2018 Second Quarter Financial Highlights

All comparisons below (which are generally indicated by words such as “increased,” “decreased,” “remained,” or “compared to”), unless otherwise noted, are comparing the quarter ended June 30, 2018 with the quarter ended June 30, 2017.


•	Consolidated net sales of $308.0 million increased 17.1% from $263.0 million.


◦	North America net sales of $259.8 million increased 20.4% from $215.7 million, primarily due to increases in sales volume. Canada's net sales were positively affected by foreign currency translation.

◦

Europe net sales of $45.8 million increased 1.2% from $45.2 million, primarily due to approximately $2.7 million of positive foreign currency translations resulting from Europe currencies strengthening against the United States dollar, as well as increases in sales volume. Net sales were partly offset by reduced sales volume due to the late 2017 sale of Gbo Fastening Systems' Poland and Romania subsidiaries (acquired in January 2017), which contributed $4.3 million in net sales for the second quarter of 2017.


•	Consolidated gross profit of $141.5 million increased 14.5% from $123.5 million. Gross profit margin decreased to 45.9% from 47.0% mostly due to increased material costs.


◦	North America gross profit margin decreased to 47.6% from 49.4%.


◦	Europe gross profit margin increased to 38.2% from 37.2%.


•	Consolidated income from operations of $60.7 million increased 34.6% from $45.1 million. Income from operations for the second quarter of 2018 included severance expenses of $2.2 million recorded for the quarter and increased SAP related expenses of $1.1 million. Consolidated operating profit margin increased to 19.7% from 17.2%.


◦	North America income from operations of $58.5 million, which included severance costs of $0.7 million recorded in cost of sales, increased 39.2% from $42.0 million.

◦

Europe income from operations of $2.8 million, which included severance costs of $1.6 million recorded in general and administrative expense and increased SAP related costs of $0.5 million, decreased 31.2% from $4.1 million. Europe income from operations for the second quarter of 2018 was negatively impacted by the late 2017 sale of Gbo Fastening Systems' Poland and Romania subsidiaries (acquired in January 2017), which subsidiaries contributed $0.4 million in income from operations for the second quarter of 2017.


•	The Company's effective income tax rate decreased to 27.2% from 37.2%, primarily due to the U.S. Tax Cuts and Jobs Act of 2017, which reduced the United States statutory federal corporate tax rate from 35% to 21%.


•	Consolidated net income was $44.1 million, or $0.94 per diluted share of the Company's common stock, compared to net income of $28.2 million, or $0.59 per diluted share of the Company's common stock.

Year-to-Date (6-month) 2018 Financial Highlights

All comparisons below (which are generally indicated by words such as “increased,” “decreased,” “remained,” or “compared to”), unless otherwise noted, are comparing the six months ended June 30, 2018 with the six months ended June 30, 2017.


•	Consolidated net sales of $552.8 million increased 14.5% from $482.9 million.


◦	North America net sales of $466.0 million increased 16.7% from $399.5 million, primarily due to increases in sales volume. Canada's net sales were positively affected by foreign currency translation.

◦

Europe net sales of $82.1 million increased 3.1% from $79.6 million, primarily due to approximately $7.1 million of positive foreign currency translations resulting from Europe currencies strengthening against the United States dollar. Net sales were partly offset by reduced sales volume due to the late 2017 sale of Gbo Fastening Systems' Poland and Romania subsidiaries (acquired in January 2017), which contributed $7.3 million in net sales for the six months ended June 30, 2017. In local currencies, Europe net sales increased primarily due to increased sales volumes and average net sales unit prices.


•	Consolidated gross profit of $250.0 million increased 11.8% from $223.7 million. Gross profit as a percentage of net sales decreased to 45.2% from 46.3%.


◦	North America gross profit as a percentage of net sales decreased to 47.3% from 48.9%.


◦	Europe gross profit as a percentage of net sales increased to 35.4% from 35.0%.

•

Consolidated income from operations of $93.5 million increased 38.0% from $67.8 million.

Europe income from operations for the six months ended June 30, 2018 was negatively impacted by the late 2017 sale of Gbo Fastening Systems' Poland and Romania subsidiaries (acquired in January 2017), which subsidiaries contributed $0.6 million in income from operations for the six months ended June 30, 2017.

