The Container Store Group, Inc. Announces Second Quarter Fiscal 2015 Financial Results

Company Reports 0.1% Comparable Store Sales Increase; Sees Traction from Growth Initiatives, with TCS Closets’ Impact on Comparable Store Sales Doubling from Last Quarter; Plans Spring 2016 Launch of Customer Financing Program

Coppell, TX — October 5, 2015 — The Container Store Group, Inc. (NYSE: TCS) (the “Company”), today announced financial results for the second quarter and year-to-date ended August 29, 2015.

·                  Comparable store sales for the second quarter of fiscal 2015 were up 0.1% compared to the second quarter of fiscal 2014.

·                  The result for consolidated net sales for the second quarter of fiscal 2015 was $195.5 million, up 1.2% compared to the second quarter of fiscal 2014 after converting the Elfa International AB portion of consolidated net sales from Swedish krona (“SEK”) to U.S. dollars.  Elfa International AB third-party net sales for the second quarter of fiscal 2015 were SEK 135.2 million, up 7.2% compared to the second quarter of fiscal 2014.  Converting Elfa International AB third-party net sales to U.S. dollars reduced the consolidated net sales results by 1.9% percent, from 3.1% to 1.2%, or $3.8 million for the second quarter of fiscal 2015 compared to the second quarter of fiscal 2014 using the prior year conversion rate for both periods.

·                  Consolidated net income per diluted share (EPS) was $0.06 for the second quarter of fiscal 2015, reflecting, as planned, approximately $0.02 per diluted share attributable to spend for key strategic initiatives.  This compares to consolidated adjusted net income per diluted share of $0.11 in the second quarter of fiscal 2014 (see GAAP/Non-GAAP reconciliation table at the end of this release).  Fiscal 2015 continues to serve as an investment year for the Company as it takes the necessary steps to properly and fully support employee training, customer service improvements and marketing for its strategic initiatives.  Accordingly, the Company believes the greatest impact of the initiatives to sales will come in 2016 and beyond.

·                  The Company is on track to achieve its targeted 12% square footage growth by opening a total of 10 stores for the 2015 fiscal year.  The Company opened two new stores and relocated one store in the second quarter of fiscal 2015, to end the quarter with 73 stores.

“Our sales performance in the second quarter exceeded our expectations with positive comparable store sales, a result of even more strategic customer engagement and service initiatives, coupled with the ‘snowballing effect’ of our major initiatives,” said Kip Tindell, Chairman and Chief Executive Officer.  “The benefit from TCS Closets to our comparable store sales more than doubled from the first quarter to second quarter of fiscal 2015.”

Tindell continued, “I am proud of the solid execution across our entire organization during the ongoing rollout of our major strategic initiatives, including TCS Closets and Contained Home.  With initiatives of this magnitude and complexity, we believe it is vitally important to make the appropriate investments in order to ensure their future success. We remain on track for the full rollout of our initiatives by the end of fiscal 2015, and with each market’s launch we continue to improve our visual displays, training and selling processes, allowing us to further leverage our investments to date.  We have streamlined the path to purchase options for TCS Closets, which has already increased our capacity and shortened the turnaround time for custom closet orders by approximately 28% from first quarter to second quarter of fiscal 2015.”

An evolution of the Company’s customer engagement strategy also continues, with even more compelling, relevant and strategic communications based on a customer’s individual purchase behavior and lifestyle.  These ongoing test and learn customer touch points are allowing the Company to further improve the effectiveness of its customer engagement efforts in order to maximize sales and profitability.

“Our intense and ongoing focus on solutions-based selling and the number of units sold in each transaction also continues to become more and more impactful and is another driver of our second quarter sales increase,” Tindell concluded.

·                  TCS Closets TM: The Company continues to be pleased with the rollout of its new custom closet collection, with the average ticket still exceeding $10,000 since launch — greatly surpassing the Company’s day-to-day average ticket of approximately $60.  To date, approximately 20% of TCS Closets customers are considered to be brand new customers, with 23% of TCS Closets customers purchasing more than one TCS Closet.  The new path to purchase, which leverages its expert in-store and call center salespeople to complement the services of the Contained Home in-home professional organizer, shortened the sales cycle by approximately 28% from first quarter to second quarter of fiscal 2015, while also increasing capacity.

