ION reports fourth quarter and year end 2019 results

Fourth quarter revenue declines by 43% and full year by 3%, driven by reduction in multi-client revenues

HOUSTON – February 5, 2020 – ION Geophysical Corporation (NYSE: IO) today reported revenues of $42.7 million in the fourth quarter 2019 compared to fourth quarter revenues of $74.6 million one year ago. ION's net loss for the fourth quarter 2019 was $14.5 million, or a loss of $1.02 per share, compared to a net loss of $19.3 million, or a loss of $1.38 per share in the fourth quarter 2018. Excluding special items in both periods, the Company reported an Adjusted net loss of $5.7 million, or a loss of $0.40 per share, compared to an Adjusted net income of $15.3 million, or $1.07 per diluted share in the fourth quarter 2018. A reconciliation of special items to the reported financial results can be found in the tables of this press release.

For the full year 2019, the Company reported revenues of $174.7 million, a 3% decrease compared to revenues of $180.0 million one year ago. ION's full year 2019 net loss was $48.2 million, or a loss of $3.41 per share, compared to a net loss of $71.2 million, or a loss of $5.20 per share in 2018. Excluding special items in both periods, the Company reported an Adjusted net loss of $33.9 million, or a loss of $2.40 per share, compared to an Adjusted net loss of $32.5 million, or a loss of $2.37 per share in 2018.

Chris Usher, the Company’s President and Chief Executive Officer, commented, “Our fourth quarter financial results were quite disappointing, primarily because we were not able to launch multiple new acquisition multi-client programs and close several data library deals in our pipeline. As a result, our full year results were down slightly, rather than the upward trajectory we had been building towards for 2019, with timing of fourth quarter multi-client deals countering the annual improvements in all our other businesses. Tighter E&P budgetary controls and lower oil prices subdued year-end spending such that several material deals, on the order of tens of millions of dollars, were not completed prior to year-end.

“We are focused on fundamentals and working areas we directly control. We reorganized the business in two ways to improve our execution and accountability; we restructured our E&P Technology & Services segment to reflect our shift in multi-client strategy to include new 3D acquisition, and implemented a significant cost reduction program to lower our operating expenses. We reorganized our new ventures sales organization to accelerate our entry into the 3D new acquisition multi-client market, bringing our projects closer to the reservoir, where capital investment tends to be more consistent and programs have larger scale revenue and earnings potential. ION has rapidly grown our 3D library from almost nothing to 350,000 sq km of seamlessly integrated reimaged data over the last few years, which has given us credibility and experience in the space and led to a pipeline of opportunities for new 3D towed streamer or seabed programs we have not seen before. On the cost side of the equation, we recognize the need to reduce our corporate cost structure. In January 2020,

we executed a program that will improve focus and execution on strategic initiatives while delivering annualized savings of over $20 million.

“With that work behind us, I am still as excited about ION and our business as when I took the CEO role. We are aligned around select initiatives that can uniquely position ION in the new industry landscape with the potential for more satisfying results. Offshore is picking up and we see material activity among our client base to rebalance portfolios and maximize value, which drives related data sales opportunities to fill customer knowledge gaps. Our E&P Technology & Services team has new focus on 3D new acquisition program opportunities, aligned with our leading imaging capabilities. Our Operations Optimization business is growing steadily and we just secured another Marlin™ SmartPort customer after ramping up our port business development capacity.”

The Company reported Adjusted EBITDA of $9.2 million for the fourth quarter 2019, a decrease from the Adjusted EBITDA of $36.5 million one year ago. Adjusted EBITDA was $31.9 million in 2019, compared to $41.7 million in 2018. A reconciliation of Adjusted EBITDA to the closest comparable GAAP numbers can be found in the tables of this press release.

Net cash flows from operations were $14.8 million during the fourth quarter 2019, compared to $14.4 million in the fourth quarter 2018. Total net cash flows, including investing and financing activities, were $4.9 million, compared to $3.4 million one year ago.

Net cash flows from operations were $34.2 million during 2019, compared to $7.1 million in 2018. Total net cash flows, including investing and financing activities, were $(0.7) million in 2019, compared to $(18.6) million in 2018.

At December 31, 2019, the Company had total liquidity of $72.4 million, consisting of $33.1 million of cash on hand, and $39.3 million of available borrowing capacity under its maximum $50.0 million revolving credit facility. There were no outstanding amounts under the credit facility at year-end.

FOURTH QUARTER 2019

The Company's segment revenues for the fourth quarter were as follows (in thousands):



	Three Months Ended December 31,
	2019		2018		% Change
E&P Technology & Services	$	29,711	$	60,443	(51	)%
Operations Optimization	12,998		14,151		(8	)%
Total	$	42,709	$	74,594	(43	)%

Within the E&P Technology & Services segment, multi-client revenues were $23.6 million, a decrease of 57%. The decline in multi-client revenues was the result of reduced new venture revenues and reduced year-end data library spending compared to one year ago. Imaging Services revenues were $6.1 million, a 14% increase. Our Imaging Services' business remains healthy entering 2020 with backlog more than double that of one year ago.

