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

Company Exceeds Outlook on Comparable Store Sales and EPS, Maintains Targets for Fiscal 2015

Key Strategic Initiatives on Track for Full Rollout in 2015 and Having a Notable Impact

Dallas, TX — July 7, 2015 — The Container Store Group, Inc. (NYSE: TCS) (the “Company”), today announced financial results for the first quarter of fiscal 2015 ended May 30, 2015.

·                  Company comparable store sales for the first quarter of fiscal 2015 were down 0.9% compared to first quarter of fiscal 2014, exceeding the Company’s stated outlook for the first quarter of down 3% to 4%. Excluding lost sales due to West Coast port delays, estimated at 1 percentage point, comparable store sales would have been approximately flat for the quarter.

·                  Consolidated net sales were $169.8 million, down 2.1%; however, consolidated net sales were up 0.9% after converting Elfa’s net sales results from Swedish krona to U.S. dollars using the prior year’s conversion rate for both periods. Due to the strengthening of the U.S. dollar against the Swedish krona, the conversion of Elfa’s net sales into U.S. dollars resulted in a reduction of approximately $5.2 million for the quarter.

·                  The Company exceeded its stated outlook for the first quarter of ($0.12) to ($0.14) per share with a net loss of ($0.11) per share or $5.2 million in the first quarter of fiscal 2015 compared to a net loss of $3.6 million or ($0.07) per share for the first quarter of fiscal 2014. Net loss of approximately ($0.03) per share for the first quarter of 2015 is attributable to spend for key strategic initiatives and lost sales due to the West Coast port delays. The Company’s first quarter historically represents approximately 20% of its sales and also typically generates a net loss.

·    The Company opened its first of 10 planned stores for fiscal 2015 — in Tucson, AZ — to end the quarter with 71 stores and is on track to achieve its targeted 12% square footage growth for fiscal 2015.

“Our first quarter financial performance exceeded our expectations, as we delivered better than forecasted comparable store sales and improved gross margin,” said Kip Tindell, Chairman and Chief Executive Officer. “The implementation of our three major strategic initiatives — TCS Closets, Contained Home and POP! — remains on track, as planned, and we’re encouraged by the start of the ‘snowballing effect’ on their results. As we expected, we’ve seen that, in general, our stores with the strongest comparable store sales increases are the ones that have had TCS Closets and Contained Home the longest. In fact, if we isolate our seven Dallas-area stores, TCS Closets alone added three percentage points of incremental comparable store sales to those stores in the first quarter of fiscal 2015. We remain confident in, and are maintaining, our previously stated sales and EPS outlook for the fiscal year.”

·                  TCS ClosetsTM: The Company is pleased with the rollout of its new custom closet collection, with the average ticket continuing to exceed $10,000 since launch — greatly exceeding the Company’s day-to-day average ticket of approximately $60. With each store’s TCS Closets rollout, the Company is experiencing more rapid acceptance and action by customers and employees alike. The Company believes this shorter timeframe between launch and a store’s first sales is a result of the refinements and enhancements in training support, in-store displays, the selling process and overall customer experience. In addition, more than 90% of TCS Closets customers have made a subsequent purchase since buying a TCS Closet. The Company is encouraged by the synergistic relationship between TCS Closets and The Container Store’s best-selling product elfa® shelving and drawer system, both of which are located in the Company’s custom closet section of its stores. As the Company expected, there is a positive sales trend in both elfa® sales and elfa® average ticket in the stores that have had TCS Closets the longest.

TCS Closets was available in the planned 36 stores at the end of the first quarter and is on track to roll out to all current and new stores by the end of fiscal 2015:

The Company has launched a national marketing campaign to support TCS Closets, which includes advertising in home design magazines, direct mail, online presence, social media, special events and public relations.

·                  Contained HomeSM:  The Company’s in-home organization service was available in the planned 47 stores at the end of the first quarter and is also on track to roll out to all current and new stores by the end of fiscal 2015.  Average ticket is approximately $2,500 program-to-date.

The Company is rapidly contracting with additional Contained Home organizers and is now up to approximately 130 organizers to date. Satisfaction with Contained Home is high, with over 90% of customers giving the service a 4 or 5 out of 5 stars on the Company’s follow up survey. Contained Home will also be supported by a national marketing campaign, which includes advertising in home design magazines, direct mail, online presence, social media and public relations.

