NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1. Summary of Significant Accounting Policies

Basis of Presentation

We prepared the consolidated financial statements included herein pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with United States (U.S.) generally accepted accounting principles (GAAP) have been condensed or omitted pursuant to such rules and regulations. We believe that the disclosures are adequate to make the information presented not misleading. We recommend that these consolidated financial statements be read in conjunction with the audited consolidated financial statements and the notes thereto included in our latest annual report on Form 10-K for the fiscal year ended December 31, 2017, filed with the SEC on February 28, 2018.

In our opinion, these unaudited consolidated financial statements contain all adjustments (consisting only of normal recurring adjustments) considered necessary to present fairly our financial position as of March 31, 2018, our results of operations for the three months ended March 31, 2018, and our cash flows for the three months ended March 31, 2018. The results of operations for the interim period are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2018.

Basis of Consolidation

The consolidated financial statements include all the assets, liabilities, revenues, expenses and cash flows of entities in which we have a 100% voting control, which includes Stamps.com Inc., Auctane LLC (ShipStation), Interapptive, Inc. (ShipWorks), PSI Systems Inc. (Endicia), ShippingEasy Group, Inc. (ShippingEasy) and PhotoStamps Inc. In July 2016, we completed our acquisition of 100% of the outstanding shares of ShippingEasy. Please see Note 2 - “Acquisitions” in our Notes to Consolidated Financial Statements for further description.

Intercompany accounts and transactions between consolidated entities have been eliminated in consolidation.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates, judgments and assumptions that affect the amounts reported in the consolidated financial statements and the accompanying notes. Actual results could differ from those estimates, and such differences may be material to the consolidated financial statements. Significant estimates and judgments inherent in the preparation of the consolidated financial statements include estimates of loss contingencies and the realizability of deferred income taxes.

Business Combinations

The acquisition method of accounting is used for business combinations. The results of operations of acquired businesses are included in our consolidated financial statements prospectively from the date of acquisition. The fair value of purchase consideration is allocated to the assets acquired and liabilities assumed from the acquired entity and is generally based on their fair value at the acquisition date. The excess of the fair value of purchase consideration over the fair value of the assets acquired and liabilities assumed is recorded as goodwill. Historically, the primary items that have generated goodwill include anticipated synergies between the acquired business and the Company and the acquired assembled workforce, neither of which qualifies for recognition as an intangible asset. Acquisition-related expenses are recognized in our consolidated financial statements as incurred.

Contingencies and Litigation

In the ordinary course of business, we are subject to various routine litigation matters as a claimant and a defendant. We record any amounts recovered in these matters when received. We establish loss provisions for claims against us when the loss is both probable and can be reasonably estimated. If either or both of the criteria are not met, we assess whether there is at least a reasonable possibility that a loss, or additional losses, may have been incurred. If there is a reasonable possibility that a loss or additional loss may have been incurred for such proceedings, we disclose the estimate of the amount of loss or possible range of loss, or disclose that an estimate of loss cannot be made, as applicable.

Deferred Revenue

Our deferred revenue relates mainly to service revenue, which generally arises due to the timing of payment versus the provision of services for certain customers billed in advance. Approximately $2.1 million of revenue recognized in the three months ended March 31, 2018 was included in the deferred revenue balance at December 31, 2017.

Fair Value of Financial Instruments

Carrying amounts of certain of our financial instruments, including cash and cash equivalents, accounts receivable and accounts payable, approximate fair value due to their short maturities. The Company’s outstanding debt held by third-party financial institutions is carried at cost, adjusted for debt issuance costs. The Company’s debt is not publicly traded and the carrying amount typically approximates fair value for debt that accrues interest at a variable rate for companies with similar financial characteristics as the Company, which are considered Level 2 fair value inputs as defined in Note 8 in our Consolidated Financial Statements.

Goodwill and Indefinite-Lived Intangible Assets

Goodwill represents the excess of the fair value of consideration given over the fair value of the tangible assets, identifiable intangible assets and liabilities assumed in a business combination. We are required to test goodwill for impairment annually and whenever events or circumstances indicate the fair value of a reporting unit may be below its carrying value. A reporting unit is the operating segment or a business that is one level below that operating segment. Reporting units are aggregated as a single reporting unit if they have similar economic characteristics. We aggregated our reporting units into a single reporting unit because we determined they have similar economic characteristics.

Goodwill is reviewed for impairment annually on October 1 utilizing either a qualitative assessment or a two-step process. We have an option to make a qualitative assessment of a reporting unit's goodwill for impairment. If we choose to perform a qualitative assessment and determine the fair value more likely than not exceeds the carrying value, no further evaluation is necessary. When we perform the two-step process, the first step requires us to compare the fair value of our reporting unit, which we primarily determine using an income approach based on the present value of discounted cash flows, to the respective carrying value, which includes goodwill. If the fair value of our reporting unit exceeds its carrying value, the goodwill is not considered impaired. If the carrying value is higher than the fair value, there is an indication that impairment may exist and the second step is required. In step two, the implied fair value of goodwill is calculated as the excess of the fair value of our reporting unit over the fair values assigned to its assets and liabilities. If the implied fair value of goodwill is less than the carrying value of our reporting unit's goodwill, the difference is recognized as an impairment loss. As of March 31, 2018, we are not aware of any indicators of impairment that would require an impairment analysis other than our annual goodwill impairment analysis.

