First Quarter 2014 Results Summary

Gross Bookings and Revenue

• Gross bookings was $641 million for the first quarter of 2014, an increase of $422 million or 193% compared to the first quarter of 2013, and an increase of $9 million or 1% compared to the fourth quarter of 2013. In the first quarter of 2014, 75% of gross bookings were derived from our mobile audience.

• Revenue was $607 million for the first quarter of 2014, an increase of $401 million or 195% compared to the first quarter of 2013, and an increase of $5 million or 1% compared to the fourth quarter of 2013.

• The increases in both gross bookings and revenue from fourth quarter 2013 to first quarter 2014 were primarily due to higher gross bookings from Farm Heroes Saga following its mobile launch in January 2014. This increase was partially offset by a decrease in gross bookings from Candy Crush Saga, which accounted for 67% of first quarter 2014 gross bookings, down from 78% in the fourth quarter of 2013.

Adjusted EBITDA

• Adjusted EBITDA was $249 million for the first quarter of 2014, an increase of $167 million or 205% compared to the first quarter of 2013

• First quarter 2014 adjusted EBITDA decreased $20 million or 8% compared to the fourth quarter of 2013 primarily due to planned increases in marketing spend in conjunction with the launch of Farm Heroes Saga on mobile during the period, as well as increased investments in headcount.

Profit

• Profit was $127 million for the first quarter of 2014, an increase of $75 million or 142% compared to the first quarter of 2013

• First quarter 2014 profit decreased $32 million or 20% compared to the fourth quarter of 2013 primarily due to increases in marketing spend related to the launch of Farm Heroes Saga, share-based and other equity-related compensation expense of $78 million in the first quarter of 2014 as compared to $60 million in the fourth quarter of 2013, headcount additions, and unrealized foreign exchange losses, which were partially offset by lower tax expense.

Network Reach

• Daily Active Users (DAUs) increased to 143 million in the first quarter of 2014, up 107 million or 297% from first quarter 2013, and up 19 million or 15% from fourth quarter 2013.

• Monthly Active Users (MAUs) increased to 481 million in the first quarter of 2014, up 343 million or 249% from first quarter 2013, and up 73 million or 18% from fourth quarter 2013.

• We believe the increases in DAUs and MAUs reflect the continued growth of our player network coupled with a greater number of games being installed and played by our existing player base. We believe this increased activity is due to our introduction of additional games and our releases of new content on existing games, as well as our geographic expansion and the overall growth in consumer usage of mobile devices.

• Monthly Unique Users (MUUs) increased to 352 million in the first quarter of 2014, up 251 million or 249% from first quarter 2013, and up 48 million or 16% from fourth quarter 2013. We believe the increase in MUUs is driven by organic growth plus targeted acquisition efforts outside our traditional markets in North America and Western Europe.

Monetization

• Monthly Gross Average Bookings per Paying User (MGABPPU) increased to $18.02 in the first quarter of 2014, up $2.10 or 13% from first quarter 2013, and up $0.70 or 4% from fourth quarter 2013. We believe the increase in MGABPPU reflects our ability to retain our more engaged customers within our network through the consistent release of new content in existing games. Additionally, we believe that an increase in our payers who play in more than one game as well as the introduction of virtual currency in some of our games, which creates the opportunity to transact at higher amounts, had a positive impact on our MGABPPU during the period.

• Monthly Unique Payers (MUPs) in the first quarter of 2014 were 11.9 million, up 190% compared to 4.1 million in the first quarter of 2013. We believe this increase was driven by the growth in our MAUs and our MUUs as well as improved in-game monetization. First quarter 2014 MUPs declined compared to 12.2 million in the fourth quarter of 2013. We believe this decrease is primarily a result of reduced payment activity among the occasional payers on the network, in addition to the introduction of virtual currency in some of our games.

Forward Looking Statements

All statements other than statements of historical fact contained in this release, including statements regarding future growth and success of games and results of the operations of King Digital Entertainment plc are forward-looking statements. King has based these forward-looking statements on its estimates and assumptions as of the date of this release. These forward-looking statements are subject to a number of risks, uncertainties and assumptions that could cause actual results to differ materially. Factors that might cause or contribute to such differences include, but are not limited to: the fact that a relatively small number of games continue to account for a substantial majority of our revenue and gross bookings, and declines in popularity of these games could harm our financial results; our ability to develop new games and enhance existing games in a timely manner; market acceptance of new games and enhancements to existing games; intense competition in our industry; our reliance on the casual game format; our relatively short operating history in the mobile market; our dependence on the continued popularity of mobile games and devices; revenues and gross bookings from new games may not be sufficient to offset declines in revenues and gross bookings in more mature games; we may experience fluctuations in our quarterly operating results and other key metrics; we rely on various third-party platforms which may not retain their popularity; the need to attract and retain additional personnel; general economic conditions and their impact on consumer spending; the continued effectiveness of our marketing programs; as well as those risks detailed from time to time under the caption “Risk Factors” and elsewhere in King’s Securities and Exchange Commission filings and reports, including in the final prospectus filed pursuant to Rule 424(b) by the Company on March 27, 2014 and future filings and reports by the Company. In addition, King operates in a very competitive and rapidly changing environment. New risks emerge from time to time. It is not possible for King management to predict all risks, nor can King assess the impact of all factors on its business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements that King may make. In light of these risks, uncertainties and assumptions, the forward-looking events and circumstances discussed in this release are inherently uncertain and may not occur, and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements. Accordingly, you should not rely upon forward-looking statements as predictions of future events. King does not undertake any obligation to update publicly or revise any forward-looking statements for any reason after the date of this release, to conform these statements to actual results, future events, or to changes in King’s expectations.

