Zoom Telephonics's Comment on Supply Chain

Our products are currently designed for high-volume automated assembly to help assure reduced costs, rapid market entry, short lead times, and reliability. High-volume assembly typically occurs in China or Taiwan. Our contract manufacturers and original design manufacturers typically obtain some or all of the material required to assemble the products based upon a Zoom Telephonics Approved Vendor List and Parts List. Our manufacturers typically insert parts onto the printed circuit board, with most parts automatically inserted by machine, solder the circuit board, and test the completed assemblies. The contract manufacturer sometimes performs final packaging. For the US and many other markets, packaging is often performed at our facilities in North America, allowing us to tailor the packaging and its contents for our customers immediately before shipping. This facility also performs warehousing, shipping, quality control, finishing and some software updates from time to time. We also perform circuit design, circuit board layout, and strategic component sourcing at our Boston headquarters. Wherever the product is built, our quality systems are used to help assure that the product meets our specifications.

Our North American facility is currently located in Tijuana, Mexico. From time to time we experience certain challenges associated with the Tijuana facility, specifically relating to bringing products across the border between the US and Mexico. We believe that this facility assists us in cost-effectively providing rapid response to the needs of our US customers.

Historically we have used one primary manufacturer for a given design. We sometimes maintain back-up production tooling at a second manufacturer for our highest-volume products. Our manufacturers are normally adequate to meet reasonable and properly planned production needs; but a fire, natural calamity, strike, financial problem, or other significant event at an assembler's facility could adversely affect our shipments and revenues. In 2017, one supplier provided 97% of our purchased inventory. The loss of a key supplier, or a material adverse change in a key supplier’s business or in our relationship with a key supplier, could materially and adversely harm our business.

Our products include a large number of parts, most of which are available from multiple sources with varying lead times. However, most of our products include a sole-sourced chipset as the most critical component of the product. The vast majority of our cable and DSL modem chipsets come exclusively from Broadcom. Most of our cellular products include a Gemalto module. Our dial-up modem chipsets come exclusively from Conexant. Serious problems at Broadcom, including long chipset lead-times, would significantly reduce Zoom’s shipments.

We have experienced delays in receiving shipments of modem chipsets in the past, and we may experience such delays in the future. Moreover, we cannot assure that a chipset supplier will, in the future, sell chipsets to us in quantities sufficient to meet our needs or that we will purchase the specified dollar amount of products necessary to receive concessions and incentives from a chipset supplier. An interruption in a chipset supplier's ability to deliver chipsets, a failure of our suppliers to produce chipset enhancements or new chipsets on a timely basis and at competitive prices, a material increase in the price of the chipsets, our failure to purchase a specified dollar amount of products or any other adverse change in our relationship with modem component suppliers could have a material adverse effect on our results of operations.

We are also subject to price fluctuations in our cost of goods. Our costs may increase if component shortages develop, lead-times stretch out, fuel costs rise, or significant delays develop due to labor-related issues.

We are also subject to the Restriction of Hazardous Substances Directive (“RoHS”) and Consumer Electronics Control (“CEC”) rules discussed above, which affect component sourcing, product manufacturing, sales, and marketing.