Indefinite-lived intangible assets are reviewed for impairment annually on October 1. In assessing other intangible assets not subject to amortization for impairment, the Company also has the option to perform a qualitative assessment to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of such an intangible asset is less than its carrying amount. If the Company determines that it is not more likely than not that the fair value of such an intangible asset is less than its carrying amount, then the Company is not required to perform any additional tests for assessing those intangible assets for impairment. However, if the Company concludes otherwise or elects not to perform the qualitative assessment, then it is required to perform a quantitative impairment test that involves a comparison of the estimated fair value of the intangible asset with its carrying value. If the carrying value of the intangible asset exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. As of March 31, 2018, we are not aware of any indicators of impairment that would require an impairment analysis other than our annual indefinite-lived intangible assets impairment analysis.

Long-Lived Assets and Finite-Lived Intangible Assets

Long-lived assets including intangible assets with finite useful lives are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.

We account for property and equipment at cost less accumulated depreciation and amortization. We compute depreciation using the straight-line method over the estimated useful life of the asset, generally three to five years for furniture, fixtures, and equipment and ten to forty years for building and building improvements. Leasehold improvements are capitalized and amortized over the shorter of the useful life of the asset or the remaining term of the lease. We have a policy of capitalizing expenditures that materially increase assets' useful lives and charging ordinary maintenance and repairs to operations as incurred. When property or equipment is disposed of, the cost and related accumulated depreciation and amortization are removed, and any gain or loss is included in income from operations.

Income Taxes

We account for income taxes in accordance with Financial Accounting Standards Board (FASB) ASC Topic No. 740, Income Taxes (Income Taxes), which requires that deferred tax assets and liabilities be recognized using enacted tax rates for the effect of temporary differences between the book and tax basis of recorded assets and liabilities. Income Taxes also requires that deferred tax assets be reduced by a valuation allowance if it is more likely than not that some or all of the net deferred tax assets will not be realized. We record a valuation allowance to reduce our gross deferred tax assets to the amount that is more likely than not (a likelihood of more than 50 percent) to be realized. In order for us to realize our deferred tax assets, we must be able to generate sufficient taxable income. We evaluate the appropriateness of our deferred tax assets and related valuation allowance in accordance with Income Taxes based on all available positive and negative evidence.

Revenue Recognition

We recognize revenues when we transfer control of promised goods or services to our customers in an amount that reflects the consideration to which we expect to be entitled to in exchange for those goods or services. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance, and collectability of consideration is probable. Our payment terms vary by the products and services offered. The term between billings and when payment is due is not significant.

Revenues are presented on a disaggregated basis on the consolidated statements of income.

Service revenues are recognized at a point in time, as transactions are processed, or over a period of time, typically one month or less. We earn service revenue from our mailing and shipping operations in several different ways: (1) customers may pay us a monthly fee based on a subscription plan which may be waived or refunded for certain customers; (2) we may be compensated directly by the United States Postal Service (USPS) for certain qualifying customers under our USPS partnership; (3) we may earn transaction related revenue based on customers purchasing postage or printing shipping labels; (4) we may earn compensation by offering customers a discounted postage rate that is provided to the customers by our integration partners; and (5) we may earn other types of revenue shares or other compensation from specific customers or integration partners.

Customers may purchase postage and other delivery services from the USPS and other carriers through our mailing and shipping solutions. When funds are transferred directly from customers to the carrier, these funds are not recognized as revenue. We also provide mailing and shipping services for which the cost of postage or delivery is included in the cost of the service and, therefore, is recognized as service revenue.

Product revenue consists of products sold through the mailing and shipping supplies stores which are available to our customers from within some of our mailing and shipping solutions. Products sold include shipping labels, mailing labels, dedicated postage printers, scales, and other mailing and shipping-focused office supplies. We recognize product revenue on product purchases upon delivery of the order to the customer.

(UNAUDITED)

We provide our customers with the opportunity to purchase parcel insurance directly through our solutions. Insurance revenue represents the gross amount charged to the customer for purchasing insurance and the related cost represents the amount paid to our insurance providers. We recognize insurance revenue on insurance purchases upon the ship date of the insured package.

Customized postage revenue, which includes the face value of postage, from the sale of PhotoStamps sheets and rolls is made pursuant to a sales contract that provides for transfer of both title and risk of loss upon our delivery to the carrier and revenue is recognized at that time.

On a limited basis, we allow third parties to offer products and promotions to our customer base. These arrangements generally provide payment in the form of a flat fee or revenue sharing arrangements where we receive payment upon customers accessing third party products and services. Total revenue from such advertising arrangements was not significant during the three months ended March 31, 2018 or 2017, respectively.

Short-Term Financing Obligations

We utilize short-term financing, which is separate from our debt, to fund certain Company operations. Short-term financing obligations are included in accounts payable and accrued expenses in the accompanying consolidated balance sheets. As of March 31, 2018, we had $16.3 million in short-term financing obligations and $89.2 million of unused credit. As of December 31, 2017, we had $17.2 million in short-term financing obligations and $103.4 million of unused credit.

Stock-Based Compensation

We account for share-based employee compensation plans under the fair value recognition and measurement provisions in accordance with applicable accounting standards, which require all share-based payments to employees, including grants of stock options and restricted stock units (RSUs), to be measured based on the grant date fair value of the awards, with the resulting expense generally recognized on a straight-line basis over the period during which the employee is required to perform service in exchange for the award.

We account for forfeitures as they occur. Prior to the adoption of ASU 2016-09, Compensation-Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, in 2017, share-based compensation expense was recorded net of estimated forfeitures, which were based on historical forfeitures and adjusted to reflect changes in facts and circumstances, if any.

