MONTREAL, September 9, 2015 (GLOBE NEWSWIRE) — DAVIDsTEA Inc. (Nasdaq:DTEA) today announced financial results for the thirteen weeks ended August 1, 2015.

For the thirteen weeks ended August 1, 2015:

·                  Sales increased by 32% to C$32.8 million from C$24.9 million in the second quarter of fiscal 2014. Comparable sales increased by 6.9%.

·                  Gross profit increased by 27% to C$16.1 million while gross profit as a percent of sales decreased to 49.0% from 51.0% in the second quarter of fiscal 2014. The decrease in gross profit as a percent of sales was driven primarily by the adverse impact from the stronger U.S. dollar on U.S. dollar denominated purchases. On a constant currency basis, gross profit as a percent of sales was 51.5%.

·                  Selling, general and administration expenses (“SG&A”) increased to C$18.2 million from C$13.8 million in the second quarter of fiscal 2014. Excluding IPO-related and other one-time costs, SG&A increased to C$17.9 million from C$13.8 million in the second quarter of fiscal 2014. As a percent of sales, SG&A excluding these one-time costs decreased to 54.6% from 55.4%.

·                  Results from operating activities were C$(2.2) million as compared to C$(1.1) million in the second quarter of fiscal 2014. Excluding the impact of the IPO and other one-time costs, results from operating activities decreased to C$(1.9) million from C$(1.1) million in the second quarter of fiscal 2014.

·                  The Company opened 4 net new stores in the second quarter and ended the quarter with a total of 165 stores in Canada and the U.S. This represents an increase of 27% from the end of the second quarter of fiscal 2014.

·                  Adjusted EBITDA was C$0.2 million compared to C$0.5 million in the second quarter of fiscal 2014. Adjusted EBITDA excludes IPO-related and other non-cash or one-time costs (see Reconciliation of Adjusted EBITDA table).

·                  Net loss was C$(52.1) million compared to C$(2.7) million in the second quarter of fiscal 2014. The decrease in net income in the second quarter is due to a $50.2 million non-cash loss associated with the embedded derivative on Series A, A-1 and A-2 preferred shares. In conjunction with the IPO transaction, all preferred stock was converted into common stock. As a result, this charge will not reoccur given the conversion of preferred shares. Adjusted net loss, which excludes IPO-related and other one-time costs in the second quarter of fiscal 2015 (see Reconciliation of IFRS basis to Adjusted net loss table), was C$(1.6) million compared to C$(1.4) million for the second quarter of fiscal 2014.

·                  Fully diluted income per common share was C$(2.73) compared to C$(0.22) in the second quarter of fiscal 2014. Adjusted fully diluted income per common share, which is adjusted net income on an adjusted fully diluted weighted average shares outstanding basis (see Reconciliation of fully diluted weighted average common shares outstanding table), was C$(0.07) per share compared to C$(0.06)per share in the second quarter of fiscal 2014.

Sylvain Toutant, President and Chief Executive Officer, stated: “We had a great second quarter, delivering a 32% increase in sales and our 24th consecutive comparable sales increase with growth of 6.9%. This strong sales performance across both new and existing stores once again demonstrates the strength of our concept with its broad, unique and innovative multi-channel offering, in an industry that is benefitting from consumer trends with wide demographic appeal.”

Mr. Toutant continued, “With a current base of 168 stores and North American potential for 550 stores, there is a long runway of growth ahead for DAVIDsTEA. We remain excited about our business and the many opportunities that we have to expand the brand and grow our top and bottom line, and are well positioned to deliver on both our near and longer term goals.”

For the twenty six weeks ended August 1, 2015:

·                  Sales increased by 30% to C$68.6 million from C$52.7 million in the comparable period in fiscal 2014. Comparable sales

increased by 6.6%.

·                  Gross profit increased by 24% to C$35.1 million while gross profit as a percent of sales decreased to 51.2% from 53.9% in the comparable period in fiscal 2014. The decrease in gross profit as a percent of sales was driven primarily by the adverse impact from the stronger U.S. dollar on U.S. dollar denominated purchases, as well as due to investments in supply chain. On a constant currency basis, gross profit as a percent of sales was 53.6%.

·                  Selling, general and administration expenses (“SG&A”) increased to C$39.3 million from C$27.1 million in the comparable period in fiscal 2014. Excluding IPO-related and other one-time costs, SG&A increased to C$34.9 million from C$27.1 million in the second quarter of fiscal 2014. As a percent of sales, SG&A, excluding these one-time costs, decreased to 50.9% from 51.4%.

·                  Results from operating activities were C$(4.1) million as compared to C$1.3 million in the comparable period in fiscal 2014. Excluding the impact of the IPO and other one-time costs, results from operating activities decreased to C$0.2 million from C$1.3 million in the comparable period in fiscal 2014.

·                  The Company opened 11 net new stores in the twenty six weeks ended August 1, 2015 and ended the period with a total of 165 stores in Canada and the U.S. This represents an increase of 27% from the comparable period in fiscal 2014.

·                  Adjusted EBITDA was C$4.2 million compared to C$4.4 million in the comparable period in 2014. Adjusted EBITDA excludes IPO-related and other non-cash or one-time costs (see Reconciliation of Adjusted EBITDA table).

