Iconix Brand Group Reports Preliminary Second Quarter 2017 Financial Results

NEW YORK, Aug. 9, 2017 /PRNewswire/ —

Iconix Brand Group, Inc. (NASDAQ: ICON) (“Iconix” or the “Company”) today reported preliminary financial results for its second quarter ended June 30, 2017.

John Haugh, CEO of Iconix commented, “Today we are reporting second quarter revenue results that show an improvement from the first quarter. We entered the year with two primary goals, first to strengthen the balance sheet and enhance financial flexibility, and second to execute on our organic growth strategy. With the refinancing announced last week, we can report that our near-term balance sheet objectives are substantially complete. We know we need to deliver on both of our objectives. To that end, organic growth is taking longer than originally anticipated, but we are fully focused on our organic growth objectives and will have more to share with you in the coming weeks and months.”

In the course of finalizing the results for the second quarter of 2017, the Company determined that its Southeast Asia joint venture should be deconsolidated. This deconsolidation was triggered by its joint venture partner’s payment of the final purchase price installment in respect of its interest in the Southeast Asia joint venture, which the Company received in late June. Flowing such deconsolidation through the Company’s financial statements is a time intensive process and as a result, the Company is reporting today its preliminary results, excluding the effect of this deconsolidation, which will change as described herein. The Company will file its 10-Q by August 14, 2017.

Preliminary Second Quarter 2017 Financial Results

Preliminary results for the second quarter ended June 30, 2017 do not reflect the non-cash gain that the Company expects to record in the second quarter of 2017 related to the deconsolidation of its Southeast Asia joint venture. As such, among other items footnoted herein, the Company’s GAAP operating income, GAAP net income and GAAP earnings per share for the second quarter of 2017 will be adjusted following the date hereof to reflect such gain. Such gain will be excluded from the Company’s non-GAAP results.

Results for the second quarter ended June 30, 2017 reflect the entertainment segment as a discontinued operation. Unless otherwise noted, results presented in this press release are based on continuing operations.

Licensing Revenue:

For the second quarter of 2017, licensing revenue was $61.6 million, a 10% decline as compared to $68.2 million in the prior year quarter. Revenue in the prior year’s second quarter included approximately $1.6 million of licensing revenue from the Sharper Image brand which was sold in the fourth quarter of 2016. As a result, there was no comparable revenue in the second quarter of 2017. Excluding revenue from the Sharper Image brand, revenue declined approximately 7% in the second quarter of 2017.

Segment Data (Non-GAAP for exclusion of divested brands):

SG&A Expenses:

Total SG&A expenses in the second quarter of 2017 were $26.8 million, a 9% decrease as compared to approximately $29.5 million in the second quarter of 2016. The decline was primarily related to lower compensation expense and lower bad debt expense.

Special charges, which are included in SG&A and are related to professional fees associated with correspondence with the Staff of the SEC, the SEC investigation, the class action and derivative litigations, and costs related to the transition of Iconix management were approximately $2.5 million in the second quarter of 2017, as compared to $1.9 million in the prior year quarter. The Company excludes special charges from its non-GAAP net income and non-GAAP EPS.

Operating Income (1):

Operating Income in the second quarter of 2017 was $12.1 million, as compared to $38.0 million in the second quarter of 2016. Operating income in the second quarter of 2017, included a $23.2 million charge primarily related to licensee terminations associated with the transition of a new license. Operating income in the second quarter of 2016 included $1.5 million of income related to the Sharper image brand and a $1.1 million loss from the sale of trademarks. Excluding these items, operating income was approximately $35.3 million in the second quarter of 2017, a 6% decline from approximately $37.6 million in the second quarter of 2016.

Interest Expense:

Interest expense in the second quarter of 2017 was $14.1 million, a 35% decline as compared to interest expense of $21.9 million in the second quarter of 2016. The Company’s reported interest expense includes non-cash interest related to its outstanding convertible notes of $4.3 million in the second quarter of 2017 and $6.8 million in the second quarter of 2016. Excluding the non-cash interest related to the company’s outstanding convertible notes, interest expense was $9.8 million in the second quarter of 2017, as compared to $15.1 million in the second quarter of 2016. The lower interest expense is related to the Company’s reduction of debt over the past year.

Other Income:

In the second quarter of 2017, the Company recognized a $13.9 million expense related to the early extinguishment of a portion of the Company’s term loan, and in the second quarter of 2016 the Company recognized a gain of $4.3 million primarily related to the repurchase of a portion of the Company’s 2018 convertible notes at a discount. The Company has excluded these items from its non-GAAP results.

GAAP Net Income and GAAP Diluted EPS (1):

GAAP net income from continuing operations for the second quarter of 2017 was a loss of $16.3 million as compared to income of $10.6 million in the second quarter of 2016. The decline was primarily related to a licensee termination charge and a loss on the early extinguishment of debt. GAAP diluted EPS from continuing operations for the second quarter of 2017 was a loss of $0.30 as compared to diluted earnings per share of approximately $0.21 in the second quarter of 2016.