TCS Closets was available in 61 stores, as planned, at the end of the second quarter.  The collection is on track to roll out to each new store upon its opening, and the below existing stores by the end of fiscal 2015:

Q3   9 stores in Philadelphia, Atlanta, Charlotte, Raleigh, Nashville, Little Rock and Minneapolis
Q4   3 stores in Seattle and Portland

·                  Contained HomeSM: The Company’s in-home organization service now has approximately 160 Contained Home organizers to date and satisfaction with the service remains high, with over 90% of customers saying they would recommend Contained Home to a friend.  Average ticket continues to exceed $2,500 program-to-date.  Contained Home was available in 61 stores, as planned, at the end of the second quarter and is also on track to roll out to each new store upon its opening, and the below existing stores by the end of fiscal 2015:

Q3   9 stores in Philadelphia, Atlanta, Charlotte, Raleigh, Nashville, Little Rock and Minneapolis
Q4   3 stores in Seattle and Portland

·                  POP! Perfectly Organized Perks®:  The Container Store’s customer engagement program has enrolled more than 2.6 million POP! Stars since launching in July 2014 and continues to add about 25,000 POP! Stars each week. Ongoing analysis of the program shows that customers who have been in the program for over one year have increased their shopping frequency on average by approximately one visit since they joined the program. This platform is the new way in which the Company communicates with and engages its customers.  It does so through personalized tips and product solutions most relevant to their individual lifestyle. They are enticed to shop and rewarded along the way with tailored communications including exclusive access, perks and events in order to deepen engagement and loyalty.

New stores

The Company’s new store performance continues to be very strong.  Over the past 3 years, as of the end of the second quarter fiscal 2015, the 17 new stores that were open for 12 months had an average Adjusted EBITDA margin of approximately 19% in their first year of operation.  Additionally, through myriad efficiencies, the Company has substantially reduced payroll associated with opening a new store, ultimately realizing an approximate 25% reduction in its grand opening expenses when comparing the average amount spent per new store opening in fiscal 2015 to fiscal 2014.  The Company is on track to meet its targeted 12% square footage growth for fiscal 2015.  It opened three new stores and relocated one store during the first half of the fiscal year to end the quarter with 73 stores.  Two additional stores have opened since the end of the second quarter and there are four stores currently under construction and scheduled to open in fiscal 2015:

·                  Opened September 12th — Milwaukee, WI (Mayfair Mall)

·                  Opened September 26th — Phoenix, AZ (The Shops at Town and Country)

·                  October 17th — Christiana, DE (Christiana Fashion Center)

·                  November 14th — Oxnard, CA (The Collection at River Park)

·                  January 30, 2016 — Sacramento, CA (Howe Bout Arden)

·                  February 20, 2016 — Alpharetta, GA (Avalon)

In addition to its major strategic initiatives, the Company continues to focus on shorter term, sales-growth opportunities. The Company just announced it has signed an agreement to partner with Synchrony Financial to implement a new customer financing program, with a planned launch in spring 2016.  The Company’s newly re-branded business-to-business sales function, Business Solutions: Your Dedicated Source for Storage and Organization Solutions for your Business, while still in its infancy, is growing at a rapid rate.  And the Company continues to focus on enhancements to its mobile and multi-channel shopping experience with improved search engine optimization, video content and community question and answer functionality, while also using its website to grow the brand with initiatives like the June 2015 launch of Container StoriesSM, its lifestyle blog.

Second Quarter 2015 Results

For the second quarter (thirteen weeks) ended August 29, 2015, on a consolidated basis:

·                  The result for consolidated net sales for the second quarter of fiscal 2015 was $195.5 million, up 1.2% compared to the second quarter of fiscal 2014 after converting the Elfa International AB portion of consolidated net sales from Swedish krona (“SEK”) to U.S. dollars.  Net sales in The Container Store retail business were $179.5 million, up 2.7% as compared to the second quarter of fiscal 2014, primarily due to new store sales. Elfa International AB third-party net sales for the second quarter of fiscal 2015 were SEK 135.2 million, up 7.2% compared to the second quarter of fiscal 2014.  Converting Elfa International AB third-party net sales to U.S. dollars reduced the consolidated net sales results by 1.9% percent, from 3.1% to 1.2%, or $3.8 million for the second quarter of fiscal 2015 compared to the second quarter of fiscal 2014 using the prior year conversion rate for both periods.