We use the Black-Scholes-Merton option valuation model to estimate the fair value of share-based payment awards on the date of grant, which requires us to use a number of complex estimates and subjective assumptions, including stock price volatility, expected term, risk-free interest rates, and projected employee stock option exercise behaviors. In the case of options we grant, our assumption of expected volatility is based on the historical volatility of our stock price over the term equal to the expected life of the options. We base the risk-free interest rate on U.S. Treasury zero-coupon issues with a remaining term equal to the expected life of the options assumed at the date of grant. The estimated expected life represents the weighted average period the stock options are expected to remain outstanding, determined based on an analysis of historical exercise behavior.

Trademarks and Other Intangible Assets (excluding Goodwill)

Acquired trademarks and other intangibles (excluding goodwill) include both amortizable and non-amortizable assets and are included in intangible assets, net in the accompanying consolidated balance sheets. Intangible assets are carried at cost less accumulated amortization. Cost associated with internally developed intangible assets is typically expensed as incurred as research and development costs. Amortization of amortizable intangible assets is calculated on a straight-line basis, which is consistent with the expected future cash flows.

Treasury Stock

During the three-months ended March 31, 2018 and March 31, 2017, we repurchased approximately 120,000 shares and 356,000 shares for $23.2 million and $43.9 million, respectively. Also, during the three-months ended March 31, 2018 and March 31, 2017, we withheld 21,076 and 6,670 of shares, respectively, to satisfy income tax obligations related to performance-based inducement equity awards issued to the General Manager and Chief Technology Officer of ShippingEasy as described in Note 2 - “Acquisitions.”

Accounting Guidance Adopted in 2018

Definition of a Business

In January 2017, the FASB issued ASU 2017-01, guidance that changes the definition of a business for accounting purposes. Under the new guidance, an entity first determines whether substantially all of the fair value of a set of assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets. If this threshold is met, the set of assets is not deemed to be a business. If this threshold is not met, the entity then evaluates whether the set of assets meets the requirement to be deemed a business, which at minimum, requires there to be an input and a substantive process that together significantly contribute to the ability to create outputs. The guidance became effective on a prospective basis for the Company on January 1, 2018. The Company's adoption of the guidance on January 1, 2018 did not have a material impact on the Company’s consolidated financial statements.

Modification of Share-Based Payments

In May 2017, the FASB issued ASU 2017-09, guidance that clarifies when changes to the terms and conditions of share-based awards must be accounted for as modifications. The guidance does not change the accounting treatment for modifications. The guidance became effective for the Company on January 1, 2018 and was adopted on a prospective basis. The adoption of the guidance did not have a material impact on the Company’s consolidated financial statements.

Revenue Recognition

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, an updated standard on revenue recognition. This ASU superseded the revenue recognition requirements in Accounting Standards Codification Topic 605, Revenue Recognition, and most industry-specific guidance. ASU 2014-09 provides enhancements to the quality and consistency of how revenue is reported while also improving comparability in the financial statements of companies reporting using U.S. GAAP and International Financial Reporting Standards. The core principle of the new standard is for companies to recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the consideration to which the company expects to be entitled in exchange for those goods or services. In doing so, companies may be required to use more judgment and make more estimates than under current authoritative guidance.

During fiscal 2017, the FASB issued additional clarification guidance on the new revenue recognition standard which also included certain scope improvements and practical expedients. The new revenue recognition standard became effective for the Company on January 1, 2018 and could be applied retrospectively to each prior reporting period presented (full retrospective method) or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (modified retrospective method).

On January 1, 2018, the Company adopted the guidance under the modified retrospective method. The adoption of the guidance did not have a material impact on the Company's consolidated financial statements.

Accounting Guidance Not Yet Adopted

Goodwill Impairment

In January 2017, the FASB issued ASU 2017-04, a standard which simplifies the accounting for goodwill impairment. The guidance removes Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation. Goodwill impairment will now be the amount by which a reporting unit's carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The guidance will become effective on a prospective basis for the Company on January 1, 2020 and is not expected to have a material impact on the Company's consolidated financial statements.

Leases

In February 2016, the FASB issued ASU 2016-02, a new accounting standard for leases. The new standard generally requires the recognition of financing and operating lease liabilities and corresponding right-of-use assets on the balance sheet. For financing leases, a lessee recognizes amortization of the right-of-use asset as an operating expense over the lease term separately from interest on the lease liability. For operating leases, a lessee recognizes its total lease expense as an operating expense over the lease term. The amendments are effective for the Company in the first quarter of 2019 using a modified retrospective approach with early adoption permitted. The Company is currently evaluating the impact the adoption of this standard will have on its consolidated financial statements.

Subsequent Events

We are not aware of any material subsequent events or transactions that have occurred that would require recognition in the financial statements or disclosure in the notes to the financial statements.

2. Acquisitions

We have accounted for all of our acquisitions under the acquisition method of accounting in accordance with the provisions of FASB ASC Topic No. 805, Business Combinations.

ShippingEasy Acquisition

On July 1, 2016, we completed our acquisition of ShippingEasy Group, Inc. (ShippingEasy). The net purchase price including adjustments for net working capital totaled approximately $55.4 million and was funded from current cash and investment balances.

In connection with the acquisition, we issued performance-based inducement equity awards to each of the General Manager and Chief Technology Officer of ShippingEasy. These inducement awards cover an aggregate of up to 43,567 common shares each if earnings targets for ShippingEasy are achieved over a two and one-half year period which began July 1, 2016. The awards are subject to proration if at least 75% of the applicable target is achieved and are subject to forfeiture or acceleration based on changes in employment circumstances over the performance period.

