Sachin Shah

CEO, Brookfield Renewable Partners L.P.

As you know, we recently agreed to merge our subsidiary, TerraForm Power, into Brookfield Renewable on an all-stock basis.

The merger will simplify our structure, diversify our holdings, and strengthen our business in North America and Europe, all with continued sponsorship from Brookfield Asset Management.

As a reminder, this transaction will increase our public float of shares by approximately $1.5 billion and will facilitate the issuance of Brookfield Renewable Corporation’s shares, known as BEPC shares, which should help current shareholders who may prefer to hold a C corp share, and may potentially attract new shareholders.

MD and Research Analyst, National Bank Financial, Inc. (Research Division)

So, I wanted to ask you about BEPC. If you look at your sister company, Brookfield Infrastructure, we’ve got BIPC trading at a significant premium to the units today. Do you have a view on whether or not the same conditions are in place for that to happen with BEPC and whether or not it’s an issue, in your mind?

Wyatt Hartley

CFO, Brookfield Renewable Partners L.P.

Yes, so Rupert, I think just for the broader call, what you’re referencing is that, in the context of BIP and BIPC, that BIPC is generally trading at a 5% to 10% premium over the last two weeks, call it, compared to the BIP unit.

Our general takeaway is that we had launched the C corp share because we thought that there would be significant demand for a C corp share. Just providing investors the optionality of investing in a C corp or the LP units was a beneficial thing.

And I think with the shares trading -- in the case of BIP trading above the unit -- that clearly shows that there is a pent-up demand for the shares, and we think that will apply equally to BEP in terms of the demand. BEP and BEPC is a little bit different, in the sense that our original market capitalization on BEPC will be a bit bigger, just because of

the way we were able to structure the transaction, and then if we’re also successful in closing the transaction, so that may impact it a lot -- a little bit.

But our general takeaway, ignoring the premium that we’re seeing right now, because that may normalize over time -- we’ll have to see, as time progresses -- but the reason for offering the share, which we think is strong demand for it, has clearly been borne out in the infrastructure instance, and we think that it will be the same for our vehicle as well.

The only thing I would add, Rupert, is that it’s still early days. I mean, clearly, on the infrastructure side, what we’ve seen is a very significant tick-up in retail interest, which makes sense, because it’s an easy tax filing.

I would suspect you’re going to see a lot of investors who maybe held out because of the tax filings now come into our offering of BEPC as well.

As far as this value difference, though, I would say we’re going to be a little bit patient and just wait. I think it’s going to take a while for it to all settle out, and you shouldn’t expect over the long term to have that difference in valuation.

Rupert Merer

MD and Research Analyst, National Bank Financial, Inc. (Research Division)

In any case, it must look attractive to TerraForm shareholders at this point, I would think.

Sachin Shah

CEO, Brookfield Renewable Partners L.P.

Yes, you know, from a TerraForm perspective, you’re trading an existing C corp for another C corp, so I think it is a nice feature for them to have, and it’s one where if you don’t like it, you can always exchange it on a one-to-one basis with the LP unit. So, you know, we’re trying to give people maximum flexibility and options to meet whatever various considerations they have.

Frederic Bastien

MD & Equity Research Analyst, Raymond James Ltd. (Research Division)

Just a couple follow-up on Rupert’s question. Any lessons you’ve learned -- taken from this BIPC transaction, as you close in on yours?

Sachin Shah

CEO, Brookfield Renewable Partners L.P.

Hey, Frederic, it’s Sachin. You know, I think, look, instinctively, we always try to balance the tradeoff between giving investors options versus putting things out there that could potentially create confusion.

And I’d say, in this instance, that was one of our debates was, you know, is this -- are people going to like this? Will they see it for what it is, which is an economically equivalent security, but one that offers a more simple tax filing profile to it?

And I think credit to the infrastructure team, they’ve done a great job getting out there and explaining it to people, and we’re obviously going to benefit from that coming up second. And I think, looking at this short period under which these securities have traded, it looks like, you know, the retail investors and some institutions have really understood the merits of the C corp share.

And if that lasts, then from our business perspective, I think it will attract a lot of U.S. investors, and potentially a lot of European investors, which I think is really important for our business, because renewable stocks tend to get more profile in Europe, and there tend to be more funds that are directed towards ESG investing or green investing.

And if they can acquire our C corp shares because it fits in with their structure, that could be really good for the underlying demand of our stock and for the overall liquidity of our securities position.
