** Deutsche Bank upgrades Austria Technologie & Systemtechnik (AT&S) ATSV.VI to "buy" from "hold", as an acute shortage of substrates used in microchips translates to higher selling prices for the circuit board manufacturer
** The rise of demand for agentic AI and central processing units has increased the prices of integrated circuit substrates, DB says
** The broker adds AT&S has left behind periods of excess capacity and balance sheet stress, and is well positioned in a market shaped by rising demand from customers like Intel INTC.O
** It also notes the company can now make use of its shell facility in Kulim, Malaysia, which long sat idle
** Shares of AT&S are up 7.6% at 1145 GMT and could see their biggest one-day rise since November if the gains hold
