Breakdown of Retail and Manufacturing/ Wholesale Results

•
Retail Division

        In the third quarter, year-over-year retail sales declined by 4.7 percent to EUR 530.4 million. Assuming constant exchange rates, retail sales for the quarter would have increased by 7.0 percent. Excluding OPSM, same store sales in U.S. Dollars for the quarter remained unchanged compared to the same period last year, posting an improvement when compared to the decline of 3.4 percent in the first half of 2003.

        Retail operating income for the quarter was EUR 88.4 million. In U.S. Dollars, it increased by 4.7 percent. Retail operating margin was 16.6 percent.

        In the nine-month period, retail sales declined year-over-year by 15.3 percent to EUR 1,470.5 million. Assuming constant exchange rates, retail sales for the nine months would have declined by 0.6 percent. Excluding OPSM, same store sales in U.S. Dollars for the nine-month period declined year-over-year by 2.3 percent.

        Retail operating income for the nine-month period was EUR 210.3 million, resulting in an operating margin of 14.3 percent.

        Leonardo Del Vecchio, chairman of Luxottica Group commented on the results of the Retail division: "In the third quarter, the retail division improved performance when compared to the first half of the year. This improvement is primarily due to better economic conditions in North America.

        In addition, even with flat same store sales, when compared to the third quarter of 2002, we experienced a considerable recovery in retail profitability. This was the result of improved efficiencies in the management of store personnel and other effective measures put in place by management to better control costs.

        This improving trend is further confirmed from the performance of the division during October."

•
Manufacturing/Wholesale Division

        The Group's manufacturing/wholesale sales for the nine-month period declined year-over-year by 13.0 percent to EUR 773.9 million. Assuming constant exchange rates manufacturing/wholesale sales for the nine months would have declined 5.5 percent.

        Manufacturing/wholesale operating income for the nine-month period was EUR 153.4 million, reflecting an operating margin of 19.8 percent.

        Mr Del Vecchio, continued: "I'm pleased to report to you that we are experiencing a reversal in the negative sales trend. Since the beginning of September, sales of the new collections were approximately equal to the Armani revenues. Therefore, the third quarter was the last quarter in which revenues were negatively impacted by the expiration of the Armani license.

        This improving trend is further confirmed by our orders, which in October exceeded last year's level, as we started introducing the Prada and Miu Miu eyewear collections. This recovery gives us renewed confidence in the performance of wholesale sales going forward.

        During the quarter, wholesale profitability was impacted by the end of the Armani license, as well as the devaluation of the U.S. Dollar. In fact, the decrease in operating margin is primarily due to the high level of returns of Armani eyewear which were concentrated in this quarter.

3


        In summary, I'm confident that beginning in 2004, and excluding the negative exchange rate effect, the wholesale division will return to normal levels of profitability."


Statement from the Chairman

        Mr. Del Vecchio concluded: "Worldwide economic conditions remain difficult and the U.S. Dollar is weak and volatile, but, as expected, the impact of these factors which negatively affected first half results is progressively lessening.

        The adverse exchange rate effect resulting from the devaluation of the U.S. Dollar against the Euro decreased from 18.7 percent in the first six months of 2003 to 12.5 percent in the third quarter.

        In addition, there are encouraging signs of an economic recovery in the U.S., which leads us to expect a gradual and progressive improvement in same store sales going forward.

        Finally, the introduction and marketing of the Versace, Prada, Miu Miu and Ray-Ban ophthalmic collections are making up for the expiration of the Armani license from the beginning of September.

        Third quarter performance make us optimistic in the future of our Group. We can therefore, confirm our previous guidance for 2003 and 2004, a year in which we expect to return to approximately 15 percent growth in sales and earnings as a result of the significantly strengthened brand portfolio, both house brands and designer lines, and the OPSM acquisition.

        During the quarter, we completed the OPSM acquisition. This acquisition has given the Group the leadership position in the prescription business, and substantially strengthened our leadership position in the sunglass business in the Australian and New Zealand markets, while at the same time presented us with new and promising growth opportunities in this area."

Non-GAAP Financial Measures

        Luxottica Group uses certain measures of financial performance that exclude the impact of fluctuations in currency exchange rates in the translation of operating results into Euro. The Company believes that these adjusted financial measures provide useful information to both management and

4


investors by allowing a comparison of operating performance on a consistent basis. In addition, since the Luxottica Group has historically reported such adjusted financial measures to the investment community, the Company believes that their inclusion provides consistency in its financial reporting. Further, these adjusted financial measures are one of the primary indicators management uses for planning and forecasting in future periods. Operating measures that assume constant exchange rates between the nine-month period and the third quarter of 2003 and the nine-month period and the third quarter of 2002 are calculated using for each currency the average exchange rate for the nine-month period and the three-month period ended September 30, 2002. Operating measures that exclude the impact of fluctuations in currency exchange rates are not measures of performance under accounting principles generally accepted in the United States (U.S. GAAP). These non-GAAP measures are not meant to be considered in isolation or as a substitute for results prepared in accordance with U.S. GAAP. In addition, Luxottica Group's method of calculating operating performance excluding the impact of changes in exchange rates may differ from methods used by other companies. See Table below for a reconciliation of the operating measures excluding the impact of fluctuations in currency exchange rates to their most directly comparable U.S. GAAP financial measures. The adjusted financial measures should be used as a supplement to U.S. GAAP results to assist the reader in better understanding the operational performance of the Company.

Notes :

(1)
Certain amounts presented in the prior year financial statements have been reclassified to conform with the current year presentation. Among them was a reclassification of certain revenue items of the retail division which were recorded in prior year as a reduction in the related costs and are now reflected as gross revenues and gross costs. The effect of this reclassification is an increase in sales for the nine-month period ended September 30, 2002 of U.S. Dollars 34.1 million, and an offsetting increase in costs for the same amounts

(2)
These consolidated adjusted amounts are a non-GAAP measurement. The company has included this measurement to give comparative information for the two periods discussed. They reflect the consolidation of OPSM results for the two-month period ended September 30, 2002. This information does not purport to be indicative of the actual result that would have been achieved had the OPSM acquisition been completed as of August 1, 2002

Luxottica Group Announces Public Offer to
Acquire Additional 20 percent of RayBan Sun Optics
—Subject to the Decision by the Supreme Court of India—

        Milan, Italy, October 30, 2003—Luxottica Group S.p.A.

RayBan Sun Optics is a company listed on the Indian market.

        Luxottica Group had appealed against the decision that required Luxottica Group to make a public offer to the Supreme Court of India. Following the appeal, the Supreme Court mentioned that the public announcement and any further steps related to this offer will be subject to its decision.

        Leonardo Del Vecchio, Chairman of Luxottica Group, stated: "As announced earlier, the maximum expected investment related to this offer, would be approximately EUR 16 million, including stipulated interest increment, which would have no material financial impact on the Group. As a result of the offer, in case of full acceptance, the indirect shareholding in RayBan Sun Optics India Ltd. would increase from approximately 44 percent to 64 percent."
