  • Corning’s revenue growth over the recent years was partly driven by increased demand for gasoline particulate filters, given the increased adoption of the emission regulations in Europe and China.
  • Corning has benefited from a pickup in demand for optical fiber as carriers continue to expand their 5G coverage. However, its display technologies sales have trended lower due to a decline in volume and lower demand in the smartphone, tablet, and notebook markets, which have weighed on the specialty materials business.
  • Furthermore, supply chain constraints and the impact of China lockdowns have weighed on its top-line growth in the recent past.
  • West Pharmaceuticals Services saw its sales expand for its proprietary products, including Westar and NovaPure, along with solid demand for its products related to the Covid-19 vaccine and treatments.
  • Although the demand for Covid-19-related products has been on a decline, its proprietary products sales haven’t declined meaningfully in recent quarters, led by price increases and higher sales of non-Covid-related products.

  • Note that we have different methodologies for companies negatively impacted by Covid and those not impacted or positively impacted by Covid while forecasting future revenues. For companies negatively affected by Covid, we consider the quarterly revenue recovery trajectory to predict recovery to the pre-Covid revenue run rate. Beyond the recovery point, we apply the average annual growth observed three years before Covid to simulate a return to normal conditions. For companies registering positive revenue growth during Covid, we consider yearly average growth before Covid with a certain weight to growth during Covid and the last twelve months.
