Silicon Motion: EPS Beat Masks Negative Free Cash Flow
Silicon Motion Technology beat EPS consensus by 15.2%, with revenue up 127% year-over-year to $1.31 billion, but trailing twelve-month free cash flow stands at -$197 million despite 48.9% gross margin
Silicon Motion Beats Estimates But Cash Flow Lags
NEW YORK, August 21 —
Silicon Motion Technology Corporation (SIMO) is staging one of the semiconductor sector's more puzzling recoveries: revenue up 127% year-over-year to $1.31 billion, yet free cash flow of -$197 million, with the executives who know it best having sold their shares in June at prices the stock has not approached since.
- Most recent quarter EPS of $2.43 vs. $2.11 consensus, a 15.2% beat, the largest absolute-dollar surprise in four quarters.
- TTM free cash flow: -$197 million; operating cash flow -$67 million, despite 48.9% gross margin.
- Five insider sales in June at $300, $328 per share, all above today's $249.65; zero purchases.
The Cash Isn't Following the Revenue
Silicon Motion designs NAND flash controllers sold under the SMI brand (the chip that manages how an SSD reads, writes, and wear-levels data), plus single-chip SSDs under FerriSSD and Ferri-eMMC, serving PC makers, hyperscalers, and smartphone OEMs. That business is growing fast. The cash is not following: operating cash flow is -$67 million and free cash flow is -$197 million on a trailing twelve-month basis. The 48.9% gross margin confirms healthy product economics; the burn falls below that line, in R&D or working capital, and has not produced the cash flow that a DCF model at 15.7x forward earnings requires.
Insiders Sold the Peak, Not the Recovery
The insider record is the most unambiguous data point in the file. Across five Form 4 filings in June 2026, Han-ping Shieh and Kuan-ming Lin sold a combined $1.56 million worth of SIMO shares at prices ranging from $300.00 to $328.00, every transaction above today's $249.65. The pattern is consistent: Shieh sold 1,000 shares at $301.25 on June 2, then both executives sold again on June 17 and 18. Zero purchases were reported in the window. Two executives sold across five open-market transactions at prices uniformly above current trading.

| SIMO | $8.6B | 16.0x | +226.6% |
| MXL | $6.0B | 25.5x | +299.3% |
| MTSI | $20.5B | 31.6x | +111.0% |

| TSEM | $25.5B | 34.6x | +308.9% |
The Thesis Turns on One Number
The bull case rests on the 48% gap to the $369.70 analyst target and the assumption that cash generation lags a NAND upcycle but eventually catches up. At 15.7x forward earnings on a near-zero net-debt balance sheet, the valuation is not demanding if that inflection arrives. Against it sits the insider timeline: Shieh and Lin sold at $300, $328, and no insider has bought the dip. The thesis turns on the next quarterly FCF print; a third negative period makes the target gap look like analyst optimism. Run the free Silicon Motion Technology Corporation deep-dive to track it.
