and operating lease incremental borrowing rate We lease office space under operating leases with expiration dates through 2033. We determine whether an arrangement constitutes a lease at inception and record lease liabilities and right-of-use assets on our consolidated balance sheets at lease commencement. We measure lease liabilities based on the present value of the total lease payments not yet paid discounted based on the more readily determinable of the rate implicit in the lease or our incremental borrowing rate, which is the estimated rate we would be required to pay for a collateralized borrowing equal to the total lease payments over the term of the lease. We estimate our incremental borrowing rate based on an analysis of publicly traded debt securities of companies with credit and financial profiles similar to our own. We measure right-of-use assets based on the corresponding lease liability adjusted for (i) payments made to the lessor at or before the commencement date, (ii) initial direct costs we incur and (iii) tenant incentives under the lease. We begin recognizing rent expense when the lessor makes the underlying asset available to us, we do not assume renewals or early terminations unless we are reasonably certain to exercise these options at commencement and we do not allocate consideration between lease and non-lease components. For short-term leases, we record rent expense in our consolidated statements of operations on a straight-line basis over the lease term and record variable lease payments as incurred.
Business combinations	Business combinations We include the results of operations of businesses that we acquire in our consolidated financial statements beginning on their respective acquisition dates. We allocate the fair value of the purchase consideration to the assets acquired and liabilities assumed based on their estimated fair values. When the fair value of the purchase consideration exceeds the fair values of the identifiable assets and liabilities acquired, we record the excess as goodwill. Our estimates of fair value are based on assumptions we believe to be reasonable but which are inherently uncertain and unpredictable, and as a result, actual results may differ from estimates. During the measurement period, which is one year from the acquisition date, we may record adjustments to the assets and liabilities acquired with the corresponding offset to goodwill. Any adjustments after the measurement period are reflected in our consolidated statements of operations.
Long-lived assets, including goodwill and intangible assets	Long-lived assets, including goodwill and intangible assets We record definite-lived intangible assets at fair value less accumulated amortization. We calculate amortization using the straight-line method over the assets’ estimated useful lives of up to ten years. We review our property and equipment and intangible assets for impairment whenever events or circumstances indicate that an asset’s carrying value may not be recoverable. We measure recoverability by comparing an asset’s carrying value to the future undiscounted cash flows that we expect it to generate. If this test indicates that the asset’s carrying value is not recoverable, we record an impairment charge to reduce the asset’s carrying value to its fair value. In the fourth quarter of 2022 we recorded $9.4 million of impairment charges for acquired intangible assets. We did not record any other material property and equipment or intangible asset impairments during the periods presented. We review goodwill for impairment at least annually or more frequently if current circumstances or events indicate that the fair value of our single reporting unit may be less than its carrying value. We did not record any goodwill impairment during the periods presented.
Website development costs	Website development costs We capitalize costs to develop our website and mobile application when preliminary development efforts are successfully completed, management has authorized and committed project funding, and it is probable that the project will be completed and the software will be used as intended. Due to the iterative process by which we perform upgrades and the relatively short duration of our development projects, development costs meeting our capitalization criteria were not material during the periods presented.
Loss contingencies	Loss contingencies We are involved in various lawsuits, claims and proceedings that arise in the ordinary course of business. We record a liability for these when we believe it is probable that we have incurred a loss and can reasonably estimate the loss. We regularly evaluate current information to determine whether we should adjust a recorded liability or record a new one.
Foreign currency	Foreign currency The functional currency of our international subsidiaries is generally their local currency. We translate these subsidiaries’ financial statements into U.S. dollars using month-end exchange rates for assets and liabilities and average exchange rates for revenue and costs and expenses. We record translation gains and losses in accumulated other comprehensive loss in stockholders’ equity. We record foreign exchange gains and losses in interest expense and other income (expense), net. Our net foreign exchange gains and losses were not material for the periods presented.
Concentration of business risk	Concentration of business risk We have an agreement with Amazon Web Services (“AWS”) to provide the cloud computing infrastructure we use to host our website, mobile application and many of the internal tools we use to operate our business. We are currently required to maintain a substantial majority of our monthly usage of certain compute, storage, data transfer and other services on AWS. Any transition of the cloud services currently provided by AWS to another cloud services provider would be difficult to implement and would cause us to incur significant time and expense.
Concentration of credit risk	Concentration of credit risk Financial instruments that may potentially expose us to concentrations of credit risk primarily consist of cash, cash equivalents, marketable securities and restricted cash. Our investment policy is meant to preserve capital and maintain liquidity. The policy limits our marketable investments to investment-grade securities and limits our credit exposure by limiting our concentration in any one corporate issuer or sector and by establishing a minimum credit rating for marketable investments we purchase. Although we deposit cash and marketable investments with multiple financial institutions, our deposits may exceed insurable limits.
Credit losses on accounts receivable	Our accounts receivable are generally unsecured. We monitor our customers’ credit quality on an ongoing basis and maintain reserves for estimated credit losses.
