j2 Global Reports Fourth Quarter and Year End 2017 Results and Provides 2018 Outlook

Achieves Record Annual Revenues

Provides Fiscal 2018 Financial Estimates

Announces Twenty-Sixth Consecutive Quarterly Dividend Increase

LOS ANGELES -- j2 Global, Inc. (NASDAQ: JCOM) today reported financial results for the fourth quarter and year ended December 31, 2017, provided fiscal 2018 financial estimates and announced that its Board of Directors has declared an increased quarterly cash dividend of $0.405 per share.

"j2 continues to demonstrate its power as a vertically-driven, Internet information and services company," said Vivek Shah, CEO of j2 Global. "We have an expanding portfolio of some of the best ad- and subscription-supported brands on the Internet. We remain committed to the strategy and operating model that produced record results last year and should help us achieve our goals in 2018."

FOURTH QUARTER 2017 RESULTS

Q4 2017 quarterly revenues increased 25.7% to a Q4 record of $316.4 million compared to $251.8 million for Q4 2016.

Net cash provided by operating activities decreased 4.9% to $85.4 million compared to $89.8 million for Q4 2016. Q4 2017 free cash flow⁽¹⁾ decreased 8.9% to $75.3 million compared to $82.7 million for Q4 2016. The decline in free cash flow⁽¹⁾ is due to a greater percentage of the revenues and EBITDA coming from the media business which has a longer collection cycle resulting in less cash inflows associated with accounts receivable of approximately $19.0 million in comparison to Q4 2016.

GAAP earnings per diluted share⁽²⁾ increased 14.6% to $1.02 in Q4 2017 compared to $0.89 for Q4 2016. Adjusted non-GAAP earnings per diluted share⁽²⁾⁽³⁾ for the quarter increased 20.1% to $1.79 compared to $1.49 for Q4 2016.

GAAP net income increased 15.5% to $49.9 million in Q4 2017 compared to $43.2 million for Q4 2016.

Quarterly Adjusted EBITDA⁽⁴⁾ increased 21.8% to $141.9 million in the quarter compared to $116.5 million for Q4 2016.

j2 ended the quarter with approximately $408.7 million in cash and investments after deploying approximately $149.4 million during the quarter for acquisitions and the payment of j2's regular quarterly dividends.

Key financial results for Q4 2017 versus Q4 2016 are set forth in the following table (in millions, except per share amounts). Reconciliations of Adjusted non-GAAP earnings per diluted share, Adjusted EBITDA and free cash flow to their nearest comparable GAAP financial measures are attached to this Press Release.

FULL YEAR 2017 RESULTS

2017 revenues increased 27.9% to a record of $1,117.8 million in 2017 compared to $874.3 million for 2016.

Net cash provided by operating activities decreased 6.4% to $264.4 million in 2017 compared to $282.4 million for 2016. 2017 free cash flow⁽¹⁾ decreased 1.2% to $264.8 million compared to $267.9 million for 2016. The decline in free cash flow⁽¹⁾ is due to additional cash outflows associated with income taxes of approximately $28.0 million and a greater percentage of the revenues and EBITDA coming from the media business which has a longer collection cycle resulting in less cash inflows associated with accounts receivable of approximately $7.0 million in comparison to 2016.

GAAP earnings per diluted share⁽⁵⁾ decreased 9.6% to $2.83 in 2017 compared to $3.13 for 2016. The decrease over the prior comparable period is primarily attributed to the increase in interest expense associated with the issuance of the $650 million 6.0% Senior Notes due in 2025, the loss on extinguishment of the $250 million 8.0% Senior Notes and the increased amortization expense associated with acquisitions, most notably Everyday Health. Adjusted non-GAAP earnings per diluted share⁽⁵⁾⁽⁶⁾ for the year increased 13.0% to $5.64 compared to $4.99 for 2016.

GAAP net income decreased by 8.5% to $139.4 million in 2017 compared to $152.4 million for 2016. The decrease over the prior comparable period is primarily attributed to the increase in interest expense associated with the issuance of the $650 million 6.0% Senior Notes due in 2025, the loss on extinguishment of the $250 million 8.0% Senior Notes and the increased amortization expense associated with acquisitions, most notably Everyday Health.

Annual Adjusted EBITDA⁽⁴⁾ increased 16.9% to $463.0 million in 2017 compared to $396.1 million for 2016.

j2 ended the year with approximately $408.7 million in cash and investments after deploying approximately $256.1 million during the year for acquisitions and the payment of j2's regular quarterly dividends.

Key financial results for 2017 versus 2016 are set forth in the following table (in millions, except per share amounts). Reconciliations of Adjusted non-GAAP earnings per diluted share, Adjusted EBITDA and free cash flow to their nearest comparable GAAP financial measures are attached to this Press Release.

