This is due to fault of Intel. They didn't bet on EUV Lithography. They didn't think it was worth the investment which needs to be made for their fabs in US. Upgrading to EUV is no joke, it requires different manufacturing process and tolerances. Intel having achieved near monopoly in PC market by crushing AMD through unethical kickbacks given to OEMs thought customers will STFU and buy their products. That was until AMD which was near bankruptcy in 2014 rebounded and came in new avatar in the form of Ryzen chips which made a huge difference in the PC market.
Intel will reportedly delay its introduction of EUV until 2021, while TSMC and Samsung hope to have the tech online by 2019.

In 2015 they still wanted to milk 14nm process as much as they can.

Now they are literally buying up all the new NA-EUV machines to keep up with the competition.
Intel is looking to corner the market on high-NA lithography.
