– Adjusted EBITDA of $23.6 Million, includes Approximately $1.0 Million of Cost Savings and Customer Installation Delays

RESTON, VA - (May 9, 2019) Internap  Corporation (NASDAQ: INAP), a leading-edge provider of high-performance data center and cloud solutions with global network connectivity, announced today financial results for the first quarter of 2019.

“We have significant opportunities ahead to grow INAP and gain scale with our reconstructed portfolio.  Year-over-year, management exited non-core data centers, and added a premier managed services platform through SingleHop to create a new baseline by the end of the first quarter of 2019.  This portfolio right-sizing is now completed and establishes a new and improved INAP platform of colo, cloud and network services,” said Peter D. Aquino, President and Chief Executive Officer. “In addition, we are pleased to report the completed amendment to INAP’s credit facility as a follow-on to our recent equity raise.  This operational flexibility positions the INAP platform for growth, partnerships and potential mergers.  As we evaluate the opportunities to create shareholder value, we have retained Moelis & Company LLC and LionTree Advisors LLC as Financial Advisors.”

Revenue

2018 results include SingleHop LLC (“SingleHop”) operations beginning March 1, 2018, and are therefore not comparable to prior periods.

· Total company revenue was $73.6 million in the first quarter of 2019, a decrease sequentially of $4.7 million or 6.0% and a decrease of $0.6 million or nearly flat at 0.9% year-over-year.  The sequential decrease was primarily due to planned data centers exits and resizing of certain customer footprints of $2.0 million, lower non-recurring revenues associated with installs and timing for $1.0 million, deferred revenue adjustments of $0.6 million and other decreases of $0.9 million.  The sequential decreases are primarily related to the reshaping initiatives of the colocation product line.

o INAP US revenue totaled $57.5 million in the first quarter of 2019, a decrease of 6.3% sequentially and an increase of 0.8% year-over-year. The sequential decrease was due primarily to all of the above.

o INAP INTL revenue was $16.0 million in the first quarter of 2019, a decrease of 4.9% sequentially and 6.3% year-over-year. The decrease sequentially was primarily due to a decline in the Canada cloud business that targets smaller customers. The decrease year-over-year was partly offset by the addition of SingleHop.

INTERNAP CORPORATION

NON-GAAP (ADJUSTED) FINANCIAL MEASURES

In addition to providing financial measurements based on accounting principles generally accepted in the United States of America (“GAAP”), this earnings press release includes additional financial measures that are not prepared in accordance with GAAP (“non-GAAP”), including Adjusted EBITDA, Adjusted EBITDA margin, Adjusted EBITDA less CapEx, normalized net loss, business unit contribution, business unit contribution margin, free cash flow and unlevered free cash flow. A reconciliation of non-GAAP financial measures to the most directly comparable GAAP financial measures can be found below.

We define the following non-GAAP measures as follows:

• Adjusted EBITDA is a non-GAAP measure and is GAAP net loss attributable to INAP shareholders plus depreciation and amortization, interest expense, provision (benefit) for income taxes, other (income) expense, (gain) loss on disposal of property and equipment, exit activities, restructuring and impairments, stock-based compensation, non-income tax contingency, strategic alternatives and related costs, organizational realignment costs, acquisition costs and claim settlement.

• Adjusted EBITDA margin is Adjusted EBITDA as a percentage of revenues.

• Adjusted EBITDA less CapEx is Adjusted EBITDA less capital expenditures with Adjusted EBITDA for this non-GAAP measure defined as net cash flow provided by operating activities plus cash paid for interest, cash paid for income taxes, cash paid for exit activities and restructuring, cash paid for strategic alternatives and related costs, cash paid for organizational realignment costs and other working capital changes less capital expenditures.

• Normalized net loss is GAAP net loss attributable to INAP shareholders plus exit activities, restructuring and impairments, stock-based compensation, non-income tax contingency, strategic alternatives, realignment and related costs and acquisition costs.

