Previous wording

The ability to accurately measure and reference time has been essential to many of humankind’s greatest inventions and technological advances. Timing technology has continued to evolve over centuries, forming a critical aspect of broader technological evolution. Timing is the heartbeat of digital electronic systems, ensuring that the system runs smoothly and reliably by providing and distributing clock signals to various critical components such as central processing units, communication and interface ICs, and radio frequency components. As electronics evolve to deliver higher performance levels, even in increasingly challenging environments, while also being more complex and size-constrained, we believe they will require more semiconductor-based sophisticated timing solutions that cannot be developed in legacy quartz crystal-based technologies. Precision timing, a category that we created (“Precision Timing”), fills this need with the performance, power, size, and cost that is required by these new applications.

Our current solutions include various types of oscillators, as well as clock ICs and resonators.

Previous wording

At the heart of our Precision Timing solutions are our MEMS, analog/mixed-signal, and systems technologies. We have a deep understanding of mechanical, electrical, and thermal properties of materials, which is a key requirement for developing our proprietary MEMS processes. To maximize MEMS first-silicon success, we have also developed our own MEMS simulation tools. Our analog/mixed-signal die are developed using industry-standard processes and deliver high levels of performance using programmable phase-locked loops, temperature sensors, regulators, data converters, drivers and other building blocks.

Current wording

Our all-silicon solutions are based on three fundamental areas of technical expertise: MEMS, analog mixed-signal design, and advanced system-level integration. This expertise enables us to design silicon MEMS resonators, analog circuits, as well as systems and packaging, and bring these all together to deliver a system-level solution that synergistically solves customers’ complex timing problems. In this aspect, we believe we are different than quartz-based timing providers, who typically have expertise in designing and manufacturing resonator components, but usually outsource the analog circuit design and packaging. We also have a deep understanding of the mechanical, electrical, and thermal properties of materials, which is a key requirement for developing our proprietary MEMS processes. To maximize MEMS first-silicon success, we have also developed our own MEMS simulation tools. We are also different in that our MEMS resonators are made using semiconductor technology which has significant benefits in features, performance, manufacturing, and cost, while the quartz resonator and oscillator suppliers use quartz crystal material

Previous wording

We operate a fabless business model, allowing us to focus on the design, sales, and marketing of our products, quickly scale production, and significantly reduce our capital expenditures by using the semiconductor industry manufacturing infrastructure. A fabless infrastructure gives us production flexibility and the ability to scale capacity up and down quickly to meet demand. Our programmable architecture also plays a key role in ensuring optimal production flexibility, as it allows us to offer shorter lead times and the ability to meet custom requirements more easily.

Current wording

We operate a fabless business model, where we outsource manufacturing to semiconductor industry suppliers, which allows us to focus on, and excel in, the design, marketing, and sales of our products. A fabless infrastructure gives us production flexibility and the ability to scale capacity up and down to meet demand. While this model allows us to operate with lower capital expenditure investment than other semiconductor companies that own fabs, we may be required to make such investments from time to time primarily to strengthen our supply chain and optimize our costs. These investments could put downward pressure on our gross margins if demand for our products does not materialize as expected. Further, this model could also subject us to supply constraints, when demand for our products is higher than anticipated, resulting in increased costs and impacting our gross margins. Our programmable architecture also plays a key role in ensuring optimal production flexibility. In contrast to products offered by traditional timing device suppliers, our products are batch produced and then custom programmed to customer needs, allowing us to offer shorter lead times and the ability to meet custom requirements more easily.

Previous wording

In 2020 and 2021 there were a number of industry-wide supply constraints affecting the supply of analog circuits manufactured by certain foundries, including Taiwan Semiconductor Manufacturing Company, and affecting outsourced semiconductor assembly and test providers. We believe that the effects of the industry-wide supply constraints on other timing device suppliers contributed in part to our revenue and gross margin growth in 2021 and the first half of 2022. In 2022 and 2023 macroeconomic events such as rising inflation, fear of recession, equity market volatility, geopolitical tensions, war, decreased consumer spending, lower demand for electronic products following a period of strong demand during the COVID-19 pandemic, supply chain disruptions, and the COVID-19 pandemic measures implemented in China, harmed sales of our products and results of operations. We believe that some of our customers built up inventory of our products in 2022 to overcome the industry-wide supply constraints that occurred in the previous periods and that the macroeconomic events in 2022 and 2023 led to reduced demand for our customers' products, which led to an inventory buildup at some of our customers and their affiliates, partners and contract manufacturers, which has adversely affected sales of our products. We believe that this inventory buildup will negatively impact the sales of our products until such inventory buildup is reduced and could result in decreases in our sales and margins, and could materially harm our results of operations. The future effects of macroeconomic events on our business and results of operations, including inventory levels at our customer and their affiliates, partners, and contract manufacturers as well as demand for our products, are uncertain and difficult to predict. For additional discussion please see Part I, Item 1A "Risk Factors" of this report, especially the risk factor titled “Global macroeconomic conditions have harmed and may continue to harm our business” and “Our revenue and operating results may fluctuate from period to period, which could cause our stock price to fluctuate.”