·                  POP! Perfectly Organized Perks®: The Container Store’s new customer engagement program has reached over 2 million members (POP! Stars) since launching in July 2014 and is adding about 25,000 members each week. As the Company enters the next phase of the program, it will further capitalize on its consumer data in order to create deeper, one-on-one, customized connections, offers and conversations with its customers.

The Company opened a store in Tucson, AZ (Tucson Mall) on May 30th and completed its first store opening for the second quarter on June 27th in Overland Park, KS (Hawthorne Plaza).

First Quarter 2015 Results

For the first quarter ended May 30, 2015, on a consolidated basis:

·                  Net sales were $169.8 million, down 2.1% as compared to the first quarter of fiscal 2014; however, net sales were up 0.9% after converting Elfa’s third-party net sales results from Swedish krona to U.S. dollars using the prior year’s conversion rate for both periods. The strengthening of the U.S. dollar against the Swedish krona led to a negative conversion impact of $5.2 million in the first quarter of fiscal 2015. Net sales in The Container Store retail business were $152.7 million, up 2.0% as compared to the first quarter of fiscal 2014. The increase in net sales was driven by new store sales, which more than offset the comparable store sales operating measure decline of 0.9%. In local currency, Elfa third-party net sales declined 5.8%, primarily due to lower sales in Russia and Norway.

·                  Gross margin was 58.5%, an increase of 40 basis points compared to the first quarter of fiscal 2014. The Container Store retail business gross margin remained stable at 58.2% as the impact of the stronger U.S. dollar on gross margin was offset by a shift in timing of elfa® product offers and the introduction of everyday free shipping on orders over $75, combined with a shift in product and services mix. Elfa gross margin declined 160 basis points primarily due to higher freight costs. On a consolidated basis, gross margin increased as the decline in Elfa gross margin was more than offset by the stability in The Container Store retail business gross margin, due to a larger percentage of net sales coming from The Container Store retail business.

·                  Selling, general and administrative expenses (“SG&A”) increased by 3.3% to $93.9 million from $90.9 million in the first quarter of fiscal 2014. SG&A as a percentage of net sales increased 290 basis points primarily due to the impact of a larger percentage of total net sales coming from The Container Store retail business, combined with increased healthcare costs, the expected increased costs related to strategic initiatives, and deleveraging of occupancy costs.

·                  Net interest expense decreased to $4.2 million from $4.3 million in the first quarter of fiscal 2014.

·                  The effective tax rate for the first quarter of fiscal 2015 was 36.7%, as compared to 35.0% in the first quarter of fiscal 2014. The increase in the effective tax rate is primarily due to a greater portion of our projected annual earnings expected to come from the U.S., which has a higher tax rate than our foreign subsidiaries.

·                  U.S. generally accepted accounting principles (“GAAP”) net loss was $5.2 million, or ($0.11) per diluted share, in the first quarter of fiscal 2015 compared to net loss of $3.6 million, or ($0.07) per diluted share in the first quarter of fiscal 2014. The non-GAAP measures of adjusted net loss and adjusted net loss per diluted share were the same as the respective GAAP measures in the first quarter of fiscal 2015 and the first quarter of fiscal 2014 as there were no reconciling items present in these periods (see GAAP/Non-GAAP reconciliation table).

·                  Adjusted EBITDA was $4.8 million in the first quarter of fiscal 2015 compared to $10.2 million in the first quarter of fiscal 2014 (see GAAP/Non-GAAP reconciliation table).

Balance sheet highlights:

*Cash plus availability on revolving credit facilities

Outlook

For fiscal 2015, consolidated net sales are expected to be $800 to $815 million, based on the Company’s expected store openings and a comparable store sales change of -2% to 0%. Net income is expected to be $0.30 to $0.38 per diluted common share based on estimated diluted common shares outstanding of 49 million. This assumes a tax rate of approximately 39% for the full year. Adjusted EBITDA is expected to be between $85 and $91 million.

This outlook incorporates approximately $4.5 million of expenses, or $0.06 per diluted common share, associated with the implementation of the above outlined key strategic initiatives.

Note Regarding Non-GAAP Information

This press release includes financial measures that are not calculated in accordance with GAAP, including adjusted net loss, adjusted net loss per diluted common share, adjusted EBITDA and net sales after the conversion of Elfa’s net sales from Swedish krona to U.S. dollars using the prior year’s 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.
