FOR IMMEDIATE RELEASE

Hexion Inc. Announces Third Quarter 2017 Results

Third Quarter 2017 Highlights

• Net sales of $914 million, a 12% increase versus prior year

• Net loss of $70 million

• Segment EBITDA of $96 million; adjusted for the impact of hurricanes, Segment EBITDA totaled $102 million, or a 9% decrease

• Announced a new $40 million cost reduction program

• Total liquidity as of September 30, 2017 of $310 million

COLUMBUS, Ohio - (November 14, 2017) - Hexion Inc. (“Hexion” or the “Company”) today announced results for the third quarter ended September 30, 2017.

“Hexion posted strong topline sales growth of 12% and volume gains of 9%, respectively, in the third quarter of 2017,” said Craig A. Rogerson, Chairman, President and CEO. “Our Segment EBITDA reflected continued year-over-year gains in our base epoxy resins, North American forest products resins, and global formaldehyde businesses offset by challenges associated with the hurricanes and continued weakness in global wind energy demand. We saw sequential profitability growth in our specialty epoxy resins business driven by strong growth in our waterborne coatings business and stable wind energy volumes. In addition, we continue to position the Company for profitable growth by strategically optimizing our cost structure and investing in our specialty portfolio.”

Mr. Rogerson added: “We were pleased to complete our Edmonton research and development facility expansion, which is focused on developing next generation forest product resins as we continue to strategically invest in our technology infrastructure. Finally, we expect to deliver year-over-year EBITDA growth and generate solid levels of free cash flow in the fourth quarter.”

Third Quarter 2017 Results

Net Sales. Net sales for the quarter ended September 30, 2017 were $914 million, an increase of 12% compared with $819 million in the prior year period. The increase in reported net sales was primarily driven by the pass-through of higher raw material costs and volume gains in oilfield proppants, base epoxy resins and North American forest product resins and formaldehyde businesses.

Segment EBITDA. Segment EBITDA for the quarter ended September 30, 2017 was $96 million, a decrease of 14% compared with the prior year period. Adjusted for the $6 million negative impact of hurricanes, Segment EBITDA totaled $102 million, or a decrease of 9% compared to the prior year. Third quarter 2017 results were driven by growth in our North American forest product resins and formaldehyde businesses, as well as improvements in base epoxy resins and oilfield proppants, which was offset by a year-over-year decline in the specialty epoxy resins business driven by destocking and competitive pressures in our global wind energy business. In addition, the Company benefited from insurance proceeds in the prior year period related to its Versatic™ Acids and Derivatives business that did not reoccur in the third quarter of 2017.

Global Restructuring Programs

In the first nine months of 2017, the Company achieved approximately $20 million of total in-process cost savings. As part of its ongoing commitment to optimize its cost structure and further streamline the organization, Hexion has identified approximately $40 million in additional structural cost savings. The Company remains committed to redeploying portions of its cost savings into strategic growth initiatives, such as its recently completed Edmonton research and development expansion and additional waterborne coatings capacity. With the addition of the new cost savings program, Hexion had $54 million of total in-process cost savings, which it expects to be achieved over the next 12 to 18 months.

Segment Results

Following are net sales and Segment EBITDA by reportable segment for the three and nine months ended September 30, 2017 and 2016. See “Non-U.S. GAAP Measures” for further information regarding Segment EBITDA and a reconciliation of net loss to Segment EBITDA.

Liquidity and Capital Resources

At September 30, 2017, Hexion had total debt of approximately $3.7 billion compared to $3.5 billion at December 31, 2016. In addition, at September 30, 2017, the Company had $310 million in liquidity comprised of $100 million of unrestricted cash and cash equivalents, $188 million of borrowings available under the Company’s senior secured asset-based revolving credit facility (the “ABL Facility”) and $22 million of time drafts and availability under credit facilities at certain international subsidiaries. Hexion expects to have adequate liquidity to fund its ongoing operations for the next twelve months from cash on its balance sheet, cash flows provided by operating activities and amounts available for borrowings under its credit facilities.

Covenant Compliance

The instruments that govern the Company’s indebtedness contain, among other provisions, restrictive covenants regarding indebtedness (including an Adjusted EBITDA to Fixed Charges ratio incurrence test), dividends and distributions, mergers and acquisitions, asset sales, affiliate transactions and capital expenditures.

The indentures that govern the Company’s 6.625% First-Priority Senior Secured Notes, 10.00% First-Priority Senior Secured Notes, 10.375% First-Priority Senior Secured Notes, 13.75% Senior Secured Notes and 9.00% Second-Priority Senior Secured Notes (collectively, the “Secured Indentures”) contain an Adjusted EBITDA to Fixed Charges ratio incurrence test which may restrict our ability to take certain actions such as incurring additional debt or making acquisitions if the Company is unable to meet this ratio (measured on a last twelve months, or LTM, basis) of at least 2.0:1. The Adjusted EBITDA to Fixed Charges ratio under the Secured Indentures is generally defined as the ratio of (a) Adjusted EBITDA to (b) net interest expense excluding the amortization or write-off of deferred financing costs, each measured on a LTM basis. See “Non-U.S. GAAP Measures” for further information regarding Adjusted EBITDA and Schedule 5 to the release for a calculation of the Adjusted EBITDA to Fixed Charges ratio.