• Business unit contribution is business unit revenues less direct costs of sales and services, customer support, and sales and marketing, exclusive of depreciation and amortization.

• Business unit contribution margin is business unit contribution as a percentage of business unit revenue.

• Free cash flow is net cash flows provided by operating activities minus capital expenditures.

• Unlevered free cash flow is free cash flow plus cash interest expense.

We believe that presentation of these non-GAAP financial measures provides useful information to investors regarding our results of operations.

We believe that excluding depreciation and amortization and (gain) loss on disposals of property and equipment, as well as restructuring and impairments, to calculate Adjusted EBITDA provides supplemental information and an alternative presentation that is useful to investors’ understanding of our current ongoing operating results and trends. Not only are depreciation and amortization expenses based on historical costs of assets that may have little bearing on present or future replacement costs, but also they are based on management estimates of remaining useful lives. Loss on disposals of property and equipment is also based on historical costs of assets that may have little bearing on replacement costs. Impairments and restructuring expenses primarily reflect goodwill impairments and subsequent plan adjustments in sublease income assumptions for certain properties included in our previously disclosed restructuring plans.

We believe that excluding interest expense, provision (benefit) for income taxes and other (income) expense from non-GAAP financial measures provides supplemental information and an alternative presentation useful to investors’ understanding of our core operating results and trends. Investors have indicated that they consider financial measures of our results of operations excluding interest expense, provision (benefit) for income taxes and other (income) expense as important supplemental information useful to their understanding of our historical results and estimating our future results.

We also believe that, in excluding the effects of interest expense, provision (benefit) for income taxes and other (income) expense, our non-GAAP financial measures provide investors with transparency into what management uses to measure and forecast our results of operations, to compare on a consistent basis our results of operations for the current period to that of prior periods and to compare our results of operations on a more consistent basis against that of other companies, in making financial and operating decisions and to establish certain management compensation.

We believe that exit activities, restructuring and impairment charges, non-income tax contingency, strategic alternatives and related costs, organizational realignment costs, acquisition costs and claim settlement costs are unique costs, and consequently, we do not consider these charges as a normal component of expenses related to current and ongoing operations.

Similarly, we believe that excluding the effects of stock-based compensation from non-GAAP financial measures provides supplemental information and an alternative presentation useful to investors’ understanding of our current ongoing operating results and trends. Management believes that investors consider financial measures of our results of operations excluding stock-based compensation as important supplemental information useful to their understanding of our historical results and estimating our future results.

We also believe that, in excluding the effects of stock-based compensation, our non-GAAP financial measures provide investors with transparency into what management uses to measure and forecast our results of operations, to compare on a consistent basis our results of operations for the current period to that of prior periods and to compare our results of operations on a more consistent basis against that of other companies, in making financial and operating decisions and to establish certain management compensation.

Stock-based compensation is an important part of total compensation, especially from the perspective of employees. We believe, however, that supplementing GAAP net loss by providing normalized net loss, excluding the effect of exit activities, restructuring and impairments, stock-based compensation, non-income tax contingency, strategic alternatives and related costs, organizational realignment costs, acquisition costs and claim settlement costs, in all periods, is useful to investors because it enables additional and more meaningful period-to-period comparisons.

Adjusted EBITDA is not a measure of financial performance calculated in accordance with GAAP, and should be viewed as a supplement to - not a substitute for - our results of operations presented on the basis of GAAP. Adjusted EBITDA does not purport to represent cash flow provided by operating activities as defined by GAAP. Our statements of cash flows present our cash flow activity in accordance with GAAP. Furthermore, Adjusted EBITDA is not necessarily comparable to similarly-titled measures reported by other companies.

We believe Adjusted EBITDA is used by and is useful to investors and other users of our financial statements in evaluating our operating performance because it provides them with an additional tool to compare business performance across companies and across periods. We believe that:

• EBITDA is widely used by investors to measure a company’s operating performance without regard to items such as interest expense, income taxes, depreciation and amortization, which can vary substantially from company-to-company depending upon accounting methods and book value of assets, capital structure and the method by which assets were acquired; and

• investors commonly adjust EBITDA information to eliminate the effect of disposals of property and equipment, impairments, restructuring and stock-based compensation which vary widely from company-to-company and impair comparability.

