According to the companies’ regulatory filings with the Taiwan Stock Exchange, the iPhone’s strong holiday sales helped Taiwan Semiconductor Manufacturing Co. and Hon Hai Precision Industry post record monthly revenues in the month of December. TSMC announced December revenues of NT$69.51 billion ($2.17 billion) while Hon Hai (better known as Foxconn), brought in NT$515.57 billion ($16.24 billion) over the same period. This represents a 40% year-over-year increase for TSMC and a 5% bump for Foxconn.

Both firms were heavily invested into Apple’s iPhone lineup and benefitted from the large number of holiday sales of the popular handsets. One analysis suggested that Apple may have sold as many as 69 million iPhones in the December quarter, a year over year sales jump of more than 18 million units. Despite serious constraints on the iPhone 6 supply that lasted through Christmas, Apple retail outlets in the US recently started to list the devices as “in stock” with no lead time last week.

For those of you who didn’t know, although TSMC has won smaller Apple orders in the past, 2014 marked the first year in which the Taiwanese company was chosen to fabricate Apple’s A-series application processors. The latest A8 chip sits at the heart of the iPhone 6 and iPhone 6 Plus although the iPad Air 2 boasts a slightly faster A8X. Foxconn, meanwhile has a hand in assembling nearly every product in Apple’s product lineup. The company is believed to have as many as 500,000 workers dedicated to its iPhone lines alone and is reportedly investing roughly $2.6 billion into a new display factory that will exclusively serve Apple’s business.

If all continues to go well, it’s likely that Apple suppliers will see larger revenues as Apple continues to grow as well.
