SiTime Corp

Very strong Q1 2026 results; major profitability expansion - Revenue $113.6M, +88% YoY (sequentially ~flat vs Q4). - Gross margin 64.5% (+7.1 pts YoY). - Operating margin 28% (up from ~3% in Q1 2025; +25 pts YoY). - Non-GAAP EPS $1.44 (vs $0.26 prior-year; ~5x increase). - Key mix driver: CED (Communications/Enterprise/Data center) grew fastest and lifted margins; consumer mix was lower in Q1.

CED / AI data-center momentum is the clear engine (and tied to inferencing + optical bandwidth) - CED revenue $75.7M = 66.6% of total, +158% YoY and +17% sequentially. - Management attributes strength to (1) more inference workloads (2–4x more timing content per system vs training) and (2) higher data-center networking/optical bandwidth, including expectation for 1.6 terabit optical modules in 2026 with stronger adoption dynamics. - Product/performance: new Elite 2 Super TCXO family provides up to ~3x better synchronization than prior Elite; positioned as higher ASP/high-margin.

Full-year and Q2 outlook raised/confirmed; strong guidance implies sustained momentum - Full-year 2026 revenue growth expectation increased to at least +80% (vs prior expectations; above the company’s long-term 25–30% model). - Q2 2026 guidance: - Revenue $140M–$150M (>100% YoY at midpoint). - Gross margin ~65% ±1. - OpEx $46M–$47M (continued investment). - Non-GAAP EPS $1.85–$2.00 (assumes ~27.5M share count). - Implicit expectation: CED remains hot in Q2, while other segments contribute steadily (mobile/consumer expected to be comparatively stronger in the second half).
