THE WOODLANDS, TX, April 27, 2020 - Apergy Corporation (“Apergy”) (NYSE: APY) today announced preliminary first quarter 2020 results. Revenue for the quarter was $261.4 million and net loss attributable to Apergy was $659.5 million, which includes an estimated non-cash pre-tax charge of $682.8 million related to the impairment of goodwill and long-lived assets in our Production & Automation Technologies segment. The final computation of the loss resulting from the impairment calculation is expected to be in a range of $650 million to $750 million. The impairment loss was triggered by the substantial negative impact on oil demand caused by COVID-19, in combination with the significant increases in supply coming from OPEC+ members. Adjusted net income attributable to Apergy was $2.8 million, and adjusted EBITDA was $53.3 million. Loss before income taxes margin was (262.4)%, and adjusted EBITDA margin was 20.4%. Cash provided by operating activities was $29.2 million, an increase of $9.3 million on a year-over-year basis, and free cash flow was $21.8 million.ⁱ 

“We have responded to the COVID-19 pandemic with a comprehensive response plan to protect the health and safety of our employees as we continue to support vital oil and gas infrastructure around the world,” said Sivasankaran “Soma” Somasundaram, President and Chief Executive Officer. “Apergy’s businesses are classified as critical infrastructure; therefore, our manufacturing and field locations remain operational. Our response plan includes enacting social distancing policies, equipping employees with additional personal protective equipment, and following government and heath authority guidelines, including those of the Centers for Disease Control and Prevention and the World Health Organization. The health and safety of employees during this pandemic is paramount, and we are committed to taking all the necessary steps to do that. I want to thank all of our employees for their continued dedication and we are confident we will navigate this challenging environment responsibly and successfully”

“During the first quarter, our teams continued to execute well and support our customers against a challenging macro backdrop. We generated consolidated revenue of $261 million and adjusted EBITDA of $53 million for the quarter, which was within our guidance range. We also took proactive measures as part of a comprehensive contingency plan designed to maintain profitability and strong free cash flow despite the decline in oil prices from the OPEC+ actions in early March and reduced demand due to the COVID-19 pandemic. In response to continued difficult market conditions, we have increased the actions we are taking, and we now expect that our actions will result in $85 million of annualized cost savings, an increase of $20 million from the previous $65 million savings target announced. We will have completed most of the planned restructuring actions as we exit the second quarter, with the remaining actions completed by the middle of the third quarter. Additionally, we stand ready to take further actions as market conditions develop.

“We continue to maintain a strong financial position with liquidity of $298 million at the end of the first quarter, including $54 million in cash and available borrowing capacity of $244 million. During the first quarter we increased our available cash balance by generating free cash flow of $22 million, or 8% of revenue. Our performance during the quarter continues to demonstrate the profitability and cash generating capabilities of our portfolio and

contributed to the higher cash balance. We have a disciplined capital management process and we reacted swiftly to changing market dynamics. In preparation for settling transaction expenses associated with our planned merger with ChampionX, as well as in the spirit of proactive and prudent liquidity management, on April 24^th we increased our cash balance by drawing $125 million on our revolver leaving $119 million of available borrowing capacity.

“Due to the short-cycle nature of our business and recent global events, visibility is challenging. We are seeing meaningful sequential declines in our order rates, and we are prepared for market conditions to remain challenging throughout 2020, and potentially longer, as the shape of global oil demand recovery from the COVID-19 pandemic remains unclear. However, we are confident that we will be a long-term winner in the industry. We have taken and will continue to, take aggressive actions in response to market conditions. Consistent with our ‘top box’ value creation framework, we are focused on being an indispensable partner to our customers, delivering products that are critical to maintaining existing production, and continuing to deliver strong free cash flow.