The Company’s ABL Facility does not have any financial maintenance covenant other than a minimum Fixed Charge Coverage Ratio of 1.0 to 1.0 that would only apply if the Company’s availability under the ABL Facility at any time is less than the greater of (a) $35 million and (b) 12.5% of the lesser of the borrowing base and the total ABL Facility commitments at such time. The Fixed Charge Coverage Ratio under the credit agreement governing the ABL Facility is generally defined as the ratio of (a) Adjusted EBITDA minus non-financed capital expenditures and cash taxes to (b) debt service plus cash interest expense plus certain restricted payments, each measured on an LTM basis. At September 30, 2017, the Company’s availability under the ABL Facility exceeded such levels; therefore, the minimum fixed charge coverage ratio did not apply.

Non-U.S. GAAP Measures

Segment EBITDA is defined as EBITDA adjusted to exclude certain non-cash and non-recurring expenses. Segment EBITDA is an important measure used by the Company's senior management and board of directors to evaluate operating results and allocate capital resources among segments. Corporate and Other primarily represents certain corporate, general and administrative expenses that are not allocated to the segments. Segment EBITDA should not be considered a substitute for net loss or other results reported in accordance with U.S. GAAP. Segment EBITDA may not be comparable to similarly titled measures reported by other companies. See Schedule 4 to this release for reconciliation of net loss to Segment EBITDA.

Adjusted EBITDA is defined as EBITDA adjusted for certain non-cash and certain non-recurring items and other adjustments calculated on a pro forma basis, including the expected future cost savings from business optimization programs or other programs and the expected future impact of acquisitions, in each case as determined under the governing debt instrument. As the Company is highly leveraged, it believes that including the supplemental adjustments that are made to calculate Adjusted EBITDA provides additional information to investors about the Company’s ability to comply with its financial covenants and to obtain additional debt in the future. Adjusted EBITDA and Fixed Charges are not defined terms under U.S. GAAP. Adjusted EBITDA is not a measure of financial condition, liquidity or profitability, and should not be considered as an alternative to net loss determined in accordance with U.S. GAAP or operating cash flows determined in accordance with U.S. GAAP. Additionally, Adjusted EBITDA is not intended to be a measure of free cash flow for management’s discretionary use, as it does not take into account certain items such as interest and principal payments on our indebtedness, depreciation and amortization expense (because the Company uses capital assets, depreciation and amortization expense is a necessary element of our costs and ability to generate revenue), working capital needs, tax payments (because the payment of taxes is part of our operations, it is a necessary element of our costs and ability to operate), non-recurring expenses and capital expenditures. Fixed Charges under the Secured Indentures should not be considered an alternative to interest expense. See Schedule 5 to this release for reconciliation of net loss to Adjusted EBITDA and the Fixed Charges Ratio.

Ratio of Adjusted EBITDA to Fixed Charges (6)	1.35

(1) Primarily represents headcount reduction expenses and plant rationalization costs related to cost reduction programs, termination costs and other costs associated with business realignments, as well as environmental liabilities related to closed sites.

(2) Represents non-cash losses resulting from pension and postretirement benefit plan liability remeasurements.

(3) Primarily includes employee retention program costs, certain professional fees related to strategic projects and legacy sites, business optimization expenses and management fees.

(4) Represents pro forma impact of in-process cost reduction programs savings. Cost reduction program savings represent the unrealized headcount reduction savings and plant rationalization savings related to cost reduction programs and other unrealized savings associated with the Company’s business realignments activities, and represent our estimate of the unrealized savings from such initiatives that would have been realized had the related actions been completed at the beginning of the LTM period. The savings are calculated based on actual costs of exiting headcount and elimination or reduction of site costs.

(5) Reflects pro forma interest expense based on interest rates at September 30, 2017, as if the refinancing transactions in February 2017 and May 2017 had taken place at the beginning of the period.

(6) The Company’s ability to incur additional indebtedness, among other actions, is restricted under the Secured Indentures, unless the Company has an Adjusted EBITDA to Fixed Charges ratio of at least 2.0 to 1.0. As of September 30, 2017, we did not satisfy this test. As a result, we are subject to restrictions on our ability to incur additional indebtedness and to make investments; however, there are exceptions to these restrictions, including exceptions that permit indebtedness under our ABL Facility (available borrowings of which were $188 at September 30, 2017).