Non-GAAP Financial Measures

King uses International Financial Reporting Standards (“IFRS”). In addition to IFRS financials, this release includes certain financial measures not based on IFRS, including gross bookings, adjusted revenue, adjusted EBITDA, adjusted EBITDA margin, capital expenditures, adjusted profit and adjusted EPS. These non-GAAP measures are in addition to, not a substitute for or superior to, measures of financial performance prepared in accordance with IFRS. The non-GAAP financial measures used by King may differ from the non-GAAP financial measures used by other companies, and is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with IFRS. Some limitations of the non-GAAP financial measures we use are listed below:

Gross Bookings: Gross bookings is a non-GAAP financial measure that is not calculated in accordance with IFRS. Gross bookings is equal to the total amount paid by our users for virtual items and for access to skill tournaments.

The Company uses gross bookings to evaluate the results of our operations, generate future operating plans and assess our performance. While King believes that this non-GAAP financial measure provides a meaningful measurement of our business performance during a particular period because it measures the total cash spend by our players in the period, this information should be considered as supplemental in nature and is not meant as a substitute for revenue recognized in accordance with IFRS. In addition, other companies, including companies within our industry, may calculate gross bookings differently or not at all, which reduces its usefulness as a comparative measure.

Adjusted Revenue: Adjusted revenue is a non-GAAP financial measure that is not calculated in accordance with IFRS. King defines adjusted revenue as revenue adjusted for changes in deferred revenue. King believes that adjusted revenue is a useful metric for calculating adjusted EBITDA margin and understanding our operating results and ongoing profitability.

4

Adjusted EBITDA and Adjusted EBITDA Margin: Adjusted EBITDA and adjusted EBITDA margin are non-GAAP financial measures that are not calculated in accordance with IFRS. King defines adjusted EBITDA as profit (loss), adjusted for income tax expense, other (income) expense, net finance (income) costs, depreciation, amortization, share-based and other equity-related compensation (including social security tax charges associated therewith) and changes in deferred revenue. King defines adjusted EBITDA margin as adjusted EBITDA as a percentage of adjusted revenue. King believes that adjusted EBITDA and adjusted EBITDA margin are useful metrics for investors to understand and evaluate our operating results and ongoing profitability because it permits investors to evaluate our recurring profitability from our ongoing operating activities. King also uses these measures internally to establish forecasts, budgets and operational goals and to manage and monitor our business, as well as evaluating our ongoing and historical performance. Adjusted EBITDA and adjusted EBITDA margin have certain limitations as analytical tools, and you should not consider them in isolation or as a substitute for analysis of our results of operations as reported under IFRS. Other companies, including companies in our industry, may calculate adjusted EBITDA differently or not at all, limiting its usefulness as a direct comparative measure.

Capital Expenditures: Capital expenditures is a non-GAAP financial measure that is not calculated in accordance with IFRS. King defines capital expenditures as the amount paid in the period for the purchase of property, plant and equipment, and intangible assets. King monitors capital expenditures as a measure of the amount we have invested in maintaining or growing the scope our business. Other companies, including companies in our industry, may calculate capital expenditures differently or not at all, limiting its usefulness as a direct comparative measure.

Adjusted Profit: Adjusted profit is a non-GAAP financial measure that is not calculated in accordance with IFRS. King defines adjusted profit as profit (loss), adjusted for share-based and other equity-related compensation (including social security tax charges associated therewith), changes in deferred revenue and amortization of acquired intangible assets. Other companies, including companies in our industry, may calculate adjusted profit differently or not at all, limiting its usefulness as a direct comparative measure.

Adjusted EPS: Adjusted EPS is a non-GAAP financial measure that is not calculated in accordance with IFRS. King defines adjusted EPS as adjusted profit divided by the diluted weighted average number of ordinary shares in issue during the period.

Reconciliations of these non-GAAP measures to the most directly comparable IFRS measure are included in the accompanying tables.