In fiscal 2016, we determined the achievement of 100% of the earnings target for the six months ended December 31, 2016 was probable, therefore, we recognized approximately $1.9 million of stock-based compensation expense, representing 21,783 shares, for these inducement equity awards during the six months ended December 31, 2016. The equity award for the first phase was issued in the first quarter of 2017 with 15,113 shares distributed and 6,670 shares withheld to satisfy income tax obligations. In fiscal 2017, we determined the achievement of 100% of the earnings target for the twelve months ended December 31, 2017 was probable, therefore, we recognized approximately $4.9 million of stock-based compensation expense, representing 56,638 shares, for these inducement equity awards during the year ended December 31, 2017. The equity award for the second phase was issued in the first quarter of 2018 with 35,562 shares distributed and 21,076 shares withheld to satisfy income tax obligations. In the first quarter of 2018, we determined the achievement of 100% of the earnings target for the twelve months ended December 31, 2018 is probable, therefore, we recognized approximately $189,000 of stock-based compensation expense, representing 25% of the 8,713 shares that would be earned in the year ending December 31, 2018, for these inducement equity awards during the three months ended March 31, 2018.

We also issued inducement stock option grants for an aggregate of approximately 62,000 shares of Stamps.com common stock to 48 new employees in connection with our acquisition of ShippingEasy.

3. Commitments and Contingencies

Legal Proceedings

We are subject to various routine legal proceedings and claims incidental to our business, and we do not believe that these proceedings and claims would reasonably be expected to have a material adverse effect on our financial position, results of operations, or cash flows.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

On February 8, 2018, a putative class action complaint was filed against us in a case entitled Juan Lopez and Nicholas Dixon v. Stamps.com, Inc., Case No. 2:18-cv-01101, in the United States District Court for the Central District of California, Western Division, alleging wage and hour claims on behalf of our current and former “non-exempt” hourly call center employees. The complaint seeks class certification, unspecified damages, unpaid wages, penalties, restitution, interest, and attorneys’ fees and costs. We expect to defend this case vigorously. Due to the preliminary nature of the case, an estimate of the possible loss or range of loss, if any, cannot be determined.

The Company had not accrued any amounts related to any of the Company’s legal proceedings as of March 31, 2018 and December 31, 2017, respectively.

Although management at present believes that the ultimate outcome of the various routine proceedings, individually and in the aggregate, will not materially harm our financial position, results of operations, cash flows, or overall trends, legal proceedings are subject to inherent uncertainties, and unfavorable rulings or other events could occur. An unfavorable outcome for an amount in excess of management's present expectations may result in a material adverse impact on our business, results of operations, financial position, and overall trends.

Commitments

The Company leases facilities pursuant to noncancelable operating lease agreements expiring through 2021. Rent expense is recognized on a straight-line basis over the lease term. Lease incentives are amortized over the lease term on a straight-line basis. Leasehold improvements are capitalized and amortized over the shorter of the useful life of the asset or the remaining term of the lease. Rent expense for the three months ended March 31, 2018 was approximately $933,000. Rent expense for the three months ended March 31, 2017 was approximately $1.0 million.

We recorded amortization of intangible assets totaling approximately $4.0 million for each of the three months ended March 31, 2018 and 2017. Amortization of intangible assets is included in general and administrative expense in the accompanying consolidated statements of income.

Our estimated amortization expense for the next five years and thereafter is as follows (in thousands):

Total	$	65,592

7. Income Taxes

Our income tax expense for the three months ended March 31, 2018 and 2017 was $1.6 million and $660,000, respectively. The income tax expense for the three months ended March 31, 2018 was primarily due to our pre-tax income multiplied by an estimated annual effective tax rate and discrete tax benefits of approximately $10.7 million recorded during the quarter related to exercises of stock awards. The income tax expense for the three months ended March 31, 2017 was primarily due to our pre-tax income multiplied by an estimated annual effective tax rate and discrete tax benefits of approximately $12.6 million recorded during the quarter related to exercises of stock awards. Our income tax expense for the three months ended March 31, 2018 was higher than our income tax expense for the three months ended March 31, 2017 primarily due to higher pre-tax income and lower discrete tax benefits related to exercises of stock awards.

Our effective income tax rate differs from the statutory income tax rate primarily as a result of permanent tax adjustments for tax benefits from exercises of stock awards and research and development tax credits, as well as nondeductible items and state taxes. As of March 31, 2018 and December 31, 2017, we have recorded a valuation allowance of $490,000 and $410,000 against certain state research and development credits for which we believe it is more likely than not that these deferred tax assets will not be realized.

We recorded provisional amounts as of December 31, 2017 related to certain income tax effects of the Tax Cuts and Jobs Act

enacted December 22, 2017 under guidance set forth in Staff Accounting Bulletin No. 118 (SAB 118). These amounts have not been adjusted as of March 31, 2018, and we will continue to monitor any changes to the provisional amounts during the measurement period or until the accounting is complete. Any subsequent adjustment to the these amounts will be recorded to current tax expense in the quarters of 2018 when the analysis is complete.

8. Fair Value Measurements

Financial assets measured at fair value on a recurring basis are classified in one of the three categories described below:

Level 1 - Valuations based on unadjusted quoted prices for identical assets in an active market

Level 2 - Valuations based on quoted prices in markets where trading occurs infrequently or whose values are based on quoted prices of instruments with similar attributes in active markets

Level 3 - Valuations based on inputs that are unobservable and involve management judgment and our own assumptions about market participants and pricing

The following tables summarize our financial assets measured at fair value on a recurring basis as of March 31, 2018 and December 31, 2017 (in thousands):

We target larger enterprises that need a richer set of mailing capabilities such as multiple-user functionality, automated Certified Mail forms, additional reference codes and higher allowable postage balances. We target shippers such as e-commerce merchants, online retailers, fulfillment houses, warehouses, and large retailers that need shipping specific features such as direct integration into the customer's order databases, faster label printing speed, and the ability to customize and save shipping profiles.

