BACK TO THE 2021 GIANTS 400 LANDING PAGE

In its 2021 Life Sciences Real Estate Outlook, JLL predicted that access to talent would be a primary concern for an industry sector that had been growing by leaps and bounds. A year later, talent still guides real estate decisions. But market conditions of a different sort were cooling the biotech field: namely, investors that have soured on startups which underperformed after going public. What this means for new construction and renovation going forward is unpredictable, as the drivers behind life sciences’ surge are still palpable.