·                  Consolidated gross margin was 58.2%, a decline of 60 basis points compared to the second quarter of fiscal 2014. The Container Store retail business gross margin declined 140 basis points to 57.9%, largely due to the April 2015 introduction of everyday free shipping on orders over $75, a higher response to other promotional offers, and a higher mix of lower-margin service sales (i.e. installation and organization services) during the second quarter of fiscal 2015 as compared to the second quarter of fiscal 2014. This was partially offset by the impact of the stronger U.S. dollar. While the introduction of everyday free shipping on orders over $75 has reduced the gross margin rate, increased sales volumes associated with the strategy more than offset the related costs. Elfa International AB gross margin improved 340 basis points primarily due to improved production efficiency as a result of investments in automation, as well as a shift in sales mix. On a consolidated basis, gross margin declined as the decline in The Container Store retail business gross margin more than offset the improvement in Elfa International AB gross margin due to a larger percentage of net sales coming from The Container Store retail business.

·                  Consolidated selling, general and administrative expenses (“SG&A”) increased by 3.7% to $93.6 million from $90.3 million in the second quarter of fiscal 2014. SG&A as a percentage of net sales increased 120 basis points, primarily due to incremental expenses incurred at The Container Store retail business related to increased investment in store payroll for enhanced sales floor coverage and in the distribution center due to fulfillment of an increased number of orders shipped directly to customers, and expected costs incurred related to major initiatives. Fiscal 2015 continues to serve as an investment year for the Company as it takes the necessary steps to support its strategic initiatives.

·                  Consolidated net interest expense decreased to $4.2 million from $4.4 million in the second quarter of fiscal 2014.

·                  The effective tax rate for the second quarter of fiscal 2015 was 40.1%, as compared to 17.5% in the second quarter of fiscal 2014. The increase in the effective tax rate was primarily due to a $1.8 million reduction in tax expense recorded in fiscal 2014 primarily related to a refund of tax paid in a prior period, combined with a shift in the mix of projected domestic and foreign earnings.

·                  U.S. generally accepted accounting principles (“GAAP”) net income was $2.7 million, or $0.06 per diluted share, in the second quarter of fiscal 2015 compared to net income of $7.0 million, or $0.14 per diluted share, in the second quarter of fiscal 2014. Net income in the second quarter of fiscal 2014 includes a $0.03 tax benefit related to a refund of tax paid in a prior period.  Excluding the tax benefit, adjusted net income per diluted share in the second quarter of fiscal 2014 was $5.1 million, or $0.11 per diluted share (see GAAP/Non-GAAP reconciliation table at the end of this release).

·                  Consolidated adjusted EBITDA was $19.8 million compared to $23.4 million in the second quarter of fiscal 2014, (see GAAP/Non-GAAP reconciliation table).

For the year-to-date (twenty-six weeks) ended August 29, 2015, on a consolidated basis:

·                  The result for consolidated net sales was $365.3 million, down 0.4% compared to the year-to-date fiscal 2014 after converting the Elfa International AB portion of consolidated net sales from Swedish krona (“SEK”) to U.S. dollars.  Net sales in The Container Store retail business were $332.2 million, up 2.4% as compared to year-to-date fiscal 2014, primarily due to new store sales, which more than offset the comparable store sales decline of 0.3%. Elfa International AB third-party net sales were SEK 280.5 million, consistent with year-to-date fiscal 2014.  Converting Elfa International AB third-party net sales to U.S. dollars reduced the consolidated net sales results by 2.5% percent, from up 2.1% to down 0.4%, or $9.1 million for the first half of fiscal 2015 compared to the first half of fiscal 2014 using the prior year conversion rate for both periods.

·                  Consolidated gross margin was 58.3%, a decline of 20 basis points compared to year-to-date fiscal 2014. The Container Store retail business gross margin declined 80 basis points to 58.0%, largely due to the April 2015 introduction of everyday free shipping on orders over $75, a higher response to other promotional offers, and a growing mix of lower-margin service sales during the first half of fiscal 2015 as compared to the first half of fiscal 2014. This was partially offset by the impact of the stronger U.S. dollar. While the introduction of everyday free shipping on orders over $75 has reduced the gross margin rate, the increased sales volumes associated with the strategy more than offset the related costs. Elfa International AB gross margin improved 80 basis points primarily due to improved production efficiency as a result of investments in automation, as well as a shift in sales mix, partially offset by higher freight costs. On a consolidated basis, gross margin declined as the decline in The Container Store retail business gross margin more than offset the improvement in Elfa International AB gross margin due to a larger percentage of net sales coming from The Container Store retail business.

