Cornerstone building brands announces fourth-quarter and full-year 2020 results; expects strong growth in 2021
Cary, n.c.--(business wire)--cornerstone building brands, inc. (nyse: cnr) (the “company”), the largest manufacturer of exterior building products, today reported fourth-quarter 2020 net sales of $1,191.4 million and net income of $1.9 million or one cent per diluted share. this compares with net sales of $1,244.4 million and net income of $1.9 million or two cents per diluted share in the same quarter last year. adjusted ebitda1 for the fourth quarter of 2020 was $158.1 million or 13.3 percent of net sales, an improvement of 40 basis points from the same pro forma period a year ago, with 5 percent fewer ship days. the improvement was primarily due to effective structural cost reductions and better price/mix, partially offset by the impacts from lower non-residential demand. these results represent the seventh consecutive quarter of year-over-year adjusted ebitda1 margin expansion for the company. “we delivered strong fourth-quarter results, rounding out a year of record performance despite a challenging market environment,” said james s. metcalf, chairman and chief executive officer. “the resilience of our business model and strength of our dedicated team helped us deliver on our strategic priorities. i am proud of the cornerstone building brands team, which is made up of people from many backgrounds, each unique, and valued as part of our organization.” 2020 full year results and highlights net sales for 2020 were $4,617.4 million, 5.6 percent lower than in 2019. the decline was primarily driven by lower end market demand across all segments as a result of the covid-19 pandemic. loss from operations was $266.5 million, including a non-cash, pre-tax goodwill impairment accounting adjustment of $503.2 million. pro forma net sales1 were $4,625.7 million, a 6.5 percent decrease over prior year. pro forma adjusted ebitda1 for 2020 was $608.7 million or 13.2 percent of pro forma net sales1, an improvement of 2.6 percent or 120 basis points from the same pro forma period a year ago. the improvement was due to structural cost reductions, effective near-term expense management, and strong price/mix, net of inflation partially offset by the impacts from lower demand and shift in product mix as a result of the covid-19 pandemic. “our focus on our customer partnerships, expanding our product offerings and developing innovative solutions, positions us to expand our market leadership as residential markets continue their strong recovery.” metcalf continued. “moving forward, we will continue to execute on our priorities which include maintaining price discipline, driving operational excellence and investing in growth opportunities to deliver enhanced profitability and value to our stakeholders.” segment results versus prior year all segments delivered consecutive margin expansion over the prior year as a result of the quick and effective management of near-term expenses and acceleration of the company's strategy to permanently improve its highly variable cost structure. due to the timing of the company’s fiscal calendar, the fourth quarter of 2020 had three fewer ship days than the fourth quarter of 2019, which was approximately 5 percent less ship days. windows segment net sales for the quarter were $511.6 million, an increase of 3.2 percent from the prior-year quarter. effective price discipline coupled with volume leverage on higher demand from both distribution and retail channels supporting single family new home construction and repair and remodel were the primary drivers of the increase. adjusted ebitda1 was $61.6 million or 12.0 percent of net sales, an improvement of 20 basis points. for the full year, adjusted ebitda margin1 improved 140 basis points, while net sales were 2.1 percent lower. siding segment net sales for the quarter were $293.8 million an increase of 4.4 percent versus the pro forma1 fourth-quarter 2019. adjusted ebitda1 was $62.1 million or 21.1 percent of net sales, an improvement of 180 basis points. for the full year, pro forma adjusted ebitda margin1 improved 220 basis points, while pro forma net sales1 were 1.8 percent lower than in the prior year. effective price discipline coupled with cost management contributed to the favorable year-over-year variances. commercial segment net sales for the quarter were $386.0 million, a decrease of 19.2 percent from the prior-year quarter. adjusted ebitda1 was $61.7 million or 16.0 percent of net sales, an improvement of 20 basis points. for the full year, adjusted ebitda margin1 improved 60 basis points, while net sales were 14.2 percent lower. delays in construction activity and shifts in product mix toward less complex projects because of the impact of the covid-19 pandemic were more than offset by effective management of price with declining steel costs, and execution of cost savings initiatives. balance sheet and liquidity the company generated strong cash flow in 2020, with cash from operations of $308.4 million, a cash generation improvement of $78.8 million over 2019. capital expenditures were $81.9 million, with approximately 50 percent invested in innovative product offerings and process automation that are expected to generate profitable growth in the future. free cash flow2 of $226.6 million was an increase of 108.8 percent over 2019. the improvement was primarily driven by lower cash interest expenses, net cash tax benefits from the cares act and other covid-19 related government stimulus programs, and reduced capital spend. during the year, the company issued $500 million of senior unsecured notes due january 2029 bearing interest at 6.125% per year. the proceeds were used to repay debt under the asset-based revolving credit facility and cash flow revolver, and to pay transaction fees. the transaction improved liquidity, strengthened the company’s financial flexibility, and advanced our deleveraging strategy. the company ended the year with approximately $674 million of unrestricted cash on hand and $1,317 million of liquidity. additionally, the net debt leverage ratio1 improved to 4.9x at the end of 2020 compared with 5.3x at the end of 2019. outlook first-quarter 2021 guidance the first quarter of fiscal 2021 will have three fewer ship days; 64 ship days as compared to 67 ship days in the first quarter of 2020 the company expects net sales to be between $1,195 million and $1,240 million as a result of: strong single-family housing end-market momentum; expect double digit growth in residential businesses over prior year improving non-residential end-markets strong single-family housing end-market momentum; expect double digit growth in residential businesses over prior year improving non-residential end-markets gross profit is anticipated to be between $250 million and $265 million. adjusted ebitda1 is expected to be between $110 million and $125 million based on the following assumption: disciplined price leadership to more than offset increasing raw material costs disciplined price leadership to more than offset increasing raw material costs additional fiscal year 2021 guidance cost savings initiatives of $75 million to $80 million return of near-term costs of approximately $20 million to $30

non-gaap financial measures this press release includes certain “non-gaap financial measures” as defined under the securities exchange act of 1934 and in accordance with regulation g. management believes the use of such non-gaap financial measures assists investors in understanding the ongoing operating performance of the company by presenting the financial results between periods on a more comparable basis. such non-gaap financial measures should not be construed as an alternative to reported results determined in accordance with u.s. gaap. we have included reconciliations of these non-gaap financial measures to the most directly comparable financial measures calculated and provided in accordance with u.s. gaap at the end of this release. a reconciliation of the forecasted range for adjusted ebitda for the first quarter of 2021 is not included in this release due to the number of variables in the projected range and because we are currently unable to quantify accurately certain amounts that would be required to be included in the gaap measure or the individual adjustments for such reconciliation. in addition, we believe such reconciliation would imply a degree of precision that would be confusing or misleading to investors. cornerstone building brands, inc. consolidated statements of operations (in thousands, except per share data) (unaudited) three months