NON-GAAP (ADJUSTED) FINANCIAL MEASURES (Continued)

Our management uses Adjusted EBITDA:

• as a measure of operating performance to assist in comparing performance from period-to-period on a consistent basis;

• as a measure for planning and forecasting overall expectations and for evaluating actual results against such expectations; and

• in communications with the board of directors, analysts and investors concerning our financial performance.

Our presentation of business unit contribution and business unit contribution margin excludes depreciation and amortization in order to allow investors to see the business through the eyes of management.

We also have excluded depreciation and amortization from business unit contribution and business unit contribution margin because, as noted above, they are based on estimated useful lives of tangible and intangible assets. Further, depreciation and amortization are based on historical costs incurred to build out our deployed network and the historical costs of these assets may not be indicative of current or future capital expenditures.

Free cash flow and unlevered free cash flow are used in addition to and in conjunction with results presented in accordance with GAAP. Free cash flow and unlevered free cash flow should not be relied upon to the exclusion of GAAP financial measures. Free cash flow and unlevered free cash flow reflect an additional way of viewing our liquidity that, when viewed with our GAAP results, provides a more complete understanding of factors and trends affecting our cash flows. Management strongly encourages investors to review our financial statements and publicly-filed reports in their entirety and to not rely on any single financial measure.

We use free cash flow and unlevered free cash flow, and ratios based on it, to conduct and evaluate our business because, although it is similar to cash flow from operations, we believe it is a useful measure of cash flows since capital expenditures are a necessary component of ongoing operations. In limited circumstances in which proceeds from sales of fixed assets exceed capital expenditures, free cash flow would exceed cash flow from operations. However, since we do not anticipate being a net seller of fixed assets, we expect free cash flow to be less than operating cash flows.

Free cash flow and unlevered free cash flow have limitations due to the fact that they do not represent the residual cash flow available for discretionary expenditures. For example, free cash flow does not incorporate payments made to service our debt or capital lease obligations. Therefore, we believe it is important to view free cash flow as a complement to our entire consolidated statements of cash flows.

Adjusted EBITDA less CapEx is used in addition to and in conjunction with results presented in accordance with GAAP.  Adjusted EBITDA less CapEx should not be relied upon to the exclusion of GAAP financial measures. Adjusted EBITDA less CapEx reflects an additional way of viewing our liquidity that, when viewed with our GAAP results, provides a more complete understanding of factors and trends affecting our cash flows. Management strongly encourages investors to review our financial statements and publicly-filed reports in their entirety and to not rely on any single financial measure.

We use Adjusted EBITDA less CapEx, and ratios based on it, to conduct and evaluate our business because, although it is similar to cash flow from operations, we believe it is a useful measure of cash flows since capital expenditures are a necessary component of ongoing operations.

Adjusted EBITDA less CapEx has limitations due to the fact that it does not represent the residual cash flow available for discretionary expenditures. Adjusted EBITDA less CapEx does not incorporate payments made to service our debt or capital lease obligations. Therefore, we believe it is important to view Adjusted EBITDA less CapEx as a complement to our entire consolidated statements of cash flows.

Adjusted EBITDA, as presented, may not be comparable to similarly titled measures of other companies. Adjusted EBITDA is presented as we understand certain investors use it as one measure of our historical ability to service debt. Also Adjusted EBITDA is used in our debt covenants.

NON-GAAP (ADJUSTED) FINANCIAL MEASURES (Continued)

Although we believe, for the foregoing reasons, that our presentation of non-GAAP financial measures provides useful supplemental information to investors regarding our results of operations, our non-GAAP financial measures should only be considered in addition to, and not as a substitute for, or superior to, any measure of financial performance prepared in accordance with GAAP.
