You’ve Exceeded the SEC’s Traffic Limit

Your request rate has exceeded the SEC’s maximum allowable requests per second. Your access to SEC.gov will be limited for 10 minutes.

Current guidelines limit each user to a total of no more than 10 requests per second, regardless of the number of machines used to submit requests. To ensure that SEC.gov remains available to all users, we reserve the right to block IP addresses that submit excessive requests.

The block will be lifted automatically by waiting 10 minutes. Continuing to exceed the SEC’s maximum allowable request rate during the time-out period will extend the duration of the time-out period. To ensure fair access for all users, please reduce the rate of your requests and visit SEC.gov again after the 10 minute time-out period has passed.

“Excellent commercial execution delivered exceptional first quarter results and positions IDEXX for continued strength through 2026,” said Jay Mazelsky, President and Chief Executive Officer. “IDEXX Cancer Dx™ platform momentum continues to build with the recent International launch and growing adoption in the U.S., and our IDEXX inVue Dx™ roll-out further advances our innovation-driven growth strategy. Initial customer response to the controlled launch of IDEXX inVue Dx FNA has been very encouraging and supports broadening access over the remainder of the year. As I transition from the CEO role, IDEXX remains well-positioned for continued success, and I look forward to continuing to work with Mike Erickson to drive long-term sustained growth in the business.”