·                  Net loss was C$(145.3) million compared to C$(1.2) million in the comparable period in fiscal 2014. The decrease in net income in the first half of fiscal 2015 is due to a $140.9 million non-cash loss associated with the embedded derivative on Series A, A-1 and A-2 preferred shares. In conjunction with the IPO transaction, all preferred stock was converted into common stock. As a result, this charge will not reoccur given the conversion of preferred shares. Adjusted net loss, which excludes IPO-related and other one-time costs for the twenty six weeks ended August 1, 2015 (see Reconciliation of IFRS basis to Adjusted net loss table), was C$(0.5) million compared to C$(0.0) million for the comparable period in fiscal 2014.

·                  Fully diluted income per common share was C$(9.35) compared to C$(0.10) in the comparable period in fiscal 2014. Adjusted fully diluted income per common share, which is adjusted net income on an adjusted fully diluted weighted average shares outstanding basis (see Reconciliation of fully diluted weighted average common shares outstanding table), was C$(0.02) per share compared to C$(0.00) per share in the comparable period in fiscal 2014.

Balance sheet highlights as of August 1, 2015:

·                  Cash: C$62.7 million.

·                  Total liquidity (cash plus availability on a C$20.0 million revolver facility): C$82.7 million.

·                  Our initial public offering closed on June 10, 2015. Net proceeds to the Company, after IPO-related costs, were C$68.9 million, which were used to repay debt and for working capital and general corporate purposes.

Third Quarter and Fiscal 2015 Outlook:

For the third quarter of fiscal 2015, sales are expected to be in the range of C$34 million to C$35 million based on opening 17 new stores and assuming a comparable sales increase slightly above the mid-single digit range. Adjusted EBITDA is expected to be in the range of C$1.0 million to C$1.3 million. Adjusted net loss is expected to be in the range of C$(0.8) million to C$(1.0) million, with an adjusted fully diluted loss per common share range of C$(0.03) to C$(0.04) on approximately 23.9 million estimated fully diluted weighted average shares outstanding.

For fiscal 2015, sales are expected to be in the range of C$173 million to C$176 million based on opening 40 net new stores for the full year and assuming a comparable sales increase slightly above the mid-single digit range. Adjusted EBITDA is expected to be in the range of C$23 million to C$24 million. Adjusted net income, which excludes IPO-related and other one-time costs, is expected to be in the range of C$9 million to C$10 million, or C$0.35 to C$0.39 per share on approximately 26.3 million adjusted fully diluted common shares outstanding.

Conference Call Information:

A conference call to discuss the second quarter fiscal 2015 financial results is scheduled for today, September 9, 2015, at 4:30 p.m. Eastern Daylight Time.

Non-IFRS Information:

This press release includes non-IFRS measures including Adjusted EBITDA, Adjusted net income(loss), and Adjusted fully diluted income(loss) per share. Adjusted EBITDA, Adjusted net income(loss) and Adjusted fully diluted income(loss) per share are not presentations made in accordance with IFRS, and the use of the terms Adjusted EBITDA, Adjusted net income(loss) and Adjusted fully diluted income(loss) per share may differ from similar measures reported by other companies. We believe that Adjusted EBITDA, Adjusted net income(loss) and Adjusted fully diluted income(loss) per share provide investors with useful information with respect to our historical operations. We present Adjusted EBITDA, Adjusted net income(loss) and Adjusted fully diluted income(loss) per share as supplemental performance measures because we believe they facilitate a comparative assessment of our operating performance relative to our performance based on our results under IFRS, while isolating the effects of some items that vary from period-to-period. Specifically, Adjusted EBITDA, Adjusted net income(loss) and Adjusted fully diluted income(loss) per share allow for an assessment of our operating performance and our ability to service or incur indebtedness without the effect of non-cash charges of the period or other one-time charges, such as depreciation, amortization, impairment costs, costs related to onerous contracts or contracts where we expect the costs of the obligations to exceed the economic benefit and non-recurring expenses relating to our initial public offering. These measures also function as benchmarks to evaluate our operating performance. Adjusted EBITDA, Adjusted net income (loss), and Adjusted fully diluted income(loss) per share are not measurements of our financial performance under IFRS and should not be considered in isolation or as alternatives to net income, net cash provided by operating, investing or financing activities or any other financial statement data presented as indicators of financial performance or liquidity, each as presented in accordance with IFRS. We understand that although Adjusted EBITDA, Adjusted net income(loss), and Adjusted fully diluted income(loss) per share are frequently used by securities analysts, lenders and others in their evaluation of companies, they have limitations as analytical tools, and you should not consider them in isolation, or as a substitute for analysis of our results as reported under IFRS. Some of these limitations are:

·                  Adjusted EBITDA, Adjusted net income(loss), and Adjusted fully diluted income(loss) per share do not reflect changes in, or cash requirements for, our working capital needs;

·                  Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and Adjusted EBITDA does not reflect any cash requirements for such replacements.

Because of these limitations, Adjusted EBITDA, Adjusted net income(loss), and Adjusted fully diluted income(loss) per share should not be considered as discretionary cash available to us to reinvest in the growth of our business or as a measure of cash that will be available to us to meet our obligations.
