IAC Q1 2017 Shareholder Letter

May 3, 2017

Dear Shareholders,

On Monday, we announced the combination of HomeAdvisor and Angie’s List to create the undisputed leading home services marketplace and deliver another new public company out of IAC.  Not only does the transaction open a wonderfully bright future for our home services category, we also evolve IAC yet again, with substantial stakes in what will become two public companies underneath a single IAC umbrella: Match Group and the soon-to-exist ANGI Homeservices, both leaders in their respective categories with plenty of room to expand.

From what was one singular IAC in 2005, with the completion of this transaction, there will be 10 thriving individual public companies.  HomeAdvisor now joins the ranks of Match, Expedia, Ticketmaster and many others as proof of IAC’s ability to spot categories on the verge of the transformative leap from offline to online, and ride that transition with winning products, and multiple brands driven by talented, incentivized entrepreneurs.  We did it in dating, travel and ticketing, and I have no doubt we’ll do the same with home services.  I think this can be our biggest one yet.

To give you a sense of the impending ANGI Homeservices, on a pro forma basis the entity generated an estimated $17 billion worth of home improvement jobs over the last 12 months for more than 190,000 different U.S.-based paying service professionals (SP’s).  We served over 15 million consumers in the US, facilitating home improvement jobs in over 700 different categories.  Combined revenue would have exceeded $850 million in the last twelve months, driven by growth in HomeAdvisor’s domestic business, which just clocked its 8th straight quarter of growth in excess of 35% year-over-year, all while improving margins.  And Angie’s List has done a wonderful job building a brand, with 46% unaided brand awareness — a rare achievement for any brand in any category.  They’ve done so well that the most frequent response I get at cocktail parties when explaining the HomeAdvisor business is, “Oh, you mean like Angie’s List!”

The strategic rationale for the transaction is simple: combine Angie’s brand-conscious and qualified traffic with the largest paying SP network and most advanced product from HomeAdvisor.  Adding Angie’s traffic, brand, and SP network quickly catapults HomeAdvisor several years into the future.  The increased liquidity in the marketplace enables new product innovation, increased customer satisfaction, faster category penetration and accelerated expansion.

Our investor deck (available here(1)) outlines the rationale and benefits of the deal in robust detail, but I want to take a little real estate in this letter to elaborate on three fundamental indicators of potential:

(i)                                     Market size

(ii)                                  Penetration

(iii)                               Take rate

On market size, we’re already playing in a $400 billion market in just the US.  We think all of Europe is roughly similar.  And yet, the process of getting jobs done in your home remains far too burdensome.  Most people have a home improvement to-do list, stored in their head, with daily reminders when that spot in the floor creaks, or that light in the ceiling flickers.  But the jobs on that list don’t ever get done, because doing so takes too much work — far more complicated than the press of a button by which you can now, for example, order a ride, or a dinner, or diapers.  We believe that as we similarly eliminate friction in home services, more jobs will get done.

On penetration, only 10% of the market is online as of today.  Filling the rest of the jobs is still done offline, largely by word of mouth, where neighbors provide recommendations to neighbors, notwithstanding the reality that their recommendations are constrained by a highly limited data set.  Our product provides the consumer a better set of information (e.g., reviews, qualifications, historical record, and availability) and a faster process by which to connect to the right pro for their job.  I don’t know where that 10% penetration will be ten years from today, but I am certain it will be meaningfully higher.

“Take rate” is an industry term which refers to the amount of revenue collected by the operator of a marketplace (in this case, ANGI Homeservices) as a percentage of the total value of business transacted on the platform.  At the racetrack, they call this “the rake” or “the vig”.  In auction marketplaces, they call it a commission.  Other platforms call it a service fee.  At HomeAdvisor, we estimate that rate is 3-4%, meaning that for every $1,000 in business earned by an SP from jobs they get on our platform, we record and collect $30-40 dollars in revenue.  In many other marketplaces, the rate is much higher, as the more a

service does to help sellers (SP’s in our case) close and measure transactions, the greater the take rate they can command (e.g. Uber, Airbnb, eBay, and others).  Sellers are in fact happy to pay a higher effective rate, so long as the platform continues to generate a strong return on their spend and help make their overall business easier to run.  SP’s want to spend more time doing jobs and less time looking for jobs.  Compared to the tools an SP has historically used to find jobs, such as yellow pages or clicks on search listings, our system provides far more concrete data and tools to measure success.  But we see tremendous opportunity to improve — we just need to help SPs win more jobs for every dollar they spend and show them how it’s happening.  Our platform is already incredibly effective — at a 3-4% take rate, for every $1 an SP spends with us they bring in, on average, $29 of revenue.  (I wish we could find a similar return for IAC’s $1 billion of cash.)  As we drive up that return and continue to show SP’s the results, we expect to see spend on our platform rise in a manner consistent with other marketplaces, all while delivering a better experience for our customers.

