TimkenSteel Announces Fourth-Quarter, Full-Year 2018 Results; Exceeds Guidance for Quarter

• Fourth-quarter net sales increased 19 percent year over year with improved product mix, higher prices and increased volume

• Company positioned to deliver earnings growth in 2019

CANTON, Ohio: February 20, 2019 - TimkenSteel (NYSE: TMST, timkensteel.com), a leader in customized alloy steel products and services, today reported fourth-quarter 2018 net sales of

$406 million and a net loss of $40 million or minus $0.89 per diluted share. In the same quarter last year, net sales were $341 million with a net loss of $34 million or minus $0.76 per diluted share. Adjusted EBITDA⁽¹⁾ for fourth-quarter 2018 was $26.7 million, an increase of $19 million over the same quarter last year.

For full-year 2018, net sales were $1.6 billion with a net loss of $32 million. In comparison, full-year 2017 net sales were $1.3 billion with a net loss of $44 million. Adjusted EBITDA⁽¹⁾ for full-year 2018 was $105 million, compared with $69 million in the prior year. The year-over-year increase in adjusted EBITDA was driven primarily by strong end-market demand, a richer product mix and improved price.

"We ended the year strong, delivering adjusted EBITDA and ship tons that exceeded our guidance for the quarter. Our performance was a culmination of the hard work by our entire team throughout 2018, during which we set several manufacturing and operational records, increased on-time delivery to over 90 percent by year-end, and achieved our safest year on record,” said Tim Timken, chairman, CEO and president. "In 2019, we plan to build on what we accomplished in the past year with continued improvement in product mix and pricing, as well as a focus on operational excellence to drive shareholder value."

FOURTH-QUARTER 2018 FINANCIAL SUMMARY

Fourth-quarter net sales increased $65 million or 19 percent year over year.

• Ship tons were 294,500, an increase of 3 percent over fourth-quarter 2017, due to strong operational execution and increased energy shipments.

• Net sales benefited from improved product mix, higher prices and increased volume.

• Surcharge revenue of $104 million represents a 34 percent increase from the prior-year quarter as a result of higher volumes and a rise in the No. 1 Busheling Index.

Fourth-quarter 2018 EBIT⁽¹⁾ was a loss of $35 million compared with a loss of $30 million for the same period a year ago. Adjusted EBIT⁽¹⁾ was $8.7 million, an improvement of $19 million from fourth-quarter 2017.

• Higher demand from energy markets along with lower OCTG billet volume and several price increases resulted in improved year-over-year product mix, price and volume.

• Manufacturing costs included the benefit of fixed-cost leverage and the timing of scheduled maintenance, with scheduled maintenance occurring in the third-quarter 2018 compared with the fourth-quarter 2017. These benefits were offset by inflation and the anticipated carryover cost from third-quarter 2018 production.

FIRST-QUARTER 2019 OUTLOOK

• Shipments are expected to be approximately 30,000 tons less than fourth-quarter 2018, primarily influenced by a reduction in OCTG billet demand.

• Product mix and price will be improved over fourth-quarter 2018.

• Raw material spread is expected to be a headwind due to a decline in the No. 1 Busheling Index compared with fourth-quarter 2018.

• Planned production downtime to balance inventory with short-term demand will result in lower fixed-cost leverage, along with maintenance and consumables headwinds.

• Net income (loss) is projected to be between $(4) million and $6 million.

• EBITDA⁽¹⁾ is projected to be between $20 million and $30 million.

FULL-YEAR 2019 ADDITIONAL INFORMATION

• Significant benefit from improved price and product mix is expected throughout 2019.

• Increased pension and post-retirement benefit expense of $13 million is expected (recorded in “other expense, net” on the consolidated income statement) due to lower 2018 pension asset returns and updated actuarial assumptions.

• 2019 capital spending is projected to be approximately $50 million.

The company will host a conference call at 9 a.m. ET on Thursday, Feb. 21, to discuss its financial performance with investors and securities analysts. The financial results and conference call materials will be available online at investors.timkensteel.com.
