4Q19 & FISCAL YEAR OPERATIONAL HIGHLIGHTS

(4Q19 results are compared to 4Q18. FY 2019 results are compared to FY 2018)

REMARKS BY SHMUEL JONAS, CEO

“Our growth initiatives – net2phone’s UCaaS offerings, National Retail Solutions and our BOSS Revolution international money transfer service – continued their rapid expansions in the fourth quarter.

“As expected, revenue from our core Carrier Services and BOSS Revolution Calling offerings continued to decrease as a result of industry-wide headwinds in the paid minute communications market, but the company-wide margin impact was dampened by increased contributions from our growth initiatives. Consolidated revenue less direct cost of revenue has increased sequentially in each of the last three quarters.

“Consolidated Adjusted EBITDA* was $7.4 million in the fourth quarter. In the year ago quarter, consolidated Adjusted EBITDA was $16.8 million -- a significant outlier to the upside as a result of changes to estimates for recognizing breakage revenue. For the full fiscal year, consolidated Adjusted EBITDA was $30.8 million compared to $38.2 million in fiscal 2018.

“Overall, the fourth quarter marked a consistent end to a solid year, and I want to thank everyone in our company for all their hard work. As fiscal 2020 gets underway, we are working from a strong position to vigorously pursue our exciting growth opportunities.”

Notes on Consolidated Results and Balance Sheet

Income from operations and net income include accruals of $2.6 million, $2.3 million and $8.0 million for 4Q19, 3Q19 and FY 2019, respectively, for non-income related taxes pertaining to one of our foreign entities in our Telecom & Payment Services (TPS) segment. Also within TPS, 4Q18 revenue increased $9.5 million as a result of changes to estimates for recognizing certain breakage revenue, and direct cost increased by $4.5 million as a result of a change in accrued regulatory fee expense. Consolidated and TPS revenue less direct cost increased by the net of the changes, $5.0 million.

Consolidated results for all periods presented include corporate overhead. Corporate G&A expense decreased to $2.1 million in 4Q19 from $2.6 million in 4Q18, and decreased to $9.2 million in FY 2019 from $9.8 million in FY 2018.

At July 31, 2019, IDT held $88.4 million in unrestricted cash, cash equivalents, debt securities and current equity investments. Current assets totaled $368.5 million and current liabilities totaled $389.1 million. As of 3Q19, IDT no longer classifies its Gibraltar-based bank’s assets and liabilities as “held for sale” in the consolidated balance sheets for all periods presented.

On August 1, 2018, IDT adopted a change in GAAP related to the classification and presentation of changes in restricted cash in the statement of cash flows and has conformed prior period results.

Net cash provided by operating activities during 4Q19 was $37.8 million, including a $26.0 million increase in customer deposits at IDT’s Gibraltar-based bank, compared to $19.3 million in the year ago quarter, including a $3.8 million reduction in customer deposits. In the corresponding periods, capital expenditures were $5.0 million and $4.6 million, respectively. FY 2019 net cash provided by operating activities was $85.1 million including a $59.1 million increase in customer deposits at IDT’s Gibraltar-based bank, compared to $20.4 million in FY 2018 including a $14.7 million increase in customer deposits. In the corresponding periods, capital expenditures were $18.7 million and $20.6 million, respectively.

4Q19 AND FISCAL YEAR 2019 RESULTS BY SEGMENT

(4Q19 results are compared to 4Q18 and FY 2019 results are compared to FY 2018).

Beginning with fiscal year 2019, IDT has modified the way it reports its business verticals within its two reporting segments to align more closely with IDT’s business strategy and operational structure, as follows:

Telecom & Payment Services (TPS)

IDT’s TPS segment accounted for 96.4% and 97.5% of IDT’s consolidated revenue in 4Q19 and 4Q18, respectively, and 96.6% and 97.7% of consolidated revenue in FY 2019 and FY 2018, respectively. The segment includes Core and Growth verticals:

Core includes IDT’s three largest communications and payments offerings from both a revenue and cash generation perspective: BOSS Revolution Calling, an international long-distance calling service marketed primarily to immigrant communities in the US; Carrier Services, which provides international long-distance termination and outsourced traffic management solutions to telecoms worldwide, and; Mobile Top-Up, which enables customers to transfer airtime and bundles of airtime, messaging and data credits to mobile phones overseas and within the US. TPS Core also includes smaller communications and payments offerings – some of which are in harvest mode.

Growth is comprised of NRS’ retailer POS terminal-based services, the BOSS Revolution international money transfer service, and the BOSS Revolution Mobile service.

net2phone

IDT’s net2phone segment accounted for 3.6% and 2.5% of IDT’s consolidated revenue in 4Q19 and 4Q18, respectively, and 3.4% and 2.3% of FY 2019 and FY 2018 consolidated revenue, respectively. The segment comprises two verticals:

net2phone-UCaaS comprises unified cloud communications in the US and certain international markets and SIP-trunking offerings in South America.

net2phone-Platform Services includes other offerings leveraging a common technology platform to provide cable telephony and other voice services.

Revenue in 4Q19, fiscal year 2019 and comparative periods for all verticals and the most significant core offerings is provided in the following chart:

Reconciliation of Non-GAAP Financial Measures for the

Fourth Quarter and Full Fiscal Years 2019 and 2018

In addition to disclosing financial results that are determined in accordance with generally accepted accounting principles in the United States of America (GAAP), IDT also disclosed, for 4Q19, 3Q19, 4Q18 and the full fiscal years 2019 and 2018, Adjusted EBITDA, non-GAAP net income and non-GAAP earnings per share, which are non-GAAP measures. Generally, a non-GAAP financial measure is a numerical measure of a company’s performance, financial position, or cash flows that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP.

