LENDINGTREE INTRODUCES 2019 GUIDANCE AHEAD OF INVESTOR DAY

CHARLOTTE, NC - December 4, 2018 - LendingTree, Inc. (NASDAQ: TREE), operator of LendingTree.com, the nation's leading online loan marketplace, today introduced financial guidance for fiscal year 2019 ahead of the Company’s Analyst and Investor Day.

The Analyst and Investor event is being hosted in New York at the Andaz Fifth Avenue in Midtown Manhattan.  The presentation will begin promptly at 10:30 a.m. ET.  A live audiocast with accompanying slides will be made available on the company's investor relations website at investors.lendingtree.com.

"2018 has been another record setting year at LendingTree, and we are thrilled with what we've accomplished this year despite a difficult environment for the mortgage industry" said Doug Lebda, Chairman and CEO.  "Our diversification over the last several years has enabled us to navigate a challenging period and will continue to be advantageous for us in the years to come.  Today, we introduce our outlook for 2019 and I look forward to sharing that and more with analysts and investors throughout the course of the day."

Business Outlook - 2019

LendingTree is providing Revenue, Variable Marketing Margin and Adjusted EBITDA guidance for full-year 2019, as follows:

• Revenue is anticipated to be in the range of $990 - $1,030 million, representing growth of 29% - 34% over the midpoint of full-year 2018 revenue guidance of $765 - $775 million.

• Variable Marketing Margin is anticipated to be $365 - $385 million.

• Adjusted EBITDA is anticipated to be in the range of $195 - $205 million, up 27% - 34% over the midpoint of full-year 2018 Adjusted EBITDA guidance of $152 - $155 million.

LendingTree is not able to provide a reconciliation of projected Variable Marketing Margin or Adjusted EBITDA to the most directly comparable expected GAAP results due to the unknown effect, timing and potential significance of the effects of legal matters, contingent consideration and income taxes.  These expenses or benefits have in the past, and may in the future, significantly affect GAAP results in a particular period.

LendingTree's Principles of Financial Reporting

LendingTree reports Variable Marketing Margin and Earnings Before Interest, Taxes, Depreciation and Amortization, as adjusted for certain items discussed below ("Adjusted EBITDA") as non-GAAP measures supplemental to GAAP.

Variable Marketing Margin is defined as revenue less Variable Marketing Expense. Variable Marketing Expense is defined as the expense attributable to variable costs paid for advertising, direct marketing and related expenses, including the portion of cost of revenue attributable to costs paid for advertising re-sold to third parties, and excluding overhead, fixed costs and personnel-related expenses. The majority of these variable advertising costs are expressly intended to drive traffic to our websites and these variable advertising costs are included in selling and marketing expense on the company's consolidated statements of operations and consolidated income. When advertising inventory is re-sold to third parties, the proceeds of such transactions are included in revenue for the purposes of calculating Variable Marketing Margin, and the costs of such re-sold advertising are included in cost of revenue in the Company's consolidated statements of operations and consolidated income and are included in Variable Marketing Expense for purposes of calculating Variable Marketing Margin. Variable Marketing Margin is a measure of the operating efficiency of the Company's operating model, measuring revenue after subtracting variable marketing costs that directly influence revenue. The Company's operating model is highly sensitive to the amount and efficiency of variable marketing expenditures, and the Company's proprietary systems are able to make rapidly changing decisions concerning the deployment of variable marketing expenditures (primarily but not exclusively online and mobile advertising placement) based on proprietary and sophisticated analytics. Variable Marketing Margin is a primary metric by which the Company measures the effectiveness of its marketing efforts.

EBITDA is defined as net income from continuing operations excluding interest, income taxes, amortization of intangibles and depreciation. Adjusted EBITDA is defined as EBITDA excluding (1) non-cash compensation expense, (2) non-cash impairment charges, (3) gain/loss on disposal of assets, (4) restructuring and severance expenses, (5) litigation settlements, contingencies and legal fees for certain patent litigation, (6) acquisitions and dispositions income or expense (including with respect to changes in fair value of contingent consideration), and (7) one-time items. Adjusted EBITDA is a primary metric by which LendingTree evaluates the operating performance of its businesses, on which its marketing expenditures and internal budgets are based and by which management and many employees are compensated.

The most directly comparable GAAP measure for both Variable Marketing Margin and Adjusted EBITDA is net income from continuing operations.

LendingTree endeavors to compensate for the limitations of these non-GAAP measures by also providing the comparable GAAP measures with equal or greater prominence and descriptions of the reconciling items, including quantifying such items, to derive the non-GAAP measures. However, LendingTree is not able to provide a reconciliation of projected Variable Marketing Margin or Adjusted EBITDA to the most directly comparable expected GAAP results due to the unknown effect, timing and potential significance of the effects of legal matters, contingent consideration and income taxes.  These non-GAAP measures may not be comparable to similarly titled measures used by other companies.