BUSINESS OUTLOOK

For fiscal 2018, the Company estimates that it will achieve revenues between $1.20 billion and $1.25 billion, Adjusted EBITDA between $480 million and $505 million and Adjusted non-GAAP earnings per diluted share of between $5.95 and $6.25.

Adjusted non-GAAP earnings per diluted share for 2018 excludes share-based compensation of between $31 million and $34 million, amortization of acquired intangibles and the impact of any currently unanticipated items, in each case net of tax.

It is anticipated that the non-GAAP effective tax rate for 2018 (exclusive of the release of reserves for uncertain tax positions) will be between 23.0% and 25.0%.

The Company has not reconciled the Adjusted non-GAAP earnings per diluted share and tax rate guidance included in this release to the most directly comparable GAAP measure because this cannot be done without unreasonable effort due to the variability with respect to costs related to acquisitions and taxation, which are potential adjustments to future earnings. We expect the variability of these items to have a potentially unpredictable and significant impact on our future GAAP financial results.

DIVIDEND

j2's Board of Directors approved a quarterly cash dividend of $0.405 per common share, a $0.01, or 2.5% increase versus last quarter's dividend. This is j2's twenty-sixth consecutive quarterly dividend increase since its first quarterly dividend in September 2011. The dividend will be paid on March 9, 2018 to all shareholders of record as of the close of business on February 22, 2018. Future dividends will be subject to Board approval.

EXTENSION OF SHARE REPURCHASE PROGRAM

The Company has extended its one-year five million share repurchase program set to expire February 19, 2018 by an additional year. Approximately 1.9 million shares remain available for purchase under the program.

About non-GAAP Financial Measures

To supplement our consolidated financial statements, which are prepared and presented in accordance with generally accepted accounting principles ("GAAP"), we use the following Adjusted non-GAAP financial measures: Adjusted non-GAAP net income, Adjusted non-GAAP earnings per diluted share, Adjusted EBITDA and free cash flow. The presentation of this financial information is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP.

We use these Adjusted non-GAAP financial measures for financial and operational decision-making and as a means to evaluate period-to-period comparisons. Our management believes that these Adjusted non-GAAP financial measures provide meaningful supplemental information regarding our performance and liquidity by excluding certain expenses and expenditures that may not be indicative of our recurring core business operating results. We believe that both management and investors benefit from referring to these Adjusted non-GAAP financial measures in assessing our performance and when planning, forecasting, and analyzing future periods. These Adjusted non-GAAP financial measures also facilitate management's internal comparisons to our historical performance and liquidity. We believe these Adjusted non-GAAP financial measures are useful to investors both because (1) they allow for greater transparency with respect to key metrics used by management in its financial and operational decision-making and (2) they are used by our institutional investors and the analyst community to help them analyze the health of our business.

For more information on these Adjusted non-GAAP financial measures, please see the appropriate GAAP to Adjusted non-GAAP reconciliation tables included within the attached Exhibit to this release.

Non-GAAP Financial Measures

To supplement its condensed consolidated financial statements, which are prepared and presented in accordance with US GAAP, the Company uses the following Non-GAAP financial measures: Adjusted EBITDA, Adjusted non-GAAP net income, and Adjusted non-GAAP diluted EPS (collectively the "Non-GAAP financial measures"). The presentation of this financial information is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with U.S. GAAP. The Company uses these Non-GAAP financial measures for financial and operational decision making and as a means to evaluate period-to-period comparisons. The Company believes that they provide useful information about core operating results, enhance the overall understanding of past financial performance and future prospects, and allow for greater transparency with respect to key metrics used by management in its financial and operational decision making.

(1) Share Based Compensation. The Company excludes stock-based compensation because it is non-cash in nature and because the Company believes that the Non-GAAP financial measures excluding this item provide meaningful supplemental information regarding operational performance. The Company further believes this measure is useful to investors in that it allows for greater transparency to certain line items in its financial statements. In addition, excluding this item from the Non-GAAP measures facilitates comparisons to historical operating results and comparisons to peers, many of which similarly exclude this item.

(2) Acquisition Related Integration Costs. The Company excludes certain acquisition and related integration costs such as severance, lease terminations, retention bonuses and other acquisition-specific items. The Company believes that the Non-GAAP financial measures excluding this item provide meaningful supplemental information regarding operational performance. In addition, excluding this item from the Non-GAAP measures facilitates comparisons to historical operating results and comparisons to peers, many of which similarly exclude this item.

