Renesas sells timing unit, quake hits plants, launches new AI memory chip
◆
Renesas completes sale of timing business to SiTime Renesas sold its timing business to SiTime, which had about 70% gross margin and $300M annual revenue, mostly from AI data centers. This frees up cash but removes a profitable, fast-growing unit. The CEO joining SiTime's board and a planned collaboration on MEMS resonators could create future opportunities, but the net effect on Renesas's value is unclear.
This is a major strategic move that changes Renesas's business mix and could affect future growth and profitability.

Kumamoto earthquake halts production at two Renesas plants A magnitude 7.1 earthquake on July 29 forced Renesas to suspend operations at its Kawashiri and Nishiki plants for cleanroom inspections. No injuries were reported, but wall cracks and water leaks occurred. This disruption can delay chip shipments, raise costs, and hurt sales if it lasts, which is negative for the stock.
The earthquake directly disrupts Renesas's manufacturing, threatening near-term revenue and supply.
▲
Renesas resumes Nishiki plant, aims to restart Kawashiri by Aug 5 Renesas quickly resumed production at its Nishiki plant and targets restarting the Kawashiri plant by August 5. This fast recovery reduces the negative impact of the earthquake. While other semiconductor plants in the region remain shut, Renesas's ability to bounce back quickly is a positive sign for its operations and customer confidence.
The speed of recovery limits the damage from the earthquake, which is positive for the stock.

Benchmark Initiates SiTime Coverage With Buy Rating and $850 Target
Benchmark analyst Gary Mobley initiated coverage of SiTime Corp. with a Buy rating and an $850 target price on August 20, citing the growing relevance of precision timing for system manufacturers. SiTime reported second-quarter net revenue of $157.4 million, up 127% year-on-year, with adjusted gross margins of 67.1% and adjusted net income of $65.6 million, or $2.34 per diluted share, while carrying $1,921 million in cash, equivalents and short-term investments. The company completed its acquisition of Renesas Electronics' timing business on July 1, adding more than 550 clocking products to its portfolio and a business that serves over 10,000 customers, generates close to 75% of its topline from the AI-Datacenter-Comms market, and is expected to bring in at least $300 million in revenue over the next 12 months. Mobley's bullish case also rests on Apple's increasing reliance on its internal cellular modems, which could help SiTime generate annual revenue in the high-$100 million range once Apple's entire product portfolio shifts away from Qualcomm modems. Risks include integration complexity from the Renesas deal, heavy concentration in AI datacenter communications, and added leverage and potential dilution from the convertible senior notes issued to fund the acquisition.

Renesas to Phase Out Production at Takasaki Factory Within Two to Three Years
Renesas Electronics Corporation has decided to phase out production at its Takasaki Factory in Gunma Prefecture, Japan, within the next two to three years, while maintaining and strengthening research and development functions at the site. The factory, operated by subsidiary Renesas Semiconductor Manufacturing, runs a 6-inch wafer line where aging equipment and discontinued support for production materials have made continued manufacturing increasingly difficult. Renesas will gradually scale down operations, building necessary inventory to ensure stable customer supply before the eventual factory closure. The R&D functions, currently focused on analog ICs and discrete power semiconductors, will be repositioned to support development for data center and automotive applications, which are strategic growth areas for the company. Details on the production discontinuation timeline and R&D restructuring will be announced once finalized, and Renesas plans to maintain employment for affected workers through reassignment and career support.
