Management Discussion
  • The Company aligns its organizational structure into the following two reporting segments for the purpose of making operational decisions and assessing financial performance: (i) Compound Semiconductors and (ii) Photonic Solutions. The Company is reporting financial information (revenue and operating income) for these reporting segments in this Annual Report on Form 10-K.
  • Revenues. Revenues for the year ended June 30, 2020 increased 75% to $2,380.1 million, compared to $1,362.4 million for the prior fiscal year. The increase in revenues is primarily attributed to the acquisition of Finisar, which contributed $938.4 million of revenues for the fiscal year ended June 30, 2020. In addition to the acquisition of Finisar, the increase in revenues within Photonic Solutions was driven by increased demand from customers in the optical communication market, ROADM and other optical communication products addressing the growing deployment of 5G optical networks. Compound Semiconductors recorded a 13% revenue increase during the current fiscal year, which in addition to revenues from Finisar, was driven by strengthening demand for SiC substrate products addressing RF electronics and high-power switching systems. This segment also realized increased revenues from its aerospace and defense products addressing strengthening demand from customers in the intelligence, surveillance and reconnaissance markets.
  • Gross margin. Gross margin for the year ended June 30, 2020 was $819.6 million, or 34.4%, of total revenues, compared to $521.3 million, or 38.3% of total revenues, for the same period last fiscal year. Gross margin as a percentage of revenues decreased 380 basis points compared to the prior fiscal year despite the 75% increase in revenues during this same period. Gross margin was negatively impacted by additional cost of goods sold of $87.7 million related to the fair value adjustment of the acquired Finisar inventory, and as the result of product mix relating to Finisar's Transceiver product line which has a lower gross margin profile than the Company's historical margins.