We have arrangements with the USPS where we are compensated directly if a customer or integration partner prints certain classes and amounts of domestic or international USPS shipping labels. We may waive or refund our service fees for these or other customers. In addition, we also have service plans with lower monthly subscription fees which offer more limited functionality and are targeted at retaining customers who print a lower volume of postage. We offer service plans where customers are not charged a monthly fee but instead purchase labels for use as needed. We also offer high volume mailing products for an annual fee. We also earn compensation by offering customers a discounted postage rate that is provided to the customers by our integration partners, and we may earn other types of revenue share or other compensation from specific customers or partners.

We define "paid customers" for the quarter as ones from whom we successfully collected service fees or otherwise earned revenue at least once during that quarter, and we define average monthly revenue per paid customer (ARPU) as one-third of quarterly mailing and shipping revenue divided by paid customers. We define lost paid customers (Lost Paid Customers) as customers from whom we successfully collected service fees or otherwise earned revenue at least once during the previous quarter but not during the current quarter, less recaptured paid customers. We define monthly paid customer cancellation rate (Monthly Churn) as a fraction, the numerator of which is the quotient of Lost Paid Customers in a quarter divided by the sum of paid customers in the prior quarter and new paid customers in the current quarter, and the denominator of which is three months.

The following table sets forth the number of paid customers in the period for our mailing and shipping business (in thousands):



Year	First Quarter
2018	740
2017	722

The following table sets forth the growth in paid customers and average monthly revenue per paid customer for our mailing and shipping business (in thousands except average monthly revenue per paid customer and percentage):

Paid customers for the quarter	740		722		2.6	%
Average monthly revenue per paid customer	$	58.96	$	47.36	24.5	%
Mailing and shipping revenue	$	130,963	$	102,574	27.7	%

The increase in paid customers is primarily the result of increased sales and marketing spend and better performance in our marketing programs.

The increase in our average monthly revenue per paid customer was primarily the result of the growth in our shipping business where we have the ability to better monetize postage volume as compared to monthly flat rate subscription fees and growth in international service offerings to our domestic customers.

Customized postage	1.9		%	2.3		%
Other	0.0		%	0.0		%
Total revenue	100.0		%	100.0		%

Our revenue is derived primarily from five sources: (1) service and transaction related revenues from our USPS mailing and shipping services, our multi-carrier shipping services and our mailing and shipping integrations; (2) product revenue from the direct sale of consumables and supplies through our Supplies Stores; (3) package insurance revenue from our branded insurance offerings; (4) customized postage revenue from the sale of PhotoStamps postage labels; and (5) other revenue, consisting of advertising revenue derived from advertising programs with our existing customers.

We earn service revenue from our mailing and shipping operations in several different ways: (1) customers may pay us a monthly fee based on a subscription plan which may be waived or refunded for certain customers; (2) we may be compensated directly by the USPS for certain qualifying customers under our USPS partnership; (3) we may earn transaction related revenue based on customers purchasing postage or printing shipping labels; (4) we may earn compensation by offering customers a discounted postage rate that is provided to the customers by our integration partners; and (5) we may earn other types of revenue shares or other compensation from specific customers or integration partners.

Service revenue increased 31% to $120.9 million in the three months ended March 31, 2018 from $92.4 million in the three months ended March 31, 2017. The increase in service revenue during the three months ended March 31, 2018 consisted of a 28% increase in our average service revenue per paid customer (Service Revenue ARPU) and a 3% increase in the number of our average paid customers.

The increase in the number of our paid customers was attributable to the factors described in the previous section.

The increase in our Service Revenue ARPU was attributable to (1) the factors that resulted in an increase in the average total mailing and shipping revenue per paid customer described in the previous section and (2) the renewal of two of our agreements with the USPS with improved economics.

Product revenue was $5.7 million in both the three months ended March 31, 2018 and three months ended March 31, 2017. Product revenue is primarily driven by labels, such as NetStamps and DYMO Stamps, which are used for mailing. As our growth in postage has been driven more by shipping than mailing over the recent years, our product revenue has not kept pace with our growth in total revenue and is approximately flat year over year.

Table of Contents

Insurance revenue was $4.4 million in both the three months ended March 31, 2018 and three months ended March 31, 2017. Our insurance revenue was approximately flat year over year, despite the growth in service revenue, primarily due to the increase in high volume shipper customers. High volume shipper customers often self-insure, so while the high volume shipping business results in higher service fee revenue, it may not result in higher insurance revenue.

Customized postage revenue increased 6% to $2.6 million in the three months ended March 31, 2018 from $2.4 million in the three months ended March 31, 2017. The increase was primarily attributable to increases in high volume customer orders. High volume order sales are unpredictable and vary from quarter to quarter.

Cost of Revenue

The following table shows cost of revenues and cost of revenues as a percentage of associated revenue for the periods indicated (in thousands except percentage):



	Three Months Ended March 31,
	2018			2017
Cost of revenues
Service	20,649			12,676
Product	1,751			1,802
Insurance	998			1,368

Insurance	22.8		%	30.8		%
Customized postage	82.5		%	77.5		%
Total cost as a percentage of total revenues	19.1		%	16.9		%

Cost of service revenue principally consists of the cost of customer service, certain promotional expenses, system operating costs, credit card processing fees, vendor costs and expenses, and customer misprints that do not qualify for reimbursement from the USPS. Cost of product revenue principally consists of the cost of products sold through our Supplies Stores and the related costs of shipping and handling. The cost of insurance revenue principally consists of parcel insurance offering costs through our third party insurance providers. Cost of customized postage revenue principally consists of the face value of postage, customer service, image review costs, and printing and fulfillment costs.