“We are also excited by our future after our merger with ChampionX, which is on track for an expected close by the end of June. Integration planning is proceeding well and has confirmed our synergy targets. A key aspect of the strategic rationale for the combination is to create a stronger, more diversified, and more resilient production-focused global company. Financially, the combination immediately reduces leverage and the strong free cash flow of the combined company will support further deleveraging over time. We think this merger is exactly the type of smart strategic combination the industry needs in the face of challenging market conditions.” ⁱⁱ

Production & Automation Technologies

In the first quarter of 2020, Production & Automation Technologies revenue increased $1.9 million, or 1%, sequentially, driven by growth in North America, partially offset by lower international revenues due to the timing of rod lift sales in international markets. On a year-over-year basis, Production & Automation Technologies revenue decreased $17.5 million, or 8%, due to lower artificial lift and other production equipment revenue in North America, partially offset by higher international and digital revenue.

Revenue from digital products was $33.9 million in the first quarter of 2020, a decrease of $0.7 million, or 2%, compared to $34.6 million in the fourth quarter of 2019, and an increase of $2.6 million, or 8%, compared to $31.3 million in the first quarter of 2019.

In the first quarter of 2020, segment operating loss was $674.1 million, which includes a non-cash goodwill and long-lived asset impairment charge of $682.8 million. Adjusted segment EBITDA was $40.0 million, which increased $4.4 million sequentially, or 12%, due to cost reduction actions, productivity initiatives, and isolated charges incurred in the fourth quarter of 2019 that did not repeat. On a year-over-year basis, adjusted segment EBITDA decreased $3.0 million, or 7%, due to the lower volume, partially offset by strong cost discipline and productivity initiatives.

3

Drilling Technologies

In the first quarter of 2020, Drilling Technologies revenue increased by $11.8 million, or 27%, sequentially, driven by the completion of an inventory destocking cycle by our drill bit customers for polycrystalline diamond cutters in the fourth quarter of 2019, as well as a 10% increase in diamond bearing revenues, partially offset by lower U.S. and worldwide rig counts. On a year-over-year basis, Drilling Technologies revenue decreased $21.6 million, or 28%, due to the significant reduction in U.S. drilling activity and lower diamond bearing revenues.

In the first quarter of 2020, segment operating profit was $11.4 million, and adjusted segment EBITDA was $15.8 million. Sequentially adjusted segment EBITDA increased by $4.4 million, or 38%, due to the higher volumes. Year-over-year, adjusted segment EBITDA decreased by $13.5 million, or 46%, as a result of the lower volume, partially offset by aggressive direct and SG&A cost reductions.

Sequentially, the average worldwide rig count was approximately unchanged and the average U.S. rig count declined 4% as of the end of the quarter. On a year-over-year basis, the average worldwide and U.S. rig counts declined 11% and 25%, respectively, at the end of the quarter and this decline has accelerated in April.

2020 Capital Expenditure and Leased Asset Guidance

Given limited visibility and significant uncertainty in the oil and gas industry, Apergy will not be providing income statement guidance for the three months ended June 30, 2020. During 2020, we will maintain our focus on the continued implementation of cost reduction actions to preserve adjusted EBITDA margins and positive free cash flow.

We are restricting our capital expenditures to maintenance requirements only, and we expect our full year 2020 capital expenditures combined with investment in leased assets in the net cash from operating activities section of our consolidated statement of cash flows to be approximately $30 million.

About Non-GAAP Measures

In addition to financial results determined in accordance with generally accepted accounting principles in the United States (“GAAP”), this news release presents non-GAAP financial measures. Management believes that adjusted EBITDA, adjusted EBITDA margin, adjusted segment EBITDA, adjusted segment EBITDA margin, adjusted net income attributable to Apergy, adjusted diluted earnings per share attributable to Apergy, reflect the core operating results of our businesses and help facilitate comparisons of operating performance across periods. In addition, free cash flow and free cash flow to revenue ratio are used by management to measure our ability to generate positive cash flow for debt reduction and to support our strategic objectives, while adjusted working capital provides a meaningful measure of operational results by showing changes caused by revenue or our operational initiatives. The foregoing non-GAAP financial measures should be considered in addition to, not as a substitute for or superior to, other measures of financial performance prepared in accordance with GAAP. A reconciliation of these non-GAAP measures to the comparable GAAP measures is included in the accompanying financial tables.