·                  Consolidated selling, general and administrative expenses (“SG&A”) increased by 3.5% to $187.5 million from $181.2 million in year-to-date fiscal 2014. SG&A as a percentage of net sales increased 190 basis points, primarily due to incremental expenses incurred at The Container Store retail business related to increased investment in store payroll for enhanced sales floor coverage and in the distribution center due to fulfillment of an increased number of orders shipped directly to customers, expected costs incurred related to major initiatives, and an increase in healthcare costs. Fiscal 2015 continues to serve as an investment year for the Company as it takes the necessary steps to support its strategic initiatives.

·                  Consolidated net interest expense decreased to $8.4 million from $8.7 million in year-to-date fiscal 2014.

·                  The effective tax rate was 32.6%, as compared to (15.5%) in year-to-date fiscal 2014. The increase in the effective tax rate was primarily due to a $1.8 million reduction in tax expense recorded in fiscal 2014 primarily related to a refund of tax paid in a prior period, the effects of a pre-tax loss in the first half of fiscal 2015, as well as a change in mix between projected domestic and foreign earnings.

·                  U.S. generally accepted accounting principles (“GAAP”) net loss was $2.5 million, or $0.05 per diluted share, in year-to-date fiscal 2015 compared net income of $3.4 million, or $0.07 per diluted share, in year-to-date fiscal 2014. Net income in year-to-date fiscal 2014 includes a tax benefit related to a refund of tax paid in a prior period.  Excluding the tax benefit, adjusted net income per diluted share in year-to-date fiscal 2014 was $1.5 million, or $0.03 per diluted share (see GAAP/Non-GAAP reconciliation table at the end of this release).

·                  Consolidated adjusted EBITDA was $24.5 million compared to $33.6 million in year-to-date fiscal 2014, (see GAAP/Non-GAAP reconciliation table).

Outlook

For fiscal 2015, the Company continues to expect consolidated net sales to be $800 to $815 million.  However, it is narrowing its outlook for change in comparable store sales for fiscal 2015 to -1% to 0% from the previously provided -2% to 0%.  Net income is still expected to be $0.30 to $0.38 per diluted share based on estimated diluted shares outstanding of 49 million. This assumes a tax rate of approximately 39% for the full year.

This outlook now incorporates approximately $5.5 million of expenses, or $0.07 per diluted share, associated with the implementation of the above outlined key strategic initiatives. The Company expects to make additional incremental expense investments, primarily payroll-related, to complete implementation of the key strategic initiatives in fiscal 2015, for an estimated increase of $1 million, or $0.01 compared to original Outlook.

Note Regarding Non-GAAP Information

This press release includes financial measures that are not calculated in accordance with GAAP, including adjusted net income (loss), adjusted net income (loss) per diluted common share, adjusted EBITDA and net sales after the conversion of Elfa International AB third-party net sales from Swedish krona to U.S. dollars using the prior year conversion rate. The Company believes the disclosure of net sales without the effects of currency exchange rate fluctuations helps investors understand the Company’s underlying performance. The Company has reconciled all non-GAAP financial measures apart from net sales adjusted for currency exchange rate fluctuations with the most directly comparable GAAP financial measures in a table accompanying this release. The Company believes that the non-GAAP financial measures used in this press release not only provide its management with comparable financial data for internal financial analysis but also provide meaningful supplemental information to investors. Specifically, these non-GAAP financial measures allow investors to better understand the performance of the Company’s business and facilitate a meaningful evaluation of its fiscal 2015 quarterly and annual results on a comparable basis with its fiscal 2014 quarterly and annual results. In evaluating these non-GAAP financial measures, investors should be aware that in the future the Company may incur expenses or be involved in transactions that are the same as or similar to some of the adjustments in this presentation. The Company’s presentation of non-GAAP financial measures should not be construed to imply that its future results will be unaffected by any such adjustments. The Company has provided this information as a means to evaluate the results of its ongoing operations. Other companies in the Company’s industry may calculate these items differently than it does. Each of these measures is not a measure of performance under GAAP and should not be considered as a substitute for the most directly comparable financial measures prepared in accordance with GAAP. Non-GAAP financial measures have limitations as analytical tools, and investors should not consider them in isolation or as a substitute for analysis of the Company’s results as reported under GAAP.
