HOUSTON – May 1, 2019 – ION Geophysical Corporation (NYSE: IO) today reported revenues of $37.0 million in the first quarter 2019, a 10% increase compared to revenues of $33.5 million one year ago, driven in part by an increase in data library sales and Marlin™ deployments. ION’s net loss was $21.4 million, or $(1.52) per share, compared to a net loss of $18.4 million, or $(1.44) per share in the first quarter 2018.

Net cash flows from operations were $15.4 million during the first quarter 2019, compared to $0.6 million in the first quarter 2018. Total net cash flows, including investing and financing activities, were $5.0 million, compared to $(1.3) million one year ago. At March 31, 2019, the Company had total liquidity of $78.1 million, consisting of $38.4 million of cash on hand, and $39.7 million of available borrowing capacity under its $50.0 million revolving credit facility, of which nothing was drawn.

Brian Hanson, ION’s President and Chief Executive Officer, commented, “I’m pleased with the start to the year given the uncertain market outlook many of our E&P clients had in December due to oil price volatility. While 2019 E&P spending levels are projected to be slightly up, it remains unclear how robust exploration activity and funding will be in 2019. However, we are cautiously optimistic given the uptick in new venture interest we’re seeing.

“We continue to believe market fundamentals will gradually improve as it becomes increasingly critical to meet production demand in the next decade. Oil and gas projections suggest continued demand growth may create a supply gap in the middle of the next decade that shale may be unable to meet, necessitating offshore deepwater exploration and development. Due to the time it takes to develop and start producing oil and gas from new discoveries offshore, there’s an increasing need to reinvest in conventional resources offshore to meet demand in the middle of the next decade.

“Near-term, however, we expect exploration spending will remain very focused, with the majority of data sales tied to license rounds closing this year. We remain focused on an increase in new multi-client program development, commercialization of our 4Sea next generation ocean bottom technology and greater adoption of Marlin offshore operations optimization software in both E&P and adjacent markets.”

Within the E&P Technology & Services segment, multi-client revenues were $23.4 million, an increase of 19%, with data library revenues increasing 67% and new venture revenues essentially flat compared to the first quarter 2018. The increase in data library revenues was primarily attributable to higher sales of recently completed 3D reimaging programs and existing 2D data offshore Brazil. Imaging Services revenues were $3.7 million, a decrease of 25%. While Imaging Services revenues declined, a significant number of new projects closed during the quarter, increasing Imaging Services backlog to its highest level since 2015. This increase in backlog should lead to an increase in Imaging Services revenues during the remainder of 2019.

Within the Operations Optimization segment, Optimization Software & Services revenues were $5.0 million, a 5% increase from the first quarter 2018. The increase in Optimization Software & Services revenues was due to an increase in engineering services revenues, primarily driven by the continued increase in market adoption and deployments of ION’s Marlin offshore operations optimization software. Devices revenues were $4.8 million, a 16% increase from the first quarter 2018, driven by an increase in repairs.

Consolidated gross margin for the quarter was 27%, compared to 20% in the first quarter 2018. Gross margin in E&P Technology & Services was 20%, compared to 18% one year ago. The slight increase in E&P Technology & Services gross margin was a result of the increase and mix of data library revenues. Operations Optimization gross margin was 46%, compared to 48% one year ago. The slight decline in Operations Optimization gross margin was due to the mix of revenues between Devices and Optimization Software & Services.

Consolidated operating expenses were $25.8 million, compared to $19.5 million in the first quarter 2018. Operating margin was (43)%, compared to (38)% in the first quarter 2018. This increase in operating expenses and decline in operating margin was due in part to an increase in compensation expense related to the Company’s outstanding stock appreciation rights (SARs). Outstanding SARs are measured and adjusted to their fair value each quarter until exercised. During the first quarter 2019, the Company recorded $4.5 million of SARs expenses compared to $1.2 million in first quarter 2018.

The term Adjusted EBITDA represents net loss before interest expense, interest income, income taxes and depreciation and amortization charges. Adjusted EBITDA is not a measure of financial performance under generally accepted accounting principles and should not be considered in isolation from or as a substitute for net income (loss) or cash flow measures prepared in accordance with generally accepted accounting principles or as a measure of profitability or liquidity. Additionally, Adjusted EBITDA may not be comparable to other similarly titled measures of other companies. The Company has included Adjusted EBITDA as a supplemental disclosure because its management believes that Adjusted EBITDA provides investors a helpful measure for comparing its operating performance with the performance of other companies that have different financing and capital structures or tax rates. The Company had previously reported stock appreciation rights (SARs) expense as an adjustment to its Adjusted EBITDA due to the unusual nature associated with accelerated vesting of certain SARs awards. Since such condition no longer exists and considering the recurring nature of recording outstanding SARs at their fair value, the Company has ceased reflecting SARs expense as an adjustment to its Adjusted EBITDA. To assist with comparability, the Company has reduced its previously reported Adjusted EBITDA by $1.2 million related to SARs expense in the first quarter 2018.
