COMPARISON OF THE RESULTS OF OPERATIONS FOR THE SIX MONTHS ENDED JANUARY 31, 2005 AND JANUARY 31, 2004 Net Sales. Consolidated net sales were $134.2 million and $113.1 million for the six months ended January 31, 2005 and 2004, respectively, representing an increase of $21.1 million or 18.7%. The increase in net sales was primarily attributable to increased demand for our products in all three business segments. Net sales in our telecommunications transmission segment were $77.1 million and $68.8 million for the six months ended January 31, 2005 and 2004, respectively, an increase of $8.3 million or 12.1%. The growth in this segment resulted, in part, from a significant increase in demand for our satellite earth station products. In addition, sales relating to the Memotec business, which we acquired in May 2004, were $3.1 million for the six months ended January 31, 2005. We expect the $77.0 million over-the-horizon microwave system contract that we received in September 2004 to result in increased sales in this product line for the remainder of fiscal 2005, offset in part, by anticipated lower sales from two other large contracts that are nearing completion. The adjustment to the estimated gross profits at completion (see“Gross Profit” above) on these contracts, including the portion recorded in the first quarter of fiscal 2005, resulted in $3.6 million of sales for the six months ended January 31, 2005. Our telecommunications transmission segment represented 57.5% and 60.8% of consolidated net sales for the six months ended January 31, 2005 and 2004, respectively. Net sales in our mobile data communications segment were $39.5 million and $34.7 million for the six months ended January 31, 2005 and 2004, respectively, an increase of $4.8 million or 13.8%. The increase in sales was primarily due to the adjustment discussed above in the three month comparison, which resulted in $3.8 million of sales for the six months ended January 31, 2005. Our mobile data communications segment represented 29.4% and 30.7% of consolidated net sales for the six months ended January 31, 2005 and 2004, respectively. Net sales in our RF microwave amplifier segment were $17.6 million for the six months ended January 31, 2005, as compared to net sales of $9.6 million for the six months ended January 31, 2004, an increase of $8.0 million or 83.3%. The improvement in this segment’s net sales resulted primarily from increased demand for our defense related products. Our RF microwave amplifier segment represented 13.1% and 8.5% of consolidated net sales for the six months ended January 31, 2005 and 2004, respectively. International sales (which include sales to domestic companies for inclusion in products which are sold to international customers) represented 41.5% and 43.5% of consolidated net sales for the six months ended January 31, 2005 and 2004, respectively. Domestic commercial sales represented 12.1% and 14.8% of consolidated net sales for the six months ended January 31, 2005 and 2004, respectively. Sales to the U.S. government (including sales to prime contractors to the U.S. government) represented 46.4% and 41.7% of consolidated net sales for the six months ended January 31, 2005 and 2004, respectively. Except for sales to the U.S. government, no customer represented 10% or more of consolidated net sales in the six months ended January 31, 2005. During the six months ended January 31, 2004, sales to one customer, a prime contractor, represented 23.3% of consolidated net sales. Direct and indirect sales to a North African country, including certain sales to the prime contractor mentioned above, during the six months ended January 31, 2005 and 2004 represented 10.8% and 16.0%, respectively, of consolidated net sales. Gross Profit. Gross profit was $59.4 million and $41.6 million for the six months ended January 31, 2005 and 2004, respectively, representing an increase of $17.8 million. The increase in gross profit was attributable to the increase in net sales and the gross margin percentage, which increased from 36.8% for the six months ended January 31, 2004 to 44.3% for the six months ended January 31, 2005. The increase in the gross margin, as a percentage of consolidated net sales, was primarily due to (i) increased sales of our satellite earth station products, which typically realize higher margins than sales of our other products, (ii) increased operating efficiencies, and (iii) the impact on gross profit of the cumulative adjustments discussed above aggregating $5.8 million (of which $2.2 million relates to the mobile data communications segment and $3.6 million relates to the telecommunications transmission segment). Excluding the sales and gross profit relating to prior periods from the adjustments, our gross profit as a percentage of sales for the six months ended January 31, 2005 would be 42.3%. Included in cost of sales for the six months ended January 31, 2005 and 2004 are provisions for excess and obsolete inventory of $0.8 million in both periods. As discussed under“Critical Accounting Policies - Provisions for Excess and Obsolete Inventory,” we regularly review our inventory and record a provision for excess and obsolete inventory based on historical usage assumptions and other factors. 17
