For ATS, we expect Q3 revenue flat Y/Y, improving from -5% Y/Y 1H and up mid-single digits sequentially. We expect the stabilization in growth to be driven by subsiding headwinds in industrial, improvement in commercial aerospace, defense program ramps, and further recovery in capital equipment.
Expect CCS growth momentum to continue Q2. Our model calls for CCS revenue to increase 37% Y/Y to $1,474MM (+2% Q/Q) in Q2, with growth stable with 38% Y/Y Q1. We forecast CCS Communications revenue to rise 48% Y/Y to $844MM (+10% Q/Q), in line with guidance for mid-40%. The acceleration in Communications growth (vs. 17% Y/Y Q1) is driven by the ramp of 400G switches. For CCS Enterprise, our model calls for revenue up 25% Y/Y to $630MM (-6% Q/Q), in line with guidance for a low 20% and slowing from 72% Y/Y Q1. The deceleration reflects slower growth in compute (70% Y/Y Q2e vs. 130% Y/Y Q1), on tougher comps and investments shifting to networking. We believe Q2 CCS revenue may exceed our forecast on ramping hyperscaler demand, though OEM is likely to remain soft in Q2. Celestica’s largest customer accounted for 34% of total revenue Q1, up from 22% FY23 and 11% FY22; we believe investors will have a heightened focus on trends in customer concentration and revenue ramp with other large hyperscalers.
Forecast ATS revenue down 7% Y/Y Q2. Our model calls for ATS revenue to decline 7% Y/Y to $805MM Q2 (+5% Q/Q) on continued softness in industrial end markets, primarily in EV charging. Our outlook is consistent with Celestica’s guidance for “high single-digit” Y/Y decline and compares against -3% Y/Y Q1 (-4% Q/Q).
Peer Jabil reported Q3 slightly above consensus, retracts FY25 guidance. On June 20, EMS peer Jabil (NYSE:JBL; not covered) reported Q3/FY24 (May-qtr) revenue of $6.8B, above consensus at $6.5B. The company reiterated FY24 revenue guidance. On May 20, Jabil rescinded FY25 guidance, citing softness in key end markets, particularly EVs and semi-cap equipment. Also, Jabil is shifting its portfolio away from certain end markets, which is an $800MM headwind to FY25 revenue. With respect to AI and data centers, the company noted that it is working on making the transition from legacy networking to the next-generation of networking and switches. The company had previously guided to $6B of AI-related revenue for FY25 (+20% Y/Y).
