RigNet Announces Third Quarter 2015 Earnings Results

HOUSTON – November 9, 2015 – RigNet, Inc. (NASDAQ: RNET), a leading global provider of managed remote communications solutions to the oil and gas industry, today reported quarterly results for the quarter ended September 30, 2015.

Quarterly revenue was $66.3 million, representing decreases of $21.5 million, or 24.5%, and $8.8 million, or 11.7%, respectively, as compared to the prior year and prior quarters. Telecoms Systems Integration contributed $8.2 million and $4.9 million, respectively, to the revenue decline as compared to the prior year and prior quarters, primarily as a result of reduced activity and backlog. Managed Services revenue decreased $13.3 million and $3.9 million, respectively, as compared to the prior year and prior quarters, primarily due to reduced spending by oil and gas operators on upstream drilling projects as a result of lower commodity prices.

Quarterly Adjusted EBITDA was $14.5 million, or 21.9% of revenue, representing decreases of $5.7 million, or 28.2%, and $4.0 million, or 21.7%, respectively, over the prior year and prior quarters. These decreases resulted primarily from lower revenue partially offset by benefits from cost containment actions.

Quarterly Cash Earnings were $12.2 million, or $0.69 per diluted share, representing decreases of $2.6 million, or 17.7%, and $3.2 million, or 20.5%, respectively, over the prior year and prior quarters.

Capital expenditures were $6.1 million compared to $10.0 million in the prior year quarter. Unlevered Free Cash Flow, defined as Adjusted EBITDA less capital expenditures, was $8.4 million, a decrease of $1.8 million, or 17.6%, over the prior year quarter.

Included in the 2015 financial results, the Company has recorded a $12.6 million charge related to impairment of goodwill and intangibles in the three and nine months ended September 30, 2015 in our North America land operations. Additionally, the Company has incurred $1.3 million and $7.5 million of restructuring charges for the three and nine months ended September 30, 2015, respectively, related to resource reallocation and headcount reductions implemented in connection with the decline in oil and gas activity. Both the impairment of goodwill and intangibles and restructuring charges are added back to net income in our non-GAAP measures below.

Mark B. Slaughter, chief executive officer and president, commented, “The RigNet team executed well in the quarter, including winning new sites and new customers, but reduced customer spending impacted our existing business as offshore rigs were stacked and scrapped. We further adjusted our cost structure in the quarter to align with market activity levels while maintaining customer service levels and long-term investments important for when market conditions improve. Our efforts continue to strengthen our capabilities, defend and expand our market presence and overall emerge as a better company. Moreover, with our strong financial position, we are well-positioned to execute against our long-term growth plans, both organically and inorganically, under the current market conditions.”

Non-GAAP Financial Measures

This press release contains the following non-GAAP measures: Gross Profit (excluding depreciation and amortization), Adjusted EBITDA, Unlevered Free Cash Flow, Cash Earnings and Cash EPS. Gross Profit (excluding depreciation and amortization), Adjusted EBITDA, Unlevered Free Cash Flow, Cash Earnings and Cash EPS are financial measures that are not calculated in accordance with generally accepted accounting principles, or GAAP. We refer you to the Company’s most recent 10-K and 10-Q filings for the year ended December 31, 2014 and the three and nine months ended September 30, 2015, respectively, for a more detailed discussion of the uses and limitations of our non-GAAP financial measures.

GAAP defines gross profit as revenue less cost of revenue, and includes in costs of revenue depreciation and amortization expenses related to revenue-generating long-lived and intangible assets. We define Gross Profit (excluding depreciation and amortization) as revenue less cost of revenue (excluding depreciation and amortization). This measure differs from the GAAP definition of gross profit as we do not include the impact of depreciation and amortization expenses related to revenue-generating long-lived and intangible assets which represent non-cash expenses. We use this measure to evaluate operating margins and the effectiveness of cost management.

We define Adjusted EBITDA as net income (loss) plus interest expense, income tax expense (benefit), depreciation and amortization, impairment of goodwill, foreign exchange impact of intercompany financing activities, (gain) loss on retirement of property, plant and equipment, change in fair value of derivatives, stock-based compensation, IPO or merger/acquisition costs and related bonuses, restructuring charges and non-recurring items. Adjusted EBITDA should not be considered as an alternative to net income (loss), operating income (loss) or any other measure of financial performance calculated and presented in accordance with GAAP.

We define Unlevered Free Cash Flow as Adjusted EBITDA less capital expenditures. Unlevered Free Cash Flow should not be considered as an alternative to net income (loss), operating income (loss) or any other measure of financial performance calculated and presented in accordance with GAAP.

We define Cash Earnings as net income (loss), plus depreciation and amortization, impairment of goodwill, foreign exchange impact of intercompany financing activities, (gain) loss on retirement of property and equipment, change in fair value of derivatives, stock-based compensation, IPO or merger/acquisition costs and related bonuses, restructuring charges and non-recurring items. We define Cash EPS as Cash Earnings divided by diluted shares. Cash Earnings and Cash EPS should not be considered as an alternative to net income (loss), operating income (loss), basic or diluted earnings per share or any other measure of financial performance calculated and presented in accordance with GAAP.
