Calare Commemorates Groundbreaking of MACOM’s Global Corporate Headquarters

April 27, 2017

New 58,000 SF Class A office building to enhance the company’s existing manufacturing facilities to establish a unified world-class corporate campus in Lowell

Calare Properties (Calare), a private Massachusetts-based real estate investment firm and operator, commemorated the groundbreaking of
MACOM Technology Solutions Inc.’s new global headquarters on Chelmsford St. in Lowell. The state-of-the-art property will join MACOM’s current R&D
and manufacturing facilities, at 100 Chelmsford St. and 121 Hale St., to create a world-class corporate campus environment owned and developed by Calare

Following Calare’s acquisition of 100 Chelmsford St. earlier this year, the firm has partnered with MACOM, a leading supplier of high-performance analog
RF, microwave, millimeterwave, photonic semiconductor products and components, to develop the adjacent property at 144 Chelmsford St. with a goal of
establishing a cohesive and engaging corporate campus setting on the 15-acre site where MACOM has secured a 20-year lease for the entire campus. The
new 58,000 sf Class A office building is anticipated for a 2018 delivery and will feature a sleek, modern design with high-end finishes and floor-to-ceiling
windows enhancing natural light. With the development of this new property, MACOM and Calare plan to collaborate to remodel the current manufacturing

“As owner and developer of this dynamic site, Calare is thrilled to help write the next chapter of MACOM’s success at this flagship property and support
the company’s vision in establishing a premier corporate campus setting that unifies modern office, manufacturing and R&D space in a creative manner,”
said Bill Manley, CEO and CIO of Calare. “The delivery of a world-class facility such as 144 Chelmsford is a notable step forward for this flourishing
market where existing manufacturing and industrial space has been limited.”

The MACOM business has been based at 100 Chelmsford for over 25 years, and MACOM has leased the adjacent property at 121 Hale Street, which is also owned
by Calare, for the past three years. The company is a leading supplier of high-performance analog RF, microwave, millimeterwave and photonic semiconductor
products that enable next-generation Internet and modern battlefield applications. A pillar of the semiconductor industry, the company thrives on more
than 60 years of expertise in complex problem-solving for applications ranging from RF to Light.

“MACOM is collaborating with Calare to expand and modernize our global headquarters here in Lowell,” said Robert Dennehy, Senior Vice President of Operations
at MACOM. “Our goal with this expansion is to attract people who are committed to inclusion, industry and innovation, and with Calare’s insight, our
global headquarters will mirror that goal.”