(3) Interest Costs. In June 2014, the Company issued $402.5 million aggregate principal amount of 3.25% convertible senior notes. In accordance with GAAP, the Company separately accounts for the value of the liability and equity features of its outstanding convertible senior notes in a manner that reflects the Company's non-convertible debt borrowing rate. The value of the conversion feature, reflected as a debt discount, is amortized to interest expense over time. Accordingly, the Company recognizes imputed interest expense on its convertible senior notes of approximately 5.8% in its income statement. The Company excludes the difference between the imputed interest expense and the coupon interest expense of 3.25% because it is non-cash in nature and because the Company believes that the Non-GAAP financial measures excluding this item provide meaningful supplemental information regarding core operational performance. In addition, the Company has excluded 3 days of overlapping interest expense in June and the month of July in connection with the 8.0% senior unsecured notes and deferred issuance costs associated with the repayment of the line of credit. The Company has determined excluding these items from the Non-GAAP measures facilitates comparisons to historical operating results and comparisons to peers, many of which similarly exclude this item.

(4) Amortization. The Company excludes amortization of patents and acquired intangible assets because it is non-cash in nature and because the Company believes that the Non-GAAP financial measures excluding this item provide meaningful supplemental information regarding operational performance. In addition, excluding this item from the Non-GAAP measures facilitates comparisons to historical operating results and comparisons to peers, many of which similarly exclude this item.

(5) Tax Expense/Benefit from Prior Years. The Company excludes certain income tax-related items in respect of income tax audit settlements and their related FIN 48 accrual reversals. The Company believes that the Non-GAAP financial measures excluding this item provide meaningful supplemental information regarding operational performance. In addition, excluding this item from the Non-GAAP measures facilitates comparisons to historical operating results.

(6) Gain on Sale of Investment. The Company excludes the gain on sale of its strategic equity investment in Carbonite, Inc. The Company believes that the Non-GAAP financial measures excluding this item provide meaningful supplemental information regarding operational performance. In addition, excluding this item from the Non-GAAP measures facilitates comparisons to historical operating results.

(7) Gain on Sale of Businesses. The Company excludes the gain on sale of its businesses of Cambridge BioMarketing LLC, Web24, and Tea Leaves Health, LLC. The Company believes that the Non-GAAP financial measures excluding this item provide meaningful supplemental information regarding operational performance. In addition, excluding this item from the Non-GAAP measures facilitates comparisons to historical operating results.

(8) Tax Expense due to the Tax Cuts and Jobs Act. The Company excludes certain income tax-related items in respect of the Tax Cuts and Jobs Act, specifically, the non-current tax associated with the repatriation of untaxed foreign earnings, the revaluation of deferred tax liabilities and the revaluation for uncertain tax positions from prior years. The Company believes that the Non-GAAP financial measures excluding this item provide meaningful supplemental information regarding operational performance. In addition, excluding this item from the Non-GAAP measures facilitates comparisons to historical operating results.

(9) Convertible Debt Dilution. The Company excludes convertible debt dilution from diluted EPS. The Company believes that the Non-GAAP financial measures excluding this item provide meaningful supplemental information regarding operational performance. In addition, excluding this item from the Non-GAAP measures facilitates comparisons to historical operating results.

The Company presents Adjusted non-GAAP Cost of Revenues, Adjusted non-GAAP Research, Development and Engineering, Adjusted non-GAAP Sales and Marketing, Adjusted non-GAAP General and Administrative, Adjusted non-GAAP Interest Expense, Adjusted non-GAAP Other Income, Adjusted non-GAAP Income Tax Provision and Adjusted non-GAAP Net Income because the Company believes that these provide useful information about our operating results and enhance the overall understanding of past financial performance and future prospects.

Indirect tax expense (benefit) from prior years		1,970			(1,900	)		4,977			(1,000	)

Adjusted EBITDA	$	141,880		$	116,459		$	462,952		$	396,089

Adjusted EBITDA as calculated above represents earnings before interest and other expense, net, income tax expense, depreciation and amortization and the items used to reconcile GAAP to Adjusted non-GAAP financial measures, including (1) share-based compensation, (2) certain acquisition-related integration costs, (3) additional indirect tax expense from prior years and (4) certain gains on sale of businesses. We disclose Adjusted EBITDA as a supplemental Non-GAAP financial performance measure as we believe it is a useful metric by which to compare the performance of our business from period to period. We understand that measures similar to Adjusted EBITDA are broadly used by analysts, rating agencies and investors in assessing our performance. Accordingly, we believe that the presentation of Adjusted EBITDA provides useful information to investors.

Adjusted EBITDA is not in accordance with, or an alternative to, net income, and may be different from Non-GAAP measures used by other companies. In addition, Adjusted EBITDA is not based on any comprehensive set of accounting rules or principles. This Adjusted non-GAAP measure has limitations in that it does not reflect all of the amounts associated with the Company's results of operations determined in accordance with GAAP.