Current wording

Since our IPO in November 2019, while our revenue has grown, gross margins have improved, and new opportunities for growth for our business have emerged, adverse macroeconomic events including geopolitical tensions and conflicts have substantially increased. In 2020 and 2021, there were a number of industry-wide supply constraints affecting the supply of analog circuits manufactured by certain foundries, including TSMC, and affecting outsourced semiconductor assembly and test providers. We believe that the effects of the industry-wide supply constraints on other timing device suppliers contributed in part to our revenue and gross margin growth in 2021 and the first half of 2022.

We believe that some of our customers built up inventory of our products in 2022 to overcome the industry-wide supply constraints that occurred in the previous periods and that the macroeconomic events in the second half of 2022 and through 2023 led to reduced demand for our customers' products, which led to an inventory buildup at some of our customers and their affiliates, partners and contract manufacturers, which has adversely affected sales of our products. We believe that while this inventory buildup has reduced through the second half of 2023 and in 2024, any further increase could negatively impact the sales of our products and could result in decreases in our sales and margins, and could materially harm our results of operations. The future effects of macroeconomic events on our business and results of operations, including inventory levels at our customers and their affiliates, partners, and contract manufacturers as well as demand for our products, are uncertain and difficult to predict.

Previous wording

Our solutions enable our customers to differentiate their product offerings and position themselves to gain market share. We work closely with our customers to understand their product roadmaps and strategies. Our end customers continuously develop new products in existing and new application areas. We also consider design wins critical to our future success and anticipate being increasingly dependent on revenue from new design wins for our new higher-end products with higher average selling prices (“ASPs”). The selection process is typically lengthy and may require us to incur significant design and development expenditures in pursuit of a design win with no assurance that our solutions will be selected. As a result, the loss of any key design win or any significant delay in the ramp of volume production of the customer’s products into which our product is designed could adversely affect our business.

We derive our revenue from product sales primarily to distributors, who in turn sell to original equipment manufacturers or other end customers. We recognize product revenue, at a point in time, upon shipment when we satisfy our performance obligations as evidenced by the transfer of control of our products to customers. We measure revenue based on the amount of consideration we expect to be entitled to in exchange for products. Variable consideration is estimated and reflected as an adjustment to the transaction price. Depending on the terms of the contract, variable consideration is estimated using either the expected value approach or the most likely value approach. We determine variable consideration at the end of each reporting period, which consists primarily of price adjustments and product returns by estimating the amount of consideration we expect to receive from our customers based on historical experience. Adjustments for the variable consideration has been in the range of 2% to 4% on a quarterly basis for the current year. Our customers have limited return rights under our contracts with them. If variable considerations are anticipated to exceed historical experience, we may adjust our sales returns allowance accordingly to properly reflect our net revenue. Since our performance obligations relate to contracts with a duration of less than one year, we do not disclose the aggregate amount of the transaction price allocated to performance obligations that are unsatisfied or partially unsatisfied at the end of the reporting period.

Current wording

We derive our revenue from product sales primarily to distributors. We recognize product revenue, at a point in time, upon shipment when we satisfy our performance obligations as evidenced by the transfer of control of our products to customers. We measure revenue based on the amount of consideration we expect to be entitled to in exchange for products. Variable consideration is estimated and reflected as an adjustment to the transaction price.

Previous wording

Inventories consist of raw materials, work-in-process, and finished goods and are stated at the lower of standard cost, determined using first-in first out method or market net realizable value. We review and set standard costs to approximate actual manufacturing costs. We perform detailed reviews of the net realizable value of inventories, both on hand as well as for inventories that we are committed to purchase at the end of each reporting period. We write-down the inventory value for estimated deterioration, excess, obsolete and other factors based on management’s assessment of future demand of our inventory. These estimates may include uncertain elements such as our demand forecast. These forecasts are developed based on current backlogs, inputs from our customers, and internal analyses which may consist of customer historical purchasing trends and level of inventory in the distributor channel, actual and anticipated design wins, market and economic conditions, technology changes, new product introductions, changes in strategic direction and other factors. If our demand forecast for specific products is greater than actual demand and we fail to reduce manufacturing output accordingly, we could be required to write down additional inventory, which would have a negative impact on our gross margin. Once written-down, inventory write-downs are not reversed until the inventory is sold or scrapped.

Current wording

Inventories consist of raw materials, work-in-process, and finished goods and are stated at the lower of standard cost, (which approximates actual cost on a first-in first out basis) or net realizable value. The Company reduces excess and obsolete inventories to their estimated net realizable value based on management's assessment of future demand, historical usage of by product, and market conditions. Once written-down, inventory write-downs are not reversed until the inventory is sold or scrapped.