Cost of service revenue increased 63% to $20.6 million in the three months ended March 31, 2018 from $12.7 million in the three months ended March 31, 2017. The increase during the three months ended March 31, 2018 was primarily attributable to (1) $5.3 million increase in vendor costs and expenses in connection with services for which we include such costs and expenses in revenue and cost of service and (2) higher credit card processing fees, which increased by $1.6 million, directly related to our higher revenue. Promotional expenses were not material in the three months ended March 31, 2018 and 2017.

Cost of service revenue as a percent of service revenue was 17% in the three months ended March 31, 2018 and 14% in the three months ended March 31, 2017. The increase is primarily attributable to the increase in vendor costs and expenses in connection with services for which we include such costs and expenses in revenue and cost of service.

Cost of product revenue was $1.8 million in both the three months ended March 31, 2018 and the three months ended March 31, 2017. Cost of product revenue as a percent of product revenue was 31% in the three months ended March 31, 2018 and 32% in the three months ended March 31, 2017.

Cost of insurance revenue decreased 27% to $1.0 million in the three months ended March 31, 2018 from $1.4 million in the three months ended March 31, 2017. The decrease was primarily attributable to lower cost as a result of a renegotiated contract.

Cost of insurance revenue as a percent of insurance revenue was 23% in the three months ended March 31, 2018 and 31% in the three months ended March 31, 2017. The decrease is due to the decreased costs of insurance revenue.

Table of Contents

Cost of customized postage revenue increased 13% to $2.1 million in the three months ended March 31, 2018 from $1.9 million in the three months ended March 31, 2017. The increase in cost of customized postage revenue during the three months ended March 31, 2018 is due to the increase in our customized postage volume.

Cost of customized postage revenue as a percent of customized postage revenue was 83% in the three months ended March 31, 2018 and 77% in the three months ended March 31, 2017. The increase was primarily the result of the increase in high volume orders which have a lower profit margin compared to website sales.

Operating Expenses

The following table outlines the components of our operating expense and their respective percentages of total revenues for the periods indicated (in thousands except percentage):



	Three Months Ended March 31,
	2018			2017
Operating expenses:
Sales and marketing	$	25,748		$	23,150
Research and development	12,073			10,522
General and administrative	21,016			18,982
Total operating expenses	$	58,837		$	52,654

Sales and marketing	19.3		%	22.0		%
Research and development	9.0		%	10.0		%
General and administrative	15.7		%	18.1		%
Total operating expenses as a percentage of total revenues	44.1		%	50.1		%

Sales and Marketing

Sales and marketing expense principally consists of spending to acquire new customers and compensation and related expenses for personnel engaged in sales, marketing, and business development activities. Our sales and marketing programs include direct sales, customer referral programs, customer re-marketing efforts, direct mail, online advertising, partnerships, telemarketing, and traditional advertising.

Sales and marketing expense increased 11% to $25.7 million in the three months ended March 31, 2018 from $23.2 million in the three months ended March 31, 2017. The increase during the three months ended March 31, 2018 was primarily attributable to an increase in discretionary marketing spend of $2.0 million and a net increase in headcount-related expenses including stock-based compensation of $0.4 million.

Sales and marketing expense as a percent of total revenue was 19% in the three months ended March 31, 2018 which was down compared to 22% in the three months ended March 31, 2017. The decline during the three months ended March 31, 2018 was primarily attributable to our ability to leverage our sales and marketing spend, which is expensed as incurred, relative to the year-over-year growth in our average monthly revenue per paid customer.

Research and Development

Research and development expense principally consists of compensation for personnel involved in the development of our services, depreciation of equipment and software, and expenditures for consulting services and third party software.

Research and development expense increased 15% to $12.1 million in the three months ended March 31, 2018 from $10.5 million in the three months ended March 31, 2017. The increase during the three months ended March 31, 2018 was primarily attributable to a net increase in headcount-related expense including stock-based compensation of $1.0 million. The increases in headcount-related expenses were incurred to support our expanded product offerings and technology infrastructure investments.

Table of Contents

Research and development expense as a percent of total revenue during the three months ended March 31, 2018 and 2017 was 9% and 10%, respectively.

General and Administrative

General and administrative expense principally consists of compensation and related costs for executive and administrative personnel; fees for legal and other professional services; depreciation of equipment, software, and building used for general corporate purposes; and amortization of intangible assets.

General and administrative expense increased 11% to $21.0 million in the three months ended March 31, 2018 from $19.0 million in the three months ended March 31, 2017. The increase during the three months ended March 31, 2018 was primarily attributable to an increase in indirect tax liabilities of $1.9 million.

General and administrative expense as a percent of total revenue was 16% in the three months ended March 31, 2018 and was 18% in the three months ended March 31, 2017. The decrease in general and administrative expense as a percent of total revenue in the three months ended March 31, 2018 is primarily due to economies of scale as we have grown as a result of our acquisitions.

Interest and Other Income

Interest and other income primarily consists of interest income from cash, cash equivalents, and short-term and long-term investments. Interest and other income increased to $49,000 in the three months ended March 31, 2018 from $30,000 in the three months ended March 31, 2017. The increase in interest and other income is primarily attributable to higher average cash balances in the three months ended March 31, 2018 compared to March 31, 2017.

