INTER PARFUMS, INC. REPORTS 2018 THIRD QUARTER RESULTS

INCREASES DIVIDEND 31%

New York, New York, November 5, 2018: Inter Parfums, Inc. (NASDAQ GS: IPAR) today reported results for the third quarter ended September 30, 2018.

Third Quarter 2018 Compared to Third Quarter 2017:

Discussing European based operations, Jean Madar, Chairman & CEO of Inter Parfums stated, “Jimmy Choo and Coach, two of our largest brands, achieved 19.7% and 40.9% third quarter sales growth, respectively, all the more impressive in the absence of major new product launches. In fact, the nearly 12% year-to-date increase in net sales by European based operations was primarily due to brand extensions for the best sellers among our largest brands, energizing product selections within our other brands and expanding distribution, all the while supporting these efforts with well-planned and executed advertising and promotional programs with a far greater emphasis on digital media.”

On the subject of U.S. based operations, Mr. Madar continued, “The inclusion of legacy GUESS fragrances, which began in the second quarter of 2018, factored into the increase in net sales. Also factoring into the third quarter sales growth was the successful launch of brand extensions for the Abercrombie & Fitch First Instinct fragrance family and Hollister’s Festival Vibes duo. Additionally, with the popularity of Anna Sui fragrances throughout Asia, we continue to enjoy dramatic increases in brand sales in that region.”

Mr. Madar noted, “Nearly all of the regions in which we do business have shown year-to-date sales growth. Our three largest markets, North America, Western Europe and Asia, achieved sales growth of 18%, 9% and 22%, respectively, compared to the first nine months of 2017. The Middle East and Eastern Europe, have grown sales by 11% and 12%, respectively, while Central and South America sales were essentially flat compared to the same period last year.”

Discussing new product launches for 2019 he continued, “On both sides of the Atlantic, we have ambitious plans for the coming year. With regard to European operations, our largest brands, Montblanc and Jimmy Choo, both have new men’s scents debuting and there will be new women’s fragrances for Coach and Lanvin. For U.S. operations, 2019 launches are for the most part brand extensions including one for Anna Sui’s Fantasia, an addition to the GUESS 1981 fragrance family, a sister scent for Oscar de la Renta’s Bella Blanca, and a flanker for the Dunhill Century fragrance line. among others.”

On the subject of newer brands under the U.S. based operations, Mr. Madar noted, “We are developing a four-scent super luxury collection for Graff, along with an amenities line, geared for five-star hotels. As we recently announced, we have initiated a direct-to-the consumer e-commerce enterprise in partnership with IMG Models, and our first multi-scent fragrance collaboration with super model Lily Aldridge, is planned for next year.”

Discussing profitability factors, Mr. Greenberg stated, “For European operations, gross profit margin was 65% in both the current and prior year’s third quarter and once again, the dollar/euro ratio had little impact on our gross margin. For U.S. operations, gross profit margin rose to 50% as compared to 47% in the third quarter of 2017, with the improvement attributable to increased sales of higher margin prestige products under licenses. For European operations, selling, general and administrative expenses increased 2% and represented 44% of net sales in both the current third quarter and the corresponding period of the prior year. At the same time, selling, general and administrative expenses of our U.S. operations increased 25% and represented 35% of net sales compared to 32% in the corresponding period of the prior year with the increase directly associated with the increase in net sales of licensed products.”

He continued, “With regard to non-operating items, the loss on foreign currency increased to $1.1 million in the current third quarter, as compared to $0.3 million in last year’s third quarter, which was more than offset by a decrease in our effective tax rate to 29% in the current third quarter from 33% in last year’s third quarter.”

Mr. Greenberg also pointed out, “We closed the quarter with working capital of $383 million, including approximately $211 million in cash, cash equivalents and short-term investments, a working capital ratio of nearly 3.4 to 1 and $52.0 million of long-term debt, including current maturities, incurred in connection with the 2015 Rochas brand acquisition.”

Guidance

Mr. Greenberg concluded, “We continue to anticipate approximately $665 million in net sales for full year resulting in net income per diluted share attributable to Inter Parfums, Inc. of $1.61. Guidance assumes the dollar remains at current levels. As we reported last month, we have scheduled November 12, 2018, after the close of the market, for the release of our initial 2019 guidance.”

Dividend Increase

The Board of Directors of Inter Parfums, Inc. authorized a 31% increase in the annual dividend to $1.10 per share. The next quarterly cash dividend of $0.275 per share is payable on January 15, 2019 to shareholders of record on December 31, 2018.
