Case Study: Major Aerospace Manufacturing Company achieves $1.7M in annual cost savings and boosts employee benefits engagement with Castlight Health

Helping employees make optimum use of benefits programs and services

A major aerospace manufacturer offering a strong compensation and benefits package struggled to get employees to use its health and wellness programs. Traditional mass emails and flyers weren’t guiding people to the right care—an issue that became more pressing during the company’s 2014 shift to a consumer‑directed health plan (CDHP).

The company implemented Castlight’s Action module to deliver personalized, timely outreach that segments employees by need and nudges them to the right programs and providers. Outcomes include 66% registration, more than 4,297 employees engaged (with over 1,800 taking meaningful actions), higher return use of the platform, and a 9.6% lower healthcare spending trend—about $1.7M in annual cost avoidance—while requiring minimal extra effort from benefits staff.
