The recent 26th Annual ROTH Conference, held at the Ritz Carlton in Dana Point, CA, brought 420 public companies and 45 private companies together in a flurry of panels and presentations that offered up a wide view of potential investment opportunities. As they do every year, ROTH Capital Partners produced a remarkable event, featuring hundreds of company presentations and numerous engaging panels at a beautiful seaside location.

Among the conference highlights were four panel discussions on subjects of particular interest to the investing public.

The conference kicked off with the health care panel held on Sunday, “The Commercial Impact of the ACA.” There, panelists delved into how providers and biotechs are preparing their business models to deal with the influx of new patients that recently got insurance for the first time ever.

Immediately following the health care panel was a look at the hot topic of cyber security at “What the Hack?!” There, panelists played a Jeopardy style trivia game that guided discussion of topics that are very much in the public eye after the Edward Snowden revelations and massive data breaches at retailers like Target (TGT) and Neiman Marcus.

Monday saw some solar leaders and experts gather to discuss the future of their industry at “The Latest Trends in the Solar Industry.” This panel discussed the massive upswing for the industry over the last 18 months, the continued growing global demand for their products, the potential solutions for the ongoing trade war between the United States and China, and which new technologies might mean big things for the future.

Finally, “Ready, Set…IPO” capped off the conference panels on Tuesday, presenting expert opinions on what private companies need to keep in mind when they’re considering the move to being publicly traded. The panelists emphasized that going public is no easy feat, and the companies that succeed with such a movie are typically ones that have planned carefully, prepared meticulously, and executed efficiently.

In addition to the in-depth panel discussion, all 420 public companies made investor presentations at the conference in one of seven different presentation rooms that were active around the clock. The presentations were a half-hour apiece, with hour-long “Deep Dive” presentations made on Wednesday morning by BJ’s Restaurants (BJRI) , Lannett Company (LCI) , Gentherm (THRM) , and Landec Corporation (LNDC) .