•

The Company's effective income tax rate decreased to 25.4% from 32.2%, primarily due to the U.S. Tax Cuts and Jobs Act of 2017, which reduced the United States statutory federal corporate tax rate from 35% to 21%. The effective income tax rate for the six months ended June 30, 2017 was also reduced by a nonrecurring gain on a bargain purchase related to the Gbo Fastening Systems acquisition, which was not taxable.

•

Consolidated net income was $69.5 million, or $1.48 per diluted share of the Company's common stock, compared to net income of $51.3 million, or $1.07 per diluted share of the Company's common stock. The $51.3 million consolidated net income for the six months ended June 30, 2017 included an $8.4 million nonrecurring gain on a bargain purchase of a business, which increased diluted earnings per share for the same period by $0.18.


•	Cash flow provided by operating activities increased approximately $47.6 million to $55.4 million from $7.7 million.


•	Cash flow used in investing activities decreased approximately $39.3 million to $17.0 million from $56.4 million. Capital expenditures were $19.0 million compared to $30.2 million.

Management Commentary

“We had an excellent second quarter with our net sales up 17% year-over-year to $308.0 million,” commented Karen Colonias, President and Chief Executive Officer of Simpson Manufacturing Co., Inc. “Positive demand trends, supported by strong North American housing starts, resulted in high growth in sales volume throughout almost all areas of our company. We do not believe our growth in second quarter sales volume was a result of significant pre-buying activity in advance of the 11.5% average price increase for a majority of our U.S. wood connector products which became effective on July 1, 2018. So far in the third quarter, demand remains strong.”

Mrs. Colonias continued, “During the quarter, we continued to execute against our key operating initiatives, many of which stem from the 2020 Plan we unveiled three quarters ago to provide more clarity into our longer-term strategy and financial objectives. I am pleased to reiterate our 2020 financial targets as part of this plan today. In addition, we made important headway in the second quarter with our third-party consultants in regard to identifying improvements to our cost structure and working capital and these improvements are expected to be realized in the future. We also continued to concentrate on growing our market share and improving our technologies and systems to provide best-in-class service to our customers, an important part of our longstanding, trusted reputation, and what sets the Simpson Strong-Tie brand apart. We remain confident in our ability to execute based on current market conditions and believe our key objectives will provide additional runway to continue returning capital to shareholders.”

Corporate Developments


•	Effective July 1, 2018, the Company increased prices on a majority of its wood connector products sold in the United States by an average of 11.5% in an effort to offset rising raw materials costs.


•	On July 26, 2018, the Company’s Board of Directors declared a quarterly cash dividend of $0.22 per share. The dividend will be payable on October 25, 2018 to the Company shareholders of record as of October 4, 2018.

•

During the first two quarters of 2018, the Company received and repurchased 627,271 shares of the Company's common stock, including 445,100 shares of its common stock repurchased in the open market at an average price of $57.15 per share, for a total of $25.4 million and 182,171 shares of its common stock received as the final delivery of a $50.0 million accelerated share repurchase program initiated in December 2017. As a result, as of June 30, 2018, approximately $126.1 million remained available for share repurchase through December 31, 2018 under the Company's previously announced $275.0 million share repurchase authorization.

Business Outlook

Subject to changing economic conditions, future events and circumstances:


•	The Company currently believes the market price for steel will continue to be volatile during the third quarter of 2018, due to uncertainty related to steel tariffs.


•	The Company estimates that its 2018 full-year gross profit margin will be between approximately 45% to 46%.

•

The Company estimates that its 2018 full-year effective tax rate will be between approximately 26% to 27%, including both federal and state income tax rates. The ultimate impact of the Tax Cuts and Jobs Act signed into law in 2017 and the Company's 2018 effective tax rate may differ materially from the Company’s estimates due to changes in the interpretations and assumptions made by the Company as well as additional regulatory guidance that may be issued and actions the Company may take as a result of the Tax Cuts and Jobs Act, such as cash repatriation to the United States, if any. The Company will continue to assess the expected impact of the new tax law and provide additional disclosures at appropriate times.
