“AdvanSix delivered a strong fourth quarter to close out a dynamic year. 2018 began with a significant weather event, which the organization successfully managed through, demonstrating our resiliency and ability to perform in any environment. Throughout the year, we maintained our focus on safe and stable operations, captured the benefit of improved market-based pricing, and generated higher free cash flow. We initiated two high-return capital projects in 2018 driving future growth and cost saving benefits for sustained long-term performance," said Erin Kane, president and CEO of AdvanSix. "Further, our additional $75 million repurchase authorization reflects confidence in ongoing cash flow performance and provides us with flexibility as we continue to mature our capital allocation strategy."

Sales of $386.6 million in the quarter increased approximately 4% versus the prior year. Sales volume increased approximately 5% versus the prior year primarily due to high utilization rates at our manufacturing sites and the unfavorable impact of a planned plant turnaround in the fourth quarter of 2017. Pricing overall decreased 1% versus the prior year, including a 4% unfavorable impact from raw material pass-through pricing following cost decreases in benzene and propylene (inputs to cumene which is a key feedstock to our products). Market-based pricing was favorable by 3% compared to the prior year reflecting improved industry supply and demand dynamics in our ammonium sulfate, nylon, and caprolactam product lines, partially offset by softness in chemical intermediates due to the lengthening of acetone supply globally.

Sales by product line represented the following approximate percentage of our total sales:


	4Q 2018	4Q 2017	FY 2018	FY 2017
Nylon	27%	28%	28%	29%
Caprolactam	21%	20%	19%	19%
Ammonium Sulfate Fertilizer	21%	16%	20%	19%
Chemical Intermediates	31%	36%	33%	33%

EBITDA of $42.8 million in the quarter increased $4.0 million versus the prior year primarily due to the unfavorable impact of the planned plant turnaround in the fourth quarter of 2017 (approximately $20 million) and the benefit of higher market-based pricing, partially offset by increased manufacturing costs, a $6 million charge to bad debt expense related to a Brazilian fertilizer customer filing for judicial reorganization and a prior year $4.4 million non-cash LIFO inventory reserve adjustment. Fourth quarter 2018 results included an approximately $2.9 million benefit from business interruption insurance advances related to the 1Q18 weather event claim.

Earnings per share of $0.68 in the quarter decreased versus $2.31 in the prior year period. Fourth quarter 2017 results included an approximately $1.71 per share one-time net tax benefit primarily related to re-measurement of net deferred tax liability at a lower corporate tax rate.

Cash flow from operations of $45.7 million in the quarter increased $9.5 million versus the prior year primarily due to the favorable impact of changes in working capital and the one-time net tax benefit discussed above driving a decline in net income and offsetting increase in deferred taxes. Capital expenditures of $36.6 million in the quarter increased $17.3 million versus the prior year primarily due to an increase in spend on growth and cost savings projects.

Summary full year 2018 financial results for the Company are included below:

Full Year 2018 Highlights

•Sales up approximately 3% versus prior year, including 3% higher raw material pass-through pricing, 2% favorable impact of market-based pricing, and 2% lower volume

•EBITDA of $146.5 million, a decrease of $54.3 million versus the prior year; 1Q18 weather-related event resulted in an approximately $30 million unfavorable impact to pre-tax income

•Net Income of $66.2 million, a decrease of $80.5 million versus the prior year driven by the factors discussed above and an approximately $53 million one-time net tax benefit in the prior year primarily related to re-measurement of net deferred tax liability at a lower corporate tax rate

•Cash Flow from Operations of $173.4 million, an increase of $38.8 million versus the prior year

•Free Cash Flow of $64.2 million, an increase of $16.0 million versus the prior year

Outlook

•Expect strong nylon plant utilization rates to continue while navigating through more uncertain near-term auto and building/construction macro environment

•Ammonium sulfate fertilizer prices expected to increase seasonally; Expecting improved nitrogen fertilizer environment to continue through Spring planting season

•Expect challenging acetone industry conditions to continue; Filed antidumping duty petitions covering imports of acetone with the International Trade Commission and U.S. Department of Commerce

•Capital Expenditures expected to be $140 to $150 million for the full year 2019, including high-return growth and cost saving projects and an increase in maintenance spending due to the scope and timing of planned plant turnarounds

•Full year 2019 pre-tax income impact of planned plant turnarounds expected to be $35 to $40 million

“In 2019, we expect improved financial and operational performance. We're optimizing production output and maximizing higher value product mix, and we'll begin to see the benefits

of our investments in high-return capital projects in the second half of the year. Despite a more uncertain near-term macro environment and continued softness in North America acetone industry spreads, we expect strong plant utilization rates to continue. We're executing against our focused strategy and remain confident in our ability to deliver long-term value to our shareholders,” added Kane.

Free cash flow ⁽¹⁾	$	9,085	$	16,904	$	64,170	$	48,169

⁽¹⁾ Free cash flow is a non-GAAP measure defined as Net cash provided by operating activities less Expenditures for property, plant and equipment

The Company believes that this metric is useful to investors and management as a measure to evaluate our ability to generate cash flow from business operations and the impact that this cash flow has on our liquidity.

EBITDA margin ⁽³⁾	11.1%		10.5%		9.7%		13.6%

⁽²⁾ EBITDA is a non-GAAP measure defined as Net Income before Interest, Income Taxes, Depreciation and Amortization
⁽³⁾ EBITDA margin is defined as EBITDA divided by Sales

The Company believes these non-GAAP financial measures provide meaningful supplemental information as they are used by the Company’s management to evaluate the Company’s operating performance, enhance a reader’s understanding of the financial performance of the Company, and facilitate a better comparison among fiscal periods and performance relative to its competitors, as these non-GAAP measures exclude items that are not considered core to the Company’s operations.