Interest Expense

Interest expense consists of interest expense from the debt under our credit facility and the associated accretion of debt issuance costs. Interest expense was $590,000 in the three months ended March 31, 2018 compared to $880,000 in the three months ended March 31, 2017. The decrease in interest expense is primarily attributable to lower outstanding debt balances under our credit facility, partially offset by higher average interest rates in the three months ended March 31, 2018 compared to the three months ended March 31, 2017.

Provision for Income Taxes

Our income tax expense for the three months ended March 31, 2018 and 2017 was $1.6 million and $660,000, respectively. Our income tax expense for the three months ended March 31, 2018 was higher than our income tax expense for the three months ended March 31, 2017 primarily due to higher pre-tax income and lower discrete tax benefits related to exercises of stock awards.

See Note 7 — “Income Taxes” in our Notes to Consolidated Financial Statements for further discussion.

Liquidity and Capital Resources

As of March 31, 2018 and December 31, 2017, we had $195.8 million and $153.9 million, respectively, primarily in cash and cash equivalents.

Net cash provided by operating activities was approximately $55.3 million and $48.8 million during the three months ended March 31, 2018 and 2017, respectively. The increase in net cash provided by operating activities was primarily attributable to (1) the increase in net income of $13.9 million and (2) the increase in accounts payable and accrued expenses of $8.1 million, partially offset by (a) the increase in accounts receivable of $12.1 million and (b) the decrease in stock-based compensation expense of $3.8 million.

Table of Contents

Net cash used in investing activities was approximately $0.4 million and $3.1 million during the three months ended March 31, 2018 and 2017, respectively. The decrease in net cash used in investing activities was due to the prior period capital expenditures related to the build out of the Stamps.com headquarters.

Net cash used in financing activities was approximately $12.9 million and $35.7 million during the three months ended March 31, 2018 and 2017, respectively. The decrease in net cash used in financing activities was primarily due to the (1) $16.5 million decrease in stock repurchases and the (2) prior period optional repayment of debt of $10.0 million, partially offset by $4.1 million of current period payments of statutory income tax withholding obligations that were funded by shares withheld. The corresponding statutory income tax withholding obligations from the prior year of $0.8 million were accrued but not paid at March 31, 2017.

The following table is a schedule of our significant contractual obligations and commercial commitments (other than debt commitments) as of March 31, 2018 (in thousands):



Twelve Month Period Ending March 31,	Operating Lease Obligations
2019	$	2,889
2020	1,379
2021	1,407
2022	507
Thereafter	—
Total	$	6,182

On November 18, 2015, we entered into a Credit Agreement with a group of banks, which provided for a term loan of $82.5 million and a revolving credit facility with a maximum borrowing of $82.5 million. Our Credit Agreement matures on November 18, 2020. In connection with entering into the Credit Agreement, we incurred approximately $1.8 million in debt issuance costs which were recorded as debt discount and are being accreted as interest expense over the life of the Credit Agreement. Interest expense associated with the debt issuance costs for both the three months ended March 31, 2018 and 2017 was approximately $93,000. In December 2017, we repaid all of our revolving credit facility outstanding debt of $62.0 million.

Borrowings under the term loan are payable in quarterly installments which began on December 31, 2015. We pay interest on our Credit Agreement equal to the London Interbank Offered Rate plus an applicable margin, between 1.25% and 2.00%, based upon certain financial measures. As of March 31, 2018, our applicable margin was 1.25% and the interest rate on our outstanding loan was approximately 3.24%. We are subject to certain customary quarterly financial covenants under our Credit Agreement such as a maximum total leverage ratio and a minimum fixed charge coverage ratio. As of March 31, 2018, we were in compliance with the covenants of the Credit Agreement.

The Credit Agreement includes negative covenants, subject to exceptions, restricting or limiting our ability to among other things, incur additional indebtedness; grant liens; repurchase stock; pay dividends; and engage in certain investment, acquisition, and disposition transactions. The Credit Agreement imposes certain requirements in order for us to make dividend payments. As of March 31, 2018, such requirements were: (1) our Consolidated Total Leverage Ratio, as defined in the Credit Agreement, must be less than 2.75 to 1.00; (2) our Fixed Charge Coverage Ratio, as defined in the Credit Agreement, must be greater than 1.25 to 1.00; and (3) our Liquidity as defined in the Credit Agreement must be greater than $20 million. As of March 31, 2018, our Consolidated Total Leverage Ratio was 0.28 to 1.00, our Fixed Charge Coverage Ratio was 23.19 to 1.00 and our Liquidity was approximately $278 million, which includes cash and cash equivalent balances, as well as the available balance under the revolving credit facility. Based on our actual financial condition and results of operations, we do not believe that the provisions of the Credit Agreement currently represent a restriction to our ability to pay dividends in permissible amounts.

Business Outlook and Forward-Looking Statements

The following forward-looking statements are accompanied by, and should only be read in conjunction with, the qualifications and limitations described in the forward-looking statements discussion at the beginning of this Item 2 and the risks and other factors set forth in Item 1A "Risk Factors" of our Annual Report on Form 10-K for the year ended December 31, 2017 filed with the SEC on February 28, 2018.

We expect our mailing and shipping revenue to increase in 2018 compared to 2017. We expect our mailing and shipping revenue growth in 2018 to be less than the growth we achieved in 2017 now that we have passed the one year anniversary of our ShippingEasy acquisition. Our ability to grow our mailing and shipping revenue is partly dependent on our ability to increase our sales and marketing spend to acquire new customers and to retain our existing customers. To the extent we are not able to achieve our target increase in spending and acquire or retain customers, this would negatively impact our 2018 mailing and shipping revenue growth expectations.

