Lead times: Damned if you do, damned if you don't

Following a third consecutive record-breaking sales quarter reported by programmable logic vendor Xilinx Inc. Wednesday (July 22), at least one Wall Street analyst reiterated his contention that extending lead times by the leading FPGA supplier put it at risk of double ordering.
During an analyst conference call Wednesday, Xilinx CFO Jon Olson acknowledged that lead times have grown longer from the 10 to 12 weeks the company reported during its last earnings call.
"We note Xilinx stated its lead times have extended to over 12 weeks for some Virtex-5 devices (estimated 26 percent of F1Q11 sales), above last quarter’s 10-12 week range," Danely wrote in a report circulated Thursday morning. "As a result, we believe Xilinx is at risk of double ordering. The company stated lead times are unlikely to be reduced until the December quarter due to ongoing supply constraints."
Danely earlier issued the same warning about the other big programmable logic vendor, Altera Corp., which also reported record quarterly sales this week. He noted that Altera reported extended lead times for some parts of up to 26 weeks.
Double ordering is the dreaded phenomenon where customers hedge their bets by placing orders with multiple vendors, fully intending to cancel some orders depending on who can deliver the parts first. It's bad news for everyone and creates a misrepresentation of actual demand that can give suppliers fits.
Danely has warned about Xilinx being at risk for double ordering before, most recently following the company's last quarterly report in May. And analysts have generally been concerned about inventories at Xilinx and Altera for several months.
The disconnect here is that Danely is the same Wall Street analyst who earlier this week raised a red flag because Texas Instruments Inc. was pulling in lead times (though they remain high by historical standards), noting that one of his firm's rules for semiconductor investing is, simplistically, "Lead times coming in is bad."
To recap, Danely warned TI investors that the company was pulling in lead times (much to the relief of TI customers), then later warned Xilinx and Altera investors that the companies were reporting extending lead times. No disrespect to Danely intended, but the logical conclusion is that in his view, the only safe situation is for lead times to remain unchanged. But lead times for most parts are continually fluctuating, as supply and demand struggles to find equilibrium.
While it's difficult to reconcile Danely's advice on TI with his advice on the programmable logic vendors, it should be noted that he and other analysts gave generally very positive reviews to the quarterly results turned in by both Xilinx and Altera, though Danely himself maintains a "neutral" rating on both stocks, citing fears of inventory build and correction (also difficult to reconcile with warnings about extending lead times).
"Despite the lack of improvement in lead times, Xilinx continues to meet critical customer demand and management does not believe they have lost any share to competitors as a result," wrote Hans Mosesmann, an analyst with Raymond James & Associates. "Xilinx expects to be wafer constrained for at least another two quarters, but sees no unusual buffer inventory accumulation."
Mosesmann maintains a "strong buy" rating on both Xilinx and Altera.
Olson said Xilinx could have shipped an additional $20 million or so in revenue during the quarter if not for supply constraints. "We think we can hold at that level through the September quarter and not expand that number, and I think that will be a good thing," he said.
In his research note on Xilinx earnings, Ian Ing, an analyst with Gleacher Co., suggested that the shortfall and supply constraints at 65-nm may be due to Xilinx' declining priority at foundry supplier United Microelectronics Corp. (UMC). After years of being a top-tier customer at UMC, with corresponding privileges, Ing said he believes Xilinx "has little leverage to get highest-tier priority at UMC, as foundry supplies remain tight and UMC best serves its long-term partners."
Xilinx announced earlier this year that it would use Taiwan Semiconductor Manufacturing Co. Ltd. and Samsung Electronics Co. Ltd. as its foundry suppliers for the 28-nm node, forsaking UMC after a more than 10 years of partnership. UMC will presumably continue to manufacture TSMC parts at other process nodes.
Ing maintains a "buy" rating on Xilinx and a "neutral" rating on Altera. He increased his revenue estimates and share price targets for both companies following this week's earnings announcements.
Xilinx traded at $28.50 in midday trading Thursday, up 2.5 percent from Wednesday's close. Altera traded at about $28.30, roughly flat with its closing price Tuesday, when it announced second quarter earnings.