Non-GAAP Net Income and Non-GAAP Diluted EPS:

Non-GAAP net income from continuing operations for the second quarter of 2017 was $15.2 million, an 18% increase as compared to $12.9 million in the second quarter of 2016.

Non-GAAP diluted EPS from continuing operations for the second quarter of 2017 was $0.26 as compared to $0.25 in the second quarter of 2016.

The cash benefit from the amortization of wholly-owned U.S. intangible assets for tax purposes was approximately $0.13 in the second quarter of 2017 as compared to $0.15 in the second quarter of 2016. Non-GAAP EPS adjusted for non-cash taxes related to the amortization of wholly-owned intangible assets amortizable for U.S. income tax purposes was approximately $0.39 in the second quarter of 2017 as compared to $0.40 in the second quarter of 2016.

Balance Sheet and Liquidity:

The Company ended the second quarter of 2017 with approximately $313 million of total cash and $980 million face value of debt. In the second quarter of 2017, the Company paid down approximately $224 million of debt and, has subsequent to June 30, 2017 paid down an additional $167 million in the third quarter of 2017.

Prior to entering into a new $300 million term loan last week, of which the proceeds will be used to repay the $295 million of convertible notes due in March 2018 (with the remainder being used for general corporate purposes), the Company’s total face value of debt was $814 million and the Company had approximately $137 million of cash on its balance sheet.

Free Cash Flow

The Company generated approximately $10.6 million of free cash flow from continuing operations in the second quarter of 2017, as compared to approximately $38.7 million in the second quarter of 2016. The decline is primarily related to the $23.2 million charge in the second quarter related to licensee terminations. Note that free cash flow in the second quarter 2017 excludes the effect of the deconsolidation of the Southeast Asia joint venture, which the Company expects to have an immaterial impact to free cash flow.

Note that in June 2017 the company received $345 million of cash from the sale of the entertainment segment.

The following is a reconciliation of the non-GAAP financial measures used by the Company to describe the Company’s financial results determined in accordance with United States generally accepted accounting principles (GAAP).

While management believes that these non-GAAP financial measures provide useful supplemental information to investors regarding the underlying performance of the Company’s business operations, investors are reminded to consider these non-GAAP financial measures in addition to, and not as a substitute for, financial performance measures prepared in accordance with GAAP. In addition, it should be noted that these non-GAAP financial measures may be different from non-GAAP financial measures used by other companies, and management may utilize other measures to illustrate performance in the future. Non-GAAP financial measures have limitations in that they do not reflect all of the amounts associated with the Company’s results of operations as determined in accordance with GAAP.

Note: All items in the following reconciliation tables are attributable to Iconix Brand Group, Inc. and exclude results related to non-controlling interests. Certain numbers may not add due to rounding.

Footnotes

(1) In the second quarter of 2017, the Company expects to recognize a non-cash gain related to the deconsolidation of its Southeast Asia joint venture. The amount of such gain remains subject to being finalized and is not reflected herein. As such, the Company’s GAAP operating income, income before taxes, net income and earnings per share for the three month and six month periods ended June 30, 2017 will be revised following the date hereof.

(2) Non-GAAP net income and non-GAAP diluted EPS (along with non-GAAP weighted average diluted shares) are non-GAAP financial measures which represent net income excluding any non-cash interest related to ASC Topic 470, non-cash, non-recurring gains and charges, foreign currency translation gains and losses, and charges related to professional fees incurred as a result of the correspondence with the Staff of the SEC, the SEC investigation, internal investigations, the previously disclosed class action and derivative litigations, and costs related to the transition of Iconix management, all net of tax, and any incremental dilutive shares related to our convertible notes that are covered by their respective hedges. The Company believes these are useful financial measures in evaluating its financial condition because they are more reflective of the Company’s business purpose, operations and cash expenses.

Based on the average closing stock price for the quarters ended June 30, 2017 and June 30, 2016, there were no potential dilutive shares related to our convertible notes for GAAP purposes.

(3) Free Cash Flow, a non-GAAP financial measure, represents net cash provided by operating activities, plus cash received from the sale of trademarks and formation of joint ventures, less distributions to non-controlling interests and capital expenditures. Free Cash Flow excludes notes receivable from sale of trademarks and the formation of joint ventures, cash used to acquire the membership interests of our joint venture partners, mandatory debt service requirements, and other non-discretionary expenditures. Free Cash Flow should not be considered in isolation, as a measure of residual cash flow available for discretionary purposes, or as an alternative to operating results presented in accordance with GAAP. The Company believes Free Cash Flow is useful because it provides information regarding actual cash received in a specific period from the Company’s comprehensive business strategy of maximizing the value of its brands through traditional licensing, international joint ventures and other arrangements. We have excluded the cash used to buy back our joint venture membership interests from the above definition because we believe that, like other acquisitions, such actions are capital transactions. It also provides supplemental information to assist investors in evaluating the Company’s financial condition and ability to pursue opportunities that enhance shareholder value.
