Christopher J. Stephens
Senior Vice President & Chief Financial Officer at Sealed Air
Thank you, Ted, and good morning everyone. Let's start on slide 11 to review our quarterly and year-end net sales growth by segment and by region. In Q4, net sales were up 14% to $1.5 billion. In constant dollars, net sales were up 15% with 17% growth in food and 13% growth in Protective. The Americas and EMEA were both up double digits, with the Americas up 19% and EMEA up 13% while APAC was up 4% versus last year. In 2021, net sales were up 13% to $5.5 billion. In constant dollars, net sales were up 11% with 9% growth in food and 15% in Protective. Growth was led by the Americas and EMEA which were up 13% and 12% respectively, with APAC up 6% versus last year.
On Slide 12 you can see organic sales volumes and pricing trends by segment and by region. In Q4, overall volume growth was up 4% with favorable price of 12%. In 2021, volume growth and favorable price were both 6%. Let's start with volume trends and focus on Q4 performance and 2021 trends. In the quarter, food volumes were up 6% with growth across all regions. Americas up 5%, the EMEA up 10%, and APAC up 6%. Protective volumes were up 1% led by EMEA with 7% growth, flattened Americas, and APAC declined 4%. We experienced accelerating volume in Food in the second half with higher sales in automation and growth in materials as foodservice continued to recover and retail demand remained strong. Protective volume surged in the first half of 2021 on the heels of 2020 industrial shutdowns and growth in fulfillment around the world, particularly in EMEA. We faced tougher comps in the second half of 2021. However fulfillment automation sales were up and industrial demand was favorable. Starting in Q2 2021 in response to inflationary pressures, we accelerated pricing actions. Q4 price was favorable 12% with Protective at 13% and Food at 11%. For the full year 2021, we realized nearly $300 million in price of which more than half was realized in Q4 as a result of timing of pricing actions and formula pass-throughs. Given ongoing inflationary environment, we will be announcing additional price increases with care. These increases will vary based on region and product offering, and will average between 5% and 10%. We will work directly with our customers to meet increased demand and help them drive productivity and operational savings.
On Slide 13, we present our consolidated sales and adjusted EBITDA walks. Having already discussed sales, let me comment on our Q4 and full year adjusted EBITDA performance. Q4 adjusted EBITDA of $330 million up 18% compared to last year, with margins of 21.5%, up 70 basis points. Full-year adjusted EBITDA of $1.132 billion was up 8% compared to 2020 with margins of 20.4%, down 100 basis points. Higher volume contributed $23 million to Q4 adjusted EBITDA. Full year volume contributed $109 million to adjusted EBITDA. For the first time since Q3 2020 price cost spread was favorable in the quarter contributing $36 million to earnings. In 2021, price cost spread was unfavorable $37 million. Reinvent SEE benefits totaled $21 million in Q4 and $64 million in 2021. Operating costs include labor and other non-raw material cost inflation of about $20 million in Q4, which compares to $13 million in the same period a year ago and $69 million for the full year, which is up from $52 million in 2020. Adjusted earnings per diluted share in Q4 was $1.12 compared to $0.89 in Q4 2020. In 2021 we delivered adjusted EPS of $3.55 compared to $3.19 in 2020, an increase of 11%. Our adjusted tax rate was 26% compared to 24.5% in 2020. Our weighted average diluted shares outstanding in 2020 were $152 million compared to $156 million given we were an active buyer of our stock throughout the year purchasing 7.9 million shares for $403 million or approximately $51 per share. At year-end 2021, we had $896 million remaining under our authorized repurchase program.
Turning to slide 14, here we provide an update on Reinvent SEE. We achieved $64 million of benefits in 2021 bringing the cumulative benefits of our Reinvent SEE program to $354 million. Cash payments associated with Reinvent SEE were $28 million in 2021 and $193 million since the start of the program. To complete this program, we anticipate $20 million to $25 million in cash payments in 2022, half of which was carryover from 2021. We anticipate $60 million of productivity gains in 2022, of which approximately 1/3 is coming from Reinvent SEE initiatives, remaining 2/3 is our SEE Operating Engine, which is designed to drive continuous productivity improvements. With that said, inflationary pressures coupled with cost associated with supply disruptions are expected to continue. The combination of volume growth, pricing and SEE Operating Engine productivity gains are expected to mitigate these headwinds in 2022.
Turning to segment results on Slide 15 starting with Food, my comments will focus on our Q4 results. In Q4, Food net sales of $877 million were up 17% in constant dollars. Volume growth of 6% was led by double-digit growth in automation and strong growth in materials. Adjusted EBITDA of $204 million in Q4 increased 20% compared to last year with margins at 23.3% up 90 basis points. Higher volumes, pricing and productivity gains offset elevated costs. On Slide 16, we highlight Protective segment results. Net sales increased 14% on an organic basis to $655 million. Volume in the quarter was up 1% as we face tougher comps and managed through supply disruptions. Adjusted EBITDA of $126 million increased 10% in Q4 with margins at 19.3% down 40 basis points versus last year.
Now let's turn to free cash flow on Slide 17. In 2021, we generated $497 million of free cash flow relative to the same period last year, higher earnings and lower restructuring and interest payments were offset by working capital needs and incremental capex investments to support strong growth. On Slide 18, we are by our purpose driven capital allocation strategy focused on creating economic value. We maintain a strong balance sheet while driving attractive returns on invested capital and supporting profitable growth initiatives. We are focusing our capex on touchless automation, digital and sustainability. We are expanding our capacity and equipment to align with customer demand and support continued growth. We are investing in smart packaging and digital printing and see opportunities to expand our presence in attractive growth markets and geographies. We are managing our portfolio with the discipline to ensure alignment with our growth strategy.
Let's turn to Slide 19 to review our 2022 outlook. For net sales, we estimate $5.8 billion to $6 billion, an increase of 5% to 8%. Our organic growth forecast is 7% to 11% of which at the midpoint assumes approximately 3% volume and approximately 6% interest. We anticipate adjusted EBITDA to be in the range of $1.2 billion to point $1.24 billion. Adjusted EBITDA is expected to grow 6% to 10% and implies an EBITDA margin of approximately 21%. For adjusted EPS, we expect to be in the range of $3.95 to $4.15. This assumes depreciation and amortization of approximately $245 million and adjusted effective tax rate of approximately 26%, net interest expense of approximately $155 million and approximately a $150 million shares outstanding. And lastly, our outlook for free cash flow is expected to be in the range of $510 million to $550 million. We are increasing capex $240 million to $260 million to increase capacity to support growth initiatives. For cash tax payments, we anticipate to pay $205 million to $215 million in 2022 reflecting expected earnings growth, $17 million tax payments on the gain from sale of Reflectix, and approximately $30 million impact related to the R&D provision requiring R&D expenses to be deducted over five years versus the prior immediate expensing allowance. Additionally, as previously disclosed, our 2021 cash tax payments were reduced by approximately $24 million refund associated with the retroactive application of the revised US GILTI regulations. We are executing on our growth strategy, driving productivity and cash generation, and aligning our business around the SEE operating model. This is reflected in our 2022 outlook for sales, earnings and cash flow. To fuel our engine and drive accelerated growth beyond 2022, we are increasing our capex and R&D investments for innovation and automation. We have a strong balance sheet and we will continue to focus on generating attractive returns on invested capital. With that, let me now pass the call back to Ted for closing remarks. Ted?