Within the Operations Optimization segment, Optimization Software & Services revenues were $5.5 million, a 9% decline from the fourth quarter 2018, Devices revenues were $7.5 million, an 8% decline. Both groups were modestly down during the quarter due to the normal lumpiness of those businesses.

Consolidated gross margin for the quarter was 12%, compared to 51% in the fourth quarter 2018. Excluding special items impacting only the fourth quarter 2019, consolidated gross margin was 34%, as adjusted. Gross margin in the E&P Technology & Services was (1)%, or 29%, as adjusted, compared to 53% one year ago. The decrease in E&P Technology & Service gross margin, as adjusted, was the result of the decline in multi-client revenues. Operations Optimization gross margin was 43%, compared to 52% one year ago, also the result of a decline in revenues.

Consolidated operating expenses were $15.1 million, compared to $54.5 million in the fourth quarter 2018. Excluding special items, consolidated operating expenses, as adjusted, were $14.9 million, compared to $19.8 million in the fourth quarter 2018, and operating margin, as adjusted, was (1)%, compared to 24% in the fourth quarter 2018. The decline in operating margin, as adjusted, was due to the decrease in revenues, partially offset by the decrease in operating expenses, as adjusted, primarily related to reduced sales and bonus-related compensation expenses.

FULL YEAR 2019

The Company's segment revenues for the full year were as follows (in thousands):



	Years Ended December 31,
	2019		2018		% Change
E&P Technology & Services	$	125,578	$	136,520	(8	)%
Operations Optimization	49,101		43,525		13	%
Total	$	174,679	$	180,045	(3	)%

Within the E&P Technology & Services segment, multi-client revenues were $103.0 million, a decrease of 12%. Full year 2019 data library revenues increased primarily due to sales of South American data, an increase which was more than offset by a decline in new venture revenues. Imaging Services revenues were $22.5 million, an increase of 14%, associated with increased revenues in the second half of 2019. The increase in Imaging Services revenue is attributed to modest market improvement and the successful execution of the Company's strategy to focus on key clients, applications and basins that benefit from and enables ION to continue enhancing its advanced technologies.

Within the Operations Optimization segment, Optimization Software & Services revenues were $23.1 million, an increase of 10% from 2018. The increase in Optimization Software & Services revenues for the full year was the result of increased deployments and associated engineering services related to ION's Marlin offshore operations optimization software. Devices revenues were $26.0 million, a 16% increase from 2018, driven by an increase in marine equipment replacement and repairs.

Consolidated gross margin was 34%, compared to 33% in 2018. Excluding special items impacting only 2019, consolidated gross margin was 40%, as adjusted. Gross margin in the E&P Technology

& Services was 28%, or 36%, as adjusted, compared to 32% in 2018. While full year E&P Technology & Service's revenues declined in 2019, the improvement in gross margin, as adjusted, was the result of the mix of multi-client revenues and increase in Imaging Services revenues. Operations Optimization gross margin was 50%, compared to 51% in 2018.

Consolidated operating expenses were $84.5 million, compared to $113.9 million in 2018. Excluding special items, consolidated operating expenses, as adjusted, were $78.8 million, compared to $75.2 million in 2018, and operating margin, as adjusted, was (6)%, compared to (9)% in 2018. The improvement in operating margin, as adjusted, was due to the mix of revenues, partially offset by the increase in operating expenses, as adjusted, primarily related to compensation expenses.

The term EBITDA (excluding non-recurring items) represents net loss before net interest expense, income taxes, depreciation and amortization and other non-recurring charges such as impairment of long-lived assets and severance expenses. The term Adjusted EBITDA is EBITDA (excluding non-recurring items) but also excludes the impact of fair value adjustments related to the Company’s outstanding stock appreciation awards. EBITDA (excluding non-recurring items) and Adjusted EBITDA are not measures 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, EBITDA (excluding non-recurring items) and Adjusted EBITDA may not be comparable to other similarly titled measures of other companies. The Company has included EBITDA (excluding non-recurring items) and Adjusted EBITDA as a supplemental disclosure because its management believes that EBITDA (excluding non-recurring items) and 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.

Description of Special Items and Reconciliation of GAAP (As Reported) to Non-GAAP (As Adjusted) Measures

(Non-GAAP Measure)

(In thousands, except per share data)

(Unaudited)

The financial results are reported in accordance with GAAP. However, management believes that certain non-GAAP performance measures may provide users of this financial information, additional meaningful comparisons between current results and results in prior operating periods. One such non-GAAP financial measure is income (loss) from operations or net income (loss) excluding certain charges or amounts. This adjusted income (loss) amount is not a measure of financial performance under GAAP. Accordingly, it should not be considered as a substitute for income (loss) from operations, net income (loss) or other income data prepared in accordance with GAAP. See the table below for supplemental financial data and the corresponding reconciliation to GAAP financials for the three and twelve months ended December 31, 2019 and 2018.