IDT’s measure of Adjusted EBITDA consists of revenue less direct cost of revenues and selling, general and administrative expense. Another way of calculating Adjusted EBITDA is to start with income from operations, add depreciation and amortization, severance expense, and other operating expense, and deduct other gains, net.

IDT’s measure of non-GAAP net income starts with net income in accordance with GAAP and adds severance expense, stock-based compensation, and other operating expense, net, and subtracts the income tax benefit from The Tax Cuts and Jobs Act.

IDT’s measure of non-GAAP earnings per share is calculated by dividing non-GAAP net income by the diluted weighted-average shares.

These additions and subtractions are non-cash and/or non-routine items in the relevant fiscal 2019 and fiscal 2018 periods.

Management believes that IDT’s Adjusted EBITDA, non-GAAP net income and non-GAAP earnings per share measures provide useful information to both management and investors by excluding certain expenses and non-routine gains and losses that may not be indicative of IDT’s or the relevant segment’s core operating results. Management uses Adjusted EBITDA, among other measures, as a relevant indicator of core operational strengths in its financial and operational decision making. In addition, management uses Adjusted EBITDA, non-GAAP net income and non-GAAP earnings per share to evaluate operating performance in relation to IDT’s competitors. Disclosure of these financial measures may be useful to investors in evaluating performance and allows for greater transparency to the underlying supplemental information used by management in its financial and operational decision-making. In addition, IDT has historically reported similar financial measures and believes such measures are commonly used by readers of financial information in assessing performance, therefore the inclusion of comparative numbers provides consistency in financial reporting at this time.

Management refers to Adjusted EBITDA, as well as the GAAP measures (loss) income from operations and net income, on a segment and/or consolidated level to facilitate internal and external comparisons to the segments’ and IDT’s historical operating results, in making operating decisions, for budget and planning purposes, and to form the basis upon which management is compensated.

While depreciation and amortization are considered operating costs under GAAP, these expenses primarily represent the non-cash current period allocation of costs associated with long-lived assets acquired or constructed in prior periods. IDT’s Adjusted EBITDA, which is exclusive of depreciation and amortization, is a useful indicator of its current performance.

Severance expense is excluded from the calculation of Adjusted EBITDA, non-GAAP net income and non-GAAP earnings per share. Severance expense is reflective of decisions made by management in each period regarding the aspects of IDT’s and its segments’ businesses to be focused on in light of changing market realities and other factors. While there may be similar charges in other periods, the nature and magnitude of these charges can fluctuate markedly and do not reflect the performance of IDT’s core and continuing operations.

Other operating expense, net, which is a component of (loss) income from operations, is excluded from the calculation of Adjusted EBITDA, non-GAAP net income and non-GAAP earnings per share. In 4Q19, 3Q19 and fiscal 2019, other operating expense, net included an accrual for non-income related taxes related to one of our foreign entities. In fiscal 2019 and fiscal 2018, other operating expense, net also included legal fees net of insurance proceeds related to Straight Path Communications Inc.’s stockholders’ putative class action and derivative complaint. In addition, in 2Q19, other operating expense, net included a gain on the sale of a calling card business in Asia. From time-to-time, IDT may incur costs related to non-routine tax, legal and regulatory matters or disposal of certain assets. However, these matters and disposals do not occur each quarter. IDT does not believe the gains or losses from these non-routine matters or asset sales are components of IDT’s or the relevant segment’s core operating results.

The other calculation of Adjusted EBITDA consists of revenue less direct cost of revenues and selling, general and administrative expense. As the other excluded items are not reflected in this calculation, they are excluded automatically and there is no need to make additional adjustments. This calculation results in the same Adjusted EBITDA amount and its utility and significance is as explained above.

Stock-based compensation recognized by IDT and other companies may not be comparable because of the variety of types of awards as well as the various valuation methodologies and subjective assumptions that are permitted under GAAP. Stock-based compensation is excluded from IDT’s calculation of non-GAAP net income and non-GAAP earnings per share because management believes this allows investors to make more meaningful comparisons of the operating results per share of IDT’s core business with the results of other companies. However, stock-based compensation will continue to be a significant expense for IDT for the foreseeable future and an important part of employees’ compensation that impacts their performance.

In 2Q18, IDT recorded an income tax benefit of $3.3 million for its anticipated AMT credit refund due to The Tax Cuts and Jobs Act enacted in December 2017. This income tax benefit is excluded from IDT’s calculation of non-GAAP net income and non-GAAP earnings per share because it was not directly related to the results of IDT’s core operations.

Adjusted EBITDA, non-GAAP net income and non-GAAP earnings per share should be considered in addition to, not as a substitute for, or superior to, income (loss) from operations, cash flow from operating activities, net income, basic and diluted earnings per share or other measures of liquidity and financial performance prepared in accordance with GAAP. In addition, IDT’s measurements of Adjusted EBITDA, non-GAAP net income and non-GAAP earnings per share may not be comparable to similarly titled measures reported by other companies.

Following are reconciliations of Adjusted EBITDA, non-GAAP net income and non-GAAP earnings per share to the most directly comparable GAAP measure, which are, (a) for Adjusted EBITDA, (loss) income from operations for IDT’s reportable segments and net income for IDT on a consolidated basis, (b) for non-GAAP net income, net income, and (c) for non-GAAP earnings per share, basic and diluted earnings per share.