We expect customized postage revenue to decline in 2018 compared to 2017, due to certain high volume business purchases occurring in 2017, which may not be repeated in 2018. High volume business orders for customized postage can fluctuate significantly from quarter to quarter and therefore historical trends may not be indicative of future results for customized postage revenue.

We expect our sales and marketing expense to increase in 2018 compared to 2017. We expect the percent increase in sales and marketing expense in 2018 to be greater than the percent increase in 2017 as we plan to increase our investments in headcount and non-headcount resources in 2018 to drive growth. We will continue to monitor our customer metrics and the state of the economy and adjust our level of spending accordingly. Sales and marketing spend is expensed in the period incurred, while the revenue and profits associated with the acquired customers are earned over the customers’ lifetimes. As a result, increased sales and marketing spend in future periods could result in a reduction in operating profit and cash flow compared to past periods.

We expect research and development expenses to be higher in 2018 as compared to 2017 as we expect to hire additional research and development personnel in 2018. We expect the percent increase in research and development expense in 2018 to be less than the percent increase in 2017.

We expect general and administrative expenses to be higher in 2018 as compared to 2017 as we expect to hire additional general and administrative personnel in 2018 and to continue to incur sales tax expense. We expect the percent increase in general and administrative expense in 2018 to be greater than the percent increase in 2017.

We expect our stock-based compensation expense to be lower in 2018 compared to 2017 due to smaller executive grants in 2018.

We expect our interest expense in 2018 to be lower than 2017 due to lower outstanding debt balances under our credit facility.

We expect our effective tax rate for 2018 to be higher than 2017 as we benefited from excess tax benefits related to the exercise of stock options in 2017 which we do not expect to recur at the same levels in 2018. However, there are other factors that impact taxable income compared to book income which can be difficult to predict and can change from quarter-to-quarter.

As discussed earlier in this Report, our expectations are subject to substantial uncertainty and our results are subject to macro-economic factors and other factors which could cause these trends to be worse than our current expectation or which could cause actual results to be materially different than our current expectations. These expectations are “forward looking statements,” are made only as of the date of this Report and are subject to the qualifications and limitations on forward-looking statements discussion in the beginning of Item 2 of this Report and the risks and other factors set forth in Item 1A “Risk Factors” of our Annual Report on Form 10-K for the year ended December 31, 2017, filed with the SEC on February 28, 2018. Our business has grown through acquisitions during 2014 through 2016; however the expectations above do not assume any future acquisitions or dispositions, any of which could have a significant impact on our current expectations. As described in our forward-looking statements discussion, we do not undertake any obligation to release publicly any revisions to our forward-looking statements to reflect events or circumstances after the date of this Report.

Critical Accounting Policies and Judgments

Management's discussion and analysis of our financial condition and results of operations is based on our unaudited financial statements. The preparation of these financial statements is based on the selection of accounting policies and the application of significant accounting estimates, some of which require management to make judgments, estimates, and assumptions that affect the amounts reported in the financial statements and notes. Except as noted below, for more information regarding our critical accounting estimates and policies, see Part II, Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations-Critical Accounting Policies and Judgments" of our Annual Report on Form 10-K for the year ended December 31, 2017, filed with the SEC on February 28, 2018.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOUSURES ABOUT MARKET RISK

On November 18, 2015, we entered into a Credit Agreement with a group of banks, which provided for a term loan of $82.5 million and a revolving credit facility with a maximum borrowing of $82.5 million. Our Credit Agreement matures on November 18, 2020. As of March 31, 2018, the debt outstanding under our Credit Agreement, gross of debt issuance costs, was $68.1 million. Borrowings under the term loan are payable in quarterly installments which began on December 31, 2015. We pay interest on our Credit Agreement at a rate equal to the London Interbank Offered Rate plus an applicable margin, which is between 1.25% and 2.00%, based upon certain financial measures. As of March 31, 2018, our applicable margin was 1.25% and the interest rate on our outstanding loan was approximately 3.24%. Interest expense would not be significantly affected by either a 10% increase or decrease in the rates of interest on our debt.

We have not used derivative financial instruments in our investment portfolio. None of the instruments in our investment portfolio are held for trading purposes. Our cash equivalents consist primarily of money market securities and had a weighted average maturity of 27 days and a weighted average interest rate of 1.4% at March 31, 2018. The aggregate value of our cash and cash equivalents was $195.8 million at March 31, 2018. Interest rate fluctuations impact the carrying value of the portfolio. The fair value of our portfolio of marketable securities would not be significantly affected by either a 10% increase or decrease in the rates of interest due primarily to the short-term nature of the portfolio. We do not believe that the future market risks related to the above securities will have a material adverse impact on our financial position, results of operations, or liquidity.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act).

As of the end of the period covered by this Report, our management evaluated, with the participation of our Principal Executive Officer and Principal Financial Officer, the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Report. Based on that evaluation, our Principal Executive Officer and Principal Financial Officer have concluded, as of that time, that our disclosure controls and procedures were effective.

Changes in internal controls

During the quarter ended March 31, 2018, there has been no change in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

On October 24, 2017, the Board of Directors approved a new stock repurchase plan, which became effective November 10, 2017, that replaced our prior stock repurchase plan and authorized the Company to repurchase up to $90 million of stock over the six months following its effective date. On April 25, 2018, the Board of Directors approved a new share repurchase plan that will take effect upon expiration of the current plan on May 11, 2018 and authorizes the Company to repurchase up to $90 million of stock over the six months following its effective date.