We are going to continue to press investment in HomeAdvisor notwithstanding the merger.  With 38% domestic revenue growth and domestic Adjusted EBITDA more than tripling in Q1, we want to invest into strength.  In Q2 we will increase our consumer marketing expenditures with a new creative campaign that launched a few weeks ago to strong early returns (see spots here(2) and here(3)).  We previously mentioned we might target $100 million of TV spend in 2017, up from our previous target of $85 million.  In this quarter, we will start down that path, increasing our TV marketing spend 75% year-over-year and expecting returns to hold.  We are also going to invest further in our dedicated SP apps, tools and support.  Nearly 90% of new SP’s now log into the mobile app within the first two weeks and over 50% of our entire SP network has logged into the app in the last month.  These engagement figures on our mobile apps were previously unthinkable, and we now need a team big enough to keep up with the audience.  With the SP’s regularly engaging with our tools, we can invest considerably in product improvement.  As an example, we are setting up new SP training & onboarding programs with simple reporting tools that will allow every SP to see clear data on win rate and return on investment on every dollar they spend along with tips to help drive their win rate, directly in the app.  Not all SP’s have sophisticated tracking of their marketing dollars, but with our tools they will be able to see how much they spend with HomeAdvisor, how often they win the job, and the corresponding revenue generated from our matches.  With greater accountability, SP’s can start to see a clear path to increased budgets so long as we continue to clearly demonstrate that their business gets bigger as they spend with us.

As we’ve said all along, we aren’t optimizing HomeAdvisor for near term margins.  Q2 margin will be down a little year-over-year with the increased marketing and development spend, but we expect to see

that pull through in accelerating revenue growth throughout the year, and the margin will more than recover in Q3 and Q4.  In general, given marketing and other investments, margin won’t be smooth quarter to quarter, but for the year overall, we have high confidence in our outlook.

Elsewhere in IAC, as you’ll see in our financial release, we delivered a strong quarter.  Applications, Publishing, and Video are on upward trajectories and on pace for the year.  Match Group continues to deliver impressive, predictable and recurring revenue, strong organic growth, low and decreasing leverage, positive working capital dynamics, low capital expenditures, and an attractive cash tax rate.  The organic growth coupled with the free cash flow yield puts Match Group in elite company.

After closing of the Angie’s List acquisition, IAC will control the undisputed market leader in two large consumer internet platforms, each with significant runway.  The opportunities afforded by multiple acquisition currencies and increased financial flexibility are numerous, and we will strive do what we do best — find, build, manage and grow great companies to compound capital for our shareholders.

Full Year 2017 Outlook

Please find below our updated full year 2017 outlook.  We confront investment choices every day, and as stewards of your capital, will deviate from guidance when we have an attractive opportunity that drives long-term value at the expense of short-term results.  And of course, sometimes we’ll simply be wrong about the future.  Amply warned, here’s our current outlook for the year:

(a) Excludes potential costs related to the Angie’s List transaction.

·                  Match Group - $303 to $313 million revenue and $102 to $107 million Adjusted EBITDA in Q2 2017.  2017 full year guidance unchanged.

·                  HomeAdvisor - For Q2, we expect revenue growth in the high 30% range and comparable growth for the full year.  We expect Q2 Adjusted EBITDA margins in the high single digits as we accelerate investments across marketing, sales and product domestically with incremental losses in Europe.  This excludes potential costs related to the Angie’s List transaction.

·                  Video - We expect Video revenue to grow in the low to mid double digits for both Q2 and full year 2017.  We expect Adjusted EBITDA losses in Q2 in the high-single digit range.  The full year range for Adjusted EBITDA losses was reduced to $30-$40 million due to the shift of Vimeo’s proprietary SVOD channel launch to 2018.

·                  Applications - We expect revenue in the $140 to $150 million range per quarter and Adjusted EBITDA at about $30 million per quarter, give or take a little, for the foreseeable future.

·                  Publishing - We expect revenue in and around $70 million in Q2 and at that revenue level, continue to expect Adjusted EBITDA losses of a couple of million dollars with profitability in the second half of 2017.
