Growing Order Flow: Received purchase orders of $3.3 million including for the demonstration project. Additional POs are expected in July with product backlog expected to exceed $8 million.

Successful Data Center Developer and Partner Demonstrations: Hosted four in-person visits and two virtual demonstrations. Further visits are scheduled in July. The data center developers are of different sizes but collectively represent more than 1GW of installed capacity.

Seeing firsthand how a data center can use our chiller to unlock profits using dynamic fuel switching or operate through a power outage without losing cooling has strengthened customer interest and accelerated deployment discussions.

Addition to the Russell Microcap® Index: Tecogen was added to the Russell Microcap® Index as part of the 2026 Russell U.S. Indexes reconstitution, enhancing institutional visibility.

Russell Reconstitution
Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for active investment strategies. The June Russell US Indexes reconstitution captures up to the 4,000 largest US stocks as of Wednesday, April 30th, ranking them by total market capitalization. Membership in the Russell Microcap® Index, which remains in place for half a year beginning 2026, means automatic inclusion in the appropriate growth and value style indexes. FTSE Russell determines membership for its Russell indexes primarily by objective, market-capitalization rankings and style attributes.
